blog essays College was once a truly unique institution, set-apart, more or less, from the conventions of society. It was freedom institutionalized (ironically enough). Free for the first time in their lives, kids learned quickly that there is more to this world than what mom and dad showed #8217;em. There were boobs, there were drugs, there was life. Oh and wait, politicians aren#8217;t always truthful, either! Really? Yes, man. And answers aren#8217;t always obvious. Really?
Yes. They found a lot of bullshit. They found a lot of hypocrisy. People were dying! #8220;We want peace!#8221; they chanted. So they raged and rioted. Definition? They broke contact with the older generation as much as possible.
They dissociated themselves as much as possible from institutionalized society the man the Opportunistic HIV Infections Essay, main purveyor of the lexicography, evils they had come to hate. Maybe college isn#8217;t the bastion of Strategic, freedom it once was, a small city-state set apart from conventional society. College certainly is no longer the first purveyor of the unholy fruits of truth and innocence lost. Kids see their first pair of tits and smoke their first joint long before they enter the hallowed ground of American higher education. Today, kids wake up long before college. They have a steady stream of unfiltered information coming at them on the TV and on definition the internet. They have learned to decipher the most complex of gadgets with ease. They have been the victims of intense marketing and information overload, and have thus honed their skills at discriminating between the good and Brown, by Nathaniel Hawthorne Essay, bad. We have a legion of kids who know from the cradle not to believe everything they hear especially from authority sources.
They have already rebelled against mom and dad during childhood and teens, so why bother keeping up the charade in lexicography definition college? In fact, their parents are likely divorced, giving another reason for closer contact between parent and child. And Evolution AIDS Essay? Besides, they need the money. Definition? The lack of radicalism, creativity, and and Evolution of the AIDS Virus, individualism at today#8217;s colleges (while often still vibrant) is the result of earlier innocence lost. Kids have already seen #8220;the man#8221; in highschool, in lexicography grade school, on MTV.
They do not need college to tell them that there are significant amounts of bullshit and hypocrisy that circulate in society at large. They do not need college to tell them of the social inequities that exist at home and abroad. They were most certainly exposed to social activism in high school, something our parents rarely encountered. Thus their earlier awakening has taught them at an earlier age to do what adults do. Brown, By Nathaniel Essay? They compromise. If you can#8217;t beat #8217;em, join #8217;em. Lexicography Definition? From the beowulf battles, day the #8220;real#8221; collegiates (our parents, for instance) lowered their middle fingers, shaved, and got a job, from the day they started paying taxes they were compromising with society and with convention.
Once, college students thought they could change the lexicography, world. But eventually they learned to compromise. Adults have long learned that you have to make peace with some of the unruly mechanisms in society in order to function. Sure, smog blows, but few are willing to give up their car without a ready and Strategic Human, available alternative. Yes, corporate America is a den of thieves but people need jobs. Yes, most people probably could distribute tax revenue better than the government, but will they really withhold their taxes? Indeed, compromise is a key aspect to adulthood. Today#8217;s kids are just as savvy. They just learned to compromise at an earlier age.
They don#8217;t necessarily wholly buy the market rhetoric they espouse, but they do realize what sorts of rhetoric moves causes along the pipeline. They realize the key to definition, change is to work from the inside out. This same mechanism of compromise is seen in our college students today. Perlstein notes the #8220;isolated-village#8221; college once was, free from the philosophical dictates of leaders at large. He is surprised to encounter the a symbolic-interaction of sports would that, market-savvy rhetoric of college educated youth in discussing, for instance, the genocide in Darfur.
These terms, Perlstein figures, are indicative of the definition, ruling class the government, #8220;the man#8221;, everything and anything any college kid worth his salt would avoid like the plague. These kids have already lost their innocence, and and Evolution AIDS Virus, have decided it is better to work with the system than to utterly abolish it. They have learned to definition, speak in the language of adults. This is the language which adults understand, and to which they listen. Of course, these kids are still pushing their own agendas, cloaked as they are beneath adult-speak.
And of course, there still is radicalism at college. There still are those willing to stand strong against the powers that be, to stand strong against Goodman Brown, by Nathaniel Hawthorne, the hypocrisy they see in the government, and in their communities. Loss of innocence is due to lexicography definition, the age we live in. Children are bombarded with unfiltered info from television and the internet at beowulf battles, an early age. They are the definition, victims of mass-marketing from the time they appear in the cradle. Their ability to decipher and sift through information is early enhanced. They can#8217;t believe everything they hear because they hear way too much. Goodman Brown, By Nathaniel? Thus, their discriminatory powers and bullshit detectors are early exercised. Yet, it is precisely this information age that make colleges more necessary than ever.
They are needed to educate and lexicography, aid our youth in navigating a world that grows increasingly complex. To this end, the college has evolved to reach this new era of students, an era of early-enlightened children, who have made their deal with the devil, and yet will work to Opportunistic, their own ends subtly, yet surely. Barbies on Wall Street: College for the Students#8217; Sake. During my first few weeks at Vassar, I was a closeted homosexual who only wore dull, frumpy sweatshirts and never said a word. Lexicography? But after a while, I met an eclectic bunch of people, never went to Young Goodman Brown, Hawthorne Essay, bed before one a.m., and spent a few days venturing out to contemporary art galleries in Manhattan.
Now I wear pink sweatshirts and talk quite frequently. So as I read Perlstein#8217;s article, I began to realize how different my experience at Vassar seemed from the dreary, corporatized atmosphere surrounding the University of Chicago, the school where, as a friend of mine once grimly put it, #8220;fun goes to die.#8221; Sure, many of my peers are career-minded and nearly all are academically resolute, yet there is always a childlike blitheness around campus that never ceases to pull us through even the lexicography definition, most stressful pre-examination periods. Indeed, as Perlstein notes, the gap between childhood and college has shortened, but not solely in and Evolution Essay the sense that, because of the definition, Internet, pre-college students now have more information and Strategic Human Resource Management Essay, ideas at their fingertips than ever before. Despite this, there is still a very genuine, nostalgic attachment to carefree elementary school days that I have noticed not only in Vassar students, but also in my friends at home, many of whom are still eager to revel in classic Disney movies, immerse themselves in the latest Harry Potter book, or, as a friend and I once decided to do, organize a Barbie party. But what could all this mean? Have university students just become more puerile since the 1960s and lexicography, 70s? Probably not, if Perlstein#8217;s account of the University of little, Chicago#8217;s uncreative, humdrum zeitgeist is accurate. But therein lies my major objection to Perlstein#8217;s article: although it implicitly claims to be a barometer of the current collegiate psyche, its lack of lexicography definition, any mention of any other school besides the University of Chicago (save for Strategic Human Management Essay, the brief allusion to definition, the heady Berkeley campus of 1966 in the introduction) immediately strips itself of that title. Perlstein tries to acknowledge his expository dilemma at one point in the article: #8220;Is their diagnosis [that life at Chicago is #8220;infantilizing#8221; and Opportunistic HIV Infections Essay, #8220;emasculating#8221;] a function of college itself today, or just this college?
Hamilton Morris told me stories that suggest the former.#8221; Yet the acknowledgment is ultimately self-defeating if Perlstein does not report on other institutions as well. Besides, I doubt that Hamilton Morris#8217;s #8220;stories#8221; of frustration with school (notably the lexicography definition, one in which his guidance counselor at Chicago curtly notifies him that he is #8220;not right for little, college#8221; and should drop out) could really suggest the former if all of lexicography definition, them deal specifically with the little, University of Chicago. Even Morris#8217;s classmate#8217;s declaration that #8220;college sucks anyway, so I might as well stay here,#8221; albeit a broad sentiment, is still too subjective to indicate a mass opinion. Lexicography? In all fairness, however, I certainly cannot label Perlstein as myopic without also acknowledging that my own observations of happy-go-lucky university life are innately blinkered, since I only have experience at one institution. But taking both of our accounts into consideration (and assuming that neither is a completely isolated, atomized instance), something quite telling stems from their contradiction. Campus life may be starkly different between Vassar and Chicago, but Perlstein fails to a symbolic-interaction analysis of sports, indicate explicitly that it is the students themselves, whether carefree or careerist, who determine the university scene. It is definition fine to claim that many Chicago students have become #8220;cogs in the organization,#8221; but there is one blaring fact that Perlstein leaves out here these students are not working so diligently for the organization, but for Goodman Brown, by Nathaniel Essay, themselves. They may become bleary-eyed and crabby in the process, but at least they#8217;re suffering for lexicography definition, their own ends.
What we have in the modern university student, then, is really an increased self-awareness that is neither necessarily egotistic nor overtly independent. Beowulf Battles? Too often, students receive admonishments for an apparent social and political lethargy that are founded solely on an unnecessary comparison with the more politically active campuses of the definition, 1960s and 70s. In fact, many schools can still boast a heady political scene the old standbys of College Democrats and College Republicans have not gone away, but have been joined by Amnesty International and beowulf battles, ACLU chapters, Habitat for Humanity affiliates, and, at least at lexicography definition, Vassar, campaigns to stop the evils of the Coca-Cola Company. Even though the media might not notice, many of us genuinely care about current affairs. But that does not mean we have to care if we don#8217;t want to, especially in an environment where more of an emphasis is placed on individual edification than on social activism. No matter how apathetic and unmotivated it may seem, we can still reserve the right to unabashed political lethargy. The campus as campaign center, part of the #8220;college experience#8221; that Perlstein describes, may have lost its cultural significance, but college students most certainly have not. The populistic phenomena of Facebook, YouTube, and the like, although admittedly distracting, indicate a more active desire in college students to place themselves outside of their university bubbles, if not into the real world, then into the digital one. To post a picture on Facebook or a video on YouTube, regardless of the content, is to fish out a line of hope that someone will notice it.
Although this may seem like a collective case of dependence anxiety, what it actually reveals is a situation of self-advocacy. Analysis Of Sports Would Conclude? On Facebook, for instance, one can add friends, join groups, list interests and lexicography, activities, post notes, deliver and receive comments in a sense, network one#8217;s specific traits as an online acquaintance. By no means are modern university students detached from the man computer, world beyond the college gates the Internet still holds the definition, possibility of informing us of the current goings-on, but it also allows us to extend ourselves into our own digital personae, mapping out our own spaces on and Evolution of the AIDS Virus the web. Obviously, we do not go to college to discover ourselves on lexicography the Internet. Yet Perlstein#8217;s distinction between college and man computer, college, between necessary process and liberating experience, still does not explain why we do. His article implies so much about the contemporary university student#8217;s life the individualization, the effects of the Internet, the shortened childhood-college gap yet it stops short of a deeper, broader understanding of the situation. In a sense, the #8220;college experience#8221; has not completely gone away it#8217;s just taken on a different form.
We might be a little less naive going into college than were previous students, but we still retain an excitement for our future advancement, whether corporate or creative, that we hope will begin if not in school, then because of it. Both college and college still remain crucial aspects of modern American life but only if we students get to choose the typeface. There has been a great loss in the level of activism among college students since the turbulent 1960s. Complacency reigns over the people. Today#8217;s twenty-something, anarchist-punk, bicycle-messenger population is dwindling. Lexicography Definition? Those that have survived are crestfallen. The man with the thin gray goatee and a framed photograph of himself looking hairier and suspiciously uninhibited in 1972 laments, if only half seriously, that the ire of this young generation cannot seem to be adequately risen.
It was different when he was young, he#8217;ll tell you. In the Strategic Essay, 1960s, you weren#8217;t a major city if you didn#8217;t have your own race riot: from Baltimore and D.C. to Watts, to lexicography, Newark and New York and everywhere else. Essay? But it was more than race and it was more than war, the world was changing and college campuses held all the promise the future could hold. I am one of those young people who the man with the thin gray goatee lectures about social action. For me, Kent State is college basketball. Lexicography Definition? For him, Kent State will always be four dead at the hands of the Ohio National Guard. Time changes more than clocks. I take classes at Temple University, a school in North Philadelphia known for man computer, its diversity and lexicography definition, surrounded by a long history of activism.
Philadelphia is certainly a major city, so, of course, we, too, had our own 1960s race riot, a charming, two-day affair that resulted in more than 300 injuries and nearly 800 arrests in Origin Essay August of lexicography, 1964. The south end of Temple University is marked by Cecil B. Little Man Computer? Moore Avenue, named for definition, a legendary civil rights lawyer in beowulf battles Philadelphia. Today, at Temple, Cecil B. Moore means a row of residence halls and as far south as many students will walk at lexicography definition, night. Before, Cecil B. Moore was who brought the Rev. Dr. Strategic Management? Martin Luther King, Jr. to Philadelphia almost a year to the day after those race riots. Time changes more than clocks. In the summer of definition, 1965, Moore was in the midst of leading what would be an 8-month picket of Girard College, a private, then-segregated school for underprivileged, orphan boys. When King showed up on a hot day in Young Brown, by Nathaniel August, he addressed 3,000 demonstrators massed outside the school. #8220;It is a sad experience to stand at this wall in the 20th century in Philadelphia, the cradle of liberty,#8221; he orated as King was known to orate. #8220;It is a kind of Berlin Wall to keep the colored children of God out.#8221; Time tells that three years later, after state and federal court appeals, that that racial wall finally fell and the first black students were admitted.
Things like that were happening everywhere in the country, everywhere in the world, the man with the thin gray goatee adds proudly, as if he really believes that back then one man with long hair and good music could change the lexicography, world. No one believes that anymore. Time changes more than clocks. They were times of excitement and confusion and fear. My own grandfather was moved enough to keep a .22 caliber rifle underneath the bed of his Long Island home, which was nestled, in his mind, uncomfortably between New York City to the west and established black communities to little, the east. Why don#8217;t the children of today terrify middle-aged suburbanites into gun ownership? My generation has had our moments, but they are few, far in between, and seemingly less constructive than those of the past.
Fifteen years ago, more than fifty died in the chaos following the Rodney King verdict in Los Angeles. Even more recently, Ohio has seen two well-publicized movements, one following a 2001 police shooting in Cincinnati and a 2005 reaction to a neo-Nazi rally in lexicography Toledo. My own North Philadelphia campus has seen social action during my lifetime. Two years before #8216;Rodney King#8217; became a household name, a brawl of some 600 students turned into days of protests on Origin and Evolution of the Virus Essay North Broad Street, as students demonstrated against what they felt were racially-charged, overly-aggressive tactics by university police. What about that? I ask the man with the thin gray goatee. Those demonstrations might be more emblematic of our generational differences than anything, he counters as a father would counter a child too young to know anything.
It was fought and, by some standards, won, as Temple incorporated race courses into the university#8217;s core curriculum, but, unlike the movements of the 1960s and 1970s, there wasn#8217;t staying power. Walk around Temple#8217;s campus today and lexicography definition, it would be unlikely to find anyone who remembers campus rioting as recent as 1990. The man with thin gray goatee is right. That breed of social action isn#8217;t my generation#8217;s specialty. My peers and I have forgotten the great struggles of the beowulf battles, past, we are without Kennedys and Kings, and we aren#8217;t nearly as organized. The man with the thin gray goatee thinks that that means social action is dead, but I think he#8217;s wrong.
Young people today are just doing things differently. Rather than staging a sit-in to lexicography, encourage Gerald Ford to bring troops back from Vietnam, young people today are more likely to tutor someone younger or shovel the driveway of someone older. A recent survey of college freshmen suggested the beowulf battles, highest interest in volunteerism in lexicography definition decades. In the survey, sponsored by the University of Maryland#8217;s Center for Information and Research on little Civic Learning #038; Engagement and conducted in the spring of 2006, more than one in three people interviewed had volunteered that year. Like the 1960s and 1970s, these changes are happening on campuses first. The number of collegiate volunteers blossomed by more than 20 percent between 2002 and 2005, an additional 600,000 young do-gooders, according to the Corporation for National #038; Community Service, a federal agency. Young people of the future won#8217;t interact with their surrounding world the same as today, just as today#8217;s youth don#8217;t do it as those of the past did. Lexicography Definition? Campuses are no longer hotbeds of beowulf battles, dissension and civil disobedience, but now they congregate social work en masse like never before. It is lexicography definition now, as it has always been, about young people trying to find meaning in beowulf battles this world. In October of 1967, King was back, speaking to students at Barratt Middle School in South Philadelphia , just six months before a sniper#8217;s bullet left him dead in Memphis. Definition? #8220;If it falls your lot to be a street sweeper, sweep streets like Michelangelo painted pictures,#8221; King said. #8220;Sweep streets so well that all the hosts of Virus Essay, heaven and lexicography, earth will have to pause and say, #8216;Here lived a great street sweeper who swept his job well.#8221; It#8217;s silly to condemn a generation. Human Resource? I#8217;m not convinced that those my age have missed their calling already, that my peers and I will be remembered for not having swept what needs to be swept.
Energy isn#8217;t lost, maybe diverted, but, even still, such complaints sound like hollow shouts at the moon for not being full. The man with the thin goatee likes that one, he says. It#8217;s something he#8217;d expect from lexicography one of his contemporaries, said back when indifference was un-cool, the and Evolution AIDS Virus Essay, world was pocket-sized and lexicography definition, everybody cared. Beowulf Battles? Don#8217;t hear things like that anymore. The Next Generation; College After Its Golden Years. When my mother and lexicography definition, grandmother came to visit me at UC Santa Cruz this spring, I expected them to feel as any parent and grandparent should on a college campus: out of place, uncomfortable, quaintly bewildered. But I was the bewildered one when my mother stood watching the courtyard in front of my freshman apartment, and saw something as familiar to her as it had become to me in the last year.
Three nineteen year old males, with long limp hair and slouching lean bodies to Opportunistic Essay, match, were tossing a Frisbee in lexicography definition lazy arcs. Two were shirtless; the third wore a tie-dyed Grateful Dead t-shirt. Three generations of women stood to the side, observing. Before I got too embarrassed and herded my ancestors away, my mother turned to hers and asked, #8220;Mom, doesn#8217;t this remind you of the Goodman, seventies?#8221; She nodded emphatically, adding #8220;Mhhmm. You#8217;re right.#8221;
In many ways, Kresge, the small college that I attended within UC Santa Cruz, resembles what I imagine to be the college experiences that my and many of my peers#8217; parents had, the lexicography, experience Rick Perlstein describes in #8220;What#8217;s the Matter With College?#8221;, his essay about the changing role that universities play in America. Perlstein would be surprised by Kresge, which superficially looks like a microcosmic time warp. Perlstein#8217;s and the Baby Boomers#8217; nostalgia for a lost era also stirs young people when we revel in the social, artistic, and cultural landmarks of the late 1960s and 1970s. But maybe for us it#8217;s not quite nostalgia, but jealousy, or frustration, grabbing for little, a past we never had. There#8217;s a feeling that our parents were the lucky ones. That they came of age in a narrow and magical window of time, when anything was possible and lexicography, changing politics was sexy, risky, fun. Historically, each generation has at least believed themselves to be cooler than their parents before them. Something big must be going on, or perhaps is not going on, in of sports would that order to convince people at the height of their coolness to forfeit their blase sophistication and embrace their parents#8217; culture. If today#8217;s college students imitate their parents at their age it#8217;s because college used to mean something different, something momentous and liberating. The vast impression that college makes on the individual was reflected in the way that college students influenced the culture, politics, and consciousness of a nation. During the late 1960s and lexicography definition, early 1970s the a symbolic-interaction that, Baby Boomers were at the apex of their power and lexicography definition, rebellion.
They united politically against the Vietnam War and culturally against the homogenization of the 1950s, the and Evolution Essay, decade which gave them life. College was a place to definition, congregate, to share new ideas about sex and politics and music and put them into practice. The basic equation hasn#8217;t changed, and college remains a melting pot blending volatile and HIV Infections, appetizing ingredients. Take a bunch of definition, young adults aching to get away from home, smart enough to beowulf battles, have an idea of what#8217;s wrong with the definition, world and naive enough to have a burning need to change it, add co-ed apartments and man computer, access to lexicography definition, psychedelic drugs and professors who encourage critical thought, and voila! The fabled college experience is AIDS Virus born. But this experience no longer transfixes the nation, as Rick Perlstein notes.
Perlstein#8217;s essay especially struck a chord with me; having grown up in Berkeley, a town whose name is synonymous with 1960s collegiate counterculture and social change, I sometimes can#8217;t fathom that the college campus I#8217;ve strolled through so many times was once the site of the famous Free Speech Movement. The majority of Berkeley students, at least from a #8220;townie#8221; perspective, are benign geniuses. When they come into the restaurant where I work the definition, waitresses look at beowulf battles, each other and roll their eyes; Cal students tip poorly not out of inconsideration or poverty, but out of cluelessness. Lexicography? It#8217;s clear that these people, within a year or two of my age, are accustomed neither to HIV Infections, eating out with friends nor working typical restaurant summer jobs. They#8217;ve been busy the last several years, busy with internships and SAT tutors and community service and whatever else it takes to get into UC Berkeley, whose exclusiveness has skyrocketed since the 1960s and 1970s. They#8217;ve been too busy working the system to even consider dismantling it, as Berkeley alumni once attempted. So it would seem that as schools have gotten harder to get into, and, as certain college advisors say, #8220;a BA is the new high school diploma,#8221; America#8217;s top students, the cream of the crop, have gone soft, have gotten#8230; well, too creamy. Definition? And, as Perlstein#8217;s interviewees mention, many are in school only Opportunistic HIV Infections as a means to definition, achieve the a symbolic-interaction would, next prescribed step, generally grad school.
But this can#8217;t be the case for every college student in America, and certainly not my beloved free thinkers at Kresge. It#8217;s not that we have no cause to lexicography, stand behind, but political protest is more of a bumper sticker whine than a roar when today#8217;s war is so abstract and far away. Something (history?) tells me Kresge#8217;s pacifist population would rise against today#8217;s injustices in fury if only Young Goodman Hawthorne we, like 1970s#8217; college students, were subject to a military draft. But college campus protests and marches wouldn#8217;t be enough. Definition? At UCSC, we march against anything and everything, to Defend Alette, to garner higher wages for the dining hall staff, and other worthwhile causes that require us only to carry a sign and walk half a mile with likeminded friends. A march through the isolated campus makes not a blip on the national or statewide radar, partly because this method has been exhausted in the past and because each protest dilutes the impact of the Strategic Essay, next, in something I can only describe as the lexicography definition, boy who cried protest syndrome (one student even suggested marching for HIV Infections, the right to smoke marijuana on 4/20, ignoring the fact that only definition months prior he willfully signed a UC contract agreeing not to a symbolic-interaction conclude that, partake in alcohol or drug consumption).
Of course, not all campus based political action is so stunted and hypocritical, but this story is analogous of the type college kids take part in today; well-intentioned but often beside the point, and lexicography definition, certainly not making any headlines. College still matters on an individual level, and since the world is comprised of individuals it necessarily matters on a global level, although that may be hard to little man computer, see when contrasted with the impact universities had on politics a few decades ago. College serves as a personal growth tank, a kind of paid vacation that allows for lexicography, creative masturbation and self-discovery. The emotional and intellectual growth of college students is reason enough for me to support the institution that has done so much for me and my friends. Origin Essay? And traditional job training remains a huge factor in lexicography definition why universities matter, because if it weren#8217;t universities we would have no doctors, scientists, or architects. We still need college, although its potential for greater change has been largely untapped in recent years.
But the Opportunistic Essay, function universities once served is lexicography definition not lost; rather, it lies dormant, awaiting a proper catalyst. It scares me to wonder what it will take to mobilize the student population, but I don#8217;t doubt its inevitability. Over the summer, I visited an exhibition at a symbolic-interaction analysis, the Whitney called #8220;Summer of Love: Art of the Psychedelic Era.#8221; As I examined the lexicography definition, various images and artifacts from the little man computer, height of the lexicography definition, counter-culture era, I noticed a familiar mentality of AIDS Essay, rebelliousness, idealism, and experimentation. At the definition, same time, however, the fervent passion and complete abandon which this art represented seemed so remote to the sentiments of my friends and Young Goodman Brown,, colleagues at Columbia University. As Rick Perlstein notes, my generation, like our predecessors, has both an unpopular war and important political concerns, such as homosexual rights, the problems with healthcare, and definition, the crisis in Darfur. Yet, we remain out of the spotlight instead of expressing ourselves and alerting the country to our opinions as the students of the 60s and 70s did. This begs the question: What is a symbolic-interaction analysis that different today? The answer seems two-fold. Firstly, my generation feels no need to act, and definition, this lack of necessity has stifled our activist spirit.
And second, my generation is so concerned with getting a good job that we have become too afraid to Resource Essay, really explore and experiment. The loss of our activist spirit and the opportunity to explore has created a diluted form of college. The lack of passion with which college students today express their beliefs on lexicography definition political issues, such as the war in Iraq or Darfur, can be attributed to the fact that my generation has no necessity to take action and have our voices heard. With the draft looming overhead, a college student in a symbolic-interaction analysis would conclude 1967 knew that if he did not do his all to fight against an absurd war in lexicography a far-away place, then he, or his brother, or his best friend could be sent to die in the jungles of Vietnam. It didn#8217;t matter if you were arrested or beaten at a rally; prospective career opportunities that could be jeopardized seemed meaningless in the face of possible conscription.
Students needed to stop the draftand the waras soon as possible in order to save themselves and their friends. The motivating power of Opportunistic Essay, this urgent necessity can be seen not only in definition the riots and Essay, storming of definition, buildings, but also in how it caused students from across the political spectrum to unite in opposition. On February 5, 1967, for example, Neil Sheehan reported for the New York Times that #8220;leaders of 15 student organizations representing both political extremes as well as the Essay, center#8221; gathered in Washington and overcame their #8220;widely divergent political views#8221; in order to arrive #8220;at common opposition to the draft.#8221; Because there was this sense of lexicography, urgency, students understood that they could let neither laws nor disputes over individual issues or semantics stop them from fighting the draft. For to wait for discussions, debates, or elections could have meant being shipped off. Today, however, much of my generation does not feel this same necessity to make our voices heard. Man Computer? Sure, we#8217;ll write articles for our school newspapers. Lexicography Definition? We may even make the extra effort to skip some classes and go to Washington to protest. But you won#8217;t see many of us taking over buildings in order to force our school into divesting from Darfur or rioting outside of political conventions on national television in order to protest the war in Iraq. This inaction is due to the fact that most of us have no close relatives or friends in these places the way that the students of the 60s and 70s did.
Therefore, we are not very motivated to create change because it is Essay not necessary for our personal survival or advancement. Examples of this lack of necessity can be seen throughout Columbia#8217;s campus. Lexicography Definition? When Brittany Brewer, a member of the little, influential Columbia University College Democrats, expressed the Dems position on the War in Iraq, there was no sense of the urgency and necessity in her tone. For, in an op-ed in the Columbia Daily Spectator, Brewer noted that her organization had #8220;careful consideration and debate#8221; before deciding to support Senator Russ Feingold#8217;s Iraq Redeployment Act. Moreover, this lack of urgency translated into inaction when the College Democrats decided against lexicography definition, participating in a strike from classes on little February 15 due to definition, a disagreement over little, the exact language of the demands. Others, including most of definition, my friends and me, were too concerned with classes and by Nathaniel Hawthorne Essay, studying to start yelling in the middle of campus. Unlike the lexicography, students of the beowulf battles, 60s and lexicography, 70s, we felt no urgency to stop the war, and therefore worried more about our studies or specific language and demands.
The other element that has destroyed my generation#8217;s collegiate experience of experimentation and discovery is our need to find a good job. The students of the Young Brown, Hawthorne, 60s and 70s felt no such need to lexicography, find a spot in their parents#8217; societal structure. Rather, the Human Essay, students and young people of those days wanted to flee from the old generation, a feeling represented in the final scene of Mike Nichols#8217;s The Graduate in which Dustin Hoffman#8217;s character runs away from all of his family and friends with his counterpart played by Katherine Ross. Moreover, these students were not just escaping the old society but constructing a new one, a feeling expressed by Bob Dylan in #8220;The Times They Are A-Changing.#8221; For the folksinger warns the older generation that the young people of the definition, 60s and 70s are creating a new world and #8220;to get out of the new one/ If you can#8217;t lend a hand.#8221; My generation, on the other hand, does not feel any desire to Essay, run away or create a new world because we remain deeply focused on finding a good job and place in this society. Since high school, we have been told that we need to take all the definition, APs we can, get good grades and high SAT scores, and Opportunistic HIV Infections Essay, hold prominent positions in clubs in order to get into a good college. For college is the golden ticket to a good job. This bombardment of the ideology of being perfectly professional in lexicography order to get into a good school has results that last long after receiving the acceptance letter. Though we have gotten into college, we are too cautious of breaking the rules in order to experiment, too concerned with good grades to discover our passions in Strategic Management interesting classes, and too focused on the future to lexicography definition, step outside our normal bounds. A Symbolic-interaction Of Sports Conclude That? Unlike the students of the 60s and definition, 70s, we do not have those four years to be completely free and alienated from little man computer society. We do not get to lexicography definition, explore and experiment. Opportunistic? Instead, we remain locked in the professional world of our parents and remain focused on getting a good spot in it.
In forty years, I will look back on definition my college experience and remember an amazing period of my life. College today remains liberating and exciting. Yet, because my generation feels no necessity to act and because we are too concerned about getting a good job, I will not remember college as a time when I changed the world through political activism or got to beowulf battles, explore who I am and the world around me. Instead, I will remember a diluted form of college. Lexicography? Another Brick in the Ivy-Covered Wall (And Proud of It) One night last spring, in a nightclub outside of Kharkov, techno music blared, strobe lights flashed, blonde Eastern European women lither than I can ever hope to be gyrated. Around 1:30, the DJ cranked up the opening chords of Pink Floyd#8217;s 1979 classic, #8220;Another Brick in the Wall.#8221; My friends and I, visiting Ukraine as part of a fellowship program for little, Jewish college students, were ecstatic.
As we sang along with Roger Waters#8217; most famous line (#8220;We don#8217;t need no education #8220;) my friend Aviva suddenly began jumping up and down, hand above her head in that fake-defiant pop-punk gesture popularized by Good Charlotte and other middle-school-friendly rock bands. #8220;Yeah!#8221; she shouted. Lexicography Definition? #8220;We go to school!#8221; For me, there#8217;s no single moment that captures today#8217;s American college experience better than that, and not just because our best partying songs were all written before we were born, although Journey#8217;s #8220;Don#8217;t Stop Believin'#8221; does get an would conclude that, absurd amount of airtime at campus parties. It#8217;s the whole idea behind Aviva#8217;s shout: we love the idea of being outsiders, but, especially at elite private universities, we#8217;re certified insiders, and lexicography, that#8217;s the way we like it. We want to think of ourselves as independent, ironic rebels, but we still want to kick ass on the MCATs, LSATs, and GREs. We wish we had the guts to blow off our classes to protest the war, but we know that if we do, someone else will snag that coveted A in the Statistics class that#8217;s graded on Human Resource Management Essay a curve, and lexicography, we#8217;re not going to risk it. A few days after my return flight from Kiev landed at Dulles, I was back in the office of Georgetown#8217;s mostly liberal, supposedly alternative newsmagazine, the Voice. Alternative, though, mostly just means that we take pride in publishing snarky reviews of pretentious indie rock bands no else cares about. Of course, our not-so-dirty secret is that, just like our more mainstream and admittedly more popular campus competitor, the Hoya, we get our funding from the campus media board. We think that by acknowledging our status as poseurs, we#8217;re somehow coming out ahead of the beowulf battles, more earnest sellouts. Two years ago, our t-shirt slogan for the annual Voice/Hoya softball game was #8220;Biting the hand that feeds us since 1969.#8221; (For the record, we slaughtered them.) As Kyle Smith wrote in Love Monkey, #8220;Our grandfathers won World War II; we can#8217;t even tie a tie.#8221; It#8217;s tempting to agree with his sentiment, to self-deprecatingly assume that a generation ago people risked their grade-point averages and their future careers to protest the Vietnam War or publish an anti-administration newspaper by hand, while today I can#8217;t even drag myself from Georgetown down to the White House for an Iraq protest, and definition, the most commonly quoted source in my news stories is the school#8217;s Office of Communications. But disaffected dissidence isn#8217;t the defining element of college culture, and college today doesn#8217;t have to Opportunistic HIV Infections, be the same as college a generation ago in order to matter to college students and to definition, the country as a whole. In fact, it can#8217;t.
Today, student activism of the traditional sort is mostly met with skepticism, not only from adults but also from peers. Origin And Evolution AIDS Essay? My boyfriend and lexicography, I have spent countless cafeteria meals arguing over whether the green-bracelet-wearing anti-genocide activists clustered outside the and Evolution of the Virus Essay, dining hall are actually worried about saving Darfur, or if they#8217;re just trying to feel good about themselves while padding their resumes for law school. Definition? For the record, he#8217;s the idealistic government major who thinks the STAND (that#8217;s Students Taking Action Now: Darfur, for anyone who#8217;s not in college) kids actually care, and I#8217;m the premed cynic who thinks their motives might be a little less than genuine. Maybe it#8217;s just my own self-preservation instincts, but despite the benign hypocrisy that runs rampant on little college campuses, I refuse to be convinced that college today is inherently more infantilizing or trivial than it was 30 years ago. We still find ways to make our four years meaningful, if only because no one wants to have the lexicography, Activities section of his or her Facebook profile left blank.
Of course there are cocky Capitol Hill interns who are doing it more for professional gain and a free Metro card than personal growth, but I#8217;m still impressed by how many of my friends spend hours every week doing things they actually care about, without bothering to brag about little man computer, all the time they invest. My roommate since freshman year coordinates a tutoring program for underprivileged middle school students, and another one of definition, my housemates choreographs and dances in the university#8217;s dance company. And then there#8217;s me: reporting and editing for the Voice, helping with developmental psychology research in a campus lab, steaming cappuccino foam at the student-run coffee shop. I know enough to be insulted by the Organization Kid moniker, even though it could probably be applied to me. Man Computer? The difference, I think, is that my friends and definition, I are actually experiencing college, instead of using it as a steppingstone while we plan our next moves. And even if we are drastically self-absorbed, cynical, and status-driven, then our parents have done nothing to disabuse us of the misconception that we#8217;re at a peculiarly important stage that will stay with us for the rest of our lives. The college experience, or at least the idea of it, still matters to American adults, too. Strategic Human Resource Management? Why else would the Education Life section in lexicography definition this very newspaper still print endless articles about the comparative value of degrees and analysis would that, how to seal the admissions deal? (By the way, college students are far more adept at lexicography, understanding the status games that accompany the application process than reporters are: Northwestern and Cornell may have higher acceptance rates or lower SAT scores than WashU and Tufts, but the a symbolic-interaction of sports conclude, former two are still solid status symbols, not consolation prizes for second-tier strivers like the lexicography definition, latter pair are). Management Essay? When it comes down to it, the educational part of going to college probably hasn#8217;t changed that much from the glory (glorified?) days of the #8217;60s and #8217;70s. The experience of getting a multidisciplinary undergraduate liberal arts degree is still unique to the United States, and envied by college students abroad who have to choose their careers right after high school.
I remember mentioning to my dad last spring that I was working on a paper about Fear and Trembling, and detecting the tinge of academic jealousy in his voice when he talked about lexicography, how he never really got to little man computer, read philosophy because his Israeli B.S. in engineering didn#8217;t include any humanities or social science courses. My freshman year, I read Plato#8217;s Republic and memorized the mitosis and meiosis cycles of cell division, like so many other first-year college students in the history of American higher education. Lexicography? To me, that continuity of learning is little one small but crucial reason why college still matters. Definition? After all the games and gossip, I like to beowulf battles, think that we#8217;re still really here to learn a few things. Yeah, we go to school. Not that a caveat would have helped any, but having the seat of my soul kicked over while my brain and heart were impounded all of lexicography, freshman year might have been an Origin and Evolution of the Virus Essay, easier ordeal if someone had told me, for example, to pack a stuffed animal. In a suburb of lexicography, Cleveland, OH, I was quintessentially successful, with friends, grades, and activities. I had read about myself repeatedly in articles parsing the college admissions process for top candidates, but managed to bypass most of the hullabaloo by getting into the Williams College class of 2010 early.
My guidance counselor told me I was a #8220;slam dunk#8221;, and Origin and Evolution Virus Essay, as a response, I did something I used to lexicography definition, do a lot: I beamed. As far as I was concerned, I could do anything, and by letting me in, Williams had confirmed it. As a person as annoying and smug as myself probably deserved, things changed. More than a year after being accepted to Williams College, I was prostrate before it. It was not for not trying that I failed to pass out of grammar-level Spanish, was at the bottom of at least two of my classes, and wrote astonishingly vapid English papers.
Several cleverly named a cappella groups and the choir did not want me to sing with them. With the one group that had accepted me the editorial board of the school newspaper the twenty-five hours I spent working each week were, I was sure, killing me. In short, college failed to confirm most of the retrospectively shallow things I. thought I knew about myself: that I was smart, capable, and categorically worthy of Management, everything I wanted. For the students of yesteryear, college broke the spell of lexicography definition, suburban drudgery and mom#8217;s meatloaf. HIV Infections? College today isn#8217;t like that, I totally agree, because we grew up almost bored by overexposure. Eighth graders smoking marijuana is average rather than abominable, homecoming dances could be made into soft-core porn, and our parents know we drink because they#8217;re the ones popping the corks. Definition? Even our cultural choices might just be indiscretion: a trip to the movies could be to Hairspray just as well as it could be to Paris Je T#8217;aime, and our favorite music is the tinny screams of Kelly Clarkson as well as the strange snaps and Young Essay, claps of lexicography, The Books. A Symbolic-interaction Of Sports Would That? We#8217;re all hybrid drunk and slutty beatnik-fluffmongers, and we don#8217;t need college to show us the wares of the lexicography, world. Nonetheless, college today is not some hornet#8217;s nest of Management Essay, futility. Just like it did forty years ago, college gives us what we need.
And in our case, it#8217;s a huge slap in lexicography definition the face. This past year at school, I became a broken version of myself because, for the first time in my life, I could taste my own inability at something other than the obstacle course in gym class. I had built up a self-perception based on successes, and now, though Williams College did not mitigate my previous achievements, it did demonstrate their obsolescence. Not everyone, of course, enters college with thirteen years of grammar-school affirmation notched into their belt, but that isn#8217;t to say that there isn#8217;t a lot to AIDS Essay, be discovered for definition, any child who grew up with the Internet as a playmate. Everybody is hyped up on culture, liberation, and possibility, and we all think that not only can we do anything but that we will do everything. At college we begin the Origin and Evolution of the AIDS Essay, painful and lexicography definition, satisfying process of beowulf battles, realizing that, much as we may be beatnik-fluffmongers, in most ways, we cannot do and definition, be everything.. There are actually many things that we are not, and a symbolic-interaction analysis of sports would, many things that we cannot do. Not only do you major in only one (or two, or three) things, but there are hundreds of thousands of definition, people who are better at whatever you were your high school#8217;s star in.
Not only are you not the smartest person around, you#8217;re also not the funniest or weirdest or loudest or most sincere or most naked.. Opportunistic? It#8217;s likely that there are even people who share the exact same name as yours. Basically, you#8217;re not special, and you can#8217;t do everything. You and Mr. Rogers were wrong. And yet, you will be absolutely fine. College mattered, I knew almost immediately, because I became as uncertain with how to definition, proceed as I had been sure that I was ready for everything. And, surprise of surprises, though not entirely unscathed, I remained completely functional. Happy, even.
Certainly, a lot of the effects that resulted from Strategic Resource Management my freshman year of college could have come from some other kind of definition, milestone, earlier or later: a new job, a new high school, a death, a birth. But college is distinct because it afforded me and condemned me with the Opportunistic HIV Infections Essay, ability to talk about the confusion, endlessly. Lexicography Definition? The friends I made were a relief and a beacon through the confusion, but they were also great accessories to it. The infirmity of beowulf battles, self-discovery (or un-discovery) via college was increased exponentially by the presence of college pressing up against me no matter where I went. My every failure and pleasure became real and unwieldy only definition when I heard it reflected in the thoughts of man computer, my friends and lexicography definition, confidants in class, waiting in line for dinner, at the coffee bar, in our carrels at Opportunistic, the library, in our beds. As we watched our laundry tumble fretfully in lexicography definition the dryer, my neighbor and I shared our frustrations with our inability to understand our other floormates, who would duct-tape 40 oz. bottles of malt liquor beer to their hands until they consumed the contents. At 4 a.m. my co-news editor and I would peer at each other over our computers and Opportunistic HIV Infections, cups of tea and coffee as we measured picas and scrunched text onto our newsprint pages to lexicography definition, exchange a moment of disbelief, horror and contentment at our present state.
I cried sheepishly into HIV Infections, an unsuspecting friend#8217;s chest when I encountered him after turning in another late and lexicography, incomplete computer science lab at midnight, barely able to articulate through my snot my self-disgust. In the library stairwell, I revealed to and was commiserated by Opportunistic HIV Infections a friend my pettiness as I childishly moaned that I used to lexicography, be #8220;good at stuff.#8221; What I have found at college is crippling uncertainty and self-awareness. All that has come out of my mouth has been, repeatedly, the insidious combination of the three words #8220;I don#8217;t know.#8221; Any logic or order that I once relied upon has vaporized, and I am left trying to explain the dust on Opportunistic Essay my fingers.. My most desperate questions are never likely to be answered, and the sensation of being lost has burrowed itself deep in the valves of lexicography definition, my heart. Instead of turning life on its head, college decapitates it for one, four-year moment. But because we are all running around with our heads cut off, I have learned what it is to of the Virus Essay, need to hold someone#8217;s hand.
The gathering of protestors at the base of Bascom Hill, the iconic center of the lexicography definition, University of Wisconsin campus, featured a carnival atmosphere on the morning of October 18, 1967. An Uncle Sam on Opportunistic HIV Infections stilts teetered above the crowd, another activist impersonated President Johnson and the San Francisco Mime Troupe appeared in lexicography definition whiteface as the Guerrilla Marching Band. Opportunistic HIV Infections Essay? Activists banged tambourines while students assembled to stage an obstructive sit-in at the building where recruiters from Dow Chemical Company, the military#8217;s supplier of napalm, were conducting placement interviews, as David Maraniss described the scene in They Marched Into Sunlight. The crowd of lexicography definition, protestors had grown to well over a thousand by noon, and little, around 1:30 p.m., police forced their way in to clear the building. What happened next shocked the city and eventually the nation, as the churning mass of lexicography definition, students inside the building fell like grain under the scything of Strategic Human Resource Essay, police batons. Forty-seven students w ere treated at the university medical center that day, and many more left with eyes reddened by tear gas, released for the first time ever on definition the campus. Of The? Madison soon became known as one of the most anti-war campuses in America, considered by some to be the Berkeley of the Midwest. Madison saw protests again at the start of the build-up to lexicography definition, the Iraq War, but nothing that could match the Vietnam protests for violence or cultural significance. In this, the campus serves as a microcosm for the nation#8217;s universities as a whole, a barometer of activism that has fallen over time.
And as the status of the analysis of sports conclude, American campus has descended to lexicography, a tepid lull, the attention of the AIDS Essay, American public has waned. There are no more headlines about student protests. The nation no longer knows or cares what happens on definition these serene islands of academia, even though someday these students will be solving the problems created by a leadership that came of age in Vietnam. Former Wisconsin administrator Paul Ginsberg, who watched both the Vietnam and Iraq antiwar movements unfold, found that the Iraq protests were marked by a certain placidness that barely disturbed the quiet serenity that reigned over Young Brown, by Nathaniel Hawthorne, campus. The result was classic pothole theory, a catchphrase harkening back to lexicography, the Vietnam era: Nobody goes to Origin and Evolution Virus, harangue the city council until a pothole appears on their street. In short, nobody#8217;s paying attention to college students because they#8217;re not causing any fuss. Generally, universities weren#8217;t seen as being significant in the Iraq War paradigm, Ginsberg explained.
Nothing was coming out lexicography definition of the campuses. The sacrifice-everything spirit of political speech embodied by the #8217;60s is dead. Like the LBJ impersonator at the Dow protest, another imitation president made the rounds in Madison during Bush#8217;s re-inauguration, but the majority of Strategic Human Resource, passersby paid hardly any attention to the Bush puppet, according to the Capital Times account. Many occupied themselves with avoiding snowbanks, and Others #8212; especially in the campus area #8212; were talking on cell phones, the paper recounted. As my friend Eli Lewien, chairman of the Madison College Democrats, can attest, it is extremely difficult to mobilize students unless you find issues they#8217;re passionate about and that affect them directly. This is why our generation will never be able to match the definition, Vietnam generation for activism. In the late #8217;60s, the reality of the draft was crushing; every male student had a stake in Goodman Brown, Hawthorne the war. Every faculty member had a stake through grading, since flunking out meant not just an ignominious return to your parents#8217; house, but rather a possible posting to Lai Khe. Another factor to account for lexicography definition, students#8217; lack of beowulf battles, piss and vinegar in Madison is the new dynamics of lexicography definition, peace activism. Police handle protests far more gingerly, and the events are, like everything else in this world, increasingly more globalized, with students taking bus trips to Origin of the AIDS Essay, Washington, D.C. to protest.
Ginsberg scoffed at these mass marches, calling them feel-good protests with no direct impact. But in an era when the nation no longer pays attention to students, sometimes we must leave the island to be heard. The real reason college students didn#8217;t lead the definition, nation on Iraq, however, is because the nation has sped up. With Iraq, the evidence for disaster has not been coming from Strategic Resource angry young people, but from activists who first became active during Vietnam and lexicography, attached a stigma to Essay, the war from the start, explained sociology professor Joseph Elder, who witnessed the #8217;60s on campus as a faculty member. Although it is true the college experience has lost much since those heady days, it is simply folly for our generation to definition, attempt to define ourselves through the modus operandi of another era. Our legacy will be found elsewhere.
My friend and Opportunistic Essay, professor Katy Culver, who has been teaching journalism at Wisconsin since 1990, is convinced today#8217;s students have something to definition, offer the Vietnam generation didn#8217;t: a multi-tasking of thinking learned through the incorporation of Internet-era technology into our lifestyles. Indeed, I remember learning to instant message in high school; my burgeoning interest in social matters prompted me to develop the multi-tasking finesse to a symbolic-interaction analysis of sports would conclude that, carry on a dozen conversations at a time. Lexicography? This mindset can trump what Culver described as the cookie-cutter mentality of the Baby-Boomer generation in openness to new ideas. The current generation is much more willing to look at Strategic Essay, an array of choices and consequences than the boomer generation, Culver explained. I see our future legacy as something akin to definition, the book that made me realize the futility of the U.S. occupation of Iraq: Wisconsin alum Anthony Shadid#8217;s Night Draws Near, the Iraqi people#8217;s account the freedom from Essay Saddam and oppression of fear we brought the country. My generation will someday be able to act on such a nuanced view of the situation, I hope. College serves to form our multi-task thinking ability. Lexicography Definition? Students may no longer draw the inquisitive eye of a nation in turmoil, but the education we receive remains critical. In the Vietnam era, that education was found as much on the tumultuous campus as in the classroom. That#8217;s no longer the case but in the Madison classroom today, more students are learning Arabic than ever learned Vietnamese, Elder said, and enrollment in courses on Islam is up.
At the time of the Dow protest, the university offered four study abroad programs, he said. Now it offers over 150. Man Computer? The new generation realizes Americans are too Euro-centered and need to know more about the world we#8217;re living in, he maintained. The idea is to study and do some good for shitty countries, was the matter-of-fact explanation given by my friend Ben Pasquale, who persevered through a year of Arabic even as a quarter of his class dropped the course. Most of his classmates share this ideology, he said. Some will eventually amass the linguistic ability and cultural understanding to begin to lexicography, bridge the widening Mideast-West gap the Human Resource, Iraq War has fostered. Their new brand of lexicography, knowledge doesn#8217;t make for a good news clip, but it will have more of an impact. At least, that#8217;s the benefit of the doubt I give the college experience today, since the Opportunistic Essay, rose-tinged past invites nostalgia, whereas the definition, unknown future only invites only cynicism. Beowulf Battles? College is a game.
It#8217;s a cutthroat four-year competition to the finish line. Lexicography? How do you know when you#8217;ve won? I guess when you get that seven-figure job offer that you#8217;d always hoped for. But like every game, there are rules and little, strategies. Rule 1: Don#8217;t do anything stupid that employers won#8217;t like, such as fail a class, get arrested, or join the lexicography, ACLU. Rule 2: Make yourself stand out to interviewers by doing more pointless crap than the next guy. Rule 3: Don#8217;t waste your time with anything that involves emotion or creativity. That stuff is for wimps and won#8217;t get you hired. The college game, as everyone knows, starts way before your first drunken hook-up, way before your roommate-from-hell#8217;s flatulence, and way, way before everything you thought you knew how to analysis would, put together from Ikea starts to fall apart. For some unfortunate individuals, the college game started back when their parents pulled every string imaginable to get them into the very best private kindergarten around.
Most kids today, though, started the college game when they joined debate club, ran for president of honor society, founded an awareness organization, or tried out for definition, captain of the tennis team, just so they would gain an extra edge when their application came before the acceptance committee. Strategic Management? And all that while cramming for lexicography definition, the most infamous three letters in Young Brown, Hawthorne any high schooler#8217;s vocabulary: SAT. Just getting into college has gotten so competitive that parents are now willing to pay over $500 per one-hour session for SAT tutoring. (You read that right). You don#8217;t have to lexicography definition, get an little, 800 on the math section to realize that for all that, plus $40,000 in tuition money every year, plus a mountain of student loan debt, parents and students insist on something more tangible than just four years of lexicography definition, fun and a diploma they want a solid job waiting for them. There was once a time when college wasn#8217;t a competition. This was a time when college campuses were noisy and dissident, when old musky halls of learning were filled with radical, new, earth-shattering thoughts, when college was the place where ideas had the Goodman, power to change the world and did. On the popular animated satire Family Guy, a show which every college age American should be familiar with, the archetypal baby-boomer matriarch, Lois, once exclaimed coolly, #8220;My days in college were so exciting.
This one time, the National Guard came and shot some of my friends.#8221; But since those days of yore, America#8217;s once noisy and dissident college campuses have been reduced to quiet and complacent conformity, because that#8217;s what gets you A#8217;s and gets you hired. #8220;What did you do last summer,#8221; an lexicography definition, employer might ask a college applicant. #8220;Oh, I spent most of it on Goodman by Nathaniel Essay the road with my friend Dean Moriarty driving across America, rebelling against orthodoxy, and discovering what life means.#8221; There was once a time when that answer might have been commonplace, perhaps even respectable. But times have changed. Today there are few arguments, few protests, and lexicography definition, little dissension. Have students grown more complacent or merely less argumentative? For one, the distinction between adult and college cultures has waned considerably, mostly due to modern technology.
If it weren#8217;t for beer pong (a campus mainstay), adults today would seem quite a lot like slower, more wrinkled versions of analysis of sports conclude, their progeny. Argument is simply no longer a part of campus life (it#8217;s been relegated strictly to definition, internet forums). When every niche interest, as strange as they may seem, has its own website, the need to Young Brown,, shout out for acceptance seems unreasonable. With stores like Urban Outfitters, even rebellion has been commercialized. Lexicography Definition? Oh, and what about that prevalent sense of alienation kids felt a generation ago? That#8217;s not a problem which blogging about won#8217;t cure. (But be careful. If you say anything that might be construed as neo-Marxist, don#8217;t use your real name employers will find out! Don#8217;t post pictures of you having to beowulf battles, much fun either employers might realize you#8217;re actually a person). Definition? Thanks to cutthroat competition, pushy parents, and the possibility of Origin and Evolution AIDS Essay, making more money quicker than anyone 40 years ago could have dreamed, kids are growing up to become callow adults faster than at any other time in American history. When you see a despondent 18-year-old in lexicography definition a suit and tie rushing with coffee for his overbearing supervisor instead of would conclude, vivaciously exploring the Peruvian wilderness, just ask yourself, #8220;Where did childhood go?#8221; My brother, who is lexicography definition a junior-partner at a hedge fund in Human Essay Manhattan, once bought me a t-shirt that said, #8220;I Have a Degree in Liberal Arts. Would You Like Fries With That?#8221; As funny, and as irritating, as that gift was, it exemplifies a pervasive truth in lexicography definition America today: there just isn#8217;t much money in human emotion or creativity.
According to CNN, finance majors earn 40% more every year than history majors. As any economist will tell you, people, as it so happens, like money. Which is why it shouldn#8217;t be surprising that business is by far the most popular major in America today. In time though, ideas and emotions will always win over Opportunistic Essay, the material and mundane because ideas are timeless and lexicography definition, objects are transient. Unfortunately, substituting truly rewarding learning for what amounts to mere dollars and cents is robbing American youth, and American culture as a whole, of something very, very valuable: heart. Colleges though, bowing to beowulf battles, demand, are overly preoccupied with teaching kids how to do rather than how to think. Doing pays off, while thinking, it so happens, commands little more than respect. The only lexicography definition problem with this mode of education is that kids become too automated. Like the college game itself, every multiple choice bubble has become merely another cog in a symbolic-interaction analysis of sports would conclude that a vast inorganic machine.
Fortunately, many educators in high schools and colleges have begun to realize this transformation and lexicography definition, its implications. A movement has already started that is phasing out #8220;what#8221; questions in favor of #8220;why#8221; questions, and eschewing multiple-choice tests in favor of and Evolution of the, essays. This is a step in the right direction and a trend which I hope continues. College as a discrete experience is beginning to disappear as it transforms into another rung on the ladder to riches. Lexicography Definition? But that doesn#8217;t mean that the college life has nothing to offer American kids today.
Indeed, college is a symbolic-interaction of sports would a place to interact with new, interesting people from exotic places like Moscow, Mozambique, or Minnesota. Lexicography Definition? Of course college is also where we learn to live on our own, fend for ourselves, and a symbolic-interaction of sports that, cook lots and lexicography definition, lots of pasta. Outside of the library, college teaches us invaluable lessons in who we are, where we are going, and what we are capable of a symbolic-interaction of sports would, accomplishing. We also might learn a thing or two about the French Revolution on the way. The real problem with college is definition that for far too many students and parents it#8217;s not about college: it#8217;s about after college. John Lennon said, #8220;Life is what happens when you#8217;re busy making other plans.#8221; College students, and the parents who push them to success, need to little man computer, realize that life is happening right now, all around us, everyday. Don#8217;t let it pass you by. Lexicography Definition? The summer before I entered the Origin AIDS Virus Essay, 10th grade, I attended a week long program on the entertainment industry in California. There were many speakers who had built up impressive careers, but only one made a real impression on me. He was a movie producer who said #8220;college ruins your creativity.#8221; Some of my fellow attendees were shocked by his ideology.
When I relayed this to my mother, her response was #8220;So go to lexicography, college and stuff your ears with cotton.#8221; My mother had a valid point. College has become a necessity. It has become what high school was to earlier generations. This nation has become obsessed with the analysis that, college experience. Thanks to guidance counselors and parents, it has become a cottage industry for standardized test prep companies, irrelevant special issues of newsweeklies and department stores who purposely order an abundance of iPod accessories to hawk in definition the months of July and August. Parents are sublimely interested in the upward mobility for their children, which seems to be guaranteed by a printed slip once their checks clear after roughly four years. HIV Infections? Yes, college as experienced by those of the baby boom era has come to lexicography definition, an end.
And as one who went off to college reared on some of the stories of that era, all that I can say is that it#8217;s too bad. I cannot imagine anything more exciting then a time to come of age in discussion with your peers, a time to explore and have a political, social, and creative awakening. With the beowulf battles, advent of the personal computer, people would rather obsessively collect new information on their peers through social networking websites rather than get to lexicography definition, know them over pizza and discussions in the dorm lounge. When you enter college now, you#8217;re almost fully formed: you have been forced to a symbolic-interaction would conclude that, focus and definition, know where you are going before you even get there. Most kids have accomplished more before they get to little man computer, college than any other generation that preceded them. Definition? The question that really needs to be asked is this though: how much of what happens at college is Essay a mirror of the society at the time in lexicography which someone attends?
Prior to Opportunistic, the 1960s, those who attended were called college men and women. During the 60s, it was college kids. Different times, different societies. The college experience of the 60s doesn#8217;t exist anymore, but it did not exist in definition that form before that time. At most schools, college students today put things in Strategic terms of market thinking. Everything today is about branding: this is how people operate in society at large. It is not necessarily what you learned at definition, college that matters; it is little man computer where you went that matters in lexicography the eyes of those that judge. Beowulf Battles? Some students jump off the lexicography definition, conveyer belt and take some time off after college before entering the workforce or going on to graduate school. Unfortunately, not all students have the Young Goodman by Nathaniel, luxury to take time off to find themselves #8212; many of them are faced with the burden of paying back loans. I worry that many of my generation are going to be adults trapped in careers and lexicography, trapped by decisions made as high school kids forced to focus so early on where they are headed without really having had the chance to Strategic Resource, explore other things around them. Had the dot com boom of the late 90s lasted, colleges might have had to reassess the pressure cooker of college admissions.
Some of the brightest students were delaying college admissions to pour themselves into their passion and start businesses and fuel a new industry. Even my sister thought about abandoning a college degree. She asked my parents if they would be willing to funnel the cost of definition, her college education into little man computer, a start up enterprise. Not surprisingly, the response in my family was get the education first and then there could be talk about lexicography definition, secure financing for an enterprise. The dot com boom became a dot com bust before my sister even graduated from Strategic Resource Management Essay college. So is college relevant today? Yes, but only as a means to lexicography definition, an end. For everything gained from Opportunistic attending college, we have lost the creativity that comes with discovery. Lexicography? Though society may not have suffered from this loss yet, it remains to be seen what its effect will be on generations of college students to come. Rick Perlstein#8217;s article #8220;What#8217;s the Matter With College?#8221; reminds me of an earlier NY Times essay entitled #8220;Diversity#8217;s False Solace#8221; by Walter Benn Michaels.
In his essay, Michaels#8217; main thesis is that the beowulf battles, issue of definition, race is a distraction from the much larger issue of Young Goodman, economic inequality. My main thesis is that the definition, issue of #8220;what#8217;s the Origin AIDS Essay, matter with college#8221; is lexicography a distraction from the Hawthorne Essay, much larger issue of #8220;what#8217;s the lexicography definition, matter with America?#8221; Perlstein#8217;s answer to Essay, his question is that: College as America used to understand it is coming to an end; which can be paralleled to the much larger problem that I am suggesting: America as America used to understand it is coming to an end. Lexicography? Perlstein concludes in his final paragraph: Why aren#8217;t people paying attention to the campuses? Because, as a discrete experience, #8220;college#8221; has begun to disappear. He is Origin of the AIDS perfectly correct in saying that #8220;as a discrete experience, #8216;college#8217; has begun to definition, disappear.#8221; I couldn#8217;t agree with this more. In the early #8217;60s to late #8217;70s, Americans perception of college was significantly different from analysis of sports conclude that how Americans perceive it today. Perlstein describes the earlier American perception of college as #8220;bucolic images of a mystic world apart, where 18-year-olds discover themselves for the first time in a heady atmosphere of lexicography, cultural and intellectual tumult.#8221; Contrasted to today, Americans perception of college is somewhere between Van Wilder, Girls Gone Wild, and American Pie 2. To understand this huge shift in Americans#8217; perceptions on college and man computer, college students, we need look no further than the powers that have the most influence on changing Americans#8217; perceptions The Media. Looking back 40 to 50 years ago, media ownership was quite diverse, with well over 50 different media outlets reporting a diverse range of news. This diversity in news is what brought about the nation#8217;s #8220;obsession#8221; with college and college students. However, if we look at media ownership in definition the present day, diversity in media no longer exists.
The majority of media ownership has been consolidated down to six corporations, and Origin of the AIDS Virus, this is precisely why news today is all the definition, same. Therefore, the diversity in news is a direct consequence of of sports would conclude, diversity in lexicography media ownership. Without diversity in media ownership, there is no diversity in man computer news. Lexicography? Furthermore, concentration of media ownership has completely flipped the nation#8217;s obsession 180 degrees. Once a nation obsessed with an institution of higher education, is now completely obsessed with the complete opposite: money, sex, alcohol, drugs, violence, fashion, celebrities, terrorism, and any form of entertainment. So #8220;why do college and college students no longer lead the culture? Why does student life no longer seem all that important?#8221; As Perlstein states, #8220;the nation was obsessed with college and college students.#8221; It is Opportunistic HIV Infections important to understand that the only reason why college and college students led the lexicography, culture in of sports would conclude that the first place was because of media coverage. Lexicography Definition? The only reason why student life seemed important in little man computer the first place was because of lexicography definition, media coverage. The only reason why Paris Hilton#8217;s sex tape, terrorism, or global warming seem important to us today is beowulf battles because of media coverage. The media has always led the lexicography definition, culture and continues to do so to this very day. Little Man Computer? The diversity in media ownership 50 years ago allowed for diversity in news; college being a part of that diversity.
In comparison, the lack of diversity in media ownership has resulted in where we stand today; a nation completely obsessed with money, sex, celebrities, entertainment, partying, drinking, and everything else in between. For instance, the media#8217;s effect on culture is crystal clear when looking at lexicography, the dramatic change in little popular music. Back in lexicography the early #8217;60s and late #8217;70s, diversified media ownership allowed for much more public dissent, especially through music. The Beatles, especially John Lennon, are perfect examples of this. They took advantage of analysis of sports would that, their increasing media coverage and lexicography, sent messages of love and peace all over the country, and demanding the end of the Vietnam War. With the power of the media coverage, Lennon was able to organize mass demonstrations in America. Naturally, college students were able to Origin of the AIDS Virus, organize and hold demonstrations and protests expressing public dissent.
Intuitively, this should make sense since college campuses are institutions for higher learning, an environment of individuals that understood that the liberties we have today were not a gift, but a result of centuries of struggle. Unfortunately, when reflecting on the popular music of definition, today, we get back to the nation#8217;s initial obsession with money, sex, and entertainment. Popular music today is dominated by mindless bantering about sex, violence, money, drugs, and material possessions. Little Man Computer? I wish I was kidding, but watching an hour of definition, MTV will show you that I#8217;m not. Let#8217;s be realistic here.
The college experience, like almost every other experience in America, has been tainted by money. A college education is no longer treated as an end in itself; but rather as a means to Essay, an end. In other words, education is no longer viewed as an lexicography, inherently good thing in itself, but as a means to getting a job to accumulate wealth and live a #8220;happy#8221; life. So it doesn#8217;t matter if you don#8217;t truly understand the material you learn in all your classes because in the end, your diploma is your ticket into the corporate world. #8220;D for Diploma,#8221; as many college students say now-a-days. The stupefying spiral in the public education system is another significant factor on influencing students#8217; perception of education. From an Goodman Brown, by Nathaniel, early age, kids have been conditioned to dislike school. It is definition no exaggeration to describe an beowulf battles, average American student#8217;s perspective on school as an excruciating pain that doesn#8217;t end until the bell rings at the end of the day signaling everyone to go home. This #8220;school sucks#8221; mentality is lexicography reinforced day after day, year after year, and after 13 years of school (K-12), it is no wonder that this attitude is Strategic Management further transferred to college. Thus, #8220;college as America used to understand it is lexicography coming to an end#8221; because education in America has been coming to an end. (Evident in a symbolic-interaction would that the lack of public funding and lower test scores).
How would I know this? Because I lived it. I was immersed in the American public education system from kindergarten to high school and found myself surrounded by this #8220;school is lexicography not cool#8221; mentality, even all the way through college. We even have words to describe people that view higher education as a good in itself; dork, nerd, geek, bookworm, etc. To conclude abruptly, the issue of #8220;what#8217;s the AIDS Virus Essay, matter with college#8221; presents itself as a distraction to a much larger issue of #8220;what#8217;s the lexicography, matter with America.#8221; Unfortunately, this is a fully loaded question that can not be tackled in under just 1200 words. However, to Strategic Human Resource Essay, answer the essay#8217;s question:
Yes, the college experience is less critical to the nation than it was a generation ago, but only because the lack of lexicography definition, funding for Young Brown, Hawthorne Essay, public education and heavy concentration of media ownership has made it so. Large protests and demonstrations have been and continue to happen in the United States and all over the world, but why the lack of media coverage? Demonstrations, drug use, hippies, bands, making a difference in the world, all of these are images that were once synonymies with college. I#8217;m sure that if a person was to quiz an adult on what college was like in lexicography the 60#8217;s and and Evolution of the AIDS Essay, 70#8217;s, they would no doubt be presented with images like this. #8220;We really made a difference back then.#8221; seems to be a reoccurring theme amongst people who graduated in this time era. What is the view of college today though? Is it different? Rick Perlstein seems to believe the view has been altered over lexicography, the years. After all, he clearly states this opinion in his essay What#8217;s the little man computer, Matter with College?
After reading his piece and examining my own experience with people I know who have gone to university, I tend to believe Mr. Perlstein. The college experiences of yester-year seem to be worlds apart from the college experiences of today. Upon taking a closer look though, the experiences aren#8217;t that much different. For example, I will reference the Vietnam War era. Here we have an unfavorable war, and large masses of college students with strong opinions. This parallels the current situation. However, they differ on one central main component. I am of lexicography definition, course talking about the Origin AIDS Essay, availability of the internet. Back in the seventies a student could write up pamphlets and distribute them by hand.
To do so though would require a gathering of definition, people. Today with inventions such as e-mail, facebook, and instant messaging, it makes getting ideas across easier. Not to mention, no people skills are required. The internet is a blessing and a curse. It allows for Strategic Human Resource Management Essay, a much easier exchange of ideas, but there#8217;s no personal interaction. Does that take away from the lexicography definition, overall college experience? This question is not easily answered, but rather brings up another pivotal question. A Symbolic-interaction Of Sports? What is the college experience? We all know that it is different for every person, but clearly there is lexicography definition a difference between our college experience, and that of the flower generation. In essence the college lifestyle has merely adapted to change. If the tools that college students have now were available during the previous years there is no doubt they would have been utilized.
Information may have been spread faster, but would all the demonstrations have been same? Would that fire that was there still have been present? Whereas college is the same in that people go, they learn, they become more mature, they question, it has changed in analysis of sports conclude its role in influencing politics. I believe people go to lexicography definition, school today to better prepare themselves for the real world. Students want to graduate, get into a good job, and make money, lots of it. Back in the day people went to college to learn, but more so for the experience. Young Goodman Brown, By Nathaniel Hawthorne Essay? #8220;Hey we#8217;re going to lexicography definition, learn some stuff, but at the same time why can#8217;t we change the world?#8221; seemed to HIV Infections, be what was really wanted in the 60#8217;s and 70#8217;s. With the political scene not nearly as hotly contested today in college, what is still the same?
Sure we college kids have our music that no one has heard of, and we still have our drugs, only now in smaller pill form, but I believe we also have a greater sense of self-worth. Even though the college major can change substantially over four years, kids nowadays know what they#8217;re in for when graduation day comes around. A majority of students leave college already in the workforce. Back in definition the 60#8217;s and 70#8217;s it is my belief that even though many people became successful, a majority back then really wasn#8217;t prepared for what was going to happen after graduation day. Basically the college of today does parallel the college of our parents. Things are just more readily available for today#8217;s youth. It#8217;s not necessarily a bad thing, but it just makes things a lot different for man computer, us.
No longer do we need to lexicography, leave the dorm room to globally post our ideas that could radically alter the world view, that is of course if people still pay as much attention to college students now as they did in little the 60#8217;s. The college experience is a product of the individual, and that is something that will always stay the definition, same. My days leading up to college were like everyone else#8217;s: soul searching, anxious looks into the future, and SAT prep. First the right school had to be found where a mystical symbiotic bond would be formed. Then humble applications of prostration had to be sent in, pleas to enter through their silver arches into a mythical community. The long wait would follow next, where admission officers, strangers, would decide your future with decidedly meaningful grades and test scores. I had ideas of what it would be like. Pop culture had filled me with Animal Housian notions of old couches on bottle strewn lawns and John Bellucci#8217;s running amok, proud beer bellies leading the way.
But that was only a part of the picture. Intertwined with the idea of the perpetual party my mother had instilled the vision of a place of possibility where my mind would we awakened by wise mages of academia. From a societal lemming I would be transformed into a tiger of free thought. She was the first in her Irish Catholic family to go to college. From being taught by conservative nuns in high school so was flung into the University of Young Goodman by Nathaniel Hawthorne Essay, Massachusetts in definition the swinging 60#8217;s.
From all accounts, hers was the Goodman by Nathaniel Essay, archetypal American college experience. She joined a sorority, dated the president of the fellow fraternity, and even got lost in lexicography definition a flower powered van trying to Opportunistic HIV Infections Essay, drive to lexicography, Woodstock. But what she recounts with the most passion (I still see a gleam in her eye when she tells the Opportunistic HIV Infections, story) is the barrage of new ideas that hit her while away at college. She was shocked and definition, shaken to beowulf battles, the core when everything from the lexicography, church to beowulf battles, the infallible American government was put into question by her professors. She went from old nuns with rulers who taught the rigid role of women to lexicography, bra burning, and she went from having a zealot like faith in her president to partaking in Human Resource Essay radical protests against the Vietnam War. That was my mother#8217;s college experience. Needless to say, I had lofty expectations of what awaited me. What did await me in the fall of 2004 was something else.
The first weeks were exciting; it was a lot like summer camp (meeting loads of new people, settling into a new smaller room) but with a copious amount of beer and drugs. The air did bristle with energy and freedom; it was a new beginning for everyone. Lexicography Definition? I barely recall being crammed into neighbor#8217;s dorm room with twelve others gathered around a tall hookah pipe. The spirit of togetherness and sharing was almost tangible as everyone added to the growing mountain of burning weed. After #8216;frosh week#8217; things cooled down slightly as classes commenced, but my education in funneling beer and hauling on bongs continued. Scholastically, my first year focused heavily on philosophy based on the Oxford tradition. So while my mind was altered from what I drank and smoked, it was hit harder from what I read and listened to in the Strategic Human Resource Essay, large lecture halls.
Every major literary work seemed to captivate me, which led to lexicography definition, a most undesirable inner conflict. Plato, Kant, and Aquinas battled in my head for supremacy, while Dante just made me feel guilty over Strategic Human, skipped classes and last minute papers. He made sure I realized that I was sliding from Paradisio down toward the great chasm in lexicography definition the sea. In the end the existentialists offered a form of salvation. Instead of contributing to the chaotic spin of Opportunistic HIV Infections, my moral compass, they simply broke it, leaving me on definition my own to choose my path. After that I was more attuned to see what was going around me in the college world. Out of the haze of the of the Virus, hangover and smoke I saw what had become of our great bastions of learning. They had become stale tributes to a bygone era. Genuine political activists had been replaced by stoned fans of the Daily Show and definition, real feminists had been replaced by fashionistas.
In fact what I came to see everywhere was a pale replica of what was. It seemed everyone wanted to replicate the Opportunistic HIV Infections Essay, 60#8217;s, and the new age hippie was the result, a privileged middle class wannabe had emerged who wanted to lexicography definition, sit cross-legged and sing Dylan songs and not do much else. It seemed to me the beowulf battles, substance of college had been carved out over time as energy shifted toward only lexicography definition aesthetic preservation. Expectation led the way toward fabrication as we demanded what we were led to expect by our parents and by MTV. We wanted both our Belluccis and romantic revolution. On December 1st, 2004 I went to Halifax, Canada to protest President Bush with six thousand other #8216;activists.#8217; There were clever signs, chants, and a spirit of rebellion. We marched in union on the main street, blocking traffic and altogether having a great time. Bush never did see any of the protesters, being separated off by a symbolic-interaction analysis would conclude that a mile of definition, security, and the march got little press coverage. Beowulf Battles? All in lexicography definition all I was left with an acute sense of Origin, disillusionment from the whole experience. We had done everything right, people had protested the lexicography definition, system with minds full of Strategic Management Essay, conviction and heads full of Rasta dreads, but something was wrong. We wanted to carry the definition, torch of our radical forefathers and foremothers.
We wanted to Origin and Evolution of the AIDS Virus Essay, make a difference, but nothing was accomplished. A hole began to grow inside of lexicography definition, me and I became conscious of the beowulf battles, passion that passed through and out of me. What was the matter? What#8217;s the matter with college? Perhaps it was because in the new millennium the wool had already been removed from our eyes. Kids left High School jaded instead of lexicography definition, na. Strategic Human Management? Faster. Lexicography? Smarter. Better? In one day a student can race across campus from a symbolic-interaction of sports conclude class to class, surf the lexicography definition, #8216;net for the latest in peace talks and pop culture, save the world and the whales at a local non-profit organization, and call a friend back home in the #8216;spare#8217; time left over.
At first, this day sounds productive and enriching but something profound is missing#8230;connection. Despite the varied benefits of technology and a high speed life, the modern wonders of western culture have stolen deep human association from much of Origin of the Virus Essay, college life. It started with the cell phone. Small, unimposing, even cute. With it, long-distance correspondence was novel again. Soon, however, late appointments were easily rescheduled with a simple dial, angry phone calls were less intrusive, and we excluded ourselves from each other in exchange for lexicography, those far away. While I personally would not trade the ease of a symbolic-interaction analysis, calling my mother with any concern or excitement, I have seen how excessive cell phone use is disrupting the college atmosphere. At spontaneous gatherings of intellectual discussion or pure frivolity, an involved participant is distant the definition, second the phone rings whether or not he answers it.
A professor and beowulf battles, her students are distracted from intense conversations of human nature and the perplexities of culture by the subtle vibrate of a phone. Being in touch with the world 24/7 has ironically cut us off from the lexicography, present moment imbued with learning potential. Likewise, the current trend of Goodman Brown, Hawthorne Essay, portable music has removed college students from the present. Reflection and deep thoughts are stifled by the constant feeding tube of noise the ears of youth seem to lexicography definition, depend on HIV Infections for nourishment.. Moments of silence permeated only by the wind and lexicography definition, occasional bird trills have been usurped by plastic headphones that filter out the natural world and Strategic Resource Essay, pipe in the artificial beats and rhythm of man. Definition? Music criticism on campus is less about classes concerning opera and the innovations of Schonberg and Opportunistic, Strauss. Instead, it is students comparing and pirating their playlists, critiquing musical tastes of their friends rather than the masterful compositions of composers past. Granted, there have been times when music has caused me to think, ponder, and create, but oft times it is an escape from stress or boredom. Stealing the quiet inherent in time spoils the inquiring mind by letting it turn off rather than utilizing these moments for mulling over the philosophical and ethical conundrums proposed in lecture or the possible political and historical reasons behind current events. The double edged sword of the definition, Internet is Opportunistic HIV Infections Essay arguably a time-waster but those who laud its benefits are also in lexicography definition the wrong. Young Brown, By Nathaniel Hawthorne? It seems that having knowledge literally #8216;at our fingertips#8217; would spawn swarms of overnight geniuses, yet they are markedly absent from campus life.
Complacency, it seems, has intervened. Lexicography Definition? Lighting speed facts are demanded, we expect no less. But losing the of sports would conclude, hard work of searching for knowledge and understanding causes us to definition, take the waterfalls of potential leaning with a small cup rather than by the bucket fulls. Human Resource Management Essay? Everyone can know the precursors and outcomes of the Revolutionary War or the reactions of the Krebs cycle, so why really learn, why really understand if it can be looked up in an instant? Even more so when many teachers have become mere managers of online courses; responsible for releasing the torrent of facts but less accountable for instilling excitement and the thirst of inquiry. The skill of definition, synthesizing all these facts is arduous when every minute detail could be scrutinized and a multitude of opinions exist.
It is almost easier to sit and watch the cascade rather than actively argue, debate, and conclude ones own opinion. Lest this be no more than a diatribe on the ills of technology in a university setting, let me point out that the struggle of balancing electronic artifice with natural thought is a reflection of the analysis would, larger battle between the lexicography, individual and society as a whole. Essay? The towers of technology have become beacons for the individual: customize your academic course list, my consumerism, his to-do list. What about definition, #8216;ours#8217;? The university setting caters to the individual all too often at the expensive of collaboration. High grades are for the one who makes it to the top, group work for the lazy. Resource? The mentality of the masses is regarded as #8216;mob theory#8217; or #8216;blind sheep#8217; rather than recognized for its power of creativity and lexicography definition, brainstorming. A generation raised on the word #8216;unique#8217; has lost faith in HIV Infections the strength of cohesive society.
The regulations of definition, universities can continue to focus on each student by setting up endless programs to aid assimilation into and efficiency in conclude that college life. But by lexicography doing so, we lose the vivacity of productive, albeit sometimes reckless, exploration. More stands to be discovered in the spontaneous and innovative gatherings of oddballs and intellectuals-in-training than any choreographed activity that clumps students together through automated questionnaires. The good intents of college counselors to support students socially and academically is unfortunately seen as forceful imposition of #8216;the system#8217; driving students to mind-numbing techno-simulated activities rather than human interaction in order to a symbolic-interaction conclude, avoid doing what the lexicography, rules encourage for their success. College should be a time of discovery no matter how random and Origin AIDS Virus Essay, unlike the picture perfect route to a prosperous career. If administrators take the chance of a little more chaos, students will surprise even ourselves: groups will naturally coagulate and definition, the individual will more readily set aside electronic isolation in exchange for enlivening and stimulating discussion concerned less with movies and music and Brown, by Nathaniel, more with solutions for society. It is time to turn off the switches and turn on our minds. It is time to embrace the quiet to find ourselves and our connections to others in lexicography the here and now.
The Kids are Too All Right The Homogenization of Youth and Opportunistic, the College Experience: A response to Rick Perlstein#8217;s essay #8220;What#8217;s the matter with College#8221; If we were to examine the definition, mechanisms of college today, we would find the framework of these institutions to be startlingly similar to those of a factory. I recently received my undergraduate degree from Eugene Lang, the Opportunistic HIV Infections, undergraduate Liberal Arts division of New School University. The New School University is an appropriate place to examine the streamlining of the #8220;college experience#8221;. My mother#8217;s college experience took place during the definition, golden age of campus activism, the 1960#8217;s. Regardless, she finished her undergraduate degree in Young Brown, less than three years, for she did not have the time or financial opportunities to enjoy the lexicography definition, frontier of analysis of sports conclude, American lifestyles as reminisced in Rick Perlstein#8217;s essay. Her only #8220;radical#8221; act was wearing jeans to school.. Yet, when it came time for lexicography definition, her son to Opportunistic HIV Infections Essay, start applying to college, she was awash in nostalgia.
For my mother, who didn#8217;t have the privilege to live on a college campus or take part in any extra-curricular activities, a reminder of these years still exuded a sense of nervous excitement. Herein lies the defining characteristic of my generation: there is no more excitement, because there is no more danger in the college experience; no more lust for danger. By #8220;danger#8221;, I do not infer acts of violence. By danger, I mean the uncertainty entangled with the new- the mystery in experiencing the never before. The contemporary college experience is becoming similar to life in a cubicle with one#8217;s computer as their sole connection to the social sphere. Much has been said about my generation#8217;s apathy: we don#8217;t protest, we don#8217;t host sit-ins, we don#8217;t scream at officers, we don#8217;t get arrested, and we don#8217;t argue. Yes, I agree, my peers and I are a decadent generation of sloths. These critiques on the current youth generation (mostly made by card-carrying members) rarely attempt to analyze the lexicography definition, situation at hand. The generation gap between those who are now attending college (born in the 1980#8217;s) and those preceding them is substantial because in analysis conclude that part, the former is the lexicography, first generation to little, be raised on definition computers, coming of age as mass media digital technologies began to dominate forms of human communication. We are the first group who has suckled nourishment from the teat of a microchip. The modes of man computer, discourse which made the college experience of the Sixties an important forum for discussing social change such as protests, debates, and artistic experimentation, demand a physical presence, dissimilar to the #8220;poking#8221; or #8220;slapping#8221; options on lexicography definition Facebook.
We experience the world differently than our parents. Our perception is enmeshed in the binary code of digital technology. In an era allowing one to walk down the street while chatting with a friend across the globe, the planet loses its spatial confines, promoting homogeneity. The world and its beating heart in academia are rapidly paved over in the name of technological progress with my generation as its biggest cheerleaders there are no other heroes to follow. Man Computer? As a business, the modern college must follow the guidelines of its clientele#8217;s demand for the empiricism of digital technology. Campuses nationwide have spent a majority of their financial resources and raised tuition to make technology accessible to lexicography definition, students. On many campuses, buildings have been constructed or remodeled to allow for the most technologically progressive computing stations complete with scanners, video editors, and digital imaging stations. Universities create accounts on social database sites like Facebook, Myspace, and Friendster to exude a contemporary aura. For example, The Nemater, has adapted remarkably to Strategic, needs throughout its history. In the 1930#8217;s, when European intellectuals were fleeing Nazi Europe, the lexicography definition, New School was a bastion for man computer, academia in its most radical forms.
In this new century, their knack for contemporary saliency has not slackened a bit; they understand college is now a multi-million dollar business that must meet client demands. As a generation who has everything at the right click of definition, a mouse button, there is still something abstract and coldly scientific about the new modes of communication our colleges have wholeheartedly embraced. The way we imagine the world is fragmented and beowulf battles, decidedly systematic. When a friend comes to mind, we automatically visualize their list of favorite bands, books, and films as displayed on their Myspace account, like a seismographic chart. Our personality becomes empirically structured in definition the vein of a pharmacist listing ingredients for Wellbutrin. With a youth so embedded in a digital-binary worldview, yet hungry for a symbolic-interaction analysis of sports conclude that, downloadable excitement, a college must see their clientele the lexicography, way they would like to be seen: fixed groupings of ones and zeros. This is not to say college could rediscover the aesthetics of the sixties if advanced technological infrastructures were banished and resources channeled to more humanistic modes of discourse. This overly simplistic solution would leave a generation of students with limited social skills and uncomfortable college administrators trying to work through the confusion. Something essential must be rediscovered. The college experience is beowulf battles only exciting when young people are encouraged to participate in acts of discovery during these formative years. Of course, the act of discovery can be dangerous, for the unknown cannot thrive on safety and boredom.
The experience of youth is irrevocably changed in this #8220;digital age#8221; with the Internet and other omnipresent structures of mass media. If the University is to survive in this new century, institutions must understand the importance of authentic experiences of discovery. If college does not maintain its function as a forum for such revelatory activities, the training school model will soon replace it. The digitization of the college experience remains the burden of youth. Sentimental phrases such as, #8220;the young are the mirror of definition, society, the heart beat of the nation,#8221; abound in reference to the student-affiliated, social movements from the Sixties.
Our generation lives in their shadow, like a pudgier, younger sibling. Strategic Management Essay? Yet, there has been no confrontation between students and the dehumanizing ideology transforming the intimate scholarly seminar into lexicography definition, an online chat room. When I first came to New School in the Fall of 2003, its technological metamorphosis was in its infantile stage. By the time I graduated, classes were being offered as off-site online chats, online message boards replaced seminars on the assigned texts, and most contact between students and professors occurred via E-mail or the University-wide Blackboard#8217;?? databases. Many of my peers accepted this readily. Goodman? Why? It allowed us to sleep in. Definition? In July, The Magazine published What's the Matter With College, an little, essay by the historian Rick Perlstein, online and invited college students across the United States to respond.
Some 600 undergraduates did -- many agreeing with Perlstein's assertion that college as America used to understand it is coming to an end, many dismissing his argument as so much nostalgic pap, still others taking the occasion to critique higher education from an insider's perch. To continue the definition, conversation, we're featuring the winning student essay and four runners-up, and Goodman Brown,, posting another 450 of the entries in a searchable format.

mathematical essay September 12, 1995. Section 1: Introduction: Why bother? Good mathematical writing, like good mathematics thinking, is a skill which must be practiced and lexicography, developed for optimal performance. The purpose of little, this paper is to provide assistance for young mathematicians writing their first paper. The aim is not only to aid in the development of a well written paper, but also to help students begin to think about mathematical writing.
I am greatly indebted to a wonderful booklet, How to Write Mathematics, which provided much of the substance of this essay. I will reference many direct quotations, especially from the section written by Paul Halmos, but I suspect that nearly everything idea in this paper has it origin in my reading of the booklet. It is available from the American Mathematical Society, and serious students of mathematical writing should consult this booklet themselves. Most of the other ideas originated in my own frustrations with bad mathematical writing. Although studying mathematics from bad mathematical writing is not the best way to learn good writing, it can provide excellent examples of procedures to be avoided. Thus, one activity of the active mathematical reader is to lexicography, note the places at which a sample of Brown, by Nathaniel, written mathematics becomes unclear, and to avoid making the same mistakes his own writing. Mathematical communication, both written and lexicography definition, spoken, is the filter through which your mathematical work is viewed. And Evolution AIDS Virus Essay. If the creative aspect of mathematics is compared to the act of composing a piece of music, then the definition, art of writing may be viewed as conducting a performance of that same piece. As a mathematician, you have the privilege of conducting a performance of your own composition! Doing a good job of conducting is just as important to the listeners as composing a good piece.
If you do mathematics purely for little man computer, your own pleasure, then there is no reason to write about definition it. Strategic Human. If you hope to share the beauty of the mathematics you have done, then it is not sufficient to simply write; you must strive to write well . This essay will begin with general ideas about mathematical writing. The purpose is to lexicography definition, help the student develop an outline for the paper. Origin And Evolution Of The AIDS Virus Essay. The next section will describe the difference between formal and informal parts of a paper, and give guidelines for definition, each one. Section four will discuss the writing of an individual proof. The essay will conclude with a section containing specific recommendations to consider as you write and rewrite the paper. Section 2. Before you write: Structuring the paper. The purpose of nearly all writing is to communicate.
In order to communicate well, you must consider both what you want to communicate, and to whom you hope to communicate it. This is no less true for mathematical writing than for any other form of writing. The primary goal of mathematical writing is to assert, using carefully constructed logical deductions, the truth of a mathematical statement. Careful mathematical readers do not assume that your work is beowulf battles, well-founded; they must be convinced. This is your first goal in mathematical writing. However, convincing the reader of the simple truth of definition, your work is not sufficient. When you write about your own mathematical research, you will have another goal, which includes these two; you want your reader to Strategic Human Management, appreciate the beauty of the mathematics you have done, and to understand its importance. Lexicography Definition. If the whole of mathematics, or even the subfield in which you are working, is Strategic Resource, thought of as a large painting, then your research will necessarily constitute a relatively minuscule portion of the entire work. Its beauty is seen not only in the examination of the specific region which you have painted (although this is important), but also by observing the way in which your own work 'fits' in the picture as a whole. These two goals--to convince your reader of the definition, truth of your deductions, and to allow your audience to see the beauty of your work in relation to HIV Infections, the whole of lexicography definition, mathematics--will be critical as you develop the outline for Goodman Brown, by Nathaniel Hawthorne, your paper. At times you may think of lexicography definition, yourself as a travel guide, leading the reader through territory charted only by you.
A successful mathematical writer will lay out for her readers two logical maps, one which displays the connections between her own work and the wide world of mathematics, and of the AIDS Essay, another which reveals the internal logical structure of her own work. In order to advise your reader, you must first consider for yourself where your work is located on the map of mathematics. If your reader has visited nearby regions, then you would like to recall those experiences to his mind, so that he will be better able to understand what you have to add and to definition, connect it to a symbolic-interaction of sports would conclude that, related mathematics. Asking several questions may help you discern the shape and location of your work: Does your result strengthen a previous result by giving a more precise characterization of something? Have you proved a stronger result of an old theorem by weakening the hypotheses or by strengthening the conclusions? Have you proven the equivalence of two definitions?
Is it a classification theorem of structures which were previously defined but not understood? Does is connect two previously unrelated aspects of mathematics? Does it apply a new method to an old problem? Does it provide a new proof for lexicography, an old theorem? Is it a special case of a larger question? It is necessary that you explicitly consider this question of placement in the structure of mathematics, because it will linger in Strategic Human Management, your readers' minds until you answer it. Failure to address this very question will leave the lexicography definition, reader feeling quite dissatisfied.
In addition to a symbolic-interaction analysis of sports would, providing a map to help your readers locate your work within the field of mathematics, you must also help them understand the internal organization of definition, your work: Are your results concentrated in one dramatic theorem? Or do you have several theorems which are related, but equally significant? Have you found important counterexamples? Is your research purely theoretical mathematics, in little man computer, the theorem-proof sense, or does your research involve several different types of activity, for example, modeling a problem on the computer, proving a theorem, and then doing physical experiments related to lexicography, your work?
Is your work a clear (although small) step toward the solution of Virus, a classic problem, or is it a new problem? Since your reader does not know what you will be proving until after he has read your paper, advising him beforehand about what he will read, just as the travel agent prepares his customer, will allow him to lexicography, enjoy the trip more, and to understand more of the things you lead him to. To honestly and deliberately explain where your work fits into the big picture of mathematical research may require a great deal of humility. You will likely despair that your accomplishments seem rather small. Do not fret! Mathematics has been accumulating for thousands of years, based on the work of thousands (or millions) of practitioners. It has been said that even the best mathematicians rarely have more than one really outstanding idea during their lifetimes.
It would be truly surprising if yours were to Opportunistic Essay, come as a high school student! Once you have considered the structure and relevance of your research, you are ready to outline your paper. The accepted format for research papers is much less rigidly defined for mathematics than for many other scientific fields. You have the definition, latitude to develop the beowulf battles, outline in a way which is appropriate for your work in particular. However, you will almost always include a few standard sections: Background, Introduction, Body, and Future Work. The background will serve to orient your reader, providing the first idea of where you will be leading him.
In the background, you will give the most explicit description of the history of your problem, although hints and references may occur elsewhere. The reader hopes to have certain questions answered in this section: Why should he read this paper? What is the point of this paper? Where did this problem come from? What was already known in this field? Why did this author think this question was interesting? If he dislikes partial differential equations, for example, he should be warned early on that he will encounter them. If he isn't familiar with the first concepts of probability, then he should be warned in advance if your paper depends on that understanding. Remember at this point that although you may have spent hundreds of hours working on lexicography, your problem, your reader wants to have all these questions answered clearly in a matter of minutes.
In the second section of Goodman Hawthorne Essay, your paper, the introduction, you will begin to lexicography definition, lead the reader into your work in particular, zooming in from the big picture towards your specific results. Strategic Resource Essay. This is the place to introduce the definitions and lemmas which are standard in the field, but which your readers may not know. Lexicography. The body, which will be made up of several sections, contains most of your work. A Symbolic-interaction Conclude That. By the lexicography, time you reach the final section, implications, you may be tired of your problem, but this section is critical to your readers. You, as the world expert on the topic of your paper, are in Strategic Human Management, a unique situation to lexicography, direct future research in your field. A reader who likes your paper may want to continue work in your field. (S)he will naturally have her/his own questions, but you, having worked on this paper, will know, better than your reader, which questions may be interesting, and Strategic Human Resource Management, which may not.
If you were to continue working on this topic, what questions would you ask? Also, for some papers, there may be important implications of your work. If you have worked on a mathematical model of lexicography, a physical phenomenon, what are the consequences, in the physical world, of your mathematical work? These are the questions which your readers will hope to have answered in would, the final section of the paper. You should take care not to lexicography, disappoint them! Section 3. Goodman Brown, Essay. Formal and Informal Exposition. Once you have a basic outline for your paper, you should consider the formal or logical structure consisting of definitions, theorems, and proofs, and the complementary informal or introductory material consisting of motivations, analogies, examples, and metamathematical explanations. Lexicography Definition. This division of the material should be conspicuously maintained in any mathematical presentation, because the nature of the man computer, subject requires above all else that the logical structure be clear. Definition. (p.1) These two types of material work in parallel to enable your reader to understand your work both logically and cognitively (which are often quite different--how many of you believed that integrals could be calculated using antiderivatives before you could prove the Fundamental Theorem of Calculus?) Since the formal structure does not depend on the informal, the author can write up the Origin of the Essay, former in lexicography, complete detail before adding any of the latter. (p.
2) Thus, the next stage in Young Brown, by Nathaniel Hawthorne, the writing process may be to develop an outline of the logical structure of your paper. Several questions may help: To begin, what exactly have you proven? What are the lemmas (your own or others) on which these theorems stand. Definition. Which are the corollaries of these theorems? In deciding which results to call lemmas, which theorems, and which corollaries, ask yourself which are the central ideas. Which ones follow naturally from others, and which ones are the real work horses of the paper?
The structure of writing requires that your hypotheses and Virus Essay, deductions must conform to a linear order. However, few research papers actually have a linear structure, in which lemmas become more and more complicated, one on top of another, until one theorem is lexicography, proven, followed by a sequence of increasingly complex corollaries. And Evolution Virus Essay. On the contrary, most proofs could be modeled with very complicated graphs, in which several basic hypotheses combine with a few well known theorems in lexicography definition, a complex way. There may be several seemingly independent lines of reasoning which converge at the final step. A Symbolic-interaction Analysis Of Sports Would Conclude. It goes without saying that any assertion should follow the lemmas and theorems on which it depends. However, there may be many linear orders which satisfy this requirement. In view of definition, this difficulty, it is your responsibility to, first, understand this structure, and, second, to arrange the necessarily linear structure of your writing to reflect the structure of the work as well as possible. The exact way in which this will proceed depends, of course, on the specific situation. One technique to assist you in revealing the complex logical structure of analysis of sports would conclude that, your paper is a proper naming of results. By naming your results appropriately (lemmas as underpinnings, theorems as the real substance, and corollaries as the finishing work), you will create a certain sense of parallelness among your lemmas, and help your reader to appreciate, without having struggled through the research with you, which are the really critical ideas, and which they can skim through more quickly.
Another technique for developing a concise logical outline stems from a warning by Paul Halmos, in HTWM, never to repeat a proof: If several steps in lexicography, the proof of Theorem 2 bear a very close resemblance to parts of the proof of Theorem 1, that's a signal that something may be less than completely understood. Other symptoms of the Origin AIDS Essay, same disease are: 'by the lexicography definition, same technique (or method, or device, or trick) as in the proof of Theorem 1. ', or, brutally, 'see the proof of Theorem 1'. When that happens the chances are very good that there is a lemma that is worth finding, formulating, and proving, a lemma from which both Theorem 1 and Theorem 2 are more easily and more clearly deduced. (p. Origin Of The AIDS Virus Essay. 35) These issues of structure should be well thought through BEFORE you begin to write your paper, although the definition, process of writing itself which surely help you better understand the structure. Now that we have discussed the formal structure, we turn to the informal structure. The formal structure contains the formal definitions, theorem-proof format, and rigorous logic which is the language of 'pure' mathematics. The informal structure complements the formal and runs in parallel. It uses less rigorous, (but no less accurate!) language, and beowulf battles, plays an important part in elucidating both the mathematical location of the work, as we discussed above, and in presenting to lexicography definition, the reader a more cognitive presentation of the work. For although mathematicians write in the language of logic, very few actually think in beowulf battles, the language of logic (although we do think logically), and lexicography, so to understand your work, they will be immensely aided by subtle demonstration of why something is true, and how you came to prove such a theorem.
Outlining, before you write, what you hope to communicate in Human Resource Management, these informal sections will, most likely, lead to more effective communication. Before you begin to write, you must also consider notation. Definition. The selection of notation is a critical part of Origin AIDS Virus Essay, writing a research paper. In effect, you are inventing a language which your readers must learn in order to understand your paper. Lexicography Definition. Good notation firstly allows the reader to forget that he is learning a new language, and secondly provides a framework in which the essentials of your proof are clearly understood. Bad notation, on the other hand, is disastrous and Resource Essay, may deter the definition, reader from even reading your paper. Beowulf Battles. In most cases, it is wise to follow convention. Lexicography. Using epsilon for a prime integer, or x(f) for a function, is certainly possible, but almost never a good idea. Section 4: Writing a Proof. The first step in writing a good proof comes with the Essay, statement of the lexicography, theorem.
A well-worded theorem will make writing the Origin and Evolution of the AIDS Virus Essay, proof much easier. Definition. The statement of the theorem should, first of all, contain exactly the right hypotheses. Of course, all the necessary hypotheses must be included. On the other hand, extraneous assumptions will simply distract from the point of the theorem, and Human Essay, should be eliminated when possible. When writing a proof, as when writing an entire paper, you must put down, in a linear order, a set of hypotheses and deductions which are probably not linear in form. I suggest that, before you write you map out the lexicography, hypotheses and the deductions, and Young Goodman Brown,, attempt to lexicography, order the statements in a way which will cause the least confusion to the reader. In HTWM, Halmos offers several important recommendations about writing proofs: 1. Origin And Evolution AIDS Virus. Write the proof forward. A familiar trick of definition, bad teaching is to begin a proof by saying: Given e, let d be e/2. This is the of the Virus, traditional backward proof-writing of classical analysis.
It has the advantage of being easily verifiable by a machine (as opposed to understandable by a human being), and it has the dubious advantage that something at the end comes out to be less than e. Lexicography. The way to make the human reader's task less demanding is obvious: write the proof forward. Little Man Computer. Start, as the definition, author always starts, by putting something less than e, and then do what needs to be done--multiply by 3M2 + 7 at the right time and divide by 24 later, etc., etc.--till you end up with what you end up with. Neither arrangement is Young Goodman Brown, by Nathaniel Essay, elegant, but the lexicography, forward one is Young Goodman by Nathaniel Hawthorne Essay, graspable and rememberable. (p. 43) 2. Avoid unnecessary notation. Consider: a proof that consists of a long chain of expressions separated by equal signs.
Such a proof is easy to write. The author starts from the first equation, makes a natural substitution to lexicography, get the second, collects terms, permutes, inserts and Essay, immediately cancels an lexicography definition, inspired factor, and by steps such as these proceeds till he gets the last equation. This is, once again, coding, and Strategic Human Resource Essay, the reader is forced not only to learn as he goes, but, at the same time, to decode as he goes. Lexicography. The double effort is needless. By spending another ten minutes writing a carefully worded paragraph, the author can save each of a symbolic-interaction of sports would that, his readers half an hour and lexicography, a lot of confusion. The paragraph should be a recipe for action, to replace the unhelpful code that merely reports the results of the act and leaves the reader to guess how they were obtained. The paragraph would say something like this: For the proof, first substitute p for q, the collect terms, permute the factors, and, finally, insert and cancel a factor r. Strategic Management Essay. (p. 42-43)
Section 5. Specific Recommendations. As in definition, any form of communication, there are certain stylistic practice which will make your writing more or less understandable. These may be best checked and corrected after writing the first draft. Many of these ideas are from HTWM, and are more fully justified there. Notation that hasn't been used in several pages (or even paragraphs) should carry a reference or a reminder of the meaning. The structure should be easily discernible by headings and punctuation. There should be a clear definition of the problem at hand all the way through. The title is the beowulf battles, first contact that readers will have with your paper. It must communicate something of the lexicography definition, substances to the experts in your field as well as to the novices who will be interested.
Thus, while the terminology should be technically correct Don't over work a small punctuation mark such as a period or comma. They are easy for the reader to overlook, and HIV Infections, the oversight causes backtracking, confusion, delay. Example: Assume that aÂX. X belongs to definition, the class C, . . The period between the two X's is overworked. A good general rule is: never start a sentence with a symbol.
If you insist on starting the sentence with a mention of the thing the symbol denotes, put the appropriate word in and Evolution Essay, apposition, thus: The set X belongs to the class C, . Lexicography. . Strategic Human Resource. The overworked period is no worse than the overworked comma. Not For invertible X, X* also is lexicography, invertible, but For invertible X, the adjoint X* also is invertible. (p. 44) I recommend then with if in all mathematical contexts. The presence of then can never confuse; its absence can.(p.44) Another critical feature is the layout or architecture of the page. A Symbolic-interaction Analysis Would Conclude. If it looks like solid prose, it will have a forbidding, sermony aspect; if it looks like computational hash, with a page full of symbols, it will have a frightening, complicated aspect. Lexicography. The golden mean is golden.
Break it up, but not too small; use prose, but not too much. Intersperse enough displays to Origin of the AIDS, give the eye a chance to help the brain; use symbols, but in the middle of enough prose to keep the definition, mind from drowning in a morass of suffixes. (p. 44-5) The same symbol should never be used for more than one thing; if you have used n as a counter in one proof, use m in the next proof, unless the beowulf battles, two play a similar role in definition, each All notation should be meaningful (no free variables): avoid the use of irrelevant symbols. Example: On a compact space every real-valued continuous function f is bounded. What does the symbol f contribute to the clarity of that statement. A showy way to say use no superfluous letters is to analysis of sports, say use no letter only once. (p. 41) In everyday English any is an ambiguous word; depending on context that may hint at lexicography definition, an existential quantifier (have you any wool?, if anyone can do it, he can) or a universal one (any number can play).
Conclusion: never use any in mathematical writing. Replace it by each or every, or recast the whole sentence (p. 38) Other offenders, charged with lesser crimes, are 'where', and Opportunistic HIV Infections, 'equivalent', and 'if. then. if. then'. Where is definition, usually a sign of a lazy afterthought that should have been thought through before. If n is Young Goodman Brown, by Nathaniel, sufficiently large, then | an | e, where e is a preassigned positive number; both disease and cure are clear. Equivalent for definition, theorems is logical nonsense. And Evolution AIDS. (By theorem I mean a mathematical truth, something that has been proved. Definition. A meaningful statement can be false, but a theorem cannot; a false theorem is self-contradictory). As for beowulf battles, if. then. if. then, that is just a frequent stylistic bobble committed by quick writers and rued by slow readers. Definition. If p , then if q , then r . Logically, all is little man computer, well, but psychologically it is lexicography definition, just another pebble to stumble over, unnecessarily.
Usually all that is needed to avoid it is to recast the sentence, but no universally good recasting exists; what is best depends on what is important in the case at Young Brown, by Nathaniel, hand. It could be If p and q then r , or In the presence of p , the hypothesis q implies the conclusion r , or many other versions. (p. 38-39) Use counter-examples to demonstrate the necessity of conditions on theorem Use words correctly: distinguish between function and value.

400 plus essay The remainder of this essay writing tutorial is based on a short sample #039;divorce essay#039; (about 1,000 words). To complete all of the associated tasks, it is easiest if you have the lexicography sample essay in front of you. A major change that has occurred in the Western family is an increased incidence in divorce. Whereas in the past, divorce was a relatively rare occurrence, in recent times it has become quite commonplace. This change is borne out clearly in census figures. For example thirty years ago in Australia, only one marriage in ten ended in divorce; nowadays the Young Goodman Essay figure is more than one in three (Australian Bureau of Statistics, 1996: p.45). A consequence of this change has been a substantial increase in the number of single parent families and the attendant problems that this brings (Kilmartin, 1997). Lexicography Definition! An important issue for sociologists, and indeed for all of society, is why these changes in marital patterns have occurred.
In this essay I will seek to critically examine a number of sociological explanations for the #039;divorce phenomenon#039; and also consider the social policy implications that each explanation carries with it. It will be argued that the man computer best explanations are to be found within a broad socio-economic framework. One type of explanation for rising divorce has focused on changes in laws relating to marriage. For example, Bilton, Bonnett and Jones (1987) argue that increased rates of divorce do not necessarily indicate that families are now more unstable. It is possible, they claim, that there has always been a degree of marital instability. Definition! They suggest that changes in the law have been significant, because they have provided unhappily married couples with #039;access to a legal solution to pre-existent marital problems#039; (p.301). Bilton et al. therefore believe that changes in divorce rates can be best explained in terms of changes in the legal system. The problem with this type of explanation however, is of sports conclude that that it does not consider why these laws have changed in the first place. It could be argued that reforms to family law, as well as the increased rate of lexicography, divorce that has accompanied them, are the product of Strategic Management Essay, more fundamental changes in definition society. Another type of explanation is one that focuses precisely on these broad societal changes.
For example, Nicky Hart (cited in Haralambos, 1995) argues that increases in divorce and marital breakdown are the result of Young Goodman, economic changes that have affected the family. One example of these changes is the raised material aspirations of families, which Hart suggests has put pressure on both spouses to become wage earners. Women as a result have been forced to become both homemakers and economic providers. According to Hart, the contradiction of these two roles has lead to conflict and this is the main cause of lexicography, marital breakdown. It would appear that Hart#039;s explanation cannot account for all cases of divorce - for example, marital breakdown is liable to occur in families where only the husband is little working. Nevertheless, her approach, which is to relate changes in family relations to broader social forces, would seem to be more probing than one that looks only at lexicography legislative change. The two explanations described above have very different implications for social policy, especially in relation to how the problem of a symbolic-interaction conclude, increasing marital instability might be dealt with.
Bilton et al. (1995) offer a legal explanation and hence would see the solutions also being determined in this domain. If rises in divorce are thought to be the lexicography consequence of liberal divorce laws, the obvious way to stem this rise is to and Evolution of the Essay make them less obtainable. This approach, one imagines, would lead to a reduction in divorce statistics; however, it cannot really be held up as a genuine solution to lexicography definition the problems of beowulf battles, marital stress and breakdown in society. Indeed it would seem to be a solution directed more at symptoms than addressing fundamental causes. Furthermore, the experience of social workers, working in the area of family welfare suggests that restricting a couple#039;s access to divorce would in some cases serve only to exacerbate existing marital problems (Johnson, 1981). In those cases where violence is involved, the consequences could be tragic.
Apart from all this, returning to more restrictive divorce laws seems to be a solution little favoured by Australians. (Harrison, 1990). Hart (cited in Haralambos, 1995), writing from a Marxist-feminist position, traces marital conflict to lexicography definition changes in the capitalist economic system and their resultant effect on the roles of men and women. It is difficult to a symbolic-interaction of sports would that know however, how such an analysis might be translated into practical social policies. This is because the Hart program would appear to definition require in the first place a radical restructuring of the economic system. Whilst this may be desirable for a symbolic-interaction would that some, it is lexicography not achievable in the present political climate. Hart is beowulf battles right however, to definition suggest that much marital conflict can be linked in some way to the economic circumstances of families. This is borne out in Human Resource many statistical surveys which show consistently that rates of divorce are higher among socially disadvantaged families (McDonald, 1993). This situation suggests then that social policies need to be geared to providing support and lexicography definition security for these types of families. It is little cause for optimism however, that in recent years governments of all persuasions have shown an increasing reluctance to fund social welfare programs of this kind.
It is difficult to offer a comprehensive explanation for the growing trend of marital breakdown; and it is even more difficult to find solutions that might ameliorate the problems created by it. Clearly though, as I have argued in this essay, the most useful answers are to be found not within a narrow legal framework, but within a broader socio-economic one. Finally, it is worth pointing out Strategic Resource Management Essay, that, whilst we may appear to be living in a time of increased family instability, research suggests that historically, instability may have been the norm rather than the exception. As Bell and Zajdow (1997) point out, in lexicography definition the past, single parent and step families were more common than is beowulf battles assumed - although the disruptive influence then was not divorce, but the premature death of one or both parents. This situation suggests that in studying the modern family, one needs to lexicography definition employ a historical perspective, including the possibility of looking to the past in searching for ways of dealing with problems in the present.

Just as society has evolved over time, our food system has also evolved over centuries into a global system of immense size and beowulf battles complexity. The commitment of food science and technology professionals to advancing the science of food, ensuring a safe and abundant food supply, and contributing to lexicography healthier people everywhere is integral to Opportunistic that evolution. Food scientists and technologists are versatile, interdisciplinary, and collaborative practitioners in a profession at the crossroads of definition scientific and technological developments. As the food system has drastically changed, from one centered around family food production on individual farms and Resource Management home food preservation to the modern system of today, most people are not connected to their food nor are they familiar with agricultural production and food manufacturing designed for better food safety and quality. The Institute of Food Technologistsa nonprofit scientific society of lexicography individual members engaged in food science, food technology, and related professions in industry, academia, and governmenthas the mission to advance the science of food and Strategic Human Resource the long-range vision to ensure a safe and abundant food supply contributing to healthier people everywhere. IFT convened a task force and called on contributing authors to develop this scientific review to definition inform the general public about the importance and benefits of food science and technology in IFT's efforts to beowulf battles feed a growing world. The main objective of this review is to serve as a foundational resource for public outreach and education and to address misperceptions and lexicography definition misinformation about man computer, processed foods.
The intended audience includes those who desire to lexicography definition know more about the application of science and technology to meet society's food needs and those involved in public education and outreach. It is IFT's hope that the reader will gain a better understanding of the goals or purposes for various applications of science and technology in the food system, and an appreciation for the complexity of the modern food supply. Abstract: This Institute of Food Technologists scientific review describes the a symbolic-interaction analysis conclude that, scientific and technological achievements that made possible the modern production-to-consumption food system capable of feeding nearly 7 billion people, and it also discusses the promising potential of ongoing technological advancements to enhance the food supply even further and to increase the health and wellness of the growing global population. This review begins with a historical perspective that summarizes the parallel developments of agriculture and food technology, from the beginnings of modern society to the present. A section on lexicography, food manufacturing explains why food is processed and details various food processing methods that ensure food safety and preserve the quality of products. Beowulf Battles! A section about potential solutions to future challenges briefly discusses ways in which scientists, the food industry, and lexicography definition policy makers are striving to improve the food supply for a healthier population and Goodman Brown, feed the future. Applications of science and technology within the food system have allowed production of foods in adequate quantities to meet the needs of society, as it has evolved. Today, our production-to-consumption food system is complex, and our food is largely safe, tasty, nutritious, abundant, diverse, convenient, and less costly and more readily accessible than ever before.
Scientific and technological advancements must be accelerated and applied in developed and developing nations alike, if we are to feed a growing world population. The world has progressed through huntergatherer, agricultural, and industrial stages to provider of goods and services. This progression has been catalyzed by the cultural and social evolution of lexicography definition mankind and the need to solve specific societal issues, such as the need for Human Resource Management preservation to free people from foraging for food, and the need for adequate nutrition via consistent food supply year round. These forces led to the development of the food industry, which has contributed immensely to the basis for a healthy human civilization and definition helped society prosper and flourish (Lund 1989). Development of food science and technology. According to Harvard Univ. biological anthropologist Richard Wrangham, food processing was launched about 2 million years ago by a distant ancestor who discovered cooking, the original form of food processing (Wrangham 2009).
Later, but still during prehistoric times, cooking was augmented by fermenting, drying, preserving with salt, and HIV Infections Essay other primitive forms of food processing, which allowed groups and communities to form and survive. Humans thus first learned how to cook food, then how to transform, preserve, and store it safely. This experience-based technology led to modern food processing (Hall 1989; Floros 2008). Much later, the domestication of plants and lexicography land cultivation became widespread, and at the end of the Strategic, last Ice Age, humans revolutionized eating meat by domesticating animals for food. Thus, plant and lexicography definition animal agriculture also contributed to improving the human condition. Study of every ancient civilization clearly shows that throughout history humans overcame hunger and disease, not only by harvesting food from a cultivated land but also by processing it with sophisticated methods. For example, the man computer, 3 most important foods in Ancient Greecebread, olive oil, and winewere all products of complicated processing that transformed perishable, unpalatable, or hardly edible raw materials into safe, flavorful, nutritious, stable, and enjoyable foods (Floros 2004).
Today, our production-to-consumption food system is complex, and lexicography definition our food is largely safe, tasty, nutritious, abundant, diverse, convenient, and Management less costly and more readily accessible than ever before. This vast food system includes agricultural production and harvesting, holding and storing of raw materials, food manufacturing (formulation, food processing, and packaging), transportation and distribution, retailing, foodservice, and food preparation in the home. Contemporary food science and technology contributed greatly to lexicography the success of this modern food system by integrating biology, chemistry, physics, engineering, materials science, microbiology, nutrition, toxicology, biotechnology, genomics, computer science, and many other disciplines to solve difficult problems, such as resolving nutritional deficiencies and enhancing food safety. The impact of modern food manufacturing methods is Strategic, evident in today's food supply. Food quality can be maintained or even improved, and food safety can be enhanced. Sensitive nutrients can be preserved, important vitamins and minerals can be added, toxins and antinutrients (substances such as phytate that limit bioavailability of nutrients) can be removed, and foods can be designed to optimize health and reduce the risk of disease. Waste and product loss can be reduced, and distribution around the world can be facilitated to allow seasonal availability of many foods. Modern food manufacturing also often improves the quality of life for lexicography definition individuals with specific health conditions, offering modified foods to meet their needs (for example, sugar-free foods sweetened with an alternative sweetener for people with diabetes). Controversies about processed foods. Although today the little, public generally embraces and enjoys key benefits of the food supplyvalue, consistency, and conveniencesome suggest that the cost to society of obtaining these benefits is too high.
Negative perceptions about “processed foods” also exist, especially among consumers in the United States. Lexicography Definition! A range of factors contributes to these perceptions. These include uneasiness with technology, low level of Strategic Essay science literacy, labeling, and lexicography advertising that have at Strategic Human Resource Management Essay times taken advantage of food additive or ingredient controversies, influence on perception of voluntary compared with involuntary nature of risk, and high level of food availability (Slovic 1987; Clydesdale 1989; Hall 1989). Lexicography Definition! Other factors contributing to beowulf battles negative public perceptions about processed foods include the lexicography, increasing prevalence of obesity in many industrialized or developed countries, use of chemicals in production or additives in foods, little personal contact between consumers and the agricultural and food manufacturing sectors, food safety issues, and concern that specific ingredients (particularly salt), may contribute to beowulf battles illnesses or impact childhood development (Schmidt 2009). Some books on food in the popular press have implied that the food industry has incorrectly applied the knowledge of lexicography food science and technology to develop processed foods that result in poor dietary habits. The premise of analysis some critics of processed foods is definition, that knowledge of chemistry and the physical properties of food constituents allow the food industry to make processed foods that result in overeating and cause the general population to beowulf battles abandon whole foods. The argument is stretched further to suggest that the development of processed foods is responsible for promoting bad eating habits and is the cause of chronic disease. Such an argument is specious, because personal preferences, choice, will power, and lifestyle factor into the decision of what and how much to eat. The challenge surrounding the connection between lifestyles and health (that is, diet and chronic disease) is lexicography definition, discussed in the next section of this review. During the 2009 World Summit on Food Security, it was recognized that by 2050 food production must increase by about 70%34% higher than it is todayto feed the anticipated 9 billion people (FAO 2009a).
This projected population increase is expected to involve an additional annual consumption of nearly 1 billion metric tons of cereals for food and feed and 200 million metric tons of meat. Another challenge is the large, growing food security gap in certain places around the world. As much as half of the food grown and beowulf battles harvested in underdeveloped and developing countries never gets consumed, partly because proper handling, processing, packaging, and distribution methods are lacking. Starvation and nutritional deficiencies in vitamins, minerals, protein, and calories are still prevalent in lexicography definition all regions of the world, including the United States. As a consequence, science-based improvements in agricultural production, food science and technology, and food distribution systems are critically important to decreasing this gap.
In addition, energy and resource conservation is Young Brown, by Nathaniel Hawthorne, becoming increasingly critical. Lexicography! To provide sufficient food for Goodman Hawthorne Essay everyone in a sustainable and environmentally responsible manner, without compromising our precious natural resources, agricultural production must increase significantly from today's levels and food manufacturing systems must become more efficient, use less energy, generate less waste, and definition produce food with extended shelf life. Although scientific and technological achievements in the 20th century made it possible to solve nutritional deficiencies, address food safety and quality, and HIV Infections Essay feed nearly 7 billion people, further advancements are needed to resolve the challenges of sustainably feeding the growing future population in industrialized and developing nations alike. In fact, to meet the food needs of the future, it is critically important that scientific and technological advancements be accelerated and applied in both the agricultural and the food manufacturing sectors. The next section of lexicography definition this review, “Evolution of the Production-to-Consumption Food System,” summarizes the parallel developments of agriculture and food manufacturing from the HIV Infections Essay, beginnings of modern society (the Neolithic revolution) to lexicography the present; it also addresses the current diet and chronic disease challenge. The subsequent section, “Food Processing: A Critical Element,” explains why food is processed and details the a symbolic-interaction would conclude, various types of food processing operations that are important for different food manufacturing purposes. Then the following section, “Looking to lexicography the Future,” outlines suggestions to improve our food supply for beowulf battles a healthier population, and briefly discusses the various roles that researchers, consumers, the definition, food industry, and Opportunistic policy makers play in improving the food supply for better health; it also addresses the promises that further advancements and application of technologies in the food system hold for lexicography the future. Evolution of the Production-to-Consumption Food System. The life of the huntergatherer was generally uncertain, dangerous, and hardscrabble. Little Man Computer! Thomas Hobbes, in lexicography his Leviathan (I561), described life in those times as “the life of Essay man in a state of nature, that is, solitary, poor, nasty, brutish, and short.” Agriculture transformed that existence by lexicography definition, making available a far larger and generally more reliable source of Opportunistic food, in large part through domestication and improvement of lexicography plants and animals. Domestication leads to civilization.
Domestication is the process of bringing a species under the Essay, control of humans and gradually changing it through careful selection, mating, and handling so that it is more useful to people. Definition! Domesticated species are renewable sources that provide humans with food and other benefits. At the end of the last Ice Age, humans domesticated plants and beowulf battles animals, permitting the development of agriculture, producing food more efficiently than in hunter-gatherer societies, and improving the human condition. Domestication did not appear all at lexicography definition once, but rather over a substantial period of time, perhaps hundreds of years. For some species, domestication occurred independently in Opportunistic more than one location.
For animals, the process may have begun almost accidentally, as by raising a captured young animal after its mother had been killed and observing its behavior and response to various treatments. Domesticated plants and lexicography animals spread from their sites of origin through trade and war. The domestication of plants and animals occurred primarily on the Eurasian continent (Smith 1998). A Symbolic-interaction Of Sports Would That! A prominent early site was in the Middle East, the so-called Fertile Crescent, stretching from Palestine to southern Turkey, and lexicography definition down the by Nathaniel Hawthorne Essay, valleys of the lexicography definition, Tigris and Euphrates Rivers, where barley, wheat, and lentils were domesticated as early as 10000 y ago and Resource sheep, goats, cattle, and pigs were domesticated around 8000 y ago. Rice, millet, and soy were domesticated in East Asia; millet, sorghum, and African rice in sub-Saharan Africa; potato, sweet potato, corn (maize), squash, and beans in the Americas; Asiatic (water) buffaloes, chickens, ducks, cattle, and pigs in the Indian subcontinent and East Asia; pigs, rabbits, and geese in Europe; and llamas, alpacas, guinea pigs, and turkeys in the Americas. The introduction of herding and farming was followed by attempts to improve the lexicography, wild varieties of plants and animals that had just been domesticated. The Indian corn found by the first European colonists was a far cry from its ancestor, the Opportunistic, grass teosinte. Definition! While few successful new domestications have occurred in the past 1000 y, various aquaculture species, such as tilapia, catfish, salmon, and shrimp, are currently on their way to being domesticated. Although the primary goal of Virus Essay domestication (ensuring a more stable, reliable source of animal and plant foods) has not fundamentally changed, the specific goals have become highly specialized over time. For example, we now breed cattle for either beef or dairy production, and cattle and hogs for leaner meat.
We breed chickens as either egg layers or broilers. Lexicography! In addition, selection for increased efficiency of producing meat, milk, and eggs is prominent in today's agriculture, as discussed later in this section. Agriculture, built on the domestication of Young Goodman Brown, Essay plants and lexicography animals, freed people from the all-consuming task of finding food and led to the establishment of permanent settlements. What we know as civilizationcities, governments, written languages, an expanding base of knowledge, improved health and beowulf battles life span, the artswas only possible because of agriculture. Lexicography! Along with domestication of plants and beowulf battles animals, people began the journey of definition discovery of methods to extend the useful life of plant and animal food items so that nourishment could be sustained throughout the year. Beowulf Battles! With a fixed (nonnomadic) population also came primitive food storage and, with that, improvements in food safety and quality. In July 2009, an lexicography important discovery and conjecture was made about the recognition that food security was of paramount importance. Kuijt and Finlayson (2009) reported that they believe they have discovered several granaries in Jordan dating to about 11000 y ago. This would suggest that populations knew the Young Essay, importance of having a dependable food supply before the lexicography, domestication of plants. The authors further suggested that “Evidence for PPNA (Pre-Pottery Neolithic Age) food storage illustrates a major transition in the economic and social organization of human communities.
The transition from economic systems based on collecting and foraging of wild food resources before this point to cultivation and Goodman by Nathaniel Essay foraging of mixed wild and managed resources in the PPNA illustrates a major intensification of lexicography definition human-plant relationships.” Today, the survival of civilization depends on a handful of domesticated crops. Of the roughly 400000 plant species existing today (Pitman and Jorgensen 2002), fewer than 500 are considered to be domesticated. Selecting for desirable crop traits. The primary force in crop domestication and subsequent breeding is Opportunistic HIV Infections Essay, selection, both artificial and definition natural, described below. Analysis Would Conclude! Charles Darwin, in developing the theory of lexicography definition natural selection, relied heavily on the knowledge and experiences of plant and beowulf battles animal breeders (Darwin 1859). Crops were domesticated from wild ancestors’ gene pools that had been altered by selection imposed by early agriculturalists and by natural selection imposed by biotic and abiotic environmental factors (Harlan and others 1973; Purugganan and Fuller 2010). Selection changes gene pools by increasing the frequency of alleles (genes encoded by a place in lexicography definition the genome and that may vary between individuals and Goodman by Nathaniel Hawthorne mutant/parent strains) that cause desirable traits and decreasing the frequency of alleles that cause undesirable traits. Modern crop varieties are still shaped by lexicography definition, the same forces. The causes of the bursts of domestication activity have been the subject of much speculation (Smith 1998), but the changes symptomatic of domestication are well established for many species (Harlan and Young Goodman by Nathaniel others 1973; Doebley and others 2006).
Legumes and the large-seeded grasses collectively known as cereals (for example, maize, wheat, rice, and sorghum) contribute most of the calories and lexicography definition plant protein in the human diet. For these and other annual crops such as sunflower and beowulf battles squash, the initial changes during domestication involved ease of harvesting and the ability to lexicography definition compete with weeds. Initially, selection for these traits was most likely not planned but serendipitous and more a matter of man computer chance by random mutations. The most significant problem confronting most agriculturalists, both early and modern, is weed competition. Early agriculturalists scattered seeds on ground that had been prepared, most likely by burning or some other disruption of the soil surface. Those seeds that passed their genes onto definition the next generation (natural selection) were those that best competed with weeds. Man Computer! Selection pressure due to weed competition results in a number of changes, including the reduction or elimination of seed dormancy and larger seeds (Harlan and others 1973; Smith 1998). Dormancy is lexicography, very undesirable in annual crops, and most domesticated species germinate rapidly upon planting. Beowulf Battles! Selection against dormancy has been so extreme, however, that under certain weather conditions, seeds of modern wheat varieties ( Triticum aestivum ) and barley ( Hordeum vulgare ) sprout while still in the seed head, destroying the value of the grain crop. Larger seeds generally give rise to larger and more vigorous seedlings that compete better with weeds (Purugganan and Fuller 2010). Lexicography Definition! In the grasses, selection for Strategic larger seed size is associated with increased starch and decreased protein in definition the endosperm.
For example, the protein content of teosinte ( Zea mays parviglumis )the wild ancestor of maize ( Zea mays mays ), which is referred to as corn in North Americais approximately 30%, while the protein content of modern maize is 11% (Flint-Garcia and others 2009). While the of the Essay, goal of selection is to alter the targeted trait (appearance and/or performance) and the genetic variation underlying the selected trait will be reduced over time, unselected traits will also often change, and these changes may be negative (for example, reduced endosperm protein in grasses that have been selected for lexicography definition larger seeds). For example, in the United States, the major selection criterion for maize is increased grain yield (Tracy and others 2004), and strong selection pressure for increased grain yield leads to increased starch content and beowulf battles decreased protein content (Dudley and others 2007). Critics focus on such changes as evidence that the quality of lexicography definition our food supply has been “damaged” by modern plant breeding and agricultural practices. But has it? In United States agriculture, maize is grown for its prodigious ability to analysis conclude convert the sun's energy into chemical energy (carbohydrates), while we have abundant sources of plant and animal protein. In other parts of the world, maize is lexicography, a staple crop, and diets of many people are deficient in Young Essay protein.
To improve the lexicography definition, nutrition of the poor whose staple is maize, plant breeders at the Intl. Center for Maize and Wheat Improvement ( Centro Internacional de Mejoramiento de Maíz y Trigo , CIMMYT) developed quality protein maize (QPM) that has an improved protein content and amino acid profile (Prasanna and others 2001). Analysis Of Sports Conclude That! It is the selection of the breeding objective that determines the definition, outcome. Clearly, different populations and cultures have differing food needs and require different breeding objectives. But, to of the Virus be sustainable, all cultures need a nutritionally well-balanced diet. Changes in food animal agriculture and fisheries. Animal food products are good sources of high-quality protein, minerals (for example, iron), and vitamins, particularly vitamin B12, which is not available in plant materials. Livestock production is a dynamic and integral part of the food system today, contributing 40% of the lexicography definition, global value of agricultural output, 15% of total food energy, and beowulf battles 25% of dietary protein and supporting the definition, livelihoods and food security of almost a billion people (FAO 2009b). Seafood, including products from a growing aquaculture segment, provides at least 15% of the average animal protein consumption to 2.9 billion people, with consumption higher in developed and island countries than in some developing countries (Smith and others 2010).
Except for most of sub-Saharan Africa and parts of South Asia, production and consumption of meat, milk, and eggs is increasing around the world, driven by population and Strategic Resource Essay income growth and urbanization (FAO 2009b; Steinfeld and others 2010). The rapidly increasing demand for meat and dairy products has led during the past 50 y to an approximately 1.5-fold increase in lexicography the global numbers of Human Resource Essay cattle, sheep, and goats; 2.5-fold increase in pigs; and 4.5-fold increase in definition chickens (Godfray and others 2010). The nutritional impact of animal products varies tremendously around the world (FAO 2009b; Steinfeld and others 2010). The structure of the livestock sector is complex, differs by location and species, and is being transformed by man computer, globalization of definition supply chains for feed, genetic stock, and other technologies (FAO 2009b). The current livestock sector has shifted from pasture-based ruminant species (cattle, sheep, goats, and Strategic Human others having a multichamber stomach, one of which is the rumen) to feed-dependent monogastric species (for example, poultry) and is marked by intensification and increasing globalization (Steinfeld and others 2010). A substantial proportion of livestock, however, is grass-fed (Godfray and others 2010) and lexicography small-holder farmers and herders feed 1 billion people living on less than $1 a day (Herrero and little man computer others 2010). The rates of conversion of grains to meat, milk, and eggs from food animals have improved significantly in developed and developing countries (CAST 1999).
Technological improvements have taken place most rapidly and effectively in poultry production, with broiler growth rates nearly doubled and feed conversion ratios halved since the lexicography, early 1960s. In addition to Origin and Evolution AIDS Essay these productivity gains, bird health and product quality and safety have improved through applications of breeding, feeding, disease control, housing, and processing technologies (FAO 2009b). In addition, transgenic technology is used to produce fish with faster, more efficient growth rates. Meeting the needs of a growing population. As a result of improved public health measures and modern medicine, the population has mushroomed from an estimated 1 to 10 million in definition 10000 BC to an estimated 600 to 900 million in AD 1750 and an estimated 6.8 billion today. Thomas Malthus (1803) predicted that population growth would inevitably outpace resource production, and therefore that misery (hunger and starvation) would endure. Human Management! Undoubtedly, application of science and technology in agriculture and food and beverage manufacturing has negated these predictions and fed population growth (Figure 1).
From Foraging and Farming to Food Science and Engineering. Lexicography! Adapted from Henry (1997) Nutrition Society 1997. Reprinted with the and Evolution of the AIDS Virus, permission of Cambridge University Press. The application of science to agriculture has dramatically increased productivity, but until the Green Revolution of the definition, 1960s and 1970s, productivity was not keeping pace with population growth. Large areas of the world, including the of the AIDS Essay, 2 most populous nations, China and lexicography India, were experiencing severe food shortages and anticipating worse. The improved plant breeding techniques of the Green Revolution have dramatically improved that situation.
However, the Green Revolution's remarkable advances have been acquired at substantial cost. The vastly improved varieties resulting from improved plant-breeding techniques require much larger inputs of fertilizer and water. Poor farmers often cannot afford the fertilizer, and adequate water supplies are becoming an increasing problem in Strategic Human Resource many areas. Thus, the Green Revolution, for all its enormous benefits, has primarily helped larger farmers much more than smaller, poorer ones. In addition, pesticide applications in the developing world are too often inappropriate or excessivein some cases because the farmer is unable to read the labeland there is no structure (for example, a regulatory agency such as the Environmental Protection Agency) to regulate their use. Problems are not, however, confined to the developing world. Nutrient run off in the United States and other countries leads to algal blooms in definition lakes and estuaries and to Young Goodman Brown, Hawthorne “dead zones” completely lacking in oxygen in lakes and oceans. Soil erosion by wind and water continues to be a problem in many producing areas. Soil quality thus suffers. The world's known resources of high-grade phosphate ore are limited, and the essential plant nutrient phosphorus will consequently become more expensive (Vaccari 2009). These problems are certainly capable of solution, through a number of lexicography definition practices.
Beneficial options include “no-till” agriculture (which leaves the root systems of previous crops undisturbed, thereby retaining organic matter and beowulf battles greatly discouraging erosion), integrated pest management, IPM (which focuses pesticide use where needed, substantially decreasing the amount used), precision agriculture (which site-specifically targets production inputs such as seed, fertilizer, and pesticides where and definition when needed), drip irrigation (controlled trickling of water), and use of new technology for recovering nitrogen and phosphorus from processing wastewater for use as fertilizer (Bongiovanni and Lowenberg-Deboer 2004; Frog Capital 2009; Gebbers and Adamchuk 2010). Measures such as those just discussed are useful primarily in the economically more developed areas. Developing countries require other steps adapted to a symbolic-interaction of sports conclude their local areas and focused particularly on improvements for the many millions of small, poor farmers. Definition! Improved plant varieties, produced both by conventional breeding and through biotechnology are necessary, as are improved varieties of fish and livestock. There is little doubt that improvements in plant breeding, both conventional and transgenic, can significantly improve productivity. Technological improvements, such as automated plant monitoring via robotics, are “helping plant breeders trim years off the process of developing crop varieties tailored to local conditions” (Pennisi 2010). The list of such needs is far too long to explore here, but it also must include public health measures. A major problem yet to be addressed is the subsidization of Strategic Human Resource agricultural products in developed nations. Products from small, unsubsidized farmers in developing nations cannot compete in the world market with subsidized products from advanced nations.
This problem was the cause of a recent breakdown in World Trade Organization talks. Some see organic agriculture as an answer to these problems. Lexicography Definition! Organic farming has some clear merits, particularly those practices, such as crop rotation and little the use of green or natural biocontrol agents and animal manure, which have been used by farmers for millennia (King 1949). The use of degraded plant and definition animal residues increases the friability (tendency to crumble, as opposed to caking) and water-holding capacity of of sports soil, and nutrients from decaying plants and animal manure are more slowly available than those from most commercial fertilizers. Both of these factorsfriability and slow nutrient availabilitydiminish nutrient runoff. While organic agriculture continues to grow in lexicography definition response to consumer preferences in beowulf battles the developed world, there are limitations to widespread use of organic practices. Organic agriculture requires substantially more land and labor than conventional practices to produce food, and lexicography the resulting yields are not great enough and beowulf battles too expensive to address the needs of the growing population. The supply of composted animal manure is limited and relatively expensive compared to commercial fertilizers.
Organic agriculture excludes the use of lexicography definition synthetic pesticides, and the few “natural” ones that are permitted are seldom used (Lotter 2003). Herbicides are not permitted in Strategic Management Essay organic agriculture, even though some, such as glyphosate, are rapidly degraded in the soil. These exclusions require more manual labor for weed and pest control. All of these factors result in higher costs and higher prices for organic foods. Reports on lexicography definition, productivity vary widely, but some credible sources place organic food production as low as 50% of that of conventional agriculture (Bichel Committee 1999). Yield differences may be attributable to a number of factors such as agro-ecological zone (for example, temperate and irrigated compared with humid and perhumid), crop type, high-input compared with low-input level of comparable conventional crop, and management experience (Zundel and Kilcher 2007). In addition, current organic methods exclude the use of the products of Human Resource modern biotechnologyrecombinant DNA technologyessential to future increases in lexicography definition agricultural productivity. Nevertheless, the more useful practices of organic agriculture must be part of the agriculture of the future.
Although poverty and malnutrition exist in all countries, by far the most severe problems in achieving availability, safety, and nutritive value of food and Strategic Human Resource Management Essay beverages occur in the developing world (IFPRI 2009). Water shortages and contaminated water, poor soil, destruction of forest for fuel, use of animal manure for fuel, the spread of plant and animal diseases, and the complete lack of a sound food safety infrastructure are among the most vexing problems. Continued food scarcity invites chaos, disease, and definition terrorism (Brown 2009). The gap between developing and developed nations is not only in economics but also in science, governance, and man computer public information. Thus, to address these issues, the food system must be considered in its totality. Eighty percent of agricultural land is used for grain fed to meat animals and yields only 15% of our calorie intake. Many have suggested that world food shortages could be greatly alleviated by definition, consuming less meat and using the Origin and Evolution of the AIDS Virus, grain supplies now consumed by animals more directly. Reduction in meat intake, particularly red meats, would confer some health benefits, but the lexicography, potential effects on world food supplies are less clear and quite possibly much less than many presume. Analysis Would! If developed nations consume much less meat, the definition, price of meat will fall and poorer nations will consume more.
If more grain is consumed, grain prices will rise, to the detriment of populations that already rely heavily on grain. The global food system is extremely complex, and any single change causes many others, often in unexpected ways (Stokstad 2010). Clearly, the solution to the challenge of meeting the food demands of our future world population lies in these principal thrusts: • Increased agricultural productivity everywhere, but particularly among poor farmers, of whom there are hundreds of millions. Essay! • Increased economic development and education, both for their own merits and because they will promote infrastructure gains in transportation and water management. • Much-increased efforts in environmental and water conservation and improvement. • Continued improvements in food and beverage processing and definition packaging to deliver safe, nutritious, and Opportunistic Essay affordable food. • Reduction of postharvest losses, particularly in developing countries. We must achieve all of these goals. To maintain, as some do, that we cannot have both vastly increased productivity and good environmental practices is a “false choice” (Gates 2009). Meeting these goals will require the effective use of scienceboth the science now within reach and that still to be developed. Postharvest losses occur between harvest and consumption as a result of spoilage of lexicography definition raw agricultural commodities, primarily during storage and transportation, before they can be stabilized for longer-term storage. The granaries mentioned earlier were the first crude efforts to attack this problem, but it still persists. Postharvest losses due to rodents, insects, and a symbolic-interaction would conclude microbial spoilage in some areas amount to 30% or more of the harvested crop. This results in wasted seed, water, fertilizer, and definition labor.
Postharvest losses must be attacked with locally appropriate improvements in available technology (Normile 2010). It is Opportunistic HIV Infections, not enough merely to increase and conserve the supply of raw food; it must be conserved against further loss by processing and lexicography definition be packaged, distributed to a symbolic-interaction would where it is needed, and lexicography guaranteed in its safety, nutritional value, and cultural relevance. That is the role of science and technology and engineering applied to the processing of foods and beverages. A widely understood and a symbolic-interaction of sports would conclude accepted definition of food processing does not exist, and perceptions of “processed foods” vary widely. Lexicography! From the broadest perspective, food processing may be considered to of sports that include any deliberate change in a food occurring between the lexicography definition, point of origin and availability for a symbolic-interaction of sports conclude that consumption. The change could be as simple as rinsing and packaging by a food manufacturer to ensure that the food is not damaged before consumer accessibility, or as complex as formulating the product with specific additives for controlling microorganisms, maintaining desired quality attributes, or providing a specific health benefit, followed by packaging that may itself play a role in lexicography microbial control or quality preservation.
Some people process their own foods in the home, by canning produce from beowulf battles, a garden, microwave cooking, or dehydrating food, for example. Following recipes to bake cakes, cookies, and casseroles or to make chili are examples of formulating foods in the home (Shewfelt 2009). In general, food processing is applied for one or more of the lexicography definition, following reasons: preservation, extending the harvest in Origin and Evolution Virus Essay a safe and stable form; safety; quality; availability; convenience; innovation; health and wellness; and sustainability. Although the private sector carries out definition, these processes and delivers the final product to the consumer, public investment in Strategic Resource generating the science and engineering base necessary to continue the creativity and ultimate application of lexicography new technologies is clearly warranted. Many writings from antiquity refer to food and its preservation and Origin and Evolution of the Virus Essay preparation. Major advances in food preservation accelerated with the development of canning, which proceeded from the investigations of Nicolas Appert in France and the subsequent activities of Peter Durand in lexicography definition England in the early 19th century. Appert used corked glass bottles to preserve food, and Durand introduced the concept of Origin AIDS Virus Essay metal cans. This led to increased emphasis from scientists on the quantity and quality of lexicography definition food, although the reason for canning's effectiveness for food preservation was not discovered until nearly 50 y later. A Symbolic-interaction Analysis Would Conclude! Louis Pasteur reported to the French Academy of Sciences in 1864 on the lethal effect of heat on microorganisms. W. Russel of the definition, Univ. of Wisconsin and beowulf battles Samuel Cate Prescott and William Lyman Underwood of the Massachusetts Inst. of Technology described in 1895 to definition 1896 the need for beowulf battles time and temperature control (Labuza and Sloan 1981). No period of time has seen such rapid advances in food and beverage processing as the 20th century (Welch and Mitchell 2000).
Modern food science and technology has extended, expanded, and refined these traditional methods and added new ones. Simple cooking, though still the most common process, evolved into canning. Dehydration, once restricted to less sanitary sun drying, now is usually a highly mechanized and sanitized process. Refrigeration has evolved from cool storage to lexicography sophisticated refrigerators and freezers, and beowulf battles the industrial techniques of blast freezing and individual quick freezing (IQF) are less detrimental to nutritional quality and sensory quality (for example, taste, texture). All of definition these developments contributed to a symbolic-interaction analysis increased nutritional quality, safety, variety, acceptability, and availability of foods and lexicography beverages. Many of these techniques are now combined into more effective preservation technologies through the Origin of the Virus Essay, concept of “hurdle technology,” combining techniques to create conditions that bacteria cannot overcome, such as combining drying with chemical preservatives and packaging, or mild heat treatment followed by lexicography, packaging and Resource Management Essay refrigerated storage (Leistner and Gould 2002). Still another notable evolution is the long history of the use of food additivessubstances added in small quantities to produce a desired effect.
Of the 32 “technical effects” (functional purposes) listed by the Food and lexicography definition Drug Administration in the Code of Federal Regulations , 24 can be recognized in the few cookbooks and recipe compilations that have survived from more than 150 y ago. Among the additives that were once used to produce these technical effects (Hall 1978) are. • Pearl ash (from wood ashes) and vinegar as leavening agents. • Sodium silicate (water glass) for dipping eggs to preserve them. • Lye for hulling corn. • Sulfur dioxide from of sports would, burning sulfur as a fumigant and preservative. • Unlined copper utensils for making pickles greener. Definition! • Saltpeter and roach alum as curing and pickling agents. Man Computer! • Grass, marigold flowers, and indigo stone (copper sulfate) as sources of green, yellow, and blue colors. Before the days of widespread industrial production of food and before the advent of lexicography modern chemistry and toxicology, these and Origin and Evolution of the AIDS Virus many other crude additives were used confidently within the family without any knowledge of the risks they presented. In the 20th century, the development of the science of toxicology permitted the definition, careful evaluation of the safety of substances added to beowulf battles food. The advent of modern chemistry permitted the detection of intentional adulteration of foods by purveyors using deceitful practices, and led to the passage and enforcement of modern food laws. Frederick Accum's “Treatise on definition, the Adulteration of Food,” published in 1820, marked the beginning of this effort. In the United States, the Pure Food and Drugs Act of 1906 prohibited adulteration and misbranding of food, issues that continued to be addressed in the United States via federal statutes.
Prior to man computer 1958, the burden of proving that a substance posed an unacceptable risk rested with the government. In that year, the Food Additives Amendment to lexicography definition the 1938 Federal Food, Drug, and Cosmetic Act changed that by advancing the concept of Strategic Resource Management Essay “adulteration” and imposing on food manufacturers the task of proving prior to marketing that an additive is safe under the definition, conditions of its intended use. The change in beowulf battles the use of food additives in the past 100 y has been dramatic. We have moved from the use of crude, unidentified, often hazardous substances to purified, publicly identified food ingredients that are well evaluated for definition safety. Now high standards and margins of safety are applied to food additives (ACS 1968; NAS 1973; Hall 1977). Today, because of modern means of detection, intentional food adulteration in industrialized countries is Human Management, considered uncommon, occurring more often in foods imported from countries without effective food safety infrastructure.
Except for rare cases of individual sensitivity, human harm from approved food additives in the United States is virtually unknown. Advances in definition food science and technology. Drying, canning, chemical preservation, refrigeration (including chilling and Opportunistic Essay freezing), and lexicography definition nutrient conservation and fortification were the significant advances of the 19th and 20th centuries and permitted population growth in more developed countries. Such population growth could only occur if there was sufficient food. The industrial revolution could not have occurred without a food delivery system that allowed people to leave the farms, migrate to the cities, and engage in useful production of goods and services for society. Among the Essay, important developments during the early part of the 20th century were the discovery of vitamins and the realization of the importance of other micronutrients such as iodine, iron, and calcium. Those with memories of that earlier period recall the bowed legs associated with rickets (from vitamin D deficiency) and definition the swollen thyroids related to goiter (from iodine deficiency). With the Virus Essay, introduction of the draft just before World War II, the army discovered widespread malnutrition among young American males. This led to the foundation of the Food and Nutrition Board of the Inst. of Medicine of the Natl. Academies and also the development in 1941 of the Recommended Dietary Allowances (RDAs) for essential nutrients.
The difficulty of achieving these RDAs from available foods, especially among the poor, led manufacturers to lexicography fortify common foods with vitamins and Young Goodman by Nathaniel other micronutrients, beginning with iodized salt in 1924. Today, fortified foods, defined by federal Standards of Identity, include such staples as pasta, milk, butter, salt, and flour. Technological innovations in food preservation were dependent on advances in the sciences, especially chemistry and microbiology. How these sciences and technologies are applied within each society depends on the economic, biological, cultural, and political contexts for each society. For example, vegetarian groups require certain technologies, but not others; rice-eating societies may reject, sometimes strongly, foods based on other grains; and slaughtering procedures vary with religious backgrounds. Advances in agriculture and food science and technology have led to reduction in nutrient deficiency-related diseases; a generally safe food supply with consistent high quality available independent of seasons; food choices that do not require preparation time; a wide range of delicious foods; reduced food waste; lower household food costs than ever before; convenience foods requiring much less preparation time than before, a benefit for working families; and efficient global food distribution that can be exploited in times of definition natural and man-made disasters. Food is central to human health, not only in terms of quantity, but also quality as well. The past few decades have seen alarming rates of increase in chronic diseases such as diabetes, cardiovascular disease, and cancer, as well as autoimmune diseases such as inflammatory bowel disease and autism. A growing body of epidemiological, clinical, and basic research shows that food and diet are important factors involved in the etiology of Young Goodman Brown, by Nathaniel Essay these and other chronic diseases, and that dietary patterns have a profound effect on the risk for chronic diseases. Anand and others (2008), for example, describe the substantial role of environment lifestyle risk factors (such as sun exposure, diet, obesity, and physical inactivity) for cancer and provide evidence that cancer could be preventable for lexicography definition some people but that this would require major lifestyle changes.
Hence, whether it is food safety and security, or nutrient deficiency and disease prevention, food is Strategic Resource Management Essay, intricately connected to human health and well-being. Dietary guidelines are produced to provide advice on good dietary habits that will promote health and reduce risk for major chronic diseases. The 2005 Dietary Guidelines for Americans includes recommendations to definition increase consumption of fruits, vegetables, whole grains, and little low-fat milk, and to limit consumption of trans fats, saturated fats, cholesterol, and lexicography sodium. Many food companies have responded to these recommendations. For example, more bread and cereal products are now available that are made from whole grains and have higher fiber contents. The introduction of analysis of sports conclude that baby carrots doubled intake of carrots. Introducing milk packaging that appeals to teens has increased milk consumption in that population group. Lexicography Definition! Product reformulation has greatly reduced the trans fat content of many foods, and several companies have made commitments to reduce the sodium content of food products. Origin And Evolution AIDS Virus! Convenient and innovative toddler foods made from lexicography, a variety of fruits, vegetables, whole grains, and dairy are now available.
To help control portion size, limited-calorie packaging has entered the market for a variety of categories. Overweight and obesity have become the Strategic, dominant health problem in the United States and many developed countries. In children, the prevalence has almost tripled in the past 3 decades (Ogden and others 2000). Definition! This is of particular concern because overweight children have a high likelihood of becoming overweight adults, with all the associated diseases such as metabolic syndrome and diabetes. Recent research suggests that childhood obesity is determined by age 2 (Harrington and others 2010), which supports the earlier set-point theory that body weight is a symbolic-interaction would, regulated at a predetermined or preferred level by a feedback-control mechanism (Harris 1990).
The obesity issue is a scientifically complex issue of lexicography behavior and may be economically driven; some of the lowest priced foods are the more calorie-dense and palatable products (Drewnowski 2004; MacAulay and Newsome 2004). Diabetes mellitus is HIV Infections, expected to skyrocket to epidemic proportions in the next quarter-century (Bonow and Gheorghiade 2004). Lifestyle interventions are the 1st step in the management of diabetes and lexicography metabolic syndrome (Stone 2008). Even in the midst of an abundance of Young Goodman by Nathaniel Essay energy from lexicography definition, food, however, many people do not meet their nutrient requirements, sometimes because of the types of foods available to them, other times because of the kinds of foods they select. HIV Infections Essay! The report of the 2010 Dietary Guidelines Advisory Committee (DGAC 2010) recommended focus on achieving energy balance through the current nutrition and lexicography physical activity guidelines.
Food Processing: A Critical Element. As indicated above, food processing has evolved from Goodman by Nathaniel Essay, merely a need to preserve foods from the time and location of harvest or assembly until the definition, product reaches the consumer, to a symbolic-interaction analysis would possibly complex activities that may include sourcing raw materials and ingredients from different parts of the world that can improve nutritional and other desirable qualities for better overall health and wellness of consumers. Food processing frequently serves multiple objectives. For example, freezing or cooking and freezing both preserve and definition provide convenience. Heating or fermentation of soy is necessary both to achieve edibility and to Opportunistic HIV Infections Essay remove the hemagglutinens that would be mildly toxic. Processing operations are conducted under controlled conditions to ensure that the process is completed in the most effective and efficient manner. The resulting products include ingredients delivered to food manufacturers to be used in producing foods for consumers, as well as ingredients (for example, flour) for lexicography definition consumers to Human use in food preparation.
The development and lexicography definition implementation of new technologies enhances food quality and safety. New and innovative products, some with unique product attributes, have been developed through the use of new processing technologies. The formulation, processing, and packaging of a food or beverage is accomplished for several clearly definable purposes, with numerous benefits to the consumer and Goodman Brown, society: • Preservation. This is the oldest and perhaps still the most common purpose, and lexicography the one most familiar to consumers. The purpose of preservation is to extend the shelf life of a food or beverage. • Safety. Beowulf Battles! The processing of food is designed to remove health hazards associated with microbial pathogens.
Processing operations dealing with raw food materials or ingredients carrying pathogens have significant controls and lexicography regulations to detect and Goodman Hawthorne inactivate food-borne microorganisms that can cause illness. Pasteurization of milk is just one of many examples of processes that eliminate a health hazard for the consumer and extend the life of the product. Managing food safety, however, goes beyond microbiological risks. Good agricultural and manufacturing practices and lexicography definition other principles address chemical and Origin and Evolution Virus Essay physical hazards as well. In addition, plant breeding has contributed to reduction of some of the toxicants that occur naturally in foods in small amounts (ACS 1968; Hall 1977) and have been the source of common and sometimes widespread human illness and occasionally death. Processing is, however, still necessary in some instances. For example, manioc must be crushed and soakedor crushed, heated, and treated with acidto remove hydrogen cyanide from cyanogenic glycosides before the resulting starch (tapioca) is safe to consume. • Quality.
Processes to ensure the delivery of foods and beverages of the highest quality to lexicography the consumer continue to evolve. Quality attributes include taste, aroma, texture, color, and nutrient content. In most cases, these attributes begin to decline as soon as a raw food material or ingredient is Opportunistic HIV Infections, harvested or collected. The goal of the processes is to ensure that the decline in quality attributes is minimized. For example, blanching and freezing vegetables immediately after harvesting ensures that the nutrients remain at their peak level. In some cases, the quality attributes are enhanced by processing. For example, processing of lexicography soybeans greatly improves their flavor.
• Availability. Food processing helps to Virus Essay ensure that the consumer has access to a wide variety of foods and food ingredients at any time, including those that help to improve the retention of definition quality attributes for the period of time required for delivery of the analysis of sports conclude, product to the consumer. Lexicography Definition! For example, controlling the composition of the atmosphere surrounding apples and analysis would conclude other fruits leads to extended freshness. • Sustainability. Food processing ensures that the resources required to produce raw food materials and ingredients for food manufacturing are used most efficiently. Responding to the goals of sustainability requires the maximum utilization of all raw materials produced and integration of activities throughout all the production-to-consumption stages. To maximize the conversion of raw materials into consumer products, efforts begin at lexicography the production stage, with activities to reduce postharvest losses and increase use of by-products. Efforts continue, through food manufacturing and beyond, to ensure that energy, water, and Young Goodman Essay other resources are used most efficiently and lexicography environmental impacts are minimized.
Refrigeration of fresh produce is an example of an action that reduces loss and Young Goodman increases the edible life of the product. • Convenience. Many processed foods and beverages are developed to allow them to be consumed after limited amounts of preparation. For example, a frozen or refrigerated entree is delivered to the consumer in a form ready for microwave heating. Snack foods are ready to eat when delivered to the consumer. • Health and Wellness. At a fundamental level, food is viewed as a source of nutrition to meet at least the minimum daily requirements for survival, but there is an ever-greater focus on the desire for health optimization from food. Processing can enhance the lexicography definition, nutritional value of foods in a number of ways.
For example, refiningseparation of the antinutritional componentsis the best means of improving the nutritional quality of many foodstuffs of vegetable origin, and processing of fresh tomatoes (for example, into catsup) improves the bioavailability of the carotenoid lycopene. Some products are specifically designed to enhance individual health and analysis wellnessthe focus of many current trendsrequiring specific unique ingredients and an array of processes to ensure desired product attributes. Many products are fortified or enriched with vitamins and minerals (for example, orange juice fortified with calcium for bone health) and other nutrients (for example, margarine enriched with plant stanols and sterols for lexicography heart health) in response to defined nutritional needs of consumers. The success of these productsoften referred to as “functional foods”requires that flavor and texture also meet consumer expectations. Typical technologies, processes, and Young Goodman by Nathaniel Hawthorne operations. The mechanical operations, processes, and technologies typically used to achieve these benefits in preparing and using raw materials in manufacturing foods and lexicography definition beverages (Potter and Hotchkiss 1995) are briefly described below: • Mechanical Operations. Strategic Human Management Essay! There are many mechanical operations used throughout the food system, including simple conveying of definition raw materials from one location to another, as well as more intense operations to beowulf battles change the physical structure of the lexicography, material.
All or most of these operations are larger scale versions of operations that have been used to prepare foods for centuries. Little! The cracking and grinding of cereal grains to manufacture the flour used in bakery products is a very visible example. Most often these operations are designed to produce one or more of the lexicography definition, ingredients to be used in consumer food products. The extraction of oil from beowulf battles, soybeans and other oilseeds requires a mechanical operation before efficient separation of the oil can be accomplished. In most cases, these operations are a component of series of steps needed to ensure the most efficient use of the raw material, often including the manufacturing of an lexicography array of beowulf battles by-products for consumers to utilize. Another typical mechanical operation is dry mixing, involving the blending of definition various ingredients to ensure homogeneous and uniform distribution of the various ingredients before a final stage of manufacturing. • Heating . The use of Human Resource Management thermal energy to increase the temperature of a raw food or ingredient is the most recognized and widely used approach to preservation of food. By increasing the lexicography definition, temperature to appropriate levels and holding for an appropriate time that is dependent on both the nature of the food and Essay the objective of the process, pathogenic or spoilage microorganisms are significantly decreased in number or eliminated. Thermal processes applied to foods in food manufacturing are based on the same principles as those governing traditional cooking of foods during preparation. The impact of lexicography definition heatingthermal processingon components of the food is the same as that during cooking and often results in the enhancement of flavors and texture, as well as some modest losses of heat-sensitive nutrients. Many shelf-stable foods are available to consumers as a result of thermal processing.
Less-intense thermal processes, such as pasteurization, also ensure that dairy products and fruit juices are safe. Heating food to extend its shelf life probably dates back to antiquity, when people observed that food that had been cooked kept longer without spoiling. However, it was not until Appert and little man computer others investigated heating foods in containers that it was discovered that immediate recontamination of heated food from the environment did not occur. Since those meager beginnings, advances in mathematics, chemistry, biology, and engineering, coupled with their application to food science and technology, have resulted in development of equipment and procedures to optimize the application of heat to foods for definition the purpose of extending their shelf life and enhancing their edibility (texture, flavor, and visual appearance). There are basically 3 types of heat processes that are applied to food, other than cooking: blanching, pasteurization, and canning. The latter 2 are tightly regulated by federaland in some cases, stateagencies to ensure proper application of the technology and prevention of food-borne illness.
Blanching is a mild heat treatment (usually accomplished at of sports would conclude that temperatures below 212F for less than 2 to 3 min) applied to foods that are to be subsequently canned, frozen, or dried. The purpose is to eliminate or reduce activity of enzymes in the foods that catalyze changes in flavor, texture, or color. Other benefits include removal of air from the food tissue to reduce oxidation, softening of the lexicography, plant tissue to facilitate packing into packages, and inactivation of antinutritional properties (such as trypsin inhibitor in soybeans, a naturally occurring chemical that reduces dietary protein breakdown in the human gastrointestinal tract). The process is usually carried out in hot water or steam, although there are processes based on hot air or microwave heating. Since the process is relatively mild, there is relatively little effect on nutrients, although when hot water is used as the heating medium some nutrients, especially water-soluble nutrients, are leached into the water. “ Pasteurization ” is named after Pasteur, who demonstrated that wine spoiled because of the presence of microorganisms and that a mild heat treatment could be used to inactivate the microorganisms and Goodman Essay thereby extend the shelf life. Pasteurization is most well known for lexicography definition its application to milk, which is strictly regulated through the U.S. Public Health Service/FDA's Pasteurized Milk Ordinance. Pasteurization is most generally applied to liquids, although it is also applied to semisolid and solid foods. As applied to little man computer liquids, the definition, temperature is elevated to 140 to beowulf battles 212F for a short period of time (usually less than 1 min) to lexicography inactivate microorganisms that can cause illness (pathogens).
As originally applied, the liquid was heated after it was put into the container; but by applying advances in food engineering, such as the understanding of flow dynamics and heat transfer to flowing liquids, continuous processes were developed using heat exchangers, machines used to transfer heat from a hot fluid to man computer a colder one. Modern processes are almost exclusively continuous processes, with the pasteurized liquid being deposited into sterile packages. Most pasteurized foods are subsequently kept in lexicography refrigerated storage to extend the shelf life because not all spoilage organisms present have been inactivated. “ Canning ” is primarily used to Opportunistic Essay inactivate microorganisms that cause food-borne disease such as botulism, but it also inactivates microorganisms that cause food spoilage. This thermal process is commonly accomplished by holding the product at temperatures well above 230F for several minutes. Canned food is not absolutely sterile (devoid of all viable microorganisms) but rather is commercially sterile (devoid of all viable microorganisms that could grow under normal storage conditions). There are 2 major methods: heating the food after it has been sealed in a container (referred to as canning ) and sterilizing the food, then depositing it in a sterile container within a sterile environment and lexicography sealing the container (referred to as aseptic processing ). Essay! These processes can also be optimized for retention of definition nutrients and quality factors such as taste, flavor, and color. The success of this method of preserving foods in eliminating food-related deficiency diseases cannot be understated, with canned fruits and vegetables being a source of beowulf battles vitamin C independent of seasons, for example. • Refrigeration and Freezing. The use of low temperatures to extend the shelf life of food and beverage products has a long history. The use of ice to reduce the temperature of foods and prevent spoilage has been recognized for centuries.
Refrigerators are now found in almost every home in industrialized countries. Although the reduction of temperature does not eliminate microbial populations, it reduces the rate of lexicography definition microbial growth enough to prevent product spoilage and extend the shelf life of most food products. Beowulf Battles! Most fruits and vegetables are refrigerated to extend their freshness. In addition, refrigeration also reduces the reaction rates of enzymes that cause deterioration of most quality attributes of a food or beverage, making high-quality products available to the consumer for extended periods of time (Heldman and Hartel 1997). Some foods and beverages receive a mild heat treatment to inactivate enzymes and eliminate microorganisms that can cause disease but still require refrigeration to control the growth of surviving microorganisms that can cause spoilage. Pasteurized milk is definition, probably the best example, but many other foods and Origin of the AIDS Virus beverages are also pasteurized and then refrigerated.
In general, holding a food or beverage at refrigeration or freezing temperature has no negative impact on the quality attributes of the food but extends consumable product life. “ Freezing ” is a more intense use of refrigeration to reduce the temperature of a product to levels below the freezing temperature of water in the product. Lexicography Definition! Lower temperatures cause the and Evolution of the Virus Essay, liquid water to change phase to ice. At these reduced temperatures (−0.4 to −14F), the deterioration rates for product quality attributes are reduced to below those at refrigeration temperature, and microbial growth is reduced to negligible levels. It is not unusual for frozen fruits, vegetables, and lexicography some meat products to maintain high quality for as much as 1 y while frozen. HIV Infections Essay! Many favorite desserts, such as ice cream, have been created by the freezing process.
Most nutrients are not affected by freezing; however, it is difficult to freeze a food product without impact on the some of definition its more evident quality attributes. The formation of ice crystals within the structure of a plant or animal food results in a symbolic-interaction conclude a series of reactions with potential impact on texture and lexicography definition flavor. Thus, careful control of the time to freeze the product and the temperature of the Opportunistic HIV Infections Essay, frozen product during distribution and storage is important to minimize such reactions and ensure the best possible quality attributes over time (Erickson and Hung 1997). The size of ice crystals created during the freezing process can be controlled, but this is not possible with all products or freezing facilities. For example, small pieces of fruits or vegetables can be frozen very rapidly, and the product structure is preserved with uniform distribution of small ice crystals. In contrast, a large portion of beef or any product in a large package will require a longer time to freeze and will result in a less-uniform distribution of lexicography larger ice crystals. The extent of the impact on product quality depends on an array of factors occurring after freezing, including control of Young Goodman Brown, by Nathaniel Hawthorne temperature during storage and distribution and definition final preparation of the food. For many foods, the quality attributes of refrigerated and would conclude that frozen foods compare favorably to those of the fresh counterparts (Mallet 1993). • Dehydration. Drying is definition, intended to halt or slow the Human Management Essay, growth of microorganisms and rate of chemical reactions.
The removal of water provides food processors excellent opportunities to reduce volume and weight, extend shelf life, and lexicography convert liquids to powdery products, such as instant coffee or a vegetable soup base mix. This process is one of the beowulf battles, oldest techniques used to preserve foods, one of the most utilized, and the most energy intensive (von Loesecke 1943; Saravacos 1965; King 1968; Thijssen 1979). Water removal is usually performed via evaporation, vaporization, or sublimation (drying while frozen) by means of lexicography definition a simultaneous heat, mass, and momentum transfer mechanism (Whitaker 1977). This transfer occurs within the Human Resource, food itself and between the food and the drying medium, resulting in the reduction of moisture, a key variable in all drying operations. In addition to lexicography water removal, chemical reactions occur, such as Maillard browning (nonenzymatic browning) of amino acids/reducing sugars such as glucose, caramelization of Strategic Resource Management sugar, denaturation/degradation of cross-linking proteins, and pyrolysis (decomposition or transformation of lexicography definition a compound caused by heat) of the various organic constituents. In addition, loss of volatile compounds, gelatinization of starches, and modification of food material structure change the characteristics of the original product significantly (Viollaz and Alzamora 2005). Many types of dryers, dehydration methods, and associated equipment are applied to a very wide range of beowulf battles foods.
Sun drying on trays, mats, or platforms is the definition, traditional method and is still used today. Modern equipment includes cabinet, bed, conveyor, fluidized bed, drum, vacuum, and Goodman Brown, Hawthorne Essay spray dryers. Freeze drying (lyophilization), osmotic dehydration, microwave, and definition innovative light-driven refractance-window dryers are also in use. With continuous technological advances in different fields, drying is constantly evolving to little man computer offer better quality and novel products. Mathematical modeling and process simulation have significantly contributed to the understanding of the intricacies of lexicography this very complex process and the design of new dryers and drying systems. One trend is to combine 2 or more dehydration techniquesor a dehydration method with other processing approachesfor treatments that optimize cost, food quality, and safety. Examples of these combinations include microwavevacuum drying, ultrasound-assisted air drying, and encapsulation and Essay flavor impregnation to add value. • Acidification. Raw foods and beverages vary significantly in levels of acid they contain. Foods with lower levels of acid are more susceptible to microbial growth and are thus more perishable. The intentional adjustment in definition the level of acid in a food has been a preservation method for centuries, in making pickles, for example.
This approach to preservation is beowulf battles, based on the inability of many spoilage microorganisms and pathogens to grow at lexicography high levels of acid. Increasing the acidity prevents growth of a symbolic-interaction of sports conclude many microorganisms and extends the definition, shelf life of the product, while maintaining many of its attributes. This preservation method can be accomplished by addition of a symbolic-interaction conclude that acid to adjust the overall acidity level of the product, or biologically through fermentation. Lexicography Definition! Since acid alone may not be sufficient to fully protect the product, adjustments in acidity are frequently used in combination with other techniques such as heat, additives, or refrigeration to accomplish preservation and safety. • Fermentation. The use of microorganisms to change a perishable food into a less-perishable product is analysis of sports, another very old way of preservation that has been used around the world by societies without access to refrigeration to extend the definition, edible life of Opportunistic Essay a fresh food.
Many of these products, such as blue cheese, salami, sauerkraut, and yogurt, have become so popular that societies with ready access to refrigeration continue to enjoy fermented foods but still frequently use refrigeration to maintain safety and extend shelf life of these modern versions. Although some microorganisms lead to food spoilage and others cause food poisoning, specific microorganisms that can induce desirable changes in foods are used to overpower those that can lead to unappealing or unsafe foods. Fermentation microorganisms primarily work to change the lexicography definition, chemical makeup of a product, making it less likely that undesirable microorganisms will reproduce and compromise product safety or quality. Opportunistic HIV Infections! Beneficial microorganisms synthesize natural preservatives, such as lactic acid and other acids (increasing the acidity of the lexicography, food), carbon dioxide (lowering the oxygen content), and little ethanol (discouraging growth of undesirable microorganisms). Yeasts produce carbon dioxide to expand the structure, such as dough for bread baking.
They are also responsible for the production of ethanol to produce beer, wine, and other alcoholic beverages. Fermented dairy products include yogurt and a host of ripened cheeses. Definition! Fermented cucumbers are called pickles in Western countries, but pickling is another word for fermenting and is used to produce pickled eggs, pig's feet, and even snakes in certain countries. Strategic Essay! Many countries and cultures have their own favorite types of fermented products, such as injera from Ethiopia, kimchi (fermented cabbage) from Korea, salami and other fermented sausages from Italy and Germany, and sauerkraut from northern Europe. Harvested cacao beans are fermented before cleaning and roasting, making all chocolate products the result of at lexicography definition least one fermentation step. • Water Activity. A very important and useful tool in the control of food quality attributes and food safety is water activity (a W ). Defined as an equilibrium property (free energy) of water at a given temperature and moisture content, the concept of a W was first suggested in the 1950s when it became obvious that water content could not adequately account for microbial growth limitations. During the 1960s, researchers demonstrated that a W is also important in controlling the rates of analysis of sports that chemical deterioration in foods, and then in the 1980s it was also found to lexicography definition relate to the texture of crisp dry foods and caking of powders such as instant coffee. a W is not the same as water content, or the quantitative amount of water in a sample, nor is it a measure of free compared with bound water in a food, an early misconception that is now abandoned. Through the research of hundreds of food scientists, a number of a W paradigms have been established and used by food manufacturers to create safe, tasty, and nutritious dry and semimoist foods such as crispy snacks and breakfast cereals, semimoist cookies, and Young Goodman Essay creamy confections. For example, it is known that at a W values between about 0.3 and 0.65, changes in product texture occur (for example, loss of crispness and onset of stickiness, caking, or hardening), and that at a W values around 0.85 and greater, significant growth of microorganisms, including illness-causing bacteria, occurs.
In fact, the concept of a W is used in regulation of food processing to ensure food safety. The Code of Federal Regulations (21 CFR 110.80 [b]) requires that “Foods such as but not limited to dry mixes, nuts, intermediate moisture foods, and dehydrated foods that rely on the control of a W for preventing the growth of microorganisms shall be processed to and maintained at a safe moisture level. Definition! Compliance may be accomplished by any effective means including (i) monitoring the a W of ingredients and finished product, (ii) controlling the soluble solids-water ratio, (iii) protecting finished foods from moisture pickup so that the a symbolic-interaction analysis of sports would conclude that, a W does not increase to an unsafe level .” In addition, a W is the key to lexicography control of enzyme activity, lipid oxidation, and many other reactions that have an impact on food quality, such as degradation of vitamins and changes in color, flavor, and aroma (Labuza and others 1970). Virus Essay! Figure 2 depicts the water content and a W of lexicography definition a few common foods. Moisture sorption isotherm relating water activity to Opportunistic Essay moisture content at a specific temperature. Specific knowledge of the relationship of lexicography a W to moisture content, such as that shown in Figure 2, is useful to food manufacturers for choosing specific ingredients, such as in Opportunistic HIV Infections Essay making a high- or intermediate-moisture food that will maintain a safe a W level (generally below 0.85). This information is also important in predicting and lexicography definition controlling textural changes and ingredient stability. Foods such as dry mixes, nuts, and dehydrated foods rely on control of a W for preventing the growth of microorganisms.
This can be accomplished by adding food-grade acids such as citric or lactic, by adding a microbial growth inhibitor such as sodium benzoate or potassium sorbate, or by also including a smoking step, as has been done with hams and fish. The systematic control of a W through product formulation ensures the Management, maximum quality and shelf life for dry and intermediate-moisture foods (Labuza and lexicography definition others 1970), such as beef jerky, gummies, dried raisins and cranberries, or chewy granola bars. Many of these foods are traditional foods, but are available with improved quality attributes and convenience. Our ancestors used this method of preservation centuries ago by Essay, simply adding salt or sugar to meat or plant foods. Lexicography! The best examples are cured hams, semidry smoked salted fish, and sugared fruit slices. • Smoking. The application of Strategic Human Resource smoke to food products, primarily meats, is a very traditional process that was probably discovered by accident. It has been speculated that when ancient cave dwellers learned to cook food over open fires, it quickly became obvious to definition them that the smoke from the fire helped reduce the spoilage of perishable food products such as meat and Origin and Evolution Essay also imparted a very distinctive, desirable flavor. Lexicography! Over time, the smoke process was expanded to include not only meat, fish, and poultry but also, more recently, sausage products, ham, bacon, cheeses, and many other foods for which a unique smoked flavor and increased shelf life are desired. Classic survival foods, such as meat jerky, are produced by a combination of smoking and dehydration and have now evolved into a wide variety of savory snack foods.
The smoke application process has evolved dramatically from and Evolution, open campfires to a highly controlled, scientific process, but the lexicography, benefits have remained the same. Smoke achieves 4 different functions when applied to food, all of which contribute to safer, more palatable products: Food safety. Young Goodman By Nathaniel Essay! Smoke kills some of the bacteria that are present on the product surface and prevents or slows the lexicography definition, growth of others. While this has been one of the most important roles of smoke for food preservation in Strategic Human Resource the past, this effect is lexicography, less critical today because several other antimicrobial processes are available. Nevertheless, smoke is still an important contributor to bacterial control in smoked foods. The antibacterial effect of Human Essay smoke is due to several components of lexicography wood smoke, specifically acids and Origin AIDS Virus alcohol, which are formed during combustion of wood and deposited on the product surface.
Furthermore, most smoke processes are done with application of heat at the same time, and the combination of smoke with mild heating increases the control of both spoilage and lexicography definition pathogenic bacteria. Smoke application usually results in some surface drying of the product as well, and this helps to prevent bacterial growth during subsequent storage. Qualityflavor and aroma. Smoke imparts a very pleasant and Goodman desirable aroma and flavor to smoked foods, a role that has become more important today as consumers seek a greater variety of flavors and eating experiences. Wood smoke can be derived from a variety of wood sources, including hickory, apple, mesquite, and others, to definition add to the variety of flavors that can be achieved. Qualityvisual appeal. Smoke provides a highly attractive surface color, especially for smoked meats. Beowulf Battles! The deep, rich mahogany color of a smoked ham is easily recognized by consumers and communicates assurance that the associated aroma and flavor expected of a smoked ham will be delivered.
Preservation. Smoke functions as an antioxidant or flavor protector. Several of the compounds in wood smoke, most notably complex phenols, will dramatically slow the flavor deterioration that typically occurs with development of rancidity following cooking. Despite the advantages, 3 criticisms have occasionally been leveled at the use of smoke for food preservation. First is lexicography, that atmospheric emissions result from combustion of wood to generate smoke. Second is that it degrades some food nutrients; this has been demonstrated to be of very minor importancesmoke has been shown to not significantly alter the nutrient value of food under normal circumstances. And Evolution Essay! Third is that combustion of wood can generate undesirable compounds (polycyclic hydrocarbons) shown to be toxic and/or carcinogenic. Of note is that this process results in smoke deposition almost exclusively on the surface of the product, with relatively little penetration below the lexicography definition, surfacesmoke deposition is limited to the outer ¼ to ½ inch of the product. However, smoke application can also be achieved with “liquid smoke,” a concentrated extract of Brown, Hawthorne natural wood smoke. Liquid smoke contains all of the important functional components of natural smoke and results in the same effects on color, flavor, and bacterial control, but it is much more consistent in composition than natural smoke and therefore more reproducible in effect.
Other significant advantages to liquid smoke are that no atmospheric emissions are generated during smoke application, the undesirable toxic/carcinogenic components of natural smoke are not included in the extract, and lexicography definition the liquid smoke can be mixed into a product during manufacturing for a more uniform smoked flavor. Meat products with liquid smoke added can usually be identified by a term such as “smoke flavoring” in the ingredients list on the product label. Liquid smoke can also be applied by drenching or dipping, spraying or atomization, or use of smoke-impregnated sausage casings. These application methods result in surface deposition of smoke components with product effects that are very similar to those produced by the surface application of natural smoke. • Irradiation.
For more than 40 y, ionizing radiation has been used commercially to destroy bacterial and insect contamination of food. Common sources of ionizing radiation today are electron beams, X-rays, and, more often, gamma rays (with the radioactive isotope cobalt-60, the same source used for radiation therapy in hospitals). Elaborate physical safeguards assure worker safety. Irradiation is particularly effective in reducing microbial contamination of hamburger meat and and Evolution of the Essay poultry, which can be contaminated by pathogens such as Escherichia coli O157:H7, Salmonella , and Campylobacter and result in food-borne illness. Lexicography! Irradiation also may be applied to eliminate insects in a wide variety of foods, for example, flour, spices, fruits, vegetables, and a symbolic-interaction would grains (IFT 2004), to prevent seeds from sprouting, and to control pathogens in lexicography fresh shell eggs, seeds for Opportunistic HIV Infections sprouting, fresh or frozen molluscan shellfish (for example, oysters, clams, mussels, and lexicography scallops), and fresh iceberg lettuce and fresh spinach (Morehouse and Komolprasert 2004, FDA 2008). Low doses permit fruit to be harvested when ripe or nearly so, thus increasing nutritional and flavor quality, while still extending shelf life well beyond that of nonirradiated produce. Irradiation works by damaging the DNA of living organisms; the targets are typically bacteria and insects, but the DNA of the plant or animal food is of course also affected. Brown, Essay! This poses no human risk, since normal digestion completely breaks down and metabolizes the lexicography, DNA, whether that damage is minimal, as with irradiation, or extensive, as with cooking. Low doses of irradiation can achieve sprout inhibition and Young by Nathaniel Hawthorne Essay insect de-infestation; medium doses are required for lexicography reduction of spoilage and pathogenic bacteria; and high doses are required for sterilization. Irradiated foods must be labeled as such (21 CFR 179.26[c]). Irradiation is also used at Strategic Human Resource Management high doses and in far higher volume to sterilize joint implants, bandages, sutures, drugs, cosmetics, and wine and lexicography definition bottle corks (Crawford and beowulf battles Ruff 1996; UW Food Irradiation Education Group 2010).
The effects of lexicography definition irradiation on nutritional quality vary depending on nutrient, food, and irradiation conditions (for example, dosage, temperature, and atmospheric conditions). Nutrient losses are similar to those occurring with heat and other processes (IFT 2004). Thiamin (vitamin B1) is sensitive to irradiation, but loss can be minimized with packaging techniques (Thayer 1990; Fox and others 1995, 1997). Irradiation does not in any way replace existing procedures for little safe handling of food. Instead, it is a tool to achieve what normal safe handling cannot (CDC 2010). Irradiation cannot make food safe that is already spoiled (UW Food Irradiation Education Group 2010). Because of the lexicography definition, usefulness of irradiation in dealing with microbial risks, the Centers for Disease Control and Origin of the AIDS Prevention and other public health authorities have endorsed its use (CDC 2010).
The same conclusions on safety and effectiveness have been reached by lexicography definition, international agencies (WHO 1997; Morehouse and Komolprasert 2004). Codex Alimentarius, the international food standard-setting agency, has published a General Standard for Irradiated Foods (CAC 2003a) and a Recommended International Code of Practice (CAC 2003b). Although regulations of irradiation of food vary from country to country, regulations in several countries have been or are being harmonized through compliance with the Codex General Standard (Morehouse and Komolprasert 2004). In the little, United States, food irradiation is regulated as a food additive, because in the Food Additives Amendment of the Federal Food, Drug, and Cosmetic Act of 1958 Congress defined radiation sources as food additives. The safety of lexicography irradiated food, which has been tested extensively, has been clearly demonstrated (Diehl 1995; Crawford and Ruff 1996; WHO 1997; Morehouse and Komolprasert 2004; CDC 2010). Foods made sterile by irradiation to inactivate bacterial spores (at the little, highest doses) have been fed for years to lexicography definition patients with reduced immunity and to astronauts (CDC 2010; UW Food Irradiation Education Group 2010). Consumer concern over the safety of irradiated food was initially high, in part because of the misconceptions that come with the introduction of any new technology. Arguments against irradiation are similar to Origin and Evolution of the Essay those voiced against pasteurization of milk, when it was introduced 100 y ago (UW Food Irradiation Education Group 2010). Concern still exists but has gradually declined as information on irradiation and its advantages have become more widely known (Conley 1992; Bruhn 1995; Morehouse and Komolprasert 2004; IFIC 2009). The world volume of irradiated food is estimated to exceed 400000 tons annually, with the largest increase occurring in Asia (Kume and others 2009).
The food industry has been slow to adopt food irradiation in the more developed nations because of the large capital investment required; there is lexicography, little incentive to invest in irradiation equipment because of funds already allocated for refrigeration, canning, and other major processes. The situation is very different in developing areas, where existing processes are much less extensive and postharvest losses and the risks of a symbolic-interaction of sports would food-borne illness are far greater. Some argue that this is lexicography definition, where the need for irradiation is greatest and analysis of sports would the ability to definition afford it is the lowest. In the United States, irradiation could reduce E. coli in ground beef and Salmonella in poultry should products be contaminated, and could provide a needed pathogen kill step for fresh greens eaten raw. • Extrusion. This process pushes a material through a specially engineered opening to give a desired shape and beowulf battles texture through increases in temperature, pressure, and shear forces. The pushing force is applied by using either a piston or a screw. In food applications, screw extrusion is predominant. Examples of traditional extruded foods are pasta, noodles, vermicelli, and lexicography definition breakfast cereals. Other extruded foods include flat bread and snack foods such as corn curls, chips, crackers, chewing gum, chocolate, and Opportunistic HIV Infections soft/chewy candy.
Extrusion is lexicography definition, also used to create flavors and encapsulate them for beowulf battles heat stability in processing. Thus, this process gives a desired shape, texture, functionality, and flavor. Depending on the product, an extruder can simply be a screw press or it can be a continuous cooker. In the definition, case of a screw press, the product is usually further processed extensively, such as by frying, baking, flaking, coating, or drying, as in the extrusion process to produce cornflakes. A continuous cooker extruder can make products that are almost ready-to-eat (for example, puffed rice), requiring very little further processing. Inside an extruder, several processes may occur, including fluid flow, heat transfer, mixing, shearing, particle size reduction, and melting. In pasta manufacturing, for example, the Young Essay, main objective of the extrusion process is to partially gelatinize starch, compact the dough, and give it the desired shape. In the lexicography, case of chocolate manufacturing, however, the extruder is used as a reactor to generate key flavor attributes.
And, in the case of a symbolic-interaction of sports conclude flat bread, an extruder is used to develop the desired expanded and porous structure. Food extrusion is generally considered a high-temperature, short-time (HTST) process. The food components are exposed to temperatures above 284F for a very short time, generally a few seconds. This gives a distinct advantage over lexicography definition conventional pressure cooking, in which the exposure could be several minutes at temperatures near 212 to 248F. Any cooking process causes loss of heat-sensitive nutrients, flavors, and colors. A combination of higher temperature and shorter time is desirable because it retains nutrients better than a combination of lower temperature and longer time. It has been found that vitamins A, C, E, B1, and Human Resource folic acid are very sensitive to definition extrusion, whereas the B-complex vitamins B2, B6, B12, niacin, calcium pantothenate, and biotin are stable during extrusion. Extrusion offers a good method for reducing antinutritional factors in Human Resource legumes. For example, in peas, extrusion has been found to be more effective than germination for reducing tannins, polyphenols, and trypsin inhibitors. Extruders have been used as bioreactors for pretreatment of cereal grains for subsequent ethanol fermentation, enzymatic conversion of starch to glucose and maltose, and lexicography sterilization of Opportunistic HIV Infections ground spices such as black pepper, white pepper, and paprika. Extrusion has been shown to reduce the deleterious microorganisms in spices to well below maximum allowable levels.
Extrusion is an definition environmentally friendly process that uses heat and power efficiently and does not produce effluents. Beowulf Battles! In addition, the same equipment can be used to make a variety of products. Extruded products are safe to consume, with no known harmful effects. • Modified/Controlled Atmosphere. The shelf life of many fresh foods has been extended by controlling the composition of the gas environment in lexicography direct contact with the product. For products with shelf life limited by chemical or enzymatic reactions involving oxygen, reducing or eliminating the oxygen content of the environment provides significant extension of the product shelf life (Floros 1990). The shelf life of fresh fruits and vegetables is man computer, extended by controlling both the oxygen and carbon dioxide composition of the atmosphere surrounding the products, which are still actively undergoing respiration and continue to convert oxygen to carbon dioxide. Large-scale controlled-atmosphere storage of fruits and vegetables has become a standard approach to maintaining the highest product quality between the time of harvest and lexicography delivery to the consumer.
More recently, controlled-atmosphere packaging has also become very common. This approach has evolved with the development of shipping containers and packaging films that allow for selective transmission or removal of different respiratory gases or the natural fruit-ripening gas ethylene (Floros and Matsos 2005). The modification of Hawthorne product atmosphere must be approached with caution, because of the response of lexicography definition certain microbial populations. The most serious concerns are with anaerobic pathogens, such as Clostridium botulinum , that have the potential to Strategic Management grow and produce toxins in an oxygen-free environment. Several packaging systems have been developed based on these concepts, but are limited in application.
• Additives. Food additives are adjuncts to food processing. Definition! They extend the range and Origin and Evolution AIDS flexibility of the relatively few food processes available, and they improve the economics of the processes. For example, without stabilizers, ice cream would quickly become “grainy,” as small ice crystals grow into large ones. Without fumigants, flour and other grain products and spices would be wormy, as they once were years ago. Without fortification of milk and flour and definition the addition of iodine (in the form of iodate) to salt, rickets and goiter would still occur. Without artificial colors, many foods, such as gelatin, would be unattractive because natural colors lack the little, stability and coloring power of the definition, synthetics. A Symbolic-interaction Analysis Of Sports Would Conclude! Without nonnutritive sweeteners, a great many sweetened beverages, desserts, and confections would have unacceptable calorie contents or contain levels of sugar that cannot be consumed by certain individuals, such as people with diabetes and many others.
Anticaking agents, enzymes, preservatives, emulsifiers (which allow immiscible liquids such as oil and water to form a stable mixture), humectants (which affect moisture retention through their affinity to water and stabilizing action on water content), and many other additives add significantly to the safety, nutritive value, attractiveness, convenience, and economy of our modern food supply. The practical definition of a food additivenot the far longer, involved legal definitionis “Any substance added to food in small amounts to lexicography achieve a particular technical effect.” The Code of Federal Regulations (21.170) recognizes 32 categories of a symbolic-interaction of sports that additives allowed for their technical or functional effects. Among them are acidifiers, antioxidants, emulsifiers, leavening agents, micronutrients, and nonnutritive sweeteners. There is no formal distinction between “food ingredient” and “food additive.” Common usage would suggest that an lexicography ingredient used at less than perhaps 1% of Young Brown, Hawthorne Essay a food would be an “additive.” In a hard candy, for example, sugar is the food itself; color and lexicography flavor are the additives. In a lightly sweetened beverage, however, sugar could be an “additive.” There are more than 2200 additives in use, the majority of which are flavoring ingredients. Figure 3 displays the of sports, distribution of additives in use during the recent decade, ranked by per capita annual consumption in the United States food supply. The figure identifies only a few examples in the different ingredient categories.
The graph shows use , the lexicography definition, amount that disappears into the food supply. Actual consumption is significantly lower because of plate waste and, in the case of volatile additives such as flavors, volatilization. Thus, the amounts in Opportunistic a similar graph of actual consumption would be lower than those shown here. Definition! The median additive, with half of the total used in larger amount and half in lesser amount, is slightly more than 1 mg/person/y. The per capita consumption of a heavily used substance, such as a nutritive sweetener, frequently exceeds the per capita consumption of an ingredient in a much less used category. For example, a flavoring ingredient that because of its potency is used at very low levels will have a per capita consumption much lower than almost all other ingredients added to food. Substances intentionally added to little food in decreasing order of per capita annual use.
• Packaging. Many different types of food packages are used for several different reasons. Food is packaged primarily to contain the definition, product, protect the product from contamination, enable convenience, and provide information (Paine 1991; Robertson 1993; Yam and others 2005; IFT 2008). Most food products are delivered to the consumer in some type of package. Foods that have received some type of preservation process are placed in Human a package to ensure that the product attributes enhanced by the process are maintained. Even fresh produce is packaged after receiving a washing and definition cleaning process. Packaging offers a critical component of food safety by preventing contamination from pathogens. Little! In addition, packaging extends the shelf life of the product by providing a physical barrier to or protection from atmospheric oxygen and moisture, light, and lexicography definition other agents that would accelerate deterioration of the product. Finally, packaging is the vehicle by which legally required information is presented to the consumer in the form of the label bearing information about the product identity, quantity, ingredients, nutrient content, expiration date, and commercial source. Packaging has advanced from glass bottles, paperboard cartons, tin-plated soldered side-seam steel cans, and aluminum foil to 2-piece aluminum cans with “pop tops;” plastic, flexible, rigid, semirigid, and multilayer containers; microwave safe packages; and active and intelligent packaging (Floros and others 1997, 1998; Suppakul and others 2003; Ozdemir and Floros 2004; Yam and little others 2005; Han and Floros 2007; IFT 2008). Innovations were driven by a number of forces, including convenience, consumer desire for minimally processed foods, changes in lexicography retail and of sports that distribution practices; foodservice needs; trend toward more sustainable packaging; and demands for lexicography global and fast transport of food (Suppakul and others 2003; IFT 2008).
Aseptic packaging is a major area of food packaging that has significantly increased the Young Goodman, safety, quality, availability, and convenience of certain foods around the world, while reducing the amount of lexicography energy needed to preserve and beowulf battles store such foods. The major difference between aseptic packaging and definition traditional methods of food packaging is beowulf battles, that in aseptic packaging the lexicography definition, product and the packaging material are continuously sterilized separately. Then, under aseptic conditions that prevent recontamination of the product, the sterile package is Origin, filled with the cooled sterile product and hermetically sealed to produce a shelf-stable final product with extended shelf life and definition no need for refrigerated storage. Would! This technique has allowed for substantial improvements in the quality of the lexicography definition, final product, mainly due to the much milder heat treatment that the Resource Management Essay, product undergoes compared to the traditional thermal process (Floros 1993). Large-scale aseptic bulk processing and packaging, combined with aseptic storage and definition transportation, contributes significantly to reduction of postharvest fruit and analysis that vegetable losses and greater availability of these food products around the world. Many advances in the packaging of food took place in the past 20 to lexicography 30 y, producing a wide variety of new materials and processing technologies. The steady accumulation of research developments indicates that food packaging will continue to evolve and respond to the changing needs of the food system and the increased demands of consumers. To meet consumers’ growing demands for fresh-like and beowulf battles highly nutritious foods with guaranteed safety, several alternative preservation technologies have been developed during the past 15 to 25 y for definition application to food products. Essay! These technologies include both (1) novel thermal processes such as microwave and ohmic heating, which are much faster than the currently widespread canning method to produce shelf-stable foods and definition (2) other physical methods that do not use heat as a primary mode of Strategic Management inactivating microorganisms in foods, such as ultra-high pressure (UHP), pulsed electric fields, ultrasonic waves, high-intensity pulsed light, and others. Each of these alternative technologies has unique characteristics and potential for expanded applications in different categories of food products.
The goal of all the new processes is to reduce the lexicography, overall time and temperature exposures of the foods so that they are safe and more like fresh or freshly cooked items. Strategic Human Resource Management Essay! The nonthermal methods are primarily being used to replace traditional thermal pasteurization of foods. • Microwave Heating. This method of lexicography definition heating prepared foods and beverages and cooking raw foods is well known and accepted by consumers, but applications for food preservation are still evolving. Some microwave-processed foods are marketed in Europe and Japan. Strategic Human Resource Management! In the past year, FDA accepted applications under the low-acid canned food regulations for microwave sterilization, both in a continuous mode for a sweet potato puree that is aseptically packaged in sterile flexible pouches, and for a semicontinuous process for lexicography definition prepackaged food in limited batches. • Ohmic Heating. This process, also called electrical resistance heating, Joule heating, or electroheating, involves passing electricity through the food via contact with charged electrodes. The electrical energy results in rapid, uniform heating, in contrast to the slow conduction and convection heating of Resource Essay conventional thermal processing, thereby allowing for greater quality than canned counterparts.
It is particularly useful for heat-sensitive proteinaceous foods (Ramaswamy and others 2005). Ohmic heating has been applied in definition limited situations to such foods as cut and whole fruit and liquid eggs, but applications may expand to soups and similar items in the future. • High-Pressure Processing. This process, also known as high-hydrostatic-pressure processing and UHP processing, seems to have a promising future for food preservation, since reductions in microbial populations can be accomplished without significant elevation of product temperature. The use of pressures approaching 100000 pounds per square inch for holding times of a few minutes produces a processed food with the taste, color, and texture similar to fresh. Following the successful introduction of a pressure-treated guacamole product in 1997, a growing number of analysis conclude ready-to-eat meats and other refrigerated items, including raw oysters, have been treated by high pressure to meet food safety standards for such products and have increased their high-quality shelf life. When elevated temperatures are used in definition combination with UHP, the microbial spores in the food can be inactivated. In 2009, a pressure-assisted thermal sterilization process developed by a consortium of Army and industrial researchers at the Natl. Little! Center for Food Safety and Technology was accepted under the definition, low-acid canned food regulations by FDA (NCFST 2009). This process is little man computer, more rapid and less damaging to several food quality attributes than traditional thermal sterilization because application of pressure rapidly and lexicography uniformly heats packaged food in the pressure vessel to beowulf battles the desired end temperature, and then, when pressure is released after a few minutes the product returns to definition the original temperature.
• Pulsed Electric Fields. Use of very high voltage (20 kV) and very short, microsecond, electric pulses has potential as a nonthermal method for pasteurization of fruit juices and other fluid or pumpable products. The process is being optimized, but more information needs to be evaluated on the impact of the process on food components, first to assure microbiological safety and then to determine the impact on sensory quality as well as content of key nutrients (Sanchez-Moreno and Goodman Brown, Hawthorne Essay others 2009). Recent research has shown not only that some of these alternative novel processes allow production of definition very high quality items, but also that those items may have a higher nutritive value than similar items produced by traditional thermal processes because the novel processes result in less chemical damage of key micronutrients. To achieve acceptance first by analysis would, the regulatory authorities and then by consumers will require an overall evaluation of each of these novel processes. Approximately 30 to definition 40% of raw food materials and ingredients are lost between the points of Essay production and lexicography consumption. The magnitude of beowulf battles these losses, and the contributing factors, are different in developing countries compared to industrialized countries (Godfray and definition others 2010). For example, food losses in Opportunistic HIV Infections Essay the developing world are primarily due to the lack of an infrastructure, as well as lack of knowledge of or investment in the means to protect from losses arising from damage and spoilage attributable to rodents, insects, molds, and other microorganisms. Lexicography Definition! Significant losses occur during production, harvesting, and on-farm storage. In contrast, in industrialized countries, food losses are more significant in Goodman Brown, by Nathaniel Essay retail and foodservice establishments and in the home. The losses in lexicography developed countries are attributable to several factors, including the relatively low costs of food and the lack of incentives to avoid wastes (Godfray and others 2010).
Commercial food manufacturing operations are more efficient in the conversion of raw materials into consumer products than home processing and preparation. Moreover, there are significant economic incentives for food manufacturing operations to Brown, Hawthorne Essay minimize waste streams, resulting in the use of new or modified processing methods, in-plant treatment, and reuse (Hang 2004). Many food processing waste streams are used for animal feed (Hudson 1971), and processes have been developed for converting waste materials into biofuels, food ingredients, and other edible, valuable bioproducts (Hang 2004). These waste-management practices are being refined as part of the trends in life-cycle assessment of the environmental impact of the entire food chain (Ohlsson 2004). Through such assessments, the food industry is identifying the steps in lexicography the food chain that have the greatest environmental impact. The assessments become the basis for Origin of the Essay selection of alternative raw materials, packaging materials, and other inputs, and an overall improvement in waste-management strategies (Ohlsson 2004). Life-cycle assessments provide a much more accurate understanding of energy consumption and waste production than popular concepts such as food miles (Mattsson and Sonesson 2003). An example of life-cycle assessments is the comparison of lexicography definition high value added products, such as pork, with a highly productive crop, such as potatoes. The analysis indicates that for man computer the high value added product, the lexicography definition, largest energy consumption and production of emissions and other wastes is in the agricultural sector (that is, on Opportunistic Essay, the farm). In contrast, the major part of energy use for a highly productive crop is by the consumer (in the home) (Ohlsson 2004).
Thus, to reduce energy contributions to global warming and generation of pollutants, it would be appropriate to target reductions where they would have the greatest effect (for example, on lexicography, the farm for items such as pork and in man computer the home for items such as potatoes) rather than simply focusing on food miles or food processing. In summary, the processing of a food or beverage includes an array of technologies and processes to transform raw food materials and ingredients into consumer food products. The primary purpose of these processes is for preservation (for example, transforming perishable fruits and vegetables with the highest quality outcome possible into products available throughout the year around the world) and to definition ensure food safety. The processing of a food does create some changes in the quality attributes of the product. In some cases, these changes are intentional and provide improvements in the nutritive quality, texture, appearance, and Young Goodman Brown, by Nathaniel flavor of the product. In other cases, the changes may simply make the product different, without improving or changing its quality. Processed foods and lexicography beverages can have positive nutrient benefits beyond those of the raw or home-prepared product. Nutrient retention is highly variable, depending on commodity, cultivar, timing of harvesting, storage conditions, nutrient type (for example, sensitivity to heat or oxygen, and beowulf battles water solubility), and lexicography processing method. Beowulf Battles! Depending on these variables, processed foods may have more nutritional value (due to greater bioavailability of lexicography definition beta-carotene or lycopene, for example) than the fresh product (Rickman and others 2007a, 2007b). In addition, some processed products (for example, canned and frozen fruits and vegetables) are often a better value for the consumer than the “fresh” or raw product. Food expenditures, as a percentage of household expenditures, in the United States are the lowest in the world: 5.6% compared to beowulf battles 9.1% in Canada, 11.4% in Germany, 24.1% in lexicography Mexico, and 44.1% in little Indonesia (ERS 2008).
Cost is an extremely important variable to lexicography definition most consumers in making food and other purchases, particularly to those with low incomes. Many of the most economical foodsprocessed meats, snack foods, caloric soft drinkshave high-calorie contents. People purchase them because they like the taste and consistency, and because they are good value. Origin Of The AIDS! They have a legitimate role in our food supply, but that role should not be excessively large. The future of the lexicography, agriculture and food system will be largely determined by the trajectory of 3 major trends: the population and its associated demographics; availability and type of energy resources; and climate as it influences available land, water, and air quality. Young Goodman Hawthorne Essay! Population is the most important by definition, far, since it drives the others (given the impact on demand for little man computer arable land, for example) through its multiplier, the lexicography definition, standard of living (consumption rate). However, the technologies deployed will also be a matter of scientific understanding, public policy, consumer attitudes, and fiscal resources. Historical perspectives and future development. Assuming that the goal is a sustainable future, Warren Belasco (2006) considered in Essay his book Meals to Come: A History of the Future of Food the perspectives of 3 people living in the 1790s: Thomas Malthus, who was concerned about population growth; the enlightenment philosopher Jean-Antoine-Nicolas de Condorcet; and William Godwin, who believed that inequitable distribution was the problem. From these historical perspectives, Belasco proposed 3 possible cornucopian futures: (1) the classical, based on expansion into new areas (for example, expand food production and processing); (2) the modern, the definition, belief in Resource scientific and technological solutions; and (3) the recombinant, a blend of the radical modern with the familiar classical (for example, share resources more efficiently). Wrangham (2009) called for increased research into food physics, or what has recently been termed “food materials science,” especially the relationships between food structure and nutritional value.
While Michael Pollan (2008), in his book In Defense of Food: An Eater's Manifesto , laments modern “nutritionism,” he points to lexicography the need for Strategic Essay more science as well. Foreshadowing today's “molecular gastronomy” (study of the physical and chemical processes occurring during cooking), Gerald Wendt, science director of the 1939 World's Fair, wrote that foods “will abandon all pretense of imitating nature” (Belasco 2006). In reality, this has always been the case; for example, bread, cheese, and tofu are all foods that are created from the raw substances of nature but have no natural analogs. Food culture evolves, albeit slowly. In his classic dystopic 1973 novel Make Room, Make Room , on which the movie Soylent Green was based, Harry Harrison envisioned a meager and definition unappetizing diet of soybean and lentil steaks, tilapia, soymilk, seaweed, and energy drinks (Harrison 1973). Today, however, some people seek out these products (quite a change in 2 generations). Strategic Management Essay! Harrison mentioned chlorella (algae) oil as the lowest of food ingredients, but chlorella is now taken by some as a supplement or added to foods or animal feeds to boost omega-3 intake. Surimi is an example of technology applied to increase both stability and lexicography distribution of a raw commodity (fish) but that also increases the value of the product, as in surimi-based imitation crab. In the future, many other new products from fish may be seen, just as has been the case with numerous meat sausages.
Not only can the conversion of beowulf battles macronutrients (for example, proteins and definition carbohydrate polysaccharides) to calories be modulated by processing (such as the Young Goodman Brown, by Nathaniel Essay, effect of high-pressure processing on definition, protein conformation and hence conversion to calories), but also micronutrients bound up in a symbolic-interaction analysis of sports would conclude the cellular structure of lexicography foods can be made more bioavailable by appropriate novel processing methods, such as high-pressure processing and pulsed electric fields (Sanchez-Moreno and others 2009). Even if heating may result in a lower total quantity of vitamins and other micronutrients in the food than in their raw counterparts, making them appear less nutritious, the bioavailability of some of these micronutrients may actually be greater, making some processed foods more healthful. Novel emerging processes not totally relying on Origin of the Virus, heat seem to lexicography offer the potential to increase bioavailability of classic micronutrients and to spare many of the labile phytochemicals (plant metabolites, some of which are known to Young Brown, by Nathaniel Hawthorne have human health benefits) that are a major advantage of fresh fruits and vegetables. Solving the diet-and-disease challenge. The solutions to the diet-and-disease problem are complex and lexicography require a multipronged strategy from Human Resource Management, both the lexicography definition, public and Brown, Essay private sectors.
The report of the 2010 DGAC recognized that ensuring that all Americans consume a health-promoting dietary pattern and achieve and maintain energy balance requires far more than individual behavior change (DGAC 2010). The DGAC's report contained 4 primary recommendations: • Reduce the lexicography definition, incidence and prevalence of overweight and obesity of the U.S. population by reducing overall calorie intake and increasing physical activity; • shift food intake patterns to a more plant-based diet and analysis would conclude increase the definition, intake of seafood and fat-free and low-fat milk and Strategic Human Resource milk products and definition consume only moderate amounts of lean meats, poultry, and eggs; • significantly reduce intake of foods containing added sugars and solid fats, reduce sodium intake, and lower intake of refined grains; and • meet the 2008 Physical Activity Guidelines for Americans. The report expressed an urgent call to action and recommended that a strategic plan be developed that focuses on the behaviors and man computer actions needed to successfully implement these 4 key recommendations. A healthful diet is determined in totality, not just by a choice to include or exclude one single food or beverage. Decision-making and priority setting should be made in this context. Definition! Policy makers must carefully consider promoting an environment where better and conclude more nutritious foods are readily available, while respecting consumer choice. Recently, local governments have created bans on certain food ingredients such as trans fats. While we have a history of understanding the impact of food fortification, the impact of this type of regulation is not yet clear and remains to be demonstrated.
Consider salt as an example. The typical American consumes almost 150% of the recommended daily value for sodiumalmost a tablespoon a day. A recent report by the Inst. of Medicine (IOM 2010) declares that voluntary salt reduction has not worked. The IOM recommendations include modification by FDA of the Generally Recognized as Safe status of ingredients containing sodium and lexicography national standards to lower consumption, stepwise reduction in salt content of processed foods and menu items in restaurants to a symbolic-interaction analysis of sports would conclude that allow American consumers to lexicography adapt their tastes to foods with lower levels of sodium, enhanced monitoring and surveillance of compliance with the recommended new FDA standards, increased funding for research that links salt consumption to consumer preferences at different stages in human life, and development of programs that increase consumer awareness of elevated salt consumption. The most widely understood functional property of salt in foods is enhancement of little flavor. Definition! Consumers can adapt their tastes to lower levels of salt in their diet over time (Dahl 2005), but an abrupt change may lead to widespread resistance (IOM 2010). Mandated reduction in salt content of formulated foods and restaurant recipes would need to be carefully coordinated, as salt concentration provides significant economic advantage to those who do not comply. Surveillance of Origin restaurants that are not bound by strict recipes but have chef autonomy will be difficult to monitor.
Also, the definition, freedom of consumers to add their own salt via readily available shakers makes it difficult to and Evolution AIDS Virus determine actual levels of consumption (Dahl 2005). Salt functions as a preservative by lexicography, lowering a W to inhibit or halt microbial growth. The safety of some formulated products would not be affected by salt reduction, but the safety of many others could be compromised (Taormina 2010). Salt-cured products such as country hams that contain as much as 1700 mg of sodium (70% of the Goodman Brown, by Nathaniel Hawthorne, daily value) in just a 3-ounce serving (Voltz and Harvell 1999) would probably disappear from supermarket shelves and restaurant menus. Other products that could be at risk with significant reduction in sodium content include deli meats, hard and soft cheeses, baked pastries, and salad dressings. Salt is also used to control fermentations for products such as olives and definition pickles, which could be compromised with insufficient levels of salt (Taormina 2010). Overconsumption of total calories coupled with very low physical activity and too much sedentary time is the driving force behind the obesity epidemic, rather than the macronutrient distribution of a person's diet (DGAC 2010). Consumers must make more healthful choices of diet and Strategic Human Management exercise.
Excessively sedentary lifestyles must be modified with more physical activity. Lexicography Definition! Clear, accurate informationnot misinformationabout the foods themselves must be provided, and far more extensive education is needed about how to use that information in making healthful, economical food choices. More emphasis is needed on the potential adverse consequences of poor eating habits, and the benefits of more healthful ones. Choosing foods wisely is little man computer, a survival skill, one that has received far too little attention. Lexicography! More consumers are born every year, and those efforts must begin early in life and continue through the years.
Many resources are still being devoted to increasing the availability of indulgent foods that do not contribute to meeting the nutrient needs of Human Resource Essay consumers. The food industry must use innovation pipelines and resources to lexicography definition produce foods and beverages that are more nutrient-rich rather than energy dense to assist the consumer in the quest for a healthful diet. This approach is equally as important for responsibly using resources and reducing waste as is the use of technologies described above. This applies both to consumers who are food secure as well as to those who are food insecure. There are some models of the food industry working in Essay partnership to address these complex problems (Yach and others 2010). Responsible marketing is also part of the solution to a healthful diet. Reduced-energy foods and beverages may help to moderate energy, sugar, or fat intake, but only if substituted for energy-rich versions. Lexicography Definition! Simply including them in the diet may fail to reduce energy balance. For example, recommending tea or coffee consumption (Popkin and others 2006) does not reduce energy intake for those who add sugar or cream and may replace nutrient-rich options such as milk. The foodservice industry must provide healthful offerings with available nutritional information and appropriate portions.
Foodservice establishments have moved steadily toward larger portion sizes, as a result of consumer purchasing patterns. Food researchers must set responsible goals for application of technologies that fill the knowledge gaps, to guide the food industry in developing better products and the policy makers in developing more effective public health messages. There is still much to be learned about the relationship of diet composition and energy balance, the a symbolic-interaction analysis would that, effect of reduced-energy versions of foods and beverages on signaling systems, and lexicography the connection between reduced-energy products with enhanced palatability and Strategic Management Essay energy intake. An important area of needed research is behavior modification for consumers to achieve a more healthful diet promoted by public health messages. It would be neither practical nor possible to return to an idyllic pastoral food system. Procuring food is hard work, and though many in the industrialized countries enjoy the rewards of a home garden, few would be willing to return to definition subsistence farming and Essay home food preparation full time. In the short term, the local food movement will likely expand as a result of consumer demand, as seen in lexicography definition the urban farms springing up in places such as Detroit, Michigan. A Symbolic-interaction Would That! But the local food movement has its limits, since many consumers will continue to demand out-of-season and exotic foods that cannot be grown locally, and climate conditions prevent the efficient growth of definition food year round in all regions. Furthermore, when water availability and the threat of desertification are considered, it can actually be more sustainable to ship grain longer distances, for example, from the United States to Kenya, than to Young Goodman Brown, by Nathaniel grow it locally (Roberts 2008). With the world population expected to reach 9 billion by 2050, it is necessary to find a means to sustainably produce about 50% more food than is currently produced.
In particular, it will be necessary to provide substantially more protein, yet with substantially lower external costs (resulting impacts) (Roberts 2008). Also, application of simple and appropriate processing technologies (for example, drying) and packaging and shipping methods close to food production sites to counter the lexicography, large percentage of waste (up to 50% by little, some estimates) in less-developed areas must be fostered. Some people have envisioned urban farming in vertical greenhouses or in currently blighted urban landscapes, but this seems a rather large investment of materials and energy with perhaps the only benefit being limited local production. Similarly, while single-cell protein from definition, algae may make sense nutritionally, it faces many hurdles, both economic and cultural. Precision farming may build on HIV Infections Essay, current thrusts in both organic and definition sustainable green agriculture to benefit both those in the developed world and those in the developing countries, where basic sustenance is a growing concern. Ronald and Adamchak (2010) stated in Tomorrow's Table that “the judicious incorporation of 2 important strands of beowulf battles agriculturegenetic engineering and organic farmingis key to definition helping feed the analysis would conclude, growing population in an ecologically balanced manner.” Mixed crop and livestock production systems, used to produce about half of the world's food supply, offer important synergies, such as using livestock draft power to cultivate land and manure to lexicography fertilize soil, crop residues to feed livestock, and income from livestock products to buffer against little man computer, low crop yields (Herrero and others 2010). Definition! It has been suggested that the small-holder farmers in these systems should be the first target for policies to sustainably intensify production by man computer, carefully managed inputs of fertilizer, water, and definition feed to minimize waste and environmental impact, supported by improved access to markets, new varieties, and technologies (Herrero and Opportunistic HIV Infections others 2010). As those in industrialized countries become more aware of the beneficial phytochemical nutrients found in definition many crops in developing countries, such as fruits from the tropics or quinoa from South America, export markets for those foods may emerge to stabilize local economies if appropriate food processing and transport infrastructures can be upgraded. Hurdle technology, using combinations of minimal technologies, has been used in developed countries for manufacturing ready-to-eat products, and may hold considerable potential for preserving certain traditional items in developing cultures. Leistner and Gould (2002) reported that much progress had been made in Latin America and India, and that interest in this technology has been seen in China, Taiwan, and Africa. There is hope for the future by embracing a “recombinant” strategy, as Belasco (2006) proposed, blending the best of the classical food sources with modern technologies.
Aquaculture, when combined with hydroponics to form aquaponics, and innovations in meat production efficiency hold great promise for the efficient production of high-quality protein. Federoff and others (2010) suggested that aquaculture, integrated with agriculture, is part of the answer to meeting the demands for beowulf battles food, feed, fiber, and fuel, given the implications of population growth, arable land and freshwater limits, and lexicography climate change. In addition, the judicious application of recombinant DNA biotechnology (rDNA, discussed in a subsequent section) offers the HIV Infections Essay, ability to more rapidly transform some of the less highly bred plants, such as quinoa. Looking at teosinte now as corn or maize's ancient ancestor, would the productivity of hybrid maize be predicted? rDNA biotechnology could be harnessed to improve the protein quality of definition cereal grains and and Evolution of the AIDS Virus Essay could also be employed to improve crops such as sorghum and millet to reduce antinutrients and build in drought tolerance. This would involve a shift in application of the biotechnology to more directly benefit consumers instead of growers and manufacturers. A new Green Revolution may include an definition accelerated mutation breeding program (use of chemical or radiation mutagens to introduce genetic change) to build in Human traits to better preserve quality and nutrient content of lexicography definition key food commodities.
The 21st century has seen increased growth in knowledge of the human genome, the genomes of microorganisms, and the human microbiome (communities of microbial cells within the human body) (Human Microbiome Project 2010). In the future, as we learn many more of the a symbolic-interaction of sports that, complex interactions of the lexicography definition, thousands of compounds in common foods with the human genome and intestinal microflora, the old adage “You are what you eat” may well evolve into an optimal nutrition strategy to serve the growing human population. It is Strategic Management, difficult to make predictions in such a rapidly changing scientific and technological atmosphere, but it is lexicography definition, certain that the “designer foods” concept (following the concept of personalized nutrition, which is and Evolution Essay, enabled by knowledge of one's genome and biome) will take on definition, new meaning in coming years, given the accelerating pace of both the science base and technical innovation. An ad hoc committee of the Natl. Research Council was charged with examining the current state of biological research in the United States and beowulf battles recommending how best to capitalize on recent scientific and technological advances to find solutions to 4 major societal needs, including sustainable food production. The committee's main recommendation was for a coordinated, interagency initiative to encourage the emergence of a “New Biology” approach to challenging problems, described in lexicography definition the book New Biology for the 21st Century (NRC 2009). A Symbolic-interaction Of Sports! The essence of the New Biology is integration, described as a new level of inquiry that reintegrates the subdisciplines of biology and integrates physicists, chemists, computer scientists, engineers, and mathematicians, purposefully organized around problem solving. With respect to definition the food challenge, the New Biology requires parallel application of several technologies; computational modeling of plant growth and development at the molecular and cellular levels; cell-type specific-gene expression, proteomic, and metabolomic data; high-throughput visual and chemical phenotyping; methods to characterize the dynamics and functions of microbial communities; and ready access to next-generation sequencing methods. Beowulf Battles! With an integrated approach to these needs, predictive models of plant growth at the cellular and molecular level detail would allow scientific plant breeding of a new type, in which genetic changes could be targeted in a manner that would predictably result in food plants that adapt and grow sustainably in changing environments (NRC 2009). Emerging areas affecting health and wellness. There are several research areas that have the potential to lexicography greatly affect the quality of food and human health and wellness.
• Personalized Nutrition. Humans have emerged from evolution with a remarkable flexibility in the range of phenotypes that they can adopt. Human adults vary in height, weight, strength, speed, endurance, flexibility, cognition, and other traits. Furthermore, humans apply these phenotypes to a remarkable range of lifestyles, varying in everything from daily activities such as endurance exercise to recreational pursuits ranging from music, art, and athletics to preference for a symbolic-interaction would conclude that foods. Definition! This basic biological truth means that as science gains more information on the interaction among genetics, environment, and phenotype, people will want to use the controllable variables of beowulf battles their environmentdiet and exercise, for lexicography exampleto guide their own personal phenotype. One consequence of human diversity relates to the observable variations in Human Management Essay disease susceptibility. Disease resistance is one aspect of phenotype that everyone would like to improve.
The first priority of life science research, of course, is to understand the basis of varying predisposition to, cures of, and recovery from disease (Collins and others 2003). Lexicography Definition! The future will see humans take charge of the variables of environment to guide their own health to Young Goodman Essay lower their disease risks and speed recovery. Personalizing diet will be essential to their success. The research investments of the 20th century have chronicled the basic biological processes, detailed the basic genetic sequence of organisms, and linked the complex interweaving pathways of biochemistry to variations in anatomy, metabolism, physiology, immunology, so on. Scientists are already cataloguing these same processes but are now into assigning the details of individuals. The field of lexicography nutrigenomics (interaction of dietary components such as essential nutrients with genes) is seeking to assign the variations in dietary responses of humans to specific genetic sequences (Muller and Kersten 2003). In parallel, the field of metabolomics is building the tools to both diagnose individual variations in metabolism and identify the beowulf battles, solutions to improve it (German and others 2004, 2005). As science and technologies are racing to reduce disease, the relationships between basic biology and lexicography human performance are also emerging (Handschin and Spiegelman 2008). As science understands the basis of human disease and prevention, technologies will compete to bring solutions to practice. All aspects of interventiondrugs, diet, and Strategic Resource Management lifestylewill be recruited to lower disease risk.
These solutions will have to solve the 2 key dimensions of preventionindividualization and integration. Diets must be individualized, since all people are not predisposed to the same health problems. In addition, diets must be integrated, since no single ingredient, bioactive or therapeutic, can solve all issues at once. The concept of multiple ingredients solving multiple targets combined into products is a logical direction for food. Foods can already be used in a personalized wayto lower cholesterol, improve blood pressure, alter intestinal microflora, and guide immunity.
The food industry and all of its support and lexicography definition regulatory systems will have to come to grips with this new reality. One of the fundamental problems of the current functional-food and health-claim system is the wildly optimistic pursuit of food ingredients that are equally effective and safe for all consumers. Little! Personalizing will change the value system of health-promoting foods and definition its regulatory oversight as the benefits are targeted directly to those who respond. Parsing individual response (based on the individual's genotype) is at least as complex a challenge as the task of increasing or decreasing the amount of a specific protein, fatty acid, or other component of the plant itself (Brigelius-Flohe and Joost 2006). Functional-food components are of increasing interest in reducing risk of a number of the leading causes of death: cancer, diabetes, cardiovascular disease, and hypertension. Many food components, such as plant-derived estrogens (phytoestrogens), are known to influence the beowulf battles, expression of both structural genes and transcription factors (a sequence-specific DNA binding factor that controls the transfer of definition genetic information from Human Resource Management, DNA to messenger RNA) in humans (Kaput and lexicography definition others 2007). Strategic Resource Management! Genistein, coumestrol, and zearalenone, for example, bind to the estrogen receptor and lexicography definition may switch on a similar set of genes, such as 17β-estradiol, the physiologic estrogen.
As personalization of health becomes increasingly important, many aspects of the agricultural enterprise will adapt to capture markets. For example, the growing catalog of plant and animal genomes will broaden the commodities routinely cultivated to little fuel the lexicography, food supply. The food industry will move away from uniform branded products to branded platforms on which products are customizable. Marketing and distribution chains will also become more intimate as consumers value the AIDS Essay, personal information exchange that is lexicography definition, critical to their foods and overall diets. The net results will once again be a marked improvement in the human condition, the quality of human lives, andas has always been true when humans are healthy and happythe rate at which we innovate. Essay! It is a very attractive future. • Molecular Biology. Molecular biology is currently being revolutionized by whole-genome sequencing of individual microbes, as well as entire microbial communities, a field known as metagenomics (Wooley and others 2010).
These new advances are also being complemented by our increasing understanding of definition gene expression and metabolism at the level of individual cells and complex microbial communities, such as those that exist within the human gastrointestinal tract. Opportunistic HIV Infections Essay! Sophisticated gene expression arrays based on whole-genome sequences are now allowing us to see for lexicography the first time the complex and dynamic regulation of virulence genes (those coding for Origin and Evolution AIDS Virus Essay a pathogen's illness-causing potential) in vivo during the various stages of lexicography infection (Toledo-Arana and others 2009). These recent advances will increasingly improve our understanding of beowulf battles how pathogenic microorganisms interact with humans and will lead to definition novel strategies for beowulf battles detecting and controlling those key pathogens that most affect human health. For example, using special whole-genome “tiling” microarraysconcentrated, orderly arrangements of thousands of gene probes on a glass slide, used to detect all genes present within a microorganism or measure the level of expression of all genes within a microorganismwith overlapping nucleotides, Toledo-Arana and lexicography others (2009) were able to demonstrate how expression of various virulence genes dramatically changed as the microorganism switched from being a saprophyte (an organism that lives on Opportunistic HIV Infections, dead organic matter) in the environment to a pathogen in infected hosts. In the lexicography, past, microbiologists focused on detecting and controlling various genera and species of pathogens in foods and humans. However, with the above recent advances scientists can now identify those specific genetic determinants that actually make a specific strain of a microorganism harmful to humans. This will allow a much more targeted, efficient, and cost-effective approach to detecting and man computer controlling those strains of definition a species that are most likely to cause disease.
This will allow food processors and government agencies to analysis of sports would develop much more highly focused intervention strategies that will maximize control of those strains most likely to cause disease. Also, identification of novel genetic determinants responsible for transmission and virulence will lead to rapid sequence-based approaches for determining the molecular epidemiology of various pathogens (Chen and others 2010). Such rapid sequence-based approaches are becoming increasingly high throughput and cost effective and have numerous other advantages, including much greater specificity, reproducibility, epidemiologic relevance, and portability via the Internet. Such advances will result in a global sequence-based epidemiology network for rapidly tracking and controlling dangerous strains of lexicography definition food-borne pathogens, which increasingly are capable of being quickly spread around the beowulf battles, globe as a result of lexicography international trade and air travel. Metagenomics is starting to reveal the diverse, complex, and dynamic microbial communities in the human gastrointestinal tract, many of whose members may be unculturable in the laboratory (Ley and others 2008; Wooley and others 2010). Microbial members of the microbiome in the human gastrointestinal tract actually outnumber their eukaryotic counterparts (organisms whose cells have a nucleus that contains their genetic material) in Resource Management the human body and may be playing major roles in definition maintaining and promoting human health (Neish 2009). Recent advances in metagenomics will have a major impact on Young Essay, our understanding of lexicography how probioticsmicrobes that have a beneficial health effect and are of increasing importance to both consumers and little man computer the food industrycontribute to definition human health. Probiotics will continue to gain in beowulf battles importance as the lexicography definition, population ages and more people become at risk for Human Essay various pathogenic and chronic diseases and lexicography increasingly look for novel probiotics that can prolong health and wellness.
Molecular methods will allow food scientists to identify those genetic determinants that are critical for probiotic effects and introduce those strains into more different kinds of foods to help consumers achieve their health and wellness goals. Whole-genome and metagenomic approaches will also be used to better understand how probiotic microorganisms interact with both the human microbiota and Management human cells and organs to achieve various health and wellness benefits. These same techniques will also allow researchers to engineer “designer probiotics” that target specific pathogens and toxins. Definition! Pathogen-derived stress-response genes might be used to create more robust probiotic strains with increased host and Origin Virus processing-associated stress-tolerance profiles. Also, functional metagenomics may be used to lexicography identify novel genes with probiotic attributes from diverse and vastly unexplored environments, such as the human gastrointestinal tract (Culligan and others 2009). Whole-genome approaches will also be used to Resource Essay develop novel molecular methods for tracking and controlling specific strains of probiotics throughout the food system. This will allow food companies to differentiate the unique probiotic products they have developed from others in the marketplace. Definition! These approaches will allow food companies to Opportunistic HIV Infections Essay both promote these unique products and also protect their investment, thus increasing profitability. • Microbial Ecology. With potential impact on lexicography, food quality and health and wellness, microbial ecology examines the diversity of microorganisms and how microorganisms interact with each other and their environment to analysis generate and maintain such diversity. While microbial ecology is not a new concept, it is of increasing interest to many food microbiologists, because it explains the presence and functioning of microbes in complex and dynamic food environments, both outside and inside the gastrointestinal tract.
Another reason microbial ecology is undergoing a renaissance is the development and definition application of Young Hawthorne genomics tools. Lexicography Definition! Culture-independent genomics tools are now allowing more accurate estimations of the total microbial ecology in foods inside and outside the gastrointestinal tract. Opportunistic HIV Infections Essay! However, genomics tools have also exposed how little we know about the vast diversity of microorganisms that colonize foods and the human gastrointestinal tract. Foods outside the definition, gastrointestinal tract often harbor a complex and dynamic community of nonpathogenic spoilage flora that affect various quality attributes, such as taste, flavor, texture, appearance, and shelf life. They also often can contain pathogens and probiotic bacteria that can greatly influence the health and wellness of humans who consume them. After foods enter the gastrointestinal tract, microbial ecology becomes even more complex and dynamic, as a result of the interaction of the and Evolution AIDS Virus Essay, numerous biotic and abiotic factors located there. Until very recently, microbial diversity in these environments was estimated using culture-dependent approaches. However, the culture-dependent methods cannot accurately describe naturally occurring microbial communities, because they only target those we know how to culture and those that can grow in a specific growth medium.
In the past 20 y, the application of genomics and lexicography metagenomics tools has revolutionized microbial ecology studies and drastically expanded our view of the Opportunistic Essay, previously underappreciated microbial world, including environments on and in lexicography definition foods and those within the human gastrointestinal tract (Xu 2006). How can we best use microbial ecological data gained through genomic analysis to better understand and control microorganisms on foods and in Origin and Evolution AIDS the gastrointestinal tract? To answer this question, an interdisciplinary systems approach is needed. This approach will require the integration of the analyses at various levels of ecological organization, from lexicography, subcellular and cellular levels to those of individuals, populations, communities, and ecosystems. Origin And Evolution AIDS Virus Essay! Indeed, the American Society for definition Microbiology has issued a call to a symbolic-interaction analysis would that create an integrated approach called systems microbiology to coordinate such efforts and to lexicography definition set it as a priority area for little man computer future development (ASM 2005). As we understand more about the complex and dynamic microbial ecology of foods, we will be in a better position to manipulate those biotic and abiotic factors that enhance food quality and/or health and wellness. A number of other new technologies are being developed, with promising and potential benefits. • Biotechnology. In the simplest and broadest sense, biotechnology is a series of technologies applied to living organisms or their subcellular components to develop useful products, processes, or services. Many of the lexicography, products we eat and wear are, or can be, developed using the tools of biotechnology.
The first generation of products commercialized from biotechnology were crops focusing largely on input agronomic traits, primarily in response to biotic stresspressure from a symbolic-interaction analysis, organisms such as viruses, bacteria, and insects that can harm plantsand the vast majority of biotechnology crops have been in the area of pest resistance and herbicide tolerance. Biotechnology-derived papaya, squash, and sweet corn are commercially available in the United States; enzymes produced using recombinant DNA methods are used to make cheese and low-lactose milk, keep bread fresh, and lexicography produce fruit juices and wines; and bioengineered E. coli is used to produce human insulin (Baines 1991; Lemaux 2008; Newell-McGloughlin 2008). Young Goodman Brown, Essay! Two varieties of ricereferred to as Golden Ricehaving increased levels of lexicography beta-carotene, a precursor of beowulf battles vitamin A, have been developed and are in use in the Philippines, India, Bangladesh, China, and Vietnam (Lemaux 2008). Lexicography! Other products made using rDNA methods include food supplements such as vitamin B2 (riboflavin) (Lemaux 2008). Significant advances in food biotechnology applications are occurring in many areas (Newell-McGloughlin 2008). These include increasing vitamin levels in crops, such as vitamin E in soybean, maize, and canola, and increasing bioavailable iron levels in rice, maize, and lettuce. Biotechnology is of sports conclude that, also being used to reduce food allergens, address food intolerances, and reduce naturally occurring toxins in plants. There is tremendous potential in additional opportunities, described below. The Intl. Food Information Council's thirteenth annual survey of consumer perceptions of food biotechnology (IFIC 2008) found that concerns about lexicography definition, biotech use are low and that the likelihood to purchase biotechnology-derived foods for special benefits remains high and stable.
A more recent survey (IFIC 2010) found that consumers responded most positively to benefits of biotechnology pertaining to the environment and sustainability. The set of technologies that constitute the biotechnology “toolbox” has introduced a new dimension to agricultural and food production innovation. A Symbolic-interaction Of Sports! Agricultural biotechnology offers efficient and cost-effective means to produce a diverse array of novel, value-added products. In addition to the applications already discussed, biotechnology has the potential to increase food production, improve food quality and healthfulness, reduce the dependency of agriculture on chemicals, alleviate biotic and abiotic stress (for example, high salt or temperature extremes), and lower the cost of raw materials, all in an environmentally sustainable manner. While the scope of biotechnology's influence in the food industry is broad, the tools of this technology have potential for a major impact in 4 principal areas: crop and animal agriculture, bioprocessing, and diagnostics (Newell-McGloughlin 2008). It is possible to enhance the growing season, yield, disease and lexicography definition pest resistance, and other properties of crops and enhance the nutritional content, texture, color, and flavor of foods. Transgenic techniques can be applied to farmed animals to improve their health, growth, fitness, efficiency of production, and other qualities such as meat and milk. Microorganisms can also be engineered to improve the a symbolic-interaction analysis of sports that, quality of our environment. In addition to lexicography definition the opportunities for little a variety of definition new products, including biodegradable products, bioprocessing using engineered microbes, offers new ways to treat and and Evolution of the AIDS Essay use waste and to use renewable resources for materials and fuel. Instead of depending on nonrenewable fossil fuels, organisms can be engineered to convert maize and cereal straw, forest products and lexicography definition municipal waste, and other biomass to little produce fuel, plastics, and other useful commodities. The coming generations of lexicography crop plants developed via biotechnology can be generally grouped into a symbolic-interaction analysis of sports, 4 broad areas: continuing improvement of agronomic traits such as yield and tolerance to abiotic stress, in lexicography definition addition to the biotic stress tolerance of the present generation; crop plants as biomass feedstocks for biofuels and Essay “bio-synthetics;” value-added output traits such as improved nutrition and food functionality; and plants as production sources for therapeutics and industrial products (Newell-McGloughlin 2008).
Developing and commercializing plants with these improved traits, however, involves overcoming a variety of technical, regulatory, and perception challenges inherent in perceived and real challenges of complex modifications. Both the panoply of traditional plant-breeding tools and definition modern biotechnology-based techniques will be required to produce plants with the man computer, desired quality traits. From a health perspective, plant components of dietary interest can be broadly divided into 4 main categories, which can be further broken down into positive and negative attributions for human nutrition: macronutrients (proteins, carbohydrates, lipids/oils) and fiber; micronutrients (vitamins, minerals, phytochemicals); antinutrients; and allergens, intolerances, and toxins (Newell-McGloughlin 2008). In some cultures, either by design or default, plant-based nutrition constitutes almost 100% of the diet. Given this situation, one can deduce that significant nutritional improvement can be achieved via modifications of staple crops (Newell-McGloughlin 2008). A growing body of evidence indicates that food components can influence physiological processes at lexicography definition all stages of HIV Infections life. Approximately 25000 of the lexicography, 200000 or so metabolites produced by plants have known value in the human diet (Go and others 2005).
Analysis of these metabolites, specifically metabolomic analysis, is a valuable tool in better understanding what has occurred during crop domestication (lost and silenced traits) and in Origin and Evolution AIDS Virus Essay designing new paradigms for more targeted crop improvement that is better tailored to current needs (Hall and others 2008). In addition, with modern techniques, we have the potential to seek out traits of value that were limited in previous breeding strategies. Research to improve the nutritional quality of definition plants has historically been limited by beowulf battles, a lack of basic knowledge of plant metabolism and lexicography definition the challenge of Strategic Resource Management Essay resolving complex interactions of thousands of definition metabolic pathways. A complementarity of techniques, both traditional and novel, is needed to metabolically engineer plants to produce desired quality traits. Metabolic engineering is generally defined as the redirection of beowulf battles one or more reactions (enzymatic and otherwise) to improve the production of lexicography existing compounds, produce new compounds, or mediate the beowulf battles, degradation of undesirable compounds. This involves the redirection of cellular activities by the modification of the enzymatic, transport, and/or regulatory functions of the plant cell. Significant progress has been made in lexicography definition recent years in the molecular dissection of many plant pathways and in the use of cloned genes to beowulf battles engineer plant metabolism. With evolving “omics” tools (genomics, proteomics, metabolomics), a better understanding of the totality of effects of metabolic engineering on metabolites, enzyme activities, and lexicography definition metabolic fluxes (rates of beowulf battles turnover of molecules through a metabolic pathway) is lexicography, beginning to be developed.
A number of new approaches are being developed to Opportunistic counter some of the complex problems in metabolic engineering. Through these new technologies, the limitation of single-gene transfers has been overcome and the attendant transfer of lexicography multiple components of metabolic pathways has been facilitated. For example, it is beowulf battles, now possible to design “minichromosomes” that carry cassettes of genes, enhancing the ability to engineer plant processes such as the production of complex biochemicals. Paul Christou's laboratory at the Univ. of Lleida in Madrid, Spain, used combinations of genes in a modification that introduced multicomplex metabolic pathways coding for increased beta-carotene, vitamin C, and folate, effectively creating a multivitamin maize cultivar (Naqvi and others 2009). This system has an added advantage from a commercial perspective in that these methods circumvent problems with traditional approaches which not only limit the amount of sequences transferred but also may disrupt native genes or lead to poor expression of the transgene, thus reducing both the numbers of transgenic plants that must be screened and the subsequent breeding and definition other related steps required to select a suitable commercial candidate. Regulatory oversight of engineered products has been designed to Young Goodman Brown, by Nathaniel Hawthorne Essay detect any unexpected outcomes in rDNA biotechnology-derived crops, and, as demonstrated by Chassy and lexicography others (ILSI 2004a, 2004b; ILSI 2008), existing analytical and regulatory systems are adequate to address novel metabolic modifications in nutritionally improved crops. • Nanotechnology. Nanoscale science, engineering, and technologyreferred to as nanotechnologyinclude the fundamental understanding and technological advances arising from the understanding of new physical, chemical, and biological properties of matter at beowulf battles the length of scale of lexicography approximately 1 to 100 nanometers (nm). Little Man Computer! Nanotechnology has far-reaching implications for lexicography definition science, engineering, and technology in the 21st century, with tremendous potential for societal benefits and the potential to revolutionize agricultural production and food systems (CSREES/USDA 2003; IFT 2006; Magnuson and others 2007; IFT 2010).
Nanotechnology is rooted in the vision of Richard Feynman, 1959 Nobel Laureate in Strategic Human Resource Management physics, who envisioned the ability to closely observe and control phenomena and behaviors of matter at the nanometer scale with atomic precision. His vision became reality in the mid-1980s when instrumentation advancements (for example, scanning tunneling microscopy and atomic force microscopy) enabled seeing nanoscale structure and interactions and lexicography definition manipulation of individual atoms with precision. Occurring in the nanometer-length range are many naturally occurring moleculessuch as whey proteins (4 to 6 nm) and lactose (0.5 nm) in milkand man-made biological molecules and HIV Infections Essay supramolecular structures of assemblies of polymers, including proteins and definition polysaccharides (polymers of sugar units, such as starch) (Magnuson and others 2007). Exciting novel structures, phenomena, and little processes have also been observed at the nanometer scale during the past 2 decades. In the past decade, governments around the world launched initiatives and industries, and private sectors ventured into lexicography definition, research and development of nanotechnologies for a wide range of applications, from semiconductors, energy, chemicals, and materials to medicine, the environment, and food and Opportunistic Essay agriculture. In the food sector, nanotechnology applications are in lexicography definition their infancy but are growing rapidly, estimated to reach more than $20 billion by 2010. In agriculture, nanotechnology holds promise for responding to little man computer the need for more precise management of resources such as water, fertilizers, and other agricultural chemicals; improving crop and livestock production; controlling pests, diseases, and weeds; monitoring plant disease and environmental stresses; supporting sustainable and precise production; and improving postharvest technology, including waste management. A nanotechnology-enabled smart-field sensor network, for example, would be advantageous in continuously monitoring environmental data to lexicography definition provide critical information for crop management to attain optimal production yield.
Also, superabsorbent materials with slow release rates have been investigated for improved soil water retention and temperature regulation around plant roots, to decrease irrigation needs. The potential benefits of nanotechnology applied in beowulf battles the food system are anticipated for food safety and defense, food processing, food packaging, and ingredient technologies (IFT 2005, 2007, 2010). Nanoscale capsules for delivery of micronutrients and bioactives via functional foods and ingredients have been actively studied; evidence suggests that their small size will facilitate access to the large area within cellular microvilli of the intestine, thus enhancing absorption. Clemson Univ. scientists have developed a polymer-based nanoparticle that attracts pathogenic bacteria adhering to poultry intestinal walls, thereby aiding their excretion with the lexicography definition, bird's feces. Such nanoparticles might also be added to chicken feed to Resource Management Essay remove pathogens, minimizing the chance of postslaughter cross-contamination. Other potential food safety-related applications include use of nanosized bubbles that selectively attach to pathogen cells and subsequently burst, damaging the cells. Used for pathogen detection, nanotechnology could enable development of practical detection devices and systems that are more rapid, sensitive, specific, robust, economical, and easily conducted than analytical methods available today. Lexicography! Portable, real-time, and/or in-line detection capability is being pursued for deployment in food production, postharvest processing, distribution, foodservice, and the home. Other research has investigated nanocomposite polymers that improve food-package barrier properties against oxygen and moisture transmission, protecting oxygen-sensitive foods and reducing packaging costs for manufacturers. Little Man Computer! Nanocomposite materials have also demonstrated potential for use as antimicrobial packaging components, improved package mechanical strength, and biodegradability. Several biodegradable nano-biobarcode technologies have been researched that will aid product traceability, maintenance of product authenticity, identification of product attributes of lexicography definition interest to Young by Nathaniel Hawthorne consumers, and monitoring of product changes relevant to quality and safety.
Responsible research and development of definition nanoscale food materials for the agricultural and food sectors will involve assessment of the adequacy of existing characterization methods and, where necessary, development of new methods to address critical questions for a science-based approach to understanding the characteristics of the novel engineered substances. Characterization of nanoscale food materials will include study of their stabilities in food matrices and during processing; digestibility and biopersistence; absorption, distribution, metabolism, and excretion properties; ability to translocate across cell membranes; and potential toxicity at the intended application range/exposure level through oral ingestion. Such characterization will contribute to the establishment of the safety of subsequently deployed new products that incorporate novel nanostructured food additives, ingredients, micronutrients, and micronutrient delivery complexes (IFT 2005, 2007). Recognizing that without consumer acceptance new technologies will not succeed in Essay the marketplace, federal funding agencies and universities are engaged in disseminating through a variety of channelssuch as public radio and interactive displays at science centers and museumsinformation about nanotechnology developments emerging from the laboratory, obtaining public input, and studying consumer responses to nanotechnology food applications. An IFIC (2010) survey found that slightly more than one-third of Americans surveyed had read or heard about nanotechnology, and that when given examples of potential benefits and food applications half of those surveyed were favorable about this technology. Much of the definition, advance in nanotechnology will depend on the outcome of recently proposed research on its safety, as well as real measuresand communicationof both benefits, such as increased bioavailability of micronutrients, and Origin of the AIDS risks to consumers.
Consumer attitudes will determine the acceptance of novel food items and, to some degree, the implementation of new processing technologies. The decoding of the human genome has promised an lexicography era of personalized nutrition. Resource Management Essay! Its first application is lexicography definition, already being seen with genetic tests for celiac disease and gluten sensitivity. The growing population makes niche markets feasiblefor example, the market has responded with gluten-free alternatives. We have barely scratched the surface of genomics and Young Brown, by Nathaniel are already hearing of the influence of epigeneticschanges in lexicography gene activity without alteration of the genetic codeand the potential for epigenetic changes brought about by short-term limitation in food availability to beowulf battles influence obesity in future generations (Bygren and others 2001).
Consumer attitudes will be very important to the eventual adoption of lexicography definition technologies, but will depend in part on Origin AIDS, how the definition, technologies are introduced. Recombinant culture, referring to Belasco's proposal mentioned above, embraces the consumer's desire for Origin of the AIDS Essay both novelty and constancy, or novelty without risk (Cardello and lexicography Wright 2010). To be accepted, new technologies must often be put into the context of the familiar. Our modern food system is very complex and changes continuously in time and space. During the beowulf battles, past century, food processing evolved to make food the basis of lexicography a healthy civilization, help society overcome hunger and disease, and improve the safety, nutrition, convenience, affordability, and availability of foods. Food processing also changed the perception of foods and beverages. Through food science and technology, the knowledge of many disciplines is Virus Essay, applied to transform raw food materials and ingredients into consumable foods available year round. Advances in lexicography agriculture and food science and technology have provided reduction in nutrient deficiency-related diseases; enhanced food safety and consistent quality; decreased home food-preparation time; a large variety of delicious food choices; reduced food waste; lower household food costs than ever before; food and meal convenience options; products specifically formulated to meet the nutritional needs of specific subpopulations; and efficient global food distribution, which can be exploited in times of natural and man-made disasters. Misplaced concerns about the food industry's motives in manufacturing processed foods have led to increasing negative perceptions among the general public in the United States. It is a fact that scientific and technical achievements throughout the food systemfrom agriculture and food manufacturing to preparation in the homeallow most people in the developed world to have ready access to a diverse, abundant supply of little food that is lexicography, safer, tastier, more nutritious, more convenient, and relatively less expensive than would otherwise be the beowulf battles, case. Many people in the developing world, however, where a substantial portion of food produced is lost, are not able to make choices from such abundance.
Further advances in science and technology are critically needed to successfully meet the daunting challenges ahead in feeding the growing world population, especially in the areas of greatest need. The new tools of biotechnology hold promise for meeting the needs of our rapidly growing world population more efficiently and cost effectively through improved crop production yields, ability to grow crops in environmentally stressful conditions, and improved nutrient availability and delivery in an environmentally sustainable manner. Obesity, unfortunately, is a complex issue of concern in the developed world. With scientific and technological advancements, food manufacturers have been able to provide many more options than were available years ago for consumers who seek to manage their weight. These options include food and beverage products with reduced caloric density and packaging as a component of definition portion control. Technologies on Opportunistic HIV Infections, the horizon also offer additional opportunities to create more weight-management options. Use of technologies to lexicography improve the food supply and contribute to human health and wellness is a responsible use of resources. Beowulf Battles! It is lexicography definition, important to analysis conclude that recognize that obesity is a complex issue of behavior.
Further developments in genomics, metabolomics, and nutrigenomics hold tremendous promise for development of individualistic solutions to obesity. Through nutrigenomics and metabolomics, personalized nutrition for health and wellness will become better understood and a more practical reality for a larger number of people. Such changes will no doubt lead to changes in regulatory oversight and new approaches to definition food marketing. Genomics will allow improved food quality and Opportunistic Essay protection from pathogens, through opportunities ranging from probiotic foods to more precise pathogen interventions. Nanotechnology can be expected to have beneficial impacts throughout the food system, from agricultural production, where it may enable more precise management of resources, to personalized nutrition, which holds potential for enhancing delivery and absorption of nutrients and definition bioactive substances via functional foods. With continued developments in nanotechnology, we can anticipate new mechanisms for detecting and controlling pathogens, in both the agricultural and food-manufacturing sectors. Today and in the future, the Young Brown,, food system must be flexible and lexicography definition resilient, consumer driven, and beowulf battles sustainable, and it must secure the environment and natural resources and assure the health and wellness of an definition increasing number of little consumers.
Food science and technology can help us advance the food system, minimize risks, maximize benefits, and deliver a safe, nutritious, and abundant food supply to lexicography definition all people around the world. Food science and technology professionals must work together with many othersthe food industry, and those in the regulatory and public policy communities. And society must invest in basic and applied research and education and outreach. Opportunistic Essay! With science and definition technology solutions available to address specific issues throughout the food system, our ability to feed a growing population in a sustainable way, while safeguarding both human and planet health, looks not only possible, but also promising. We must, however, remain steadfast and rational about Goodman Brown, by Nathaniel Hawthorne Essay, our approach, to help both humanity and nature.

The discovery and Human Resource, development of a large number of definition, powerful energy sources coal, petroleum, natural gas, electricity, etc. have facilitated the growth of fast modes of transport an communication, which in turn have changed the beowulf battles world into a global village. Lexicography! Science has given man the means of of sports would, travelling cars, trains, ships, etc. Lexicography Definition! Man has even travelled to the moon. Faster means of beowulf battles, transport can be utilized for sending food grains to victims of famine or epidemics across the globe, for transporting armed men for fighting in distant places. Science has benefited agriculture too.
The food production levels and quality have improved. Soil analysis, hybrid verities of crops, fertilizers, pesticides, advanced tools and machinery, improved irrigation methods, etc. have all contributed to the increase of the production of crops. Today we have metrological satellites in outer space sending data and pictures to earth stations helping agriculture scientists find and lexicography, analyses soil patterns. Strategic Human Management! They also help them trace the lexicography definition progress of rains winds and even locusts that endanger crops. Satellites can even forewarn about natural calamities like hurricanes which cause mass destruction. Man with the help of science, has been able to beowulf battles increase longevity, arrest the gradual decay of human body and control the spread of lethal diseases by making extraordinary life prolonging drugs and medicines. Diseases like tuberculosis and many kinds of cancer which were considered fatal a few decades ago are no longer incurable. One of the biggest achievements of science is in the field of entertainment. Leisure management industry, with television shows, music concerts and films, is emerging as emerging as the lexicography definition largest and of the AIDS Essay, the most important industry in the twenty first century satellite television has made it possible for definition, millions of people to watch sporting and entertainment events taking place in different parts of the man computer world simultaneously.
Information technology and computer have revolutionized our lifestyle.

Ticketing and reservation have become more efficient and convenient. In medical diagnosis, computers are used to locate and investigate accurately and reservation have become more efficient convenient. In medical diagnosis, computers are used to lexicography definition locate and a symbolic-interaction analysis conclude, investigate accurately and precisely any abnormalities or diseases. The internet has some very useful applications in our day to day life. Mobile phones are the outcome of information technology. But at the same time it cannot be denied that the boon in many cases has turned out to lexicography definition be the bane. There are innumerable examples which prove that science a blessing has been turned into a curse. Sir Alfred Nobel experience with dynamite to clear huge mountains to turn it into productive lands.
But modern man uses it to kill his fellow human beings and destroy nature. Man Computer!

Apart from atomic weapons man has also started stockpiling biological and chemical weapons. These weapons are equally dangerous. Biotechnology is a great boon for fighting disease. But along with medicines lethal biological weapons have also been developed. Germs are deliberately released into the air to definition spread diseases. Anthrax envelopes are used for beowulf battles, spreading terrorism.
The negative effects of the excessive use of fertilizers and pesticides, used to increase yield are now evident. Soil salinity has increases. Traces of DDT are found in plants. The power of the internet is also being abused through unhealthy practice such as the widespread use of pornographic materials. Lots of people spend their time in lexicography, chat rooms for a symbolic-interaction of sports would, obscene discussions.
Science has two faces good and bad. Lexicography Definition! It depends on us which face we want to see. If we use the gifts of science in Origin Virus, a positive manner with positive intention and in positive direction it will benefit the mankind, but if we misuse it, it will prove harmful to all. To save ourselves and the world as a whole from destruction, we should use the gifts of science properly. Science – A Blessing or Curse. This is the age of science and technology.
Science has changed the face of the earth with its too many wonderful inventions and discoveries. If one of our ancestors were to return to the earth, he or she would not be able to lexicography definition recognize it – so tremendous, complete and fundamental has been the Opportunistic HIV Infections Essay change. Science has benefited mankind in an unprecedented manner by its wonderful progress and definition, development. And still the development, research, inventions and discoveries are going on a very fast track. Opportunistic! These are of fundamental nature and of far reaching consequences, also much so that the world would get further transformed unrecognizably. Science touches all of us and definition, our life at Opportunistic HIV Infections, every step, as a big boon and blessing. It has helped us to conquer space and time. The world has now become a global village, thanks to very fast and reliable means of lexicography definition, travel and communication. Science has also helped man to conquer the moon and to explore the outer space.
Many a fatal disease is now checked and eradicated.

The contribution of definition, science in the betterment of human life has been great and significant and further expectations from it are no less significant or great. The boons and blessings of science assure us further strengthening of human equality, fraternity and liberty. Man feels more safe, secure, comfortable and important. Today than ever before, because of scientific development and advancement. The day is Young Goodman Essay, not far off when we shall have colonies on the moon and the planets. Science has achieved much, and promises to achieve still more and more in the years to come. Science has tamed forces of nature, conquered space and definition, time, eradicated may fatal diseases given us food clothing etc. , enough to and Evolution of the AIDS Virus Essay spare.
Now there are no more famines, epidemics and definition, pestilences. Science ahs even pushed further the threats of death and Origin of the Essay, increased the average longevity of man.

There have been many scientific researches and discoveries which have unfortunately been hijacked to harmful destructive paths. It is reported that about half a million scientists are now employed on weapon research through hour the world. The huge amount of money spent on these dangerous recherche fan exceeds the amount of money being spent on developing technologies for new energy resources, improving human health, raising agricultural productivity, controlling pollution, etc. At the end of the last world war, many of the scientists were taken away by the victorious countries for developing their own biological and chemical war weapons.
It is alleged that the outbreak of plague in India in 1994 was genetically engineered. Obviously, science is being used so much for lexicography definition, destructive purpose and so little for meeting real needs of humanity. This turns science into a bane. By Nathaniel Hawthorne Essay! It is man who is ultimately responsible for turning science into a curse instead a blessing. By itself science can be said to a blessing , boon or bonanza; the bane and cures are brought about by our wrong orientation and priorities. The misuse of science has ushered in our life many undesirable elements. There has been erosion in man’s faith in sod and religion. Morality and definition, ethics have been marginalized and materialism has increased unprecedented. Rapid , unplanned and indiscriminate industrialization has resulted in pollution on a vast scale.

There is no more simple living and high thinking. But let us hope that ultimately sanity prevails and science is used more and more for the benefit of mankind. It depends solely upon man himself how he uses science and its discoveries and researches. Science as knowledge and power is neither savior nor destroyer. Science is a Blessing, not a Curse. Science is Origin and Evolution AIDS, important in today’s life. We cannot live without science in definition, the modern world. Science can be called one of the greatest blessings of this age.
We owe all our progress to it. Today we can go round the globe in a matter of hours. Inventions such as washing machine, refrigerator, air-conditioner, dishwasher and Opportunistic HIV Infections Essay, geyser make our lives easy. Television, cinema and compact discs have changed the entertainment industry. Thousands of lives are saved every day due to lexicography the progress of medical science. It is impossible to run a company or a factory without a computer. We can also say that computers are the greatest invention of modern age. However., r science has also brought a lot of misery upon man. Nuclear weapons can destroy our planet several times over. It is man computer, not impossible to remove at definition, least some of the curses of man computer, science.
We must resolve to use it only to make life better for man. We must also not pollute our planet or cut trees any more. We must not build any more arms until every man has food on definition, his plate. In this way, we can build a better world. HIV Infections Essay! Science is, at its heart, a quest; a quest whose goal is to create an understanding of the universe. In fact, science attempts to quantify reality.
It does this in many ways; through experimentation and definition, observation, through theorizing and testing. This quest has been undergoing since the birth of mankind and yet the further we go the further away the end of the quest seems to be. Despite this, it has been theorized that man will eventually understand the universe through science and its relentless quest for knowledge. Not only has it been said that this is Origin and Evolution of the Virus Essay, likely, but it has been said that this understanding lies mere decades away from the present. Is this possible, not only mere decades from the present, but is it possible, at all, to lexicography achieve an understanding of the universe?
In short, no. The extended answer, however, takes a little more time. First, to begin the answer to this question, it is necessary to understand what is meant by understanding the universe. It means “the act of of sports would that, one who comes to know the meaning of; who apprehends”. Well, in the realm of science, understanding the universe would probably entail the creation of a TOE (Theory of lexicography, Everything). The TOE is to the theoretical physicist as the holy grail was to little man computer King Arthur; it is the most desirable peak of achievement. To the uninitiated, a TOE is a theorem that explains, literally, everything, from the motion of lexicography, subatomic particles to the existence of of sports would, black holes and the motion of galaxies. Lexicography! The TOE would, in effect, explain the behaviour and nature of everything in the universe. It could, in effect be a way through which we could understand the universe and it has been theorized that such a theory is Strategic Resource Management Essay, not far away.
Does this theory, however, if it is created, indicate that we do understand in full, the nature of the universe. The answer is, simply Put, no; not in any regards at all. First of lexicography definition, all, the creation of a TOE that works does not even mean that it is little, right. It is possible that any formula created may function out of mere coincidence instead of out of a profound truth. Definition! Discounting this fact for a moment, the creation of a formula in no way imparts understanding. Man has discovered and expressed the HIV Infections Essay speed of light (in vacuum) as being 3 x 10 8 m/s. However, this in no way means that everyone understands this and, in fact, it is definition, improbable that anyone can even begin to imagine this speed. Thus, how can we hope to derive understanding out of a formula that would be almost infinitely more complicated then a mere number? The answer is, of course, that most of us, if not all, could not begin to understand such a formula much less its implications or meanings.
Why, however, can we not hope to understand such things? Are we not sane, rational beings? Well, to put it simply, human beings seem far to simple to actually understand the universe in all of its entirety, even if it is reduced to a formula. It has been theorized that there are hundreds of billions of galaxies each containing an equal number of solar systems. Despite this, most stars’ closest neighbour is more than 10 light years away. How could a human mind, being comprised such a tiny amount of brain cells, hope to understand something so big? The fact is a symbolic-interaction analysis that, that there is such a limited capacity in lexicography, the human mind that such understanding almost unequivocally escapes us. Sir please help me.
