Here, Darwinism seems to offer justification for if all humans share common origins it seems reasonable to suppose that cultural diversity could also be traced to more constrained beginnings.

To filter out what is unique from what is shared might enable us to understand how complex cultural behavior arose and what guides it in evolutionary or cognitive terms.

The second, by Joshua Greenberg, takes a more empirical approach to universality, identifying traits (particularly in word order) shared by many language, which are considered to represent biases that result from cognitive constraints.

Since the days of Aristotle, a search for universal principles has characterized the scientific enterprise. In some ways, this quest for commonalities defines science. Newton’s laws of motion and Darwinian evolution each bind a host of different phenomena into a single explicatory framework.(46)In physics, one approach takes this impulse for unification to its extreme, and seeks a theory of everything--a single generative equation for all we see. It is becoming less clear, however, that such a theory would be a simplification, given the dimensions and universes that it might entail, nonetheless, unification of sorts remains a major goal. This tendency in the natural sciences has long been evident in the social sciences too. (47)Here, Darwinism seems to offer justification for it all humans share common origins it seems reasonable to suppose that cultural diversity could also be traced to more constrained beginnings. Just as the bewildering variety of human courtship rituals might all be considered forms of sexual selection, perhaps the world’s languages, music, social and religious customs and even history are governed by universal features. (48)To filter out what is unique from what is shared might enable us to understand how complex cultural behavior arose and what guides it in evolutionary or cognitive terms.That, at least, is the hope. But a comparative study of linguistic traits published online today supplies a reality check. Russell Gray at the University of Auckland and his colleagues consider the evolution of grammars in the light of two previous attempts to find universality in language.The most famous of these efforts was initiated by Noam Chomsky, who suggested that humans are born with an innate language—acquisition capacity that dictates a universal grammar. A few generative rules are then sufficient to unfold the entire fundamental structure of a language, which is why children can learn it so quickly.(49)The second, by Joshua Greenberg, takes a more empirical approach to universality identifying traits (particularly in word order) shared by many language which are considered to represent biases that result from cognitive constraints.Gray and his colleagues have put them to the test by examining four family trees that between them represent more than 2,000 languages.(50)Chomsky’s grammar should show patterns of language change that are independent of the family tree or the pathway tracked through it. Whereas Greenbergian universality predicts strong co-dependencies between particular types of word-order relations. Neither of these patterns is borne out by the analysis, suggesting that the structures of the languages are lire age-specific and not governed by universals

yet when one looks at the photographs of the gardens created by the homeless, it strikes one that, for all their diversity of styles, these gardens speak of various other fundamental urges, beyond that of decoration and creative expression.

[A] Create a new image of yourself[B] Have confidence in yourself[C] Decide if the time is right[D] Understand the context[E] Work with professionals[F] Make it efficient[G] Know your goalsNo matter how formal or informal the work environment, the way you present yourself has an impact. This is especially true in the first impressions. According to research from Princeton University, people assess your competence, trustworthiness, and likeability in just a tenth of a second, solely based on the way you look.The difference between today’s workplace and the “dress for success” era is that the range of options is so much broader. Norms have evolved and fragmented. In some settings, red sneakers or dress T-shirts can convey status; in others not so much. Plus, whatever image we present is magnified by social-media services like LinkedIn. Chances are, your headshots are seen much more often now than a decade or two ago. Millennials, it seems, face the paradox of being the least formal generation yet the most conscious of style and personal branding. It can be confusing.So how do we navigate this? How do we know when to invest in an upgrade? And what’s the best way to pull oﬀ one that enhances our goals? Here are some tips:41._______As an executive coach, I’ve seen image upgrades be particularly helpful during transitions —when looking for a new job, stepping into a new or more public role, or changing work environments. If you’re in a period of change or just feeling stuck and in a rut, now may be a good time. If you’re not sure, ask for honest feedback from trusted friends, colleagues and professionals. Look for cues about how others perceive you. Maybe there’s no need for an upgrade and that’s OK._______Get clear on what impact you’re hoping to have. Are you looking to refresh your image or pivot it? For one person, the goal may be to be taken more seriously and enhance their professional image. For another, it may be to be perceived as more approachable, or more modern and stylish. For someone moving from finance to advertising, maybe they want to look more “SoHo.” (It’s OK to use characterizations like that.)_______Look at your work environment like an anthropologist. What are the norms of your environment? What conveys status? Who are your most important audiences? How do the people you respect and look up to present themselves? The better you understand the cultural context, the more control you can have over your impact._______Enlist the support of professionals and share with them your goals and context. Hire a personal stylist, or use the free styling service of a store like J. Crew. Try a hair stylist instead of a barber. Work with a professional photographer instead of your spouse or friend. It’s not as expensive as you might think._______The point of a style upgrade isn’t to become more vain or to spend more time fussing over what to wear. Instead, use it as an opportunity to reduce decision fatigue. Pick a standard work uniform or a few go-to options. Buy all your clothes at once with a stylist instead of shopping alone, one article of clothing at a time.

A sacred place of peace, however crude it may be, is a distinctly human need, as opposed to shelter, which is a distinctly animal need.

The gardens of the homeless, which are in effect homeless gardens, introduce form into an urban environment where it either didn’t exist or was not discernible as such.

most of us give in to a demoralization of spirit which we usually blame on some psychological conditions, until one day we find ourselves in a garden and feel the oppression vanish as if by magic.

It is speculated that gardens arise from a basic human need in the individuals who made them: the need for creative expression. There is no doubt that gardens evidence an irrepressible urge to create, express, fashion, and beautify and that self-expression is a basic human urge; (46)yet when one looks at the photographs of the gardens created by the homeless, it strikes one that, for all their diversity of styles, these gardens speak of various other fundamental urges, beyond that of decoration and creative expression.One of these urges has to do with creating a state of peace in the midst of turbulence, a “still point of the turning world,” to borrow a phrase from T. S. Eliot. (47) A sacred place of peace, however crude it may be, is a distinctly human need, as opposed to shelter, which is a distinctly animal need. This distinction is so much so that where the latter is lacking, as it is for these unlikely gardeners, the former becomes all the more urgent. Composure is a state of mind made possible by the structuring of one’s relation to one’s environment. (48) The gardens of the homeless, which are in effect homeless gardens, introduce form into an urban environment where it either didn’t exist or was not discernible as such. In so doing they give composure to a segment of the inarticulate environment in which they take their stand.Another urge or need that these gardens appear to respond to, or to arise from, is so intrinsic that we are barely ever conscious of its abiding claims on us. When we are deprived of green, of plants, of trees, (49) most of us give in to a demoralization of spirit which we usually blame on some psychological conditions, until one day we find ourselves in a garden and feel the oppression vanish as if by magic. In most of the homeless gardens of New York City the actual cultivation of plants is unfeasible, yet even so the compositions often seem to represent attempts to call forth the spirit of plant and animal life, if only symbolically, through a clumplike arrangement of materials, an introduction of colors, small pools of water, and a frequent presence of petals or leaves as well as of stuffed animals. On display here are various fantasy elements whose reference, at some basic level, seems to be the natural world. (50) It is this implicit or explicit reference to nature that fully justifies the use of word garden, though in a “liberated” sense, to describe these synthetic constructions. In them we can see biophilia—a yearning for contact with nonhuman life—assuming uncanny representational forms.

he believes that this very difficulty may have had the compensating advantage of forcing him to think long and intently about every sentence, and thus enabling him to detect errors in reasoning and in his own observations.

[A] The first and more important is the consumer’s growing preference for eating out; the consumption of food and drink in places other than homes has risen from about 32 percent of total consumption in 1995 to 35 percent in 2000 and is expected to approach 38 percent by 20This development is boosting wholesale demand from the food service segment by 4 to 5 percent a year across Europe, compared with growth in retail demand of 1 to 2 percent. Meanwhile, as the recession is looming large, people are getting anxious. They tend to keep a tighter hold on their purse and consider eating at home a realistic alternative. [B] Retail sales of food and drink in Europe’s largest markets are at a standstill, leaving European grocery retailers hungry for opportunities to grow. Most leading retailers have already tried e-commerce, with limited success, and expansion abroad. But almost all have ignored the big, profitable opportunity in their own backyard: the wholesale food and drink trade, which appears to be just the kind of market retailers need. [C] Will such variations bring about a change in the overall structure of the food and drink market? Definitely not. The functioning of the market is based on flexible trends dominated by potential buyers. In other words, it is up to the buyer, rather than the seller, to decide what to buy .At any rate, this change will ultimately be acclaimed by an ever-growing number of both domestic and international consumers, regardless of how long the current consumer pattern will take hold. [D] All in all, this clearly seems to be a market in which big retailers could profitably apply their scale, existing infrastructure and proven skills in the management of product ranges, logistics, and marketing intelligence. Retailers that master the intricacies of wholesaling in Europe may well expect to rake in substantial profits thereby. At least, that is how it looks as a whole. Closer inspection reveals important differences among the biggest national markets, especially in their customer segments and wholesale structures, as well as the competitive dynamics of individual food and drink categories. Big retailers must understand these differences before they can identify the segments of European wholesaling in which their particular abilities might unseat smaller but entrenched competitors. New skills and unfamiliar business models are needed too. [E] Despite variations in detail, wholesale markets in the countries that have been closely examined-France, Germany, Italy, and Spain-are made out of the same building blocks. Demand comes mainly from two sources: independent mom-and-pop grocery stores which, unlike large retail chains, are too small to buy straight from producers, and food service operators that cater to consumers when they don’t eat at home. Such food service operators range from snack machines to large institutional catering ventures, but most of these businesses are known in the trade as “horeca”: hotels, restaurants, and cafes. Overall, Europe’s wholesale market for food and drink is growing at the same sluggish pace as the retail market, but the figures, when added together, mask two opposing trends. [F] For example, wholesale food and drink sales come to $268 billion in France, Germany, Italy, Spain, and the United Kingdom in 2000-more than 40 percent of retail sales. Moreover, average overall margins are higher in wholesale than in retail; wholesale demand from the food service sector is growing quickly as more Europeans eat out more often; and changes in the competitive dynamics of this fragmented industry are at last making it feasible for wholesalers to consolidate. [G] However, none of these requirements should deter large retailers (and even some large good producers and existing wholesalers) from trying their hand, for those that master the intricacies of wholesaling in Europe stand to reap considerable gains. 41. →42. →43. →44. →[E]→45.

He asserted, also, that his power to follow a long and purely abstract train of thought was very limited, for which reason he felt certain that he never could have succeeded with mathematics.

On the other hand, he did not accept as well founded the charge made by some of his critics that, while he was a good observer, he had no power of reasoning.

He adds humbly that perhaps he was “superior to the common run of men in noticing things which easily escape attention, and in observing them carefully.”

In his autobiography, Darwin himself speaks of his intellectual powers with extraordinary modesty. He points out that he always experienced much difficulty in expressing himself clearly and concisely, but (46)he believes that this very difficulty may have had the compensating advantage of forcing him to think long and intently about every sentence, and thus enabling him to detect errors in reasoning and in his own observations. He disclaimed the possession of any great quickness of apprehension or wit, such as distinguished Huxley. (47)He asserted, also, that his power to follow a long and purely abstract train of thought was very limited, for which reason he felt certain that he never could have succeeded with mathematics. His memory, too, he described as extensive, but hazy. So poor in one sense was it that he never could remember for more than a few days a single date or a line of poetry. (48)On the other hand, he did not accept as well founded the charge made by some of his critics that, while he was a good observer, he had no power of reasoning. This, he thought, could not be true, because the “Origin of Species” is one long argument from the beginning to the end, and has convinced many able men. No one, he submits, could have written it without possessing some power of reasoning. He was willing to assert that “I have a fair share of invention, and of common sense or judgment, such as every fairly successful lawyer or doctor must have, but not, I believe, in any higher degree.” (49)He adds humbly that perhaps he was “superior to the common run of men in noticing things which easily escape attention, and in observing them carefully.”Writing in the last year of his life, he expressed the opinion that in two or three respects his mind had changed during the preceding twenty or thirty years. Up to the age of thirty or beyond it poetry of many kinds gave him great pleasure. Formerly, too, pictures had given him considerable, and music very great, delight. In 1881, however, he said: “Now for many years I cannot endure to read a line of poetry. I have also almost lost my taste for pictures or music.” (50)Darwin was convinced that the loss of these tastes was not only a loss of happiness, but might possibly be injurious to the intellect, and more probably to the moral character.

It may be said that the measure of the worth of any social institution is its effect in enlarging and improving experience; but this effect is not a part of its original motive.

[A] No disciplines have seized on professionalism with as much enthusiasm as the humanities. You can, Mr Menand points out, become a lawyer in three years and a medical doctor in four. But the regular time it takes to get a doctoral degree in the humanities is nine years. Not surprisingly, up to half of all doctoral students in English drop out before getting their degrees.[B] His concern is mainly with the humanities: literature, languages, philosophy and so on. These are disciplines that are going out of style: 22% of American college graduates now major in business compared with only 2% in history and 4% in English. However, many leading American universities want their undergraduates to have a grounding in the basic canon of ideas that every educated person should possess. But most find it difficult to agree on what a “general education” should look like. At Harvard, Mr Menand notes, “the great books are read because they have been read”--they form a sort of social glue.[C] Equally unsurprisingly, only about half end up with professorships for which they entered graduate school. There are simply too few posts. This is partly because universities continue to produce ever more PhDs. But fewer students want to study humanities subjects: English departments awarded more bachelor s degrees in 1970-71 than they did 20 years later. Fewer students require fewer teachers. So, at the end of a decade of thesis-writing, many humanities students leave the profession to do something for which they have not been trained.[D] One reason why it is hard to design and teach such courses is that they cut across the insistence by top American universities that liberal-arts education and professional education should be kept separate, taught in different schools. Many students experience both varieties. Although more than half of Harvard undergraduates end up in law, medicine or business, future doctors and lawyers must study a non-specialist liberal-arts degree before embarking on a professional qualification.[E] Besides professionalising the professions by this separation, top American universities have professionalised the professor. The growth in public money for academic research has speeded the process: federal research grants rose fourfold between 1960 and 1990, but faculty teaching hours fell by half as research took its toll. Professionalism has turned the acquisition of a doctoral degree into a prerequisite for a successful academic career: as late as 1969 a third of American professors did not possess one. But the key idea behind professionalisation, argues Mr Menand, is that “the knowledge and skills needed for a particular specialisation are transmissible but not transferable.” So disciplines acquire a monopoly not just over the production of knowledge, but also over the production of the producers of knowledge.[F] The key to reforming higher education, concludes Mr Menand, is to alter the way in which “the producers of knowledge are produced”. Otherwise, academics will continue to think dangerously alike, increasingly detached from the societies which they study, investigate and criticise. “Academic inquiry, at least in some fields, may need to become less exclusionary and more holistic.” Yet quite how that happens, Mr Menand does not say.[G] The subtle and intelligent little book The Marketplace of Ideas: Reform and Resistance in the American University should be read by every student thinking of applying to take a doctoral degree. They may then decide to go elsewhere. For something curious has been happening in American universities, and Louis Menand, a professor of English at Harvard University, captured it skillfully.

Only gradually was the by-product of the institution noted, and only more gradually still was this effect considered as a directive factor in the conduct of the institution.

While it is easy to ignore in our contact with them the effect of our acts upon their disposition, it is not so easy as in dealing with adults.

Since our chief business with them is to enable them to share in a common life we cannot help considering whether or no we are forming the powers which will secure this ability.

There is a marked difference between the education which every one gets from living with others, and the deliberate educating of the young. In the former case the education is incidental; it is natural and important, but it is not the express reason of the association. (46)It may be said that the measure of the worth of any social institution is its effect in enlarging and improving experience; but this effect is not a part of its original motive. Religious associations began, for example, in the desire to secure the favor of overruling powers and to ward off evil influences; family life in the desire to gratify appetites and secure family perpetuity; systematic labor, for the most part, because of enslavement to others, etc. (47)Only gradually was the by-product of the institution noted, and only more gradually still was this effect considered as a directive factor in the conduct of the institution. Even today, in our industrial life, apart from certain values of industriousness and thrift, the intellectual and emotional reaction of the forms of human association under which the world's work is carried on receives little attention as compared with physical output. But in dealing with the young, the fact of association itself as an immediate human fact, gains in importance. (48)While it is easy to ignore in our contact with them the effect of our acts upon their disposition, it is not so easy as in dealing with adults. The need of training is too evident; the pressure to accomplish a change in their attitude and habits is too urgent to leave these consequences wholly out of account. (49)Since our chief business with them is to enable them to share in a common life we cannot help considering whether or no we are forming the powers which will secure this ability. If humanity has made some headway in realizing that the ultimate value of every institution is its distinctively human effect we may well believe that this lesson has been learned largely through dealings with the young. (50)We are thus led to distinguish, within the broad educational process which we have been so far considering, a more formal kind of education -- that of direct tuition or schooling. In undeveloped social groups, we find very little formal teaching and training. These groups mainly rely for instilling needed dispositions into the young upon the same sort of association which keeps the adults loyal to their group.

Those societies came out of the war with levels of enrollment that had been roughly constant at 3-5% of the relevant age groups during the decades before the war.

Think of those fleeting moments when you look out of an aeroplane window and realise that you are flying, higher than a bird. Now think of your laptop, thinner than a brown-paper envelope, or your cellphone in the palm of your hand. Take a moment or two to wonder at those marvels. You are the lucky inheritor of a dream come true.The second half of the 20th century saw a collection of geniuses, warriors, entrepreneurs and visionaries labour to create a fabulous machine that could function as a typewriter and printing press, studio and theatre, paintbrush and gallery, piano and radio, the mail as well as the mail carrier. (41)____________.The networked computer is an amazing device, the first media machine that serves as the mode of production, means of distribution, site of reception, and place of praise and critique. The computer is the 21st century's culture machine.But for all the reasons there are to celebrate the computer, we must also tread with caution. (42)_____________I call it a secret war for two reasons. First, most people do not realize that there are strong commercial agendas at work to keep them in passive consumption mode. Second, the majority of people who use networked computers to upload are not even aware of the significance of what they are doing.All animals download, but only a few upload. Beavers build dams and birds make nests. Yet for the most part, the animal kingdom moves through the world downloading. Humans are unique in their capacity to not only make tools but then turn around and use them to create superfluous material goods - paintings, sculpture and architecture - and superfluous experiences - music, literature, religion and philosophy. (43)_________________For all the possibilities of our new culture machines, most people are still stuck in download mode. Even after the advent of widespread social media, a pyramid of production remains, with a small number of people uploading material, a slightly larger group commenting on or modifying that content, and a huge percentage remaining content to just consume. (44)______________Television is a one-way tap flowing into our homes. The hardest task that television asks of anyone is to turn the power off after he has turned it on.(45)__________________What counts as meaningful uploading? My definition revolves around the concept of "stickiness" - creations and experiences to which others adhere.[A]. Of course, it is precisely these superfluous things that define human culture and ultimately what it is to be human. Downloading and consuming culture requires great skills, but failing to move beyond downloading is to strip oneself of a defining constituent of humanity.[B]. Applications like tumblr.com, which allow users to combine pictures, words and other media in creative ways and then share them, have the potential to add stickiness by amusing, entertaining and enlightening others.[C]. Not only did they develop such a device but by the turn of the millennium they had also managed to embed it in a worldwide system accessed by billions of people every day.[D]. This is because the networked computer has sparked a secret war between downloading and uploading - between passive consumption and active creation - whose outcome will shape our collective future in ways we can only begin to imagine.[E]. The challenge the computer mounts to television thus bears little similarity to one format being replaced by another in the manner of record players being replaced by CD players.[F]. One reason for the persistence of this pyramid of production is that for the past half-century, much of the world's media culture has been defined by a single medium - television - and television is defined by downloading.[G]. The networked computer offers the first chance in 50 years to reverse the flow, to encourage thoughtful downloading and, even more importantly, meaningful uploading.

And the demand that rose in those societies for entry to higher education extended to groups and social classes that had not thought of attending a university before the war.

in many countries of Western Europe,the numbers of students in higher education doubled withinfive-year periods during the 1960s and doubled again in seven, eight, or 10 years by the middle of the 1970s.

and when the new staff are predominantly young men and women fresh from postgraduate study, they largely define the norms of academic life in that faculty.

World War II was the watershed event for higher education in modern Western societies. (46) Those societies came out of the war with levels of enrollment that had been roughly constant at3-5% of the relevant age groups during the decades before the war. But after the war, great social and political changes arising out of the successful war against Fascism created a growing demand in European and American economies for increasing numbers of graduates with more than asecondary school education(47) And the demand that rose in those societies for entry to higher education extended to groups and social classes that had not thought of attending a university before the war. These demands resulted in a very rapid expansion of the systems of higher education, beginning in the 1960s and developing very rapidly (though unevenly) during the 1970s and 1980s.The growth of higher education manifests itself in at least three quite different ways, and these in turn have given rise to different sets of problems. There was first the rate of growth: (48) in many countries of Western Europe,the numbers of students in higher education doubled withinfive-year periods during the 1960s and doubled again in seven, eight, or 10 years by the middle of the 1970s. Second, growth obviously affected the absolute size both of systems and individual institutions. And third, growth was reflected in changes in the proportion of therelevant age group enrolled in institutions of higher education. Each of these manifestations of growth carried its own peculiar problems in its wake. For example, a high growth rate placed great strains on the existing structures of governance, of administration, and above all of socialization. When a faculty or department grows from, say, five to 20 members within three or four years, (49) and when the new staff are predominantly young men and women fresh from postgraduate study, they largely define the norms of academic life in that faculty. And if the postgraduate student population also grows rapidly and there is loss of a close apprenticeship relationship between faculty members and students, the student culture becomes the chief socializing force for new postgraduate students, with consequences for the intellectual and academic life of the institution—this was seen in America as well as in France, Italy, West Germany, and Japan. (50) High growth rates increased the chances for academic innovation; they also weakened the forms and processes by which teachers and students are admitted into a community of scholars during periods of stability or slow growth. In the 1960s and 1970s, European universities saw marked changes in their governance arrangements, with empowerment of junior faculty and to some degree of students as well.

The social sciences are flourishing. As of 2005, there were almost half a million professional social scientists from all fields in the world, working both inside and outside academia. According to the World Social Science Report 2010, the number of social-science students worldwide has swollen by about 11% every year since 2000.Yet this enormous resource is not contributing enough to today’s global challenges, including climate change, security, sustainable development and health. (41)_______Humanity has the necessary agro-technological tools to eradicate hunger, from genetically engineered crops to artificial fertilizers. Here, too, the problems are social: the organization and distribution of food, wealth and prosperity.(42)_______This is a shame—the community should be grasping the opportunity to raise its influence in the real world. To paraphrase the great social scientist Joseph Schumpeter: there is no radical innovation without creative destruction.Today, the social sciences are largely focused on disciplinary problems and internal scholarly debates, rather than on topics with external impact. Analyses reveal that the number of papers including the keywords “environmental change” or “climate change” have increased rapidly since 20(43)_______When social scientists do tackle practical issues, their scope is often local: Belgium is interested mainly in the effects of poverty on Belgium, for example. And whether the community’s work contributes much to an overall accumulation of knowledge is doubtful.The problem is not necessarily the amount of available funding. (44)_______This is an adequate amount so long as it is aimed in the right direction. Social scientists who complain about a lack of funding should not expect more in today’s economic climate.The trick is to direct these funds better. The European Union Framework funding programs have long had a category specifically targeted at social scientists. This year, it was proposed that the system be changed: Horizon 2020, a new program to be enacted in 2014, would not have such a category. This has resulted in protests from social scientists. But the intention is not to neglect social science; rather, the complete opposite. (45)_______That should create more collaborative endeavors and help to develop projects aimed directly at solving global problems. [A] These issues all have root causes in human behavior: all require behavioral change and social innovations, as well as technological development. Stemming climate change, for example, is as much about changing consumption patterns and promoting tax acceptance as it is about developing clean energy.[B] Despite these factors, many social scientists seem reluctant to tackle such problems. And in Europe, some are up in arms over a proposal to drop a specific funding category for social- science research and to integrate it within cross-cutting topics of sustainable development.[C] During the late 1990s, national spending on social sciences and the humanities as a percentage of all research and development funds—including government, higher education, non-profit and corporate—varied from around 4% to 25%; in most European nations, it is about 15%.[D] It could be that we are evolving two communities of social scientists: one that is discipline- oriented and publishing in highly specialized journals, and one that is problem-oriented and publishing elsewhere, such as policy briefs.[E] However, the numbers are still small: in 2010, about 1,600 of the 100,000 social-sciences papers published globally included one of these keywords.[F] The idea is to force social scientists to integrate their work with other categories, including health and demographic change; food security; marine research and the bio-economy; clean, efficient energy; and inclusive, innovative and secure societies.[G] The solution is to change the mindset of the academic community, and what it considers to be its main goal. Global challenges and social innovation ought to receive much more attention from scientists, especially the young ones.

The time for sharpening pencils, arranging your desk, and doing almost anything else instead of writing has ended. The first draft will appear on the page only if you stop avoiding the inevitable and sit, stand up, or lie down to write. (41)_________Be flexible. Your outline should smoothly conduct you from one point to the next, but do not permit it to railroad you. If a relevant and important idea occurs to you now, work it into the draft. (42)_________ Grammar, punctuation, and spelling can wait until you revise. Concentrate on what you are saying. Good writing most often occurs when you are in hot pursuit of an idea rather than in a nervous search for errors.(43)_________ Your pages will be easier to keep track of that way, and, if you have to clip a paragraph to place it elsewhere, you will not lose any writing on the other side.If you are working on a word processor, you can take advantage of its capacity to make additions and deletions as well as move entire paragraphs by making just a few simple keyboard commands. Some software programs can also check spelling and certain grammatical elements in your writing. (44)_________ These printouts are also easier to read than the screen when you work on revisions.Once you have a first draft on paper, you can delete material that is unrelated to your thesis and add material necessary to illustrate your points and make your paper convincing. The student who wrote “The A & P as a State of Mind” wisely dropped a paragraph that questioned whether Sammy displays chauvinistic attitudes toward women. (45)_________ Remember that your initial draft is only that. You should go through the paper many times – and then again – working to substantiate and clarify your ideas. You may even end up with several entire versions of the paper. Rewrite. The sentences within each paragraph should be related to a single topic. Transitions should connect one paragraph to the next so that there are no abrupt or confusing shifts. Awkward or wordy phrasing or unclear sentences and paragraphs should be mercilessly poked and prodded into shape. [A] To make revising easier, leave wide margins and extra space between lines so that you can easily add words, sentences, and corrections. Write on only one side of the paper.[B] After you have clearly and adequately developed the body of your paper, pay particular attention to the introductory and concluding paragraphs. It’s probably best to write the introduction last, after you know precisely what you are introducing. Concluding paragraphs demand equal attention because they leave the reader with a final impression.[C] It’s worth remembering, however, that though a clean copy fresh off a printer may look terrific, it will read only as well as the thinking and writing that have gone into it. Many writers prudently store their data on disks and print their pages each time they finish a draft to avoid losing any material because of power failures or other problems.[D] It makes no difference how you write, just so you do. Now that you have developed a topic into a tentative thesis, you can assemble your notes and begin to flesh out whatever outline you have made.[E] Although this is an interesting issue, it has nothing to do with the thesis, which explains how the setting influences Sammy’s decision to quit his job. Instead of including that paragraph, she added one that described Lengel’s crabbed response to the girls so that she could lead up to the A & P “policy” he enforces.[F] In the final paragraph about the significance of the setting in “A & P,” the student brings together the reasons Sammy quit his job by referring to his refusal to accept Lengel’s store policies.[G] By using the first draft as a means of thinking about what you want to say, you will very likely discover more than your notes originally suggested. Plenty of good writers don’t use outlines at all but discover ordering principles as they write. Do not attempt to compose a perfectly correct draft the first time around.

Coinciding with the groundbreaking theory of biological evolution proposed by British naturalist Charles Darwin in the 1860s, British social philosopher Herbert Spencer put forward his own theory of biological and cultural evolution. Spencer argued that all worldly phenomena, including human societies, changed over time, advancing toward perfection. 41.____________.American social scientist Lewis Henry Morgan introduced another theory of cultural evolution in the late 1800s. Morgan, along with Tylor, was one of the founders of modern anthropology. In his work, he attempted to show how all aspects of culture changed together in the evolution of societies.42._____________.In the early 1900s in North America, German-born American anthropologist Franz Boas developed a new theory of culture known as historical particularism. Historical particularism, which emphasized the uniqueness of all cultures, gave new direction to anthropology. 43._____________ . Boas felt that the culture of any society must be understood as the result of a unique history and not as one of many cultures belonging to a broader evolutionary stage or type of culture. 44._______________.Historical particularism became a dominant approach to the study of culture in American anthropology, largely through the influence of many students of Boas. But a number of anthropologists in the early 1900s also rejected the particularist theory of culture in favor of diffusionism. Some attributed virtually every important cultural achievement to the inventions of a few, especially gifted peoples that, according to diffusionists, then spread to other cultures. 45.________________. Also in the early 1900s, French sociologist ?mile Durkheim developed a theory of culture that would greatly influence anthropology. Durkheim proposed that religious beliefs functioned to reinforce social solidarity. An interest in the relationship between the function of society and culture—known as functionalism—became a major theme in European, and especially British, anthropology.[A]Other anthropologists believed that cultural innovations, such as inventions, had a single origin and passed from society to society. This theory was known as diffusionism.[B]In order to study particular cultures as completely as possible, Boas became skilled in linguistics, the study of languages, and in physical anthropology, the study of human biology and anatomy.[C]He argued that human evolution was characterized by a struggle he called the “survival of the fittest,” in which weaker races and societies must eventually be replaced by stronger, more advanced races and societies.[D]They also focused on important rituals that appeared to preserve a people’s social structure, such as initiation ceremonies that formally signify children’s entrance into adulthood.[E]Thus, in his view, diverse aspects of culture, such as the structure of families, forms of marriage, categories of kinship, ownership of property, forms of government, technology, and systems of food production, all changed as societies evolved.[F]Supporters of the theory viewed as a collection of integrated parts that work together to keep a society functioning.[G]For example, British anthropologists Grafton Elliot Smith and W. J. Perry incorrectly suggested, on the basis of inadequate information, that farming, pottery making, and metallurgy all originated in ancient Egypt and diffused throughout the world. In fact, all of these cultural developments occurred separately at different times in many parts of the world.

In the movies and on television, artificial intelligence is typically depicted as something sinister that will upend our way of life. When it comes to AI in business, we often hear about it in relation to automation and the impending loss of jobs, but in what ways is AI changing companies and the larger economy that don’t involve doom-and-gloom mass unemployment predictions?A recent survey of manufacturing and service industries from Tata Consultancy Services found that companies currently use AI more often in computer-to-computer activities than in automating human activities. Here are a few ways AI is aiding companies without replacing employees:Better hiring practices Companies are using artificial intelligence to remove some of the unconscious bias from hiring decisions. “There are experiments that show that, naturally, the results of interviews aremuch more biased than what AI does,” says Pedro Domingos, author of The Master Algorithm: How the Quest for the Ultimate Learning Machine Will Remake Our World and a computer science professor at the University of Washington."(41)__________________________________________"One company that's doing this is called Blendoor. It uses analytics to help identify where there may be bias in the hiring process.More effective marketing Some AI software can analyze and optimize marketing email subject lines to increase open rates. One company in the UK, Phrasee, claims their software can outperform humans by up to 10 percent when it comes to email open rates. This can mean millions more in revenue. (42)______ These are “tools that help people use data, not a replacement for people,” says Patrick H.Winston, a professor of artificial intelligence and computer science at MIT.Saving customers moneyEnergy companies can use AI to help customers reduce their electricity bills, saving them money while helping the environment. Companies can also optimize their own energy use and cut down on the cost of electricity. Insurance companies, meanwhile, can base their premiums on AI models that more accurately access risk. Domingos says,“ (43) ________________________.”Improved accuracy “Machine learning often provides a more reliable form of statistics which makes data more valuable,” says Winston. It “helps people make smarter decisions.” (44) .Protecting and maintaining infrastructure A number of companies, particularly in energy and transportation, use AI image processing technology to inspect infrastructure and prevent equipment failure or leaks before they happen. “If they fail first and then you fix them, it’s very expensive,” says Domingos. “ (45)______________________________.”

(41) Teri ByrdI was a zoo and wildlife park employee for years. Both the wildlife park and zoo claimed to be operating for the benefit of the animals and for conservation purposes. This claim was false. Neither one of them actually participated in any contributions whose bottom line is much more important than the condition of the animals.Animals despise being captives in zoos. No matter how you “enhance” enclosures, they do not allow for freedom, a natural diet or adequate time for transparency with these institutions, and it's past time to eliminate zoos from our culture.(42) Karen R. SimeAs a zoology professor, I agree with Emma Marris that zoo displays can be sad and cruel. But she underestimates the educational value of zoos.The zoology program at my university attracts students for whom zoo visits were the crucial formative experience that led them to major in biological sciences. These are mostly students who had no opportunity as children to travel to wilderness areas, wildlife refuges or national parks. Although good TV shows can help stir children's interest in conservation, they cannot replace the excitement of a zoo visit as an intense, immersive and interactive experience.Surely there must be some middle ground that balances zoos' treatment of animals with their educational potential.(43) Greg NewberryEmma Marris's article is an insult and a disservice to the thousands of passionate who work tirelessly to improve the lives of animals and protect our planet. She uses outdated research and decades-old examples to undermine the noble mission of organization committed to connecting children to a world beyond their own.Zoos are at the forefront of conservation and constantly evolving to improve how they care for animals and protect each species in its natural habitat. Are there tragedies? Of course. But they are the exception not the norm that Ms. Marris implies. A distressed animal in a zoo will get as good or better treatment than most of us at our local hospital.(44) Dean GalleaAs a fellow environmentalist animal-protection advocate and longtime vegetarian. I could properly be in the same camp as Emma Marris on the issue of zoos. But I believe that well-run zoos and the heroic animals that suffer their captivity so serve a higher purpose. Were it not for opportunities to observe these beautiful wild creatures close to home many more people would be driven by their fascination to travel to wild areas to seek out disturb and even hunt them down.Zoos are in that sense similar to natural history and archeology museums serving to satisfy our need for contact with these living creatures while leaving the vast majority undisturbed in their natural environments.(45) John FraserEmma Marris selectively describes and misrepresents the findings of our research. Our studies focused on the impact of zoo experiences on how people think about themselves and nature and the data points extracted from our studies.Zoos are tools for thinking. Our research provides strong support for the value of zoos in connecting people with animals and with nature. Zoos provide a critical voice for conservation and environmental protection. They afford an opportunity for people from all backgrounds to encounter a range of animals from drone bees to springbok or salmon to better understand the natural world we live in.
