Many animals have some level of social intelligence, allowing them to coexist and cooperate with other members of their species. Wolves, for example—the probable ancestors of dogs—live in packs that hunt together and have a complex hierarchy. But dogs have evolved an extraordinarily rich social intelligence as they've adapted to life with us. All the things we love about our dogs—the joy they seem to take in our presence, the many ways they integrate themselves into our lives—spring from those social skills. Hare Brian, assistant professor of evolutionary anthropology at Duke University, and others are trying to figure out how the intimate coexistence of humans and dogs has shaped the animal's remarkable abilities. Hare suspects that the evolutionary pressures that turned suspicious wolves into outgoing dogs were similar to the ones that turned combative apes into cooperative humans. "Humans are unique. But how did that uniqueness evolve?" asks Hare. "That's where dogs are important." The first rule for scientists studying dogs is, don't trust your hunches . Just because a dog looks as if it can count or understand words doesn't mean it can. "We say to owners, look, you may have intuitions about your dog that are valuable," says Marc Hauser, a cognitive psychologist at Harvard University. "But they might be wrong." Alexandra Horowitz, a cognitive scientist at Barnard College, and other scientists are now running experiments to determine what a behavior, like a kiss, really means. In some cases, their research suggests that our pets are manipulating us rather than welling up with human-like feeling. "They could be the ultimate charlatans ," says Hauser. We've all seen guilty dogs slinking away with lowered tails, for example. Horowitz wondered if they behave this way because they truly recognize they' ve done something wrong, so she devised an experiment. First she observed how dogs behaved when they did something they weren't supposed to do and were scolded by their owners. Then she tricked the owners into believing the dogs had misbehaved when they hadn't. When the humans scolded the dogs, the dogs were just as likely to look guilty, even though they were innocent of any misbehavior. What's at play here, she concluded, is not some inner sense of right and wrong but a learned ability to act submissive when an owner gets angry. "It's a white-flag response," Horowitz says. While this kind of manipulation may be unsettling to us, it reveals how carefully dogs pay attention to humans and learn from what they observe. That same attentiveness also gives dogs—or at least certain dogs—a skill with words that seems eerily human.

[A]Monitor your alcohol use [B]Pay attention to table manners [C]Don' t be a gossip [D]Network with higher-ups [E]Keep the conversation light [F]Dress appropriately [G]Make new friends For young workers, holiday parties can be a wonderful opportunity to celebrate a successful year gone by, catch up with colleagues and hobnob with senior executives to try to get ahead. But a host of challenges confront young employees—from figuring out whom to bring to walking the fine line between being friendly and being flirty. Some do' s and don 'ts when it comes to these events: 【R1】______ If you' re new to the company, talk to co-workers who have attended previous office functions to get a sense of what you should wear. Dress conservatively, not "like you're going to a club in Vegas, "says Tom Gimbel, CEO of staffing firm LaSalle Network in Chicago. But, he adds, don't take it "to the point where(you're)wearing a suit where everybody else is wearing jeans." 【R2】______ Steer clear of talking about those layoffs or pay freezes that have hit morale, experts advise. "Try to keep the conversation upbeat," says Barbara Pachter, president of Pachter & Associates, a business-etiquette and communications firm in Cherry Hill, N.J. "If you're merging, that could be an exciting thing,(or if)you're adding new product lines, that could be an exciting thing" to talk about. 【R3】______ While it' s fun to indulge in rumors about colleagues, you don' t want to be known as the person who' s always spreading juicy gossip. "You want to be known for your work ethic, you want to be known for the work product that you put out, and at a holiday party, you don't want to be the one telling everybody who' s making out with whom and who' s fighting with whom," says Mr. Gimbel. Instead, he encourages people to stick to safe topics like sports, entertainment and what' s going on in the world. 【R4】______ Even if you're intimidated by the clique of VPs huddling in their own circle, don't pass up the opportunity to meet these people, who could be interviewing you when you' re up for your next promotion. Look for an opening to chime in on a topic that you know about. If they don't already know you, introduce yourself and say how long you've been with the company and what you do. Afterward, if you feel like you connected with someone senior, send them a follow-up email saying it was nice to meet them, says Ms. Pachter. "What have you got to lose?" 【R5】______ Holiday parties are one of the few workplace events where imbibing is allowed and even encouraged to get people relaxed. However, just because alcohol is free-flowing at the bar doesn't mean you should take that as a license to reprise your college frat parties. "Most people head toward the bar and the buffet when they get to a holiday party, and if they drink on an empty stomach they tend to get inebriated and then they could say the wrong thing or do the wrong thing," says Ms. Whitmore. "No. 1 rule is: Don't drink too much, monitor your alcohol intake. Usually, one or two drinks is plenty."

Many of the tech industry' s biggest companies, like Amazon, Google, IBM and Microsoft, are jockeying to become the leader for artificial intelligence(A.I.). In the industry's term, the companies are engaged in a "platform war." A platform, in technology, is essentially a piece of software that other companies build on and that consumers cannot do without. Become the platform and huge profits will follow. Microsoft dominated personal computers because its Windows software became the center of the consumer software world. Google has come to dominate the Internet through its ubiquitous search bar. If true believers in A.I. are correct that this long-promised technology is ready for the mainstream, the company that controls A.I. could steer the tech industry for years to come. "Whoever wins this race will dominate the next stage of the information age," said Pedro Domingos, a machine learning specialist and the author of "The Master Algorithm," a 2015 book that contends that A.I. and big-data technology will remake the world. In this fight—no doubt in its early stages—the big tech companies are engaged in tit-for-tat publicity stunts, circling the same start-ups that could provide the technology pieces they are missing and, perhaps most important, trying to hire the same brains. Fei-Fei Li, a Stanford University professor who is an expert in computer vision, said one of her Ph.D. candidates had an offer for a job paying more than $1 million a year, and that was only one of four from big and small companies. For years, tech companies have used man-versus-machine competitions to show they are making progress on A.I. In 1997, an IBM computer beat the chess champion Garry Kasparov. Five years ago, IBM went even further when its Watson system won a three-day match on the television trivia show "Jeopardy!" Today, Watson is the centerpiece of IBM's A.I. efforts. By 2020, the market for machine learning applications will reach $40 billion, IDC, a market research firm, estimates. And 60 percent of those applications, the firm predicts, will run on the platform software of four companies—Amazon, Google, IBM and Microsoft. Intelligent software applications will become commonplace, said Jeff Dean, a computer scientist who oversees Google's A.I. development. "And machine learning will touch every industry."

Scientists say they have found a way to turn body fat into a better type of fat that burns off calories and weight. The US Johns Hopkins team made the【C1】______in rats but believe the same could be done in humans, offering the hope of a new way to treat obesity. 【C2】______the expression of a protein linked to【C3】______not only reduced the animals' calorie intake and weight, but also【C4】______their fat composition. Brown fat is【C5】______in babies, which they use as a【C6】______source to generate body heat,【C7】______calories at the same time. But as we age our brown fat largely【C8】______and gets replaced by "bad" white fat, which【C9】______sits as a spare tyre around the waist. "We will need a lot more work to tease this out, but it could offer a(n)【C10】______way to develop new treatments for obesity", an expert said. Experts have【C11】______that stimulating the body to make more brown fat【C12】______white fat could be a helpful way to control weight and【C13】______obesity and its related health problems. Various teams have been searching for a way to do this, and Dr Sheng Bi and colleagues at the Johns Hopkins University School of Medicine believe they may have cracked it. They designed an experiment to see【C14】______suppressing an appetite-stimulating protein called NPY would decrease body weight in rats. When they silenced NPY in the brains of the rats they found their appetite and food【C15】______decreased. Even when the rats were fed a very【C16】______, high-fat diet they still managed to keep more weight【C17】______than rats who had fully functioning NPY. The scientists then checked the fat【C18】______of the rats and found an interesting change had occurred. In the rats with silenced NPY expression, some of the bad white fat had been replaced with good brown fat. The researchers are【C19】______that it may be possible to achieve the same effect in people by injecting brown fat stem cells【C20】______the skin to burn white fat and stimulate weight loss.

Much of continental Europe is in poor shape. True, the aggregate wealth of people is little changed and the social capital in museums, parks and other amenities is still intact. Yet, in the western part, the economy is failing society. Inclusion of ethnic minorities and youth in the economy is more lacking than ever. Among those who do participate, fewer are prospering. It is a measure of the decline that, in almost every country, the growth of wage rates has steadily slowed since 1995. What has gone wrong? European economists speak of a loss of competitiveness in southern Europe. They suggest that output and employment are down, relative to the past trend, because wages leapt ahead of productivity, making labour too expensive and forcing employers to cut back. Taking this perspective, some German economists argue that wages need to fall in the affected economies. Others argue instead for monetary stimulus—for instance, asset purchases by central banks—to raise prices and make current wage rates affordable. Economists of a classical bent lay a large part of the decline of employment, and thus lagging output, to a contraction of labour supply. And they lay that contraction largely to outbreaks of fiscal profligacy—as happened in Europe from the mid-1990s to the mid-2000s. Disciples of Keynes, who focus on aggregate demand, view any increase in household wealth as raising employment because they say it adds to consumer demand. They say Europe needs a lot more fiscal "profligacy" if it is to bring unemployment down. Some evidence favours the classics. Yet both sides of this debate miss the critical force at work. The main cause of Europe's deep fall—the losses of inclusion, job satisfaction and wage growth—is the devastating slowdown of productivity that began in the late 1990s and struck large swathes of the continent. It holds down the growth of wages rates and it depresses employment. That slowdown resulted from narrowing innovation. Even in the postwar years, innovation in Europe was feeble by past standards. In the aftermath of the financial crisis, much of Europe is still suffering a slump on top of its post-1990s fall. The slump will pass but the fall will not be easily overcome. The continent is losing its best talent. It needs to fight for an economic life worth living.

[A]Polite High-tech Circles [B]The European Solution [C]Recycling and Reuse [D]Disposal Crisis of E-waste [E]Public Health Problems [F]The US Is Taking Action [G]Going Global It's long been known, but little discussed in polite high-tech circles, that information-age technology is not the clean industry it claims to be. Manufacturing a single PC can generate 139 pounds of waste and involves chemicals linked to high rates of cancer and birth defects among workers and communities. 【R1】______ Electronic waste (e-waste)—such as obsolete and discarded computers, monitors, printers, cell phones, and televisions—is one of the fastest growing waste streams in the developed world, thanks to the industry's philosophy of "design for immediate obsolescence" and an anemic electronics-recycling infrastructure. An estimated 300 to 500 million computers have descended on landfills by 2007 in the US alone. Three-quarters of all computers ever sold in this country await disposal in garages and storage facilities because their owners don't know what to do with them. 【R2】______ If the full force of the high-tech revolution hits the landfill, its health risks will leave no community untouched. E-waste accounts for 5 percent of all solid waste in America but approximately 40 percent of the lead, 70 percent of the heavy metals, and a significant portion of the organic chemical pollutants in America's dumps. This e-waste can leach into the ground, as it did in the Silicon Valley. It was the widespread contamination of the valley's aquifers in the early 1980s that initially punctured the high-tech industry's clean image. Currently, there are more EPA Superfund clean-up sites in this valley than anywhere else in the US. The threat of soil and drinking water contamination will grow as e-waste surges into the waste stream worldwide. 【R3】______ The European Union is way ahead of the US in recognizing the hazards and moving towards a solution. The first European Union directive on e-waste, adopted last year, requires producers to take responsibility for the entire life cycle of their products. By 2005, companies will either have to take back products directly from consumers or fund independent collectors to do so. Waste that was generated prior to the enactment date will be the responsibility of all existing companies, in proportion to their market share. Future waste is to be the individual responsibility of each company, thereby creating an incentive to redesign products for easier and safer recycling and disposal. No e-waste will be allowed in municipal waste streams. 【R4】______ Because the US high-tech industry and its friends in Washington represent the biggest obstacles to the globalization of take-back laws, a broad coalition of environmental, health, labor, and recycling groups and local governments has formed the Computer Take Back Campaign to support EU-style legislation in the US. Hundreds of organizations and local governments in the US have already endorsed the campaign' s platform. The campaign advocates that the US adopt standards for electronics manufacturers at least as stringent as those adopted by the EU: hazardous materials would be phased out, and all electronics would be designed for reuse and recycling. 【R5】______ The European approach is more than a minor "software patch" on a fundamentally flawed program. By establishing corporate responsibility for products at the end of their useful lives, this strategy could have wide-ranging effects on the information technology industry. The EU approach spreads environmental benefits. If we can adopt the EU's code in the US, we can do a bit of reverse engineering on globalization. By downloading Europe's program to the US, we can finally begin to clean up the "clean industry" around the globe.

Yawning can be a problem at the office for Lindsay Eierman, which makes her embarrassed. "I've explained, 'I'm sorry, I didn't get much sleep last night,'" says Ms Eierman, a 26-year-old social worker from Durham, North Carolina. But a lack of sleep may not be the problem. Researchers are starting to unravel the mystery surrounding the yawn, one of the most common and often embarrassing behaviours. Yawning, they have discovered, is much more complicated than previously thought. Although all yawns look the same, they appear to have many different causes and to serve a variety of functions. Yawning is believed to be a means to keep our brains alert in times of stress. Contagious yawning appears to have evolved in many animal species as a way to protect family and friends, by keeping everyone in the group vigilant. Changes in brain chemistry trigger yawns, which typically last about six seconds and often occur in clusters. To unravel the mystery of yawning, scientists built upon early, observed clues. Yawning tends to occur more in summer. Most people yawn upon seeing someone else do it, but infants and people with autism or schizophrenia aren't so affected by this contagion effect. And certain people yawn at surprising times, like parachutists who are about to jump out of a plane or Olympic athletes getting ready to compete. A leading hypothesis is that yawning plays an important role in keeping the brain at its cool, optimal working temperature. The brain is particularly sensitive to overheating, according to Andrew Gallup, an assistant professor of psychology at the State University of New York at Oneonta. Reaction times slow and memory wanes when the brain' s temperature varies even less than a degree from the ideal 98.6 degrees Fahrenheit. There are some practical applications. Dr. Gallup said managers might want to keep in mind the brain-cooling role of yawning when a meeting is long and boring. "One way to diminish yawning frequency in an office would be to keep it air-conditioned. If it' s very cold in the room, yawning rates are going to be quite low," Dr. Gallup said.

Australian children are visiting social media websites at an increasingly younger age, a new survey suggests, with one in five "tweens" (children between the ages of about 10 and 14) admitting they have chatted to someone online they do not know. The report "Tweens, Teens and Technology" by online security company McAfee found that children in the tweens age【C1】______of 8 to 12 were【C2】______technology faster than expected, with 67 percent using a social media website..【C3】______the age eligibility for Facebook being 13, one in four (26 percent)【C4】______using the site— although 95 percent said they had their parents"【C5】______to do so. The most【C6】______site for tweens was Skype (used by 28 percent),【C7】______children were also using Instagram, according to the survey of 500 youngsters geographically【C8】______of Australia"s online population.【C9】______the survey found that one in five tweens (19 percent) said they chatted to someone online that they did not know,【C10】______seven percent said they had shared personal information.

Economics is an important component of the core MBA curriculum because economic principles are behind almost all managerial activities. Economists at business schools research and teach about how markets work; how scarce resources get produced, consumed and allocated; and how various participants in the economy make optimal decisions. These issues will be relevant to managers in virtually all aspects of their work for the rest of their careers. This is true both at the broadest levels—such as strategic management, finance, organizational design, human resources, and managing global organizations—and also when they drill down into more specific areas, such as optimizing prices, setting employee compensation, and analyzing how modern managerial practices affect a firm's performance. One rapidly growing area of economics that has received a lot of attention from business-school economists is market design. Traditionally, economists studied the properties of existing market institutions. More recently, however, they have taken an active role, and have applied economic analysis to design new markets or to improve existing ones.

For hundreds of millions of years, turtles(海龟) have struggled out of the sea to lay their eggs on sandy beaches, long before there were nature documentaries to celebrate them, or GPS satellites and marine biologists to track them, or volunteers to hand-carry the hatchlings (幼龟) down to the water's edge lest they become disoriented by headlights and crawl towards a motel parking lot instead. A formidable wall of bureaucracy has been erected to protect their prime nesting sites on the Atlantic coastlines. With all that attention paid to them, you'd think these creatures would at least have the gratitude not to go extinct. But Nature is indifferent to human notions of fairness, and a report by the Fish and Wildlife Service showed a worrisome drop in the populations of several species of North Atlantic sea turtles, notably loggerheads(红海龟) , which can grow to as much as 400 pounds. The South Florida nesting population, the largest, has declined by 50% in the last decade, according to Elizabeth Griffin, a marine biologist with the environmental group Oceana. The figures prompted Oceana to petition the government to upgrade the level of protection for the North Atlantic loggerheads from "threatened" to "endangered"—meaning they are in danger of disappearing without additional help. Which raises the obvious question; what else do these turtles want from us, anyway? It turns out, according to Griffin, that while we have done a good job of protecting the turtles for the weeks they spend on land (as egg-laying females, as eggs and as hatchlings) , we have neglected the years they spend in the ocean. "The threat is from commercial fishing," says Griffin. Trawlers (which drag large nets through the water and along the ocean floor) and long-line fishers (which can deploy thousands of hooks on lines that can stretch for miles) take a heavy toll(损失) on turtles. Of course, like every other environmental issue today, this is playing out against the background of global warming and human interference with natural ecosystems. The narrow strips of beach on which the turtles lay their eggs are being squeezed on one side by development and on the other by the threat of rising sea levels as the oceans warm. Ultimately we must get a handle on those issues as well, or a creature that outlived the dinosaurs (恐龙) will meet its end at the hands of humans, leaving our descendants to wonder how a creature so ugly could have won so much affection.

The casino(赌场)at the smart Atlantis resort on Paradise Island in the Bahamas is bigger than 20 tennis courts. Tourists flit from slot machine to roulette table, drift past Temples of the Sun and Moon and walk by Crystal Gate and Poseidon"s Throne. But the only Bahamians in sight are waiters, croupier and cashiers. The Bahamas legalised casino gambling in 1969, when they were still a British colony. But mainly because of the influence of local pastors, both Bahamians and foreigners who live in the country are banned from gambling. This has not stopped residents from placing bets. Instead, they gamble off the books in " number houses" or "webshops"—legal internet cafes that offer illegal bets on the side and operate in plain sight. These have mushroomed in recent years, even as tourism has stagnated and hotels have reduced staff. This pretence will be put to the test on January 28 th, when a referendum will be held on legalising gambling in web shops, as well as on a separate proposal to set up a national lottery. The well-funded campaign supporting the initiative has been distributing posters and T-shirts. It argues that web shops account for almost 2% of jobs in the country, and that gambling taxes could help close the budget deficit. The "no" movement, which calls itself "Save Our Bahamas" , is led by the islands" evangelical(新教会的)churches. Perry Christie, the prime minister, says he has "no horse in the race". The opposition accuses him, without proof, of running a "fixed" referendum on behalf of web-shop owners who back him financially. If the proposal is approved, the government will probably try to pass a series of reforms supported by the big hotel casinos. In order to compete with Las Vegas, New Jersey or Macau, they say, they need authorisation for credit-card payment for chips, online and mobile wagers, private VIP gaming rooms and betting on sports matches while play is in progress. They also want stronger legal tools to collect unpaid debts and the right to void payments caused by computer errors. The tourism minister has already announced support for these policies. However, letting Bahamians into the casinos is not yet on the agenda.
