18、 assumption of orthodox (传统的) economics, where it is thought to lead to benefits for the economy as a whole. It is what the 18th-centuiy Scottish economist Adam Smith described as the “invisible hand“. But evolutionary biologists have come to see cooperation and selflessness as a big part of our 1 a

19、s a species. During the course of our evolution, they point out, cooperative groups 2 outcompeted groups of cheats. So we are inherently cooperative when operating within our own groups. We have also 3 social mechanisms to reinforce actions that benefit the group. “You could say teamwork at the scal

20、e of small groups is the signature 4 of our species,“ says evolutionary biologist David Sloan Wilson from Binghamton University in New York. But 5 teamwork can include a competition mechanism to promote actions that benefit the group, particularly in larger groups. It“s also important; to remember t

21、hat in-group cooperation evolved partly in response to competition between groups. This evolutionary perspective is radically new to economics, and it could be relevant to grand-scale economic problems that require solutions involving cooperation between nations. Take the challenge of getting nation

22、s to work together over economic solutions to climate changea 6 focus in the run-up to climate negotiations in Paris, France, later this year. This is a gargantuan (巨大的) problem from any perspective, but it is 7 an issue of coordination for the sake of the common good at a massive scale, says Wilson

23、. “The challenge is therefore to 8 at larger scales the coordination and control that takes place more spontaneously at smaller scales,“ he saysfrom multicellular (多细胞的) organisms to village-sized groups of humans. “Morality evolved out of cooperation within and competition between groups, so when a

24、cting as a single group to tackle global problems we will have to 9 the role of natural selection ourselves,“ Wilson says. This might involve pursuing a wide variety of 10 , identifying those that work best, and then creating incentives to cooperate on implementation. “In some ways it“s the opposite

26、Your doctor could soon be prescribing crucial sleep as treatment for everything from obesity to mental health as experts say carving out time for sleep is just as important as diet and exercise. B. After being diagnosed with brain and lung cancer in 2011, Lynn Mitchell, 68, was averaging about an ho

27、ur of solid sleep a night. Stressed about her treatments, she was paying for it in hours of lost sleep. The brain cancer was already affecting her mobilityMitchell was often dizzy and would lose her balancebut the lack of sleep was making things worse. Even walking became increasingly difficult. Exh

28、austed in the mornings, she was practically incoherent. When her doctors recommended she see a sleep therapist, Mitchell was relieved at how benign it sounded in comparison to the chemotherapy (化疗) she had undergone, which had side effects like nausea and fatigue. C. For about nine weeks, Mitchell w

29、orked with the sleep therapist to adjust her sleep habits. She got under the covers only when she was extremely tired. She quit watching TV in bed. She stopped drinking caffeinated coffee in the evening. She also learned breathing exercises to relax and help her drift off. It was all quite simple an

30、d common sense, and, most importantly, noninvasive and didn“t require popping any pills. D. “It“s common knowledge that sleep is needed for day-to-day function,“ says Dr. David Rapoport, director of the Sleep Medicine Program at NYU School of Medicine. “What isn“t common knowledge is that it really

31、mattersit“s not just cosmetic.“ Rapoport has long seen people seek sleep therapy because they“re chronically tired or suffering from insomnia (失眠),but an increasing number of patients are being referred to his center for common diseases, disorders, and mental health. E. Researchers have known for so

32、me time that sleep is critical for weight maintenance and hormone balance. And too little sleep is linked to everything from diabetes to heart disease to depression. Recently, the research on sleep has been overwhelming, with mounting evidence that it plays a role in nearly every aspect of health. B

33、eyond chronic illnesses, a child“s behavioral problems at school could be rooted in mild sleep apnea (睡眠呼吸中止症). And studies have shown children with ADHD (注意力缺损多动障碍) are more likely to get insufficient sleep. A recent study published in the journal SLEEP found a link between older men with poor slee

34、p quality and cognitive decline. Another study out this week shows sleep is essential in early childhood for development, learning, and the formation and retention of memories. Dr. Allan Rechtschaffen, a pioneer of sleep research at the University of Chicago, once said, “If sleep does not serve an a

35、bsolutely vital function, then it is the biggest mistake the evolutionary process ever made.“ F. But to many of us, sleep is easily sacrificed, especially since lack of it isn“t seen as life threatening. Over time, sleep deprivation can have serious consequences, but we mostly sacrifice a night of s

36、leep here and there, and always say that we“ll “catch up“. Luckily, it is possible to make up for sleep debt (though it can take a very long time), but most Americans are still chronically sleep deprived. G. While diet and exercise have been a part of public health messaging for decades, doctors and

37、 health advocates are now beginning to argue that getting quality sleep may be just as important for overall health. “Sleep is probably easier to change than diet or exercise,“ says Dr. Michael Grandner, a sleep researcher at the University of Pennsylvania. “It may also give you more of an immediate

38、 reward if it helps you get through your day.“ And while there“s more evidence linking diet and exercise as influential health factors, sleep is probably more important in terms of brain and hormonal function, Grandner says. “Among a small group of sleep researchers, if it is always been said that e

39、ating, exercise, and sleep are the three pillars of health,“ says Dr. Rapoport. H. In our increasingly professional and digital lives, where there are now more things than ever competing for the horns in our day, carving out time for sleep is not only increasingly difficult, but also more necessary.

40、 Using technology before bed stimulates us and interferes with our sleep, yet 95% of Americans use some type of electronics like a computer, TV, or cell phone at least a few nights a week within the hour before we go to bed, according to a 2011 National Sleep Foundation survey. “Many doctors, lawyer

41、s, and executives stay up late and get up early and burn the candle at both ends,“ says Dr. Richard Lang, chair of Preventative Medicine at the Cleveland Clinic. “Making sure they pay attention to sleep in the same way they pay attention to diet and exercise is crucial.“ I. To some, sleep has become

42、 a powerful medicine to mental health. Arianna Huffington, president and editor-in-chief of the Huffington Post Media Group, advocates that sleep is the secret to success, happiness, and peak performance. After passing out a few years ago from exhaustion and cracking a cheekbone (颧骨) against her des

43、k, Huffington has become something of a sleep promoter. In a 2010 TED Women conference, Huffington said, “The way to a more productive, more inspired, more joyful life is getting enough sleep.“ Research linking high-quality sleep with better mental health is growing; a 2013 study found that treating

44、 depressed patients for insomnia can double their likelihood of overcoming the disorder. J. While 70% of physicians agree that inadequate sleep is a major health problem, only 43% counsel their patients on the benefits of adequate sleep. But there“s growing pressure on primary care physicians to add

45、ress, and even prescribe, sleep during routine check-ups. In a recent study published in the journal The Lancet Diabetes people with high-esteem do not think they“re better than others. According to his research, the more narcissistic children did not necessarily express more self-confidence. “Rathe

46、r than raising self-esteem, overvaluing practices may inadvertently raise levels of narcissism,“ Brummelman said. Over two years, the team evaluated 565 children in the Netherlands who were between the ages of 7 and 11 years old when the study began. They asked parents how much they agreed with stat

47、ements like, “My child is a great example for other children to follow,“ and whether or not they believed their children would have knowledge of various historical and cultural figures and topics, like “Neil Armstrong.“ Eventually, the researchers began including entirely fictional figures and topic

48、s, “Queen Alberta.“ The parents raising little narcissists would often fall for it. “Overvaluing parents tended to claim that their children had knowledge of many different topicseven these nonexistent ones,“ Brummelman said. While parental “overvaluing“ was associated with narcissistic offspring, p

49、arental warmth was not. Children of parents who expressed warmth by telling their children they loved them, but who did not engage in “overvaluing“ behavior, were more likely to agree with statements that suggested they were “happy with themselves as a person and liked the kind of person they were.“ In short, parental warmth appears to be closely linked to self-confident kids, not narcissistic kids. The researchers conclude that expressing warmth is key to promoting healthy self-confidence in c
