单选题There are many good reasons for great current attention to university-industry relations, but there are troublesome reasons as well. One is that universities are now unusually hungry. There is nothing wrong with hunger. But a hungry man may cut comers in his rush to nourishment, and he may be taken advantage of in negotiations. Fear of this is leading to the threat of protectionism, as exemplified by recent attempts to classify or otherwise control access to university research, including that joint with industry. In designing university-industry connections, protecting interests by high-level negotiations is wrong. Protectionism is dangerous and habit-forming. Circumstances exist where it is appropriate, but only for a short time. One of the few essentials of agreements is that any secrecy or interference with open publication or student interaction should be strictly temporary. The dominant problem of supporting enough basic research in universities will remain. This must continue to be a federal responsibility; no company or industry can harvest the results soon enough to justify any investment larger than keeping a window on basic research and conduit for the movement of bright young people into the company. Hard work in the universities will lead to important cooperative research agreements with industry, but unremitting effort will be required to maintain or enlarge the basic research on which all else rests. But there is far more at stake than support for universities. University-industry interaction should not be looked upon as support at all, but as an absolutely necessary part of the survival both of American institutions and of the American economy. As the economy stumbles, protectionism of all kinds becomes rampant, and everyone loses. From the university's standpoint, cooperative projects with industry affect graduate (and even undergraduate) work in healthy ways. To use Harvey Brooks's phrase, giving students "respect for applied problems" is an important part of their education. Wisdom begins when students (and even professors) realize that an invention is not a product and a product is not an industry. What is perhaps most at stake is attracting some of the ablest young people to those fields that can make a difference in the survival of our society. Particle physics ought to be done, just as art galleries ought to be maintained, and the richer the country is the more particle physics and art galleries it should support. But it would be a disaster if protectionism, of either the government or the industry variety, were to discourage some of the best young people from going into applied fields.
单选题Many people have been keeping on diet in the belief that cutting fat automatically cuts the risk of heart disease and cancer, too. Not so, says research published last week in the Journal of the American Medical Association. Women who trimmed the fat from their diets were just as vulnerable to colon cancer, breast cancer, and heart disease as women who did not.
The message? A low-fat diet isn"t equivalent to a healthful diet, says Marcia Stefanick, a physiologist at Stanford University"s Prevention Research Center, who helped run the government-sponsored study. Some 49,000 women between age 50 and 79 were divided into two groups and followed for an average of about eight years as part of the Women"s Health Initiative. One group was instructed to cut fat intake to 20 percent of total calories and to eat at least five daily servings of fruits and vegetables and six of grains. The other women were left to eat as they pleased. In the end, both groups had about the same occurrence of colorectal cancer, stroke, and heart disease. A slight difference in the rate of breast cancer among the lower-fat-diet women might be explained by chance alone.
There is hardly a green light to go on a junk-food binge, though, researchers" caution. For one thing, the women on the diet didn"t hit their target; they whittled fat intake just to 29 percent—from about 35 percent—by the end of the sixth year of the study. Moreover, the recommended diet made no distinction between "good" unsaturated fats and "bad" saturated fats and trans fats, whose importance to heart health has been recognized since the data-gathering started. And since all the women in the study were eating fairly healthfully beforehand, it"s possible that the small changes in vegetable and grain consumption by the dieting group weren"t big enough that any benefits registered. Rather than focus on total fat intake, Stefanick advises, go easy on foods containing saturated fats and trans fats and eat more vegetables and fruits and whole grains.
Long-term health may depend more on achieving a healthy body weight and getting regular exercise than on cutting out fat, says Tim Byers, an epidemiologist at the University of Colorado Health Sciences Center in Denver. Overweight people who "lower fat but don"t control calories can only make tiny changes to their chronic disease risk," he says. Until the links between disease and diet are fully understood, there are other ways to protect yourself: Get your cholesterol and blood pressure checked, and schedule that colonoscopy and mammogram. "No matter what you eat," says Byers, "a long life means knowing early where the problems lie."

单选题The truly incompetent may never know the depths of their own incompetence, a pair of social psychologists said on Thursday. "We found again and again that people who perform poorly relative to their peers tended to think that they did rather well," Justin Kruger, co-author of a study on the subject, said in a telephone interview. Kruger and co-author David Dunning found that when it came to a variety of skills — logical reasoning, grammar, even sense of humor — people who essentially were inept never realized it, while those who had some ability were self-critical. "It had little to do with innate modesty," Kruger said, "but rather with a central paradox: Incompetents lack the basic skills to evaluate their performance realistically. Once they get those skills, they know where they stand, even if that is at the bottom." "Americans and Western Europeans especially had an unrealistically sunny assessment of their own capabilities," Dunning said by telephone in a separate interview, "while Japanese and Koreans tended to give a reasonable assessment of their performance. In certain areas, such as athletic performance, which can be easily quantified, there is less self-delusion, the researchers said. But even in some cases in which the failure should seem obvious, the perpetrator is blithely unaware of the problem." This was especially true in the areas of logical reasoning, where research subjects — students at Cornell University, where the two researchers were based—often rated themselves highly even when they flubbed all questions in a reasoning test. Later, when the students were instructed in logical reasoning, they scored better on a test but rate themselves lower, having learned what constituted competence in this area. Grammar was another area in which objective knowledge was helpful in determining competence, but the more subjective area of humor posed different challenges, the researchers said. Participants were asked to rate how funny certain jokes were, and compare their responses with what an expert panel of comedians thought. On average, participants overestimated their sense of humor by about 16 percentage points. This might be thought of as the "above-average effect", the notion that most Americans would rate themselves as above average, a statistical impossibility. The researchers also conducted pilot studies of doctors and gun enthusiasts. The doctors overestimated how well they had performed on a test of medical diagnoses and the gun fanciers thought they knew more than they actually did about gun safety. So who should be trusted: The person who admits incompetence or the one who shows confidence? Neither, according to Dunning. "You can't take them at their word. You've got to take a look at their performance," Dunning added.
单选题Affluenza For many people, economic growth and an increase in possessions are signs of progress, but for anti-consumer groups overconsumption and materialism are sicknesses. A recent Public Broadcasting Service corned the term affluenza, which describes consumption of material goods in a strongly negative way. Af-flu-en-za (noun) combines two words: affluence and fluenza. According to anti-consumer and environmental fights organizations, the high consumption life styles of affluence cause people to be less happy even though they are acquiring more "things". The major negative effect on the environment is that overconsumption is depleting the world's natural resources, anti-consumer groups argue. Furthermore, the groups observe that an artificial, ongoing and insatiable quest for things and the money to buy them has replaced the normal desire for an adequate supply of life's necessities, community life, a stable family, and healthy relationships. For example, today's families are replacing items much more frequently than in the past. Many Americans now treat clothing as "disposable", discarding clothes when fashion changes, and creating a boom in thrift stores, and yard sales. The U.S.A.'s largest export is now used clothes. About 2.5 million tons of unfashionable old clothes and rags are sold to Third World countries every year.
单选题If income is transferred from rich persons to poor persons the proportion in which different sorts of goods and services are provided will be changed. Expensive luxuries will give place to more necessary articles, rare wines to meat and bread, new machines and factories to clothes and improved small dwellings; and there will be other changes of a like sort. In view of this fact, it is inexact to speak of a change in the distribution of the dividend in favor of, or adverse to, the poor. There is not a single definitely constituted heap of things coming into being each year and distributed now in one way, now in another. In fact, there is no such thing as the dividend from the point of view of both of two years, and therefore, there can be no such thing as a change in its distribution. This, however, is a point of words rather than of substance. What I mean when I say that the distribution of the dividend has changed in favor of the poor is that, the general productive power of the community being given, poor people are getting more of the things they want at the expense of rich people get ting less of the things they want. It might be thought at first sight that the only way in which this could happen would be through a transference of purchasing power from the rich to the poor. That, however, is not so. It is possible for the poor to be advantaged and the rich damaged, even though the quantity of purchasing power, i.e. of command over productive resources, held by both groups remains unaltered. This might happen if the technical methods of producing something predominatingly consumed by the poor were improved and at the same time those of producing something predominatingly consumed by tile rich were worsened, and if the net result was to leave the size of the national dividend as defined in Chapter V. unchanged. It might also happen if, by a system of rationing or some other device, the rich were forced to transfer their demand away from things which are important to the poor and which are produced under such conditions that diminished demand leads to lowered prices. Per contra——and this point will be seen in Part Ⅳ. To be very important practically——the share, both proportionate and absolute of command over the country's productive resources held by the poor may be increased, and yet, if the process by which they acquire this greater share involves an increase in the cost of things that play a large part in their own consumption, they may not really gain. Thus a change in distribution favorable to the poor may be brought about otherwise than by a transference of purchasing power, or command over productive resources, to them, and it does not mean a transference of these things to them. None the less, this sort of transference is the most important, and may be regarded as the typical, means by which changes in distribution favorable to the poor come about.
单选题One reason people believe physician-assisted suicide should be available for those who request it, is that people fear the loss of their autonomy. One source stated that more patients fear loss of control than they do actually suffer from a terminal illness. The Oregon Health Department said that "The fact that 79% of persons who chose physician-assisted suicide did not wait until they were bedridden to take their lethal medication provides further evidence that controlling the manner and time of death were important issues to these patients." Another reason for people to be in favor of physician-assisted suicide is some fear becoming a burden to their family or friends, and this makes people more susceptible to choosing assisted suicide, rather than letting a family member take care of them. Terminally ill patients feel guilty about having to have another person take care of them, instead of being able to take care of themselves and do things for themselves. "75% of those who asked for assistance in suicide fear burdening spouses and families." In the cases of Dr. Kevorkian, most of the female patients were more worried about becoming a burden to friends and family, while the males were more likely to commit suicide due to the suffering. Another issue is for the family to keep the patient alive, even if they are in a state of vegetation, because they fear living with the guilt of killing a member of their own family. The family members felt that if they did help in the assistance of the suicide, that they were abandoning the patient rather than helping with their final wishes, even in the cases of the patient only wanting the family to put them out of their misery. Most people that believe physician-assisted suicide should become a legal option for anyone who requests it, use the idea that everyone has the freedom of choice. In the book, Lawful Exit : The Limits of Freedom, Derek Humphry quotes Archibald MacLeish by saying, "Freedom is the right to choose the right to create for yourself the alternatives of choice. Without the possibility of choice and the exercise of choice, a man is not a man but a member, an instrument, a thing. " Another source states that, "Since there is no absolute legal, medical, or moral answer to the question of what constitutes a good or correct death in the face of a terminal illness, the power to make the decision about how someone dies can rest with only one individual—the person living in that particular body". There are many arguments in favor of assisted suicide, and the reality argument simply states that, people are already being helped into death, so why not just continue with it. Some people have even come as far as believing that since the democratic view is free of religion, suicide should be viewed as a pro, because those who see it as a negative issue, are seen as imposing their moral beliefs on everyone else. The patient's Right to Self-determination gives the patient the power to decide not only when they die, but also how, because it is in fact their body, their pain, and their life, so what's the point in keeping someone alive if they don't see any reason themselves. In a newspaper article one source states, "Proponents of assisted suicide always insist that the practice will be carefully limited. It will be available, they claim, only for those who request it and only for those who are dying, anyway". People do have a constitutional right to commit suicide, if they are impaired with a terminal illness that cannot be cured and they are unlikely to improve, as mentioned earlier in the paper. Another big issue that comes up in the discussion of assisted suicide, is people wanting to die with dignity. Dr. Christian Barnard states, "With an open-door approach to technical progress, with the emergence of candor in discussions of death-related subjects, with landmark changes in ethical and legal constraints to medical practice, I feel that society is ready to take a giant step toward a better understanding of the dignity of death and the attainment of that dignity, if necessary, through euthanasia and suicide." Some people have even gone as far as believing that euthanasia is the only merciful thing to do when patients are suffering and cannot be helped. People also believe that since sending criminals to prison is viewed as a positive idea, it should be acceptable to help those with terminal illnesses end their lives when they have done nothing wrong, but only want to help themselves.

单选题Do you think that all human beings have a "comfort zone" regulating the distance they stand from someone when they talk? This distance varies in interesting ways among people of different cultures. Greeks, others of the Eastern Mediterranean, and many of those from South America normally stand quite close together when they talk, often moving their faces even closer as they warm up in a conversation. North Americans find this awkward and often back away a few inches. Studies have found that they tend to feel most comfortable at about 21 inches apart. In much of Asia and Africa. there is even more space between two speakers in conversation. This greater space subtly lends an air of dignity and respect. This mater of space is nearly always unconscious, but it is interesting to observe. This difference applies also to the closeness with which people sit together, the extent to which they lean over one another in conversation, how they move as they argue or make an emphatic point. In the United States, for example, people try to keep their bodies apart even in a crowded elevator, in Paris they take it as it comes! Although North Americans have a relatively wide "comfort zone" for talking, they communicate a great deal with their hands — not only with gesture but also with touch. They put a sympathetic hand on a person's shoulder to demonstrate warmth of feeling or an arm around him in sympathy; they nudge a man in the ribs to emphasize a funny story; they put an arm in reassurance or stroke a child's head in affection; they readily take someone's arm to help him cross a street or direct him along an unfamiliar route. To many people — especially those from Asia or the Moslem countries — such bodily contact is unwelcome, especially if inadvertently done with the left hand. The left hand carries no special significance in the U. S. Many Americans are simply left-handed and use that hand more.
