单选题Hawaii's native minority is demanding a greater degree of sovereignty over its own affairs. But much of the archipelago's political establishment, which includes the White Americans who dominated until the Second World War and people of Japanese, Chinese and Filipino origin, is opposed to the idea. The islands were annexed by the US in 1898 and since then Hawaii's native peoples have fared worse than any of its other ethnic groups. They make up over 60 percent of the state's homeless, suffer higher levels of unemployment and their life span is five years less than the average Hawaiians. They are the only major US native group without some degree of autonomy. But a sovereignty advisory committee set up by Hawaii's first native governor, John Waihee, has given the natives' cause a major boost by recommending that the Hawaiian natives decide by themselves whether to re-establish a sovereign Hawaiian nation. However, the Hawaiian natives are not united in their demands. Some just want greater autonomy with the state—as enjoyed by many American Indian natives over matters such as education. This is a position supported by the Office of Hawaiian Affairs (OHA), a state agency set up in 1978 to represent to natives' interests and which has now become the moderate face of the native sovereignty movement. More ambitious in the Ka Lahui group, which declared itself a new nation in 1987 and wants full, official independence from the US. But if Hawaiian natives are given greater autonomy, it is far from clear how many people this will apply to. The state authorities only count those people with more than 50 percent Hawaiian blood as native. Native demands are not just based on political grievances, though. They also want their claim on 660,000 hectares of Hawaiian crown land to be accepted. It is on this issue that native groups are facing most opposition from the state authorities. In 1933, the state government paid the OHA US $136 million in back rent on the crown land and many officials say that by accepting this payment the agency has given up its claims to legally own the land. The OHA has vigorously disputed this.

单选题What we don"t know about kids and television could fill a weeklong miniseries. Given worries about everything from childhood obesity to scholastic shortcomings, it"s high time to find out. But before Congress approves $20 million a year to research children and the media, it should get more specific assurances that the money will pay for comprehensive, high-quality studies instead of bits of teasing information. Up to now, a patchwork of research on kids and TV has yielded plenty of suspicion but little real knowledge. Yes, a study two years ago found that teenagers who watched a lot of TV tended to be more aggressive. But what does that mean? Maybe more-aggressive kids are drawn more to TV. Ditto for the April study about preschoolers who watch hours of TV tending to have attention-span problems later on. It"s possible that children with a propensity toward attention problems are drawn more to that jumpy on-screen world in the first place. For better or worse, U.S. kids spend a lot of time in front of a TV or computer screen, two hours daily for those 5 and younger. If the schools spent two hours a day on a single activity, there would be intense concern about its value. So there is worth in legislation by Sen. Joe Lieberman to provide $100 million over five years for research on child development and electronic media. A scientific panel would set up a list of the key issues to be studied and review grant applications from universities or nonprofit institutes. This centralized approach makes sense—especially considering the money involved. Good studies are costly, and there haven"t been enough of them on this subject. Merely showing a link between TV viewing and a certain behavior doesn"t prove anything. In addition to the possibility the behavior is causing the TV watching instead of the other way around, a third factor could be causing both. Only carefully controlled studies obtain worthwhile results. At their best, such studies might tell us whether educational computer games for toddlers interrupt the natural development of the brain instead of aiding it, or whether seeing Ronald McDonald cavort on a soccer field makes a child more active or just more likely to crave French fries. Parents could decide limits based on more than instinct. But before spending the money, Congress should insist on a quality of research that will give the public answers about TV instead of more arguments. This shouldn"t be a handout to think tanks for more mushy research on a complicated but vital issue.

单选题 On the high-speed train from Avignon (阿维尼翁) to Paris, my husband and I landed in the only remaining seats on the train, in the middle of a car, directly opposite a Frenchwoman of middle years. It was an extremely uncomfortable arrangement to be looking straight into the eyes of a stranger. My husband and I pulled out books. The woman produced a large makeup case and proceeded to freshen up. Except for a lunch break, she continued this activity for the entire three-hour trip. Every once in a while she surveyed the car with a bright-eyed glance, but never once did she catch my (admittedly fascinated) eye. My husband and I could have been a blank wall. I was amused, but some people would have felt insulted, even repulsed (厌恶的). There is something about primping in public that calls up strong emotional reactions. Partly it's a question of hygiene. (Nearly everyone agrees that nail-paling and hair-combing are socially considered unwise to do.) And it's a matter of degree. Grooming-a private act-has a way of negating the presence of others. I was once seated at a party with a model-actress who immediately waved a silly brush and began dusting her face at the table, demonstrating that while she was next to me, she was not with me. In fact, I am generally inhibited from this maneuver in public, except when I am in the company of cosmetics executives (when it's considered unpleasant not to do it) or my female friends when it's a fun just-us-girls moment. In a gathering more professional than social, I would refrain. Kathy Peiss, a history professor at the University of Massachusetts in Amherst and an authority on American beauty rituals, says that nose-powdering in the office was an occasion for outrage in 1920's and 30's. Deploring the practice as a waste of company time, trade journals advised managers to discourage it among clerical workers. But how much time could it take? Certainly the concern was out of proportion with the number of minutes lost Peiss theorizes that it was the blatant assertion of a female practice in what had been an all-male province that disturbed critics. Peiss tells me that after the 30's, pulling out a compact was no longer an issue. It became an accepted practice. I ask if she feels free to apply lipstick at a professional lunch herself. Sounding mildly shocked, she says she would save that for the privacy of her car' afterward. Why? Because it would be 'a gesture of inappropriate femininity.' One guess is that most professional women feel this way. There is evidence of the popularity of the new lipsticks that remain in place all day without retouching. It's amazing to think that in our talk-show society, where every sexual practice is openly discussed, a simple sex-specific gesture could still have the power to disturb. The move belongs in the female arsenal and, like weapons, must be used with caution.

单选题Protection of the environment is based on a principle that is beginning to be used in the field of jurisprudence. The principle has to do with property rights. The idea is that we all have a property right in the air and water around us. If a business firm pollutes that air or water, their act in so doing constitutes damage to something we own—just as if the firm had dropped a smoke bomb down our chimney. Our legal ease against such a firm is then baaed on the complaint that we deserve compensation for an infringement of our right to use our private property as we please ( provided we don' t interfere with the same rights of a neighbor). Assuming we win the case, the offending firm then has to pay us for damaging our property—the air or water we "own". And so protection of the environment, specifically the control of pollution, now rests on the idea that we, as members of the public, share a right to clean air and water and to the good health that clean air and water quality can give us. But, as always, costs and benefits are involved in any decision to improve the environment. In an Adam Smithian, self-interested world, entrepreneurs or businessmen are expected to increase their profits as much as possible. The natural way to do this is to produce at the lowest possible cost. But at whose cost? It is obviously cheaper for entrepreneurs to dump waste into the nearest stream or into the atmosphere than to truck it to some waste disposal facility or to filter it as it comes out of smokestacks. Therefore, what may be sensible for entrepreneurs may not be desirable for the community. Here is a classic trade-off: When the government intervenes to force entrepreneurs to stop polluting, entrepreneurs have to adopt more expensive means of production or waste disposal. Inevitably, they will charge higher prices, and, given no change in demand, the quantity demanded will drop and workers will be laid off. The trade-off is therefore cleaner air and water or more unemployment. This is how economists view this problem.
