单选题For years, researchers have struggled to understand why so many women leave careers inscience and engineering. Theories run the gamut (整个范围), from family-unfriendly work schedules to natural differences between the genders. A new paper by McGill University economist Jennifer Hunt offers another explanation: women leave such jobs when they feel disappointed about pay and the chance of promotion. Her first finding was that women actually don't leave jobs in science at an above average rate. The difference, Hunt found, comes from the engineering sector. That's not simply because women are exiting the workforce to raise families. About 21% of all graduates surveyed were working in a field unrelated to their highest college degree. That proportion held steady for both men and women. Yet in engineering, there was a gap. About 10% of male engineers were working in an unrelated field, while some 13% of female engineers were. Women who became engineers disproportionately left for other sectors. The survey suggests options such as working conditions, pay, promotion-opportunities, job location and family-related reasons. As it turned out, more than 60% of the women leaving engineering did so because of dissatisfaction with pay and promotion opportunities. More women than men left engineering for family-related reasons, but that gender gap was no different than what Hunt found in nonengineering professions. "It doesn't have anything to do with the nature of the work," says Hunt. The question then becomes why women engineers feel so stifled (窒息) when it comes to pay and promotion. Women also left fields such as financial management and economics at higher than expected rates. The commonality, like engineering, those sectors are male-dominated. Some 74% of financial-management degree holders in the survey sample were male. Men made up 73% of economics graduates. And to take one example from engineering, some 83% of mechanical-engineer grads were male. Jennifer Hunt concludes that focusing on making engineering jobs more family-friendly alone—by offering flexible work schedules, say—misses an important part of the mark. If we desire to keep women working as engineers, whether for their sakes or society's, then a better focus may be creating work environments where women feel more able to climb the career ladder.

单选题 White people tend to be nervous of raising the subject of race and education, but are often voluble on the issue if a black person brings it up. So when Trevor Phillips, chair man of Britain' s Commission for Racial Equality, said that there was a particular problem with black boys' performance at school, and that it might be a good idea to educate them apart from other pupils, there was a torrent of comment. Some of it commended his proposal, and some criticized it, but none of it questioned its premise. Everybody accepts that black boys are a problem. On the face of it, it looks as though Mr Phillips is right. Only 27% of Afro-Caribbean boys get five A-C grades at GCSE, the exams taken by 16-year-olds, compared with 47% of boys as a Whole and 44% of Afro-Caribbean girls. Since, in some subjects, candidates who score less than 50% get Cs, those who don' t reach this threshold have picked up pretty little at school. Mr Phillips' s suggestion that black boys should be taught separately implies that ethnicity and gender explain their underachievement. Certainly, maleness seems to be a disadvantage at school. That' s true for all ethnic groups: 57% of girls as a whole get five A-Cs, compared with 47% of boys. But it' s not so clear that blackness is at the root of the problem. Among children as a whole, Afro-Caribbeans do indeed perform badly. But Afro Caribbeans tend to be poor. So to get a better idea of whether race, rather than poverty, is the problem, one must control for economic status. The only way to do that, given the limits of British educational statistics, is to separate out the exam results of children who get free school meals: only the poor get free grub. Poor children' s results tell a rather different story. Afro-Caribbeans still do remark ably badly, but whites are at the bottom of the pile. All ethnic minority groups do better than them. Even Bangladeshis, a pretty deprived lot, do twice as well as the natives in their exams; Indians do better still. And absolute numbers of underperforming whites dwarf those of underperforming Afro-Caribbeans: last year, 131,393 of white boys failed to hit the government's benchmark, compared with 3,151 Afro-Caribbean boys. These figures suggest that, at school at least, black people' s problem is not so much race as poverty. And they undermine the idea of teaching black boys separately, for if poor whites are doing worse than poor blacks, there' s not much argument for singling out blacks for special measures: whites need help just as badly.

单选题{{B}}Text 4{{/B}} Want a glimpse of the future of health care? Take a look at the way the various networks of people involved in patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient—no matter where he or she may be. Online doctors offering advice based on standardized symptoms are the most obvious example. Increasingly, however, remote diagnosis (telemedicine) will be based on real physiological data from the actual patient. A group from the University of Kentucky has shown that by using an off-the-shelf PDA(personal data assistance) such as a Palm Pilot plus a mobile phone, it is perfectly feasible to transmit a patient's vital signs over the telephone. With this kind of equipment in a first-aid kit, the cry asking whether there was a doctor in the house could well be a thing of the past. Other medical technology groups are working on applying telemedicine to rural care. And at least one team wants to use telemedicine as a tool for disaster response—especially after earthquakes. Overall, the trend is towards providing global access to medical data and expertise. But there is one problem. Bandwidth is the limiting factor for transmitting complex medical images around the world—CT scans being one of the biggest bandwidth consumers. Communications satellites may be able to cope with the short-term needs during disasters such as earthquakes, wars or famines. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of distributed medical intelligence. Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should usher in an era when telemedicine and the sharing of medical information, expert opinion and diagnosis are common.

单选题Social-networking sites offer users easy ways to present idealized images of themselves, even if those ideals don"t always square with their real-world personalities. Psychology researcher Soraya Mehdizadeh has discovered a way to poke through the offline-online curtain: she has used Faeebook to predict a person"s level of narcissism and self-esteem. Mehdizadeh, who conducted the study as an undergraduate at Toronto"s York University, gained access to the Faeebook accounts of 100 college students and measured activities like photo sharing, wall postings and status updates; she also studied how frequently users logged on and how often they remained online during each session. Her findings were published recently in Cyberpsyehology, Behavior and Social Networking. After measuring each subject using the Narcissism Personality Inventory and Rosenberg Self-Esteem Scale, Mehdizadeh, who graduated from York this past spring, discovered narcissists and people with lower self-esteem were more likely to spend more than an hour a day on Facebook and were more prone to post self-promo-tional photos ( striking a pose or using Photoshop, for example). Narcissists were also more likely to showcase themselves through status updates (using phrases like "I"m so glamorous I bleed glitter") and wall activity (posting self-serving links like " My Celebrity Look-alikes" ). Self-esteem and narcissism are often interrelated but don"t always go hand in hand. Some psychologists believe that narcissists--those who have a pervasive pattern of grandiosity, a need for admiration, as well as a lack of sympathy--unconsciously inflate their sense of self-importance as a defense against feeling inadequate. Not enough empirical research has been produced to confirm that link, although Mehdizadeh"s study seems to support it. Because narcissists have less capacity to sustain intimate or long-term relationships, Mehdizadeh thinks that they would be more drawn to the online world of virtual friends and emotionally detached communication. Although it seems that Facebook can be used by narcissists to fuel their inflated egos, Mehdizadeh stops short of proclaiming that excessive time spent on Faeebook can turn regular users into narcissists. She also notes that social-networking sites might ultimately be found to have positive effects when used by people with low self-esteem or depression. "If individuals with lower self-esteem are more prone to using Facebook," she says, "the question becomes, " Can Facebook help raise self- esteem by allowing patients to talk to each other and help each other in a socially interactive environment?" I don"t think it"s necessarily a bad thing that people with low self-esteem use Facebook. "

单选题{{B}}Text 3{{/B}} After World War Ⅱ the glorification of an ever-larger GNP formed the basis of a new materialism, which became a sacred obligation for all Japanese governments, businesses and trade unions. Anyone who mentioned the undesirable by-products of rapid economic growth was treated as a heretic. Consequently, everything possible was done to make conditions easy for the manufacturers. Few dared question the wisdom of discharging untreated waste into the nearest water body or untreated smoke into the atmosphere. This silence was maintained by union leaders as well as by most of the country's radicals; except for a few isolated voices, no one protested. An insistence on treatment of the various effluents would have necessitated expenditures on treatment equipment that in turn would have given rise to higher operating costs. Obviously, this would have meant higher prices for Japanese goods, and ultimately fewer sales and lower industrial growth and GNP. The pursuit of nothing but economic growth is illustrated by the response of the Japanese government to the American educational mission that visited Japan in 1947. After surveying Japan's educational program, the Americans suggested that the Japanese fill in their curriculum gap by creating departments in chemical and sanitary engineering. Immediately, chemical engineering departments were established in all the country's universities and technical institutions. In contrast, the recommendation to form sanitary engineering departments was more or less ignored, because they could bring no profit. By 1960, only two second-rate universities, Kyoto and Hokkaido, were interested enough to open such departments. The reluctance to divert funds from production to conservation is explanation enough for a certain degree of pollution, but the situation was made worse by the type of technology the Japanese chose to adopt for their industrial expansion. For the most part, they simply copied American industrial methods. This meant that methods originally designed for use in a country that stretched from the Atlantic to the Pacific with lots of air and water to use as sewage receptacles were adopted for an area a fraction of the size. Moreover, the Japanese diet was much more dependent on water as a source of fish and as an input in the irrigation of rice; consequently discharged wastes built up much more rapidly, in the food chain.
