单选题How many really suffer as a result of labor market problems? This is one of the most critical yet contentious social policy questions. In many ways, our social statistics exaggerate the degree of hardship. Unemployment does not have the same dire consequences today as it did in the 1930's when most of the unemployed were primary breadwinners, when income and earnings were usually much closer to the margin of subsistence, and when there were no countervailing social programs for those failing in the labor market. Increasing affluence, the rise of families with more than one wage earner, the growing predominance of secondary earners among the unemployed, and improved social welfare protection have unquestionably mitigated the consequences of joblessness. Earnings and income data also overstate the dimensions of hardship. Among the millions with hourly earnings at or below the minimum wage level, the over-whelming majority are from multiple earners, relatively affluent families. Most of those counted by the poverty statistics are elderly or handicapped or have family responsibilities which keep them out of the labor force, so the poverty statistics are by no means an accurate indicator of labor market pathologies. Yet there are also many ways our social statistics underestimate the degree of labor-market-related hardship. The unemployment counts exclude the millions of fully employed workers whose wages are so low that their families remain in poverty. Low wages and repeated or prolonged unemployment frequently interact to undermine the capacity for self-support. Since the number experiencing joblessness at some time during the year is several times the number unemployed in any month, those who suffer as a result of forced idleness can equal or exceed average annual unemployment, even though only a minority of the jobless in any month really suffer. For every person counted in the monthly unemployment tallies, there is another working part-time because of the inability to find fulltime work, or else outside the labor force but wanting a job. Finally, income transfers in our country have always focused on the elderly, disabled, and dependent, neglecting the needs of the working poor, so that the dramatic expansion of cash and in kind transfers does not necessarily mean that those failing in the labor market are adequately protected. As a result of such contradictory evidence, it is uncertain whether those suffering seriously as a result of thousands or the tens of millions, and, hence, whether high levels of joblessness can be tolerated or must be countered by job creation and economic stimulus. There is only one area of agreement in this debate—that the existing poverty, employment, and earnings statistics are inadequate for one of their primary applications, measuring the consequences of labor market problems.

单选题Psychologists______

单选题Ever since this government's term began, the attitude to teachers has been overshadowed by the mantra that good teachers cannot be rewarded if it means bad teachers are rewarded, too. That's why, despite the obvious need for them, big pay rises have not been awarded to teachers across the board. The latest pay rise was 3.6 percent--mad in the present situation. That's why, as well, the long battle over performance-related pay was fought as teacher numbers slid. The idea is that some kind of year zero can eventually be achieved whereby all the bad teachers are gone and only the good teachers remain. That is why the Government's attempts to relieve the teacher shortage have been so focused on offering incentives to get a new generation of teachers into training. The assumption is that so many of the teachers we have already are bad, that only by starting again can standards be raised. But the teacher shortage is not caused only because of a lack of new teachers coming into the profession. It is also because teaching has a retention problem, with many leaving the profession. These people have their reasons for doing so, which cannot be purely about wanting irresponsibly to "abandon" pupils more permanently. Such an exodus suggests that even beyond the hated union grandstanding, teachers are not happy. Unions and government appear to be in broad agreement that the shortage of teachers is a parlous state of affairs. Oddly, though, they don't seem entirely to agree that the reasons for this may lie in features of the profession itself and the way it is run. Instead, the Government is so suspicious of the idea that teachers may be able to represent themselves, that they have set up the General Teaching Council, a body that will represent teachers whether they want it to or not, and to which they have to pay ￡25 a year whether they want to or not. The attitudes of both sides promise to exacerbate rather than solve the problem. Teachers are certainly exacerbating the problem by stressing just how bad things are. Quite a few potential teachers must be put off. And while the Government has made quite a success of convincing the public that bad education is almost exclusively linked to bad teachers represented by destructive unions, it also seems appalling that in a survey last year, working hours for primary teachers averaged 53 hours per week, while secondary teachers clocked up 51 hours. At their spring conferences, the four major teaching unions intend to ballot their members on demanding from government an independent inquiry into working conditions. This follows the McCrone report in Scotland, which produced an agreement to limit hours to 35 per week, with a maximum class contact-time of 22 and a half hours. That sounds most attractive.

单选题From what Dr. Gleys Luke says, we may guess ______.

单选题Prince Klemens Von Metternich, foreign minister of the Austrian Empire during the Napoleonic era and its aftermath, would have no trouble recognizing Google. To him, the world's most popular web-search engine would closely resemble the Napoleonic France that in his youth humiliated Austria and Europe's other powers. Its rivals--Yahoo !, the largest of the traditional web gateways, eBay, the biggest online auction and trading site, and Microsoft, a software empire that owns MSN, a struggling web portal--would look a lot like Russia, Prussia, and Austria. Metternich responded by forging an alliance among those three monarchies to create a "balance of power" against France. Google's enemies, he might say, ought now to do the same thing. Google announced two new conquests on August 7th. It struck a deal with Viacom, an "old" media firm, under which it will syndicate video clips from Viacom brands such as MTV and Nickelodeon to other websites, and integrate advertisements into them. This makes Google the clear leader in the fledgling but promising market for web-video advertising. It also announced a deal with News Corporation, another media giant, under which it will provide all the search and text-advertising technology on News Corporation's websites, including MySpace, an enormously popular social-networking site. These are hard blows for Yahoo! and MSN, which had also been negotiating with News Corporation. Both firms have been losing market share in web search to Google over the past year--Google now has half the market. They have also fallen further behind in their advertising technologies and networks, so that both make less money than Google does from the same number of searches. Sara Rashtchy, an analyst at Piper Jaffray, a securities firm, estimates that for every advertising dollar that Google makes on a search query, Yahoo! makes only 60-70 cents. Last month Yahoo! said that a new advertising algorithm that it had designed to close the gap in profitability will be delayed, and its share price fell by 22% , its biggest-ever one-day drop. MSN is further behind Google than Yahoo! in search, and its parent, Microsoft, faces an even more fundamental threat from the expansionist new power. Many of Google's new ventures beyond web search enable users to do things free of charge through their web browsers that they now do using Microsoft software on their personal computers. Google offers a rudimentary but free online word processor and spreadsheet, for instance. The smaller eBay, on the other hand, might in one sense claim Google as an ally. Google's search results send a lot of traffic to eBay's auction site, and eBay is one of the biggest advertisers on Google's network. But the relationship is imbalanced. An influential recent study from Berkeley's Haas School of Business estimated that about 12% of eBay's revenues come indirectly from Google, whereas Google gets only 3% of its revenues from eBay. Worst of all for eBay, Google is starting to undercut its core business. Sellers are setting up their own websites and buying text advertisements from Google, and buyers are using its search rather than eBay to connect with sellers directly. As a result, "eBay would be wise to strike a deep partnership with Yahoo ! or Microsoft in order to regain a balance of power in the industry," said the study's authors, Julien Decor and Steve Lee, sounding like diplomats at the Congress of Vienna in 1814.
