阅读材料,回答下面的题目。The Diminishing Scientific Leadership of the U, S.With the rapid globalization of science itself ( more than 40 percent of scientific Ph.D. students trained in the United States are now foreign nationals, roughly half of whom return to their countries of origin ) , the once undisputed U.S.scientific lead, whether relevant to product lead or not, is diminishing. The competition of foreign students for positions in U.S.graduate schools has also contributed to making scientific training relatively unattractive to U.S.students, because the rapidly increasing supply of students has diminished the relative rewards of this career path. For the best and brightest from low-income countries, a position as a research assistant in the United States is attractive, whereas the best and brightest U.S.students might now see better options in other fields. Science and engineering careers, to the extent that they are opening up to foreign competition ( whether imported or available through better communication ) , also seem to be becoming relatively less attractive to U.S. students. With respect to the role of universities in the innovation process the speculative boom of the 1990s( which, among other things, made it possible to convert scientific findings into cash rather quickly ) was largely unexpected.The boom brought universities and their faculties into much closer contact with private markets as they tried to gain as much of the economic dividends from their discoveries as possible. For a while,the path between discoveries in basic science and new flows of hard cash was considerably shortened. But during the next few decades, this path will likely revert toward its more traditional length and reestablish in a healthy way, the more traditional ( and more independent ) relationship between the basic research done at universities and those entities that translate ideas into products and services.In the intervening years, another new force also greatly facilitated globalization: the rapid growth of the Internet and cheap wide-bandwidth international communication. Today, complex design activities can take place in locations quite removed from manufacturing, other business functions and the consumer. Indeed, there is now ample opportunity for real-time communication between business functions that are quite independent of their specific locations. For example, software are development, with all its changes and complications, can to a considerable extent be done overseas for a U.S.customer.Foreign call centers can respond instantly to questions from thousands of miles away.The result is that low-wage workers in the Far East and in some other countries are coming into even more direct competition with a much wider spectrum of U.S. labor: unskilled in the case of call centers; more highly skilled in the case of programmers.
阅读材料,回答下面的题目。The New Technology ApplicationOn a more mundane level, third-generation mobile telephones, despite all the delays and the billions squandered on 3G licenses by telecom firms, are still expected to offer consumers high-speed, always on mobile internet access, complete with video, in the next few years.Rapidly proliferating "WiFi" networks already offer wireless access on a local basis. Tiny tracking chips called radio-frequency identification devices are being used as pet passports.Soon they will be small, powerful and cheap enough to be implanted into everything form humans to milkcartons recording and transmitting real-time medical data, or serving as a form of inventory control.Sensors of every kind, including video cameras, should also become much smaller and cheaper.Forrester Research, a technology consultancy, predicts that 14 billion such devices will be connected to the internet by 2005.How rapidly such new technology is introduced will depend on a number of factors the state of the economy, the supply of investment capital and the appetite of consumers for new products or services ! Fortunes will be made and lost many times over.But whatever happens, the power of computing and communications look set to continue to grow, and its price to fall, at a steady rate for the next few decades.That will make it possible, at least in rich countries, to record most human interactions, wherever and whenever they take place, and to store and analyze this ocean of data at low cost.For the sake of argument, this survey will assume that we are heading towards a networked society of ubiquitous, mobile Communication capable of constant monitoring.Whether this arrives in 20,30 or 40 years does not really matter.The point is that the destination seems not merely possible, but probable, so it is not toosoon to ask: What do we want this technology to do?The internet has already thrown up a host of legal and political conundrums, but, these are only a small foretaste of the dilemmas about privacy, security, intellectual property and the nature of government itself that will have to be faced over the coming decades.The debate has already begun. This survey will outline some of main issues, and speculate on the way they are likely to go. Radio-frequency identification devices__________.

Publicity then is part of public relations when it is initiated by the firm, usually in the51of press releases or press conferences.
