The figures in Table 1 yield some interesting results. The total annual value of food and mineral resources taken from the ocean is $8.3 billion, in contrast to $309 billion from the land. Using the land value as the yardstick, if the annual value of produce from the ocean were in ratio to the area relationship of ocean and land, the ocean potential would be $750 billion; the actual recovery for 1964 was only 1.1 percent of that potential. This very low percentage is the basis for either great optimism for the future development of the ocean (on the basis of unrealized potential), or great pessimism (on the basis of high costs compared with further development of land resources, or present exploitation to near the limit of productivity). 相似文献

In the article "How shall we pay for research and education?" by Paul E. Klopsteg [Science 124, 965 (16 Nov. 1956)], the first sentence under the subhead "Income taxes and individual giving" on page 966 should read: "Notwithstanding the apparent unqualified approval by government of the taxpayer's charitable inclinations, expressed by its permission to him to deduct up to 30 percent of his adjusted gross income for legal charities, he failed in 1954 by about $20 billion to take advantage of this exemption." The printed version "$20 million" was a typographical error. 相似文献

The World Bank, the largest aid-granting agency in the world, has played a substantial but largely unsung role in helping the scientific and technological development of developing countries. Its investments, totaling $15.5 billion in fiscal year 1984, involve choosing appropriate technology and financing local technological development. Since 1980, the Bank has lent $0.5 billion for agricultural research and about $1 billion for scientific and technological education. It contributes to and mobilizes finances for large international research programs in agriculture and the health sciences. It supports research on labor-based construction, low-cost sanitation, renewable energy resources, and control of traffic congestion. It provides training in the technological aspects of development policy. As funds for aid become scarce, the Bank is reexamining its approach to science and technology. 相似文献

The European Union is in danger of losing ground in the global research competition unless its member nations devote more resources to science, restructure the E.U.'s flagship research program, and develop a Europe-wide science strategy, an expert panel says. Framework 5--which provides $17 billion over 5 years for multinational research efforts and scientific networking--should be made more flexible to respond to hot new research fields, the report suggests, and its complex grant-application procedures should be made "much simpler and easier to understand." 相似文献

Areawide suppression of European corn borer with Bt maize reaps savings to non-Bt maize growers 总被引:1,自引:0,他引:1
Hutchison WD Burkness EC Mitchell PD Moon RD Leslie TW Fleischer SJ Abrahamson M Hamilton KL Steffey KL Gray ME Hellmich RL Kaster LV Hunt TE Wright RJ Pecinovsky K Rabaey TL Flood BR Raun ES 《Science (New York, N.Y.)》2010,330(6001):222-225
Transgenic maize engineered to express insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) has become widely adopted in U.S. agriculture. In 2009, Bt maize was planted on more than 22.2 million hectares, constituting 63% of the U.S. crop. Using statistical analysis of per capita growth rate estimates, we found that areawide suppression of the primary pest Ostrinia nubilalis (European corn borer) is associated with Bt maize use. Cumulative benefits over 14 years are an estimated $3.2 billion for maize growers in Illinois, Minnesota, and Wisconsin, with more than $2.4 billion of this total accruing to non-Bt maize growers. Comparable estimates for Iowa and Nebraska are $3.6 billion in total, with $1.9 billion for non-Bt maize growers. These results affirm theoretical predictions of pest population suppression and highlight economic incentives for growers to maintain non-Bt maize refugia for sustainable insect resistance management. 相似文献

Academic scientists are hoping that two new reports calling for increased funding of research and education and an improved climate for commercializing new technology will finally boost an R&D budget that has been stagnant since 1996. One report argues for a variety of measures to reduce the country's reliance on such low-tech commodities as agriculture and precious metals and stimulate innovation. The second report, based on an innovation summit held in February, recommends spending $1.4 billion over 5 years on research, facilities, and education. 相似文献

Disaffection with the European Union's (E.U.'s) flagship research effort has found a sympathetic ear in the program's upper echelons. Last week, the E.U.'s top two research officials said they are pushing for big changes in the successor to Europe's 5-year, $17 billion Framework 5, including stronger efforts to coordinate research across the continent and to support innovative projects. 相似文献

Last week federal Finance Minister Paul Martin announced a $268 million outlay for future equipment awards provided by the Canada Foundation for Innovation (CFI), a $1.3 billion entity created in 1997 to rejuvenate labs in universities and research hospitals. The money is the first direct federal outlay for overhead costs, which up to now have been met by a combination of provincial operating grants to universities and federal transfer payments for postsecondary education. School administrators say it meets a desperate need. 相似文献

Congress last week gave both NASA and the National Science Foundation (NSF) significant hikes for 2001: NSF got $4.42 billion, a $522 million boost over this year that nearly matched NSF's 17% request, and NASA received $14.3 billion, nearly twice the White House's request for a 3% boost-but with hundreds of millions of dollars in earmarks added on. 相似文献

Whereas growth accountants use standard monetary measures of return on investment to estimate information technology's impact on productivity, those who study the country's $45 billion annual investment in biomedicine tend to talk instead about "the social rate of return." In health, they argue, the coin of the realm is having a longer, more comfortable life. Two reports released last May conclude that this return is huge-in some cases, more than $20 for every dollar invested. 相似文献

During the past several years there have been significant scientific and technological advances related to the tokamak magnetic confinement scheme. These are summarized in the context of a recent tokamak reactor design study which emphasizes reduced size, higher power density, and enhanced plant reliability and maintainability relative to earlier tokamak reactor design studies. The direct plant cost of the proposed reactor is estimated to be in the range $1000 to $1500 per electrical kilowatt. A three-phase strategy for demonstrating tokamak fusion power generation at a committed site is outlined. It is estimated that implementation of the three-phase program would require about 20 years and a total escalated expenditure $10 billion to $15 billion. The tokamak power plant described here is not viewed as definitive but rather as a point of departure in the development of a plan to demonstrate tokamak power generation. 相似文献

British scientists are celebrating a $1.7 billion windfall, announced last week by the U.K. government, to shore up deteriorating facilities and raise stipends for Ph.D. students. The 2-year spending boost is intended to keep the pool of British science well stocked, both by attracting more talented students into the field and stemming the flow of scientists out of the country. But the benefits are not spread evenly across the research spectrum. 相似文献

We estimate that to achieve the World Health Organization's tuberculosis control targets, the 22 high-burden countries (HBCs) that collectively account for approximately 80% of the world's tuberculosis cases require about $1 billion per year during the period 2001 to 2005. A further $0.2 billion per year is needed for low and lower-middle income countries outside the 22 HBCs. There is a resource gap of up to around $300 million per year. Substantial progress in tuberculosis control could be achieved with increased investment that is large in the context of existing spending, but small in the wider context of global health expenditure. 相似文献
