In order to increase the use of federally supported research and development to increase U.S. industrial competitiveness, new partnerships are being developed among the research producers, users, and funders. This paper summarizes the evolution of federal technology transfer models with particular attention to university-industry cooperative research centers sponsored by the National Science Foundation. The advantages and potential problems associated with such centers are presented and the implications for technology and innovation are discussed.  相似文献

The application of operations research/management science in the developing country has met with uneven success. Social, cultural, and political factors have constrained direct application of OR technology from industrialized countries to developing countries. Review of OR experience in the United States, especially pitfalls and successes of OR application, does provide significant information which can benefit the application of operations research in the developing country. Successful application of operations research is apt to be highly beneficial if operations researchers in the developing country can effectively deal with the challenges of cultural constraints, an uncertain decision environment, human resource management, and a bounded rationality unique to each developing country.  相似文献

We obtained preferences from 227 college students about the characteristics of their ideal love objects. We factor analyzed these separately for males and females and obtained both common and sex-specific factors. We then examined the relative contributions of a set of structural and family factors to the explanation of variance in each of the characteristics of the ideal love object. Results show that about one-third of the 58 characteristics have significant, though not high, amounts of variance explained by the predictors. The most important predictors were sex, religion, mother's marital happiness, and father's education.Received Ph.D. from New York University, 1963. Major research interest: emotions, love relationships, socialization, sociological theory.Received Ph.D. from City University of New York, 1976. Major research interests: sociological theory, sex roles, sociology of leisure, sociology of health.  相似文献

Several sources are quoted that substantiate the concept that for technology to be effectively used it is necessary to disseminate the technology using a variety of means. The paper then goes on to describe in detail the Forest Service approach to technology dissemination. Some data is shown that substantiates the effectiveness of the Forest Service planned approach to the transferring of research knowledge.  相似文献
