Mary T. Tyszkiewicz 《The Journal of Technology Transfer》1991,16(4):43-49
Research collaboration between government, universities, and industry, as well as among member nations, has been a prominent
strategy in the European Community's science and technology policy through the 1980s and into the 1990s. In the perspective
of the Single European Act and 1992 Plan, this paper outlines the lessons from European research collaboration for the United
States. The structure of the European Community's cooperative R&D programs are reviewed and support for the development of
advanced materials is highlighted. In the context of the benefits from the European Community's programs, five policy implications
can be discerned for the US: establishment of forums for industry and government to dialogue about research priorities, institution
of programs to promote strategic industrial R&D through cost-sharing, encouragement of small and medium-size firms to cooperate
in R&D in high-technology sectors, monitoring of European research and development programs, and development of reciprocity
policies for foreign-company membership in national collaborative R&D programs.
Mary T. Tyszkiewicz is senior research associate in the Technology and Information Policy Program at Syracuse University. She has an MS in inorganic
chemistry from Iowa State University and MSc. in Science, Technology, and Industrialization from the Science Policy Research
Unit at University of Sussex in Brighton, England. 相似文献

Based on reports from 143 male college students, the relationship between a dating partner's perceived level of competitiveness and combativeness (one's own and one's partner's) is examined. Competitiveness is seen as a direct measures of efforts to exert control. Findings show that even high levels of pleasant competitive behaviors are unrelated to combativeness. However, as scores on a measure of unpleasant competitive behaviors increase, so do scores on a measure of combativeness. Recommendations are offered to educators and counselors regarding the nexus between competitiveness and courtship problems. 相似文献
