Developing the defense trilemma of choices between autonomy, stability, and global integration, this article analyzes the strategic tension in military acquisition between undertaking technology partnerships versus off-the-shelf purchases of equipment to meet modernization needs in Latin America. The Brazilian case is examined for its lessons in how partnerships can help countries to achieve strategic goals while promoting industrial capacities. 相似文献

The future Law on Biomedical Research, whose draft bill has been approved by the Council of Ministers and that will soon begin its parliamentary process of approval, will regulate, among other matters, the research with embryos. Likewise, it will make a pronouncement on the so-called therapeutic cloning. This report makes a detailed analysis of different matters that must be borne in mind by the legislator in order to face the process of evaluation and approval of said Law in relation with the aforementioned matters. It makes a special analysis of the legal texts of an international nature to which Spain is unavoidably subjected to, in such a way that the legislative text that will finally be approved is not contrary to the dispositions that are within such. 相似文献

Analyses have been performed of the patenting and invention activity of U.S. scientists and engineers (S&Es) in the academic sector and comparisons have been made with their counterparts in industry. The analyses are based upon survey questions concerning patent applications, grant awards and commercialization outcomes from two 1995 National Science Foundation (NSF) nationally representative workforce surveys. A series of new indicators – patent activity rates, patent activity shares and patent success rates – has been defined and utilized to examine patent activity by employment sector, educational field, demographic variables, status and location of university faculty, technological area, and selected S&E job characteristics. It is recommended that NSF collect data on patenting activity, including commercialization outcomes, in its surveys of the S&E workforce at least every four years. Data should also be collected on university-industry collaboration in patent activity in the U.S., and between S&Es in the U.S. and other countries. 相似文献

The idea of a direct relationship between innovation and progress must be reconsidered. Innovation, in other periods of History merely pursued for the sake of Mankind, eventually turned into an grail for companies willing to see their sales increased. The last decades had witnessed another turn of the screw in that identification: innovation may be used as a weapon to destroy rivals and take over a market, regardless of any considerations of progress. Competition law is not foreign to these new circumstances. The inclusion of innovation as a variable in the context of an exclusionary strategy entails not only an important aggression to free competition, but to social welfare. Due to the novelty of these practices, competition law is still adapting itself to the new scenario. This paper explains the underlying complexity of the study of predatory innovation, establishing the foundations for its proper understanding and subsequent approach of the conclusions to market operators, legislators, judges and to society itself. 相似文献
