This paper describes some of the spinoff benefits that can result from R&D projects, and categorizes them in terms of the dimensions of market and technical newness. These dimensions are discussed with reference to two types of spinoffs: 1) alternative market applications, when the results of an R&D project are subsequently applied to a market or use that differs from the originally intended application, and 2) second-generation technologies, when the technology that was the subject of an R&D project is significantly altered or enhanced in unanticipated ways through subsequent R&D. Examples from the Department of Energy's Energy-Related Inventions Program are integrated into the results of literature review to illustrate key concepts, including core technologies, degrees of market and technology newness, technology robustness, and the nature of connections linking spinoffs to prior R&D investments. The paper concludes by discussing spinoffs as a managerial strategy.  相似文献

This article examines the case for a participatory policy analysis. An idea advanced mainly by democratic and postpositivist theorists is increasingly becoming a practical concern. Criticizing conventional conceptions of science and expertise, theorists advocating participatory democracy argue that the conventional model of professionalism based on a practitioner-client hierarchy must give way to a more collaborative method of inquiry. While such arguments have largely remained in the domain of utopian speculation, recent experiences with a number of wicked policy problems have begun to suggest the viability, if not the necessity, of participatory research methods. Through two case illustrations of a wicked problem, the so-called Nimby Syndrome, the essay seek to demonstrate that collaborative citizen-expert inquiry may well hold the key to solving a specific category of contemporary policy problems. The article concludes with some observations on the possibilities of bringing participatory research more fully into mainstream policy science.  相似文献

The “tragedy of the commons” is the familiar problem that open access to a common property resource leads to overexploitation and to zero profits. A commons model is applied to an example of state sponsored private violence, the practice of privateering or licensed piracy. It is predicted that the presence of uncertainty about the value of the prey will reduce the amount of exploitation effort, and that industry profits may be positive due to both uncertainty and heterogeneous exploiters. Using data from England's wars with France and Spain between 1625 and 1630, the model suggests that the commons, represented by enemy merchant shipping, was not overexploited and that privateering profits were positive. The dynamic paths of privateering effort, ships seized, and individual firm profits were, however, consistent with the normal expectation that commons exploitation will peak and fall, as competition drives down returns through entry. “England was never richer than when at war with Spain.” Sir Edward Coke   相似文献

Data from the 1987 National Health and Fertility Survey were used to explore trends and differentials in unwanted fertility in Mexico. Women were classified in three educational categories: illiterate or incomplete primary, complete primary or some secondary, and complete secondary or more. The four urbanization categories were: under 2500; 2500 to 19,999; 20,000 and more; and metropolitan areas. The place of primary socialization was the place of residence until age 12. Two categories of employment of household head were included, agricultural or nonagricultural. The categories for mother's employment considered employment until the union and employment between the time of union and the birth of the first child. The proportion of births that were unwanted was estimated by calculating the total fertility rate for the year before the survey and comparing it to desired family size. The "total desired family size" was 2.4 for the entire sample. In other words, nearly 37% of the total fertility rate was undesired. The greatest differentials in percentages of undesired fertility were found in educational categories. 40.7% of the total fertility rate in the least educated groups vs. 13.6% in the most educated groups was undesired. Differentials in the other categories ranged from 1.9 for a history of employment before the birth of the first child to 8.8 for agricultural or nonagricultural employment of the household head. When effects of education were controlled, the percentage of undesired fertility declined as educational level increased for all rural or urban residence categories, places of socialization, and employment groups except women who worked before the first child was born. Women with more education, urban residence, and with histories of employment had the lowest levels of undesired fertility.  相似文献

The medical capabilities derived from modern reproductive technology, such as in vitro fertilization and cryopreservation, have enabled physicians and scientists to intervene in the procreative process in innumerable ways. However, this intervention in the natural reproductive process raises both moral and legal concerns. In this Article, Professor Schiff explores some of the conflicts that may result when an individual or couple elects to cryopreserve gametes or embryos and subsequently, one or both of the contributors dies, or when gametes are harvested from a dead body. This Article will specifically address the moral and legal responses to circumstances where the decedent has either clearly expressed opposition to posthumous use of the reproductive material or else the decedent's intent regarding posthumous use of the material is ambiguous. By discussing philosophical and moral positions relating to personhood and the body and analyzing legal issues such as reproductive choice and organ donation, Professor Schiff creates the necessary format to examine and recommend the proper legal treatment of this controversial aspect of posthumous procreation.  相似文献

Lawyers and judges faced with a contemporary constitutional issue must try to construct a coherent, principled, and persuasive interpretation of the text of particular clauses, the structure of the Constitution as a whole, and our history under the Constitution--an interpretation that both unifies these distinct sources, so far as this is possible, and directs future adjudication. They must seek, that is, constitutional integrity.  相似文献
