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

Postmodern inquiry into the discursive construction of identity has the potential to make a distinctive, democratizing contribution to public policy analysis. More so than conventional approaches, a postmodern policy analysis offers the opportunity to interrogate assumptions about identity embedded in the analysis and making of public policy, thereby enabling us to rethink and resist questionable distinctions that privilege some identities at the expense of others. Public policy analysis can benefit from postmodernism's emphasis on how discourse constructs identity. A review of postmodernism and postmodern approaches to interrogating identity is followed by an exercise in postmodern policy analysis. Social welfare policy in contemporary postindustrial America is shown to participate in the construction and maintenance of identity in ways that affect not just the allocation of public benefits, but also economic opportunities outside of the state. Mired in old, invidious distinctions (e.g., independent/dependent, contract/charity, family/promiscuity), welfare policy discourse today helps to recreate the problems of yesterday, particularly as a critical factor in reproducing women's poverty.  相似文献

The welfare state is often accused of being counterproductive: as the scope of public responsibility expands, private morality (especially altruism and benevolence) atrophies. This essay surveys psychological findings for evidence, which turns out to be broadly consistent with either of two models of moral development, each bearing distinct policy implications. The model of morally keeping in practice that is implicit in the term moral atrophy suggests the need for frequent opportunities to exercise moral skills, which would seem inconsistent with the welfare state. Alternatively, the model of moral character-building favoured by both philosophers and ordinary discourse would require only occasional reminders of one's moral principles. On this model, benevolence could usefully supplement the welfare state.  相似文献
