This paper addresses research in the life sciences, responsible for significant national expenditures for scientific investigations funded by both the federal government and industry. Our investigation examines faculty members' involvement with industry in entrepreneurial ways that is, involved in translating their research into potentially marketable knowledge or products. First, this study examines whether there are differences in entrepreneurial behaviour between clinical and non-clinical faculty in the life sciences with industry relationships, and, second, to discover any linkage between entrepreneurship and secrecy or productivity in different ways for clinical and non-clinical faculty. The study is based on survey responses of a national sample of 4,000 clinical and non-clinical life sciences faculty in 49 U.S. research universities. The results show non-clinical faculty as more involved at the back end. The more entrepreneurial end of commercialization while clinical faculty are involved at the back end. The more entrepreneurial faculty (non-clinical) are more likely to be secretive about their research. Clinical faculty are less likely to have been denied access to research results or products. Entrepreneurial faculty are not less productive in their faculty roles. This investigation is preliminary in that it addresses one large area of academic research but excludes fields with longer historical relationships with industry.  相似文献

Despite decades of critical reframings, policy and practice on prisoner (re)entry often remains situated within a framework of individual responsibility that fails to acknowledge the structural drivers of criminalization. Attending to individual symptoms rather than root social, political and economic causes, such approaches may ultimately reinforce the inequalities and injustices that fuel imprisonment. This article presents a case study of an alternative approach. It examines A New Way of Life Reentry Project, a nonprofit organization in South Los Angeles, California, that offers housing and support to women coming home from prison through a critical and holistic framework—one that attends simultaneously to the physical, mental and social contexts that shape lived experiences before, during and after prison. Drawing from 7 years of observation and participation, supplemented by ten in-depth interviews, I argue that a critical, holistic approach can have a significant positive impact for people returning home from prison.  相似文献

Biochar currently attracts technological and market optimism, promising multiple wins – for climate change, food security, bioenergy and health – not least for African farmers. This paper examines the political-economic and discursive processes constructing biochar as a novel green commodity, creating new alliances amongst scientists, businesses, venture capital firms and non-governmental organisations. Carbon market logics are not only threatening large-scale land grabs for biochar feedstocks but also other forms of resource, labour and ecological appropriation through driving research and development and shaping small-scale pilot projects. In these, soil carbon is ‘chopped out’ of its ecosystem and social contexts and revalued as exchangeable pieces of carbon nature. Farmers are hailed as green actors and market winners, provided they discipline their practices according to these new technical and market logics. These discourses contrast strongly with the farmers' existing conceptual and practical repertoires; a case study from Liberia illustrates how farmers already manipulate soil carbon in creating locally valued anthropogenic dark earths, but within diverse farming repertoires, ontologies of human–nature interrelationship and historical and political ecologies.  相似文献

In an effort to take positive steps toward coping with problems for families and children created by high levels of separation and divorce, ever increasing civil caseloads and the exposure of children to interparental conflict, court‐affiliated educational programs have emerged in the United States for parents separating from their spouse or partner or going through a divorce. This article will provide an overview of the creation of such programs and their development, which includes a discussion regarding the numerous states currently mandating parents to attend. It will summarize some of the research which has been conducted as to the efficacy of the programs and will provide the results of our nationwide research for each state's parent education status. There is a discussion of domestic violence issues and sensitivities in the context of parent education programs and possible future directions for mandatory parent education.  相似文献
