Universities have long been involved in knowledge transfer activities. Yet the last 30 years have seen major changes in the governance of university–industry interactions. Knowledge transfer has become a strategic issue: as a source of funding for university research and (rightly or wrongly) as a policy tool for economic development. Universities vary enormously in the extent to which they promote and succeed in commercializing academic research. The identification of clear-cut models of governance for university–industry interactions and knowledge transfer processes is not straightforward. The purpose of this article is to critically discuss university knowledge transfer models and review the recent developments in the literature on research collaborations, intellectual property rights and spin-offs, those forms of knowledge transfer that are more formalized and have been institutionalized in recent years. The article also addresses the role played by university knowledge transfer organizations in promoting commercialization of research results.

Abstract

In the Chinese Cultural Revolution – the epicenter of the last great political sequence at worldwide level in the 1960s and 1970s – the flashing of unprecedented possibilities of post‐party politics was entangled with the epochal closure of a network of political culture. The Cultural Revolution proves to be extremely refractory to historical investigation because it undoes the established conceptual bridges between history and politics, bridges that all other social sciences crossed for studying politics. Therefore, new theoretical perspectives and new protocols of investigation are required, and not only for those events, but in the last analysis for the study of all political situations. The author discusses three main points for finding a new perspective. First, a basic distinction should be stressed between the intermittent nature of politics – one of the rarest modes of subjectivity, which exist only in singular intellectually inventive sequences – and the structural invariance of the state, despite the incessant historical mutations of its particular forms. Moreover, the relationships between the present state of depoliticization and the previous political situations deserve close analysis. The hypothesis is that the concrete form of the state in a given moment is the hollow imprint of the last great political sequence, or that it is shaped by a reactive de‐politicization. Finally, the declarations and the related behaviors of the actors during the events are the major analytical elements in the study of politics. However, the Cultural Revolution was marked to an unprecedented degree by increasing dissonances and, finally, irremediable ruptures between the processes created by the subjective declarations and the same network of political culture within which they were formulated.  相似文献

One of the most significant results of the qualitative literature on national systems of innovation (NSIs) is that different systemic arrangements (i.e. configurations of actors and institutions) can deliver similar levels of innovative performance. Using factor analysis on a novel dataset of 29 quantitative indicators of innovative activities we provide an empirical characterization of the structure of European NSIs over the last ten years. Our results cast doubt on the empirical significance of the “equifinality” of heterogeneous systemic arrangements in the context of NSI. Innovation systems show inherent complexity, which leads to a high level of complementarity among their constituent components and configuration. This result implies that successful innovation policies should be systemic, leaving little flexibility in policy design and scope.  相似文献

This paper examines the relationship between the economic growth of European regions and their knowledge and human capital endowments. The share of adult population with tertiary education and the intensity of R&D expenditures in value-added emerge as the most effective factors enhancing the growth of GDP per capita recorded, during 1995–2002, by the regions belonging to twelve countries of the former EU15. However, while the educational variable is effective for the whole regional set, the impact of R&D is significant only for the regions that are above a given threshold of per capita GDP. Moreover, remarkable disparities arise among the regions of different countries. In particular, only within North European countries there is a significant relationship between regional growth and the intensity of R&D and higher education. The policy implications of both findings are discussed.  相似文献

Students' opinions about the opportunities and the implications of VR in instruction were investigated by administering a questionnaire to humanities and engineering undergraduates. The questionnaire invited participants to rate a series of statements concerning motivation and emotion, skills, cognitive styles, benefits and learning outcomes associated with the use of VR in education. The representation which emerged was internally consistent and articulated into specific dimensions. It was not affected by gender, by the previous use of VR software, or by the knowledge of the main topics concerning the introduction of IT in instruction. Also the direct participation in a training session based on an immersive VR experience did not influence such a representation, which was partially modulated by the kind of course attended by students.  相似文献

This paper presents a stabilizing control for two-dimensional stochastic differential equations. The stability concept in this study is the stability in probability. To ensure such a stability, the control is designed based on the sliding mode technique, and applied to account stochastic systems. This finding has a practical implication—the proposed control can be used to stabilize a real-time automotive electronic throttle valve. The proposed approach is verified by data collected from experiments.  相似文献

Abstract

This article discusses the scientific research work on environmental education presented during the last decade in three Brazilian conferences: the meetings of the National Association of Graduate Research on Education (Associação Nacional de Pós-Graduação e Pesquisa em Educação, ANPEd), the National Association of Graduate Research on Environment and Society (Associação Nacional de Pós-Graduação e Pesquisa em Ambiente e Sociedade, ANPPAS), and the Environmental Education Research Meetings (Encontros de Pesquisa em Educação Ambiental, EPEA). It analyzes the authors, institutions, and regions whence the studies came from, as well as their main research subjects. Our findings indicate the prevalence of women in all academic degree segments; of PhD holders and candidates; of professors in public higher education institutions located in the Brazilian Southwest and South regions; and of environmental education in formal teaching as the main subject in all three conferences. Based on these results, we discuss how this body of research relates to the development of Brazilian academic and educational policies, and indicate some of the challenges involved in building a research tradition in this field, in close dialogue with the arduous political and pedagogical path of environmental education in Brazilian schools.  相似文献

The aim of the study was to evaluate the dorsal and lumbar spine of expert and recreational tennis players before (pre) and after (post) two different training sessions. The sample consisted of 17 male tennis players, nine expert and eight recreational males (age 21.2 ± 1.6 years). We assessed the back surface by rasterstereography pre and post two different training sessions both lasting 1.5 h: a standard training and a specific over-shoulder shots training session, respectively. Lordotic and kyphotic angle, length, imbalance, inclination for trunk, pelvic torsion, left and right lateral deviation and surface rotation were measured. Tennis expertise (expert versus recreational) significantly affected the surface rotation and right lateral deviation (P < 0.05). Trunk length was affected by intervention (pre versus post) (P < 0.05). Left lateral deviation differed both for type of session (session 1 versus session 2) and intervention (P < 0.001, P < 0.05). Expert tennis players had higher values on surface rotation and right lateral deviation, around or just above physiological values (0–5° and 0–5 mm, respectively). Type of session significantly affected left lateral deviation, indicating that over-shoulder shots lead to a higher stress for the spine; the workload produced by both single sessions led to a shortening effect on trunk length. A single training session can induce acute modifications in some parameters of dorsal and lumbar spine of players.  相似文献

Although exercise promotes beneficial effects in diabetic patients, some studies have questioned the degree of their importance in terms of the increase in total energy expenditure. In these studies, the decrease of physical activity levels (PAL) was referred as “compensatory effect of exercise”. However, our aim was to investigate whether aerobic exercise has compensatory effects on PAL in type 2 diabetes patients. Eight volunteers (51.1 ± 8.2 years) were enrolled in a supervised exercise programme for 8 weeks (3 d · wk?1, 50–60% of VO2 peak for 30–60 min). PAL was measured using tri-axial accelerometers in the 1st, 8th and 12th weeks. Biochemical tests, cardiorespiratory fitness, anthropometric assessment and body composition were measured in the 2nd and 11th weeks. Statistical analysis was performed using non-parametric tests (Friedman and Wilcoxon, P < 0.05). We found no significant differences in PAL between intervention periods, and participants spent the majority of their awake time in sedentary activities. However, the exercise programme generated a significant 14.8% increase in VO2 peak and a 15% reduction in fructosamine. The exercise programme had no compensatory effects on PAL in type 2 diabetes patients, but improved their cardiorespiratory fitness and glycaemic control.  相似文献
