The effectiveness of university knowledge spillovers: Performance differences between university spinoffs and corporate spinoffs 总被引:2,自引:0,他引:2
While much prior research has focused upon how the Technology Transfer Offices (TTOs) and other contextual characteristics shape the level of university spinoffs (USO), there is little research on entrepreneurial potential among individual academics, and to the best of our knowledge, no comparative studies with other types of spinoffs exist to date. In this paper we focus on an important but neglected aspect of knowledge transfer from academic research involving the indirect flow to entrepreneurship by individuals with a university education background who become involved in new venture creation by means of corporate spinoffs (CSO) after gaining industrial experience, rather than leaving university employment to found a new venture as an academic spinoff. We argue that the commercial knowledge gained by industry experience is potentially more valuable for entrepreneurial performance compared to the academic knowledge gained by additional research experience at a university. This leads us to posit that the average performance of CSOs will be higher than comparable USOs, but the gains from founder‘s prior experiences will be relatively higher among USOs whose founders lack the corporate context. We investigate these propositions in a comparative study tracking the complete population of USOs and CSOs among the Swedish knowledge-intensive sectors between 1994 and 2002. 相似文献

Within the academic field of futures in education there has been concern that pupils’ negative and pessimistic future scenarios could be deleterious to their minds. Eckersley (Futures 31:73–90, 1999) argues that pessimism among young people can produce cynicism, mistrust, anger, apathy and an approach to life based on instant gratification. This article suggests that we need to discuss negative and pessimistic future visions in a more profound and complex way since these contain both hope and hopelessness. A pessimistic view of the future does not have to be negative in itself: it can also illustrate a critical awareness of contemporary social order. This article therefore aims to explore hope and hopelessness in young people’s dystopias about the future. Adopting dystopias may open up possibilities, whereas adopting disutopias will only lead one to believe that there are no alternatives to the current dominant model of global capitalism. Even a dystopia that predicts the end of the world as we know it might be the beginning of a world that we have not seen yet. 相似文献

It has been suggested that the psychological stress associated with competitive sports events may help to explain the increased susceptibility to respiratory infections due to reductions in secretory immunity. In the current study, we investigated the influence of competitive exercise and psychological stress on secretory immunoglobulin A (s-IgA). Salivary s-IgA and heart rate were measured in 62 healthy young recreationally active men at rest and, in a between-subjects design, following one of four 8-min tasks: mental arithmetic, cycling at workloads of 60 to 180 W (mean = 146 W), mental arithmetic while cycling, or competitive cycling. Mental arithmetic was associated with significant increases in s-IgA concentration (mean = 49 microg.min(-1)) and s-IgA secretion rate (mean = 25 microg.ml(-1)) compared with rest, while mental arithmetic combined with exercise was associated with a significant increase in s-IgA concentration only (mean = 124 microg.min(-1)). In contrast, competitive exercise and exercise alone did not influence s-IgA concentration or secretion rate. Heart rate increased modestly to mental arithmetic (mean = 7 beats.min(-1)) and substantially, and similarly, to the three exercise tasks (mean = 56(62 beats.min(-1)). The hypothesis that the psychological stress of competitive exercise contributes to increased susceptibility to infection via reductions in s-IgA requires further investigation. 相似文献

An easy method is introduced allowing fast polydimethylsiloxane (PDMS) replication of nanofluidic lab-on-chip devices using accurately fabricated molds featuring cross-sections down to 60 nm. A high quality master is obtained through proton beam writing and UV lithography. This master can be used more than 200 times to replicate nanofluidic devices capable of handling single DNA molecules. This method allows to fabricate nanofluidic devices through simple PDMS casting. The extensions of YOYO-1 stained bacteriophage T4 and λ−DNA inside these nanochannels have been investigated using fluorescence microscopy and follow the scaling prediction of a large, locally coiled polymer chain confined in nanochannels. 相似文献

Manufacturing technologies for making advanced micro systems have been developing in a rapid pace recently. Research progress towards nanosized structures and devices opens up a whole new horizon for miniaturized system integration. Advances in this field will have an enormous societal impact and economic benefit in areas such as information technology, energy, healthcare, and many more. There has been an enormous scientific and industrial interest in nanosized advanced technologies. The theories, tools and practices for the design, manufacturing and test of these systems are emerging. The aim of this special section is to capture some of the latest developments in integration technologies for the micro/nanosystems, with the following topics: Molecular and crystal assembly inside the carbon nanotube: encapsulation and manufacturing approachesElectroplating for high aspect ratio vias in PCB manufacturing: enhancement capabilities of acoustic streaming Local synthesis of carbon nanotubes for direct integra tion in Si microsystemsdesign considerations Waferlevel SLID bonding for MEMS encapsulation Effect of substrates and underlayer on CNT synthesis by plasma enhanced CVD These papers will briefly highlight important advance ments in manufacturing technologies of the micro/nano systems, and outline the blueprint of upcoming information technology revolution from the manufacturing point of view. 相似文献

Although large international studies have defined Norway as one of the most secular countries in the world, Christian folk high schools in Norway have experienced record high attendance. This paper presents case studies of the religious education (RE) and practices of two Christian folk high schools in Norway. A survey shows that students at these schools can be considered representative of the confessional backgrounds and stated values of their cohort of Norwegian youth. The studied institutions have the declared goal of offering RE, of which an on-campus worship service is a central element. A large portion of the student body attends these services. Using a reconstruction of Etienne Wenger’s theory of communities of practice, the author analyses student participation in the school worship service, specifically in the act of candle lighting. Observations and student interviews indicate that the service can be described as a reflective practice representing a dialogic form of religion. This article contributes an analysis of the distinctive form of RE offered by Christian folk high schools in Norway. In a broader sense, it contributes to the understanding of secular youth and their relation to religious practice. 相似文献

The paper reflects on the prospects for higher education reform in a country - South Africa - lodged within a sub-continent not noted for successful reform. The argument is that much of the policy debate is conducted in a way that dichotomises the issues: control versus autonomy; freedom versus regulation; state versus civil society. This dichotomous construal is unable to deal adequately with recent work on the changing forms of the state and changing state-higher education relations. The paper develops a distinction between administrative and political forms of control; and broadens the state control-state supervision distinction from one based solely on models to one based on the specific quality of inter-organisational coordination, connectivity and regulation. The paper concludes by spelling out what such a connective conception of organisation and regulation could mean for South African higher education. 相似文献
