Given the importance in recent years of the phenomenon of academic entrepreneurship in European universities, knowledge about
determinants and performance of this technology transfer mechanism may have important managerial and policy implications.
Applying the resource-based view at universities, we have tested the influence of five bundles of resources and capabilities
on spin-off activity rates as well as on the performance of new spin-offs in a sample of seven European universities. These
five bundles are: technology transfer policies and strategies; human capital; stock of technology; resources and capabilities
of technology transfer offices; and support measures for academic entrepreneurship. Our results show that excellence of human
capital and the presence of university-based financial support measures are strongly associated with both spin-off activity
and performance. Another interesting finding is related to the availability of university-based non-economic support measures
(training, counselling, etc.), which have no influence on spin-off activity but are significantly associated with performance
of new spin-offs. We also discuss some interesting relationships between explanatory variables. 相似文献

We characterize the investor’s optimal portfolio allocation subject to a budget constraint and a probabilistic VaR constraint
in complete markets environments with a finite number of states. The set of feasible portfolios might no longer be connected
or convex, while the number of local optima increases exponentially with the number of states, implying computational complexity.
The optimal constrained portfolio allocation may therefore not be monotonic in the state–price density. We propose a type
of financial innovation, which splits states of nature, that is shown to weakly enhance welfare, restore monotonicity of the
optimal portfolio allocation in the state-price density, and reduce computational complexity.

Building on research by Akehurst et al. (Serv Ind J 32:2489–2505, 2012), this study analysed internal and external factors in women entrepreneurship and linked these factors to the barriers that women face when starting businesses. To do so, two contrasting statistical techniques were used: PLS and QCA. After analysing results from each of these techniques, we observed that family duties and difficulties in obtaining financing (both internal and external) were the main factors related to barriers faced by women entrepreneurs. 相似文献

In this study we integrate insights from ‘top‐down’ and ‘bottom‐up’ traditions in organizational change research to understand employees’ varying dispositions to support change. We distinguish between change initiation and change execution roles and identify four possible role configurations in which top managers (TMs) and middle managers (MMs) can feature in change. We contend that both TMs and MMs can play change initiation and/or change execution roles, TMs and MMs have different strengths and limitations for taking on different change roles, and their relative strengths and limitations are compounded or attenuated based on the specific configuration of change roles. We subsequently hypothesize employee support for change in relation to different TM‐MM change role configurations. Our findings show that change initiated by TMs does not engender above‐average level of employee support. However, change initiated by MMs engenders above‐average level of employee support, and even more so, if TMs handle the change execution. 相似文献

Work,employment and engagement conditions in a female‐dominated public service occupation after restructuring/outsourcing

Most research on the phenomenon of public service restructuring/outsourcing focuses on lower skilled work in peripheral activities and typically provides an overview of effects on work, employment and employment relations. Through an in‐depth case study of probation, the intention of this article is to explore professional worker experiences of the restructuring/outsourcing of a core public service activity where the workforce is female dominated. The article highlights three dimensions of job quality that all suffered deterioration—work, employment and engagement. The case of probation adds to evidence demonstrating that employees experience adverse effects even though transfer regulations and union agreements supposedly protect workers. Probation also stands as an exemplar of impoverishment processes in a female‐dominated occupation which reinforces the view that public services can no longer be relied upon to provide high‐quality jobs for highly qualified women. 相似文献

The aim of this study is to investigate the elements of organizational career management (OCM) that can lead to strong organizational performance. The growing unpredictability of careers requires a different organizational approach of careers. Yet, new career models all focus on the individual as the central actor, leaving the role of the organization rather underdeveloped. Based on a combined perspective integrating insights from the literature on careers, high performance work systems, and idiosyncratic deals (I‐deals), we address four dimensions of OCM: supportive and developmental practices, development I‐deals, individual responsibility, and consensus. We study their relationships with company performance, thereby including the firm's human capital composition. Surveys were administered to the HR directors of 293 organizations. We apply a relatively new method, fsQCA (fuzzy‐set qualitative comparative analysis), and complement this with more conventional structural equation modeling (SEM). The SEM analyses suggest that only supportive and developmental practices are positively associated with high performance. However, based on the fsQCA, three configurations are identified in which OCM is associated with high performance. The most prevalent configuration combined supportive and developmental practices with I‐deals and individual responsibility for career management. We conclude with a discussion of the implications of our findings, and address the utility of adopting a configurational approach in career research. © 2016 Wiley Periodicals, Inc. 相似文献

An evolutionary approach to the delimitation of labour market areas: an empirical application for Chile. Spatial Economic Analysis. Labour market areas (LMAs) are argued to represent a more appropriate policy framework than administrative units for the analysis of spatial labour market activity. This article develops LMAs for Chile by applying an evolutionary computation approach. This innovative approach defines LMAs through an optimization process by maximization of internal cohesion, subject to restrictions of minimum levels of self-containment and population. To evaluate the appropriateness of the LMAs, comparative analyses are performed between alternative delimitations based on different parameter configurations of the proposed method versus administrative boundaries and the most widely used method for official LMA delimitation, the travel-to-work areas method. 相似文献

Networks are recognized as a central component of the entrepreneurial process, in particular with regard to opportunity identification and exploitation. In this study, we specifically analyze the role of mentors who are in business as opportunity brokers and enablers among university students with entrepreneurial intentions. Our investigation on 1022 students from 13 French-language universities based in Canada, France, Belgium and Algeria indicates that mentors in business, contrary to other mentors, support opportunity identification and exploitation among university students. Although student gender, entrepreneurial experience and education have a more pronounced effect, mentoring is the only element that can be controlled for through the creation of formal support programs. These results call on public authorities, and universities in particular, to implement formal mentoring programs to support students who are interested in starting their own business, and who would not otherwise have access to business mentors in their environment. 相似文献

We propose a valuation method for financial assets subject to default risk, where investors cannot observe the state variable
triggering the default but observe a correlated price process. The model is sufficiently general to encompass a large class
of structural models and can be seen as a generalization of the model of Duffie and Lando (Econometrica 69:633–664, [2001]). In this setting we prove that the default time is totally inaccessible in the market’s filtration and derive the conditional
default probabilities and the intensity process. Finally, we provide pricing formulas for default-sensitive claims and illustrate
in particular examples the shapes of the credit spreads.
