On industrial knowledge bases,commercial opportunities and global innovation network linkages     

Sverre J. Herstad  Heidi Wiig Aslesen  Bernd Ebersberger 《Research Policy》2014

It is commonly argued that we are witnessing a shift from global production networks, driven by the search for markets and lower cost production sites, to global innovation networks (GINs), driven by the search for knowledge. This paper explores how sources of behavioural differentiation derived from the literature on industrial knowledge bases and technological regimes condition the degree of involvement in international innovation collaboration. We find this to be significantly influenced by the nature of knowledge and the cumulativeness of knowledge development, the active use of measures to protect intellectual property, the inherent need to innovate and the opportunity to generate sales from this activity. The likelihood that the firm establishes and maintains a truly global network configuration is influenced accordingly.  相似文献

NY PEDAGOGISK LITTERATUR     

Rune Kvalsund  Irene Velsvik Bele 《Scandinavian Journal of Educational Research》2013,57(1):15-35

This article is based on data from two national research projects in Norway dealing with upper secondary educational reforms that began in 1994. Together, the research projects represent a longitudinal study of prospective life course data from 1995 to 2003, covering approximately 500 students from the time they were receiving special education in upper secondary school to the age of 22. The analysis is based on theories of social networks, frame factors, risk and resilience, and life course transitions. It uses a typology of social marginalization based on the dimensions of network density and network size to capture the differences in framing opportunities and restrictions on the students’ social network relationships in the spare time arena. The study addresses how such relationships in early adult life are affected by earlier school experiences, such as whether they attended special or mainstream classes, compared with personal factors and their family situation at the start of upper secondary school.  相似文献

Centrifugal schooling: third sector policy networks and the reassembling of curriculum policy in England     

Ben Williamson 《教育政策杂志》2013,28(6):775-794

This article examines changes in curriculum policy in secondary education in England. It is concerned with recent curriculum policy and reform, and the proliferation of non-government actors in curriculum policy creation. It examines the emergence of a loose alliance of third sector organisations and their involvement in a series of alternative ‘curriculum experiments’. The third sector curriculum policy network revolves around a policy vision of decentralisation constituted by public–private partnership, media-friendliness, social enterprise and an ‘open source’ or network-based organisational logic. It assembles a policy ideal of ‘centrifugal schooling’ which links together ideas about ‘networked governance’ with ‘flexible’ learning and ‘entrepreneurial’ curricula. The article traces and discusses some of the inter-organisational relations, materials and discourses of the third sector network of alternative curriculum policy developments, and provides a case study of a prototypical third sector curriculum programme. It examines the organisational relations and practices by which the project was produced and the conditions leading to its failure.  相似文献   

The role of social capital in the explanation of educational success and educational inequalities     

Tobias Roth 《Irish Educational Studies》2013,32(3):335-354

This article examines the role that social capital plays in school success and in the explanation of social and ethnic inequalities in the German educational system. Based on Coleman's well-known concept of social capital, different aspects of social capital are distinguished, including social network composition, parent–school interaction and intrafamilial social capital. In sum, the overall results indicate that the different aspects of social capital influence the school performance of pupils. In addition, social capital endowment is found to be of relevance for the explanation of inequalities in school grades between social classes and ethnic groups. In this respect, the analyses indicate that social capital endowment is part of the underlying mechanism responsible for educational inequalities.  相似文献
