How can clusters sustain performance? The role of network strength, network openness, and environmental uncertainty 总被引:2,自引:0,他引:2
This paper draws on social network theory to develop a model of regional cluster performance. We suggest that high performing regional clusters are underpinned by (1) network strength and (2) network openness, but that the effects of these on the performance of a cluster as a whole are moderated by environmental uncertainty. Specifically, the positive effects of network openness on cluster performance tend to increase as environmental uncertainty increases, while the positive effects of network strength on cluster performance tend to decrease as environmental uncertainty increases. Our findings have theoretical and practical implications for social network research in general, and cluster research in particular. 相似文献

In collaborative problem solving, children produce and evaluate arguments for proposals. We investigated whether 3- and 5-year-olds (N = 192) can produce and evaluate arguments against those arguments (i.e., counter-arguments). In Study 1, each child within a peer dyad was privately given a reason to prefer one over another solution to a task. One child, however, was given further information that would refute the reasoning of their partner. Five-year-olds, but not 3-year-olds, identified and produced valid and relevant counter-arguments. In Study 2, 3-year-olds were given discourse training (discourse that contrasted valid and invalid counter-arguments) and then given the same problem-solving tasks. After training, 3-year-olds could also identify and produce valid and relevant counter-arguments. Thus, participating in discourse about reasons facilitates children’s counter-argumentation. 相似文献

Securing quality and equity in education: Lessons from PISA 总被引:2,自引:0,他引:2
Andreas Schleicher 《Prospects》2009,39(3):251-263
Results from PISA show that strong educational performance, and indeed significant improvement over short periods of time,
is possible. Whether in Asia (e.g., Japan and Korea), in Europe (e.g., Finland) or in North America (Canada), many countries
display strong overall learning outcomes; equally important, they show that poor performance in school does not automatically
follow from a disadvantaged socio-economic background. Furthermore, some countries show that educational success can become
consistent and predictable, with very little variation in performance across schools. These countries set the goals to which
others can aspire. This article sets out some of the key policy levers that are associated with high levels of quality in
students’ learning outcomes as well as an equitable distribution of learning opportunities as measured by PISA. 相似文献

This paper uses Conversation Analysis to investigate the ways in which participants in an online asynchronous postgraduate reading group managed and negotiated their contributions within the discussion. Using the conversation analytic concerns with sequential organisation, adjacency pairs and topicality, this article shows the analytic insights that this perspective can bring to the examination of written asynchronous discourse. The paper shows that in the section of the discussion analysed here, the discourse displayed remarkable similarities to the ways in which face-to-face conversation has been seen to operate in terms of the organisation of conversational turns, the application of specific interactional rights, the lineal development of topics of conversation and the structural use of question-answer turn pairs. The paper concludes by showing how this form of analysis can relate to the formation of reflexive pedagogy in which course design can be created to take account of such findings. It shows how a detailed understanding of how pedagogy is played out in interaction is fundamental for reflecting on the relationship between pedagogic aims and educational practice. 相似文献

Aggregate unemployment may affect individual returns to education through qualification-specific responses in participation and wage bargaining. This paper shows that an increase in regional unemployment by 1% decreases returns to education by 0.005 percentage points. This implies that higher skilled employees are better sheltered from labour market changes with respect to their jobs but they encounter larger wage changes than less skilled employees. We use representative individual data and panel variation in unemployment between German regions and employee groups. We demonstrate that our results are robust with respect to aggregation bias, time lags and potential endogeneity of the unemployment variable. 相似文献
