Innovation in regions: What does really matter?   总被引:5,自引:0,他引:5  
The literature on systems of innovation conceptualises innovation as an evolutionary and social process of collective learning. But three main questions remain open: is this learning process rather internal or external? What are the boundaries of this process? Is this social process voluntary or rather unintended? This paper strives to tackle those questions by analysing the determinants of regional innovative levels in French manufacturing industries. By estimating a knowledge production function we find that building external interactions is of greater importance than developing internal innovative competences. Second, unintended knowledge flows have less influence on regional innovative performance than deliberate ones. Lastly, the French innovation system looks regional rather than sectoral.  相似文献

Different approaches have been used to analyse international collaboration in science but none can fully explain its rapid growth. Using international co-authorships, we test the hypothesis that international collaboration is a self-organising network. Applying tools from network analysis, the paper shows that the growth of international co-authorships can be explained based on the organising principle of preferential attachment, although the attachment mechanism deviates from an ideal power-law. Several explanations for the deviation are explored, including that of the influence of institutional constraints on the mechanism of self-organisation.  相似文献

This article examines the traditional roles of assessment and the current demands for assessment to ‘gear up’ education systems in response to global economic changes. It argues that in the next millennium, and with the information revolution, it will be important to foster higher order skills and good learning strategies in a high proportion of our students. The article goes on to consider, set against the critical relationship among high-stakes testing, teaching and learning, the nature of high-quality assessment programmes. It will present evidence of impact of the national assessment programme on teaching in England and Wales in the United Kingdom.  相似文献

“This is the thing I really get excited about. There are some great ideas here, some really neat projects. Wanda and Joan are working on amphibian decline. Ann is interested in territorial behavior or some sort of feeding behavior in crawdads. That is a good one to study because crawdads are an important decomposer in the stream. We're looking at what kinds of criteria in a stream make it habitable for different kinds of organisms. And when you see those different combinations of organisms, what do they mean? How do you interpret them? I mean we're really getting into higher levels of thinking, because we're looking at different kinds of organisms and interpreting them in terms of stream health.” Jake, biology teacher, Northwestern High School. © 2000 John Wiley & Sons, Inc.

Despite the vast literature on knowledge management, little research has addressed the specificities of knowledge integration at the cluster level. Moreover, the literature on clusters has not focused on the role that governance may play in knowledge management. Anchored in a knowledge-based perspective, this paper aims at bridging the two fields, filling the gap by analysing the role of cluster governance in knowledge management. An empirical study of two small French firm clusters was carried out based on 29 interviews. The data analysis consisted essentially in content analysis. The clusters studied were characterized by distinct knowledge management processes. In both cases, governance was necessary in order to support knowledge integration by member firms. Our results suggest that establishing an initial common knowledge base seems to be a prerequisite in order for the external knowledge identification and acquisition processes to take place. The activist role played by governance also seems more efficient than that of a broker. We discuss these results and their implications for policy-makers and cluster members.  相似文献

It is generally accepted that talk enriches children's interpretations of texts in literature circle discussions. However, the nature of that talk and exactly how it facilitates interpretation of texts has not been much analysed. This article describes some work undertaken with a class of Scottish children, aged 9–10, to introduce them to the idea of literature circles. The literature circle discussions were then recorded and analysed. The purpose of the project was to record the kinds of exchanges, chains of comment and range of discourses and voices that children used when talking among themselves, and to reflect on their function and value. It was found that a lot of the talk was exploratory though not always in the sense proposed by Mercer. In his terms much was ‘cumulative’. Some talk veered towards anecdotal chat. The children also frequently put on voices not their own, mimicking characters in the story they were reading, and other people they knew. These forms of talk are not always encouraged in the classroom, their effectiveness for learning being in doubt. This article argues that cumulative talk, the telling of anecdotes and the performing of different characters' voices all have a useful function in discussions of books: they can encourage engagement, be helpful in bringing texts to life and advance children's thinking about literature.  相似文献
