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

ABSTRACT

This study is an exploration of how Association of Research Libraries (ARL) member institutions encourage and support their librarians engaged in research and publication. Using an online survey sent to members of the ARL library directors’ listserv, the authors gathered information about the role of research and publication in the respondents’ evaluation systems, the approaches used to support this activity, the respondents’ own records of research and publication, and their opinions about which approaches have the most impact. The results indicate that funding, time, and mentoring are the most frequently used approaches to promote research and publication productivity.  相似文献

Public visual spaces, populated by a blend of community murals, unauthorised street art, and historic painted mercantile signs, are often the mark of an urban environment that is both progressive and eclectic. Changes in the aesthetic and cultural value of these urban mural forms have led to an increase in the appreciation and, in some instances, promotion of their artistic merit and cultural significance as examples of public art. However, examining the significance of these works, with a view to implementing a conservation approach is problematic. This is due to a number of practical and theoretical considerations that are primarily a result of the ephemeral existence of urban murals outside conventional exhibition spaces, and issues associated with their often fragmented ownership and uncertain authorship. Consequently, larger thinking on the interpretation, conservation assessment, and advocacy for the conservation of urban murals are required. Key to defining and implementing such strategies is contextualising the public visual spaces that these murals occupy and, as part of this, the local and wider communities’ perception of these murals as culturally significant objects as well as fostering awareness and understanding of appropriate measures aimed at their conservation. This paper examines the role of citizen science, or crowd-sourcing, of local community members in establishing a conservation dialogue and generating conservation- relevant data on urban murals. It looks specifically at a project involving a collection of in situ historic painted mercantile signs — also known as ghost signs — in the City of Port Phillip, Melbourne, Australia. The project fostered the establishment of an informed and open dialogue between conservation specialists and participants from the local community on the significance of local ghost signs whilst transferring knowledge on conservation processes and assessment methods. Working directly with community members, a programme was designed in which conservation and community knowledge of these urban art forms, could be collected and exchanged across digital platforms. This enabled researchers to examine how citizen science can be utilised as a research tool as well as a means to advocate for the conservation of collections of urban murals. It created the opportunity to consider the role of non-specialists and shared authorities in the collection and collation of conservation- relevant data and how information generated from what we call citizen conservation projects, can inform the way in which conservators evaluate and prioritize the conservation of urban cultural heritage. The data gathered and interpreted proved to be the most effective means of ‘conserving’ these often ephemeral forms of cultural material.  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

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

This paper discusses some findings from a small‐scale qualitative study involving ‘new’ teachers in a medium sized, regional English university. Using Grounded Theory methods to inform and guide the research, the study explores participants’ views on working as both teachers and researchers whilst also managing considerable amounts of ‘caring work’ with a diverse body of students who often need academic and pastoral support in excess of that assumed within the university academic timetables or support networks. The voices of these teachers suggest that care is an overlooked aspect of university teachers’ work, yet it plays an important part in maintaining their and their students’ sense of scholarly endeavour. Further, our findings suggest that within the university at large there is a ‘discourse of difference’ in the way that many academics conceptualize and represent the student body and students’ needs to be supported. This discourse impacts on the development of new teachers’ identities and aspirations. Some implications of these findings for implementing strategies for supporting teachers to develop both academic and pastoral roles within universities are discussed.  相似文献

Suzy Q's is a retail business located in the southeastern United States. It offers hand‐knitted scarves; handmade hair accessories; handcrafted beaded jewelry such as necklaces, bracelets, and earrings; small handmade children's toys; and stock and custom‐printed T‐shirts. It began operations in early 2014. The owners established an online store and developed plans to sell items at local craft fairs and farmers’ markets in the southeastern United States. During its initial launch, the business generated limited orders for its products. In the beginning there was a limited amount of advertising using social media, which consisted of establishing a Facebook page, posting notifications on the business's Facebook page, and posting notifications about the business to the owners’ personal contacts on Facebook. Despite establishing a web presence and utilizing social media in its first year of operations, Suzy Q's did not generate a significant number of orders and received very little revenue. The owners of Suzy Q's, our client, established a goal to generate at least $700 per month in revenue for the calendar year 2015. Our analysis of the business revealed that the managers and employees had the skills needed to perform the work, but the lack of orders presented an obstacle to achieving their business goals. After completing a performance analysis, we recommended that Suzy Q's establish a single online presence, implement a marketing effort, establish a local presence, create a dedicated studio space, and create a formal business plan. It was our belief that Suzy Q's had the potential to reach its goals set for 2015 and beyond if these solutions were implemented.  相似文献
