Collaboration can be described using layered systems such as the article–author–institute–country structure. These structures can be considered ‘cascades’ or ‘chains’ of bipartite networks. We introduce a framework for characterizing and studying the intensity of collaboration between entities at a given level (e.g., between institutions). Specifically, we define the notions of significant, essential and vital nodes, and significant, essential and vital sub paths to describe the spread of knowledge through collaboration in such systems. Based on these notions, we introduce relative and absolute proper essential node (PEN) centrality as indicators of a node's importance for diffusion of knowledge through collaboration.We illustrate these concepts in an illustrative example and show how they can be applied using a small real-world example. Since collaboration implies knowledge sharing, it can be considered a special form of knowledge diffusion. 相似文献

Distributed R&D, cross-regional knowledge integration and quality of innovative output 总被引:2,自引:0,他引:2
Jasjit Singh 《Research Policy》2008,37(1):77-96
We explore the impact of geographic dispersion of a firm's R&D activities on the quality of its innovative output. Using data on over half a million patents from 1127 firms, we find that having geographically distributed R&D per se does not improve the quality of a firm's innovations. In fact, distributed R&D appears to be negatively associated with average value of innovations. This suggests that potential gains from access to diverse ideas and expertise from different locations are, on average, offset by difficulty in achieving integration of knowledge across multiple locations. To investigate whether the innovating teams that do manage cross-fertilization of ideas from different locations achieve more valuable innovations, we analyze innovations for which there is evidence of such knowledge cross-fertilization along any of the followings dimensions: knowledge sourcing from other locations within the firm, having at least one inventor with cross-regional ties, and having at least one inventor that has recently moved from another region. Analysis along all three dimensions consistently reveals a direct positive effect cross-regional knowledge integration has on innovation quality, as well as a positive interaction effect of cross-regional knowledge integration and distributed R&D for innovation quality. More generally, our findings provide new evidence regarding the importance of cross-unit integrative mechanisms for achieving superior performance in multi-unit firms. 相似文献

以收录于Web of Science的国家自然科学基金资助论文为对象,从高被引论文和平均引用影响两个视角,评价我国与G7国家的合作效果。研究表明,美国是第一大合作伙伴,加拿大、日本、英国、德国和法国与我国的合作规模相当,意大利与我国合作最少;在提升国际合作影响力(高被引论文份额和平均引用影响)方面,NSFC对数学、化学与化工、以及物理学与材料科学领域的提升作用明显,但这种提升效果因合作国家不同而异;NSFC资助对国际合作影响力提升作用较好的领域也是我国总体上实力相对较强的领域,而需要付出更大努力的是我国影响力远低于世界平均水平的领域(如环境与生态学、神经科学与行为学、微生物学、分子生物学与遗传学、以及临床医学等),NSFC资助的国际合作效果甚至不及非NSFC资助的国际合作。文末提出资助政策建议。 相似文献

The purpose of this case study was to ascertain if college students’ information literacy improves through a faculty-librarian collaboration involving a session of library instruction as part of a regular political science course. The authors conducted two surveys to determine if in-person library instruction increases students’ research abilities. The authors surveyed political science faculty to discover their attitudes toward library research instruction. They also surveyed political science students to gauge their opinions on the value of library instruction and to see if there is a connection between their research proficiencies and instruction by a librarian. Through this case study, the authors found that such instruction does improve information literacy. The researchers concluded that for faculty and colleges interested in improving information literacy skills in undergraduate political science students, such library instruction is helpful towards that goal. 相似文献

This paper presents a statistical analysis of the relationship between three science indicators applied in earlier bibliometric studies, namely research leadership based on corresponding authorship, international collaboration using international co-authorship data, and field-normalized citation impact. Indicators at the level of countries are extracted from the SIR database created by SCImago Research Group from publication records indexed for Elsevier’s Scopus. The relationship between authorship and citation-based indicators is found to be complex, as it reflects a country’s phase of scientific development and the coverage policy of the database. Moreover, one should distinguish a genuine leadership effect from a purely statistical effect due to fractional counting. Further analyses at the level of institutions and qualitative validation studies are recommended. 相似文献

Global health is becoming an increasingly important component of medical education. Medical libraries have an opportunity to assist global health residents with their information needs, but first it is important to identify what those needs are and how best they can be addressed. This article reports a collaboration between global health faculty and an academic medical librarian to assess the information needs of global health pathway residents and how assessment data are used to create a multicomponent program designed to enhance global health education. 相似文献

Academic libraries regularly collaborate with faculty at their institutions for information literacy and reference support, but large-scale event series often require different kinds of partnerships. At the Scholes and Herrick Libraries of Alfred University in the fall of 2015, we hosted a traveling exhibit from the National Library of Medicine called “Harry Potter's World” and built an extensive outreach program around it. By collaborating more widely—with student groups, other campus departments, and institutions within the surrounding community—we were able to dramatically increase the reach of our program. This article explores lessons learned in that process and some best practices for external collaboration. 相似文献

ABSTRACTKinesiology emerged from its preventative medicine and education roots to establish itself as a recognized field of inquiry with numerous sub-disciplines. This article presents four trends in modern science that will likely influence the future of kinesiology sciences. Will recent increases in greater scientific specialization be overcome by the need for greater integration and collaborative research? Will recent increases in emphasis on “greater impacts” from funded research continue? Will new kinds of review and journals replace traditional emphases on prestigious, peer-reviewed journals? Will advancements in technology increase complexity and integration of kinesiology sciences? With attention to the dangers and opportunities in these four trends, kinesiology faculty are well positioned to increase the visibility and funding of kinesiology sciences. 相似文献
