Collaborations in funded teams are essential for understanding funded research and funding policies, although of high interest, are still not fully understood. This study aims to investigate directed collaboration patterns from the perspective of the knowledge flow, which is measured based on the academic age. To this end, we proposed a project-based team identification approach, which gives particular attention to funded teams. The method is applicable to other funding systems. Based on identified scientific teams, we detected recurring and significant subgraph patterns, known as network motifs, and under-represented patterns, known as anti-motifs. We found commonly occurred motifs and anti-motifs are remarkably characterized by different structures matching certain functions in knowledge exchanges. Collaboration patterns represented by motifs favor hierarchical structures, supporting intensive interactions across academic generations. Anti-motifs are more likely to show chain-like structures, hindering potentially various knowledge activities, and are thus seldom found in real collaboration networks. These findings provide new insights into the understanding of funded collaborations and also the funding system. Meanwhile, our findings are helpful for researchers, the public and policymakers to gain knowledge on research(ers) evolution, particularly in terms of primordial collaboration patterns. 相似文献

ABSTRACTFor librarians at the University of North Florida, there was a need to move beyond information literacy instruction to one-on-one and small group research consultations to aid in student success. By staffing the research desk with staff and students, librarians were able to open their calendars to allow more time for in-person, phone, and online consultations to aid in meeting the research goals of students at the institution. After assessing the research consultation program for two years, there has been a positive correlation between research consultation usage, satisfaction in completing assignments, and student success measures throughout the university. 相似文献

Over the past decade, the field of sport-for-development (SFD) has experienced significant growth and diversification across research and practice. In this review paper, the authors provide a comprehensive analysis and discussion of the theoretical and conceptual developments within SFD, addressing a gap in the literature. Following a sport-focused review of SFD literature, the authors first identify five theoretical and conceptual frameworks that have emerged from within the SFD space. As a second step, they analyze and discuss scholarly work that has utilized these theories and frameworks. Building on a comparison of key messages, themes, and concerns, the authors highlight that to date, limited SFD scholarship has truly applied, extended, or challenged existing frameworks and conceptualizations. Motivated by this review, they posit several conceptual advancements, and offer directions for future research and theoretical development. 相似文献

ABSTRACTWhat is the place of the diasporas within the Inter-Asia Cultural Studies movement, and how can Asian diasporas in the West contribute to Inter-Asia's intellectual project of “problematising Asia”? Developing a notion of diaspora as method, this essay highlights the complementary relationship between the Asian Australian Studies Research Network and the Inter-Asia Cultural Studies network. It argues that the Inter-Asia network has much to gain from embracing the Asian Australian diaspora as an interlocutor with shared priorities and concerns, and that Asian Australian studies can also productively learn from Inter-Asia's alternative model of institutionalisation, thereby expanding its theoretical and methodological frames of reference. 相似文献

ABSTRACTThis article suggests that situations in which multiple research teams are convened under similar conditions present an opportunity to discover factors that lead to productive collaboration. It argues that social network analysis of research team outputs becomes more valuable when paired with data about research participant perceptions; and that any variables used as indicators of collaboration need to be calibrated using datasets from multiple studies with cross-team comparisons. The article provides an example of the kind of methodology needed to achieve this, describing a study with data from four research teams based at an Australian university campus, reporting their research performance over four years under conditions in which many variables were controlled and with results augmented by a survey of participant perceptions. Findings from the study indicate that there were exceptions to hypothesized associations between participant perceptions of collaboration and specific social network analysis measures over co-authorship data. The article suggests that, given the methodological challenges of studying research teams in the field, multiple datasets combining findings such as those in the present study are a path towards the development of indicators of productive higher education research collaboration. 相似文献

ABSTRACTThe aims of this study were to identify profiles of sedentary behaviour (SB) patterns, based on leisure-time self-reported SB modalities (screen, educative, social, and relaxing) and to evaluate changes in these profiles over 2 years among Spanish youth aged 8–18 years. Latent profile analysis (LPA), a data-driven analytic approach, was used to identify groups of boys and girls (n = 1553; 48% girls; mean±SD age: 12.56 ± 2.49 y) with distinct SB profiles using the SB modalities (time/d) as input variables. Latent transition analysis, an extension of LPA that uses longitudinal data, was used to analyse 2-year changes in these profiles. At baseline, four and three SB profiles were found among boys (labelled: screen, educative, social, and relaxing) and girls (labelled: screen/social, educative, and relaxing), respectively. Overall, more girls (range: 48%-67%) had the same profile over time, than boys (40%-52%). Participants with a screen or relaxing SB profile at baseline were more likely to have an educative profile after 2 years. Youth with a social and an educative SB profile at baseline were more likely to transition to profiles characterized by higher screen and social SB, respectively. Using a novel and person-centered approach, this study identified gender-specific SB profiles that were moderately stable over time. 相似文献

The study focuses on the research performance of Double First-Class (DFC) universities in China. A theoretical framework based on economic theory and the Analytic Hierarchy Process (AHP) method for a novel evaluation model is proposed. The model is performed on a sample of 41 participant DFC universities in China. Using data collected from these universities, it was found that there is no consistency between performance ranking, input ranking, and output ranking, with the best ranked universities far from the most efficient. These findings provide empirical evidence of DFC universities’ research performance situation and suggest strategies that the government can use to propel their sustainable development. 相似文献

Using a tripartite framework, this study examines the current level of coordination among human resource development (HRD), research, and industry in four South Asian countries—Bangladesh, India, Nepal, and Sri Lanka. Drawing on prior literature, statistical data, and opinions from local experts, this study found that university education oft lacked labor market relevance, and that collaboration efforts between universities, research institutes, and industries had much room for improvement. To promote coordination among HRD, research, and industry for knowledge and technology-driven economic development in South Asia, this study recommends that inclusive coordination should be given higher priority over bilateral university-industry linkages. This study also argues in favor of a government-led approach in the short term, to complement the current laissez-faire approach. This study ends with policy recommendations to enhance coordination and governance based on the above-mentioned findings. 相似文献
