Directed collaboration patterns in funded teams: A perspective of knowledge flow     

《Information processing & management》2023,60(2):103237

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   

Assisting,Instructing, Assessing: 21st Century Student Centered Librarianship     

Lauren Newton  Daniel E. Feinberg 《The Reference Librarian》2020,61(1):25-41

ABSTRACT

For 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   

Sport-for-development: A comprehensive analysis of theoretical and conceptual advancements     

《Sport Management Review》2020,23(5):783-796

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

基于熵权-TOPSIS模型的大风浪条件下引航员登船水域选址     

周宁  范中洲  赵羿 《上海海事大学学报》2020,41(1):46-50

为保障大风浪条件下引航员登船安全、周边船和被引船的安全以及港口的安全高效运营,选取合理的引航员登船水域至关重要。综合考虑熵权法和TOPSIS法的优点,基于熵权-TOPSIS模型对大风浪条件下引航员登船水域进行优选研究。以大风浪条件下广州港引航员登船水域选址为例,运用该模型对3个备选方案进行评价,求得方案2的相对贴近度最大。该方案所述的引航员登船水域为大风浪条件下最优登船水域,且与实际选址一致。经实例验证,该模型较为可靠,实用性强。  相似文献   

纳米流体液滴撞击固体壁面的实验和模拟研究     

王睿  沈学峰  霍元平  王军锋  郑诺  刘海龙 《中国科学院大学学报》2020,37(2):281-287

液滴撞击固体壁面现象常见于动力机械、喷雾冷却和薄膜材料沉积制备等工业生产中。将石墨烯和碳纳米管作为分散颗粒，应用超声波分散技术制备均匀性与稳定性良好的树脂基纳米流体。利用高速摄像技术，研究纳米流体液滴撞击固体壁面的动力学行为。基于有限元法，通过修正的幂律黏度模型耦合纳米流体的剪切变稀特性，采用水平集方法捕捉相界面的移动，建立纳米流体液滴撞击固体壁面的数值模型。模拟结果与实验结果较好一致，验证了数值模型的正确性与准确性。研究发现实验配制的纳米流体表现出非牛顿剪切变稀特性，纳米颗粒的加入抑制了液滴撞击固体壁面过程中的铺展和回缩行为。随着幂律指数m的减小，液滴撞击固体壁面后的铺展范围变大。随着表面张力的增大，液滴的无量纲直径在铺展阶段无明显变化，但在回缩阶段逐渐减小。  相似文献   

一种基于模糊语言TOPSIS的应急决策方法     

李海明  虞钢  田崇鑫  尚国彬 《中国科学院大学学报》2020,37(6):814-819

在应急决策过程中，决策信息通常具有犹豫性、模糊性和非对称性，且决策者呈现出直观、快速的语言决策偏好。提出一种基于模糊语言TOPSIS的应急决策方法，使用犹豫模糊语言术语集和二元语义表达式对高度不确定环境下的语言进行处理，提高对犹豫模糊语言信息的提取能力，生成易于理解的语言评估结果，从而辅助决策者进行快速、准确的决策判断。案例证实该方法的可行性与有效性，为解决应急决策问题提供了一种新方法。  相似文献
