Monetary incentives and social ties in academic publications

Monetary incentives underlie academic publications, especially in countries where many researchers' incomes are performance-based. Evidence has documented that social ties improve the chances of publication in journals, whereas building and maintaining social ties require resources. We develop a simple model to investigate the consequences of monetary investment on the probability of publication through social ties. The results indicate that monetary incentive can stimulate researchers to make more efforts regarding publication. Through social ties, monetary investment in the process of academic publication distorts researchers' incentive. Monetary investment through social ties improves the probability of publication and then disables the signaling function of publication in terms of researchers’ abilities. Depending on the contribution of different types of researchers to society and the ability of the latter to differentiate the quality of publication in journals, the improvement in publication probability by monetary investment through social ties may improve or reduce the level of social welfare.     

社会资本与技术支持对学术虚拟社区知识共享的影响——基于科学网平台的知识共享要素分析

学术虚拟社区是广大学者和科研工作者进行知识交流与探讨的重要平台，也是学术碰撞和知识创新的新阵地。通过构建社会资本与技术支持对用户知识共享行为影响的理论模型，探讨社会资本（关系资本、结构资本、认知资本）和技术支持（感知有用性、感知易用性）对社区用户知识共享行为（知识共享质量和数量）的作用机理。结果表明，关系资本与结构资本分别对学术虚拟社区知识共享质量和数量具有显著正向影响，属于持续动力。伴随其它因素介入，认知资本对学术社区知识共享数量产生正向影响，技术支持对知识共享的影响具有显著差异，感知易用性对学术社区知识共享质量和数量均具有显著正向影响，而感知有用性对知识共享质量具有显著负向影响。基于此，提出社区管理者应采取措施拓展用户社会资本并加强平台技术支持，以实现学术虚拟社区可持续发展。     

美国顶尖大学学术不端行为处理机制研究——以美国四所顶尖大学为例

学术不端行为处理机制是美国顶尖大学尊重学术创新、捍卫学术诚信的重要保障。通过对美国四所顶尖大学处理学术不端行为政策和实践的分析，发现美国顶尖大学学术不端行为处理机制由处理依据、处理主体、处理程序和监督救济构成，在制度保障、组织支持、过程保障和理念引领方面具有以下特征：提供制度规章，确保有章可循；职责分工明确，兼顾专业性和自主性；注重程序规范，保障审理及时严密；坚持以人为本，注重教育为主、惩罚为辅。美国顶尖大学学术不端行为处理机制对我国高校完善学术诚信体系建设具有重要借鉴价值。     

Making sense and transparency in finance literature: Evidence from trends in readability

Transparency continues to interest finance scholarship, as regards not just to financial reporting, but to a host of areas. Concomitantly, there is a growing emphasis on the transparency of the finance research process, with journals initiating requirements for uploading data and codes. However, little consideration is given to the transparency of finance scholarly texts, despite new emphasis by academic institutions and accreditation bodies on articles having an impact on practitioners. We use textual analysis to investigate the readability of articles in a selection of finance journals. Results evidence that academic articles are becoming less readable. Whether readability straightforwardly implies transparency is unclear, still, we consider these issues alongside our findings. Our study should be of great interest to those concerned with the state of finance scholarship.     

Physical activity,leisure-time,cognition and academic grades: Connections and causal effects in Chinese students

Academic achievement and positive leisure activities are traditionally considered significant determinants of economic growth and human capital accumulation. This paper estimates the impact of physical activity on academic outcome and time allocation to 25 different types of leisure activity by Chinese adolescents. We use structural equation models (SEM) to explore the channels of this transmission. Our results suggest that physical exercise not only exerts a positive direct effect on academic outcome but also increases (decreases) students' time devoted to activities that are positively (negatively) correlated with academic outcome. All the effects are statistically significant but modest at the individual level. Our findings are robust to different exercise frequencies and academic outcome indicators based on students' self-assessment, academic scores, and cognitive tests.     

科研诚信“自律”与“他律”协同建设的内在逻辑及现实路径研究

我国在40余年的科研诚信建设过程中，“自律”与“他律”建设均存在不足，两者没有形成有效协同。为加强科研诚信建设，更好地发挥科研诚信系统的整体协同效应，需要运用协同学理论，对我国科研诚信建设系统进行分析，探求系统内部协同机理，促使科研诚信“他律”和“自律”在合作过程中产生协同效应，并通过优化科研诚信建设子系统各要素，加强系统与环境之间的合作，发挥科研诚信建设系统的最优协同效应，进而构建我国科研诚信建设全方位协同治理体系。
