Social cohesion in Rwanda: Results from a public good experiment

We describe a public good experiment, a type of economic experiment commonly used to examine feelings of prosociality—that is, behaviour which is positive, helpful and intended to promote social acceptance and friendship—and community cohesion, carried out in Rwanda. Contributions in different parts of the country are affected by the local intensity of the 1994 genocide, with more generous contributions being made in areas where violence was greater. This supports earlier research indicating that conflict experience leads to greater prosociality. However, we also find that people who have not, themselves, been targets of violence give lower contributions than people who have. The considerable group‐related and regional differences in social behaviour may have implications for the country's policies to deal with social cohesion.     

Social network effects on academic achievement

How peer groups contribute to educational outcomes has long interested researchers. However, the possibility that peer groups dominated by either low- or high-achieving youth can have substantively different effects on achievement has been largely ignored. In this paper, we show that while being embedded in a high-achieving network of friends is not associated with increased own achievement, being embedded in a low-achieving network is associated with decreased own achievement. In additional analyses, we present evidence that these associations are at least in part due to influence, as opposed to only selection effects or shared environment. We also examine whether the structure of the network in which a student is embedded might affect their educational achievement. We show that achieving at higher levels positively predicts how centrally located a student is in their network, but being more centrally located does not predict concurrent achievement. This finding suggests that the behavior of individuals is affecting the formation of network structure and not the reverse.

略论皮埃尔·布迪厄的人类学思想

皮埃尔·布迪厄的人类学研究及其成就,是当时法国社会与政治条件的结果,更是他的人生阅历及学术旨趣的直接产物。他的人类学成果是多方面的,不仅是其学术思想的灵感来源和认识论反思的基础,而且促成了他“从规则到策略”的转变。可以说,人类学研究是布迪厄一生学术思想的逻辑起点。

Information Sharing in a Manufacturer–Supplier Relationship: Suppliers' Incentive and Production Efficiency

While there have been vast discussions on the materialistic benefits of continuous improvement from the Toyota and Honda experiences, the academic literature pays little attention to information sharing. In this study, we construct a dynamic adverse selection model in which the supplier privately observes her production efficiency, and in the contractual duration the manufacturer obtains an informative but imprecise signal regarding this private efficiency. We show that despite the disclosure of proprietary information, information sharing may benefit the supplier; the supplier's voluntary participation is more likely to occur when the shared information is rather imprecise. On the other hand, our analysis also reveals that this information sharing unambiguously gives rise to an upward push of the production quantity, and may sometimes lead to an upward distortion that ultimately hurts the supply chain. We also document the non‐trivial impact of the timing of information sharing on the supplier's incentive to participate.     

国际化学院的课程体验调查分析

北京航空航天大学中法工程师学院通过中外合作的办学模式以实现国际化人才的培养,其重要途径之一就是通过对课程体系进行的改革,而人才培养的质量很大程度上也取决于所授课程的质量。运用一种在国际上普遍采用的课程质量调查方法———大学生课程体验调查,结合国际化学院的特殊背景修订问卷,对北航中法工程师学院与普通学院的学生进行课程体验的调查。调查发现,北航中法工程师学院学生对课程的满意程度高于普通学院学生,特别在良好教学与资源获取方面明显好于普通学院学生,但在课程收获和学业负担方面仍需改进。
