干系人私人关系、知识共享行为对复杂产品研发绩效的影响

在文献回顾的基础上,提出了干系人私人关系的三个构成:感情、人情和面子,探讨了干系人私人关系的三个构面、知识共享行为和复杂产品研发绩效之间的关系,构建了理论模型,并以复杂产品研发团队的干系人为调查对象对模型进行了实证研究。研究结果显示:干系人的感情、人情和面子均对知识共享行为有显著的正面影响,感情和面子对复杂产品研发绩效有显著正面影响,知识共享行为对复杂产品研发绩效有显著正面影响。此外,研究结果还表明,知识共享行为在人情和复杂产品研发绩效之间起到了完全中介作用;知识共享行为在感情和复杂产品研发绩效及面子和复杂产品研发绩效之间分别起到了部分中介作用。     

环境、能源、R&D与经济增长互动关系的研究

选取了1998~2012年中国31个省市的面板数据,采用面板协整方程、PVECM模型和PVAR模型,探讨了中国环境、能源、RD与经济增长之间的互动关系。结果表明:环境污染、能源消耗、RD和经济增长之间存在长期的均衡关系,且短期波动偏离长期均衡的正向调整幅度为0.69%;RD主要得益于经济发展,虽然RD水平的提高能够在一定程度上抑制环境污染,但是其却在一定程度上刺激能源消耗;虽然,能源消耗既是经济增长的动力,也是造成环境污染的重要原因,但是其能够在一定程度上促进RD水平的提升;环境污染具有累积效应和路径依赖的特性,且其对经济增长的贡献和对RD的"倒逼"作用相对有限。

The relationship among achievement goals,standardized test scores,and elementary students’ focus in school

The study examined whether an academic, social, or both an academic and social focus might relate with achievement goals and academic achievement. Participants were 412 urban elementary school students. Results suggest that students with an academic focus toward school have more mastery‐approach and less mastery‐avoid achievement goals. Academic achievement (standardized test scores) did not relate with boys’ or girls’ focus toward school. These findings suggest that academic motivation, but not achievement, correspond with self‐perceptions of school as being a place to learn or school as a place for social interactions.

Social orders and interactions among children in age-mixed classes in primary schools – new perspectives from a synthesis of ethnographic data

The article synthesises data from two ethnographic projects, which both explore interactions of children in age-mixed groups in primary schools. It illuminates critical perspectives on social orders and children's interactions in age-mixed classes by showing how pupils in age-mixed groups become involved in power relations and how the teacher's authority and institutional rules are intricately interwoven into the social orders of the peer culture. The article highlights children's complicity with the teacher and her expectations and accordingly questions the notion of an increase of children's autonomy in age-mixed groups.     

Incorporating radiology into medical gross anatomy: Does the use of cadaver CT scans improve students' academic performance in anatomy?

Radiological images show anatomical structures in multiple planes and may be effective for teaching anatomical spatial relationships, something that students often find difficult to master. This study tests the hypotheses that (1) the use of cadaveric computed tomography (CT) scans in the anatomy laboratory is positively associated with performance in the gross anatomy course and (2) dissection of the CT‐scanned cadaver is positively associated with performance on this course. One hundred and seventy‐nine first‐year medical students enrolled in gross anatomy at Boston University School of Medicine were provided with CT scans of four cadavers, and students were given the opportunity to choose whether or not to use these images. The hypotheses were tested using logistic regression analysis adjusting for student demographic characteristics. Students who used the CT scans were more likely to score greater than 90% as an average practical examination score (odds ratio OR 3.6; 95% CI 1.4, 9.2), final course grade (OR 2.6; 95% CI 1.01, 6.8), and on spatial anatomy examination questions (OR 2.4; 95% CI 1.03, 5.6) than were students who did not use the CT scans. There were no differences in performance between students who dissected the scanned cadavers and those who dissected a different cadaver. These results demonstrate that the use of CT scans in medical gross anatomy is predictive of performance in the course and on questions requiring knowledge of anatomical spatial relationships, but it is not necessary to scan the actual cadaver dissected by each student.
