International doctoral students as knowledge brokers: reciprocity,trust and solidarity in transnational networks

In this article, we examine the role of brokerage, the knowledge that brokers transfer and the social conditions of that transfer. Previous research suggests that highly skilled migrants spanning multiple locales have the advantage of being able to transfer knowledge as they move from one place to another. In this study, using a network perspective, we look at the activities of international doctoral students in their transfer of knowledge and illustrate the underlying social conditions of knowledge transfer through transnational friendship networks. Using a qualitative methodology, we examine the research questions and 35 in‐depth interviews, as well as egocentric network analysis conducted in Germany. In the findings, we explore the social conditions of knowledge brokerage, including trust, reciprocity and solidarity. Finally, we discuss the implications for further research on knowledge sharing among brokers and international students.

Technology,offshoring and the task content of occupations in the United Kingdom

The authors analyse change in employment levels and in the task content of occupations, both within occupations (i.e. at the intensive margin) and between occupations (i.e. at the extensive margin) in the United Kingdom over the period 1997–2006 using data from the national Skills Survey, which has comparable within‐occupation task data for three waves: 1997, 2001 and 2006. They find that within‐occupation task content changed significantly, and that the magnitude of change was similar to that found at the extensive margin. Their econometric results suggest that these intensive‐margin shifts can be explained by technological improvements but not by offshoring.

哲学实验与实验哲学

“实验哲学”与“哲学实验”既有区别又有联系,不能混为一谈.哲学实验是一种独特的哲学研究的新方法,而实验哲学则是一种新的哲学流派,在实验哲学研究中主要采用的是哲学实验方法,这种方法对于完善哲学研究方法具有重要意义;在国内刊物和书籍中一些作者错把“哲学实验”与“实验哲学”等同起来,哲学实验和实验哲学的兴起进一步说明了数学和哲学二者的界限已经变得越来越模糊.
