Investigating the Potential of Data from an Academic Social Network (GPS)

There are several references in the literature highlighting the importance of the international scientific mobility studies and several examples of how this academic population has been characterized. Typically, the analysis of academic mobility has been conducted by applying extensive surveys to a \u201crepresentative\u201d sample, in a specific moment in time, in which the profile of the researchers, that are working or studying in a foreign country, is then inferred. These analyses may suffer of structural lack of representativeness since the target population is unknown. As a structural and inherent issue in this research field, this article presents the results provided by the Portuguese academic social network GPS (Global Portuguese Scientists). It uses a valuable and exclusive data set of the research experiences, provided by Portuguese researchers, to describe and understand the academic dynamic of these researchers over the last years. The analysis considers different socio-demographic characteristics and the type of research (position, scientific research area, duration of the experience) they have been doing. The analysis shows that GPS users are pulled to the core countries of the science world system and points out that each destination of the Portuguese diaspora is associated with specific features of the mobile researchers and their research activity

“Knowledge migrants” or “economic migrants”? Patterns of academic mobility and migration from Southern Europe to Mexico

Because mobility has been described as a key element of the academic habitus and a well‐established norm in scientific life, people moving within academia have been generally considered to be “knowledge migrants” and “talent migrants.” Indeed, the literature rarely takes a labour market perspective when analysing academic mobility. However, Southern European academia is largely characterised by challenging working conditions, low wages, and a lack of fair competition for positons, all of which negatively affecting job prospects. Based on 25 in‐depth interviews, this paper explores the reasons behind the migration of a group of Spanish and Italian academics in Mexico with a view to bringing into focus the role of economic/labour and careerrelated reasons in migration decisions. We find that their experiences fall along three main academic trajectories, which are distinguished by the stage in the participants' careers at which they decided to migrate and the channels by which they entered Mexican academia. Common to all three groups is the identification of the economic crisis and a lack of institutional support as strong motivating factors in their decision. Underlying this is the question of whether the studied group is best viewed as “knowledge”/“talent” migrants who have followed certain institutional channels or “economic migrants” who are somehow pushed to work abroad by the lack of good employment in their countries of origin. The paper also challenges mainstream ideas about academic mobility, in the sense that the literature has not considered the attractive power of universities/research centres located in the Global South
