Simultaneously, higher education students are recurrently asked to complete course and teacher evaluations online and to participate in small-scale research projects of fellow students, potentially leading to survey fatigue among student populations across the globe. One of the most frequently reported effects of over-surveying is a decrease in overall response rates. This situation has significant impacts on the generalizability and external validity of findings based on web surveys. The collection of reliable data is, nevertheless, crucial for researchers as well as educational practitioners and administrators, and strategies should be developed for achieving acceptable response rates. This paper reports on a methodological experiment (N = 15,651) conducted at the University of Antwerp, Belgium, in which possible strategies to improve survey response are explored. I specifically focus on the impact of an extra reminder as well as specific reminder contents on response rates. The results reveal that extra reminders are effective for increasing response rates, but not for diversifying the sample.

Higher education is one of the social fields where inequalities are produced and reproduced. Nevertheless, we still know very little about the ways in which heterogeneities and inequalities have been experienced and interpreted by those involved in international academic mobility. In this introductory editorial, we consider some of the crucial conceptual issues involved in the study of the nexus between inequalities and international academic mobility. First, we argue that it is important to take manifold inequalities into account when examining this nexus. After all, inequalities can be detected at different levels, and the mobility process is structured around multiple heterogeneities rather than by a single one. Second, we discuss how international academic mobility and inequalities attached to it go beyond nation-state borders. Third, we argue it is beneficial to extend the scope of to the mobility process as a whole, as inequalities in opportunities and outcomes are intrinsically connected.

In recent years, organised student mobility within the European space has increasingly caught the interest of scholarly researchers. As the focus of most research projects has been on the outcome of mobility programmes, studies into the determinants of credit student mobility remain rather focused on individual decisionmaking. However, in order to gain a more profound understanding of how students' motivations to participate in international mobility programmes are shaped, we have to go a step further. Therefore, in this paper, we present a study into the determinants of intraEuropean student mobility, conducted in Austria, Belgium, Italy, Norway, Poland, and UK, taking into account students' personal background and motivations. The results are based on an online survey (n = 5654) and in-depth interviews and focus groups with non-mobile as well as ex-mobile students (n = 71). The results show that mobility decisions are socially and biographically embedded. Moreover, we provide evidence that the decision to spend a study period abroad cannot be fully understood without taking into consideration the macroeconomic context.

In recent years, the European Union (EU) passed through a significant economic crisis. All across Europe, European young people are among the groups which are hit hardest, with youth unemployment rates rising to over 50% in member states such as Greece and Spain. In the classical migration literature, it is suggested that such unfavourable economic climate would make people more likely to move abroad. Whereas in press releases we are regularly confronted with stories about South European young adults with tertiary education working in bars in Northern European cities, limited empirical evidence exists as such on the relationship between the recent Euro-crisis and migration aspirations. This paper addresses this gap in the academic literature. Using data from Flash Eurobarometer 395, I investigate which micro-and macro-level characteristics influence migration aspirations of young people across the member states of the EU. The results reveal the importance of individual characteristics and feelings of discontent with the current climate in explaining migration aspirations. Furthermore, I detect a negative relationship of relative welfare levels with migration aspirations, and a positive relationship of the youth unemployment ratio. Together, the results suggest that potential young intra-EU movers are positively selected from the population.
