Abstract
In this study, international research collaboration (IRC) and international research orientation (IRO) have been studied at the micro-level of individual academics from the university sector (N = 8,466, 11 European systems). Both were studied crossnationally, cross-disciplinarily, and cross-generationally. This study differs from most existing internationalization literature in its sample (Europe) and focus (patterns of internationalization in research), using more standard methods (a multivariate model approach). It addresses questions about the patterns of IRC and IRO, international publishing, and the predictors of IRC, or what makes some European academics more prone to collaborating with international colleagues in research than others. In the context of changing incentive and reward systems in European academic science, which are becoming more output oriented, it is ever more important for individual academics to cooperate internationally (as well as to co-publish internationally). “Internationalists” increasingly compete with “locals” in university hierarchies of prestige and for access to project-based research funding across Europe. Evidence is presented that co-authoring publications internationally is still a rare form of research internationalization in Europe (50.8% of academics co-author publications internationally). However, as compared with other world regions, the percentage of European academics collaborating internationally in research (63.8%) is very high. A striking cross-national differential within the youngest European generation of academics was found, which may be a
strong barrier to intra-European research collaboration in the future.

The Journal of Studies in International Education (JSIE) http://journals.sagepub.com/home/jsi reaches an extensive international audience. It is the premiere forum for higher education researchers, teachers, policy makers, leaders, managers and administrators, interested in all facets of the internationalization of higher education.

JSIE publishes critical scholarly peer reviewed articles from researchers and practitioners in all regions of the world contributing new insights into current and emerging concepts, theories, research and practice in the internationalization of higher education.

The Journal of Studies in International Education is published on behalf of the European Association for International Education (EAIE) on behalf of the Association for Studies in International Education (ASIE), a group of organizations whose mission is to encourage international education and serious research and publications dealing with this topic. As such, the initial objective of ASIE and the primary focus of its activity is support of the publication of JSIE.

It publishes 25-30 papers a year.
