Evidencing academic policy to everyday practice from the Erasmus COALITION project

Beyond the immediately visible plenum, parliaments are highly complex institutions. They work through various venues in which decisions are prepared or even taken. The two main institutions in this regard are parliamentary party groups, which comprise legislators who are elected under the same party…

Mission statement

Our world is shrinking, or at least our electronic devices are. From PCs to mobile phones: everything is smaller and thinner. The smaller the chip, the better it can conduct electricity and pass on information.

Online competitions, online sports, dietary advice for staff and students and 'What do they eat for lunch?' The first 'volunteer' is Vice-Rector Hester Bijl. What does her lunch usually consist of? The University Sports Centre is celebrating its fifty-year anniversary with a whole - corona-proof - programme…

This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

This book expands on the existing literature on the international dimension of democratization by introducing the concept of democracy projection. Democracy projection is defined as the projection of (democratic) norms through the every-day practice of interactions-beyond any donor-recipient relationship-between…
