The Annual Conference 2019 on “Bilding Bridges” of The Academy of Europe – Academia Europaea (AE), took place on October 23-25, 2019 in Barcelona. AE welcomed a large number of new members, including GLO Fellows Marco Vivarelli (Università Cattolica-Milano) and Douglas S. Massey (Princeton University), and saw a larger number of academic sessions of high quality and interest. Klaus F. Zimmermann, Professor Emeritus of Bonn University, UNU-MERIT, Maastricht University and President of the Global Labor Organization was also present in his role as Chair of the AE Section “Economics, Business and Management Sciences”. In a joint meeting of AE Classes A1 (Humanities) and A2 (Social and Related Sciences) chaired by AE Class Chairs Poul Holm (Trinity College Dublin, A1) and Björn Wittrock (Swedish Collegium for Advanced Study, A2), Marilyn Strathern, University of Cambridge, provided a lecture on “Counting People”. Her contribution was debated by Kirsten Drotner (University of Southern Denmark) and through a very lively discussion of the members of both classes. More pictures.
