Diaspora and transnationalism are concepts that have become very popular in modern academic and political discourses. And while most of the new literature treats the two separately, this book studies these fields alongside one another. Rainer Bauböck and Thomas Faist bring together scholars from a wide range of academic disciplines to discuss the concepts, theories, and methodologies used in the study of border-crossing affiliations. --From publisher's description.Diaspora &​ transnationalism are widely used concepts in academic &​ political discourses. Although originally referring to quite different phenomena, they increasingly overlap today. Such inflation of meanings goes hand in hand with a danger of essentialising collective identities. This book analyses this topic.
