The term "transnationalism" has gained considerable academic and popular currency despite a lack of clear definitions, in part because its overall form changes as its influence incorporates additional spheres of daily life on a variety of scales and contexts. The purpose of this volume is to bring together different perspectives on this phenomenon, using case studies that represent some of the most current thinking on "transnationalism" in a wide range of disciplines. Central themes which this book explores include legal and economic reactions to transnational migration; the (re)negotiation of identities in the context of changing national, social and cultural identities; and the emergence of new imaginings of home and social space in transnational communities. The text foregrounds powerful transnational forces crossing the boundaries of nation-states, and at the same time, gives attention to the continued significance of the nation-state and the diversity of localized reactions to transnational challenges.
