Diasporas have become a visible phenomenon of our world. Wherever we go in the major metropolitan world centres, we run into not only China and India "Towns", but we also witness the individual faces of old and recent immigrants from a variety of other nations flooding the airports, shopping centres and city parks. The impact of these "worlds on the move" on globalisation, migration and identity negotiations is the subject matter of this book.

The scholarship of Ulf Hannerz is characterized by its extraordinary breadth and visionary nature. He has contributed to the understanding of urban life and transnational networks, and the role of media, paradoxes of identity and new forms of community, suggesting to see culture in terms of flows rather than as bounded entities. Contributions honor Hannerz' legacy by addressing theoretical, epistemological, ethical and methodological challenges facing anthropological inquiry on topics from cultural diversity policies in Europe to transnational networks in Yemen, and from pottery and literature to multinational corporations.

The field of mobility studies examines social phenomena through the lens of movement. In this perspective, societies are regarded as being constantly reconfigured as they are shaped by a series of mobile entities (capital, people, information). This book engages critically with many of the claims and challenges of mobility studies by providing empirically rich reports of mobilities and their limitations. Instead of assuming a seamless world of flows, the volume foregrounds questions of power, inequality, and moorings as integral to the movement of capital, goods, images, practices, or people. It brings together the work of several internationally renowned scholars, who engage with these movements at critical sites. This is the first book to provide a critical and interdisciplinary view of mobilities covering a broad range of issues rather than a single domain. The chapters deal with current and important issues, such as organ transplants, illegal migrations, urban globalization, international policies of higher education institutions, and scientific diasporas. As a whole, the book provides new insights into how power relations shape mobilities and societies.
