This interdisciplinary anthology addresses the criticism that previous investigations of borders often lack complexity and, therefore, fall short. Instead, the authors assess the complex interplay of elements and dimensions of borders and show how this gives rise to instances of disorder/order and how such disorder/order becomes socially and spatially effective. They discuss principles of complexity-oriented border research, the significance of borders in emergent disorder/order formations and border demarcations as examples of social disorder/order in European border regions, the EU's and US' migration systems, and virtual realities. This book makes an important contribution to the emerging complexity shift in current border studies.With contributions byFalk Bretschneider | Cécile Chamayou-Kuhn | Ulla Connor | Norbert Cyrus | Astrid M.
