This shift has ambiguous Will it bring a more sustainable, less ecologically disruptive form of production, or escalating levels of unemployment? Questions of personal engagement are What to be apprehensive about? Where are the possibilities for action in a context where such possibilities are being limited? This book will appeal to students and social scientists with an interest in technology, globalization and the changing economy. It is accessibly written and relevant to researchers and policy makers within the public and private sectors as well as an academic readership.
