Contributors consider how system transitions come about and how they can be influenced by different actors, particularly by governments. They begin on the theoretical level, with a critical literature review and studies of socio-technological regimes, sustainability, and system innovations. They proceed to empirical examples of transitions in Switzerland and The Netherlands, then move to the effects of transition policy in sustaining mobility. They describe theories and practices for bounded socio-technical experiments. Two articles and the conclusion examine tools for transition policy and empirical illustrations, including managing experiments in energy and health care and in traffic and transport, with a final word on the lessons learned and remaining challenges. Each article contains its own references and the editors provide an index. Annotation ©2004 Book News, Inc., Portland, OR (booknews.com)
