The collaboration that led to this book began, as has become commonplace, with an email exchange across many time zones and bilateral comments on current research. We owe many thanks to David Baker for encouraging that initial communication six years ago, for inviting us to present our research in a special session at the centennial American Sociological Association (ASA) meeting in Philadelphia in 2005, and for generally supporting our work on the (comparative) institutional analysis of special education. We presented further iterations at the ASA meetings in 2007 in New York and in 2009 in San Francisco, and we would like to offer our thanks to the participants for their helpful comments. And we owe a special thanks to Doug Judge, whose research collaboration into the case law for juvenile corrections was always strengthened by his theoretical contributions.
For the funding of research stays for the first author in Berlin and London and for workshops held in Berlin and San Francisco, we gratefully acknowledge the financial support of the German-American Academic Relations Foundation (Stiftung Deutsch-Amerikanische Wissenschaftsbeziehungen im Stifterverband für die Deutsche Wissenschaft). We also thank the German Academic Exchange Service (DAAD) and the Volkswagen Foundation for
