In this exciting and topical collection, leading scholars discuss the implications of globalisation for the fields of comparative criminology and criminal justice. How far does it still make sense to distinguish nation states, for example in comparing prison rates? Is globalisation best treated as an inevitable trend or as an interactive process? How can globalisation's effects on space and borders be conceptualised? How does it help to create norms and exceptions? The editor, David Nelken, is a Distinguished Scholar of the American Sociological Association, a recipient of the Sellin-Glueck award of the American Society of Criminology, and an Academician of the Academy of Social Sciences, UK. He teaches a course on Comparative Criminal Justice as Visiting Professor in Criminology at Oxford University's Centre of Criminology.
