Criminology has developed strong methodological tools over the past decades, establishing itself as a competitive and sophisticated social science. Despite and perhaps because of its emphasis on research design, methodology, and quantitative analysis, criminology has had few significant advances in theory. This is the first publication exclusively dedicated to the dissemination of original work on criminological theory. It encourages theory construction and validation in existing criminological publications, as well as furthering the free exchange of ideas, propositions, and postulates. This volume is dedicated to a pioneer in criminology, Donald Cressey, and is especially noteworthy for its comparative and international dimension.
