Much of the information we now have on crime, criminals, and the operation of the criminal justice system has come from the work of sociologists. Due not only to their careful attention to the formation and development of theoretical perspectives but also to their grounding in empirical research methodology, the role for social scientists in the analysis of crime and punishment would be a natural one. Applied sociology is defined by Angell (1967:725) as sociology that 'is not an end in itself, but (that) becomes a means to some other end.' He provides a neat breakdown into three principal subroles that may be assumed by the applied sociologist: consultant, practitioner, researcher. The sociologist-as-consultant is an outside expert, often in gathering and explaining data for his client, an agency or institution. The sociologist-as-practitioner is a person schooled in sociology but employed to work directly in the field of human services, such as warden of a prison. The researcher in a practical setting works for some prison or organization that desires knowledge for some reason of their own. Here, we will be concerned, in one way or another, with all three dimensions. (Publisher abstract)
