These four working papers present research designs for system-wide data analysis and productivity measurement for evaluation. The four papers, prepared by four working teams, are titled, "Performance Measurement and the Criminal Justice System," "A Conceptual Basis for Effectiveness Measurement of Law Enforcement Activities"' "Performance Measures for Evaluation of LEAA and CJS Programs;" and "A Program of Research on Performance Measurement and Evaluation for the Criminal Justice System." Concepts covered by the papers include total social cost associated with crime and crime control, a systematic approach to determine a methodology for the measurement of law enforcement effectiveness, system-level aggregate performance measures, analysis and interpretation of criminal justice statistics, and operational performance measures. An additional topic coverage is the use of evaluation as a technical tool for better measurement and resource allocation
This is the first book to explore the application of complexity theory to difficult practice issues in criminal justice and social work and brings together experts in this emerging field to address complexity theory from a range of perspectives, providing a detailed but accessible discussion of the key issues to whole systems approaches.
Approaches based around complexity theory are increasingly being used in the study of organisations and the delivery of services. This is the first book to explore the application of complexity theory to difficult practice issues in criminal justice and social work and is intended to stimulate debate. It brings together experts in this emerging field to address complexity theory from a range of perspectives (positivist, realist, and constructivist), providing a detailed but accessible discussion of the key issues to whole systems approaches. The chapters cover theory and research on the nature of complex adaptive systems, their application to key areas of service delivery and the efficacy and ethics of criminal justice and social work interventions. The book argues for the usefulness of applying complexity theory to address significant and intractable social problems and also challenges the reductionist approaches to solving those problems currently favoured by policy makers. It will be of interest to academics and postgraduate students in social work and criminal justice.
The use of simulation modeling in criminal justice dates back to the 1970s. Early models were developed to capture the realities of the criminal justice system, to identify what changes were needed, and how small changes would affect the overall picture. Significant time and effort were devoted to these projects and although they achieved some success, the complex nature of the criminal justice system and the difficulties associated with improving and maintaining the models prohibited wide spread adoption in the field. Some of the problems with early simulation projects were the lack of data to validate models, the lack of technical skills needed by staff to design and build the models, and the technical difficulties with software programming to transform models into computerized representations. As simulation modeling has becoming a more popular technique across many disciplines, and technology as well as the technical skills of researchers has improved, this book revisits the concept of simulation modeling with new applications for the criminal justice system. The wider availability of data has made for more opportunity to verify and validate models; computing software has become more available and easier to use; and the capacity for visualization and communication of models shows promise for the future of simulation in criminal justice. The time has come to examine the past, present, and future contributions of simulation modeling to the field of criminal justice. This work provides a central resource of information for the current state of simulation modeling, and overview of existing techniques and cases of success, and directions for future development. This work will be an important resource for researchers in criminal justice and related fields, as well as those studying policy-related topics.
"The present paper describes an on-going project within the Canadian criminal justice system for the development of a systems planning model, intended for use by planners, administrators, and line decision-makers. The model is intended to assist in estimating quantitatively the impact of proposed future changes to the system (both legislative and programmatic), and to serve as a better monitoring device for making accurate assessments about present activities in the Canadian criminal justice system"--Prelim.
This book offers Walters's latest evolution of criminal lifestyle theory. It introduces the concept of criminal thought content to illustrate how the potential interplay between what offenders think and their thought processes can greatly aid our understanding of both crime and criminals. In this new study on criminal behaviour, Walters calls for criminological theory to be placed within a broader scientific context, and provides us with several key models which embrace constructs from numerous important theories including: the general theory of crime, social cognitive and social learning theories, general strain theory, psychopathic personality theories of crime, and labelling theory. Another unique aspect of this work is that it places lifestyle theory within a larger scientific framework, namely, nonlinear dynamical systems theory or chaos. Seven principles from chaos theory are used to explain relationships and processes central to lifestyle theory and Walters uses this to draw conclusions on what affects criminal decision-making and desistance from crime. Highly original and innovative in scope, this book will be useful to practitioners and scholars of criminal justice alike, with chapters focussed on decision-making, assessment, and intervention.
This student-friendly introductory text describes the criminal justice process—outlining the decisions, practices, people, and issues involved. It provides a solid introduction to the mechanisms of the criminal justice system, with balanced coverage of the issues presented by each facet of the process, including a thorough review of practices and controversies in law enforcement, the criminal courts, and corrections.
