Has research made a difference to criminal justice practices and policies? Evidence-based crime policy is not just about rigorously generating a robust supply of rigorous research to find out "what works" in terms of justice interventions or "what explains" crime or offending. Evidence-based crime policy means that this supply should be attuned to the demand for research, and that research must be converted to meaningful forms and implemented with fidelity in order for practice to be receptive to science. But how does this actually happen?An important concept in the field of evidence-based crime policy is translational criminology, or how, why, whether, and under what conditions research is converted to, and used, in practice. This Springer Brief series on translational criminology brings to both the academe and criminal justice world examples of how research becomes practice and policy, and whether research has made an impact. Each brief is written by top scholars and/or practitioners in the field who describe specific examples of how a body of research became practice (or didn't) and the lessons learned from the endeavor.More information about this series at
