Management research has focused on a number of issues related to court management, notably habeas corpus, the adequacy of defense counsel representation, and the extent and causes of case delay. Law reform research has focused on the need for law reform and assessment of the effectiveness of law reform initiatives. Some examples of such research are in the areas of sentence alternatives designed to reduce prison overcrowding and the effectiveness and use of fines. Evaluation research has guided the development of sentencing guidelines, and research on factors in dangerousness has helped to identify correlations between drug use and crime.
