Although the topic of recidivism invariably elicits much interest, there appears to be considerable conflict and uncertainty as to even crude estimates of the recidivism rate for persons released from prison. The purpose of this research was to examine the extent to which this apparent confusion may be explained by different methodological choices of criterion measure or length of follow-up. Through the cooperation of the Federal Bureau of Investigation, rap sheet follow-up information for a six-year period was obtained for a relatively large random sample of federal prisoners released in 1970. This data enabled calculation of recidivism rates using various criterion measures and follow-up periods applied to the same sample. The effect of varying these definitions on the recidivism rate obtained can then be directly observed. 相似文献

A large literature points to the abominable condition of American jails. Comparison of national surveys of jail conditions conducted in 1972 and 1978 indicates that what little improvement has occurred is minimal compared to remaining problems. A number of factors have prevented state-set standards from achieving widespread improvement in local jail conditions: high costs, local autonomy and lack of credible threats for forcing compliance. The failure of New York State to implement adequate health standards illustrates the limitations of the standards approach. Other approaches, such as strategies for replacing local jails with regional facilities, deserve the attention of policy researchers. 相似文献

The technique of isoelectric focusing in ultra-thin polyacrylamide gels as a method of typing human red cell phosphoglucomutase (PGM1) has been studied. Typing was possible without the samples attaining true equilibrium focusing conditions. The isozyme patterns so obtained were clearly defined and free from distortion. The importance of assessing relative band intensities when interpreting the isozyme patterns is discussed. Our experience of using the technique to analyse casework material is described. 相似文献

Policy scientists can make important contributions to the study of policy distribution, a question that is likely to be among the most crucial national issues to be discussed throughout this decade. One aspect of this question that has been neglected is the theoretical assumption associated with public choice theory that politicians, once elected, will reward their supporters through the distribution of policy benefits. However, empirical research indicates that policy benefits seldom are distributed in this way. Instead, politicians follow the principle of universalism. In league with bureaucracies and policy communities, politicians define need and then ask bureaucracies to allocate benefits. This makes politicians roles as distributors of policy very different than simplistic models suggest. 相似文献
