Research Summary: In California, incarceration in the state prison system is in part organized by security level. The higher the security level, the more restrictive the setting. Upon arrival at a reception center, new inmates are scored within a classification system that is used to determine the appropriate level of security. In this paper, we report on the development and testing of a new inmate classification scoring system. Over 20,000 inmates took part in a randomized experiment in which half were assigned to their housing using the existing scoring system and half were assigned to their housing using the new scoring system. There were two key outcomes: (1) potential mismatches between the number of inmates assigned to different security levels and the available beds and (2) reports of inmate misconduct. Policy Implications: We conclude there to be some potential crowding problems, but that the new scoring system is much better than the old scoring system in sorting inmates by the likelihood of misconduct. We also conclude that some predictors popular in the past are no longer effective (e.g., marital status), while some new predictors are extremely powerful (e.g., gang activity), and that one can build in a number of mandatory housing placements (e.g., for sex offenders) and not degrade the overall effectiveness of the new classification system. Finally, the new classification system is shown to be more user‐friendly than the existing classification system and well received by the staff responsible for implementing it.  相似文献

Abstract This paper explores certain of the general problems associated with maintaining research access in police organizations. Among the problems researchers are likely to encounter are difficulties in communicating and winning the acceptance of street-level patrol officers, problems in developing a mutually acceptable field role, and threats of premature termination. The solutions suggested include specific and repeated efforts to inform patrol-level officers of the research, emphasis of the occupational features of the traditional participant-as-observer role, and making specific plans to deal with attempts at premature termination.  相似文献

This paper uses data from middle class suburban high school students to examine the relationship between broken homes and self-reported delinquency. Only small effects of family structure on delinquent acts are discovered. Methodological and theoretical problems which are common to research on broken homes are outlined and the contradictions between our results and those of other researchers are then analyzed from the alternative explanations of specification and spuriousness.  相似文献
