This article assesses the effects of one jurisdiction's attempt to control its lockup population through creation of a separate processing center designed to expedite initial processing of individuals charged with misdemeanors and minor felonies. In the new center, cases were screened and initial hearings held around-the-clock, seven days per week. “Before” and “after” samples of arrestees are compared on prosecutorial screening time, time to court, and time in custody. The results show significant reductions in case screening and length of time to initial court hearing. Individuals released on recognizance and those with no charges filed spent significantly less time in custody and saved considerable bed space for the jurisdiction. Individuals with bond set experienced no reductions in length of custody. Collateral consequences of the new facility included improved procedural justice, expanded detention capacity in the county, and an end to part of the federal litigation.  相似文献

This study examined crime and violence against abortion clinics, testing elements of several theories that may help explain the variation of such attacks. The study theoretically and methodologically improved upon the prior research on abortion-related crime and violence. Theoretically, it investigated previously unexamined hypotheses from the social movement literature that may be relevant to this type of behavior. Methodologically, it used more careful measures for several variables, employed unique and heretofore ignored data bases, and examined hundreds of criminal acts across several types of crime (e.g., violence, vandalism, and harassment) directed at abortion clinics. Employing robust logistic regression and correcting for clustering of clinics by state, the study investigated the cross-sectional effects of state-level cultural and structural characteristics on anti-abortion crimes against clinics and staff. Results indicated that some crimes against clinics are more likely in areas where female empowerment is weaker, female victimization is more tolerated, and the anti-abortion movement has failed to reduce abortions.  相似文献

This paper aims to review randomized experiments in criminology with offending outcomes and reasonably large numbers that were published between 1982 and 2004. A total of 83 experiments are summarized, compared with only 35 published between 1957 and 1981: 12 on policing, 13 on prevention, 14 on corrections, 22 on courts, and 22 on community interventions. Randomized experiments are still relatively uncommon, but there have been more large-scale multi-site experiments and replication programs. There have also been several experiments in which 100 or more places were randomly assigned. Relatively few experiments (only 10 out of 83) were conducted outside the United States. Meta-analyses suggest that prevention methods, correctional therapy, batterer programs, drug courts, juvenile restitution and deterrent policing were effective in reducing offending, while Scared Straight and boot camp programs caused a significant increase in offending.  相似文献

The study outlined in this article addressed a key limitation of prior research on the punishment of juveniles transferred to adult court by employing propensity score matching techniques to create more comparable samples of juvenile and young adult offenders. Using recent data from the Maryland State Commission on Criminal Sentencing Policy, it tested competing theoretical propositions about the salience of juvenile status in adult court. Findings indicate that even after rigorous statistical matching procedures, juvenile offenders are punished more severely than their young adult counterparts. We found no evidence that this “juvenile penalty” is exacerbated by an offender's race or gender, but it does vary starkly across offense type and mode of transfer, being driven primarily by drug crimes and discretionary waivers. The import of these findings is discussed as they relate to the future of juvenile justice policy regarding the continued use of juvenile transfer to adult court.  相似文献

Jail and prison populations in the United States have continued to grow unabated during the past two decades but crime rates have not declined. Partly in response to the pressures caused by burgeoning correctional populations, the use of alternatives to incarceration has expanded. An ongoing debate centers on the effectiveness of these alternatives. Many criminal justice professionals and some researchers question whether such alternatives seriously restrict the criminal justice system 's ability to incapacitate the active offender. This study deals specifically with two alternatives to incarceration: probation and parole. We examine offender recidivism for a sample of probationers and parolees active in New Orleans, Louisiana, and offer a new approach to addressing the effectiveness issue. Past research has evaluated the effectiveness of alternatives by examining failure rates of diverted offenders. High failure rates, we argue, do not necessarily imply a significant loss of the incapacitative effects of imprisonment. We suggest that a more appropriate measure of the loss of incapacitative effect is the proportion of all offenses committed by persons on probation or parole. Our results suggest that such losses are surprisingly low. The policy implications of our findings are discussed.  相似文献

A review of the available literature does not reveal a plausible explanation as to why the incisal edges of maxillary anterior teeth do not always mark clearly. Generally, the mandibular incisal edges do mark with some consistency. This paper demonstrates through test bites on skin that the answer lies in the position of the mandible.  相似文献
