The other two are schoolmasters working as Assistantsat the School of Oriental and African Studies. For technicalreasons, the orthography is not quite complete.  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

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
