A nonrecursive model of the deterrent effect of police presence was formulated and tested for 26 cities. Victimization data were employed as measures of crime, unpublished FBI data on the number of police patrol units as the measure of levels of police presence, and data for 11 exogenous variables were derived from FBI and census reports. It was found that per capita, police are a positive function of rates of violent crime and that clearance rates are a positive function of police presence. However, some offenses that have traditionally been thought to be deterrable are not inversely related to clearance rates. The equations were re-estimated using official measures of crime and found to be more consistent with the deterrent hypothesis. It is suggested that official data may generate a spurious correlation. Finally, caution is suggested in consideration of alternative forms of police presence.  相似文献

Public hospitals on the brink: their problems and their options   总被引:1,自引:0,他引:1  
This article defines the differences among public community hospitals, and examines the problems faced by those that serve primarily the poor. The article analyzes the impacts of (1) the tradition of local fiscal responsibility, (2) third-party funding arrangements, (3) public hospitals' bases of political support, and (4) problems in governance and administration. Three broad policy options for public hospitals are considered in the light of these impacts.  相似文献

The routine production of a cast of a shoe-print taken in soil provides information other than shoe size and gait. Material adhering to the surface of the cast represents the preservation of the moment of footprint impression. The analysis of the interface between the cast and soil is therefore a potentially lucrative source of information for forensic reconstruction. These principles are demonstrated with reference to a murder case which took place in the English Midlands. The cast of a footprint provided evidence of a two-way transfer of material between the sole of a boot and the soil of a recently ploughed field. Lumps of soil, which had dried on a boot, were deposited on the field as the footprints were made. Pollen analysis of these lumps of soil indicated that the perpetrator of the imprint had been standing recently in a nearby stream. Fibre analysis together with physical and chemical characteristics of the soil suggested a provenance for contamination of this mud prior to deposition of the footprint. Carbon/nitrogen ratios of the water taken from the cast showed that distilled water had been used thus excluding the possibility of contamination of the boot-soil interface. It was possible to reconstruct three phases of previous activity of the wearer of the boot prior to leaving the footprint in the field after the murder had taken place. This analysis shows the power of integrating different independent techniques in the analysis of hitherto unrecognised forensic materials.  相似文献

Hate crimes are motivated by perpetrators' prejudice toward targets' group. To examine individuals' attitudes toward hate crime perpetrators and targets, participants responded to vignettes of court cases in which the victim's group membership was varied. Results showed that participants recommended more severe sentences for perpetrators when the targets of their crimes were not White males or White females and reported those crimes as more closely fitting the definition of "hate crime." These results show that participants consider penalty enhancements appropriate for hate crimes and that they do not consider crimes against women to be hate crimes, consistent with present hate crime legislation. These results have implications for the utility and support of hate crime legislation but may showcase the resistance to expanding the legislation to protect individuals of other groups, especially women.  相似文献
