This paper addresses two neglected areas in the research on the relationship between family violence and violence outside the home: violence other than parent-child abuse and the effect of gender. Specifically, we consider both parental and sibling violence as independent variables, nonfamily violence as the dependent variable, and gender as the specification variable. The data were collected from a sample of 306 students in Introductory Sociology and Social Problems classes. The finding of particular importance is that the interaction between the gender of both the aggressor and the victim has a significant effect on the relationship between violence within the home and nonfamily violence. 相似文献

Comparison of a suspected biter's dental arches with the patterned injury of a bite mark is especially difficult when the bite occurs in an anatomic location with a small radius of curvature or with complex or compound curves. The authors present two case reports in which human skin was used as a template for the reproduction of a bite. In one case the victim's skin was used; in the other, the skin of a anatomically similar person was used. The use of inked dental casts, photography, and transparent overlays significantly reduced the errors common to analysis of bite marks in these highly curved areas. 相似文献

The absence of a thoroughly developed, working class critique of criminological theory has resulted in bias in the creation
of knowledge regarding crime and deviance. Much as feminist writings illuminated the unique problems related to gender, and
works by those discussing racial and ethnic minorities highlighted the special concerns related to race and ethnicity, a working
class perspective can expose the particular issues having to do with class. A brief discussion will be presented dealing with
the portrayal of working class people in the media, and the complicity of academia in allowing working class stereotypes to
persist. A sketch of a working class perspective will then be developed, and it will be used to critique fourteen of the major
criminological theories today in terms of their relative sensitivities and considerations of the class factor in crime and
justice issues. The final section places each of the fourteen theories on a continuum from those that do not consider the
working class experience at all to those that give the working class experience full consideration.

Although law enforcement agencies across the nation have assumed part of the responsibility in the fight against terrorism, significant confusion exists as to the role of local law enforcement. While some agencies have taken steps towards terrorism prevention, little data has been collected on which agencies have taken the greatest steps, how those agencies have changed, and how other agencies should direct their activity. This case study of law enforcement census data from a single state considered variations in terrorism preparedness and predictors of preparedness. Agency size, presence of funding, and other variables significantly predict levels of terrorism preparedness. Important policy implications such as the distribution of funding and which agencies should be working towards terrorism preparedness are discussed. 相似文献

In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane. 相似文献
