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

This paper explores the capacity of alternative theoretical perspectives to explain the self-reported criminality of black and white young adult females. When criminal involvement is regressed on the theory operation-alizations separately by race, a key difference emerges: For white women, significant effects are clustered in the social-psychological theory groups (bonding, attitudes, and maturation), but for the black women the social-psychological variables have only scattered and inconsistent eflects. Instead, for black women structural indicators emerge as the important predictors of criminal involvement.  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

Retention of offender DNA samples serves an important quality assurance role for forensic DNA laboratories. Consistent with the principles of confidentiality underlying the establishment of the state and national DNA databases, safeguards are in place to protect the DNA samples from unauthorized use.  相似文献

The study presents a method for the demonstration of esophageal varices at autopsy by gastroesophageal phlebography. The veins visible on the radiographs were controlled and evaluated by studying the gross appearance of sections of the esophagus at the level of the varicose veins and by histologic examination of the sections. The phlebography was found to be useful in estimating the varicose and normal veins of the esophagus. The study indicates further that the degree of varicosity is not always proportional to the severity of cirrhosis of the liver, and there may be varicose esophageal veins in patients with liver or heart disorders without hepatic cirrhosis.  相似文献

This study examined the nature of police response to domestic violence incidents with a focus on the identification of areas of police intervention that female victims of domestic abuse find “most” helpful and “least” helpful. The first part of the study was based on the analysis of a random sample of incident reports of domestic abuse cases recorded in 2000 and 2001. These reports were examined to obtain information about the characteristics of domestic abuse victims and summary information about the incidents of domestic abuse offenses. The second stage of the research study involved a telephone survey conducted with a random sample of fifty female domestic abuse victims who called the police. The study examined female victims' perceptions of how the police responded to the domestic abuse incidents, how helpful or not so helpful victims found the police to be when they responded to their calls, and how their cases were handled by the legal system.  相似文献
