Presents the results of spectrophotometric and histologic examinations of subdural bleedings, meninges and brain matter in the acute period of a lethal craniocerebral injury. Discusses the possible use of a complex of histologic and biochemical studies in determination of the period elapsed since the injury.  相似文献

This article reports the results of a study of the antecedents of long-term success in community mediation. Seventy-three mediation sessions were recorded and content analyzed. The participants were interviewed at two points: immediately after mediation and 4 to 8 months later. No relationship was found between the quality of the agreements—i.e., the extent to which they solved immediate problems- and long-term success as measured by compliance, improved relations between the parties, and the absence of new problems. On the other hand, joint problem solving by the disputants was related to complainant perceptions of improved relations with the other party. Also respondent perceptions that the mediation had been fair and that all the problems had come out were related to all aspects of long-term success in the eyes of the complainant. The latter results support a procedural justice analysis of mediation and underline the importance of mediator attention to the respondent.  相似文献

How partner violence is transferred across generations is relatively unexplored. This paper proposes that anger expression style (constructive, destructive direct, destructive indirect) mediates the relationship between exposure to family violence and dating violence perpetration by adolescents. Data are from 1,965 completed self-administered questionnaires given to eighth- and ninth-grade students in a primarily rural county in North Carolina in 1994. Results varied by gender and type of exposure to family violence. For females, destructive direct and destructive indirect anger expression styles mediated the relationship between experiencing family violence and dating violence perpetration. For males, this relationship was mediated primarily by destructive direct anger expression style. The association between witnessing family violence and dating violence perpetration for females was mediated by destructive direct anger expression style only. Witnessing family violence was not associated with dating violence perpetration for males, and therefore could not be mediated. This study suggests that adolescents exposed to family violence learn anger expression styles that put them at risk of being perpetrators of dating violence. Further research is needed to identify other mediators that explain how partner violence is transferred across generations.  相似文献

Abstract.  The four theses of this paper are: (1) that an appropriate organizational form is used to design, define, and organize a functional unit of a legal system, (2) that the functional units of a legal system, contrary to the emphasis in Hart and Kelsen, consist of far more than rules, and include institutions, interpretive and other methodologies, sanctions and remedies, and more, (3) that frontal and systematic study of the forms of these units is a major avenue for advancing understanding of them as duly organized wholes, and, (4) that such study reveals that much credit is due these forms, along with complementary material or other components of the units, for values realized through law.  相似文献

The present study drew on four competing theoretical perspectives to examine the relationship between family structure and juvenile delinquency. Using data from the Add Health Study, the authors examined nonserious and serious delinquent behavior across youth from different types of households and also considered how the association between family structure and delinquency might be conditioned by family processes and economic factors. Results from negative binomial regression analyses indicated that, in general, type of household was not a significant predictor of nonserious or serious delinquency. Rather, maternal attachment emerged as the most important determinant of delinquent behavior among youth from all family types. The results are discussed within the context of Hirschi's original interpretation of social control theory and future directions for research are suggested.  相似文献
