In the current study the objective was to find to what extent a reliable determination of age at death is made possible by establishing the degree of aspartic acid racemization in the dentin of teeth. The results of the investigation of 46 teeth are in agreement with the values found by other authors. The method presented makes a reproducible and accurate estimation of age possible. We intend to elaborate and improve this promising method for determination of age at death. The relevant points are presented here. 相似文献

This paper investigates one of the perennial mysteries in the area of state and local finance, the provision of tax and other subsidies to business by federal, state and local governments in the face of solid evidence that such incentives do little to nothing to influence business location or job creation. The paper looks at the upsurge in such governmental aid in the last decade and considers whether this upsurge has occurred because such aid is more efficacious than it used to be or whether it has occurred for political reasons unrelated to its effectiveness. 相似文献

Two conditions must be met in order for a person to be rightly considered the victim of a crime. First, there must be the victim of some form of harm. Second, the harm in question was the direct result of an act in which the harmed individual did not knowingly consent to take part. What are the dynamics of consent and how important should consent be in defining and placing criminal responsibility in crimes where women are sexually victimized? Finally, how does the conceptualization of victimization change when viewed from liberal and radical feminist perspectives? 相似文献

A decade of divorce mediation research has focused on outcomes such as settlement rates, cost efficiency, client satisfaction, effect on levels of conflict and cooperation, psychological adjustment, and compliance. Despite methodological problems limiting generalizations, most studies report mildly favorable to very positive findings. Research on the mediation process and mediator behaviors has received very limited attention, and should be the focus of the next decade of research to elevate the mediation field to a more sophisticated, effective level of practice. 相似文献
