South Africa currently has a high homicide rate. This results in a large number of unidentified bodies being recovered each year, many of which are referred to the forensic examiner. This situation has resulted in considerable growth of forensic anthropological research devoted to devising standards for specific application in South African medico-legal investigations. The standards suitable for Black South Africans now encompass a wide variety of skeletal elements (e.g. cranium, humerus, pelvis, femur, patella, talus, calcaneus), each with differing degrees of accuracy. Apart from a preliminary investigation of the Zulu local population, however, we note that there appears to be no established metric mandible discriminant function standards for sex determination in this population. The purpose of the present study is to undertake a comprehensive analysis of sexual dimorphism in the mandible of Black South Africans, incorporating individuals from a selection of the larger local population groupings; the primary aim is to produce a series of metrical standards for the determination of sex. The sample analyzed comprises 225 non-pathological mandibles of Black South African individuals drawn from the R.A. Dart Collection. Nine linear measurements, obtained from mathematically transformed three-dimensional landmark data, are analyzed using basic univariate statistics and discriminant function analyses. All of the measurements examined are found to be sexually dimorphic; the dimensions of the ramus and corpus lengths are most dimorphic. The sex classification accuracy of the discriminant functions ranged from 70.7 to 77.3% for the univariate method, 81.8% for the stepwise method, and 63.6 to 84% for the direct method. We conclude that the mandible is a very useful element for sex determination in this population. 相似文献

Campaign finance contributions may influence policy by affecting elections or influencing the choices of politicians once in office. To study the trade‐offs between these two paths to influence, we use a game in which contributions may affect electoral outcomes and signal policy‐relevant information to politicians. In the model, a campaign donor and two politicians each possess private information correlated with a policy‐relevant state of the world. The donor may allocate his or her budget to either an ally candidate who has relatively similar preferences or a moderate candidate whose preferences are relatively divergent from the donor's preferred policy. Contributions that increase the likelihood of the moderate being elected can signal good news about the donor's preferred policy and influence the moderate's policy choice. However, when the electoral effect of contributions is too small to demand sufficiently high costs to deter imitation by groups with negative information, this informational effect breaks down. 相似文献

Although a considerable amount of thoughtful scholarly research on state crime has been conducted and published, researchers have failed to assemble a comprehensive model of the process and reactions that begin after state crime has occurred and been detected. This article outlines a heuristic model that presents the major political actors that participate in this process and the relationships that can develop among them. In order to create the model, research that has been conducted on state crime is reviewed and integrated, difficulties with this work are analyzed, and recommendations about future research that can be conducted using the model are made. 相似文献

Accountability is a vogue word. It has been around for a while now, but does not seem to be going out of fashion. Probably that is because the word reflects and reinforces a value system in relation to government and administration which is solid and good, not just a passing fad. If that is right, then the only difficulty with the notion of accountability is that it may be bandied round to such an extent as to become a mere slogan, a substitute for thought. 相似文献
