Medical examiners are often first to recognize unusual occurrences of fatal infectious diseases. Recognition of these deaths allows public health officials to institute appropriate public health measures. Therefore, we developed a simple method of identifying and tracking infectious disease deaths in a statewide medical examiner's office. One-page infectious disease forms were completed for 1566/1949 autopsies (80%) performed at the New Mexico Office of the Medical Investigator in 2004. In 241 cases one infectious disease was identified at autopsy and 58 cases had two infectious diseases. Fourteen of the infectious-diseases caused deaths involved diseases that are notifiable conditions in New Mexico. Pneumonia was the most commonly reported infectious process (47 deaths) followed by sepsis (25 deaths). Tracking infectious disease deaths highlighted the importance of recognizing these deaths, although hand-written entries were unstandardized. Preferably, a tracking system would be built into electronic databases at medical examiner and coroner's offices, expediting the identification of these diseases and contact of public health agencies. 相似文献

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

Intercommunal, socio-economic, and political relations in the North Caucasus have historically revolved around access to this mountain region’s prized pasturage and scarce farmland. Given the centrality of the land question in the North Caucasus, it is unsurprising that historiography on land relations in the region has been highly politicized. This article examines how indigenous writing on the history of land relations in the central Caucasus – a region inhabited by today’s Kabardians, Balkars, Ossetians, Ingushes, and Karachais, and dominated by the princely confederation of Kabarda before the tsarist conquest – has been subject to wide revision in response to changes in local and national political dynamics and the emergence of ethnicized identity politics. In the late-imperial and early Soviet periods, Karachai, Balkar, and Ossetian elites-cum-historians, writing for an audience of imperial policy-makers, crafted histories to influence state policies toward land reform. By the 1930s, historians from the region tailored their histories of land relations to the prerogatives of Soviet nationality policies. The ideas contained in these histories impacted the construction of national identities in the Soviet period. Post-Soviet Karachai and Balkar intellectuals, seeking to establish new post-colonial national histories for their peoples, have reinterpreted the history of land relations in order to depict their ancestors as independent of Kabarda’s land-based dominance. This revisionism is part of the struggle of the Karachais and Balkars against their historiographical erasure, which was a product of the exclusion of the Karachais and Balkars from the family of Soviet nations during their deportation and exile to Central Asia from 1944 to 1957 and their subsequent political and cultural marginalization. 相似文献

AbstractThe Internet has been widely acknowledged as facilitating many forms of youth offending. Existing research has identified important drivers of young people’s involvement in online crime, yet this has overwhelmingly relied on school or college samples. As such, it tells us little about those young people that have left the formal education system—a group who are more likely perpetrators of juvenile crime more generally. Focusing on young people’s involvement in online piracy offenses, our analysis draws on data from a nationally representative survey of England and Wales to better understand the dynamics of involvement in online crime across the population. We assess the potential overlaps between online and offline offending, the role of differential association and deviancy neutralization techniques in shaping offending behavior, as well as the protective effect of strong family support networks in reducing involvement in piracy. We find that illegal downloaders tend to be young, male, and have a higher number of delinquent friends. We also find that many of these offenders do not confine their offending to online spaces, with involvement in offline property offenses also high among this group. 相似文献

This article reports the results of and conclusions from a survey of Northern NGOs conducted during 1998 and 1999 for the purposes of testing generalised criticisms of Northern NGO advocacy and providing benchmarks for further research on the policy impact of the Washington Advocacy office of Oxfam International. Based on the survey findings, the author challenges Northern NGOs to evaluate more thoroughly their advocacy so that they may effectively demonstrate their advocacy achievements and, by so doing, confidently invest a greater proportion of resources into advocacy programmes which effectively contribute to their goals of reducing poverty. 相似文献

The paper describes and discusses the Indian peasant uprising which took place in the Puna (high tableland) of Jujuy Province in Northern Argentina between 1872 and 1875. The origins of the revolt are to be found principally in the land tenure system, and specifically in problems associated with the historical evolution of the colonial encomienda system. The role of ‘outside’ political forces in the uprising is discussed and evaluated, but it is argued that the Indians’ demands for the return of their communal lands was the fundamental issue. In this respect it is suggested that the revolt should be examined within the wider context of Indian revolts and agrarian unrest which affected various parts of the Andean Highlands during the last thirty years of the nineteenth century. 相似文献
