Abstract:  Complete recognition and documentation of injury pattern is crucial in the diagnosis of child abuse. Skeletal fractures regarded as highly specific to nonaccidental injury in infants include posterior rib, scapular, metaphyseal, and spinous process fractures. These injuries are often occult, especially when acute, to standard radiologic and autopsy procedures. The presented autopsy technique requires incising and reflecting skeletal muscles to expose the bones and costal osseous joints in situ , increasing the opportunity to recognize skeletal injury. Fractured or atypical appearing bones are removed and processed for complete evaluation. The bones are processed by macerating the soft tissue in a water soap bath at an elevated temperature. To aid in reconstruction of the decedent, long bones are replaced with wooden dowels and the chest cavity is packed with the organ bag. The technique is invasive and recommended for cases in which the pathologist has reasonable suspicion of acute or remote trauma.  相似文献

Speed Kills     
Over the past two decades, a misguided, militaristic war on drugs has been waged through a variety of means, including drug interdiction programs on the streets and highways of the United States, and high-profile campaigns in the United States media designed to construct drug use as a dangerous social problem. Yet during this same period, a far more deadly social problem - the death of some 40,000 people a year in automobile accidents along these same streets and highways — has largely been excluded from public consciousness and public debate. Recently, a convergence of circumstances in New Mexico made visible this imbalance in public awareness and public policy, and perhaps even began to remedy it. The roadside shrines that decorate the highways of New Mexico and other states likewise serve this purpose, encoding the collective tragedy of automotive death in the cultural landscape. In their tragic beauty and ongoing accumulation, these shrines challenge critical criminologists to find a new focus, a new everyday criminology of the automobile that can expand the existing criminology of automotive corporate crime. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Unemployment Insurance (UI) benefits were a central part of the social safety net during the COVID-19 recession. UI benefits, however, are severely understated in surveys. Using administrative tax data, we find that over half of UI benefits were missed in major survey data, with a greater understatement among low-income workers. As a result, 2020 official poverty rates were overstated by about 2 percentage points, and corrected poverty reached a six-decade low. We provide data to correct underreporting in surveys and show that, compared to UI benefits, the UI exclusion tax expenditure was less targeted at low incomes.  相似文献

On the basis of extensive on-site interviews and documentary sources, the author interprets the dynamics of the collapse of the Soviet Union by analyzing the cascade of sovereignty declarations issued by republics of the USSR as well as by autonomous republics and other subunits of the Russian republic, in 1990-1991. Interrelationships among the declarations, and other putative causes of their content and timing, are explored. A case study of Tatarstan is provided. The study also analyzes the impact of the process on subsequent Russian approaches to federalism.  相似文献

Abstract:  The city of Quito, Ecuador, began working in 2000 to protect the ecologically fragile watershed area for its drinking water. In order to protect the Papallacta watershed, the independent Fund for the Conservation of Watersheds (FONAG) was launched to finance and manage economically sound sustainability projects in the area. FONAG is funded in part through start up grants from several organisations and a 1 per cent fee on all Quito water bills, but it has been unable to build an endowment sizeable enough to begin implementing conservation projects. We measure perceptions of the fund among Quito's university–based residents in two settings and evaluate the quality of the fund's proposed communication campaign based on existing communication theory. Further, we propose an adapted environmental education model based on a synthesis of existing theory and the empirical findings from our examination of the FONAG example. The Papallacta case study illuminates the potential strengths and weaknesses of the cultural ecology and political will of this type of collaborative sustainability project for addressing water problems in a developing country in a mountainous setting, centred around the themes of water conservation and sustainable development.  相似文献

Abstract: The merit principle is the primary means of restraining or avoiding political influence in civil service employment. It has received a good deal of attention at the national level of government but much less so at the provincial level. This article is designed to provide an assessment for Atlantic Canada. The author reviews the background in Britain and Canada and, after identifying the main elements of the principle, as developed at the national level of government in Canada, deals separately with each of the four Atlantic governments. He concludes that the merit principle has had its ups and downs throughout the region and that its current status varies considerably from province to province. Sommaire: Dans le secteur de I'emploi de la Fonction publique, le principe de la selection selon le merite est le meilleur moyen le limiter l'influence de la politique, voire de l'éviter. Ce principe a fait l'objet de beaucoup d'attention au niveau du gouvernement fédéral, ce qui n'a pas été autant le cas au niveau provincial. Dans cet article, I'auteur Bvalue la situation B ce sujet dans les quatre provinces de l'Atlantique du Canada. Il commence par passer en revue les données en Grande-Bretagne et au Canada, puis met au jour les principaux aspects du principe, tel qu'il a étéélaboré au niveau du gouvernement fédéral, pour en arriver enfin à traiter séparément chaque gouvernement des provinces de l'Atlantique. En conclusion, l'auteur dit que le principe de la sélection selon le mérite a connu des hauts et des bas dans les quatre provinces et, qu'à l'heure actuelle, la situation varie beaucoup de l'une B l'autre.  相似文献
