Since 1998, over 5500 people have died while attempting to cross the U.S.–Mexico border without authorization. These deaths have primarily occured in the Arizona desert. Despite the high volume of deaths, little experimental work has been conducted on Sonoran Desert taphonomy. In this study, pig carcasses were used as proxies for human remains and placed in different depositional contexts (i.e., direct sunlight and shade) that replicate typical sites of migrant death. Decomposition was documented through daily site visits, motion-sensitive cameras and GIS mapping, while skeletal preservation was investigated through the collection of the remains and subsequent faunal analysis. Our results suggest that vultures and domestic dogs are underappreciated members of the Sonoran scavenging guild and may disperse skeletal remains and migrant possessions over 25 m from the site of death. The impact of scavengers and the desert environment on the decomposition process has significant implications for estimating death rates and identifying human remains along the Arizona/Mexico border.  相似文献

Nitrous oxide is an inflammable gas that gives no smell or taste. It has a history of abuse as long as its clinical use, and deaths, although rare, have been reported. We describe two cases of accidental deaths related to voluntary inhalation of nitrous oxide, both found dead with a gas mask covering the face. In an attempt to find an explanation to why the victims did not react properly to oncoming hypoxia, we performed experiments where a test person was allowed to breath in a closed system, with or without nitrous oxide added. Vital signs and gas concentrations as well as subjective symptoms were recorded. The experiments indicated that the explanation to the fact that neither of the descendents had reacted to oncoming hypoxia and hypercapnia was due to the inhalation of nitrous oxide. This study raises the question whether nitrous oxide really should be easily, commercially available.  相似文献

Excited delirium denotes a life-threatening medical condition characterized by the acute onset of agitated and violent behavior that often results in a sudden and unexplained death. Cocaine-induced excited delirium refers to fatal cocaine intoxication with the following symptoms occurring sequentially: hyperthermia, delirium with agitation, respiratory arrest, and death. We present a case of cocaine-induced excited delirium in a cocaine “body packer” or a “mule”, specifically an individual who attempts to smuggle cocaine within the body. Investigators at the scene initially suspected homicide due to the victim's sharp and blunt force injuries. Three rubber packets containing cocaine were removed from the victim's rectum. Blood toxicological analysis revealed an alcohol concentration of 0.016 g/100 and cocaine >1 mg/L. The forensic pathologist should consider cocaine-induced excited delirium when an individual exhibits aggressive behavior, unexpected strength, and resistance to pain who dies suddenly. Further analysis should be performed during the scene investigation and autopsy for evidence of body packing.  相似文献

Historical and recent challenges to the practice of comparative forensic examination have created a driving force for the formation of objective methods for toolmark identification. In this study , fifty sequentially manufactured chisels were used to create impression toolmarks in lead (500 toolmarks total). An algorithm previously used to statistically separate known matching and nonmatching striated screwdriver marks and quasi-striated plier marks was used to evaluate the chisel marks. Impression toolmarks, a more complex form of toolmark, pose a more difficult test for the algorithm that was originally designed for striated toolmarks. Results show in this instance that the algorithm can separate matching and nonmatching impression marks, providing further validation of the assumption that toolmarks are identifiably unique.  相似文献

South Africa's political liberalisation and strengthening regional ties have engendered new patterns of immigration and urbanisation, resulting in South African migrants and non-nationals converging on the streets of previously ‘forbidden’ cities. Conflicts over space, services and livelihoods are emerging as these groups meet and compete. To settle these disputes, South African citizens and politicians regularly rely on nativist discourses that make one's rights to the city contingent on one's national origins. Efforts to exclude foreigners are in turn encouraging and legitimising new forms of bias, administrative discrimination and anti-foreigner policing. Bolstered by official sanction, these are creating urban ‘zones of exception’, areas in which the state authorises its agents to work outside the law. Although popular among South Africans, the extra-legal harassment, detention and deportation of non-nationals has helped entrench new economies of corruption and violence that jeopardise the rights and welfare of all urban residents. While rooted in the dynamics of post-apartheid South Africa, these findings resonate with global trends in which quests to assert sovereignty through immigration controls are resulting in actions that undermine the legitimacy and founding principles of the liberal states that undertake them.  相似文献

The combined force of the 2012 coup in Bamako and the rebellion in the north entailed an unmasking of Mali. What had been presented as a showcase of democracy, good governance, and peace and reconciliation proved to be a facade for institutional weakness and mismanagement. The collusion between regional and national ‘big man’ interests that the crisis revealed showed little if any respect for human security and development. This article will analyse the causes of the crisis and the strategies of key actors, including the Islamist rebels. The consequences of and responses to the conflict will also be addressed before the article ends with some tentative conclusions concerning the future stability of Mali and the Sahel region. The article is based on the authors’ long engagement with Mali, spanning more than a decade, but the most recent material presented is based on a series of in-depth interviews conducted there in February and March 2013.  相似文献

This study investigates how an institutional exogenous change interacts with professional norms in relation to behavior in public organizations. We test how a new grading scale introduced in 2007 changed grade point averages and pass rates at two university departments. Data consist of register data on grading between 2004 and 2010. We find that the new grading scale both increased grade point averages and pass rates and halted the negative time trend in these variables. These effects are even greater for exams with an external examiner. The main conclusion is that grading systems affect grading both immediately and over time.  相似文献

This study examines the effect of fiscal decentralization between states and their local governments on the financial condition of municipal governments. There are strong theoretical arguments on both sides of the federalism debate about the benefits for and against decentralization. Most of the research in this area investigates economic and social welfare consequences of fiscal decentralization. There is limited research, however, on the effects of fiscal decentralization on the financial health of local governments. Using data from the nation’s 150 largest cities, this study finds that intrastate fiscal decentralization results in weaker financial condition for municipalities in those states.  相似文献

Abstract

China, once seen as a threat by the states of South Asia, is now viewed correctly as an alternative development opportunity. The unprecedented success of the Chinese development model places it as an obvious alternative to that offered by India—or indeed by the Western model of development—but what implications does this have for the middle and small powers that surround India, and indeed for India and the Western developed world? The fundamental rationale for China's relations with South Asia has changed radically, but the Sino-centric nature of Chinese foreign policy remains. Uniquely, for India's neighbours, but also for the global political economy as a whole, Chinese economic power raises political issues of human security, economic interdependence, and the relationship between physical infrastructure and the benefits of global public goods. The Chinese necessity to tranship through South Asia is identified as a complex new reality for the great power.  相似文献
