An ordnance-disposal expert was killed while disposing of a cache of explosives. The likely position of the body was reconstructed by modeling the explosion as an omnidirectional emission of particles from a model of the explosion site and noting the distribution of particles on a model of a human. The applications and limitations of this method in reconstructing the events and correlation with the injuries noted at autopsy are discussed. 相似文献

Ketosis occurs in ketoacidosis or malnourishment. When either is suspected in relation to a death, it may be important to analyze for ketosis at autopsy. We encountered a case where starvation was suspected in a deceased nursing home resident, where the body had been embalmed prior to autopsy. Gas chromatography (GC) was unable to separate acetone from formaldehyde, a component of embalming fluid. The Acetest is a simple test that can detect acetone and acetoacetate in body fluids. We validated the Acetest with GC on vitreous. The Acetest and GC were consistent except at very low levels of acetone or acetoacetate. The sensitivity of the Acetest for acetoacetate in vitreous was 10 mg/dL, consistent with early starvation. Significant interference from embalming fluid did not occur. The Acetest was negative in the described case. The Acetest is a simple and useful test for the detection of ketosis in embalmed autopsies. 相似文献

This article will examine the development and implementation of the new geography curriculum in secondary schools in Shanghai. Analysis of the processes and mechanisms which underlie curricular change in China reveals how embedded bureaucratic, social and cultural norms have profoundly influenced the degree to which reforms to the geography curriculum have achieved the desired results. The analysis begins with a detailed examination of the wider institutional hierarchies which initiated and managed curricular reforms in Shanghai. Interviews with teachers and extensive classroom observations, and a review of the new curriculum and geography textbooks are utilised to evaluate the practical outcomes of curricular change in Shanghai. The findings reveal a deep dichotomy between the intended goals of curricular reform, the processes of curriculum development and implementation, and an examination system which compels teachers to cling to traditional teaching methods of lecturing and rote learning. These findings are discussed in the context of the established educational hierarchies, the cultural politics of curricular reforms in Shanghai and the nature of geography teaching in China. A more balanced approach which addresses the provision of adequate resources and professional development for teachers, and which recognises the need for a fundamental restructuring of the examination system, is suggested. 相似文献

The policy of Australian governments, both Commonwealth, state and territory, toward those organisations that comprise a third sector of the organised economy is patchy and piecemeal. Absent is any recognition that they constitute a distinct sector; absent too is any recognition of their contribution to economy, society and politics. Such a situation is not inevitable. After identifying some of the gaps and contradictions in Australian policy toward the third sector, this article outlines the many policy initiatives to encourage the third sector or social economy (in European Union terms) taken by the Blair government in the United Kingdom. Given that there is a good deal of policy borrowing between Australia and the United Kingdom, the stark contrast between the two countries in this policy field is puzzling. This article concludes by identifying four developments that led to this policy explosion in the United Kingdom and finds them largely missing in Australia. This leads to a conclusion that a similar range of policies are unlikely to develop here. 相似文献

Can bureaucracies respond to threats marked by both potentially high costs and fundamental uncertainty? Standard guidelines such as maximizing expected value to the society over a period of time may be ineffective; yet, state action is often most demanded for such situations. I argue that the precautionary principle of reserved rationality helps explain the ability of bureaucracies to choose appropriate actions under uncertainty. Such bureaucracies are empowered when there is sufficient informal institutional support for their expertise and the bureaucracy has the discretion to take necessary precautions. I draw historical information from the case of Singapore's regulation of the formerly common pool resource of water catchment areas. This case reveals decision making when it is not clear that the expected-value criterion would support action, as well as the importance of political and institutional support for such action. 相似文献

Political commentators argue that the major political parties are in decline. This article sets out evidence for this view: minor parties and independents securing 20 percent of the vote at federal elections, declining strength of voters' party identification, and issue movements playing a large role in setting the political agenda. Possible causes for these trends range from the political, such as policy failure, undermining traditional constituencies, and ignoring public opinion, to sociological forces, such as postmaterialism, individualism and serious disaffection. However, the article argues Labor and the Coalition will be the dominant political players for the foreseeable future. In most lower houses, the electoral system favours the major parties which on balance is a good thing. The major parties have taken concerns of interest groups into account, while balancing these against majority opinion. They simplify choice for an electorate only moderately interested in politics, and can be held accountable in a way minor parties and independents cannot. 相似文献

This research reports on a public-opinion survey on intergovernmentaland border issues in Canada and the United States conductedin mid-April 2002. In the United States, there was an upsurgein public support for the federal government in 2002 over 2001,and a slight decline in public evaluations of state and localgovernments. Increased support for the federal government wasespecially notable among whites, Republicans, and respondentswith post-undergraduate education-groups that previously registeredlow support for the federal government. Canadians reported lesssatisfaction with all governments in their federal system, lowersupport for their federal government, and much more regionaland partisan division over intergovernmental issues. On internationalborder issues, Americans and Canadians generally agreed thata common border-security policy would be a good idea, thoughCanadians were slightly more likely than Americans to preferease of cross-border trade over improved border security. 相似文献

The relationship of residential setting (living with parents vs. living away from home while attending college) and gender with late adolescents' perceptions of their relationships with parents was examined. Four hundred four undergraduates students (mean age=20 years, 4 months) from two midwestern universities completed surveys. Two hundred four subjects lived with their parents and commuted to school, and 200 lived away at college. Controlling for student's age, parents' education, and financial and family considerations as factors in the choice of a college, living away was associated with greater independence, support, and mutual respect between parents and adolescents. In contrast, students who lived at home felt parents underestimated their maturity, and reported more conflict and avoidance in their relationships with parents. Regardless of residential setting, women reported more mutuality and support in their relationships with parents than men. The results suggest the importance of considering contextual issues during the transition to adulthood.This research was supported by a Campus Grant to the first author from the University of Michigan-Dearborn.Received Ph.D. in developmental psychology from the University of Michigan.
