Abstract: Immature blow flies (Calliphoridae) are typically the first colonizers of cadavers. Identification of the early instars using traditional, morphology‐based keys is difficult because of their small size, similarity, and simplicity in external morphology. Information derived from molecular genetic data would augment the accurate identification of immature flies. Nine species of blow flies commonly found in southeastern Nebraska were used to examine the utility of molecular‐based keys. Polymerase chain reaction–restriction fragment length polymorphisms (PCR–RFLP) were investigated with 10 common, inexpensive, restriction enzymes from an amplicon of approximately 1500 bp spanning the mitochondrial cytochrome oxidase I gene. A simple molecular taxonomic key, comprising RFLP from the restriction enzymes HinfI and DraI, enabled the differentiation of all species used. Further development of PCR–RFLP, including more extensive and intensive examination of blow flies, would benefit forensic laboratories in the accurate identification of evidence consisting of immature blow flies.  相似文献

Product counterfeiting has received increased attention due to its economic and public health impact. Media framing of product counterfeiting shapes how the public and policymakers understand the problem. While there is a large body of literature examining crime and the media generally, empirical studies have yet to focus on the media construction of product counterfeiting. This study presents the results of a content analysis using a random sample of newspaper articles referencing product counterfeiting in the New York Times and the Wall Street Journal from 2000 to 2009. Articles were coded for common patterns in sources of information. While the results indicate the presence of a wide variety of themes, product types, and industries, government and business sources are overrepresented among the sources cited, leading to some level of consistency in the presentation of the impact of and appropriate responses to product counterfeiting. Implications for understanding how the public and policymakers understand product counterfeiting are discussed.  相似文献

Medical respite programs offer medical, nursing, and other care as well as accommodation for homeless persons discharged from acute hospital stays. They represent a community-based adaptation of urban health systems to the specific needs of homeless persons. This article examines whether post-hospital discharge to a homeless medical respite program was associated with a reduced chance of 90-day readmission compared to other disposition options. Adjusting for imbalances in patient characteristics using propensity scores, respite patients were the only group that was significantly less likely to be readmitted within 90 days compared to those released to Own Care. Respite programs merit attention as a potentially efficacious service for homeless persons leaving the hospital.  相似文献

Throughout the 1990s, corruption cases, policy failure and scandals tarnished Belgium's international reputation. In this article, we analyse the effect of federalism and political culture on corruption and policy failures and their impact on the likelihood of such occurrences becoming scandals. Survey material suggests that there are few differences between French- and Dutch-speakers in the perception and tolerance of corruption. We then list a number of variables that can explain corruption in Belgium and argue that the independent effect of federalism is very limited. Next we demonstrate that federalism has played a much more significant role in lowering the risk of policy failure, while at the same time creating a few new vulnerabilities. Finally, we argue that the regional political elites do not often engage in policy learning and frequently put forward federalism as the main solution to the avoidance of policy failure and scandal. In this sense, regional political elites do not seize the opportunity for policy experimentation and transfer that is generally seen as one of the main virtues of a federal system of government.  相似文献

At the limits of spatial governmentality: A message from the tip of Africa   总被引:1,自引:0,他引:1  
Urban studies scholars drawing on Foucault's analysis of governmentality have investigated how urban social orders are increasingly more concerned with the management of space rather than on the discipline of offenders or the punishment of offences (Merry, 2001). This paper examines the 'rationality' and efficacy of spatial governmentality in post-apartheid Cape Town, and shows how the city has increasingly become a 'fortress city' (Davis, 1990), much like cities such as Los Angeles, Sao Paolo and Rio de Janeiro. These 'global cities' are increasingly characterised by privatised security systems in middle class suburbs, shopping malls and gated communities (Caldeira, 1999). These spatial forms of governmentality draw on sophisticated security systems comprising razor wire and electrified walls, burglar alarms and safe rooms, as well as vicious guard dogs, neighbourhood watches, private security companies, and automated surveillance cameras. On the other side of the race and class divide are urban ghettoes characterised by growing poverty and everyday violence. These socio-spatial inequalities continue to be reproduced despite urban planning initiatives aimed at desegregating the apartheid city. Although the media and the middle classes highlight the dangers of crime and violence, they tend to ignore the structures of inequality that fuel the growth of crime syndicates and violent drug economies that are reproducing these urban governance crises. Given the diminished resources of the neo-liberal state, the policing of middle class residential and business districts is increasingly being 'outsourced' to private security companies. In working class neighbourhoods of Cape Town such as Manenberg, the state has attempted to re-establish governance by resorting to new forms of spatial governmentality. The paper draws attention to the limits of these attempts to assert state control through the management of space. Spatial governance in places like Manenberg will continue to be relatively ineffectual given existing levels of social inequality and racial polarization. Such processes are reproduced by massive unemployment and racialised poverty resulting from socio-spatial legacies of apartheid and Cape Town's shift from a manufacturing to a tourist, IT and financial services economy. Although this paper focuses on attempts at re-establishing governance in a crime and gangster-ridden working class neighbourhood of Cape Town, it addresses these issues in relation to city-wide shifts to new forms of spatial governmentality after apartheid.  相似文献

The marketplace of ideas within a mature democracy such as the United States is supposed to fairly reliably vet foreign policies through open, wide-ranging debate. It is widely recognized that the U.S. marketplace of ideas failed during the 2002-03 debate over going to war in Iraq. Examinations of this market failure have emphasized executive powers and public fear after 9/11 as the main reasons threat inflation succeeded; I show neither explains this case. The majority opposition was silenced throughout early 2002 and ultimately defeated in a struggle over the Iraq War Resolution by pressures to be patriotic. I contend that this silencing patriotism should not be considered ordinary patriotism for a democracy as it is anti-democratic. I discuss how two critical norms of behavior which silence debate of national security policies and cause deference to the executive branch on war powers became established as part of the militarized political culture that took root in the United States during the Cold War. Thus these norms, enforced by what I term to be militarized patriotism left over from the Cold War, silenced debate over Iraq and led to the failure of the marketplace of ideas.  相似文献
