England and France have developed distinct treatment systems to address the shock of a substantial increase in over‐indebted individuals since the mid‐1980s. In France, Over‐Indebtedness Commissions, with the Bank of France playing a central role in their management, now dominate the system. A more fragmented system of private and public providers of remedies developed in England, with innovation driven by private actors modifying existing commercial procedures and increased access to bankruptcy relief a side‐effect of government promotion of entrepreneurialism. This article explains the differences between these countries in terms of the influence of interest groups, including state actors, and ideologies. Historical contingency also plays a role. The distinct responses were not hard‐wired to legal origins and the article argues that analysis of the interaction of interest groups, state actors and ideology in shaping institutions, which in turn structure future change, provides a productive approach for future comparative research in this area.  相似文献

Abstract: The diagnosis of early myocardial infarction (MI) after death, especially in the first few hours (c. 6 h) after the onset of MI, poses a challenge to the forensic pathologists. During this time, the damaged myocardium does not show grossly identifiable morphological changes and may not be recognized even with routine histological microscopic examination. However, the infarcted cardiac tissue releases certain chemicals that can be detected microscopically, two of these being cardiac troponin‐I (CT‐I) and complement C9 (C9). This study utilizes the importance of these two biomarkers immunohistochemically in an attempt to identify this early phase of MI. This study reveals that the early phase of MI of <6 h duration may be detected through immunohistochemical staining with CT‐I and C9. The ischemic/infarcted cardiac myofibers in the <6 h group display reduced/absent CT‐I staining as well as positive C9 staining.  相似文献

The brain distribution of phenothiazine antipsychotics in 22 confirmed schizophrenic and 11 control subjects were collected at autopsy. Specimens were homogenized, extracted with n-butyl chloride, and analyzed via liquid chromatography-mass spectrometry, using atmospheric pressure electrospray ionization operating in the positive mode. Drug concentrations normalized for those observed in cerebellum showed three distinct patterns of distribution corresponding to different structural features of each type of phenothiazine. Those drugs with high affinity for dopamine receptors were detected in the highest concentrations in regions with high concentrations of such receptors. However, those associated with relatively lower dopaminergic activity were found in the highest concentration in the occipital cortex, a region with a relatively low concentration of dopamine receptors. The regional brain distribution of thioridazine and its metabolites was concentration dependent. These results have implications for determining the role of these drugs in the sudden and unexpected deaths of schizophrenics.  相似文献

As predicted by Duverger's Law, the UK has had two-party competition for long periods in most electoral districts. However, there are different patterns of two-party competition in different districts and more than two effective parties in the Commons. Since 1874, parliament has always contained parties wishing to modify the Union and contesting seats only outside England. By calculating the Penrose power index for all parties in the House of Commons for all general elections since 1874, we identify when such parties were pivotal. We explain various legislative changes (for example the Crofters Act 1886, the first three Irish Home Rule Bills, the Parliament Act 1911) and non-changes (for example the failure to enact female suffrage before 1914) by reference to the Penrose index scores. The scores also explain how and why policy towards Scotland, Wales and Northern Ireland changed and did not change in the 1970s.  相似文献

In the era of Daubert and other judicial rulings pertaining to the acceptability of forensic evidence, it is increasingly important that experts are able to testify that their methods have been scientifically tested and that error rates and other factors relating to reliability have been published. The purpose of this study was to determine the reliability of digitized radiographic comparisons for the purposes of dental identification. Participants with various forensic backgrounds and experience levels were passively recruited to the website. Ten forensic identification cases composed of antemortem and postmortem dental radiographs were supplied to examiners using a bespoke website. Participants responded to the cases on two occasions after a one-month washout interval using the ABFO conclusion levels for forensic identifications. A total of 115 first attempts and 87 matched second attempts were received. Of the total responses, 72% were dentally trained respondents who had completed at least one forensic identification case; of these, 38% were experienced forensic dentists who had completed more than 25 identifications. Data relating to accuracy, intra- and inter-examiner agreement, and the effect of case difficulty are presented. Mean accuracy was 85.5% for all cases, with the experienced forensic dentists obtaining a 91% success rate. The inter-examiner agreement on the negative identification cases was classified as poor. The data suggest that dental identifications resulting from the comparison of postmortem and antemortem radiographs are valid, accurate, and reliable when undertaken by experienced odontologists.  相似文献

The Institute of Medicine (IOM) has released the latest publication in its campaign to curtail medical error: Leadership by Example: Coordinating Government Roles in Improving Health Care Quality. In this publication, the IOM recommends that the government utilize its position as the country's largest purchaser of healthcare to institute unified performance standards, create appropriate incentives to improve quality of care, and develop a system to disseminate provider-specific quality information to the public. The author examines these recommendations and the contents of IOM's prior publications and concludes that necessary predicates of IOM's vision are rationing of care and a two-tiered system of healthcare. Thus, if the IOM's recommendations are carried out, the author envisions a healthcare system in which truly state-of-the-art care can only be purchased out of pocket. He concludes that, although Leadership by Example is a rational plan to address escalating healthcare costs, it is unclear both whether the American public would support it if the IOM were explicit about its ultimate impact, and whether the recommendations, in the long run, will prove to be a good thing.  相似文献
