The remains of an unidentified female neonate were discovered in a field in central Missouri. Examination revealed bilateral absence of the parietal bones. A search of the literature describing similar defects suggests that the present case represents a unique condition, described here for the first time.  相似文献

This article focuses on media reportage of offensive juveniles, past and present, to elicit lessons that the twenty-first century can learn from the Victorian past in terms of diversionary responses. How to prevent vulnerable juveniles sliding into dangerous criminality is a continuing preoccupation: the issue explored in this article relates to the creation of the identity of the criminal juvenile. In utilising the concept of semi-criminality to label certain types of juvenile anti-social behaviour the Victorians avoided actual criminalisation of socially offensive but, in legal terms, minor behaviours. The reasons for and negative consequences of the abandonment of this concept by the modern age are explored, including the reconceptualisation of where responsibility for juvenile offending lies in the modern era.  相似文献

This article revisits the Baroda Incident 1875, providing a detailed examination of the Enquiry or ‹trial’ for the first time, and locating that examination in the wider socio-cultural context of the nineteenth century British Empire (especially the Raj) and the exporting of the ‹British’/English legal culture to the Empire. The implications of the establishing of British principles of justice, including the value placed upon Indian-generated evidence and testimony by the courts, are explored, in order to establish the Baroda Incident as a significant miscarriage of justice. Using historical methodologies as well as postcolonial insights, it demonstrates that the concepts of justice on which the British prided themselves were intrinsincally racialised as well as gendered, with profound modern resonances.

Aggressive pursuit of free trade agreements (FTAs) and customs unions (CUs) by major and minor trading powers alike challenges the conventional wisdom in favor of such pursuit – competitive liberalization. An equally plausible explanation for an active bilateral and regional trade agreement policy, one which effectively de-emphasizes multilateralism, may be competitive imperialism. The protection and enforcement of intellectual property rights is one area in which new provisions, going beyond multilateral rules, are being negotiated and written into FTAs and CUs. Such provisions may yield insights into which characterization of bilateralism and regionalism – competitive liberalization or competitive imperialism – is more apt.

Offender assessment and classification is becoming an increasingly important part of correctional supervision and intervention. Over the last several decades, several different methods and “generations” of offender classification have emerged. Of most value appear to be third-generation, actuarial, dynamic risk/need assessments. With any new correctional strategy, however, there is a need to investigate the use of these risk/need assessments on offender subgroups in order to inform issues, such as reliability and prevalence of criminogenic risk factors. The present study utilized data that were gathered using the Level of Service Inventory-Revised (LSI-R). Results and comparisons of these assessments were investigated and presented for Native American and non-Native American offenders as well as male and female offenders. Discussion of the results, implications, and recommendations for further research are presented.  相似文献

Esophageal and tracheal fistulas, which occur in 0.05% of medicolegal autopsies, were demonstrated in three cases by a postmortem radiographic technique using silicone rubber/lead oxide as a contrasting medium that vulcanizes at room temperature. In one 83-year-old male, a tracheoesophageal fistula was detected, which had developed after surgical repair of an esophageal rupture caused by a flexible fiberoptic endoscope. In a second case, carcinoma of the esophagus in a 78-year-old male had eroded the trachea and arcus of the aorta creating a fatal tracheoesophagoaortic fistula. In a third case, 55-year-old female developed a tracheobrachicephalic artery fistula as a result of an infiltrating cystic adenocarcinoma of the trachea, resulting in a fatal hemorrhage into the trachea. The results of this study indicate that diagnostic radiologic methods using a vulcanized contrasting medium are useful in supplementing normal dissection in autopsy cases with suspected fistulas of the esophagus or trachea.  相似文献
