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

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

According to David Garland (1990) scholars should be concerned about the cultural foundations of punishment in modern western society, such as religion. To this end, Garland conceptualizes punitive mentalities and sensibilities that provide the cultural support for structural systems ofpunishment. Punitive mentalities are ways of thinking about punishment, whereas punitive sensibilities are ways of feeling about punishment. Garlandsuggests that religious traditions are an important source of punitive mentalities and sensibilities. This research is an empirical analysis ofpunitive mentalities and their cultural roots, using qualitative research.Research questions focus on the following: Are there distinctively punitivementalities? How do punitive mentalities influence the desire for officialpunishment? Data from a previous study (Cook, 1998a) are analyzed here to explore terrains of punitive mentalities within the contexts of Christianity.Findings identify four distinct categories: anti-punitive, non-punitive,retributive and vengeful mentalities where Christian (non)belief systemsare important cornerstones. Respondents in each group have specific desires regarding the state's use of punishments, especially the ``death penalty''.  相似文献
