A unique case of congenital bilateral absence of parietal bones in a neonate

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.     

SCHOOLS AS COMMUNITIES: THE RELATIONSHIPS AMONG COMMUNAL SCHOOL ORGANIZATION,STUDENT BONDING,AND SCHOOL DISORDER*

Research has indicated that school factors such as communal school organization and student bonding are predictive of school disorder, with greater communal organization and greater student bonding leading to less delinquency and victimization. Data from a nationally representative sample of 254 public, nonalternative, secondary schools were used to examine structural equation models representing hypothesized relationships among communal school organization, student bonding, and school disorder. The hypothesis that communally organized schools would have less disorder held true for teacher victimization and student delinquency, but not for student victimization. In addition, the hypothesis that the relationship between communal school organization and school disorder would be mediated by student bonding was supported for student delinquency, but not for teacher victimization.     

Adaptation and Appropriation on the Colonial Frontier: Indigenous Leadership in the Colombian Chocó, 1670–1808

This article explores the consequences for the native population of the Colombian Chocó of the emergence, over the course of the eighteenth century, of an elite of caciques and indios mandones or principales whose functions of powers far exceeded those of the warrior chiefs that had traditionally acted as leaders of their people. Appointed for the purpose of facilitating the collection of tribute and the supply of labour to European settlers, caciques and mandones were almost universally rejected by native communities during the early phases of Spanish colonisation (c. 1630–1690), and they disappear from the historical record after Independence. Eighteenth‐century sources, however, not only record the existence of a clearly defined elite of mandones or principales in villages across the region, but show these individuals engaging actively with the colonial authorities, on behalf of their communities, at local and audiencia levels. This article argues that, at a time of a much strengthened European presence in the region, caciques and mandones came to understand their roles in ways that were entirely different from those intended by the Spanish, and in so doing acquired the legitimacy that had eluded their seventeenth‐century predecessors. Far from serving merely as intermediaries between settlers and indigenous populations, indios mandones acted as negotiators on behalf of the indigenous population, whose task was to defend and/or advance the interests of the communities they had been appointed to control.     

Ethnicity, gender, and the Level of Service Inventory-Revised

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.     

Radiographic demonstration of esophageal and tracheal fistulas at autopsy using a contrasting medium that vulcanizes at room temperature

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.
