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.

如何认识世界资本主义和社会主义的发展--对《九论社会主义和资本主义发展的历史进程》一书的几点意见

本文指出权威性著作<九论>对世界资本主义和社会主义发展的看法多有不实之处;作者认为世界资本主义与社会主义的发展各自以历了互相对应的四个阶段,社会主义先在俄、中等不发达国家实现确是早产,理应补生产力不足的课,社会主义苏联模式失败的深层原因在于它渗透了沙皇俄国军事封建帝国主义的糟粕,违背了科学社会主义原理.     

论不动产利用的二元结构

不动产的利用主要有两种方式:一是设定用益物权,二是设定债权利用权。这两种方式尽管有相似之处,但仍有本质的区别。由于用益物权与债权利用权具有不同的利益、成本和风险,因此,对不动产利用而言,究竟应采取何种形式,对于当事人至关重要。     

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.
