The causes of death of 53 severely to profoundly developmentally disabled patients who died in an intermediate care facility were reviewed. Respiratory disease, predominantly pneumonia and aspiration, accounted for 72% of deaths. Seven patients died of nonrespiratory causes, and in 8 patients, no cause of death could be determined, even after a complete autopsy or investigation. The median age at death was 20 years. The weights of these patients' organs at autopsy were lower than those for normal individuals of the same age. The lifespan of these severely impaired individuals continues to be significantly shortened, even with improved methods of care.  相似文献

This paper uses a heretofore untapped source of information in the National Crime Survey (NCS) victimization data—the interviewer narratives—to explore school-related victimizations among adolescents. These narrative reports provide important information bearing on lifestyle and routine activity theories of victimization that is simply not available from the more familiar, highly structured portions of the NCS questionnaire. The NCS narratives suggest that a large proportion of school-related victimizations stems from peer interactions that occur in the course of routine daily activities and escalate into victimizations. Students represent pools of both potential offenders and potential victims who come in frequent contact with each other, often in the absence of capable guardians. However, rather than predatory, calculated attempts to harm, school-related victimizations among adolescents appear to consist primarily of bullying, injured pride, and misguided mischief. The theoretical and methodological implications of this study are highlighted.  相似文献

This research contributes to a further understanding of prosecutorial discretion by exploring tenets of casual attribution theory and etiology of bias theory as each informs an uncertainty avoidance perspective on the prosecutor's decision to divert felony drug defendants from criminal prosecution and into a treatment program. The sociolegal consequences of the exercise of this early screening decision are expressed by both conflict theorists and labeling theorists. Our analysis involves estimating main effects and interaction effects of defendant ascribed status and achieved status on the likelihood of diversion. The findings indicate partial support for hypotheses derived, from the theoretical perspectives pursued. In addition these findings point to a more complex model of the subjective nature of the exercise of prosecutorial discretion, a model that benefits from understanding the salience of minimizing uncertainty in the decision to criminals.  相似文献
