The case of Jeffrey Dahmer: sexual serial homicide from a neuropsychiatric developmental perspective
Sexual serial homicidal behavior has received considerable attention during the last three decades. Substantial progress has been made in the development of methods aimed at identifying and apprehending individuals who exhibit these behaviors. In spite of these advances, the origins of sexual serial killing behavior remain for the most part unknown. In this article we propose a biopsychosocial psychiatric model for understanding the origins of sexual serial homicidal behavior from both neuropsychiatric and developmental perspectives, using the case of convicted serial killer Jeffrey Dahmer as the focal point. We propose that his homicidal behavior was intrinsically associated with autistic spectrum psychopathology, specifically Asperger's disorder. The relationship of Asperger's disorder to other psychopathology and to his homicidal behavior is explored. We discuss potential implications of the proposed model for the future study of the causes of sexual serial homicidal crime. 相似文献

The authors report two suicides that resulted from the intentional inhalation of automobile exhaust gases in which death occurred without the formation of physiologically significant amounts of carboxyhemoglobin. These circumstances are correlated with measurements of the involved vehicles' exhaust gases, which showed reduced concentrations of carbon monoxide present, reflecting improvements in automobile engine technology. In the absence of carbon monoxide toxicity, the authors attribute death in these cases to asphyxia caused by carbon dioxide intoxication and diminished atmospheric oxygen concentrations. 相似文献

Some who have written about the logic of experimentation arguethat random assignment of subjects to treatment conditions isan essential attribute of an experiment. Others disagree. Ratherthan treating this as a matter of dueling definitions, we considerexperiments without randomization from a theoretical perspective.Our central contention here is that, for some research questions,theory dictates systematic (not random) assignment of respondentsto experimental conditions. Two such areas of inquiry are researchon political tolerance and on institutional legitimacy. Thisarticle gives cursory attention to the former body of work anddetailed attention to the latter, based on an experiment conductedin a survey in 2001 on the consequences of the American presidentialelection for institutional legitimacy. Because in both instancestheory requires nonrandom assignment, the problem becomes oneof identifying the costs of nonrandomization (threats to internalvalidity) and specifying analytical techniques that might amelioratethose costs. Consequently, we present results from a statisticalapproach that addresses the problem of nonrandomization. Themost important claim of this article is that theory ought tospecify research design, including experimental designs, andthat dogmatic attachment to one definition of experiment willnot serve the discipline of political science. 相似文献

The goal of this study was to compare the responses of late adolescent and young adult children of divorce and nondivorce on a new multidimensional measure of parentification assessing the extent and fairness of past and present caregiving in one's family of origin. Three-hundred-and-eighty-two individuals participated. Item analyses and internal consistencies of the different parentification scales were initially conducted on one-half of the sample and cross-validated on the other half. The scores of European and African American participants from the validation sample whose parents either divorced before middle adolescence (N = 35) or never divorced (N = 68) were then compared. The divorced group reported providing more emotional and instrumental caregiving and experiencing more unfairness in their families of origin than did the nondivorced group, although the effect for emotional caregiving was moderated by temporal perspective. Evidence that problematic forms of parentification in children of divorce continue into late adolescence and young adulthood has implications for models of understanding and helping these children and their families. 相似文献
