This preliminary communication describes seven babies with β-amyloid precursor protein (βAPP) positive axonal swellings in nerve roots at multiple levels of the spinal cord. All seven babies died of natural causes. Two died in utero providing evidence for nerve root injury in the absence of trauma, two died within one day of birth and the possibility of birth related injury has to be considered. Three babies were over one month of age and had no history or pathological evidence of trauma. These findings show that if axonal injury is carefully sought in every infant death, not just in babies where trauma is suspected, it will be found in a proportion of babies dying from natural diseases. While spinal nerve root axonal injury in infants may suggest trauma, it is not, in itself, diagnostic of trauma.  相似文献

Attention-deficit/hyperactivity disorder (ADHD) is characterized by a lack of concentration and/or an altered activation level. People with ADHD are found to violate traffic regulations, to commit criminal offences and to be involved in traffic accidents more often than the statistical norm. Furthermore, they show more deviant behaviour and have an increased co-morbidity regarding substance abuse and dependence. Hence, this disorder is of some forensic importance. The purpose of this case study is to demonstrate that in some cases people with ADHD may show unusual effects after the consumption of THC. A 28-year-old male, who showed abnormal behaviour and seemed to be significantly maladjusted and inattentive while sober, appeared to be completely normal with a very high plasma level of THC. Performance tests conducted with the test batteries ART2020 and TAP provided average and partly above-average results in functions related to driving. Thus, it has to be taken into account that in persons with ADHD THC may have atypical and even performance-enhancing effects.  相似文献

At autopsy, visualization of lesions of the bridging veins, a frequent source of subdural bleeding, is difficult due to their anatomical localization. On the other hand their demonstration is of great importance for the assignment to a chronologically defined trauma. For this reason a postmortem method using computed tomography was developed to visualize the intracranial venous system by means of X-ray contrast media. In subdural bleedings, in which the skull had not been opened up, ruptured vessels could be accurately localized with this method, so that targeted dissection was possible during the subsequent autopsy.  相似文献

Individuals direct their own development by setting developmental goals and striving for goal attainment. Human development includes reductions in discrepancies between desired and actual states, as is the case in goal attainment and reduction of aspirations, as well as increases of discrepancies, for example, when individuals increase their aspirations or face setbacks. The present study analyzed how ways of changing discrepancies between desired and actual states of solving developmental tasks relate to changes in adolescents' self-esteem across a 2-year period. With regard to discrepancy-reducing processes we found that increases in goal attainment were associated with increased self-esteem whereas reductions of aspirations were not systematically associated with self-esteem change. With regard to discrepancy-producing processes, diminishing of the present state was consistently associated with declines in self-esteem, whereas increases in aspirations showed inconsistent associations with self-esteem changes. The results indicate similarities and differences between developmental regulation in adolescence and adulthood.  相似文献

Successive Australian Labor governments have tried to nationalizestandards for the protection of rights either by means of astatutory bill binding on the states under the Commonwealth'smuch expanded external affairs power, or by further entrenchingspecific rights in the Constitution. All these attempts havefailed for a variety of political and constitutional reasonsincluding, importantly, the strength of Australia's establishedsystem of federalism and parliamentary responsible government.The article examines the constitutional issues underlying thedebate over a bill of rights for Australia, arguing that Labor'sattempts to implement a bill of rights have been inspired bya preference for more centralized government whereas the defeatof such initiatives indicates, the established strength of Australianfederalism.  相似文献

Nowadays, relational sociology is represented by sociological approaches from the US and from France. These approaches share the aim of recombining the two “mega-paradigms” in the social sciences, structuralism and pragmatism. Relational sociology is thereby conceived as a project integrating the analysis of different forms of social practices and structures. The article aims to identify the specific properties of relational sociology beyond this common basis. Starting with the “New York school of relational sociology”, it is shown that this school can on the one side be regarded as a contemporary approach of relational sociology, having introduced innovative contributions, but also shows deficient developments on the other side. Thereupon “actor-network theory” and “economics of convention” in particular are presented as examples of the “new pragmatic sociologies” in France, which can also be regarded as modern versions of relational sociology. After characterizing and comparing these three versions of relational sociology, their metatheoretical and particularly methodological commonalities are presented. Finally, the article tries to define positively what constitutes relational sociology.  相似文献

Previous research has noted a greater rate of depression among adolescent girls than boys (A. C. Petersen et al. [1993]; Depression in Adolescence, American Psychologist, Vol. 48, pp. 155–168; S. Nolen-Hoeksema [1987] Sex Differences in Unipolar Depression, Psychological Bulletin, Vol. 101, pp. 259–282). Explanations for this gender differential in adolescent reports of depressive symptomatology have been the focus of past scholarly attention (Petersen et al, 1993; D. B. Kandel and M. Davies [1982] Epidemiology of Depressive Mood in Adolescents, Archives of General Psychiatry, Vol. 39, pp. 1205–1232). Littk is known, however, about factors that underlie individual differences in adolescent girls' reports of depression. In this study, we explored individual differences in depressive symptoms as a function of young adolescent girls' gender role orientations (i.e., level of masculinity) and the degree of sex typing in their parents' marital roles. Participants were 89 seventh-and eighth-grade girls from white, rural, maritally intact families. Results revealed that girls who rated themselves as more masculine and their parents' marriage as more egalitarian were significantly lower in depression than other girls. Results of this study suggested that the potential positive effects of person characteristics associated with mental well-being (i.e., high masculinity) were moderated by family context (i.e., traditional families).The research reported in this paper was supported by funding from the Carnegie Corporation of New York.
