A method ist described to determine the CO-content in the tissue of muscles. The prepared tissue is pulverized in a swinging mill at the temperature of liquid nitrogen. Parts of the powder are weighed into headspace vessels. Carbon monoxide ist ejected by a formerly described method and measured gaschromatographically. The Fe-content is determined after an acid disintegration by AAS. Acute intoxications lead to higher CO-contents in heart than in periphere muscles. Chronic exposure to carbon monoxide does not produce these differences.  相似文献

Presented in this paper are the initial results involving the use of the nose or outer ear as temperature measurement sites to determine the postmortem period of the human corpse. Simple mathematical models for both sites are developed based on cooling curves of five corpses. Analysis of errors between actual and calculated postmortem intervals suggest that in its present form, the described methods would not be suitable for use in accurately determining the time since death of human corpses.  相似文献

A case of kidnapping involving the concept of paternity testing is described. The couple arrested and charged with kidnapping stated the child in their possession was their biological daughter. Serological tests were performed on liquid blood samples in an effort to determine if the couple could have been the biological parents of the child. Two genetic inconsistencies were discovered in the 15 blood marker systems analyzed.  相似文献

Many scholars in International Relations (IR) have drawn from popular films to examine various problématiques that have informed the discipline's main theorisations. As Cynthia Weber remarks, popular films are powerful because they engage in the very ‘serious political work’ of mythologising the ‘truths’ and ‘realities’ which provide the foundation for many of IR's main theoretical envisionings of our world. To date, however, children's films have received very little attention. For the purpose of this paper, three have been isolated: Toy Story (1995), A Bug's Life (1998) and Rescue Heroes: The Movie (2003). Children's films, it can be argued, help to craft and restore certain perspectives for each new generation of young minds during the crucial years when the world is being textualised for the first time. The objective of this paper, therefore, is to read these films as working towards producing and sustaining the power/knowledge that seeks to defend contemporary forms of world order while concurrently extending and disseminating the rule of these forms of world order through the medium of children's popular cinema.  相似文献

If categories of 'race' and nationality are social and historical constructions laden with irrefutable meaning and consequences, then ethnic identities, like any other forms of identity, are means to other ends that may or may not be particular. Twentieth‐century indigenist history in Brazil reveals how the cultural politics of indigenism and nationalism can coalesce in a tautological politics of identity that undermines individual liberty and democratic heterogeneity. The concepts 'post‐indigenism,'post‐nationalism' and 'post‐identity' point to the strategic suspension of the infinite heterogeneity of the political subject as a means to widen the ground of shared experience and common interests beyond the realm of hollow and oppressive essentialisms.  相似文献

The present study examines the extent to which neighborhood and social psychological influences predict childhood violence among 867 African‐American youth. The results showed that neighborhood affluence was the only neighborhood‐level variable to exert a significant influence on childhood violence. Furthermore, childhood violence was significantly related to social psychological influences, such as adopting a street code, associating with violent peers, parental use of violence, and quality parenting. Overall, the findings suggested that simply living in a violent neighborhood does not produce violent children, but that family, peer, and individual characteristics play a large role in predicting violence in childhood.  相似文献

The social development model (SDM) is a theory of behavior that has proven useful in explaining the etiology of delinquency, violence, and substance use among adolescents as well as early antisocial behavior among pre-adolescents. A further test of the model is its generalizability across population groups. A section of the SDM representing prosocial influences in the etiology of problem behavior was compared for boys and girls and for children from low- and non low-income families using three waves of child, parent and teacher survey data on a sample of 851 elementary school students. Multiple group structural equation modeling was used to assess differences across groups in both measurement of model constructs and hypothesized structural paths between constructs. The results indicate overall similarity in the reliability of measurement models and validity of structural models.  相似文献
