More than two decades ago, Marmarou published a valid model for producing diffuse axonal injury (DAI) in rats. Since then, both mild and severe injuries have been obtained by researchers using the original method and a weight of 450 g. However, the diffuse brain injuries produced in rats were only similar to those seen in humans when the rats sustained severe brain injuries. In these cases, rat mortality in the original article was around 50%, and the cause of death was prolonged apnea post-impact. Rat survival after impact is critical for studying the progression of DAI. In order to explain the cause of death in human victims with cranial trauma who do not show gross brain injury, testing for the presence of DAI is essential. Thus, in order to minimize local and cervical injuries to increase rat survival, attention should be paid to the following aspects: a wider head protector disc should be used, the head of the rat should be elevated at the time of impact, and the foam bed should be soft enough to allow the movement caused by acceleration. With our modified method, rat survival increased by 30% compared to the original model (80% versus 50%). Moreover, 85.7% of rats demonstrated DAI after 24 h of survival. With these modifications, injuries appear in the same locations as in humans; thus, the method is suitable for the study of traumatic DAI in humans. 相似文献

Summarizes the author's life and how differences contributed to her selection of community psychology and to various choices she has made to further her goals. Focuses on her context within a colonial setting and on the significance of being a woman in her particular environment. Shows how clarity and steadfastness to ideals linked to divergent skills and a collaborative and participatory ideology have bred change. Signifies students' contributions to the generation of new energy as well as new conceptualizations. Finally, stresses the importance of international and interdisciplinary collaborations to enrich both our lives and the discipline of community psychology. 相似文献

The paper argues that the processes of informalization of jobs observed during the past decades have affected both high and low income countries. Starting at the micro level of the firm, the emphasis is on how economic restructuring and globalization have generated the growth of informal activities—resulting in the vicious circle of poverty and economic insecurity for an important proportion of the population. The second part of the paper analyzes the growth of women's participation in informal activities, emphasizing that there are contradictory forces at work regarding women's employment. Despite a stubborn persistence of gender discrimination and obstacles to women's advancement, progress has taken place on several fronts, such as in the education field and in the absorption of female labor in many production processes. The paper concludes by pointing out that poverty eradication programs must emphasize the need to generate decent jobs without which these programs will continue to be ineffective. In addition, re-distributive mechanisms and different forms of social protection are needed to counteract the forces and policies generating economic insecurity. 相似文献

The reform of the British system of welfare undertaken by the Labour government places a great emphasis on paid work, which is seen as the main route to escape poverty and the natural way to fulfil citizen obligations. Lone parents are a target group for welfare to work policies and, if they are on benefits, they are strongly encouraged to get a job. This article explores the main policies designed to promote employment among them—the New Deal for Lone Parents being the most significant—and the issues they raise. It is argued that the success of the welfare to work strategy for lone parents could be severely compromised without the consideration of at least two sensitive issues: the potential dangers of a compulsory scheme and the recognition of the relevance of caring activities and their integration into a more comprehensive concept of citizenship. 相似文献

DNA typing in a cattle stealing case. 总被引:2,自引:0,他引:2

DNA profiling was used as probative evidence in a cattle stealing case. The carcasses of the dead animals were found from a report and a farmer recognized the remains as those corresponding to the stolen animals by the farm mark on the coat. Those remains were collected as reference samples. Meat pieces were sequestered from a butchery and then sent to our Laboratory by the Justice Department of Buenos Aires (Argentine) to perform a DNA comparative analysis with the reference. Matches were found between the evidences and the references, supporting the hypothesis that the meat pieces had been obtained from the stolen animals. The butcher was suspected of stealing animals but no direct incrimination had been made yet. 相似文献

Spain is frequently the entrance country into the European Union for undocumented immigrants, especially those from the Magreb (Northern Africa). Forensic age estimates for these persons are difficult because systematic studies of dental maturity are lacking. Three different populations were analyzed to determine the pattern of development of third molars as a tool for age estimation in people of different ethnic and geographic origin. Orthopantomograms from two different populations of Spanish origin (Galicia in northwestern continental Spain, and Ceuta, a Spanish province in Northern Africa) were compared to radiographs of molars from a Magrebian population (Northern Africa) resident in Ceuta. Orthopantomograms were obtained from a private dental clinic (n=344) in Galicia and from the Public Oral Health Services (n=228) in Ceuta. We looked for differences in third molar mineralization (determined with the Demirjian scale) that might serve as age indicators (older versus younger than 18 years). Differences in maturation patterns were found between sexes and populations of origin. Mineralization of tooth 38 was more advanced in males than females among subjects 18 years of age and older in all three populations. Moreover, mineralization of tooth 38 in subjects aged 18 years and older was significantly slower in the Spanish-Galicia population than in the Magrebian-Ceuta population. We found no significant differences between Magrebian and Spanish individuals from Ceuta. We conclude that differences in tooth 38 mineralization may be related more with socio-geographical than ethnic origin (ancestry), and thus constitute evidence of the relevance of socio-geographic rather than genetic factors in third molar development. We used ROC analysis to determine the accuracy of the examiner's ability to correctly estimate age as younger or older than 18 years. The results suggest that Demirjian stage for tooth 38 can be considered a good indicator of age in all three populations. 相似文献

This study investigates whether mothers who are neglectful and at high risk for child physical abuse present a deficit in empathy. Participants were neglectful mothers (n=37), mothers at high risk for child physical abuse (n=22), and nonmaltreating mothers (n=37). The Interpersonal Reactivity Index, a self-report measure assessing specific dimensions of empathy, was used to assess dispositional empathy. No differences between neglectful and non-neglectful mothers were found for perspective taking, empathic concern, and personal distress. High-risk mothers reported less perspective taking and more personal distress than nonmaltreating mothers. No difference between groups was found for empathic concern. The present study supported the hypothesis that parents at high risk for child physical abuse show a deficit in particular aspects of dispositional empathy: personal distress and perspective taking. However, no differences were found between neglectful and nonmaltreating mothers in any dimension of dispositional empathy. 相似文献
