Tracing the use of electrical torture   总被引:1,自引:0,他引:1  
With the aim of being able to trace skin sequelae to electrical torture, an interdisciplinary group of scientists (the "electrical group" of Anti-Torture Research, ATR) has performed controlled morphological studies on skin biopsies from experiments with fully anesthetized pigs. "Vesicular nuclei" in epidermis and a characteristic pattern of collagen calcification in dermis were found to be typical of electrical damage. These alterations were produced by alternating current as well as by direct current.  相似文献

A recently completed study of the Scottish juvenile justice system, employing a variety of methodological approaches, is used as a source of information on the behavior and attitudes of the lay volunteers who make up children's panels and are responsible for decisions concerning young people who are alleged to have committed an offense or are believed to be in need of care and protection. The reported data relate to the beliefs of panel members as to the causes of delinquency and the objectives of intervention and alternative disposals; the topics they raise for discussion in children's hearings and the factors which influence the decisions they make; and the manner in which they are perceived by the children and parents who have appeared before them.  相似文献

The purpose of this study was to test the hypothesis that suicidal ideation is a common experience in a general population of African American, Hispanic, and White urban high school students residing in low-income neighborhoods. Based upon a developmental framework, it was hypothesized that once attitudes toward suicide were controlled, ideation would not vary significantly by ethnicity, gender, or psychosocial variables usually associated with ideation. The multivariate analysis revealed that ideation did not vary by ethnicity however, females, substance users, and those with greater tolerance toward suicide, higher family coping, and lower self-esteem were more likely to report ideation. A series of ideator profiles, calculated from the probability estimates, showed that an increase in tolerance substantially raises the likelihood of ideation. The results taken together raise the question of whether it is time to reconceptualize the relationship between ideation and normal adolescent development.  相似文献
