Concern about the difficulties faced by child witnesses in the legal system has led to two major areas of reform: the relaxation of competence and corroboration requirements, and the introduction of special procedures and physical facilities to reduce the emotional pressures of testifying. Although the implementation of these measures depends largely on judicial discretion, little is known about judicial perceptions of child witnesses and about judicial acceptance of these measures. Fifty magistrates and judges in New South Wales, Australia were asked via interview or questionnaire about their beliefs, concerns, and practices related to child witnesses. There was considerable variability in their views about the competence of child witnesses and the need for special protective measures in court for these witnesses. There was, however, more consensus about those aspects of children's ability to testify that give rise to judicial concerns about their competence. Children's honesty was not at issue; they were generally regarded as being at least as honest as adults, if not more so. They were, however, perceived as highly suggestible and susceptible to the influence of others and prone to fantasy. These findings are consistent with the findings of other studies, and provide a basis for judicial education in relation to child witnesses.  相似文献

This paper investigates the changing status of research of women and education during the 1970s. All articles published in the American Educational Research Journal, the Journal of Educational Psychology, Child Development, Sociology of Education, and the Journal of Educational Measurement from 1973 through 1978 are included in this study. A total of 2239 research articles are identified and examined for article content and authorship. Of these articles, 13.5 per cent deal with women and education, 15.9 per cent are authored by women solely and 28.0 per cent are co-authored by women and men. There is a significant increase in the number of articles on women and education, and it appears that proportionately more of these articles are written by women; however, there is no proportional change in women's authorship of (1) total articles written by women, (2) articles on women and education, or (3) articles on topics other than women and education. It is concluded that women and education became a legitimate topic for scholarly inquiry during the 1970s, but that this increased legitimacy did not benefit women specifically.  相似文献

The article discusses a study conducted between December 2007 and March 2008 that involved 19 gender-stratified focus groups with African American parents and adolescents from Allegheny County, Pennsylvania, to explore the process and content of parent-adolescent communication about sex. Discussions about intimate partner violence (IPV) and healthy relationships emerge inductively as critical topics in these conversations. The authors use a grounded theory approach to content analysis to identify and organize themes related to discussions on these topics. A total of 125 participants from 52 families are recruited for the study. Family history of child sexual abuse often motivates discussions. Mothers are described as the primary parent discussing sexual issues with children. Fathers primarily role model ideal male partnership behavior for sons and daughters. Parents seek to prevent daughters from experiencing sexual abuse or emotional manipulation by partners and focus on instilling a sense of responsibility to and respect for romantic partners in sons. Parents prioritize and express the need for tools to influence their adolescent's socialization as romantic partners. Mothers and fathers approach this process differently. Family-focused interventions to prevent unhealthy relationships can build on parent's efforts.  相似文献

In literature, cases of nutmeg abuse have been described repeatedly, but only one fatal case of poisoning was reported [1]. In the present case, myristicin (4 microg/ml) was detected for the first time in the postmortal serum of a 55-year-old woman. Identification was achieved with the aid of UV-VIS spectroscopy and TLC; for quantification, HPLC was used. Because also flunitrazepam (0.072 microg/ml) was found, death had probably been due to the combined toxic effect of both substances. From 1996 to 1998, in a series of cases, seven poisonings with nutmeg were recorded by the Erfurt Poison Information Centre. Even where higher doses (20-80 g of powder) had been ingested, a life-threatening situation was never observed. In one of these cases, a myristicin blood level of 2 microg/ml was measured 8h after ingestion of two to three tablespoonful of nutmeg powder (approx. 14-21 g, or 280-420 mg/kg).  相似文献
