This study examined the progress and disposition of child sexual abuse cases referred for prosecution in four urban jurisdictions. Most cases were accepted for prosecution. The vast majority of cases carried forward for prosecution resulted in guilty pleas. Only 9% of the total sample went to trial. A majority of the small number that went to trial were convicted. Over 3/4 of those convicted were incarcerated. The rate at which cases were carried forward for prosecution and convicted was comparable to that of a national sample of felony arrests overall, but child sexual abuse cases were more likely to go to trial (p < .005) and received more severe sentences (p < .005). Our results are strikingly consistent with those from previous studies of prosecution of child sexual abuse. A new understanding of prosecution of child sexual abuse is recommended that takes into account the large proportion of cases that do not go to trial. 相似文献

Since the turn of the century large groups of former institutionalised children have exercised their right to see their ‘personal files’, and this has drawn widespread attention to these documents and their potential in scholarly research. This article explores the meanings of personal files from the period 1945–1984 as sources for both historical researchers and adult care leavers themselves, in the context of the orphanages in Ghent, Belgium. Based on the experiences of those who have consulted their files, we come to the conclusion that the personal files of the Ghent orphans provide some new information but, at the same time, leave a lot of issues unresolved. Although the files offered significant insights for researchers studying the most recent period in the history of the Ghent orphanages, it is difficult to see them as ‘keys to the past’ for former orphans who are trying to (re)construct their own, individual life histories. 相似文献

This article considers the transmission of knowledge in higher education. It takes the metaphor of the music industry that pre‐selects the music people can buy. The sales potential is the leading principle in the selection process. Often the small producer is excluded because his or her music is not of commercial interest. The end‐customer does not know what he or she is missing because he or she has never heard the music. It is to be feared that a similar market principle will also influence the selection of knowledge and affect the capacity of higher education institutions to freely generate and transmit new knowledge. The globalization of higher education risks homogenizing the cultural traditions of the non‐Western world through a process of Western cultural domination. On the other hand, the Internet, via open source software like LINUX, might serve to democratize higher education and allow greater grassroots input. 相似文献

For the past few years a discussion has been going on about the specific skills and knowledge a complete engineer should possess. Apart form this discussion, a separate debate has focused on the content of an engineer's education. This article is a combination of two joint papers (De Graaff and Ravesteijn 2000, Ravesteijn and De Graaff 2000) bearing on these respective subjects, presented by the authors at the SEFI 2000 conference in Paris. The demands from industry that engineers of the future will have to meet are summarized and related to characteristics of modern training methods. It is argued that a new view on the content of the engineer's education implies, at least to a certain extent, a new set of educational tools. 相似文献

Podcasts offer a way for medical professionals to listen to current information in medicine from an iPod, MP3 player, handheld device, or computer. As podcasts become more popular, libraries may be interested in integrating programs into the library collection. South Pointe Medical Library evaluated medical podcasts relevant to the scope of the library collection and explored methods for finding and organizing such programs in ways that are efficient for both the librarian and the patron. doi:10.1300/J115v26n01_03. 相似文献

For this study, information on Who Bullies Who was collected from 54 school classes with 918 children (M age = 11) and 13,606 dyadic relations. Bullying and victimization were viewed separately from the point of view of the bully and the victim. The two perspectives were highly complementary. The probability of a bully-victim relationship was higher if the bully was more dominant than the victim, and if the victim was more vulnerable than the bully and more rejected by the class. In a bully-victim dyad, boys were more often the bullies. There was no finding of sex effect for victimization. Liking reduced and disliking increased the probability of a bully-victim relationship. 相似文献
