The juvenile justice system established in Scotland in 1971, in which lay volunteers play a central part, provides a framework for making decisions about children in need of care and protection as well as those who have committed delinquent acts. Although cases of child abuse and neglect have come increasingly to the attention of children's hearings in recent years, they nevertheless constitute a small fraction of a workload dominated by cases of delinquency and truancy. A recent Scotland-wide study of the hearings system therefore gave only limited attention to the processing of abuse and neglect referrals. As a step towards rectifying this imbalance, a separate enquiry was carried out in 1981, when 43 such hearings were systematically observed and the participating panel members interviewed. Examination of these results indicates a heavy dependence on social workers' recommendations, a reluctance to open up sensitive areas for discussion, even though these may be of central importance, and an apparent lack of curiosity about the arrangements made for children removed from their homes, and the implications of these. In general, it is concluded that the anxiety generated by child abuse and neglect has prevented panel members from recognizing the distinctive features of their role in the decision-making process and has led them to fall back on an inappropriate model of practice derived from delinquency hearings. An alternative model is outlined.  相似文献

The authors present a study of comprehension as a function of the stimulation-seeking motive in relation to the degree of structure involved in information presented in film. While no significant effects were obtained in measuring comprehension of verbal and pictorial stimuli and literal and inferential processing, the stimulation-seeking motive may have had a moderating effect on the relationship among memory or information-processing systems. This would indicate possible differential-encoding or information-processing strategies between individuals high and low in the stimulation-seeking motive.  相似文献

The library of the Royal Medical Society of Edinburgh, which has been in existence for nearly 250 years, was sold by Sotheby & Co. of London at three auction sales during 1969. The author describes her attendance at the three sales, with emphasis on the most valuable items sold and the considerable acquisitions made for the Middleton Medical Library of the University of Wisconsin. Concluding observations concern some of the practical problems of acquiring antiquarian books at auction.  相似文献
