A unique mediation service using the telephone to help parents resolve conflicts over visitation ("access") is described. The program presented special advantages of low cost and high responsiveness to parents and their children and was designed to particularly benefit families that lacked the mobility or financial resources to participate in traditional face-to-face mediation. Because the service featured highly educated and experienced mediators and a child-focused, principle-based mediation approach, family members received reframing, refocusing, informative, and empathic assistance in understanding and dealing with their parenting disputes. Some 700 families and nearly 900 mediation cases were handled during the service's 19 months of operation, and some features of the families and the cases are described. Recommendations and directions for future research are included.  相似文献

The National Health Service (NHS) in England and Wales has embarked upon a radical and far–reaching programme of change and reform. However, to date the results of organizational quality and service improvement initiatives in the public sector have been mixed, if not to say disappointing, with anticipated gains often failing to materialize or to be sustained in the longer term. This paper draws on the authors' recent extensive research into one of the principal methodologies for bringing about the sought after step change in the quality of health care in England and Wales. It explores how private sector knowledge management (KM) concepts and practices might contribute to the further development of public sector quality improvement initiatives in general and to the reform of the NHS in particular. Our analysis suggests there have been a number of problems and challenges in practice, not least a considerable naïvety around the issue of knowledge transfer and 'knowledge into practice' within health care organizations. We suggest four broad areas for possible development which also have important implications for other public sector organizations.  相似文献

The conditions affecting an enzyme-linked immunosorbent assay for salivary blood group substances were investigated. It was found that A, B, and O secretor saliva samples would each bind both anti-A and anti-B typing reagents. The conditions that affected the assay response were optimized for maximum sensitivity and to give the highest resolution possible between the result for an antiserum binding to homologous antigen and the response for heterologous antigen-antibody combinations. Monoclonal antibodies eliminated the heterologous binding indicating that this binding was due to a lack of specificity of the routine typing reagents. A sensitive assay using the monoclonal antibodies to distinguish between samples of A and B secretor saliva is described.  相似文献

This essay examines the dubious relationship between the quality of criminal justice education and the kind of treatment faculty members and students receive from their academic administrators. It is based on three premises: criminal justice colleges and departments should be held to higher rational and moral standards not because they are qualitatively different from other liberal arts departments, but because they teach justice; if the virtues of criminal justice are worth teaching, then criminal justice faculty members and students should be treated in a manner consistent with these virtues; and treating criminal justice faculty members and students unfairly, disrespectfully, or irresponsibly makes them unable or disinterested in endorsing the noble nature of criminal justice. This article categorizes academic administrators as either Athenians or Spartans. The former are best suited intellectually and temperamentally to administer because they possess a talent for reasoning and act in good faith. The latter are unsuited because, regardless of how well they mask it, they practice domination, deception, favoritism, and indignity.This essay is a theoretical discourse based on the contiguity of modalities, experiences, and impressions generally shared by criminal justice educators and graduate students. Its logic is Humeian and its method is broadly ethnographic.  相似文献

The present 4-year follow-up study involves 56 mothers who were evaluated by social agencies as being abusive and neglectful or at high risk for child abuse and neglect. The aim of the study is to analyze the relationship between psychosocial risk factors (relating to the history and current situation of the mothers) that were present at the time the families were initially recruited and the fact that some of the mothers continue to show a high potential for child abuse and neglect (chronic abuse and neglect), whereas others were able to overcome the problem (transitory abuse and neglect). Results indicate that the following variables are particularly associated with situations involving chronic problems of abuse and neglect: initial level of severity of potential for abuse and neglect; dual-parent status; a large number of children at the time of intervention (3.13 times more risk of chronicity for large families); the fact that as a child the mother herself had been placed in a foster home (3.7 times more risk); that she had been sexually abused (3.5 times more risk); and that as an adolescent she had run away from home (3.02 times more risk). Our results indicate that mothers who have a combination of more than eight risk factors are four times more likely to be in the chronic group.  相似文献

This article examines the development of the German community in Hong Kong between the 1840s and the outbreak of the First World War. It pays particular attention to the question of how the Germans, as a minority group in the crown colony, attempted to strike a good balance between integration and segregation, cultural assimilation and dissimilation, national identity and marginalization. Through investigating their social life, missionary activities and economic activities in Hong Kong, it shows that they, on the one hand, cooperated closely with the British who were in charge of key political and economic affairs, and on the other hand worked with the local Chinese on different social stratums. Although the unification of Germany in 1870 strengthened the sense of nationhood among German people in Hong Kong, they strove to strengthen the German cultural and economic network that already existed in and around the colony, without sacrificing their business and social interests which were interwoven with those of the British and the local Chinese. It is this strategy that enabled them to survive in Hong Kong until 1914.  相似文献
