Although parental compliance with court orders in child welfare cases is key to achieving physical parent‐child reunification and successful case closure, little research has examined how parent‐child relationship‐focused rehabilitative services uniquely influence case outcomes. This project fills this gap by investigating links between court ordering of and parental participation in Child‐Parent Psychotherapy (CPP) with court outcomes. Data were obtained from court records of 448 court‐involved parents. Hierarchical regressions revealed that greater participation in CPP led to reunification and successful case closure but not faster case closure. Courtroom professionals should consider parent‐child relationship‐based therapies as tools for achieving child welfare goals.  相似文献

本文对中东欧国家自1989年以来发生的后社会主义制度转型进行了理论和现实的阐释,考察了其历史特性,批驳了该地区已经在制度上成为完全成熟的市场经济体的论点,而认为中东欧国家在转型方面还有很长的路要走.文章强调,后社会主义市场转型进程不会呈直线型发展.在现实社会主义经济体的市场改革与后社会主义市场转型之间存在着巨大差异.只有在更加精确地确定目标,同时不是将制度转型当作是自我实现的目标的前提下,不同国家在不同程度上才会取得更好的转型绩效,否则会朝相反方向发展.  相似文献

The aim of this five-wave longitudinal study was to investigate the relationship between anxiety and adolescent identity development. Participants were 1,313 adolescents who annually completed measures of anxiety and identity. Growth Mixture Modeling (GMM) analyses demonstrated that the adolescent population was best typified by two latent growth trajectory classes: a low anxiety class (n = 1,199) characterized by a low initial level of anxiety that decreased over time and a high anxiety class (n = 114) characterized by a higher initial level of anxiety that increased over time. To answer our research question, we tested a model in which the anxiety classes predicted initial levels and rates of change of three identity dimensions: commitment, in-depth exploration, and reconsideration of commitment. Findings indicated that the high anxiety adolescents displayed a more troublesome identity development than their low anxiety peers, since their commitments became weaker with age, and they reconsidered them intensively.

The literature on intelligence analysis contains many references to the ‘review process’, the mechanism by which analysts’ drafts are converted into corporate products. Analysts whose drafts consistently navigate the process quickly and smoothly are regarded as star performers. Divining the practical meaning of organizational definitions of ‘good’ analysis and the personal preferences of specific senior reviewers is not easy, however. Analysts occasionally commit their understanding of reviewers’ stylistic preferences to paper, effectively providing style guides to help others. This essay presents and explains the development and implications of one such guide, which was designed to help analysts in CIA’s Office of Strategic Research in the early 1970s.  相似文献

This paper deals with the long-term evolution of dock labor in Dakar. Through the utilization of archival sources and their analysis, this investigation explores the changes that occurred in this sector and primarily the reform plan developed during the world wars but that was never introduced into the labor regulations, mainly due to the colonial regime. In addition, this paper studies the legal changes since the 1970s when the dockers’ statute was settled. Furthermore, this research uses oral testimony from retired Senegalese dockers to study the way these workers observed these structural changes. It is the first time that this topic has been explored for the port of Dakar from a historical long-term perspective.  相似文献
