This study uses data from an experimental employment program and instrumental variables (IV) estimation to examine the effects of maternal job loss on child classroom behavior. Random assignment to the treatment at one of three program sites is an exogenous predictor of employment patterns. Cross-site variation in treatment-control differences is used to identify the effects of employment levels and transitions. Under certain assumptions, this method controls for unobserved correlates of job loss and child well-being, as well as measurement error and simultaneity. IV estimates suggest that maternal job loss sharply increases problem behavior but has neutral effects on positive social behavior. Current employment programs concentrate primarily on job entry, but these findings point to the importance of promoting job stability for workers and their children.  相似文献

Any witness who is not able to testify due to lack of support or protection is a loss to the proper functioning of a criminal justice system. In this context it is generally accepted that creating a climate for witnesses to testify truthfully and without fear of reprisals is essential to fulfilling the goals of truth and justice. Accordingly, addressing the issues of witness protection and support is a central aspect of a well-functioning criminal justice system; one that contributes not only to the rule of law through more effective investigations and trials, but also ensures that witnesses are treated with the recognition and care they deserve for their contribution to finding the truth. The principle that victims in the criminal justice system must be treated with courtesy, compassion and respect for their personal dignity entails a responsibility on the part of national authorities to realise this basic principle through the development of appropriate mechanisms designed to provide assistance to the victims. However, building effective national victims/witness support and protection is challenging for any state, and especially so for small Commonwealth jurisdictions due to capacity and other constraints. The Commonwealth seeks to provide technical assistance and capacity building to support its members in promoting the rule of law and has developed and disseminated a best practice guide for the protection of victims and witnesses in the criminal justice system. This article seeks to highlight the valuable findings of the Commonwealth guide and to provide guidance to policy-makers, legislators, police, prosecutors and other stakeholders in criminal justice practice.  相似文献

While studies have documented the importance of strong implementation in intervention studies (e.g., see Durlak & Dupre, 2008 Durlak , J. A. , & Dupre , E. P. ( 2008 ). Implementation matters: A review of research on the influence of implementation on program outcomes and the factors affecting implementation . American Journal of Community Psychology , 41 , 327350 .[Crossref], [PubMed], [Web of Science ®] [Google Scholar]), more information is needed about how to ensure strong fidelity and quality of program implementation when delivering interventions under “real world conditions” and on a large scale. In this article, key lessons in implementing a demonstration and evaluation project known as the Foundations of Learning (FOL) demonstration are presented. Our discussion highlights several key components to the success of the project, including the building of effective coalitions before, and during, the delivery of the intervention to support the implementation process, as well as intensive, collaborative, and multilayered technical assistance provided as the intervention was delivered. Key lessons learned over the course of this project represent some that are highly consistent with prior research on this topic, as well as some that are unique, thus representing new areas for exploration in this burgeoning area of study.  相似文献

The relationship between physical assault upon parents by their offspring and social and psychological variables is analyzed in this study of 445 California families, half of whom are Hispanic and half Anglo. Results indicate that the assaulting of parents reflects a generalized pattern of negative parent-child relationships and diminished sense of well-being by youngsters.  相似文献
