It has long been established that illicit drug use contributes to child maltreatment. However, investigators have yet to comprehensively examine illicit drug use in mothers referred to treatment by Child Protective Services (CPS). In this study, 77 mothers who were referred to treatment by CPS for co-existing drug abuse and child neglect were administered the Timeline Follow-Back measure to assess their substance use frequency during the four months preceding treatment. Reports of the mothers’ substance use were obtained for the same time period from the mothers’ significant others and CPS caseworkers, and mothers were administered urinalysis testing. The purpose of this study was to examine the concordance of these multiple reports, and identify unique predictors of different drug use reporting patterns. The practice of using urinalysis results as a prompt during the mothers’ Timeline Follow-Back administration may have contributed to greater frequency of drug use reporting in mothers. Mothers reported progressively more drug use for more distant time periods, as compared with caseworkers. Findings also suggested mothers’ reports of drug use were influenced by CPS investigatory case status (i.e., open or closed), ethnicity, and defensive responding. Implications of these findings for clinical practice and future research are discussed.  相似文献

In Rossettiren obsesioa (Rossetti's Obsession), a short and explicitly meta-literary novel published in 2000, Ramon Saizarbitoria presents a Basque writer wrestling a formidable lover: the Spanish readership. The question that Eugenia, the woman from Madrid, constantly asks the writer, “¿Qué os pasa a los vascos?” (“What's wrong with you Basques?”), encapsulates the ambiguity of the relationship which unites these two indisputably allegorical characters. The difficult interaction between the powerful Spanish literary field and the emerging Basque literary field, doomed to coexist and moved by reciprocal feelings of fascination and irritation, becomes the novel's subject matter. Is translation – and its corollary, an access to a larger literary market – a pure and neutral instrument of liberation for the writer who expresses himself in a minority language, or could it become, in certain circumstances, a threat to his autonomy?  相似文献

Case linkage involves identifying crime series on the basis of behavioral similarity and distinctiveness. Research regarding the behavioral consistency of serial rapists has accumulated; however, it has its limitations. One of these limitations is that convicted or solved crime series are exclusively sampled whereas, in practice, case linkage is applied to unsolved crimes. Further, concerns have been raised that previous studies might have reported inflated estimates of case linkage effectiveness due to sampling series that were first identified based on similar modus operandi (MO), thereby overestimating the degree of consistency and distinctiveness that would exist in naturalistic settings. We present the first study to overcome these limitations; we tested the assumptions of case linkage with a sample containing 1) offenses that remain unsolved, and 2) crime series that were first identified as possible series through DNA matches, rather than similar MO. Twenty-two series consisting of 119 rapes from South Africa were used to create a dataset of 7021 crime pairs. Comparisons of crime pairs that were linked using MO vs. DNA revealed significant, but small differences in behavioral similarity with MO-linked crimes being characterized by greater similarity. When combining these two types of crimes together, linked pairs (those committed by the same serial offender) were significantly more similar in MO behavior than unlinked pairs (those committed by two different offenders) and could be differentiated from them. These findings support the underlying assumptions of case linkage. Additional factors thought to impact on linkage accuracy were also investigated.  相似文献

This article describes four demonstration projects that strive to promote responsible behavior with respect to parenting, child support payment, and employment among incarcerated and paroled parents with child support obligations. These projects, conducted in Colorado, Illinois, Massachusetts, and Texas, with support from the federal Office of Child Support Enforcement and evaluated by the Center for Policy Research, led to a number of common outcomes and lessons. The projects revealed that inmates want help with child support, parenting, and employment and that prisons can be effective settings in which to conduct such interventions. Family reintegration programs were popular with inmates and may have helped to avoid the rupture of parent–child relationships commonly associated with incarceration. Although employment is the key to child support payment following release, rates of postrelease employment and earnings at all project sites were low and the employment programs were of limited utility in helping released offenders find jobs. Agencies dealing with child support, employment, and criminal justice need to adopt more effective policies with incarcerated parents including transitional job programs that guarantee immediate, subsidized employment upon release, child support guidelines that adjust for low earnings, and better training and education opportunities during incarceration.  相似文献

New Hope, an employment‐based poverty‐reduction intervention for adults evaluated in a random‐assignment experimental design, had positive impacts on children's achievement and social behavior two and five years after random assignment. The question addressed in this paper was the following: Did the positive effects of New Hope on younger children diminish or even reverse when children reached the challenges of adolescence (eight years after random assignment)? Small positive impacts on school progress, school motivation, positive social behavior, child well‐being, and parent control endured, but impacts on school achievement and problem behavior were no longer evident. The most likely reasons for lasting impacts were that New Hope families were slightly less likely to be poor, and children had spent more time in center‐based child care and structured activities. New Hope represents a model policy that could produce modest improvements in the lives of low‐income adults and children. © 2011 by the Association for Public Policy Analysis and Management.  相似文献

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
