Evidence-Based Solutions for Overcoming Access Barriers, Decreasing Attrition, and Promoting Change With Underserved Families.

Various definitions exist for what constitutes family therapy. In this article, we consider family therapy to encompass any intervention that targets family interactions and conceptualizes problems as existing beyond individual clients. Numerous individual studies and several quantitative reviews have established family therapy as an effective treatment modality and the treatment of choice for many disorders. However, critiques of existing service provision highlight the unfortunate fact that numerous barriers to treatment exist at multiple levels of the broader ecology, preventing many families from benefiting from these services.

Effect of nitrocarburizing on sulphide layer during nitrocarburizing-sulphurating treatment

Compared with the single sulphurating treatment, the duplex treatment of nitrocarburizing-sulphurating can more effectively improve the properties of steel such as friction-reducing, wear resistance and anti-scuffing. Under the same processing parameters, the sulphide layers were fabricated on the surface of CrMoCu alloy cast iron by single ion-sulphurating treatment and nitrocarburizing-sulphurating duplex treatment, respectively. Through the analysis of the sulphide, the effect of the nitrocarburizing on the fabrication of the sulphide layer was investigated. And the result shows that the fabrication of sulphide layer is promoted by the nitrocarburizing treatment.

膨润土在废水处理中的应用综述

随着环境保护标准的日益严格，开发新型、廉价、高效的水处理材料也日趋紧迫。首先简要地介绍了非金属矿物材料——膨润土的矿物学特征。这些特征使得膨润土具有许多优良的基本特性，如电负性、离子交换性能等等。如果进一步针对膨润土的一种或者某些特性加以改性，膨润土就非常有可能在实际工程中被广泛应用。其次较为详细地综述了膨润土在废水处理中应用的现状，主要是作为制备吸附剂和絮凝剂的原料。而且，由膨润土改性所制成的吸附剂或絮凝剂对废水中的无机、有机污染物都有较为理想的去除率。最后，对膨润土的应用前景进行了展望。

Does the Youth Corrections System Work? Tracking the Effectiveness of Intervention Efforts With Delinquent Boys in State Custody.

This study adopted a systemic approach to studying intervention efforts with delinquent youth, examining the association between several youth corrections programs and adult criminal outcomes. Two studies were designed to use juvenile and adult court records to evaluate the effectiveness of treatment programs provided to delinquent youth in state custody. The results of Study 1 suggested that court-recorded delinquent charges can be used to estimate delinquency severity. The results of Study 2 presented a discouraging but not entirely unexpected illustration of the effectiveness of intervention efforts among delinquent youth. It was found that time spent in juvenile detention facilities, work programs, and group homes was associated with negative adult criminal outcomes. No links between time spent in youth corrections programs and positive outcomes were identified. Implications for future program evaluation efforts are discussed.
