Children, youth, and families served by child welfare professionals should be provided with services that are reasonably well-supported by scientific evidence, when such knowledge exists. A number of clearinghouses and databases have been created in recent years that list a wide array of child welfare, mental health, substance abuse, family, and educational services, provide a critical appraisal of the levels of evidence available for each such service, and rates this evidence. Some interventions are said to possess strong evidence of their effectiveness and can be called research supported. Others are poorly researched and some have been shown to actually be harmful. This article describes a summary of these major databases and clearinghouses evaluating programs and practices for potential use in child welfare. Links are provided to assist child welfare professionals in locating these research supported psychosocial interventions. 相似文献

Scan-derived landmarks locations and surface shapes are more and more used, but there is no commonly accepted protocol for evaluating the accuracy of these measurements. Therefore we propose a protocol for evaluating the accuracy of surface shape and the repeatability of scan-derived landmark locations. According to existing Japanese and German domestic standards, we propose to use an artefact (e.g. sphere with diameter of about 120 mm) calibrated very accurately for evaluating the accuracy of scanner-systems. For evaluating the repeatability of landmark locations, we propose to use an anthropomorphic dummy with landmark locations premarked. These test objects are measured by a 3D body scanner to be evaluated. Evaluation parameters such as trueness, precision, and repeatability are calculated from the measured data. A round-robin test was conducted in six different institutes using 17 body/head/foot scanners produced by eight companies. The purposes of the roundrobin test were to evaluate the availability of test objects to different body scanners, and to examine the measurement locations of test objects and quality parameters to be reported. As a result, the proposed test objects could be measured and the data exported by all scanner systems except one, which could not export the ball measurement. For a comparative purpose, a figure of measured surface might be useful. 相似文献

The National Association of Social Workers requires social workers to obtain continuing education (CE) after they receive their social work degrees. A large and profitable industry that has emerged catering to this need for CE that is particularly focused on the needs of licensed social workers. Quality control mechanisms in place to monitor the content and delivery of CE approved by the field of social work is relatively lax, and as a result a considerable number of social work CE programs convey content that can be labeled as pseudoscientific. We provide illustrations of currently approved social work CE courses that provide training in a variety of bizarre and unsupported assessment methods and treatments that are pseudoscientific. 相似文献

Papua New Guinea (PNG) faces enormous health challenges and information concerning how to allocate limited health resources efficiently is lacking. This article finds that geographical location is important in achieving higher efficiency scores. In addition, it compares efficiency scores against a range of quality indicators. The results demonstrate that different conclusions are reached when efficiency scores are assessed in the context of broader health system objectives. Analyses of this kind can provide valuable information to policy‐makers in lower‐income countries. 相似文献

The philosophical framework of strong relationality has gained greater attention in scholarship and yet empirically testing models built on this important framework are rare. The present study tests predictions made by the Strong Relationality Model of Relationship Flourishing (SRM), which centers on the role of Ethical Responsiveness for relationship health. In doing so, we introduce common fate modeling as a methodological approach for strong relationality research. We used longitudinal data from 1512 couples collected as part of the German longitudinal panel study of families. Results support the Strong Relationality Model's prediction that Ethical Responsiveness (as measured by perceived partner support) positively alters the impact of stress on Gratitude-Recognition (elements of the Responsible Action domain of the SRM), which then increases couples' intimacy (an element of the Relational-Connectivity domain of the SRM). Recommendations for clinical assessment and intervention are given as well as recommendations for future research on the Strong Relationality Model. 相似文献

Limited human capital investment is a common characteristic of low‐income countries despite the fact that estimated returns to educational investment in low‐income countries are generally higher than those in high‐income countries. Empirical evidence suggests that income and credit constraints can only account for a part of this underinvestment. Recent experimental evidence shows that families' misperceptions about the returns to education play a role in their low‐investment levels. This paper builds a heterogeneous‐agent model of human capital and growth that incorporates an adaptive learning mechanism to capture the way agents form perceptions about returns to education. We find natural conditions guaranteeing existence of stable equilibria. Along transition paths, agents' misperceptions about returns to education depress realized returns, which serves to reenforce and perpetuate low human‐capital investment. If human capital investments have both private and public returns, we find multiple stable equilibria, including those which are characterized by low investment and low returns.
