Economic strengthening interventions may increase income, assets, and food security. Donors and implementers see the potential for improvements in child well-being. This article presents lessons learnt from the implementation of two economic strengthening interventions. It finds missed opportunities with regard to child nutrition, and recommends: (1) integrating economic strengthening interventions with complementary development activities; (2) deep formative assessment to inform programme design; and (3) the use of community-based feedback loops. Development practitioners, funders, policymakers, and researchers must take every opportunity to improve the lives of children as young as possible to build healthy families, communities, and nations. 相似文献

The Physician Orders for Life-Sustaining Treatment (POLST) Paradigm is designed to improve end-of-life care by converting patients' treatment preferences into medical orders that are transferable throughout the health care system. It was initially developed in Oregon, but is now implemented in multiple states with many others considering its use. An observational study was conducted in order to identify potential legal barriers to the implementation of a POLST Paradigm. Information was obtained from experts at state emergency medical services and long-term care organizations/agencies in combination with a review of relevant state law. 相似文献

An important research finding is that parent–adolescent communication is related to adolescent adjustment. However, when using self-report measures with multiple reporters, adolescent and parent reports do not correlate highly, and within-rater reports correlate higher than cross-rater reports. This limits the utility of traditional methods of aggregation across raters. The present study used canonical correlation to examine if and how mother and adolescent reports for communication and problem behaviors are related. With reports from 161 adolescents and their mothers, the results indicated that the relationship between mother and adolescent reports differed by problem behavior area. Within-rater reports dominated the dimensions for communication related to aggressive behaviors. For anxious/depressed behaviors, both mother and adolescent reports contributed to the dimensions, with 1 dimension reflecting opposite perceptions of communication and adjustment by mothers and adolescents. 相似文献

Surveys with 94 administrators of supervised visitation programs, 51 family court judges, and 40 administrators of child protective services agencies provide a national picture of supervised visitation services, their utility, and areas of unmet need. Although the programs are perceived to fill an important need, they struggle to survive financially, particularly those that handle family court cases. In addition, because many programs operate without adequate access to the assessment and treatment services that some families need, judges frequently want visitation supervisors to assist them in determining suitable custody and visitation arrangements, a role that supervised visitation programs do not feel is appropriate. Many different types of entities provide effective supervised visitation services; many different service formats work. Architects of new programs should fashion services that use local resources to maximum advantage. 相似文献

This article identifies and describes the development of three parallel streams of literature about network theory and research: social network analysis, policy change and political science networks, and public management networks. Noting that these traditions have sometimes been inattentive to each other's work, the authors illustrate the similarities and differences in the underlying theoretical assumptions, types of research questions addressed, and research methods typically employed by the three traditions. The authors draw especially on the social network analysis (sociological) tradition to provide theoretical and research insights for those who focus primarily on public management networks. The article concludes with recommendations for advancing current scholarship on public management networks. 相似文献

Three commercially available integrated rapid DNA instruments were tested as a part of a rapid DNA maturity assessment in July of 2018. The assessment was conducted with sets of blinded single-source reference samples provided to participants for testing on the individual rapid platforms within their laboratories. The data were returned to the National Institute of Standards and Technology (NIST) for review and analysis. Both FBI-defined automated review (Rapid DNA Analysis) and manual review (Modified Rapid DNA Analysis) of the datasets were conducted to assess the success of genotyping the 20 Combined DNA Index System (CODIS) core STR loci and full profiles generated by the instruments. Genotype results from the multiple platforms, participating laboratories, and STR typing chemistries were combined into a single analysis. The Rapid DNA Analysis resulted in a success rate of 80% for full profiles (85% for the 20 CODIS core loci) with automated analysis. Modified Rapid DNA Analysis resulted in a success rate of 90% for both the CODIS 20 core loci and full profiles (all attempted loci per chemistry). An analysis of the peak height ratios demonstrated that 95% of all heterozygous alleles were above 59% heterozygote balance. For base-pair sizing precision, the precision was below the standard 0.5 bp deviation for both the ANDE 6C System and the RapidHIT 200. 相似文献
