Courts resolving child support cases involving separated, divorced, and non‐marital children are charged with defining responsibility for health care coverage for the children under that order. This article explores historical and current medical child support requirements under Title IV‐D of the Social Security Act—the national child support enforcement (“IV‐D”) program. It analyzes legal requirements and policy recommendations, and provides a practical tool judges may use to determine whether health care coverage available to either or both parents is appropriate—that is, comprehensive, accessible, and affordable.  相似文献

This article proposes bottom-up learning as a normative framework for international NGOs. It explores the common but often unacknowledged disparity between organisational values and mission versus actual practice. The first section of the paper raises the question of organisational learning disorders followed by an exploration of learning organisations and bottom-up learning in particular. A section briefly summarising positive developments in the field is followed by discussions of organisational barriers and possible mitigation techniques. The paper closes with a challenge for international NGOs to take a closer look at their learning capabilities with a view to improving service to communities in need.  相似文献

Mainstream criminology still tends to focus on gender as a control variable, ignoring the different pathways to crime followed by males and females. This leaves us with knowledge that we already have—males commit more criminal and delinquent acts than do females, but little information about the similarities and differences between men and women who commit crimes. On the other hand, feminist approaches tend to do one of two things: deal with girls and women only or deal with women and men separately to illuminate the differences. In this paper, we examine articles in three major journals, Criminology, Justice Quarterly, and Journal of Research in Crime and Delinquency, to explore the ways that gender is treated in mainstream criminology journals. Then, we will discuss the implications this has for feminist criminology.  相似文献

We evaluate the cost‐effectiveness of two early childhood interventions that use instructional coaching and parent coaching as levers for improvement. The study design allows us to compare the individual effects of each intervention as well as their combined effect on student outcomes. We find that teachers receiving instructional coaching improve their use of evidence‐based instructional practices, while families receiving parent coaching show increases in numerous responsive parenting behaviors associated with positive child outcomes. Both interventions demonstrate positive impacts on students, but only parent coaching shows statistically significant effects across a range of student outcomes. Instructional coaching alone is substantially less costly and may therefore be the most cost‐effective of the three treatment conditions; however, small sample sizes limit our ability to reach definitive conclusions. Policy simulations suggest that implementing these interventions could raise the overall cost‐effectiveness of Head Start by at least 16 percent.  相似文献

This study presents a series of 16 carriers of hemoglobin S (HbS) who died during various circumstances. Many of the cases were associated with mild to moderate exertion. The onset and/or duration of symptoms varied from a few minutes to several hours with many displaying a prolonged lucid interval with stable vital signs. Despite seeking medical treatment, sickle cell trait-related micro-occlusive crisis was never considered in the differential diagnosis. Several cases were associated with sudden death. In those deaths which were delayed, high anion gap and uncompensated metabolic acidosis were typical and were not heat related. Also characteristic were large increases in creatine kinase, alanine aminotransferase, and aspartate aminotransferase along with myoglobinemia. Although the antemortem diagnosis of rhabdomyolysis was made, the underlying cause was never deduced by the clinicians. The sickling found at autopsy is not always a postmortem artifact, and in the right circumstances can be diagnostic.  相似文献

This study explored factors associated with a lifetime history of domestic violence and sexual assault in a sample of welfare recipients in Illinois. Results indicate that childhood exposure to domestic violence is a risk factor for both sexual assault and domestic violence victimization, but that childhood physical abuse is only a risk factor for domestic violence. Increased education and employment skills and having more children were also risk factors for domestic violence victimization. Domestic violence was significantly associated with depression, while sexual assault was associated with low social support and a greater perceived need for mental health services. Frequent alcohol and drug use were not associated with either type of victimization. Research implications are discussed.  相似文献
