This study examined the impacts of intimate partner aggression by female Vietnam veterans and their male partners on their
children’s behavior problems (N = 100 children). Veteran and partner psychological distress were also examined as potential mediators of these relationships.
Results indicated that physical and psychological aggression perpetration by both the female veteran and the male partner
was associated with child behavior problems. Contrary to expectations, psychological distress in the veteran and partner was
not associated with child behavior problems and did not mediate the effects of physical and psychological aggression on this
outcome. 相似文献

Vetting those who work with children and vulnerable adults is an emotive topic and one which can prove a challenging area for employers. The legitimate interest that parents, carers and employers have in screening those charged with the care of others can be in direct conflict with the most fundamental principles of economic freedom and employees’ human rights. The desire to balance these conflicting objectives is at the heart of the Safeguarding Vulnerable Groups Act 2006, which introduces what is being heralded as the most inclusive and comprehensive vetting and barring system to date. The changes dramatically widen the scope of workers who are subject to vetting and barring processes, covering employees, volunteers and contractors in the education, care and health industries, and affecting some 11.3 million people in the UK. This new scheme is of particular relevance and importance to schools and other educational institutions, who will be directly affected by the changes. This article will examine the practical employment implications of the new regime and the new obligations that the Vetting and Barring Scheme creates for both employers and employees. 相似文献

Current challenges in medical practice, research, and administration demand physicians who are familiar with bioethics, health law, and health economics. Curriculum directors at American Association of Medical Colleges-affiliated medical schools were sent confidential surveys requesting the number of required hours of the above subjects and the years in which they were taught, as well as instructor names. The number of relevant publications since 1990 for each named instructor was assessed by a PubMed search. In sum, teaching in all three subjects combined comprises less than two percent of the total hours in the American medical curriculum, and most instructors have not recently published articles in the fields they teach. This suggests that medical schools should reevaluate their curricula and instructors in bioethics, health law, and health economics. 相似文献

When policies incentivize voluntary activities that also take place in the absence of the incentive, it is critical to identify the additionality of the policy—that is, the degree to which the policy results in actions that would not have occurred otherwise. Rebate programs have become a common conservation policy tool for local municipalities seeking to retrofit residential properties with efficient appliances. This research evaluates whether such rebates can be cost‐effective means for water utilities to promote water conservation. A unique database is developed that combines water‐use data over a three‐year period for all households that participated in a utility's high‐efficiency toilet (HET) rebate program, water‐use data for a matched sample of neighbors who did not receive a rebate, and a survey of rebate participants. Difference‐in‐differences models indicate that installation of an HET reduces household water consumption by approximately 7 percent. While installation of an HET appears to be an effective means for achieving household reductions in water consumption, our results also suggest that the rebate program is a much less effective means for achieving household reductions in water consumption. Specifically, the rebate program is found to provide limited additional water savings beyond what would have occurred naturally and is responsible for only 37 percent of the total water reduction attributable to the installation of HETs over the study period. © 2013 by the Association for Public Policy Analysis and Management. 相似文献

Coalitions have been critical for the reemergence of democracy and stability in Uruguay and Chile. Where do they come from? Why are they successful? To explore the role of history and ideologies in the formation and successes of two leftwing coalitions, Uruguay’s Frente Amplio (Broad Front) (FA) and Chile’s Concertación por la Demcracia (Concertación), the author traveled to South America. In Montevideo and Santiago, she spoke with professors and politicians, government officials and former Presidents. This essay will introduce the Uruguayan and Chilean political party systems, discuss how they have dealt with crimes committed by the dictatorships (1973–1990), and highlight the significance of the two coalitions. It will use the term “left” to designate parties which favor egalitarianism and statism, and claim to speak for the people, especially the underprivileged; the term “right” for those which favor liberty, individual initiative, equality of opportunity, and limited government. 相似文献

Household‐level interview data from a probability sample survey conducted in the northeastern Ecuadorian Amazon in 1990 are used to examine the determinants of income and assets among migrant farmers in the agricultural frontier. Multivariate analysis indicates that size of plot owned, proximity to markets, duration of residence, quality of soil, receipt of technical assistance, off‐farm employment and initial wealth positively influence current household income and wealth. More land in cattle pasture is also associated with higher status. Some settlers are prospering relative to others despite variable soil quality, unsustainable land uses, geographic isolation, apparent scarcity of labor, and lack of supportive infrastructure. The article closes with a discussion of implications for policies to assist small farmers, with some consideration of the potential ecological consequences of farmers’ activities. 相似文献
