This study aims to contribute to the body of knowledge about post-adoption functioning of international adoptees by examining patterns of anxiety among young children adopted from China by Australian families. The study had two objectives: to examine anxiety in children adopted from China comparing this sample to available normative data and to examine the associations among child anxiety and child (e.g., age at adoption) and parent (e.g., age, education level) factors. Parents of 59 children adopted from China completed online a number of measures of child anxiety, temperament, and parent psychological well-being. Results indicated a high prevalence of anxiety symptoms among the adopted children when compared with available data from normative samples, particularly related to separation contexts. A number of factors, including inhibited temperament and younger age of parents, were associated with child anxiety. Clinical and research implications are discussed.  相似文献

This study evaluates the effectiveness of an arts-based educational program, Basic Reading Through Dance. Basic Reading Through Dance is a 20-session, curriculum-based reading intervention for first-grade students developed by Whirlwind, a not-for-profit organization. There were a total of 721 first-grade students from Chicago public schools who participated in the study, with 328 students from 6 schools receiving the program and 393 students from 9 schools serving as controls. The program was designed to improve reading skills, as assessed by the PhonoGraphix Test, such as code knowledge (alphabet sounds) and phoneme segmentation (separating letter sounds within spoken words). Results suggest that the students who participated in the program improved significantly more than control students on all reading skills that were assessed.  相似文献

E-mail: s.a.webb{at}sussex.ac.uk Summary This article argues that in a complex socio-political world,social work ethics needs to re-cast the moral identity of thesocial worker in terms of virtue ethics. We review virtue theory'sAristotelian foundations and criticisms of Kantian and utilitariantheory and show how they apply to social work. Subsequentlywe offer an account of a virtue-based social work that questionsthe validity of several models of practice currently fashionable.Virtue theory emphasizes the priority of the individual moralagent who has acquired virtues commensurate with the pursuitof a revisable conception of the good life—the well-beingof all in a defined community. The virtues are the acquiredinner qualities of humans—character—the possessionof which, if applied in due measure, will typically contributeto the realization of the good life or ‘eudaimonia’.The role of the virtuous social worker is shown to be one thatnecessitates appropriate application of intellectual and practicalvirtues such as justice, reflection, perception, judgement,bravery, prudence, liberality and temperance. This ‘self-flourishing’worker, in bringing together the capacity for theoretical andpractical action makes possible a hermeneutic or interpretivepraxis best appraised in dialogue with fellow-practitionersand clients. With a social work remit increasingly routinizedby accountability, quality control and risk management thereis an emphasis on regulation and duties. This has produced aculture of following approved or typical processes resultingin defensive forms of social work wholly uncongenial to thedevelopment of human qualities likely to promote social workers'engagement in critique and revision of what counts as best practice.In sum, our core proposition is that social work practice andeducation, to fit an unpredictable, non-linear world, shoulddevelop means by which professionals nurture the virtues. Thiswould reflexively enhance social work itself.  相似文献

Five-Hundred Life-Saving Interventions and Their Cost-Effectiveness   总被引:42,自引:0,他引:42  
We gathered information on the cost-effectiveness of life-saving interventions in the United States from publicly available economic analyses. "Life-saving interventions" were defined as any behavioral and/or technological strategy that reduces the probability of premature death among a specified target population. We defined cost-effectiveness as the net resource costs of an intervention per year of life saved. To improve the comparability of cost-effectiveness ratios arrived at with diverse methods, we established fixed definitional goals and revised published estimates, when necessary and feasible, to meet these goals. The 587 interventions identified ranged from those that save more resources than they cost, to those costing more than 10 billion dollars per year of life saved. Overall, the median intervention costs $42,000 per life-year saved. The median medical intervention costs $19,000/life-year; injury reduction $48,000/life-year; and toxin control $2,800,000/life-year. Cost/life-year ratios and bibliographic references for more than 500 life-saving interventions are provided.  相似文献

A Simulated Annealing Approach to Communication Network Design   总被引:1,自引:0,他引:1  
This paper explores the use of the meta-heuristic search algorithm Simulated Annealing for solving a minimum cost network synthesis problem. This problem is a common one in the design of telecommunication networks. The formulation we use models a number of practical problems with hop-limit, degree and capacity constraints. Emphasis is placed on a new approach that uses a knapsack polytope to select amongst a number of pre-computed traffic routes in order to synthesise the network. The advantage of this approach is that a subset of the best routes can be used instead of the whole set, thereby making the process of designing large networks practicable. Using simulated annealing, we solve moderately large networks (up to 30 nodes) efficiently.  相似文献

ABSTRACT: We compare changes in the effect of child support payments on the educational attainment of children age 16 to 19 before and after passage of the Child Support Enforcement Amendments of 1984, which strengthened enforcement of child support obligations in the United States. Using 1979, 1984, and 1988 Current Population Survey data, we hypothesize and find a decline in the positive effect of child support between 1984 and 1988 that exceeds any earlier decline. Instrumental variables estimates provide additional evidence consistent with the idea that child support serves as an indicator of unobservable characteristics of noncustodial fathers who pay support.  相似文献

This study investigates the relationship between the carbon extractive sector in Canada and renewable energy development. Specifically, it examines the strategies employed by Canadian carbon‐capital firms to shape and control alternative energy and considers if we are witnessing signs of “transition capture” as some oil, gas, and coal firms invest in a gradual shift toward “climate capitalism.” I investigate first, investments by large Canada‐based fossil fuel companies in renewable energy and second, interlocking directorate relations between the fossil fuel sector and the renewables industry. Findings suggest the possibility of a long‐term strategic orientation toward a climate capitalist model of development by some carbon‐capital firms; however, this alignment remains highly tentative, with evidence pointing to an industry that is largely without plans for energy transition.  相似文献

Rural dwelling and older age are both associated with a higher risk of social exclusion, with accessibility identified as having an important facilitating role. The interactions between transport-related exclusion and older age, particularly in a rural context, are considered though analysis of quantitative and qualitative data collected from over 900 older persons living in rural areas of Southwest England and Wales. Although few respondents reported feeling excluded within their communities, more reported difficulties in accessing specific necessary and discretionary activities, including specialist hospitals and cinemas. Analysis revealed that car availability is not a strong indicator of overall inclusion, although non-availability was important in limiting access to particular types of location. It is concluded that the relatively short travel distances required to access community activities was a key factor in the high levels of community inclusion. However, the car-dependent nature of travel overall means that there is a rising risk of mobility-related exclusion in rural areas, particularly amongst the oldest old. Greater consideration needs to be given to more formalised lift-giving as a transport solution, along with greater attention to mobility needs by sector-specific service providers, such as the health sector.  相似文献

Current research on the behavioural impacts of social movements tends to focus on their influence on those most intensely involved. Consequently it overlooks the impacts that social movement organisations might have on those outside the activist ghetto. To begin to address this gap in the literature, this article examines the relationship between contact with environmental organisations and public attitudes and behaviour. Monitoring the electricity use of 72 households has facilitated analysis of its association with their environmental attitudes and contact with environmental organisations. Although standard statistical approaches fail to uncover a relationship between contact with environmental organisations and attitudes and behaviour, a deductive blockmodelling approach tells a different story. Low household electricity use is associated with households sharing pro-environmental attitudes and contact with environmental organisations. High energy use is associated with households not sharing any of these; and moderate energy use is associated with a moderate degree of sharing. Our findings reveal the need for systematic studies of environmental movement organisations' impact on the public's pro-environmental behaviours.  相似文献
