An exploratory qualitative study was conducted to explore how child welfare administrators use research evidence in decision-making. Content analysis revealed that a cultural shift toward evidence-based practice (EBP) is occurring in Canadian child welfare organizations and multiple types of evidence inform policy decisions. Barriers to using evidence include individual, organizational, and environmental factors. Facilitating factors include the development of internal champions and organizational cultures that value EBP. Integrating research into practice and policy decisions requires a multifaceted approach of creating organizational cultures that support research utilization and supporting senior bureaucrats to use research evidence in policy development.  相似文献

In order to compute the log-likelihood for high dimensional Gaussian models, it is necessary to compute the determinant of the large, sparse, symmetric positive definite precision matrix. Traditional methods for evaluating the log-likelihood, which are typically based on Cholesky factorisations, are not feasible for very large models due to the massive memory requirements. We present a novel approach for evaluating such likelihoods that only requires the computation of matrix-vector products. In this approach we utilise matrix functions, Krylov subspaces, and probing vectors to construct an iterative numerical method for computing the log-likelihood.  相似文献

The current paper explores recent changes in food insecurity among adolescents and determine if food security concerns are associated with poorer wellbeing. Data were collected as part of two nationally representative surveys of the health and wellbeing of high-school students in New Zealand in 2007 and 2012. In 2012, 11% of young people reported food security concerns often or always, with 33% reporting food security concerns occasionally/sometimes. The prevalence of food security concerns at both frequencies increased significantly from 2007 (8% and 28%, respectively). Young people with food security concerns were more likely to report poor indicators of health and wellbeing, including truancy, poor general health, mental health concerns and obesity. Our findings highlight the growing concerns of food insecurity reported by adolescents in New Zealand. Interventions that address food security for families may provide a tangible means of promoting the healthy development of children and young people.  相似文献

Mubangizi BC, Gray M. Putting the ‘public’ into public service delivery for social welfare in South Africa Int J Soc Welfare 2011: 20: 212–219 © 2010 The Author(s), International Journal of Social Welfare © 2010 Blackwell Publishing Ltd and the International Journal of SocialWelfare. The privatisation of some essential services in South Africa has raised severe difficulties for those for whom the idea of fees for services is quite foreign and who, in any case, cannot afford to pay for services. The government has developed several initiatives to educate people about the need to pay for services provided by local government, the largest of which was the Masakhane fees‐for‐services campaign. This article describes two recent initiatives that seek to engage local citizen participation, namely, Integrated Development Plans and izimbizo (or traditional forums). These are examined along with the challenges faced by local government in promoting citizenship participation in service delivery within a decentralised system of governance. The article concludes with some recommendations on how citizen participation can be enhanced so as to make the ‘public’ visible in public service delivery and thus improve social welfare services.  相似文献

Abstract

Panic disorder is characterized by recurrent, sudden, often unprovoked attacks of intense, diffuse autonomic discharge accompanied by severe anxiety as distinguished from ordinary generalized anxiety. Recent research indicates a biochemical abnormality that predisposes some individuals to the disorder, which generally begins in young adulthood and affects women twice as frequently as men. Untreated panic disorder follows a chronic, fluctuating course. Complications include hypochondriasis, anticipatory anxiety, phobic avoidance and agoraphobia, abuse of alcohol and sedative drugs, and depression.

Diagnosis is complicated by patients' complaints of physical rather than emotional symptoms. Workups can be avoided if the physician considers the diagnosis in apparently healthy young adults who present with episodic cardiac, gastrointestinal, neurologic, and/or respiratory symptoms. The physician needs to be able to distinguish the symptoms of panic disorder from those of ordinary anxiety and also to rule out medical conditions that mimic panic disorder.

Neither conventional benzodiazepines nor psychotherapy alone is very effective in stopping panic attacks, but alprazolam, imipramine, and phenelzine are all highly effective. Alprazolam has fewer troublesome side effects, but patience and perseverance are necessary to reach therapeutic levels with all three drugs. Inadequate dosage is the most common cause of treatment failure. Most patients do well once their attacks are controlled and do not require close follow-up. Patient education is an important part of long-term management because relapses are common.  相似文献

Dual-degree programs in public health and social work continue to proliferate, yet there has been little research on master’s of social work (MSW)/master’s of public health (MPH) graduates. The purpose of this study was to describe and better understand the self-reported professional experiences, identities, roles, and outcomes associated with 1 group of graduates from an established MSW/MPH program. A 57-question electronic survey was administered to 214 alumni in 2010; the response rate was 71.4% (n = 153). Findings provide a snapshot of public health social work alumni experiences, including diverse employment opportunities, high career satisfaction, and a strong sense of reported public health and social work integration in the workplace.  相似文献

This study investigated the independent impact of child sexual abuse on five dimensions of adulthood parenting after controlling for other forms of childhood adversity in a predominantly African-American sample of mothers receiving public assistance (N = 483). An analysis of data previously collected as part of the Illinois Families Study Child Well-Being Supplement was conducted to address these questions. Data were analyzed using hierarchal multiple regression. Childhood sexual abuse survivors reported significantly lower rates of parental warmth, higher rates of psychological aggression, and more frequent use of corporal punishment than mothers who had not experienced childhood sexual abuse. These effects, however, were nonsignificant when sociodemographic factors and other forms of childhood adversity were considered. Implications for future research are provided.  相似文献

College obesity is increasing, but to the authors' knowledge, no researchers to date have evaluated risk factors in this population. OBJECTIVE: The authors assessed whether abnormal eating perceptions and behaviors were associated with overweight in college students. PARTICIPANTS AND METHODS: A sample of undergraduates (N = 4,201) completed an online survey containing demographic questions and the Eating Attitudes Test-26 (EAT-26) questionnaire. The authors stratified participants into normal-weight and overweight/obese groups and evaluated physical activity, EAT-26 score, purging behaviors, and answers to selected overweight screening questions on the basis of body mass index. A modified EAT-26 score of > or = 11 was associated with overweight (p = .016). RESULTS: Compared with normal-weight peers, overweight participants displayed an increased fear of bingeing, preoccupation with food, desire to be thinner, and engagement in dieting behavior. Mean body mass index also increased with age and physical inactivity (p < .001). CONCLUSIONS: Because physical inactivity, disordered eating perceptions, and disordered behaviors are associated with increased rates of overweight and obesity, identification of these risk factors in obese youths may increase understanding of weight loss barriers and facilitate the treatment of adolescent obesity.  相似文献
