Research on the social determinants of health has often considered education and economic resources as separate indicators of socioeconomic status. From a policy perspective, however, it is important to understand the relative strength of the effect of these social factors on health outcomes, particularly in developing countries. It is also important to examine not only the impact of education and economic resources of individuals, but also whether community and country levels of these factors affect health outcomes. This analysis uses multilevel regression models to assess the relative effects of education and economic resources on infant mortality at the family, community, and country level using data from demographic and Health Surveys in 43 low-and lower-middle-income countries. We find strong effects for both per capita gross national income and completed secondary education at the country level, but a greater impact of education within families and communities. 相似文献

Methods for smoothed isotonic or convex regression are useful in many applications. Sometimes the shape assumptions constitute a priori knowledge about the regression function, but often the shape is part of the research question. The authors propose tests for monotonicity and convexity using constrained and unconstrained regression splines. The tests have good large‐sample properties and the small‐sample behaviour is illustrated through simulations. Extensions to the partial linear model and the generalized regression model are presented. The Canadian Journal of Statistics 39: 89–107; 2011 © 2011 Statistical Society of Canada 相似文献

The demand for insurance is examined when the insured asset can incur losses that are excluded from insurance coverage. These
losses are negatively correlated with covered losses and hence cannot be treated as background risk. Excluded losses have
strikingly different effects on the demand for insurance than does background risk and lead to a modification of many standard
insurance demand results. A number of new theorems concerning the effects of excluded losses are also presented. Risk-averse
and prudent decision makers reduce their demand for insurance when excluded losses increase in size or riskiness. Excluded
losses are a possible explanation for why many decision makers fail to take up insurance when it is offered. 相似文献

We present a new class of models to fit longitudinal data, obtained with a suitable modification of the classical linear mixed-effects model. For each sample unit, the joint distribution of the random effect and the random error is a finite mixture of scale mixtures of multivariate skew-normal distributions. This extension allows us to model the data in a more flexible way, taking into account skewness, multimodality and discrepant observations at the same time. The scale mixtures of skew-normal form an attractive class of asymmetric heavy-tailed distributions that includes the skew-normal, skew-Student-t, skew-slash and the skew-contaminated normal distributions as special cases, being a flexible alternative to the use of the corresponding symmetric distributions in this type of models. A simple efficient MCMC Gibbs-type algorithm for posterior Bayesian inference is employed. In order to illustrate the usefulness of the proposed methodology, two artificial and two real data sets are analyzed. 相似文献

Defining “political salience” as the “timeliness, frequency, and public prominence of a response to apolitical event,” the author found in a literature review of social work education and practice, 1968–1972, a predominance of social policy and program development content, usually conceptual or analytic in approach. Discussion of practice roles, values, and skills appropriate to the new political realities of thai period were minimal. Part of the reporting gap was caused by publication policy and technology. A more rapid level of information transfer is suggested to assure course and practice material that would be useful in political and organizational terms. 相似文献

Every day, Americans are inundated with advertisements and appeals to purchase the latest mobile technology in the form of smart phones, tablets, and their accompanying applications (apps). Human service organizations (HSOs) across the United States have begun to recognize that apps can provide a valuable resource for individuals and communities by addressing social issues. Additionally, forward-thinking HSOs are aware that apps are a fresh and important way of reaching a rapidly changing, tech-savvy population. But just like the marketplace at large yields a variety of apps that range from useful and engaging to poorly contrived and ineffective, HSOs' foray into app development has achieved mixed results. This report analyzes existing mobile applications available for one specific field of HSO service delivery—suicide prevention—in order to describe what is currently available and to generate beginning guidelines for the development, implementation, and evaluation of new suicide prevention apps for underserved populations. Twenty-seven apps were analyzed and recommendations for HSOs and future research are presented. 相似文献

The purpose of this article is to present a family intervention model to family service providers that builds on previous research in areas of social support and family problem solving. The Family Outreach Model provides a set of strategies for engaging and working with families in five phases of family coping at different points in time in the family's life. The strategies reflect intentional choices by family service providers about both collaborative and directive styles of therapeutic alliance and highlights ways to determine which style best fits with what specific families want and need, depending on the manner of family coping that it is using. Implications for programs and public policy are presented. 相似文献

ABSTRACTChild sexual abuse has the potential to cause distress for the victim across the lifespan. Romantic relationships may be particularly difficult for victims of child sexual abuse. This retrospective study examined differences in adult romantic attachment, sexually compulsive behaviors, and emotion regulation by history of child sexual abuse in a large, nonclinical sample. Those with a history of child sexual abuse reported more attachment anxiety in romantic relationships and engaged in more sexually compulsive behaviors. Overall, males displayed more sexually compulsive behaviors than females regardless of history of sexual abuse. Males with a history of sexual abuse displayed the greatest number of sexually compulsive behaviors. Surprisingly, no differences were observed in emotion regulation or attachment avoidant behaviors by history of child sexual abuse. Future research should seek to replicate current findings and examine emotion regulation difficulties experienced as a result of trauma. 相似文献

ABSTRACTSickle Cell Disease (SCD) is a serious health problem affecting millions around the world. Key to prevention is knowledge about the disease and the reproductive implications. This study explored college students’ knowledge about SCD. Participants included 416 college students at a North Texas campus between October and December 2014. A cross-sectional survey design using an 18-question survey was used. Although most participants had heard of SCD, 21% had never heard of the disease. Furthermore, participants lacked knowledge regarding the differences between the disease and carrier status, prevalence, reproductive implications, prevention, and testing. Findings showed that couples had more knowledge about SCD compared to singles and there were no significant differences between those with children and those without indicating a need for education before they start dating. Most participants had not undergone SCD carrier screening and had no interest in screening. The Universal Prevention approach would be a suitable approach and should be utilized in improving knowledge about SCD. 相似文献
