Seventy‐six fourth‐grade children and their parents participated in a study of the linkages among parental control and positive affect, children's display rule use, and children's social competence with peers. Using observational measures of parental behavior and children's display rule use, it was found that parental positive affect and control were related to children's display rule use (including both positive and negative responses). Moreover, the links between parental affect and control and children's social competence one year later (as rated by teachers and peers) were found to be mediated by children's display rule use. Finally, fathers’ behavior was found to be particularly important in the prediction of children's display rule use. The importance of fathers in children's social and emotional development and the importance of examining multiple parental behaviors are discussed.  相似文献

Rural dwelling elders who experience mental health problems often have difficulty finding help since rural communities often lack adequate mental health service providers. This paper reports on the initial phase of a 5-year, interdisciplinary clinical research study that is testing the effectiveness of providing a home delivered, therapeutic psychosocial intervention, aimed at improving the emotional wellbeing and the quality of life of medically frail elders who live in rural communities. In the early phases of this study, the clinical research team encountered a number of interesting and often unanticipated challenges as it attempted to recruit study participants and provide services to them. In this article, we examine these challenges and share what we have learned so far about providing mental health services to elderly persons living in rural environments.  相似文献

Objectives. In this article we examine political advocacy by nonprofit organizations. Relatively little is known about the types of organizations that participate in advocacy, their characteristics, the issues for which they advocate, and the resources they devote to it. This is especially the case for nonprofits that operate at the state or local level. Methods. Using data from a large survey of Indiana nonprofit organizations, we use logistic and multinomial regression to determine which organizational characteristics relate to participation in varying levels of advocacy. Results. We find that the size of the organization, its access to information and communication technology, its charitable status, and, in some cases, the field of activity in which it operates all help predict nonprofit advocacy. The age of the organization, its reliance on government funding (except when substantial), and its proximity to the state's major economic and political center do not generally help differentiate nonprofits that advocate from those that do not. Conclusions. Our findings suggest that most nonprofits are ambivalent about advocacy. Some do no advocacy at all; many participate in some form of it although it does not constitute their primary purpose or mission; and only a small minority devotes considerable resources to it. However, these patterns differ systematically by type of nonprofit.  相似文献

Objective. This study adds to our knowledge of the naturalization process by considering the impact of political orientations in shaping the pursuit of U.S. citizenship among contemporary Latino and Latina immigrants. Methods. We draw on data from the 1999 Harvard/Kaiser/Washington Post “Latino Political Survey” and use ordered logistic regression analyses to test the effects of political orientations on immigrant naturalization. Results. Political orientations exert a powerful influence on naturalization beyond the traditional sociodemographic determinants. Furthermore, the impact of political orientations on naturalization varies by gender. Conclusions. Naturalization can be induced by stressing the importance of voting and being interested in politics. In addition, Latinas are more likely to pursue naturalization than Latinos and the factors driving their decisions systematically differ from those of their male counterparts.  相似文献

Objective. Much of the empirical work on environmental justice centers on the geographic distribution of potential chronic health risks (e.g., planned toxic releases or treatment storage and disposal facilities). Far less attention has been devoted to the geographic distribution of acute health risks that cause immediate harm. The purpose of this work is to examine environmental justice in terms of potential acute health risks by examining the distribution of serious chemical accidents across diverse subpopulations. Methods. We draw upon 1990 census data for the United States to study the relationship between the racial, ethnic, and economic characteristics of census block groups ( N = 226,398) and the presence or absence of chemical accidents that caused at least one injury, death, or evacuation for the time period of 1990–1996. The data used to map the location of the chemical accidents were obtained from the Environmental Protection Agency's Accidental Release Information Program (ARIP) database. Results. Our results indicate that the acute risk associated with chemical accidents at fixed facilities is greater for individuals living in low–income census block groups, especially when comparisons are made within the counties where the chemical accidents occur. Our results concerning race and ethnicity are less consistent and somewhat weaker. Conclusions. Although these results do not show large and dramatic effects, as have often been found in the study of the social distribution of chronic environmental risk, they do stand as one of a relatively few social analyses of social variation in exposure to acute environmental risk.  相似文献

While social workers are becoming increasingly interested in methods of client empowerment, little attention has yet focused on the links between workers' own power and the services they provide to clients. The authors examine the link between workers' perceptions of their power on the job and perceived service outcomes. Bivariate and multivariate analyses were conducted on survey responses from 591 direct practice social workers in Israel. Results indicate that power perceptions are significantly associated with an array of perceived service outcomes. These findings highlight the relevance of self-efficacy and control theory in understanding social workers' efforts toward effective service delivery. Further, they underscore a need to consider more carefully direct practitioners' own power concerns as they increasingly consider empowerment of their clients.  相似文献

This report describes the current avenues of investment used by provident fund schemes in seven island nations in the Pacific; the returns on these investments; the criteria for their selection; and the governments' guidelines and restrictions on these schemes. New investment guidelines from 1988 to 1992 are summarized and the reasons for them are explained. Limitations on permitted investment avenues are briefly described. The latter part of the report, and its main focus, analyses the problems faced when trying to balance the interests of provident fund members with national interests when selecting investments. The report concludes with some recommendations for solutions to the problems related to limited investment outlets and government restrictions. To gather information for this report, a questionnaire was sent to the provident fund schemes in the Pacific and the available annual reports were analysed. Responses, when received, have been included.  相似文献

The study explicates a competency-based model of contemporary social work management practice and compares this model with frameworks derived from earlier studies. Using a purposive sample of 184 social work managers throughout the country, an exploratory factor analysis yielded twelve sets of competencies required of today's social work manager. A comparison of the present model to earlier management frameworks reveals that substantive changes in the nature, scope, complexity, and priorities assigned to management competencies and skills have transformed the role of the social work manager over the last decade. Implications for social work manager education are reviewed and future research directions are proposed.  相似文献

In times of shrinking resources within the social services, collaboration is being promoted as a more efficient way of meeting the needs of children and families. A study of a children's initiative collaborative developed to address the problems of children is reported. The authors present and use an evaluation framework which incorporated the dimensions of context, process, and outcomes of collaboration. The findings, based on the initial two years of collaborative effort, suggested the membership of the group and the process and structure governing the group's operations impacted the process and outcomes of the collaboration.  相似文献
