Abstract

An increasing interest in positive youth development has led to the creation and expansion of programs and initiatives related to youth involvement and engagement. This article focuses on the Community Development for Healthy Children initiative, which envisions making Kansas the best state in the nation in which to raise a child. The initiative includes three primary strategies: A multi-media campaign; technical assistance and support to local communities; and mini-grant opportunities. The paper provides examples of activities from across the state that promote youth involvement. Outcomes across four areas are examined, and the benefits and challenges of this initiative are also discussed.  相似文献

ABSTRACT

The Americans With Disabilities Act of 1990 (ADA) protects students wth disabilities from discrimination by academic and professional programs in higher education. A student with a disability cannot be denied admission to an educational program because of his or her disability if the student is otherwise qualified. This means that a student with a disability who is qualified for an academic or professional educational program cannot be denied admission to a program based solely on the student&s disability. This educational requirement mandated by the ADA applies to all educational fields including social work education. The purpose of this study was to explore how social work programs are dealing with these requirements in their admission and academic accommodation procedures. Twelve social work programs located in the mid-western United States participated in the study. Representatives of each of these programs were given an in-depth interview focusing on their admissions process, academic accommodations, and general topics related to social work education and disabilities. All programs taking part in the research were accredited by the Council on Social Work Education (CSWE). The CSWE is the national accreditation body for social work education within the United States.  相似文献

Despite the wide range of resources that traverse social networks, social exchange research has focused on only a narrow subset. Notably, prior social exchange research has not considered resources like information that have the capacity to diffuse through networks. The current study investigates how differences between the standard social exchange resource and an information-type resource affect the advantage provided by one's network position. Results of a laboratory experiment support predictions and offer two new insights to the foundations of positional advantage: (1) the location of advantageous positions in a network differs by resource characteristics, and (2) only in particular situations is a single position able to experience high levels of both power and exchange frequency.  相似文献

This study tested a series of models predicting household expectations of participating in hurricane hazard mitigation incentive programs. Data from 599 households in Florida revealed that mitigation incentive adoption expectations were most strongly and consistently related to hazard intrusiveness and risk perception and, to a lesser extent, worry. Demographic and hazard exposure had indirect effects on mitigation incentive adoption expectations that were mediated by the psychological variables. The results also revealed differences in the factors affecting mitigation incentive adoption expectations for each of five specific incentive programs. Overall, the results suggest that hazard managers are more likely to increase participation in mitigation incentive programs if they provide messages that repeatedly (thus increasing hazard intrusiveness) remind people of the likelihood of severe negative consequences of hurricane impact (thus increasing risk perception).  相似文献

Total quality management (TQM) has been thrust into the psyche of corporate America. TQM is not a new phenomena. Introduced in the early fifties to Japanese managers by an American management expert, it served to make Japan an international economic leader. U.S. companies have generally had little international competition. They now recognize he formidable challenge that quality based companies represent and are striving to replicate these successes. To do so will be to remain competitive. To discount the impact of TQM initiatives could spell economic disaster. Employee assistance program (EAP) management is modeled after American management principles. EAPs are also now having to compete for market share in ways for which they were never prepared. The TQM initiatives currently being implemented in many companies may be applied equally well to EAPs. This article presents an overview of the TQM principles formulated by W. Edwards Derning. The article also attempts to critically analyze some of the areas that have been problematic in EAP management. Further, it examines how TQM initiatives could serve to ameliorate some of these problems and lend additional impetus to the competitiveness of employee assistance programs with other behavioral health care service delivery and cost management programs.  相似文献
