In this article, we predict and find that self-perceptions of environmentalism are changed by subtle manipulations of context and, in turn, affect environmental behavior. In Study 1, we found that people exhibit greater positive assessments of their environmental behaviors (1) in the context of denying harm to the environment than in the context of claiming to help the environment, and (2) in situations where behaviors are evaluated subjectively than in situations where behaviors are evaluated more objectively. In Study 2, we explored the relationship between self-perceptions of environmentalism and environmental behaviors. Our data suggest that environmentally friendly behaviors may be promoted by leading people to perceive themselves as good environmentalists.  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

Abstract

Objective: To identify human papillomavirus (HPV) infection and HPV vaccine–related attitudes among college-aged women and the relationship between HPV vaccine uptake and subsequent sexual behaviors. Methods: PubMed, MEDLINE, CINAHL, and Google Scholar searches were performed from 2006, the date after the first HPV vaccine became available, to present. Results: Of the 13 studies identified, most were cross-sectional. College-aged women saw HPV infection as serious and had positive attitudes toward the HPV vaccine. Barriers (ie, cost, lack of insurance coverage) existed that prevented women from obtaining the vaccine and many women did not see themselves at risk for HPV. The vaccine uptake rate, although increasing, has been slow. Conclusion: College-aged women in the United States may need unbiased information about HPV and HPV vaccine. Studies that focus on risk perception and the relationship between knowledge, attitudes, vaccine uptake, and sexual behaviors are needed to inform interventions and public health programs.  相似文献

This article presents the findings of a case study examining the relationship between social capital and individual participation in collective action on a Caribbean island recovering from devastation inflicted by Hurricanes Ivan and Emily. Using data drawn from 114 residential surveys on the island of Carriacou, Grenada, over the summer of 2006, we empirically test social capital as a predictor of individual participation in both formal and informal civic events. In addition, we further the theoretical development of the concept of social capital by independently testing the relationships between its multiple dimensions, specifically social networks; interpersonal trust; and norms of reciprocity. We find that associational membership and age are the two strongest predictors, while interpersonal trust, gender, and marital status are also significant. Our path analysis reveals that there is not a significant direct effect between associational membership and interpersonal trust, suggesting that the two dimensions may have independent, yet complementary, influences. This study sheds light on factors influencing citizen participation in “civic” forms of collective action in a developing region of the world, while demonstrating the multidimensional nature of social capital.  相似文献

The admissibility of testing procedures is examined when the loss function used is an increasing function of the p-value rather than the standard 0–1 loss. It is shown that the class of admissible procedures using the new approach is a subset of the class of admissible procedures using the 0–1 loss.  相似文献

Adaptive sampling without replacement of clusters   总被引:1,自引:0,他引:1  
In a common form of adaptive cluster sampling, an initial sample of units is selected by random sampling without replacement and, whenever the observed value of the unit is sufficiently high, its neighboring units are added to the sample, with the process of adding neighbors repeated if any of the added units are also high valued. In this way, an initial selection of a high-valued unit results in the addition of the entire network of surrounding high-valued units and some low-valued “edge” units where sampling stops. Repeat selections can occur when more than one initially selected unit is in the same network or when an edge unit is shared by more than one added network. Adaptive sampling without replacement of networks avoids some of this repeat selection by sequentially selecting initial sample units only from the part of the population not already in any selected network. The design proposed in this paper carries this step further by selecting initial units only from the population, exclusive of any previously selected networks or edge units.  相似文献
