This study explores underlying assumptions about board development practices in nonprofit governance. Specifically, a model was developed to determine if using recommended recruitment, board member orientation, and evaluation practices resulted in more competent board members and if the presence of these board members led to better board performance. The sample consisted of 1,051 survey responses from CEOs and board chairs representing 713 credit unions. As member‐benefit nonprofit organizations, credit unions rely almost exclusively on voluntary board members in an oversight capacity. Results support the contention that board development practices lead to more capable board members, and the presence of these board members tends to explain board performance. The study advances the understanding of nonprofit board development practices by further defining the concept and proposing an empirically tested assessment strategy. Furthermore, the findings support using specific recruitment practices that should strengthen nonprofit boards. 相似文献

Over the past two decades the sexual content on television has increased in frequency and explicitness but has seldom included depiction of the use of contraceptives. Concurrently, the age of initiation of heterosexual intercourse has decreased and the number of teenaged pregnancies has remained high. Are these trends related? This survey of 391 adolescents found that those who chose heavier diets of sexy television shows were more likely than those who viewed a smaller proportion of sexual content on television to have had sexual intercourse. This relationship held regardless of perceived peer encouragement to engage in sex and across race and gender groups. While causal direction is not clear from these data, the relationship suggests that either sexual activity results in increased interest in sexual content in the media and/or that viewing such content leads to sexual activity. In either case, the finding points to the need for further research and increased discussion and portrayal of the use of contraceptives on television. 相似文献

This paper presents a simplified model that has been found to be useful for those learning questioning skills within the Milan systemic approach to family therapy as well as for those who simply wish to develop some skills in circular interviewing. The model begins with the premise that clients frequently describe a problem in terms that are either too broad or too narrow. The model has two categories of questions: those that draw connections and thus broaden a client's understanding of their context and those that draw distinctions and thus narrow a client's focus where generalisations predominate. The model is presented within the context of other models of Milan systemic questioning and the contributions they have made. 相似文献

The paper is based upon ethnographic research undertaken in a large metropolitan Careers Service in England. A consideration of differences between the intent and the outcome of action leads to an exploration of the ways in which white people come to understandings of their superordinate position relative to black people. By emphasising the concept of the materiality of ideology, the analysis attempts to go beyond a functionalist model which would regard a state apparatus as meeting the‘requirements’of capital in an unmediated and direct way. It is argued that racist ideology, as a specific set of linked but contradictory ideas, must inhere unevenly within the structures of everyday life and that struggles against racism have to take into account the discriminatory nature and importance of white‘non-racism’ 相似文献

Subjects filled out three touch attitude scales, a measure of recollections of early childhood touch, and a social competence inventory, and then proceeded to record their touches in a log for one week. The touch questionnaires, although correlated with one another, did not predict day-to-day touching as recorded in logs. However, the results also suggest that questionnaire responses (for the one recall measure and two attitude scales) and log records are each independently predictive of social self-confidence. These findings are interpreted to mean that both positive attitudes/remembrances about touch and active engagement in touch behavior are important elements in social competence. Implications for future research are discussed, including the suggestion that the possible effects of skills training in touch on tactile attitudes, touch communication practices, and social self-esteem should be investigated.Stanley E.

The onset of the 21st century sees the U.S.-Mexico border facing numerous challenges in meeting demand for water resources across a diverse set of interests, while also protecting water quality and providing for in-stream uses. This chapter surveys ongoing water resource management efforts in the border region and also examines a broad transboundary water resource management literature to identify existing innovations of note and also to offer ideas for future research. The increasing role of public participation and a democratic decision and policy making process, watershed-based approaches to transboundary water resource management, and the role of water markets are useful areas of investigation uncovered. I suggest that these concepts can form the foundation for future research efforts that may be fruitful in examining the many water resource management challenges that the region will face in the future. 相似文献

Summary. When a number of distinct models contend for use in prediction, the choice of a single model can offer rather unstable predictions. In regression, stochastic search variable selection with Bayesian model averaging offers a cure for this robustness issue but at the expense of requiring very many predictors. Here we look at Bayes model averaging incorporating variable selection for prediction. This offers similar mean-square errors of prediction but with a vastly reduced predictor space. This can greatly aid the interpretation of the model. It also reduces the cost if measured variables have costs. The development here uses decision theory in the context of the multivariate general linear model. In passing, this reduced predictor space Bayes model averaging is contrasted with single-model approximations. A fast algorithm for updating regressions in the Markov chain Monte Carlo searches for posterior inference is developed, allowing many more variables than observations to be contemplated. We discuss the merits of absolute rather than proportionate shrinkage in regression, especially when there are more variables than observations. The methodology is illustrated on a set of spectroscopic data used for measuring the amounts of different sugars in an aqueous solution. 相似文献

Foster parent perceptions of placement breakdown 总被引:1,自引:0,他引:1
The purpose of the study was to describe the perceived causes of placement breakdown by foster parents. Sixty-three foster parents from fifty families were asked to describe their challenges in response to the following question: “What would make you consider ending a foster placement”? The responses to this question were analyzed using multidimensional scaling and cluster analysis, to yield nine themes. Foster parents indicated that they would consider ending a placement if there was a danger to their family, if the child could not adapt to the home or if they could not handle the child's behavior. Participants reported that the complex health needs of a foster child, problems dealing with the foster agency, and several unsuccessful attempts to make the placement work would cause a placement to breakdown. Foster parents also indicated that they would consider ending a placement if their personal circumstances changed, their own health deteriorated, or there was a lack of appropriate external support in place. The results of the study point to gaps in the research on violence in general foster care, foster parent perceptions of contributions to a foster child's transition back to his or her birth family, and the process of foster parent decision-making in cases of placement breakdown. 相似文献
