Athletes are a population group with unique vulnerabilities whose social work-related needs are often not met. Because of the perception that they are young and healthy, athletes are seen as free from mental health challenges and social problems. Yet athletes are at high risk for distress due to pressures to perform, avoid showing pain, hide physical injuries and substance abuse problems, eating disorders and burnout. At the same time, they may have false support systems that are interested in the athlete for social or monetary status. Social workers are broad systems practitioners who can focus on how the environment and other influences affect an athlete's mental health and well-being. Because social workers are strengths-based, they can assist athletes in achieving their highest level of functioning on and off the playing field.  相似文献

This study examines the relationship between accounting and market-value measures of profitability for individual firms. Differences in measures of profitability are observed both between and within industry groups and thus cannot be explained by differences in uncontrolled industry-specific influences. We suggest that both accounting and market can be used as unique but imperfect indicators of profitability. Using a LISREL model approach, we find R & D intensity, television advertising intensity, leverage, and industry growth to be important determinants of firm profits.  相似文献

高校师资管理模式探讨——以工科院校为例   总被引:1,自引:0,他引:1  
工科院校为社会发展和科技进步提供了大量的创新人才和建设人才,而人才培养的关键取决于教师的教学水平、知识结构和积极主动性。面对新的挑战,工科院校应该通过转换理念、优化环境、加强能力培养、改革评价体系、促进团队建设等方式来有效地进行师资培养,提升工科院校的整体师资水平.  相似文献

The use of wildlife resources is governed by a combination of private contracts and public regulations. Most often, private landowners control access rights, and government agencies regulate hunting and other uses. This paper shows that these institutions depend on wildlife values and the ability of private landowners to control access to species that inhabit their land. Logit regressions and literary sources are used to test implications about private hunting rights and state regulations. The data support the view that private, legal, and political forces have led to institutions that vary in ways consistent with wealth maximization.  相似文献

In environmetrics, interest often centres around the development of models and methods for making inference on observed point patterns assumed to be generated by latent spatial or spatio‐temporal processes, which may have a hierarchical structure. In this research, motivated by the analysis of spatio‐temporal storm cell data, we generalize the Neyman–Scott parent–child process to account for hierarchical clustering. This is accomplished by allowing the parents to follow a log‐Gaussian Cox process thereby incorporating correlation and facilitating inference at all levels of the hierarchy. This approach is applied to monthly storm cell data from the Bismarck, North Dakota radar station from April through August 2003 and we compare these results to simpler cluster processes to demonstrate the advantages of accounting for both levels of correlation present in these hierarchically clustered point patterns.

This article uses matched pairs of sons and their parents from the National Longitudinal Surveys: Old Cohort Databases to investigate the relationship between the marital history of parents, educational attainment, and intergenerational correlations in earnings. The research indicates that patterns of intergenerational earnings mobility vary with divorce. Sons from families whose divorced parents had relatively low earnings have a greater chance of having low earnings themselves. The research also shows that much of the variation in earnings mobility can be explained by lower educational attainment for children from divorced families. This finding highlights the importance of designing policies to assist the educational attainment of those most likely to be affected by divorce.  相似文献

The “passive” welfare state was accused of promoting a dependency culture. “Active” welfare and the “what works?” approach of Britain's New Labour government is allegedly implicated in an age of post‐emotionalism, in which people are largely indifferent to the needs of others and committed primarily to their personal well‐being. This article, first, seeks to extend recent debates about agency and motivation in social policy and relate them to the notion of post‐emotionalism. Second, it draws on a recent empirical study of popular and welfare provider discourses, which suggests that popular opinion can accommodate an appreciation of human interdependency, while welfare providers remain committed to a public service ethos. None the less, Third Way thinking is associated with a narrowing of solidaristic responsibilities. The problem for the future of health, social care and state welfare policies lies not with the imagined consequences of post‐emotionalism, so much as with an ideological context that perpetuates a distorted ethic of responsibility.  相似文献

This paper explicitly characterizes the general nonnegative-definite covariance structure for a multivariate normal random vector such that the univariate sample variance is distributed exactly as if the sample observations are normal independent and identically distributed (i.i.d.). This work extends the results of Baldessari (1965) and Stadje (1984) who have characterized the general positive-definite covariance matrix such that the univariate sample variance is distributed exactly as if the sample observations are normal i.i.d.  相似文献
