Stressors beget stressors: The effect of passive leadership on employee health through workload and work–family conflict

The current study examined passive leadership as a potential antecedent of two commonly studied workplace stressors (i.e. workload and work–family conflict), and investigated its negative effect on employee burnout and physical symptoms via these stressors. We collected two waves of data from 274 focal participants, and one wave of data from their co-workers. Results showed that both self-reported and co-worker-reported passive leadership was positively related to employee burnout and physical symptoms, as well as workload and work–family conflict. Additionally, workload and work–family conflict partially mediated the effects of passive leadership on burnout and physical symptoms, respectively. Our findings support the notion that passive leadership can create a stressful workplace and have a detrimental effect on employees’ health.     

一种简单有效的二项分布比例参数似然比置信区间的求法

对二项分布比例参数p的似然比置信区间,提出一种简便求解方法。在平均覆盖率、平均区间长度及区间长度的95%置信区间准则下与WScore、Plus4、Jeffreys置信区间进行模拟比较。试验表明,在二项分布b(n,p)的参数n≥20且p∈(0.1,0.9)时,该方法获取的似然比置信区间性能优良。当点估计p值不是接近于0或1且n≥20时,推荐使用本方法获取p的置信区间。

瑜伽运动对女大学生身心健康的影响

运用文献资料法、调查法、实验法和数理统计法对定期参加瑜伽运动的高校女大学生进行调查研究,提取其实验前后身体形态、身体机能、身体素质、心理健康四个方面的多项数据,探讨了瑜伽运动对高校女大学生身心健康的影响。研究结果表明：瑜伽运动可以改善高校女大学生身体形态、提高肺活量、降低安静时心率、改善身体机能,并能提高身体柔韧性和平衡能力,使其整体心理健康水平呈显著性提高。瑜伽运动是提高女大学生身体健康水平的有效手段之一,是新兴的有待进一步开发的重要课程资源。     

河北省体育教育专业毕业生就业状况调查分析

采用文献资料、访谈及问卷调查等方法,对河北省体育教育专业毕业生就业状况从就业准备、就业意识、就业意向、就业主动性、就业消费、就业挫折以及就业教育上进行了调研。结果表明：相当数量毕业生就业准备不够充分;就业意识还有待加强;就业意向存在理想化倾向;就业的主动性还需进一步加强;就业消费较低．且消费项目分散,同时毕业生应理性面对就业消费不断增加的现实;就业烦恼主要来自用人单位要求学历较高、社会需求较少、恋人同城理想难以实现和都市情节;就业教育相对滞后,就业指导工作还需要进一步加强。

Home Modifications among Community-Dwelling Older Adults: A Closer Look at Race and Ethnicity

ABSTRACT

This study investigated racial and ethnic differences in home modification use. Data from the 2011 National Health and Aging Trends Study were used (n=6,764). Compared with non-Hispanic Whites, Hispanics were less likely to have a grab bar (odds ratio (OR) = 0.6), bath seat (OR = 0.8), or raised toilet (OR = 0.6). Non-Hispanic Blacks were less likely to have a grab bar (OR = 0.7) or bath seat (OR = 0.7) than non-Hispanic Whites, but more likely to have a raised toilet (OR = 1.3). English proficiency largely explained ethnic differences, while health status partially accounted for racial disparities.     

Identification-robust moment-based tests for Markov switching in autoregressive models

ABSTRACT

This paper develops tests of the null hypothesis of linearity in the context of autoregressive models with Markov-switching means and variances. These tests are robust to the identification failures that plague conventional likelihood-based inference methods. The approach exploits the moments of normal mixtures implied by the regime-switching process and uses Monte Carlo test techniques to deal with the presence of an autoregressive component in the model specification. The proposed tests have very respectable power in comparison with the optimal tests for Markov-switching parameters of Carrasco et al. (2014 Carrasco, M., Hu, L., Ploberger, W. (2014). Optimal test for Markov switching parameters. Econometrica 82(2):765–784.[Crossref], [Web of Science ®] , [Google Scholar]), and they are also quite attractive owing to their computational simplicity. The new tests are illustrated with an empirical application to an autoregressive model of USA output growth.
