Mindfulness and health behaviors in college students: The moderating role of sleep

Abstract

Objective: To examine the moderating effects of subjective sleep quality (SSQ) and sleep duration on the relationships between mindfulness and health behaviors (i.e. nutrition and exercise) among undergraduate students. The unique influence of the five facets (i.e. factors) of mindfulness (i.e. observing, describing, acting with awareness, nonreactivity to inner experience and nonjudging of inner experience) on students’ health behaviors was also explored. Participants: Three hundred fifty seven undergraduate students enrolled in U.S. colleges. Methods: Students completed an online survey. Hierarchical multiple regression analyses were conducted to determine whether SSQ moderated the relationship between mindfulness and nutrition behavior. Results: SSQ moderated the relationship between mindfulness and nutrition behavior. The observe facet of mindfulness was the most predictive of nutrition behavior, whereas the observe and describe facets were the most predictive of exercise behavior. Conclusions: Interventions that target mindfulness and sleep quality may help promote healthy eating and increased exercise engagement in college students.     

失业保险给付期限差异下的失业持续时间研究

本文对享受不同失业保险给付期限的失业者的失业持续时间差异进行了实证研究。根据工作搜寻理论,应用存活分析方法建立了含有失业保险给付期限因素的失业持续时间模型,并对青岛市失业者登记数据进行了实证研究。结果表明:享受失业保险者的失业持续时间明显长于不享受失业保险者的失业持续时间,在失业保险给付额度相同的条件下,失业保险给付期限与失业持续时间成同向变动关系。     

Analysis of incomplete durations with application to contraceptive use

Models for analysing incomplete durations obtained from cross-sectional surveys are presented. The aim of the paper is to develop a framework for analysing the incomplete duration of episodes in progress at the time of the survey by formulating generalized linear models and fitting and assessing them by using standard statistical packages. The maximum quasi-likelihood method is used for model fitting. The choice of the distribution and the diagnostic procedures are discussed. Simulated data from two distributions (the Weibull and log-logistic distributions) are used to evaluate the methodology developed and to assess model misspecifications. A data set on the current use of the contraceptive pill from a cross-sectional survey in Egypt is analysed.     

中医古代文献使用时效长的原因初探

中医学具有很强的人文属性,它的思维、学科发展、理论形成和临床疗效的总结,都有其独特的方式方法。因此评判中医古代文献是否老化过时,不应仅以现代科技文献老化规律为标准,而应结合其自身的发展规律进行评判。

专利权出质登记制度研究——兼及《专利权质押合同登记管理暂行办法》的修改

专利权出质登记是专利权质权的生效要件.专利权出质登记应由国家知识产权局统一办理,且可因当事人一方申请而启动.登记机构对专利权出质登记实行形式审查,并辅之以实质审查,尽量保持登记系统所载内容的真实性.就登记事项而言,出质登记中不应记载专利证书的保管方式、专利年费相关事项以及质押期限.     

The multistate life table with duration‐dependence

A method for generalizing the multistate, or increment‐decrement, life table to include rates which depend upon duration of exposure to risk, as well as upon age, is proposed. The method is built upon the linear approximation, called the linear integration hypothesis, developed mainly by Rogers and his colleagues. Although the use of rates indexed by duration categories leads to a substantial increase in the state space of the model, it is possible to arrange the rates in such a way that matrices to be inverted are no larger than those encountered in the usual multistate life table. In the more general approach it is possible to derive several new summary indices of the life‐table cohort's history, such as the mean and median time in current status, at any age. The method is illustrated using a simple four‐state marital‐status model which has appeared often in the literature; here, rates of divorce and widowhood vary by duration of marriage as well as age.     

论人大代表候选人资格

人大代表候选人资格是指在人大代表换届选举中,一位公民被确定成为一名正式代表候选人所需要具备的基本条件,其内在价值为保障公民参与行使国家权力的权利空间,促进国家权力机关职能的有效发挥。对我国人大代表候选人资格的完善,有赖于对候选人的居住期限、教育程度和个人信用等要素进行研究,以期实现人大代表基本素质与履职能力的提升。这有利于我国各级人民代表大会职能的切实履行和人民代表大会制度优越性的充分发挥,有利于我国依法治国和国家治理现代化的全面深入推进。     

Labour Market Participation of French Women over the Life Cycle, 1935–1990

Employment histories with multiple spells and time varyingcovariates help identify determinants of labour markettransitions of women in France between 1935 and 1990. Higher educatedwomen were more likely to become inactive, but returned to work also moreeasily, especially when they added work experience. Being married,whether mother or not, induced a rearrangement of time betweenstaying at home and labour, in rendering exit from employment morelikely and return from inactivity to employment less likely. Exits from employment were lessfrequent for mothers of larger families, while return toemployment decreased with the total number of children, in spite of thegrowing financial needs of larger families. Transitions betweenemployment and inactivity increased with favourable economicconditions. However, involuntary exits from employment were moreprobable during economic downturns.     

Partially linear censored quantile regression

Censored regression quantile (CRQ) methods provide a powerful and flexible approach to the analysis of censored survival data when standard linear models are felt to be appropriate. In many cases however, greater flexibility is desired to go beyond the usual multiple regression paradigm. One area of common interest is that of partially linear models: one (or more) of the explanatory covariates are assumed to act on the response through a non-linear function. Here the CRQ approach of Portnoy (J Am Stat Assoc 98:1001–1012, 2003) is extended to this partially linear setting. Basic consistency results are presented. A simulation experiment and unemployment example justify the value of the partially linear approach over methods based on the Cox proportional hazards model and on methods not permitting nonlinearity.
