Reciprocal relationships between psychosocial work characteristics and sleep problems: A two-wave study

Sleep problems are common and impair the health and productivity of employees. Work characteristics constitute one possible cause of sleep problems, and sleeping poorly might influence wellbeing and performance at work. This study examines the reciprocal associations between sleep problems and psychosocial work characteristics. The participants were 1744 full-time employed individuals (56% women; mean age 38 years in 2007) from the Young Finns study who responded to questionnaires on work characteristics (conceptualised by the demand–control model and effort–reward imbalance model) and sleep problems (Jenkins Sleep Scale) in 2007 and 2012. Cross-lagged structural equation models are used to examine the associations. The results show that low control and low rewards at baseline predicted sleep problems. Baseline sleep problems predicted higher effort, higher effort–reward imbalance, and lower reward. Sleep problems also predicted lower odds for belonging to the low (rather than high) job strain group and active jobs group. The association between work characteristics and sleep problems appears to be reciprocal, with a stressful work environment increasing sleep problems, and sleep problems influencing future work characteristics. The results emphasise the importance of interventions aimed at both enhancing sleep quality and reducing psychosocial risks at work.     

“国防一线”的“三线建设”——云南三线建设的历史研究

云南处于援越抗美和对越自卫反击战的国防一线,同时又是我国地缘国防战略的大后方。既是“一线”又是“三线”的特殊地缘政治环境,赋予了云南三线建设独特的面貌和经验。在1964年至1980年的云南三线建设历程中,经历了两个建设高潮。文章试图真实再现各个阶段的规划部署、实施过程,分析出现的问题,以弥补相关研究的不足。这场特殊的“备战经济”建设,为保卫边疆安全、巩固国防发挥了应有的作用,同时也为云南的经济社会发展做出了重大的贡献。     

Agreement and discrepancy between children,parents, and social workers on school‐based effort avoidance in child welfare services

A multiperspective approach is beneficial for obtaining reliable and multifaceted pictures of child behaviour problems. The goal of the present study is to examine interrater agreement on school‐based effort avoidance between children receiving child welfare services, parents, and social workers. Given previous findings, interrater agreement is expected to be low. Self‐reported data on school‐based effort avoidance were gathered for children and adolescents in child welfare services. Additionally, social workers (using the Teacher‐Report Checklist for social and learning behaviour) and parents (using the parallel version of the self‐rating questionnaire on school‐based effort avoidance) were asked to complete an external assessment tool to compare children's perspectives with the ratings of significant adults. The results confirmed significant discrepancies between parents' and children's ratings on effort avoidance tendencies. Furthermore, there were only small to moderate correlations between children's self‐ratings and the adults' assessments; however, the consensus between adults was higher than the interrater agreement between children and social workers. Discrepancies in ratings from multiple informants underline the importance of integrating multiple perspectives, especially children's perspectives, in the diagnostic process in order to plan and adapt appropriate care and treatment.     

中国房地产税制:存在问题与改革设想

在现代市场经济条件下,房地产税制具有十分重要的功能。现阶段中国房地产税制存在房地产税收功能分散,房地产税种设置交叉重叠现象突出,计税依据不符合国际惯例,房地产保有环节税负偏轻和房地产税权分布结构不合理等问题。中国房地产税制改革已进入基础性制度建设阶段,必须按照"宽税基、简税种、低税率"的原则,实现房地产开发流转环节税收为主向房地产保有环节税收为主的房地产税制转型,去土地财政化,这就要适时开征房产税。开征房产税可以分两步走,近期对居民新购商品房超免税标准部分征收房产税,中长期覆盖到居民已购存量房地产。

气候资源的权力与权利：基于公共财产属性的构造

气候资源不是《宪法》、《物权法》上明确列举的国家所有权客体,也不具有权利客体的特征。气候资源与国家所有权客体在权利归属、表现形态、使用方式、存在目的上存在较大差异,乃是一种公共财产。基于公共信托理论,国家是公共财产的受托人,对气候资源行使诸如气候资源规划权、保护区设立权、纠纷裁决权及开发利用行政许可权等管理权。因为气候资源不是国家所有权客体,源自气候资源国家管理权的民事主体对气候资源开发利用的权利乃是特许物权。气候资源特许物权具有公私兼容的性质,既具有公法性,又具有私法性。
