Association between sexually explicit messages and sleep health among French sexual minority men

It has been demonstrated that sexual minority men (SMM) participate in sexting. While research has shown that engagement in the exchange of sexually explicit media is associated with poor health outcomes, no previous research has investigated its association with sleep health outcomes. This study sought to examine the association between sexually explicit media and sleep health among SMM, a population that suffers from poor sleep health. A popular geosocial networking application was used to recruit SMM individuals (N?=?580) in the Paris, France, metropolitan area. Multivariate analyses, adjusting for sociodemographics, were used to test the association between the frequency of sexually explicit messaging and three dimensions of sleep health: (1) sleep quality, (2) sleep duration, and (3) two aspects of sleep problems. In multivariate analyses, those who reported engaging in sexually explicit messaging more were more likely to report getting less than seven?hours of sleep (aRR = 1.24; 95% CI = 1.08, 1.43) compared with those who reported engaging in sexually explicit messaging less. No significant associations were found between sexting and sleep quality or reporting sleep problems. Sexually explicit messaging was associated with shorter sleep duration. Intervention targeted at individuals who sext could potentially improve sleep health outcomes.     

遗属养老保险制度的机制设计研究

女性老龄人口特别是丧偶者面临更高的老龄贫困风险,老龄化背景下如何向更具脆弱性的丧偶独居女性老龄人口提供老龄收入保障,帮助其实现反贫困的目标是各国公共政策制定者面临的一项长期重要的挑战。遗属养老金的受益作为派生养老金权益的重要内容有利于阻止贫困和平滑消费,是帮助丧偶独居女性老龄人口反贫困的重要手段,世界各国普遍将其纳入强制性社会保障体系。但遗属养老保险制度可能带来对女性就业参与的不当激励,不公平的社会再分配效应及养老金财务支出负担增加等不利经济影响。对世界上30个主要国家和地区遗属养老保险制度机制设计的比较研究表明有必要通过良好的遗属养老保险制度机制设计来实现其阻止贫困的重要作用,尽可能降低其可能的负面经济影响。本文建议主要包括:合理确定遗属养老金的受益水平以切实满足遗属的生活支出需要;严格限定被保险人需满足的养老金缴费条件;严格限定受益遗属需满足的受益条件;加强遗属养老保险与老龄养老保险制度的立法衔接等。当前我国遗属养老保险制度是明显缺失的,未来我国在建立遗属养老保险制度的过程中有必要借鉴国际经验,优化机制设计,在充分发挥遗属养老保险制度对于丧偶女性老龄人口反贫困作用的同时将其潜在的负面经济影响降至最低。     

The nutrition-related information seeking behaviours and attitudes of pregnant women with a high BMI: A qualitative study

BackgroundThe prevalence of high body mass index is increasing amongst women of child bearing age. High maternal body mass index has ramifications for both mother and baby including increased health risks from gestational diabetes mellitus, caesarean section and stillbirth. Despite the increasing prevalence of high maternal body mass index little is known of the experiences of these women regarding nutrition information access and use during the antenatal period.MethodsA qualitative study using individual interviews was undertaken at a tertiary hospital in south-eastern Australia. Twenty-Eight women with a body mass index ≥30 kg/m² participated. Interviews were audio recorded, transcribed, cross-checked for consistency and entered into a word processing document for further scrutiny. Data was analysed using interpretative phenomenological analysis (IPA). In any phenomenological study the researcher’s objective is to elicit the participant’s views on their lived experiences.FindingsThree major themes emerged: (1) Nutrition-related information attainment; (2) Nutrition-related information management; (3) Nutrition-related information needs and wants.ConclusionThe findings from this study may assist the future development and dissemination of nutrition-related information for pregnant women with a high body mass index. Women want more individualised support regarding nutritional requirements during pregnancy.     

CEOs’ temporal focus,firm strategic change,and performance: Insights from a paradox perspective

Recent research indicates that CEOs’ temporal focus (the degree to which individuals attend to the past, present, and future) is a critical predictor for strategic outcomes. Building on paradox theory and the attention-based view, we examine the implications of CEOs’ past and future focus for strategic change. Results from polynomial regression analysis reveal that CEOs who cognitively embrace both the past and the future at the same time engage more in strategic change. In addition, our results reveal that the positive strategic change−firm performance relationship is enhanced when CEOs’ past focus is high, whereas CEOs’ future focus mitigates the translation of strategic change into firm performance (when their past focus is low at the same time). In addition, supplemental analyses indicate that the impact of CEOs’ temporal focus turns out differently in stable and dynamic environments. Our study thus extends the literature on both individual’s temporal focus and strategic change.

Linking family engagement with a rights perspective: macro factors influencing practice

While child welfare practitioners in many countries are struggling to develop methods of effective family engagement, they operate within different national and cultural contexts that influence, both positively and negatively, the ability to engage with families. Increasingly, international comparisons are necessary to further understanding of the development of social work practice. This is particularly necessary because most countries utilize international frameworks (such as the United National Convention on the Rights of the Child) to provide guidance in the development of policies, programs, and interventions. Each country (and locality) struggles to advance practice to be more effective and humane. Our paper offers a comparative analysis focused on family-oriented and rights-based frameworks of different countries. Based on a review of current national policies and a review of the literature regarding family-based practices, we examine similarities and differences among four countries: the United Kingdom, Sweden, the United States, and South Korea. These countries were selected because they have some similarities (advanced industrialized democracies, professional social work, and formal child protection systems) but have some differences in their social welfare systems (policies, specific practices, and socio-cultural context). These differences can be utilized to advance understanding regarding the promise and potential for family engagement strategies. We then discuss the utility of this comparison for theory-building in the arena of child-care practice and conclude by identifying the challenges and limitations of this work.

社会主义法治理念在检察工作中的深化与拓展——以检察文化建设为视角

社会主义法治理念是检察文化建设的根本指针,检察文化是社会主义法治理念的有效载体,两者互为依存,相互促进。社会主义法治理念在检察工作中深化与拓展的最终归宿是:符合社会主义法治理念核心要求的检察文化的形成。社会主义法治理念在检察工作中深化与拓展的基本路径是通过检察文化建设实现司法理念从宏观层面向微观层面的转化,即打击犯罪与保障人权相统一、程序正义与实体正义相统一、协作与监督相统一、法律效果与社会效果相统一、案件数量与案件质量相统一。
