As parental ages at birth continue to rise, concerns about the effects of fertility postponement on offspring are increasing. Due to reproductive ageing, advanced parental ages have been associated with negative health outcomes for offspring, including decreased longevity. The literature, however, has neglected to examine the potential benefits of being born at a later date. Secular declines in mortality mean that later birth cohorts are living longer. We analyse mortality over ages 30–74 among 1.9 million Swedish men and women born 1938–60, and use a sibling comparison design that accounts for all time-invariant factors shared by the siblings. When incorporating cohort improvements in mortality, we find that those born to older mothers do not suffer any significant mortality disadvantage, and that those born to older fathers have lower mortality. These findings are likely to be explained by secular declines in mortality counterbalancing the negative effects of reproductive ageing. 相似文献

目前,以手机终端为依托的微信传播技术不仅给社会传播方式带来了前所未有的改变,而且给社会风险信息的传播获取以及公众对风险的感知与判断,甚至政府的风险决策与治理方式都带来了巨大的挑战.鉴于此,选取了比较典型的案例——山东“问题”疫苗事件作为探讨对象,结合相应的统计资料,深入分析了在此案例中微信传播呈现出的显著特征,即传播内容庞杂未见明显的“沉默螺旋”的显现,传播态度多元化但偏于激动,传播迅速集中但议题缺乏持续的关注.研究认为,正由于这样的传播特征加之疫苗风险本身的特征与个体的偏颇性解读,使公众对“问题”疫苗事件产生了强烈的风险感知,并在一定程度上造成了疫苗的污名化结果.因此建议微信时代一定要警惕媒介化的风险,风险沟通要在同理心的基础上进行,要引导公众对风险议题进行持续理性的关注等. 相似文献

AbstractUsing life story interviews with 10 Sri Lankan Tamil refugees resettled in Australia, this article shows how family separation in experiences of civil war and resettlement produce long-lasting and emotional memories of fear and determination. The findings explore how young Tamil people gave meaning to family when they interacted with key individuals and negotiated cultural practices in different spaces. Moreover, intergenerational family narratives emerged as a key practice through which Tamils preserved the family identity. The analysis demonstrates how and when family separation can manifest in personal memories to reveal stories of agency and resilience. A critical engagement of the past can help to better understand concepts of childhood in relation to family and family separation in war affected diaspora communities. 相似文献

Schools at the P-12 level increasingly face crises related to school shootings, violence, and other tragedies. Understanding the communication challenges schools face is paramount to assisting schools with communication before, during, and after crisis events. The current study focuses on the challenges created by media interest in such crises and the strategies implemented to overcome these challenges and provide responsible information to stakeholders. Interviews conducted with 21 school crisis teams at the P-12 level revealed that sensationalism, seeking alternative routes to information, and framing were key challenges in working with the media. In light of these challenges, administrators focused on creating media plans, building relationships with the media, being accurate but guarded, and communicating reassurance and reunification. Implications are discussed for school districts nationally. 相似文献

Adult Protective Services (APS) workers are exposed to substantial occupational hazards and job stress, but these stressors are underdocumented. Therefore, we sought to describe APS workers’ work environments and responses to occupational hazards and stressors, including compassion fatigue, burnout, and secondary traumatic stress. Survey data were gathered with closed-ended questionnaires administered to APS workers in an urban setting. Virtually all workers (97%) reported exposure to one or more environmental hazards in their work, and 80% reported hazard exposure in the past month. Workers also reported mixed responses to their work environment and to experiences with supervision. A sizable minority (22.7%) was at high risk for burnout, 24.6% were at risk for secondary traumatic stress, and 19.9% reported low compassion satisfaction. The results document multiple stressors in APS work. The APS partner is committed to ongoing efforts to better support its staff, and these findings can inform future efforts to enhance supervisor support and worker self-care, to minimize burnout and secondary traumatic stress. 相似文献

Despite the prevalent assumption among scholars of social movements and contentious politics that transformative contentious events are also the focus of public attention and discussion, there has been little attempt to substantiate this. After making a case for why to focus on focusing events and suggesting that these events should be thought of as products of a dialogical contentious meaning‐making process, we develop a coverage attribute‐based method for identifying focusing events. For illustrative purposes, we apply our method to the coverage of contentious events during the “first” intifada by Israeli‐Jewish, Jewish settler, and Palestinian newspapers. Findings from analyses of 11,868 news items reveal that newspapers are likely to strategically quiet contentious events that are strategically amplified by newspapers affiliated with opposing or targeted parties, and vice versa, depending on their interpretation of these events as political opportunities or threats. Analyses of variations across and within contending parties reveal the role of structure and agency in the dialogical seesaw‐like dynamics of contentious meaning‐making. 相似文献

孟子云“夭寿不贰,修身以俟之,所以立命也”,其中包含着“夭寿(生死)与命之间的关系”以及“修身立命”这两方面的问题。海德格尔《存在与时间》在时间的视域下,将此在解读为“向死而在”,与言说“生生之大德”的儒者形成一种互补关系。命定的偶然性(个体的人必然有具体的实质限定)、必死性(有限个体必有其死)和使命义(人禀受善性而有道德使命)这三者构成了《孟子》中的“命”义。孟子反求诸己,追求人的本然善性和生之尊严;海德格尔则认为面对死亡的决断,是个体成为本真存在的关键,而儒者的生活方式可视作本真存在的一种可能性。 相似文献

There has been increasing use of quality-of-life (QoL) instruments in drug development. Missing item values often occur in QoL data. A common approach to solve this problem is to impute the missing values before scoring. Several imputation procedures, such as imputing with the most correlated item and imputing with a row/column model or an item response model, have been proposed. We examine these procedures using data from two clinical trials, in which the original asthma quality-of-life questionnaire (AQLQ) and the miniAQLQ were used. We propose two modifications to existing procedures: truncating the imputed values to eliminate outliers and using the proportional odds model as the item response model for imputation. We also propose a novel imputation method based on a semi-parametric beta regression so that the imputed value is always in the correct range and illustrate how this approach can easily be implemented in commonly used statistical software. To compare these approaches, we deleted 5% of item values in the data according to three different missingness mechanisms, imputed them using these approaches and compared the imputed values with the true values. Our comparison showed that the row/column-model-based imputation with truncation generally performed better, whereas our new approach had better performance under a number scenarios. 相似文献

现代性危机已经渗入到日常生活之中,日常生活被消费所控制和引导,人们为商品而迷狂,为体验消费而忘记质疑和批判.消费被全面地控制掩盖了社会矛盾,阻碍了人们正确认识社会;造就了一个恐怖主义社会,人们患上恐怖症;消费衍生出众多"次体系",它们难以构成对社会的一致反抗.列斐伏尔提倡对日常生活进行一种永恒的文化革命,这种革命要继承哲学传统,要担负起确认和阐释新的日常生活的责任,其目标是要建立一种都市主义. 相似文献
