It is uncertain whether Latin America and Caribbean (LAC) countries are approaching a single mortality regime. Over the last three decades, LAC has experienced major public health interventions and the highest number of homicides in the world. However, these interventions and homicide rates are not evenly shared across countries. This study documents trends in life expectancy and lifespan variability for 20 LAC countries, 2000–14. By extending a previous method, we decompose differences in lifespan variability between LAC and a developed world benchmark into cause-specific effects. For both sexes, dispersion of amenable diseases through the age span makes the largest contribution to the gap between LAC and the benchmark. Additionally, for males, the concentration of homicides, accidents, and suicides in mid-life further impedes mortality convergence. Great disparity exists in the region: while some countries are rapidly approaching the developed regime, others remain far behind and suffer a clear disadvantage in population health.  相似文献

为情而造文与为文而造情在《文心雕龙·情采》篇中以一组对立的概念出现,关于为情而造文历来受到研究者们的肯定与重视,但为文而造情一直遭到尖锐的批判,只有个别学者加以研究与肯定。关于两者的比较研究目前尚未开展,对二者进行比较研究,有助于探索文学本位,正确对待儒家传统文化。  相似文献

在刑事非法证据排除规则的具体运用中,"非法证据"的界定是当然前提。非法证据并非是任一证据合法性要件欠缺的广义非法证据,而专指取证主体通过严重非法的手段或者侵犯公民基本权利的方式所获取的证据材料。我国刑事非法证据包括非法言词证据和非法实物证据两类,两类非法证据在实际判断中虽存在差异,但都应围绕取证手段的非法性展开,分别考察取证手段是否违反法律规定以及违法的严重程度,以准确界定刑事非法证据的范围。  相似文献

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.  相似文献

One of the main subjects, governments have been facing is fair distribution of income, and making effort to improve it. In this study, we evaluated the effects of economic (energy, water, ICT) and social (health, education) infrastructure expenses on income inequality in the Iranian provinces for the period of 2007–2016 by the panel corrected standard errors (PCSE) model. The results show that social and economic infrastructures improvements reduce income inequality. However, the magnitude of these effects varies. Investment on education, healthcare, communication technology, energy, and water infrastructures has the greatest impact on income inequality reduction, respectively. Therefore, in order to reduce inequality in deprived areas, combination and optimal allocation of economic and social infrastructures should be considered.  相似文献

Understanding the reliability of hazardous organizations and their protective systems is central to understanding the risk they produce. Work on “high reliability organization” has done much to illuminate the conditions in which social organization becomes reliable in highly demanding conditions. But risk depends just as much on how relying entities do their relying as it does on the reliability of the entities they rely on. Patterns of relying are often opaque in sociotechnical systems, and processes of relying and being relied on are mutually influencing in complex ways, so the relationship between relying and risk may not be at all obvious. This study was an attempt to study relying as a social practice, in particular analyzing how it had ecological validity in a social organization—how practice was responsive to the conditions in which it took place. This involved observational fieldwork and inductive, qualitative analysis on an offshore oil and gas production platform that was nearing the end of its design life and undergoing refurbishment. The analysis produced four main categories of ecological validity: responsiveness to formal organization, responsiveness to situational contingency, responsiveness to information asymmetry, and responsiveness to sociomateriality. This ecological validity of relying practice should be a primary focus of risk identification, assessing how relying can become mismatched to reliability in certain ways, both when relying practice is responsive to circumstances and when it is not.  相似文献

目前我国农户的地权诉求已经发生了很大的变化,即由地权稳定、自主经营向农地资源的优化配置和高效利用转化。这一变化的内在动力是农户急切希望改变承包地过于细碎化以及改善农业生产经营基本条件。考察我国农地制度的发展史可以发现,我国农地制度变迁的基本逻辑就是农户的地权诉求决定农地制度的发展方向,这一点在当下一些地方的农地制度创新试验和经验中再次得到证明。今后我国农地制度创新必须遵循这一逻辑,根据我国农户地权诉求的变化,实施农户自愿前提下的承包地连片重划,争取国家对承包地重划制度的支持,强化农民集体民主决策制度,地方政府也要给予必要的支持。  相似文献

一般而言,历史课及其任课教师是比较受初中起点幼师大学生欢迎的。与此同时,历史课教学中也时常不经意间在教学内容安排、教学方法运用和教学观点表达等方面出现过度教学现象。学生主体地位的异化,教学过程把控失当和教学反思的缺位,是造成过度教学的主要原因。消除过度教学现象的对策主要是坚持教学过程中学生的主体地位,掌握教学有度的艺术和重视教学反思。  相似文献

农地产权结构是搭建土地增值收益分配与宪法秩序有效链接的重要桥梁.从农地产权结构变迁的视角看,我国传统土地增值收益的国有化机制实际在很大程度上符合1982年宪法所确立的社会主义地租国有原则及地利共享秩序.然而,由于宪法土地条款一开始就被注入了地利分配具有倾向性的思想基因,长此以往便忽视了农民作为整体分享土地增值收益的"另一半宪法秩序".新型城镇化背景下,国家进行了"同地同权"、赋权于"民"的农村土地管理制度改革,其实质是宪法秩序的延续而非替代,我国土地增值收益分配的主要机制仍是征地补偿制度.要实现我国土地增值收益的公平分享,必须回到社会主义"国家—集体"一元论的完整地利共享秩序中来,并遵循实质平等的要求,通过以"人的城镇化"为目标对区片综合地价进行限定、采取倾向于农村及农业发展的"土地财政"政策、打破城乡户籍二元制实现城乡一体化发展等方案,推动农民全过程参与、共享土地利益.  相似文献
