China’s middle-aged and older women suffer from poorer health than men. Using national baseline data from the China Health and Retirement Longitudinal Study (CHARLS), a survey conducted from 2011 to 2012, this article applies logistic models to investigate the association between female fertility history (parity, early childbearing, late childbearing) and middle-aged and late-life health. We find that parity is related to the mid-late-life health of women. Women with four children or more are more likely to suffer from activities of daily living (ADL) impairment and poorer self-rated health than those with one to three children. Early childbearing is associated with ADL impairment; however, the correlation is mediated by socioeconomic status. Early childbearing is related to self-rated health in later life by an indirect-only mediation effect via educational attainment and personal income.  相似文献

以审委会为代表的案件讨论机制的实践合理性正日益受到社会情境因素的影响,由此产生审委会决策机制的功能限缩问题。在审委会实际角色作用逐渐转变的过程中,法官会议讨论程序逐渐浮现并得到制度化。法官会议所具有的“正反校验”作用有助于解决疑难案件中法律适用的权威来源问题,很大程度上替代审委会规范法律适用的功能。法院内部案件集体讨论机制的流变,反映的是法院内部权力集中度的差异,即从审委会的功能限缩到法官会议的制度化呈现出从集体决策权到集体讨论权的权力变迁过程。与之相对应的是,法官群体在审判权力方面渐进的规模化、结构化、自主化,集体理性走向个体理性的过程得到强化。  相似文献

《1844年经济学哲学手稿》和《神圣家族》都是马克思主义创始人早期思想的代表性著作,二者都把“生活”作为重要概念进行论述。从作为经济学哲学概念到作为社会批判概念,马克思主义创始人对“生活”的认识经历了从对物质生产活动的重视到对无产阶级普遍贫困生活的揭露,从分析“生产生活”的异化到对“非人性”生活的批判,从“生活的手段”到消灭“非人性的生活条件”的思想历程。人类的历史是人类生活发展的历史。解决人的美好生活如何实现的问题,在马克思恩格斯的生活思想中居于核心地位,这对当今中国具有重要的理论指导价值。中国特色社会主义进入新时代,从开启一种全新文明的生活形态的高度来理解新时代的美好生活,才能准确把握我国社会主要矛盾变化的深刻意义。  相似文献

Background

The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.

Objectives

The aim of this project is to determine, assess and identify the real impact of breastfeeding support networks in Murcia (Spain).

Methods

After searching unsuccessfully for a validated questionnaire, a specific one was developed and validated for measuring the impact of formal and informal support networks through five dimensions: satisfaction, consultation, experience, problems and support. The questionnaire was provided to 500 mothers with experience in breastfeeding, who brought their children to baby paediatricians between 2 June and 27 November 2014. Upon completion of the survey and fieldwork, a detailed statistical analysis was conducted.

Results

The degree of satisfaction perceived by the users of the services of support breastfeeding networks is remarkable. In addition, mothers who clarified their doubts and discussed their problems with health professionals and/or breastfeeding support networks were more likely to breastfeed for a longer duration compared to those who did not (p = 0.005). Furthermore, mothers who sought support in breastfeeding are more likely to breastfeed for more than 6 months (p < 0.0005).

Conclusion

Based on this information, we conclude that breastfeeding support networks have a positive influence in the duration of a women’s decision to breastfeed.  相似文献

国家角色模式的演变主要着眼于国家任务的承担及其实现方式的变化,近代以来,国家角色模式经历了从夜警国家到福利国家再到担保国家的三次嬗变。民营化及公私合作的发展促使国家与私主体越来越多地共同承担公共任务,分担了福利国家的给付之累,也促进福利国家模式向担保国家模式转变,其中,行政任务的民营化及公私合作是担保国家模式的主要背景,担保国家理论便是要探讨在民营化及公私合作背景下国家对公共任务的最终落实如何承担担保责任。担保国家与合作国家内涵相近但各有侧重,且均有重大意义。  相似文献

In the last two decades, the Portuguese Government has responded to the decline of centres of commerce. In this paper, we analyse the three different experiences of town centre management (TCM) schemes developed in Portugal since the turn of the millennium. The first two stages were developed using public sector initiatives and their impacts were limited. The third stage is still under way and is composed of private projects created by local business owners. Taking Lisbon as a case study for this third stage we conclude that these projects have become a pro-active means of intervention in Portuguese town centres.  相似文献

This article focuses on the official and semi-official Iranian coverage and representation of the 1981 republican prisoners’ hunger strike in Northern Ireland and the related corporeal constructs of the hunger strikers as ‘martyred’ bodies. The particular characterization and utilization of Irish republican hunger strikers by media outlets, officials, and other propagandists of the Islamic Republic of Iran (IRI) was an instance of groups outside Northern Ireland appropriating Irish nationalist bodies for their own ends. IRI commentators re-articulated the starving bodies of Irish republican hunger strikers, re-infusing them with symbolic meanings in a cross-cultural and ideologically laden configuration in the service of IRI’s self-projection as the patron of worldwide struggles for justice and liberation against the twin forces of imperialism and domestic opponents. In the process, IRI added its own layers of agency and politically crafted somatic meaning to the hunger strike. Meanwhile, IRI’s extensive advocacy of the republican hunger strike in Northern Ireland was eagerly welcomed by the Provisional Irish Republican Army (PIRA), to which most hunger strikers belonged; with PIRA and its political wing, Provisional Sinn Féin, hoping to secure diplomatic recognition, and possibly material aid, from the Iranian government for bolstering PIRA’s domestic and international standing vis-à-vis the British government.  相似文献

盖恩斯在《刑前一课》里从零视点与悬念的建构、外视点与悖论的建构、内视点与意识流、多视点聚焦与立体感等方面来研究小说视点与叙事层面的相互关联。他从零视点的角度建构人称悬念、瞬间悬念和期待性悬念,从外视点的角度设置了主题悖论、言辞悖论和语境悖论。为了克服零视点和外视点描述的单调性和乏味性,盖恩斯把内视点与意识流进行了有机结合,从触景生情式意识流、内心独白式意识流和交织式意识流等方面探究人物心理与社会环境的内在关联。他还在人物评述和场景氛围等方面采用了多视点策略,从多层次和多侧面的角度来聚焦于具体的人物、物件或场景,构建了叙事层面的立体感,拓展了现代黑人小说创作的美学认知空间。  相似文献
