简介:2018年已经过去,如果用一个汉字来描述自己的这一年,可能每个人都有不同答案。如果用一个汉字来形容一个国家的2018,哪个字会夺得'C位'呢?由中国国家语言资源监测与研究中心主办的'汉语盘点2018'评选,选出的中国年度代表字为'奋'。
简介:论文探讨从乡村汲取资源时代过渡为乡村振兴供给资源时代之后,强基层党建与公共资源供给关联问题。通过调查村庄内部原有资源禀赋:村庄经济资源、村庄社会资源、村庄公共资源和现有资源状况:经济精英担任村支书、村支书捐资修路、村支部再造村内关系,分析村支部援引村外资源拓展发展空间和集中村内资源谋划发展平台,得出强基层党建为精英整合型公共资源供给模式的结论。此模式通过国家与社会互动合作框架:重构乡村社会网络,完善乡村治理体系;再造乡村社会关系,引领乡村社会治理;重塑乡村社会组织机制,优化乡村治理结构;主导乡村社会互动机制,提升乡村治理能力,从而弥补村庄公共资源不足,解决村庄公共资源短缺问题。

简介:摘要目的分析4C延续性护理管理模式对产妇产后哺乳技能与喂养方式的作用。方法纳入研究对象来自我院产科2018年1月~2019年1月收治的96例产妇,将“随机数字表法”作为分组原则,分对照组(予以常规护理干预,48例)、研究组(予以4C延续性护理管理,48例),两组干预周期均为6月,比较喂养方式、Latches评分、EPDS评分。结果研究组纯母乳喂养成功率(68.75%)显著比对照组(22.92%)高,P<0.05。研究组护理后Latches评分显著比对照组高,P<0.05。研究组护理后EPDS评分显著比对照组低,P<0.05。结论4C延续性护理管理可有效提高产妇产后纯母乳喂养成功率,减轻抑郁情绪,效果显著,值得借鉴。
