本文比较了未来收回决策权情形下授权和信息传递的优劣。研究采用了两期模型,第一期委托人决定是否授权,第二期委托人根据第一期获取的信息做出决策。Dessein(2002)的单期模型表明,只要存在有效信息传递,授权总是占优于信息传递的均衡。但在两期模型中,如果第二期委托人收回决策权,则第一期信息传递可能占优于完全分离均衡下的授权。此时,授权导致行动偏离最优点过高,使得授权不一定适宜。此外,折现因子越高,授权导致的偏离越大。

扩内需促升级,是中国经济发展的重要战略选择。内需是国民经济总需求的主体,是大国经济发展的核心动力,必须把扩大内需摆在极为重要的战略地位;推动经济转型升级则是推动高质量发展的内在要求和必然选择。消费在扩内需促升级中发挥着日益重要的作用。随着城乡居民收入水平不断提高,消费者对高端商品的需求不断增强,高端消费成为消费市场的一个重要维度。疫情暴发后,中国居民境外购物活动大幅减少,使得更多的高端消费流向境内市场。但自2023年以来,出境旅游和海外代购等形式的消费活动逐渐复苏,中国高端消费外流问题再次引起学术界和业界关注。高端消费回流是扩大内需、促进经济增长和结构升级的重要举措。当前,高端消费回流面临品牌影响力不足、价格竞争力缺失、服务需求未能得到充分满足等多重挑战,应从提高境内市场供给质量和品牌影响力、发展免税经济降低价格成本和税收负担、提升市场服务水平和体验感、积极应对全球供应链问题和风险等方面发力,主动引导高端消费回流。

背景基层医疗卫生机构以其综合、连续、协调、便捷和经济的特点,扮演着儿童常见病、多发病诊疗、计划免疫以及儿童健康管理的重要角色,为儿童健康服务奠定坚实基础。开展家庭医生签约管理下的儿童保健服务,对于提升儿童健康服务质量至关重要。然而,我国基层机构在儿童健康服务能力方面存在地区差异,因此,准确评价基层儿童健康服务质量,有助于及时发现问题,推动基层儿童健康服务向更高水平发展。目的了解签约儿童家长对社区儿童健康服务质量的评价情况,分析质量问题,提出优化策略,为进一步提升社区儿童健康服务质量、推进儿童签约服务高质量发展提供决策参考。方法以成都市某区为案例地区,2022年采用方便抽样,抽取该区3家社区卫生服务中心为样本机构,采用初级卫生保健服务质量评价工具(PCAT)中文版,对样本机构签约儿童家长进行社区儿童健康服务质量在线问卷调查。结果共完成3631名签约儿童家长调查。样本机构社区儿童健康服务质量PCAT中文版总得分为(58.72±13.43)分。社区儿童健康服务质量PCAT得分相对较高的维度为“持续性”“社区首诊(服务可及性和服务使用)”以及“服务综合性(服务提供)”,而“以家庭为中心”“综合性(可用服务)”和“协调性(转诊)”等维度得分相对较低。不同户籍、文化程度、平均年收入、有无熟悉的医护人员和过去1年在该中心就诊次数的调查对象PCAT中文版总得分比较,差异有统计学意义(P<0.05);多元线性回归分析结果显示,调查对象的户籍所在地,母亲的文化程度、家庭平均月收入、有无熟悉的医护人员和过去1年在该中心就诊次数均是PCAT总得分的影响因素(P<0.05)。结论案例地区签约服务模式下社区儿童健康服务质量水平有较大提升空间,应重点加强社区儿童健康服务综合性(可用服务)和服务协调性(转诊),推动以儿童及家庭为中心理念落实,关注非本地户籍儿童健康服务工作。

目的本研究通过光遗传学技术特异性激活雄性Sprague-Dawley(SD)大鼠中脑腹侧被盖核投射至臂旁核多巴胺能通路(VTA DA-PBN),探究该通路在丙泊酚麻醉苏醒中的作用。方法将32只雄性SD大鼠随机分为ChR2+Light on组、ChR2+Light off组、mCherry+Light on组和mCherry+Light off组,每组8只。各组大鼠经尾静脉以11 mg·kg^(-1)剂量进行丙泊酚麻醉诱导,以48 mg·kg^(-1)·h^(-1)剂量麻醉维持30 min,记录翻正反射消失(LORR)和翻正反射恢复(RORR)时间;通过免疫荧光染色验证病毒注射部位;通过在体脑电(EEG)记录麻醉诱导和苏醒期间的皮层脑电变化。结果光遗传学激活VTA DA-PBN通路,LORR时间无统计学差异(P>0.05),RORR时间缩短(P<0.001);与mCherry组相比,ChR2组VTA中c-Fos蛋白表达明显更高(P<0.001);EEG结果显示:RORR期间,光激活组β波功率百分比高于光对照组(P<0.05),而δ波功率百分比低于光对照组(P<0.01)。结论VTA DA-PBN通路参与调控丙泊酚麻醉苏醒阶段,激活这一通路起到促觉醒作用。
