参加医疗保险对农村居民健康的影响——基于CHARLS 2015数据的实证分析

基于CHARLS 2015数据,采用倾向得分匹配法实证分析参加医疗保险对农村居民健康的影响。研究发现:参加医疗保险对农村居民的日常活动能力和自评健康影响不显著,参加医疗保险对农村居民认知能力具有显著的正向影响。据此提出,应进一步提升社会医疗保险保障水平、扩大社会医疗保险保障范围、促进商业医疗保险有序发展、推进"三医"高效协同联动等,以充分发挥医疗保险的健康保障功能,从而进一步提升参加医疗保险对农村居民健康的正向影响。     

The importance of cross‐disciplinary scientific engagement in the development of quantitative procedures for aggregate safety assessments

Recent guidance on safety monitoring during drug development, issued by regulatory authorities in the United States and European Union, indicate a shift in focus towards aggregate safety monitoring and scientific evaluation of integrated safety data. The call for program‐level reviews of accumulating safety data, including from ongoing studies, provides an opportunity to leverage the scientific expertise and medical judgment of safety management teams with (a) a multidisciplinary approach, (b) quantitative frameworks to measure level of evidence, and (c) assessments that are product‐specific and driven by medical judgment. A multidisciplinary team, regularly reviewing aggregate safety data throughout the development program, is vital not only for early signal detection but also for generating a better understanding of the accumulating data and context needed for decreasing false alarms.     

万物互联时代的“算法”崇拜与资源配置变革

随着万物互联时代的来临，人类资源配置将被各种人工智能“算法”①所取代。万物互联产生的数据将成为社会资源的重要形态，也是支撑人工智能“算法”的重要基础。数据资源的安全、所有权归属、开发利用效率以及保密等重要议题，将成为民族学、经济学、社会学和心理学等相关学科关注和研究的新热点。我国是一个统一的多民族国家，如何将丰富的民族多样化资源转化为支持万物互联资源网络协同优化配置人工智能“算法”的数据，需要从民族历史、文化、生物、信息处理技术等相关学科做深入的理论和实证研究。在万物互联时代，因资源配置方式与配置机制发生变革，经济学一般不再直接求解资源最优配置的策略集，更多是从理论和实证方面研究资源配置中人工智能“算法”的构造原理、构造条件与影响因素。万物互联时代，社会和谐秩序的构建，需要政府建立和维护万物互联网络的安全防护体系，并对资源配置中人工智能技术演变路径作规范和指引。     

企业资源配置战略与盈余持续性

盈余持续性是盈余质量的重要特征。较高的盈余持续性预示着企业的盈余质量较高,在一定程度上表明企业的经营状况平稳并具有良好的管理水平,有利于企业降低经营风险、提升公司价值。近年来,盈余持续性已经成为资本市场研究领域的一个热点问题。以我国A股市场2007—2017年非金融类上市公司为样本,对企业资源配置战略与盈余持续性之间的关系进行了实证研究。研究结果表明,经营主导型公司的盈余持续性要显著强于投资主导型公司;进一步区分具体的盈余构成后发现,经营主导型公司核心利润的持续性显著强于投资主导型公司,但其投资收益的持续性显著弱于投资主导型公司。上述结论表明,盈余及其构成的持续性均会受到公司资源配置战略的影响。相关研究结论既为公司资源配置战略影响盈余特征提供了经验证据,又对外部利益相关者透过战略本质看清会计信息的内在价值具有一定的启示作用。     

Testing the gender similarities hypothesis: differences in subjective task value and motivation to transfer training

ABSTRACT

Are female and male trainees similar or different in their reaction to training programmes, specifically regarding their subjective task value and motivation to transfer? According to the gender similarities hypothesis, women and men are alike on most psychological variables. However, according to research in organizational behaviour, female and male employees differ on certain aspects, such as their job satisfaction and work identity. To test these two views on gender similarities and differences in the context of human resource development and training evaluation, the present study examined the extent to which gender moderated reactions to training. Based on the expectancy-value theory of motivation and self-determination theory, a web-based questionnaire was used to measure six training reactions: intrinsic value, attainment value, utility value, perceived relative cost, autonomous motivation to transfer, and controlled motivation to transfer. The results indicated that women and men differed in their ratings of attainment value but were similar for the remaining five reaction measures. These outcomes support the gender similarities hypothesis. The findings are discussed in terms of their theoretical implications for modelling gender effects in HRD research and their practical significance for promoting training effectiveness and transfer of training.     

Surgical Identity Play: The Anatomy Lab Revisited

The anatomy lab has been studied by sociologists interested in professional socialization since the 1950s. This is because the act of dissecting a cadaver is thought to be foundational for both the student's medical knowledge and the development of the student's professional identity. In this paper, I revisit the anatomy lab both historically and ethnographically. Drawing on theoretical insights from the laboratory ethnography tradition within science and technology studies, I show that students use material artifacts in the lab to support their “surgical identity play.” This activity is structured by the laboratory's performative architecture even while it is unsupervised by anatomy faculty. While many analyses of professional socialization focus on how students learn to interact with patients during their training, I show that the anatomy lab experience is an important form of professional socialization because here students learn to employ surgical instruments, language, and dress, and begin to relate to each other as colleagues.     

规模化生猪养殖污染防治的现状与政策启示——基于养殖户调查数据的实证分析

基于规模化生猪养殖户的问卷调查数据,归纳和界定规模化生猪养殖污染防治行为的内涵,并进一步通过单因素方差分析和交叉分析研究规模化生猪养殖污染防治行为的群体差异。研究发现:规模化生猪养殖的污染防治行为具有多维性且总体实施情况一般;其无害化处理行为的群体差异显著,资源化利用行为的群体差异部分显著。据此,应进一步强化源头治理以提高污染防治的执行能力、加强过程监控以提高污染防治的规范水平、重视末端利用以推进污染防治的综合利用,从而有效改善规模化生猪养殖污染防治政策的实施效果。     

Sharing and exchanging: understanding common grounds in northeast India

ABSTRACT

Northeast India, a ‘zipper region’ that gives impetus to Southeast Asian and Himalasian studies, is marked by complexities and ambiguities. The paper examines the multiple identity construction in contemporary Assam, the central state of this region and seeks to recover the other experiences that make ethnic life-world possible while challenging the ethnocentric discourses—in academia, politics, public and social movements. Acknowledging the presence of common or possibly universal processes behind the production of such discourses, it aims to interrogate the factors that cut across socio-cultural, political-economical or ecological dimensions. It further examines the multiple discourses and narratives that makes that social possible in the region. In doing so, it locates the strategic positioning of such discourses and how they deal with Indian nation-state and beyond. This paper in essence is interested in the question of possibility of various discourses—as a question of post-history.

中国基本医疗保险的实际参保率及其分布特征:基于多源数据的分析

全民覆盖是基本医疗保险降低国民医疗费用负担的前提条件。中国基本医疗保险是否实现了全民覆盖仍存在争议。本文利用多源调查数据,分析了我国基本医疗保险实际参保率及其分布特征。不同来源的数据基本证实,2015-2016年,中国仍有超过10%的国民没有参加任何一项基本医疗保险制度。其中,城镇居民、非农户口和没有户口的居民、东北地区、年轻人、儿童、未就业人群、低收入人群、在校学生以及流动人口基本医疗保险实际参保率更低。城乡居民实行自愿参保,因管理部门分割、信息系统不统一导致的重复参保以及因财政补贴制度导致的户籍地参保等制度设计,是导致基本医疗保险未能实现全民覆盖的根源。要实现基本医疗保险全民覆盖,解决国民医疗后顾之忧,未来我国基本医疗保险应实行强制参保、以家庭为单元参保、常住地参保,建立全国统一的基本医疗保险信息系统,并鼓励发展补充性医疗保障制度。
