加强临床医学研究生临床能力的培养与管理

临床能力的培养在临床医学硕士专业学住研究生培养过程中尤为重要.针对研究生入学前临床基础参差不齐的状况,学院在教学管理实践中不断强化研究生临床意识,加强临床能力的培养,规范临床能力的考核,重视临床和科研能力的实践,制定了具体的培养方案和质量管理办法.     

组织人格的形成原因及作用探讨

通过梳理组织人格形成的原因:组织核心价值观、领导风格、组织所在行业特征、组织形象塑造,以及组织人格作用的三个结果变量:员工满意度、顾客满意度、公众满意度,初步构建出组织人格研究的理论模型,为进一步的研究奠定了基础.     

Network public goods with asymmetric information about cooperation preferences and network degree

We propose a game theoretical model of one-shot network public goods formalizing the ‘closure argument’ that cooperation is more frequent in denser groups or networks. Equilibrium analyses show that (i) an ‘inefficiency problem’ exists: players all preferring mutual cooperation need not all cooperate; (ii) in dyads, groups and networks with degree independence, first order stochastic dominance shifts of the distribution of cooperation preferences or the degree distribution (weakly) increases cooperation, and (iii) the latter result does not hold for networks with degree dependence. Hence the closure argument always holds in networks satisfying degree independence but not in other networks.     

A Fixed Point Approach to the Classification of Markov Chains with a Tree Structure

In this paper, we study the classification problem of discrete time and continuous time Markov processes with a tree structure. We first show some useful properties associated with the fixed points of a nondecreasing mapping. Mainly we find the conditions for a fixed point to be the minimal fixed point by using fixed point theory and degree theory. We then use these results to identify conditions for Markov chains of M/G/1 type or GI/M/1 type with a tree structure to be positive recurrent, null recurrent, or transient. The results are generalized to Markov chains of matrix M/G/1 type with a tree structure. For all these cases, a relationship between a certain fixed point, the matrix of partial differentiation (Jacobian) associated with the fixed point, and the classification of the Markov chain with a tree structure is established. More specifically, we show that the Perron-Frobenius eigenvalue of the matrix of partial differentiation associated with a certain fixed point provides information for a complete classification of the Markov chains of interest.     

社区公共服务对老年人幸福感的影响

本文基于中国老年健康影响因素跟踪调查(CLHLS)2018年数据,运用Ordered probit模型和工具变量条件混合过程估计法(CMP方法)考察社区公共服务对老年人幸福感的影响。研究表明,社区公共服务完善程度对老年人幸福感具有显著的促进作用,且这一影响具有明显的城乡、独居养老成因和年龄异质性。社区公共服务匹配度对社区公共服务的老年幸福感效应具有明显调节作用:社区公共服务匹配度越高,社区公共服务对老年人幸福感的促进作用越强。因此,构建以社区为依托的多层次养老体系不仅要着力完善社区公共服务,更要重视社区公共服务供给与老年居民真实需求间的精准匹配,以在提升资源利用效率的同时更好地发挥社区公共服务对老年居民福祉的促进作用。
