近年来社会主义意识形态研究综述

社会主义意识形态研究,是关系党和国家事业全局的重大问题,也是学术界关注的重点。近年来,学术界在马克思的意识形态思想研究、对列宁意识形态理论的总体把握、社会主义核心价值体系研究、社会主义意识形态建设的创新性研究等方面,取得了显著成绩。但某些基本问题仍有继续探讨的空间:学术界还缺乏对"社会主义意识形态"内涵的清晰界定,缺少对关键问题和基础性问题的深度思考。

New Shrinkage Parameters for the Liu-type Logistic Estimators

The binary logistic regression is a widely used statistical method when the dependent variable has two categories. In most of the situations of logistic regression, independent variables are collinear which is called the multicollinearity problem. It is known that multicollinearity affects the variance of maximum likelihood estimator (MLE) negatively. Therefore, this article introduces new shrinkage parameters for the Liu-type estimators in the Liu (2003) in the logistic regression model defined by Huang (2012) in order to decrease the variance and overcome the problem of multicollinearity. A Monte Carlo study is designed to show the goodness of the proposed estimators over MLE in the sense of mean squared error (MSE) and mean absolute error (MAE). Moreover, a real data case is given to demonstrate the advantages of the new shrinkage parameters.     

印度对中印跨境河流水关系的认知及战略选择

近年来,印度对中印在跨境河流水关系中的不平衡问题非常重视.其中,水文信息不对称以及收益不平衡是印度对水关系不平衡的两个主要认知.基于中印边境的互动历史,印度在对水关系的认知形成中往往会夸大中国的敌意与威胁.据此,印度试图通过建立制度框架、将中印水争议国际化以及竞争性开发跨境河流水资源的战略思维,平衡中国在雅鲁藏布江—布拉马普特拉河水关系中的优势地位.然而受水外交两面性特征和内政的掣肘,印度平衡战略的影响有限,而且更强化了其对雅鲁藏布江—布拉马普特拉河战略安全收益的重视,并使未来中印双方基于水资源共同利益进行合作的难度加大.     

加强医院青年文化建设初探——以广西医科大学第一附属医院为例

如何加强医院青年文化建设,引导青年成才,促进青年在医疗事业中发挥更重要的作用,已经成为医院发展面临的一项新课题。针对医院青年文化建设存在的引导方式陈旧、活动组织困难、活动同质化等问题,应坚持先进文化的前进方向,用社会主义核心价值观引领青年文化建设;加大投入,加强激励,贴近实际,加强文化阵地建设,活跃青年文化生活;加强引领与品牌管理,构建特色品牌文化体系;强化医学人文精神,倡导职业文明。     

现代化进程中民族文化的嬗变与和谐民族文化的构建

在现代化进程中,民族传统文化遭受到前所未有的巨大冲击,发生了三种类型的嬗变,这是一个动态调整的过程,其结果是使民族文化适应现代化的发展方向,发生嬗变后的民族文化不同于和谐民族文化。现代化进程中民族文化的嬗变,可以说是一个被动的适应过程;构建和谐民族文化,可以说是一个主动的追求过程,它以发生嬗变的民族文化为基础,积极倡导民族和谐的价值取向,为构建和谐民族以及和谐社会提供智力支持。     

Approximation strategy-proof mechanisms for obnoxious facility location on a line

In the facility location game on a line, there are some agents who have fixed locations on the line where an obnoxious facility will be placed. The objective is to maximize the social welfare, e.g., the sum of distances from the facility to all agents. On collecting location information, agents may misreport the locations so as to stay far away from the obnoxious facility. In this paper, strategy-proof mechanisms are designed and the approximation ratio is used to measure the performances of the strategy-proof mechanisms. Two objective functions, maximizing the sum of squares of distances (maxSOS) and maximizing the sum of distances (maxSum), have been considered. For maxSOS, a randomized 5/3-approximated strategy-proof mechanism is proposed, and the lower bound of the approximation ratio is proved to be at least 1.042. For maxSum, the lower bound of the approximation ratio of the randomized strategy-proof mechanism is proved to be 1.077. Moreover, a general model is considered that each agent may have multiple locations on the line. For the objective functions maxSum and maxSOS, both deterministic and randomized strategy-proof mechanisms are investigated, and the deterministic mechanisms are shown to be best possible.     

Mediation Role of Dyadic Coping on Parenting Stress and Relational Resilience in Couples

This study aims to explore the mediating role of dyadic coping between relational resilience and parenting stress on married couples. The study participants comprised 229 married couples with at least one child and who have had a major life event. The relational resilience scale, parenting stress inventory, dyadic coping scale and personal information, and life events forms were used to collect data for this study. Data were analyzed with the actor–partner interdependence mediation model. The results revealed that dyadic coping actor–partner effects did not mediate between relational resilience and parenting stress. The results were discussed in relation to the social-ecological model and relevant literature. Based on the current findings, recommendations and implications for further research and practice were also proposed.
