保定市大学生医疗保险制度运行探析 总被引:1,自引:0,他引:1
为帮助大学生顺利完成学业,保障大学生享有基本医疗卫生服务权益,国务院于2008年年底决定将大学生纳入城镇居民基本医疗保险试点范围。制度运行两年多来取得了可喜的成绩,也暴露出许多问题。通过对保定市六所高校在校生进行问卷调查,发现问题集中表现为:大学生对制度了解较少,参保率低,学校医疗机构服务质量差、效率低,制度保障范围狭窄,转移接续难等。本文将根据分析结果,阐述问题根结所在,并试提出解决方案。目的是使大学生医疗保险制度真正能提高大学生的医疗福利水平,减轻大学生的医疗费用的负担。 相似文献

油气行业坚持创新驱动发展,将技术创新摆在了核心位置,也是实现能源“十三五”规划的重要保障.油气技术创新的关键点在于油气技术价值化,油气技术价值化是油气技术创新的内在需要和外在表征.提出推进油气技术价值化的战略管理思路,油气技术价值化需要经历“油气技术有形化—油气技术价格化—油气技术商业化”的路径.油气技术有形化以油气技术创造和油气技术确权为前提,油气技术价格化以油气技术价值评估和油气技术定价为基础,油气技术商业化以油气技术交易和油气技术运营为途径,综合构成油气技术的价值实现与价值增值过程. 相似文献

Innovation researchers have thoroughly discussed how attitudes toward innovation influence people's intentions to use it. Most prior research tried to explore employees' acceptance of technological change through the lens of change initiators; however, using a manager's or the “great man's” perspective to explain change recipients' reaction to an innovation is indirect and peripheral. This paper argues that innovation should be studied directly from the perspective of change recipients, and that their perceptions of fairness in the wake of an innovation become a key factor in their willingness to accept it. More specifically, this paper argues that the recipients' fairness perceptions mediate the impact of innovation characteristics (operationalized as “usefulness” and “ease of use”) and implementation approach on their acceptance and belief in the legitimacy of the innovation. Two studies investigated the hypothesized mediating effects of procedural fairness/outcome fairness. The field study was conducted in a real‐world technological innovation setting, but raised questions about whether the causal effect of the mediating model really existed. The scenario study was conducted in a semi‐experimental condition which had high internal validity and guaranteed the cause–effect relation. Hence, the research design of the two studies complemented each other. The multiple regression analyses using the criteria proposed by Baron and Kenny were used to test the mediating models in the paper. Moreover, both Sobel tests and bootstrapping methods were used to guarantee that the mediating paths do exist among the independent variables, mediators, and the dependent variables. Both the field study and the scenario study showed that most of our hypotheses were supported, and change recipients had strong psychological reactions to the innovation and how the innovation was implemented in terms of fairness perceptions. Change recipients' perception of procedural and outcome fairness mediated the impact of innovation characteristics and implementation approach on their acceptance of the innovation and the perceived legitimacy of the innovation. The results disclosed that the change recipients' fairness perceptions were a key step for their sense‐making process of an innovation and its implementation. The results also indicated that studying change from recipients' perspective, as well as trying to understand their fairness perceptions, can broaden our knowledge about change. Other theoretical and practical implications were also discussed. 相似文献

Employees of a certain rank are motivated by the pay gap between them and the levels above (upward comparison), and the pay gap between them and the levels below (downward comparison). In some cases, employees face multiple upward comparisons such as immediate and subsequent upward comparisons. We hypothesise that upward comparison matters more than downward comparison, and in the case of multiple upward comparisons, the immediate one matters more than the subsequent ones. We also hypothesise that the pay gap effect resulting from the upward/downward comparison ought to be non‐linear in that performance increases with pay gap size at a decreasing rate. The results from two empirical studies, namely, a longitudinal field study and a laboratory experiment, largely support our hypotheses. 相似文献
