建立符合医疗行业特点的激励机制是深化医药卫生体制改革的重要内容。医疗服务的特殊性要求服务提供者在提供医疗服务的过程中更多地考虑患者的健康福利,体现利他性。既能增加医疗服务提供者的动机和努力水平,又能维护其利他行为的激励机制成为改革的难点。激励机制的构建首先要明确有利于实现这一目标的激励要素和激励方式。实验研究作为可行的方法和工具,近年在激励要素和激励机制的研究中得到广泛运用。本研究总结了国内外医疗服务提供者激励要素和激励机制相关实验研究,以期为完善供方激励机制提供科学依据。

研究了近断层地震条件下,使用弹塑性减震索和黏滞阻尼器组合体系进行横向减震的斜拉桥的地震响应和减震规律.采用等效脉冲模型对实际近断层地震进行最小二乘拟合.人工合成Ⅱ类场地下的模拟近断层地震波3组,以永宁黄河大桥为工程背景,对人工近断层地震输入进行非线性时程分析,得到在不同脉冲周期的近断层地震作用下,减震措施设计参数对于塔梁相对位移等响应的影响.结果表明,拟合近断层地震下结构响应与实际地震相差较小,可以满足工程计算需求;近断层地震易造成大位移响应,弹塑性索参数设计时应使结构周期避开脉冲周期;容许减震索进入塑性与保持弹性相比,塔梁相对位移并不会明显增加,甚至在一些情况下会减小.

Objective This study estimated the investment in child development from three aspects-public health, public education, and family investment to establish the level of investment, to provide reference information for government decision making and to provide international comparisons. Methods Public investment in health was measured with macro data related to public health spending and child development in government expenditure. Public education investment was based on basic education data. Family investment evaluation was based on per capita family consumer spending data in different age groups to estimate the input for child development. Results Both public health investment level and the proportion of GDP rose for all age groups over time, but the overall investment level was still insufficient. Public investment in children＇s education has increased year by year, but the trends in all age groups are unbalanced with much lower investment in early childhood education. Private investment in children has increased over the period, but has declined as a percentage of GDP. International comparisons show that China＇s investment in child development is much lower than OECD countries. Conclusion The private investment in child development was the main way in China, with public finance contributing only a small proportion. Given the poor international comparisons, the government needs to review the balance of public investment to redirect more towards the development of children under the age of six to their health and education.

传统的QoS保障的单播路由算法都假设IP网络结点的状态信息可以被准确地获知,但实际网络存在许多因素使得状态信息非精确。所设计的改进算法是通过动态确定k优路径算法(k_shor-test algorithm)中的k值,从而确保最终求得的路径相对其他算法所求得路径是更优的。因此能有效地降低了丢包率,提高了端到端延迟绑定的概率,通过网络仿真器NS的仿真分析,结果表明了该算法的有效性。

随着叙利亚局势趋稳,其战后重建工作成为俄罗斯对外政策的重心之一。俄罗斯参与叙利亚国家重建主要出于以下动机:服务其世界大国的全球战略,塑造有利于俄方的中东地区秩序,巩固战后利益。为此,俄罗斯分别在安全、政治、经济三个领域采取了各种支持叙重建的举措,如多边维和与协助安全机制重建,推动宪法委员会组建及运行,提供国际援助等等。这些举措具有明显的俄式特征,即务实主义的理念、多边主义方式、军事力量为依托。然而,由于重建难度加大、能力不足、意愿下降、大国博弈加剧等,俄罗斯参与叙利亚重建的效果、前景具有复杂性和不确定性。
