论高等师范教育实践课程的变革

高师现行沿用的教育实践课程制度存在课时总量不足 ,学科课程与实践课程比例失衡 ;以教育实习为主 ,形式单一、实践与理论隔离、内涵缺失等问题。由此出发 ,教育实践课程改革应在以下层面进行 :增加教育实践课程课时总量 ,使学科课程与实践课程取得动态平衡 ;形成多阶段、多形式的教育实践内容体系 ;整合理论与实践 ,创生新的教育实践模式 ;更新评价理念 ,合理运用多种评价方式。同时 ,教育实践课程改革还要特别关注硬件和软件建设。     

大力发展农产品加工业提高农业市场竞争力

加入WTO后,我省的农业结构调整进入了根本性变革的新阶段,除从农业内部着手外,更需要从农业之外寻找出路.做大做强农产品加工业将提高我省农产品竞争能力,农产品加工业的大发展将担负起优化结构,增加收入的历史重任.而要发展农产品加工业,必须实现六个方面的突破.     

货币政策调控有效性的实证检验

应用平稳性检验、协整性检验与因果检验,分析货币政策对经济政策与物价变动的影响,以此检验货币政策的有效性。实证结果表明,金融变量与经济增长、物价变动之间存在着长期稳定的因果关系,特别是80年代以来推行的市场经济改革,增强了中央银行选择货币供应量作为中介指标的可操作性,中央银行可通过控制货币供给总量来影响宏观经济活动,达到间接调控的目的。     

和谐社会建设中低收入群体社会心态的引导与调适

良好的社会心态既是构建社会主义和谐社会的一种内在要求，也是和谐社会建设的重要心理资源。在社会转型时期，由收入差距扩大引起的不公平感和社会生活中的焦虑感，使低收入群体遭受到物质和精神上的双层困扰，并产生政治上的冷漠心态和信仰上的迷茫，为此，需要在社会意识领域做好教育疏导工作，更要在社会存在领域做好良好社会心态的强本固基工作。     

基础教育非均衡发展的政策透视

从教育政策的视角来透视我国基础教育非均衡的现状,可以发现在形成基础教育非均衡发展过程中存在着教育政策价值取向的“城市偏好”、教育资源配置政策、教育绩效评估政策和“重点学校”政策等多层面上的错位。当前对基础教育政策的调整可以通过以下途径来实现:强化基础教育公平的价值理念,突显弱势补偿原则;实行教师交流制度,完善教育优质资源的共享机制;建立科学的督导评估体制;取消“重点学校”政策,推行学校标准化制度等。     

财政分权、产业结构调整与绿色全要素生产率——基于环境污染门槛效应的视角

基于财政分权下政府与产业结构调整的策略博弈,从理论模型分析了政府产业引导与产业自身调整间的非合作博弈的发生、造成产业结构调整在绿色全要素生产率上的异质化效应,并应用2004—2017年间中国省级面板数据,采用动态面板门槛模型进行了实证检验。研究结果表明:当环境污染程度较低时,财政分权的施行将有助于产业结构调整带动绿色全要素生产率提升;当环境污染程度较高时,财政分权的施行将不利于促进产业结构调整带动绿色全要素生产率提升;财政分权主要通过税收竞争与财政环境补贴和支出双重路径影响产业绿色全要素生产率的提升。借此,对在区域财政分权背景下动态调整区域财政体制与产业绿色发展转型提出了相应的建议。     

基于可变参数优化的相关证据合成方法研究

总结了相关证据合成的理论方法,分析了已有合成方法的不足,对相关证据的相关焦元 的分布情况进行了分析,提出一种面向问题的基于可变参数的相关证据的合成方法. 方法只对 相关焦元的基本可信数进行修正,克服了对相关证据所有焦元进行修正的弱点,使修正的对象 更加合理,修正系数可用基于学习的寻优方法得到. 在相关证据的相关焦元的基本可信数未知 的情况下也可进行相关证据的合成. 计算结果表明该方法对合成的结果有明显的改进     

Connecting for success: Egocentric network types among underrepresented minority students at college

This study investigates the egocentric networks of underrepresented minority students. Adjustment to college for underrepresented minority students often means balancing between the origin (i.e., low-status family) and host (i.e., academic) environments, requiring students to develop different coping strategies. The analysis included 124 Roma university students. We employed the contact diary method and the EgoNet program for mapping students’ egocentric networks. We explored classification among egocentric networks by cluster analysis based on the network proportion of the origin, fellow, and host groups. Three clusters were distinguished. The Host-based cluster proved to be the most advantageous, while the Balancing cluster appeared to be the most disadvantageous in terms of network resources, well-being, and trust. Partners’ ethnicity and educational attainment showed a strong connection with cluster membership. Our results highlight that small fellow communities can successfully interconnect the origin and host groups in students’ egocentric networks.     

耶律阿保机对世选制的调整与利用

阿保机时代是契丹社会大变革的时代,阿保机变革旧制的一个内容就是对传统世选制的改造。经过他的努力,从理论意义上实现了契丹可汗世选向皇位世袭的转变,也对官吏的世选作了重大的调整。值得重视的是,阿保机的政治智慧在变革世选制过程中有所体现。     

Adjustment for nonresponse with variables from different sources: Bias correction and precision loss,with application to the Swiss European Social Survey 2012

ABSTRACT

Adjustment for nonresponse should reduce the nonresponse bias without decreasing the precision of the estimates. Adjustment for nonresponses are commonly based on socio-demographic variables, although these variables may be poorly correlated with response propensities and with variables of interest. Such variables nevertheless have the advantage of being available for all sample units, whether or not they are participating in the survey. Alternatively, adjustment for nonresponse can be obtained from a follow-up survey aimed at sample units which did not participate in the survey and from which the variables are designed to be correlated with response propensities. However, information collected through these follow-up surveys is not available for people in the sample who participated neither in the survey nor in its nonresponse follow-up. These two sets of variables when used in a nonresponse model for the Swiss European Social Survey 2012 differ only slightly with regard to their effect on bias correction and on the precision of estimates. The variables from the follow-up are performing slightly better. In both cases, the adjustment for nonresponse performs poorly.
