论民族教育的“依法治教”及教育事业健康发展

现行民族教育法律制度理论准备有所不足,民族教育立法欠完善,可操作性差。应当正确认识和重新界定“消灭三大差别”的科学内涵,深入调研,转变观念,建立适合我国民族地方条件与民族特点、有利于民族文化传承创新的新的教育模式,制定实施《民族教育法》,促进民族教育“依法治教”和教育事业健康发展。     

二氧化钛纳米膜制备条件对炼焦厂废水光催化降解性能的影响

以四氯化钛为前驱体,用溶胶—凝胶法制备了TiO2纳米膜,并进行了炼焦厂废水的光催化降解实验,考察了制备条件对其光催化降解性能的影响。结果表明最佳工艺条件为:四氯化钛∶乙醇∶水=30∶400∶25,溶胶体系pH=7,掺铁量Fe∶Ti=0.16,干凝胶在450℃煅烧2h,由此制成的TiO2纳米膜光催化降解炼焦厂废水的降解率超过79%。     

Pathways between education and health: a causal modelling approach

Summary.  The association of poor education and poor health has been consistently observed in many studies and in various countries. Thus far, studies examining the mechanisms underlying this association have looked at only a limited set of potential pathways. This study simultaneously examines six distinctive pathways, which have been hypothesized to link education and health and found support from previous studies. A causal analysis of education and health was performed using structural equation models. Data were used from six phases of the National Child Development Study, which is based on following up an initial sample of 17416 children who were born in 1958. The association between education and health appears to be explained by a combination of mechanisms: adolescent health and adult health behaviours for men and women, adult social class among men and parental social class among women. We conclude that improvements in population educational attainment may not automatically lead to improvements in population health, and that health policies for improving health and reducing health inequalities need to target specific causal pathways.     

坚持以人为本,树立科学的人才教育观

树立科学的人才教育观,对于现代人才教育有着重要意义,是社会和时代发展的需要。我们要在邓小平理论和“三个代表”重要思想的指导下,实事求是、求真务实地抓好人才教育,为国家和社会的发展服务。     

“国培计划”培训团队建设政策的反思与改进--基于政策工具与政策要素的二维分析

培训团队建设是实施“国培计划”的基础工程,是保证“国培计划”实施质量的关键所在。“国培计划”培训团队建设政策是引领“国培计划”培训团队建设实践的重要依据。以2010-2019年“国培计划”培训团队建设政策文本为研究对象,基于政策工具与政策要素的二维分析框架展开研究。研究发现,“国培计划”培训团队建设政策经历了“建章立制”(2010-2012年)、“稳步发展”(2013-2014年)、“精准推进”(2015-2019年)三个阶段,呈现出政策工具差异化、团队成员多元化、运行机制精准化等特征,同时也暴露出政策工具运用失衡、团队建设目标不清晰、相关政策难以有效落地等问题。因此,“国培计划”培训团队建设要注重优化政策工具结构、明确团队建设目标、坚持因地因时制宜,进一步提升政策的长效性、持续性和精准性。     

Information and communications technologies, strategic asymmetry and national security

In the history of warfare, there are a number of examples of strategic uses of asymmetric technologies. Consistent with history and theory, individuals, organizations and nations have spotted opportunities to employ information and communications technologies to gain and exploit asymmetric advantages and to counter asymmetric weaknesses. This article discusses various asymmetries associated with institutions, nations and organizations that influence the ICT-national security nexus. Regulative, normative and cognitive institutions in a country provide various mechanisms that affect the nature of positive and negative asymmetries. Nations and organizations also differ in terms of their capability to assimilate ICT tools to gain positive asymmetries and deal with vulnerabilities of negative asymmetries. Integrative approaches that combine policy and technological measures at various levels are likely to make the world more secure.
