社会福利视角下我国少儿教育的区域均衡:现实状况与未来走向     

万国威 《教育科学》2012,28(2):17-23

少儿教育的区域均衡研究一直以来主要采取教育学的分析视角,而本研究希望从社会福利学的角度去考察该问题。在利用SPSS软件中的聚类分析、因子分析、回归分析等技术对我国31个省份2004年到2010年的少儿教育福利供应状况进行研究之后,研究认为我国各省市的教育福利供应在发展水平具有较强的区域分化,且当前的教育福利政策并没有能够有效的缩小区域之间的既有差异。本文希望在对区域差异进行综合讨论的前提下,明确提出我国各个省市在教育福利未来建构中的基本类型。  相似文献   

纵向整体—分段连接:师范生语文教师专业技能训练体系     

张芹 《教育与教学研究》2012,(12):5-8

师范生语文教师专业技能"纵向整体—分段连接"的训练体系,是在"大语文教育"观和"整合连贯型"教师教育培养模式的背景下产生的,是对以往诸如"横向整体—学科渗透"训练体系的补充。其内涵是:注重语文教育教学作为一个整体却又具有小学、初中、高中的阶段特征,将师范生语文教师专业技能训练中的这三个阶段全面贯通、整体融合。培养既能承担小学语文教学,又能承担初中、高中语文教学的高素质语文教学师资。  相似文献   

经济史研究的新路径——《政治与经济之间——中国经济史专题研究》读后     

赵志浩 《江西教育学院学报》2012,33(5):11-14

以专著《政治与经济之间》研究特点为例,论证"政治-经济史"研究进路之必要及"以点带面,小题大做"研究方式之可行。经济与政治之间的密切关联表明:中国经济史研究不可撇开国家政权因素。高水平的研究一般都很重视研究方法,为避免经济史研究中的大而无当及空泛现象,需要运用历史"回溯"法找到恰当的切入点,以切入"点"带出纵向横向诸多层面的问题。运用"以点带面,小题大做"的研究方法要求研究者"主体"端正态度、提高学养,既要"苦读",亦要"深思"。  相似文献

《湘报》及其转载新闻报道研究     

柴莉 《商洛学院学报》2012,26(6):90-94

为分析《湘报》及其转载各类新闻报道的内容及其意义,对原始文献进行考证和统计,结果表明,《湘报》是戊戌维新运动时期资产阶级维新派在湖南长沙创办的一份以言论为主的报纸,同时也大量转载了国内外其他权威媒体的新闻消息和评论,主要包括时事政治新闻、新闻时事评论、自然科技新闻和商务经济新闻等。《湘报》转载的新闻报道对当时湖南整个社会风气的开化和推动湖南近代化进程起到了重要的作用。  相似文献   

《利济学堂报》与其农学知识传播     

刘小燕 《商洛学院学报》2012,26(2):80-87

为厘清《利济学堂报》（1897）中关于近代农学知识的传播脉络,认识其对近代农业的指导意义及地位。采用传播统计和原始文献分析方法,统计了《利济学堂报》中涉及农学知识的篇目,共57篇文章,并归为农政、蚕桑、农作物、园艺、土壤肥料、植物保护、农贸、农产制造、农具等12个子类目。其中,蚕桑、农政、农作物、农产制造、土壤肥料五类所占比重较大,占所有文章的72%,并对所有类目作了内容分析,了解各自的发展态势,进而掌握农业这一整个学科的概貌。《利济学堂报》中分门别类的农学知识几乎囊括了现代农学的二级次生学科,为之后专业性农业期刊《农学报》的诞生提供了重要的学科分类标准及信息来源,＂农学琐言＂专栏的设列充分表明该刊认识到农业知识的重要性,为其后专业性农业科技期刊《农学报》的产生作了良好的铺垫作用。  相似文献   

Library Statistics: The Russian National Standard     

Alexander Dzhigo 《Slavic & East European Information Resources》2013,14(3):141-148

Goals for developing the Russian national standard GOST 7.0.20—2014, System of Standards for Information, Librarianship, and Publishing: Library Statistics: Indicators and Units of Calculation, were to create lists of statistical indicators for library and documentation activities and to establish the statistical units for measuring those activities. The regulations included in the new standard will improve Russian library statistics, since its indicators cover all areas of modern library work. Unified indicators and units of calculation will promote uniformity in the primary statistical data submitted. Such uniformity facilitates accurate comparison and analysis for planning, accounting, and forecasting.  相似文献   

CONTENTdm Digital Collection Management Software and End-User Efficacy     

《Journal of Web Librarianship》2013,7(2-3):339-379

ABSTRACT

Digital libraries and collections are a growing facet of today's traditional library. Digital library technologies have become increasingly more sophisticated in the effort to provide more and better access to the collections they contain. The evaluation of the usability of these technologies has not kept pace with technological developments, however, and the end-user has in some cases been left behind. This research study evaluates the usability of digital collections created using the CONTENTdm Digital Collection Management System, a software system used by the University of North Carolina at Chapel Hill. Specifically, this study addresses the following questions: Does CONTENTdm meet users' needs? Is the interface sufficiently intuitive for them to use it? Is the experience of exploring digital collections using CONTENTdm satisfying to users? Employing usability testing techniques with actual-end users, this study attempts to assess the efficacy of the CONTENTdm public interface as well as user attitudes toward it. Ten participants from three user groups—faculty, library science graduate students, and the general public—performed eleven tasks designed to test the key functions of CONTENTdm-created collections and then answered a series of questions about their experiences. Key findings from this study indicate that while the included digital collections are useful and desirable to end-users, the interface generated by CONTENTdm can be confusing even for those who have considerable experience using the Internet. Results from this study may be used to improve this software system and add to the literature surrounding the usability of digital libraries in general.  相似文献   

EP-based adaptive tracker with observer and fault estimator for nonlinear time-varying sampled-data systems against actuator failures     

Jason S.-H. Tsai  Chao-Lung Wei  Shu-Mei Guo  Leang S. Shieh  Ce R. Liu 《Journal of The Franklin Institute》2008,345(5):508-535

An evolutionary programming-based adaptive observer is presented in this paper to improve the performance of state estimation of nonlinear time-varying sampled-data systems. Also, this paper presents a novel state-space adaptive tracker together with the proposed observer and estimation schemes for nonlinear time-varying sampled-data systems having actuator failures. For the class of slowly varying nonlinear time-varying systems, the proposed methodology is able to achieve the desired fault detection and performance recovery for the originally well-designed systems, as long as the controller having the high-gain property. For practical implementation, we utilize the advantages of digital redesign methodology to convert a well-designed high-gain analog controller/observer into its corresponding low-gain digital controller/observer. Illustrative examples are given to demonstrate the effectiveness of the proposed method. The developed digitally redesigned adaptive tracker with the proposed observer and estimator is suitable for implementation by using microprocessors.  相似文献
