Rapid visual processing by college students in reading irregular words and phonologically regular pseudowords presented singly and in contiguity

Using normal adult readers, this study examined the relative involvement of magnocellular and parvocellular processes in reading English phonologically regular pseudowords and irregular words presented in isolation and in contiguity from left to right. The data showed that a low temporal frequency visual measure that implied more parvocellular involvement was active in processing irregular words presented singly and pseudowords presented in contiguity. However, the results failed to show the involvement of the magnocellular pathway (as implicated by low spatial and/or high temporal frequency visual measures) in reading words presented in contiguity from left to right. The discrepancy was discussed in terms of the sensitivity of the tasks used in testing the two pathways.     

Inclusive education in Spain: how do skills,resources, and supports affect regular education teachers’ perceptions of inclusion?

This study examined regular education teachers’ perceptions of inclusion in elementary and secondary schools in Spain and how these perceptions may differ depending on teaching experience, skills, and the availability of resources and supports. Stratified random sampling procedures were used to draw a representative sample of 336 general education teachers (68 kindergarten, 133 elementary, and 135 secondary teachers) from the province of Alicante. The results indicated the acceptance of the principles of inclusion, although teacher skills, time, material resources, and personal supports for inclusion were deemed insufficient. Kindergarten and elementary teachers showed more positive perceptions of inclusion than secondary education teachers, and so did teachers with more personal supports and material resources than those with less supports and resources. The results are discussed in terms of its implications for practice in order to promote more inclusive classrooms in Spain.     

普通高校女大学生中长跑调查分析与教学建议——以贵州省为个案

女大学生是高校的特殊群体,她们的健康备受全社会的关注.基于中长跑项目具有较大的健身价值和其在体育课中的重要地位,本文主要运用问卷调查法、数据统计法、文献资料法和逻辑分析法,通过对所抽样的贵州省8所普通高校在读女大学生对中长跑的体育态度和不喜欢中长跑原因进行了统计与分析,同时提出几点教学建议.     

教师定期流动政策执行的实证调查研究——基于政策工具视角

通过问卷调查对教师定期流动政策的执行过程进行实证研究,以政策工具理论为指导,基于政策工具视角对政策执行过程的实证调查进行分析与讨论.在优化政策工具方面从完善其管理环境、制度环境、监督环境着手,探索将政策意图转变为管理行为、将政策理想转变为政策现实的最佳工具,尤其是2011年重庆市《义务教育条例》颁布并逐步推行后,更需寻求使现有教师流动机制更高效、更完善、更有效的工具路径.     

墨西哥孔子学院发展特点、问题及对策

按照《孔子学院发展规划（2012—2020年）》,到2015年,我国将在全球建立500所孔子学院和1000中小学孔子课堂。墨西哥是拉美地区最早开设孔予学院的国家,也是孔子学院最多的国家,对其发展特点、存在问题进行探析并找出对策,可以对下一步孔子学院的建设提供一定的借鉴作用。     

具有脉冲药物治疗的乙肝病毒感染模型周期解的存在性与稳定性

讨论了一个具有脉冲药物治疗的乙肝病毒感染模型周期解的存在性与稳定性的问题,利用脉冲微分方程理论获得了一个无病周期解,并通过Floquet乘子定理证明了系统无病周期解全局渐近稳定的条件。     

圆曲线数字化时的模型不确定性

空间数据不确定性作为地理空间信息的一个理论问题,学术界对它的研究已开展了若干年。本文通过对规则曲线中圆曲线的模型误差分析,讨论了圆曲线数字化时最大偏距误差、各个点的模型误差、数字化时导致的面积误差,建立了圆曲线综合误差带的可视化模型。验证了数字化时模型不确定性基本上呈现出两头小、中间大的“纺锤形”特征。     

内部审计存在的问题与对策

内部审计监督是我国审计监督体系的重要内容.但从目前情况看,内部审计的作用并没有充分发挥出来,究其原因是由于诸多方面造成的.如何才能使内部审计的监督作用真正发挥出来并为单位经济管理和经济发展服务,是审计工作需要研究、探讨和解决的现实问题.     

News You Can Use or News That Moves?

This study investigates how journalists covering international humanitarian crises make decisions regarding what types of information to include in stories. Specifically, the inclusion/exclusion of solutions-oriented information is addressed, since crises represent a key time during which the potential for international engagement is discussed in the mainstream media. Interviews with journalists covering hunger crises in Africa reveal an internal tension between maintaining a neutral, unbiased position and writing in a way that supports engagement and action. Ironically, perhaps, journalists find that including solutions-oriented information amounts to unethical and biased coverage, despite the fact that inclusion of solutions to social problems is an accepted and institutionalized aspect of the US news media’s mandate to the public. Reasons for this seeming contradiction are discussed, and I argue that solutions-oriented information not only can be included without demonstrating bias, but that it ought to be included to support ethical coverage that properly informs citizens about potential paths for political engagement.
