以图画为本位的文学--图画书的演变史

中国原创图画书开始走向世界,但中国图画书的历史可能比西方更早。图画书本质上是一种出版现象,在中西方不同文化背景中有不同的呈现方式。中西方图画书同源于儿童读物的插图,随着出版科技的进步和读图时代的到来,从“出版热”逐渐形成“文学热”,从“文字的儿童读物”演化为“图画书的儿童文学”,在新世纪交流融合中发展为儿童文学的典型样式——绘本。中国原创图画书的复兴有其深刻的历史文化背景和深厚的民族文学传统,建设中国特色的图画书评价标准和理论体系应该提上议事日程。     

How much does lower body strength impact Paralympic running performance?

Objectives: Development of evidence-based methods of Paralympic classification requires research quantifying the relative strength of association between ratio-scaled measures of impairment and athletic performance. The purpose of this study was to quantify the extent to which muscle strength affects running performance in runners with and without brain impairment. Design: Cross-sectional study. Methods: Participants were 41 male runners: 13 with brain impairments (RBI) and 28 non-disabled (NDR). All participants completed a maximal 60-m sprint and a novel battery of three lower limb isometric strength tests. Results: RBI showed significantly lower strength scores compared with NDR on the more affected side in leg flexion (176 vs. 243?N), leg extension (993 vs. 1661?N) and plantarflexion (824 vs. 1457?N). Significant differences were also seen on the less affected side in plantarflexion (1072 vs. 1508?N). RBI were significantly slower in the acceleration phase (0–15?m) (3.2?s?±?0.3?vs. 2.8?s?±?0.2) and top speed phase (30?60?m) (4.3?s?±?0.6?vs. 3.8?s?±?0.3). Correlation analysis showed stronger relationships between strength and running performance in RBI than NDR; however, the correlations were not significant. Conclusions: This study evaluated measures to assess strength for the purposes of classification and found that the measures were significantly different in RBI compared with NDR indicating the tests were able to capture strength impairment in this population. This study indicates that strength may be an important impairment type to assess in this population, as impairments of muscle strength may influence the outcome of running performance in athletes with more severe impairments.     

有机化学课程教学中的“一个中心”与“两个基本点”

在有机化学教学中，强调以“结构——性质”模式为中心，突出有机化学在学生专业中的作用和坚持理论教学与实验教学有机结合两个基本点，可以取得良好的教学效果。     

现代远程教育校外学习中心模式及对自学考试的启示

我国的现代远程教育经过近十年的发展,已经取得了很大的成绩。校外学习中心模式已经逐步建立起来,并已成为支撑远程教育的重要形式之一。校外学习中心模式吸收了国外开放大学学习中心模式的精髓,有着明显的中国特色。本文从"学习中心"的起源、职能、运行模式等方面对校外学习中心模式进行了全面的分析,并提出该模式对自学考试完善社会化学习支持服务体系在两方面有重要启示作用。一是,校外学习中心市场化的运作模式及其组织保障系统;二是,服务的思想和力度可以通过学习中心模式得到更好的实现和加强。     

If we build it,will they come? The effect of new athletic facilities on recruiting rankings for power five football and men's basketball programs

College athletics is currently in the midst of a building boom in which universities are competing with each other to reach an always-increasing standard of lavish athletic facilities. While these facilities are costing in the tens or hundreds of millions of dollars, little research is examining the return on investment for athletic programs. The purpose of this study was to examine the effect of new athletic facilities on recruiting rankings for Power Five football and men's basketball programs. Data was collected on athletic facilities newly constructed or renovated from 2005 through 2015 at Power Five NCAA Division I programs. Using LSDV fixed effects regression models, results found a lack of significant improvement within football and basketball recruiting rankings following the completion of new athletic facilities, but some significance in the two years before the project was completed. Significant control variables also highlighted the effects that coaching changes can have on recruiting.     

基于ERIC数据库的国外远程教育研究热点分析

以ERIC数据库收录2003至2010年间,经同行评审的有关远程教育的文献为数据样本,在确定国外远程教育研究领域49个高频主题词的基础上,运用共词分析法,以SPSS软件为工具,探索国外远程教育的研究热点。研究结果表明,2003至2010年间,国外学者在远程教育领域的研究热点主要集中在对远程教育的技术支撑环境、人文资源环境、教学手段、教学系统中的通讯方式、不同教学层次的学习效能、教学模式中的教师作用和研究方法等七个方面的研究。

中长跑运动训练对心脏收缩时间间期的影响

采用MCA-3C心脏功能综合检测仪,观察男子中长跑运动员在功率自行车上进行递增负荷运动时心脏收缩时间间期各指标的变化,并与非运动员进行比较,从而对中长跑运动员的左心功能进行系统评价。结果发现：安静及递增负荷运动过程中中长跑运动员LVET和PEP相对较长;递增负荷运动过程中,中长跑运动员心脏功能表现出优于普通大学生的心脏功能水平。
