中国现代思想史上的"陶胡分歧"     

吴翔 《南京晓庄学院学报》2006,22(5):9-16,56

陶行知与胡适的分歧贯穿了五四之后的近三十年中国现代思想史上的大事。二人之间的最初教育分歧不在教育观点本身,而是“教育界分歧”,始于1926年“庚款风波”;其次是30年代的政治9牾,基于两种基本爱国观的难于兼容,但非以政见分歧为主要内容;其三,双方主要的、根本的分歧是30年代形成的关于基本价值观——五四价值观的分歧。陶推崇一二九“大众”运动,反思并批判五四“小众”运动;由此出发,陶形成了自己的大众教育观,及总的大众价值体系,全面否定了新文化运动及胡在其中的历史地位。  相似文献   

潮州产10种野菜中硝酸盐、亚硝酸盐及Vc的含量     

邱贺媛  曾宪锋 《韩山师范学院学报》2005,26(6):65-68

利用分光光度法测定了潮州产10种野菜中硝酸盐、亚硝酸盐的含量，利用氧化还原滴定法测定了维生素ca含量．结果表明：月光花、决明、铁苋菜和叶下珠的硝酸盐含量低于轻度污染水平（432mg／kg鲜重），亚硝酸盐含量低于无公害蔬菜亚硝酸盐含量的限量标准（44．0mg／kg鲜重），它们属于一级野菜，可以安全食用；鸡矢藤、白勒和苎麻的硝酸盐含量低于785mg／kg，属于中度污染水平，亚硝酸盐含量低于无公害蔬菜亚硝酸盐含量的限量标准，属二级蔬菜范围，不宜生食，煮熟或盐渍可安全食用；鳢肠硝酸盐含量高于785mg／蚝而低于1440mg／kg，亚硝酸盐含量低于无公害蔬菜亚硝酸盐含量的限量标准，维生素C含量高于50mg／100g鲜重，属于三级蔬菜，不可生食和盐渍，可熟食。牡荆和肖梵天花虽然硝酸盐含量很低，但维生素C含量较低，亚硝酸盐含量高于无公害蔬菜亚硝酸盐含量的限量标准，所以不宜食用．  相似文献   

Shear capacity of reinforced concrete columns strengthened with CFRP sheet     

谢剑  刘雪梅赵彤 《浙江大学学报(A卷英文版)》2005,6(8):853-858

INTRODUCTION There is increased need in recent years for strengthening or rehabilitation of existing reinforced concrete structures adversely affected by overloading, construction material deterioration, seismic loads, structural deformation, etc. An effective method for increasing the shear capacity of reinforced concrete columns is the use of externally bonded carbon fiber reinforced plastic (CFRP) systems (ACI, 2002). FRP systems were first applied to reinforced concrete col-umns i…  相似文献

战国秦汉时期的里社与私社   总被引：3，自引：0，他引：3  

杨华 《天津师范大学学报(社会科学版)》2006,(1):21-28

近年来长江流域出土的简牍材料表明,战国秦汉时期南方楚地存在着很多里。里皆有其社,社主又有“地主”、“侯土”等异名。围绕着里社的巫术活动十分盛行。从战国至汉代,里、社合一之制基本得到沿续,然而里、社分离的历史趋势已明显存在。西汉晚期,民间百姓在里社(官社)之外另立私社。东汉初年的《序宁祷券》证明了此种私社的存在,西汉中期邗江汉墓的《神灵名位牍》和秦朝末年的周家台秦简《日书》中关于私社的内容,比文献中唯一一条材料(见《汉书.五行志》)要分别提前36年和177年。  相似文献   

Individual and contextual factors in ethical decision making: A case study of the most significant doping scandal in Canadian university sports history     

《Sport Management Review》2016,19(1):61-68

This case study is written for instructors of sport management courses focused on ethics and integrity-related issues in team environments. The case highlights the real world example of the University of Waterloo Warriors varsity football that, in 2010, experienced the most significant doping scandal in Canadian university sports history, with a total of nine anti-doping rule violations asserted through the Canadian Centre for Ethics in Sport. This case study also incorporates the findings of an independent review of the Waterloo football program in relation to the use of banned substances, and includes first-hand accounts from Bob Copeland who was the acting director of athletics. These findings are then interpreted in the context of relevant theory related to performance enhancing drugs (PEDs) use. Along with the findings of this review, which included interviews with athletes, coaches, and administrators, the case study provides important insights into ethical decision making processes and leadership structures in a team sport environment. Particular emphasis is placed on the role that individual cognitive antecedents and contextual organizational factors (i.e., policies, leadership, ethical climate, and infrastructure) play in ethical decision-making processes.  相似文献   

Coordination pattern of baseball pitching among young pitchers of various ages and velocity levels     

Hsiu-Hui Chen  Chiang Liu  Wen-Wen Yang 《Journal of sports sciences》2016,34(17):1682-1690

This study compared the whole-body movement coordination of pitching among 72 baseball players of various ages and velocity levels. Participants were classified as senior, junior, and little according to their age, with each group comprising 24 players. The velocity levels of the high-velocity (the top eight) and low-velocity (the lowest eight) groups were classified according to their pitching velocity. During pitching, the coordinates of 15 markers attached to the major joints of the whole-body movement system were collected for analysis. Sixteen kinematic parameters were calculated to compare the groups and velocity levels. Principal component analysis (PCA) was conducted to quantify the coordination pattern of pitching movement. The results were as follows: (1) five position and two velocity parameters significantly differed among the age groups, and two position and one velocity parameters significantly differed between the high- and low-velocity groups. (2) The coordination patterns of pitching movement could be described using three components, of which the eigenvalues and contents varied according to age and velocity level. In conclusion, the senior and junior players showed greater elbow angular velocity, whereas the little players exhibited a wider shoulder angle only at the beginning of pitching. The players with high velocity exhibited higher trunk and shoulder rotation velocity. The variations among groups found using PCA and kinematics parameter analyses were consistent.  相似文献   

功能动作测试在中学生基本运动能力评价中的应用          下载免费PDF全文

徐欣  卢洋  高亚强  仲昭金  姚卫  魏安奎 《体育科研》2016,(1):74-77

目的：采用功能性动作测试系统（Functional Movement Screen,FMS）评价青少年在完成不同功能动作模式时身体各部分的稳定性、对称性和灵活性,研究其基本运动能力及影响因素。方法：以上海市某中学中随机挑选的100名初中生为研究对象,对他们进行7个特定动作的测试并评分,并对测试结果进行统计分析。结果：FMS测试总分满分为21,受试对象FMS总分均分为14.89,总体水平偏低;女生肩关节灵活性和直腿抬高测试得分显著高于男生,但总分上男女生无显著差异;青少年在完成动作时普遍存在身体晃动、力量不足和两侧肌力不对称现象,髋、膝、踝关节灵活性受限且稳定性较差,脊柱的屈伸能力不足,两侧盂肱关节和髋关节的活动能力不对称。在旋转稳定性、跨栏架和直线弓箭步３个测试中这些不足尤为明显。结论：青少年基本运动能力水平较低,大多数人需要进行矫正训练;男女生总体上的表现差异不显著,但女生在肩部灵活性和直腿抬高测试的表现要优于男生,故男生需加强肩部和髋部关节的灵活性锻炼。  相似文献

Structural dynamic responses analysis applying differential quadrature method     

PU Jun-ping ZHENG Jian-jun 《浙江大学学报(A卷英文版)》2006,7(11):1831-1838

INTRODUCTION The differential quadrature method (DQM) was proposed by Bellman and Casti as an analogous ex- tension of the quadrature method for integrals (Bellman and Casti, 1971; Bellman et al., 1972). It can be essentially expressed as the values of the de- rivatives at each grid point as weighted linear sums approximately of the function values at all grid points within the domain under consideration. As a distinct numerical solution technique to obtain the initial and/or boundary …  相似文献
