重言管窥

重言源远流长,应用广泛普遍。它结构独特,灵活多样;它短小凝炼,鲜明生动,往往起到画龙点睛的作用。通过重言来构词或构形,是汉语悠久的历史传统,也是具有鲜明民族特色的语汇、语法现象。在文学创作中,重言运用一直被当作主要的语言表现手法之一。重言的意义不仅表现在语言、文学上,而且渗进更广泛、深刻而根本的中国“社会传统”和“心理习惯”之中。它成为一种文化现象,对中国语言及文学、文化的历史、现实与未来产生重要的影响。     

加强未成年人的思想道德教育势在必行

道德是社会生活中调节人与人之间、个人与社会之间相互关系的行为规范总和,它是一个国家文明的象征,最能反映一个国家国民素质的高低.未成年人是祖国的未来,青少年强则国家强,青少年兴则民族兴.而当今的未成年人在现实生活中所表现出来的道德行为不能令人满意,必须加强对青少年的思想道德教育,使祖国的未来健康成长,从而成为社会有用的人才.     

图书馆文献订购经费向开放出版经费转化:目标、挑战与策略

中国现代思想史上的"陶胡分歧"

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。     

潮州产10种野菜中硝酸盐、亚硝酸盐及Vc的含量

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．     

影响中国农业科技成果推广的因素分析

从供给和需求的角度分析了我国农业科技成果推广水平低的原因,通过供求均衡分析,认为农业科技成果推广率的提高必须在刺激农业科技成果有效需求的同时,增加农业科技成果供给,并提出增加农业科技成果的供给和需求的措施建议。     

战国秦汉时期的里社与私社

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。     

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

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.     

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

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.
