田中原 《沈阳体育学院学报》2003,(2):103-105

运用SPSS软件对悉尼奥运会男子 4 0 0米栏前 8名运动员预赛、半决赛、决赛三个赛次的分段用时进行相关分析和回归建模 ;同时 ,对其栏间步节奏及过第 5栏、第 8栏的名次与最终名次进行相关分析。结果表明 :预赛、半决赛第 1、2段落的分段成绩与赛次成绩呈负相关 ,其余各段落除半决赛中第 5段成绩外 ,均与各赛次成绩呈显著正相关 ;各赛次过第 8栏时的名次与最终名次呈显著相关性 ;根据各赛次体力分配 ,各栏间步数随赛次的延伸有减少的趋势。最终建立的预测模型经方差检验效果高度显著。  相似文献

万颖 《商丘师范学院学报》2005,21(6):129-131

以两院制为主要存在形式的英国议会既是历史发展的必然,也是现实政体的需要.其积极的历史作用应该予以充分肯定.分析英国议会两院制的合理性对于我们这个历史上不曾真正实行过议会政治与议会两院制的民族与国度,有很多有益的启示.  相似文献

论"二分法"的终结与"三分法"的勃兴   总被引：1，自引：0，他引：1

二点论比一点论具有更深刻更果断的特点。但由于它难以在动态中把握持久平衡，无法捕捉两极之间的那个“第三者”，因而不能最终战胜形而上学。能够驾驭两极，游刃于“第三者”的只有三点论，它的最初表现形态是由分到合，即由一分为二到合二而一的，一分为三则是它发展及转化的最高环节。所谓一分为三，就是对多样性世界的三分看法，它反映了事物的全面(正面、反面，侧面)，把握了矛盾的全体(静态矛盾、动态矛盾，矛盾中间)，概括了人类文明的全局(物质文明，政治文明、精神文明)，是科学的世界现与方法论。“三”便是万物的基元。  相似文献   

The Impact of an Erasmus Placement in Students’ Perception of their Intercultural Communicative Competence     

Ramiro Durán Martínez  Gloria Gutiérrez  Fernando Beltrán Llavador  Fernando Martínez Abad 《Journal of Intercultural Communication Research》2016,45(4):338-354

Pre- and post-questionnaires answered by UK Nottingham Trent University (NTU) and Spain’s University of Salamanca (USAL) students on their placement abroad support a comparative analysis of its impact on their intercultural communicative competence, comprising the awareness, attitude, skills and knowledge dimensions. NTU students started their placements with better results in them all. Yet, while both groups completed their stay with a similarly increased awareness, the knowledge and skills of the USAL group matched the results of NTU students and, whereas the scores of the attitude dimension towards the host country of NTU students did not increase significantly, those of USAL students decreased.  相似文献

采用文献资料法和逻辑分析法,对二打一扑克竞技化改革问题进行研究.指出,二打一扑克契合休闲时代的娱乐特征,具有巨大的商业价值,对项目进行改革是适应经济社会和体育发展的需要,也是现存问题“倒逼”的结果;改革以网络为表现形式,其实质是竞技娱乐一体化;改革有利于满足各方利益需求,推动项目发展,但也可能出现过度商业化、娱乐化、工具化等问题.需要做好顶层设计,协调好相关利益主体的关系,整合资源优势,促进我国棋牌运动的转型发展.  相似文献   

Making Sense of the Online Forum Posts of Two Books on Zheng He’s Voyages     

Dexin Tian  Chin-Chung Chao 《Journal of Intercultural Communication Research》2017,46(3):191-209

This paper studies the online forum posts at the websites of Amazon and Goodreads of two books on Zheng He’s voyages. The findings are threefold: First, most of the online forum participants play their due roles and satisfy the six conditions of Dahlberg’s model of an ideal online public sphere. Second, the emerged themes match the six conditions of Dahlberg’s model. The readers’ reviews at the two Western social media websites are mostly positive and rational. Implications of the study are also discussed.  相似文献   

Key somatic variables associated with,and differences between the 4 swimming strokes

ABSTRACT

This study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 “common” characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes).  相似文献
