The Impact of an Obstacle Course Sport Education Season on Students' Aerobic Fitness Levels

Abstract

The purpose of this study was to determine if factor patterns of selected sports skills were similar for two samples, a skilled sample and one consisting of a wide range of skills. Comparisons were also made with kinesiological evidence regarding the patterning of basic sports skills. Data consisting of performance scores on various sports skills were available for 166 high school girls. Out of this sample, a smaller sample was drawn consisting of 69 girls who were above average in skill. Two factor models, alpha and incomplete image analysis, were used in the analysis of this data. The factor pattern of selected sports skills performed by subjects above average in skill was similar in many respects to that of a sample which included a wide range of skill. The primary difference lay in the clustering of overarm skills which appeared in the above-average factor pattern. The overarm and push patterns of the above-average sample resembled the patterns of skill obtained through kinesiological analysis. The structure of kicking, underarm, and sidearm skills remained obscure, based on the results of factor analytic techniques.     

汉英数词修辞功能对比研究

数词是人类最早认识和使用的词类之一,不少数词在语言的发展过程中获得了十分丰富的语言意义。本文从数词修辞功能的角度出发,通过汉英对比的方法,尝试对汉语和英语中数词的修辞功能进行了初步的探讨。     

Pity and Justice in Rousseau's Emile: Developing a Concern for the Common Good

Scholarly accounts of the training of pity in Jean-Jacques Rousseau's Emile focus on how Emile's tutor activates the psychological mechanisms necessary for the feeling of pity in book 4 of the text. This account is inadequate, for it fails to show how Emile acquires the evaluative ability to make the judgment about who deserves pity as well as the willingness to adjudicate his own and others' interests. In this article, Wing Sze Leung argues that books 1 through 3 lay the foundation by developing in Emile the attitudes and dispositions that guide him in his judgment-making about which kind of life he should pursue. Books 4 and 5 then develop Emile's ability to make interpersonal judgments of pity through habituated practice. By gradually cultivating Emile's sensitivity to the potential conflict between his self-interests and others' well-being, as well as the resolution to refrain from infringing on others' interests and to pursue the common good, Rousseau's long-term educational project molds Emile's disposition to act as justice demands. The article concludes with a brief response to some criticisms about Rousseau's educational project.     

异亮氨酸对大鼠空肠形态和抗菌肽表达的影响

目的:研究不同浓度的异亮氨酸对大鼠空肠形态和抗菌肽表达的影响;方法:选用40只健康断奶SD大鼠,随机分为四组,分别饲喂含有不同浓度异亮氨酸的饲粮(基础日粮+0％、0.5％、1.0％或1.5％异亮氨酸),试验期为14 d.HE染色观察空肠形态变化,通过荧光定量PCR测定空肠中抗菌肽的表达水平.结果:1)对照组大鼠空肠绒毛整齐,黏膜上皮界限清晰,隐窝较浅,0.5％和1.0％异亮氨酸组大鼠空肠绒毛较对照组排列整齐,绒毛较高,隐窝较浅;与0％、0.5％和1.0％异亮氨酸组相比,1.5％异亮氨酸组大鼠绒毛高度较低,隐窝深度增加.2)与对照组相比,0.5％、1.0％和1.5％异亮氨酸均在不同程度上显著提高了空肠防御素rBD -1的表达,其中0.5％异亮氨酸组大鼠空肠防御素rBD -1表达增加了2.3倍,1.0％异亮氨酸组rBD -1表达量增加了13.1倍,1.5％异亮氨酸组rBD -1表达量增加了14.2倍.结论:添加异亮氨酸可显著增加大鼠空肠防御素基因的表达,适量的异亮氨酸对空肠黏膜形态具有改善作用,过量异亮氨酸可能破坏空肠黏膜形态.     

Boys go fishing,girls work at home: gender roles,poverty and unequal school access among semi-nomadic fishing communities in South Western Madagascar

Drawing from data gathered in South Western Madagascar in 2011, the work explores the combination of poverty and traditional gender roles as a critical factor in determining unequal school access among young people from semi-nomadic fishing communities. It demonstrates that from the age of early puberty, most boys go fishing with their fathers and brothers whilst most girls from the same families work at home. In contrast to the school systems observed in many developing society contexts, which demonstrate female marginalisation, in South Western Madagascar both boys and girls are marginalised. Instruments of global policy designs, such as positive discrimination for girls, seem ill-suited to resolve the problem. Instead, the authors call for a more tailored and context-specific approach to address the particular challenges amongst semi-nomadic fishing communities in Madagascar.
