The effects of ACL injury on quadriceps and hamstring torque,work and power

The aim of this study was to assess isokinetic torque, work and power between non-injured, ACL (anterior cruciate ligament)-deficient and ACL-reconstructed individuals. Ten healthy, non-injured individuals, seven unilateral ACL-deficient individuals and six unilateral ACL-reconstructed individuals were assessed for isokinetic quadriceps and hamstring strength at 1.05 and 3.14 rad ·s -1 . Peak torque, total work, average power and the ratio of peak torque to body mass were computed for both velocities. Peak torque was also corrected for body mass, using allometric modelling. The non-injured individuals showed significantly greater quadriceps peak torque to body mass ratios than the ACL-deficient and ACL-reconstructed individuals at both velocities, and greater hamstring peak torque to body mass ratios than the ACL-deficient group at 3.14 rad · s -1 ( P ? 0.05). The ACL-deficient individuals displayed greater quadriceps and hamstring peak torque, total work and average power than the non-injured individuals at 1.05 rad · s -1 ( P ? 0.05). The ACL-deficient individuals also displayed significantly greater peak torque, total work and average power than the ACL-reconstructed individuals for the quadriceps at both velocities ( P ? 0.05). The ACL-deficient individuals demonstrated greater hamstring peak torque and total work than the non-injured individuals at both velocities ( P ? 0.05). The allometrically modelled peak torques at both isokinetic velocities demonstrated that the quadriceps muscle values were significantly higher in the non-involved than the involved limb. The hamstring peak torques corrected for body mass were significantly higher in the non-involved than the involved limb only at 1.05 rad ·s -1 . The main finding from the present study is that isokinetic measures in ratio-scaled or absolute units yield a different outcome and, hence, interpretation compared with the allometric approach.     

An analysis of mobility in global rankings: making institutional strategic plans and positioning for building world-class universities

Since the start of the twenty-first century, university rankings have become internationalized. Global rankings have a variety of uses, levels of popularity and rationales and they are here to stay. An examination of the results of the current global ranking reveals that well-reputed world-class universities are amongst the top ranked ones. A major concern for university administrators in many parts of the world is how to use the global rankings wisely in their mid-term and long-term strategic planning for building their institutions into world-class universities. Four major global rankings have been developed: the Academic Ranking of World Universities, the World University Rankings, the Webometrics Ranking of World Universities and the Performance Ranking of Scientific Papers for World Universities. The main purpose of this paper is to explore the most influential indicators in these global university rankings that will affect the rank mobility of an institution. Based on an analysis of correlation coefficients and K-means clustering, a model of strategic institutional planning for building a world-class university is proposed.     

民办高校公共关系的探讨研究——以紫琅职业技术学院为例

近几年,高考生源紧缩,公办扩招,民办高校已面临着非常严峻的发展压力。民办高校犹如夹缝中生存。因此民办高校应充分重视公共关系,提升学校的品牌效应,才能实现科学、稳定、可持续发展。本文以紫琅职业技术学院为例,探讨学校如何树立服务型高校的办学理念,总结提炼自身的办学特色,重视公共关系管理,提升品牌形象。     

基于流程再造和组织设计的高校教务管理探究

高校的教务管理是高校教学的重要管理方面,对维护教学秩序和促进教学改革具有重要的作用。笔者主要根据流程再造和组织设计模式探讨了教务管理中存在问题和解决方式,以期能够为相关的实践提供些许理论依据。     

试论“气韵生动”

"六法"的提出,为我国造型艺术领域的创作和评论开创了一个精密而具有普遍艺术规律的理论体系。而"气韵生动"是"六法"中的第一法,它比较抽象又放在第一位,既是绘画创作的首要目的又是对作品评价的标准。但对"气韵生动"含义的具体解释以及产生气韵的根源,则一向是众说纷纭。我认为对这一重要理论进行探讨,对于阐明中国古代画论的真实含义,继承中国文艺理论的优秀传统,以及对当前的绘画创作,都将有积极的意义。     

校企联合培养工科学生的研究与实践

学校与企业联合培养工科学生,是普通高校实行工程教育的一个有效途径。学校和企业联合培养工科学生,需要专业或专业群与合作企业协同对可用教学资源进行集成和配置。围绕测控技术与仪器专业学生的培养,分析了与企业开展深度合作的可行性、制度设计和实施路径。在试点工作中,把实践教学部署在企业现场,并结合CDIO大纲和企业培训大纲以指导实践教学,使得实践教学环节尽可能映射工程实践。     

生态社会主义思潮对我国当前社会改革的启示

生态社会主义产生于20世纪70年代西方的绿色运动,源于西方生态运动和社会主义思潮,是一种以建立维护自然生态平衡为基础,满足新型社会需要为目标,倡导人与自然和谐发展的未来社会理论。自20世纪90年代以来,它在生态问题、经济理论、政治理论基础、文化价值取向等方面取得显著发展,并形成了一整套独特的理论体系。该理论为我国当前正在进行的政治、经济、文化、社会等领域的改革提供了重要的启示,有助于我国当前正在进行的社会改革取得更好的效果。     

腾冲猴桥傈僳族尼扒情况调研

尼扒是生活在傈僳族地区的一个特殊群体,由一些年纪较大的男性组成,他们平时用自己的巫术为人驱鬼治病,消灾解难,参与丧事办理,节日期间“上刀杆”、“下火海”,祈福纳祥.在长期田野调查及其结合相关国内外研究成果的基础上,描述了腾冲猴桥傈僳族尼扒的基本情况,包括他们的文化、社会功能、现状,及其人们对尼扒和巫术的看法、态度等.     

萨满文化对蒙古族造型艺术的影响

萨满教是我国古代北方游牧民族普遍信仰的一种原始宗教。蒙古族及其先民长期笃信萨满教,这种信仰渗透到日常生活的不同层面和社会文化的各个领域,蒙古族造型艺术早期审美意识的形成就和萨满信仰与萨满文化活动分不开。蒙古族造型艺术的内容很多,本文仅以岩画艺术、建筑艺术、服饰艺术以及色彩取向为例,以点带面来分析萨满文化对蒙古族造型艺术的巨大影响。     

新建本科院校以考试制度改革为抓手提高育人质量

考试是教学工作的重要环节,是评价和改进教学,培养学生创新能力的基重要途径。科学规范的考试能对教学起到促进作用,有利于教师教学能力的提高,激发学生学习的积极性。随着教育教学改革的不断深入,新建本科院校其传统的考试管理模式不能满足人才培养的需要,本文现就考试育人等方面存在的问题提出一些意见和建议。
