在军校引入TMF训练方法可行性的研究     

杨祥红  王正磊  陈宏昱  窦文博 《当代体育科技》2020,(1):33-34

抗阻力训练是军校体能训练常用的训练方法,而训练至肌肉失败(TMF)作为抗阻力训练中一种新兴的训练方法,已经在健身领域引起越来越广泛的关注,并已经逐步应用于专业运动员训练中。TMF在军校这类对体能要求较高的机构内具有广阔的应用前景,但现阶段TMF在军校还未得到推广,大部分军校仍然沿用过去的传统抗阻力训练模式。本文从介绍抗阻力训练与TMF的相关概念出发,分析了TMF的作用机制,提出了在军校训练中引入TMF的可行训练项目。为了进一步研究TMF对于军校学员体能训练效果的影响,本文选取成绩相近的部分学员进行分组对照实验,运用统计学方法处理实验结果,从而证明了TMF对于学员体能具有明显提升作用,最后对本次研究工作进行了总结和展望。  相似文献   

集装化危险品物流作业风险因素识别与评价     

何景师  张智勇 《上海海事大学学报》2020,41(4):62-69

为识别与评价集装化危险品物流作业的风险因素，通过鱼骨图分析法构建风险因素评价指标体系。以风险发生的概率和后果为决策变量建立基于熵权 层次分析法（analytic hierarchy process, AHP）约束的数据包络分析(data envelopment analysis, DEA)法的风险评价模型。利用熵权 AHP解决传统DEA法的权重无限性问题，利用DEA法求解风险极大、极小值并对风险因素进行评价与排序。研究发现，人员风险、包装风险达到风险极大值，集装箱风险达到风险极小值。研究得到各风险因素决策单元的风险降低比例，并根据风险因素的特点提出集装化危险品物流作业风险管理的建议。结果表明了该评价模型的适用性和评价方法的科学性。  相似文献

基于ICWGT和灰色关联分析法的起重机安全评价     

肖汉斌  熊楚宸  祝锋  刘敏 《上海海事大学学报》2020,41(2):117-122

针对目前起重机安全评价过于依赖主观权重且忽视起重机安全状态变化趋势的问题，建立基于改进博弈论组合赋权法（improved combination weighting method of game theory，ICWGT）和灰色关联分析法的起重机安全评价体系。在该评价体系中，收集样本数据以确定评价值，构建评价等级空间来计算起重机行为特征序列与标准行为特征序列的关联系数。运用ICWGT在层次分析法和信息熵 未确知测度理论确定的主、客观权重中寻找平衡。充分考虑专家经验和样本数据，确定优化权重以改善关联系数的分配问题，从而获取起重机灰色关联度评价值和安全等级，旨在对起重机安全状态变化趋势进行更加准确的定量描述和定性分析。实例分析验证了该评价体系的有效性。  相似文献   

Using an interactive platform to recognize the intersection of social and spatial inequalities     

Lisa Poling  Travis Weiland 《Teaching Statistics》2020,42(3):108-116

With the creation of interactive tasks that allow students to explore spatial ways of knowing in conjunction with their other ways of knowing the world, we create a space where students can make sense of information as they organize these new ideas into their already existing schema. Through the use of a Common Online Data Analysis Platform (CODAP) and data from Public Use Microdata Areas (PUMA), students can explore the communities in which they live and work, critically examining opportunities and challenges within a defined space.  相似文献

Perspectives on peer-review: eight years of Aropä     

Helen Purchase  John Hamer 《Assessment & Evaluation in Higher Education》2018,43(3):473-487

Drawing on eight years of observation and correspondence from the Aropä project, we report on the issues important to academics who conduct on-line student peer-review activities, and the features they request to support their own instructional designs. The Aropä project is unusually broad, having so far supported over 100 instructors at 20 institutions across nine countries, almost one thousand activities, and more than 36,000 individual students. As the designers, developers, maintainers and advisors of an evolving and widely used tool, we use our unique position to report on the perspectives and priorities of instructors and students in this important and developing field.  相似文献

The determinants of the intention to continue voluntary football refereeing     

《Sport Management Review》2020,23(2):242-255

Competitive sports require a regulating body of referees to enforce the rules for the effective operation of the game. However, the number of referees is generally decreasing, leading to organisational problems at the amateur level. The purpose of this research is to identify the factors that determine the intention to continue voluntary refereeing in the context of football in Germany. Combining several concepts as predictors, including both the antecedents and the experience of volunteering, in this study, the authors extend the understanding about volunteers’ intentions to continue their activity and address the research gap regarding the analyses of specific volunteer groups such as referees. By means of an online questionnaire, the authors surveyed voluntary football referees in Germany (n = 4541). Regression analysis reveals the motive of self-orientation, respect shown by athletes, coaches, and spectators towards referees, compatibility of refereeing with one’s occupational and private life, perceived organisational support, and referees’ satisfaction to predict referees’ positive intention to continue with their activity. Simultaneously, experiences of offences during refereeing negatively influence this intention, and younger referees show higher intentions to continue their activity than do older referees. Because volunteer recruitment and retention are expensive, the findings of this study facilitate the improvement of effective retention strategies for the federations responsible for referees.  相似文献
