行动、断言、事件和主体——动态道义逻辑的几个基本概念     

周祯祥  胡群香 《河池学院学报》2006,26(6):13-22

1988年梅耶给出一个动态道义逻辑(DDL)系统,该系统不是处理一般的词项和命题,而是把行动和断言作为逻辑的处理对象。梅耶之后,这一系统不断完善,使得对于道义逻辑的讨论扩展到实施行动的主体,即行动者以及和行动者相关的事件。在此对DDL及其个体事件扩展进行粗略讨论,意在表明道义逻辑的探索,是一个不断地从抽象的一般道义范畴朝向具体的生活世界范畴的过程。  相似文献   

Validity and reliability of a linear positional transducer across commonly practised resistance training exercises     

Harry F. Dorrell  Joseph M. Moore  Mark F. Smith  Thomas I. Gee 《Journal of sports sciences》2019,37(1):67-73

This study investigated the validity and reliability of the GymAware PowerTool (GPT). Thirteen resistance trained participants completed three visits, consisting of three repetitions of free-weight back squat, bench press, deadlift (80% one repetition maximum), and countermovement jump. Bar displacement, peak and mean velocity, peak and mean force, and jump height were calculated using the GPT, a three-dimensional motion capture system (Motion Analysis Corporation; 150 Hz), and a force plate (Kistler; 1500 Hz). Least products regression were used to compare agreeability between devices. A within-trial one-way ANOVA, typical error (TE; %), and smallest worthwhile change (SWC) were used to assess reliability. Regression analysis resulted in R² values of >0.85 for all variables excluding deadlift mean velocity (R² = 0.54–0.69). Significant differences were observed between visits 3-2 for bench press bar displacement (0.395 ± 0.055 m; 0.383 ± 0.053 m), and deadlift bar displacement (0.557 ± 0.034 m; 0.568 ± 0.034 m). No other significant differences were found. Low to moderate TE (0.6–8.8%) were found for all variables, with SWC ranging 1.7–7.4%. The data provides evidence that the GPT can be used to measure kinetic and kinematic outputs, however, care should be taken when monitoring deadlift performance.  相似文献   

HAPA理论背景下大学生锻炼行为与锻炼效果的干预研究          下载免费PDF全文

王银晖 《河北体育学院学报》2016,30(4):53-60

以健康行动过程取向理论为理论背景,对644名在校大学生进行教育干预实验研究.干预措施包括课堂和课下指导、微信等即时通信工具宣传、发放健康行为宣传册等,干预时间为10周.在干预前后共进行了两次问卷调查、三次身体素质测试.结果:①根据HAPA阶段划分,大学生大部分处于健康锻炼行为无意向和意向阶段,仅有14.1％处于行动阶段;②干预对大学生锻炼行为意向水平和体育锻炼等级具有积极影响;③干预对大学生身体素质整体水平有积极影响;④锻炼自我效能作为社会认知变量在健康行为过程取向理论的各个阶段都发挥重要作用.建议通过提高个体锻炼自我效能感和制订合适的锻炼计划增加大学生中参加有规律的体育锻炼人数比例.  相似文献   

Towards an operationalized and effective school self-evaluation system: An ongoing action research study in Chinese secondary schools since 2011     

《Studies in Educational Evaluation》2019

School self-evaluation (SSE) is an effective mechanism that helps schools to put in place strategies to improve an aspect of school quality. By implementing an action research study of SSE in 24 Chinese secondary schools across seven cities since 2011, the present study generalizes and proposes an operationalized and effective SSE system to illustrate how to operationalize SSE effectively. The system was developed in three essential parts: (a) constructing the measurement model of SSE, which included identifying the framework and indicators to determine the primary evaluation contents, and designing operational evaluation modules to apply SSE indicators to school practices and integrate them into routine school operations; (b) establishing a cooperation mechanism between internal SSE groups and external “facilitative friends” to conduct SSE with different roles allocated; and (c) summarizing detailed implementation procedures and key strategies to implement a cyclical, regular and sustainable SSE process step by step.  相似文献   

核心力量训练对高中生功能性运动能力影响的研究--以普定县第一中学为例     

李明 《当代体育科技》2020,(12):48-50

本文采用文献资料法、实验法等,探究核心力量训练对高中生功能性运动能力的影响。通过对对照组和实验组进行为期3个月的实验,实验组通过核心力量训练的介入,7个测试动作中,跨栏架步、直线弓箭步、稳定俯卧撑和旋转稳定性等动作模式质量得到显著提升,其他提升不显著,就整体而言,实验组学生的功能性运动能力得到提高;对照组学生的7个测试动作虽有提升,但提升不明显,就整体而言,对照组学生的功能性运动能力提高不明显。  相似文献   

A double win: practice and participation in an action learning facilitators’ set     

Nicola Wilson 《Action Learning: Research and Practice》2019,16(2):178-186

This account of practice shares insights from past and present members of a self-facilitating action learning set, where each of the members is an action learning facilitator. Motivations for joining the set encompassed the opportunity to ‘practice what you preach’ by being a set member as well as a facilitator, the potential to refine and develop facilitation practices in a safe environment and space for personal development.  相似文献   

对消费者不苛求对欺诈者不放任--对《消法》第49条的认识和理解     

揭新华 《临沂师范学院学报》2002,24(1):32-36

整顿市场经济秩序的重点是保护消费者的经济利益。《消法》中所规定的“消费者”,应当包括为“打假”而购买商品的人,因为“打假”有利于保护全体消费者的利益,有利于监管市场,符合《消法》的立法本意。对欺诈行为的确认,不能给经营者提供“无意售假”的借口,应当依据已经发生的客观事实,从各个方面去认定经营者的欺诈行为。对“增加赔偿”的规定,应当作整体和全面的理解：当消费者的受害损失超过购买商品和提供服务价款的一倍时,应当按实际损失甚至更高的标准进行赔偿;当经营者许诺“假一罚十”时,法律应当支持受害消费者获得10倍的赔偿;法律还应当从更深入的层次采取措施,使商品销售者和提供服务者的欺诈经济成本高于欺诈经济所得,力争在源头上杜绝对消费者实施欺诈行为的心理动机。  相似文献
