潘景玲  蔡赓  殷荣宾  孙雷  王国祥 《体育科研》2019,(1):90-95

目的：探讨动态视力在不同类型体育项目间的发展特征，为体育锻炼改善视力的应用研究提供依据。方法：选取6~10岁无专门体育训练经历的在校学生和参加足球、乒乓球、跆拳道、空手道、游泳、体操等项目的俱乐部或体校学生，共603名。使用动态视力检测仪和标准对数视力灯箱测量动态视力和静态视力。计算动静比（动态视力/静态视力），并将其作为衡量动态视力发展水平的指标。结果：6~7岁是动态视力发展的敏感期（P＜0.05），8岁、10岁男性儿童的动静比高于女性儿童，且差异有统计学意义（P＜0.05）。校外体育练习组的动静比高于普通在校学生组（P＜0.05），开放性运动项目的动静比高于闭锁性运动项目（P＜0.05）。结论：参加体育锻炼对动态视力的发展有积极的影响，且不同运动项目的影响效果不同。  相似文献   

Efficacy of using non-linear pedagogy to support attacking players’ individual learning objectives in elite-youth football: A randomised cross-over trial     

Simon J. Roberts  James R. Rudd  Matthew J. Reeves 《Journal of sports sciences》2020,38(11-12):1454-1464

ABSTRACT

The present study examined the efficacy of a coaching curriculum, based on non-linear pedagogy, on improving attacking players’ individual learning objectives (ILOs) in elite-youth football. Participants included 22 attacking players (i.e., centre-forwards, wide-players and attacking midfield players) from a professional football academy in England. The players were randomly appointed to both control (CON) and intervention (INT) periods following baseline measures. The INT (non-linear) and CON (linear) periods were both designed to support the ILOs provided to each player as part of the elite player performance plan. The study adopted a randomised cross-over design and ILOs considered important for attacking players (i.e., strong foot finishing, weak foot finishing, 1-v-1 and decision-making) were evaluated using the Loughborough Shooting Skill Test. The results showed significant differences for INT in 1-v-1 (P< 0.02) and decision-making (P< 0.01). However, there were no significant differences for strong foot finishing, weak foot finishing or time taken. These results support non-linear pedagogy in developing 1-v-1 game play and decision-making but not for technical shooting proficiency.  相似文献   

体育产业高质量发展系统动力机制模型建构与现实考察     

薛昭铭  刘东升  马德浩 《沈阳体育学院学报》2020,(2):116-124

通过文献资料法和案例分析法,以系统论为视角对体育产业高质量发展进行动力机制模型建构,并以江苏体育产业发展经验作为现实考察。研究认为:体育产业高质量发展作为政策性议题,其实践取向应围绕产业的商业性效益逻辑和体育的人文性功能价值进行有机融合,进而推动体育产业在社会主要矛盾、资源配置方式、产业结构模式、经济增长状态4个维度中积极寻求转向。推进体育产业转向高质量发展是一个系统问题,系统运转的关键在于形成运动项目内涵丰富的内生机制、社会进步和经济发展环境的外发机制以及业态载体和空间载体充沛的内外联动机制。当前运动项目产业化内在张力不足、外部环境要素缺位、空间载体培育良莠不齐是现实挑战。提出注重深度内涵式发展、强化务实载体建设、营造适宜外部环境3个由意识理念引领到具体工作抓手的发展思路。  相似文献   

动态可持续能力与企业可持续绩效的关系研究          下载免费PDF全文

商华  陈任飞 《科研管理》2018,39(10):79-89

企业的动态能力和可持续发展已是学术探讨的一个重要命题。可持续发展作为一种管理趋势，在现代组织战略管理中发挥着日益重要的作用。但现有文献对于如何将可持续发展更加动态化同时与企业战略相结合转化为企业绩效及其过程研究较为匮乏。本研究基于资源管理视角，通过收集163个企业管理人员调研数据并使用最小二乘结构方程模型进行建模（PLS-SEM）分析了动态可持续能力对企业可持续绩效的全面影响及其内在机制。研究结果显示：动态可持续能力由监控、捕获和重构能力构成，动态可持续能力对企业可持续绩效各维度具有显著正向影响，资源管理能力部分中介动态可持续能力与企业环境和社会绩效的关系，但对经济绩效没有中介效应。本研究丰富了动态能力和可持续发展理论，并为企业在面对可持续发展问题时提供有效的经营管理建议。  相似文献   

An example of the use of dynamic mathematics software to create problem-solving environments that serve multiple purposes     

Erdem Çekmez  Buket Özüm Bülbül 《Interactive Learning Environments》2018,26(5):654-663

Problem-solving is regarded as a major component of mathematical performance, and well-designed problem-solving-based learning environments have the potential to assist students in developing a meaningful understanding of mathematical concepts and procedures. In this respect, given its various features, dynamic mathematics software has been regarded by mathematics educators as a promising tool for designing such environments. This study presents an example of the use of technology to create a dynamic learning environment through a discussion of the pedagogical value of a problem selected for an activity, followed by the implementation sequence of the problem-solving activity in the classroom. The students’ experiences during the implementation of the activity are also discussed; and finally, an additional version of the problem is recommended for use in the classroom.  相似文献   

Teacher Perceptions of Moodle and Throughput in a Blended Learning Programme for In-Service Secondary School Mathematics Teachers     

Mdutshekelwa C. Ndlovu  Ingrid Mostert 《Africa Education Review》2018,15(2):131-151

The purpose of this article is to analyse teachers’ perceptions of using the modular object-oriented dynamic learning environment (Moodle) platform as a learning management system in a small-scale blended learning (b-learning) Advanced Certificate in Education (ACE) programme for in-service secondary school mathematics teachers in South Africa. It describes how the Moodle platform was used in combination with on-campus and later off-campus contact sessions for a widely dispersed population of 76 in-service mathematics teachers over a four-year period. Qualitative data was gathered by means of a questionnaire with open-ended items, while quantitative data was gathered from the centre's archives. The main findings were that Moodle enabled in-service teachers to experience social, cognitive and teaching presences, through synchronous and asynchronous discussions with peers and facilitators, and a teaching presence by submitting their inquiries and assignments online for facilitators to provide them with answers and feedback. The main obstacles to the integration of Moodle were limited availability of technology, slow speed, and unaffordable cost when available. With increased broadband connectivity Moodle holds the prospect for diversifying b-learning experiences that can support teachers’ professional learning outcomes and throughput for distributed populations of practising mathematics teachers, in particular.  相似文献   

基于动态分阶势场法的船舶自动避碰系统     

罗贤程  尹建川  李宏宾 《上海海事大学学报》2020,41(1):1-7

为使船舶在多船避让环境下适应航行环境的变化并自动复航,提出基于动态分阶势场法的船舶自动避碰系统。该系统基于动态势场避障规划算法,利用模糊综合评价法量化船舶碰撞危险度;依据《国际海上避碰规则》确定本船在不同会遇局面下的避让行动,并据此对斥力势函数进行调整。该系统将本船的避碰过程划分为航迹保持、避让和复航3个阶段,根据不同阶段的要求构建动态分阶势场;利用动态分阶势场法对船舶的航行环境进行建模,进而生成恰当的航向指令;利用自动舵产生舵角指令控制船舶完成避让、复航和航迹保持。仿真结果表明:该自动避碰系统可以引导船舶完成既定的避让行动,并能使船舶在安全会遇距离上驶过;该系统可以适应航行环境的变化,且具备航迹保持能力。  相似文献   

动态接力点模式下双自动化轨道吊协调调度     

邱亚  梁承姬  张悦 《上海海事大学学报》2020,41(3):53-59

为提高自动化集装箱码头堆场中自动化轨道吊(automated stacking crane,ASC)的作业效率,研究箱区动态接力点对双ASC作业效率的影响。考虑双ASC作业过程中的安全距离、相互冲突等因素,建立以最小化双ASC最长完工时间为目标的混合整数规划模型,利用遗传算法对该模型进行求解。与固定贝位接力模式进行对比,结果表明,相较于固定贝位接力模式,动态接力点模式下双ASC的作业效率更高。在不同规模算例背景下,将遗传算法与CPLEX的计算结果进行对比,验证了遗传算法的有效性。  相似文献

吴卫  陈雷霆 《科技管理研究》2018,(11)

以创新驱动发展为研究视角,界定承载研发创新功能的新型研发机构的内涵和形成动因,研究不同信息条件下新型研发机构的作用机理。通过建立数理分析模型发现,在完全信息条件下,通过组织间合作建立新型研发机构,各参与方能够获得经济收益和非经济收益,即使在没有经济收益的极端情况下,参与方也可以获得非经济收益,如学习能力、创新能力、管理能力的提升。在不完全信息条件下,创新研发风险越高,通过各方合作建立新型研发机构,获得的研发创新收益越大。并提出相关建议,以提高新型研发机构的创新能力。  相似文献
