王成龙 《河北体育学院学报》2019,33(6):41-48

收集2013—2017年我国31个省份体育彩票销售额的面板数据和2017年各省份社会发展指标的相关数据，运用探索性空间数据分析方法（ESDA），对31个省份体育彩票销售额的空间异质性特征及影响因素进行研究。全局空间自相关分析结果表明，体育彩票销售额具有明显的空间聚集性，且呈显著的空间正相关性。经分析，发现31个省份体育彩票销售额不均衡，东部沿海省份的销售额高于西部省份，提出应重点关注西部地区的体育彩票事业发展。31个省份体育彩票销售呈现出以次冷区域为主，个别热点区域和次热区域相结合的特点，说明我国体育彩票销售的区域性寡占市场特征较明显，提出应加强省份间的沟通交流，促进各区域联动均衡发展。在影响因素方面，人均GDP、体育场地面积对体育彩票销售额具有显著性影响，其中人均GDP对南方的影响大于北方，体育场地面积对东北地区的影响大于西南地区，提出应进一步加大对体育场地建设的投入力度，以促进我国体育彩票事业的发展。  相似文献   

Systems model and individual simulations of training strategies in elite short-track speed skaters     

Thibaut Méline  Ludovic Mathieu  Fabio Borrani  Robin Candau 《Journal of sports sciences》2019,37(3):347-355

This study aimed to evaluate the effect of simulated training strategies on performance potential in elite short-track speed skaters. Training load and field-based criterion performances from fifteen athletes (10 males, 5 females) were collected over a 3-month training period and the relationship between training loads and performance was computed with a variable dose-response model using a genetic algorithm. Individual simulations of tapers preceded or not preceded by an overload training (OT) were assessed. We obtained a significant correlation between actual and modelled performances (R² = 0.76 ± 0.07). Regarding model parameters, no significant difference was found between males and females but the time to recover performance tended to be lower in females. Simulations in which the taper parameters were free highlighted that an exponential or a step taper were the most effective for increasing performance compared to a linear taper (p < 0.05). Optimal exponential taper duration after OT was 10.7 ± 2.4d and the optimal load reduction was 75.9 ± 3.7%. OT intensity had the greatest influence on the predicted performance, followed by OT duration, taper decay, and to a lesser extent load reduction during taper and taper duration. Thus, a variable dose-response systems model allows the evaluation of different taper strategies and their potential effect on performance changes.  相似文献   

学生体质健康测试第三方机构督查的独立性     

翟继勇  董琴娟 《武汉体育学院学报》2019,53(2):96-101

运用文献资料法、专家访谈法等研究方法，对我国各省份学生体质健康测试第三方机构督查的独立性进行研究。通过对我国各省份学生体质健康测试第三方机构督查独立性的现状、问题、原因及对策的探索，在政策上，可以为教育行政部门改革提供决策思路和参考，在实践上，可以提高学生体质健康测试督查的权威性和有效性，倒逼学生体质健康测试的规范化实施。研究发现，当前我国各省份学生体质健康测试第三方机构督查的独立性差，主要体现在第三方机构与教育厅存在行政隶属关系、存在利益关联、第三方机构工作自主性差3个方面。影响学生体质健康测试第三方机构督查独立性的因素主要为中国传统文化对体育和公民意识的漠视、当事方的利益诉求对第三方机构督查独立性的限制、法规制度缺位、第三方机构发育程度低等。提出保障学生体质健康测试第三方机构督查独立性的对策：教育部对第三方机构督查的责权划分做出设计安排，培养公民意识，扩宽经费来源渠道，第三方机构完善自身治理。  相似文献   

大健康视野下老年功能性力量评估——以武汉市老年太极人群为例     

肖剑  邹克宁  李小兰 《武汉体育学院学报》2019,53(2):74-80

采用文献法、测试法、数理统计等方法，以武汉市十三个行政区内528名以太极拳为主要体育健身方式的老年人为样本，以马步蹲起、弓箭步蹲起、肘撑侧桥、肘撑侧桥举腿等与日常生活活动相关联的四个基础动作为测试内容。研究表明，受试人群普遍存在下肢与躯干的功能性力量不足、左右侧肌肉链力量不均衡的问题。虽然样本人群经常进行以太极拳为主要形式的体育锻炼，但在锻炼过程中侧重于套路技能的演练，对功能性力量训练的认识不足及缺乏相应的训练方法，存在科学性盲区，需要引起重视。  相似文献   

Rater Certification Tests: A Psychometric Approach     

Yigal Attali 《Educational Measurement》2019,38(2):6-13

Rater training is an important part of developing and conducting large‐scale constructed‐response assessments. As part of this process, candidate raters have to pass a certification test to confirm that they are able to score consistently and accurately before they begin scoring operationally. Moreover, many assessment programs require raters to pass a calibration test before every scoring shift. To support the high‐stakes decisions made on the basis of rater certification tests, a psychometric approach for their development, analysis, and use is proposed. The circumstances and uses of these tests suggest that they are expected to have relatively low reliability. This expectation is supported by empirical data. Implications for the development and use of these tests to ensure their quality are discussed.  相似文献   

中美基础教育课外体育活动的比较研究     

俞皓天  汪晓赞 《武汉体育学院学报》2019,53(4):71-74

运用文献资料法、访谈法、比较分析法和逻辑法，对中美基础教育课外体育活动的价值取向、政策文件、组织管理、场地设施、运动时间及实施效果进行梳理、分析和比较，从中得出以下启示：要坚持课外体育活动健身育人的价值；学校体育政策要向课外体育活动倾斜，并注重政策的落实；构建课外体育活动的三级体系，促进家校社三方联动；加快社区体育建设，引导体育消费升级；布置体育作业，保证课外运动时间；立足实际问题，让学生从课外体育活动中受益。以邻为镜比较优劣得失，但不能生搬硬套，要从传统体育文化中吸收养分，促进青少年身心健康，促进我国课外体育活动改革与发展。  相似文献

我国体育产业发展与国民经济增长关系的实证研究     

李国  孙庆祝 《武汉体育学院学报》2019,53(1):43

运用文献资料、数理统计、VAR模型等方法，基于2005-2015年国民经济与体育产业发展统计指标数据，通过协整检验、向量误差模型、格兰杰因果检验、脉冲响应函数与方差分解等，对我国体育产业发展与国民经济增长之间的关系进行实证分析。研究结果为：（1）协整检验与向量误差模型分析显示，体育产业增加值与国民经济发展之间存在正相关长期协整关系，这种均衡关系具有反向修正机制，当均衡关系发生波动时，当期以-1.744 073倍的力度对前一期偏离状态进行调整，将其拉回到长期均衡状态；（2）格兰杰因果检验显示，体育产业发展是国民经济增长的Granger原因，但国民经济增长不是体育产业发展的Granger原因；（3）脉冲响应函数显示，国民经济波动对其自身发展与体育产业发展均产生负效应，体育产业对于自身冲击的脉冲响应呈正相关趋势，并且能够迅速促进国民经济发展。（4）方差分解显示，国民经济在其自身发展与体育产业发展中的作用呈逐渐增大之势，体育产业的影响则呈逐渐减小之势。最后，提出了"识别均衡关系：促进国民经济与体育产业互惠共生发展"、"衡量脉冲响应：降低国民经济与体育产业均衡发展负效应"、"重视方差分解：权衡国民经济与体育产业影响因素相对性"、"完善政策法规：优化国民经济与体育产业均衡发展制度环境"等促进国民经济与体育产业均衡发展的现实路径。  相似文献   

Guiding Low Spatial Ability Individuals through Visual Cueing: The Dual Importance of Where and When to Look     

Victoria A. Roach  Graham M. Fraser  James H. Kryklywy  Derek G.V. Mitchell  Timothy D. Wilson 《Anatomical sciences education》2019,12(1):32-42

Research suggests that spatial ability may predict success in complex disciplines including anatomy, where mastery requires a firm understanding of the intricate relationships occurring along the course of veins, arteries, and nerves, as they traverse through and around bones, muscles, and organs. Debate exists on the malleability of spatial ability, and some suggest that spatial ability can be enhanced through training. It is hypothesized that spatial ability can be trained in low-performing individuals through visual guidance. To address this, training was completed through a visual guidance protocol. This protocol was based on eye-movement patterns of high-performing individuals, collected via eye-tracking as they completed an Electronic Mental Rotations Test (EMRT). The effects of guidance were evaluated using 33 individuals with low mental rotation ability, in a counterbalanced crossover design. Individuals were placed in one of two treatment groups (late or early guidance) and completed both a guided, and an unguided EMRT. A third group (no guidance/control) completed two unguided EMRTs. All groups demonstrated an increase in EMRT scores on their second test (P < 0.001); however, an interaction was observed between treatment and test iteration (P = 0.024). The effect of guidance on scores was contingent on when the guidance was applied. When guidance was applied early, scores were significantly greater than expected (P = 0.028). These findings suggest that by guiding individuals with low mental rotation ability “where” to look early in training, better search approaches may be adopted, yielding improvements in spatial reasoning scores. It is proposed that visual guidance may be applied in spatial fields, such as STEMM (science, technology, engineering, mathematics and medicine), surgery, and anatomy to improve student's interpretation of visual content.
