Test-taking is an emotion-laden event for many students. Typically, negative emotions are highest at the start of an examination and are replaced by positive emotions as the exam progresses. The impact of computer-based testing and immediate score reporting on students' emotions has not been examined. In Study 1, we evaluated university students’ emotions at the end of a computer-based exam and found positive emotions more strongly endorsed than negative. In Study 2, we replicated this finding and used a quasi-experimental pre-post design to examine how emotions changed in response to real examination scores. Exam scores presented immediately had significant positive effects on relief, pride, and hope and negative effects on anxiety and shame even after controlling for the corresponding emotion at the end of the exam. The one exception was anger, which was not impacted by examination score. No interaction effects were found.  相似文献

为中国足球减压———基于国人过高期望的反思   总被引:2,自引:1,他引:1  
在我们发泄着对中国足球的各种不满与愤怒的时候,我们也应该思考一下这些不满的根源在何处,也应该反思一下这种愤怒是否真的有助于中国足球的发展.正是基于这种思考,通过查阅相关文献和资料,批判性地思考国人对中国足球期望过高的因为和根源,同时反思了这种沉重的压力所带来的负面影响,从而提出为中国足球减压的倡议.同时呼吁国人:合理地定位中国足球,纠正急于求成的冒进行为,理性地分析中国足球在发展中遇到的挫折,循序渐进地发展中国足球.  相似文献

摘要:通过文献资料法、问卷调查法、专家访谈法、数理统计法等,从中学体育教师、学校领导角度出发对中学校园足球文化结构进行了理论假设与验证,同时调查了体育教师对中学校园足球文化结构的认知差异情况。结果表明:1)通过综述以往研究,提炼出了中学校园足球文化由政策解读、校本实际、自我能力、学生情况、地域文化、社会环境、足球核心价值7个维度构成,并得到了良好的验证。2)通过进行单因素方差分析发现:中学体育教师因为教龄、性别、任教地区、任教阶段的不同,对中学校园足球文化结构的认知存在一定的差异。立足于中学体育教师和学校领导展开的调查,旨在为中学校园足球文化的基本结构及内涵认识情况进行了解,中学的校园足球文化参与者有了清晰的认识,就能够在一定程度上引领学生参与和学习正确的足球运动,从而为中学校园足球文化的构建奠定一定的理论基础。通过对中学体育教师认识差异的原因进行科学的分析和讨论,积极探索当前社会背景下构建中学校园足球文化的方法和途径,为中学特色校园足球文化的可持续发展提供积极的理论基础,也为中学校园足球的开展提供积极的理论借鉴。  相似文献

新浪微博替代计量指标特征分析   总被引:4,自引:1,他引:3  
通过对新浪微博替代计量指标进行统计分析,探索中文环境下替代计量指标的特征和规律。研究发现:新浪微博替代计量指标覆盖率不足1%,但由于追踪时间和追踪对象的局限,该数字可能被严重低估;新浪微博关注和讨论较多的论文来自"综合""生物化学、遗传学与分子生物学""保健科学""医学"及"生命科学"等学科;新浪微博替代计量指标的期刊分布满足对数曲线规律,除著名的综合性期刊如Nature等,预印本平台arXiv和开放存取期刊PLoS ONE等也获得了较多关注,生物学和医学的"明星期刊"最多;新浪微博主要关注最新论文,正式出版180天内受到关注的论文比例高达68.66%,同时也会关注经典论文;新浪微博发布者倾向宣传、推介和评论贴近生活、趣味性强、实用性高、涉及生命健康的学术论文,传递出引文无法体现的社会价值和学术价值;新浪微博替代计量指标呈现出显著的离散和集中分布特点,5.1%的学术论文获得了50%的新浪微博关注。此外,受新浪微博关注的论文在全球范围内获得远高于平均水平的关注度。  相似文献

This study investigated the evolution of physical and technical performances in the English Premier League (EPL), with special reference to league ranking. Match performance observations (= 14,700) were collected using a multiple-camera computerised tracking system across seven consecutive EPL seasons (2006–07 to 2012–13). Final league rankings were classified into Tiers: (A) 1st–4th ranking (= 2519), (B) 5th–8th ranking (= 2965), (C) 9th–14th ranking (= 4448) and (D) 15th–20th ranking (= 4768). Teams in Tier B demonstrated moderate increases in high-intensity running distance while in ball possession from the 2006–07 to 2012–13 season (< 0.001; effect size [ES]: 0.68), with Tiers A, C and D producing less pronounced increases across the same period (< 0.005; ES: 0.26, 0.41 and 0.33, respectively). Large increases in sprint distance were observed from the 2006–07 to 2012–13 season for Tier B (< 0.001; ES: 1.21), while only moderate increases were evident for Tiers A, C and D (< 0.001; ES: 0.75, 0.97 and 0.84, respectively). Tier B demonstrated large increases in the number of passes performed and received in 2012–13 compared to 2006–07 (< 0.001; ES: 1.32–1.53) with small-to-moderate increases in Tier A (< 0.001; ES: 0.30–0.38), Tier C (< 0.001; ES: 0.46–0.54) and Tier D (< 0.001; ES: 0.69–0.87). The demarcation line between 4th (bottom of Tier A) and 5th ranking (top of Tier B) in the 2006–07 season was 8 points, but this decreased to just a single point in the 2012–13 season. The data demonstrate that physical and technical performances have evolved more in Tier B than any other Tier in the EPL and could indicate a narrowing of the performance gap between the top two Tiers.  相似文献

Dribbling speed in soccer is considered critical to the outcome of the game and can assist in the talent identification process. However, little is known about the biomechanics of this skill. By means of a motion capture system, we aimed to quantitatively investigate the determinants of effective dribbling skill in a group of 10 Under-13 sub-elite players, divided by the median-split technique according to their dribbling test time (faster and slower groups). Foot-ball contacts cadence, centre of mass (CoM), ranges of motion (RoM), velocity and acceleration, as well as stride length, cadence and variability were computed. Hip and knee joint RoMs were also considered. Faster players, as compared to slower players, showed a 30% higher foot-ball cadence (3.0 ± 0.1 vs. 2.3 ± 0.2 contacts · s?1, < 0.01); reduced CoM mediolateral (0.91 ± 0.05 vs. 1.14 ± 0.16 m, < 0.05) and vertical (0.19 ± 0.01 vs. 0.25 ± 0.03 m, < 0.05) RoMs; higher right stride cadence (+20%, < 0.05) with lower variability (< 0.05); reduced hip and knee flexion RoMs (< 0.05). In conclusion, faster players are able to run with the ball through a shorter path in a more economical way. To effectively develop dribbling skill, coaches are encouraged to design specific practices where high stride frequency and narrow run trajectories are required.  相似文献

Abstract

This paper explores multiple and complex relationships between football (soccer), politics, and the economy in postcolonial Zambia. Based on archival and oral sources collected in Zambia, the paper argues that President Frederick Chiluba’s government failed to support football development when it came into power in 1991 because it was elected on a platform of liberalizing the collapsing national economy. Chiluba privatized state-owned companies that were sponsoring the game resulting in the plummeting of the local standards and migration of talented footballers abroad in search of better livelihoods. Furthermore, the paper argues that while the exodus of talented footballers led to the deterioration of the standards of the local league, their transnational experience boosted the performance of the Zambia national football team. This led to the emergence of one of the best national teams the country has ever had. Unfortunately, this particular team perished in the Gabon air disaster in 1993 following the government’s disinvestment in the game. However, a few months after the disaster, the country managed to rebuild a national football team, which emerged as runners up to Nigeria in the 1994 African Cup of Nations final as a result of a large pool of local and foreign-based football players.  相似文献
