Injury rates in professional soccer players during Ramadan     

Chamari K  Haddad M  Wong del P  Dellal A  Chaouachi A 《Journal of sports sciences》2012,30(Z1):S93-102

Many of the socio-cultural lifestyle and dietary changes that take place during Ramadan may affect the risk of injury in athletes, but little evidence is available. The aim of the present study was to examine the effects over two consecutive years of the holy month of Ramadan on injury rates in 42 professional players of a Tunisian top-level professional soccer team. Players were retrospectively organized into fasting and non-fasting groups and monitored for 3 months: 4 weeks before Ramadan, during the month of Ramadan (4 weeks), and 4 weeks after Ramadan each year. During Ramadan, training started at 22.00 h. The circumstances (training/match) and mechanism of injury (traumatic/overuse) were recorded. No significant differences between the three periods were observed for weekly mean training load, training strain, training duration, and Hooper's Index (quality of sleep, and quantities of stress, delayed-onset muscle soreness, and fatigue). Compared with non-fasting players, fasters had a lower (P < 0.05) Hooper's Index and stress during and after Ramadan. No significant difference in injury rates was observed between fasting and non-fasting players. Nevertheless, the rates of non-contact (6.8 vs. 0.6 and 1.1) and training overuse (5.6 vs. 0.6 and 0.5) injuries were significantly higher in fasting players during the month of Ramadan than before or after Ramadan. In conclusion, Ramadan, along with the corresponding changes in nutritional habits, sleeping schedule, and socio-cultural and religious events, significantly increased overuse and non-contact injuries in fasting players despite the fact that the training load, strain, and duration were maintained.  相似文献   

Growth behavior of publications and patents: A comparative study on selected Asian economies     

Chan-Yuan Wong  Kim-Leng Goh 《Journal of Informetrics》2010,4(4):460-474

This study attempts to model the growth behavior of the number of publications and patents of South Korea, Taiwan, Japan and Malaysia. Three competing growth functions, namely, simple logistic growth function, bi-logistic growth function and logistic function within a dynamic carrying capacity were considered. The findings provide insight to the diffusion process of science and technology, often measured by the number of publications and patents, respectively. The function that provides the best fit to the observed data was opted for explaining the diffusion process. The function with the best fit is the bi-logistic growth function for the number of publications as well as the number of patents of South Korea and Taiwan, the logistic growth function within a dynamic carrying capacity (LGDCC) for the number of publications and the bi-logistic growth function for the number of patents of Japan, and the LGDCC for the number of publications and simple growth function for the number of patents of Malaysia. The results suggest a dynamic self-propagating growth for the science and technology, and thereby a transition from science and technology-push to market-pull growth for South Korea and Taiwan. While a similar transition was observed for the technology of Japan, the growth in science had entered a maturity stage. On the other hand, the growth potential in science is dynamic for Malaysia, but its technological advancement is relatively lower and static compared to the other economies.  相似文献

Effectiveness of Multimedia Pedagogical Agents Predicted by Diverse Theories: a Meta-Analysis     

Castro-Alonso  Juan C.  Wong  Rachel M.  Adesope  Olusola O.  Paas  Fred 《Educational Psychology Review》2021,33(3):989-1015

Multimedia pedagogical agents are on-screen characters that allow users to navigate or learn in multimedia environments. Several agents’ characteristics may moderate their instructional effectiveness, including appearance, gender, nonverbal communication, motion, and voice. Here, we conducted a meta-analysis to test hypotheses from diverse theories predicting the effects of these agents’ characteristics. We tested predictions of cognitive load theory, cognitive theory of multimedia learning, computers are social actors, social agency theory, uncanny valley, and the action observation network. Our meta-analysis of 32 effect sizes (N?=?2104) revealed a small overall effect (g+?=?0.20), showing that learning with multimedia pedagogical agents was more effective than learning without these agents. As predicted by the redundancy effect of cognitive load theory and the coherence principle of cognitive theory of multimedia learning, 2D agents (g+?=?0.38) tended to be more effective than 3D agents (g+?=?0.11). As predicted by the computers are social actors hypothesis, most of the agents’ characteristics, including nonverbal communication, motion, and voice, appeared not to moderate their effectiveness. We conclude that multimedia pedagogical agents help learning through multimedia, and that students may be able to learn similarly from different types of agents.

Motivation beliefs of secondary school teachers in Canada and Singapore: A mixed methods study   总被引：1，自引：0，他引：1  

Robert M. Klassen  Wan Har Chong  Vivien S. Huan  Isabella Wong  Allison Kates  Wanwisa Hannok 《Teaching and Teacher Education》2008

A mixed methods approach was used to explore secondary teachers’ motivation beliefs in Canada and Singapore. Results from Study 1 revealed that socio-economic status (SES) was the strongest predictor of school climate in Canada, and that collective efficacy mediated the effect of SES on school climate in Singapore, but not in Canada. In Study 2, interviews were conducted with 10 teachers in Canada and 14 teachers in Singapore. Teachers in both settings discussed students’ social and behavior problems, but the range of the social problems was greater in Canada than in Singapore, and had a stronger impact on teachers’ motivation beliefs.  相似文献

Pedagogy of the Spirit: Comparing Evangelical and Latter-day Saint Youth Self-Reported In-Class Spiritual Experiences     

Arch Chee Keen Wong  Anthony Sweat  Ryan Gardner 《Religious education (Chicago, Ill.)》2017,112(5):569-584

This study statistically analyzes data from 756 evangelical and Latter-day Saint youth regarding their perceived in-class spiritual experiences of twenty items related to Christian theology. The data indicates similar spiritual outcomes between the two groups, with no statistically significant differences between eleven of the twenty spiritual experience items. However, evangelical participants most highly reported affective spiritual outcomes and least commonly reported action-oriented spiritual outcomes, while Latter-day Saint youth most highly reported action-oriented spiritual outcomes and least commonly reported cognitive spiritual outcomes. Action-oriented spiritual outcomes constitute the greatest difference between the two groups. We explore how the differences between evangelical and Latter-day Saint pedagogy and theology might account for these differences.  相似文献
