The present investigation was carried out to examine the incidence and pattern of injuries in adolescent multisport athletes from youth sports academy. Injury data were prospectively collected from 166 athletes during the seasons from 2009 to 2014. A total of 643 injuries were identified, 559 (87.0%) were time-loss injuries. The overall injury incidence was 5.5 (95% confidence interval CI: 5.1–6.0), the incidence of time-loss injuries was 4.8 (95% CI: 4.4–5.2), the incidence of growth conditions was 1.2 (95% CI: 1.0–1.4) and incidence of serious injuries was 0.6 (95% CI: 0.5–0.8) per 1000?h of exposure. The prevalence of overuse injuries was 50.3%. Growth conditions represented 20.0%. Most of the injuries (67.0%) involved the lower extremities, and both foot and ankle were the most predominant injured body parts (22.0%). Knee injuries were mostly from overuse (50 vs. 23, p?=?.02), whereas foot and ankle injuries resulted from an acute mechanism (94 vs. 31, p?<?.0001). Minor and moderate injuries accounted for 87.0%. Muscle, tendon and osteochondrosis injuries accounted for 52.0% of all injuries. Comparing groups, squash sport was having the highest injury incidence (8.5 injuries per athlete). Higher exposure was associated with greater overuse relative risk (RR?=?1.03, 95% CI: 1.01–1.014, p?<?.001). In conclusion, the results of this study identified a high incidence of injuries in this youth sports population. Striking was the prevalence of overuse injuries of 50%, which suggests the need for injury prevention protocols for adolescent highly trained athletes.  相似文献

韩国经济起飞的日本因素     

闰华芳 《大连大学学报》2015,(1):80-84

20世纪60年代,韩国制定了出口导向的经济发展计划,但韩国经济凋敝,缺乏工业化所需的庞大的资金和先进的技术。而通过日韩关系正常化,取得日本的赔偿,是导入外资的重要途径。1965年《日韩协定》签定以来,日本对韩国的援助以及技术交流在一定程度上支持着韩国的越南特需,并在第2个5年计划期间作为主要财源,为韩国的经济发展带来活力,另一方面,日本对韩国的援助和投资,也开拓了日企的市场,提高日本对韩国的出口,并使韩国对日贸易长期处于赤字状态。  相似文献   

Coordinating multiple representations of polynomials: What do patterns in students' solution strategies reveal?     

《Learning and Instruction》2017

We investigate the strategies used by 64 advanced secondary mathematics students to identify whether a given pair of polynomial representations (graphs, tables, or equations) corresponded to the same function on an assessment of coordinating representations. Participants also completed assessments of domain-related knowledge and background skills. Cluster analysis of strategies by representation pair revealed patterns in the participants' strategy use. Two clusters were identifiable on tasks that required matching equations to graphs and graphs to tables. We identified overlap between these two clusters, suggesting that while the representation pair influenced strategy choice, there was also a general distinction between students who used more and less sophisticated strategies. However, students who used more sophisticated coordination strategies were similar to the others on measures of domain-specific knowledge or background skills. We consider implications for future investigations testing interventions to promote coordinating representations.  相似文献   

论死刑复核程序的完善路径     

陈香酥 《十堰职业技术学院学报》2011,24(5):45-47

死刑复核程序是我国刑事诉讼中的一道特有程序。自死刑核准权统一收归最高人民法院之后,死刑复核程序的应有功能仍未完全发挥。近期发生的一系列死刑案件更使得死刑复核程序的完善再次成为人们极为关注的话题,死刑复核程序的修改也必将成为刑事诉讼法修改的规划内容之一。  相似文献

Formative Assessment: A Meta‐Analysis and a Call for Research     

Neal Kingston  Brooke Nash 《Educational Measurement》2011,30(4):28-37

An effect size of about .70 (or .40–.70) is often claimed for the efficacy of formative assessment, but is not supported by the existing research base. More than 300 studies that appeared to address the efficacy of formative assessment in grades K‐12 were reviewed. Many of the studies had severely flawed research designs yielding uninterpretable results. Only 13 of the studies provided sufficient information to calculate relevant effect sizes. A total of 42 independent effect sizes were available. The median observed effect size was .25. Using a random effects model, a weighted mean effect size of .20 was calculated. Moderator analyses suggested that formative assessment might be more effective in English language arts (ELA) than in mathematics or science, with estimated effect sizes of .32, .17, and .09, respectively. Two types of implementation of formative assessment, one based on professional development and the other on the use of computer‐based formative systems, appeared to be more effective than other approaches, yielding mean effect size of .30 and .28, respectively. Given the wide use and potential efficacy of good formative assessment practices, the paucity of the current research base is problematic. A call for more high‐quality studies is issued.  相似文献   

国立国术体育师范专科学校的产生、发展及启示     

刘帅兵  赵光圣 《上海体育学院学报》2020,(2):87-94

国立国术体育师范专科学校基于中西方文化冲突下的文化自觉而产生与发展,受政治、教育、文化等因素影响,引进西方自然主义体育,推崇本土国粹武术,注重军事训练,在发展过程中秉承培育师资和沟通中西方体育的办学目的,形成了完整的学校行政组织,以及课程设置、师资聘用、学生管理等制度,并通过访问和比赛提升社会影响力。对当代学校武术教育的启示体现为:学校武术教育应坚守社会责任担当,为社会培养所需的人才;强化武术文化认同,增强民族文化自信,规避对西方体育文化的依附和模仿;推行多元教育形式联动机制,维系武术教化的过程性。  相似文献
