Dynamical analysis of winter terrain park jumps

Jump features in winter terrain parks frequently pose a hazard to patrons and may represent a significant liability risk to winter resorts. By performing a simple dynamic analysis of terrain park jumps, the relative risk to impact injuries for any proposed jump design can be quantified thereby allowing terrain park designers to minimize the risk from this class of injury.     

我国优秀射箭运动员损伤及康复研究

运用观察法、问卷调查法、数理统计法对我国大部分省(市)一线射箭运动员的损伤规律进行研究。研究认为,我国优秀射箭运动员受伤率为73.3%,男、女差异均比较显著,女比男高;专项提高、最佳竞技状态阶段较高;准备期损伤率较高;运动级别、比赛名次与受伤率无显著差异;受伤部位以肩部、腰部、颈部为主。随着训练年限的延长,运动级别、比赛名次提高,肩部损伤递减,腰部损伤增加;男性以肩部损伤常见,女性腰部损伤较多;损伤性质多为慢性损伤;受伤原因依次为:缺乏准备活动、恢复不好、参加其他活动、保护意识差、局部负荷过大、厌倦训练、老伤、体能训练少、教练员水平不高、加练;运动员在伤后采取的措施,全程各训练阶段具有显著的差异。在此基础上,提出康复训练手段与措施。     

体育教师工作倦怠现状的调查与分析

工作倦怠产生于长期的工作压力,表现为情绪、态度和行为的衰退状态,将直接导致出现情绪衰竭、人格解体和低成就感。体育教师不仅担负着体育教学的任务,还承担着基础教育改革和发展及素质教育的伟大历史重任。关注体育教师工作倦怠的现状、消极影响,产生的根源与措施研究具有深远意义。

论自省慎独在新闻工作者道德人格培育中的作用

自省、慎独是儒家提出的重要修身方法,几千年来对人们修身齐性,追求高尚的道德情操起到了巨大的促进作用,今天仍是当代新闻工作者培育高尚道德人格的重要途径。新闻工作者道德认识、道德情感、道德意志、道德信念、道德习惯等的养成都与自省、慎独密切相关。     

Factors associated with concussion-symptom knowledge and attitudes toward concussion care seeking in a national survey of parents of middle-school children in the US

Background:Developing appropriate concussion prevention and management paradigms in middle school(MS)settings requires understanding parents’general levels of concussion-related knowledge and attitudes.This study examined factors associated with concussion-symptom knowledge and care-seeking attitudes among parents of MS children(aged 10-15 years).Methods:A panel of 1224 randomly selected U.S.residents,aged ≥18 years and identifying as parents of MS children,completed an online questionnaire capturing parental and child characteristics.The parents’concussion-symptom knowledge was measured using 25 questions,with possible answers being“yes”,“maybe”,and“no”.Correct answers earned 2 points,“maybe”answers earned 1 point,and incorrect answers earned 0 point(range:0-50;higher scores=better knowledge).Concussion care-seeking attitudes were also collected using five 7-point scale items(range:5-35;higher scores=more positive attitudes).Multivariable ordinal logistic regression models identified predictors of higher scores.Models met proportional odds assumptions.Adjusted odds ratios(aORs)with 95%confidence intervals(95%CIs)(excluding 1.00)were deemed statistically significant.Results:Median scores were 39(interquartile range:32-44)for symptom knowledge and 32(interquartile range:28-35)for care-seeking attitude.In multivariable models,odds of better symptom knowledge were higher in women vs.men(aOR=2.28;95%CI:1.71-3.05),white/non-Hispanics vs.other racial or ethnic groups(aOR=1.88;95%CI:1.42-2.49),higher parental age(10-year-increase aOR=1.47;95%CI:1.26-1.71),and greater competitiveness(10%-scale-increase aOR=1.24;95%CI:1.13-1.36).Odds of more positive care-seeking attitudes were higher in white/non-Hispanics vs.other racial or ethnic groups(aOR=1.45;95%CI:1.06-1.99)and in older parental age(10-year-increase aOR=1.24;95%CI:1.05-1.47).Conclusion:Characteristics of middle school children’s parents(e.g.,sex,race or ethnicity,age)are associated with their concussion-symptom knowledge and care-seeking attitudes.Parents’variations in concussion knowledge and attitudes warrant tailored concussion education and prevention.     

Misconceptions about traumatic brain injury among students preparing to be special education professionals

The researchers performed a survey study to determine the effectiveness of collegiate programmes in dispelling common misconceptions about traumatic brain injury (TBI) while preparing undergraduate and graduate students for special education (SpEd) careers. Respondents included 136 undergraduate and 147 graduate SpEd students in their final semesters before obtaining degrees. Each completed an 18‐item true/false survey about TBI and the associated recovery process. Results were compared with survey responses from 318 lay public respondents who participated in a previous study. Two major findings emerged: (a) no significant differences existed in misconception endorsement between SpEd students completing Bachelor's versus Master's degrees; and (b) graduating students in SpEd teacher preparation programmes endorsed similar misconceptions as lay public respondents; hence, these programmes do not appear effective in dispelling common TBI misconceptions. Improving academic preparation for special educators regarding TBI is imperative for effectively identifying, assessing and serving student survivors.
