考证历代文献可知,"和"的本义指唱歌时候声音相应,引申为不同事物的协调统一。"和谐"首先被使用在音律上,用来指乐器和音律的协调相应,也指自然万物的协调统一。古代对乐理与自然和谐的阐释,被进一步引申,应用到家庭和国家等社会政治领域中,其词性有名词、动词两种:作为名词是指各种事物"各安其位、不相凌越、各得其理、相互配合、相互回应",作为动词是指使家庭、社会、国家和谐。  相似文献

结合风险管理理论和博弈理论,运用定量化模型研究了风险关联对企业信息系统安全投资的影响。通过对比非合作博弈和社会最优下的自我防御投资和网络安全保险水平,提出相应的协调机制。研究结果表明:当关联性风险趋于很小时,自我防御投资水平随其潜在安全损失的上升而增大;企业在进行信息系统安全投资时往往会忽略对其他企业的边际外部成本或收益的影响,这种负外部性特征会导致企业自我防御投资和网络安全保险水平均低于社会最优化水平。政府通过补贴企业自我防御投资可以在一定程度上协调企业的风险管理决策,进而改善企业安全水平,有效提高社会福利。  相似文献

This study investigated differences in generic and soccer specific motor coordination, as well as speed and agility depending on age and maturity in elite youth soccer players (U10-U15, N = 619). Measurements included body height, body weight and sitting height to estimate age at peak height velocity (APHV); three Körperkoordinationstest für Kinder subtests (i.e. jumping sideways (JS), moving sideways (MS), balancing backwards (BB)) to assess generic motor coordination; the UGent dribbling test for soccer specific motor coordination; a 5m/30m sprint and T-test for speed and agility, respectively. Age specific z-scores of the predicted APHV identified players as earlier, on time or later maturing. (M)ANOVA analyses showed significant age by maturity interaction effects for the speed and agility test cluster, revealing maturity related differences in U14 and U15 players. Next to an overall higher performance with age for all test clusters (η2 0.080–0.468), earlier maturing players outperformed their later maturing peers in 5m/30m sprinting. The opposite was seen for JS and BB. So, players’ maturity status should be taken into account to adequately value performance in talent identification. Also, the focus on characteristics that appear to be minimally biased by an earlier maturational timing (i.e. motor coordination) should be increased.  相似文献

The purpose of this study was to examine the impact of age on running mechanics separately for male and female runners and to quantify sex differences in running mechanics and coordination variability for older runners. Kinematics and kinetics were captured for 20 younger (10 male) and 20 older (10 male) adults running overground at 3.5 m · s?1. A modified vector coding technique was used to calculate segment coordination variability. Lower extremity joint angles, moments and segment coordination variability were compared between age and sex groups. Significant sex–age interaction effects were found for heel-strike hip flexion and ankle in/eversion angles and peak ankle dorsiflexion angle. In older adults, mid-stance knee flexion angle, ankle inversion and abduction moments and hip abduction and external rotation moments differed by sex. Older compared with younger females had reduced coordination variability in the thigh–shank transverse plane couple but greater coordination variability for the shank rotation–foot eversion couple in early stance. These results suggest there may be a non-equivalent aging process in the movement mechanics for males and females. The age and sex differences in running mechanics and coordination variability highlight the need for sex-based analyses for future studies examining injury risk with age.  相似文献

The purpose of this study was to compare arm–leg coordination and kinematics during 100 m breaststroke in 26 (8 female; 18 male) specialist breaststroke swimmers. Laps were recorded using three 50-Hz underwater cameras. Heart rate and blood lactate were measured pre- and post-swim. Arm–leg coordination was defined using coordination phases describing continuity between recovery and propulsive phases of upper and lower limbs: coordination phase 1 (time between end of leg kick and start of the arm pull phases); and coordination phase 2 (time between end of arm pull and start of leg kick phases). Duration of stroke phases, coordination phases, swim velocity, stroke length (SL), stroke rate (SR) and stroke index (SI) were analysed during the last three strokes of each lap that were unaffected by turning or finishing. Significant changes in velocity, SI and SL (P < 0.05) were found between laps. Both sexes showed significant increase (P < 0.05) in heart rate and blood lactate pre- to post-swim. Males had significantly (P < 0.01) faster swim velocities resulting from longer SLs (P = 0.016) with no difference in SR (P = 0.064). Sex differences in kinematic parameters can be explained by anthropometric differences providing males with increased propelling efficiency.  相似文献

摘要:学校体育设施社会化开放是我国现行体育事业发展的一项基本政策措施。然而关于学校体育设施社会化开放的立法规定仍然存在一些不协调的地方,需要我们在制度上完善设计,在政策措施上需要有相关的立法予以保障。通过文献分析法与比较分析法的运用,可以发现从我国现行立法体制来看,中央立法未能确立学校体育设施社会化开放立法的基本框架,而地方关于学校体育设施社会化开放立法的合法性与可操作性又不足,中央立法与地方立法不协调已严重制约我国学校体育设施社会化开放政策的实施。基于统计分析与规范论证方法的考察,建议我国应完善学校体育设施社会化开放立法,加强《体育法》顶层设计、实现学校体育社会化立法的纵向与横向协调,同时完善体育立法技术,保障学校体育设施社会化开放制度的实施及其效果。通过科学谋划与系统推进才能不断创新、不断完善我国学校体育设施社会化开放制度的有效实施,惠及社会大众,为我国体育治理现代化事业不断添砖加瓦,巩固国家治理现代化的事业大局。  相似文献
