追问与省思：面子心理导向下的中国武术发展研究

摘要：国民文化心态综合体现着中华文明的印记与传统文化的培塑,是一种对自己本民族文化与价值观念所持有的总体态度,容易受到社会心理导向的干预,进而对国民文化认知产生影响。主要运用文献资料法,从家族面子与武术的“入奥”追求,他人面子与武术“能打”的证明以及自我面子与武术的“优越”情结3个层面,探讨了当前中国武术的发展问题。研究认为：不可兼容的中西文化差异,特殊的国民文化心态以及不全面的武术本土化认知,导致中国武术在对“自我认知”与“他者认知”的时候出现误区。在此基础上,提出：要实现中国武术的体面发展应该坚守文化自觉的主张,加快武术现代化转型;树立文化自信的观念,摆正武术的文化姿态;培育自尊自强的国民心态,确保武术的理性发展。惟其如此,才能从更全面、更客观的视角看待武术、发展武术。

从“双减”谈体育教育的价值走向与创新发展

基于“双减”政策背景探讨体育教育的价值走向与创新发展尤为重要与现实。分析了“双减”政策对体育教育的多元期待,不仅期待体育教育的发展弊端尽早尽快消除,期待体育教育的操作流程更加注重以人为本,还期待体育教育的相关政策落实要能分层分类分项推进。从永恒不变、动态发展、优化完善等内涵特征较为系统地梳理了“双减”背景下体育教育的价值追求。提出了“双减”落实中体育教育发展的构想,诸如体育教育发展的着力点需要瞄准全体学生全面发展路径的优化,其层次感需要聚焦体育课程教学改革内涵的提升,其满意度需要集中体现家校社协同共育的结果。旨为进一步完善体育教育基础理论和在“双减”背景下促进体育教育更好更快地发展提供重要的借鉴。     

Energy turnover during 24 hours and 6 days of adventure racing

Abstract

Energy turnover was assessed in two conditions of mixed ultra-endurance exercise. In Study 1, energy expenditure and intake were measured in nine males in a laboratory over 24 h. In Study 2, energy expenditure was assessed in six males during an 800-km Adventure race (mean race time 152.5 h). Individual correlations between heart rate and oxygen uptake ([Vdot]O₂) were established during pre-tests when kayaking, cycling, and running. During exercise, energy expenditure was estimated from continuous heart rate recordings. Heart rate and [Vdot]O₂ were measured regularly during fixed cycling work rates to correct energy expenditure for drift in oxygen pulse. Mean energy expenditure was 18,050 ± 2,390 kcal (750 ± 100 kcal · h^?1) and 80,000 ± 18,000 kcal (500 ± 100 kcal · h^?1) in Study 1 and Study 2 respectively, which is higher than previously reported. Energy intake in Study 1 was 8,450 ± 1,160 kcal, resulting in an energy deficit of 9,590 ± 770 kcal. Body mass decreased in Study 1 (?2.3 ± 0.8 kg) but was unchanged in Study 2. Fat mass decreased in Study 2 (?2.3 ± 1.5 kg). In Study 1, muscle glycogen content decreased by only 60%. Adventure racing requires a high energy expenditure, with large inter-individual variation. A large energy deficit is caused by inadequate energy intake, possibly due to suppressed appetite and gastrointestinal problems. The oxygen pulse, comparing start to 12 h of exercise and beyond, increased by 10% and 5% in Study 1 and Study 2 respectively. Hence, estimations of energy expenditure from heart rate recordings should be corrected according to this drift.     

Dechlorination by combined electrochemical reduction and oxidation

INTRODUCTION Chlorinated phenols compounds used widely in industry were intentionally or inadvertently released into environment in large quantities. These chlorin-ated aromatic compounds have strong resistance to physical, chemical and biological treatments and have been listed as a priority pollutant by the U.S. Envi-ronmental Protection Agency (Lin and Tseng, 1999). Wastewater containing chlorophenols has malodor-ous odor, high toxicity, bioaccumulation and car-cinogenic potential. …     

论低碳文化与文明前景

低碳减排是当前全球关注的焦点问题之一。低碳减排不仅对人类社会发展是有益的,同时也是人类可持续发展的必然要求。维持自然界的碳循环平衡本身就是生态文明的内在要求,低碳文化也是生态文化的内在要求。将低碳上升到文化的高度、建立低碳文化,对维持碳循环平衡和实行低碳减排是有重要作用和价值的。低碳文化的建立需要将低碳观念与人们的世界观、科技观、教育观等多方面进行关联。     

考虑低碳节能的小城镇居住区规划设计仿真

随着工业化和城市化进程推进,小城镇居住区的低碳节能规划设计关系到城市发展和人们生活健康。考虑低碳节点效果,提出一种基于二氧化碳含量和温度自回归分析的小城镇居住区规划设计模型。模型设计包括了城镇的楼宇建筑设计、绿化景观和风景园林设计等。通过可持续发展的建筑规划选址、合理的土地利用、适宜的功能分区、安全便捷的交通系统等子系统设计完成居住区的整体规划。采用功能分区合并技术,把绿地系统分自然绿地、居住绿地、活动绿地、庭院绿地。规划区域主要分为生活区和活动区、绿色生态区、商业区等四大区域,以光照、温度、湿度和绿化植物的碳吸收和释氧量为自回归参数进行数学建模。充分利用的南向采光和立体采光,使得居住区的光照强度增加。仿真实验结果得出,该模型具有较好的低碳节能效果,居民满意度提高。
