“发而皆中节”——武术功夫的主体生成及启示

“发而皆中节”是指武术功夫无过不及的身体权变能力或境界,这需要经历合规矩的习拳规之 “中”、用规矩的查拳理之“中”、脱规矩的现主体之“中”的习拳历程。武术功夫习练是对中华优秀传统文化“发而皆中节”的创新传承与实践,武术功夫习练与践行中华优秀传统文化相辅相成,在合文化规矩之“中”与合自我天赋天性之“中”的功夫技艺中实现身心改变并生成身体主体,身体能力成为武术主体自我确证的依据,这是武术对传承中华优秀传统文化的实践智慧,也是武术研究的文化自觉。     

基于匹配点逐层过滤的岩体点云配准方法

岩体点云配准是岩体三维重建与分析的基础。经典的点云配准方法虽然能够很好地适用于普通点云,但对于岩体点云并不能获得足够的精度。由于岩体点云表面结构复杂,且大部分区域为平面,基于岩体点云的这些特点,提出通过几何特征逐层过滤匹配点的岩体点云配准算法,引入匹配点对的协方差矩阵的特征值和特征向量矩阵,以及曲率、主方向等几何特征逐层过滤匹配点对,精确地找到匹配点对。在不同岩体点云上的实验测试与分析结果表明,该算法在准确度上有明显优势。

Sport-based physical activity intervention on body weight in children and adolescents: a meta-analysis

Controversial results reported in past research pertaining to the effectiveness of sport-based physical activity interventions on weight loss. The purpose of this study was to assess the impact of sport-based physical activity intervention on body weight in children and adolescents using a meta-analysis. Academic Search Complete, Education Source, ERIC, Medline, ProQuest, PsycINFO and SportDiscus databases were searched from January 2000 to April 2015. Eighteen studies met following inclusion criteria: sport-based intervention studies; subjects aged 6–18 years; reported body weight; published in peer-reviewed journals written in English. The mean intervention duration was 17.72 weeks. The overall effect size (ES) was 0.52 (Cohen’s d (ES) = 0.52, 95% CI = 0.08, 0.95, P = 0.021), using a random effects model. Moderator analyses results showed that the Q statistic for the sport type (individual sport or team sport, Qbetween (Q_b) = 14.52, df = 1, P = 0.001) and diet control (Qbetween (Q_b) = 8.85, df = 1, P = 0.001), explained the heterogeneity of ESs. Our study showed that there was a moderate overall effect of sport-based physical activity intervention on body weight reduction. The team sport type (ES = 1.05, 95% CI = 0.44, 1.66) and diet control group (ES = 0.84, 95% CI = 0.26, 1.41) appeared to be more effective in reducing body weight.     

Can a non-Muslim Mass Shooter be a “Terrorist”?: A Comparative Content Analysis of the Las Vegas and Orlando Shootings

ABSTRACT

This study used the 2017 Las Vegas and 2016 Orlando mass shootings as case studies to explore alleged double standards in reporting of events featuring Muslim and non-Muslim mass perpetrators of violence. The study used framing theory and content analysis to examine Los Angeles Times and New York Times coverage of the shootings during the one week immediately following each event. Findings are consistent with previous literature and the researchers’ expectations. The Orlando shooting, carried out by a Muslim, was allotted more coverage despite the fact that it produced nine fewer fatalities than the Las Vegas shooting, perpetrated by a white non-Muslim. The analysis also showed that the examined newspapers were more likely to employ a “terrorism” frame in their coverage of the Orlando shooting than in their coverage of the Las Vegas shooting; link the Orlando mass shooting with the global war on terrorism; and to humanize Stephen Paddock, the white perpetrator of the Las Vegas shooting. Framing differences found in this study may contribute to downplaying the threat of white male gun violence, and to reinforcing fears of Islam and Muslims.     

从传递信息到营造体验:体育传播产品转型初探——基于传播游戏理论的考察

传播游戏理论强调传播作为一种主观性游戏的存在，体育传播与此具有天然的契合点。该文在界定体育传播产品内涵、分析传播游戏理论观点的基础上，提出体育传播产品要从传递信息走向营造体验，要开发体育视频资源，利用VR技术增强赛事体验，借助机器人提升体育信息传播速度，采用数据可视化增强体育传播的趣味性与观赏性。     

‘Experimental’ secondary modern education in Britain, 1948–1958

Studies of mid-twentieth century education in England and Wales have conventionally hinged on the 1944 Education Act, foregrounding policy over practice. This article considers the significance of the inter-war progressive educational movement for postwar educational developments. It presents a case study of one teacher who was active in the early ‘experimental’ years of secondary modern education, suggesting that this period was important in the making of ‘modern’ education. It seeks to complicate both negative and positive readings of ‘meritocracy’ in postwar educational history. This article also highlights the paucity of available source material for the study of the secondary modern school, arguing that attention should be paid to well-documented cases, placed in context.     

基于Cite Space的国内身体功能训练研究计量学分析

运用中国知网(CNKI)检索库进行检索,共查找到期刊文献115篇,其中国内期刊65篇,硕士论文31篇。通过Cite Space和中国知网(CNKI)文献分析功能,对国内身体功能训练研究进行计量学分析。研究的基本特征表现为:研究机构多,文献期刊发表数量较少,核心期刊占比较少,论文质量与数量之间存在差异。研究热点以身体功能训练为主,并突显了“功能训练”“训练”和“体育工作者”等关键词,作者合作比较少,仅形成数个微小的作者合作网络。     

Estimating fat-free mass in elite-level male rowers: a four-compartment model validation of laboratory and field methods

The purpose of this study was to investigate the accuracy of fat-free mass (FFM) estimates from two-compartment (2C) models including air displacement plethysmography (ADP), ultrasound (US), near-infrared interactance (NIR), and the Jackson and Pollock skinfold equation (SKF) against a criterion four-compartment (4C) model in elite male rowers. METHODS: Twenty-three elite-level male rowers (mean± SD; age 24.6 ± 2.2 years; stature: 191.4 ± 7.2 cm; mass: 87.2 ± 11.2 kg) participated in this investigation. All body composition assessments were performed on the same day in random order, except for hydrostatic weighing (HW), which was measured last. FFM was evaluated using a 4C model, which included total body water from bioimpedance spectroscopy, body volume from HW, and total body bone mineral via dual-energy X-ray absorptiometry. The major findings of the study were that the 2C models evaluated overestimated FFM and should be considered with caution for the assessment of FFM in elite male rowers. Future studies should use multiple-compartment models, with measurement of TBW and bone mineral content, for the estimation of FFM.     

高原体能训练对我国高水平优秀篮球运动员身体机能与形态的影响研究

摘要：以2015年中国男篮高原期间体能训练为研究对象，在高原训练过程中对中国男篮队员进行体能训练干预并进行追踪测试，并对高原前后身体机能与身体形态的变化进行深入研究，以期对高水平篮球运动员的高原体能训练进行科学化探索。方法：使用韩国Bio Space公司Inbody3.0体成分测试仪分别在上高原和下高原前测试身体成分；使用贝克曼库尔特公司GEN.S血细胞分析仪等仪器分别在上高原、高原中和下高原前测试身体机能。结果： HB、RBC和HCT在高原训练后都发生了显著的变化（P<0.01）；BUN与CK呈现先升高、再降低趋势；T与C则先降低、后升高；T/C则呈逐步上升趋势，但无显著性差异；身体成分中除了脂肪含量、腰臀比和体脂百分比有显著降低外（P<0.05），其他指标没有显著变化（P>0.05）。结论： 1）高原体能训练可以显著提高篮球运动员血液携氧能力，这种能力在高原训练第11天的测试中发现有明显的提高，并于第21天达到非常显著水平。因此要改善篮球运动员机能水平，高原体能训练应至少持续21天。2）BUN和CK呈先上升后下降的趋势，且与高原体能训练负荷量的变化密切相关，因此BUN和CK可以作为今后高原体能训练负荷量控制的参考指标。3）T和C呈先下降后上升趋势，T/C则呈升高趋势，说明此次高原训练负荷安排科学合理，运动员没有发生疲劳现象，机体合成代谢能力得到提高。4）高原体能训练可以降低篮球运动员的体脂含量，但对肌肉围度的影响则与高原训练的高度、形式及负荷有关。5）此次高原体能训练模式可以作为其他高水平篮球队进行高原体能训练的参考。
