利用肌电反馈技术进行心理控制训练研究   总被引：10，自引：2，他引：8  

王惠民  崔秋耕 《体育科学》1991,(4)

本文采用以肌电反馈技术为核心的训练方法,对八名(男5,女3)国家游泳、体操、举重、跳水集训队队员进行了心理控制训练,经统计比较训练前、后自身肌电值,两者差异非常显著。这说明肌电反馈对心理控制有很强的辅助效果,在一定程度上提高了运动员的自我心理控制能力,并有助于建立良好的心理平衡状态,发挥运动最佳竞技操作水平。  相似文献

太极，无极而生，阴阳之母也。太极是体，阴阳是体中之气。拳，权也，所以权物而知其轻重也。太极拳教学中，要树立健康观，根据大学生的生理、心理和社会适应能力，依据技能动作的掌握特点和形成过程，运用电化直观教学、表象训练，多种启发等教学方法，激发、引导学生学好太极拳。  相似文献   

Dimensions: A competitor to Scopus and the Web of Science?     

Mike Thelwall 《Journal of Informetrics》2018,12(2):430-435

Dimensions is a partly free scholarly database launched by Digital Science in January 2018. Dimensions includes journal articles and citation counts, making it a potential new source of impact data. This article explores the value of Dimensions from an impact assessment perspective with an examination of Food Science research 2008–2018 and a random sample of 10,000 Scopus articles from 2012. The results include high correlations between citation counts from Scopus and Dimensions (0.96 by narrow field in 2012) as well as similar average counts. Almost all Scopus articles with DOIs were found in Dimensions (97% in 2012). Thus, the scholarly database component of Dimensions seems to be a plausible alternative to Scopus and the Web of Science for general citation analyses and for citation data in support of some types of research evaluations.  相似文献   

Do the physical and environment PETTLEP elements predict sport imagery ability?     

Nurwina Anuar  Sarah E. Williams  Jennifer Cumming 《European Journal of Sport Science》2017,17(10):1319-1327

The present study aimed to examine whether physical and environment elements of PETTLEP imagery relate to the ability to image five types of sport imagery (i.e. skill, strategy, goal, affect and mastery). Two hundred and ninety participants (152 males, 148 females; M_age?=?20.24 years, SD?=?4.36) from various sports completed the Sport Imagery Ability Questionnaire (SIAQ), and a set of items designed specifically for the study to assess how frequently participants incorporate physical (e.g. ‘I make small movements or gestures during the imagery’) and environment (e.g. ‘I image in the real training/competition environment’) elements of PETTLEP imagery. Structural equation modelling tested a hypothesised model in which imagery priming (i.e. the best fitting physical and environment elements) significantly and positively predicted imagery ability of the different imagery types (skill, β?=?0.38; strategy, β?=?0.23; goal, β?=?0.21; affect, β?=?0.25; mastery, β?=?0.22). The model was a good fit to the data: χ² (174)?=?263.87, p?<?.001, CFI?=?.96, TLI?=?.95, SRMR?=?.09, RMSEA?=?0.05 (90% CI?=?0.03–0.05). Findings displayed that priming imagery with physical and environment elements is associated with better skill, strategy, goal, affect and mastery imagery ability. The findings extend models of imagery use by indicating that how athletes images may influence their imagery ability.  相似文献   

和谐GDP论纲——一个关于GDP的和谐构想     

刘长明 《山东教育学院学报》2011,26(2):23-29

GDP本来是一个表征财富的普通符号,然而,一个时期以来,作为财富象征符号的GDP却成了人们竞相追逐并加以炫耀的对象,甚至成为国家的最高目标。于是,作为人们崇拜对象的GDP反过来异化为人们的主宰,步入一条反和谐的不归之路。在内建和谐社会、外促和谐世界的大背景下,在失衡之路上狂奔的GDP必须回归和谐,确立新的和谐GDP理念。和谐哲学为和谐GDP提供了理论可能性,而和谐社会建构实践的展开为和谐GDP奠定了坚实的推广基础。作为和谐GDP三个维度的和谐产出、和谐分配与和谐消费,彰显了GDP的和谐向度。和谐GDP的“三和”之维．有利于营造出和谐心态、和谐世态与和谐生态,使和谐GDP客观上成为和谐社会的理想经济形态。  相似文献   

Big and open linked data analytics ecosystem: Theoretical background and essential elements   总被引：1，自引：0，他引：1  

Martin Lnenicka  Jitka Komarkova 《Government Information Quarterly》2019,36(1):129-144

Big and open linked data are often mentioned together because storing, processing, and publishing large amounts of these data play an increasingly important role in today's society. However, although this topic is described from the political, economic, and social points of view, a technical dimension, which is represented by big data analytics, is insufficient. The aim of this review article was to provide a theoretical background of big and open linked data analytics ecosystem and its essential elements. First, the key terms were introduced including related dimensions. Then, the key lifecycle phases were defined and involved stakeholders were identified. Finally, a conceptual framework was proposed. In contrast to previous research, the new ecosystem is formed by interactions of stakeholders in the following dimensions and their sub-dimensions: transparency, engagement, legal, technical, social, and economic. These relationships are characterized by the most important requisites and public policy choices affecting the data analytics ecosystem together with the key phases and activities of the data analytics lifecycle. The findings should contribute to relevant initiatives, strategies, and policies and their effective implementation.  相似文献   

论“我们”散文诗意象化特征的审美建构     

张立华 《承德师专学报》2015,(3)

“我们”散文诗丛对当代散文诗的发展具有重要的价值,其诗学理念和实践将散文诗的建设推到了更高的层次,在这套丛书中散文诗的意象化特征非常明显,对散文诗审美理想的追求具有建构的功能。而意象是散文诗诗性的最直接体现,其意象原型主要有自然生态、地域家园、现代情绪等三种,这三种意象原型分别代表了不同的意象主题,在不同诗人的具体创作中有不同程度的表现。诗人们运用意象表现其情感体验,充分利用了意象的审美功能,意象组合的审美合力,完成了意象表现的最高境界,即意境的审美交融,对于意象建构下的美学理想的追求具有重要的意义,也是对“我们”散文诗群提倡的“意义化写作”的贯彻。  相似文献   

基于混沌和分维的盲水印算法     

张健  刘琳  付勇智 《人天科学研究》2014,(2):63-66

把分形维数理论应用到数字水印中,提出了基于Chebysher混沌置乱和分形维数的自适应数字图像水印算法。首先将载体图像分块,计算每个小块的分形维数。然后将载体图像进行分块DCT变换,使用改进的邻域平均法,将经过混沌置乱后的水印信息嵌入到图像的DCT域中,并根据该小块的分形维数调节嵌入强度,实现了水印信息的自适应嵌入。提取水印时,实现了完全盲提取。MATLAB仿真结果表明,该算法具有较好的不可见性,对常见的图像处理攻击具有较好的鲁棒性。  相似文献   

禅诗审美境界论   总被引：6，自引：1，他引：5  

吴言生 《陕西师范大学学报(哲学社会科学版)》2000,29(1):61-67

禅宗诗歌表达独特的禅悟体验，其审美境界的范型是一切现成现量境、水月相忘如如境、珠光交映圆融境、任运随缘日用境。现量境羚羊挂角，无迹可求；如如境能所双亡，色相俱泯；圆融境珠光交映，重重无尽；日用境饥餐困眠，脱落身心。体证禅诗审美境界，对建构21世纪中国禅诗研究学、整合传统诗学的境界论有着重要的现实意义。  相似文献   

夸父逐日神话:通向乐园的苦难征程     

王先灿 《临沧师范高等专科学校学报》2011,(3)

夸父逐日最早见于《山海经》与《列子》中的相关记载。对夸父逐日的相关研究得出两个结论,一个结论认为夸父逐日不是神话,另一个结论与之相反,认为夸父逐日是神话。文章厘清两个结论内部的各种代表观点,并认为夸父逐日是神话,在此基础上提出新的观点,即夸父逐日神话蕴含西方意象,夸父逐日隐喻东方人的乐园情结,夸父向西逐日是求索幸福与价值,夸父逐日神话表征东方民族通向乐园的苦难征程。  相似文献
