论篮球运动的文化内涵 总被引:25,自引:0,他引:25
金赛英 《北京体育大学学报》2004,27(3):309-311
体育的文化内涵是各种运动形式的本质属性的总和.体育文化的研究过程中,对篮球运动项目文化内涵的研究实为必然.通过文献资料与逻辑方法的研究表明:作为一种特殊的文化符号,篮球运动中蕴含着现代社会所崇尚的人文精神,它不仅在促进人类生理、心理健康方面发挥着积极的作用,而且具有明显的商业价值.篮球运动的文化价值在于通过运动体现个人自身价值和促进人类自身的有序生存和持续发展. 相似文献

A novel microfluidic device which consists of two stages for particle focusing and separation using a viscoelastic fluid has been developed. A circular capillary tube was used for three-dimensional particle pre-alignment before the separation process, which was inserted in a polydimethylsiloxane microchannel. Particles with diameters of 5 and 10 μm were focused at the centerline in the capillary tube, and the location of particles was initialized at the first bifurcation. Then, 5 and 10 μm particles were successfully separated in the expansion region based on size-dependent lateral migration, with ∼99% separation efficiency. The proposed device was further applied to separation of MCF-7 cells from leukocytes. Based on the cell size distribution, an approximate size cutoff for separation was determined to be 16 μm. At 200 μl/min, 94% of MCF-7 cells were separated with the purity of ∼97%. According to the trypan blue exclusion assay, high viability (∼90%) could be achieved for the separated MCF-7 cells. The use of a commercially available capillary tube enables the device to be highly versatile in dealing with particles in a wide size range by using capillary tubes with different inner diameters. 相似文献

引用是一种最主要的文本构成方式.引用的使用可以帮助写作者再现客观世界,体现文本的开放性特征.根据其在学术论文文本中出现的标记性,可以将引用分为显性引用和隐性引用,并随着标记性的递减构成一条由直接引用、转述、参考、暗示、抄袭的引用连续统.语篇组织方面,学术论文中的引用增加了学术论文的连贯性和多元性.同时,规范的引用保证了学术论文的客观性、独创性以及“避免攻击性”,从而成为学术论文写作中必不可少的一部分. 相似文献

This paper reports on a case study of an online pre-service teacher education course in a New Zealand university aimed at exploring the potential of student-generated podcasts as a form of interactive formative assessment at a distance. The study was part of a wider two-year funded project with the overall goal of documenting, developing, and disseminating effective and innovative e-learning practice. Findings from lecturer and tutor interviews, student focus group (FG) discussion, and course evaluations indicate that the podcasting task provided opportunities for the course lecturer, tutors, and students to learn and share ideas with one another. The experience empowered students to develop the skills and confidence to initiate more independent inquiry into technologies to support their pedagogical purposes. The study contributes to a better understanding of the skills, dispositions, and knowledge needed to prepare teacher candidates for teaching-learning contexts where information and communication technologies are increasingly pivotal. 相似文献

This study investigated the relationship between psychopathology and shame. Three hundred and thirty-one Secondary 2 students from Singapore participated in the study. All students completed a self-report questionnaire consisting of the Anxiety and Depression scales of the Behavior Assessment System for Children (BASC), the short version of the Aggression Questionnaire (AQ), and the Internalized Shame Scale (ISS). As predicted, students in the comorbid group at-risk for anxiety, depression and aggression, had significantly higher shame scores compared with at-risk students in all the other three single-disordered groups (anxiety-only, depression-only, or aggression-only) as well as students in the control group. Also, as expected, the control group scored significantly lower compared to all other single-disorder groups and the comorbid group. Implications of these findings with regard to comorbidity of psychopathology and its relationship to shame, classroom interventions, as well as implications pertaining to teachers' and counsellors' work with at-risk students will be discussed. 相似文献

近年来,挥发性有机化合物(VOC)的污染是继PM2.5、SO2、NOx和氟利昂后成为世界各国关注的又一焦点.现在国内外监测VOC的方法普遍固定,都是将VOC采样罐放在环保局、学校、各地环境监测站,进行常年定时监测,采样罐每次使用完毕需要及时进行彻底清洗,所以设计VOC清洗系统是有必要的.文章设计的VOC采样罐清洗系统是基于STC12C5A60S2单片机的,控制器以工业液晶显示屏方式显示温度值、压力值、清洗状态、清洗时间、清洗次数,有加热器、温度传感器、压力传感器对温度、压力进行实时采样,用户可通过按键自行设定系统参数.通过搭建实验平台,液晶显示屏实时显示各项参数,表明采样罐清洗系统是稳定可靠的. 相似文献

目的:通过分析双眼阅读条件下弱视患者的弱视眼和非弱视眼与正常人主导眼和非主导眼的眼球运动特征,探究弱视患者与正常人阅读过程眼球运动的差异性,揭示弱视患者在正常阅读状态下两眼的影响作用。方法:选取成人单眼弱视16例及屈光矫正视力正常的被试32例,采用SMI公司生产的iView High-Speed1250眼动仪,记录被试在正常双眼汉语阅读状态下左右眼各自的眼球运动数据,并运用spss对实验所得的眼动数据进行统计分析。结果:双眼阅读条件下,正常人主导眼与非主导眼之间无论是阅读速度还是其他眼动指标均无显著性差异。重度弱视患者的弱视眼与非弱视眼在阅读速度、注视点次数及注视点持续时间上均存在显著性差异;中轻度弱视患者的弱视眼与非弱视眼之间的眼动指标基本类似。其中重度弱视患者的非弱视眼与正常人主导眼之间在阅读速度、注视次数及眼跳幅度上存在显著性差别;而中轻度弱视患者的非弱视眼与正常人主导眼的阅读速度、注视时间等比较均没有显著性差异。结论:在双眼汉语阅读条件下,弱视患者的弱视眼对非弱视眼的阅读速度及眼球运动产生影响,非弱视眼的阅读速度明显比正常人慢,且注视点持续时间长。其中重度弱视患者的非弱视眼对弱视眼的抑制作用更为明显。 相似文献

ABSTRACTWhat is the place of the diasporas within the Inter-Asia Cultural Studies movement, and how can Asian diasporas in the West contribute to Inter-Asia's intellectual project of “problematising Asia”? Developing a notion of diaspora as method, this essay highlights the complementary relationship between the Asian Australian Studies Research Network and the Inter-Asia Cultural Studies network. It argues that the Inter-Asia network has much to gain from embracing the Asian Australian diaspora as an interlocutor with shared priorities and concerns, and that Asian Australian studies can also productively learn from Inter-Asia's alternative model of institutionalisation, thereby expanding its theoretical and methodological frames of reference. 相似文献
