从量词“堆”与“叠”的形成演变看其用法差异     

麦宇红 《阜阳师范学院学报(社会科学版)》2003,(3):38-39

量词经历了一个复杂的演变过程,因其意义源于造字之初的名词或动词,所以量词的语义特征、语用及其修辞都不可避免地带有原初形式的烙印。文章论述了近义量词"堆"与"叠"的演变轨迹、自身所带有的语义特征;并在对语言材料进行归纳分析的基础上指出两者的差异。  相似文献   

Culturally appropriate face strategies in cooperative learning with insight from cultural neuroscience     

Mai Nguyen-Phuong-Mai 《比较教育学》2019,55(1):66-96

ABSTRACT

Face, understood as public image, exerts critical influence on interpersonal communication. Incorporating insight from cultural neuroscience, a number of potential mismatches with regard to facework are revealed when methodologies originated from the West are applied in a different context. This paper examines culturally appropriate face strategies in cooperative learning among Vietnamese learners. Our results show that discussion outcomes increase when self-face and other-face are confirmed and group-face is mildly confronted in form of intergroup competition. The paper indicates that educational methods underpinned by fundamental psychological assumptions based on Western values should be adjusted to be culturally appropriate for contexts in which it is applied.  相似文献

Response of brain-derived neurotrophic factor to combining cognitive and physical exercise

Purpose: Brain-derived neurotrophic factor (BDNF) is well known for its potential to promote brain plasticity. It has been proposed that combining cognitive and physical exercise (CCPE) may have the potential to generate more synergistic benefits in cognitive function than either cognitive exercise (CE) or physical exercise (PE) alone. The purpose of this study was to examine acute responses of peripheral BDNF levels and cognitive performance to CE, PE, and CCPE.

Methods: Thirteen healthy adult men participated in four experimental sessions; a 30-min CE, a 30-min cycling PE at an intensity of 60% peak oxygen uptake, a 30-min CCPE at the same intensity as PE, and a 30-min session of complete rest. Plasma BDNF levels and cognitive performance were measured before and after each session.

Results: Both PE and CCPE significantly increased plasma BDNF levels (p?p?≥?.05), and there was no significant difference in peripheral BDNF levels between PE and CCPE (p?≥?.05). No session induced a significant change in cognitive performance (p?≥?.05).

Conclusions: Our study suggests that CE and PE have different responses of peripheral BDNF levels and that CCPE had no additional or synergistic effect on peripheral BDNF levels compared with PE alone. This study offers further insights into the potential mechanisms underlying the respective roles of CE, PE, and CCPE for peripheral BDNF levels and cognitive performance.  相似文献   

Inducing self-rotation of cells with natural and artificial melanin in a linearly polarized alternating current electric field     

Mengxing Ouyang  Wing Ki Cheung  Wenfeng Liang  John D. Mai  Wing Keung Liu  Wen Jung Li 《Biomicrofluidics》2013,7(5)

The phenomenon of self-rotation observed in naturally and artificially pigmented cells under an applied linearly polarized alternating current (non-rotating) electrical field has been investigated. The repeatable and controllable rotation speeds of the cells were quantified and their dependence on dielectrophoretic parameters such as frequency, voltage, and waveform was studied. Moreover, the rotation behavior of the pigmented cells with different melanin content was compared to quantify the correlation between self-rotation and the presence of melanin. Most importantly, macrophages, which did not originally rotate in the applied non-rotating electric field, began to exhibit self-rotation that was very similar to that of the pigmented cells, after ingesting foreign particles (e.g., synthetic melanin or latex beads). We envision the discovery presented in this paper will enable the development of a rapid, non-intrusive, and automated process to obtain the electrical conductivities and permittivities of cellular membrane and cytoplasm in the near future.  相似文献

麦春苗 《科教文汇》2013,(5):204-205

在国际金融危机席卷全球的背景下,广东省政府于2009年2月21日发布《关于试行广东省国民旅游休闲计划的若干意见》,率先试行国民休闲计划,旨在扩大居民消费需求、最大限度调动群众参与休闲活动的积极性。在过去的四年时间里,各大旅游企业陆续将国民休闲计划付诸实践,学界的相关研究也愈发深入。本文在综述学界对国民休闲计划研究现状的基础上,指出现有研究成果达成的共识和存在的不足;然后选取广东长隆集团作为旅游企业的代表,具体分析其在国民休闲计划下的发展情况并提出应对措施;最后,总结国民休闲计划对旅游企业的影响。  相似文献   

男子沙滩手球射门方式分析     

单宇  麦粤徽  罗金满 《安徽体育科技》2013,34(1):26-28

采用文献资料调研、数理统计法和专家访谈等方法,对2011年欧洲男子沙滩手球锦标赛与2010年、2008年世界男子沙滩手球锦标赛共计174场比赛数据进行分析,结果显示:1)SPS是最常用的射门方式,其次是SPE和INF;2)在Shoot out决胜中,各队都运用较多的SPS来赢得比赛。据此,男子沙滩手球运动训练应加强SPS和INF的训练;重点培训守门员的攻击能力;进行各种角度的空中接力射门配合;巩固中路进攻的同时,提高2个边路的得分能力。  相似文献   

部首刍议     

王麦巧 《渭南师范学院学报》2001,16(6):33-35

部首主要用于给汉字分类，从古至今，部首经历了三个发展阶段，由《说文解字》至《字汇》为第一阶段，这一时期的部首主要指出汉字的意义所属，凡是属于同一意义范畴的字归在同一部首；由《字汇》至《康熙字典》为第二阶段，这一时期的部首既重视表意。又注意到表形，凡是属于同一意义范畴的字，形体偏旁相同的排列在一起；由《康熙字典》至今为第三个阶段，这一时期的部首偏重汉字的形体，主要是为了人们检字方便，只要是具有共同形体偏旁的字即使不属同一意义范畴也归在同一部首。  相似文献
