Superior short-term learning effect of visual and sensory organisation ability when sensory information is unreliable in adolescent rhythmic gymnasts

Rhythmic gymnasts specialise in dynamic balance under sensory conditions of numerous somatosensory, visual, and vestibular stimulations. This study investigated whether adolescent rhythmic gymnasts are superior to peers in Sensory Organisation test (SOT) performance, which quantifies the ability to maintain standing balance in six sensory conditions, and explored whether they plateaued faster during familiarisation with the SOT. Three and six sessions of SOTs were administered to 15 female rhythmic gymnasts (15.0 ± 1.8 years) and matched peers (15.1 ± 2.1 years), respectively. The gymnasts were superior to their peers in terms of fitness measures, and their performance was better in the SOT equilibrium score when visual information was unreliable. The SOT learning effects were shown in more challenging sensory conditions between Sessions 1 and 2 and were equivalent in both groups; however, over time, the gymnasts gained marginally significant better visual ability and relied less on visual sense when unreliable. In conclusion, adolescent rhythmic gymnasts have generally the same sensory organisation ability and learning rates as their peers. However, when visual information is unreliable, they have superior sensory organisation ability and learn faster to rely less on visual sense.     

优秀沙排运动员薛晨肩关节脱臼的运动功能康复训练效果分析

摘要：目的：通过对我国优秀沙滩排球运动员薛晨肩关节脱臼术案例进行分析,探索优秀运动员备战奥运会期间从手术后到重返训练场间的身体运动功能康复训练安排。方法：借鉴重返赛场训练的方法手段,从康复医学、体能训练和运动表现等多学科角度设计有针对性的康复训练方法。通过对比训练前后关节活动度、肌肉力量、功能动作筛查结果以及下肢力量爆发力测试结果检验以优秀沙滩排球运动员肩关节脱臼为个案分析重返赛场的可行性训练策略。结果：通过10周身体运动功能训练,运动员下肢爆发力、损伤侧肩关节内外旋活动度、均有所增加。功能动作筛查分数降低。但损伤侧肩关节内旋肌力、腹侧核心耐力有所下降。结论：以优秀沙滩排球运动员肩关节脱臼重返赛场的训练策略为个案分析,探索从运动损伤术后至重返赛场训练过程的周期安排、训练方法的有效性;通过科学整合康复训练、体能训练和专项技术训练不同训练内容,循序渐进的帮助运动员恢复专项技术和运动能力。     

马克思主义政治经济学经济发展方式理论的演进与创新

随着时代变迁和背景转换,马克思主义政治经济学自诞生以来不断得到丰富和发展,但其根本原则和核心内容仍然是生产关系演进与生产力发展的自觉统一;在其指导下的经济发展方式理论也在社会经济实践的推动下,经历了传统社会主义政治经济学和中国特色社会主义政治经济学的创新和发展.中国特色社会主义政治经济学与经济发展方式理论之间紧密联系、互相促进,其创新发展必须根植于新常态下中国经济发展的伟大实践中.

Cross-cultural influence on communication effectiveness and user interface design

The objective of this study was to investigate the impact of cultural diversity on communication effectiveness with different communication styles and to apply the results in the field of user interface design for computer-based communication systems. The scope of this study was limited to the relationship between context and verbal/nonverbal communication, and also the relationship between power distance and communication interaction. The results indicated that high context people (HCP) had better communication effectiveness in comprehending nonverbal clues than low context people (LCP), while LCP had better communication effectiveness in verbal communication than their counterparts. It was also found that high power distance people (HPDP) could not communicate as effectively as low power distance people (LPDP) during communication with interaction, but there was no significant difference between HPDP and LPDP in dealing with communication without interaction.     

作為物質文化的"中國現代文學"

作為學者,在公開場合發表演講有兩種策略,一是"小題大做",一是"大題小做".這有點像寫論文,必須先設定讀者:面對公眾發言,你得乾脆利落,越簡單明了越好,不能雲山霧罩,把聽眾繞糊塗了.     

The Art of Chinese Painting and Calligraphy Mounting

The history of Chinese painting and calligraphy mounting can date back to the Warring States period [475-221 BC]. This unique craftsmanship saw its heydays in theSong Dynasty [960-1279AD], thanks to the prosperous silk industry of the time. Moreover, Emperor Huizong, a great painter and calligrapher, was particularly fond of mounting, which gave rise to the development of the craftsmanship. Many master artists, like Mi Fu, Su Shi and Wang Shen, mounted artworks by themselves, brining prosperity to this traditional skill.     

Century-old Brand Offers Fresh Spring Tea

In the chill of the early spring in April, Wuyutai, a century-old tea shop served local customers of Beijing with fresh green tea picked and processed before the Pure Bright Festival. The well-picked and finely-processed green tea sold so well that it ran out of supply. Like what happened in previous years, the tea variety of Dragon Well from the West Lake is the most popular early spring tea among local customers. This tea variety is famous not for its super quality but also for its cultural richness.
