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.     

一个带协变量调整多响应比较的高效方法及其在基因组数据中的应用

目前在文献中有很多关于多响应比较的研究方法,但是对带协变量调整的非参数检验的研究较少。一种直观的想法是将数据先投影到协变量的正交空间中,然后再利用秩和检验、调整的秩和检验或最大值检验方法。但是,功效普遍不高。在调整的秩和检验和伪F检验两种方法基础上,构建MIN2检验。大量模拟和实际数据表明,MIN2检验的效果优于现有的非参数检验方法。     

铝基复合材料烧结试验中试样制备及试验方法研究

铝基复合材料烧结试验所用试样的制备方法采用常用的粉末冶金法,它的制备方法包括粉末预处理,配料,混料,冷压成形,制样等.但每一个工序都与传统的粉末冶金法有所不同,具有其独特性.原位观察法进行烧结试验也为课题组独创.这些研究为铝基复合材料烧结工艺研究提供了试验依据.     

服务行政与政府服务力探析

服务型政府是市场逻辑的必然要求。从20世纪80年代以来,西方各主要国家相继开始了大规模的政府再造运动,以建立企业型服务政府。政府角色的嬗变,体现了行政实践模式和行政观念的彻底转型。当前,我国已经初步实现了政府角色和职能的转变,确立了服务行政的雏形,并正向纵深发展。政府在步入服务角色之后,如何提升政府服务力成为构建服务型政府的关键。政府服务力既包括政府部门的外显行为,也包括公民对政府行为在心理上的内隐反应。作为一个有机整体,政府服务力指标可以使政府服务力得到全面、系统、科学的反映。有效地实现服务行政,政府确立并践行服务理念固然重要,但同时还需要注意政府角色的梳理和调适,注意政府工作人员的角色领悟和角色表演。只有从质和量多个维度上提升政府服务力,才能在深层次上提高服务行政的水平。     

论宋代尚祥之风

宋时上自皇帝,下至普通百姓普遍崇尚祥瑞,这种风气的形成有着特殊的社会根源.尚祥之风对宋时政治、经济、社会乃至军事都产生了较为深刻的影响.其中,"天书事件"将对祥瑞的崇奉推向了顶峰.近年来,宋史研究取得了较丰富的成果,但在宋代神秘文化方面的研究一直较为薄弱,除少数几个学者在宋代巫术、占卜方面有所论述外,其他内容少有涉猎.     

从语言游戏到符号的圆舞——基于实践信息论的当代西方哲学批判

当代西方哲学的生活理性转向,使作为生活的"活"的形式的语言成为研究的焦点.但是,生活一般的超时代、超现实的抽象性,使它无法解释语言与现实的关系.真正现实地诠释语言,需要超越生活哲学的大实践观和大理性观,需要实现理性形式与现实实践的彻底贯通.在这里,当代西方哲学停滞不前,并在生活哲学本身所蕴涵的抽象解构维度中,将语言无根化和相对化,甚至进一步将其抽象为符号.这种符号化,在西方发达社会,已超越文化的樊篱而向社会生活一切领域蔓延.实践与理性的全面、全息性质以及信息倍增的超循环互动特征,因这种符号化而被异化,并被模仿化、幻象化(simulacrum)、碎片化、即时化等符号化表象所掩盖.

Pre-service teachers' implicit and explicit beliefs about English language learners: An implicit association test study

Pre-service teachers' attitudes and beliefs about English Learners (ELs) are especially critical as they enter their professions among an increasingly diverse student population. This study uses an Implicit Association Test to explore implicit and explicit beliefs and attitudes of pre-service teachers about ELs. Pre-service teachers from a Southeastern U.S. university hold generally positive implicit beliefs about ELs and express positive expectations for working with ELs and school support. Implicit association test measures have potential as tools for preparing pre-service teachers and evaluating the impact of interventions that seek to improve teachers’ readiness to serve this population.     

Difference score reliabilities within the RIAS-2 and WISC-V

Many prominent intelligence tests (e.g., Wechsler Intelligence Scale for Children, Fifth Edition [WISC-V] and Reynolds Intellectual Abilities Scale, Second Edition [RIAS-2]) offer methods for computing subtest- and composite-level difference scores. This study uses data provided in the technical manual of the WISC-V and RIAS-2 to calculate reliability coefficients for difference scores. Subtest-level difference score reliabilities range from 0.59 to 0.99 for the RIAS-2 and from 0.53 to 0.87 for the WISC-V. Composite-level difference score reliabilities generally range from 0.23 to 0.95 for the RIAS-2 and from 0.36 to 0.87 for the WISC-V. Emphasis is placed on comparisons recommended by test publishers and a discussion of minimum requirements for interpretation of differences scores is provided.
