竞技健美操女子单人项目难度动作发展趋势研究

对第9届世界健美操锦标赛女单前3名运动员成套动作中难度动作的编排、类别、完成率以及根命名进行分析研究,结果表明：（1）世锦赛优秀女单运动员在难度动作编排分值、难度类别、完成率及根命名上一致性程度较高;大部分难度集中在0．5～O．7之间,高分值（≥0．8）难度已演变为优秀运动员难度分值提高的着眼点;难度动作以C类组别为主,均衡发展体能各子因素是运动员难度动作合理化的关键所在;高难度动作的掌握不够稳定,运动员专项体能有待加强;动作根命名较为集中,针对性体能训练已成为个性化难度发展的突破口;（2）优化运动员体能结构,使各体能因子能够达到最佳匹配是难度动作得以全面发展的关键。     

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

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.     

Do EFL Teachers ‘Critically’ Engage in Cultural Awareness? A Mixed-Method Investigation

ABSTRACT

This study explored 150 EFL teachers’ perceptions of critical cultural awareness (CCA) considering their teaching context, academic degree, and professional development programs. The participants all completed the CCA questionnaire, fifteen of whom also sat a semi-structured qualitative interview. Our findings showed, a) EFL teachers’ perceptions of CCA located at a medium level, b) the PhD participants showed significantly higher engagement in CCA than their BA and MA counterparts, c) private language institute teachers reported higher levels of CCA than their state-run school counterparts and d) local professional development programs did not emphasize culture teaching in general and CCA in particular.

Potential for transformation? Two teacher training programs examined through a critical pedagogy framework

This paper argues that teacher training programs, with the objective of transforming gender norms in schools, should employ a critical pedagogy framework in order to achieve the transformational learning goals necessary to change the deep-seated beliefs and patterns of behavior that characterize these gender norms. Using document analysis, this study evaluates the teacher in-service training component of two school-based intervention programs, aimed at promoting gender equality in school communities. This paper finds that the trainings miss opportunities to employ elements of critical pedagogy and therefore, are not likely to create a transformative change around gender norms in schooling.

英汉实词附着化对比分析——助动缩略形式“＇Ⅱ”与复数标记“们”

附着化是一个实词演化为附着形式的过程，英语的助动缩略形式“Ⅱ”和汉语复数标记“们”都是由实词逐渐虚化为附着成分的。论文尝试运用语法化的理论，解释“＇Ⅱ”在句法形态层面上引起的“不一致”现象和“们”的“语法词缀”说所遇到的困难，通过对比影响二者附着化的相关因素来分析各自的语法化特点和发展方向。
