英语的时空修辞

西方语言中的时空修辞普遍存在于日常语言中，它反映出人类认知、理解和表达客观世界时所采用的直观、形象、非精确计量的思维方式和富于多方联想的思维过程。英语中时空观念的表达方式有：用空间表示时间、时空互为一体、用动物或人的寿命、活动方式来表示时空，用物体运动的方式表示时空等等。     

黄伯荣本《现代汉语》若干问题探析

黄伯荣《现代汉语》（增订二版）是多年来高校广泛采用的教材。我们在使用过程中发现该教材仍有一些美中不足之处。本文就教材（下册）关于“句型的确定”、“病句的判定及修改”、“辞格的认定及辞格的综合运用”等方面存在的问题进行分析，提出商榷意见。     

损失规避下的指数跟踪问题及其粒子群算法求解

随着指数衍生产品日益受到重视,指数化投资组合常被传统的消极基金管理者或机构所采用,而用有限的资金按指数构成比例进行投资显然是不现实的,所以指数的最优误差追踪就显得更加重要。将追踪误差定义为证券投资组合收益率与所追踪的指数基准收益率之差的均值平方和的平方根,建立了基数约束（即总资产数不超过某个特定整数K）下考虑投资者损失规避决策偏好的跟踪误差最小化模型,并设计了一个粒子群算法求解模型。实际算例表明,所构建的模型和算法是有效的。     

奥巴马修辞人格构建研究

奥巴马成为美国历史上的第一位黑人总统后,人们对于他的成功表现出浓厚的兴趣。在有着悠久修辞传统的西方世界,奥巴马也是这方面的＂高手＂。他深谙修辞之术,通过掌控各种修辞资源来达成自己的修辞意图。本文试图运用西方修辞学中的修辞人格理论来阐释其构建修辞人格,树立权威,增强言辞说服力和影响力,从而赢取选民获得胜利的过程。     

基于汉语的时间推进分析框架

时间推进是语篇发展的基本原则,是语篇连贯的重要手段。但是关于哪些因素影响了时间推进,如何分析时间推进,目前并没有形成一个很好的分析框架。本文采用修辞结构理论,以汉语为分析材料,再现了时间推进和语篇结构的关系,区分出三个层面的时间推进,提出了一个时间推进分析框架。这一分析框架的建立对于第二语言的写作教学具有应用价值。     

从伯克的"语言四维度"看"印象系列"的修辞效果

在<语言是象征行动>中,伯克明确提出语言四个基本维度:诗学、逻辑与语法、修辞以及伦理学.这四个维度几乎覆盖了语言的所有范围:诗学语言在富有情感的同时也含有理性的成分;逻辑语言并不仅仅局限于语法及逻辑思维,更应与理性相结合,指导行动;修辞语言贵在用劝说、劝勉的语气达到合作竞争的目的;伦理语言,要求我们真实准确地表达人格品...     

A rule induction framework for the determination of representative learning design in skilled performance

Representative learning design provides a framework for the extent to which practice simulates key elements of a performance setting. Improving both the measurement and analysis of representative learning design would allow for the refinement of sports training environments that seek to replicate competition conditions and provide additional context to the evaluation of athlete performance. Using rule induction, this study aimed to develop working models for the determination of high frequency, representative events in Australian Rules football kicking. A sample of 9005 kicks from the 2015 Australian Football League season were categorised and analysed according to the following constraints: type of pressure, kick distance, possession source, time in possession, velocity and kick target. The Apriori algorithm was used to develop two models. The first consisted of 10 rules containing the most commonly occurring constraint sets occurring during the kick in AF, with support values ranging from 0.15 to 0.22. None of the rules contained more than three constraints and confidence values ranged from 0.63 to 0.84. The second model considered ineffective and effective kick outcomes and displayed 70% classification accuracy. This research provides a measurement approach to determine the degree of representativeness of sports practice and is directly applicable to various team sports.     

Preparation time influences ankle and knee joint control during dynamic change of direction movements

The influence of preparation time on ankle joint biomechanics during highly dynamic movements is largely unknown. The aim of this study was to evaluate the impact of limited preparation time on ankle joint loading during highly dynamic run-and-cut movements. Thirteen male basketball players performed 45°-sidestep-cutting and 180°-turning manoeuvres in reaction to light signals which appeared during the approach run. Both movements were executed under (1) an easy condition, in which the light signal appeared very early, (2) a medium condition and (3) a hard condition with very little time to prepare the movements. Maximum ankle inversion angles, moments and velocities during ground contact, as well as EMG signals of three lower extremity muscles, were analysed. In 180°-turning movements, reduced preparation time led to significantly increased maximum ankle inversion velocities. Muscular activation levels, however, did not change. Increased inversion velocities, without accompanying changes in muscular activation, may have the potential to destabilise the ankle joint when less preparation time is available. This may result in a higher injury risk during turning movements and should therefore be considered in ankle injury research and the aetiology of ankle sprains.     

庄子摆脱社会之困的方法论探讨及其生态解读

庄子认为,人的一生都面临着命运、社会、自我以及环境等因素带来的难以摆脱的困境。其中,社会之困主要是指时势、儒家仁义等对人的限制或束缚。庄子对时势之困采取了安时处顺、无为而治的消解方法,对仁义之困采取了法天贵真、掊击圣人、以道释儒的化解策略。在庄子所采取的摆脱社会困境的种种策略和方法中所贯穿的都是顺物自然的生态学原则。     

上海市公共体育设施建设效应评价研究

上海市公共体育设施建设的主要矛盾是市民日益增长的多元化体育需求和公共体育设施建设不平衡、不充分发展之间的矛盾。作为迈向卓越的全球城市，上海正为向市民提供多元化需求的公共体育设施而努力。本文根据“30分钟体育生活圈”的要求，对上海市公共体育设施建设效应进行研判，得出：（1）上海市公共体育设施布局呈现等级性，空间上呈现“中心-外围”特征，形成了“市-区-街道”三级空间尺度的公共体育设施空间布局。（2）上海市公共体育设施空间布局与人口密度分布呈正相关关系。健身点密度、市民球场、市民健身房、市民健身步道与人口密度分布呈现较强的正相关关系；农民健身工程与人口密度分布呈现较强的负相关关系。（3）上海市公共体育设施密度区域差异显著。公共体育设施建设正处于数量增加向质量提升的过渡阶段，正建设与卓越的全球城市和社会主义国际化大都市相匹配的公共体育设施与配套服务。（4）上海市公共体育设施建设总体评价较好，但存在难以满足多元化需求等问题。调查显示，居民对上海市公共体育设施建设的总体评价较好，满意度评价较高，但未满足个性化、多元化需求，在软件环境建设上仍有很大提升空间。
