F_(μ0)映射的Ky Fan匹配定理及其对抽象经济的应用

利用KKM技巧建立了FC-度量空间中凡。映射的Ky Fan匹配定理,作为应用,获得了FC-度量空间中的Ky Fan重合定理、定性对策和抽象经济的平衡存在定理。我们的结论统一、改进和推广了一些近期文献的已知结果。     

杰克逊·波洛克对美国20世纪美术的影响

作为二战后出现的一种绘画流派,抽象表现主义对美国艺术乃至整个西方艺术在20世纪的发展产生了难以忽视的影响。作为抽象表现主义的中流砥柱以及美国20世纪艺术的代表人物之一．杰克逊·波洛克以其独特的美学观点与创作手法在西方艺术史上留下了极富个人特色的一笔。     

Individual differences in the effect of relevant concreteness on learning and transfer of a mathematical concept

The concreteness of training materials influences learning and—perhaps more importantly—transfer. Building on prior research finding abstract representations best facilitated transfer to a game task, we conducted a similar study using training figures varying in concreteness but directly assessed transfer to modular arithmetic problems. Training figures: (a) were purely abstract, (b) were abstract but with features relevant to the transfer task, or (c) included additional concrete-relevant features. We hypothesized that concreteness—or number of relevant features—would be positively correlated with learning and transfer—especially among younger and/or lower-ability students. Although there was no overall difference in initial learning, the concrete-relevant and abstract-relevant features independently facilitated near-transfer, where concrete-relevant features supported lower-reasoning students. For far-transfer, eighth-graders benefited from the abstract-relevant features, whereas sixth-graders required additional concrete-relevant features. These findings suggest that concreteness interacts with learner and task characteristics to produce learning and transfer outcomes.     

Conversational themes and attention focusing strategies: Predicting comprehension and recall

The specific purpose of this study was to examine the effects of conversational themes and attention focusing strategies on conversational comprehension and recall. A 2×2×2×2 between subjects factorial designs was used to test the research question with 247 participants. The results demonstrated that the unambiguous themes predicted conversational comprehensibility and recall accuracy. The results indicated that personal conversational information may be processed differently from content conversational information. Future conversational processing research should focus on discovering the reasons for the processing differences between content and personal conversational information.     

图式、理解与阅读

心理语言学认为图式是语义记忆网络中的一种信息贮存结构.在语言理解和记忆中的作用是根据已知信息对新信息进行加工.阅读是为了汲取新知识,获得新信息.在阅读过程中读者大脑中已有的语言图式、内容图式和形式图式与文章中信息的相互作用决定了读者对文章的理解程度,是影响阅读理解的主要因素.采用相应阅读策略进行训练,可提高阅读力.读者语义记忆中的图式越多越完善,阅读效率就越高.     

基于本体的图书馆文献资源共享技术研究

图书馆文献资源共享是图书馆发展的一个重要标志,为了实现文献的共享和重用,解决图书馆文献资源检索中语义信息表达问题,将本体思想引入文献信息知识表示中。提出了图书文献资源本体概念的结构层次和体现形式,构造了OIL描述的图书馆文献资源知识本体,给出了用XML Schema实现OIL描述的资源知识本体的方法。     

一种可并行逆向工程处理的设计模式

建立一种可并行逆向工程处理的抽象机设计模式,并通过测试说明使用该模式可以减少处理时间。     

信息集成:基于XML Schema的模式匹配

XML Schema在信息集成中的应用,是近年来的研究热点。本文从模式匹配的角度,构造了XML Schema的语义模型,然后利用相似度和宽松标识来测量模式之间的匹配程度,以提高匹配的准确度。     

从图式阅读理论看阅前准备的必要性

以Rumburt 的图式阅读理论为依据, 从背景知识(语言、内容、形式) 与阅读理解之间相互作用的内在联系入手, 在外语阅读教学中, 做好学生的阅前准备, 激活(stimulate) 学生已有的背景知识, 是不容忽视的一个教学环节。
