元话语与语篇互动     

李健民 《忻州师范学院学报》2012,28(3):32-35

文章从连贯、修辞、对话和评价方面探讨元话语和语篇互动之间的关系,指出元话语运用是语篇互动的表现,是一种有效的修辞策略。元话语表示作者在所展开的语篇中定位自己和读者,并在特定的语境中构建具有说服力和连贯的语篇。在语篇中作者控制互动关系的表达方式对于修辞效果十分重要。语篇的互动表明语篇由作者与读者或受众共同构建,元话语是体现这种互动的最明显的标记,体现语篇交际的主体间性,动态性和对话性。元话语既是显性也是隐性的评价手段,但本身没有正面和负面评价之分,通常与基本话语的评价共同作用,产生赋值评价意义,并对评价具有调控作用。揭示元话语和语篇互动关系对于二语写作教学具有指导作用。  相似文献   

Using Coh-Metrix to Automatically Access Discourse Coherence in EFL Learners’Writing:A Quantitative Analysis     

李雪莲 《海外英语》2012,(17):117-120

The purpose of the present study was to use Coh-Metrix,a computational tool,to examine the relationship between discourse coherence and writing level,and analyze the coherence of high level writing and low level writing.The study uses 5 Coh-Metrix variables to analyze 40 college students’timed compositions from Chinese Learners English of Corpus(CLEC) and their corresponding readability scores.The study demonstrates that Coh-Metrix variables,number of words,words per sentences,the Flesch-Kincaid Grade Level,LSA sentence all,and argument overlap can contribute to text coherence.Findings of the study indicate:there is a relationship between discourse coherence and writing level,but there is no significant difference between high level group and low level group in discourse coherence(p=.409>.05),and writing level can not distinguish discourse coherence in EFL learners’writing.  相似文献   

阿尔茨海默症患者话语的衔接与连贯分析     

赵俊海 《楚雄师范学院学报》2012,27(10):73-80

伴随全球很多国家日益进入老龄化社会,阿尔茨海默症患者的人数呈显著增长趋势。记忆力衰退是该症的显性表征,但研究发现,阿尔茨海默症患者语言功能的退化早于记忆功能的退化,因此研究患者的语言表现对该症的早期预防及筛查无疑具有积极的意义。借助系统功能语言学的衔接与连贯理论,对30名阿尔茨海默症患者和等数健康老年人的话语作了基于衔接与连贯的分析,发现患者在话语构建方面显著低于健康老年人,集中表现为话语的整体连贯受损,同时在话语损伤方面显著高于健康老年人。表明阿尔茨海默症患者的语义记忆和工作记忆均遭受了不同程度的损伤。  相似文献

Using optical coherence tomography to characterize thick-glaze structure: Chinese Southern Song Guan glaze case study     

《文物保护研究》2013,58(2):67-75

Abstract

This study explores the structure characteristics of thick glaze, in terms of the case study of Chinese Southern Song Guan (SSG) ware, focusing on the bubble and its media structure, using a novel focus-tracking optical coherence tomography (OCT) system. The OCT images we obtained not only unveil the structural uniqueness of the thick-glaze SSG sample, but also establish a distinguishable structural pattern for aiding authentication. In addition, information revealed in our images provides a logical explanation for the subtle texture and tone of SSG glaze as well as insights into the technologies used in layering and firing these thick glazes.  相似文献   

Inclusion and mainstream education: an equal cooperation system     

S. Ebersold 《欧洲特需教育杂志》2013,28(1):89-107

By being holistic, inclusion implies the involvement of a wide variety of professionals coming from very diverse professional and institutional backgrounds. It will only find its unity in a common focus on the individual project and in the coherence of all participants' contributions, interactions and interrelationships. Because such coherent functioning is far from being spontaneous, the proposed analysis aims to identify some features contributing to the coherence of mainstream schooling situations and to the quality of the guidance of the assistant. It reveals that this coherence lies in the ability to define clearly what is expected by a mainstream education process, so that the different actors can combine an integrative perspective based on schools' needs and a participative approach based on children's needs. Secondly, it appears that guidance is likely to be appropriate to the child's needs if it is based in the coinvolvement of interindividual and organizational contractual relationships. Finally, the analysis reveals that the coherence of a mainstream education process presupposes strategies through which equal cooperation systems, taking into account inter-individual dynamics as well as organisational logics, can be created.  相似文献   

Simulation games in science education‡     

George Marx 《International Journal of Science Education》2013,35(1):31-45

The astronomy concepts of 345 young people were studied over a 10‐year period using a multi‐media, multi‐modal methodology in a research design where survey participants were interviewed three times and control subjects were interviewed twice. The purpose of the research was to search for evidence to clarify competing theories on conceptual coherence versus knowledge‐in‐pieces, distinguishing between coherence as revealed in the representational systems at any particular stage in a young person’s development and the changes evident in mental growth thereafter. Thus five research questions concerned with the elements and structure of understanding were investigated: (1) conceptual coherence shown as patterns of high correlation of concept representations between the media used to assess subjects’ understanding within a survey, as well as (2) coherence revealed as consistency of representation of those concepts across media and modalities; (3) enhanced conceptual understanding and skill through repeated interviews across (longitudinal) surveys, as young people develop their knowledge; (4) cultural similarity in subjects’ representations of basic static concepts (e.g. the shape of the Earth); and (5) improved understanding of basic dynamic concepts (e.g. the motion of the Earth) and complex dynamic concepts (e.g. seasons and eclipses), through “knowledge‐skill compounding”. The research findings supported conceptual coherence and rejected the counter argument of knowledge‐in‐pieces (at an alpha level of .05). Further research is recommended to replicate current research in cultures other than those of China and New Zealand studied here to confirm the view that cognition and knowledge are inherently coherent in young people.  相似文献

外语学习中的话语得体     

于善志 《宁波大学学报(教育科学版)》2007,29(3):90-94

文章区分了语言的系统用法和具体用法,认为话语得体既包括形式得体又包括功能得体。得体的话语有利于发展特定的语篇意义。话语以语言的系统用法为基础,在语境中通过语言的具体用法而实现其交际意义。  相似文献   

高分辨率SAR子孔径图像相干性分析 及其地物分类应用     

邢文继  金燕  仇晓兰  丁赤飚  周晓 《中国科学院大学学报》2022,39(6):764-775

针对相干性这一合成孔径雷达(SAR)图像分析常用的特征量进行分析,首先从理论上分析高分辨率SAR图像中人造目标和自然地物等典型目标的子孔径、子频带以及不同子孔径重轨干涉图像间的相干系数,然后利用高分辨率星载SAR实际数据开展上述相干系数的计算,验证分析的正确性。随后根据不同地物在不同维度相干系数上体现的不同特点,进行非监督地物分类,并给出不同类别所表征的地物特点。分析结果可为高分辨率SAR数据的优化应用提供支撑,并可加深对SAR不同地物目标特性的理解。  相似文献
