IQ vs phonological recoding skill in explaining differences between poor readers and normal readers in word recognition: Evidence from a naming task     

López  Mercedes Rodrigo  González  Juan E. Jiménez 《Reading and writing》2000,12(1-2):129-142

The aim of this study was to investigate whether differences inreading performance between poor readers and normal readers could bebetter explained by phonological recoding deficiences than IQ. A sampleof 132 Spanish children was classified into four groups according to IQ(<80; 81--90; 91--109; 110--140) and into two groups based on readingskills (poor readers vs normal readers). A word naming task was alsoadministered. We manipulated the word parameters (length, positionalsyllable frequency, and word frequency) and nonword parameters (lengthand positional syllable frequency) to find out whether students withreading disabilities would have more difficulties than normal readers innaming words under conditions that require extensive phonologicalcomputation. The results demonstrated that there were differencesbetween Spanish children who were normal readers and those who were poorreaders, independent of their IQs.  相似文献   

Prefixes as access units in visual word recognition: A comparison of Italian and Dutch data     

Assink  Egbert M.H.  Vooijs  Caroline  Knuijt  Paul P.N.A. 《Reading and writing》2000,12(3):149-168

Two experiments were conducted to compare morphological processing of skilled and less skilled Dutch readers. Prefixes and suffixes provide morphological information concerning meaning and/or function of the word stem. There is some empirical support for the hypothesis that these sublexical access units are functionally involved in the process of word recognition. The present study focuses on the role of prefixes as access units in visual word recognition. Adult skilled Dutch readers and elementary school children were presented a lexical decision task using polysyllabic word and nonword items. Prefix Frequency (high/low) and Prefix Quality (true/pseudo prefix ratio) were manipulated. Evidence for differential use of prefix information in adults and elementary school children was found. Characteristic difference patterns between skilled and less skilled readers are discussed. It is concluded that the information accessed by prefixes is semantically combined with the subsequent word stem (root). Characteristics of the prefix plus stem combination largely determine speed of access to the complex word item processed.  相似文献

体育免费师范生职业认同与工作满意度的 关系研究          下载免费PDF全文

曾紫荣 《河北体育学院学报》2016,30(5):67-72

对95名已毕业的体育免费师范生进行访谈和调查,研究体育免费师范生的职业认同和工作满意度及其相互关系.结果表明:体育免费师范生对职业的认同度总体来说较高,四个因子中职业价值观认同度最高,角色价值观认同度最低;体育免费师范生对工作的满意度不高,主要由工作强度和工资收入导致;体育免费师范生的教师职业认同与工作满意度之间呈显著正相关,并且工作满意度能够被职业认同预测,其中预测力最高的是角色价值观.建议提高体育免费师范生的角色价值观,改革体育免费师范生培养方案,并尝试使用激励手段,不断提高体育免费师范生的职业认同和工作满意度.  相似文献   

Finding a voice,fighting for rights: the emergence of the transgender movement in Hong Kong 1     

Robyn Emerton 《Inter-Asia Cultural Studies》2013,14(2):243-269

Abstract

This paper is intended to provide a space for reflection on Hong Kong’s transgender movement at its current stage, with particular reference to the objectives and activities of the Hong Kong Transgender Equality and Acceptance Movement (‘TEAM’). Established in 2002, TEAM was the first organized group of transgender people and supporters in Hong Kong. First, the paper examines the emergence of the transgender movement in Hong Kong, situating the stated objectives of TEAM in the broader social, legal and political context in Hong Kong. It then considers the successes and limitations of TEAM’s activities to date, measured against its objectives. Finally, it examines why Hong Kong’s transgender community has not yet fought for the right to legal recognition of their gender identity, as have transgender individuals and transgender movements in many other countries around the world. In the Asia‐Pacific region these include Australia, Japan, the People’s Republic of China, the Philippines, Singapore, South Korea and New Zealand. Through interviews with members of TEAM, the paper questions whether legal recognition is indeed a concern and/or priority for Hong Kong’s transgender community, and, if so, what prevents Hong Kong transgender people from claiming their right to legal recognition in the courts or through the political process.  相似文献   

基于熵的支持矩阵机     

朱昌明 《上海海事大学学报》2016,37(4):92-100

针对支持向量机(Support Vector Machine,SVM)无法处理不平衡和矩阵模式等问题,以支持矩阵机（Support Matrix Machine,SMM）为基础,提出一个基于熵的SMM （Entropy based SMM, ESMM）来解决不平衡数据集.ESMM的贡献是：(1)提出了一个新的基于熵的模糊隶属度评价方法从而增强确定模式的重要性;(2)保证了正类模式的重要性并且得到一个更加灵活的决策面.在真实世界的不平衡数据集和矩阵模式上的实验表明,ESMM比那些与之相比较的学习机有更好的性能.  相似文献   

医易科学体质学说应用于运动员早期选材及气质认定方法的研究     

来德淳 《吉林体育学院学报》2008,24(4):86-88

通过早期选材的方式使运动训练过程更具有针对性,更快地培养出符合专项体能、技能和心理素质要求的运动员,是竞技体育科学化发展的必然趋势。为了寻求最佳选材途径和方法,此研究以专项运动员应具备特定气质为研究视角,以传统医易科学体质学说为依据,结合当今其它气质理论的研究成果,对运动员气质类型认定方法等问题进行了深入探索。在此基础上,对辽宁省射击项目上取得优异成绩的部分运动员进行了气质类型分析。结果显示,医易科学体质分类方法在运动员早期选材上的应用价值主要在于：能科学地解释不同气质个体在生理机能、身体形态、心理特征、运动能力等方面差异存在的客观性和必然性,使早期选拔具有专项潜能的运动员进行针对性训练成为可能。其中,研究中首次提出的“黄氏五分六项气质认定法”,是目前国内外唯一的早期选材气质综合性认定的方法,此法不仅可以应用于运动类型和专项技能潜力及心理表现特点的认定上,对不同气质的运动员在训练过程中出现的生理和心理变化,原则上也可以通过医易科学的相关理论进行分别调整,说明医易科学体质学说在运动员早期选材和系统训练上都具有可行性。  相似文献
