The University of Arizona Composition Program has demonstrated that computers can be integrated successfully into composition instruction. Administrators and instructors are preparing to offer students in second-semester Freshman Composition (English 102) a computer-integrated course of instruction as the equipment and facilities become available. Chapter I relates how current research shows that computers offer support to current theories in composition and that they can be utilized in all the various processes involved with producing university writing. It explores the problems program directors and university administrators face in providing computer technology to undergraduates in writing courses. Chapter II compares the reactions of Southern Arizona Writing Project teacher-participants with freshman students in a pilot section of English 102 at the University of Arizona and with comparable undergraduates at other universities as they learn to use word processors as a tool for writing. Some differences between the older SAWP participants and the undergraduates were observed, especially a greater computer anxiety and a greater of urgency to learn about computers. The SAWP participants had less time to become proficient computer writers than did the freshmen. All these factors probably contributed to their lower success rate as computer writers. Nevertheless, a large majority of all ages of computer writers recognize the benefits of using word processors for writing and even those SAWP participants who made only limited progress expressed a sense of satisfaction at having mastered the machine. Chapter III describes ways that computer writing and strategies of collaborative learning and peer review were adapted to the syllabus of English 102 in a pilot class at the University of Arizona. Students reacted favorably to both computers and to the teaching strategies. However, the vision of total computer integration resulting in a paper-free writing course cannot be achieved without either restructuring the syllabus or acquiring substantially improved computer facilities, especially through networked workstations and computerized classrooms.

The present dissertation aims to evaluate the phenomenon of visual masking as a tool for studying visual awareness focusing on two-alternative forced choice (2AFC) discrimination tasks. Two existing theories of masking - Bachmann's (1984) perceptual retouch theory and Marcel's (1983) recovery theory - are discussed along with the global neuronal workspace theory of awareness (Baars. 1989; Dehaene, Kerszberg, & Changeux, 1998). Performance accuracy on Semantic discrimination is compared to that on Orthographic discrimination as an indication of a potential difference between semantic and orthographic processing of masked word stimuli presented for 40 ms and 50 ms. This is further compared to an e-detection task previously used as an indicator of awareness in some masked priming experiments. Together, these tasks are further evaluated in terms of their relationship with participants' subjective reports collected in the form of confidence ratings. The implications and predictions drawn from the theories of masking and visual awareness as well as the notion of partial awareness (Kouider & Dupoux, 2001) are assessed taking into account the data obtained in the current experiments.The relevance of these data for masked priming is determined by performing a comparison between 2AFC discrimination and detection tasks, and the lexical decision task. An ERP study is also presented, in which Semantic and Orthographic discrimination as well as e-detection are paired with confidence ratings and electrophysiological recordings in search of an ERP component that can be correlated with both subjective (confidence) and objective (performance) measures of awareness. A binding account of visual awareness with special attention paid to visual masking is proposed and compared to the three existing theories.

The present study investigated the effects of concurrent reading and listening--in the form of the Reading While Listening (RWL) technique--as a means of improving word recognition and reading comprehension among intermediate L2 readers and compared these effects to a distinct top-down reading pedagogy in the form of Extensive Reading (ER) approach, an integrated pedagogy of both RWL and ER and a Control pedagogy of silent in-class reading. Drawing upon innate acquisitional mechanisms of phonological recoding as articulated by Jorm & Share's (1983) Self-Teaching Hypothesis (STH), the present research suggested the simultaneous presentation of identical orthographic and aural input as an ideal protocol for the exploitation of such a route to fluent word recognition in reading. Drawing upon innate acquisitional mechanisms of cognitive inferencing and whole language development as proposed by Goodman (1967, 1988), Krashen (1995, 2007) and Day & Bamford (1998), the present study also proposed the ER pedagogical approach as an effective top-down mechanism for cognitive inferencing in reading and whole language development as well as a tool for addressing L2 reader affect. In order to investigate the efficacy of RWL and ER respectively, while also as an integrated composite pedagogy of both RWL and ER, the present study employed a mixed-methods quasi-experimental design incorporating longitudinal classroom treatments of RWL, ER, RWL-ER and Control reading pedagogies over five weeks and among 51 intermediate ESL readers. Univariate and multivariate statistical analyses, alongside qualitative data reduction and display, supported the respective and significant efficacy of RWL and ER reading pedagogies over Control treatments on measures of reading rate, comprehension, vocabulary and grammatical knowledge gains as well as reader affect. Moreover, the composite RWL-ER treatment group demonstrated superlative gains above all other treatment types in a manner that supports the distinct advantages of such an integrated reading pedagogy, which pairs acquisitional approaches to both bottom-up word recognition and top-down cognitive skills development in tandem. Pedagogical implications for these findings are discussed alongside limitations and area for future research.

Since it was introduced in Forster and Davis (1984), masked priming has been widely adopted in the psycholinguistic research on visual word recognition, but there has been little consensus on its actual mechanisms, i.e. how it occurs and how it should be interpreted. This dissertation addresses two different interpretations of masked priming, one based on the Interactive Activation Model (McClelland & Rumelhart, 1981), in which priming is seen as a result of persisting activation from the prime, the other based on the Entry Opening Model (Forster & Davis, 1984), which sees priming as a savings effect. Five experiments are reported testing contrasting hypotheses about the role of prime duration and prime-target asynchrony (SOA) in masked priming using both identity and form priming. Overall, this dissertation lends support to the Entry Opening Model, demonstrating that masked priming is essentially a savings effect, and that as such, it is determined by the SOA, not the prime duration per se.

社會網路分析（social network analysis）將社會關係以網路形式表示，從原本純粹分析社會互動的工具，到近年來被廣泛被應用在社會學、組織研究、資訊科學、生物學、語言學等各種領域，藉由引入數學圖學理論與與日益精進的電腦處理能力，使得社會網路分析能從有別於以往的角度找出個體間行動的規律；而詞義相似度（word similarity）是資訊檢索等技術發展的基礎課題之一，近年來對詞義相似度的量測有許多方法的提出。 本研究針對英語字詞利用社會網路分析這樣的工具，藉由提出不同的網路建構方式，以語料庫為資料來源，設定網路節點與連結關係，以共現網路（co-occurrence networks）為基礎，經由改變產生與篩選的條件，觀察以社會網路分析已有的性質或指標做調整，是否可以對詞義相似度提供另一種量測方式；同時以目前詞義相似度研究上已有同義詞標準評比對前述產生的網路與所計算的性質做驗證，並進一步探討使用社會網路分析在詞義相似度研究上的適用性。

The current study examined the phonological process of prosodic ability in a model of adult word reading and reading comprehension ability. All phonological tasks involve executive functions (EF) reflected in an individual’s flexibility for manipulating different components of language. To account for the EF demands involved in phonological tasks of reading, EF was assessed using measures of inhibitory control and switching attention as both a control variable and predictor in each model of reading. Two research questions guided the study: 1) Do prosodic ability and EF make independent contributions to word reading, and reading comprehension ability when controlling for the other? 2) Do prosodic ability and EF make unique contributions to word reading, and reading comprehension ability when controlling for the other, in addition to controlling for vocabulary, fluid (nonverbal) intelligence, rapid automatized naming (RAN - Digits), and phonological short-term memory (PSTM)? Participants were one hundred and three native-English speaking adults (18 to 55 years of age) recruited from Eastern Ontario. A total of 8 regression models were tested. The analyses revealed unique contributions of prosodic ability in adult word reading achievement, and EF in silent reading comprehension. Prosody’s contribution to word reading above EF supports prosodic awareness as a phonological skill that can be used to explain individual differences in word reading, whereas EF’s contribution to reading comprehension supports its’ role in more complex reading tasks. Prosody and EF represent constructs that warrant future consideration in models of reading. / Thesis (Master, Education) -- Queen's University, 2013-12-19 16:15:50.64

Semantic distance is a measure of how close or distant in meaning two units of language are. A large number of important natural language problems, including machine translation and word sense disambiguation, can be viewed as semantic distance problems. The two dominant approaches to estimating semantic distance are the WordNet-based semantic measures and the corpus-based distributional measures. In this thesis, I compare them, both qualitatively and quantitatively, and identify the limitations of each. This thesis argues that estimating semantic distance is essentially a property of concepts (rather than words) and that two concepts are semantically close if they occur in similar contexts. Instead of identifying the co-occurrence (distributional) profiles of words (distributional hypothesis), I argue that distributional profiles of concepts (DPCs) can be used to infer the semantic properties of concepts and indeed to estimate semantic distance more accurately. I propose a new hybrid approach to calculating semantic distance that combines corpus statistics and a published thesaurus (Macquarie Thesaurus). The algorithm determines estimates of the DPCs using the categories in the thesaurus as very coarse concepts and, notably, without requiring any sense-annotated data. Even though the use of only about 1000 concepts to represent the vocabulary of a language seems drastic, I show that the method achieves results better than the state-of-the-art in a number of natural language tasks. I show how cross-lingual DPCs can be created by combining text in one language with a thesaurus from another. Using these cross-lingual DPCs, we can solve problems in one, possibly resource-poor, language using a knowledge source from another, possibly resource-rich, language. I show that the approach is also useful in tasks that inherently involve two or more languages, such as machine translation and multilingual text summarization. The proposed approach is computationally inexpensive, it can estimate both semantic relatedness and semantic similarity, and it can be applied to all parts of speech. Extensive experiments on ranking word pairs as per semantic distance, real-word spelling correction, solving Reader's Digest word choice problems, determining word sense dominance, word sense disambiguation, and word translation show that the new approach is markedly superior to previous ones.

The problem investigated in this study is the following: “What is the nature and function of the theme of God’s speech in the book of Hebrews and within the whole of the revelation in Scripture?”. This problem can only be solved if the unfolding nature of God’s speech from the Old to the New Testament is taken into account (cf. Heb 1:1-2), the theme is researched grammatical-historically, and then placed revelational-historically within the whole of Scripture. The introductory questions of the book of Hebrews are investigated for the potential light that answers to these questions can shed on the appearance, function and interpretation of references to God’s speech in the book. Subsequently, the structure of Hebrews is investigated and analysed to determine the position which the theme of God’s speech assumes within the sermon. This goal is achieved through a literature study on suggestions for Hebrews’ structure, followed up by an independent thought structure analysis of Hebrews according to the method of Coetzee (1988a:19-37). From the position of the theme of God’s speech within the structure of the sermon the nature and content of the author of Hebrews’ references to the theme of God’s speech as introductory formulae, and as part of Old Testament quotations themselves, are determined. This is done by examining the 38 introductory formulae in Hebrews in detail on the basis of a literature and independent study. Subsequently, eleven pericopes in Hebrews where keywords of the theme of God’s speech come together as part of the argumentation of the sermon are researched grammatical-historically using a combined method of Coetzee (1997), Tolar (2002), Jordaan (2004a) and Fee (2009). Ultimately it is determined how the theme of God’s speech unfolds in the book of Hebrews regarding manner, nature and content by giving an overview of the collected material by means of analysis, interpretation and synthesis. From this overview it is determined how the author of Hebrews’ theme of God’s speech fits into the whole of God’s revelation in Scripture. This is achieved by doing a cursory revelational-historical study using a combined method of Coetzee (1995) and Jordaan (2003) on six topics that form the overview of the theme of God’s speech in Hebrews. Finally, a general conclusion is reached by answering the problem of this study by way of enumeration: The revelational-historical importance of the theme of God’s speech in Hebrews is that the author shares the presupposition of other biblical authors that the Old Testament is divinely inspired and therefore absolutely authoritative, but then with the explicit emphasis that God is presently still speaking directly and urgently with man through it. The unfolding of God’s revelation also has a specific accentuation in Hebrews by means of the author’s emphasis that God revealed Himself superior and finally in his Son. The author of Hebrews’ emphasis on the greater responsibility of the hearers to listen faithfully and obediently because of God’s superior revelation in his Son, is also unique. For these reasons alone Hebrews has an indispensable role within the Canon. / PhD (New Testament), North-West University, Potchefstroom Campus, 2014

The main aim of the study was to determine which measurement tool, existing or adapted, would be able to determine the levels of customer centricity within the sales channels of a specific organisation, operating in the South African financial industry. A literary study showed that in order to determine the levels of customer centricity, customer experience should be measured. Six questionnaires were administered, namely, EXQ, NPS, CES, Customer satisfaction, Word-of-Mouth and Behavioural loyalty intention. The data showed a statistical significance and a positive relationship between all the constructs within all the questionnaires except with that of CES. / MBA, North-West University, Potchefstroom Campus, 2014

This thesis describes basic research into visual word recognition and decision making. Determining the best matching lexical representation for a given stimulus involves interactions between representations. The standard task for studying these processes is the lexical decision task (LDT), but there is still debate regarding the factors that affect how individuals make lexical decisions. The nature of lexical interactions and the processes underlying lexical decision-making were addressed here by testing response congruency effects in the masked priming variant of the LDT. The results of seven masked priming experiments showed a robust response congruency effect that depends on the difficulty of the word-nonword discrimination. This finding resolved apparent inconsistencies in previous research. The experiments were simulated using the Bayesian Reader and the Spatial Coding Model (SCM). The probability based Bayesian Reader model failed to accommodate the findings. However, a good fit to the data was provided by a modified version of the SCM in which the assumptions regarding the nature of lexical interactions were changed such that word nodes inhibit only (closely) related competitors. The model also assumes that the difficulty of the word-nonword discrimination affects the degree to which stimulus typicality informs lexical decisions. A critical issue for these experiments involved the definition of orthographic typicality. An algorithm for measuring orthographic typicality and for generating nonwords with a specific level of orthographic typicality (OT3) was developed. An unprimed LDT experiment showed that OT3 affected decision latency even when other standard measures of orthographic typicality were controlled. Two additional masked priming experiments showed that highly typical primes lead to faster word responses and slower nonword responses than less typical primes. Overall, the results of this research enhance our understanding of the processes underlying visual word recognition and lexical decision making, and also have important methodological implications for the field.
