How the implementation of Peer-editing Checklists Impacts the Peer Revision Process in EFL Writing Classes

This study aims to assess the efficacy of implementing checklists as a peer-editing tool within a university-level EFL writing program. Fifty-eight first-year students in two advanced-level academic writing classes participated in the study. Students used peer-review checklists, on which were delineated a comprehensive range of surface to global focus areas, as a means for proceeding systematically through the process of editing other students’ essays, and as a medium for providing corrections, suggestions, and other commentary for the student writer. At the end of the year-long course, students completed both a ranking survey and a short-answer questionnaire whereby they assessed the value of using the checklists and of participating in the peer review process. The conclusion is that peer-editing checklists, though not without their limitations, do have affective, communicative, and linguistic benefits for L2 learners in their dual roles as writers and editors.
Text and Dialogue Memorization in English Language Learning

There are three dichotomies often discussed and debated in the field of second language acquisition. One of these is the role of input vs. output, with much theory and research concerning the Input Hypothesis (Krashen, 1981) and Output Hypothesis (Swain, 1985). Another dichotomy, or distinction, is the notion of focus on form (Long, 1991) vs. exclusive focus on meaning (i.e. no overt attention to form), the latter sometimes found in certain implementations of communicative language teaching. A third dichotomy can be found in the debate over whether language learning is primarily conscious or unconscious, the former exemplified by such concepts as noticing and paying attention (Schmidt, 1990). The purpose of this article is to explore the usefulness of memorization of stories and dialogue by second language learners, particularly as it relates to the three theoretical issues mentioned above. Also discussed is the acquisition of formulaic speech and its role in the language learning process.

Design of RF CMOS Power Amplifier for UWB Applications

Ever since the FCC allocated 7.5 GHz (from 3.1 GHz to 10.6 GHz) for ultra wideband (UWB) technology, interest has been renewed in both academic and industrial circles to exploit this vast spectrum for short range, high data rate wireless applications. The great potential of UWB lies in the fact that it can co-exist with the already licensed spectrum users and can still pave the way for a wide range of applications. However, this wide bandwidth complicates the circuit level implementation of key RF blocks like the power amplifier (PA), transmit/receive switch, low noise amplifier (LNA) and mixers in an UWB transceiver. Though expensive technologies like SiGe or GaAs have been used for transceiver realizations, the ultimate goal is to have a singlechip, low-cost solution which can only be achieved by using CMOS technology. Nevertheless, some of the inherent limitations of CMOS like lower fT of transistors make the design of UWB circuits in CMOS an extremely challenging task. Two proposalsMulti-Band OFDM and Direct-Sequence CDMA have been put before the IEEE 802.15. 3a task group to decide on the industry standard for the commercial deployment of this technology. Though the debate on which standard is better has not been resolved, proponents of both the groups have already begun to develop prototypes of their respective proposals. This thesis describes the design of a key RF block in the UWB transceiver – the Power Amplifier. For the first part of this work, a PA suitable for MB-OFDM specifications was designed and fabricated in TSMC 0. 18μm CMOS technology. The class-AB PA is able to cover the lower UWB frequency band from 3.1 GHz to 4.75 GHz and delivers an output power of -2 dBm at 4 GHz. Simulated results show a gain of 19±2 dB achieved over the entire band and the PA consumes 36.54 mW from a 1.8V supply. In the second part of this work, a PA that meets the DS-CDMA specifications was designed and fabricated. This PA operates in the class-AB regime, delivering an output power of -4.2 dBm with input-1dB compression point at -22 dBm. Complete design and implementation was done using TSMC 0. 18μm CMOS technology and it consumes a very low power of 25 mW, while realizing a flat gain of 19±1 dB across the whole band of operation. All the above mentioned results are from simulations in SpectreRF and measurements are yet to be taken. Additional features like power ON/OFF scheme and output impedance control has also been incorporated in the design.
Effects of Learner Control over Feedback in Computer-Based Instruction.

Although both learner control and feedback have been heavily researched, very little research has been conducted on giving learners control over the feedback which they receive. The purpose of this study was to examine the effect of learner control of feedback in a computer assisted instruction (CAI) lesson. The independent variables were type of control (learner or program) and level of feedback (verification or elaboration), The dependent variables were performance on a posttest, attitude toward the program, and time to study feedback. The subjects, who were 100 undergraduate education majors enrolled in an educational psychology class at a large southwestern university, used one of four CAI programs which provided either program control or learner control over verification or elaboration feedback. Results indicated that subjects who received elaboration feedback during instruction performed better than students who received verification feedback. Type of control did not have a significant influence on performance. Implications of these findings for the design of CAI are discussed.

Classification context in a machine learning approach to predicting protein secondary structure

approved. Thomas G. Dietterich An important problem in molecular biology is to predict the secondary structure of proteins from their primary structure. The primary structure of a protein is the sequence of amino acid residues. The secondary structure is an abstract description of the shape of the folded protein, with regions identified as alpha helix, beta strands, and random coil. Existing methods of secondary structure prediction examine a short segment of the primary structure and predict the secondary structure class (alpha, beta, coil) of an individual residue centered in that segment. The last few years of research have failed to improve these methods beyond the level of 65% correct predictions. This thesis investigates whether these methods can be improved by permitting them to examine externally-supplied predictions for the secondary structure of other residues in the segment. The externally-supplied predictions are called the "classification context," because they provide contextual information about the secondary structure classifications of neighboring residues. The classification context could be provided by an existing algorithm that made initial secondary structure predictions, and then these could be taken as input by a second algorithm that would attempt to improve the predictions. A series of experiments on both real and simulated classification context were performed to measure the possible improvement that could be obtained from classification context. The results showed that the classification context provided Redacted for Privacy by current algorithms does not yield improved performance when used as input by those same algorithms. However, if the classification context is generated by randomly damaging the correct classifications, substantial performance improvements are possible. Even small amounts of randomly damaged correct context improves performance. Classification Context in a Machine Learning Approach to Predicting Protein Secondary Structure
The toss of tennis serves: professional vs. amateur

We compared a serve toss of different types of serve. Tennis players use different spin on the ball and various ball placements in opponent’s service box. Our aim is to compare the serve toss in different types of serve between the amateur and professional player from the view of receiving player. This is a case study. One professional tennis player and one amateur tennis player were observed while serving different types of serve. The participants served different types of the serve to various locations of opponent’s service box. We use high-speed camera, which was placed opposite to the server in the position of a receiving player. The results showed the players don’t use the same toss for each type of serve. Except individual serving style, there was no difference between the professional and amateur player. Second serves wide and to “T” or kick serve had similar toss characteristics. In some cases, the receiving players can anticipate from the server’s toss the type of the serve, therefore the tennis coaches should teach the players to use the same toss. This is very important especially in professional tennis.

Familiarization with a Forward Collision Warning on driving simulator: cost and benefit on driversystem interactions and trust

Introduire des systemes avances d'aide au conducteur dans le vehicule pourrait augmenter le confort des conducteurs et reduire le nombre d'accidents. Toutefois, des methodes d'evaluations adaptees sont necessaires a l'etude des interactions conducteur/systeme. Les systemes d'aide generent effectivement des cas d'usage critiques, i.e. des situations ou les alertes, ou l'absence d'alertes, peuvent etre negatives pour la securite. L'objectif de la recherche etait d'evaluer l'impact de la familiarisation avec les cas critiques d'usage du Forward Collision Warning (FCW) sur simulateur de conduite. Nous avons teste l'hypothese selon laquelle l'experience du fonctionnement du FCW dans des situations critiques d'usage augmente la performance de conduite et la confiance des conducteurs dans le systeme. Nous avons compare les jugements et la performance de conduite de trois groupes experimentaux: un groupe controle ou les conducteurs n'utilisaient pas le FCW, un groupe « non familiarise » ou les conducteurs utilisaient le systeme sans avoir ete familiarises et un groupe « familiarise » ou les conducteurs utilisaient le systeme apres avoir ete familiarises. Les resultats montrent que la familiarisation rend les interactions conducteur/systeme plus efficaces et plus sures. Par ailleurs, les conducteurs familiarises ont des opinions plus positives sur le FCW compare aux non familiarises. Neanmoins, la familiarisation diminue la confiance des participants dans leur capacite de conduite. De plus, elle ne permet pas d'eviter que les conducteurs depassent de facon trop precipitee les vehicules lents. Nous discutons la pertinence du simulateur pour l'etude du FCW et la possibilite de transfert des connaissances a la conduite sur route reelle. Finalement, nous proposons des ameliorations pour rendre la familiarisation avec le systeme plus efficace.
XML document representation on the Neo solution

This thesis aims to find a graph structure for representing XML documents and to implement the former representation for storing such documents. The graph structure, in fact, is the complete representation for the XML documents; this is dued to the id/idref attribute which could be present inside the XML document tag.Two different graph structures have been defined on this thesis, they are called most granular and customizable representations. The first one is the simplest way for representing XML documents, while the second one makes some improvements for optimizing inserting, deleting, and querying functions.The implementation of the former graph structures is made over a new kind of database built specifically for storing semi-structured data, such database is called Neo. Neo database works only with three primitives: node, relationship, and property. Such data model represents a new solution compared to the traditional relational view.The XML information manager implements two different API which work with the two former graph structure respectively. The first API works with the customizable representation, while the second one works with the customizable representation.Some evaluations have been done over the second implemented API, and they showed that the implemented code is free of bugs and moreover that the customizable representation brings about some improvements on making queries over the stored data.
Self Organising Maps for Anatomical Joint Constraint

The accurate simulation of anatomical joint models is becoming increasingly important for both realistic animation and diagnostic medical applications. Recent models have exploited unit quaternions to eliminate ingularities when modelling orientations between limbs at a joint. This has led to the development of quaternion based joint constraint validation and correction methods. In this paper a novel method for implicitly modelling unit quaternion joint constraints using Self Organizing Maps (SOMs) is proposed which attempts to address the limitations of current constraint validation and correction approaches. Initial results show that the resulting SOMs are capable of modelling regular spherical constraints on the orientation of the limb.
A Discourse Grammar of Mandarin Chinese

A Discourse Grammar of Mandarin Chinese focuses on the relationships between clauses in Mandarin Chinese in the functional framework. Underlying these relationships are notions like modality, presupposition, topicality, and information structure, encoded by such devices as conjunction, aspect, topic, sentence-particles and subordination. Chauncey Chu devotes a chapter to each of these devices, with a view to discovering their contribution to the coherent organization of Chinese discourse. These devices are finally integrated into a network, culminating in a proposal of the discourse sentence (represented by SENTENCE) to replace the syntactically and/or semantically defined traditional sentence. The organization of SENTENCES into paragraphs also is discussed in the framework of Rhetorical Structure Theory.

Facilitating Comprehension and Written Recall of Exposition through DRTA Instruction and Conceptual Mapping.

A training study, consisting of three treatment cycles for a total of nine 50-minute class sessions, was conducted to determine the combined effect of directed reading-thinking activity (DRTA) and conceptual mapping as organizational strategies for college freshmen of low writing ability. Each cycle included DRTA instruction, mapping, discussion, and the writing of an essay based on an expository text. Students in the control group read the same assignments and wrote essays on the same topics under the same time restrictions, but did not have DRTA or mapping instruction. Rather, the control students were taught brain storming and clustering of ideas as a planning technique for writing. Results revealed that the experimental students used significantly more main ideas in their essays than did control students, 1Nut that the experimental group of poor ability writers used slightly fewer subordinate ideas than did control group students. The findings s.Iggest that conceptual mapping and DRTA helped students recall ideas needed during the planning and writing of thesis-support and summary analysis writing tasks.
Can You Hear Me Now? Assessing Students' Classroom Communication Preferences via a Telephone Conference Activity.

Telephone conference presentation delivery was compared to face-to-face classroom delivery in an undergraduate business course setting to assess whether concern over presenting in front of the class and/or gender impacted presentation mode preference. After completing a classroom exercise, students (n=102) were surveyed and asked to compare delivery methods from two courses, one requiring a telephone conference and the other requiring a face-to-face classroom presentation, in terms of perceived effectiveness, feedback, teamwork, instructor cues, preparation time, and overall comfort. Independent sample t-test results indicated respondents who worried about presenting in front of the class believed the telephone conference format required more attention to verbal presentation quality, and they also worried more about presenting in the telephone conference format than respondents who did not worry about presenting in front of the class. In terms of gender, female respondents indicated more attention to visual aid was required during the teleconference format, believed the teleconference presentation format allowed for the same opportunity for feedback from the instructor as the formal presentation, were more likely to indicate they were concerned about speaking in front of the classroom during formal presentations, and were also more concerned about speaking during the teleconference than male respondents. Overall, results indicated the teleconference activity was perceived to be a practical alternative to the traditional face-to-face delivery method; however, females’ perceptions of discomfort across both delivery formats warrant further study.

High-performance meta-genomic gene identification ()

Computational Genomics, or Computational Genetics, refers to the use of computational and statistical analysis for understanding the structure and the function of genetic material in organisms. The primary focus of research in computational genomics in the past three decades has been the understanding of genomes and their functional elements by analyzing biological sequence data. The high demand for low-cost sequencing has driven the development of highthroughput sequencing technologies, next-generation sequencing (NGS), that parallelize the sequencing process, producing thousands or millions of sequences concurrently. Moore’s Law is the observation that the number of transistors on integrated circuits doubles approximately every two years; correspondingly, the cost per transistor halves. The cost of DNA sequencing declines much faster, which implies more new DNA data will be obtained. This large-scale sequence data, produced with high throughput sequencing technologies, needs to be processed in a time-effective and cost-effective manner. In this dissertation, we present a high-performance meta-genome gene identification framework. This framework includes four modules: filter, alignment, error correction, and gene identification. The following chapters describe the proposed design and evaluation of this pipeline. The most computationally expensive kernel in the framework is the alignment procedure. Thus, the filter module is developed to determine unnecessary alignment operations. Without the filter module, the alignment module requires 1.9 hours to complete all-to-all alignment on a test file of size 512,000 sequences with each sequence
