Technoliteracy, teacher agency and design: Shaping a digital learning culture

Despite educational directives advocating the integrated use of technology, some staff remain resistant to the adoption of computer-mediated classroom practice. As resistance is sometimes akin to lack of confidence or understanding, this thesis sought to illuminate the nature of work for teachers and students in a digital environment. It reports on a descriptive and interpretive case study on the classroom experiences of teachers and senior secondary school students in two humanities subjects where technology use was integrated with literacy practices for learning (technoliteracy). Findings suggest that there is a role for technology in the learning process and that student learning might be enhanced by constructivist-based, computer-mediated activities. These findings seem to confirm the important role of teacher agency in designing classroom experiences that capitalise on the potential of new technologies of communication for effective student learning. Furthermore, this thesis has synthesised key ideas from constructivism, educational technology and learning theory with study findings to generate a supportive framework that might encourage techno-reluctant teachers to engage productively with technology in meaningful ways. It develops a grounded model for technoliteracy that gains its dynamism from the notion of design. With its related constructs of "teacher-as-designer" of classroom digital learning environment and "students-as-designers" of electronic representations of knowledge, this model suggests a purposeful integration of technology and literacy practices towards a more critical appreciation of subject content. The thesis also offers practical guidelines for applying constructivist principles to promote technoliteracy and a digital learning culture. The evaluative criteria developed from the SOLO Taxonomy and specially designed for analysing the student-created electronic artefacts also offer possibilities for reconceiving the choice of texts, activities and assessment for students of the 21st century. From the theoretical and practical perspectives shaping this study, this thesis could prompt other teachers to imagine new possibilities for digital learning and to pioneer new models for teaching and learning in increasingly borderless classrooms in the knowledge age. It could encourage techno-reluctant staff to engage in computer-mediated learning practices.
Die Parther und ihre Beziehungen zur griechisch-römischen Kultur

Gleich zu Beginn ist eine Bemerkung erforderlich. Bevor man zum eigentlichen Thema, also dem Verhältnis der Parther und Irans zum Hellenismus, überhaupt zur griechisch-römischen Kultur, übergehen kann, scheint es zweckmäßig, die Frage zu stellen, wie sich das Verhältnis des Hellenismus zu den Parthern, ihrer Kultur, darstellt. Es ist klar, daß die alte Vorstellung, die mit dem Namen J . G. Droysens verbunden ist, nicht mehr befriedigt. Die Veränderungen, denen die allgemeine Weltlage in der letzten Zeit unterlag, und die zunehmende Bolle des Orients haben neue Möglichkeiten zur Beurteilung auch der Alten Geschichte geschaffen. Das hat beispielsweise Franz Altheim gesehen, indem er W. W. Tarn kritisierte, für den Iran der hellenistischen Zeit nicht weit vom Standpunkt eines Engländers Indien gegenüber entfernt war. Es ist also an der Zeit, dies alles zu berücksichtigen, ohne dabei zu vergessen, daß freilich schon im Altertum die griechisch-römischen Schriftsteller die Iranier, vor allem die Parther, als Barbaren zu bezeichnen pflegten, was auch von den Zeitgenossen übernommen wurde. Jetzt, frei von diesen Vorurteilen, fällt es uns leichter, uns über zwei Probleme, also über Einstellung Irans zu diesen zwei mächtigen Strömungen, der Hellenisierung und der Romanisierung, zu äußern. Es lassen sich aber Grundunterschiede in der Behandlung dieser zwei Tendenzen hinsichtlich Irans feststellen. Die erste, die Hellenisierung, der Hellenismus überhaupt, entwickelte sich im Vergleich mit der Romani-
Information Coding in a language: Some insights from Pān. inian Grammar

The knowledge of how a language codes information, how much information it codes and where it codes is very crucial for a computational linguist working in the area of Natural Language Processing and in particular Machine Translation. Pān. ini has given utmost importance to the information coding in a language string. This is evident from the use of the same marker N. twice making the pratyāhāras apparently ambiguous. In support of our claim that Pān. ini had information coding at the back of his mind while writing the grammar for Sanskrit in the form of As.t . ādhyāȳi, we discuss as representatives the 3 sūtras: anabhihite (3.1.1), svatantrah. kartā (1.4.54) and samānakartr . kayoh. pūrvakāle (3.4.21). These 3 sutras precisely point out where the information is coded, how much information is coded and the manner in which the information is coded in Sanskrit.
An Iterative Approach to Minimize access Delay and Jitter for Streaming Media over Internet

Delay and jitter are important performance metrics for streaming media as they are known to directly impact user experience. There are several sources of delay observed for streaming media in the internet such as the propagation delay, encoder delay, decoder delay and access delay to name a few. Significant amount of research has gone into minimizing different source of delay to provide a better user experience. The objective of this work is to present an analytical framework to achieve minimum access delay and jitter at the source of a streaming media characterized by variable bit-rate arrivals. Among several performance enhancing techniques for streaming high quality media, we focus on the impact of linear coding-based rate control at the transport layer as it has been established that coded transmission at the transport layer provides better overall performance for streaming media transmission. Since the development of practical network coding, many approaches have achieved receiver-based optimum delay as the decoding delay is considered to be an important element affecting network throughput. However, our work looks at the streaming system from the perspective of the source and aims to optimize the delay caused at the transmitter. Consequently, we formulate a dynamic programming problem to optimize access delay and jitter costs at the source for a streaming system based on the Markov Decision Process (MDP) model, to analyze a network-coded transport layer. Linear coding influences rate control at the transport layer and we analyze its impact on the streaming flow from an end-to-end perspective. For timely and uninterrupted streaming, achieving optimal queue service at the sender is essential and we use an approximate dynamic programming algorithm, "Value Iteration" to arrive at acceptable minimum access delay and jitter by maintaining the span norm error close to almost zero.
Software Metrics and Software Metrology

Most of the software measures currently proposed to the industry bring few real benefits to either software managers or developers. This book looks at the classical metrology concepts from science and engineering, using them as criteria to propose an approach to analyze the design of current software measures and then design new software measures (illustrated with the design of a software measure that has been adopted as an ISO measurement standard). The book includes several case studies analyzing strengths and weaknesses of some of the software measures most often quoted. It is meant for software quality specialists and process improvement analysts and managers.

An Experimental Multimodal Disputation System

An experimental multimodal disputation system , Mr.Bengo, is a knowledge based system with multimodal user interfaces such as face recognition, face generation, speech recognition , speech generation and a WWW browser. Mr. Bengo deals with three agents-a prosecution , an defense attorney and the judge. The prosecution and the attorney dispute about the interpretation of legal rules. The user controls the defense attorney to dispute with the prosecution. After the disputation nishes, the judge decides the winner. As the disputation is a two agent game, to predict the opponent's move is important to win the game. During disputation of the Mr. Bengo, the face of each agent c hanges according to the status of disputation. Using the face information, the user knows if the prosecution nds the counter argument or not, which helps him to search the good next move.
Development of letter-speciWc processing: The eVect of reading ability

During development, perceptual processing is tuned to inputs in the environment such that certain frequently encountered classes of stimuli are processed more eVectively than similar comparison stimuli. Letters represent a class of stimuli that are encountered frequently in the environment, at least in literate cultures. Thus, the present study examined the development of letter-speciWc processing in children 6–19 years old by comparing the diVerence between performance on a letter-matching task and an unfamiliar non-letter-matching task in diVerent subject groups. Results revealed an increase in letter-speciWc processing with development. Moreover, comparisons of letter-speciWc processing in groups of subjects matched either in age or reading ability indicate that the emergence of letter-speciWc processing is linked to increased reading skill, rather than increased age per se. Findings support theories of perceptual expertise, which suggest that skilled processing drives the specialization of perceptual mechanisms for certain classes of stimuli.  2005 Published by Elsevier B.V.

Managing Medical Ontologies using OWL and an e-business Registry / Re-pository

This paper outlines how the knowledge embedded in OWL and medical ontologies support e-Health web service deployment that may involve the interaction of independent resources from different domains and owned by different entities. In particular, it (1) identifies how the OASIS Business Centric Methodology guidelines apply to the development and publishing challenges for medical information that is required by agents representing the e-Health stakeholders and (2) how the enterprise content management capabilities of the ISO/TS 15000 ebXML Registry / Repository are being used to manage standards based (e.g., HL7 CDA, GEHR) medical records and assist the discovery process.
A 9-bit 20-MSample/s Pipeline ADC for NTSC Video Decoders

This paper presents a 9-bit, 20 MSample/s pipeline analog-to-digital converter (ADC) for NTSC video decoders. The sharing amplifier technique is employed to reduce the overall number of the amplifiers wherein dynamic comparators are adopted to reduce the power consumption. The proposed design is implemented by 0.35 μm CMOS technology. The post-layout simulation results show that the maximum power consumption is 45mW given a 3.3 V power supply, and the SFDR is 54 dB with a sinusoidal input at 5 MHz. The ADC occupies 2.75 mm on silicon
Frameworks for Intra- and Interprocedural Dataflow Analysis

Because dataflow analyses are difficult to implement from scratch, reusable dataflow analysis frameworks have been developed which provide generic support facilities for managing propagation of dataflow information and iteration in loops. We have designed a framework that improves on previous work by making it easy to perform graph transformations as part of iterative analysis, to run multiple analyses “in parallel” to achieve the precision of a single monolithic analysis while preserving modularity and reusability of the component analyses, and to construct contextsensitive interprocedural analyses from intraprocedural versions. We have implemented this framework in the Vortex optimizing compiler and used the framework to help build both traditional optimizations and non-traditional optimizations of dynamically-dispatched messages and first-class, lexically-nested functions.
Multi-cultural visualization : how functional programming can enrich visualization (and vice versa)

The past two decades have seen visualization flourish as a research field in its own right, with advances on the computational challenges of faster algorithms, new techniques for datasets too large for in-core processing, and advances in understanding the perceptual and cognitive processes recruited by visualization systems, and through this, how to improve the representation of data. However, progress within visualization has sometimes proceeded in parallel with that in other branches of computer science, and there is a danger that when novel solutions ossify into `accepted practice' the field can easily overlook significant advances elsewhere in the community. In this paper we describe recent advances in the design and implementation of pure functional programming languages that, significantly, contain important insights into questions raised by the recent NIH/NSF report on Visualization Challenges. We argue and demonstrate that modern functional languages combine high-level mathematically-based specifications of visualization techniques, concise implementation of algorithms through fine-grained composition, support for writing correct programs through strong type checking, and a different kind of modularity inherent in the abstractive power of these languages. And to cap it off, we have initial evidence that in some cases functional implementations are faster than their imperative counterparts.
Image Compensation Algorithm for Holographic Data Storage System

Abstract 본 논문에서는 확대, 축소, 회전 등과 같은 선형, 비선형 왜곡이 포함된 이미지에 대해, 이미지의 외곽선을 찾아서 이미지를 보정하고 싱크 마크(Sync. Mark)를 사용하여 데이터를 샘플링하는 알고리즘을 제안한다. 외곽선을 찾기 위한 방법으로 허프 변환(Hough Transform)을 사용하였으며, 찾아낸 외곽선을 이용하여 이미지의 영역을 인식하고, 이미지의 왜곡을 줄이기 위하여 이미지 와핑(warping) 기법을 적용하였다. 이미지의 비선형 왜곡을 보상하기 위하여 이미지의 싱크 마크(Sync. Mark)를 공분산(covariance)을 사용하여 인식하고 샘플링 위치를 보정하였다. 또한, 제안된 알고리즘은 Over Sampling 자체를 하나의 이미지 확대로 인식하여 처리하기 때문에 어떠한 Over Sampling 에도 적용 가능하다. Key Words : 홀로그램, 이미지 보정 알고리즘, 허프 변환, 이미지 와핑. 1. 서 론 홀로그래픽 WORM (write once read many) 시스템은 DVD (digital versatile disk) 와 같은 기존의 광 정보 저장장치가 2차원 평면에 순차적으로 정보를 기록하는 것과는 달리 2차원의 정보 영상을 volume 에 중첩 기록하여 높은 저장 밀도와 빠른 정보 전달 능력을 가진다[1-3]. 이 경우 기록과 재생시 간섭이나 기록 물질의 불균일성 등의 영향으로 검출 정보에 잡음이 포함되게 되어 신뢰성 있는 정보 복원을 위한 신호처리 기술들이 필요하다[4][5]. 그러나 CCD나 CMOS와 같은 이미지 센서를 사용하여 데이터를 복원 할 때, 측정 이미지의 보정 없이 데이터를 샘플링할 경우 광학적인 이미지 왜곡으로 인해 데이터 정정 알고리즘만으로는 처리할 수 없는 많은 오류가 발생할 수 있다. 이러한 이미지의 왜곡을 광학적인 방법만을 사용하여 보정하기에는 큰 어려움이 따르므로 이미지 보정을 위한 알고리즘이 반드시 필요하다. 본 논문에서는 이미지의 Over Sampling 수에 관계없이 이미지의 확대, 축소, 회전등과 같은 광학적 선형, 비선형 왜곡을 보정하여 데이터를 추출(sampling)할 수 있는 알고리즘을 제안한다.

Analyzing search engine queries for the use of geographic terms

Millions of Web users seek information every day for business or private purposes on topics which cover the whole spectrum of human knowledge and interest, ranging from the mundane to the highly esoteric. However, users in general appear unwilling to learn new techniques for improving the relevance of their searches. Research suggests that any such improvement must be based around the “intelligent” interpretation of user queries by the search engines with the minimum of user feedback. The understanding of how users actually use geographic terminology could play an important part in developing search engines capable of interpreting user queries. The aim of this study was to analyse the 2001 Excite query log to investigate the extent and variation of Web queries containing geographic terms. In particular it was an investigation into what people search for when they use geographic terms, the ways in which they describe a geographic location, the terminology used to find geographically related information and the structure of users’ queries when looking for geographically related information on the Web. This study also attempted to determine how geographically related queries differ from other queries. The results show that geographic terms form a significant part of the vocabulary of Web users and suggest that this is an area worth pursuing to improve the retrieval effectiveness of search engines. Geographically related queries formed nearly one fifth of all queries submitted to the Excite search engine, the terms occurring most frequently being place names. Geographic queries were also shown to be longer than average and the association of two or more terms within geographic queries was found to be high, thus suggesting that phrase analysis may be an important feature required of search engines. However, it was not possible to assess the effectiveness of the queries since there was no information available on what the user is actually looking for, nor on the results obtained.
Evaluation and further development of an e-portfolio system (EPS) for initial teacher education

Resulting from the evaluation of the in-house electronic portfolio system which included the development of evaluation forms for trainees and tutors and capturing over 4000 words of comments, recommendations are made regarding the development of an e-portfolio system for initial teacher training. Revisions undertaken to improve the user interface included; enhanced memory, storage, backup and server provision; labelling of links and actions; more icons for file types; file upload and disk usage limits to increase to 50MB; shared folders renamed and repositioned, improved monitoring of emails for tutors; zip files of whole directory structures to be uploaded and easier folder deletion. Implementing this for tutors and for trainees is seen to be an effective way forward to learn about and experience a secure, monitored, flexible and efficient building and sharing of electronic resources.
On Using Correlation-based Synopses during Query Optimization

In recent years, a variety of complex synopsis structures have been proposed to capture statistical correlations present in database relations. The goal of that work has been to improve cardinality estimation during query optimization by improving statistics on "base tables". In order to use the correlation information for multi-table estimations as well, synopses must also be constructed on "intermediate result tables" during query optimization. We address that problem here, and show how to efficiently integrate multi-dimensional histograms and other complex synopsis structures into the search algorithm of a traditional query optimizer such as that of System R. A main challenge in this work is minimizing the computational expense of dynamically computing synopses on intermediate tables during query optimization. We show that one only needs to construct a very small subset of all possible synopses to get the full estimation benefits of multi-dimensional modeling. We also show that choosing this subset unwisely can have unacceptable performance overheads. This leads to an "estimation planning" problem that has been ignored to date in literature: how to choose the most efficiently-computable collection of intermediate synopses to construct, so that all the required cardinality estimates can be computed as accurately as possible from the base-table synopses? In this paper, we identify and formalize the estimation planning problem in the context of a System R-style optimizer extended with complex synopsis techniques such as multi-dimensional histograms. We propose algorithms that find very good estimation plans efficiently, and discuss properties of synopsis structures that make them amenable to efficient use in an optimizer.
Intra-Operative Position Sensing and Tracking Devices

Intra-operative position sensing and tracking devices are fundamental building blocks which are often used in Computer-Assisted Orthopaedic Surgery (CAOS). These devices are used during surgery to precisely localize conventional surgical tools, rigid anatomical structures, other medical imaging equipment (e.g., X-Ray or ultrasound scanners), surgical implants, etc. For example, in computer-assisted spine surgery, it may be desirable to determine the position and orientation of a drill relative to a vertebral body. Intra-operative sensors can be used to independently measure the locations of the vertebral body and the drill, and then the relative position and orientation can be inferred. In this abstract, the term position sensor refers to a type of sensor which can localize one or more discrete points in 3-D space. Such sensors can also compute object orientation when 3 or more measured points are attached to a single rigid object. The term surface sensor refers to a type of sensor which can measure the bounding surface of an object (e.g., the surface of a bone). In this abstract, characteristics and examples of both sensor types are presented.
An RSA with Customized Public Key

To speed up RSA operation, one tempt is to use short exponents. Recently, Sun and Yang designed a new variant RSA with balanced prime factors and trade-off exponents. Using Sun and Yang's method, it is successful in designing variants of RSA in which the public and private exponents can be chosen obviously smaller than those in typical RSA. However, their RSA variants don't provide the use of public key of special form 2+1, which can further reduce the encryption cost. In this paper, we design a new RSA variant which not only remains the same property as the previous RSA variants, but also provides that the public exponent can be the special form of 2 + 1.
