Achieving Data Quality in a Statistical Agency : A Methodological Perspective THE EFFECT OF RECORD LINKAGE ERRORS ON STATISTICAL INFERENCE IN COHORT MORTALITY STUDIES

The advent of computerized record linkage methodology has facilitated the conduct of cohort mortality studies in which exposure data in one database are electronically linked with mortality data from another database. In this article, the impact of linkage errors on estimates of epidemiological indicators of risk such as standardized mortality ratios and relative risk regression model parameters is explored. It is shown that these indicators can be subject to bias and additional variability in the presence of linkage errors, with false links and nonlinks leading to positive and negative bias respectively in estimates of the standardized mortality ratio. Although linkage errors always increase the uncertainty in the estimates, bias can be effectively eliminated in the special case in which the false positive rate equals the false negative rate within homogeneous states defined by cross-classification of the covariates of interest.
TECHNOLOGICAL SUPPORT FOR INQUIRY-BASED LEARNING: DEVELOPMENT AND USE OF DIGITAL RESOURCES IN SCIENCE EDUCATION WITHIN THE EUROPEAN PROJECT PROFILES

Has been noticed a decline in students' interest in learning science. It is necessary, therefore, an implementation of teaching strategies that enable students to understand the usefulness of learning science and relevance of scientific knowledge. Given the unquestionable importance of pedagogical integration of technology, the design of digital learning resources can be relevant to motivate and encourage the involvement of young people in the construction of learning. It is this philosophy that fits PROFILES European project, and its predecessor PARSEL. This paper will present the basic principles of these projects, also referring to the potential of inquiry in the teaching and learning of science. In close connection with the inquiry and educational technology this paper also presents two examples of digital educational resources, developed by us, to enhance the learning of science, more effective and meaningful for students.
A graphical representation schema for the software process modeling language MVP-L

Experience gathered from applying the software process modeling language MVP-L in software development organizations has shown the need for graphical representations of process models. Project members (i.e„ non MVP-L specialists) review models much more easily by using graphical representations. Although several various graphical notations were developed for individual projects in which MVP-L was applied, there was previously no consistent definition of a mapping between textual MVP-L models and graphical representations. This report defines a graphical representation schema for MVP-L descriptions and combines previous results in a unified form. A basic set of building blocks (i.e., graphical symbols and text fragments) is defined, but because we must first gain experience with the new symbols, only rudimentary guidelines are given for composing basic symbols into a graphical representation of a model.
Rits-QA: List answer detection and Context task with ellipses handling

In this paper, we describe RitsQA: Ritsumeikan question answering system. We have improved our QA system submitted in QAC1 in subcategorization of NE type and question type analysis and in handling numerical expressions using corpus based approach. We also participated subtask 2 and 3 using these core QA systems. We have implemented list answer detection module for subtask 2 and ellipsis handling module for subtask 3. We had evaluations of subtask 1, 2 and 3. According to Formal Run evaluation, our QA system had some progress in some aspects. Especially in subcategorization of NE types, we have obtained better improvement in performance of core QA system. In subtask 2 and 3, we have a little success in detection of the number of answers from surface pattern of question sentence. Also, in ellipsis handling, almost 37% of follow-up questions was correctly treated in ellipsis. However, it is necessary to expand patterns of ellipsis and improve list answer processing.
Calculus: Concepts and Methods

Book description: The pebbles used in ancient abacuses gave their name to the calculus, which today is a fundamental tool in business, economics, engineering and the sciences. This introductory book takes readers gently from single to multivariate calculus and simple differential and difference equations. Unusually the book offers a wide range of applications in business and economics, as well as more conventional scientific examples. Ideas from univariate calculus and linear algebra are covered as needed, often from a new perspective. They are reinforced in the two-dimensional case, which is studied in detail before generalisation to higher dimensions. Although there are no theorems or formal proofs, this is a serious book in which conceptual issues are explained carefully using numerous geometric devices and a wealth of worked examples, diagrams and exercises. Mathematica has been used to generate many beautiful and accurate, full-colour illustrations to help students visualise complex mathematical objects. This adds to the accessibility of the text, which will appeal to a wide audience among students of mathematics, economics and science.

Ontologies - Description and Applications

The word “ontology” has gained a good popularity within the AI community. Ontology is usually viewed as a high-level description consisting of concepts that organize the upper parts of the knowledge base. However, meaning of the term “ontology” tends to be a bit vague, as the term is used in different ways. In this paper we will attempt to clarify the meaning of the ontology including the philosophical views and show why ontologies are useful and important. We will give an overview of ontology structures in several particular systems. A field proposed within ontological efforts, “ontological engineering”, will be also described. Usage of ontologies in several particular ways will be discussed. These include systems and ideas to support knowledge base sharing and reuse, both for computers and humans, ontology based communication in multiagent systems, applications of ontologies for natural language processing, applications in documents search and enrichment of knowledge bases, both particularly for the World Wide Web environment and construction of educational systems, particularly intelligent tutoring systems.
Properties of scientific periodicals under bibliometric assessment

The methods of bibliometric research of scientific periodicals are studied much better than the properties of periodicals though the latter are the subject of the assessment. Since the properties in most cases are not being evaluated directly, the problem is to identify the intermediate that is DIRECTLY evaluated by a concrete method and to determine, which specific property of a scientific periodical is reflected by this intermediate most ADEQUATELY. Such an attempt is underwent in the present work for practically all the methods that are used in corresponding studies of periodicals. By means of philosophical speculations the author finds out the "method property" conformities. scientific periodicals, bibliometric assessment, value, productivity, impact, citation analysis, publication count, document handling data, document use, questionnaire survey, peer assessment
Power-Efficient Routing Algorithm for Torus NoCs

The advance of semiconductor technology, which has led to more than one billion transistors on a single chip, has enabled designers to integrate dozens of IP (intellectual property) blocks together with large amounts of embedded memory. These advances, along with the fact that traditional communication architectures do not scale well have led to significant changes in the architecture and design of integrated circuits. One solution to these problems is to implement such a complex system using an on-chip interconnection network or network-on-chip (NoC). The multiple concurrent connections of such networks mean that they have extremely high bandwidth. Regularity can lead to design modularity providing a standard interface for easier component reuse and improved interoperability.The present thesis addresses the performance analysis and design space exploration of NoCs using analytical and simulation-based performance analysis approaches. At first, we developed a simulator aimed to performance analysis of interconnection networks. The simulator is then used to evaluate the performance of networks topologies and routing algorithms since their choice heavily affect the performance of NoCs. Then, we surveyed popular mathematical formalisms – queueing theory, network calculus, schedulability analysis, and dataflow analysis – and how they have been applied to the analysis of on-chip communication performance in NoCs. We also addressed research problems related to modelling and design space exploration of NoCs.In the next step, analytical router models were developed that analyse NoC performance. In addition to providing aggregate performance metrics such as latency and throughput, our approach also provides feedback about the network characteristics at a fine-level of granularity. Our approach explicates the impact that various design parameters have on the performance, thereby providing invaluable insight into NoC design. This makes it possible to use the proposed models as a powerful design and optimisation tool.We then used the proposed analytical models to address the design space exploration and optimisation problem. System-level frameworks to address the application mapping and to design routing algorithms for NoCs were presented. We first formulated an optimisation problem of minimizing average packet latency in the network, and then solved this problem using the simulated annealing heuristic. The proposed framework can also address other design space exploration problems such as topology selection and buffer dimensioning.
Small groups in human-robot interaction

Most research in human-robot interaction so far has focused on one robot and one person. Such situations have been evaluated in order to enable the robot to act appropriately. However, often interaction occurs in groups. Groups, even if they are small, require novel robot abilities such as detecting who is talking to whom or how to behave. The paper focuses on small group research and relates it to human-robot interaction by introducing very first results of an experimental user study with 80 users (40 pairs) that was conducted to determine the perception of the robot in a small group object-teaching scenario.
Exploring a technology-facilitated part-complete solution method for learning computer programming

Leaming to program is now a requirement in many courses of study in such areas as computer science, infonnation technology, infonnation systems, multimedia, engineering, and science. However, research indicates that many students have great difficulties in learning to program and this results in high failure rates and high levels of withdrawal from academic courses. It is accepted that programming is an intrinsically difficult subject however the teaching and learning methcds used in many programming courses have changed little over the years. Tht' literature indicates the importance of reducing the cognitive load that students experience when learning programming and that one method that has potential to do this uses part-complete program solutions. This study sought to explore a technology supported part-complete solution method (TSPCSM) for the le. ,ming of computer programming. A teaching and learning framework for programming was developed and a technology supported "COde Restucturing Tool'1, CORT, was then designed around the learning framework and developed to support the part-complete solution method and provide a suitable learning environment. A quasi-experimental research design framework was utilised in the study which used both qualitative and quantitative research methods. A series of programming problems was developed for CORT and an experiment was undertaken with students who were studying introductory programming. Experimental and control groups were utilised in the experiment which took place over a 14 week semester at an Australian university The data were analysed and they provided rich information concerning three research questions relating to the part-complete solution method (PCSM) through CORT: how students engaged with CORT; how CORT supported the learning process; and how CORT impacted upon their learning outcomes. Results from the study indicated that the PCSM within CORT imposed a low cognitive load on students; provided high levels of cognitive support; strong scaffolding for learning; and students engaged well with the system and generally used a thoughtful and considered strategy to solving programming problems. No differences in learning achievement were found between the experimental and control groups, however other findings indicated that the students who used the PCSM within CORT required significantly less time and less help than the control group

An investigation of knowledge intensive approaches to concept learning and theory refinement

Concept learning algorithms have been used to solve difficult problems in fields ranging from medical diagnosis to astronomy. In spite of their successful application, most concept learners are only able to utilize knowledge that is expressed in the form of a set of training examples. Relevant knowledge from other sources can not be utilized even when it is available. Evidence is presented that using knowledge from other sources leads to more accurate learned models. This dissertation is an investigation of techniques for utilizing knowledge in the form of an approximate theory to facilitate concept learning. The techniques explored are divided into two classes: theory-guided learning algorithms which use the approximate theory to constrain the search for a new concept description, and theory revision algorithms which attempt to repair the approximate theory. While both techniques are more accurate than approaches that ignore the information contained in the approximate theory, experimental evidence indicates that theory revision algorithms produce more accurate models. Furthermore, these models are structurally more similar to both the approximate theory and the "ideal" theory, than those produced by theory-guided learning algorithms. The main contributions of this dissertation include: a new approach to theory-guided learning, a conceptual framework for comparing and evaluating theory revision algorithms, enhanced techniques for identifying and repairing errors within a theory, and a lexically enhanced approach to evaluating repairs. Lexically enhanced theory revision is a novel technique for utilizing a previously unused form of knowledge contained in the approximate theory. The technique uses lexical information contained in the term names of the approximate theory to prefer repairs that are lexically more coherent. Evidence indicates that this further reduces the structural difference between the revised theory and the "ideal" theory.
A global approach to a global resource: an invesigation into the archiving of web 2.0 records around the world

The purpose of this dissertation was to explore how different countries are approaching archiving Web 2.0 records and to ascertain if a global approach would be appropriate or practical. Archives that capture and preserve web-based material from three different countries were approached. Data was collected by analysing their policy documents and conducting semi-structured interviews by email. The results showed that there were no significant differences in the approaches and attitudes of different countries when archiving Web 2.0 records. Participants agreed on the lack of direct influence of society on appraisal decisions, the potential of Web 2.0 records for new types of researchers, and the need to engage with creators of Web 2.0 software and records to enable these resources to be archived successfully. All participants expressed concerns with various technical and practical issues, but didn’t see these as complete barriers to archiving web-based material. Legislation and legal issues were regarded as less of an active concern by respondents than was expected. Collaboration and cooperation was a recurrent theme and played a role in various stages and areas of archiving Web 2.0 records. It was concluded that the different archival traditions of various countries would not cause a problem in establishing collaborative practices, and that a global approach to archiving Web 2.0 records would not only be possible, but would actively be encouraged and embraced by institutions.

Automatic Lipreading to Enhance Speech Recognition (Speech Reading)

Automatic recognition of the acoustic speech signal alone is inaccurate and computationally expensive. Additional sources of speech information, such as lipreading (or speechreading), should enhance automatic speech recognition, just as lipreading is used by humans to enhance speech recognition when the acoustic signal is degraded. This paper describes an automatic lipreading system which has been developed. A commercial device performs the acoustic speech recognition independently of the lipreading system. The recognition domain is restricted to isolated utterances and speaker dependent recognition. The speaker faces a solid state camera which sends digitized video to a minicomputer system with custom video processing hardware. The video data is sampled during an utterance and then reduced to a template consisting of visual speech parameter time sequences. The distances between the incoming template and all of the trained templates for each utterance in the vocabulary are computed and a visual recognition candidate is obtained. The combination of the acoustic and visual recognition candidates is shown to yield a final recognition accuracy which greatly exceeds the acoustic recognition accuracy alone. Practical considerations and the possible enhancement of speaker independent and continuous speech recognition systems are also discussed.
CritLink: Advanced Hyperlinks Enable Public Annotation on the Web

This paper describes a set of hypertext linking features that are essential for supporting critical discussion and document annotation, but are missing from the Web. An implementation of these features called “CritLink” enables users to attach annotations to any location on any public page, and to view the annotations on any page, without having to install any special client or server software. All browsers (including text-only browsers) and all operating systems are supported. Annotations can have types, can be public or private, and can annotate other annotations.

Standard Cell Placement by Quadrasection

In this paper we describe a new placement technique based on hypergraph quadrasection. We developed a standard cell placement procedure based on recursively dividing the netlist into four parts, while minimizing the division cost. We have extended the {\em Min-Cut Bisection} algorithm to handle quadrasection. We discuss the implementation details and our results show our implementation to be superior to the simulated annealing code TimberWolf.
