Evaluating Online Mathematics Resources: A Practical Approach For Teachers, Boris Handal, Parvan Handal, Anthony J. Herrington
Evaluating Online Mathematics Resources: A Practical Approach For Teachers, Boris Handal, Parvan Handal, Anthony J. Herrington
Faculty of Education - Papers (Archive)
Gradually Internet-based educational resources are making their way into the school mathematics curriculum (Handal & Herrington, 2003). Online resources are potentially useful compared to normal courseware because of their abundance, availability at no cost, platform-free accessibility, and their wide reaching accessibility. On the other hand, a major limitation of online resources is their lack of appropriate pedagogy, coupled with poor instructional design and layout. According to Alessi and Trollip (2001, p. 392), “The tendency for the Web to be used only for presentation of materials greatly restricts its instructional potential”.
Identifying Authentic Mobile Learning In Teacher Education: A Design-Based Approach, Anthony J. Herrington, Janice A. Herrington

The adoption of mobile technologies in higher education has been variable and inconsistent across the sector. Little is known about how people learn best from mobile devices such as mobile phones, personal digital assistants and portable digital audio players, and yet these are the technologies of choice of a generation of young adults who are proficient and competent in their use. This paper describes a project to explore, implement and document pedagogies that go beyond the use of mobile technologies for information delivery and communication. It describes a design-based approach to researching the use of mobile devices as cognitive tools …
A Semiparametric Model Approach For Financial Bankruptcy Prediction, Maria H. Kim, Paul Yoo
A Semiparametric Model Approach For Financial Bankruptcy Prediction, Maria H. Kim, Paul Yoo
Faculty of Commerce - Papers (Archive)
In this study, we propose a model that achieves both accurate modeling and sustainable model stability for corporate bankruptcy prediction. This model is to model the given samples accurately as well as to respond adequately to the unknown inputs by employing semiparametric approach where parametric model and nonparametric Neural Networks (NNs) are combined. By exploring the structural relationships within the available sample data, the proposed model is assumed to retain the advantages of both parametric and nonparametric models. The proposed model is compared to pure parametric models such as Multivariate Discriminant Analysis (MDA) and Logistic Regression (LR), and pure nonparametric …
An Ontology-Based Approach For Expert And Knowledge Mining In Complex Multi-Agent Systems, Minjie Zhang, Xijin Tang, Quan Bai, Jifa Gu
An Ontology-Based Approach For Expert And Knowledge Mining In Complex Multi-Agent Systems, Minjie Zhang, Xijin Tang, Quan Bai, Jifa Gu

Complex problems require diverse expertise and multiple techniques to solve. In order to solve such problems, complex multi-agent systems include numbers of heterogeneous agents, which may include both of human experts and autonomous agents, to work together toward some complex problems. Most complex multi-agent systems are working in open domains. Due to heterogeneities and dynamic working environments, expertise and capabilities of agents might not be well estimated and presented in the system. Therefore, how to discover useful knowledge from human and autonomous experts, make more accurate estimation for experts' capabilities and to find out suitable expert(s) to solve incoming problems …
A System For The 3d Reconstruction Of The Human Face Using The Structured Light Approach, Dean Mcguire, Prashan Premaratne
A System For The 3d Reconstruction Of The Human Face Using The Structured Light Approach, Dean Mcguire, Prashan Premaratne

This paper will describe a computer vision system under development with the aim of use in robust facial recognition applications. The system employs the structured light approach to solve the correspondence problem. The system has been designed with ease of use in mind with calibration procedures designed to be simple enough to be carried out without the use of precision measuring equipment, but robust enough to provide good quality 3D reconstructions. The hardware in use is of consumer grade and is being used in an unmodified form. Early reconstructions of faces based on the projection of a striped pattern have …
Maintaining Social Marketing's Relevance: A Dualistic Approach, Gary I. Noble
Maintaining Social Marketing's Relevance: A Dualistic Approach, Gary I. Noble
Faculty of Commerce - Papers (Archive)
There have been calls amongst academics and practitioners to move social marketing 'upstream'. This paper attempts to clarify what upstream social marketing is, its appropriate relationship with ‘downstream’ social marketing and how both approaches can be combined into a suitable theoretical framework. The paper argues that neither up or downstream social marketing is superior and suggests that a dual, synergistic approach is needed. This argument is supported through reference to current social marketing interventions in the areas of road safety and childhood obesity. The paper concludes by suggesting that Polonsky, Carlson and Fry’s (2003) ‘harm chain’ concept may be a …
An Analytic Approach To Spectral Flow In Von Neumann Algebras, M-T Benameur, Alan L. Carey, John Phillips, Adam C. Rennie, Fyodor A. Sukochev, K P. Wojciechowski
An Analytic Approach To Spectral Flow In Von Neumann Algebras, M-T Benameur, Alan L. Carey, John Phillips, Adam C. Rennie, Fyodor A. Sukochev, K P. Wojciechowski
Faculty of Engineering and Information Sciences - Papers: Part A
The analytic approach to spectral flow is about ten years old. In that time it has evolved to cover an ever wider range of examples. The most critical extension was to replace Fredholm operators in the classical sense by Breuer-Fredholm operators in a semifinite von Neumann algebra. The latter have continuous spectrum so that the notion of spectral flow turns out to be rather more difficult to deal with. However quite remarkably there is a uniform approach in which the proofs do not depend on discreteness of the spectrum of the operators in question. The first part of this paper …
An Agent-Oriented Approach To Change Propagation In Software Evolution, Khanh Hoa Dam, Michael Winikoff, Lin Padgham
An Agent-Oriented Approach To Change Propagation In Software Evolution, Khanh Hoa Dam, Michael Winikoff, Lin Padgham
Faculty of Engineering and Information Sciences - Papers: Part A
Software maintenance and evolution are inevitable activities since almost all software that is useful and successful stimulates user-generated requests for change and improvements. One of the most critical problems in software maintenance and evolution is to maintain consistency between software artefacts by propagating changes correctly. Although many approaches have been proposed, automated change propagation is still a significant technical challenge in software engineering. In this paper we present a novel, agent-oriented approach to deal with change propagation in evolving software systems that are developed using the Prometheus methodology. A metamodel with a set of the Object Constraint Language (OCL) rules …
A Numerical Approach To Evaluate The Fatigue Life Of Monolimb, Nian-Zhong Chen, Winson Lee, Ming Zhang
A Numerical Approach To Evaluate The Fatigue Life Of Monolimb, Nian-Zhong Chen, Winson Lee, Ming Zhang
Faculty of Engineering and Information Sciences - Papers: Part A
Monolimb refers to a transtibial prosthesis with the prosthetic socket and the shank being molded into one piece of thermoplastic material. Shank flexibility of a monolimb can improve gait and comfort. However, fatigue failure of monolimbs under cyclic walking load is an important concern. This study is to evaluate the fatigue life of a monolimb designed for a transtibial amputee, based on finite element analysis, the statistical Miner's rule and reliability analysis. Stress uncertainty due to modeling error and the scatter in fatigue test data were considered. Results indicated that the accuracy of fatigue life evaluation of monolimb depends significantly …
