Development And Validation Of An Australian Database For Estimating The Seafood Content Of Canned Products, Elizabeth Neale, Yasmine Probst, Marijka Batterham, Linda C. Tapsell

Faculty of Health and Behavioural Sciences - Papers (Archive)

Canned fish products are of increasing popularity in Australia; however current Australian nutrient databases do not include data on the percentage fish in these products. The objective of this study was to develop and validate a database of the percentage fish and seafood contained in common canned fish and seafood products, for use in clinical trials. Six major supermarkets in the Illawarra region, NSW were audited for canned seafood products, and a database of re-ported percentage fish and seafood was developed. Mean + SD of each type of product was then determined. To vali-date the database, a representative sample of …


Towards Greater Systemisation In Ci Research: An Exploration Of Social Development As A Framework For Comparison And Understanding, William Tibben Jan 2011

Towards Greater Systemisation In Ci Research: An Exploration Of Social Development As A Framework For Comparison And Understanding, William Tibben

Faculty of Informatics - Papers (Archive)

The theme of complexity alludes to the difficulties community informatics (CI) researchers face when analysing use of ICTs by communities. In response, de Moor (2009a, 2009b) and Stillman (2010) identify the need for greater systemisation of CI research that enables complex socio-technical processes to be analysed over multiple cases. The principle by which such systemisation should occur is open to debate. It seems improbable that a single theoretical approach, at least in the short term, is going to satisfy everyone as greater systemisation is pursued. The paper suggests that, as a first step, efforts should be devoted to better appreciation …


Development Of A Peer-To-Peer Information Sharing System Using Ontologies, Ghassan Beydoun, Graham Low, Numi Tran, Paul Bogg Jan 2011

Development Of A Peer-To-Peer Information Sharing System Using Ontologies, Ghassan Beydoun, Graham Low, Numi Tran, Paul Bogg

Faculty of Informatics - Papers (Archive)

Most existing agent-oriented methodologies ignore system extensibility, interoperability and reusability issues. Ontologies have been found to play a significant role in facilitating interoperability, reusability, MAS development activities (including MAS analysis and agent knowledge modeling) and MAS run-time operation (including agent communication and reasoning). However, most of the existing AOSE methodologies do not provide support for ontology-based MAS development. We present software engineering requirements for ontology-based development for MAS and examine an existing methodology, MOBMAS - a "Methodology for Ontology-Based MASs", which makes use of ontologies as a modeling tool. In this examination, we highlight how MOBMAS can be extended to …


On The Relationship Between Population Change And Sustainable Development, Simone Marsiglio Jan 2011

On The Relationship Between Population Change And Sustainable Development, Simone Marsiglio

Faculty of Business - Papers (Archive)

This paper investigates the relationship between population growth and economic growth, through the study of fertility choices and their effects on natural resources. It aims at analyzing the interactions between endogenous fertility choices and the environment and their link to the sustainable matter. We analyze a growth model driven by natural resources and without production, where agents have jointly to determine consumption and fertility, taking into account the effects of their decisions on the dynamics of natural resources. We adopt the most optimistic view on natural capital (it generates endogenous growth) and the weakest notion of sustainable paths (all variables …


The Role Of The Government In Financial Sector Development, Arusha Cooray Jan 2011

The Role Of The Government In Financial Sector Development, Arusha Cooray

Faculty of Commerce - Papers (Archive)

This study examines the impact of two dimensions of the government, namely, size and quality, on two dimensions of the financial sector, size and efficiency, in a cross section of 71 economies. The study finds that increased quality of the government as measured by governance and legal origin positively influences both financial sector size and efficiency. The size of the government proxied by government expenditure and the government ownership of banks has a negative effect on financial sector efficiency, and a positive impact on financial sector size, particularly in the low income economies.


The Pathogenesis Of Human Papillomavirus (Hpv) In The Development Of Cervical Cancer: Are Hpv Vaccines A Safe And Effective Management Strategy?, Roslyn Judith Wilyman Jan 2011

The Pathogenesis Of Human Papillomavirus (Hpv) In The Development Of Cervical Cancer: Are Hpv Vaccines A Safe And Effective Management Strategy?, Roslyn Judith Wilyman

Faculty of Law, Humanities and the Arts - Papers (Archive)

Human Papillomavirus (HPV) infection has been linked with cervical cancer. Some medical professionals see it as the determining causal agent and therefore promote vaccination as an effective prevention strategy. However, the biological plausibility of a causal theory requires that the incidence of the causal agent varies with the incidence and mortality of the disease. Yet the incidence and mortality of cervical cancer do not vary with the incidence of infection with HPV strains 16 and 18; the strains covered by the HPV vaccine. Though HPV infection is a necessary precursor to most cervical cancer, most high-risk HPV infections (with one …

Research To Establish A Systematic Approach To Safe Welding Procedure Development Using Austenitic Filler Material For Fabrication Of High Strength Steel, Lenka Kuzmikova, John Norrish, Huijun Li, Mark Callaghan Jan 2011

Research To Establish A Systematic Approach To Safe Welding Procedure Development Using Austenitic Filler Material For Fabrication Of High Strength Steel, Lenka Kuzmikova, John Norrish, Huijun Li, Mark Callaghan

Faculty of Engineering and Information Sciences - Papers: Part A

High strength, thermo-mechanically treated steels often require very careful control of welding procedures to ensure freedom from hydrogen assisted cold cracking (HACC) in the weld metal and heat affected zone (HAZ) whilst avoiding undue loss of heat affected zone strength. In practice this leads to restricted operating envelopes and the requirement for rigorous procedure management. An alternative approach is the use of austenitic welding consumables but whilst this may be expected to expand the process parameter envelope its use is often restricted by adherence to procedures previously developed for ferritic consumables. The current paper describes the research undertaken to establish …


Development Of Sediment-Infilled Rock Joint Models And Implications On Rockmass Stability, Buddhima Indraratna, Wuditha N. Premadasa, David Oliveira, H S. Welideniya Jan 2011

Development Of Sediment-Infilled Rock Joint Models And Implications On Rockmass Stability, Buddhima Indraratna, Wuditha N. Premadasa, David Oliveira, H S. Welideniya

Faculty of Engineering - Papers (Archive)

Soil-infi lled discontinuities adversely infl uence the stability of rockmass, because, the infi ll materials especially when saturated, drastically reduce the shear strength. The angle of shearing resistance of a discontinuity decreases signifi cantly for increasing infi ll thickness. Once it reaches a critical thickness, the shear strength of the discontinuity will be governed only by the infi ll material and the rock-walls effect becomes negligible. Owing to the lack of research on the shear behavior of infi lled rock joints, it has been common practice to assume that the shear strength of the joint is that of the infi …


Development And Validation Of Calibration Methods For Discrete Element Modelling, Andrew Grima, Peter W. Wypych Jan 2011

Development And Validation Of Calibration Methods For Discrete Element Modelling, Andrew Grima, Peter W. Wypych

Faculty of Engineering - Papers (Archive)

Discrete element method (DEM) is proving to be a reliable and increasingly used tool to study and predict the behaviour of granular materials. Numerous particlescale mechanisms influence the bulk behaviour and flow of bulk materials. It is important that the relevant measurable input parameters for discrete element models bemeasured by laboratory equipment or determined by physical calibration experiments for rational results. This paper describes some of the bench-scale experiments that have been developed to calibrate the DEM simulations to reflect actual dynamic behaviour. Relevant parameters such as static and rolling coefficients of friction, coefficient of restitution and interparticle cohesion forces …


Development Of A Water-Mist Based Venturi System For Dust Control From Maingate Chocks And Bsl, Ting Ren, Graeme Cooper, Srinivasa Yarlagadda Jan 2011

Development Of A Water-Mist Based Venturi System For Dust Control From Maingate Chocks And Bsl, Ting Ren, Graeme Cooper, Srinivasa Yarlagadda

Faculty of Engineering - Papers (Archive)

Advances in modern longwall (LW) technology have resulted in high production faces with more powerful chocks and shearers that can advance at faster rates. As longwall chocks (supports) advance, crushed roof coal and/or rock can fall from the top of the chock canopy into the face ventilation airflow. Dust survey showed that chock movement is a significant source of dust exposure for shearer operators, accounting for about 47% of total LW face dust make during the cutting cycle. 3D CFD models have been developed to understand the behaviour of longwall dust particles from various sources including maingate (MG) chocks and …


Bauschinger Effect In Microalloyed Steels: Part Ii. Influence Of Work Softening On Strength Development During Uoe Line-Pipe Forming, Andrii Kostryzhev, Martin Strangwood, Claire L. Davis Jan 2011

Bauschinger Effect In Microalloyed Steels: Part Ii. Influence Of Work Softening On Strength Development During Uoe Line-Pipe Forming, Andrii Kostryzhev, Martin Strangwood, Claire L. Davis

Faculty of Engineering and Information Sciences - Papers: Part A

The Bauschinger effect (a reduced yield stress at the start of reverse deformation following forward prestrain) is an important factor of strength development for cold metal forming technology. In steels, the magnitude of the Bauschinger effect depends on composition, through the presence of microalloy precipitates, and prior processing, through the size and distribution of the microalloy precipitates and the presence of retained work hardening. In this article, the parameters of the Bauschinger effect and work hardening (coefficient and exponent) in forward and reverse deformations were quantitatively related to the particle number density and dislocation density for two high-strength low-alloy (HSLA) …

A Proposed Adaptation Of The European Foundation For Quality Management Excellence Model To Physical Activity Programmes For The Elderly - Development Of A Quality Self-Assessment Tool Using A Modified Delphi Process, Ana I. Marques, Leonel Santos, Pedro Soares, Rute Santos, Antonio Oliveira-Tavares, Jorge Mota, Joana Carvalho

Faculty of Social Sciences - Papers (Archive)

Background There has been a growing concern in designing physical activity (PA) programmes for elderly people, since evidence suggests that such health promotion interventions may reduce the deleterious effects of the ageing process. Complete programme evaluations are a necessary prerequisite to continuous quality improvements. Being able to refine, adapt and create tools that are suited to the realities and contexts of PA programmes for the elderly in order to support its continuous improvement is, therefore, crucial. Thus, the aim of this study was to develop a self-assessment tool for PA programmes for the elderly. Methods A 3-round Delphi process was …


Early Years Experience And Longer-Term Child Development: Research And Implications For Policymaking, Edward Melhuish Jan 2011

Early Years Experience And Longer-Term Child Development: Research And Implications For Policymaking, Edward Melhuish

Faculty of Social Sciences - Papers (Archive)

Why should we focus on the early years? One reason is the accumulation of evidence that indicates that the child's experience in the early years has profound consequences for later life. There are now many studies that present a consistent picture indicating that adversity in early life, such as frequently accompanies child poverty, is linked to: poor adult mental and physical health , adult mortality, anti-social and criminal behaviour, substance abuse and poor literacy and academic achievement.

Faculty of Engineering and Information Sciences - Papers: Part B

A range of Ultra-Thin Cast Strip (UCS) sheet steels with elevated residual levels was produced via the CASTRIP twin drum casting method at Nucor Steel, Indiana. This paper examines the influence of elevated levels of copper, chromium, nickel, and phosphorous on mechanical properties, surface quality, processing, and weldability of UCS sheet steel products produced by the CASTRIP process. Increased levels of copper and phosphorous were found to strengthen UCS sheet steel due to solid solution strengthening but chromium and nickel did not. At lower coiling temperatures and low hot reductions, where processing conditions promote microstructural strengthening, copper and chromium further …

The Effect Of Personal Digital Assistants In Supporting The Development Of Clinical Reasoning In Undergraduate Nursing Students: A Systematic Review, Karen Jeffrey, Sharon Bourgeois

Faculty of Science, Medicine and Health - Papers: part A

The knowledge and skills mandate of nurses in the 21st Century have evolved in complexity and depth. Nurses are required to engage in higher cognitive thinking processes for safe and effective practice. The ability to integrate theoretical knowledge as it applies to the individual context of the patient to prevent or amend an adverse event has born testimony to nursings’ professional development. A symbiotic relationship exists between nursing theoretical knowledge and nursing practice; however a gap exists in reality for integrating and contextualising nursing knowledge into the clinical environment following graduation from tertiary institutions.

Knowledge Sharing Through Virtual Layers In Regional Sustainable Development Networks, Rosemary A. Van Der Meer, Luba Torlina, Jamie Mustard

Faculty of Engineering and Information Sciences - Papers: Part A

Our research examines how the organisational structure facilitates knowledge sharing within the group. This case study examines a Victorian regional sustainable group using interviews and social network analysis to identify the group's organisational structure and its effect on knowledge sharing between the members. Our findings indicate that while the mixed membership, lack of hierarchy and layered structure are complex, these elements work together to provide members with a rich body of knowledge. The diversity and differences in membership are complimentary and combined can provide a more in-depth understanding of the regional sustainable development issues.

Development Of A Dc-Lsnd Welding Process For Gmaw On Dh-36 Steel, Raymond Holder, Nathan Larkin, Huijun Li, Lenka Kuzmikova, Zengxi Pan, John Norrish

Faculty of Engineering and Information Sciences - Papers: Part A

Weld induced distortion correction is a major cost within the shipbuilding industry. This paper investigates the use of an active cooling process known as Dynamically Controlled - Low Stress No Distortion (DC-LSND) Welding on DH-36 steel. Thermal profiles are obtained and distortion measurements are also achieved. Results show that the application of a localised cryogenic cooling source trailing the welding arc can significantly reduce weld induced distortion using the GMAW process. The effect of forced cooling on the weld microstructure is also observed.

Faculty of Engineering and Information Sciences - Papers: Part A

One of the features of the digital ecosystem is the integration of human cognition and socio-economic themes into the process of new product development (NPD). In a socio-economic theme-based NPD, ranking a set of product prototypes that have been designed always requires the participation of multiple evaluators and consideration of multiple evaluation criteria. Using the well-being theme-based garment NPD as a background, this paper first presents a fuzzy hierarchical criteria group decision-making (FHCGDM) method which can effectively calculate final ranking results through fusing all assessment data from human beings and machines. It then presents a garment NPD comprehensive evaluation model …

Esl Teachers And Pronunciation Pedagogy: Exploring The Development Of Teachers' Cognitions And Classroom Practices, Amanda A. Baker Jan 2011

Esl Teachers And Pronunciation Pedagogy: Exploring The Development Of Teachers' Cognitions And Classroom Practices, Amanda A. Baker

Faculty of Education - Papers (Archive)

Over the past few decades, increasing more research has examined the cognitions (knowledge and beliefs) of second language (L2) teachers. Such research has provided insight into what constitutes teachers' beliefs and knowledge about teaching, how these cognitions have developed and how they are reflected in classroom practice (see Borg, 2006). Although numerous studies have been conducted into the curricular areas of grammar and, to a lesser extent, reading and writing, even fewer have examined teachers' cognitions into pronunciation instruction. The purpose of the present study, therefore, is to explore some of the dynamic relationships that exist between L2 teachers‘ cognitions …


Infrastructure And Economic Development, Cassey Lee Jan 2011

Infrastructure And Economic Development, Cassey Lee

Faculty of Commerce - Papers (Archive)

The importance of the infrastructure sector to the process of economic growth and development has long been recognized and understood by scholars and policymakers. Without adequate infrastructure, modern commerce characterized by production specialization and exchange across markets would grind to a halt. Economic globalization would not take place without the reduction in communication and transportation costs brought about by the progress achieved in the development of infrastructure within and across countries. Thus, any attempt at understanding Malaysia’s past experiences in economic development thus requires an analysis of the role that the infrastructure has played. The purpose of this chapter is …
