Two Studies Of The Empirical Basis Of Two Learning Resource-Oriented Motivational Strategies For Gifted Educators, Anamaria Vladut, Wilma Vialle, Albert Ziegler

Faculty of Social Sciences - Papers (Archive)

Two learning resource-oriented motivational strategies for gifted educators are introduced: a homeostatic orientation that aims for balance and an allostatic orientation that aims at growth. In order to establish the empirical basis of these motivational strategies, two studies were conducted with samples of students from a specialized post-secondary business school who were enrolled in grades 11–13. Study 1 focused on the empirical basis of the homeostatic orientation. It was shown that the availability of learning resources is associated with two forms of balance within an actiotope: robustness and resilience. Furthermore, it could be shown that the effects of exogenous learning …

Influence Of Steel Fibres On The Behaviour Of Rpc Circular Columns Under Different Loading Conditions, Ahmed Al-Tikrite, Muhammad N. S Hadi

Faculty of Engineering and Information Sciences - Papers: Part B

An experimental program was conducted to investigate the effect of inclusion of steel fibres on the behaviour of Reactive Powder Concrete (RPC) columns. Three different types of steel fibre were used: micro straight steel fibre (MF), macro deformed steel fibre (DF) and waste steel fibre (WF) recovered from discarded tyres. In addition, a hybridization of steel fibres was made up to produce waste-industrial hybridization (WHF) (MF, DF and WF). Twenty reinforced RPC column specimens were prepared and tested under axial concentric, eccentric and flexural loading. Results of testing demonstrated that the ultimate axial load and the corresponding axial deformation increased …

Behaviour Of Carbon Fibre-Reinforced Polymer-Confined Hollow Circular Concrete Columns With Inner Polyvinyl Chloride Tube, Hussamaldeen Goaiz, Tao Yu, Muhammad N. S Hadi

Faculty of Engineering and Information Sciences - Papers: Part B

Existing studies have shown that the use of an inner tube can significantly enhance the effectiveness of confinement in fibre-reinforced polymer-confined hollow columns. The inner tube used in the existing studies, however, generally had a large stiffness and also served as longitudinal reinforcement. The use of a stiff inner tube is inefficient in resisting bending for hollow columns with a relatively small void and may be unnecessary for constraining the inner surface of concrete. Against this background, this article presents the first experimental study on fibre-reinforced polymer-confined hollow columns with an inner polyvinyl chloride tube. The experimental program included a …

Local Buckling Of Steel Plates In Concrete-Filled Steel Tubular Columns At Elevated Temperatures, Ghanim Mohammed Kamil, Qing Quan Liang, Muhammad N. S Hadi

Faculty of Engineering and Information Sciences - Papers: Part B

Local buckling remarkably reduces the strength of steel plates in rectangular thin-walled concrete-filled steel tubular (CFST) columns at ambient temperature. This effect is more remarkable at elevated temperature. However, there have been very limited experimental and numerical investigations on the local and post-local buckling behavior of steel plates in CFST columns at elevated temperatures. This paper presents numerical studies on the local and post-local buckling behavior of thin steel plates under stress gradients in rectangular CFST columns at elevated temperatures. For this purpose, finite element models are developed, accounting for geometric and material nonlinearities at elevated temperatures. The initial geometric …

Dose metrics for PTVs and organs at risk were compared to analyze any differences …

Development And Evaluation Of An Mre-Based Absorber With Two Individually Controllable Natural Frequencies, Jie Yang, Shuaishuai Sun, J Chi, Donghong Ning, Haiping Du, Shan-Wen Zhang, Weihua Li, Shixin Mao

Faculty of Engineering and Information Sciences - Papers: Part B

Adaptive tuned mass absorbers, which are based on magnetorheological elastomer (MRE) have been widely accepted for vibration absorption due to their frequency shift capability. Wider frequency bandwidth indicates more effectiveness in reducing vibrations. In order to broaden the effective bandwidth of the MRE-based absorber, this study proposes a new design consisting of an eccentric mass. This design enables the absorber to have two natural frequencies: the rotational natural frequency and the translational one. These two natural frequencies can be controlled separately by adjusting the MRE stiffness and the eccentric length. This design not only broadens the effective bandwidth of the …

Position Control Of A Soft Prosthetic Finger With Limited Feedback Information, Solen Kumbay-Yildiz, Rahim Mutlu, Gursel Alici

Faculty of Engineering and Information Sciences - Papers: Part B

One of the challenging research questions in soft robotics is the establishment of valid mathematical models and control techniques under limited feedback conditions. A soft robotic system will typically have a continuum or monolithic body seamlessly embodying its actuation and sensing elements, accompanied by mechanical structure, and even the energy source, much like a biological system. In this study, we propose a relay sliding mode controller based on the input - output model (RSMC-IO), which is a simple but effective control approach that does not require a complete system model, to control the tip position of a soft prosthetic finger, …

Driver Intention Based Coordinate Control Of Regenerative And Plugging Braking For Electric Vehicles With In-Wheel Pmsms, Wenfei Li, Haiping Du, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part B

Electric vehicles have been the focus of the automotive industry in recent years. However, relatively small driving range of electric vehicles makes it not be broadly adopted in the market. Regenerative braking is one of the most effective ways to extend the endurance of electric vehicles. To sufficiently utilise the regenerative braking of electric vehicles and explore the potential of the electric motor plugging braking capability to simplify the braking system structure and reduce the cost, a new braking strategy based on the driver's braking intention and motor working characteristics is proposed. Driver's braking intention is classified as the emergency …

Modeling Supply Network Configuration Problems With Varying Demand Profiles, Subodha Dharmapriya, Senevi Kiridena, Nagesh Shukla

Faculty of Engineering and Information Sciences - Papers: Part B

In this paper, we develop a novel multi-objective modeling approach to support supply network configuration decisions, while considering varying demand profiles. In so doing, we illustrate how such an approach could contribute to building supply network robustness and resilience. The proposed model entails two key objectives; minimizing lead time and cost across the supply network. The solution approach first employs a bidding mechanism to select a set of supply network entities that match with a given demand profile from a candidate pool of entities. It then applies the popular technique known as N on-dominated Sorting Genetic Algorithm-II to generate a …

External referencing takes many forms, which have different resourcing requirements, outcomes, and operational strengths and challenges. This paper describes the External Referencing of Standards (ERoS) approach developed, tested and adopted by a university consortium. ERoS draws on the strengths of existing methodologies to produce an evolved model that is …

Don't Just Stay In Your Lane: Developing Digital Literacies Freestyle, Courtney A. Shalavin

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

Digital literacies are no longer optional for higher education staff - they are a necessity. However, comprehensive solutions on how to develop digital literacies in the workforce remain elusive. While many institutions implement clear definitions and frameworks in policies at the macro-level, rigid application of these tools is ineffective at a micro-level wherein personalized approach is needed. This paper describes the approach of a pilot professional development program at a regional university library that scopes and evolves to meet the needs of the workforce. The program is guided by design principles focusing on personalization and flexibility. In the future, the …

Preparing Quality Teachers: Bridging The Gap Between Tertiary Experiences And Classroom Realities, Corinne Green, Michelle J. Eady, Peter J. Andersen

Faculty of Social Sciences - Papers (Archive)

There are many factors that impact student learning, with quality educators being one of the most important elements for student success. Accordingly, the promotion of quality teacher preparation programs has become a priority for tertiary institutions, researchers, policymakers, and practitioners. There is a known disparity between tertiary experiences and classroom realities that leave graduate teachers feeling unprepared for the teaching profession. Employing a contextualized learning approach such as situated learning theory in teacher preparation programs can reduce this gap and successfully prepare graduate teachers for the teaching arena. This research project surveyed one cohort (n=154) at the conclusion of a …

Strategies Of Policy Advocacy Organizations And Their Theoretical Affinities: Evidence From Q-Methodology, Sheldon Gen, Amy Conley Wright

Faculty of Social Sciences - Papers (Archive)

Policy advocacy is an increasingly important function for many nonprofit organizations, yet their advocacy activities have largely escaped theoretical grounding. The literature on nonprofits has described how they engage in policy advocacy, without linking them to theories of policy change. The policy studies literature, on the other hand, has explained how various forms of influence result in policy change, but has largely ignored organizational perspectives on those processes. These two literatures remain largely disconnected. Drawing upon interviews with a purposive sample of policy advocacy directors at 31 nonprofit organizations, this study applies Q-methodology to identify and describe six distinct policy …

Ethnic Diversity, Scarcity And Drinking Water: A Provocation To Rethink Provisioning Metropolitan Mains Water, Gordon R. Waitt

Faculty of Social Sciences - Papers (Archive)

Urban water scarcity in south-east Australia forces us to engage with how our present centralised public utilities are embedded in our everyday lives, amidst uncertain futures. In the last decades, socio-technical approaches have illustrated how the myth of endless main water supply is made possible by cultures of engineering and plumbing. To extend debates about the cultural dimensions of environmental sustainability, this paper takes an ethnographic approach to understand the processes by which Burmese refugees and migrants who lived with water scarcity pre-migration make water potable post-migration to Australia. With a focus on mapping the material, discursive, spatial and emotional …

'Our Lives' And 'Life Happens', From Stigma To Empathy In Young People's Depictions Of Sexual Health And Relationships, Kate Senior, Laura Grozdanovski, Richard D. Chenhall, Stephen Minton

Faculty of Social Sciences - Papers (Archive)

This article describes qualitative research undertaken to explore young people's understanding of sex and relationships that used a scenario-driven body-mapping technique. This art-based method was designed to allow young people to think deeply about the subject and build upon each other's ideas through the medium of decorating a life-sized human body. Although this method produced rich information the depictions of young people tended to be highly stigmatized. We further refined the method to encourage young people to empathize with the character that they created and the resultant research became the basis for the sexual health resource 'Life Happens'.
