Models of Knowledge Restructuring. In a world of rapid change, people must frequently adapt cognitive skills to new technologies. This often requires restructuring of knowledge, from simple initial strategies to increasingly complex ways of mastering the task. This is not always easy and people sometimes resist knowledge restructuring. We present a network model of knowledge restructuring that combines attentional processes with error-driven learning. The model accounts for several existing resu ....Models of Knowledge Restructuring. In a world of rapid change, people must frequently adapt cognitive skills to new technologies. This often requires restructuring of knowledge, from simple initial strategies to increasingly complex ways of mastering the task. This is not always easy and people sometimes resist knowledge restructuring. We present a network model of knowledge restructuring that combines attentional processes with error-driven learning. The model accounts for several existing results and makes predictions that guide the proposed research. Three factors will be examined empirically: (1) the role of directing attention to alternative strategies; (2) the imperfection of existing knowledge; and (3) the complexity of alternative strategies.Read moreRead less
Advancing the science of willpower: investigating the mechanisms and processes of self-control. Willpower or 'good' self control is important for success in our academic, occupational, and social lives. This project will use cutting-edge scientific methods to investigate how glucose, the primary fuel for body function, promotes 'good' self-control and stimulates regions in the brain important for self-control.

This project aims to improve the coverage, mobile access, miniaturisation, bandwidth and networking of optical wireless. As connected machines become the primary consumers of the Internet, technologies for wirelessly connecting devices, processors, storage and display devices at very high speeds become necessary for mission critical services and applications. Gigabit wireless access needs to overcome shortages in the radio-frequency spectrum and provide scalable bandwidth and wider coverage. Optical wireless transmission is a real alternative to current wireless systems because its connection speed of tens of gigabits/second means it can work efficiently with wired optical networking technologies. This project is expected to lead to optical wireless technology.Read moreRead less
Containment and Reduction of Rework in Transport Mega Projects. Mega transport projects (>$1 billion) are poorly managed during their construction with significant cost and schedule overruns and benefit shortfalls regularly being experienced.

Mega transport projects (>$1 billion) are poorly managed during their construction with significant cost and schedule overruns and benefit shortfalls regularly being experienced. Having to perform rework has been identified as a major factor that contributes to these unintended consequences. As there has been limited research that has empirically examined rework causation, an inability to develop effective rework containment and reduction strategies prevails. This research aims to develop a theoretical model that can be used to develop robust containment and reduction strategies to mitigate the adverse economic, productivity and safety consequences that materialize from performing rework during the construction of mega transport projects.Read moreRead less
