Health-related physical activity: Psychological determinants, consequences, and experimental interventions. Increasingly sedentary lifestyles and physical inactivity constitute a worldwide health problem. Despite well-known benefits of physical activity, preventive-medicine interventions have had limited success.

Increasingly sedentary lifestyles and physical inactivity constitute a worldwide health problem. Despite well-known benefits of physical activity, preventive-medicine interventions have had limited success. Instead, we propose an innovative psychological approach, emphasising quality of subjective experience (flow), motivation, physical self-concept, and the transtheoretical model of behavioural change. We propose psychological determinants of physical activity and a new experimental intervention to significantly enhance health-related physical activity. The research breaks new theoretical ground, extending and integrating different theoretical perspectives, offering a synergy between qualitative and quantitative research traditions, and providing practical benefits to mental and physical health and to quality of life.Read moreRead less
Psychological determinants of physical activity across the life span and critical life-stage transitions: Cross-sectional, longitudinal causal modelling, and experimental interventions. Increasingly, sedentary lifestyles and physical inactivity are major worldwide health problems. Despite well-established health benefits of physical activity, existing medical-oriented interventions have had limited effects on increasing population-levels of activity. We propose a psychological approach, emphasiz ....Psychological determinants of physical activity across the life span and critical life-stage transitions: Cross-sectional, longitudinal causal modelling, and experimental interventions. Increasingly, sedentary lifestyles and physical inactivity are major worldwide health problems. Despite well-established health benefits of physical activity, existing medical-oriented interventions have had limited effects on increasing population-levels of activity. We propose a psychological approach, emphasizing quality of subjective experience (flow), motivation, physical self-concept, and the transtheoretical model of change. We will evaluate psychological determinants of health-related physical activity and implement experimental physical activity enhancing interventions at two critical life stages: for late-adolescents and older Australians. The proposal advances theory and methodology in a National Research Priority area, providing practical solutions to important societal problems with socioeconomic benefits for Australia.Read moreRead less
Open(ing up) goals in physical activity: What works, when, and for whom? This project aims to advance knowledge of open goals as a new goal-setting approach to optimise the adoption and maintenance of physical activity among insufficiently active individuals. This project expects to generate substantive insights into the mechanisms that explain why, when, and for whom open goals are particularly beneficial in this population. Expected outcomes include a theory of open goals that will inform phys ....Open(ing up) goals in physical activity: What works, when, and for whom? This project aims to advance knowledge of open goals as a new goal-setting approach to optimise the adoption and maintenance of physical activity among insufficiently active individuals. This project expects to generate substantive insights into the mechanisms that explain why, when, and for whom open goals are particularly beneficial in this population. Expected outcomes include a theory of open goals that will inform physical activity promotion efforts, with the potential for broad population-level dissemination and scale-up. Significant benefits include the ability to set physical activity goals that are enjoyable and intrinsically motivating to pursue, while also avoiding detrimental effects of current practice (eg high failure rates).Read moreRead less
Playing it Safe: Psychological Safety and Mental Health for Community Sport. At a time when over half of all Australians participate in organised sports it is critical to ensure that these environments are psychologically safe. The problem is that community sports clubs have no clear guidance on how to fulfil this substantial responsibility. There have been urgent calls for the development of psychological safety and mental health guidelines which have yet to be answered. This project will deliv ....Playing it Safe: Psychological Safety and Mental Health for Community Sport. At a time when over half of all Australians participate in organised sports it is critical to ensure that these environments are psychologically safe. The problem is that community sports clubs have no clear guidance on how to fulfil this substantial responsibility. There have been urgent calls for the development of psychological safety and mental health guidelines which have yet to be answered. This project will deliver the knowledge to underpin effective psychological safety and mental health guidelines for community sports with national impact. When implemented, this knowledge will help sports clubs to provide a psychologically safe environment, and promote the mental health and wellbeing of all Australians involved in organised sports.Read moreRead less
The role of intracellular calcium in fibre-type specific gene expression in skeletal muscle. Muscles contain different fibre types whose composition can be changed by activity. The aim of this proposal is to identify the intracellular mechanisms which control fibre type. Our hypothesis is that different patterns of intracellular calcium determine the pattern of gene expression which determines fibre type. Understanding how gene expression is regulated is a central issue in biology.
Intracellular calcium in intact muscle during fatigue and stretch-induced damage. Confocal microscopes can investigate intact tissues during normal function. We will develop and apply this novel approach to muscle. We expect this new approach to become a fundamental new tool for exploring muscle function under near normal conditions. Muscle pain and weakness are common disabilities in humans and we expect this new approach to provide insights into the causes and treatment of these common cond ....Intracellular calcium in intact muscle during fatigue and stretch-induced damage.

Embodied Virtues and Expertise. The Project will provide a theoretical framework for understanding expertise. Crucially, the framework will provide an account that explains the motivation of experts, and allows for the virtues of experts to be analysed and promoted. The framework will thus fill a perceived gap in professional pedagogical disciplines such as Education, Nursing Education, and Medicine, in which the concept of expertise is central, but for which an adequate theoretical framework of ....Embodied Virtues and Expertise. The Project will provide a theoretical framework for understanding expertise. Crucially, the framework will provide an account that explains the motivation of experts, and allows for the virtues of experts to be analysed and promoted. The framework will thus fill a perceived gap in professional pedagogical disciplines such as Education, Nursing Education, and Medicine, in which the concept of expertise is central, but for which an adequate theoretical framework of expertise is lacking. Academics and practitioners from these disciplines will participate in conferences and workshops run under the Project.Read moreRead less

This project investigates learning that enables people to perform well the demanding aspects of their occupations. Detailed case studies of critical incidents in a range of workplaces will be constructed and the learning or otherwise by key players involved in these incidents will be elucidated and analysed. These findings will test and refine a theory of learning at work that conceptualises it, at its best, as a growing capacity to make appropriate context-sensitive judgements. Developing a sound theory of workplace learning is very important because, though it is currently a major policy focus, received theories are of limited explanatory value.Read moreRead less
Bacterial Cell Division: Discovering how it begins and the network of protein interactions it requires. All cells must coordinate cell division with chromosome replication to ensure that the DNA is partitioned equally into newborn cells. We will establish the defect of a novel mutant blocked in the earliest stage of cell division in bacteria to obtain unique information about this vital regulatory step.

All cells must coordinate cell division with chromosome replication to ensure that the DNA is partitioned equally into newborn cells. We will establish the defect of a novel mutant blocked in the earliest stage of cell division in bacteria to obtain unique information about this vital regulatory step. We will use our newly discovered protein interaction network to establish what role protein interactions play in integrating cell division with other biological pathways in the cell to ensure its tight regulation. Our discoveries will facilitate the design of new antibiotics that target cell division to fight antibiotic-resistant bacteria and bioterrorism organisms.Read moreRead less
