This interdisciplinary project explores novel machine learning approaches to modelling physical activity data in preschool children. The approach taken is considered the future of physical activity assessment and is expected to substantially enhance the measurement of physical activity and the evidence base that informs strategies to improve population health through physical activity promotion. The project aims to transform the understanding of young children's physical activity behaviour, and is expected to have important implications for the design of accurate and effective technology-based physical activity monitoring and intervention applications that could be delivered through the e-health initiative in Australia.Read moreRead less
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. Instead, we propose an innovative psychological approach, emphasising quality of subjective experience (flow), motivation, physical self-concept, and the transtheoretical model of beha ....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. 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
Furthering Positive Futures for Children with Intellectual Disabilities: A Longitudinal Investigation. This project will address the paucity of empirical research on drivers of psychosocial and physical well-being (PPW; for example self-concept, depression, behavioural problems, physical fitness, weight) of children with Intellectual Disabilities (ID). This proposal presents an extensive research program aimed at understanding the effects of school life and Physical Activity (PA) on PPW for Aust ....Furthering Positive Futures for Children with Intellectual Disabilities: A Longitudinal Investigation. This project will address the paucity of empirical research on drivers of psychosocial and physical well-being (PPW; for example self-concept, depression, behavioural problems, physical fitness, weight) of children with Intellectual Disabilities (ID). This proposal presents an extensive research program aimed at understanding the effects of school life and Physical Activity (PA) on PPW for Australian children with ID. This program examines: the relations between school life and PPW; the benefits, barriers and predictors of PA; moderators (personal characteristics, educational settings). The overarching objective is to advance theory and research in this area, and to inform intervention strategies furthering more positive futures for children with ID.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
Mobility of water in cartilage as a probe of molecular structure and function. Clinical diagnosis of early-stage osteoarthritis is difficult, and most patients are not diagnosed until a substantial degradation of cartilage has occurred as a result of the disease. This research will study the interaction between different components of articular cartilage and investigate, how this interaction can be exploited for the development of reliable and non-invasive techniques of cartilage imaging. Mobili ....Mobility of water in cartilage as a probe of molecular structure and function. Clinical diagnosis of early-stage osteoarthritis is difficult, and most patients are not diagnosed until a substantial degradation of cartilage has occurred as a result of the disease. This research will study the interaction between different components of articular cartilage and investigate, how this interaction can be exploited for the development of reliable and non-invasive techniques of cartilage imaging. Mobility of water molecules is a potent indicator of the microscopic structure of the cartilage scaffold. We will use this fundamental biophysical relationship to measure the internal architecture of collagen fibres; observe the changes effected by mechanical load; and distinguish between healthy and osteoarthritic cartilage.

Measuring the flushing time of waters in the Great Barrier Reef. There are concerns both in the scientific community and in the general public about the possible implications of agricultural runoff to the Great Barrier Reef (GBR). Due to this, the Great Barrier Reef Marine Park Authority has developed a "Reef Water Quality Protection Plan" (RWQPP) which may have significant economic implications to the grazing, sugar, and other primary industries. In order to protect the GBR, whilst also minimiz ....Measuring the flushing time of waters in the Great Barrier Reef. There are concerns both in the scientific community and in the general public about the possible implications of agricultural runoff to the Great Barrier Reef (GBR). Due to this, the Great Barrier Reef Marine Park Authority has developed a "Reef Water Quality Protection Plan" (RWQPP) which may have significant economic implications to the grazing, sugar, and other primary industries. In order to protect the GBR, whilst also minimizing the impacts on agricultural industries, it is important to understand the processes that affect the buildup and broad-scale dispersion of contaminants in the GBR. This project will facilitate that understanding.Read moreRead less
Contribution of surf zone wind stress to storm surge inundation. In the present era of climate change, storm surge forecasting is becoming an increasingly important part of disaster management planning. The responsible state and national agencies require accurate forecasting tools in order to best safeguard communities and plan infrastructure. Storm surges result from low pressure atmospheric conditions and wind forces on the ocean. However, the wind forces on the surf zone are unknown, with the ....Contribution of surf zone wind stress to storm surge inundation. In the present era of climate change, storm surge forecasting is becoming an increasingly important part of disaster management planning. The responsible state and national agencies require accurate forecasting tools in order to best safeguard communities and plan infrastructure. Storm surges result from low pressure atmospheric conditions and wind forces on the ocean. However, the wind forces on the surf zone are unknown, with the result that inaccurate warnings are issued to communities. This project will lead to significant improvements in forecast accuracy by providing this missing data and by developing new models for the surf zone wind forcing. Read moreRead less
Tropical sand beach ridges - a new approach to palaeotempestology. Investigations of sand beach ridges in northern Australia will considerably reduce the impact of future tropical cyclones on communities. These ridges record a detailed history of cyclones over the past 5,000 years. Due to the great length of record we will now be able to identify cycles of cyclone activity, which will allow us to better predict the consequences of these hazards under an enhanced greenhouse climate and reduce the ....Tropical sand beach ridges - a new approach to palaeotempestology.
