The HPA-axis as a marker for disruptive behaviour disorder subtypes in toddlers. Emerging neurobiological models of antisocial behaviour emphasise the role of the hypothalamic-pituitary-adrenal (HPA) axis in the onset of disruptive behaviour disorders (DBDs). Given the broad consensus that antisocial trajectories originate in the toddler years, this project will use cortisol measures of HPA-axis activity to identify the mechanisms through which developmental factors interact with parenting and ....The HPA-axis as a marker for disruptive behaviour disorder subtypes in toddlers. Emerging neurobiological models of antisocial behaviour emphasise the role of the hypothalamic-pituitary-adrenal (HPA) axis in the onset of disruptive behaviour disorders (DBDs). Given the broad consensus that antisocial trajectories originate in the toddler years, this project will use cortisol measures of HPA-axis activity to identify the mechanisms through which developmental factors interact with parenting and family environment to shape persistent DBDs; this will be achieved by following toddlers with severe DBDs across a controlled trial of a parenting intervention.Read moreRead less

This project will benefit Australia from several perspectives. It will make an important contribution to understanding limitations to peripheral vision of the eye, particularly as a result of refractive surgical intervention. This is important because many Australians will require such surgery. Being able to better measure and correct peripheral aberrations will lead to improved imaging of the eye and thus contribute to improved detection and diagnosis of ophthalmic disease. The study will benefit ophthalmologists, optometrists, and engineers involved in designing visual instruments. This project will provide training in adaptive optics for graduate students not available in any other Australian institution.Read moreRead less
Investigation of the component distributions of pause duration in spontaneous speech: Constraints for models of language production. We have discovered that the distribution of pause durations in spontaneous speech of individual speakers can be decomposed into at least two log-normal distributions. Our project will investigate this finding and provide a foundation for new research relevant to language production models. This will be achieved by determining the semantic, lexical, psycholinguistic ....Investigation of the component distributions of pause duration in spontaneous speech: Constraints for models of language production. We have discovered that the distribution of pause durations in spontaneous speech of individual speakers can be decomposed into at least two log-normal distributions. Our project will investigate this finding and provide a foundation for new research relevant to language production models. This will be achieved by determining the semantic, lexical, psycholinguistic, physiological, and acoustic concomitants of each component distribution and by investigating the impact of selected variables on the shape and location of each. The project has important implications for models of language production and applied problems involving automatic speech recognition, forensic speaker identification, and human communication disorders.Read moreRead less
Identifying tear lipids, their deposition onto contact lenses and their role in the development of dry eye. Lipids provide a critical layer in the human tear film that retards evaporation and helps nourish and protect the eye. We will identify the molecules within this essential "oil slick" to better understand dry eye syndrome and the discomfort associated with wearing contact lenses. This may lead to new treatments for dry eye and novel technologies that provide greater comfort for the ~120,00 ....Identifying tear lipids, their deposition onto contact lenses and their role in the development of dry eye. Lipids provide a critical layer in the human tear film that retards evaporation and helps nourish and protect the eye. We will identify the molecules within this essential "oil slick" to better understand dry eye syndrome and the discomfort associated with wearing contact lenses. This may lead to new treatments for dry eye and novel technologies that provide greater comfort for the ~120,000 Australians who wear contact lenses. This collaborative research directly supports the mission of a respected non-profit organisation (Institute for Eye Research) and will train scientists in world-leading analytical technologies that are essential to Australia's emerging biotechnology industries.Read moreRead less
Detection and Quantification of General Fetal Movements from Accelerometer Measurements using Nonstationary Signal Processing Techniques. There are approximately 1,750 fetal deaths per year in Australian with about one-third occurring late in gestation and without an apparent cause. The development of an automated system capable of long-term monitoring of fetal health will result in accurate diagnoses and prediction of future outcome. This will, in turn, allow early intervention by the clinicia ....Detection and Quantification of General Fetal Movements from Accelerometer Measurements using Nonstationary Signal Processing Techniques. There are approximately 1,750 fetal deaths per year in Australian with about one-third occurring late in gestation and without an apparent cause. The development of an automated system capable of long-term monitoring of fetal health will result in accurate diagnoses and prediction of future outcome. This will, in turn, allow early intervention by the clinician to reduce fetal deaths and enhance the chances of good outcomes with resultant savings in social and financial costs to the community. The development of such equipment would spawn future research into intervention treatments and contribute to Australia's position as a world leader in computerised health monitoring systems.Read moreRead less

Design of Neonatal Seizure Diagnosis Methods Using Time-Frequency Signal Processing Techniques. Seizures occur in approximately 0.5% of all newborns. They are often the only indicator of an early dysfunction in central nervous system (CNS). Their occurrence raises concerns about the underlying cause, its effect on the brain, and the appropriate treatment. Newborn seizures are mostly sub-clinical and only detected through the Electroencephalogram. For an efficient diagnosis, seizure classificatio ....Design of Neonatal Seizure Diagnosis Methods Using Time-Frequency Signal Processing Techniques. Seizures occur in approximately 0.5% of all newborns. They are often the only indicator of an early dysfunction in central nervous system (CNS). Their occurrence raises concerns about the underlying cause, its effect on the brain, and the appropriate treatment. Newborn seizures are mostly sub-clinical and only detected through the Electroencephalogram. For an efficient diagnosis, seizure classification systems were proposed based on visual observations. This project proposes developing a novel approach to automate the classification process using time-frequency (TF) signal processing techniques based on the multi-channel characteristics of the seizure; namely: A) TF signature B) origin, and C) propagation behaviour.Read moreRead less

The main aim of this study is to validate a set of biological and psychological prognostic indicators of outcome following whiplash injury that we have previously identified in a single centre prospective cohort. Validation will be in the context of a large multicentre international cohort. This will allow stakeholders involved in whiplash such as health care and insurance providers to predict with confidence both those persons at risk of developing chronic symptoms as well as those with a good chance of full recovery. Furthermore the validation of the predictive capacity of these indicators will, for the first time, provide predictive markers that are amenable to specific early multiprofessional treatment interventions.Read moreRead less
