Stroke is a chronic disease of increasing prevalence with increasing age. There is a critical need to develop more effective treatments of communication disorders in this population. One way of achieving this is to combine certain drugs with language therapy. Through studying how these drugs influence language, this research will provide vital knowledge for developing effective forms of pharmacotherapy for adults with language disorders after brain injury. More effective language rehabilitation can have direct positive consequences on the ability to regain and maintain employment and social relationships after stroke or brain injury and will address the large and growing social and economic cost to the nation.Read moreRead less
A functional imaging study of semantic processing modulated by dopamine. The role of dopamine in language processing is largely unknown, despite emerging evidence that dopaminergic alterations can modulate language in schizophrenia, Parkinson's disease, and healthy individuals. The research aims to reveal the neural and behavioural correlates of dopaminergic modulation of semantic processing using neuroimaging in healthy individuals who have ingested levodopa. It is hypothesised that levodopa wi ....A functional imaging study of semantic processing modulated by dopamine. The role of dopamine in language processing is largely unknown, despite emerging evidence that dopaminergic alterations can modulate language in schizophrenia, Parkinson's disease, and healthy individuals. The research aims to reveal the neural and behavioural correlates of dopaminergic modulation of semantic processing using neuroimaging in healthy individuals who have ingested levodopa. It is hypothesised that levodopa will modulate brain activity under circumstances where there is heightened semantic competition, consistent with a contemporary theory of dopaminergic cognitive control. The expected outcome of the research is an increased understanding of the interactions between dopamine, the language faculty, and associated neural systems.Read moreRead less
Promoting resilience in employees working in high-stress occupations. Promoting positive mental health in the workplace has been identified as a national research priority. Mental health problems such as depression and stress now give rise to social and economic burdens comparable to those due to physiological conditions such as heart disease. Prevention strategies are strongly endorsed by both Government and peak health bodies as a necessity if this burden is to be addressed. Effective workpl ....Promoting resilience in employees working in high-stress occupations. Promoting positive mental health in the workplace has been identified as a national research priority. Mental health problems such as depression and stress now give rise to social and economic burdens comparable to those due to physiological conditions such as heart disease. Prevention strategies are strongly endorsed by both Government and peak health bodies as a necessity if this burden is to be addressed. Effective workplace strategies for positive mental health promotion will greatly reduce burdens on the health care system and the community whilst increasing productivity in the workplace and quality of life for individuals and their families.Read moreRead less
An empirical evaluation of an innovative occupational stress intervention to improve the health and retention of high-risk employees. Occupational stress costs Australian organisations $105.5m, accounts for 6.5% of workplace injuries and 18.4 weeks absenteeism, per annum. This project introduces an occupational stress intervention in a State Government Department to improve the health and retention of employees who have experienced stress or who are a high risk for submitting a stress claim. The ....An empirical evaluation of an innovative occupational stress intervention to improve the health and retention of high-risk employees. Occupational stress costs Australian organisations $105.5m, accounts for 6.5% of workplace injuries and 18.4 weeks absenteeism, per annum. This project introduces an occupational stress intervention in a State Government Department to improve the health and retention of employees who have experienced stress or who are a high risk for submitting a stress claim. The intervention will reduce occupational stress costs by 40% and will be generalisable to other public and private organisations. The project will demonstrate how Australian employers can meet their legal and ethical obligations to protect employee's psychological health, with a view to ultimately reducing the occurrence and financial consequences of occupational stress claims.Read moreRead less
The impact of light intensity during night shifts on circadian adaptation. Each year, the sleep loss and body clock disruption caused by night work cost the Australian economy $2–3 billion in lost productivity, impaired well-being, and poor health. Current regulations limit sequences of night shifts to a maximum of four in a row. However, recent research suggests that this blanket limit may be a well-intentioned, but ill-informed, policy. As a result, we may be inadvertently increasing, rather t ....The impact of light intensity during night shifts on circadian adaptation. Each year, the sleep loss and body clock disruption caused by night work cost the Australian economy $2–3 billion in lost productivity, impaired well-being, and poor health. Current regulations limit sequences of night shifts to a maximum of four in a row. However, recent research suggests that this blanket limit may be a well-intentioned, but ill-informed, policy. As a result, we may be inadvertently increasing, rather than reducing, work-related fatigue. This project will determine whether longer sequences of night shifts may reduce sleep loss and body clock disruption in some workplaces. The project will provide the evidence base for a more nuanced approach to fatigue regulation and a safer workplace for Australian shiftworkers. Read moreRead less
A dynamic model of work-related effort, recovery, and affective well-being. The aim of this project is to develop and test a computational model of work-related effort and recovery that explains how people recover from work demands moment-to-moment and day-to-day. Recovery is essential for well-being. Paradoxically, however, those who need to recover find it hard to put effort into recovery. The model will be tested in a series of naturalistic observational studies and controlled experiments. In ....A dynamic model of work-related effort, recovery, and affective well-being. The aim of this project is to develop and test a computational model of work-related effort and recovery that explains how people recover from work demands moment-to-moment and day-to-day. Recovery is essential for well-being. Paradoxically, however, those who need to recover find it hard to put effort into recovery. The model will be tested in a series of naturalistic observational studies and controlled experiments. In each study, subjective and physiological experiences of well-being and recovery are measured as people regulate effort during work and recovery. The result will be a unifying and general model of work recovery, that can inform when and how to intervene to improve employee well-being.Read moreRead less

The aim of the project is to examine the factors that influence the effectiveness of personnel training programs. The outcomes that will be examined include trainee satisfaction, learning, and subsequent job performance (transfer). The project will involve an annual survey of all trainees, trainers, supervisors and workplace assessors associated with the training programs being delivered as part of the Queensland Public Service Enterprise Bargain. The research program will contribute to a growing body of research examining the contribution of individual differences and environmental factors to training quality. The major practical benefit of the research will be the development of training management and audit systems that allow organizations to maximise the effectiveness of training.Read moreRead less
Heart rate variability biofeedback coaching in reducing workplace stress: laboratory and field investigations. Targeted and informed intervention in workplace stress is a vital concept in stress management, yet it is often misinformed. Using mobile heart rate monitors we are able to measure the causes and consequences of stress in a controlled and natural environment and design specific biofeedback interventions to attack primary sources of employee strain.
A multi-level approach to the management of demands and resources to minimise the risk of psychosocial injury in the workplace. This project aims to identify ways supervisors can effectively manage workplace stress experienced by team members. Expected outcomes include better management of workplace stress and reduction in the number of employees suffering from the stress-induced ill-health, thereby reducing workers' compensation claims for stress and lowering costs.
Supervisor strategies for managing employee stress and strain: a national approach to psychosocial risk management. This research aims to identify supervisor strategies for managing occupational stress in their work teams. Expected outcomes include reduction in the number of employees reporting that they are exposed to stress and suffering from the effects of ill-health, thereby reducing workers' compensation claims for stress and lowering associated costs.
