Summary
Groundbreaking Australian research shows that sitting for too long, which is routine for most office workers, contributes to overweight and to a greater risk of developing diabetes and heart disease. In over 300 desk-bound office workers, this world-first study will assess the effectiveness of an innovative workplace program aimed at reducing and breaking up sitting time. It will identify practical ways for Australian office workers to minimise unhealthy effects of sitting too much at work.
The Implementation of Process Regulation in Occupational Health and Safety: A Comparative Study of Policy and Practice. The shift from prescriptive to process regulation of occupational health and safety (OHS) over the past 25 years represents the most significant transformation of OHS law since the nineteenth century. OHS regulators hoped process standards would provide a comprehensive and adaptable regulatory framework to address hazards at work. Yet the implementation and enforcement of proce ....The Implementation of Process Regulation in Occupational Health and Safety: A Comparative Study of Policy and Practice. The shift from prescriptive to process regulation of occupational health and safety (OHS) over the past 25 years represents the most significant transformation of OHS law since the nineteenth century. OHS regulators hoped process standards would provide a comprehensive and adaptable regulatory framework to address hazards at work. Yet the implementation and enforcement of process standards and systematic OHS management has been little researched. This project will analyse the development and implementation of process standards in six jurisdictions, assessing their evolution, effectiveness and ability to meet changing workplace circumstances. It will provide knowledge and tools for improving interventions.Read moreRead less

Australia has workforce shortages and an ageing population. Physiotherapists are key players in promoting and maintaining good health through their leadership in physical activity and rehabilitation to retain Australians in the workforce and to ensure quality of life for our ageing population. There is a national shortage of physiotherapists. Increasing numbers of physiotherapists are being trained, requiring new models of clinical training as there is no capacity in conventional training to cope with student numbers. This research will develop and evaluate new models of training incorporating standardised patients (actors) and simulators (mannequins) which increase education capacity. Models are transferable to other health professions.Read moreRead less
Excessive sitting and population health: strengthening the science and the relevance to policy and practice. The majority of Australian adults spend most of their waking hours sitting; this increases the likelihood of developing diseases of inactivity, including diabetes, heart disease and some cancers. New research will investigate what factors encourage excessive sitting and what the health benefits are for people who deliberately do less sitting.
Understanding and Managing the Occupational Health Impacts on Investigators of Internet Child Exploitation. Through developing best practice models for managing vicarious trauma in investigators of Internet child exploitation, the project will result in enhanced job satisfaction and less burnout of workers, and reduced health costs for policing organisations.

Through developing best practice models for managing vicarious trauma in investigators of Internet child exploitation, the project will result in enhanced job satisfaction and less burnout of workers, and reduced health costs for policing organisations. Thus the project addresses a serious occupational health issue and contributes to the goal of promoting and maintaining good health. Further, by better managing the occupational health of investigators, the project will enhance the capacity of police organisations to deliver on their mission of investigating and preventing Internet child exploitation. This in turn contributes to the reduced consumption of Internet child exploitation and the associated traumatisation of abused victims. 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.

Summary
Metal ions such as iron and copper have been reproted to be present in the lesions present in diseased human arteries and it has been suggested that these metal ions contribute to the development of atherosclerosis (hardening of the arteries) via their ability to catalyse the formation of highly reactive molecualr fragments called free radicals.

Though metal ions are known to catalyse such reactions in test-tube experiments, both the presence of metal ions in diseased arteries and their ability to generate free radicals is controversial. This study will employ a novel, minimally-invasive, technique to assess the nature and quantity of metal ions present in well-defined human and animal lesions at different stages of lesion development. The ability of these metal ions to catalyse free radical formation from components present in the artery wall will also be assessed. The release of these metal ions from the artery wall to added organic molecules will be assessed as this might minimise their potential to cause damage, and provide a possible therapeutic strategy. These studies will therefore provide valuable information as to the significance and role of reactive metal ions in the development of human artery disease and the possible prevention, or minimisation, of such processes.Read moreRead less

Summary
Friedreich's ataxia (FA) is due to the lack of a protein known as frataxin. A variety of studies using Baker's yeast and conditional frataxin knockout (KO) mice have shown that deletion of frataxin leads to the accumulation of toxic iron in their mitochondrion. More recently, a variety of studies have shown that FA patients have iron-loading within their mitochondrion.

A variety of studies using Baker's yeast and conditional frataxin knockout (KO) mice have shown that deletion of frataxin leads to the accumulation of toxic iron in their mitochondrion. More recently, a variety of studies have shown that FA patients have iron-loading within their mitochondrion. Iron in the highly redox active environment of the mitochondrion could contribute to the generation of cytotoxic radicals that cause severe damage. Further, cells deficient in frataxin are sensitive to oxidant stress and Fe chelators rescue oxidant-mediated death of cells from FA patients. Indeed, free radical scavengers have shown to be of use in the treatment of this disease. Studies in DR's lab during this NHMRC grant have shown that frataxin is down-regulated by erythroid differentiation or the haem precursor, protoporphyrin IX (BLOOD 2002;99:3813-22). These data indicate a role for frataxin in Fe metabolism and the pathogenesis of FA. In this study we will continue to examine the role of frataxin in the way cells handle Fe using experimental models developed under the current NHMRC grant. These include transfected cell lines with low frataxin expression generated using an expression vector containing anti-sense frataxin cDNA. Further we obtained the frataxin conditional KO mouse and generated a breeding colony. These animals display many of the pathological features of FA and are the best current model of the disease. Indeed, they will be critical for assessing the role of frataxin in Fe metabolism and as a model to test the ability of Fe-binding drugs to prevent the pathology observed. We designed lipid-soluble chelators that can enter the mitochondrion to bind Fe (Biochim Biophys Acta 2001;1536:133-140) and these ligands will be tested to prevent disease progression in the KO mice. This exciting research is crucial for understanding the pathogenesis of FA and in creating new therapies.Read moreRead less
