Summary
Up to 50% of preterm infants will have one or more developmental difficulties. While medical complications are implicated in these problems, recent evidence points to the added effect of the infant's early environment. Hospitalised premature infants experience stress from necessary but painful hospital procedures, overstimulation and maternal deprivation. Evidence, largely from animal studies, suggests stressful early experience negatively affects brain development. We also know that premature i ....Up to 50% of preterm infants will have one or more developmental difficulties. While medical complications are implicated in these problems, recent evidence points to the added effect of the infant's early environment. Hospitalised premature infants experience stress from necessary but painful hospital procedures, overstimulation and maternal deprivation. Evidence, largely from animal studies, suggests stressful early experience negatively affects brain development. We also know that premature infants find it difficult to handle stress as they are highly disorganised neurobehaviourally. The primary aim of this study is to assess the effectiveness of a parent-based intervention in enhancing neurobehavioural development at two years of age in very premature infants. It is predicted that this stress-reduction intervention will also enhance medical stability,normal brain development, parent-child interaction and parental mental health. The intervention to be trialled involves intensive training of parents of very premature infants, and in the 12 weeks following birth the parents will be the change agents. A randomised controlled trial comparing intervention and control groups will be undertaken to assess the effectiveness of this intervention. Assessments of early brain and 2 year intellectual, emotional and behavioural development will provide important outcome measures. A major strength of this study is the inclusion of advanced Magnetic Resonance Imaging (MRI) technology as it enables differences in brain development between the intervention and control group to be assessed, the association between brain and neurobehavioural development to be explored, and the impact of stress on early brain development to be investigated. This intervention is relatively simple and inexpensive, and would be a valuable contribution to neonatal care if found to be effective in enhancing brain and neurobehavioural development.Read moreRead less

Attracting and sustaining engaged science and mathematics teachers. This project will examine what attracts or deters potential, future and practising teachers of the sciences and mathematics, by focusing on current teachers, school and university students in Queensland. Promises of a technological revolution and rapid economic development will be hollow if students do not study sciences and mathematics, and there are too few qualified teachers. This project will identify where to intervene in the science and mathematics teacher supply pipeline, and policy levers to attract and sustain quality teachers. The project is expected to uncover what attracts or deters teachers of science and mathematics—disciplines essential to industry innovation, a skilled workforce and productivity growth.Read moreRead less
Pathways to work engagement, wellbeing and positive teaching among mid-career teachers: The role of personal and workplace resources. Teaching is a highly demanding, yet rewarding career for many. It is also a decidedly stressful occupation associated with high burnout.

Teaching is a highly demanding, yet rewarding career for many. It is also a decidedly stressful occupation associated with high burnout. By following a large sample of teachers recruited ten years earlier into their mid-career, this project investigates the coping and motivational resources that keep them engaged, allowing them to thrive personally and professionally in different kinds of school environments, versus pathways that predict to burnout, ill-being and negative teaching behaviours. Selected subgroups who were most at risk and most positively engaged earlier in their career will be the focus of longitudinal case studies to uncover more nuanced processes promoting positive and negative pathways.Read moreRead less
Peer Rejection and the Maladaptive Social Behaviour of Children and Adolescents. Research indicates that peer rejection has serious negative effects on child and adolescent victims. However, little research has addressed the likelihood that peer rejection also has negative consequences for others in the social environment, through its instigation of maladaptive social behaviours such as bullying and ethnic prejudice. Given the incidence of the latter behaviours in primary and secondary schools, ....Peer Rejection and the Maladaptive Social Behaviour of Children and Adolescents. Research indicates that peer rejection has serious negative effects on child and adolescent victims. However, little research has addressed the likelihood that peer rejection also has negative consequences for others in the social environment, through its instigation of maladaptive social behaviours such as bullying and ethnic prejudice. Given the incidence of the latter behaviours in primary and secondary schools, the aim of this project is to conduct a program of research to test an integrative model of the impact of peer rejection on the maladaptive social behaviours of children and adolescents, with a particular focus on ethnic prejudice and bullying.Read moreRead less
Developing vehicle-based advanced warning countermeasures for driver fatigue. Driver fatigue is a major problem in Australia in terms of health, road safety and economic impact. Countermeasures to combat the influence of driver fatigue have been limited to public campaign strategies like resting every 2 hours. There has been little robust research on developing on-road countermeasures that could warn the driver of their fatigue status.

Driver fatigue is a major problem in Australia in terms of health, road safety and economic impact. Countermeasures to combat the influence of driver fatigue have been limited to public campaign strategies like resting every 2 hours. There has been little robust research on developing on-road countermeasures that could warn the driver of their fatigue status. This proposed project involves a collaboration with Compumedics Ltd, a leading medical device company, to conduct sophisticated research into developing an EEG and wheel behaviour fatigue countermeausure. We will further explore EEG and wheel behaviour patterns associated with fatigue, investigate noise control strategies, and conduct laboratory and on road field trials of the fatigue monitor. If this device is able to assess fatigue reliably and warn drivers in sufficient time to avert accidents, then substantial economic and social benefits will occur.Read moreRead less
Children's Intergroup Prejudice: The Roles of Cognitive Representations and Self-presentation. Research indicates that intergroup prejudice remains a problem in most Australian schools. For example, children as young as 5-6 years assign negative attributes to indigenous Australians and Pacific Islander children, they prefer not to play with these children, and they do not even want them living nearby. The proposed research will examine the possible basis of age effects in these attitudes. It wi ....Children's Intergroup Prejudice: The Roles of Cognitive Representations and Self-presentation. Research indicates that intergroup prejudice remains a problem in most Australian schools. For example, children as young as 5-6 years assign negative attributes to indigenous Australians and Pacific Islander children, they prefer not to play with these children, and they do not even want them living nearby. The proposed research will examine the possible basis of age effects in these attitudes. It will have a substantial national benefit because it will increase our understanding of this insidious social phenomenon and provide a basis for developing an intervention that will minimise a problem that has the potential to devastate community relations.

The current societal climate of industrialized countries such as Australia has shifted considerable over recent decades and is now one which is highly conducive to overfeeding and reduced physical activity. As a result, the incidence of obesity has risen markedly along with an associated increase in obesity-related chronic diseases such as cardiovascular disease, stroke, obstructive pulmonary disease, type II diabetes, and many types of cancers. Less is known about the psychological and behavioural sequelae of this overfeeding. Calorie restriction mimetics may not only act as a preventative intervention to help reduce the incidence and severity of these major health problems, but also impact on social behaviour.Read moreRead less
