Safe and unsafe workplace behaviour: the impact of organisational culture and climate. This APA(I) project involves a study of safety cultures of organizations and safety climates of workgroups. It will develop and trial safety interventions derived from an understanding of the normative and individual psychological contracts of safety. It is hypothesized that such contracts will impact on safety behaviors and injury rate. The project will be conducted in collaboration with Kmart and KAAL (A ....Safe and unsafe workplace behaviour: the impact of organisational culture and climate. This APA(I) project involves a study of safety cultures of organizations and safety climates of workgroups. It will develop and trial safety interventions derived from an understanding of the normative and individual psychological contracts of safety. It is hypothesized that such contracts will impact on safety behaviors and injury rate. The project will be conducted in collaboration with Kmart and KAAL (Alcoa) who experience very different levels of risk. The ultimate aim is to develop a better understanding of the complex human systems which impact on safety behaviors and injury rates in organizations.Read moreRead less
Challenging Disadvantage: The Social Outcomes of an Early Educational Intervention with the Family. Theory and observation indicate the importance of early parent-child interactions in determining the well-being of individuals in society. However, rigorous research is needed to explore whether early intervention in family life can enhance such development, particularly the proposed capacity of changed parenting roles and family interactions to interrupt the trans-generational perpetuation of so ....Challenging Disadvantage: The Social Outcomes of an Early Educational Intervention with the Family. Theory and observation indicate the importance of early parent-child interactions in determining the well-being of individuals in society. However, rigorous research is needed to explore whether early intervention in family life can enhance such development, particularly the proposed capacity of changed parenting roles and family interactions to interrupt the trans-generational perpetuation of socio-economic disadvantage. This project investigates the usefulness of an early intervention program new to Australia, the Home Instruction Program for Preschool Youngsters (HIPPY). It examines the processes of HIPPY and possible consequent mediating effects of family relationships on child development outcomes, in a disadvantaged Australian-born community in Geelong.Read moreRead less
The psychological effects of wasting in Australian jockeys. It is well known that many jockeys engage in short-term, unhealthy cycles of weight loss and gain, known as 'wasting', to maintain consistent low riding-weight. The use of saunas is specially popular, with other known practices including food avoidance, laxative abuse, ingestion of diuretics and appetite suppressants, excessive exercise and self-induced vomiting. The adverse physiological effects of 'wasting' are well documented. This i ....The psychological effects of wasting in Australian jockeys. It is well known that many jockeys engage in short-term, unhealthy cycles of weight loss and gain, known as 'wasting', to maintain consistent low riding-weight. The use of saunas is specially popular, with other known practices including food avoidance, laxative abuse, ingestion of diuretics and appetite suppressants, excessive exercise and self-induced vomiting. The adverse physiological effects of 'wasting' are well documented. This investigation seeks to explore and describe the ways in which these pathogenic forms of weight control used the jockeys effect their psychological health. The primary outcome focus of the research is the formulation of recommendations for the adoption of healthy weight management practices by Australian jockeys that promote psychological well-being.Read moreRead less
Enhancing learning capacity and academic outcomes using novel game technology in primary school children with developmental disabilities. Childhood inattention has been linked with poor academic outcomes and reduced social inclusion. In children with developmental disabilities improving poor attention skills is essential. The project aims to provide a novel and engaging evidence-based intervention program delivered as a portable, interactive game accessible in rural and urban communities.
Attentional mechanisms in the relationship between sleep disruption and academic outcomes in Australian school children. This project will assess the impact of sleep problems on attention and academic performance in primary school children. The project will investigate typically developing children and children with developmental disorders over 18 months. The research will advance knowledge of the interplay between sleep, attention and learning across development.
Body image instability, disordered eating and muscle dysmorphia. Body image is a serious public health issue. Dissatisfaction with body shape promotes disordered eating in females who fast and purge to lose weight, and muscle dysmorphia in males who over-exercise and use steroids to gain muscle. We will test the idea that these psychological disorders stem from an unstable body image. Our research will reveal the fundamental risk factors associated with disordered eating and muscle dysmorphia an ....Body image instability, disordered eating and muscle dysmorphia. Body image is a serious public health issue. Dissatisfaction with body shape promotes disordered eating in females who fast and purge to lose weight, and muscle dysmorphia in males who over-exercise and use steroids to gain muscle. We will test the idea that these psychological disorders stem from an unstable body image. Our research will reveal the fundamental risk factors associated with disordered eating and muscle dysmorphia and allow us to identify at-risk individuals on the basis of their body image instability. It will also predict patients' amenability to treatments that target body image, thereby improving outcomes for these individuals.Read moreRead less
Prospective predictors of body image attitudes and dieting beliefs during first years of school: Providing guidance for prevention. Although it is recognised that body dissatisfaction is a risk factor for the development of a wide range of mental health problems, little is known about its early development. There is a distinct increase in body dissatisfaction and dieting awareness during early school years. However, there has not been an exploration of a wide range of family, media, peer and sch ....Prospective predictors of body image attitudes and dieting beliefs during first years of school: Providing guidance for prevention. Although it is recognised that body dissatisfaction is a risk factor for the development of a wide range of mental health problems, little is known about its early development. There is a distinct increase in body dissatisfaction and dieting awareness during early school years. However, there has not been an exploration of a wide range of family, media, peer and school adaptation variables as predictors of body image and weight change behaviours in both girls and boys. This project will examine prospective predictors of body image and related variables in five to seven years old children. Findings will inform development of prevention interventions to assist parents and schools provide a positive body image and eating environment for Australian children.Read moreRead less
Addressing risk factors of overweight and obesity among adolescents in out-of-home care: The Healthy Eating and Active Living (HEAL) study. The health risk of overweight and obesity when adolescents are placed in out-of-home care has been largely ignored. This project will be the first to evaluate a healthy eating and physical activity obesity prevention/intervention program designed specifically for vulnerable and disadvantaged adolescents living in out-of-home residential care.
Concept-procedure interactions in addition and subtraction development. The research explores the possibility of different pathways to mathematical knowledge by examining how key concepts and procedures interact in the course of development. Studies 1 and 2 address early addition and subtraction concepts and problem solving in the physical world, Studies 3 - 6 focus on the effects of problem-solving practice and concept-based training and Studies 7 and 8 address children's knowledge of conceptu ....Concept-procedure interactions in addition and subtraction development. The research explores the possibility of different pathways to mathematical knowledge by examining how key concepts and procedures interact in the course of development. Studies 1 and 2 address early addition and subtraction concepts and problem solving in the physical world, Studies 3 - 6 focus on the effects of problem-solving practice and concept-based training and Studies 7 and 8 address children's knowledge of conceptually advanced problem-solving procedures. The results are expected to show that addition and subtraction concepts and procedures influence each other in different ways among children, signifying different pathways of cognitive development.Read moreRead less
The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will ....The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will be the first to comprehensively advance our understanding of the unique role of sex hormones in shaping the adolescent female brain. It will provide critical understanding of how individual differences in hormonal factors increase risk for emotional problems in females, and inform treatment strategies.Read moreRead less
