Summary
Adolescence is a critical period for the establishment of adult drug use behaviours. If smoking does not commence in teenage years it is unlikely to occur. This innovative project not only continues to address tobacco control with this important age group but also builds on evidence from a randomised intervention trial involving over 4,000 Year 9 students tracked over two years. This project was called the Smoking Cessation for Youth Project (SCYP). Preliminary longitudinal analyses of the SCYP ....Adolescence is a critical period for the establishment of adult drug use behaviours. If smoking does not commence in teenage years it is unlikely to occur. This innovative project not only continues to address tobacco control with this important age group but also builds on evidence from a randomised intervention trial involving over 4,000 Year 9 students tracked over two years. This project was called the Smoking Cessation for Youth Project (SCYP). Preliminary longitudinal analyses of the SCYP data indicate that the intervention students were significantly less likely to smoke heavily (smoking five or more days per week) than the control group and that intervention students were also significantly less likely to have tried smoking than the control group. These results represent a world first in evidence that population-based smoking cessation interventions among teenagers can be successful. The proposed project will determine the extent to which these positive intervention effects are sustainable, two years post intervention, as our cohort moves into Year 12. In addition to tracking the possible decay of SCYP intervention effects, the proposed project will also measure the effects of a booster intervention delivered students when they are in Year 12 (2002). The Year 12 intervention will comprise an innovative self-help 'magazine style' booster and a supportive environmental intervention involving school nurses and local GPs. This proposal represents a cost-effective opportunity to measure the effectiveness of a Year 12 tobacco cessation booster intervention. Further data on tobacco smoking behaviour in 2002 will also enable us to determine how long the SCYP intervention appears to affect behaviour and whether 'boosters' are needed in later secondary school years to maintain the benefits.Read moreRead less
Sperm Competition and Sexual Selection. Competition between the sperm of two males within a single female has had profound implications for the evolution of male reproductive biology and behaviour. However, the reasons why females should mate with more than one male and thus generate sperm competition remains an evolutionary puzzle. Few studies have examined sperm competition from the female perspective and indeed, female perspectives are currently the subject of considerable debate. Using in ....Sperm Competition and Sexual Selection. Competition between the sperm of two males within a single female has had profound implications for the evolution of male reproductive biology and behaviour. However, the reasons why females should mate with more than one male and thus generate sperm competition remains an evolutionary puzzle. Few studies have examined sperm competition from the female perspective and indeed, female perspectives are currently the subject of considerable debate. Using insects as models I will examine the benefits of sperm competition for females and thereby the selective pressures that favour multiple mating. Moreover, I will determine whether sexual selection can act after copulation.Read moreRead less

This project explores the evolutionary significance of female mating frequency for male and female reproductive biology. The research proposes to use innovative approaches to examine the evolution of ejaculate characteristics, will focus on the evolution of sperm form and function, and will examine the fitness benefits of promiscuity from the females' perspective. The research uses both vertebrates and invertebrates as model organisms to test predictions and assumptions of theoretical models relevant to both internal and external modes of fertilization. The design of this project will allow cutting-edge, theoretically informed and experimentally grounded conclusions to be drawn regarding selection under sperm competition.Read moreRead less

Ejaculate-mediated paternal effects on offspring fitness. This project aims to unravel the evolutionary importance of ejaculate-mediated paternal effects, through which paternal lifestyle factors, such as diet and exposure to toxicants, influence offspring growth and health independently of genes. By identifying the molecular mechanisms underlying these non-genetic sources of inheritance, their adaptive value, and their potential to fuel evolutionary change, the project expects to generate new k ....Ejaculate-mediated paternal effects on offspring fitness. This project aims to unravel the evolutionary importance of ejaculate-mediated paternal effects, through which paternal lifestyle factors, such as diet and exposure to toxicants, influence offspring growth and health independently of genes. By identifying the molecular mechanisms underlying these non-genetic sources of inheritance, their adaptive value, and their potential to fuel evolutionary change, the project expects to generate new knowledge that will be relevant across the biological, medical and agricultural sectors. Expected outcomes and benefits include building institutional and interdisciplinary collaborations and the development of tools to understand the evolutionary impacts of paternal lifestyle choices for offspring traits.Read moreRead less

The applicants have independently developed theoretically novel models, and this collaboration will enable them to combine and strengthen their complementary perspectives.
Much psychologically important processing, for example speech perception and spelling, requires the representation and reproduction of serial order information. Existing models account for a wide range of data and collectively represent exciting progress in the understanding of basic mechanisms of memory. Can these models be unified and reconciled? To date, detailed comparisons of models are lacking. This proposal is for the applicants to elaborate and unify their contrasting theoretical approaches.

This work will advance basic science by enhancing understanding of human coding of image structure. The aim is to provide a common structure for understanding visual processing of form, motion and position. The work will help lift the international profile of Australian science. Explaining how the primitives for shape perception are extracted will also have consequences of potential economic benefit. One important aspect is the design of displays that allow observers to absorb complex information about rapidly changing situations. This work has the potential to provide information that enables display designers to optimise the efficiency of presentation of pattern and motion information.Read moreRead less

The project examines the role of time and similarity in memory for serial order, with the long-term goal to construct a new computational model of short-term memory. The investigators are internationally known for their models, and the collaboration will enable them to combine their complementary perspectives into a unifying theory. Theory construction will be guided by two sets of studies: The first will delineate the circumstances, if any, under which temporal separation at encoding affects memory. So far, we have shown that temporal distinctiveness has no effect on memory, unless people use temporal gaps to 'chunk' the list. The second set of studies will examine whether phonological similarity determines the strength of encoding.Read moreRead less
