Towards a climate theory of tropical cyclone formation. In Earth's current climate, about 80 to 90 tropical cyclones form every year around the globe, but the reasons why cyclones form at this rate are unknown. This project will use a combination of theoretical techniques and numerical simulation to elucidate the links between large-scale climate and the rate of tropical cyclone formation. A series of climate model experiments will be performed that also have the potential to improve confidence ....Towards a climate theory of tropical cyclone formation.

This project will use a combination of theoretical techniques and numerical simulation to elucidate the links between large-scale climate and the rate of tropical cyclone formation. A series of climate model experiments will be performed that also have the potential to improve confidence in our predictions of tropical cyclone incidence in a future, changed climate.Read moreRead less
Coupling tropical cyclone and climate physics with ocean waves. It is argued that without accounting for the wave effects directly, the physics of large-scale air-sea interactions is inaccurate and incomplete. The project will introduce explicit coupling of large-scale atmospheric and oceanic phenomena with the physics of surface waves which should lead to improved predictions of tropical cyclones and climate.
Cloudiness over the Southern Ocean: reducing a key knowledge gap and source of climate model uncertainty. Southern Ocean clouds are key ingredients of the global climate system and yet are only poorly understood and poorly represented in climate models. Through the use of advanced observational analysis techniques this research will provide a deep understanding of key Southern Ocean cloud regimes and improve their representation in models.
Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aim ....Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aims to apply novel observational methods, complimented by numerical modelling, to quantify the drivers of recent change. This project expects to transform our ability to predict how ocean temperature and sea level will change in the future.Read moreRead less
Coping with temperature extremes: morphological constraints on leaf function in a warmer, drier climate. This project will determine how hydraulic properties of temperate, evergreen leaves affect their capacity to cope with seasonal variation in temperature extremes. The results will enhance mechanistic understanding of temperature tolerance, and inform prediction of vegetation change in response to climate warming and increasing CO2 concentrations.
The Aging Population, Superannuation and Corporate Dividend Policy. The project intends to examine how population wealth and age affect one important aspect of corporate decision-making, namely dividend policy. Researchers invest considerable effort in understanding how demographics impact upon the need for, and structure of, government systems including social security and taxation, but relatively little is known about its effect on capital markets or corporate decision-making. Although individ ....The Aging Population, Superannuation and Corporate Dividend Policy. The project intends to examine how population wealth and age affect one important aspect of corporate decision-making, namely dividend policy. Researchers invest considerable effort in understanding how demographics impact upon the need for, and structure of, government systems including social security and taxation, but relatively little is known about its effect on capital markets or corporate decision-making. Although individual investors are, by nature, atomistic, the project argues changes in investor preferences will ultimately prompt companies to alter their dividend policies. Pressure on firms to update these policies will come from superannuation and pension fund managers who, as fiduciaries, will invest money consistent with clients' revised preferences. The project aims to more fully characterise how Australia's ageing population will affect the public and private sectors.Read moreRead less
Australian savannah landscapes: past, present and future. Australian savannahs are productive and culturally and biologically significant landscapes but are vulnerable to climate change. The project will determine savannah function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.
Understanding climate and harvest induced changes in fish life histories. This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling. Expected outcomes include fundamental insights into how human-induced environmental change affects fish gr ....Understanding climate and harvest induced changes in fish life histories. This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling. Expected outcomes include fundamental insights into how human-induced environmental change affects fish growth and maturation, and a subsequent critical evaluation of the sensitivity of fisheries models to trends in these life-history traits. This should provide significant benefits to fisheries and ecosystem management, ensuring they remain productive and resilient in a time of rapid environmental change.Read moreRead less
Understanding the Factors which Underlie Successful Refugee Integration in the Australian Workplace. There is general agreement that more needs to be done to integrate refugees into the Australian workplace. This project aims to: identify psychological predictors that enable refugee workers to succeed in maintaining their employment and perform at a higher level; examine the importance of workplace and social support to refugee workplace integration, and the groups for which it may have the grea ....Understanding the Factors which Underlie Successful Refugee Integration in the Australian Workplace. There is general agreement that more needs to be done to integrate refugees into the Australian workplace. This project aims to: identify psychological predictors that enable refugee workers to succeed in maintaining their employment and perform at a higher level; examine the importance of workplace and social support to refugee workplace integration, and the groups for which it may have the greatest benefit; and, investigate the effectiveness of a training program as an intervention to enhance refugee job performance and retention. Results will have significant benefits for refugees, their employers and their communities, and will provide a road-map to improve integration of refugees into Australian society.Read moreRead less
Improving external validity of stated choice experiments. This project aims to deliver more accurate estimates of choice behaviour by reducing biases due to choice task complexity in surveys as well as design artefacts. Extracting 'true' preferences is challenging, not only due to possible hypothetical bias, but also due to increasingly complex choice tasks and the existence of design artefacts. This project will investigate the latter two in the context of marketing, transport, health, and envi ....Improving external validity of stated choice experiments. This project aims to deliver more accurate estimates of choice behaviour by reducing biases due to choice task complexity in surveys as well as design artefacts. Extracting 'true' preferences is challenging, not only due to possible hypothetical bias, but also due to increasingly complex choice tasks and the existence of design artefacts. This project will investigate the latter two in the context of marketing, transport, health, and environmental economics, and proposes new methodologies to extract preferences that more closely reflect true behaviour in real markets.Read moreRead less
