Testing the Flood Pulse Concept for rivers with variable flow regimes. For floodplain rivers the major unifying conceptual model linking hydrology, biogeochemistry and ecology is the Flood Pulse Concept (FPC). The model is based on rivers that have a seasonally predictable and long duration inundation of floodplain habitats. Recent reviews of the FPC indicate that the model needs to be broadened to describe the function of rivers with more variable flow regimes. This project will test some of th ....Testing the Flood Pulse Concept for rivers with variable flow regimes. For floodplain rivers the major unifying conceptual model linking hydrology, biogeochemistry and ecology is the Flood Pulse Concept (FPC). The model is based on rivers that have a seasonally predictable and long duration inundation of floodplain habitats. Recent reviews of the FPC indicate that the model needs to be broadened to describe the function of rivers with more variable flow regimes. This project will test some of the predictions of the FPC for variable dryland rivers by investigating how food webs in the channels of a floodplain reach respond to flows of different magnitude, seasonal timing and duration.Read moreRead less
Climate, Vegetation and Fire in the Australian Paleomonsoon: An investigation using paleodata synthesis, contemporary observations and model experiments. This investigation of the history and development of the Australian monsoon will provide much needed information for the prediction of future climatic changes in the Australasian region and beyond. Furthermore, our work will elucidate the impact of current north Australian fire regimes on the strength of the Australian monsoon that is so critic ....Climate, Vegetation and Fire in the Australian Paleomonsoon: An investigation using paleodata synthesis, contemporary observations and model experiments. This investigation of the history and development of the Australian monsoon will provide much needed information for the prediction of future climatic changes in the Australasian region and beyond. Furthermore, our work will elucidate the impact of current north Australian fire regimes on the strength of the Australian monsoon that is so critical to the environment and economy of the north Australian region, a region that produces wealth for Australia out of proportion to its population. The work has important policy implications for water and fire management in Northern Australia and is significant to aboriginals, pastoralists and other community groups.Read moreRead less
A new theoretical approach to pension fund economics, asset management and insurance. A new generation of sustainable pensions will be proposed, which can, in the long term, increase several times the level of pension payouts. The groundbreaking underlying theoretical approach suggests a paradigm shift and dramatic improvements in the performance of pensions and other long dated contracts in asset management and insurance.
Extreme Value Theory Approaches to Insurance in a Catastrophic Environment. Recent decades are marked by numerous significant natural (climate change) or man-made (financial crises) catastrophes, which have significantly altered the landscape of the insurance industry. These have potentially significant negative impacts on the availability and affordability of insurance, and hence on the capability and capacity of households and businesses to take risks and be competitive. This project endeavour ....Extreme Value Theory Approaches to Insurance in a Catastrophic Environment. Recent decades are marked by numerous significant natural (climate change) or man-made (financial crises) catastrophes, which have significantly altered the landscape of the insurance industry. These have potentially significant negative impacts on the availability and affordability of insurance, and hence on the capability and capacity of households and businesses to take risks and be competitive. This project endeavours to establish progressive approaches (using extreme value theory) to the challenges faced by insurance in such a catastrophic environment. They will enhance the financial stability and competitivity of the Australian economy, and further establish its global leadership in dealing with climate changes and catastrophes.Read moreRead less
A cross-national study of the relative impact of an oral component on PhD examination quality, language and practice. High quality doctoral degrees call for the most effective forms of assessment. This project investigates the role of oral examination in PhD assessment, common internationally but not in Australia, and is the first to compare the relative impact of oral and 'no oral' models on examination quality, language and practice.
Understanding how bacteria form multicellular biofilm communities on surfaces: the role of cyclic diguanylate as a potent biofilm activator. Bacteria usually exist as multicellular communities called biofilms when attached to surfaces, frequently to the detriment of the environment, industry and health. This project will explore the strategies bacteria use to switch from living as free-floating, individual cells to forming biofilms by studying how bacteria 'switch on' their biofilm genes.
MICROSCALE PLANKTON AND PARTICLE DYNAMICS: COMPARING AND CONTRASTING AUSTRALIAN AND INTERNATIONAL SEAS. Microscopic phytoplankton are the basis of ocean ecosystems, but most predictions and measurements focus on processes that occur over kilometres. Our recent work shows that definite and regular submetre seascape topography exists. This grant will test the extent to which this seascape topography is the fundamental organisational unit of marine ecosystems and the extent to which it characteris ....MICROSCALE PLANKTON AND PARTICLE DYNAMICS: COMPARING AND CONTRASTING AUSTRALIAN AND INTERNATIONAL SEAS. Microscopic phytoplankton are the basis of ocean ecosystems, but most predictions and measurements focus on processes that occur over kilometres. Our recent work shows that definite and regular submetre seascape topography exists. This grant will test the extent to which this seascape topography is the fundamental organisational unit of marine ecosystems and the extent to which it characterises Australian coastal waters and open ocean water masses. This research takes a leadership role in defining and advancing our understanding of how marine ecosystems function. The project will bring over $200 million of Japanese infrastructure to Australia for 3 years.Read moreRead less
Novel econometric techniques for dealing with point processes in high frequency financial data with applications to financial risk management. The recent global financial crisis highlighted the inherent risk involved in investing in financial assets. This project aims to develop novel statistical methods for forecasting the onset of instability in asset prices. The outcomes of this research will lead to improvements in the management of financial risk.
Understanding the Impact of Sovereign Wealth Funds on the Financial Markets. This project aims not only to reveal the impact of sovereign wealth fund (SWFs) on Australian international stock markets, but also to assess their investment behaviour. An SWF is an investment fund managed by a government or other organisation on behalf of a sovereign state. The impact of SWFs on international financial markets and their behaviour are of great importance to market participants as well as policy-makers. ....Understanding the Impact of Sovereign Wealth Funds on the Financial Markets. This project aims not only to reveal the impact of sovereign wealth fund (SWFs) on Australian international stock markets, but also to assess their investment behaviour. An SWF is an investment fund managed by a government or other organisation on behalf of a sovereign state. The impact of SWFs on international financial markets and their behaviour are of great importance to market participants as well as policy-makers. The project aims to measure the systemic risk contribution of SWFs and to analyse the anti-takeover provisions of SWFs’ target firms. In addition, the project aims to understand the relation between anti-takeover provisions and target firm value and will examine the role of SWFs as a socially responsible investor. The expected outcomes will improve our understanding of the impact of SWFs on the Australian financial markets in terms of social and economic wellbeing.Read moreRead less
Mathematical models for water management systems. The Australian community is currently talking about schemes to return water to the Murray-Darling river system to combat increased salinity and dramatically reduced river flow. Many believe that vastly improved water management policies are essential to maintain agricultural well-being in Australia. Salinity and water quality depend directly on flow rates and are also important in smaller catchments. In this study we will use statistical rainf ....Mathematical models for water management systems. The Australian community is currently talking about schemes to return water to the Murray-Darling river system to combat increased salinity and dramatically reduced river flow. Many believe that vastly improved water management policies are essential to maintain agricultural well-being in Australia. Salinity and water quality depend directly on flow rates and are also important in smaller catchments. In this study we will use statistical rainfall models and stochastic dynamic programming to find practical water management policies that minimise the risk to water supply. We will develop an interactive simulation and management tool using a modern computer graphics package.Read moreRead less
