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
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.
Assessing absolute sustainability of global cities. The project aims to create a quantitative modelling framework for assessing the absolute sustainability of cities by combining global multi-region input-output analysis with the 'safe and just space' concept for human development. The model will allow assessment of the full supply chain environmental and social impacts of urban economic activities against biophysical planetary limits as well as social foundation thresholds defined in the litera ....Assessing absolute sustainability of global cities. The project aims to create a quantitative modelling framework for assessing the absolute sustainability of cities by combining global multi-region input-output analysis with the 'safe and just space' concept for human development. The model will allow assessment of the full supply chain environmental and social impacts of urban economic activities against biophysical planetary limits as well as social foundation thresholds defined in the literature. The project will advance sustainability science methodology and will greatly benefit worldwide initiatives for urban sustainability. Case studies on Australian cities will assess where interventions can be most practically, realistically and effectively implemented.Read moreRead less
Sustainable Australian food production within secure global supply chains. This project aims at exploring future pathways for the Australian food system to remain secure under future disruptive changes, environmentally and socially sustainable, and able to offer healthy food choices. It will reveal the connections among food supply chains, diets and human health, and portray a food system that achieves public health and sustainability goals while positioning Australia securely into the global su ....Sustainable Australian food production within secure global supply chains. This project aims at exploring future pathways for the Australian food system to remain secure under future disruptive changes, environmentally and socially sustainable, and able to offer healthy food choices. It will reveal the connections among food supply chains, diets and human health, and portray a food system that achieves public health and sustainability goals while positioning Australia securely into the global supply chain network. These goals will be achieved by creating the Australian Food Lab, which will provide a collaborative research platform for environmental scientists, economists, public health experts, and food industry representatives for investigating issues pertaining to the future of our food system.Read moreRead less
PhD ASSESSMENT: AN INVESTIGATION OF EXAMINATION PROCESS, EXAMINER CONSISTENCY AND FACTORS THAT IDENTIFY THESIS QUALITY ACROSS DISCIPLINES. Doctoral research is a significant component of research activity in Australian higher education and effective research student supervision and high quality research are key goals. The main control over quality is the thesis examination, but there is no systematic study of examiner consistency or application of standards within and across disciplines. Drawing ....PhD ASSESSMENT: AN INVESTIGATION OF EXAMINATION PROCESS, EXAMINER CONSISTENCY AND FACTORS THAT IDENTIFY THESIS QUALITY ACROSS DISCIPLINES. Doctoral research is a significant component of research activity in Australian higher education and effective research student supervision and high quality research are key goals. The main control over quality is the thesis examination, but there is no systematic study of examiner consistency or application of standards within and across disciplines. Drawing on candidature history, examiner reports and ratings, this cross-institutional study responds to the need for foundational research into the area. The study will ascertain assessment processes, assessment criteria and factors that identify highly rated theses. The ultimate aim is to improve the quality of doctoral education practices.Read moreRead less
Modern statistical methods for clustering community ecology data. This project will develop statistical methods and software for clustering community ecology data, and use them to analyse systematic survey and citizen science program data collected along the Great Barrier Reef. By doing so, the project will address the dearth of statistical classification techniques for high-dimensional, multi-response data with complex relationships. When the resultant clustering methods are used to construct b ....Modern statistical methods for clustering community ecology data. This project will develop statistical methods and software for clustering community ecology data, and use them to analyse systematic survey and citizen science program data collected along the Great Barrier Reef. By doing so, the project will address the dearth of statistical classification techniques for high-dimensional, multi-response data with complex relationships. When the resultant clustering methods are used to construct bioregions and characterise species’ environmental responses, they should significantly enhance evaluations of the impact of human activity and environmental change on coral diversity. Ultimately, these evaluations can underpin future decisions in the conservation and management of the Great Barrier Reef.Read moreRead less
Development of a mechanistic model of marine biological activity. The development of predictive models of marine biological activity lags that in physical oceanography. While modellers of ocean circulation use primarily physical laws, biological processes have typically been modelled using empirical approximations. Many biological processes in the ocean, however, are constrained by quantifiable biophysical limits. This study aims to improve our ability to predict the dynamics of biological po ....Development of a mechanistic model of marine biological activity. The development of predictive models of marine biological activity lags that in physical oceanography. While modellers of ocean circulation use primarily physical laws, biological processes have typically been modelled using empirical approximations. Many biological processes in the ocean, however, are constrained by quantifiable biophysical limits. This study aims to improve our ability to predict the dynamics of biological populations in the marine environment by the development of a model based on mechanistic descriptions of organisms interacting with their environment. The model's performance will be assessed by its ability to predict in situ and remotely sensed data from Australian waters.Read moreRead less

Australia seeks to be a world leader in research activity including research education and training. This is evident in the establishment of National Research Priorities, the Research Quality Framework and $577m currently invested annually in research training. Thesis quality is a critical indicator of success, but universities globally have been grappling with ways to discriminate fairly and effectively between different levels and types of research theses. This study rises to the challenge and will lead in building, refining and testing a framework for reporting thesis quality that will enhance our own system of research training and model best practice internationally.Read moreRead less
Influences of metacognitive beliefs on success in PhD candidature. In a knowledge-fuelled world our dependence on professionals is acute.

In a knowledge-fuelled world our dependence on professionals is acute. There is an imperative to gain fundamental information about how adult learners approach and surmount obstacles to learning in complex situations. Persistence of major gaps in our knowledge about professional learning is a concern particularly in high stakes research degrees such as the PhD. Drawing on candidates from Australia and overseas this project will shed light on what until now have been the 'invisible processes' that have led to the visible results of both successful and problematic doctoral candidature. The findings will provide direction for stakeholders, impact on global debates about doctoral quality, and enhance research capacity.Read moreRead less
