Diversifying Ethnicity In Australia's Population And Environment Debates, Natascha Klocker, Lesley Head
Diversifying Ethnicity In Australia's Population And Environment Debates, Natascha Klocker, Lesley Head
Natascha Klocker
Population–environment debates in Australia are at an impasse. While the ability of this continent to sustain more migrants has attracted persistent scrutiny, nuanced explorations of diverse migrant cultures and their engagements with Australian landscapes have scarcely begun. Yet as we face the challenges of a climate changing world we would undoubtedly benefit from the most varied knowledges we can muster. This paper brings together three arenas of environmental debate circulating in Australia—the immigration/carrying capacity debate, comparisons between Indigenous and Anglo-European modes of environmental interaction, and research on household sustainability dilemmas—to demonstrate the exclusionary tendencies of each. We then attempt to …
Twisted Cyclic Theory, Equivariant Kk-Theory And Kms States, Alan L. Carey, Sergey Neshveyev, R Nest, Adam Rennie
Twisted Cyclic Theory, Equivariant Kk-Theory And Kms States, Alan L. Carey, Sergey Neshveyev, R Nest, Adam Rennie
Associate Professor Adam Rennie
Given a C-algebra A with a KMS weight for a circle action, we construct and compute a secondary invariant on the equivariant K-theory of the mapping cone of AT ,! A, both in terms of equivariant KK-theory and in terms of a semifinite spectral flow. This in particular puts the previously considered examples of Cuntz algebras [10] and SUqð2Þ [14] in a general framework. As a new example we consider the Araki-Woods IIIl representations of the Fermion algebra.
Just Add Water: Colonisation, Water Governance, And The Australian Inland, Leah M. Gibbs
Just Add Water: Colonisation, Water Governance, And The Australian Inland, Leah M. Gibbs
Leah Maree Gibbs
Water has played a key role in the development of the Australian inland and the nation. For European colonists, the dry and variable landscape challenged ideas about nature imported from northern temperate regions. I argue first, that colonists brought with them ideas for ordering nature and tools for transforming landscapes that led to inappropriate and destructive water management and the silencing of local voices and knowledge systems. Secondly, colonial patterns of ordering and transforming landscapes are ongoing, but new ways of governing water, which challenge colonialism, are emerging. In the first section of the paper I discuss colonial relationships with …
Development And Validation Of A Concept Inventory For Introductory-Level Climate Change Science, Lorna Jarrett, Brian Ferry, George Takacs
Development And Validation Of A Concept Inventory For Introductory-Level Climate Change Science, Lorna Jarrett, Brian Ferry, George Takacs
George Takacs
This paper follows on from Jarrett, Takacs and Ferry (2011) which reported the first stage in development of a high school level concept inventory (CI) for the science of climate change: the climate change concept inventory (CCCI). In order to develop a reliable and valid instrument, it is necessary to follow appropriate procedures. This paper details the process of CI item development; reports statistical results of initial field trials and outlines how these will be used to further refine the CCCI. Item difficulty, discrimination, and point biserial coefficient were calculated for each item. Cronbach's alpha and test-retest data were used …
Living Together But Apart: Material Geographies Of Everyday Sustainability In Extended Family Households, Natascha Klocker, Chris Gibson, Erin Borger
Living Together But Apart: Material Geographies Of Everyday Sustainability In Extended Family Households, Natascha Klocker, Chris Gibson, Erin Borger
Natascha Klocker
In the Industrialized West, ageing populations and cultural diversity-combined with rising property prices and extensive years spent in education-have been recognized as diverse factors driving increases in extended family living. At the same time, there is growing awareness that household size is inversely related to per capita resource consumption patterns, and that urgent problems of environmental sustainability are negotiated, on a day-to-day basis (and often unconsciously), at the household level. This paper explores the sustainability implications of everyday decisions to fashion, consume, and share resources around the home, through the lens of extended family households. Through interviews with extended family …
Conducting Sensitive Research In The Present And Past Tense: Recounting The Stories Of Current And Former Child Domestic Workers, Natascha Klocker
Conducting Sensitive Research In The Present And Past Tense: Recounting The Stories Of Current And Former Child Domestic Workers, Natascha Klocker
Natascha Klocker
In recent years, scholarship on children's work has increasingly incorporated the perspectives of working children. Although laudable, this shift toward children's inclusion in research has concentrated on those employed at the time of data collection. Former child workers have largely been overlooked as a source of information. This paper reflects on research conducted with current and former child domestic workers in Tanzania. The child domestic working experiences reported by those two groups diverged markedly: those who had already ceased employment reported far higher rates of dissatisfaction with child domestic work, and far more experiences of exploitation and abuse, than those …
Becoming Differently Modern: Geographic Contributions To A Generative Climate Politics, Lesley M. Head, Christopher R. Gibson
Becoming Differently Modern: Geographic Contributions To A Generative Climate Politics, Lesley M. Head, Christopher R. Gibson
Lesley Head
Anthropogenic climate change is a quintessentially modern problem in its historical origins and discursive framing, but how well does modernist thinking provide us with the tools to solve the problems it created? On one hand even though anthropogenic climate change is argued to be a problem of human origins, solutions to which will require human actions and engagements, modernity separates people from climate change in a number of ways. On the other, while amodern or more-than-human concepts of multiple and relational agency are more consistent with the empirical evidence of humans being deeply embedded in earth surface processes, these approaches …
Decentring 1788: Beyond Biotic Nativeness, Lesley M. Head
Decentring 1788: Beyond Biotic Nativeness, Lesley M. Head
Lesley Head
The usefulness of the concept of biotic nativeness has been challenged in both the social and natural sciences, for different reasons. This paper explores the particular construction of nativeness in Australia in relation to plants, showing that the definition builds on and inscribes more deeply the boundary between humans and the rest of nature seen in the wider literature. In this context two further boundaries are etched: between some humans and others, and before and after European colonisation. Such a use of nativeness as an axiom of environmental management is argued to be problematic, foreclosing a number of future options …
Online Advertising: Examining The Content And Messages Within Websites Targeted At Children, Lisa Kervin, Sandra Jones, Jessica Mantei
Online Advertising: Examining The Content And Messages Within Websites Targeted At Children, Lisa Kervin, Sandra Jones, Jessica Mantei
Jessica Mantei
It is recognised that from a young age children spend considerable portions of their leisure time on the Internet. In Australia a number of child-targeted magazines have associated websites, which have high and ever-increasing readership. We do not yet know the impact of this medium upon children. Overt advertising is evident on webpages, but so too are hidden advertisements in the written text, images and games. This material usually does not comply with existing broadcasting codes of practice for mainstream advertising. This article examines the instances of overt and covert advertisements for food within three websites monitored over a 12-month …
I Was Only Nineteen, 45 Years Ago: What Can We Learn From Australia's Conscription Lotteries?, Peter Siminski, Simon Ville
I Was Only Nineteen, 45 Years Ago: What Can We Learn From Australia's Conscription Lotteries?, Peter Siminski, Simon Ville
Simon Ville
The Australian conscription lotteries of 1965-1972 are a unique and underutilised resource for studying the effects of army service and veterans’ programs. Drawing on many data sources and 25 years of related US literature, we present a comprehensive analysis of this natural experiment, examining indicators of health, personal economic outcomes, family outcomes and educational attainment. We discuss the numerous potential mechanisms involved and the limitations of available data.

Does The Interest Rate For Business Loans Respond Asymmetrically To Changes In The Cash Rate?, Abbas Valadkhani, Amir Arjomandi, Martin J. O'Brien
Does The Interest Rate For Business Loans Respond Asymmetrically To Changes In The Cash Rate?, Abbas Valadkhani, Amir Arjomandi, Martin J. O'Brien
Faculty of Commerce - Papers (Archive)
This article examines the dynamic relationship between the Reserve Bank of Australia's (RBA's) cash rate and the variable interest rate for lending to small businesses. The relationship is evaluated via an asymmetric GARCH model using monthly data spanning from August 1990 to October 2012. Our results show that a 1 percentage point increase in the cash rate results in an instantaneous 1.086 percentage point rise in the variable rate for small businesses, whereas an equivalent 1 percentage point cut only leads to a 0.862 percentage point fall with a delay of up to 2 months. This outcome has obvious implications …
A Cluster Randomised Trial Of A School-Based Intervention To Prevent Decline In Adolescent Physical Activity Levels: Study Protocol For The 'Physical Activity 4 Everyone' Trial, Rachel Sutherland, Elizabeth Campbell, David R.

A Cluster Randomised Trial Of A School-Based Intervention To Prevent Decline In Adolescent Physical Activity Levels: Study Protocol For The 'Physical Activity 4 Everyone' Trial, Rachel Sutherland, Elizabeth Campbell, David R. Lubans, Philip J. Morgan, Anthony D. Okely, Nicole Nathan, Luke Wolfenden, Jannah Jones, Lynda Davies, Karen Gillham, John Wiggers
Faculty of Social Sciences - Papers (Archive)
Background: Adolescence is an established period of physical activity decline. Multi-component school-based interventions have the potential to slow the decline in adolescents' physical activity; however, few interventions have been conducted in schools located in low-income or disadvantaged communities. This study aims to assess the effectiveness of a multi-component school-based intervention in reducing the decline in physical activity among students attending secondary schools located in disadvantaged communities. Methods/Design: The cluster randomised trial will be conducted with 10 secondary schools located in selected regions of New South Wales, Australia. The schools will be selected from areas that have a level of socio-economic …
Pricing Parisian And Parasian Options Analytically, Song-Ping Zhu, Wen-Ting Chen
Pricing Parisian And Parasian Options Analytically, Song-Ping Zhu, Wen-Ting Chen
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, two analytic solutions for the valuation of European-style Parisian and Par. asian options under the Black-Scholes framework are, respectively, presented. A key feature of our solution procedure is the reduction of a three-dimensional problem to a two-dimensional problem through a coordinate transform designed to combine the two time derivatives into one. Compared with some previous analytical solutions, which still require a numerical inversion of Laplace transform, our solutions, written in terms of double integral for the case of Parisian options but multiple integrals for the case of Par. asian options, are both of explicit form; numerical evaluation …
Unstable Willmore Surfaces Of Revolution Subject To Natural Boundary Conditions, Anna Dall'acqua, Klaus Deckelnick, Glen Wheeler
Unstable Willmore Surfaces Of Revolution Subject To Natural Boundary Conditions, Anna Dall'acqua, Klaus Deckelnick, Glen Wheeler
Faculty of Engineering and Information Sciences - Papers: Part A
In the class of surfaces with fixed boundary, critical points of the Willmore functional are naturally found to be those solutions of the Euler-Lagrange equation where the mean curvature on the boundary vanishes. We consider the case of symmetric surfaces of revolution in the setting where there are two families of stable solutions given by the catenoids. In this paper we demonstrate the existence of a third family of solutions which are unstable critical points of the Willmore functional, and which spatially lie between the upper and lower families of catenoids. Our method does not require any kind of smallness …
Non-Collapsing In Fully Nonlinear Curvature Flows, Ben H. Andrews, Mat Langford, James A. Mccoy
Non-Collapsing In Fully Nonlinear Curvature Flows, Ben H. Andrews, Mat Langford, James A. Mccoy
Faculty of Engineering and Information Sciences - Papers: Part A
We consider embedded hypersurfaces evolving by fully nonlinear flows in which the normal speed of motion is a homogeneous degree one, concave or convex function of the principal curvatures, and prove a non-collapsing estimate: Precisely, the function which gives the curvature of the largest interior sphere touching the hy- persurface at each point is a subsolution of the linearized flow equation if the speed is concave. If the speed is convex then there is an analogous statement for exterior spheres. In particular, if the hypersurface moves with positive speed and the speed is concave in the principal curvatures, then the …
A Classification Theorem For Helfrich Surfaces, James Mccoy, Glen Wheeler
A Classification Theorem For Helfrich Surfaces, James Mccoy, Glen Wheeler
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper we study the functional W , which is the the sum of the Willmore energy, weighted surface area, and weighted volume, for surfaces immersed in R^3. This coincides with the Helfrich functional with zero `spontaneous curvature'. Our main result is a complete classification of all smooth immersed critical points of the functional with nonnegative surface area weight and small L^2 norm of tracefree curvature. In particular we prove the non-existence of critical points of the functional for which the surface area and enclosed volume are positively weighted.
Does Health Capital Have Differential Effects On Economic Growth?, Arusha V. Cooray
Does Health Capital Have Differential Effects On Economic Growth?, Arusha V. Cooray
Faculty of Commerce - Papers (Archive)
Investigating the impact of health capital disaggregated by gender on economic growth in a sample of 210 countries over the 1990-2008 period, this study suggests that the influence of health capital across countries cannot be generalised. Results for the full sample indicate that health capital does not have a robust and significant effect on economic growth unless through their interactions with health expenditure and education. The results disaggregated by income group reveal that health capital has a positive robust influence on economic growth in high and upper middle income economies. In low and low middle income economies, health capital gains …
Gifts, Sustainable Consumption And Giving Up Green Anxieties At Christmas, Carol Farbotko, Lesley Head
Gifts, Sustainable Consumption And Giving Up Green Anxieties At Christmas, Carol Farbotko, Lesley Head
Faculty of Science, Medicine and Health - Papers: part A
This paper explores the proposition that gifting is a little recognised yet important practice bound up in the quest for sustainable consumption, which has largely been studied with reference to market rather than gift economies. It draws on gift theories in economic anthropology which explain gifts as engendering social relations of reciprocity and beyond, and shaping social life differently to commodities. Understanding how and why commodities become gifts (and vice versa), we contend, provides a new way of understanding some of the complex ways in which social relations are implicated in sustainable consumption. We use a study of Christmas gifting …
