Manufacturing On The Move? Beyond The High Dollar In The Debate About Making Things In Australia - The Case Of The Australian Surfboard Industry - Ausccer Discussion Paper No. 2012/2, Andrew Warren, Chris Gibson

Faculty of Science - Papers (Archive)

In October 2011 surfboard manufacturer BASE abruptly closed its factory on the Gold Coast resulting in the direct loss of 50 jobs. A few days later, nearby D’Arcy Surfboards also announced it was shedding workers and downsizing from a state-of-the art purpose built factory into a backyard workshop. Each business exported surfboards internationally and employed some of Australia’s best known surfboard-makers. The troubles facing these workshops added to those brewing at the very same in Australia’s steel, aluminium, automotive and garment industries. With renewed public debate and media commentary on the future of manufacturing, we now face a crisis in …

Are Parents' Working Patterns Associated With Their Child's Sleep? An Analysis Of Dual-Parent Families In Australia, Christopher A. Magee, Peter Caputi, Don C. Iverson

Faculty of Health and Behavioural Sciences - Papers (Archive)

Insufficient sleep in children predicts emotional and behavioral problems, poorer school performance, and health problems. Child sleep durations have declined in recent decades, suggesting a need to identify and understand predictors of short sleep. The present study investigated whether aspects of parental employment (i.e. parental work hours, and non-standard work hours) were associated with sleep in children. Data collected from 2477 children aged 6–7 years as part of the Longitudinal Study of Australian Children were used in this paper. Child sleep duration, bedtimes, and wake times were determined from parent self-report using time-use diaries. Parents completed a survey assessing their …

A Comparison Of Bushfire Fuel Hazard Assessors And Assessment Methods In Dry Sclerophyll Forest Near Sydney, Australia, Penny J. Watson, Sandra H. Penman, Ross A. Bradstock

Faculty of Science - Papers (Archive)

Over the last decade, fire managers in Australia have embraced the concept of ‘fuel hazard’, and guides for its assessment have been produced. The reliability of these new metrics, however, remains to be determined. This study compared fuel hazard ratings generated by five assessment teams using two Australian hazard assessment methods, in two dry sclerophyll forest sites on Sydney’s urban fringe. Attributes that underpin hazard scores, such as cover and height of various fuel layers, were also assessed. We found significant differences between teams on most variables, including hazard scores. These differences were more apparent when fuel hazard assessments focussed …


Australia's Black Saturday Fires - Comparison Of Techniques For Estimating Emissions From Vegetation Fires, Clare Paton-Walsh, Louisa K. Emmons, Christine Wiedinmyer Jan 2012

Australia's Black Saturday Fires - Comparison Of Techniques For Estimating Emissions From Vegetation Fires, Clare Paton-Walsh, Louisa K. Emmons, Christine Wiedinmyer

Faculty of Science - Papers (Archive)

We present a comparison of techniques for estimating atmospheric emissions from fires using Australia's 2009 "Black Saturday" wildfires as a case study. Most of the fires started on Saturday the 7th of February 2009 (a date now known as "Black Saturday") and then spread rapidly, fanned by gale force winds, creating several firestorms and killing 173 people. The fires continued into early March, when rain and cooler conditions allowed the fires to be extinguished. In this study, we compare two new techniques (and one more established method) to estimate the total emissions of a number of atmospheric trace gases from …

The Kimberley region of northwest Australia contains one of the World's largest collections of rock art characterised by two distinct art forms; the fine featured anthropomorphic figures of the Gwion Gwion or Bradshaw paintings, and broad stroke Wandjina figures. Luminescence dating of mud wasp nests overlying Gwion Gwion paintings has confirmed an age of at least 17,000 yrs B.P. with the most recent dates for these paintings from around the mid-Holocene (5000 to 7000 yrs B.P.). Radiocarbon dating indicates that the Wandjina rock art then emerged around 3800 to 4000 yrs B.P. following a hiatus of at least 1200 yrs. …

Optically stimulated luminescence (OSL) ages from a relict shoreline on Lake Callabonna record a major pluvial episode in southern central Australia between 1050 ± 70 and 1100 ± 60 Common Era (CE), within the Medieval Climatic Anomaly (MCA). During this pluvial interval Lake Callabonna filled to 10–12 times the volume of the largest historical filling (1974) and reached maximum depths of 4–5 m, compared to the 0.5–1.0 m achieved today. Until now there has been no direct evidence for the MCA in the arid interior of Australia. A multi-proxy, analogue-based atmospheric circulation reconstruction indicates that the pluvial episode was associated …


The Influence Of Prescribed Fire On The Extent Of Wildfire In Savanna Landscapes Of Western Arnhem Land, Australia, Owen F. Price, Jeremy Russell-Smith, Felicity Watt Jan 2012

The Influence Of Prescribed Fire On The Extent Of Wildfire In Savanna Landscapes Of Western Arnhem Land, Australia, Owen F. Price, Jeremy Russell-Smith, Felicity Watt

Faculty of Science - Papers (Archive)

Fire regimes in many north Australian savanna regions are today characterised by frequent wildfires occurring in the latter part of the 7-month dry season. A fire management program instigated from 2005 over 24 000 km2 of biodiversity-rich Western Arnhem Land aims to reduce the area and severity of late dry-season fires, and associated greenhouse gas emissions, through targeted early dry-season prescribed burning. This study used fire history mapping derived mostly from Landsat imagery over the period 1990-2009 and statistical modelling to quantify the mitigation of late dry-season wildfire through prescribed burning. From 2005, there has been a reduction in mean …

"Studies of long-term vegetation changes are critical for enhancing our understanding of successional dynamics in natural ecosystems. Bycomparing forest inventory data from the 1940s against field data from 2005, we document changes in stand structure over 60 years in forests co-dominated by Callitris glaucophylla J. Thompson & L. Johnson, Allocasuarina luehmannii (R. Baker) L. Johnson and Eucalyptus crebra F.Muell., in central Pilliga, New South Wales (NSW), Australia. Sampling was stratified across two forest types and across a 1951 wildfire boundary, to assess the effects of initial stand structure and early disturbance on stand dynamics. Stems in the size range tallied …

The nature of the Australian climate at about the time of rapid megafaunal extinctions and humans arriving in Australia is poorly understood and is an important element in the contentious debate as to whether humans or climate caused the extinctions. Here we present a new paleoshoreline chronology that extends over the past 100 k.y. for Lake Mega-Frome, the coalescence of Lakes Frome, Blanche, Callabonna and Gregory, in the southern latitudes of central Australia. We show that Lake Mega-Frome was connected for the last time to adjacent Lake Eyre at 50-47 ka, forming the largest remaining interconnected system of paleolakes on …


Tectonic Implications Of Early Paleozoic Metamorphism In The Anakie Inlier, Central Queensland, Australia, R Offler, G Phillips, C L. Fergusson, T J. Green Jan 2011

Tectonic Implications Of Early Paleozoic Metamorphism In The Anakie Inlier, Central Queensland, Australia, R Offler, G Phillips, C L. Fergusson, T J. Green

Faculty of Science - Papers (Archive)

Well-defined metamorphic zones are developed in pelitic and psammitic rocks of the Late Neoproterozoic to Cambrian Anakie Metamorphic Group of the Anakie Inlier, central Queensland. They are defined by the incoming of biotite, garnet, and andalusite, with or without staurolite. Mineral assemblages indicate that low pressure-high temperature metamorphism is associated with D1, medium pressure-high temperature metamorphism with D2, and retrograde, low pressure-low temperature metamorphism with D3. A mean b cell parameter of 9.035 obtained from K-white micas in the lowest-grade rocks suggests upper intermediate pressure conditions during D2. The timing of the growth of the index minerals indicates that isotherms …


Alunite Formation Within Silica Stalactites From The Sydney Region, South-Eastern Australia, Robert A. Wray Jan 2011

Alunite Formation Within Silica Stalactites From The Sydney Region, South-Eastern Australia, Robert A. Wray

Faculty of Science - Papers (Archive)

"This paper presents X-ray diffraction and SEM evidence for the formation of alunite, and possibly small quantities of natroalunite, within opal-A stalactites formed on quartz sandstone near Sydney in south-eastern, Australia. Alunite has been reported as a speleogenetic mineral from sediments within a number of caves around the world, but this is believed to be the first report of speleothemic alunite in opaline silica speleothems. Individual alunite crystals have not been visually identified, but SEM X-ray element mapping suggests the alunite has formed amongst kaolinite clay. Sedimentary alunite and natroalunite formation is usually associated with the reaction of sulphuric acid …

Rocky Intertidal Temperature Variability Along The Southeast Coast Of Australia: Comparing Data From In Situ Loggers, Satellite-Derived Sst And Terrestrial Weather Stations, Justin Adam Lathlean, David J. Ayre Prof, Todd E. Minchinton Jan 2011

Rocky Intertidal Temperature Variability Along The Southeast Coast Of Australia: Comparing Data From In Situ Loggers, Satellite-Derived Sst And Terrestrial Weather Stations, Justin Adam Lathlean, David J. Ayre Prof, Todd E. Minchinton

Faculty of Science - Papers (Archive)

Predicting how both spatial and temporal variation in sea and air temperature influence the distribution of intertidal organisms is a pressing issue. We used data from satellites, weather stations and in situ loggers to test the hypothesis that satellite-derived sea surface temperatures (SSTs) and weather station air temperatures provide accurate estimates of ambient temperature variability on rocky intertidal shores for temporal (hourly for 1 yr) and spatial (10 m to 400 km) variation along the southeast coast of Australia. We also tested whether satellites and weather stations accurately detect the duration, frequency and number of extreme temperature events. Daily mean …

Poor Iodine Status And Knowledge Related To Iodine On The Eve Of Mandatory Iodine Fortification In Australia, Heather Yeatman, Karen E. Charlton, Fiona Houweling

Faculty of Health and Behavioural Sciences - Papers (Archive)

Background: Mandatory fortification of bread with iodised salt is proposed to address the re-emergence of iodine deficiency in Australia and New Zealand. The impacts of fortification require baseline data of iodine status among vulnerable sectors of the population. Objective: To assess the iodine status of healthy women and to investigate consumer understanding and attitudes related to the proposed mandatory iodine fortification programme. Design: Cross-sectional sample of 78 non-pregnant women aged 20-55 y was conveniently sampled in Wollongong, NSW. A single 24-hr urine sample was collected for urinary iodine concentration (UIC). A selfadministered questionnaire assessed consumer understanding, perceptions and attitudes related …


Toddler Milk Advertising In Australia: The Infant Formula Ads We Have When We Don’T Have Infant Formula Ads, Nina J. Berry, Sandra Jones, Donald Iverson Jan 2010

Toddler Milk Advertising In Australia: The Infant Formula Ads We Have When We Don’T Have Infant Formula Ads, Nina J. Berry, Sandra Jones, Donald Iverson

Faculty of Health and Behavioural Sciences - Papers (Archive)

The Marketing in Australia of Infant Formula: Manufacturers’ and Importers’ Agreement (MAIF) prevents manufacturers and importers from advertising infant formula. However, toddler milks, which share brand identities with infant formula, are advertised freely; and recent research suggests consumers fail to distinguish between advertising for infant formula and for toddler milk. This study examined whether Australian parents recalled having seen advertisements for ‘formula’. Most respondents (66.8%) reported seeing an advertisement for infant formula, with those who had only seen non-retail advertising more than twice as likely to believe that they had seen such an advertisement as those who had only seen …


When Does Alcohol Sponsorship Of Sport Become Sports Sponsorship Of Alcohol? A Case Study Of Developments In Sport In Australia, Sandra C. Jones Jan 2010

When Does Alcohol Sponsorship Of Sport Become Sports Sponsorship Of Alcohol? A Case Study Of Developments In Sport In Australia, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

Alcohol sponsorship of sport is common in Australia, with much debate about the appropriateness of linking sport with alcohol advertising and promotion. This paper provides examples of such sponsorships to appreciate the extent and nature of complex relationship between sport and alcohol sponsors. The public health and policy implications of alcohol sponsorship of sport extending to creating a sporting competition purely to promote an alcohol brand are considered.


'The Falling Sky': Symbolic And Cosmological Associations Of The Mt William Greenstone Axe Quarry, Central Victoria, Australia, Adam R. Brumm Jan 2010

'The Falling Sky': Symbolic And Cosmological Associations Of The Mt William Greenstone Axe Quarry, Central Victoria, Australia, Adam R. Brumm

Faculty of Science - Papers (Archive)

This article examines the roles of socio-symbolic practices and cosmological beliefs in the production and exchange of stone artefacts in an ethnohistorically documented context in Australia. Isabel McBryde's petrological and ethnohistorical analysis of greenstone axe distribution patterns in central Victoria provides a key example of social factors overriding technological concerns in the production and exchange of lithic artefacts. Her research shows that greenstone axes from Mt William quarry were distributed further than axes from equivalent sources. This suggests that Mt William stone axes had symbolic values that cannot be appreciated from straightforward economic perspectives - the aim of this article …


Evidence Of Solar And Tropical-Ocean Forcing Of Hydroclimate Cycles In Southeastern Australia For The Past 6500 Years, Hamish A. Mcgowan, Samuel K. Marx, Joshua Soderholm, John Denholm Jan 2010

Evidence Of Solar And Tropical-Ocean Forcing Of Hydroclimate Cycles In Southeastern Australia For The Past 6500 Years, Hamish A. Mcgowan, Samuel K. Marx, Joshua Soderholm, John Denholm

Faculty of Science - Papers (Archive)

Evidence of solar and tropical‐ocean forcing of climate cycles has been found in numerous palaeoclimate records. Numerical modelling studies show physical mechanisms by which direct and indirect solar forcing may affect climate, while there is mounting evidence of solar forcing of tropical ocean‐atmosphere teleconnections. This study has developed a 6500 year record of dust deposition, a proxy for regional hydroclimate variability for the Snowy Mountains region of Australia. Spectral analysis of the record provides evidence of statistically significant cycles in dust deposition of 35–43 years, 62–73 years, 161 years and 2200 years. These correlate with variability in solar irradiance and …

Formaldehyde And Nitrogen Dioxide In Smoke Plumes From Australia's Black Saturday Fires, Emma Young, Clare Paton-Walsh Jan 2010

Formaldehyde And Nitrogen Dioxide In Smoke Plumes From Australia's Black Saturday Fires, Emma Young, Clare Paton-Walsh

Faculty of Science - Papers (Archive)

The ‘Black Saturday’ fires were a series of devastating bushfires that burned across Victoria, Australia, during February 2009. The smoke plume from Saturday the 7th February, the worst day of the fires, separated from subsequent emissions and persisted for several weeks, providing the opportunity to track the changing composition of the smoke plume as it aged. In this study we have used satellite data from the Ozone Monitoring Instrument (OMI) and the Atmospheric InfraRed Sounder (AIRS) to characterise the emissions of formaldehyde and nitrogen dioxide from the fires. Emission ratios with respect to carbon monoxide are determined for formaldehyde (0.017 …

Port Curtis is a rapidly growing industrialised and urbanised harbour in Central Queensland, Australia. Water sampling surveys were undertaken in late 2003 and 2004, accompanied by additional sediment sampling to investigate the sources and behaviour of trace metals, and the effects of pH on metal partitioning between dissolved and particulate forms. Sampling and analyses of trace metals in waters and suspended particulates were undertaken along axial transects extending away from possible point-sources within the harbour. Additional sampling was undertaken in selected inlets and major freshwater sources to Port Curtis, including the Fitzroy River. Most dissolved metal concentrations were significantly elevated …


Train-Borne Measurements Of Tropical Methane Enhancements From Ephemeral Wetlands In Australia, Nicholas M. Deutscher, David W. T Griffith, Clare Paton-Walsh, Rittick Borah Jan 2010

Train-Borne Measurements Of Tropical Methane Enhancements From Ephemeral Wetlands In Australia, Nicholas M. Deutscher, David W. T Griffith, Clare Paton-Walsh, Rittick Borah

Faculty of Science - Papers (Archive)

We report greenhouse gas concentrations measured on a train covering a north-south transect through central Australia from north to south coast. During the monsoonal wet season we found significant enhancements in methane that correlate well with changing area of wetland inundation in Australian tropical savanna regions. We used a meteorological and air pollution model to quantify the ephemeral wetland fluxes necessary to cause the observed enhancements and estimate the constant Australian tropical wetland emissions. Annual Australian tropical ephemeral wetland fluxes are estimated at 0.4 +/- 0.2 Tg CH4, with permanent wetlands contributing a similar amount, 0.5 +/- 0.2 Tg CH4.

Mapping Same-Sex Couple Family Households In Australia, Andrew W. Gorman-Murray, Christopher R. Brennan-Horley, Kirsten Mclean, Gordon R. Waitt, Christopher R. Gibson

Faculty of Science - Papers (Archive)

The map (1:1,218,987) accompanying this report is the first to depict the distribution of same-sex couple family households across Australia. The map and the report contribute to emerging scholarship combining critical geographies of sexualities with quantitative techniques and GIS in order to advance the political claims of sexual minorities. The data were collected through the 2006 Census and obtained via consultation with the Australian Bureau of Statistics. These data included the number of same-sex couple family households for all Statistical Divisions across Australia and for Statistical Sub-Divisions within metropolitan capital cities. Geographical concentrations of same-sex couple family households were determined …
