Australia's Proposed Internet Filtering System : Its Implications For Animation, Comic And Gaming (Acg) And Slash Fan Communities, Mark J. Mclelland Oct 2010

Australia's Proposed Internet Filtering System : Its Implications For Animation, Comic And Gaming (Acg) And Slash Fan Communities, Mark J. Mclelland

Faculty of Arts - Papers (Archive)

This paper investigates the implications of the Australian Government’s proposed Internet filtering system in the light of Australia’s blanket prohibition of ‘child pornography’ (including cartoons, animation, drawings, digitally manipulated photographs, and text) for Australian fan communities of ACG and slash. ACG/slash fan groups in Australia and elsewhere routinely consume, produce and disseminate material containing ‘prohibited content’ (i.e. featuring fictitious ‘under-age’ characters in violent and sexual scenarios). Moreover, a large portion of the fans producing and trading in these images are themselves ‘under age’. Focusing specifically upon the overwhelmingly female fandom surrounding Japanese ‘Boys’ Love’ (BL) manga ...


“Kissing Is A Symbol Of Democracy!” Dating, Democracy And Romance In Occupied Japan 1945-1952, Mark J. Mclelland Sep 2010

“Kissing Is A Symbol Of Democracy!” Dating, Democracy And Romance In Occupied Japan 1945-1952, Mark J. Mclelland

Faculty of Arts - Papers (Archive)

Japan’s defeat at the end of its fifteen years’ war in 1945 saw widespread changes to the family and gender system. Women were given political rights for the first time and were recognised as independent agents at work, in the home and in their romantic relationships. Whereas war-time ideology had brought about the “death of romance” in popular culture, with the relaxation of censorship at the war’s end, there was a sudden proliferation in discussion about the qualities of the “new” or “modern” couple and the popular press saw the rise of an eclectic range of “experts” offering ...

Any face seen for the first time will have a closet neighbour in memory. In order to avoid false alarms, we must be able to distinguish similar from identical faces. Work is reported investigating same/different judgments as a function difference in three dimensional shape defined in terms of standard deviation in a principal component based face space. The aim is to determine the criterion difference below which observers respond “same”. A threshold corresponding to a dprime of 1 was also calculated. Both were first measured under three conditions – same view images, different view images and animated images of the ...

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 ...

Faculty of Health and Behavioural Sciences - Papers (Archive)

Objective: Strategies that aim to facilitate reduction of the salt content of foods in Australia are hampered by sparse and outdated data on habitual salt intakes. This study assessed habitual sodium intake through urinary excretion analyses, and identified food sources of dietary sodium, as well as knowledge and practices related to salt use in healthy women. Methods: Cross-sectional, convenient sample of 76 women aged 20 to 55 years, Wollongong, NSW. Data included a 24 hour urine sample, three-day food diary and a self-administered questionnaire. Results: Mean Na excretion equated to a NaCl (salt) intake of 6.41 (SD=2.61 ...

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 ...

Industry Self-Regulation Of Food Marketing To Children: Reading The Fine Print, Lana Hebden, Lesley King, Bridget P. Kelly, Kathy Chapman, Christine Innes-Hughes

Faculty of Health and Behavioural Sciences - Papers (Archive)

Issue addressed: Despite the evidence showing the negative influences of food marketing on children’s dietary beliefs and behaviours, and risk of adiposity, regulatory action to limit unhealthy food marketing has made little progress within Australia. Our aim was to describe and critically examine the Australian Food and Grocery Council’s (AFGC) approach to self-regulate food marketing to Australian children through the Responsible Marketing to Children Initiative (Initiative). Methods: The Initiative’s core principles and the commitments of the 16 signatory companies (as at December 2009) were assessed in terms of their capacity to limit unhealthy food advertising in media ...


Does Exercise Have A Role In The Management Of Gestational Diabetes Mellitus?, Herbert Groeller, Sandra Lowe, Anthony Worsley, Arthur Jenkins Jan 2010

Does Exercise Have A Role In The Management Of Gestational Diabetes Mellitus?, Herbert Groeller, Sandra Lowe, Anthony Worsley, Arthur Jenkins

Faculty of Health and Behavioural Sciences - Papers (Archive)

Gestational diabetes mellitus (GDM) is associated with a marked increase in the long-term risk of type 2 diabetes and adverse pregnancy outcomes. Engaging in vigorous recreational physical activity prior to and during pregnancy significantly reduces the risk of developing GDM. In contrast, evidence of a therapeutic effect from participation in a structured exercise training regimen, although promising, is limited and requires further more substantial investigation. This paper briefly reviews the pathophysiology of GDM, the evidence related to physical activity participation and exercise regimen intervention on GDM, and the clinical considerations required for prescribing exercise. Key Words: gestational diabetes mellitus • exercise ...


The Importance Of Play In Organisation, Irina M. Verenikina, Helen M. Hasan Jan 2010

The Importance Of Play In Organisation, Irina M. Verenikina, Helen M. Hasan

Faculty of Health and Behavioural Sciences - Papers (Archive)

The role of play as a `social innovation' is attracting emerging research attention since it can affect the emotional climate and complex collaborative performance of the modern workplace. The psychology of play recognises the benefits of incorporating play and `playing games' at work. The increasing use of computer games throughout our society motivates the use of games and game technology for serious purposes including education, training and research. While managers are often reluctant to publicly state that play is good for work, they are willing to use the term `Serious Games'. These are games that engage users in their pursuit ...

Australian local government organisations (LGOs) are unique in terms of the variety anddiversity of services that they provide to their communities. These include traditionalfunctions like maintaining local roads, managing property information, regulating real estatedevelopment, and collecting and disposing of waste. LGO service portfolios have expandedas a result of federal and state governments devolving their traditional responsibilities to localgovernments. LGOs have also raised community expectations by delivering a vast array ofcommunity and commercial services in addition to their traditional services. For example, thecommercial services operated by Wollongong City Council (2002) include facilities such astourist parks, leisure facilities, tourist information centres, and ...

Applying An Error Taxonomy To Examine Inexperienced Spreadsheet Users' Planning And Execution Errors, Amy Y. Chan, Peter Caputi, Suzanne Hilellis, Zi Zhu, Rohan Jayasuriya

Faculty of Health and Behavioural Sciences - Papers (Archive)

This paper presents preliminary findings of an application of the Panko-Aurigemma (2010) error taxonomy to errors generated in a spreadsheet training task. Data from 11 inexperienced trainees were obtained on two spreadsheet training tasks of different complexity and scored by two judges. High levels of inter-rater reliability were obtained for a refined planning and execution error classification. Preliminary findings relating to the likely processes underlying task completion indicate that trainees make more execution than planning errors on easy tasks. Negative associations were found between the frequency of execution and planning errors and task performance when completing easy tasks. For hard ...

Easy Preparation Of Sno2@Carbon Composite Nanofibers With Improved Lithium Ion Storage Properties, Zhixin Chen, Zaiping Guo, Hua-Kun Liu, Guodong Du, Xuebin Yu, Guonan Chen, Peng Zhang, Zunxian Yang

Faculty of Health and Behavioural Sciences - Papers (Archive)

SnO2@carbon nanofibers were synthesized by a combination of electrospinning and subsequent thermal treatments in air and then in argon to demonstrate their potential use as an anode material in lithium ion battery applications. The as-prepared SnO2@carbon nanofibers consist of SnO2 anoparticles/nanocrystals encapsulated in a carbon matrix and contain many mesopores. Because of the charge pathways, both for the electrons and the lithium ions, and the buffering function provided by both the carbon encapsulating the SnO2 nanoparticles and the mesopores, which tends to alleviate the volumetric effects during the charge/discharge cycles, the nanofibers display a greatly improved ...

Australian Red Meat Consumption - Implications Of Changes Over 20 Years On Nutrient Composition, Peter Williams, Veronique Droulez Jan 2010

Australian Red Meat Consumption - Implications Of Changes Over 20 Years On Nutrient Composition, Peter Williams, Veronique Droulez

Faculty of Health and Behavioural Sciences - Papers (Archive)

Trimming fat off meat is recommended for reducing intake of saturated fat. This paper reviews trends over 20 years that have influenced the red meat supply in response to consumer and health professional demands for lean meat, drawing on published survey data, marketing information, analysis of meat content and qualitative research commission by Meat and Livestock Australia. Separable fat is the greatest determinant of the saturated fat in Australian red meat, and changes in processing and butchering practices have combined to produce red meat today with significantly lower saturated fat. Nutrient analyses in 2002 showed that the separable fat on ...

Engagement of cytokine receptors by specific ligands activate Janus kinase-signal transducer and activator of transcription (STAT) signaling pathways. The exact roles of STATs in human lymphocyte behavior remain incompletely defined. Interleukin (IL)-21 activates STAT1 and STAT3 and has emerged as a potent regulator of B cell differentiation. We have studied patients with inactivating mutations in STAT1 or STAT3 to dissect their contribution to B cell function in vivo and in response to IL-21 in vitro. STAT3 mutations dramatically reduced the number of functional, antigen (Ag)-specific memory B cells and abolished the ability of IL-21 to induce naive B ...


National Review Of Food Label Law & Policy - Australia, Heather Yeatman Jan 2010

National Review Of Food Label Law & Policy - Australia, Heather Yeatman

Faculty of Science, Medicine and Health - Papers: part A

Australia is the first country in the world to undertake a complete review of food label law and policy. This independent Review Panel is charged with examining current policies, standards and laws relevant to food labelling; the policy drivers impacting on demands for food labelling; and the policies and mechanisms that are needed to ensure that government plays its optimum role. Particular areas of nutrition focus include health claims and front of pack labelling. The genesis of the review was Australian governments' commitment to regulatory reform to create a seamless national economy, reduce the regulatory burden, and maintain or increase ...


Identifying Refugia From Climate Change, Michael B. Ashcroft Jan 2010

Identifying Refugia From Climate Change, Michael B. Ashcroft

Faculty of Science, Medicine and Health - Papers: part A

This article highlights how the loose definition of the term 'refugia' has led to discrepancies in methods used to assess the vulnerability of species to the current trend of rising global temperatures. The term 'refugia' is commonly used without distinguishing between macrorefugia and microrefugia, ex situ refugia and in situ refugia, glacial and interglacial refugia or refugia based on habitat stability and refugia based on climatic stability. It is not always clear which definition is being used, and this makes it difficult to assess the appropriateness of the methods employed. For example, it is crucial to develop accurate fine-scale climate ...

It is rarely cost-effective to survey invertebrates for use in systematic conservation planning activities. The efficiency of sampling methods needs to be improved, and this is especially important at landscape and regional scales. We investigated two methods that could be used to improve regional scale sampling efficiency using a case study of ants, beetles, flies, bugs, spiders and wasps from the semi-arid Pilbara region of Western Australia. First, Generalised Dissimilarity Models (GDMs) were used to divide the region into landscapes with relatively homogeneous communities and environmental conditions. We found that some of these landscapes were large, and a low sampling ...

Implementing Evidence-Based Practice In Taiwanese Nursing Homes Attitudes And Perceived Barriers And Facilitators, Hui Chen Chang, Cherry Russell, Mairwen Jones Jan 2010

Implementing Evidence-Based Practice In Taiwanese Nursing Homes Attitudes And Perceived Barriers And Facilitators, Hui Chen Chang, Cherry Russell, Mairwen Jones

Faculty of Science, Medicine and Health - Papers: part A

To date, there is a paucity of research investigating nurses' perceptions of evidence-based practice (EBP) in nursing homes, especially in non-Western countries. This descriptive, quantitative study investigated attitudes toward and perceived barriers and facilitators to research utilization among 89 Taiwanese RNs. The majority of nurses expressed positive attitudes toward research and EBP. The most frequently cited barriers were related to insufficient authority to change practice, difficulty understanding statistical analyses, and a perceived isolation from knowledgeable colleagues with whom to discuss the research. EBP facilitators included improved access to computers and Internet facilities in the workplace, more effective research training, and ...


Selection Of Integration Time Intervals For Quartz Osl Decay Curves, Alastair C. Cunningham, Jakob Wallinga Jan 2010

Selection Of Integration Time Intervals For Quartz Osl Decay Curves, Alastair C. Cunningham, Jakob Wallinga

Faculty of Science, Medicine and Health - Papers: part A

In quartz optically stimulated luminescence (OSL) dating protocols, an initial integral of the OSL decay curve is used in the calculation of equivalent dose, once a background integral has been subtracted. Because the OSL signal commonly contains a number of exponentially decaying components, the exact choice of time intervals used for the initial-signal and background integrals determines the composition of the net signal. Here we investigate which combination of time intervals will produce the net signal most dominated by the fast OSL component, while keeping an acceptable level of precision. Using a three-component model of OSL decay, we show that ...

Membrane Fatty Acid Composition And Longevity Of Mammals And Birds, Anthony J. Hulbert, Magdalene Trzcionka, William A. Buttemer Jan 2010

Membrane Fatty Acid Composition And Longevity Of Mammals And Birds, Anthony J. Hulbert, Magdalene Trzcionka, William A. Buttemer

Faculty of Science, Medicine and Health - Papers: part A

The fatty acid composition of membrane lipids varies systematically among species in a manner that is consistent with their metabolic rate and longevity. Because the susceptibility of fatty acids to peroxidation relates directly to their extent of unsaturation, it is possible to calculate a peroxidation index (PI) for membranes through characterization of their specific fatty acid composition. Long-living mammals and birds have membrane lipids with a lower PI than shorter-living species. Bird and mammal species with the same maximum life span also have membrane lipids with essentially the same PI. Exceptionally long-living mammals and birds usually have membrane lipids high ...

Direct measurements of OH and HO2 over a tropical rainforest were made for the first time during the GABRIEL campaign in October 2005, deploying the custom-built HORUS instrument (HydrOxyl Radical measurement Unit based on fluorescence Spectroscopy), adapted to fly in a Learjet wingpod. Biogenic hydrocarbon emissions were expected to strongly reduce the OH and HO2 mixing ratios as the air is transported from the ocean over the forest. However, surprisingly high mixing ratios of both OH and HO2 were encountered in the boundary layer over the rainforest. The HORUS instrumentation and calibration methods are described in detail and the measurement ...
