Polyfluoroalkyl chemicals in pooled blood serum from infants, children and adults in Australia

Polyfluoroalkyl chemicals (PFCs) have been used worldwide for more than 50 years in a wide variety of industrial and consumer products. Limited data exist on human exposure to PFCs in the Southern Hemisphere. Human blood serum collected in southeast Queensland, Australia, in 2006−2007 from 2420 donors was pooled according to age (cord blood, 0−0.5, 0.6−1, 1.1−1.5, 1.6−2, 2.1−2.5, 2.6−3, 3.1−3.5, 3.6−4, 4.1−6, 6.1−9, 9.1−12, 12.1−15, 16−30, 31−45, 46−60, and >60 years) and gender and was analyzed for eight PFCs. Across all pools, perfluorooctane sulfonate (PFOS) was detected at the highest mean concentration (15.2 ng/mL) followed by perfluorooctanoate (PFOA, 6.4 ng/mL), perfluorohexane sulfonate (PFHxS, 3.1 ng/mL), perfluorononanoate (PFNA, 0.8 ng/mL), 2-(N-methyl-perfluorooctance sulfonamide) acetate (Me-PFOSA-AcOH, 0.66 ng/mL), and perfluorodecanoate (PFDeA, 0.29 ng/mL). Perfluorooctane sulfonamide was detected in only 24% of the pools, and 2-(N-ethylperfluorooctane sulfonamide) acetate was detected in only one. PFOS concentrations were significantly higher in pools from adult males than from adult females (p = 0.002); no gender differences were apparent in the pools from children (<12 years old). The highest mean concentrations of PFOA, PFHxS, PFNA, PFDeA, and Me-PFOSA-AcOH were found in children <15 years, while PFOS was highest in adults >60 years. Investigation into the sources and exposure pathways in Australia, in particular for children, is necessary as well as continued biomonitoring to determine the potential effects on human concentrations as a result of changes in the PFC manufacturing practices, including the cessation of production of several PFCs.

Employment Relations in Australia, 2nd Edition

The relationship between employers and employees has been one of the most hotly debated issues in Australia in recent times. Recent legislation such as the Workplace Relations Amendment (Work Choices) Act 2005 and the subsequent Fair Work Act 2009 provides stark evidence of this. The impact of these significant developments is explored and analysed in detail in the new edition of this popular text, complete with a balanced coverage of the often contrasting viewpoints of all stakeholders - from governments, unions and employer associations, through to individual employers and employees. The text outlines different approaches to understanding the nature of the employment relationship, with a contextual background as to how this relationship has changed and developed throughout our nation's history.

An adaptable framework for the teaching and assessment of software development across year levels

Few frameworks exist for the teaching and assessment of programming subjects that are coherent and logical. Nor are they sufficiently generic and adaptable to be used outside the particular tertiary institutions in which they were developed. This paper presents the Teaching and Assessment of Software Development (TASD) frame-work. We describe its development and implementation at an Australian university and demonstrate, with examples, how it has been used, with supporting data. Extracts of criteria sheets (grading rubrics) for a variety of assessment tasks are included. The numerous advantages of this new framework are discussed with comparisons made to those reported in the published literature.

Open Access and Public Sector Information : Policy Developments in Australia and Key Jurisdictions

This book chapter considers recent developments in Australia and key jurisdictions both in relation to the formation of a national information strategy and the management of legal rights in public sector information.

Prison foodservice in Australia : systems, menus and inmate attitudes

This paper presents results from three studies in 25 custodial facilities in three Australian states, including nutrient analyses of menus and focus groups exploring inmate attitudes. Both cook-fresh and cook-chill production systems are used. Non-selective cycle menus of 4-6 weeks are common but inmates can supplement meals by purchase of additional food items (‘buy-ups’). Menus included adequate variety and met most nutritional standards, with the possible exception of fruit. The sodium content of menus is above recommended levels. Protein, fibre, vitamins A, C, thiamin, riboflavin, calcium, iron and zinc were more than adequate, and the percentage energy from fat is close to or meets national recommendations. Focus groups identified 16 themes, including meal quality, food available at ‘buy-ups’, cooking facilities, and concerns about possible food safety risks associated with inmates storing food in cells. Many complaints were about factors not under the control of the foodservice manager.

Advance Australia Fair : social democratic and conservative politicians’ discourses concerning Aboriginal and Torres Strait Islander Peoples and their health 1972–2001

This paper reports research undertaken as part of a larger project in which we examined whether and how values and beliefs communicated by Australian politicians have shaped decades of health policy and influenced health outcomes for Aboriginal and Torres Strait Islander Peoples of Australia. To first characterise those values and beliefs we analysed the public statements of the politicians responsible nationally for the health of Aboriginal and Torres Strait Islander Peoples 1972–2001, using critical discourse analysis. We found that four discourses, communicated through words, phrases, sentences and grammatical structures, dominated public statements over the study period. These four discourses focused on the competence and capacity of Aboriginal and Torres Strait Islander Peoples to “manage”; matters of control of and responsibility for the health of Aboriginal and Torres Strait Islander Peoples; Aboriginal and Torres Strait Islander Peoples as “Other”; and the nature of the “problem” concerning the health of Aboriginal and Torres Strait Islander Peoples. Analysis of the discursive elements contributing to shaping these four discourses is reported in this paper.

Consumer guarantees in Australia : putting an end to the blame game

The focus of this article is on the proposed consumer guarantees component of the Australian Consumer Law. The Productivity Commission (PC), in its review of Australia’s Consumer Policy Framework, noted that it had not ‘undertaken the detailed analysis necessary to reach a judgment on the adequacy or otherwise of the existing regulation in this area, or the merits of alternative models such as those adopted in countries such as New Zealand’. Accordingly, it recommended that: ‘The adequacy of existing legislation related to implied warranties and conditions should be examined as part of the development of the new national generic consumer law’.

A practical example of a siphon at work

In this paper, some classroom experiments are described for correcting the common misconception that the operation of a siphon depends on atmospheric pressure. One experiment makes use of a chain model of a siphon and another demonstrates that flow rate is dependent on the height difference between the inflow and outflow of a siphon and not atmospheric pressure. A real-life example of the use of a siphon to refill a lake in South Australia is described, demonstrating that the siphon is not only of academic interest but has practical applications.

Voter behaviour and constitutional change in Australia since 1967

Australian Constitutional referendums have been part of the Australian political system since federation. Up to the year 1999 (the time of the last referendum in Australia), constitutional change in Australia does not have a good history of acceptance. Since 1901, there have been 44 proposed constitutional changes with eight gaining the required acceptance according to section 128 of the Australian Constitution. In the modern era since 1967, there have been 20 proposals over seven referendum votes for a total of four changes. Over this same period, there have been 13 federal general elections which have realised change in government just five times. This research examines the electoral behaviour of Australian voters from 1967 to 1999 for each referendum. Party identification has long been a key indicator in general election voting. This research considers whether the dominant theory of voter behaviour in general elections (the Michigan Model) provides a plausible explanation for voting in Australian referendums. In order to explain electoral behaviour in each referendum, this research has utilised available data from the Australian Electoral Commission, the 1996 Australian Bureau of Statistics Census data, and the 1999 Australian Constitutional Referendum Study. This data has provided the necessary variables required to measure the impact of the Michigan Model of voter behaviour. Measurements have been conducted using bivariate and multivariate analyses. Each referendum provides an overview of the events at the time of the referendum as well as the =yes‘ and =no‘ cases at the time each referendum was initiated. Results from this research provide support for the Michigan Model of voter behaviour in Australian referendum voting. This research concludes that party identification, as a key variable of the Michigan Model, shows that voters continue to take their cues for voting from the political party they identify with in Australian referendums. However, the outcome of Australian referendums clearly shows that partisanship is only one of a number of contributory factors in constitutional referendums.

Reconciling Nicci Lane : the 'unspeakable' significance of Australia's first indigenous porn star

This article will explore X-rated representations of Aboriginality in Australian-produced pornographic videos, particularly the image of Australia's first Indigenous porn-star, Nicci Lane. It investigates how pornographic narratives involving 'Aboriginal' characters or motifs are connected to broader embodiments of Aboriginality in popular culture. Drawing a parallel with Australian television drama and mainstream films, the article highlights how contemporary sexualized images of Aboriginal people are intimately tied to a politics of reconciliation. By surveying recent literature on pornography, which describe how certain pornographic narratives engage 'unspoken' community desires, my argument will discuss Nicci Lane's career as a unique development in the history of representations of Aboriginality. Through analysis of Lane’s Arigato Baby (1991), these ‘unspoken’ desires relate to showing Indigenous people in everyday sexual contexts, as romantic partners, friends and lovers. My argument will go on to suggest that, through Nicci Lane's performance and profile, the image of Australia’s first Indigenous porn-star offers the possibility for imagining new kinds of interracial intimacy within the Australian public sphere.

Questions of English : ethics, aesthetics, rhetoric, and the formation of the subject in England, Australia and the United States

The impact and content of English as a subject on the curriculum is once more the subject of lively debate. Questions of English sets out to map the development of English as a subject and how it has come to encompass the diversity of ideas that currently characterise it. Drawing on a combination of historical analysis and recent research findings Robin Peel, Annette Patterson and Jeanne Gerlach bring together and compare important new insights on curriculum development and teaching practice from England, Australia and the United States. They also discuss the development of teacher training, highlighting the variety of ways in which teachers build their own beliefs and knowledge about English.

Revisiting Industrial Relations

In 1999 I convened Industrial Relations, the annual ADSA Conference hosted by QUT in Brisbane. This event was promoted as ‘a conference exploring the links between theatre scholarship and professional theatre practice’. As well as academics, there was to be substantial representation by ‘industry professionals’, although interest from the latter category turned out to be modest. One day of the conference was designated a special ‘Links with Industry’ day, during which the Association launched its now defunct ADSAIL (ADSA Industry Links) initiative. Keynote speaker Wesley Enoch commented on ‘the very strong resistance in “the industry” to acknowledging any role of academics’. ‘What is the practical role of having them?’ he asked the ‘them’ gathered before him. In a letter declining our invitation to speak (he later changed his mind), David Williamson remarked that he always felt ‘uneasy at such conferences’: My view of my work is that I’ve successfully filled theatres for 30 years now, something dramatists are supposed to do. I suppose there’s part of me that hopes this will be celebrated. It often is, but rarely in academic drama departments …. Perhaps in fifty years time someone in academe will realise that I wasn’t just reinforcing the attitudes of the Anglo Celtic ruling class. Several years on it seems timely to revisit Industrial Relations; to look again at the extent to which problems of intercultural communication between industry and academy are being addressed. And what are the implications of this for the ADSA History project, which seeks to investigate ADSA’s contribution to the development of theatre / performance studies in Australasia? What are the ‘external’ impacts of ADSA’s ongoing conference enterprise, and how might these be measured? Reflections from delegates on these and other questions will be warmly encouraged.

Consumer trends in digital news and information in Australia

We all know that the future of news is digital. But mainstream news providers are still grappling with how to entice more customers to their online sites. This paper provides context for a survey currently underway on user intentions towards online news and entertainment, by exploring: 1. Consumer behaviours and intentions with regards to accessing online news and information; 2. Current trends in the Australian online news and information sector; and 3. Key issues and emerging opportunities in the Australian (and global) environment. Key influences on use of online news and information are pricing and access. The paper highlights emerging technical opportunities and flags service gaps. These gaps include multiple disconnects between: 1. Changing user intentions towards online and location based news (news based on a specific locality as chosen by the user) and information; 2. The ability by consumers to act on these intentions via the availability and cost of technologies; 3. Younger users may prefer entertainment to news, or ‘infotainment’; and 4. Current online offerings of traditional news providers and opportunities. These disconnects present an opportunity for online news suppliers to appraise and resolve. Doing so may enhance their online news and information offering, attract consumers and improve loyalty. Outcomes from this paper will be used to identify knowledge gaps and contribute to the development of further analysis on Australian consumers and their behaviours and intentions towards online news and information. This will be undertaken via focus groups as part of a broader study.
