The right thing

For a few years in the mid 2000s, the ABC screened barely any new Australian drama. This record-breaking slump, which reached an all-time low of just three hours of programs in the year ending June 2005, spurred an industry-led campaign and a degree of public controversy that convinced the federal government to increase the corporation’s funding. An extra $70 million was provided for drama, with the majority earmarked for 2011–12. The new twenty-two-part courtroom drama series Crownies, made for the ABC by the independent production house Screentime, is the principal product.

Eating for health and the environment: Australian regulatory responses for dietary change

The Australian food system significantly contributes to a range of key environmental issues including harmful greenhouse gas emissions, air pollution, soil desertification, biodiversity loss and water scarcity. At the same time, the Australian s food system is a key cause of public health nutrition issues that stem from the co-existence of over- and under-consumption of dietary energy and nutrients. Within these challenges lie synergies and opportunities because a diet that has a lower environmental impact generally aligns with good nutrition. Australian State and Federal initiatives to influence food consumption patterns focus on individual body weight and ‘soft law’ interventions. These regulatory approaches, by focusing on select symptoms of food system failures, are fragmented, reductionist and inefficient. In order to illustrate this point, this paper will explore Australian regulatory responses to diet-related illnesses. The analysis will support the argument that only when regulatory responses to diets become embedded within reform of the current food system will substantial improvements to human and planetary health be achieved.

Predicting final disposition after stroke using the Orpington Prognostic Score

Background: Prediction of outcome after stroke is important for triage decisions, prognostic estimates for family and for appropriate resource utilization. Prognostication must be timely and simply applied. Several scales have shown good prognostic value. In Calgary, the Orpington Prognostic Score (OPS) has been used to predict outcome as an aid to rehabilitation triage. However, the OPS has not been assessed at one week for predictive capability. Methods: Among patients admitted to a sub-acute stroke unit, OPS from the first week were examined to determine if any correlation existed between final disposition after rehabilitation and first week score. The predictive validity of the OPS at one week was compared to National Institute of Health Stroke Scale (NIHSS) score at 24 hours using logistic regression and receiver operator characteristics analysis. The primary outcome was final disposition after discharge from the stroke unit if the patient went directly home, or died, or from the inpatient rehabilitation unit. Results: The first week OPS was highly predictive of final disposition. However, no major advantage in using the first week OPS was observed when compared to 24h NIHSS score. Both scales were equally predictive of final disposition of stroke patients, post rehabilitation. Conclusion: The first week OPS can be used to predict final outcome. The NIHSS at 24h provides the same prognostic information.

Robbery under arms: Copyright law and the Australia-United States free trade agreement

TThis article considers the radical, sweeping changes to Australian copyright law wrought by the Australia–United States Free Trade Agreement 2004 (AUSFTA). It contends that the agreement will result in a “piracy of the public domain”. Under this new regime, copyright owners will be able to obtain greater monopoly profits at the expense of Australian consumers, libraries and research institutions, as well as intermediaries, such as Internet service providers. Part One observes that the copyright term extension in Australia to life of the author plus 70 years for works will have a negative economic and cultural impact — with Australia’s net royalty payments estimated to be up to $88 million higher per year. Part Two argues that the adoption of stronger protection of technological protection measures modelled upon the Digital Millennium Copyright Act 1998 (U.S.) will override domestic policy–making processes, such as the Phillips Fox Digital Agenda Review, and judicial pronouncements such as the Stevens v Sony litigation. Part Three questions whether the new safe harbours protection for Internet service providers will adversely affect the sale of Telstra. This article concludes that there is a need for judicial restraint in interpreting the AUSFTA. There is an urgent call for the Federal Government to pass ameliorating reforms — such as an open–ended defence of fair use and a mechanism for orphan works. There is a need for caution in negotiating future bilateral trade agreements — lest the multinational system for the protection of copyright law be undermined.

Albert Namatjira: copyright estates and traditional knowledge

Albert Namatjira was Australia's first Indigenous professional artist. He adapted Western-style painting to express his cultural knowledge of the Arrernte country, for which he was a traditional custodian. In his lifetime, Albert Namatjira achieved great acclaim for his exceptional ability as an artist. However, after his untimely death, he was ignored by the mainstream Australian art world, because of the aesthetic prejudices and social policies of the time. A recent exhibition entitled Seeing the Centre: The art of Albert Namatjira (1902-1959) curated by Alison French has sought to redress this neglect, and provide a retrospective of his work. The exhibition has brought to light that the copyright in the artistic works of Albert Namatjira has not been passed onto his family descendants. In June 1957, Namatjira entered into a copyright agreement with John Brackenreg, the owner of a publishing company by the name of Legend Press, and the associated Artarmon Galleries in Sydney. It was agreed that Legend Press would pay royalties to Namatjira for the sole right to reproduce all of his paintings. Following Namatjira's death in 1959, the administration of his estate passed to the Public Trustee for the Northern Territory Government. The Public Trustee of the Northern Territory Government authorised the sale of Namatjira's copyright to Legend Press in 1983, thereby ending the ability of the descendents of Namatjira to benefit from on-going income from the reproduction of his works. Senator Aden Ridgeway of the Democrats has called on the Federal Government to enter into discussions with the Northern Territory Government to buy back the copyright in Albert Namatjira's works. He argued that exclusive control of the use and reproduction of his works should be restored to his descendants, as well as the receipt of all financial benefits that result from the use and reproduction of his works under copyright protection. The Senator said: 'By doing this, we will all be rewarded, because finally, belatedly, we will be showing Albert Namatjira the reverence that he has always deserved. We will be protecting his legacy for future generations'.

Identifying vulnerable carotid plaques in vivo using high resolution magnetic resonance imaging-based finite element analysis

Object. Individuals with carotid atherosclerosis develop symptoms following rupture of vulnerable plaques. Biomechanical stresses within this plaque may increase vulnerability to rupture. In this report the authors describe the use of in vivo carotid plaque imaging and computational mechanics to document the magnitude and distribution of intrinsic plaque stresses. Methods. Ten (five symptomatic and five asymptomatic) individuals underwent plaque characterization magnetic resonance (MR) imaging. Plaque geometry and composition were determined by multisequence review. Intrinsic plaque stress profiles were generated from 3D meshes by using finite element computational analysis. Differences in principal (shear) stress between normal and diseased sections of the carotid artery and between symptomatic and asymptomatic plaques were noted. Results. There was a significant difference in peak principal stress between diseased and nondiseased segments of the artery (mean difference 537.65 kPa, p < 0.05). Symptomatic plaques had higher mean stresses than asymptomatic plaques (627.6 kPa compared with 370.2 kPa, p = 0.05), which were independent of luminal stenosis and plaque composition. Conclusions. Significant differences in plaque stress exist between plaques from symptomatic individuals and those from asymptomatic individuals. The MR imaging-based computational analysis may therefore be a useful aid to identification of vulnerable plaques in vivo.

Non-medical prescribing in Australia

The announcement in the 2009 federal budget to allow nurse practitioners and midwives access to the Pharmaceutical Benefits Scheme (PBS) and the Medicare Benefits Scheme,1and the subsequent announcement of a November 2010 start date,2has brought non-medical prescribing into the public arena. Non-medical prescribing is not a new concept in Australia as nurse practitioners, podiatrists and optometrists have been authorised to prescribe under various state legislations for some time. However, state legislation is not uniform in relation to authorisation or formulary. Midwives are currently seeking prescribing rights,3and other groups such as physiotherapists and pharmacists are likely to seek them in the future.

Burning questions: Exploring the impact of a natural disaster on community pharmacies

Background The past decade has seen a rapid change in the climate system with an increased risk of extreme weather events. On and following the 3rd of January 2013, Tasmania experienced three catastrophic bushfires, which led to the evacuation of several communities, the loss of many properties, and a financial cost of approximately AUD$80 million. Objective To explore the impacts of the 2012/2013 Tasmanian bushfires on community pharmacies. Method Qualitative research methods were undertaken, employing semi-structured telephone interviews with a purposive sample of seven Tasmanian pharmacists. The interviews were recorded and transcribed, and two different methods were used to analyse the text. The first method utilised Leximancer® text analytics software to provide a birds-eye view of the conceptual structure of the text. The second method involved manual, open and axial coding, conducted independently by the two researchers for inter-rater reliability, to identify key themes in the discourse. Results Two main themes were identified - ‘people’ and ‘supply’ - from which six key concepts were derived. The six concepts were ‘patients’, ‘pharmacists’, ‘local doctor’, ‘pharmacy operations’, ‘disaster management planning’, and ‘emergency supply regulation’. Conclusion This study identified challenges faced by community pharmacists during Tasmanian bushfires. Interviewees highlighted the need for both the Tasmanian State Government and the Australian Federal Government to recognise the important primary care role that community pharmacists play during natural disasters, and therefore involve pharmacists in disaster management planning. They called for greater support and guidance for community pharmacists from regulatory and other government bodies during these events. Their comments highlighted the need for a review of Tasmania’s 3-day emergency supply regulation that allows pharmacists to provide a three-day supply of a patient’s medication without a doctor’s prescription in an emergency situation.

Quick abnormal-bid-detection method for construction contract auctions

Non-competitive bids have recently become a major concern in both Public and Private sector construction contract auctions. Consequently, several models have been developed to help identify bidders potentially involved in collusive practices. However, most of these models require complex calculations and extensive information that is difficult to obtain. The aim of this paper is to utilize recent developments for detecting abnormal bids in capped auctions (auctions with an upper bid limit set by the auctioner) and extend them to the more conventional uncapped auctions (where no such limits are set). To accomplish this, a new method is developed for estimating the values of bid distribution supports by using the solution to what has become known as the German tank problem. The model is then demonstrated and tested on a sample of real construction bid data and shown to detect cover bids with high accuracy. This work contributes to an improved understanding of abnormal bid behavior as an aid to detecting and monitoring potential collusive bid practices.

Stable expression of silencing-suppressor protein enhances the performance and longevity of an engineered metabolic pathway

Transgenic engineering of plants is important in both basic and applied research. However, the expression of a transgene can dwindle over time as the plant's small (s)RNA-guided silencing pathways shut it down. The silencing pathways have evolved as antiviral defence mechanisms, and viruses have co-evolved viral silencing-suppressor proteins (VSPs) to block them. Therefore, VSPs have been routinely used alongside desired transgene constructs to enhance their expression in transient assays. However, constitutive, stable expression of a VSP in a plant usually causes pronounced developmental abnormalities, as their actions interfere with endogenous microRNA-regulated processes, and has largely precluded the use of VSPs as an aid to stable transgene expression. In an attempt to avoid the deleterious effects but obtain the enhancing effect, a number of different VSPs were expressed exclusively in the seeds of Arabidopsis thaliana alongside a three-step transgenic pathway for the synthesis of arachidonic acid (AA), an ω-6 long chain polyunsaturated fatty acid. Results from independent transgenic events, maintained for four generations, showed that the VSP-AA-transformed plants were developmentally normal, apart from minor phenotypes at the cotyledon stage, and could produce 40% more AA than plants transformed with the AA transgene cassette alone. Intriguingly, a geminivirus VSP, V2, was constitutively expressed without causing developmental defects, as it acts on the siRNA amplification step that is not part of the miRNA pathway, and gave strong transgene enhancement. These results demonstrate that VSP expression can be used to protect and enhance stable transgene performance and has significant biotechnological application.

Valence and spatial explanations for voting in the 2013 Australian election

This paper examines the 2013 Australian federal election to test two competing models of vote choice: spatial politics and valence issues. Using data from the 2013 Australian Election Study, the analysis finds that spatial politics (measured by party identification and self-placement on the left-right spectrum) and valence issues both have significant effects on vote choice. However, spatial measures are more important than valence issues in explaining vote choice, in contrast with recent studies from Britain, Canada and the United States. Explanations for these differences are speculative, but may relate to Australia’s stable party and electoral system, including compulsory voting and the frequency of elections. The consequently high information burden faced by Australian voters may lead to a greater reliance on spatial heuristics than is found elsewhere.
