A Complementary Economy? National Markets and International Product in Early Australian Theatre Managements

The international circulation of commercial theatre in the early twentieth century was driven not only from the centres of Great Britain and the USA, but by the specific enterprise and habitus of managers in ‘complementary’ production sites such as Australia, South Africa, and New Zealand. The activity of this period suggests a de-centred competitive trade in theatrical commodities – whether performers, scripts, or productions – wherein the perceived entertainment preferences and geographies of non-metropolitan centres were formative of international enterprise. The major producers were linked in complex bonds of partnerships, family, or common experience which crossed the globe. The fractures and commonalities displayed in the partnerships of James Cassius Williamson and George Musgrove, which came to dominate and shape the fortunes of the Australian industry for much of the century, indicate the contradictory commercial and artistic pressures bearing upon entrepreneurs seeking to provide high-quality entertainment and form advantageous combinations in competition with other local and international managements. Clarke, Meynell and Gunn mounted just such spirited competition from 1906 to 1911, and their story demonstrates both the opportunities and the centralizing logic bearing upon local managements shopping and dealing in a global market. The author, Veronica Kelly, works at the University of Queensland. She is presently undertaking a study of commercial stars and managements in late nineteenth- and early twentieth-century Australia, with a focus on the star performer as model of history, gender, and nation.

Factors underlying support or opposition to biotechnology among Australian food consumers and implications for retailer-led food regulation

Despite current findings that consumers, on average, have negative attitudes to biotechnologies such as cloning and genetic engineering, considerable variability can be found in the direction and strength of these attitudes. This paper presents a path analysis of attitudinal, motivational, demographic and behavioural variables that influence consumer dispositions towards biotechnology. Among these variables, those found to be most important were: consumers' level of motivation to find natural foods; the extent to which they were motivated by convenience; whether they did the shopping for their household on a regular basis; and their sex. In terms of direct effects on dispositions to biotechnology, motivation to find natural foods had a very strong negative effect while convenience had a very strong positive effect. Sex had a moderate direct effect with women less likely to be positively disposed towards biotechnology than men. In an apparent contradiction, taking responsibility for household shopping had an equally strong positive effect on both naturalness and convenience. However, sex also played a crucial role here with a very strong effect on motivation to find natural foods (women more motivated), a minor effect on convenience (women less motivated) and a strong effect on responsibility for household shopping (women more likely to shop). The policy implications of these findings are important, given the apparent oppositional trends of some sections of the food industry to endorse biotechnology, and of the supermarkets to deliver `clean and green' non-GM foods to consumers.

Comparison of the R-70 self-heating rate of New Zealand and Australian coals to Suggate rank parameter

Samples from New Zealand and Australia have been tested in an adiabatic oven to assess the effect of rank on the R-70 selfheating rate of coal. A non-linear relationship can be defined for coals from both countries using the revised Suggate rank (S-r) parameter. Subbituminous coals have the highest R-70 self-heating rate values, which are 20 times that of high volatile A bituminous coals on a dry mineral matter free basis (similar to 1 cf. 20 degrees C h(-1)). However, the moderating effects of moisture and mineral matter can reduce this difference to only 2-3 times for coal in-situ. (c) 2005 Elsevier B.V All rights reserved.

Ethical perspectives of the Australian live export trade

Objective To examine the ethical perspectives of the Australian live export trade. Design and method The perspectives of farmers and other industry personnel, overseas consumers, the Australian public, veterinarians and the assumed interests of transported animals are compared in relation to the ethical consequences. Animal welfare, societal, personal and professional ethics are identified and the ratification of different perspectives considered. Results and conclusions There are positive and negative aspects of the trade for each stakeholder group, and the overall position adopted by any individual reflects their perspective of the balance of these components. The debate as to whether Australia should continue with the trade will be best served by consideration of the interests of all parties in the trade, including the consumers and animals, which are among the most affected by the trade. There is a need for further research to address the major welfare problems for the animals, an openness to inspection on the part of the trade and balance in media reporting.

Stale flavour volatiles in Australian commercial UHT milk during storage

Methyl ketones, aldehydes and free saturated fatty acids were measured in the headspace of samples of two indirectly processed and two directly processed Australian commercial UHT milks during room temperature storage for 16 weeks. The analytes were isolated using headspace solid phase microextraction and analysed by gas chromatography coupled with flame ionisation detection. All methyl ketones and aldehydes increased during storage, With free saturated fatty acids exhibiting little change. On average, the total methyl ketone and aldehyde concentrations in the indirectly processed UHT milks were higher than those in the directly processed samples. A strong correlation was found between the concentration of methyl ketones and various heat indices (furosine, lactulose and undenatured whey proteins) in the milk samples.

A simulation analysis of the market effect of the Australian Broadcasting Corporation

In this paper we utilise a stochastic address model of broadcast oligopoly markets to analyse the Australian broadcast television market. In particular, we examine the effect of the presence of a single government market participant in this market. An examination of the dynamics of the simulations demonstrates that the presence of a government market participant can simultaneously generate positive outcomes for viewers as well as for other market suppliers. Further examination of simulation dynamics indicates that privatisation of the government market participant results in reduced viewer choice and diversity. We also demonstrate that additional private market participants would not result in significant benefits to viewers.

Think global, act global: Corporate content streaming and Australian media policy

Australia ’s media policy agenda has recently been dominated by debate over two key issues: media ownership reform, and the local content provisions of the Australia–United States Free Trade Agreement. Challenging the tendency to analyse these issues separately, the article considers them as interlinked indicators of fundamental shifts occurring in the digital media environment. Converged media corporations increasingly seek to achieve economies of scale through ‘content streaming’: multi-purposing proprietary content across numerous digitally enabled platforms. This has resulted in rivalries for control of delivery technologies (as witnessed in media ownership debates) as well as over market access for corporate content (in the case of local content debates). The article contextualises Australia’s contemporary media policy flashpoints within international developments and longer-term industry strategising. It further questions the power of media policy as it is currently conceived to deal adequately with the challenges raised by a converging digital media marketplace.

Magnetic susceptibility measurement applied to the minerals industry

The efficiency of numerous mineral processing operations can be determined by measuring the magnetic properties of the process streams. This measurement, if done at all, is currently performed by laboratory testing of spot samples. This is an inherently slow process and, where feed grades are variable, optimum performance is generally not achieved. This paper describes the rapid measurement of the magnetic properties of minerals. AC measurement techniques, including the analysis of the phase component of the magnetic vector; frequency dependent magnetic susceptibility and the effect of applied magnetic field strength will be discussed. Industrial applications in mineral sands, copper smelting, ferrosilicon testing and drill core scanning will be reported. (C) 2006 Elsevier Ltd. All rights reserved.

Crisis management and risk communication: Why the food industry must get it right

There is public unease about food-related issues including food additives, food poisoning bacteria and GM ingredients. The public wants evidence of no risks, but all regulators can ever offer is no evidence of risk or evidence of a very small risk. The situation is complex because experts and non-experts can perceive the same risk in vastly different ways. The way in which the food industry manages crises and communicates risks will determine the public acceptance and success of new technologies such as GM foods and nanomaterials. There is a need for the food industry (including regulators and scientific experts) to sharpen up their risk communication skills to ensure that technical innovations are accepted by consumers, and crises such as food recalls do not undermine the public's confidence in the food industry. The AIFST has a key role to play in driving the risk communication process and allaying public unease about food-related issues.

Specific heat capacity of Australian honeys from 35 to 165C as a function of composition using differential scanning calorimetry

Modulated temperature differential scanning calorimetry was used to investigate the specific heat capacity (C-p) of 10 Australian honeys within the processing and handling temperatures. The values obtained were found to be different from the literature values at certain temperatures, and are not predictable by the additive model. The C-p of each honey exhibited a cubic relationship (P < 0.001) with the temperature (T, C). In addition, the moisture (M, %), fructose (F, %) and glucose (G, %) contents of the honeys influenced their C-p. The following equation (r(2) = 0.92) was proposed for estimating C-p of honey, and is recommended for use in the honey industry and in research: C = 996.7 + 1.4 x 10(-3)T + 5.6 x 10(-5)T(2) - 2.4 x 10(-7)T(3) - 56.5M - 25.8F - 31.0G + 1.5(M * F) + 1.8(M * G) + 0.8(F * G) - 4.6 x 10(-2) (M * F * G).

Tyre-force estimation by Kalman inverse filtering: applications to off-highway mining trucks

Kalman inverse filtering is used to develop a methodology for real-time estimation of forces acting at the interface between tyre and road on large off-highway mining trucks. The system model formulated is capable of estimating the three components of tyre-force at each wheel of the truck using a practical set of measurements and inputs. Good tracking is obtained by the estimated tyre-forces when compared with those simulated by an ADAMS virtual-truck model. A sensitivity analysis determines the susceptibility of the tyre-force estimates to uncertainties in the truck's parameters.

Wonder Down Under: Australian sci-fi 1948-52

Moral guardians, industry protectionists and concerned citizens (each with their own political agendas) had, or many years, lobbied various Ministers of Customs to regulate the offensive material which flooded the local market-the war effectively opened a protectionist climate in which the local publishing industry nourished (Johnson-Woods Pulp Friction). Though westerns dominated at first, science fiction (i.e., futuristic stories, alternative histories, space exploration, time-travel past and future ) soon followed. Within the decaying and yellowed pages, contemporary readers have a glimpse into the culture of the 1950s and, amusing though some of the predictions are, the cultural and social critic gains some understanding of the anxieties and desires of post-World War II Australia.

Responses of four Australian tree species to toxic concentrations of copper in solution culture

In Australia, metal-contaminated sites, including those with elevated levels of copper (Cu), are frequently revegetated with endemic plants. Little is known about the responses of Australian plants to excess Cu. Acacia holosericea, Eucalyptus crebra, Eucalyptus camaldulensis, and Melaleuca leucadendra were grown in solution culture with six Cu treatments (0.1 to 40 mu M). While A. holosericea was the most tolerant to excess Cu, all of the species tested were sensitive to excess Cu when compared with exotic tree and agricultural species. The critical external concentrations for toxicity were < 0.7 mu M for all species tested. There was little differentiation between shoot-tissue Cu concentrations in normal versus treated plants, thus, the derivation of critical shoot concentrations was possible only for the most tolerant species, A. holosericea. Critical root Cu concentrations were approximately 210 mu g g(-1) (A. holosericea), 150 mu g g(-1) (E. crebra), 25 mu g g(-1) (E. camaldulensis), and 165 mu g g(-1) (M. leucadendra). These results provide the first comprehensive combination of growth responses, critical concentrations, and toxicity symptoms for three important Australian genera for use in the management of Cu-contaminated sites.
