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.

Portrayal of depression and other mental illnesses in Australian nonfiction media

This study describes Australian media portrayal of mental illnesses, focusing on depression. A random sample of 1,123 items was selected for analysis from a pool of 13,389 nonfictional media items about mental illness collected between March 2000 and February 2001. Depression was portrayed more frequently than other mental illnesses. Items about depression, eating disorders, and substance use disorders most commonly described policies or programs, whereas items about schizophrenia most frequently portrayed individuals or symptoms and treatment. A minority of items about depression presented information about symptoms, causes, treatment, or prognosis. Although such information was generally accurate, a proportion of items conveyed misleading messages. There is therefore scope for increasing the level of accurate information provided about depression in the Australian media. (c) 2005 Wiley Periodicals, Inc.

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).

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.
