Terrify and control: the politics of risk society

The article presents information on the idea of risk management. The origins of the contemporary constructions of risk are found in the seventeenth century, with the development of maritime insurance. In the context of maritime trading, risk came to be seen in terms of the balance between acquisitive opportunities and potential dangers and calculations of future loss of a ship or cargo. Today perceptions of risk affect our actions and strategies in areas of our life as diverse as health, parenting, crime prevention, recreation and travel. Public policy tends to be focused around risk avoidance and risk management, particularly in areas of child protection and aged care. While most of the discussions of risk have focused on risks as bads in society, risk has also been identified as a good. Risk is deemed a good when it challenges people to think differently and creatively. From a neo-liberal perspective risk opens up opportunities for unleashing of entrepreneurial capacity. In the context of the modernist commitment to the idea that people have the potential to control their own destiny, identification of threats and dangers can energize people to be adventurous. The discourse of risk has framed all the reports of the outbreaks of new strains of infection and includes instructions on how to recognize the risk assessments of its spread and instructions on how to avoid its spread.

Adolescent and parental perceptions of interparental conflict

Research indicates adolescent adjustment problems are associated with high levels of interparental conflict. This study examined parents’ and adolescents’ perceptions of interparental conflict and the relationship of these perceptions to adolescent adjustment through a survey of adolescent secondary students and their parents. Sixty-two adolescents and 62 parents participated in the study. Adolescents completed three self-report measures of psychological adjustment, a demographic questionnaire and the Consensus and Cohesion subscales of the Dyadic Adjustment Scale (DAS). Parents completed the same subscales of the DAS and a demographic questionnaire. There were no significant differences between the levels of interparental conflict perceived by adolescents and parents. However, adolescent perceptions of interparental conflict were a better predictor of adolescent psychological adjustment when compared to parental perceptions of conflict. The results of this study emphasise the importance of adolescent perceptions of interparental conflict, and provide support for both parental and adolescent reports of family functioning to be taken into account in future clinical studies.

Recent indigenous theatre in Australia:the politics of autobiography

Over the past decade Australian theatre has seen an increased profile for works written and created by Indigenous artists. This paper looks at the development of Indigenous theatre in Australia and considers how increased mainstream production opportunities have facilitated this expansion of Indigenous theatre practice. Based on the textual analysis of a number of key works, this paper looks at the development of the one-person show as the dominant genre for Indigenous theatre practices, and investigates the relationship between autobiography and the celebration of ‘otherness’. This study argues that this theatre work represents a shift away from conventional representations of Aboriginality towards a more self-determined expression of political identity.

The economics and politics of wilderness conservation in Australia

Wilderness conservation has a checkered history in Australian politics. Initially, wilderness was protected in national parks, and specific areas or legislation did not exist. In the 1960s, wilderness conservation became an important issue in Australian politics. Pressure from environmental groups and the general public created several conflicts. Several successes were scored by the joint efforts of interest groups, the public, charismatic individuals, the media, and support of governments and politicians. A number of areas were declared wilderness areas and several states now have wilderness protected through legislation. The 1990s have not been as good as the previous decades for wilderness. Large forest areas are still being cleared and bias toward consumptive use of forest by governments is emerging. Clearly, wilderness protection in Australia is intensely political. It is important that interest groups maintain pressure to protect future wilderness. Efforts to obtain national legislation for wilderness and to couch wilderness in terms of other aspects such as biodiversity and ecosystems values may prove necessary.

A politics of what: the enactment of peritoneal dialysis in indigenous Australians

This paper explores, on the one hand, the requirements of the technologies and practices that have been developed for a particular type of renal patient and health network in Australia. On the other, we examine the cultural and practical specificities entailed in the performance of these technologies and practices in the Indigenous Australian context. The praxiographic orientation of the actor-network approach – which has been called 'the politics of what' (Mol 2002) – enabled us to understand the difficulties involved in translating renal healthcare networks across cultural contexts in Australia; to understand the dynamic and contested nature of these networks; and to suggest possible strategies that make use of the tensions between these two disparate networks in ways that might ensure better healthcare for Indigenous renal patients.

Implementation of novel methods of global and nonsmooth optimization : GANSO programming library

We discuss the implementation of a number of modern methods of global and nonsmooth continuous optimization, based on the ideas of Rubinov, in a programming library GANSO. GANSO implements the derivative-free bundle method, the extended cutting angle method, dynamical system-based optimization and their various combinations and heuristics. We outline the main ideas behind each method, and report on the interfacing with Matlab and Maple packages.

Modelling the diffuse fraction of global solar radiation on a horizontal surface

For various applications it is necessary to know not only global solar radiation values, but also the diffuse and beam components. Because often only global values are available, there have been several models developed to establish correlations between the diffuse fraction and various predictors. These typically include the clearness index, but also may include the solar angle, temperature and humidity. The clearness index is the proportion of extraterrestrial radiation reaching a location, where the extraterrestrial value used in the calculation varies with latitude and time of year. These correlations have been developed using data principally from latitudes greater than 40°, often using only data from a few locations and with few exceptions have not used solar altitude as a predictor. Generally the data consist of hourly integrated values. A model has been developed using hourly data from a weather station set up at Deakin University, Geelong. Another model has also been developed for 15 minute data values in order to ascertain if the smoothing generated by using hourly data makes a significant difference to overall results. The construction of such models has been investigated, enabling an extension to the research, inclusive of other stations, to be performed systematically. A final investigation was carried out, using data from other Australian locations, to explain some of the considerable scatter by adding apparent solar time as a predictor, which proved to be significantly better than solar altitude.
