Evaluation of heat stress indices using physiological comparisons in an alumina refinery in a sub-tropical climate

The production of alumina involves the use of a process known as the Bayer process. This method involves the digestion of raw bauxite in sodium hydroxide at temperatures around 250°C. The resultant pregnant liquor then goes through a number of filtering and precipitation processes to obtain the aluminium oxide crystals which are then calcined to obtain the final product. The plant is situated in a sub tropical climate in Northern Australia and this combined with the hot nature of the process results in a potential for heat related illnesses to develop. When assessing a work environment for heat stress a heat stress index is often employed as a guideline and to date the Wet Bulb Globe Temperature (WBGT) has been the recommended index. There have been concerns over the past that the WBGT is not suited to the Northern Australian climate and in fact studies in other countries have suggested this is the case. This study was undertaken in the alumina plant situated in Gladstone Queensland to assess if WBGT was in fact the most suitable index for use or if another was more applicable. To this end three indices, Wet Bulb Globe Temperature (WBGT), Heat Stress Index (HSI) and Required Sweat Rate (SWreq) were compared and assessed using physiological monitoring of heart rate and surrogate core temperature. A number of different jobs and locations around the plant were investigated utilising personal and environmental monitoring equipment. These results were then collated and analysed using a computer program written as part of the study for the manipulation of the environmental data . Physiological assessment was carried out using methods approved by international bodies such as National Institute for Occupational Safety & Health (NIOSH) and International Standards Organisation (ISO) and incorporated the use of a ‘Physiological Factor’ developed to enable the comparison of predicted allowable exposure times and strain on the individual. Results indicated that of the three indices tested, Required Sweat Rate was found to be the most suitable for the climate and in the environment of interest. The WBGT system was suitable in areas in the moderate temperature range (ie 28 to 32°C) but had some deficiencies above this temperature or where the relative humidity exceeded approximately 80%. It was however suitable as a first estimate or first line indicator. HSI over-estimated the physiological strain in situations of high temperatures, low air flows and exaggerated the benefit of artificial air flows on the worker in certain environments ie. fans.

Profiling the sport consumption attitudes and behaviours of fantasy football players

Most sporting codes encourage participation in Fantasy Sport (FS), despite few making direct revenue from it. There is a lack of empirical evidence whether this is good practice, for although FS can increase involvement and education, it may also compete with other forms of sport consumption for consumers limited resources. This study begins to address whether FS competes with or  complements sport consumption by comparing FS players with nonplayers. Data was collected from surveys (n=182) of AFL fans, with findings indicating FS players had higher tested measures of attitudes (e.g., team identification, commitment) and behaviours (e.g., game attendance, television viewing) related  to the sport. What remains to be determined is causality, and suggestions on how to examine this are given.

The future of football is female : a case of fan-tastic imaginings?

Consistent with FIFA president Sepp Blatter’s proclamation that the future of football is female, the Australian Football League (AFL) has instituted a range of initiatives in an attempt to present a ‘female friendly’ face and garner women’s support for the national game. Given the large number of women who follow the AFL, especially in comparison to other football codes nationally, it’s worth considering the motivations behind the AFL’s tactics. To what extent does what the AFL think women want correlate with women supporters’ experiences and realities of being a football fan? This paper presents findings from semi-structured and focus group interviews with female AFL fans to gauge their perceptions of being an Australian rules football supporter and its impact on their lived experiences and sense of self. The responses of women supporters are critically assessed in order to contemplate how women negotiate gender identity through their support of a male dominated sport. As well as offering insights into the role gender plays in leisure pursuits such as sport spectatorship, this paper considers how femininity and masculinity might be contested and/or remade through the practice of following football in the Australian context. By demonstrating the range and diversity of women’s experiences, this research has the capacity to generate alternative imaginings of fanship and sporting community beyond gender stereotypes.

The factors influencing churn rates among season ticket holders : an empirical analysis

Season ticket holders (STHs) are vital to professional sport club revenue and are purported to be the most loyal and involved of fans. Nonrenewal (churn) rates among STHs, however, often exceed 20%. Low member satisfaction, poor onfield performance and low game attendance have all been posited as explanations of high churn rates, but rarely empirically examined. The research reported here employed a unique study of over 4,500 STHs, incorporating both survey research and measures of actual behavior, to determine which variables best explain and predict churn within two professional sport teams. A variety of analytical techniques all suggest that the key variables predicting churn are length of relationship and the number of games attended. New, low attending STHs are over five times more likely to churn than long-term, frequent attendees. Typical management practice is to run reward schemes designed to increase attendance and encourage renewal. The results of this study suggest that fundamental differences in the way new, low attending members evaluate the season ticket product may render those schemes ineffective. Shifting the focus of these STHs toward the intangibles of the product, such as stronger feelings of involvement, a sense of community and increased patron worth, could be more effective at reducing churn.

Pieces of me : celebrity confessional carnality

In this article I explore the carnal nature of the celebrity confession. I argue that when the celebrity confesses they do so in, through, and with their revelatory bodies. The carnal celebrity confessional is very clearly a self-reflexive performance, often stage-managed and manipulative, and therefore designed to raise, redeem, or resurrect a profile, or for damage limitation. But it can also be, depending on the performative context, an “authentic” doorway into the crisis of the celebrity's living phenomenological self. The carnal confessional, then, can be an explicit, compliant or forced will to reveal all through the celebrity body that had guaranteed them fame in the first place, but which now fails them in some way. Or, it can be an unconscious, unthought, pre-semiotic sense-based revelation - a sensational leak - about some “truth” or damage that has/is being done to them as icons of desire. This phenomenological leak has the ability to make intimate the relationship between the celebrity confessor and the fans who receive it. I will conclude that celebrity confessional carnality can be read as a productive form of bio-power.

In this article the carnality of the celebrity confession will be read in terms of its relationship to Christianity and corporeal religiosity; to therapy discourse; to docility and active agency; and to affective intimacy. Britney Spears will be my central case study. I begin the article, however, with an overview of the embodied nature of the confessional, and its centrality to mediated life and individual self-worth, using Catholicism and the television therapy talkshow as my conjoining illustrative entry point.

Maritime archaeology and trans-oceanic trade : a case study of the Oranjemund Shipwreck Cargo, Namibia

Routine sand dredging for alluvial diamonds at Oranjemund on the southern coast of Namibia exposed remnants of a long forgotten Portuguese merchant ship believed to have wrecked in the 1530s. The rescue excavations yielded over 40 tons of cargo consisting of thousands of gold and silver coins, tons of copper and lead ingots, and large quantities of ivory together with food refuse, part of personal possessions and the superstructure of the ship. This paper discusses the cargo from the shipwreck. The varying provenances show that overland inter-and intra-regional networks fed into the maritime trade between Europe and the Indian sub-continent. As such, the wreck is a lens through which we can view what was happening on the seas as well as on land. Finally we consider wider issues raised by this discovery relating to the protection and management of such material wherever it may be found in future.

Finding footy : female fan socialization and Australian rules football

The question of how, irrespective of gender, a person becomes a sports fan has been absent in sociological studies of sports supporters. Distinct from other studies of sport spectatorship that focus on the practices of already existing (and overwhelmingly male) fans, our research is the first to consider how women become supporters, and in doing so, it begins to redress the significant under-representation of women in sports fan research. From interviews with female supporters of the Australian Football League (AFL), this article identifies and critically assesses the modes by which women come to support sport. We propose four categories to explain the different ways women accomplish fandom, focusing on the importance of strong social ties and doxic actions in this process. The events, experiences and social relations that inform women's first encounters with AFL offers a template for the wider consideration of women as social agents in the sporting landscape.

Football's culture of intoxication : implications for health promotion

Objectives: The objective of this is article is to examine some of the strategies and interventions designed to encourage responsible alcohol consumption within Australian Rules football clubs.
Design: Qualitative research was undertaken with fans of four fans of football teams who compete in the South Australian National Football League (SANFL). In total, 93 interviews were conducted with male (80) and female (13) fans across these clubs. Interview data were thematically analysed with the assistance of the NVIVO software package. To elicit additional insight about the social meanings of drinking, researchers visited football games and a range of social functions.
Results: Analysis of the qualitative data suggests that formal interventions implemented by football clubs often prove ineffectual in encouraging responsible alcohol consumption, with more effective strategies aimed at dissuading heavy drinking being operationalized at an informal level by drinkers themselves through a number of ‘everyday’ or ‘lay’ strategies. Such strategies correspond to the broad analytical categories of ‘keeping safe’, ‘minimising damage’ and ‘taking charge’.
Conclusion: This focus on the role of lay strategies in informing health behaviours makes an important contribution to how we understand health promotion initiatives in relation to harmful drinking in sport and other contexts.

Everyday risks and professional dilemmas : fieldwork with alcohol-based (sporting) subcultures

This article discusses some of the everyday risks and professional dilemmas encountered when conducting participant-observation based research into the use and meaning of alcohol among fans of Australian Rules football. The key risks and dilemmas were those that emerged from female researchers entering into a predominantly male football subculture in which alcohol is routinely (and often excessively) consumed, the negotiation of key gatekeepers, the potential dangers of conducting research with participants who are inebriated and the duty of care to research participants. The article draws on an eighteen-month period of ethnographic fieldwork to highlight the risks and dilemmas negotiated and re-negotiated throughout the research process. The article argues that a failure to attend to these and other risks and dilemmas can threaten the viability of research among drinking-based communities and subcultures.

Thermal and ventilation performance of a multifunctional sports hall within an aquatic centre

There has been an increasing demand for sports facilities in urban areas recently. As a result of this, more attention is drawn towards not only the energy performance of these building typologies, but also creating a healthy indoor environment for the users. This Study investigates the thermal and ventilation performance of a sports hall within an aquatic centre using computational fluid dynamics (CFD) simulations. IES Virtual Environment software was used to perform the simulations. A number of scenarios were tested by changing the position of extract fans as well as by incorporating natural ventilation strategies. A high level of discomfort was observed in the space. Better comfort condition was achieved by changing the location of exhaust fans ad openings. The results help to recommend some guidelines to inform the proposed refurbishment plans of the site.

An exploration of the impact of celebrity on the HIV/AIDS pandemic

The framework we present in this article separates into three generations the celebrity/personality involvement in the AIDS movement that has been steadily building momentum over the past 25 years. We analyze the celebrification of HIV/AIDS and the role of the media in the process. We contend the relationship between celebrity, the public and HIV/AIDS is multipurpose: celebrities maintain a positive public presence between projects while allowing themselves and their supporting fans to feel good about taking on and affecting a meaningful cause. Celebrities are vehicles and embodiments of concern that act as proxies for their various audiences. And this is their power–celebrities are embodiments of their audiences. The awareness that celebrities have brought to the HIV/AIDS epidemic has resulted in better treatment for victims and increased government support for medical research, and yet has also distracted the public’s attention from the scope of the epidemic. It is the third generation of celebrities who are refocusing efforts on worldwide prevention and a cure for HIV/AIDS.
