Traffic-related air pollution and health co-benefits of alternative transport in Adelaide, South Australia.

BACKGROUND Motor vehicle emissions contribute nearly a quarter of the worlds energy-related greenhouse gases and cause non-negligible air pollution, primarily in urban areas. Changing peoples travel behaviour towards alternative transport is an efficient approach to mitigate harmful environmental impacts caused by a large number of vehicles. Such a strategy also provides an opportunity to gain health co-benefits of improved air quality and enhanced physical activities. This study aimed at quantifying co-benefit effects of alternative transport use in Adelaide, South Australia. METHOD We made projections for a business-as-usual scenario for 2030 with alternative transport scenarios. Separate models including air pollution models and comparative risk assessment health models were developed to link alternative transport scenarios with possible environmental and health benefits. RESULTS In the study region with an estimated population of 1.4 million in 2030, by shifting 40% of vehicle kilometres travelled (VKT) by passenger vehicles to alternative transport, annual average urban PM2.5 would decline by approximately 0.4μg/m(3) compared to business-as-usual, resulting in net health benefits of an estimated 13deaths/year prevented and 118 disability-adjusted life years (DALYs) prevented per year due to improved air quality. Further health benefits would be obtained from improved physical fitness through active transport (508deaths/year prevented, 6569DALYs/year prevented), and changes in traffic injuries (21 deaths and, 960 DALYs prevented). CONCLUSION Although uncertainties remain, our findings suggest that significant environmental and health benefits are possible if alternative transport replaces even a relatively small portion of car trips. The results may provide assistance to various government organisations and relevant service providers and promote collaboration in policy-making, city planning and infrastructure establishment.

Genetically modified food in the news: media representations of the GM debate in the UK.

This paper analyses a corpus of articles on GM crops and food which appeared in six UK newspapers in the first three months of 2004, the year following the GM Nation? debate (2003). Using the methods of critical discourse analysis we focus on how specific and pervasive representations of the major stakeholders in the national debate on GM—the British public, the British government, the science of GM, and biotechnology companies—served significant rhetorical functions in the controversy. Of particular significance was the pervasive representation of the British public as uniformly opposed to GM crops and food which served rhetorically to position the British government as undemocratic and as being beholden to powerful political and economic interests. Of significance also in our analysis, is how the science of GM farming itself became a highly contested arena. In short, our analysis demonstrates how the GM debate was represented in the newsprint media as a “battleground” of competing interests. We conclude by considering the possible implications of this representation given the increasing emphasis placed on the importance of deliberative and inclusive forms of science policy decision-making.

Tracking Depression-Related Mental Health Literacy Across South Australia: A Decade of Change:

Objective: The aim of the present study was to measure and compare levels of depression-related mental health literacy in South Australia across three points in time: 1998, 2004, and 2008. Method: Participants were those recruited for the 1998, 2004, and 2008 South Australian Health Omnibus Surveys. Comparisons were made across overall levels of depression-related mental health literacy as well as between responses to independent questionnaire items. Results: A significant improvement was found in the overall measure of depression-related mental health literacy between 1998 and 2004 and this was consolidated in 2008. Some discrete changes in literacy were found between 2004 and 2008, with improvements recorded across some demographic groups and in participants’ ability to accurately classify symptoms. Participants in 2008, however, were significantly less likely to endorse providers or treatments as ‘helpful’ than in 2004. Conclusions: Although knowledge and understanding of depression have improved significantly and stabilized since 1998, patient confidence in both mental health therapists and treatment options fell between 2004 and 2008, although it is still greater than in 1998.

Cobenefits of replacing car trips with alternative transportation: a review of evidence and methodological issues.

It has been reported that motor vehicle emissions contribute nearly a quarter of world energy-related greenhouse gases and cause nonnegligible air pollution primarily in urban areas. Reducing car use and increasing ecofriendly alternative transport, such as public and active transport, are efficient approaches to mitigate harmful environmental impacts caused by a large amount of vehicle use. Besides the environmental benefits of promoting alternative transport, it can also induce other health and economic benefits. At present, a number of studies have been conducted to evaluate cobenefits from greenhouse gas mitigation policies. However, relatively few have focused specifically on the transport sector. A comprehensive understanding of the multiple benefits of alternative transport could assist with policy making in the areas of transport, health, and environment. However, there is no straightforward method which could estimate cobenefits effect at one time. In this paper, the links between vehicle emissions and air quality, as well as the health and economic benefits from alternative transport use, are considered, and methodological issues relating to the modelling of these cobenefits are discussed.

Career transitions and identity: a discursive psychological approach to exploring athlete identity in retirement and the transition back into elite sport

Athletes’ career transitions have received widespread research attention and have been identified as potentially distressing for athletes. Yet, the transition back into elite sport following retirement, although rare, has not been a focus of research attention. The concept of athlete identity has been widely researched within sport psychology to give insight into the varied experiences of athletes, especially in relation to the transition out of elite sport. Accordingly, identity may provide additional insight into the transition back into competing at an elite level. Through adopting a discursive psychological approach to the examination of 84 newsprint media representations involving athletes and career transitions, the present study aims to explore dominant social understandings around athlete identity and the choices athletes make to compete (or not) in sport. In doing so, the aim is to add to existing literature around athlete identity and gain insight into the social contexts in which athletes choose to transition back into elite sport, as well as to extend the existing discursive psychological literature of sport and exercise into areas of athlete identity, career transition and the media. Returning to compete in elite sport was routinely depicted in media accounts as something that is not chosen, but as driven by emotion, compulsion and a need to play. Such representations of athletes construct their identity as necessarily motivated by emotion and compulsion.

‘Take ownership of your condition’: Australian women’s health and risk talk in relation to their experiences of breast cancer

Western understandings of breast cancer are primarily shaped both by neo-liberal, individual-oriented approaches to health and illness and by ‘consumer-led’ health movements. In this ‘healthist’ context, diagnosis of breast cancer typically marks a crisis in women’s lives, which may prompt them to account for the development of the illness and reposition themselves as self-governing individuals who have control over their health and who can manage future ‘risks’. We present a thematic discourse analysis of interviews conducted in 2012 with 27 women across Australia who have had breast cancer. Using the lenses of ‘healthism’ and ‘risk management’ in this analysis, we identified a cultural discourse of ‘individual responsibility and empowerment’. Women utilised this discourse while ‘accounting’ for their illness by engaging in ‘health talk’ and ‘risk talk’. While many women emphasised the shock of the diagnosis in light of having been ‘always healthy’, others expressed the inevitability of ‘risk’ on the basis of individual behaviours or genetic history. This discourse provided women one way to explain and make sense of their illness, potentially enabling them to cope with the fear and uncertainty of breast cancer. Drawing on this discourse, women could also position themselves in socially desirable and empowered ways as responsible health consumers, as self-governing and as taking responsibility in dealing with the illness and remaining vigilant for recurrence. We discuss how this neo-liberal approach can be empowering, but also has the effect of positioning women as primarily responsible for managing their health and their illness.

‘If you grow them, know them’: Discursive constructions of the pink ribbon culture of breast cancer in the Australian context

The ‘pink ribbon culture’ dominates understandings of breast cancer in Western societies. We describe this as an ‘illness culture’, consisting of neoliberal discourses and practices, which construct the breast cancer experience. We take a feminist post-structuralist approach to review current breast cancer lay materials available to women in Australia, to examine how breast cancer is discursively constructed within this context. Further, we consider how women with breast cancer are positioned and what the implications are for women’s lives. We discuss neoliberal discourses of ‘individual responsibility and empowerment’ and ‘optimism’, and the central practices that focus on individual health behaviours and survivorship. This illness culture has productive and restrictive effects for women’s subjectivity. Whilst women are positioned as ‘empowered’ regarding their health, this comes at the price of self-regulation and responsibility. Support and information additionally reposition women in feminine, heteronormative ways, whilst excluding women who do not fit narrow cultural stereotypes.

Online Research Methods in Psychology: Methodological Opportunities for Critical Qualitative Research

This special issue showcases the contributions of mostly early career researchers to illustrate the methodological opportunities and challenges that arise in doing critical qualitative research on the Internet. As we discuss, the articles included in this special issue demonstrate innovative qualitative methods that can be applied to Internet research and the steps that need to be taken to conduct rigorous and ethical qualitative research, from a critical psychological perspective. This special issue focuses on a range of methodological issues that can arise while conducting qualitative research online. The authors are seen to acknowledge the power relations that shape online spaces and relationships, and to reflexively and continually consider their roles in data collection or generation. The articles presented in this special issue also highlight ways in which critical qualitative researchers can innovatively negotiate the ethical issues that can occur within a dynamic context, and challenge the status quo through conducting this type of research. Online spaces continually change and present ongoing opportunities and challenges for researchers, yet, this special issue illustrates how critical qualitative researchers are well equipped to continue developing this line of research.

Barriers and facilitators to effective type 2 diabetes management in a rural context: A qualitative study with diabetic patients and health professionals

Although effective type 2 diabetes management is essential for the prevention of complications, it is rarely carried out. Type 2 diabetes deaths in rural areas are higher than in metropolitan areas. A focus group (n = 8) and telephone interviews with patients (n = 10), and telephone interviews with health professionals (n = 18) in rural areas were conducted to examine this issue in a rural context. Inductive thematic analysis was used to generate 13 themes of barriers and facilitators to type 2 diabetes management at intrapersonal (denial of the illness, motivation, knowledge and skills and lack of time), interpersonal (stress and relationships), organisational (access to recommended foods, transport, health professionals, and exercise options) and societal (engagement and societal attitudes) levels of influence. Across all themes, participants highlighted the difficulty of maintaining management behaviours.

Accountability, monitoring and surveillance: Body regulation in elite sport

Regulation of athletes’ bodies is commonplace in sporting environments, despite evidence that athletes have a higher risk of developing disordered eating than non-athletes. This article explores how athletes’ bodies are regulated in practice, building on examinations of body surveillance in other contexts. Over 40 interactions occurring during body monitoring are analysed. Athletes, pre-emptively or following an explicit request, accounted for their body regulatory behaviours, also working to produce positive athlete identities. Failing to produce an account of improvement was interactionally problematic, making visible athletes’ accountability to the institute to regulate their bodies. Implications of body regulatory practices are discussed.
