Prevalence of obesity and the relationship between the body mass index and body fat : cross-sectional, population-based data

Background: Anthropometric measures such as the body mass index (BMI) and waist circumference are widely used as convenient indices of adiposity, yet there are limitations in their estimates of body fat. We aimed to determine the prevalence of obesity using criteria based on the BMI and waist circumference, and to examine the relationship between the BMI and body fat.

Methodology/Principal Findings: This population-based, cross-sectional study was conducted as part of the Geelong Osteoporosis Study. A random sample of 1,467 men and 1,076 women aged 20–96 years was assessed 2001–2008. Overweight and obesity were identified according to BMI (overweight 25.0–29.9 kg/m2; obesity $30.0 kg/m2) and waist circumference (overweight men 94.0–101.9 cm; women 80.0–87.9 cm; obesity men $102.0 cm, women $88.0 cm); body fat mass was assessed using dual energy X-ray absorptiometry; height and weight were measured and lifestyle factors documented by self-report. According to the BMI, 45.1% (95%CI 42.4–47.9) of men and 30.2% (95%CI 27.4–33.0) of women were overweight and a further 20.2% (95%CI 18.0–22.4) of men and 28.6% (95%CI 25.8–31.3) of women were obese. Using waist circumference, 27.5% (95%CI 25.1–30.0) of men and 23.3% (95%CI 20.8–25.9) of women were overweight, and 29.3% (95%CI 26.9–31.7) of men and 44.1% (95%CI 41.2–47.1) of women, obese. Both criteria indicate that approximately 60% of the population exceeded recommended thresholds for healthy body habitus. There was no consistent pattern apparent between BMI and energy intake. Compared with women, BMI overestimated adiposity in men, whose excess weight was largely attributable to muscular body builds and greater bone mass. BMI also underestimated adiposity in the elderly. Regression models including gender, age and BMI explained 0.825 of the variance in percent body fat.

Conclusions/Significance: As the BMI does not account for differences in body composition, we suggest that gender- and age-specific thresholds should be considered when the BMI is used to indicate adiposity.

Homework through the eyes of children : what does visual ethnography invite us to see?

Whilst the notion of children’s rights and an entitlement to express their views and participate as global citizens is threaded throughout the international policy field, children’s perspectives on the near ubiquitous practice of homework, and its effects on their daily lives and learner subjectivities, remain under-researched. Drawing on the Bourdieuian concepts of practice, habitus, capital and field, this article develops a cross-cultural analysis of homework practices in Australia, Denmark and Britain to make visible the embodied habitus and agentic possibilities shaping the reproduction of educational advantage and disadvantage for variously located students. Using video data generated by children in primary schools, the article explores children’s visual representations of their compliance and resistance to homework’s regulatory functions. It demonstrates the affordances of visual ethnographic methods as a form of participatory research with children which foregrounds students’ experiences and opinions and makes visible the inclusionary and exclusionary effects of homework on children in diverse socio-cultural settings.

A labour of love: mothers, emotional capital and homework

This paper develops a new analysis of homework by building on feminist scholarship which documents the invisible labour done by women in support of their children's education. While numerous studies have examined the relationship between homework and achievement, little attention has been paid to the largely gendered and potentially stressful nature of ‘parental involvement’. The analytic focus in this paper is on the complex emotional and pedagogical dimensions of homework and the ways it is shaped by socio-cultural contexts. Videotaped homework interactions between one working-class and two middle-class mothers and their children are examined using Bourdieu's concepts of habitus and capital. The analysis distinguishes between productive pedagogical relationships and those that promote extensive anxiety and are counterproductive to learning. The paper argues that the reserves of cultural and emotional capital required for homework completion are significant and that class position does not necessarily guarantee the ways in which these capitals are mobilised.

Embodied choreography and performance of gender

Norms of fitting embodied behaviour for males and females, as promoted in Australian public arenas of popular culture and the everyday, disempower and marginalise those not inclined to embody in gendernormative and heteronormative ways.

This thesis engages with concepts of embodiment as meaning the manner of physical deportment in which a physical practice is performed, and with concepts of gender as social constructions of femininity and masculinity. It investigates the demands and implications of dominant norms of gender embodiment for those whose embodied inclinations do not fit comfortably with such dichotomous models. It interrogates gender inequitable machinations of education and performance arts disciplines by which educators and arts practitioners train, teach, choreograph, and direct those with whom they work, and theorises ways of broadening personal and social notions of possible, aesthetic, and acceptable embodiment for all persons, regardless of biological sex or sexual orientation.

This research is grounded in two major qualitative methods of enquiry. First, through an autoethnographic lens, it focuses on the impacts that social constructions of masculinity have on me, both as a person in the everyday and as a performance arts practitioner/educator. Through writing, illustration, choreography, and performance, as well as interviews with 3 members of my family, I analyse the delicacy of the relationship between social control/surveillance and personal agency over my embodiment of gender. Second, through empirical ethnographic fieldwork with some 400 high school students and 160 educators and performance arts practitioners, I utilise a combination of performance, discussion, practical workshop, and avenues for anonymous response to explore the potential of the performance arts in challenging inequitable notions of gender embodiment.

My findings demonstrate that inherent ideologies in dominant discourses regarding the execution and display of feminine and masculine embodiment continue to work, overtly and covertly, as definitive and restrictive barriers to the realm of possibilities of embodied gender expression and appreciation in the everyday and in the performance arts. This thesis recommends drawing individuals’ attention to embodied gender inequities and enculturation processes, not ordinarily critiqued within mainstream society, as a key toward safeguarding the well-being of those whose embodied performance inclination is at odds with prescribed norms of behaviour. Performance arts arenas are powerful sites in which such deconstructive work can occur, both cognitively and practically. However, as this thesis explores and illustrates, performance arts practitioners/educators need to first scrutinise existing and hidden inequities regarding the embodiment of gender within their own habitus, perspectives, taste, and practices.

A fish out of water? Legal practitioner - practitioner teacher? Bourdieu, the legal field and the scholarship of teaching in practical legal training

It is surprising to discover during early doctoral research that there is a paucity of Australian scholarship using Bourdieu’s theoretical tools in the field of law, and in the sub-field of post-graduate pre-admission practical legal training. This article introduces Bourdieu’s conceptions of habitus, field, categories of capital, symbolic violence, and misrecognition. It describes how Bourdieu applied these tools to identify structural hostility between legal academics and practitioners, and the struggles for control in the field of law. Review of three North American studies that used Bourdieu’s theories follows, involving law students’ habitus in transition, class stratification in legal education, and gender stratification in law firm partnerships. Drawing on three internally connected ‘moments’ necessary to use Bourdieu’s tools, together with four critical questions concerning teachers’ engagement with the scholarship of teaching, this article identifies new questions for investigation. These questions will frame further research to discover whether the objective structures of the practical legal training field and the habitus of legal practitioners constrains them to act as ‘fish out of water’ in the context of a scholarship of teaching.

Negotiating the university environment : how first year students learn about university processes

This paper is an attempt to make sense of the literature about how new university students develop an understanding of those university processes that are essential to their academic success. Whereas traditionally there has been a tendency to regard students as deficient if they had transition difficulties, such an approach fails to recognise the complexity of the process and the role of the habitus, as explored by Bourdieu (1993), in rendering this task even more difficult for some students. The literature highlights the need for further research. We suggest the need to do so with regard to the complexity of students' experiences and the need to better appreciate the role of emotional or affective influences to that end. We also suggest that Bourdieu's concepts, especially those concerning habitus, would provide a sound foundation for the suggested research.

Learning in social action : the informal and social learning dimensions of circumstantial and lifelong activists

This paper explores the informal and social learning dimensions of activists as they learn skills and knowledge through participating in social action. In doing this I draw on Lave and Wenger's epistemology of situated learning and Bourdieu's theory of "habitus". I argue activists learn an array of community development skills in the social environment of activism. I claim activists' learning is cognitive, embodied and situated in practice. This paper is based on empirical research in Australia, where in-depth interviews were conducted with activists to uncover their important pedagogy. It explores the learning dimensions of two groups of activists. "Lifelong activists" who have generally been involved in student politics and have participated in activism over many years, and "circumstantial activists" who become involved in protest due to a series of life circumstances. This paper claims that while both groups' learning is social and informal, lifelong activists tend to develop their skills incrementally by being involved in the fertile site of student politics. On the other hand, circumstantial activists, not having had the benefit of early immersion in a community of practice, are rapid learners. They are frequently taken out of their comfort zone as activists and need to acquire new knowledge and skills urgently in order to practise effectively. Some circumstantial activists remain on the periphery of activism and never fully immerse themselves in the practices of activism. I argue there is much to be gained from understanding learning in social action, an epistemology of adult learning which deserves greater prominence in current adult education discourse.

Intercultural pathways for knowledge Transfer within academic mobility

This paper focuses on academic mobility with the view of examining knowledge flows and effective cultural pathways for knowledge transfer. Its main objective is to set up the theoretical parameters for exploring intercultural encounters within academic mobility with an additional goal of revealing underlining conditions for effective intercultural knowledge transfer and creation. Academic mobility describes global mobilities of tertiary students and university staff and refers to a growing phenomenon worldwide. It creates additional possibilities for exploring the enabling conditions for the intercultural knowledge flows. Academic migrants have been acknowledged as important agents of intercultural knowledge transfer, interchange and, ultimately, knowledge creation. This paper is guided by a hypothesis that cosmopolitan dispositions can create preconditions for successful knowledge transfer in everyday intercultural interactions in academia. In this paper, theoretical notions and ideas are discussed to provide a foundation for designing an ethnographic research which will seek to analyse empirical manifestations of emerging cosmopolitanism. Some preliminary findings of a pilot study are also analysed.

River flows and profit flows: the powerful logic driving local news

The importance of local news is gaining traction with industry and in journalism scholarship. But there is a need for careful analysis of what it means to be “local” and how we might theorise the role and place of news organisations and journalists who serve local audiences. This paper draws on three qualitative case studies of local newspapers serving small towns and cities in Australia to generate concepts that can be used to deepen understanding about this form of news. Our research highlights that to be local is practical and embodied. It requires individuals, groups, organisations or institution to be anchored in a particular locale and have in-depth understanding of that place that has developed over time. We extend the scholarship of Pierre Bourdieu to suggest this may be understood as local habitus—a powerful set of dispositions and practical logic developed within a place—that the small newspaper is inherently tied to. Reading a newspaper is part of one's local habitus while an individual who possesses it in the journalistic field may have a significant advantage in their day-to-day practices. We suggest this theoretical lens can offer rich insights into the future of local news production across the western world.

Evoking and provoking Bourdieu in educational research

This paper provides an introduction to this special issue of the Cambridge Journal of Education on ‘Evoking and provoking Bourdieu in educational research’. In the course of providing a critical synopsis of each paper, we consider how and why the authors work with and after Bourdieu, both evoking and provoking his thinking tools (particularly field, capital and habitus, but also doxa, misrecognition and illusio) and his methodological disposition that rejects ‘epistemological innocence’. We note that Bourdieu himself invited such provocation and that this is especially needed as the social continues to change, given the new spatialities of globalisation and growing social and economic inequalities. That is, we acknowledge that the empirical and the theoretical are always imbricated in each other, a theme pursued throughout the collection.

Educating for futures in marginalized regions: a sociological framework for rethinking and researching aspirations

'Raising aspirations' for education among young people in low socioeconomic regions has become a widespread policy prescription for increasing human capital investment and economic competitiveness in so-called 'knowledge economies'. However, policy tends not to address difficult social, cultural, economic and political conditions for aspiring, based in structural changes associated with globalization. Drawing conceptually on the works of Pierre Bourdieu, Raymond Williams, Arjun Appadurai and authors in the Funds of Knowledge tradition, this article theorizes two logics for aspiring that are recognizable in research with young people and families: a doxic logic, grounded in populist-ideological mediations; and a habituated logic, grounded in biographic-historical legacies and embodied as habitus. A less tangible third 'logic' is also theorized: emergent senses of future potential, grounded in lived cultures, which hold possibility for imagining and pursuing alternative futures. The article offers a sociological framework for understanding aspirations as complex social-cultural phenomena, and for capacitating emergent and hopeful aspirations through school- and community-based research and dialogue. © 2013 Philosophy of Education Society of Australasia.

International education, the formation of capital and graduate employment : Chinese accounting graduates’ experiences of the Australian labour market

Since the late 1970s, international education has steadily gained in popularity in China.An emerging middle class seeks to strengthen its position in China’s rapidly stratifyingsociety under its socialist market economy with the shift from wealth creation for all towealth concentration for a few. Previously, a foreign qualification was considered apassport to success in either the host or home country’s labour market. But the growingpopularity of overseas study, coupled with the massification of the Chinese highereducation, means Chinese international students are seeking to distinguish themselvesin an increasingly competitive global labour market. This longitudinal study of internationalgraduates, backgrounded by Australian employer perceptions, examines thejourneys of 13 Chinese accounting graduates as they attempt to transition from anAustralian university into the Australian labour market. Bourdieu’s thinking tools offield, capital, disposition and habitus are utilised to consider how different cultural,social and linguistic capitals inform employer understandings of ‘employability’ meantChinese accounting graduates significantly adjusted their life goals.

‘Get foot in the door’: International students' perceptions of work integrated learning

Work-integrated learning (WIL) is regarded as an important vehicle to assist students’ development of relevant professional skills, knowledge and attributes that can enhance their employability. WIL arrangement for international students is a challenging issue for institutions, international students themselves as well as other related stakeholders. While there is an emerging body of literature that examines WIL for international students, how the value of WIL is perceived by this cohort is little known. This paper responds to this dearth of the literature by exploring the different meanings that international students in the vocational education and training sector attach to WIL. Using Bourdieu’s thinking tools of capitals and habitus to interpret interview data from 105 international students, this paper shows that WIL is seen to not only add value to student learning, career aspiration and employability but also transform and enhance their symbolic and social capitals. The paper underscores the instrumental, symbolic and developmental meanings that international students associate with WIL. In particular, it highlights the reciprocal relationship between students’ development of vocational ‘being’ and personal ‘being’ through WIL.
