Troubling identities: teacher education students` constructions of class and ethnicity

Working with diverse student populations productively depends on teachers and teacher educators recognizing and valuing difference. Too often, in teacher education programs, when markers of identity such as gender, ethnicity, 'race', or social class are examined, the focus is on developing student teachers' understandings of how these discourses shape learner identities and rarely on how these also shape teachers' identities. This article reports on a research project that explored how student teachers understand ethnicity and socio-economic status. In a preliminary stage of the research, we asked eight Year 3 teacher education students who had attended mainly Anglo-Australian, middle class schools as students and as student teachers, to explore their own ethnic and classed identities. The complexities of identity are foregrounded in both the assumptions we made in selecting particular students for the project and in the ways they constructed their own identities around ethnicity and social class. In this article we draw on these findings to interrogate how categories of identity are fluid, shifting and ongoing processes of negotiation, troubling and complex. We also consider the implications for teacher education.

Troubling identities : teacher education students' constructions of class and ethnicity

This paper reports on a research project that explored how student teachers understand ethnic and classed difference as it relates to themselves and their students. Discourses of schooling can shape students ethnic and classed identities, frequently positioning non-mainstream students as 'other' and marginalizing them. Significant numbers of our teacher education students have limited experience of diverse educational settings, having mainly attended white middle-class schools as students and as student teachers. Working with diverse student populations productively depends on teachers recognising and valuing difference. The ways in which they engage with students whose ethnic and classed identities are different from their own is important in creating learning environments that build on and engage with diversity.

In a preliminary stage of the research we asked eight third-year teacher education students to explore their own ethnic and classed identities. The complexities of identity are foregrounded in both the assumptions we made in selecting particular students for the project and in the ways they did (not) think about themselves as having ethnic or classed identities.

In this paper we draw on these findings to interrogate how categories of identity are fluid, shifting and ongoing processes of negotiation: troubling and complex. We also consider the implications for teacher education.

Ian's story : the complex interaction of ethnicity, class and masculinities

In this paper, a narrative is used to convey the complex connectedness that exists between class, ethnicity and masculinity. The story is of Ian, a successful academic who describes himself as Eurasian, and traces his development through parts of his childhood and into his professional career, using what Gough (1994) describes as a 'realistic fiction'. Relevant literature on masculinities and ethnicity is considered. There is some evidence to suggest that Ian has developed a fluid version of masculinity as a result of his Asian-Australian upbringing, and that he expresses different masculinities according to the social settings in which he finds himself. The paper concludes, just as Ian's story does, that masculinity interacts with class and ethnicity. This accords with Connell's (1995) caution that it is dangerous to think that there is a colored masculinity or a working class masculinity, and that the milieux of class and race need to be considered as well.

Re-gendering labour: class and gender determinants of New South Wales electoral behaviour 1930-32

Historians have neglected tbe impact of female enfranchisement on Australian electoral outcomes. This papers employs multivariate analysis to explore electoral behaviour in New South Wales during the Great Depression. It argues that women were less prone to support Labor than men, but that women in paid employment constituted a partial exception to this pattern. In 1932 the conservative parties significantly eroded Labor's working-class support. Part of this success was due to the ability of employers to coerce workers with the threat of dismissal. Female wage earners were particularly vulnerable to this coercion. Conservative electoral appeals recast masculinity in terms of family responsibility rather than class assertion. Conflict in the household economy possibly influenced women to vote against Labor due to its identification with the cause of male breadwinners. Overall female voting behaviour was more stable than that of men and this despite the higb profile of issues that would have been expected particularly to influence female voters.

Serum 25-hydroxyvitamin D, diabetes, and ethnicity in the third national health and nutrition examination survey

OBJECTIVE— To determine the association between serum 25-hydroxyvitamin D (25OHD) and diabetes risk and whether it varies by ethnicity.
RESEARCH DESIGN AND METHODS— We performed an analysis of data from participants who attended the morning examination of the Third National Health and Nutrition Examination Survey (1988–1994), a cross-sectional survey of a nationally representative sample of the U.S. population. Serum levels of 25OHD, which reflect vitamin D status, were available from 6,228 people (2,766 non-Hispanic whites, 1,736 non-Hispanic blacks, and 1,726 Mexican Americans) aged ≥20 years with fasting and/or 2-h plasma glucose and serum insulin measurements.
RESULTS— Adjusting for sex, age, BMI, leisure activity, and quarter of year, ethnicityspecific odds ratios (ORs) for diabetes (fasting glucose ≥7.0 mmol/l) varied inversely across quartiles of 25OHD in a dose-dependent pattern (OR 0.25 [95% CI 0.11– 0.60] for non-Hispanic whites and 0.17 [0.08–0.37] for Mexican Americans) in the highest vitamin D quartile (25OHD ≥81.0 nmol/l) compared with the lowest 25OHD (≥43.9 nmol/l). This inverse association
was not observed in non-Hispanic blacks. Homeostasis model assessment of insulin resistance (loge) was inversely associated with serum 25OHD in Mexican Americans (P ≥ 0.0024) and non-Hispanic whites (P≥0.058) but not non-Hispanic blacks (P≥0.93), adjusting for confounders.
CONCLUSIONS— These results show an inverse association between vitamin D status and diabetes, possibly involving insulin resistance, in non-Hispanic whites and Mexican Americans. The lack of an inverse association in non-Hispanic blacks may reflect decreased sensitivity to vitamin D and/or related hormones such as the parathyroid hormone.

'Class' and political theatre : the case of Melbourne workers theatre

Traditionally, class has been an important category of identity in discussions of political theatre. However, in recent years the concept has fallen out of favour, partly because of changes in the forces and relations of capitalist production. The conventional Marxist use of the term, which defined an individual's class position in relation to the position they occupied in the capitalist production process, seemed anachronistic in an era of globalization. Moreover, the rise of identity politics, queer theory, feminism, and post-colonialism have proffered alternative categories of identity that have displaced class as the primary marker of self. Glenn D'Cruz reconsiders the role of class in the cultural life of Australia by examining the recent work of Melbourne Workers Theatre, a theatre company devoted to promoting class-consciousness, in relation to John Frow's more recent re-conceptualization of class. He looks specifically at two of the company's plays, the award-winning Who's Afraid of the Working Class? and The Waiting Room, with reference to Frow's work on class, arguing that these productions articulate a more complex and sophisticated understanding of class and its relation to politics of race and gender today.

Communicating entrepreneurship and ethnicity in New Zealand

In this paper, we compare entrepreneurship practice of the Maori culture with that of the other five ethnic groups or cultures in New Zealand including European New Zealanders, Europeans, Chinese, Indians and Pacific Islanders. One of the most reported findings in previous GEM reports was that Maori are every bit as entrepreneurial as other ethnicities. Some commentators were surprised by this finding, since Maori collect more than their proportionate share of benefit entitlements. But we have shown that Maori have a history of entrepreneurship and enterprise upon which to draw (Frederick and Henry, 2004). The Maori economy, though small, is "robust and poised for continued expansion", says a recent report by the Institute of Economic Research (NZIER, 2003).

Music video and gendered pleasures in the lives of young women and men

The purpose of this thesis is to explore the cultural and social significance of music video in the lives of a group of young women and men. In so doing the thesis pays particular attention to issues of gender and pleasure. This research examines the interaction of a group of young people with music video in relation to four areas of research. Firstly, the importance of music video in terms of social interaction and the pleasure this entails is explored. Secondly the thesis looks at the ways in which gender is seen by the young people in this study to be established by music video performers. Thirdly, how gender becomes inscribed on the body is explored, and fourthly I examine the process of sexualization of the body. Theoretically this thesis draws upon feminist theory, poststructuralist theory, music video scholarship and educational theories. This eclectic approach has been necessary as this research speaks simultaneously to several distinct areas of scholarship: education, cultural studies and feminism. My research with a young audience of music video took place within a secondary school. Over two semesters I conducted research with two separate classes of Media Studies students who were aged fifteen and sixteen. A total of 49 students were interviewed, however I chose mainly to work with a small group of eleven students - five girls and six boys. The school where I conducted this research is located in a working class suburb of a provincial and industrial Australian city . The young people's social positioning in terms of class and ethnicity has been considered in some depth in relation to the construction of the gendered subject. Methodologically the thesis is skewed towards the audience, and also towards dealing with what is normally unspoken in the research process. For example, much academic research does not include the author of the research as an integral part of that research. In this thesis I include myself in a number of ways: historically, personally and as a feminist. This thesis places a high priority on ethics and the effects of research on those who participate in the research process. The thesis uses a number of research methods: structured interviews, informal conversations, memory-work and written responses to music videos. Generally the research methods used in this thesis have been developed reflexively; that is, they have developed directly in relation to the participants’ reactions, responses, suggestions, interests and comments. The research seeks to demonstrate the place of music video in the lives of the young people who participated in the study. I look at how the young people in this study connect music video to other cultural forms and social interactions. In this way the intertextuality of music video is demonstrated. The research looks at how young viewers 'read' the gender of music video performers, and how this affects their own gendering. The social and cultural meanings which are attached to certain parts of the body are also examined. Theorizing the body in terms of its social meanings is a significant part of this thesis. The research argues that young people often experience music video as pleasurable, and that music video can provide young people with access to powerful speaking positions. This is demonstrated through transcripts of our conversations and interviews, and also through the young people's written comments. However, these powerful speaking positions invariably invoke dominant discourses (homophobia and racism, for example). Thus the disruptive potential of music video is called into question. These dominant discourses are gendered in nature. Pleasure in the text (music video) and cultural inscriptions of gender on the body then, are realized differently for the girls and for the boys in this study. My research into music video, gender and young people has implications for research methodology generally, and for music video scholarship specifically. Music video scholarship to date has rarely focussed upon the audience of this cultural form. My research has certain implications for the ways in which research is currently conducted with young people in relation to popular culture generally, and music video specifically, and gendered subjectivity.

Cosmo girls : new configurations of class and femininity in elite educational settings

In this paper we offer a unique contribution to understandings of schooling as a site for the production of social class difference, by bringing together recent work on middle-class educational identities in neoliberal times (O’Flynn and Petersen 2007, Reay et al 2007, 2008) with explorations of classed femininity from the field of critical girlhood studies (Harris 2004, Ringrose and Walkerdine 2008). Drawing on data generated in two recent research projects in Australia and the UK our aim will be to explore how class mediates the construction of young femininities in the private girls’ school. Our particular focus will be on exploring how articulations of identity within such schools are configured through discourses of mobility and global social responsibility. In line with the broader ‘cultural turn’ in the social sciences (Devine 2005) we discuss class and femininity in this paper in cultural and symbolic terms. We draw on Butler’s (1993) notions of performativity to understand the multiple and processual nature of identity constitution and Bourdieu’s (1987) understandings of class (based on symbolic struggles for capital in social space) to enable us to explore the ‘subjective micro distinctions’ through which class is expressed, embodied and lived; viewing class as a set of fictional discourses that inscribe and produce identities (Walkerdine et al 2001). This understanding of class, as something that is ‘done’ rather than something that ‘we are’, was deemed particularly important in these studies of elite education, for the research was undertaken in schools where class was apparently ‘everywhere and nowhere’, never named or ‘directly known as class’ (Lawler 2005, Skeggs 2004). This underplaying of class identity is often linked to neo-liberalism, and in this paper we would like to link these constructions of ‘the private school girl’ with neoliberal subjectivity by focusing on two main characteristics. First we will consider the notion of mobility, where we will discuss the ways in which these girls constructed themselves as ‘cosmo’ girls (global citizens at ease with traversing national borders) and the ways in which the schools supported this through educational practices which enabled the students and their families ‘to exploit and strategically pursue economic and cultural capital’ (Doherty et al 2009). We will also focus on the struggles that the schools and students encountered as they attempted to juggle these discourses of global mobility with more traditional discourses of privilege (often associated with national boundaries and based within a predominantly British model of schooling steeped in colonial history). Second, we will look at discourses of responsibility, to explore how these girls were incited to take responsibility for themselves and their futures but also to embrace diversity and to commit themselves to social service. We will also examine the competing discourses of instrumentalism and social justice that were at play in these schools.

Sesamin modulation of lipid class and fatty acid profile in early juvenile teleost, Lates calcarifer, fed different dietary oils

Sesamin, a major sesame seed lignan, has diverse biological functions including the modulation of molecular actions in lipid metabolic pathways and reducing cholesterol levels. Vertebrates have different capacities to biosynthesize long-chain PUFA from dietary precursors and sesamin can enhance the biosynthesis of ALA to EPA and DHA in marine teleost. Early juvenile barramundi, Lates calcarifer, were fed for two weeks on diets rich in ALA or SDA derived from linseed or Echium plantagineum, respectively. Both diets contained phytosterols and less cholesterol compared with a standard fish oil-based diet. The growth rates were reduced in the animals receiving sesamin regardless of the dietary oil. However, the relative levels of n-3 LC-PUFA in total lipid, but not the phospholipid, increased in the whole body by up to 25% in animals fed on sesamin with ALA or SDA. Sesamin reduced the relative levels of triacylglycerols and increased polar lipid, and did not affect the relative composition of phospholipid subclasses or sterols. Sesamin is a potent modulator for LC-PUFA biosynthesis in animals, but probably will have more effective impact at advanced ages. By modulating certain lipid metabolic pathways, sesamin has probably disrupted the body growth and development of organs and tissues in early juvenile barramundi.

Changes in oil content, lipid class and fatty acid composition of the microalga Chaetoceros calcitrans over different phases of batch culture

 Abstract
The diatom Chaetoceros calcitrans is a microalgal species used as food for larva in aquaculture for many species worldwide. Chaetoceros calcitrans is an important source of omega 3 long chain (C ≥ 20) polyunsaturated fatty acids (n-3 LC PUFA), chiefly eicosapentaenoic acid (EPA, 20:5n-3). This article reports lipid content, lipid class composition and fatty acid profiles of each lipid class during the growth cycle of batch cultures of C. calcitrans. Total lipid content and the concentration of neutral lipid were highest in the late stationary growth phase (day 12). However, the amount of EPA was highest during the logarithmic growth phase (1.24 pg/cell on day 4). EPA was initially concentrated in the glycolipid fraction, but this fraction decreased during logarithmic growth, coinciding with the increase in neutral lipid. Docosahexaenoic acid (22:6n-3, DHA) (0.91 pg/cell) was reported as a major fatty acid (>10 mg/100 g) in all lipid classes on day 1. DHA was depleted quickly from the neutral lipid and glycolipid classes, but at a slower rate from the polar lipid fraction. This work confirms that C. calcitrans is a good source of lipid, in particular EPA, for larval and adult filter feeders in aquaculture.
