Polyunsaturated fats in meat from Merino, first- and second-cross sheep slaughtered as yearlings

This study examined the level of long chain omega-3 and omega-6 polyunsaturated fats, the ratio of polyunsaturated fat to saturated fat (PUFA/SFA) and the ratio of omega-6 to omega-3 (n-6/n-3) fat in sheep grown under grazing conditions in Australia. The sheep genotypes used were Poll Dorset_growth × Border Leicester Merino (PDg × BLM), Poll Dorset_growth × Merino (PDg × M), Poll Dorsetmuscling × Merino (PDm × M), Border Leicester × Merino (BL × M) and Merino × Merino (M × M). Loin muscles (Longissimus lumborum) collected from 40 ewe and wether sheep slaughtered at 14 months of age were processed for fatty acid determination. After frozen storage, 20 g samples were minced and a 7 g homogenate was processed for muscle lipid extraction using a chloroform:methanol (2:1) procedure. There was an increase in PUFA/SFA as the proportion of Merino genetics increased in the progeny (second-cross < first-cross < Merino), but this was not shown in the n-6/n-3 ratio. The PUFA/SFA trend appeared to be associated with an increase in the level of total polyunsaturated fats, but not a decrease in the level of total saturated fats. The results demonstrate that there is a need to improve the PUFA/SFA content in first- and second-cross animals which are mainly used for meat production in Australia so as to maintain the healthy lipids in meat. Nutritional manipulation through feeding systems or selection of sires for greater heritability of omega-3 fat deposition may be suitable pathways to elevate the ratio of polyunsaturated fatty acids, and in particular omega-3.

Childhood cruelty to animals : a tri-national study

Childhood cruelty to animals is a symptom of conduct disorder that has been linked to the perpetration of violence in later life. Research has identified several factors associated with its etiology, including social factors. However, no cross-cultural studies on this phenomenon have been reported. This study investigated childhood cruelty to animals in Japan, Australia and Malaysia. Parents of 1,358 children between the ages of 5 and 13 years completed the Children’s Attitudes and Behaviours towards Animals questionnaire (CABTA) which assesses Typical and Malicious Cruelty to animals. Analyses revealed no overall differences between children from these countries on either scale. However, younger boys were more likely to be cruel than younger girls in each country, and younger children in Australia and Japan were more likely to be cruel that older children in those countries. The findings are discussed in relation to previous research, and recommendations for future studies are suggested.

Downside beta and the cross-sectional determinants of listed property trust returns

This study examines the importance of downside beta when seeking to explain variations in listed property trust (LPT) returns in Australia between 1993 and 2005. The results reveal that downside beta outperforms conventional beta and provides higher explanatory power to the cross-sectional LPT return variations. The results also indicate that investors only require a premium for downside risk. However, the explanatory power of downside beta has diminished once the co-kurtosis of LPTs is controlled. Interestingly, the results also reveal that by itself downside beta is unable to fully explain returns in line with strong evidence for momentum and book-to-market ratio. The findings provide additional insights for investors and real estate analysts into the pricing of LPTs.

Hyphenated Australia : putting intercultural identity on the conceptual map

Interculturality and intercultural identity is a local effect of the global movement and mixing of people, and those of intercultural identities constitute the fastest growing sector of the Australian population. In an age of globalisation and diversification, what does identity mean for those situated in-between governing notions of racial/ethnic formations, and how is intercultural identity experienced? For those informed by (at least) two cultures, what does multiculturalism, ethnicity and 'Australianness' mean, and where are these individuals positioned in relation to these structures? These questions have critical implications for the Australian nation. Within Australian discourses, interculturality and intercultural identity, in particular, has historically been excluded, rendered invisible. This dissertation is, therefore, one of facilitating visibility. Using the hyphens as a conceptual tool, I argue that in this age of accelerating globalisation the hyphens both makes visible and is made visible by interculturality. The hyphens is that grey and fluid site of intersection between structures of identity and is characterised by liminality - contestation, uncertainty, fundamentally ambivalence. Experiences of liminality, however, dissolve in any given time, opening up new terrain for creativity. Some of these emerging and creative forms of identity, as instigated by interculturality, are explored. Based on interviews with 20 daughters (and their mothers) from intercultural unions, this dissertation places intercultural identity on the Australian conceptual map and analyses the unique position occupied by those with an intercultural identity in their relationship with governing discursive formations of race/ethnicity, embodiment, nation and culture. In essence, the dissertation is concerned with examining the ways in which discursive identity structures intersect with subjective experience, and with the ways in which those with an intercultural identity negotiate those structures and their social relations. This examination raises the fundamental question: is the modernist notion of the material realities of individual lives reconcilable with the poststructural notion of identity as always located in discourse. This modernist/postmodernist tension permeates the dissertation.

Teacher education and critical inquiry : the use of activity theory in exploring alternative understandings of language and literacy

This paper explores the challenges of espousing a critical pedagogy within the managerial climate that presently shapes teacher education. It argues that current discourses of professionalism are incommensurate with a view of literacy as social practice and that they disregard complex semiotic ecologies in which both school and university students operate. Graduate teachers are constructed as the ‘providers’ of decontextualised literacy skills to school students whose existing communication networks are ignored. Rejecting this narrow view of professional practice, we draw on activity theory to analyse the social configuration of tertiary students’ identities and the textual resources that mediate their professional learning. This kind of research is needed to reveal the contradictions within and between activity systems in which tertiary students participate as well as to construct possible solutions to the contradictions identified.

Teacher education and critical inquiry : the use of activity theory in exploring alternative understandings of language and literacy

This article explores the challenges of espousing a critical pedagogy within the managerial climate that presently shapes teacher education. Current discourses of professionalism are incommensurate with an understanding of the way that literacy practices are grounded in the social worlds in which both school and university students operate. Such discourses construct graduate teachers as the providers of decontextualised literacy skills to school students whose existing communication networks are ignored. We argue that an alternative understanding of professional practice can be developed by focusing on the textual resources university students use to mediate their learning, and by locating their emerging professional identities within the activity systems and meaning-making practices in which they participate.
