From personal reflection to social positioning: the development of a transformational model of a professional education in midwifery

A transformational model of professional identity formation, anchored and globalized in workplace conversations, is advanced. Whilst the need to theorize the aims and methods of clinical education has been served by the techno-rational platform of 'reflective practice', this platform does not provide an adequate psychological tool to explore the dynamics of social episodes in professional learning and this led us to positioning theory. Positioning theory is one such appropriate tool in which individuals metaphorically locate themselves within discursive action in everyday conversations to do with personal positioning, institutional practices and societal rhetoric. This paper develops the case for researching social episodes in clinical education through professional conversations where midwifery students, in practice settings, are encouraged to account for their moment-by-moment interactions with their preceptors/midwives and university mentors. It is our belief that the reflection elaborated by positioning theory should be considered as the new epistemology for professional education where professional conversations are key to transformative learning processes for persons and institutions.

Moving towards a model of professional identity formation in midwifery through conversations and positioning theory

The disciplines of nursing and midwifery both uphold a powerful oral tradition that can impact upon student learning. Students enrolled in a Graduate Diploma of Midwifery are supervised and assessed by midwives during their placements in midwifery practice settings by a program of 'preceptorship' support and where conversations are innate. Positioning theory, eveloped by Harre and others, is a metaphorical concept in which an individual 'positions' herself/himself within entities of encompassing people, institutions and societies where conversations are conducted either privately or publicly. As construction sites of professional learning, conversations are underpinned by reflective practices.In unravelling conversations, positioning may be applied as an analytical tool by educators to interpret the emerging meanings and themes in their discussions with students, reflective journals by students and in meetings with preceptors/midwives.

Post-migration food habits of sub-Saharan migrants in Victoria: a cross-sectional study

Objective: (i) To describe sub-Saharan African (SSA) post-migration food habits and eating patterns; and (ii) to examine how the food habits of SSA households in Victoria reflect post-migration acculturation.
Design: A cross-sectional survey using a snowball sampling technique. Data on food habits and eating patterns were obtained using semi-structured, face-to-face interviews from November 2001 to April 2002.
Subjects: A total of 139 households of demographically diverse recent migrants from across sub-Saharan Africa.
Setting: Melbourne metropolitan and Melbourne fringes.
Analysis: Data were summarised using descriptive statistics.
Results: SSA migrants and refugees indicated dietary acculturation characterised by three processes: substitution, supplementation and modification of recipes. They experienced difficulty locating their traditional foods, in particular, African vegetables (34.2%), unprocessed maize meal (29.1%), camel milk (23.1%) and maize grain (13.7%). The new foods adopted since arrival were pizza, breakfast cereals and fast foods, but also included new fruits and vegetables. Takeaway food such as Pizza Hut or McDonalds featured prominently in the SSA post-migration diet. Reasons for eating out were favourite food (48.3%), routine family outing (38.3%), special occasion (33.3%) and no time to cook (25%). A significant change in meal pattern was the inclusion of breakfast, although 21% reported skipping breakfast.
Conclusion: Many of the observed dietary changes were not consistent with good health and may predispose this population to rapid weight gain and chronic disease. Rapid modernisation and the Anglo-Australian culture interact in a complex way with traditional eating and socialisation practices of SSA migrants. Understanding these forces can allow effective health promotion and community development strategies to be developed for the future health of SSA migrants and their communities.

Obesity and undernutrition in sub-Saharan African immigrant and refugee children in Victoria, Australia

The study assessed the anthropometric status of 337 sub-Saharan African children aged between 3-12 years who migrated to Australia. These children were selected using a snowball sampling method stratified by age, gender and region of origin. The prevalence rates for overweight and obesity were 18.4% (95%CI: 14 - 23%) and 8.6% (95%CI: 6% -12%) respectively. The prevalence rates for the indicators of undernutrition were: wasting 4.3% (95%CI: 1.6%-9.1%), underweight 1.2% (95%CI: 0.3%-3.0%), and stunting 0.3 (95%CI: 0.0%-1.6%). Higher prevalence of overweight/obesity was associated with lower household income level, fewer siblings, lower birth weight, western African background, and single parent households (after controlling for demographic and socio-economic factors). Higher prevalence rates for underweight and wasting were associated with lower household income and shorter lengths of stay in Australia respectively. No effect was found for child's age, gender, parental education and occupation for both obesity and undernutrition indices. In conclusion, obesity and overweight are very prevalent in SSA migrant children and undernutrition, especially wasting, was also not uncommon in this target group.

Mobile subjectivities positioning the nonunirary self in critical feminist and postmodern research

Most scholarly work is written from the perspective of the author being a unitary subject occupying a sole, rational, and unified position. This article argues that scholarship may be enhanced by the author adopting multiple subject positions as a methodological framework. Such an adoption is advantageous in working against the romance of the notion of a single truth while also maintaining teleological values congruent with critical and feminist agendas. This article outlines the conceptual development of this methodological framework, the rationale for its development, an explication of the concept of multiple subjectivity, and an exemplar of its application within nursing research.

Fat, rich and beautiful: changing socio-cultural paradigms associated with obesity risk, nutritional status and refugee children from sub-Saharan Africa

There has been an increase in Australia's intake of refugees and migrants from sub-Saharan Africa over the last two decades. These refugees have been exposed to nutritional risks prior to migration, which, together with changes associated with acculturation, impact on their health and nutritional status post-migration. However, there is a paucity of data in Australia that has examined the health and nutritional status of this ethnic minority in Australia. Despite basic research assessing the nutritional status of children, none have specifically concentrated on the health and nutritional situation of sub-Saharan refugee children. In the absence of such studies, this paper explores issues relating to obesity in sub-Saharan African refugee children within a cultural and public health framework. We begin by outlining the history of obesity and its cultural meaning. We then move to a consideration of predisposing factors for obesity and how these factors translate into obesity risk contexts of sub-Saharan refugees post-migration. We argue there are a number of key challenges related to culture and the relationship between socio-economic factors post-migration that require addressing by health professionals, dieticians and health educators to ensure the delivery of successful health outcomes.

Guanxi in a sub-national cross-cultural setting

This paper explores whether Chinese relationship building, Guanxi, is effective in crosscultural sub-national relationships. Derived from research into Sino-Australian Sister City Type Relationships and using material gathered through interviews in China and Australia, a modified Institutional Guanxi conceptual model has been developed. Some propositions are developed to link the components of the Guanxi conceptual model. Different methodologies are explored to determine the most effective way to test the hypotheses in a cross-cultural environment, and future research is outlined.

The positioning of mathematics in an environmental thematic curriculum

With a crowded curriculum, many primary schools attempt to integrate their key learning areas. One primary school in a large regional city has taken this a step further. Using the ’environment’ as the overarching theme, the key learning areas are interwoven into the teaching of the environment. This has presented some issues when attempting to teach English and Mathematics. These issues and the way the school and teachers solve them are documented in this case-study.

A computational framework for nucleic acid sub-sequence identification

Identification of nucleic acid sub-sequences within larger background sequences is a fundamental need of the biology community. The applicability correlates to research studies looking for homologous regions, diagnostic purposes and many other related activities. This paper serves to detail the approaches taken leading to sub-sequence identification through the use of hidden Markov models and associated scoring optimisations. The investigation of techniques for locating conserved basal promoter elements correlates to promoter thus gene identification techniques. The case study centred on the TATA box basal promoter element, as such the background is a gene sequence with the TATA box the target. Outcomes from the research conducted, highlights generic algorithms for sub-sequence identification, as such these generic processes can be transposed to any case study where identification of a target sequence is required. Paths extending from the work conducted in this investigation have led to the development of a generic framework for the future applicability of hidden Markov models to biological sequence analysis in a computational context.

The positioning of practitioners in vocational education and training research

What is the status and role of research in VET reform? How are the views of practitioners positioned in VET research and reform? What access do VET practitioners have to research that empowers them to critique current policy and practice? This paper explores the sequestions drawing on literature and also on my experience as a VET practitioner and researcher. The national VET research strategy supports a substantial research effort to inform policy and practice. However, in a complex and unstable VET environment, funded research focuses on implementation, rather than critique, of current directions. I argue that the complexity of the VET system gives rise to new research problems, and that VET practitioners have knowledge and insight to offer in exploring these problems. But I question the extent to which current VET consultation and research processes incorporate the views of practitioners. I illustrate these issues by providing a brief overview of my PhD research project, currently being conducted through the Faculty of Education, Deakin University. This project explores the proposition that the language form typically used in official national VET texts is representative of, and constructive in, unequal power relationships.

A comparative study of computational value in visual cues used in positioning 3D objects

This paper explores the comparative computational values of using a variety of visual cues in 3D environments. The authors reflect upon the possible repercussions of computationally less expensive visual cues on users' ability to efficiently and accurately interact with three-dimensional images. This study compares the effectiveness of expensive soft shadows against less expensive hard shadows and expensive partial-occlusion (obtained by semi-transparent surface) against less expensive occlusion on users' ability to accurately position objects in imminent contact with other objects in a three-dimensional environment.
