This project will produce animations in order to increase understandings of safe sex practices and address low perceptions of personal risk among two of the most vulnerable groups to HIV infection in Thailand. The animations will be incorporated into a prevention outreach program via Ipods, mobile phones and mobile-based portable devices to men who have sex with men (MSM) in their 'hide-outs', that is, parks, clubs and public toilets and male sex workers (MSW) in sex venues such as brothels, go-go bars and beats. To produce these animations, the project is first researching the sexual practices of MSM and MSW because of the lack of any substantive investigation of their social and sexual networks. This use of technology, informed by social research rather than behavioral studies, offers new possibilities to stem rapidly rising infection rates because it takes into account the diverse MSM and MSW identities. Overall, an estimated one- fifth (21%) of new HIV infections in Thailand occur in men who have unsafe sex with men. This disquieting increase highlights the fact that MSM are not adequately reached through HIV prevention programmes, most likely because little is known about their particular situations, contexts and practices.

The literature review is fundamental to the doctoral enterprise of academic disciplines, yet research into how the doctoral literature review is learned, taught or experienced is limited. Responding to an apparent under-examination of the literature review as a critical feature of doctoral learning, this thesis investigates the doctoral literature review process as experienced by American and Australian doctoral candidates, doctoral supervisors and academic librarians. The research followed a qualitative approach shaped by two questions: "How is the doctoral literature review process learned?" and, "What is learned by doing a doctoral literature review?" Data were generated from in-depth interviews conducted with 42 participants in education, nursing and the physical and biological sciences. Critical literacy, critical pedagogy and critical information literacy provided frameworks for interpreting participants‘ experiences and perspectives on literature reviewing practices, disciplinary influences and mutually associated doctoral literacies.

The doctoral literature review is traditionally considered to be two segregated events—literature seeking and writing in an academic genre. The study findings challenge this perspective, proposing instead that doctoral literature reviewing is a complex, comprehensive process characterised by interdependent activities in a cycle of gathering, reflecting upon and synthesising literatures. Moreover, these findings indicate that, by engaging with disciplinary literatures and the literature review process, doctoral researchers become familiar with an array of critical doctoral literacies—disciplinary literacy, information literacy and reading and writing literacies. Thus, the doctoral literature review can be conceptualised as a pedagogy through which candidates acquire the lived practices and craft skills of disciplinary-specific research; learn to manage large bodies of information, literature and knowledge; and learn to read and write as scholars in their disciplines.

This project reconceptualises traditional perspectives on doctoral literature reviewing and recommends further exploration into its pedagogical potential. By approaching the doctoral literature review as a pedagogical process, the inquiry attempts to unpack literacies embedded within the doctoral enterprise, thereby exposing them as explicit aspects of doctoral learning. Becoming aware of the interrelatedness of critical doctoral literacies can mobilise supervisors, librarians and candidates to exploit the literature review process more fully. Ultimately, this research contributes to an international focus on a central feature of the doctorate and, as such, more broadly informs and supports doctoral pedagogy, particularly for those involved in American and Australian doctoral education.

In this thesis, a folio comprising a major dissertation and three elective tasks, issues including masculinity(ies), identities, leadership and academics’ work practices are considered against a backdrop of change in the higher education sector. Narrative research methods are applied throughout the folio. The first elective, a discussion and commentary arising from an interview with an experienced practitioner in gender education, amounts to a feasibility study for the dissertation, whereas the second elective experiments with the use of computer mediated communication as a means of interviewing a small number of male academics about their inclusive teaching practices. Primarily curiosity-driven research, the conclusion is drawn that computer mediated communication, if used at all, ought provide a complementary, not primary means of data collection. The third elective conveys the life story of an Asian-Australian academic who expresses different masculinities according to the social settings in which he finds himself. The conclusion is made that there is neither a single colored masculinity nor a single working class masculinity. The milieux of race and class need to be considered together. The research described in the major dissertation was undertaken with a group of eleven male academics from a number of rural and metropolitan universities – men who were thought by their colleagues and peers to practice collaborative approaches to leadership. Whereas the majority of the men practised what could be described as transformational approaches to leadership, a small number exploited the process of collaboration mainly for their own protection. Very few of the men engaged in discourses of gender. One of the principal conclusions reached in the paper is that there are ramifications for future leadership training that universities offer so that it becomes more relevant and socially inclusive. Another main conclusion relates to the intimidation reported by some of the men in the study, and that there are implications for universities in the way they protect their employees from such incidents. A third significant conclusion is that there is some way to go before gender is integrated into the discourse of male academics. Until this can occur, limited opportunities exist for alliances to be formed between most male academics and feminist academics for the advancement of socially just workplaces.

Global and Asian aquaculture have witnessed a ten-fold increase in production from 1980 to 2004. However, the relative percent contribution to production of each of the major commodities has remained almost unchanged. For example, the contribution of freshwater finfish has declined from 71 to 66 percent in Asia but has remained unchanged globally over the last 20 to 30 years. This fact has dictated trends in the use of fish as a feed for cultured stocks. The growth in the sector has gone hand in hand with an increasing dependence on fish as feed, either directly or indirectly. In a number of countries in the Asia-Pacific region, the aquaculture sector has surpassed the capture fisheries sector in its respective contributions to the gross domestic product (GDP). Aquaculture’s increased contribution to national GDPs can be taken as a clear indication of the contribution of the sector to food security and poverty alleviation. The use of finfish and other aquatic organisms as a feed source can be through direct utilization of whole or chopped raw fish in wet form, through fishmeal and fish oil in formulated feeds, and/or as live fish, although the latter is uncommon and the overall amounts used are relatively small. In the first two categories, the fish used are often termed “trash fish/low-value fish”. Although attempts have been made to define this term, all definitions have a certain degree of ambiguity and/or subjectivity. In this regional review, the amount of fish used as feed sources based on the above categories was estimated primarily from the production data, supported by assumptions on the inclusion levels of fishmeal in formulated feeds and observed feed conversion efficiencies for both formulated feeds and for stock fed trash fish/low-value fish directly. A scenario for the use of fish as feed was developed by starting from the levels of aquaculture production recorded in 2004 and assuming increases in production volumes of 10, 15 and 20 percent by 2010, respectively, for the three trajectories. In parallel, the pattern of wild fish use as feed was projected to change as fish and shrimp farmers increasingly replace farmmade feeds by incorporating trash fish/low-value fish with manufactured feeds that include fishmeal. Also, the fishmeal inclusion rates in manufactured feeds are falling slowly, and this has been incorporated into the projections. The regional review also deals with the production of fishmeal using trash fish/low-value fish in the Asia-Pacific region. Regional fishmeal production as a whole is relatively low when compared with that of major fishmeal-producing countries such as Chile, Iceland and Norway, amounting to approximately 1 million tonnes per year. However, there is a trend towards increasing the use of fish industry waste, such as from the tuna canning industry in Thailand. The fishmeal produced in the region is priced considerably lower than globally traded fishmeal, but its quality is poorer. Total fishmeal use in Asian aquaculture in 2004 was estimated as 2 388 million tonnes, the highest proportion of this being used for crustacean aquaculture (1 418 million tonnes). Based on growth predictions (to year 2010) in the sector and improvements to feed quality and management, it is expected that the quantity of fishmeal used in Asian aquaculture will be slightly less than at present. An estimated 240 000 tonnes of fish oil is used in Asian aquaculture, principally in shrimp feeds. Based on production estimates of commodities in 2004 that rely on trash fish/low-value fish as the main feed source, this regional review suggests that Asian aquaculture currently uses between 2 465 and 3 882 million tonnes, an amount that is predicted to decrease to between 1.890 and 2 795 million tonnes by 2010. The use of trash fish/low-value fish and fishmeal by the aquaculture sector has been repeatedly adjudicated as a non-sustainable practice, and globally the sector is seeking to reduce its dependence on fish as feed through improved feed management practices and development of better quality feeds and feed formulations using alternative ingredients. Over the next few years, decreases in the use of trash fish/low-value fish are also expected to be achieved through better conversion of raw materials into fishmeal and fish oil during the reduction processes. The “way forward” in addressing the issue of the use of fish as feed in aquaculture in the Asia-Pacific region includes the need for a concerted regional research thrust to reduce the use of fish as feed sources in aquaculture, as has been achieved in the animal husbandry sector. Secondly, there is a need to increase farmer awareness on the use of trash fish as feed. This is achievable, considering the similar progress that has been made by the region’s shrimp farming sector, which almost exclusively involves small-scale practitioners who are often clustered in a given locality. The analysis also suggests that the use of trash fish/low-value fish in aquaculture may be compatible with improving food security and alleviating poverty. In Asia, trash fish/low-value fish is mostly landed in areas where there are other suitable fish commodities for human consumption. To make the trash fish/low-value fish suitable and available for human consumption would involve some degree of value-adding and transportation costs, which are likely to increase the price to beyond the means of the consumer, particularly in remote rural areas. Under such a scenario, the direct or indirect use of this perishable resource as a feed source to produce a consumable commodity appears to make economic sense and appears to be the most logical use for overall human benefit. In this manner, trash fish/low-value fish contributes to food security by increasing income generation opportunities and hence contributes to poverty alleviation. Another factor that needs to be taken into account is the large numbers of artisanal fishers who harvest this raw material. The continued use of trash fish/low-value fish, therefore, allows these fishers to maintain their livelihoods1. Admittedly, this is an area that warrants more detailed investigation, from resource use, livelihoods and economic viewpoints.

This study investigated the beliefs and practices of 28 teachers of the deaf about their practices. The teachers were all working in oral settings either as visiting teachers or teachers in a mainstream school facility supporting groups of students with hearing loss. Teachers who used an Auditory Verbal approach largely adopted a positivist paradigm, whereas those using an Auditory Oral approach were more likely to adopt a constructivist paradigm. Those using a mixed approach (AV/AO) adopted a paradigm that was a mix of both positivist and constructivist. Results suggest that there is a strong relationship between the underlying beliefs of teachers and the model of practice that they adopt, and that professional experience, professional development and the inclusion movement exert an influence on those beliefs and practices.

This paper examines the complex connections between literacy practices, the use of information and communication technologies (ICTs) and disadvantage. It reports the findings of a year-long study which investigated the ways in which four families use ICTs to engage with formal and informal literacy learning in home and school settings. The research set out to explore what it is about computer-mediated literacy practices at home and at school in disadvantaged communities that make a difference in school success. The findings demonstrate that the 'socialisation' of the technology - its appropriation into existing family norms, values and lifestyles - varied from family to family. Having access to ICTs at home was not sufficient for the young people and their families to overcome the so-called 'digital divide'. Clearly, we are seeing shifts in the meaning of 'disadvantage' in a globalised world mediated by the use of new technologies. New definitions of disadvantage that take account not only of access to the new technologies but also include calibrated understandings of what constitutes the access are required. The article concludes that old inequalities have not disappeared, but are playing out in new ways in the context of the networked society.

This study examines associations between parental feeding restriction at baseline and child body mass index (BMI) z-score at 3-year follow-up. Parents of 204 5–6-year-old and 188 10–12-year-old children completed the Child Feeding Questionnaire at baseline (2002/3). In 2002/3 and 2005/6, children's BMI z-score was calculated from measured height and weight. Analyses were stratified by age-group. The association of follow-up zBMI and baseline feeding restriction score was explored using (i) linear regression with adjustment for baseline zBMI and (ii) with further adjustments for baseline maternal BMI, maternal education level and child sex. Baseline restriction was associated with follow-up zBMI at 3 years in 5–6-year-old children and was largely unchanged when adjusting for child sex, maternal BMI and education. Restriction was not associated with follow-up zBMI in 10–12-year-old children. This longitudinal study adds important depth to our understanding of associations between restrictive feeding and change in zBMI, suggesting that restriction of energy-dense foods and drinks may be protective of unhealthy weight gain in younger children but may have no effect among older children. These findings support a reconsideration of the notion that restriction is likely to result in increased child weight.

Background: Malnutrition and its associated complications are a considerable issue for surgical patients with upper gastrointestinal and colorectal cancer.The present study aimed to determine whether specific perioperative nutritional practices and protocols are associated with improved patient outcomes in this group.
Methods: Patients admitted for elective upper gastrointestinal or colorectal cancer surgery (n = 95) over a 19-month period underwent a medical history audit assessing weight changes, nutritional intake, biochemistry, post-operative complications and length of stay. A subset of patients (n = 25) underwent nutritional assessment by subjective global assessment prior to surgery in addition to assessment of post-operative medical outcomes, nutritional intake and timing of dietetic intervention.
Results: Mean (SD) length of stay for patients was 14.0 (12.2) days, with complication rates at 35%. Length of stay was significantly longer in patients who experienced significant preoperative weight loss compared to those who did not [17.0 (15.8) days versus 10.0 (6.8) days, respectively; P < 0.05]. Low albumin and post-operative weight loss were also predictive of increased length of stay. Of patients who underwent nutritional assessment, 32% were classified as mild–moderately malnourished and 16% severely malnourished. Malnourished patients were hospitalised twice as long as well-nourished patients [15.8 (12.8) days versus 7.6 (3.5) days; P < 0.05]. Time taken [6.9 (3.6) days] to achieve adequate nutrition post surgery was a factor in post-operative outcomes, with a positive correlation with length of stay (r = 0.493; P < 0.01), a negative correlation with post-operative weight change (r = —0.417; P < 0.05) and a greater risk of complications (52% versus 13%; P < 0.01).
Conclusions: Malnutrition is prevalent among surgical patients with gastrointestinal cancer. Poor nutritional status coupled with delayed and inadequate post-operative nutrition practices are associated with worse clinical outcomes.
