Changing technologies / renewing pedagogies : implications for university teaching and learning

This chapter describes a project that researched the use of Web Enhanced Learning (WEL) with postgraduate students from rural and remote communities who were studying through two Australian universities. We examine, in detail, the experiences of a university teacher using WEL in an off-campus course for the first time. As with many academic teachers, she was willing to use new technologies and integrate these into her teaching but required time, technical support and professional development to achieve this. Using a design-based rnethodological approach, the experiences and frustrations in introducing WEL are described from the teacher's perspective trough her progressive reflections at stages throughout the course. The findings and their implications for university policy and leadership are detailed with conclusions about how teachers and students are best supported in their engagernent with WEL.

The role of memory in establishing and destabilising choreographic practice

This practice-based research examines the role of body memory, seen as a multiple and complex process in the development of a choreographic aesthetic, specifically in relationship to the creation of choreography. The thesis explores the idea that a dancer's body memory is not necessarily stable, but rather a constantly altered system.

Application of sequential nonparametric confidence bands in finance

In a nonparametric setting, the functional form of the relationship between the response variable and the associated predictor variables is assumed to be unknown when data is fitted to the model. Non-parametric regression models can be used for the same types of applications such as estimation, prediction, calibration, and optimization that traditional regression models are used for. The main aim of nonparametric regression is to highlight an important structure in the data without any assumptions about the shape of an underlying regression function. Hence the nonparametric approach allows the data to speak for itself. Applications of sequential procedures to a nonparametric regression model at a given point are considered.

The primary goal of sequential analysis is to achieve a given accuracy by using the smallest possible sample sizes. These sequential procedures allow an experimenter to make decisions based on the smallest number of observations without compromising accuracy. In the nonparametric regression model with a random design based on independent and identically distributed pairs of observations (X ,Y ), where the regression function m(x) is given bym(x) = E(Y X = x), estimation of the Nadaraya-Watson kernel estimator (m (x)) NW and local linear kernel estimator (m (x)) LL for the curve m(x) is considered. In order to obtain asymptotic confidence intervals form(x), two stage sequential procedure is used under which some asymptotic properties of Nadaraya-Watson and local linear estimators have been obtained.

The proposed methodology is first tested with the help of simulated data from linear and nonlinear functions. Encouraged by the preliminary findings from simulation results, the proposed method is applied to estimate the nonparametric regression curve of CAPM.

Unspeakable terrain : visualising ontological terror in performance

This paper presented at the 2010 ADSA Conference held at the Australian National University draws upon my practice based research submitted for a Master of Animateuring (Cross Modal Performance) at the faculty of the Victorian College of the Arts- Melbourne University. Aviary which premiered at the Living Museum of the West in 2006 (a visual space-specific performance during which only one word was uttered) was used as an exemplar of my practice revealing how ontological terror can only be artistically represented through carefully chosen veils, two of which can be made explicit through an analysis of the aesthetic conventions of the liminal uncanny and the traumatic sublime.

Singular influence : mapping the ascent of Daisy M. Bates in popular understanding and Indigenous policy

Daisy M. Bates’s influence on Indigenous affairs has often been attributed to her once romantic legend as ‘the saviour of the Aborigines’, obscuring the impact of the powerful news media position that she commanded for decades. The ideas advanced by the news media through its reports both by and about Bates exerted a strong influence on public understanding and official policies that were devastating for Indigenous Australians and have had lasting impacts. This paper draws on Bourdieu’s tradition of field-based research to propose that Bates’s ‘singular influence’ was formed through the accumulation of ‘symbolic capital’ within and across the fields of journalism, government, Indigenous societies, and anthropology, and that it operated to reinforce and legitimate the media’s representations of Indigenous people and issues as well as government policies.

Problems of psychological and sociocultural adaptation among Russian speaking immigrants in New Zealand

The problems immigrants experience during the process of their psychological and sociocultural adaptation to the host culture have far-reaching effects in terms of mental health, employment and lost benefits for the whole society. General models of the acculturation process (Ward 1996) and acculturation strategies (Berry 2001) provide a basis for the analysis of those problems. The current study employed a qualitative, case-oriented design, based on the grounded theory method to analyse interviews with six Russian-speaking immigrants in New Zealand. The purpose of the study was to investigate, from a psychological perspective, the problems in adaptation as a result of migration and resettlement, and the factors that influence this process. Two distinct patterns were revealed, linked to acculturation strategies of integration and separation. All the participants experienced high levels of psychological distress in the initial stage of their resettlement, but those who later chose the integration strategy of acculturation were more successful and satisfied with their adaptation than those who chose the strategy of separation. Factors contributing to the process of adaptation were migration motivation, proportion of perceived gains and losses, and cultural identity. This study has implications for social policies in the areas of employment, education and mental health.

Assessing free-living physical activity using accelerometry : practical issues for researchers and practitioners

Physical activity is an integral component of a healthy lifestyle, with relationships documented between physical activity, chronic diseases, and disease risk factors. There is increasing concern that many people are not sufficiently active to benefit their health. Consequently, there is a need to determine the prevalence of physical activity engagement, identify active and inactive segments of the population, and evaluate the effectiveness of interventions. The aim of the present study was to identify and explain a number of methodological and decision-making processes associated with accelerometry, which is the most commonly used objective measure of physical activity in child and adult research.

Specifically, this review addresses:
(a) pre-data collection decisions,
(b) data collection procedures,
(c) processing of accelerometer data, and
(d) outcome variables in relation to the research questions posed.

An appraisal of the literature is provided to help researchers and practitioners begin field-based research, with recommendations offered for best practice. In addition, issues that require further investigation are identified and discussed to inform researchers and practitioners of the surrounding debates.

Overall, the review is intended as a starting point for field-based physical activity research using accelerometers and as an introduction to key issues that should be considered and are likely to be encountered at this time.

Football's culture of intoxication : implications for health promotion

Objectives: The objective of this is article is to examine some of the strategies and interventions designed to encourage responsible alcohol consumption within Australian Rules football clubs.
Design: Qualitative research was undertaken with fans of four fans of football teams who compete in the South Australian National Football League (SANFL). In total, 93 interviews were conducted with male (80) and female (13) fans across these clubs. Interview data were thematically analysed with the assistance of the NVIVO software package. To elicit additional insight about the social meanings of drinking, researchers visited football games and a range of social functions.
Results: Analysis of the qualitative data suggests that formal interventions implemented by football clubs often prove ineffectual in encouraging responsible alcohol consumption, with more effective strategies aimed at dissuading heavy drinking being operationalized at an informal level by drinkers themselves through a number of ‘everyday’ or ‘lay’ strategies. Such strategies correspond to the broad analytical categories of ‘keeping safe’, ‘minimising damage’ and ‘taking charge’.
Conclusion: This focus on the role of lay strategies in informing health behaviours makes an important contribution to how we understand health promotion initiatives in relation to harmful drinking in sport and other contexts.

To occupy: panoramic interiors of concrete fortifications

This series of images began with an investigation into the notion of inhabitation as a negotiated process. Through practice-based research, the series has become focused on the interiors of concrete fortifications along the east and south coasts of Australia. I am interested in the ‘shudder’ one experiences when encountering a room that has resonance; that has duration; where past, present and future collapse.

Enhancing business intelligence traceability through an integrated metadata framework

The Business Intelligence (BI) system provides users with multi-dimensional information (so-called BI product) to support their decision-making. However, very often business users still could not fully understand the BI product, nor have a clear picture of the entire information manufacturing chain of the BI product. In response to this situation, this paper presents an integrated metadata framework (“BIP-Map”) to facilitate the traceability and accountability of a BI product following the design science research approach. Specifically, the salient modelling and management techniques from the business process modelling notation (BPMN), the information product map (IP-Map), and the metadata management are adapted to construct a three-layered integrated metadata framework enabling the business users to make timely and informed decisions. A BIP-Map informed prototype system has been developed in collaboration with online job recruitment firms. The authors conducted in-depth interviews with seven key BI stakeholders of the recruitment firms to evaluate the usefulness of the BIP-Map. It is envisaged that the metadata framework allows the technical personnel to understand the business processes that relate to certain information provided in the BI reports. Business users will also be able to gain insights into the logic behind any BI report.

Optimising the life cycle energy performance of residential buildings

A holistic approach to low-energy building design is essential to ensure that any efficiency improvement strategies provide a net energy benefit over the life of the building. Previous work by the authors has established a model for informing low-energy building design based on a comparison of the life cycle energy demand associated with a broad range of building assemblies. This model ranks assemblies based on their combined initial and recurrent embodied energy and operational energy demand. The current study applies this model to an actual residential building in order to demonstrate the application of the model for optimising a building’s life cycle energy performance. The aim of this study was to demonstrate how the availability of comparable energy performance information at the building design stage can be used to better optimise a building’s energy performance. The life cycle energy demand of the case study building, located in the temperate climate of Melbourne, Australia, was quantified using a comprehensive embodied energy assessment technique and TRNSYS thermal energy simulation software. The building was then modelled with variations to its external assemblies in an attempt to optimise its life cycle energy performance. The alternative assemblies chosen were those shown through the author’s previous modelling to result in the lowest life cycle energy demand for each building element. The best performing assemblies for each of the main external building elements were then combined into a best-case scenario to quantify the potential life cycle energy savings possible compared to the original building. The study showed that significant life cycle energy savings are possible through the modelling of individual building elements for the case study building. While these findings relate to a very specific case, this study demonstrates the application of a model for optimising building life cycle energy performance that may be applied more broadly during early-stage building design to optimise life cycle energy performance.

This exhibition included 22 paintings. They were all expressionist, surreal paintings based on my experience of being a new Australian but reflecting at the same time on my other ‘home places’. These represent arts practice based research exploring identity and place.

Stone soup installation

This installation work sets out a number of proposals for future collaborations with the Southwest Victoria regions communities. Through a series of drawings/ diagram that focus on particular aspects of the region: stone walls, eel weirs. The concept for the work is taken from the folktale of travelers who come to a village asking for food and when denied, they make a magical stone soup which only need a few garnishes. in the end the traveler have enough soup for the entire village. this stands as a allegory of the way artist engage with community and induce cooperative activities a through the trickery of art practices by which all can partake and produce common, mutually beneficial experience.

Building awareness of mathematical modelling at teacher education: a case study in Indonesia

A growing interest to teach mathematics closely connected to its use in daily life has taken place in Indonesia for over a decade (Sembiring, Hadi, and Dolk 2008). This chapter  reports an exploratory case study of  the building of an awareness of mathematical modelling in teacher education in Indonesia. A modelling task, re-designing a parking lot (Ang 2009), was assigned to groups of pre-service secondary mathematics teachers. All groups undertook the stages of collecting data on a parking lot, identifying limitations in the current design of the parking lot, and proposing a new design based on their observations and analyses. The nature of the mathematical models elicited by pre-service teachers during various stages of completing the modelling task will be examined. Implications of this study suggest the need to encourage pre-service teachers to state the assumptions and real-world considerations and link them to the mathematical model in order to validate their models.

The needs, concerns and characteristics of younger Australian adults with Type 2 diabetes

Aims : The mean age of onset of Type 2 diabetes mellitus is decreasing in Australia and internationally. We conducted an internet-based survey to improve our understanding of the emotional well-being and unmet needs of younger adults with Type 2 diabetes, and to inform service provision for this group.

Methods : A random sample of National Diabetes Services Scheme registrants (n = 1,417) with Type 2 diabetes, aged 18–39 years, living in the Australian state of Victoria received an invitation to complete the online survey. The study was also advertised state-wide. The survey included validated scales (PAID-5: diabetes-related distress; WHO-5: general emotional well-being) and study-specific items. A total of 149 eligible respondents participated.

Results : Almost two-thirds (63%) of respondents reported severe-diabetes related distress; more than a quarter (27%) had impaired general emotional well-being. Most (82%) were overweight or obese (BMI ≥ 25); most (77%) had at least one other co-morbidity. Lack of motivation, feeling burned out, and being time-poor were identified as top barriers to self-management. More than half (59%) of respondents had not participated in structured diabetes education. Respondents perceived that younger adults with Type 2 diabetes had different health-care needs than their older counterparts (68%), and that most Type 2 diabetes information/services were aimed at older adults (62%). Of a range of potential new services, respondents indicated greatest interest in an online forum specifically for younger adults with Type 2 diabetes.

Conclusions : Younger adults with Type 2 diabetes have impaired emotional well-being and physical health. Population-based research is needed to confirm the current findings, to further inform service delivery and optimise outcomes for this group.
