Inhibitors and facilitators for mobile payment adoption in Australia: a preliminary study

With the seamless diffusion and acceptance of mobile phones into people's everyday life as trusted communication devices, businesses have begun exploring their potential as payment devices. In this paper, we report on the findings from a pioneering study conducted in Australia, which explored inhibitors and facilitators in the adoption of mobile phones as payment devices.

Re-envisioning teacher education in the new media age: multiliteracies, multimodality and internet communication technologies

Multiliteracies pedagogy and research (New London Group, 1996) addresses the range of literacies needed by diverse students to effectively negotiate the increasing multimodality of texts, both inside and outside of schools. Yet, few university teachers understand how youth are able to express themselves, their experiences and lives, in new, empowering and perception-shifting ways as designers in the 21st century. Several theorists (Bruce, 2000; Lemke, 1998; Luke, 2000; Bolter, 1998; Glister, 1997) argue literacy education must be reconceptualised to recognize the importance of teaching and supporting multimedia literacy in a world where internet communication technologies (ICTs) incorporate all semiotic resources. Expression through multiple media and more recently hypermedia—is common to youth—but has often been demonized by historically logocentric approaches to teaching and assessment by privileging print, over all other forms of expression (Albright & Walsh, 2003; Lemke, 1998; McCloud, 1993). As digital media becomes more pervasive in a post-typographic world, tertiary education will need to engage with its representational resources for acquiring traditional school literacy and knowledge. This paper reports on initiatives in Multiliteracies instruction for both pre-service and in-service teachers to more adequately attend to the multisemiotic landscapes of students’ changing worlds in New Times (Hall, 1996).

Studio - learning and teaching environment for multimedia

This paper is a case study of the introduction of a studio environment for the teaching of multimedia practice. This change is in the context of multimedia being placed within an information technology degree program, where the conventions and traditions of computer science prevail. The studio based teaching was accepted and now new studios are being built at the university and a research project is proposed with the Queensland University of Technology to explore further teaching and learning issues using studio
teaching methods.

Design guidelines for children programming in school environment

This paper describes design guidelines of a programming environment for children, aiming to lower the barriers for children to learn programming. Our model called GBuilder has been developed on the basis of guidelines, with the express purpose of enabling and empowering the students to develop their own learning programs in survival literacy within enjoyable and fun environment.

Games geeks in context: developing the environment to engage creative expression

This paper explores the importance of purpose built combined technological and social collaborative environments in supporting the development of creativity in a cohort of students not generally associated with creative abilities. A supportive and nurturing environment provides these university students with a community where they can share knowledge and ideas, and subsequently engage in creative activities and behaviours. Such an environment directly impacts on the levels of engagement with which students� participate in their learning process. The authors draw on findings derived from a study of first year computer science students enrolled in a games design and development unit at an Australian university. This paper will focus on the ways in which the participants negotiate and regulate the exercise of power and control in the environment in order to enhance their own creative expression.

Designing contemporary e-supported professional development environments to enhance tertiary teaching and learning

National and organsational imperatives in Australian higher education are demanding systematic and cost-effective approaches to the professional development of staff in their teaching in order to enhance the quality of student learning. Many universities are geographically distributed, multi- campus, multi-city and multi-modal in nature, and highly dependent for their effective operation on information and communications technologies (ICT). Deakin University is one such university operating in Australian higher education. Consistent with the progressive principles and practices of the learning organisation, new approaches and environments are required to support the professional development of staff for enhanced teaching and learning in higher education. These environments now require substantial use of e-learning for both learning about teaching online and the development of teaching capacities in the world of the modern-day, technologically-supported physical classroom. This article outlines the imperatives to establish and operate cost-effective e-supported environments for professional development for excellence in teaching and learning. The key principles underlying these emergent environments are outlined, along with the major tools, resources and features of such environments. A contemporary online teaching case site is highlighted as indicative of new approaches to supporting professional development of staff for excellence in online teaching and learning.

Developing and rewarding advanced teaching expertise in higher education - a different approach

The Australian university sector is undergoing a major change, with a significant increase in the emphasis on quality teaching and learning. This change is being driven by the national government. The paper asks if the correct response to this change of emphasis should be a change in the attitude to the appropriate mix of research and teaching skills within an institution, and within individual staff of the institution. The same question could be asked of how to better develop teaching expertise in many higher education sectors globally. It is proposed that to create excellent teaching and learning within an institution may better be achieved by allowing staff to become experts in a narrow field of teaching rather than
generalists across the basics of teaching. The creation of a Community of Experts in teaching parallels the process of creating a Community of Experts in Research and can bring similar benefits in the teaching area to what it does in the research area.

Appropriate body-mass index for Asian populations and its implications for policy and intervention strategies

A WHO expert consultation addressed the debate about interpretation of recommended body-mass index (BMI) cut-off points for determining overweight and obesity in Asian populations, and considered whether population-specific cut-off points for BMI are necessary. They reviewed scientific evidence that suggests that Asian populations have different associations between BMI, percentage of body fat, and health risks than do European populations. The consultation concluded that the proportion of Asian people with a high risk of type 2 diabetes and cardiovascular disease is substantial at BMIs lower than the existing WHO cut-off point for overweight (25 kg/m2). However, available data do not necessarily indicate a clear BMI cut-off point for all Asians for overweight or obesity. The cut-off point for observed risk varies from 22kg/m2 to 25kg/m2 in different Asian populations; for high risk it varies from 26kg/m2 to 31kg/m2. No attempt was made, therefore, to redefine cut-off points for each population separately. The consultation also agreed that the WHO BMI cut-off points should be retained as international classifications. The consultation identified further potential public health action points (23·0, 27·5, 32·5, and 37·5 kg/m2) along the continuum of BMI, and proposed methods by which countries could make decisions about the definitions of increased risk for their population.

Hybridity, globalisation and literacy education in the context of New York City

Although multiliteracies have been well theorised in recent years, few studies have researched the practical aspects of developing a curriculum of multiliteracies. This article examines multiliteracies as a crossdisciplinary curriculum practice, drawing on data from a 3-year study in an urban middle school. The data show possibilities for students to engage in critique and to move toward designing multimodal texts. Using Bourdieusian concepts of social capital and academic field, we explore the struggles around learning to inhabit certain school discourses.

Body size, body composition, and fat distribution: a comparison of young New Zealand men of European, Pacific Island, and Asian Indian ethnicities

Aims To investigate body size and body fat relationships and fat distribution in young healthy men drawn from New Zealand European, Pacific Island, and Asian Indian populations.
Method A total of 114 healthy men (64 European, 31 Pacific Island, 19 Asian Indian) aged 17–30 years underwent measurements of height, weight, and body composition by total body dual-energy X-ray absorptiometry (DXA). Body mass index (BMI) was then calculated. Percent body fat (%BF), fat-free mass, bone mineral content, bone mineral density, abdominal fat, thigh fat, and appendicular skeletal muscle mass (ASMM) were obtained from the DXA scans.
Results For the same BMI, %BF for Pacific Island men was 4% points lower and for Asian Indian men was 7–8% points higher compared to Europeans. Compared to European men for the same %BF, BMI was 2–3 units higher for Pacific Island, and 3–6 units lower for Asian Indian. The ratio of abdominal fat to thigh fat, adjusted for height, weight, and %BF, was significantly higher for Asian Indian men than European (p=0.022) and Pacific Island (p=0.002) men. ASMM, adjusted for height and weight, was highest in Pacific Island and lowest in Asian Indian men.
Conclusions The relationship between %BF and BMI is different for European, Pacific Island, and Asian Indian men which may, at least in part, be due to differences in muscularity. Asian Indians have more abdominal fat deposition than their European and Pacific Island counterparts. Use of universal BMI cut-off points are not appropriate for comparison of obesity prevalence between these ethnic groups.

Facts on fats

Cardiovascular disease and age-related macular degeneration (AMD) may share common risk factors in their causal pathways. Decades of research from the cardiovascular sciences on fats have led investigators to focus on specific types of fats rather than total fat as a whole. They have established that saturated and trans-unsaturated fats (trans fats) are damaging to cardiovascular health while polyunsaturated fats, particularly the marine omega 3 fatty acids appear protective. This has led to a number of studies investigating the associations of fat and AMD. Though the causal relationship between fats and AMD remain unproven, some studies suggest that an association may be present. To be able to understand and interpret the study results and their implications, an understanding of the fats in the diet is important. This review aims to give an overview of fatty acids, particularly the trans-unsaturated fatty acids, and the relevant food groups.

The subcellular fractionation properties and function of insulin receptor substrate-1 (IRS-1) are independent of cytoskeletal integrity

Efficient insulin action requires spatial and temporal coordination of signaling cascades. The prototypical insulin receptor substrate, IRS-1 plays a central role in insulin signaling. By subcellular fractionation IRS-1 is enriched in a particulate fraction, termed the high speed pellet (HSP), and its redistribution from this fraction is associated with signal attenuation and insulin resistance. Anecdotal evidence suggests the cytoskeleton may underpin the localization of IRS-1 to the HSP. In the present study we have taken a systematic approach to examine whether the cytoskeleton contributes to the subcellular fractionation properties and function of IRS-1. By standard microscopy or immunoprecipitation we were unable to detect evidence to support a specific interaction between IRS-1 and the major cytoskeletal components actin (microfilaments), vimentin (intermediate filaments), and tubulin (microtubules) in 3T3-L1 adipocytes or in CHO.IR.IRS-1 cells. Pharmacological disruption of microfilaments and microtubules, individually or in combination, was without effect on the subcellular distribution of IRS-1 or insulin-stimulated tyrosine phosphorylation in either cell type. Phosphorylation of Akt was modestly reduced (20–35%) in 3T3-L1 adipocytes but not in CHO.IR.IRS-1 cells. In cells lacking intermediate filaments (Vim^−/−) IRS-1 expression, distribution and insulin-stimulated phosphorylation appeared normal. Even after depolymerisation of microfilaments and microtubules, insulin-stimulated phosphorylation of IRS-1 and Akt were maintained in Vim^−/− cells. Taken together these data indicate that the characteristic subcellular fractionation properties and function of IRS-1 are unlikely to be mediated by cytoskeletal networks and that proximal insulin signaling does not require an intact cytoskeleton.
