Selenium content of Australian foods: a review of literature values

The aim of this study was to review the published literature values for the selenium content of Australian foods. A secondary aim was to compare the results for Australian foods with food composition data from international sources to investigate the extent of geographical variation. Published food composition data sources for the selenium content in Australian foods were identified and assessed for data quality using established criteria. The selenium content is available for 148 individual food items. The highest values found are for fish (12.0–63.2 μg/100 g), meats (4.75–37.9 μg/100 g) and eggs (9.00–41.4 μg/100 g), followed by cereals (1.00–20.3 μg/100 g). Moderate levels are seen in dairy products (2.00–7.89 μg/100 g) while most fruits and vegetables have low levels (trace—3.27 μg/100 g). High selenium foods show the greatest level of geographical variation, with foods from the United States generally having higher selenium levels than Australian foods and foods from the United Kingdom and New Zealand having lower levels. This is the first attempt to review the available literature for selenium composition of Australian foods. These data serve as an interim measure for the assessment of selenium intake for use in epidemiological studies of diet–disease relationships.

A quality indicator of Australian e-business

Organisations spend large sums of money to ensure that their electronic shopfront is as attractive, appealing and efficient as any in the real world. But what about dealing with customers? If someone has a query in the real world they would perhaps approach a sales person or telephone the organisation to obtain a response. The electronic equivalent is e-mail. Do organisations pay sufficient attention to this aspect of their electronic shopfront? The study reported here was undertaken to determine the use of e-mail within Australian organisations and, more importantly, organisations' responsiveness to e-mail
queries.

Information systems development contracts : An exploratory study of Australian legal pratitioners' and information systems professionals' perceptions

IS professionals are primarily concerned with the development of a project to meet the goals of a client. Unfortunately, IS professional do not always pay close attention to the contract or to its management and are often unaware of the legal implications of the contracts to which they are assenting. Legal advice can be sought during pre-contractual processes to help ensure that the contract meets the expectations of all the parties. If the project does not meet stakeholder’s expectations, thus causing a contract to come into dispute, lawyers may be called in to review the contract and to seek a settlement. This paper reports an exploratory study of the differences in perceptions of IS development contracts that exist between IS professionals and legal practitioners.

Online banking vs. bricks & mortar - or a hybrid model? A preliminary investigation of Australian and Indian banks

Deregulation, innovations in mobile and wireless technologies and media convergence, together with the rapid diffusion of the Internet, have opened up strategic business opportunities in the financial sector. With deregulation removing entry barriers, an increasing number of online banks are threatening the market share of ‘bricks and mortar’ banks. To survive this competition, and to leverage the new opportunities of online and mobile banking facilitated by the Internet, many banks have adapted a hybrid, ‘clicks and mortar’ model, to increase their profitability while reducing transaction costs. In this paper, we report the results of a preliminary analysis based on a few major banks in Australia and India, two diverse economies, to reveal some interesting insights.

Do dot coms add value : a preliminary study of the market capitalisation of Australian and Indian telecoms and banking sectors

E-Business is increasingly reshaping the way businesses operate across the globe. Globally, businesses in the banking and telecoms sectors have been re-engineering their value chains by adopting e-Business presence by means of dot com launches. The second half of the 1990s, however, saw both the rise and subsequent collapse of dot com entities as a major focus of investment interest, with consequent speculation over the viability of this corporate vehicle. The perceived increase in market capitalisation by means of these ventures during the boom period is now not so certain. In this paper, we report the results of a preliminary study which investigated the impact of dot com launches on market capitalisation within the banking and telecoms sectors of Australia and India.

Characteristics of Australian B2B imarketplaces

Existing research on B2B iMarketplaces (and intermediaries operating them) focuses primarily on viewing US iMarketplace web sites or conducting case studies. This paper extends this work by presenting survey findings of the total identifiable population of Australian B2B iMarketplace intermediaries to describe the iMarketplace characteristics and to determine if the findings provide more generalisable support for the literature.

Validation of the use of Australian input-output data for building embodied energy simulation

Traditional!y, the simulation of buildings has focused 011 operational energy consumption in an attempt to determine the potential for energy savings. Whilst operational energy of Australian buildings accounts for around 20% of total energy consumption nationally, embodied energy represents 20 to 50 times the annual operational energy of 1110st Australian buildings. Lower values have been shown through a number of studies that have analysed the embodied energy of buildings and their products, however these have now shown to be incomplete in system boundary. Many of these studies have used traditional embodied energy analysis methods, such as process analysis and input-output analysis, Hybrid embodied energy analysis methods have been developed, but these need to be compared and validated. This paper reports on preliminary work on this topic. The findings so far suggest that current best-practice methods are sufficiently accurate for most typical applications, but this is heavily dependant upon data quality and availability.

The orientation of Australian coursework-focussed marketing masters degree

Using content analysis, this paper examines the orientation of Australian coursework masters degrees in marketing by analysing data collected from 38 university websites on the entry requirements, degree structure and research opportunities of the programs. The findings indicate that there appears to be an attempt to offer programs aiming at a range of “outcomes”, i.e. training for PhD, advanced studies in marketing, or accreditation for those in the industry. The diverse orientation of the degrees offered means that Australian institutions are potentially facing a challenge, targeting programs at different market segments.

Characteristics and underpricing of Australian mining and energy IPOs from 1994 to 2001

This paper follows How (2000) who examined 130 Australian mining and energy initial public offerings (IPOs) from 1979 to 1990 to report an average 107.18 % underpricing return by those IPOs. This study updates that report by investigating 127 Australian mining and energy IPOs from 1994 to 2001 to find a substantially lower 17.93 % average first day return. These updated findings have implications for both new companies seeking to float and also for the subscribers wishing to invest in these new listings.

Solving problems collaboratively online : experiences of Australian and Chinese heritage university students

The research reported in this paper is part of a larger project designed to compare the online collaborative learning behaviours of Chinese Heritage Culture (CHC) university students, for whom a Chinese dialect is a first language, with Australian university students of European descent, and for whom English is a first language. The collaborative learning discussion focussed on in the research involved fellow students, rather than tutorial staff, facilitating those discussions.

The first component of the research was quantitative, comprising a questionnaire on readiness for online learning, and a quantitative analysis of student postings to a student-led collaborative problem solving task conducted online. The first component of the research (reported in Smith et at, 2005) showed no differences between the two groups in their willingness to self-manage their own learning, but did show that the CHC students were significantly less comfortable than the Australian students with online learning. Student postings to the online discussions were classified into organisational postings, social postings, and intellectual. There were substantial differences between the two groups in their patterns of online postings among those classifications, as well as differences in the length of postings made.

This paper will explore these findings in more detail through qualitative data generated through interviews with a subset of students from each group. Interview data provided further insight into the lesser comfort with e-learning among CHC students. Students from both groups felt there were inefficiencies in the online discussion, but CHC students also felt rather marginalised by the process. Australian students were more likely to evaluate the experience in terms of its capacity to achieve required learning outcomes in a time efficient way, while CHC students expressed more concern about how the process had impacted upon them personally. The interview data also indicated that a tutor sensitive to cultural difference is important for comfort among the CHC students in particular, since there is need for encouragement to those students to make reflective inputs to the discussion.
