An editor's view of telemedicine

Should an editor hold a view about telemedicine, or should an editor be entirely disinterested? The editorial role has been defined by the International Committee of Medical journal Editors and a long list of editorial responsibilities has been set out by the World Association of Medical Editors. This represents something of a counsel of perfection, although clearly an editor should not have a personal view, in the sense of promoting telemedicine or dismissing it. Since telemedicine editors are almost bound to be active in research, they should take particular care with manuscripts involving their own work, for example standing aside from the editorial process and delegating editorial decisions to other members of the editorial staff. At the beginning of the 1990s, there were few publications about telemedicine in the peer-reviewed literature. The subsequent years have seen a rapid growth in numbers of articles and the emergence of two specialist journals. These are all healthy signs. However, there have been remarkably few studies of telemedicine's cost-effectiveness, which must represent a sign of its immaturity. On balance, the evidence seems to indicate that telemedicine research is in a healthy state.

Paediatric palliative home care with Internet-based video-phones: lessons learnt

We have designed and tested an Internet-based video-phone suitable for use in the homes of families in need of paediatric palliative care services. The equipment uses an ordinary telephone line and includes a PC, Web camera and modem housed in a custom-made box. In initial field testing, six clinical consultations were conducted in a one-month trial of the videophone with a family in receipt of palliative care services who were living in the outer suburbs of Brisbane. Problems with variability in call quality-namely audio and video freezing, and audio break-up-prompted further laboratory testing. We completed a programme of over 250 test calls. Fixing modem connection parameters to use the V.34 modulation protocol at a set bandwidth of 24 kbit/s improved connection stability and the reliability of the video-phone. In subsequent field testing 47 of 50 calls (94%) connected without problems. The freezes that did occur were brief (with greatly reduced packet loss) and had little effect on the ability to communicate, unlike the problems arising in the home testing. The low-bandwidth Internet-based video-phone we have developed provides a feasible means of doing telemedicine in the home.

Automatic message handling for a national counselling service

An automatic email handling system (AutoRouter) was introduced at a national counselling service in Australia. In 2003, counsellors responded to a total of 7421 email messages. Over nine days in early May 2004 the administrator responsible for the management of the manual email counselling service recorded the time spent on managing email messages. The AutoRouter was then introduced. Since the implementation of the AutoRouter the administrator's management role has become redundant, an average of 12 h 5 min per week of staff time has been saved. There have been further savings in supervisor time. Counsellors were taking an average of 6.2 days to respond to email messages (n=4307), with an average delay of 1.2 days from the time counsellors wrote the email to when the email was sent. Thus the response was sent on average 7.4 days after receipt of the original client email message. A significant decrease in response time has been noted since implementation of the AutoRouter, with client responses now taking an average of 5.4 days, a decrease of 2.0 days. Automatic message handling appears to be a promising method of managing the administration of a steadily increasing email counselling service.

A comparison of attitudes among purchasers of imported fruit in Guangzhou and Urumqi, China

Research on Chinese consumer behavior is dominated by studies of Chinese consumers as a whole, or studies of consumers in a single city or region. Comparative studies that take into account the cultural, economic and demographic differences between contrasting markets within China are poorly represented in the literature. The widening economic gap between rapidly developing coastal cities and less developed cities in more remote regions provides an opportunity for comparative consumer studies. In this research we compared the responses of buyers of imported fruit in two very different cites, Guangzhou (highly developed) and Urumqi (relatively undeveloped). Results revealed that buyers' beliefs and their evaluation of those beliefs towards the attributes of imported fruit were distinctly different. Factors such as the city's background, consumers' education level and the intended uses explained most of these differences. Results will help to broaden our understanding of Chinese consumer behavior and provide valuable information when formulating marketing strategies. (C) 2003 Elsevier Ltd. All rights reserved.

Developing and evaluating authentic integration between research and coursework in professional doctorate programs

Integration has always been a prominent issue debated in the burgeoning literature on professional doctorate programs. This focus on integration, however, has largely involved the integration between theoretical and practical understandings of various professions. Exploring the integration between research and coursework components of professional doctorate programs has received less attention. This article explores the character of the integration between coursework and research in several professional doctorate programs at a number of Australian research-intensive universities and universities of technology. Using a content analysis methodology, this research charted the various models for sequencing research and coursework and established whether integration was an explicit or implicit goal of the espoused curriculum. It also sought to explore whether there were differences in the levels of integration in professional doctorate programs across different types of universities or patterns of variation across disciplines.

Impact of social group processes and functional diversity on communication in networked organizations

This study examines the role of social group processes in perceptions of effective communication in Australian Cooperative Research Centres (CRCs). Communication professionals in 25 CRCs discussed the barriers and opportunities for communication in their diverse networked organizations. Thematic analysis of the transcripts highlighted the contribution of social group processes to both barriers and opportunities. Communication challenges implicated the social identity of organizational members, many of which were associated with distinct structural aspects of these organizations. Opportunities for communication frequently involved features that implicated social identity, including taking advantage of existing organizational or industry identities, preventing conflicting identities from becoming salient, and promoting a collective CRC identity.

The other side of the coin: safety of complementary and alternative medicine

Most consumers consider complementary and alternative medicine (CAM) products inherently safe. The growing simultaneous use of CAM products and pharmaceutical drugs by Australian consumers increases the risk of CAM-drug interactions. The Therapeutic Goods Administration (TGA) has a two-tier, risk-based regulatory system for therapeutic goods - CAM products are regulated as low risk products and are assessed for quality and safety; and sponsors of products must hold the evidence for any claim of efficacy made about them. Adverse reactions to CAM products can be classified as intrinsic (innate to the product), or extrinsic (where the risk is not related to the product itself, but results from the failure of good manufacturing practice). Adverse reactions to CAM practices can be classified as risks of commission (which includes removal of medical therapy) and risks of omission (which includes failure to refer when appropriate). While few systematic studies of adverse events with CAM exist, and under-reporting is likely, most CAM products and practices do not appear to present a high risk; their safety needs to be put into the perspective of wider safety issues. A priority for research is to rigorously define the risks associated with both CAM products and practices so that their potential impact on public health can be assessed.

PVT behaviour of fluids with potential models optimised for phase equilibria

NPT and NVT Monte Carlo simulations are applied to models for methane and water to predict the PVT behaviour of these fluids over a wide range of temperatures and pressures. The potential models examined in this paper have previously been presented in the literature with their specific parameters optimised to fit phase coexistence data. The exponential-6 potential for methane gives generally good prediction of PVT behaviour over the full range of temperature and pressures studied with the only significant deviation from experimental data seen at high temperatures and pressures. The NSPCE water model shows very poor prediction of PVT behaviour, particularly at dense conditions. To improve this. the charge separation in the NSPCE model is varied with density. Improvements for vapour and liquid phase PVT predictions are achieved with this variation. No improvement was found in the prediction of the oxygen-oxygen radial distribution by varying charge separation under dense phase conditions. (C) 2004 Elsevier B.V. All rights reserved.
