Pbtrust: A Priority-Based Trust Model For Service Selection In General Service-Oriented Environments, Xing Su, Minjie Zhang, Yi Mu, Kwang Mong Sim

Associate Professor Minjie Zhang

How to choose the best service provider (agent), which a service consumer can trust in terms of the quality and success rate of the service in an open and dynamic environment, is a challenging problem in many service-oriented applications such as Internet-based grid systems, e-trading systems, as well as service-oriented computing systems. This paper presents a Priority-Based Trust (PBTrust) model for service selection in general service-oriented environments. The PBTrust is robust and novel from several perspectives. (1) The reputation of a service provider is derived from referees who are third parties and had interactions with the provider in a rich …

A Regression-Based Approach For Improving The Association Rule Mining Through Predicting The Number Of Rules On General Datasets, Dien Tuan Le, Fenghui Ren, Minjie Zhang

Dr Fenghui Ren

Association rule mining is one of the useful techniques in data mining and knowledge discovery that extracts interesting relationships between items in datasets. Generally, the number of association rules in a particular dataset mainly depends on the measures of support and confidence To choose the number of useful rules, normally, the measures of support and confidence need to be tried many times. In some cases, the measures of support and confidence are chosen by experience. Thus, it is a time consuming to find the optimal measure of supportand confidence for the process of association rule mining in large datasets. This …

Voltage Unbalance Emission Limits For Installations: General Guidelines And System Specific Considerations, Robert Koch, Alexander Baitch, Sarath Perera, Prabodha Paranavithana

Associate Professor Sarath Perera

Guidelines for developing voltage unbalance emission limits for installations connected to EHV, HV, and MV power systems have recently been published as a technical report by the International Electrotechnical Commission (IEC). These guidelines, based on the work of Joint Working Group CIGRE/CIRED C4.103, are intended to provide a common basis for the development of similar guidelines or standards in specific countries. This paper reviews these international guidelines and the background to the development of specific recommendations made in the technical report. It also considers elements of these guidelines that may relate to specific network considerations, and therefore may be of …

Benefits Derived From Ict Adoption In Regional Medical Practices: Perceptual Differences Between Male And Female General Practitioners, Robert Macgregor, Peter Hyland, Charles Harvie, Boon-Chye Lee

Associate Professor Peter Hyland

Information and communications technologies (ICTs) are being used more and more by general practitioners (GPs) in their day-to-day activities. While a number of studies have shown that ICT adoption and use can provide real benefits to medical practices, there have been few studies to determine whether the perception of those benefits is uniform across the sector. This study examines whether differences in the perception of benefits exist between male and female GPs. The results suggest that the groupings and priorities of benefits arising from ICT use differ substantially between male and female GPs. Results also show, amongst other things, that …

Do Organisational Characteristics Explain The Differences Between Drivers Of Ict Adoption In Rural And Urban General Practices In Australia, Robert C. Macgregor, Peter N. Hyland, Charles Harvie

Associate Professor Peter Hyland

A number of studies have compared general medical practices in rural locations with those in urban locations. Some of these studies have concentrated on the reasons why a GP might choose to work in a rural or urban setting. Others have examined the type of work required to be undertaken by medical professionals. Increasing use of information and communications technology (ICT) in medical practices has led to some studies examining their use in rural as well as urban settings. However, little if any research has examined whether ICT adoption drivers differ between rural and urban GPs based on their organisational …

Benefits Of Ict Adoption And Use In Regional General Medical Practices: A Pilot Study, Robert Macgregor, Peter Hyland, Charles Harvie, Boon-Chye Lee, Andrew Dalley, Sangeetha Ramu

Associate Professor Peter Hyland

This paper presents a pilot study of benefits derived from information and communications technology (ICT) adoption and use in medical practices in regional Australia. The study involved 122 regional medical practitioners. The results show that like the more general small businesssector, the perception of certain benefits is associated with the size of the practice (in terms of employee levels) and/ or the gender of the respondent practitioner.

Performance Auditing: The Jurisdiction Of The Australian Auditor General - De Jure Or De Facto? A Comment, John Glynn

John J Glynn

As Parker and Guthrie (1991) state, the question of the Australian Auditor- General’s performance audit mandate has become an issue of much debate over the last two decades.

The initial development of performance auditing by the Australian Audit Office (AAO) can be traced back to the early 1970s. In part this was due to the application of existing powers provided by Section 54 of the Audit Act 1901. These investigations were termed by the AAO ‘project audits’. Amendments to the Act, in 1979, additionally permitted the AAO to undertake efficiency audits in addition to fiscal regularity audits. The problem, since …

General Practitioners' Views On Patient Care Research., Ian Wilson, B Mcgrath, G Russell, C Bridges-Webb, C Hogan

Ian G Wilson

BACKGROUND: Little research has been undertaken into the factors affecting recruitment by Australian general practitioners of patients for clinical trials. Understanding the differences between recruiters and non-recruiters will assist researchers in better supporting general practitioners involved in such research. METHOD: A survey of general practitioners involved in recruiting patients for clinical trials for the RACGP Research Program was undertaken. RESULTS: Recruiters were more likely to be interested in learning more about research, to perceive involvement as worthwhile, to desire a good relationship with Research Program staff and to feel the doctor-patient relationship assists recruitment. DISCUSSION: Recruiters in general are average …

Post-Traumatic Stress Disorder In A Group Of Australian General Practices., Charis Gauvin, Ian Wilson

Ian G Wilson

Some authorities regard post-traumatic stress disorder (PTSD) as a well characterised condition that is under diagnosed in general practice. We aimed to explore its prevalence in Australian general practice. METHOD: 'Medic-GP' contains the records of 58,941 patients over a period of six years. We searched the database for PTSD and synonyms in individual records, looking for diagnostic criteria and comorbidities. RESULTS: Post-traumatic stress disorder was diagnosed in 337 patients, an annual incidence of 88/100,000 patients over a 6.5 year period. Specialists diagnosed 312 (93%) after referral by general practitioners. The GPs diagnosed 25 (7%) themselves, of whom only five patients …

The Management Of Bipolar Disorder In General Practice, Phillip Mitchell, Jillian Ball, James Best, Bronwyn Gould, Gin Malhi, Geoffrey Riley, Ian Wilson

Ian G Wilson

•General practitioners have a key role in managing patients with bipolar disorder, a condition which affects at least one in 200 Australians each year and is the sixth leading cause of disability in the population. • Although diagnosis and treatment of the illness is complex, effective treatment can lead to good outcomes for many patients. • GPs can contribute significantly to early recognition of bipolar disorder, avoiding the long delays in accurate diagnosis that have been reported. As in other complex recurrent or persistent illnesses, GPs are well placed to coordinate multidisciplinary "shared care" with specialists and other health care …

General Practice Training And Virtual Communities Of Practice - A Review Of The Literature, Stephen Barnett, Sandra C. Jones, Sue Bennett, Donald C. Iverson, Andrew D. Bonney

Don C. Iverson

Background: Good General Practice is essential for an effective health system. Good General Practice training is essential to sustain the workforce, however training for General Practice can be hampered by a number of pressures, including professional, structural and social isolation. General Practice trainees may be under more pressure than fully registered General Practitioners, and yet isolation can lead doctors to reduce hours and move away from rural practice. Virtual communities of practice (VCoPs) in business have been shown to be effective in improving knowledge sharing, thus reducing professional and structural isolation. This literature review will critically examine the current evidence …

General Practice Training, Web 2.0 And Virtual Communities Of Practice: An Interview Study, Stephen Barnett, Sandra Jones, Lance Barrie, Andrew Bonney, Donald Iverson

Don C. Iverson

Aims and Rationale General Practice training faces geographic barriers to efficient knowledge sharing, collaboration and professional and social support amongst its participants. In industry, large companies use internet tools to create Virtual Communities of Practice which improve collaboration, information sharing and support amongst staff. This study examined the feasibility of using Web 2.0 tools to create a Virtual Community of Practice for GP training. Methods Following a previous quantitative survey study, a qualitative telephone interview study was undertaken with GP Registrars and Supervisors in a Regional Training Provider. Participants were selected on the basis of highest internet usage in the …

Aggregation And Law, Ariel Porat, Eric Posner

Ariel Porat

If a plaintiff brings two claims, each with a 0.4 probability of being valid, the plaintiff will usually lose, even if the claims are based on independent events, and thus the probability of at least one of the claims being valid is 0.64. If a plaintiff brings two independent claims, and neither of them alleges misconduct sufficient to justify a remedy, the plaintiff will usually lose, even if the claims jointly allege sufficient wrongdoing to justify a remedy. Thus, as a general rule, courts refuse to engage in what we call factual aggregation (the first case) and normative aggregation (the …

There are 17 known X-ray transients within the field of view of our campaign, eight of which were detected in outburst during our observations: the transient neutron star low-mass X-ray binaries GRS 1741-2853, AX J1745.6-2901, SAX J1747.0-2853, KS 1741-293 …

Design And Analysis Of General And Travelling Dielectrophoresis, T. Kinkeldei, W.H Li

Professor Weihua Li

This paper presents the simulation of general and travelling dielectrophoretic forces, as well as the movement of the particles in a sandwich structure micro-device. The electrode geometry of the micro device used for simulation is an interdigitated bar electrode. The simulation method used to solve the equations is based on the least square finite difference method (LSFD). The simulation first calculates all forces acting at any place in the chamber, with these forces the trajectory of a particle can now be proposed. All of the particles parameters like radius, voltage, initial height, etc can easily be changed and the simulation …

New General Algorithm For Describing Manipulator Kinematics, Christopher Cook, T Vu-Dinh

Christopher Cook

A new algorithm for representing the kinematic problem of robot arms is presented, and its advantages discused. It is shown that manipulator links and joints can be described using generalised cascaded 'robot joint descriptors'. Such a description provides a theoretical basis for the development of a kinematic controller applicable to most manipulator geometries.
