Pbtrust: A Priority-Based Trust Model For Service Selection In General Service-Oriented Environments, Xing Su, Minjie Zhang, Yi Mu, Kwang Mong Sim Dec 2012

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 …

Voltage Unbalance Emission Limits For Installations: General Guidelines And System Specific Considerations, Robert Koch, Alexander Baitch, Sarath Perera, Prabodha Paranavithana Nov 2012

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 …

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 Nov 2012

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 Nov 2012

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.


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 Oct 2012

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 …


Aggregation And Law, Ariel Porat, Eric Posner Oct 2012

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 …

We report on the results of a four-year long X-ray monitoring campaign of the central 1.2 square degrees of our Galaxy, performed with Chandra and XMM-Newton between 2005 and 2008. Our study focuses on the properties of transient X-ray sources that reach 2-10 keV luminosities of LX ≳ 1034 erg s-1 for an assumed distance of 8 kpc. 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 Aug 2012

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 …

Physics and Astronomy Faculty Research Publications

The spin of Cygnus X-1 is measured by fitting reflection models to Suzaku data covering the energy band 0.9-400 keV. The inner radius of the accretion disc is found to lie within 2 gravitational radii (rg=GM/c2), and a value of ? is obtained for the dimensionless black hole spin. This agrees with recent measurements using the continuum fitting method by Gou et al. and of the broad iron line by Duro et al. The disc inclination is measured at ?, which is consistent with the recent optical measurement of the binary system inclination by Orosz et …


What Do Older Patients Want? Understanding Older Patients' Attitudes Towards General Practice Trainees, Andrew D. Bonney, Sandra C. Jones, Donald Iverson, Christopher Magee Jun 2012

What Do Older Patients Want? Understanding Older Patients' Attitudes Towards General Practice Trainees, Andrew D. Bonney, Sandra C. Jones, Donald Iverson, Christopher Magee

Don C. Iverson

Context: Older patients constitute an increasing proportion of the caseloads in general practice (GP) training practices, but are relatively reluctant to consult trainees. Understanding their attitudes is a first step in improving older patient-trainee interaction. Objectives: Characterise the attitudes of older patients to GP trainees. Design: Cross-sectional survey; exploratory factor analysis; logistic regression. Setting: Randomised, stratified sample of 38 training practices across five Australian states. Participants: Patients aged 60 years and over (N=911; response rate 47.9%). Instrument: Questionnaire for self-completion: previously piloted and subjected to factor analysis. Main and secondary outcome measures: Identification of attitude factors; patient characteristics predicting high …


General Practice Registrars: Attitudes Of Older Patients, Andrew D. Bonney, Sandra C. Jones, Lyn Phillipson, Donald C. Iverson Jun 2012

General Practice Registrars: Attitudes Of Older Patients, Andrew D. Bonney, Sandra C. Jones, Lyn Phillipson, Donald C. Iverson

Don C. Iverson

Previous research indicates that older patients may be less willing to consult general practice registrars (GPRs), reducing training opportunities in chronic/complex care. This survey explores older patients’ attitudes in order to inform models of interaction that would be acceptable to patients. METHODS Ten training general practices distributed questionnaires for self completion to 50 patients aged 60 years and over. Chi-square, Spearman’s rho and logistic regression were used for analysis. RESULTS The response rate was 47%. Ninetysix percent wanted ongoing contact with their general practitioner if they saw a GPR. Twenty-four percent were comfortable with GPR chronic/complex care, increasing to 73% …


Preparing For An Ageing Population: A Survey Of Older Patients' Attitudes To General Practice Registrars, Andrew D. Bonney, Sandra C. Jones, Lyn Phillipson, Donald C. Iverson Jun 2012

Preparing For An Ageing Population: A Survey Of Older Patients' Attitudes To General Practice Registrars, Andrew D. Bonney, Sandra C. Jones, Lyn Phillipson, Donald C. Iverson

Don C. Iverson

The ageing population makes it imperative to provide appropriate training for general practice registrars (GPRs) in the community-based care of older patients. However, data suggest that older patients may be less willing to consult GPRs for chronic/complex care; adversely affecting training opportunities and potentially the satisfaction of older patients in training practices. This cross-sectional study was undertaken to investigate this concern in the Australian context and develop models of older patient-GPR interaction that are acceptable to patients.

A Chandra Survey Of Supermassive Black Holes With Dynamical Mass Measurements, Kayhan Gültekin, Edward M. Cackett, Jon M. Miller, Tiziana Di Matteo, Sera Markoff, Douglas O. Richstone

Physics and Astronomy Faculty Research Publications

We present Chandra observations of 12 galaxies that contain supermassive black holes (SMBHs) with dynamical mass measurements. Each galaxy was observed for 30 ks and resulted in a total of 68 point-source detections in the target galaxies including SMBH sources, ultraluminous X-ray sources (ULXs), and extragalactic X-ray binaries. Based on our fits of the X-ray spectra, we report fluxes, luminosities, Eddington ratios, and slope of the power-law spectrum. Normalized to the Eddington luminosity, the 2-10 keV band X-ray luminosities of the SMBH sources range from 10-8 to 10-6, and the power-law slopes are centered at ~2 with …

[1] The goal of this study is to determine how H2O and HDO measurements in water vapor can be used to detect and diagnose biases in the representation of processes controlling tropospheric humidity in atmospheric general circulation models (GCMs). We analyze a large number of isotopic data sets (four satellite, sixteen ground-based remote-sensing, five surface in situ and three aircraft data sets) that are sensitive to different altitudes throughout the free troposphere. Despite significant differences between data sets, we identify some observed HDO/H2O characteristics that are robust across data sets and that can be used to evaluate models. We evaluate …

The Hollow-Face Illusion: Object Specific Knowledge, General Assumptions Or Properties Of The Stimulus, Harold C. Hill, Alan Johnston Jan 2012

The Hollow-Face Illusion: Object Specific Knowledge, General Assumptions Or Properties Of The Stimulus, Harold C. Hill, Alan Johnston

Harold Hill

The hollow-face illusion, in which a mask appears as a convex face, is a powerful example of binocular depth inversion occurring with a real object under a wide range of viewing conditions. Explanations of the illusion are reviewed and six experiments reported. In experiment 1 the detrimental effect of figural inversion, evidence for the importance of familiarity, was found for other oriented objects. The inversion effect held for masks lit from the side (experiment 2). The illusion was stronger for a mask rotated by 90° lit from its forehead than from its chin, suggesting that familiar patterns of shading enhance …

An Investigation Of Non-Spatial Cognitive Abilities In An Asocial Corvid, The Clark's Nutcracker (Nucifraga Columbiana), Jan K. Tornick Jan 2012

An Investigation Of Non-Spatial Cognitive Abilities In An Asocial Corvid, The Clark's Nutcracker (Nucifraga Columbiana), Jan K. Tornick

Doctoral Dissertations

A great deal of research suggests that the cognitive abilities of birds in the family Corvidae (crows and jays) are comparable in many aspects to that of apes. Scientists have posited competing hypotheses to explain how complex cognitive abilities arise in a species or group of animals. One such hypothesis, the social-intelligence hypothesis, states that the demands of living in a large, dynamic group drive an animal's need for complex cognitive skills. The ecological-intelligence hypothesis, predicts that generalist foragers develop more highly flexible behaviors and a wider cognitive repertoire than specialist foragers. To date, cognitive research on corvids has focused …


Anxious Lives: Tracing The Life Course Of A Medical Diagnosis Through Illness Narratives, Jennifer J. Esala Jan 2012

Anxious Lives: Tracing The Life Course Of A Medical Diagnosis Through Illness Narratives, Jennifer J. Esala

Doctoral Dissertations

This dissertation is a study of medical diagnosis, specifically anxiety disorder diagnosis, from the perspective and through the narratives of people who have been diagnosed. In this study, I address two core research questions. First, how does social materiality (e.g., bodies and objects) contribute to, shape, and lend empirical understanding to the experience of an anxiety disorder and the experience of illness in general? Second, how does medical diagnosis translate from the medical institution into the lives of people who have been diagnosed, and how do those diagnoses transform in and through the social lives of people? To address these …
