OBJECTIVE To determine the prevalence of patient-initiated aggression toward general practitioners in Australia. DESIGN, SETTING AND PARTICIPANTS A cross-sectional national survey, conducted during February-May 2010, of 3090 GPs in 19 Divisions of General Practice, purposively sampled to represent urban, rural and remote areas. MAIN OUTCOME MEASURE Proportion of GPs experiencing patient-ini...

In the framework of the GRIM series of gravity field models, the CNES/GRGS GINS precise orbit determination software has been adapted to dynamic GPS data processing. That is simultaneous processing of all available observables (i.e. GPS, DORIS, Laser) and all available satellite orbits (i.e. GPS, TOPEX/POSEIDON) can now be performed. The TOPEX/POSEIDON (T/P) mission satellite is equipped with a...

BACKGROUND GPs typically sanction absence from work by issuing sickness certificates. There has been some debate recently about changing the way sickness certificates are issued and by whom. However, without understanding GPs' certification practices, their requirements in terms of training and education and how they feel the certification process should or should not be changed, measures aimed...

OBJECTIVE The aim of this study is to analyse the interaction between patients and GPs in preventive consultations with an emphasis on how patients answer GPs' questions about lifestyle, and the conditions these answers impose on the process of establishing agreement about lifestyle as a problem or not. DESIGN Six general practitioners (GPs) video-recorded 15 annual preventive consultations. ...

OBJECTIVE To compare the quality of care provided by general practitioners participating in diabetes shared-care registers with that provided by GPs not using registers. DESIGN Cross-sectional comparison using Health Insurance Commission (HIC) data for patients attending the GPs. PARTICIPANTS AND SETTING 155 GPs using diabetes registers, 459 GPs not using registers, and their patients with ...

BACKGROUND GPs are the health professionals most frequently consulted by adolescents. However, discussion between GPs and adolescents regarding cannabis use does not occur spontaneously. OBJECTIVE To identify obstacles to the identification and management of cannabis use by adolescents based on GPs' experiences. METHODS We conducted a qualitative study using focus groups of GPs from the Auv...

We propose Direct Position Estimation (DPE) utilizing non-line-of-sight (NLOS) GPS signals for urban navigation. In urban environments, buildings reflect GPS signals, leading to reception of NLOS GPS signals. In addition, buildings obstruct GPS signals, resulting in reduced GPS signal availability. We treat NLOS GPS signals as additional line-of-sight (LOS) GPS signals to virtual satellites at ...

The Global Positioning System (GPS) has slowly permeated into the civilian community and has become an essential accessory for the modern individual. Various commercial applications heavily rely on GPS technology. GPS has also started receiving attention in court cases, where it has been admissible as evidence leading to convictions or proving innocence. However, GPS is a radio-navigation syste...

GPS receivers are widely used in navigation and positioning, due to the global availability of GPS signals, its low cost and low power consumption. However, it does not work sufficiently in all signal environments. This raises the need to integrate GPS with other sensor systems (for instance, the inertial navigation system (INS)) to have a robust, continuous navigation solution regardless of th...

Next-generation transportation surveys will utilize Global Positioning Systems (GPS) to collect trip data. Due to their ubiquity, GPS-enabled mobile devices are becoming promising for use as survey tools. TRAC-IT is a mobile phone application that records travel behavior by collecting real-time GPS data and requiring minimal input from the user for data such as trip purpose, mode of transportat...
