BACKGROUND General practitioners (GPs) can play an important role in both the prevention and management of overweight and obesity. Current general practice guidelines in the Netherlands allow room for GPs to execute their own weight management policy. OBJECTIVE To examine GPs' current weight management policy and the factors associated with this policy. METHODS 800 Dutch GPs were asked to c...

BACKGROUND No global positioning system (GPS) technology study has been conducted among a sample of young gay, bisexual, and other men who have sex with men (YMSM). As such, the purpose of this study was to evaluate the feasibility and acceptability of using GPS methods to understand the spatial context of substance use and sexual risk behaviors among a sample of YMSM in New York City, a high-r...

OBJECTIVE To examine the demographic changes in the cohort of general practitioners servicing residential aged-care facilities (RACFs) from 1984 to 2000. DESIGN Quantitative analysis of Medicare datasets from 1984 to 2000. PARTICIPANTS AND SETTING All GPs who provided Medicare-claimed RACF services from 1984 to 2000. MAIN OUTCOME MEASURES Aggregate data on RACF GPs by age group and sex; t...

OBJECTIVE To assess general practitioners' (GPs') information-seeking behaviour and perceived importance of sources of scientific medical information and to investigate associations with GP characteristics. DESIGN A national cross-sectional survey was distributed electronically in December 2013. SETTING Danish general practice. SUBJECTS A population of 3440 GPs (corresponding to approxima...

OBJECTIVE Personality disorders (PDs) often remain unrecognized in older adults by doctors in general practice. Therefore, this study evaluated the diagnostic accuracy of a screening instrument, the Gerontological Personality Disorder Scale (GPS), in a Dutch general-practice population of older adults. METHOD The psychometric properties of the GPS patient (GPS-pv) and informant (GPS-iv) versi...

Next generation GPS receivers will take advantage of Spatial processing from a Controlled Reception Pattern Antenna (CRPA) and Ultra-Tightly-Coupled (UTC) and Tightly–Coupled GPS/inertial signal processing to improve their robustness to interference and their performance in a multipath environment. This introduces the potential for failure modes to be introduced into the GPS solution from the S...

The ephemeris data format of legacy GPS receivers is improper for positioning stationary pseudolites on the ground. Therefore, to utilize pseudolites for navigation, GPS receivers must be modified so that they can handle the modified data formats of the pseudolites. Because of this problem, the practical use of pseudolites has so far been limited. This paper proposes a pseudolite-based position...
