The authors sought to replicate and extend the work of E. Rosch Heider (1972) on the Dani with a comparable group from Papua, New Guinea, who speak Berinmo, which has 5 basic color terms. Naming and memory for highly saturated focal, non-focal, and low-saturation stimuli from around the color space were investigated. Recognition of desaturated colors was(More)
A new generic model for assessing the viability of spatially structured populations, ALEX (Analysis of the Likelihood of EXtinction), is described. Strengths and weaknesses of ALEX are discussed. ALEX only models one sex, ignores genetics, and is inadequate for modelling the dynamics of very small populations. However ALEX contains four features that make(More)
BACKGROUND Personal Health Records (PHRs) are electronic health records controlled, shared or maintained by patients to support patient centered care. The potential for PHRs to transform health care is significant; however, PHRs do not always achieve their potential. One reason for this may be that not all health conditions are sensitive to the PHR as an(More)
This study investigated the phenomenon of temporal summation in response to repetitive focused ultrasound stimulation of skin, muscle and joint in human volunteers. Stimulation was carried out using a custom-designed, focused ultrasonic stimulator with a resonant frequency of 1.66 MHz. A series of stand-off attachments were used to ensure that the focal(More)
Cerebral activity, as reflected by power in the alpha waveband (8-13 Hz), was examined prior to the performance of three tasks with different effort and accuracy requirements. The study aimed to further investigate changes in activity observed in an earlier study in which expert karate performers exhibited significant increases in alpha band power during(More)
Improvements in medication management may lead to a reduction of preventable errors. Usability and user experience issues are common and related to achieving benefits of Electronic Medical Records (EMRs). This paper reports on a novel study that combines the lead user method with a safety engineering review to discover an innovative design for the(More)
Pain was induced in the proximal interphalangeal joint of the index finger in human volunteers using a high powered focused ultrasonic generator. Eighty, 100 ms pulses were applied during each test. This test was repeated at hourly intervals for a period of 5 h. A brain evoked potential with a characteristic wave form was recorded, resulting from the(More)
The reproducibility of focussed ultrasound-induced intra-articular pain was compared with that of electrically induced cutaneous pain over a period of time by measuring both the evoked potential (EP) amplitude and visual analogue scale (VAS) score. The responses to ultrasound were more variable than those to electrical stimulation. A greater degree of(More)
