The purpose of this study was to explore the effect of actively constructing virtual patient (VP) cases compared with solving VP cases on knowledge gains, skills transfer and time spent on cases. Forty-five fourth-year medical students were randomized to constructing (VP-construction, n = 23) or solving (VP-solving, n = 22) four cardiopulmonary VP cases. Whereas the VP-solving group solved the ...

A classification of channel-reach morphology in mountain drainage basins synthesizes stream morphologies into seven distinct reach types: colluvial, bedrock, and five alluvial channel types (cascade, step pool, plane bed, pool rime, and dune ripple). Coupling reach-level channel processes with the spatial arrangement of reach morphologies, their links to hillslope processes, and external forcin...

A major need of precision-oriented retrieval systems is the availability of high-level indexing languages which can allow the representation and the manipulation of elaborated concepts for both indexing and querying processes. Such elaborated knowledge representations, as the one developed in the RIME project, need in turn to be fully integrated within the underlying retrieval model to ensure p...

This paper presents an analysis of the distribution of phonological similarity relations among monosyllabic spoken words in English. It differs from classical analyses of phonological neighborhood density (e.g., Luce & Pisoni, 1998) by assuming that not all phonological neighbors are equal. Rather, it is assumed that the phonological lexicon has psycholinguistic structure. Accordingly, in addit...

Reactive infectious mucosal eruptions (RIME) following Chlamydia pneumoniae infection is a rare and poorly understood clinical presentation that can pose diagnostic challenge. We report the case of previously healthy 21-year old male with cough, fever, numerous penile mouth ulcers, severe conjunctivitis. Several differential diagnoses, including Herpes simplex infection, were considered before ...
