This paper presents a method for analyzing oral examinations with an extended, many-faceted Rasch model that calibrates medical specialty candidates, protocols, and raters. Significant variance was found among protocol difficulties and rater severities. When candidates' raw scores were compared with calibrated measures corrected for the bias caused by the particular protocols and raters encount...

drought is a normal, recurring feature of climate phenomena; it may occur virtually in all climatic regions. the effects of drought accumulate slowly and its impacts are spread over a larger geographical area than other natural hazards. drought is a natural hazard originating from a deficiency of precipitation that result in a water shortage for some activities or some groups and is often assoc...
