Sleepiness is a major risk factor for serious injury and death in accidents. Although it is important to develop countermeasures to sleepiness to reduce risks, it is equally important to determine the most effective timing for these countermeasures. To determine optimum timing for necessary countermeasures, we must be able to predict performance errors. This study examined the predictability of...

In this work we study the vibrato rate, extent and intonation in Byzantine Music. Two methods of analysis have been applied: the first based on the analytical signal and the second on the crests and troughs of the waveform of the vibrato signal. Tones samples were extracted from ascending and descending music scales, chanted by five famous singers for all the Greek vowels. The two analysis meth...

The study was conducted to provide an acoustic description of coronal stops in Canadian English (CE) and Canadian French (CF). CE and CF stops differ in VOT and place of articulation. CE has a two-way voicing distinction (in syllable initial position) between simultaneous and aspirated release; coronal stops are articulated at alveolar place. CF, on the other hand, has a two-way voicing distinc...

BACKGROUND We wished to compare the nuisance parameters of pediatric vs. adult randomized-trials (RCTs) and determine if the latter can be used in sample size computations of the former. METHODS In this meta-epidemiologic empirical evaluation we examined meta-analyses from the Cochrane Database of Systematic-Reviews, with at least one pediatric-RCT and at least one adult-RCT. Within each meta...

OBJECTIVE To determine the psychometric properties of the Neck Bournemouth Questionnaire in patients with chronic neck pain, using Rasch analysis. METHODS A sample of 161 subjects with chronic neck pain was assessed with the Neck Bournemouth Questionnaire. Before performing Rasch analysis, we examined the structure of the scale with factor analysis. The goodness-of-fit of the data to the mode...

OBJECTIVE This study explored the effects of a cognitive task analysis (CTA)-informed curriculum to increase surgical skills performance and self-efficacy beliefs for medical students and postgraduate surgical residents learning how to perform an open cricothyrotomy. METHODS Third-year medical students and postgraduate year 2 and 3 surgery residents were assigned randomly to either the CTA gr...
