BACKGROUND In order to help assess resident performance during training, the Residency Affair Committee of the Pediatric Residency Program of the University of Padua (Italy) administered a Resident Assessment Questionnaire (ReAQ), which both residents and faculty were asked to complete. The aim of this article is to present the ReAQ and its validation. METHODS The ReAQ consists of 20 items th...

In this work, we show that Spearman’s correlation coefficient test about H0:ρs=0 found in most statistical software is theoretically incorrect and performs poorly when bivariate normality assumptions are not met or the sample size small. There common misconception tests ρs=0 robust to deviations from normality. However, under certain scenarios violation of assumption has severe effects on type ...

OBJECTIVE The purpose of this study was to evaluate the frequency and attitude of medical students towards cleaning their stethoscopes. SUBJECTS AND METHODS A cross-sectional study was carried out in the first week of December 2013. The study included 771 students (397 in their fourth and 374 in their sixth year) from the Faculty of Medicine, University of Belgrade, Serbia. An anonymous quest...

BACKGROUND Despite several polysomnographic studies on periodic leg movements (PLM) in healthy sleep, data on the prevalence and characteristics of periodic arm movements (PAM) in normal subjects are lacking. We aimed to investigate PAM and their association with PLM during wakefulness and sleep in healthy subjects. METHODS Ninety-one participants underwent video-polysomnography according to ...

abstract in this research, temporal trends of reference evapotranspiration (et0) values were investigated in arid regions of iran. for this purpose, the meteorological observations collected from 11 high quality meteorological sites for a 41-year period (1965-2005) were used and statistically significant et0 trends in the monthly, seasonal and annual time basis were detected by the non-parametr...

OBJECTIVE US is a promising tool in evaluating RA synovitis, but abnormal US findings have been reported in small subsets of normal joints in healthy subjects. This study aimed to systematically assess greyscale US (GSUS) and power Doppler US (PDUS) findings in 40 peripheral joints-the 28-joint DAS (DAS28) set, ankles and MTP joints-in healthy subjects. A composite score of abnormal US findings...

We propose a CUSUM type test for constant correlation that goes beyond a previously suggested correlation constancy test by considering Spearman’s rho in arbitrary dimensions. By using copula-based expressions, we simultaneously extend a previously suggested copula constancy test. We calculate the asymptotic null distribution using an invariance principle for the sequential empirical copula pro...

Few would dispute the claim that Charles Edward Spearman (1863-1945) is Britain’s premier psychologist and indeed one of the enduring figures in the history of behavioral science. Some twenty years ago, I asked a number of psychologists to list the names of whomever they considered to be the five or six most important persons in the history of psychological testing. Among all the nominations, o...

INTRODUCTION Hair shedding is a common consequence of the normal hair cycle that changes with internal and external factors. Female pattern hair loss (FPHL) is difficult to assess in terms of shedding severity as the conscious perception of hair shedding varies according to each individual, and most utilized methods are semi-invasive or very time consuming. In this study, we establish and valid...

BACKGROUND Rapid growth in global health activity among US medical specialty education programs has lead to heterogeneity in types of activities and global health training models. The breadth and scope of this activity is not well chronicled. METHODS Using a standardized search protocol, we examined the characteristics of US medical residency global health programs by number of programs, clin...
