background: sustained visual attention is a prerequisite for learning and memory. the early evaluation of attention in childhood is essential for their school and career success in the future. the aim of this study was to design, development and investigation of psychometric properties (content, face and convergent validity and test-retest and internal consistency reliability) of the computer -...

This paper introduces a causation coefficient which is defined in terms of probabilistic causal models. This coefficient is suggested as the natural causal analogue of the Pearson correlation coefficient and permits comparing causation and correlation to each other in a simple, yet rigorous manner. Together, these coefficients provide a natural way to classify the possible correlation/causation...

Antibiotic consumption and population density as a measure of crowding in the community were related to the prevalence of antibiotic resistance of three cities in three different countries: St Johns in Newfoundland (Canada), Athens in Greece and Groningen in The Netherlands. Antibiotic consumption was expressed in DDD (defined daily dose), as DID (DDD/1000 inhabitants/day) and as DSD (DDD/km(2)...

For clarity, the Pearson R and R are given in Table 1 below for all the theoretical cases posed. It corrects the correlation coefficients in Figure 3 and in the discussion of signal over noise in the “Strengths and Weaknesses” section. It should be noted that our use of R is based on squaring the Pearson value, not based on a calculation of the coefficient of determination (also called R). The ...

OBJECTIVE This study was conducted to assess the reproducibility and validity of a food frequency questionnaire (FFQ) that was developed to assess the overall dietary consumption via dietary pattern method in a rural population in southwest China. METHODS A total of 179 participants aged between 40 and 70 years old were included in this study. Participants administered FFQ at baseline (FFQ1) ...

BACKGROUND The hand-behind-back method is the accepted technique to evaluate shoulder internal rotation, is highly popular, and is endorsed by the American Academy of Orthopaedic Surgeons. It remains, however, subject to intra- and interexaminer discrepancy and has been challenged by several recent publications. HYPOTHESIS Internal rotation behind the back can be evaluated with a measurable a...

objective: the self-compassion scale (scs) which originally developed by neff (2003a) is based on the assumption that the self-compassion comprised by self-kindness/self-judgment, common humanity/perceived isolation, and mindfulness/over-identification. this research was aimed to confirm the six-factor structure of scs. methods: 265 university students entered the research to assess the psychom...
