a valid questionnaire is a precursor to a sound measurement process. this study examined the psychometric properties of the persian version of the revised competitive state anxiety inventory – 2 (csai-2r). a total of 131 female taekwondo athletes (mean age =12.37 ± 2.52) from damghan completed csai-2r at competition venues. confirmatory factor analysis was used to analyze the structure of csai-...

The purpose of this study was to use confirmatory factor analysis (CFA) to revise the factor structure of the CSAI-2 using one data set, and then to use CFA to validate the revised structure using a second data set. The first data set (calibration sample) consisted of 503 college-age intramural athletes, and the second (validation sample) consisted of 331 intercollegiate (Division I) and inters...

valid objective measure that can be easily carrying for assessment of  competitive anxiety is not available in iran. competitive state anxiety inventory-2r (csai-2r) is introduced as a quick and easy diagnostic tool for competitive anxiety. the aim of this study was to determine the psychometric properties of csai-2r in the part of iranian society. the study population included all volleyball, ...

Objectives: Given recent concerns regarding its validity the aim of the present study was to examine the capability of the Competitive State Anxiety Inventory-2(d) (CSAI-2(d)) in distinguishing between anxious and excited states. Design and Methods: British university athletes (n 188) were randomly assigned to one of two groups and asked to complete the CSAI-2(d) as if they were either excited ...

BACKGROUND In neonates, it is challenging to diagnose aortic coarctation in the setting of a patent ductus arteriosus (PDA). Frequently, serial echocardiograms are performed, and diagnosis is delayed until the PDA closes. The purpose of this study was to identify echocardiographic predictors of neonatal coarctation in the presence of a PDA in cases in which diagnosis is uncertain. METHODS We ...

The current research shows that people differ in their inclination to use positive self-images when their self is threatened (i.e., cognitive self-affirmation inclination, CSAI). Just as self-affirmation manipulations do, the use of positive self-images induces open mindedness towards threatening messages. The aim of the current studies was to show the meaning, stability, and effects of this ne...

Right ventricular outflow tract obstruction was relieved by placing outflow patches across the pulmonary annulus in 39 of 195 patients who underwent total correction of tetralogy of Fallot. The mortality rate in these 39 patients was 12.8%, which did not differ significantly from the overall mortality of 11.3% (p = 1.00). The ratio of the pulse pressure to pulmonary artery systolic pressure as ...

Pseudomonas chlororaphis subsp. aurantiaca StFRB508 regulates phenazine production through N-acyl-l-homoserine lactone (AHL)-mediated quorum sensing. Two sets of AHL-synthase and AHL-receptor genes, phzI/phzR and aurI/aurR, have been identified from the incomplete draft genome of StFRB508. In the present study, the complete genome of StFRB508, comprising a single chromosome of 6,997,933 bp, was...

This paper examines procedural modeling as a tool for 3D modeling creation. Procedural modeling historically has been used for 3D visualization of natural features, but with the release of the software CityEngine in 2008, the technology can easily be adopted also in problem domains dealing with urban environments. Then, we will examine and compare two types of modeling, traditional and proc...
