Repetition blindness (RB) is the finding that observers often miss the repetition of an item within a rapid stream of words or objects. Recent studies have shown that RB for objects is largely unaffected by variations in viewpoint between the repeated items. In 5 experiments, we tested RB under different axes of rotation, with different types of stimuli (line drawings and shaded images, intact ...

objective: health and medicare issue plays a vital role in socio-economic life of the people in any society. that is why most of the economic planners expect much more from public health sector, including creating jobs, revenues and healthy social opportunities in addition to basic health necessities. the main objective of the present study is to measure the level of development of different pr...

the present study aimed at validating the structure of career decision-making difficulties questionnaire (cddq).five hundred and eleven undergraduate students took part in this research; from these participants, 63 males and 200 females took part in the first study, and 63 males and 185 females completed the survey for the second study.the results of exploratory factor analysis (efa) indicated ...

background: the aim of this study was to investigate the psychometric properties of social capital questionnaire (scq) developed by onyx and bullen (2000) among a sample of medical science students in tehran university of medical sciences, iran and to compare the factor analysis with findings from two previous studies in australia and the united states. methods: multistage cluster sampling was ...

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-...

Factor analysis and principal component analysis result in com-puting a new co-ordinate system, which is usually rotated to ob-tain a better interpretation of the results. In the present paper, theidea of rotation to simple structure is extended to two dimensions.While the classical definition of simple structure is aimed at rotat-ing (one-dimensional) factors, the extension...

Eukaryotic ribosomes assemble by association of ribosomal RNA with ribosomal proteins into nuclear precursor particles, which undergo a complex maturation pathway coordinated by non-ribosomal assembly factors. Here, we provide functional insights into how successive structural re-arrangements in ribosomal protein S3 promote maturation of the 40S ribosomal subunit. We show that S3 dimerizes and ...

We present the results of a principal-components analysis of the Personality Adjective Check List (PACL) at the item level, rather than at the scale level. The PACL was constructed by Strack (1987) to evaluate the personality scales proposed by Millon (1981). Data were obtained from a sample of normal adolescents. A scree test was applied to determine the number of factors to be extracted, and ...

Steinhaus asked whether there exists a subset of the plane which, no matter how translated and rotated, always contains exactly one point with integer coordinates. It is still unknown if there exist sets with the Steinhaus property. Using harmonic analysis we prove that if a measurable set S R 2 satisses R S jxj 10 3 + dx < 1, for some > 0, then it cannot have the Steinhaus property. 0. Introdu...
