To investigate the construct validly of a section of a high stakes test, an exploratory factor analysis using principal components analysis was employed. The rotation used was varimax with the suppression level of .30. Eleven factors were extracted out of 35 reading comprehension items. The fact that these factors emerged speak to the construct validity of the test. However the problem of over-...

In this report, we describe a simple correction for multiple testing of single-nucleotide polymorphisms (SNPs) in linkage disequilibrium (LD) with each other, on the basis of the spectral decomposition (SpD) of matrices of pairwise LD between SNPs. This method provides a useful alternative to more computationally intensive permutation tests. A user-friendly interface (SNPSpD) for performing thi...

The Condom Use Self-Efficacy Scale (CUSES) was administered to 447 multicultural college students. The sample consisted of 63.5% Hispanic/Latino, 17.1% African-American, 13.7% Caucasian, 4.1% other and 1.6% Asian students. The obtained scores were subjected to a principal components factor analysis with a Varimax rotation. An item designation criteria was used and three distinct factors were ex...

Results from the Gregorc Style Delineator (GSD), administered to 260 undergraduate nursing students, were compared with achievement scores in a human anatomy and physiology course. Factor analysis and VARIMAX rotation demonstrate that there is no relationship between any of the four learning styles allegedly identified by the GSD and achievement in anatomy and physiology. Factor analysis also s...

Factor analysis was carried out on the National Adult Reading Test (NART) and Wechsler Adult Intelligence Scale (WAIS) performance of 139 normal subjects. The NART loaded very highly on factor I extracted by principal components analysis (PCA), suggesting that the NART has high construct validity as a measure of general intelligence. Varimax rotation of the three factors extracted by PCA produc...

Abstract This work applies a factor analysis with VARIMAX rotation to develop bibliometric indicator, named the Weighted Factor Index, in order derive new classification for journals belonging certain category, alternative one provided by Journal Impact Factor. For this, 16 metrics from three different databases (Web of Science, Scopus and SCImago Rank) are considered. The Weighed Index entails...

BACKGROUND Birth weight is a composite of skeletal size and soft tissue. These components are likely to have different growth patterns. The aim of this paper is to investigate the association between established determinants of birth weight and these separate components. METHODS Weight, length, crown-rump, knee-heel, head circumference, arm circumference, and skinfold thicknesses were measure...

BACKGROUND Work-related fatigue has a strong impact on performance and safety but so far, no agreed upon method exists to detect and quantify it. It has been suggested that work-related fatigue cannot be quantified with just one test alone, possibly because fatigue is not a uniform construct. The purpose of this study is therefore to measure work-related fatigue with multiple tests and then to ...
