Including a large number of predictors in the imputation model underlying a multiple imputation (MI) procedure is one of the most challenging tasks imputers face. A variety of high-dimensional MI techniques can help, but there has been limited research on their relative performance. In this study, we investigated a wide range of extant…

Regression factor score predictors have the maximum factor score determinacy, that is, the maximum correlation with the corresponding factor, but they do not have the same inter-correlations as the factors. As it might be useful to compute factor score predictors that have the same inter-correlations as the factors, correlation-preserving factor…

This study conceptualizes lexical sophistication as a multidimensional phenomenon by reducing numerous lexical features of lexical sophistication into 12 aggregated components (i.e., dimensions) via a principal component analysis approach. These components were then used to predict second language (L2) writing proficiency levels, holistic lexical…

Human behaviours in organisations are closely associated with leadership styles. The main purpose of this study is to find out the relationship between teachers' perception about multi-frame leadership orientations of principals and teachers' emotional labour. The study is based on Bolman and Deal's Four Frames Model, and, therefore, the…

The current research examined the psychometric properties and utility of a measure of college classroom environment in predicting goal-related outcomes rooted in goal contents and achievement goal theories. Exploratory and confirmatory factor analyses in Studies 1 and 2, respectively, yielded support for two distinct and gender-invariant classroom…

The development of e-learning and digital campus has prompted more and more teachers to assign online homework to students. Consequently, teachers need to provide sufficient and relevant guidance for such homework. Teachers' online homework guidance (TOHG) is conceptually connected with their level of technological pedagogical content knowledge…

The primary aim of this study was to examine the structure of processing speed (PS) in middle childhood by comparing five theoretically driven models of PS. The models consisted of two conceptual models (a unitary model, a complexity model) and three methodological models (a stimulus material model, an output modality model, and a timing modality…

The aim of this study is to investigate the blind and constructive patriotism tendencies of university students in light of the demographic structure and variables. The investigation is performed by using the correlational descriptive model. The purposeful sampling technique has been used and data was collected from a total of 390 university…

The current study uses a sample of community colleges to explore the specific organizational practices that mediate the link between entrepreneurial orientation and performance. The study focuses on a set of practices known as strategic enrollment management and finds that a college's entrepreneurial orientation predicts its enrollment management…

Teachers, especially their teaching behaviours, play an important role in students' learning and students with a high interest in learning show deeper understanding in the classroom. This study intends to explore how far the teacher's charisma--knowledge, character traits, teaching techniques and humour--contribute to students' interest in…

In this study, we concurrently investigated 3 possible causes of dyslexia--a phonological deficit, visual stress, and a reduced visual attention span--in a large population of 164 dyslexic and 118 control French children, aged between 8 and 13 years old. We found that most dyslexic children showed a phonological deficit, either in terms of…
