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…

Ordinary least squares (OLS) regression and orthogonal regression (OR) address different questions and make different assumptions about errors. The OLS regression of Y on X yields predictions of a dependent variable (Y) contingent on an independent variable (X) and minimizes the sum of squared errors of prediction. It assumes that the independent…

Data collected from surveys can result in hundreds of variables and thousands of respondents. This implies that time and energy must be devoted to (a) carefully entering the data into a database, (b) running preliminary analyses to identify any problems (e.g., missing data, potential outliers), (c) checking the reliability and validity of the…

This study sought to investigate the effect of adapted physical education (APE) courses and practica on pre-service teachers' self-efficacy (SE) towards inclusive physical education (PE) for students with intellectual disability (ID) and autism. Three hundred and fifty-six students (male = 254, female = 102) enrolled in adapted physical education…

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…

Based upon self-concept and self-determination theory, the present study aimed to examine the measurement separability of young children's math self-concept (MSC) and six specific types of motivation, namely, intrinsic motivation (INTR), integrated motivation (INTEG), identified motivation (IDENT), introjected motivation, extrinsic motivation…

Relying on Bandura's (1986) social learning theory, Ajzen's (1988) theory of planned behaviour (TPB), and Dyer's (1994) model of entrepreneurial careers, this study aims to highlight the potential of entrepreneurial role models to entrepreneurship education. The results suggest that entrepreneurial courses would greatly benefit from real-life…

The landscape of higher education is changing. More diverse students are attending universities at higher numbers, yet these students are not graduating. This quantitative study uses linear regression, stepwise regression, and then exploratory factor analysis to examine three constructs--hope, academic self-efficacy, and sense of belonging--in…
