The purpose of this study is to examine the effect of missing data imputation methods, namely regression imputation (RI), multiple imputation (MI) and k-nearest neighbor (kNN) on differential item functioning (DIF). In this regard, the datasets used in the research were created by deleting some of the data via the missing completely at random…

College students today are much more diverse in their needs than in the past (e.g., they may live off campus, work full or part time, and seek ways to lessen college-related debt). Institutions of higher education are seeking ways to more effectively reach this diverse student population, often through online education. Institutions also realise…

The DigiLit Framework suggests criteria for digital text and tool selection (content accuracy, intuitiveness, interactivity, quality) and integration (model a literacy skill or strategy, guide a literacy skill or strategy, model digital feature use, guide digital feature use) in literacy lessons. Using survey research, we explored which DigiLit…

Sensory processing differences measured by self- or parent-report co-segregate with quantitative autistic traits and have potential endophenotypic properties. It is not known to what extent this reflects generalized sensory dysfunction versus more specific associations involving individual senses or autistic trait domains. We combined Bayesian…

Autistic individuals have reported lower satisfaction in their romantic relationships compared to non-autistic individuals. Previous research on the factors that contribute to relationship satisfaction within autism has focused on the characteristics of autistic participants as barriers to relationship satisfaction, while overlooking the role of…

Background: Individuals pursue teaching careers for numerous reasons, such as for instrumental or prosocial purposes. Aims: This study examined the personal (instrumental motivation) and social (prosocial motivation) utility of teaching as predictors of teaching quality in terms of clarity of instruction, classroom management, and cognitive…

Research on contract cheating usually considers most forms of outsourcing combined, although studies have found that students more commonly obtain work from those known to them, rather than from commercial sites; yet little research exists which explores which variables and motivators may be associated with this type of outsourcing. Strategies…

The Existential Model of Perfectionism and Depressive Symptoms (EMPDS) is a promising integrative model. According to the EMPDS, self-oriented perfectionism and socially prescribed perfectionism indirectly influence depressive symptoms through rumination and difficulty accepting the past. Yet, the extent to which self-oriented perfectionism,…

The aim of the current study was to extend knowledge of occupational commitment by examining predictors at the teacher- and school-level. Several job resources hypothesized to be positively associated with occupational commitment were examined: helpful feedback, input in decision-making, teacher collaboration, and principal discipline support. The…

Background: There is a need to systematically compare and contrast mortality predictors and disparities in people with intellectual disabilities (ID) for global prevention strategy development. Method: Bibliographic databases and grey literature were searched using systematic review methodology and the machine learning tool "Abstrackr."…

This paper examines the determinants of job-related training and workplace voice. Using data from a unique 2016 cross-national survey of Australian, British, Canadian and American employees, the paper contrasts two classic formulations in the literature; (1) the neoclassical/human capital approach which predicts that individual characteristics…

The purpose of this study is to use machine learning and exploratory data analysis to interrogate patterns of metrics from a national-level student survey. Analysis of over 1.8 million returns detected long-term stability of the predictors of student satisfaction, with survey items relating to course management and teaching being consistently most…

Covariates have been used in mixture IRT models to help explain why examinees are classed into different latent classes. Previous research has considered manifest variables as covariates in a mixture Rasch analysis for prediction of group membership. Latent covariates, however, are more likely to have higher correlations with the latent class…

Health warning labels (HWLs) on cigarette packs that use strong fear appeals may evoke defensive responses including acts of disparaging the warnings. Whether warning disparagement undermines HWL effectiveness remains unclear. We assessed correlates of one type of HWL disparagement and its association with subsequent cessation attempts.…

Introduction: This systematic literature review aims to (a) identify how the parenting stress was used in the empirical studies as an independent, outcome, moderator and mediator variable, (b) identify the predictors of parenting stress in parents of children with ASD, (c) identify how parenting stress relates with mental health, and (d) make…
