In this commentary, the author focuses on the use of design elements for increasing the severity of causal mediation tests. The estimation of causal mediation effects from observational data rests on rather stringent assumptions. In introducing and exemplifying ratio-of-mediator-probability weighting (RMPW), Hong and Nomi (henceforth HN) make…

In this article, school sector differences in tertiary entrance performance were examined using longitudinal data from the state of Victoria in Australia for 2011. Analysis of students' Tertiary Entrance Aggregate, from which the Australian Tertiary Admission Rank is derived, revealed non-trivial effect sizes of sector on performance. Results…

There is currently a considerable body of research suggesting that parental involvement is linked to young people's attainment at school. It is also generally agreed that a number of factors such as parental background, attention, warmth and parenting style are associated with children's later life outcomes. However, although widely assumed on the…

This article reports on resistance in primary schools, more specific grade five learners as perceived by teachers. A qualitative phenomenological interpretative approach was followed utilising focus group discussions and individual interviews. Participants included 14 teachers, purposefully selected from three private and three public schools in…

Previous research has shown that individuals with autism spectrum disorder (ASD) had difficulty integrating narrative information coherently. The majority of these studies focused on people narrating in English; however, little is known about the narrative abilities of Mandarin-speaking individuals with ASD. This study investigates the ability of…

Finance threshold concepts are the essential conceptual knowledge that underpin well-developed financial capabilities and are central to the mastery of finance. In this paper we investigate threshold concepts in finance from the point of view of students, by establishing the extent to which students are aware of threshold concepts identified by…

The following review of literature illuminates self-advocacy from a North American transformational learning perspective via meaningful impacts, which arise for adults with developmental disabilities, as well as various communities and their members. For adults with developmental disabilities, increased leadership capabilities and the evolution of…

The purpose of the present study was to investigate the application of the Model of Reciprocal Causation (MRC) in examining the relationship between student personality (personal factors), student-perceived teacher interpersonal behavior (environment), and Mathematics achievement (behavior), with the simultaneous investigation of mediating effects…

A valuable extension of the single-rating regression discontinuity design (RDD) is a multiple-rating RDD (MRRDD). To date, four main methods have been used to estimate average treatment effects at the multiple treatment frontiers of an MRRDD: the "surface" method, the "frontier" method, the "binding-score" method, and…

There are usually limited user evaluation of resources on a recommender system, which caused an extremely sparse user rating matrix, and this greatly reduce the accuracy of personalized recommendation, especially for new users or new items. This paper presents a recommendation method based on rating prediction using causal association rules.…

Young children spend a large portion of their time pretending about non-real situations. Why? We answer this question by using the framework of Bayesian causal models to argue that pretending and counterfactual reasoning engage the same component cognitive abilities: disengaging with current reality, making inferences about an alternative…

The contiguity effect refers to the tendency to recall an item from nearby study positions of the just recalled item. Causal models of contiguity suggest that recalled items are used as probes, causing a change in the memory state for subsequent recall attempts. Noncausal models of the contiguity effect assume the memory state is unaffected by…

The purpose of this study was to examine what caused IT projects to fail at a high rate in the pharmaceutical industry. IT projects failures delayed development of new drugs that can help save lives. It was imperative to evaluate what caused project failures because the collateral damage was delay in drug development. This qualitative…

The increasing availability of data from multi-site randomized trials provides a potential opportunity to use instrumental variables methods to study the effects of multiple hypothesized mediators of the effect of a treatment. We derive nine assumptions needed to identify the effects of multiple mediators when using site-by-treatment interactions…

Problem Statement: A literature analysis revealed that contact disturbances, self-esteem and life satisfaction have been examined in different studies separately. In particular, the researchers observed that the studies conducted on Gestalt contact disturbances are limited in number. In this study, the variables of contact disturbances,…
