This paper puts forward a research agenda in the area of explicit and implicit knowledge and learning of second or additional languages. Based on a brief overview of reliable findings as well as open questions in the field, three agenda items are highlighted. First, valid and reliable measures of explicit and, in particular, implicit knowledge and…

This paper investigates the potential of Ubuntu philosophy for decolonising Participatory Research (PR) in the Global South, addressing power imbalances and research process challenges. Despite PR's focus on community involvement, it can perpetuate practices contradicting its principles, hence the rise of 'decolonising research' for fair,…

Educational research outcomes frequently rely on an assumption that measurement metrics have interval-level properties. While most investigators know enough to be suspicious of interval-level claims, and in some cases even question their findings given such doubts, there is a lack of understanding regarding the measurement conditions that create…

Agent-based models (ABMs) often rely on psychometric constructs such as 'opinions', 'stubbornness', 'happiness', etc. The measurement process for these constructs is quite different from the one used in physics as there is no standardized unit of measurement for opinion or happiness. Consequently, measurements are usually affected by 'psychometric…

In causal mediation studies that decompose an average treatment effect into indirect and direct effects, examples of post-treatment confounding are abundant. In the presence of treatment-by-mediator interactions, past research has generally considered it infeasible to adjust for a post-treatment confounder of the mediator-outcome relationship due…

This case study is based on research undertaken in 2021 that was prompted by the disruption of COVID-19 in higher education institutions and the subsequent pivot to online learning. The research explored a cross-institutional change project, which was supported and enabled by an agile and matrix-led working environment. The Transformation Academy…

This article concerns the ways in which authors from various fields conceptualise the ethical issues arising in the conduct of research. We reviewed critically and systematically the literature concerning the ethics of conducting research in order to engage in a reflection about the vocabulary and conceptual categories used in the publications…

The recent commentary by Beaujean and Farmer (2020) on the original paper by Dixon et al. (2019) serves a cautionary tale of selective p-values, the law of small N sizes, and the type-II error. We believe these authors have crafted a somewhat questionable argument in which only 57% of the original Dixon et al. data were re-analyzed, based on a…

In recent decades, there has been an explosion of research into the crossmodal influence of olfactory cues on multisensory person perception. Numerous peer-reviewed studies have documented that a variety of olfactory stimuli, from ambient malodours through to fine fragrances, and even a range of chemosensory body odours can influence everything…

Address-based sampling (ABS) refers to the use a list of addresses derived from the U.S. Postal Service's Computerized Delivery Sequence File as a sampling frame. While most residential addresses are included on an ABS frame, it still suffers from undercoverage. Undercoverage is problematic only if the uncovered units have different attributes…

The population discrepancy between unstandardized and standardized reliability of homogeneous multicomponent measuring instruments is examined. Within a latent variable modeling framework, it is shown that the standardized reliability coefficient for unidimensional scales can be markedly higher than the corresponding unstandardized reliability…

Literature inclusion and exclusion (E/I) criteria are a fundamental selection methodology in different applications. Mainly, the E/I criteria are identified and chosen with respect to the question for which the manuscript itself is produced, thus allowing the selection of the literature. This procedure is not always related to the economic…

The attitude of teachers towards inclusive education is a key issue for the success of inclusive education. Many studies have been designed to assess teachers' attitudes, but none have looked at the bias caused by teachers' non-response to questionnaires on their attitudes. Non-response biases are difficult to identify because it is impossible to…

Collaborative projects designed to generate research evidence involve knowledge exchange (KE) which hinges on the expectations and practices within the collaborating organisations. Existing literature about academic-police collaborations, and why they break down, has largely focused on different knowledge agendas, research timeframes and…

Asymmetric Likert-type items in research studies can present several challenges in data analysis, particularly concerning missing data. These items are often characterized by a skewed scaling, where either there is no neutral response option or an unequal number of possible positive and negative responses. The use of conventional techniques, such…
