There has been considerable recent interest in methods of determining sample size for qualitative research a priori, rather than through an adaptive approach such as saturation. Extending previous literature in this area, we identify four distinct approaches to determining sample size in this way: rules of thumb, conceptual models, numerical…

We present an aggregation scheme that increases power in randomized controlled trials and quasi-experiments when the intervention possesses a robust and well-articulated theory of change. Intervention studies using longitudinal data often include multiple observations on individuals, some of which may be more likely to manifest a treatment effect…

Purpose: This study investigates the motivations, contributions, and challenges faced by international researchers employed at Japanese companies. It utilizes Tomlinson's Graduate Capital Model to gain insight into their experiences. Design/Approach/Methods: This study employs Tomlinson's Graduate Capital Model as an analytical framework to…

Swales' (1990) Creating a Research Space (CARS) model has spawned a large number of studies focusing on investigations of research article introductions (RAIs), and the reports have given meaningful contributions to guide novice and non-native authors in writing English RAIs. However, the investigation of authors' research gap strategies in RAIs…

Pupil Premium funding has been provided to schools in England since 2011, to help overcome socio-economic segregation between schools, and reduce the poverty attainment gap. Yet there is little evidence such an approach is effective. Some important stakeholders are considering whether Pupil Premium should stop or be re-routed. It is therefore…

This study identified the main explanatory factors of dropout in higher education in Rivera, Uruguay, and showed that the limitations and methodological implications related to the polysemic nature of the concept of dropout should be addressed by studies on this subject. Through a systematic search of the international scientific literature, the…

Most quantitative studies in the social sciences suffer from missing data. However, despite the large availability of documents and software to treat such data, it appears that many social scientists do not apply good practices regarding missing data. We analyzed quantitative papers published in 2017 in six top-level social science journals.…

This theoretical essay critically examines the impact of Coladarci's 2007 article, "Improving the Yield of Rural Education Research: An Editor's Swan Song," which he composed at the conclusion of his tenure as editor of the Journal of Research in Rural Education. Using boundary theory and "awayness" as a metaphor for…

The research cited in this article provides a comprehensive summary of the risk factors for LGBTQ youth, which represents a strength of this body of work. It is important for mental health professionals to be aware of the risk factors for this diverse population in order to better understand the experiences of LGBTQ youth and how these experiences…

Background: Research integrity has gained attention in the general public as well as in the research community. We wanted to investigate knowledge, attitudes, and practices amongst researchers that have recently finished their PhD and compare this to their responses during their PhD fellowship. In particular, we wanted to investigate whether their…

The movement toward open-science is multifaceted with the general goal to promote both better scientific practices and greater access to scientific information. One aspect of the open-science framework is the recommended use of registered reports replacing the legacy model that dictates research manuscripts are submitted for initial review only…

The authors are grateful for this opportunity to respond to Robbins's and Turner's review of "Functional Family Therapy (FFT) for Behavior Disordered Youth Aged 10-18: An Overview of Reviews" (Weisman & Montgomery, 2018). It may be helpful to ensure that a few key points have been clarified to enable this process. In their paper,…

In response to concerns about the credibility of many published research findings, open science reforms such as preregistration, data sharing, and alternative forms of publication are being increasingly adopted across scientific communities. Although journals on giftedness and advanced academic research have already implemented several of these…

Identity research in mathematics education has become increasingly prominent over the past two decades. In the last few years, there have been several reviews of identity literature in the field of mathematics education generally, or specifically focused on mathematics learner identities or mathematics teacher identity. We begin our paper by…

Researchers are challenged to provide opportunities for people with intellectual disabilities (IDs) and their families to become participants in research. This article explores the processes and procedures involved in conducting a mixed-methods study. The preparation for the study is described and explained. Recruitment is examined by describing…
