While several test concordance tables have been published, the research underpinning such tables has rarely been examined in detail. This study aimed to survey the publically available studies or documentation underpinning the test concordance tables of the providers of four major international language tests, all accepted by the Australian Department of Home Affairs for Australian visa purposes. To evaluate the concordance studies, we first identified the good practice principles in concordance research through a review of both the relevant literature and leading professional standards in the field of educational measurement and language assessment. Next, we reviewed the concordance studies against the identified good practice principles. Our findings revealed that the information supplied by test providers varied, with some making the full research papers available, whereas others providing little information about their underpinning research. None of the concordance studies fulfilled all the good practice principles. Based on the findings of this study, we offer recommendations for future concordance research in the field of language testing as well as suggestions for practice.

The medical field is facing a physician-scientist shortage, threatening future medical research and development. Medical institutions can contribute to developing physician-scientists by stimulating students' involvement in research. In this study, a medical undergraduate teaching module to develop research skills and encourage interest in research was held in Chongqing, China. Undergraduate medical students at Chongqing Medical University completed research skills training. Before and after the training, an online, anonymous, self-reported questionnaire was administered. The self-reported questionnaire investigated students' demographic characteristics, students' perception of attitudes toward conducting research, research skills (e.g., identifying and utilizing information, critical appraisal of literature, paper writing, and understanding of research), and feedback on scientific research training. The module was implemented with 25 students from July 2019 to October 2019, and 96.0% (N = 24) of participants responded to the questionnaire both prior to and after the training. In the evaluation of research skills, results showed that use of appropriate tools for research (Z = -3.340, p < 0.01), students' ability to undertake a focused literature search (Z = -3.40, p < 0.01), identifying and utilizing information (Z = -3.34, p < 0.01), and paper-writing skills (Z = -3.49, p < 0.01) were significantly improved after the undergraduates participated in the scientific research training. A qualitative analysis of the feedback showed that students found that the training helped to enhance their knowledge, improve their study scores, and motivate them to conduct research in the future. Early scientific research ability training strengthened the research skills of medical undergraduates and motivated them to pursue research.

The quality of a research study application sends a distinct signal to the institutional review board (IRB) about the skills, capacities, preparation, communication, experience, and resources of its authors. However, efforts to research and define IRB application quality have been insufficient. Inattention to the quality of an IRB application is consequential because the application precedes IRB review, and perceptions of quality between the two may be interrelated and interdependent. Without a clear understanding of quality, IRBs do not know how to define quality and researchers do not know how to achieve quality. This position has not been systematically studied to date, and future research could provide much-needed empirical validation. This paper lays the conceptual groundwork for future investigation into what constitutes quality in an IRB application. It includes a landscape review of multidisciplinary research on quality, as well as a discussion of quality frameworks analogous to research with human participants that exist in the published literature. It also examines the background and significance of federal research regulations, regulatory burdens, researchers' regulatory literacy, and the roles and responsibilities of IRB professionals within this ecosystem.

This paper is concerned with the process of selecting between the increasingly popular bi-factor model and the second-order factor model in measurement research. It is indicated that in certain settings widely used in empirical studies, the second-order model is nested in the bi-factor model and obtained from the latter after imposing appropriate parameter constraints. These restrictions can be directly tested within the framework of the latent variable modeling methodology employing widely circulated software. The outlined model selection procedure provides a readily applied means of choosing between the two models of growing interest to measurement scholars, and is illustrated using numerical data.

Although encompassing a variety of research approaches, qualitative research in music education shares the assumption that reality is socially constructed; it takes this construction to be based on the specific perspective of the individual human; and it considers epistemology and ontology to be different fields of study. The posthuman theory of agential realism, on the other hand, argues that the world is becoming through intra-actions; it decentres the individual humanist subject; and it studies onto-epistemology -- practices of knowing-in-being. Considering these fundamental differences, the quality criteria of qualitative research are not applicable to posthuman music education research. Nevertheless, posthuman research is concerned with the ethics of research and how to response-ably and ethically take part in the world's becoming. Thus, the emerging field of posthuman music education research must develop other ways of evaluating research beyond the quality criteria found in qualitative methodologies. This paper argues that diffraction -- both as a physical and musical phenomenon and as a philosophical concept -- might be a fruitful approach. By reading quality criteria diffractively through the agential realist concept of response-ability, it poses critical and creative questions, moving us towards evaluating the quality of posthuman music education research on its own terms.
