This paper addresses the problem of conveyor transfer station design in harsh operating conditions, aiming to identify and eliminate a failure phenomenon which interrupts aggregate supply. The analyzed transfer station is located in a Polish granite quarry. The study employs laser scanning and reverse engineering methods to map the existing transfer station and its geometry. Next, a discrete element method (DEM) model of granite aggregate has been created and used for simulating current operating conditions. The arch formation has been identified as the main reason for breakdowns. Alternative design solutions for transfer stations were tested in DEM simulations. The most uncomplicated design for manufacturing incorporated an impact plate, and a straight chute has been selected as the best solution. The study also involved identifying areas of the new station most exposed to wear phenomena. A new transfer point was implemented in the quarry and resolved the problem of blockages.

Background: Traditional research approaches are increasingly challenged in healthcare contexts as they produce abstract thinking rather than practical application. In this regard, action research is a growing area of popularity and interest, essentially because of its dual focus on theory and action. However, there is a need for action researchers not only to justify their research approach but also to demonstrate the quality of their empirical studies. Therefore, the authors set out to examine the current status of the quality of extant action research studies in healthcare to encourage improved scholarship in this area. The aim of this scoping review is to identify, explore and map the literature regarding the application of action research in either individual, group or organisational domains in any healthcare context. Methods: The systematic scoping review will search the literature within the databases of CINAHL, PubMed and ABI/Inform within the recent five-year period to investigate the scientific evidence of the quality of action research studies in healthcare contexts. The review will be guided by Arksey and O'Malley’s five mandatory steps, which have been updated and published online by the Joanna Briggs Institute. The review will follow the PRISMA-ScR framework guidelines to ensure the standard of the methodological and reporting approaches are exemplary. Conclusion: This paper outlines the protocol for an exploratory scoping review to systematically and comprehensively map out the evidence as to whether action research studies demonstrate explicitly how the essential factors of a comprehensive framework of action research are upheld. The review will summarise the evidence on the quality of current action research studies in healthcare. It is anticipated that the findings will inform future action researchers in designing studies to ensure the quality of the studies is upheld.

Race to the Top (RttT) reforms in States around the nation have initiated changes in the way teachers are evaluated and in the way new teachers are certified. The focus of this chapter is on sets of video-based action research studies aimed at analyzing and assessing classroom teaching performances and evaluating program effectiveness in a Professional Development School (PDS) partnership setting. The studies were part of a larger longitudinal research project begun in 1998. Authors present selected sets of studies as exemplars of a model research approach for continually changing and improving classroom teaching and the PDS's integrative pre-and inservice teacher education program. Readers are provided with the research and inquiry questions of the studies, key findings, and how findings were used to provide evidence of program effectiveness.

Action research is a relatively recent phenomenon in the field of English language teaching, having emerged in the literature predominantly since the late 1980s. In this article, I discuss the antecedents, definitions, processes, and purposes of action research in the field of English language teaching. Action research is also considered in relation to more established notions of basic and applied research. The current scope and nature of action research studies found in the literature are then analysed. The article concludes with a consideration of some of the challenges to the status of action research as a research methodology and the issues that will need to be addressed if action research by language teachers is to be sustainable.
