This article explores the models and frameworks developed on "research impact'. We aim to provide a comprehensive overview of related literature through scoping study method. The present research investigates the nature, objectives, approaches, and other main attributes of the research impact models. It examines to analyze and classify models…

To keep up with rapid evolutions in technical and scientific developments, countries must create competitive dynamics that enable key actors to generate high-tech projects, boosting both a country's productivity and economic development.

They are led to examine a distinction that the Institute of Education Sciences (IES) makes between "confirmatory"…

The proportional odds (PO) model, which is also called cumulative odds model (Agresti, 1996, 2002 ; Armstrong & Sloan, 1989; Long, 1997, Long & Freese, 2006; McCullagh, 1980; McCullagh & Nelder, 1989; Powers & Xie, 2000; O'Connell, 2006), is one of the most commonly used models for the analysis of ordinal categorical data and comes from the class…
