“…The contribution of countries or groups of countries to journals or conferences has been explored since 1980s (Schubert, Glänzel, & Braun, 1989;Braun, Glänzel, & Schubert, 1985;Schubert, Zsindely, & Braun, 1983). Some studies have investigated country distributions of publications in a few high-impact journals; most have been carried out on specific fields of science and reported that most papers in high-quality journals come from researchers in the U.S. and U.K., with few from developing countries (Elliott, Greenaway, & Sapsford, 1998;Black & Davies, 1999;Boldt, Maleck & Koetter, 1999;Carnegie & Potter, 2000;Patel & Sumathipala, 2001;Jones & Roberts, 2005;Mahawar, Malviya, & Kumar, 2006;Cheung, 2009). Indeed, the chance of being accepted in an American journal is lower for submissions from countries other than the U.S. (Elster and Chen, 1994) and also the acceptance rate of papers from highincome countries is about five times greater than that of papers from low-and middle-income countries (Singh, 2006).…”
