Abstract

Bibliometric indicators of production and impact of e-learning research are analyzed to know the contribution of countries and institutions in the scientific development of this subject and to strengthen its characterization as knowledge domain. We extracted bibliometric indicators from 39,244 documents indexed in Scopus and SCImago  Institutional  Rankings, and generated maps of production and collaboration networks and graphics about the impact of e-learning research in countries and institutions. The results of this combined analysis showed that at country level the United States produce most of the works and generated the greatest international collaboration. At institutional level, the University of Hong Kong is the most productive and National Taiwan University of Science and Technology is the one with the greatest collaboration. In addition, the analysis showed that Taiwan ranks first in productivity and impact, which is why we linked these results to a brief analysis of its national policies. This study presents a new method to analyze both emerging and established knowledge domains.

Abstract

A quantitative analysis of the scientific production of Ecuador in the Andean context is provided for 2000-2013, using data provided by the SCImago journal & country rank (SJR). We identified the indicators of absolute production and growth rate, and used three indicators to evaluate visibility: absolute citation, cites per document and international collaboration. We concluded that 1) Ecuador enjoyed positive growth in scientific production during the study period, except in 2010 and 2011; 2) it rebounded at the end of the period analyzed; 3) half of the production was in the areas of agriculture and medicine, which therefore appeared as the main areas of national scientific development; and 4) the most productive area, agriculture, was also the most cited.

Abstract

Scientific research in the communication field has experienced great growth in recent years. Recent technological changes, as well as the emergence of Web 2.0 and 3.0 and new forms of communication, such as social networks, have led to new and varied studies in the discipline. This paper analyzes the scientific production of the 27 countries with the greatest scientific production in the communication field in the period from 2003 to 2018. The results indicate that: the most productive countries are the USA, UK, and Spain; there is less international collaboration than in other disciplines, but there is a network of European collaboration that is quite dense and has great impact, and another network in Pacific countries (Asia + Oceania), albeit with lower density and impact.
