Abstract. A graphical interface designed to access the bibliometric indicators database of the SCImago Journal & Country Rank portal (http://scimagojr.com/shapeofscience) is described. The map was generated from the relational matrix based on the citation, co-citation, and bibliographic coupling formed by the nearly 20,000 publications (...

Abstract. Drawing on social choice theory we derive a rationale in which each reviewer is asked to provide his or her second, third, and fourth choice in addition to his/her first choice recommendation regarding the acceptance/revision/rejection of a given manuscript. All reviewers’ hierarchies of alternatives are collected and combined such that an overall ranking can be computed. Consequently,...
Resumen. Se analiza la investigación española en células madre en el Science Citation Index (SCI) entre 1997 y 2010 con una división temporal en tres sub-períodos, mediante técnicas de visualización basadas en redes sociales. Se han utilizado los descriptores KeyWords Plus (KW+) como unidad de análisis, su coocurrencia como unidad de medida, y Pajek...

Abstract. This paper describes the results of a multi-level network analysis of web-citations among the 1,000 universities with the greatest presence on the world wide web. Using data from January 2011, it describes the web-citation network of the world’s universities and ascertains the antecedent factors that determine its structure. At the university level, the network is composed of ten groups...
Abstract. The aim of this paper is to identify the factors that drive support levels for wind on-shore electricity in the Member States of the European Union (EU) with the help of econometric techniques. The econometric analysis is based on cross-section linear regressions with ordinary least squares. Four alternative specifications of the model have been estimated. The estimates comply with the...
Abstract. Subject classification arises as an important topic for bibliometrics and scientometrics, searching to develop reliable and consistent tools and outputs. Such objectives also call for a well delimited underlying subject classification scheme that adequately reflects scientific fields. Within the broad ensemble of classification techniques, clustering analysis is one of the...
Abstract. University rankings generally present users with the problem of placing the results given for an institution in context. Only a comparison with the performance of all other institutions makes it possible to say exactly where an institution stands. In order to interpret the results of the SCImago Institutions Ranking (based on Scopus data) and the Leiden Ranking (based on Web of Science...

The lack of an integrated information policy for scientific activity evaluation has led to a wide range of information products and services that are used for such purposes, although they were not originally designed for that. While it is true that these tools have limitations and deficiencies, and in several cases are technologically and methodologically obsolete, possibly the biggest...
