Abstract. This study examines world scientific production on renewable energy, sustainability and the environment on the basis of bibliometric indicators (scientific production, percentage variation of production, average cites per document, normalized impact, impact, etc.) for the period 2003–08. The analysis is made by country, by research institution, and by scientific journal, using the Scopus (Elsevier) database of scientific literature.

Abstract. A new size-independent indicator of scientific journal prestige, the SJR2 indicator, is proposed. This indicator takes into account not only the prestige of the citing scientific journal but also its closeness to the cited journal using the cosine of the angle between the vectors of the two journals’ cocitation profiles. To eliminate the size effect, the accumulated prestige is divided by the fraction of the journal's citable documents, thus eliminating the decreasing tendency of this type of indicator and giving meaning to the scores.

Abstract. This paper analyses relationships between university research performance and concentration of university research. Using the number of publications and their citation impact extracted from Scopus as proxies of research activity and research performance, respectively, it examines at a national level for 40 major countries the distribution of published research articles among its universities, and at an institutional level for a global set of 1500 universities the distribution of papers among 16 main subject fields.

Abstract. A bibliometric analysis of the 50 most frequently publishing Spanish universities shows large differences in the publication activity and citation impact among research disciplines within an institution. Gini Index is a useful measure of an institution’s disciplinary specialization and can roughly categorize universities in terms of general versus specialized. A study of the Spanish academic system reveals that assessment of a university’s research performance must take into account the disciplinary breadth of its publication activity and citation impact.

Abstract. Cuban scientific output at macro level has not been frequently studied in the literature on scientometrics. The current paper explores the different metric approaches to the Cuban scientific activity carried out by national and international authors.

Abstract. The creation of some kind of representations depicting the current state of Science (or scientograms) is an established and beaten track for many years now. However, if we are concerned with the automatic comparison, analysis and understanding of a set of scientograms, showing for instance the evolution of a scientific domain or a face-to-face comparison of several countries, the task is titanically complex as the amount of data to analyze becomes huge and complex.

Abstract. This manuscript reviews the literature on race and ethnicity in the political context. It discusses the most important scholarship on international migration, political mobilization, and the welfare state to date, to identify current gaps and emerging lines of inquiry. Future studies are needed to better understand the mobilization of immigrants by political parties, the role of local politics for a national electoral mobilization, and the relationship between local and national political areas for policy development.
