Abstract. The limitations of citation-based indicators include a lack of coverage, no normalization with respect to the length of reference lists (with a potential bias in favour of reviews), and different citation habits. As a consequence, the distributions of the indicators are not comparable across different disciplines. Here we show that the most popular journal citation indicators used in...

Abstract. Considerable research shows the economy matters for voters. But that view has come under attack, with revisionists arguing that it matters little. This dissenting view fits the Spanish case well, where reigning research finds virtually no economic voting exists. We argue against the revisionist view, suggesting that conclusion stems largely from methodological limitations in its...

Abstract. The analysis of university-industry cooperation (UIC) rarely considers the geographic implications of its promotion. We hypothesise that UIC may lead to a cumulative advantage of already good performers. The 6th EU R&D Framework Programme is a useful source to verify this hypothesis because of its a priori neutrality regarding UIC. Using original data on the funding...

Abstract. Following environmental and economic motivations, most countries in the world are confronting the challenge of reducing both their dependence on fossil fuels and their greenhouse gas (GHG) emissions. The promotion of renewable energy sources (RES) contributes to these two goals while simultaneously bringing economic opportunities in less industrialized areas and positioning national...

Abstract. The aim of this paper is to identify those sectors that contribute most to electricity consumption in Spain, using a methodology based on input–output tables, and to derive some recommendations aimed at increasing energy efficiency in those sectors. This input–output approach is complemented with a sector-focused study in which the availability of electricity-efficient technologies per...

Abstract. This article explores the concentration in the global plant molecular life science research output. In the past 15 years, especially the share of articles which refer to the model organism A. thaliana has increased rapidly. Citation analyses show an even greater rise in the importance of this organism. Attempts are discussed to come to a scientometric definition of model...

Abstract. This analysis measures the net benefit that a landowner could obtain from changing current dry-land cereal fields into Stone pine plantations in Portillo and Viana (Valladolid, Spain). We apply cost–benefit analysis techniques to estimate the present value of Stone pine afforestation net benefit by considering an infinite series of forestry rotations. We simulate three Stone pine...

Abstract. The production and consumption of electricity is a major source of CO₂ emissions in Europe and elsewhere. In turn, the manufacturing sectors are significant end-users of electricity. In contrast to most papers in the literature, which focus on the supply-side, this study tackles the demand-side of electricity. An input–output approach combined with a sensitivity analysis has...

Abstract. The Ranking Web of World Repositories (http://repositories.webometrics.info) is introduced. The objective is to promote Open access initiatives (OAI) supporting the use of repositories for scientific evaluation purposes. A set of metrics based on web presence, impact and usage is discussed. The Ranking is built on indicators obtained...

Abstract. The present paper proposes a method for detecting, identifying and visualizing research groups. The data used refer to nine Carlos III University of Madrid departments, while the findings for the Communication Technologies Department illustrate the method. Structural analysis was used to generate co-authorship networks. Research groups were identified on the basis of factorial analysis...
