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...

Abstract. This paper studies the concept of ‘mutual aid’ developed by Kropotkin, which implies cooperation as a strategic choice. We study this concept in a sequential prisoner’s dilemma in a non-cooperative framework and in an indirect evolution framework (with complete and incomplete information). We systematically compare this game with one that models Kant’s moral. In the non-cooperative...

Abstract. Based on the data from survey responses and publications of 1583 academic scientists in Spain, this paper examines the relationship between scientific performance and reward, considering tenure and permanent positions as key academic rewards in early phases of academic career and focusing especially on the mediating effect of mobile versus stable career paths. Although widely practiced...

Abstract. Using the Scopus dataset (1996–2007) a grand matrix of aggregated journal-journal citations was constructed. This matrix can be compared in terms of the network structures with the matrix contained in the Journal Citation Reports (JCR) of the Institute of Scientific Information (ISI). Because the Scopus database contains a larger number of journals and covers...

Abstract. This paper presents an optimal control model to analyze reforestations with two different species, including commercial values, carbon sequestration and biodiversity or scenic values. We discuss the implications of partial or total internalization of environmental values, showing that internalizing only carbon sequestration may have negative impacts on biodiversity-scenic values. To...

Abstract .The objective of this paper is to study in depth the perspective of the individual in rural geographic studies, specifically relationships between the position of the individual in the community and the physical space they inhabit. The focus of the study is individuals living alone in Spain, in the middle of the countryside in depopulated nuclei, with space but almost without a...
