Abstract. This article analyzes the media effects on political knowledge after controlling for the most common factors (motivation, ability, and opportunities) in Spain. In addition, it explores whether the media contribute to increasing the existent knowledge gap in the Spanish polity. The results show that only one medium appears to have significant effects on knowledge: newspapers. An...

Abstract. Repowering of a wind farm is the process of replacing existing wind turbines with new turbines that either have a larger nameplate capacity or more efficiency, resulting in a net increase of the power generated. Although repowering brings, both, social and private benefits, there are also several obstacles to repowering which justify public support. The aim of this paper is to provide...

Abstract. This article proposes a new way to measure proportionality using aggregated threshold functions. Electoral systems can be summarised by a single value that shows the necessary share of the total vote to win either one seat or half of the seats in parliament. The article calculates aggregate threshold values for 142 different electoral systems that were used in 525 democratic elections...

Abstract. In 1989 the Spanish Government established an individual retrospective research evaluation system (RES) for public researchers. Policy makers have associated the establishment of this evaluation system with the significant increase in the volume of scientific publications attributed to Spain over the last decades. In a similar vein to the analyses of other country cases, some scholars...

Abstract. This article investigates whether the quality of higher education and, in particular, its research performance stimulate graduates' research-oriented careers. More specifically, exploiting a very rich data set on university graduates and the higher education institutions they attended, we empirically study whether graduates from universities and programs that display better academic...

Abstract. The aim of this paper is to develop a methodology based on the input–output approach which allows us to identify the structural and technological responsibility of manufacturing sectors in electricity consumption. Sectors with a high structural responsibility are those whose products are strongly demanded by other sectors and this leads to a high electricity consumption/production....

Abstract
Purpose
Although the role of enterprise in R&D is broadly acknowledged, few attempts have been made to gather data for analyzing the nature and scope of private sector collaboration. This study aims to deliver empirical results based on quantitative data to gain insight into the role of private enterprise as an indispensable actor in scientific development...

Abstract. Data on patent families is used in economic and statistical studies for many purposes, including the analysis of patenting strategies of applicants, the monitoring of the globalization of inventions and the comparison of the inventive performance and stock of technological knowledge of different countries. Most of these studies take family data as given, as a sort of black box, without...

Abstract. Category cocitation and its representation through social networks is proving to be a very adequate technique for the visualization and analysis of great scientific domains. Its combination with pathfinder networks using pruning values r = ∞ and q=n–1 makes manifest the essence of research in the domain represented, or what we might call the ‘most salient structure’. The...

Abstract. In this study, visual representations are created in order to analyze different aspects of scientific collaboration at the international level. The main objective is to identify the international facet of research by following the flow of knowledge as expressed by the number of scientific publications, and then establishes the main geographical axes of output, showing the...
