Abstract. A methodology is developed which allows us to measure the responsibility of the productive structure of an economic system with respect to the consumption and generation of electricity within an input–output framework. We propose a technical indicator of technology responsibility in electricity consumption based on the assessment of technical coefficients.

Abstract. The web is not only the main scholarly communication tool but also an important source of additional information about the individual researchers, their scientific and academic activities and their formally and informally published results. The aim of this study is to investigate whether successful scientists use their personal websites to disseminate their work and career details and to know which specific contents are provided on those sites, in order to check if they could be used in research evaluation.

Abstract. Highly skilled return migrants contribute to the establishment of ties between the home and host systems. This paper studies how the professional ties, which Argentinean researchers built up during the time spent in foreign research systems, influence their collaboration patterns and their research outputs upon return. It confirms the expectation that having foreign work experience helps to explain the propensity to co-publish internationally and it also shows that researchers collaborate to a higher degree with their former host system.

Abstract. Exposure of livestock grazing to forage productivity variation and to market fluctuations affects the risk of investment and returns from cow-calf operations, but little work has been done to empirically compare these returns to the returns that would be demanded by financial markets from assets with similar risk and return characteristics. This study uses historical forage production data from three rangeland locations in California, and cattle and hay prices, to simulate financial statements for three hypothetical cow-calf producers in the period 1988–2007.

Abstract. Economic voting studies remain contentious in Spain. The notion is widely-held that there is no economic vote in that country, due to the pervasive and effacing influences of left-right ideology. Still, a growing number of investigations show a significant impact of economic evaluation on the vote choice in Spanish national elections. At least one possible exception here is the 2008 election, where the question has received no systematic treatment. In this study, we explore the impact of economic voting in that contest.
