Abstract. In Mediterranean silvopastoral ecosystems, grazing continues to be a key economic practice that shapes forest, woodland, shrubland and grassland and remains a primary feed source for livestock breeding. However, conventional national accounting statistics do not provide information on livestock grazing leases and environmental income. The main goals of this study were to apply the residual value method for measuring livestock grazing forage consumption and its private environmental price according to the predominant vegetation at the farm scale.

Abstract

Background
In the greater framework of the essential functions of Public Health, our focus is on a systematic, objective, external evaluation of Latin American scientific output, to compare its publications in the area of Public Health with those of other major geographic zones. We aim to describe the regional distribution of output in Public Health, and the level of visibility and specialization, for Latin America; it can then be characterized and compared in the international context.

Abstract. Drawing on social choice theory we derive a rationale in which each reviewer is asked to provide his or her second, third, and fourth choice in addition to his/her first choice recommendation regarding the acceptance/revision/rejection of a given manuscript. All reviewers’ hierarchies of alternatives are collected and combined such that an overall ranking can be computed.

Abstract

Purpose
The web application presented in this paper allows for an analysis to reveal centres of excellence in different fields worldwide using publication and citation data. Only specific aspects of institutional performance are taken into account and other aspects such as teaching performance or societal impact of research are not considered. The purpose of this paper is to address these issues.

Abstract. University rankings generally present users with the problem of placing the results given for an institution in context. Only a comparison with the performance of all other institutions makes it possible to say exactly where an institution stands.
