Plant Genetic Resources Protection in the Mediterranean Basin: the Case of Sardinian Forage Species
No full textA Regional Bill on “Protection of Sardinian Local plant genetic resources” and regulations regarding collection activities for scientific, economic and commercial purposes” has been worked out by the Authors of this paper and submitted to the Sardinian Regional Parliament in April 1999. Main objectives of the Regional Bill are the regulations and rationalization of collection activities of autochthonous plant genetic materials for economic and/or commercial purposes without constraints for the rights and interests of local populations and workers that take benefit from such resources. By means of this paper, we intend to bring the Sardinian Regional Bill to knowledge of all people involved in local germplasm protection and of public opinion as a whole, its set of rules could in fact be useful at the Mediterranean level

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
