Liver transplantation in Italy: current status. Study Group on Liver Transplantation of the Italian Association for the Study of the Liver (A.I.S.F.)
No full textThe first liver transplant in Italy was performed in 1982. With the improvement in results, the number of patients followed, in recent years, has substantially increased in all centres. In parallel, the indications for liver transplantation have expanded and have raised the need for more organized structures where patients can be referred for evaluation and transplantation. Indications and contraindications to liver transplantation in Italy, the role of retransplantation, paediatric liver transplantation, waiting list management, liver transplantation outside Italy and the new Italian laws on organ donation are discussed. The multidisciplinary Study Group on Liver Transplantation of the Italian Association for the Study of the Liver (AISF) has collected information from all the Italian centres to ascertain the degree of consistency in their methods
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
