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
Post-transplantlymphoproliferative disorder in the heart late after heterotopic transplantation:autopsy findings
No full textWe report the case of 52-year-old heart transplant recipient
positive for Epstein-Barr virus (EBV) and CD3 polymorphic
post-transplant lymphoproliferative disorder (PTLD). At age
39 years, the patient underwent heterotopic heart transplantation
for end-stage ischemic dilated cardiomyopathy in a setting
of irreversible pulmonary hypertension. He was asymptomatic
for 13 years after transplantation. During the intervening
period, he sustained an episode of rejection without
apparent sequelae. Immunosuppression consisted of cyclosporine,
azathioprine, and corticosteroids
