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
Monolateral tubulovasostomy. Report of four cases
No full textAfter conventional vasoepididymostony, the epididymal lumen may become occluded or obstructed, resulting in recurring azoospermia. Recently, two-layer direct anastomosis has been advocated on the basis of experimental models of tubulovasostomy performed in rats. Monolateral tubulovasostomy was performed in four cases under 16-40 times magnification. Nylon or 11/0 Vycril was used as suture material for the internal layer of the anastomosis, and 10/0 Ethilon was used for the external layer. After three and six months, semen samples were evaluated for sperm count and motility. The presence of spermatozoa in all the samples confirmed 100% patency of the duct. Three patients had a number of spermatozoa compatible with fertility, and one pregnancy occurred
