Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Aesthetic role of the surgically rebuilt inframammary fold for implant-based breast reconstruction after mastectomy
The inframammary fold (IMF) represents one of the most important anatomic landmarks in defining a woman's breast ptosis and inferior quadrant shape. Therefore it is important to preserve it, if this is oncologically safe, at the time of excisional surgery. If it is sacrificed, dislocated cranially or caudally, or there is a thick panniculus adiposus with a poor definition of the fold, it is necessary to recreate it. We present our experience in the reconstruction of the IMF in patients suffering from post-oncologic mastectomy, reconstructed with silicone implants. From January 2000 to May 2004 at the Plastic Surgery Department of the University of Turin, 74 reconstructions of the IMF were performed through Nava's technique, partially modified by us. We believe that IMF reconstruction, through fixation of cutis, subcutis and fascia superficialis to VI rib, along with capsulectomy of periprotesic pocket inferior quadrants, is a milestone for achieving, in selected cases, a good aesthetic result in terms of shape, ptosis and projection of inferior pole. The comparison between patients' opinions (obtained through questionnaires) and surgeon's, at 1 year after the reconstruction, shows that both are satisfied with the achieved outcome in terms of shape, projection, symmetry, ptosis and IMF definition. Another comparison was made between cases of fold preservation and cases of fold reconstruction, with a remarkable similarity of aesthetic satisfaction. The technique proposed here appears to be the current method of choice for IMF reconstruction in all cases where it is necessary to recreate or redefine it. © 2006 British Association of Plastic, Reconstructive and Aesthetic Surgeons
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
The authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
