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

No full textThe platysma myocutaneous flap (PMF) is a common reconstructive option for defects in the head and neck region. Its applications have
expanded from the reconstruction of intraoral defects to include laryngo-pharyngeal, lip, and cheek defects. The platysma flap can be superiorly,
posteriorly, or inferiorly-based. The superiorly-based flap has a robust arterial blood supply but less efficient venous drainage, whereas the
opposite is the case with the posteriorly-based flap.
We present our results of using a superiorly based PMF flap for reconstruction of defects in the parotid, auricular/mastoid, and cheek
regions after resection for squamous cell carcinoma. Of 11 patients, eight had no postoperative complications. The remaining three developed
venous congestion of their flaps, in two of whom it led to secondary epidermolysis and limited skin loss. The venous congestion resolved
with conservative management, and all flaps remained viable.
The PMF flap is an alternative to more complex reconstructive options for skin defects of the auricular, parotid, and cheek regions, and
gives a satisfactory cosmetic result
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
