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
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
Does a double long saphenous vein exist?
No full textBackground: The incidence of reduplication of the long saphenous vein (LSV) reported in the literature is highly variable, perhaps due to the lack of a clear definition. Objective: To use ultrasonography to re-evaluate the incidence of LSV reduplication in healthy subjects and patients with varicose veins on the basis of a new definition of this anatomical aspect. Methods: The presence of two parallel superficial venous channels in the lower limb was sought in a series of 610 duplex ultrasound examinations. The LSV was identified, by the 'eye' sign, running deeply in the hypodermis, closely ensheathed by two hyperechogenic laminae (the saphenous compartment). Tributary veins were identified by their more superficial course, lying outside the compartment. True LSV reduplication was considered to be present when two venous channels were present within the saphenous compartment. Results: True reduplication of the LSV is extremely rare (1%) and only affects a segment of vein. Large tributaries running parallel to the LSV do not comprise true reduplication, but may act as a 'functional double vein': Better understanding of the anatomy of the LSV may Improve operative treatment for varicose veins and improve the use of saphenous veins as arterial grafts
