[Radial forearm free cutaneous flap. Evaluation of the level of damage to the donor site].
No full textAfter more than a decade of experiences, the radial forearm fasciocutaneous free flap has proven to be a well standardized surgical technique, widely used for its easy application and versatility. The review of the literature shows that most of the contraindications to the use of this flap concern mainly the donor site morbidity. Aim of this work is to evaluate the complications of this surgical technique, to study the functional impairment and the scars secondary to the harvesting of the flap, in order to point out which techniques can contribute to their reduction. Seventeen patients submitted consecutively to oral cavity reconstruction using a radial forearm flap, whose donor site has been reconstructed with a full-thickness skin graft have been studied. The postoperative complications have been examined, the functional and aesthetic alteration at the donor site analyzed, with a medium follow-up of 17.5 months. The study of this series has pointed out not relevant early and middle term postoperative complications, no significant hand or finger motility and sensorial deficiencies associated with a percentage of full aesthetic and functional satisfaction of patients for this treatment higher than 80%. On the basis of personal clinical experience, even if on a small series of cases, the conclusion is drawn that the functional and aesthetic outcomes depend significantly on the surgical techniques used to harvest the flap and to cover the donor site
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
