Recovery of infraorbital nerve function after zygomaticomaxillary cheek pedicled flap
No full textThe zygomaticomaxillary cheek pedicled flap (ZMCF) involves the intentional section of the infraorbital nerve to reflect the flap laterally in order to give access to the rhinopharynx, clivus and upper cervical spine. The aim of this trial was to examine the recovery of sensation of the infraorbital nerve, both quantitatively (touch sensation, localisation test, two-point discrimination) and qualitatively (sharp/blunt test, temperature sensation, pain sensitivity, dental sensitivity) in 7 patients, at least 12 months after surgery. In each patient, four cutaneous areas (lower eyelid, nose ala, upper lip, cheek) and the upper vestibulum were tested. Results of each test in all the examined areas were evaluated and compared with the data obtained on the nonoperated side (control side). Results of neurosensory tests indicated good recovery of sensation with little difference in comparison with the control side, showing that the functional consequence of ZMCF should actually be considered only as a transitory event

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
Gap arthroplasty and distraction osteogenesis for simultaneous correction of the mandibular deformity in childhood TMJ post-traumatic ankylosis : a case report
No full textTemporomandibular joint (TMJ) ankylosis has a variety of causes, with trauma and infection being the commonest in the paediatric age group. More often than infections, post-traumatic condylar fracture can go undiagnosed in this age group and lead to post-traumatic TMJ ankylosis. We report a case of a 12-year-old boy presented with a face deformity and mouth opening limitation due to post-traumatic ankylosis of the left temporomandibular joint (TMJ). We obtained a satisfactory improvement in mouth opening and a good aesthetic balance of the face. The postoperative orthopantomogram showed that the neocondyle generated by osteodistraction of the mandibular ramus allowed us to reproduce the posterior height of the face. At the 2-year follow-up, we were convinced of the great benefits of this technique on the residual growth potential
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
