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
Isolated congenital absence of the nasal bones and its aesthetic surgical correction. Managing and case report
No full textA rare case of isolated congenital bone agenesis in a young woman referred to the authors for aesthetic correction of the dorsum profile is described. There are no descriptions of surgical treatment for this isolated facial defect in the literature. After a complete and accurate diagnostic study, a rhinoplasty was performed with a good result and without complications during a 2-year follow-up period. To explain this congenital malformation, several hypotheses were examined, such as bony resorption and embryologic bony development syndromes. This report describes the possibility of intervention in the case of nasal bone absence and shows how risks of structural instability can be avoided with an accurate preoperative study and a careful surgical approach
Use of local-regional flaps in facial reconstruction
No full textAim. Skin neoplasms are very common, with 700.000 new cases diagnosed annually: 77 % are basal cell carcinomas, 20 % squamous cell carcinomas and 3 % melanomas or rarer tumours. The incidence and prevalence of cutaneous neoplasms of the face are increasing and 86 % non-melanoma skin cancers are found in this area. Wide resection is mandatory and often results in large defects. Reconstructive procedures should respect functional and aesthetic units and sub-units of the face. Attention to unit and subunit anatomy facilitates adequate reconstruction with acceptable deformity. Methods. During a 10-year period 548 patients underwent reconstruction of the face for surgical defects having a diameter of 2.5 to 6.0 cm. Results. A single flap was employed in 356 patients and a combination of flap in 186 cases. Major complications occurred in 6 cases (1.1 %). Minor complications were observed in 15 patients (2.7%). Conclusions. The goals of skin cancer treatment are: complete lesion removal, preservation of normal tissue and function and optimal cosmesis. Although primary closure is the ideal method of reconstruction for small defects, flap closure provides a versatile and safe alternative In surgical defects closure, optimal aesthetic results are obtained if cosmetic units are preserved and, whenever possible, scars are placed in naturally occurring creases and folds
