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
Gas tamponade and cyclocryotherapy of a chronic cyclodialysis cleft.
No full textAims: To describe a minimally invasive technique to treat a chronic large cyclodialysis cleft that had failed to respond to medical therapy. Methods: A 51-year-old man with a history of blunt trauma developed a unilateral chronic ocular hypotony. He was treated with topical atropine 1% for 3 months. 12 months later, the patient was referred to our glaucoma service for evaluation and treatment of persistent hypotony. Ultrasound biomicroscopy (UBM) displayed a cyclodialysis cleft extending from the 6 to 12 o'clock positions. B-scan echography revealed a peripheral choroidal effusion. A single bubble of 20% sulfur hexafluoride was injected into the vitreous cavity and transconjunctival cyclocryotherapy was performed. Results: After gas absorption, intraocular pressure increased to 12 mm Hg and became steady during the follow-up. B-scan echography showed the disappearance of choroidal effusion, and UBM displayed a complete closure of the cyclodialysis cleft from the 6 to 8:30 o'clock positions and from the 9:30 to 12 o'clock positions. A small cleft extending from the 8:30 to the 9:30 positions remained after the treatment, but the distance between the scleral spur and the ciliary boby decreased, and the cleft was limited at the back due to the scar formation. Conclusion: Gas tamponade with cyclocryotherapy represents a minimally invasive technique that is worth considering for patients with cyclodialysis clefts associated with a shallow anterior chamber and that had failed to respond to medical therapy. This technique should be useful in cases of cyclodialysis clefts that are not amenable to treatment with more conservative efforts
