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
Tracheobronchial obstruction: Follow-up study of 100 children treated with airway stenting
No full textOBJECTIVE: We described a cohort of 100 children with a wide variety of airway obstruction who underwent stent positioning in the last 7 years. The study examined the outcomes of this treatment in the largest series of paediatric patients reported in the literature with special concern over safety and clinical effectiveness. METHODS: We performed a retrospective analysis of 100 consecutive paediatric patients who underwent stent insertions between January 2005 and May 2012. Statistical analysis was performed and exact likelihood was used. RESULTS: A total of 235 stents were placed for severe airway obstruction. One hundred and twelve silicone stents (cylinder, hourglass or Y-shaped), 120 metallic stents (covered Nitinol stents, expandable coronary and vascular stents) and 3 biodegradable polydioxanone (PDS) stents were used. Eighty patients presented clinical improvement after stent insertion, 17 were weaned off mechanical ventilation and 3 showed no significant clinical improvement [95% confidence interval (CI) 0.1-8.0%]. Complications were different according to stent type. In our cohort, no fatal stent-related complications have been observed. At follow-up (median 41.4 months, range 1.1-145.4) complete resolution was registered for 60 patients (66%; 95% CI 55-76%), 17 are still under treatment, 9 were lost to follow-up, 8 underwent surgery and 6 died of causes not stent related. CONCLUSION: Airway stenting represents a conservative treatment before more invasive surgical procedures and can be very effective when performed in selected children and in specialized centres by physicians experienced in rigid and flexible bronchoscopy. © The Author 2014.

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
