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
Long-term clinical evaluation of laparoscopic management of large hiatal hernias
No full textBACKGROUND: Large hiatal hernias (LHH) account for 5-10% of all hiatal hernias. Surgery of LHH should be associated with low rates of postoperative complications and recurrences, to guarantee a favorable quality of life (QoL). Data on long-term results of laparoscopic repair of LHH are lacking. The objective of our study is to evaluate the long-term clinical outcomes of laparoscopic LHH management in a high-volume experienced center.
METHODS: Patients who had undergone elective laparoscopic repair of LHH between January 1992 and December 2008 at the Center of Minimally Invasive Surgery of the Department of Surgical Sciences, University of Turin, Italy were included. Preoperative and intraoperative data were collected from patients’ charts. Patients were clinically evaluated at long-term postoperative follow-up to assess control of symptoms, degree of satisfaction with surgery, and QoL.
RESULTS: At mean follow-up of 240 months (range 168-348), 81 patients were available for clinical evaluation. Severe heartburn was reported by six patients (7.4%), while severe post-prandial epigastric pain by three (3.7%). Recurrent coughing episodes were described by six patients (7.4%), while occasional mild episodes of transient dysphagia by 13 (16%). No gas bloat detected. Proton Pump Inhibitors were taken by 22 patients (27.2%) to control symptoms. The Modified Italian Gastroesophageal Reflux Disease-Health Related Quality of Life (MI-GERD-HRQL) score decreased significantly from 40 to 7 (P<0.0001) postoperatively. Satisfaction was achieved in 76 patients (93.8%) with an average satisfaction index of 8.6 (IQR 8-10).
CONCLUSIONS: Laparoscopic LHH repair is effective when performed in a specialized center, with long-lasting significant improvements of symptoms and QoL
The Thunderbeat and Other Energy Devices in Laparoscopic Colorectal Resections: Analysis of Outcomes and Costs
Full text linkThe THUNDERBEAT™ (TB) is a recently developed energy-based device. To date, there are no clinical studies comparing TB and other energy sources, such as standard electrosurgery (ES), ultrasonic coagulating shears (US) and electrothermal bipolar vessel sealers (EBVS) in patients undergoing laparoscopic colorectal resection (LCR). The aim of this study was to compare outcomes and costs in patients undergoing LCR with TB, US, EBVS, or ES for both benign and malignant colorectal diseases
