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
Video-Assisted Anal Fistula Treatment (VAAFT) for complex anorectal fistula: efficacy and risk factors for failure at 3-year follow-up
No full textBackground: The aim of this study was to assess the 3-year objective and subjective outcomes of patients with complex anorectal fistula treated with Video-Assisted Anal Fistula Treatment (VAAFT). Furthermore, we evaluated the risk factors associated with recurrence. Methods: All consecutive patients with complex anorectal fistula who underwent VAAFT in Beata Vergine Hospital of Mendrisio, Switzerland, from January 2013 to January 2016, were enrolled. Patients with suspicion or diagnosis of Crohn’s disease, malignancy, previous history of radiotherapy or radical pelvic surgery were excluded. Preoperative clinical assessment based upon medical history, physical examination and endosonography, was performed in all patients. Data regarding subjective outcomes (the Patient Global Impression of Improvement, patient satisfaction scores and Wexner score), objective cure rate (absence of fistula at clinical examination), and adverse events were collected during follow-up. Uni and multivariate analysis were performed to investigate outcomes. Results: One hundred and four patients had VAAFT. At 3-year follow-up, 96 patients (92.3%) were available for the evaluation. At 3 years after surgery, 81 of 96 patients (84.4%) declared themselves cured (p = 0.60). Similarly, at 3-year evaluation, 80 of 96 patients (83.3%) were objectively cured (p = 0.52). No serious intraoperative or postoperative complications were reported. All recurrences were treated with a repeat VAAFT procedure resulting in a complete healing. Uni and multivariate analysis of variables potentially involved in the failure of VAAFT showed that age ≥ 50 years was the only factor associated at risk of recurrence. Conclusions: VAAFT is a highly effective safe procedure for the treatment of anorectal fistula, with a low recurrence rate at 3-year follow-up. However, our study demonstrated that age ≥ 50 years is a risk factor for failure of VAAFT
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
