Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Immunoglobulin subtypes predict therapy response to the biologics in patients with rheumatoid arthritis
No full textTo analyze the effectiveness of rituximab (RTX) versus alternative TNF antagonists (aTNFs) on rheumatoid arthritis (RA) disease activity in different subgroups of patients and relation with extraarticular manifestations of RA and to assess that RF-subsets have potential as predictors of clinical response to RTX. Patients with RA (n = 40, M/F: 3/37) who received aTNFs at least 6 months with good response (group I; n = 20) or discontinued at least one aTNFs because of the ineffectiveness and subsequently received RTX at least one course (group II; n = 20) were retrospectively evaluated. IgM-, IgA-, IgG-rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) levels were measured by ELISA technique. Extraarticular manifestations and radiological scores were also recorded. The mean (SD) age was 51.7 +/- A 6.5 years in group I and 52.1 +/- A 6.1 years in group II patients (p > 0.05). The median disease durations were higher in group II than group I [8.0 (2-30) vs. 13 (3-35) years, respectively, p = 0.04]. Presence of RF [13(61.9 %) vs. 20(100 %) p = 0.001] and extraarticular involvement [5(25 %) vs. 13(65 %) p = 0.01] were higher in group II patients. When Ig-RF subgroups analyzed, all subgroup (IgA, IgM, IgG) levels were higher in group II (p = 0.001, p = 0.05, p = 0.001). IgA-RF levels were significantly high in patients with extraarticular involvement (p = 0.04). Association between high RF levels and having extraarticular manifestations in RA patients may largely be attributed to the IgA isotype
Variations on the Author
Get PDF“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
Get PDFWe 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
