Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
QuantiFERON TB-gold conversion is not uncommon in psoriasis patients under anti-TNF-α
Tuberculosis (TB) screening and eventual TB infection prophylaxis in case of screening positivity for latent TB infection (LTBI) are mandatory before starting a biologic treatment for psoriasis.1 Indeed, opportunistic infections reactivation, especially LTBI, is one the main risk during biologic therapy, in particular with tumour necrosis factor (TNF)-α inhibitors. It is already known that TNFα plays a major role in the initial and long-term control of TB
Repigmentation of White Forelock in a Familial Case of Piebaldism Reported via Teledermatology in the COVID-19 Era
Piebaldism is a rare autosomal dominant disorder characterized by leucoderma with leucotrichia. We describe a case of white forelock repigmentation in an infant with piebaldism, thanks to a photograph sent by the patient's mother to our dermatology clinic, during COVID-19 pandemic
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
A new proprietary gel containing glabridin, andrographolide, and apolactoferrin improves the appearance of epidermal melasma in adult women: A 6-month pilot, uncontrolled open-label study
Background: Melasma—a localized chronic acquired hypermelanosis—is common in adult women and it is difficult to treat. Aims: We designed a pilot, uncontrolled open-label study to evaluate the appearance of epidermal melasma after 6 months of twice-daily application of a nonprescription proprietary gel formulation containing glabridin, andrographolide, and apolactoferrin. Patients/Methods: A total of 40 Caucasian women with epidermal melasma (Fitzpatrick skin types II-VI) were enrolled. The study endpoints included standardized clinical photography, determination of Melasma Area and Severity Index (MASI) scores, spectrocolorimeter X-Rite analysis, in vivo reflectance confocal microscopy (RCM), and self-assessment of cosmetic acceptability. Results: All endpoints showed a statistically significant improvement of epidermal melasma from baseline to the end of the study. There were no dropouts and cosmetic acceptability was rated as excellent by all of the study patients. The only observed adverse event was a mild, transient xerosis (n = 3). Conclusions: Favorable outcomes, as demonstrated by investigator and instrumental assessments, were demonstrated using a proprietary gel for the treatment of epidermal melasma in adult women. Our results need to be confirmed in independent placebo-controlled studies
