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
Psoriasis and biological drugs at the time of SARS-CoV-2 infection: a mini review outlining risk of infection, seroprevalence, and safety and efficacy of the BNT162b2 vaccine
No full textObjective The aim of this study is to review the life of patients with psoriasis on biologic therapy during the SARS-CoV-2 pandemic and the relevance of frailty within this context, reviewing studies that describe the course and severity of infection in patients with psoriasis on biologics, the seroprevalence of SARS-CoV-2, and the safety and efficacy of the BNT162b2 vaccine in these patients.Materials and methods The keywords "Psoriasis," "Biologics," "SARS-CoV-2," "COVID-19," and "BNT162b2 Vaccine" were used in various combinations on database engines to find relevant articles on this topic.Results A total of 36 articles were found, with 20 concerning the course, severity, and seroprevalence of SARS-CoV-2 in patients with psoriasis on biologic therapy and 16 concerning safety and efficacy of BNT162b2 in these patients.Discussion Patients with psoriasis on biologic therapy did not have increased seroprevalence compared with the general population, indicating that they were not at an increased risk of SARS-CoV-2 infection compared with the general population. Furthermore, the immunosuppressive action of biologics may be protective, as patients on biologic therapy had better outcomes and less risk of severe infection. The seroconversion rate against SARS-CoV-2 from the BNT162b2 vaccine was similar in both patients with psoriasis on biologics and the general population, indicating that efficacy is not hindered by the biologic therapy. However, the cellular response in population with psoriasis was significantly less intense, and the humoral immune response was weaker than that in the general population, demonstrating that the possibility of tighter vaccination schedules and additional doses may be advantageous in these patients
Efficacy of secukinumab in pediatric patients: description of a case of annular psoriasis followed since neonatal age
No full text15 Years of Intermittent Therapy With Hydroxychloroquine Without Any Loss of Efficacy in Reticular Erythematous Mucinosis
No full textReticular erythematous mucinosis (REM) is a rare dermatological condition characterized by erythematous, reticulated patches and plaques with a slightly infiltrated appearance. REM is classified among cutaneous mucinoses, which are characterized by the accumulation of mucin in the subcutaneous tissues, leading to the formation of characteristic reticulated patches on the skin. The pathogenesis is still debated, but the association with sun exposure seems to play an important role. We present the case of a 54-year-old individual with a history of recurrent erythema on the chest and back. The patient came to our attention in 2007 due to a worsening of symptoms after sun exposure. On clinical examination, the patient presented with pruritic, erythematous patches with a reticulated appearance. A biopsy was performed, which showed the presence of a moderate lymphocytic infiltrate in the dermis, with a perivascular and periappendageal distribution, consisting mainly of T lymphocytes, and deposits of mucin in the superficial dermis, dissecting the collagen bundles. A diagnosis of REM was made, and the patient began treatment with hydroxychloroquine 200 mg per day, with rapid improvement of symptoms. Considering the resolution of symptoms, the therapy was discontinued after 3 months. The patient remained in remission until the following summer when the condition recurred, requiring a new cycle of hydroxychloroquine therapy. The patient has experienced recurrences over the past 15 years during the summer, which responded to hydroxychloroquine therapy, consistently achieving rapid symptom resolution without ever experiencing loss of efficacy or side effects
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
