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
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Assessment of Reported Adverse Events After Interchanging Between TNF-α Inhibitor Biosimilars in the WHO Pharmacovigilance Database
No full textBackground and ObjectiveObservational studies have shown that a significant proportion of patients interchanging between tumor necrosis factor-alpha inhibitor biosimilars withdraws from the new treatment because of adverse effects. We aim to analyze adverse events related to interchanging from tumor necrosis factor-alpha (TNF-alpha) inhibitor reference products to biosimilars and between biosimilars reported in the World Health Organization pharmacovigilance database.MethodsWe extracted all cases reporting the Medical Dictionary for Regulatory Activities term "Product substitution issue (PT)" for TNF-alpha inhibitors. Then, we analyzed and categorized all adverse events reported in more than 1% of cases. We compared the adverse events reported according to reporter qualification, type of switch, and type of TNF-alpha inhibitor using Chi(2) tests. We conducted a network analysis coupled with a clustering approach to identify syndromes of co-reported adverse events.ResultsIn the World Health Organization pharmacovigilance database, 2543 cases and 6807 adverse events related to TNF-alpha inhibitor interchangeability have been reported up to October 2022. Injection-site reactions were the most reported adverse events with 940 cases (37.0%), followed by modifications in drug effect in 607 cases (23.9%). Musculoskeletal, cutaneous, and gastrointestinal disorders linked to the underlying disease were reported in 505 (20.0%), 145 (5.7%), and 207 (8.1%) cases, respectively. Adverse events non-related to the underlying disease were nonspecific (n = 458, 18.0%), neurologic (n = 224, 8.8%), respiratory (n = 132, 5.2%), and psychological disorders (n = 64, 2.5%). Injection-site reactions and infection-related symptoms (e.g., nasopharyngitis, urinary tract infection, lower respiratory tract infection) were more reported by non-healthcare professionals while adverse events related to reduced clinical efficacy (e.g., drug ineffective, arthralgia, psoriasis) were more reported by healthcare professionals. The proportions of injection-site reactions were higher when switching between biosimilars of the same reference product, but the proportions of adverse events related to reduced clinical efficacy (e.g., psoriasis, arthritis, psoriatic arthropathy) were more reported when switching from a reference product. The main differences in the proportions of reported cases between adalimumab, infliximab, and etanercept were driven by symptoms related to the underlying targeted diseases, except for a higher reporting rate of injection-site pain with adalimumab. Adverse events evocative of hypersensitivity reactions were reported in 192 (7.6%) cases. Most of the network clusters concerned non-specific adverse events or were related to reduced clinical efficacy.ConclusionsThis analysis highlights the burden of patient-reported adverse events when interchanging between TNF-alpha inhibitor biosimilars, notably injection-site reactions, non-specific adverse events, and symptoms related to reduced clinical efficacy. Our study also highlights differences in reporting patterns between patients and healthcare professionals and depending on the type of switch. The results are limited by missing data, the lack of precision of the coded Medical Dictionary for Regulatory Activities terms, and by the variability of reporting rate of adverse events. Thus, incidence rates of adverse events cannot be inferred from these results

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
