    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

    CILJ ISTRAŽIVANJA: Cilj ovog istraživanja je bio dobiti podatke o stopi ostanka bolesnika sa seronegativnom spondiloartropatijom na biološkoj terapiji, usporediti prosječno trajanje terapije između tih bolesnika i bolesnika sa reumatoidnim artritisom kao i utvrditi učestalost i najčešće razloge prekida terapije. MATERIJALI I METODE: Obuhvaćena su 72 bolesnika s dijagnozom neke od seronegativnih spondiloartropatija liječena biološkom terapijom u sklopu KBC-a Split u razdoblju od svibnja 2005. do 01. siječnja 2016. godine. Podaci su prikupljeni iz arhive povijesti bolesti Zavoda za reumatologiju i kliničku imunologiju i Kliničkog bolničkog centra Split. REZULTATI: Od ukupnog broja bolesnika sa SpA (N=72) 46 je bilo muškaraca (63,8%), a 22 žene (36,2%). 44,4% je bilo klasificirano kao psorijatični artritis, 31,9% kao nediferencirani spondiloartritis te najmanje, 23,6% kao ankilozantni spondilitis. Prosječna dob naših bolesnika bila je 47,7 godina (24-71 godinu). Najdulje prosječno trajanje biološke terapije zabilježeno je za lijek etanercept (35,55±25 mjeseci), dok se lijekovi adalimumab (30,44±24 mjeseci) i infliksimab (22,5±19 mjeseci) nalaze na drugom i trećem mjestu prema duljini trajanja terapije. Ipak, statistički značajna razlika među ispitivanim lijekovima u liječenju SpA nije utvrđena (p 0,146), kao što nema ni značajne razlike u trajanju biološke terapije između bolesnika s RA i SpA (p 0,926). Najdulje prosječno trajanje terapije pokazuju bolesnici mlađe životne dobi (24 - 30 godina). U 31% bolesnika je došlo do prekida terapije prvim biološkim lijekom. Tako je od ukupno 107 primjenjenih različitih tretmana biološke terapije 32,7% bilo primjenjeno kao drugi, treći ili slijedeći biološki lijek po redu. Kao najčešći razlog prekida terapije pokazala se neučinkovitost lijeka s čak 86,8%, dok su nuspojave na drugom mjestu s 13,2%. Od njih se spominju infuzijska reakcija, subfebrilitet, pojava difuznih bolova u tijelu kao i pojava vaskulitičnih lezija na koži, dok pojava hematoloških ili drugih solidnih zloćudnih tumora nije zabilježena niti u jednog od promatrana 72 bolesnika. Lijek infliksimab pokazuje najveću učestalost prekida terapije u 50% bolesnika, u usporedbi s 22,7% prekida na terapiji golimumabom i 0% kod terapije certolizumabom. ZAKLJUČAK: Najčešće primjenjivan lijek u liječenju SpA je adalimumab, a najdulje prosječno trajanje terapije zabilježeno je za lijek etanercept. Ipak, nema značajne razlike u duljini trajanja terapije među pojedinim biološkim lijekovima u liječenju SpA, kao što nema ni značajne razlike što se trajanja biološke terapije između RA i SpA bolesnika tiče. Najbolji odgovor na terapiju pokazuju mlađi bolesnici. Prekid biološke terapije je bio nužan u 31% bolesnika, a kao najčešći razlog nužnosti prekida ističe se neuspjeh terapije dok su nuspojave lijekova na drugom mjestu razloga. Pojava hematoloških ili solidnih zloćudnih tumora kao nuspojava nije zabilježena niti u jednog bolesnika. Najveću učestalost prekida terapije pokazuje lijek infliksimab, a najmanju lijek certolizumab.OBJECTIVES: The aim of this study was to define retention rate of biological therapy in patients with seronegative spondiloarthropaties (focus on AS, PsA, uSpA), to define prevalence and the main causes of biological treatment discontinuation but also to compare the mean therapy duration of biological therapy between RA and SpA patients. METHODS: A census of 72 patients with SpA for the period from May 2005 to January 2016 has been conducted using hospital records for case identification. RESULTS: This cross-sectional study included 72 patients with SpA. 46 of them were men (63.8%) and 22 women (36.2%). Also, 44.4% were classified as psoriatic arthritis, 31.9% as undifferentiated spondiloarthritis and 23.6% as ankylosing spondylitis. The mean age of our patients was 47.70 (24-71 years). The mean therapy duration was the longest for drug etanercept (35.55±25 months), and drugs adalimumab (30.44±24 months) and infliksimab (22.5±19 months) were situated on the 2nd and 3rd place according to the therapy duration. There is no statistically significant difference between drugs in SpA patients (p value 0.146), like there is no significant difference in therapy duration between RA and SpA patients (p value 0.926). The longest therapy duration showed younger patients from 24 to 30 years. 31% of patients discontinued therapy during time. 32,7% of total 107 different biological treatments were applied as second, third or other following drug in order. The main cause of drug discontinuation was inefficacy in 86.8% patients, and side effects were on the second place with 13.2%. The most common side effects were infusion reaction, subfebrility, diffuse body pain and occurrence of diffuse vasculitic lesions on the skin while occurrence of hematological or other solid malignancies has not been reported in any of our 72 patients during observational time. Drug infliksimab had the highest discontinuation rate with 50% in contrast to golimumab (22.7%) and certolizumab (0%). CONCLUSION: The most commonly used drug in the therapy of SpA patients is adalimumab and the mean therapy duration was the longest for drug etanercept. The best therapy response showed younger SpA patients. There is no statistically significant difference between drugs in SpA patients according to therapy duration like there is no difference in therapy duration between SpA and RA patients. Treatment discontinuation occurred in 31% of patients and the main cause of drug discontinuation was inefficacy while side effects were on the second place. Hematological or other solid malignancies as side effects have not been reported in any of 72 patients. Drug infliksimab showed the highest and drug certolizumab the lowest discontinuation rate

    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

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    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

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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 text
    We 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

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In 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.
