    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    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

    Multidisciplinary studies of schistosomiasis and HIV on the shoreline of Lake Malawi: A longitudinal cohort study of male genital schistosomiasis (MGS) among fishermen in Mangochi District.

    Male genital schistosomiasis (MGS) is a specific chronic manifestation of schistosomiasis associated with schistosome eggs and related pathologies in the genital system of men inhabiting or visiting endemic areas. Despite description of the first recognised MGS patient by Madden in 1911, the epidemiology, diagnostic testing and case management of MGS are not well described owing to limited research and diminishing focus over several decades. Furthermore, as the human immunodeficiency virus (HIV) epidemic expands across sub-Saharan Africa (SSA), there is renewed interest in MGS owing to plausible but as of yet under-explored interactions with HIV. To shed new light on MGS, a longitudinal cohort study was conducted among fishermen along the southern shoreline of Lake Malawi, an endemic area in SSA to investigate the prevalence of MGS, its associated knowledge, attitudes and practices (KAP), and determine the potential increase of viral shedding in semen of HIV-positive men with MGS. A systematic review conducted prior to the onset of the research fieldwork describing the MGS epidemiology, clinico-pathological manifestations, diagnostic techniques and treatment outlined and informed the current approach to the body of research presented here. Fishermen aged 18+ years were recruited into the study after providing informed written consent and individual questionnaires were administered to assess their KAP associated with MGS. Thereafter, participants submitted urine, semen, and blood for point-of-care (POC) field parasitological tests, and later laboratory-based molecular polymerase chain reaction (PCR), and HIV VL analyses. In addition, transabdominal and scrotal ultrasonography to assess the pathological effects of MGS on their genital organs were performed. Praziquantel therapy was provided to all participants, together with the follow-up diagnoses and treatment dates after 1, 3, 6 and 12-months’ intervals. 376 fishermen (320 HIV-negative and 56 HIV-positive on Antiretroviral therapy (ART)) aged between 18 and 70 years (median: 30.0 years), were recruited into the study, and had questionnaires interviews. At baseline, prevalence of UGS (S. haematobium eggs in urine) was 17.1% (n = 210, median: 2.3 per 10 ml, range: 0.1 – 186.0), 3.8% had a positive point-of-care circulating cathodic antigen (POC-CCA) indicative of intestinal S. mansoni infection, while MGS prevalence was 10.4% by semen microscopy (n = 114, median: 5.0, range: 0.1 – 30.0) and 26.5% by real-time PCR (n = 65, Ct value range: 18.8 – 36.6). More participants (66.7%) with schistosome eggs in semen were observed to not have any eggs in their urine. 6.9% of participants (n = 130) were observed to have pathological lesions in their genital organs on ultrasonography. For 15 HIV-MGS cases and 16 HIV-only controls who submitted paired blood and semen samples during the longitudinal study, more cases than controls had detectable and quantifiable VL, which regressed with PZQ. Similarly, the results of the diagnostic tests improved, with negative schistosome egg, real-time PCR in semen and pathological resolution on follow-up. In conclusion, MGS has been observed, via parasitological, molecular and radiological examinations, to be common in local male inhabitants (fishermen) of endemic areas along the south shoreline of Lake Malawi in the SSA region and shown to respond to standard PZQ treatment. Improving availability and accessibility for all people in these areas to PZQ, diagnostic tools for MGS, and combined HIV and schistosomiasis control interventions are advocated to reduce morbidity and improve the lives and reproductive health of men, their partners and communities in endemic areas

    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

    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.
