    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” 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

    Enforcing surveillance of antimicrobial resistance and antibiotic use to drive stewardship: a quality improvement intervention in the paediatric area of the Verona University Hospital

    Background: Antibiotic Stewardship (AS) interventions in paediatric settings are still poorly standardised in terms of methodology, assessment parameters and the clinical outcomes to be considered. Below are the results of the ENSURE (ENforcing SUrveillance of antimicrobial Resistance and Antibiotic UsE to Drive Stewardship) study, a quasi-experimental study aimed at improving the appropriateness of antimicrobial prescriptions in the paediatric setting by providing treatment guidelines specifically designed in accordance with locally-collected microbiological surveillance data. Materials and methods: The AS intervention was carried out in the Paediatric medical area of a tertiary referral hospital between March 2021 and June 2023. The key elements of the intervention were: 1) an initial intensive phase (March 2021 - May 2021) conducted by an infectious diseases specialist working full time in the unit in question, in order to observe and identify the training needs regarding antibiotic therapy; 2) processing of customised therapy guidelines drawn up in accordance with local microbiological susceptibility data, provided to prescribing personnel in January 2022 and that were also available for consultation using a customised app (Firstline.org); 3) 18-month follow-up phase (February 2022 - June 2023) utilising the <audit and feedback= method. The primary endpoint assessed was consumption of systemic antibiotics (class ATC J01), as calculated using the parameters <Defined daily doses= (DDD), <Days of therapy= (DOT) and <Length of therapy= (LOT), normalised to 1000 patient-days (*1000 PD), for the 18 months following the intervention (period 2022-2023) compared with historical control data for a 12- month period prior to the SARS-COV2 pandemic (2019), using a descriptive method and statistical analysis by means of <Interrupted Time Series Analysis= (ITSA). The secondary endpoints of the study were: 1) distribution of the consumption of antibiotics by WHO AWaRe class; 2) therapeutic appropriateness assessment (using the audit and feedback method); 3) length of stay (LOS); 4) in- hospital mortality; and 5) prevalence of multi-drug resistant (MDR) microorganisms. Results: A consistent reduction in the consumption of antibiotics was recorded, in terms of both DDD *1000 PD, and DOT and LOT *1000 PD. Comparing the data by semesters in order to also take into consideration the expected seasonal fluctuations, the parameter total DDD normalised to *1000 PD decreased by 55% (140 vs 312) between semester I 2022 and semester I 2019, by 47% (203 vs 385) between semester II 2022 and semester II 2019 and by 22% (243 vs 312) between semester I 2023 and semester I 2019. Furthermore, the parameter total DOT normalised to *1000 PD decreased by 63% (DOT 270 vs 724) between semester I 2022 and semester I 2019, by 55% (DOT 370 vs 830) between semester II 2022 and semester II 2019 and by 50% (DOT 359 vs 724) between semester I 2023 and semester I 2019. Mean LOT *1000 PD (LOT 232 vs 450) decreased by 48% between semester I 2022 and semester I 2019, by 32% (LOT 319 vs 472) between semester II 2022 and semester II 2019 and by 30% (LOT 313 vs 450) between semester I 2023 and semester I 2019. The ITS analysis showed statistical significance (p<0.01) for the pre- versus post-intervention differences for all 3 consumption assessment parameters (DDD, DOT, LOT). There was a clear change in prescription habits with greater use of <Access= class antibiotics over <Watch= class antibiotics in the post-intervention period for the period 2022-2023. The <Access to Watch= ratio for mean DDD *1000 PD per observation semester was seen to increase progressively from semester I 2019 (ratio: 0.6) to semester II 2022 (ratio: 1.8), with a decrease in semester I 2023 (ratio: 0.8), nevertheless maintaining higher than pre-intervention values. LOS and in-hospital mortality remained constant in the pre- and post-intervention phase. The prevalence of MDR micro-organism infections remained constant and very low in the pre- and post-intervention phases (2019: 9%; 2022 and 2023: 7%). However, there was an increase in Escherichia coli micro-organisms isolated from urine cultures that were resistant to the therapy provided for in the guidelines (2019: 18%; 2022: 34%; semester I 2023: 40%), with an absolute preponderance of amoxicillinclavulanic acid-resistant micro-organisms. During the post-intervention follow-up phase, 42 audits were carried out to assess 713 patients, 214 of whom were receiving antibiotic therapy (mean proportion: semester I 2022 - 29%; semester II 2022 - 32%; semester I 2023 - 29%). In the postintervention phase, prescriptions were found to be appropriate according to the guidelines in a high proportion of subjects, with a consistently upward trend during the follow-up period (semester I 2022: 84%; semester II 2022: 89%; semester I 2023: 93%). Limitations of the study: The inclusion in the study of a control group and a <non-intervention arm= could have provided support for the assessment of any confounders (e.g. patient mix changes, nonavailability of certain active substances, etc.). However, they were not foreseen in the study design because all areas of the Paediatric Medical Area of Verona University Hospital were simultaneously involved in the study, and no other departments with similar characteristics were available at the same location for use as a control group. Conclusions: In this study, the AS intervention appeared to be associated with an improvement in the appropriateness of antibiotic prescriptions and a significant reduction in total antibiotic consumption, as well as with the consolidation of a prescriptive attitude that favoured, whenever possible, the choice of antibiotics in the <Access= class. The electronic tools specifically designed to support prescribers played an important role in promoting compliance with the guidelines and ensuring the longterm sustainability of objectives achieved. Regular monitoring of micro-organism resistance profiles at a local level is essential for appropriately adapting the guidelines for empirical antimicrobial treatment

    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.
