    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

    Яглицький, Ю. К. Використання інформаційних моделей для забезпечення технологічності конструкцій судна на етапах проєктування = The use of information models to ensure the manufacturability of ship structures at the design stages / Ю. К. Яглицький // Зб. наук. пр. НУК. – Миколаїв : НУК, 2021. – № 3 (486). – С. 25–31.Наразі забезпечення технологічності заведено відносити до формалізованих завдань технологічної підготовки виробництва у суднобудуванні. Відпрацювання виробу на технологічність – складне завдання, під час вирішення якого конструктор і технолог повинні не тільки забезпечити високий технічний рівень й експлуатаційні якості створюваного виробу, але й сповна врахувати вимоги виробництва, тобто забезпечити його виробничу технологічність. Сучасний підхід до організації конструкторсько-технологічного проєктування в умовах використання інформаційних моделей виробу полягає в необхідності паралельної розробки конструкції, технології та виробничої системи. Враховуючи, що останнім часом центр значення робіт із забезпечення технологічності конструкцій корпусу судна зміщується на етапи проєктування, важливо забезпечити інформаційний супровід процесів управління технологічністю на цих етапах. Необхідні детальний аналіз і точний опис процесів, що здійснюються на етапах розробки технічного завдання, технічної пропозиції (скороченого проєкту судна), ескізного та технічного проєктів. Для цього можна використовувати дослідження, які включають формування інформаційної моделі об’єкта розробки та забезпечення виробничої й експлуатаційної технологічності конструкції виробів. У роботі розглянуто інформаційні моделі процесів забезпечення технологічності судна (суднових конструкцій) на етапах розробки технічного завдання, технічної пропозиції, ескізного та технічного проєктів. Інформаційне моделювання процесів управління технологічністю на ранніх етапах проєктування з детальним аналізом і точним описом процесів дозволить забезпечити фахівців (конструкторів, технологів) інформацією для створення керівних впливів щодо забезпечення необхідного рівня технологічності, підвищення об’єктивності результатів її оцінки. В якості сучасного інструменту інформаційного моделювання та аналізу пропонується використовувати технологію IDEF. Моделі, побудовані з використанням технології SADT, дозволяють ефективно проводити аналіз конструкції виробу, встановити послідовність проведення робіт, виявити фактори, що впливають на якісну та кількісну оцінку технологічності.Currently, the provision of manufacturability is usually attributed to the difficult-to-formalize tasks of technological preparation of production in shipbuilding. Testing a product for manufacturability is a complex task, in solving which the designer and technologist must not only ensure a high technical level and operational qualities of the product being created, but also fully take into account the requirements of production, that is, ensure its production manufacturability. The modern approach to the organization of design and technological design in the conditions of using information models of the product is the need for parallel development of the design, technology and production system. Taking into account that recently the center of gravity of work on ensuring the manufacturability of the ship’s hull structures has shifted to the design stages, it is important to provide information support for the processes of managing the manufacturability at these stages. A detailed analysis and an accurate description of the processes occurring at the stages of developing the technical specification, technical proposal (abbreviated ship design), draft and technical projects are required. To do this, you can use such research areas that include the formation of an information model of the object of development and ensuring the production and operational manufacturability of the product design. The paper considers information models of processes for ensuring the manufacturability of a vessel (ship structures) at the stages of developing a technical task, a technical proposal, draft and technical projects. Information modeling of technological efficiency management processes at the early stages of design with a detailed analysis and accurate description of the processes will allow providing specialists (designers, technologists) with information to create control actions to ensure the necessary level of technological efficiency, increasing the objectivity of the results of its evaluation. It is proposed to use IDEF technology as a modern tool for information modeling and analysis. Models built using SADT technology allow us to effectively analyze the design of the product, establish the sequence of work, identify factors that affect the qualitative and quantitative assessment of manufacturability

    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

    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

    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.
