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
Ризико-орієнтоване моделювання довгих логістичних ланцюжків постачання в підприємствах, що розвиваються
No full textThe paper defines and solves the urgent problem of research of long logistics supply chains in developing enterprises. Due to the distribution of the production system as well as to the presence of a large number of remote suppliers of materials, raw materials and components supply plans are threatened. Supply disruptions in their turn may affect the plans of the main production resulting in possible fines, economic losses, and disruptions in supply of manufactured articles to the markets of high-tech and science-intensive products. To study threats and vulnerabilities in supply logistics the risk-oriented approach that considers potential threats using past statistics and expert assessments has been proposed. The objective of the paper is to develop a risk-oriented method to study the existing threats and assess their impact on the vulnerabilities of the logistics chains of the distributed production system. Due to the complexity of the problematic logistics task, the study is conducted in three different stages: development of the method to simulate the risks in long supply chains; identification of possible bottlenecks in the transport system of supply logistics; threat simulation and vulnerability analysis in supply logistics. To model the risks, an agent model is used, in which the accumulation of risks is carried out by passing orders in the transport system. To simulate bottlenecks, a simulation event model is used, in which large queues that occur in the transport system are analyzed. A stochastic simulation model is used to model threats and vulnerabilities. The new scientific results are risk-oriented method of long logistics supply chains simulation; simulation of supply logistics threats and vulnerabilities. Mathematical methods used: risk theory; simulation event modeling; agent modeling; queuing theory. The proposed approach as a set of developed simulation models should be used to plan the supply of developing production.Ставится и решается актуальная задача исследования длинных логистических цепочек поставки в развивающихся предприятиях. Из за распределенности производственной системы и наличия большого количества отдаленных поставщиков материалов, сырья и комплектующих, возникают угрозы срыва планов снабжения, что отображается на планах основного производства в виде их нарушениях, которые приводят к возможностям штрафов, экономических потерь и нарушений поставки произведенной продукции на рынки высокотехнологичных и наукоемких изделий. Для исследования угроз и уязвимостей в логистике снабжения предложен риск-ориентированный подход, который учитывает возможные угрозы с помощью прошлой статистики и оценок экспертов. Целью работы является разработка риск-ориентированного метода для исследования существующих угроз и оценка их влияния на уязвимости логистических цепочек распределенной производственной системы. Из-за сложности проблемной логистической задачи, исследование проводится в три этапа: разработка метода моделирования рисков в длинных логистических цепочках поставок; определение возможных узких мест в транспортной системе логистики снабжения; моделирование угроз и анализ уязвимостей в логистике поставки. Для моделирования рисков используется агентная модель, в которой осуществляется накопление рисков путем прохождения заявок в транспортной системе. Для моделирования узких мест используется имитационная событийная модель, в которой анализируются большие очереди, возникающие в транспортной системе. Для моделирования угроз и уязвимостей используется стохастическая имитационная модель. Новыми научными результатами являются: риск-ориентированный метод имитационного моделирования длинных логистических цепочек поставок; моделирование угроз и уязвимостей логистики снабжения. Использованы математические методы: теория рисков; имитационное событийное моделирование; агентное моделирование; теория массового обслуживания. Предложенный подход в виде комплекса разработанных имитационных моделей целесообразно использовать при формировании планов снабжения развивающегося производства.Ставиться та вирішується актуальна задача дослідження довгих логістичних ланцюжків постачання в підприємствах, що розвиваються. З-за розподіленості виробничої системи та наявності великої кількості віддалених постачальників матеріалів, сировини та комплектуючих, виникають загрози зривів планів постачання, що відображується на планах основного виробництва у вигляді їх порушень, які призводять до можливих штрафів, економічних втрат та порушенню постачання виробленої продукції на ринки високотехнологічних та наукоємних виробів. Для дослідження загроз та вразливостей у логістиці постачання запропоновано ризико-орієнтований підхід, який враховує можливі загрози з допомогою минулої статистики і оцінок експертів. Метою роботи є розробка ризико-орієнтованого методу для дослідження існуючих загроз та оцінка їх впливів на вразливості логістичних ланцюжків розподіленої виробничої системи. З-за складності проблемної логістичної задачі, дослідження проводиться у три етапи: розробка методу моделювання ризиків в довгих логістичних ланцюжках постачання; визначення можливих вузьких місць в транспортній системі логістики постачання; моделювання загроз та аналіз вразливостей в логістиці постачання. Для моделювання ризиків використовується агентна модель, в якій здійснюється накопичення ризиків шляхом проходження заявок в транспортній системі. Для моделювання вузьких місць використовується імітаційна подійна модель, в якій аналізуються великі черги, які виникають в транспортній системі. Для моделювання загроз та вразливостей використовується стохастична імітаційна модель. Новими науковими результатами є: ризико-орієнтований метод імітаційного моделювання довгих логістичних ланцюжків постачання; моделювання загроз та вразливостей логістики постачання. Використані математичні методи: теорія ризиків; імітаційне подійне моделювання; агентне моделювання; теорія масового обслуговування. Запропонований підхід у вигляді комплексу розроблених імітаційних моделей доцільно використовувати при формування планів постачання виробництва, що розвивається
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

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.
