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
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
Análise e desenvolvimento de um sistema impressor Raster de formato extra-largo
Get PDFTese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia Mecânica.O presente trabalho visa contribuir para o desenvolvimento de sistemas de impressão, apresentando uma proposta de análise de dispositivos para impressão e desenvolvendo um sistema impressor raster de formato extra-largo, necessidade especial e atual das micro e pequenas empresas de comunicação visual. Destina-se a realizar impressões de mídias sem emendas, na ordem dos metros (3,5m de boca), com resolução adequada (menor) para visualização acima dos 6 m possibilitando maiores velocidades de impressão, de até 40 m2/h e a menor custo. Devido a sua concepção com base vazada pode imprimir através do plano de base diretamente sobre a superfície final, o que permite realizar impressões tanto sobre superfícies rígidas como filmes flexíveis (papel, plástico, lona, etc). O protótipo do sistema impressor proposto consta de três principais módulos: O módulo de pós-processamento que realiza a leitura da informação de impressão, condiciona os sinais e gera os comandos específicos que atuam nos sistemas de acionamento localizados no segundo módulo, o conjunto impressor, estes comandos movimentam adequadamente os eixos do pórtico X-Y para que o terceiro módulo, o cabeçote impressor, realize a impressão propriamente dita ao comando de sinais elétricos. A leitura da informação de impressão, cor e sua posição x,y no desenho para cada ponto, foi implementada no módulo de pós-processamento utilizando dois métodos, um via hardware utilizando a informação existente numa impressora comum durante seu funcionamento e outro via software diretamente do gráfico a ser impresso. Com o objetivo de melhor conhecer e otimizar a resposta dinâmica do conjunto impressor, os dois eixos de movimento da máquina foram modelados obtendo suas funções de transferência. A simulação destas funções permite conhecer seu comportamento e conseguir um ajuste adequado dos parâmetros de controle da placa controladora de movimentos. Após todos estes processos, foram realizados com o conjunto impressor vários ensaios de resposta no tempo para posicionamento e trajetória, até atingir o comportamento especificado. O software gerenciador projetado integra todos estes sub-sistemas e comanda o funcionamento do protótipo impressor desenvolvido. Com o sistema funcionando realizaram-se testes de qualificação de impressão em formato extra-largo, os quais já atendem satisfatoriamente as exigências impostas. Atualmente o protótipo desenvolvido encontra-se em fase experimental e de otimização de funcionamento. This research work is a contribution to design printing systems, presenting a proposal in order to analyze devices and to develop a raster printer system having extra-large format, specially and update need by visual communication enterprises, having small and medium size. Such printing system is intended for print large-scale images within the range of 3,5 meters of mouth with adequate resolution (smaller) for visualization above 6 meters supporting printing velocities up to 40 m2/h and lower cost. Due to its conception it is able to print directly through its base plan on the final surface, allowing printing on rigid surfaces as well as on flexible films (papers, plastic, canvas etc#) The prototype of the proposed printing system has three main modules: The post-processing module reads the information to be printed, sets the signals and generates the specific commands that actuate on the specific drives placed on the second module. The printing head in the third module follows the program feeding the drives of the x - y gantry in order to do the printing movements. The reading of the printing color and x - y position informations for each point in the drawing has been implemented in the post-processing module using two methods, one by hardware, using an existing information in a standard printer in use, and another way, directly from the printing graphics file. For to better know how to optimize the dynamic behavior of the printing system the two motion axis have been modeled in order to get its transfer functions. The simulation of this functions allows to know its behavior in order to help obtain an adequate values set of the parameters of the motion controller. After these procedures, systematic time measurements helped to match the given specifications. The main implemented system software integrates all these sub-systems and commands the printer machine. Qualifying printing tests using extra-large format show that the system supports well the imposed requirements. Right now the developed prototype is in experimental tests aiming optimization
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.
