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
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
Terroir coffee in crops of the district of Araponga - MG
No full textO café é um produto que tem seu valor estipulado em função da sua qualidade e esta é dependente das características do local onde esse é produzido. A diferenciação dos cafés através da noção de terroir permite determinar áreas potenciais para a produção de cafés especiais e caracterizar o tipo de café característico dessas áreas, explorando suas potencialidades. O estudo dos terroirs está relacionado à compreensão de um território comumente pequeno, em que diferentes fatores locais conferem qualidades distintas aos produtos. O objetivo desse trabalho foi caracterizar e delimitar terroirs de produção de café de lavouras no município de Araponga MG, definir a influência de variáveis climáticas, de solo e da topografia sobre os terroirs e a qualidade, e utilizar um sistema de visão artificial para estimar a qualidade da bebida. Os dados foram coletados em quatro lavouras do município de Araponga MG, as quais foram escolhidas considerando as diferenças significativas entre si, principalmente no que diz respeito a altitude das mesmas. Foram coletadas amostras de frutos cereja em cada um dos talhões de cada lavoura, as quais foram utilizadas para determinar a qualidade global do café e suas características sensoriais peculiares. Desses frutos mediram-se o teor de sólidos solúveis (º Brix) com auxílio de um refratômetro portátil, o comportamento espectral utilizando um espectroradiômetro com iluminação artificial e as características colorimétricas através de imagens digitais obtidas com câmeras fotográficas. A influência do clima sobre os terroirs e sobre a qualidade do café foi avaliada em função da umidade relativa do ar, temperatura, radiação solar e número médio de horas de luz. O solo dos terroirs foi caracterizado com base em seus atributos físicos texturais e quanto à sua formação e material de origem. A qualidade do café foi avaliada por meio da análise de suas características físicas e pela análise sensorial, segundo as regras de competições nacionais e internacionais da Associação Americana de Cafés Especiais (SCAA). A definição dos terroirs de produção de café foi feita à partir das notas globais dos cafés das fazendas e também de suas características peculiares. A fazenda do Boné se destacou em relação às demais com base na qualidade global média e também nos valores médios de doçura e sabor dos cafés. O município de Araponga MG possui mais de um terroir de produção de café caracterizado por dois distintos extratos de altitude e que exercem influencia singular sobre a qualidade dos cafés colhidos, tornando-os diferenciáveis. A qualidade do café é dependente do terroir, e este, por sua vez, da altitude, da posição da lavoura e das características microclimáticas. A qualidade global do café apresenta correlação significativa com os valores de Banda R e reflectância dos frutos. Os valores de º Brix não apresentaram correlação significativa com a qualidade do café. É possível utilizar os valores de Banda R e de reflectância na banda do vermelho dos frutos cereja para a estimativa dos valores de qualidade global do café, sendo viável a adoção de um sistema simplificado para aquisição das imagens.The value of the coffee is set depending on their quality and this is dependent on the characteristics of where this is produced. The differentiation of coffee through the notion of terroir to determine potential areas for the production of specialty coffees and coffee characterize the type characteristic of these areas, exploring its potential. The study of terroirs is related to the understanding of a small territory, in which different local factors provide different qualities of products. The aim of this study was to characterize and define terroirs production of coffee plantations in the municipality of Araponga - MG, define the influence of climatic variables, soil and topography on the terroirs and quality, and use an artificial vision system for estimating quality of the drink. Data were collected at four farms in the municipality of Araponga - MG, which were chosen considering the significant differences between them, especially in respect of the same altitude. Samples were collected from cherry fruit in each of the plots of each crop, which were used to determine the overall quality of coffee and their sensory characteristics. These fruits were measured the total soluble solids (º Brix) using a portable refractometer, the spectral behavior using a spectroradiometer with artificial lighting and the colorimetric characteristics through images taken with digital cameras. The influence of climate on the terroirs and the quality of coffee was evaluated as a function of relative humidity, temperature, solar radiation and average number of hours of light. The soil of terroirs was characterized based on their physical attributes and textural about their training and material. The coffee quality was evaluated by analyzing their physical and sensory analysis, according to the rules of national and international competitions of the Specialty Coffee Association of America (SCAA). The definition of the terroirs of coffee production was made from the notes of the global coffee farms as well as its peculiar characteristics. The farm's cap stood out over others based on the average overall quality and also the average values of sweetness and flavor of coffee. The Araponga District - MG has more of a terroir of coffee production is characterized by two different extracts of altitude and exercise influence on the natural quality of coffee harvested, making them distinguishable. The coffee quality is dependent on the terroir, and this, in turn, altitude, position and characteristics of the crop microclimate. The overall quality of coffee has significant correlation with the values of R band and reflectance of fruits. ° Brix values showed no significant correlation with the quality of coffee. You can use the values of R band and reflectance in the band of red cherry fruit to the estimation of overall quality of coffee, and feasible to adopt a simplified system for image acquisition.Conselho Nacional de Desenvolvimento Científico e Tecnológic
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.
