Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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
Aplicação da dinâmica de sistemas na implementação de modelo computacional para estimação da qualidade do efluente de lagoas facultativas
No full textThis paper presents the preliminary results of the development of a computer model to predict the quality of the facultative pond effluent proposed by FRITZ (1985) with a system dynamics approach, using the software VenSim PLE ®. The model considers the mass balance applied in a complete mixing reactor, consisting of the simultaneous resolution of twelve differential equations in time for the determination of effluent concentrations of crude COD, soluble COD, dissolved oxygen, Organic and Inorganic Nitrogen, Total Kjeldhal Nitrogen, Ammoniacal Nitrogen, Organic and Inorganic Phosphorus, Alkalinity, Hydrogenionic Concentration (pH). For its calibration there was the division into two stages: verification and validation. For the verification, the following parameters were simulated: soluble COD, Ammoniacal Nitrogen, Total Phosphorus, pH, DO and temperature, were compared with the results obtained by Silva (1982) for a pilot scale facultative lagoon located in Campina Grande (PB), which operates as a complete mixing reactor and whose sampling were composed. The results of the simulations obtained for the verification were considered satisfactory, standing out the soluble COD, OD and temperature, which were similar to those obtained in the field. For validation, the following parameters were analyzed: crude COD, soluble COD, Kjeldhal Total Nitrogen, Ammoniac Nitrogen, pH, OD and Alkalinity, which were compared with the results obtained by Pedrelli (1997) for a full scale facultative lagoon located in Balneário Camburiú (SC). The results of the simulations obtained for Alkalinity and pH were the ones that presented the greatest similarity with those obtained in the field, soluble COD had satisfactory results, but for the other parameters the simulation results were slightly higher than those observed. Such variations may be associated to disregarding the variability of the affluent quality in the facultative pond, the possibility of compartmentalization of the liquid volume, which would remove the model from the complete mixing condition, as well as the fact that the samples used in the validation were obtained punctually and not in a compound way.Não recebi financiamentoEste trabalho apresenta os resultados do desenvolvimento de modelo computacional para previsão da qualidade do efluente de lagoa facultativa, proposto por FRITZ (1985) com abordagem da dinâmica de sistemas, sendo utilizado o software VenSim PLE ®. O modelo considera o balanço de massa aplicado em um reator de mistura completa, consistindo na resolução simultânea de doze equações diferenciais no tempo para determinação das concentrações efluentes da DQO bruta, DQO solúvel, oxigênio dissolvido, Nitrogênio Orgânico e Inorgânico, Nitrogênio Total Kjeldhal, Nitrogênio Amoniacal, Fósforo Orgânico e Inorgânico, Alcalinidade, concentração hidrogeniônica (pH). Para a calibração do modelo, foram realizadas duas etapas: verificação e validação. Para a verificação foram feitas simulações para os parâmetros: DQO solúvel, Nitrogênio Amoniacal, Fósforo Total, pH, OD e temperatura, que foram comparados com os resultados obtidos por Silva (1982) para uma lagoa facultativa em escala piloto localizada em Campina Grande (PB) operada como um reator de mistura completa e amostragem composta. Os resultados das simulações obtidos para a verificação foram considerados satisfatórios, destacando-se a DQO solúvel, o OD e a temperatura, cujos resultados estavam similares com os obtidos em campo. Para validação foram realizadas simulações para os parâmetros: DQO bruta, DQO solúvel, Nitrogênio Total Kjeldhal, Nitrogênio Amoniacal, pH, OD e Alcalinidade, que foram comparados com os resultados obtidos por Pedrelli (1997) para uma lagoa facultativa em escala plena localizada em Balneário Camburiú (SC). Os resultados das simulações obtidos para Alcalinidade e pH foram os que apresentaram maior semelhança com os obtidos em campo. A comparação dos valores da DQO solúvel foram satisfatórios, porém para os demais parâmetros, os resultados da simulação foram ligeiramente superiores aos observados. Tais variações podem estar associadas à desconsideração da variabilidade da qualidade do afluente na lagoa facultativa, a possibilidade de ocorrência de compartimentalização do volume líquido, o que afastaria o modelo da condição de mistura completa, assim como o fato das amostras usadas na validação terem sido obtidas pontualmente e não de maneira composta
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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.
