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
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
Effect of thermal environment on breeding performance and energy utilization in broilers
No full textDois experimentos foram realizados com o objetivo de avaliar o efeito da temperatura e do índice de temperatura e umidade (ITU) nas idades pré-inicial e inicial de frangos de corte sobre as alterações provocadas nas partições da energia metabolizável ingerida (EMI) e sobre as exigências de mantença (EMm) e, desempenho. Um terceiro experimento mediu o desempenho subsequente de frangos que foram submetidos a diferentes temperaturas durante os primeiros 14 dias de vida, bem como a composição e rendimentos de carcaça e cortes. Nos experimentos 1 e 2 foi determinado a energia metabolizável (EM) utilizando indicador óxido de cromo, e os resultados das partições da EMI foram determinados a partir da técnica de abate comparativo para cada período avaliado. O desempenho também foi avaliado. Os resultados das variáveis de resposta animal foram submetidos a análise de regressão tendo como variáveis independentes as médias de temperatura e o ITU. Os resultados permitiram determinar no experimento 1 que, para a idade de 1 a 7 dias a média de temperatura de 28,3 °C melhorou os índices de desempenho. A exigência de mantença por peso metabólico nesta idade apresentou menor valor em 30,8 °C, sendo estimada em 163,7 kcal/kg PV0,75/dia. A temperatura de 29,3 °C determinou as maiores proporções da EMI destinadas para as retenções de energia bruta (EB), proteína bruta (PB) e gordura bruta (EE). No experimento 2, a média de temperatura de 24,6 °C melhorou os índices de desempenho para a idade de 8 a 14 dias, assim, a média da exigência de mantença foi estimada em 238 kcal/kg de PV0,75/dia. A temperatura em que as maiores proporções da EMI foram destinadas para as retenções de EB e PB foi próxima a 26,4 °C. No experimento 3 foi observado que, apesar de ter piorado a conversão alimentar, as temperaturas entre 22,6 e 24 °C até os 14 dias de idade se mostraram mais favoráveis para o desempenho produtivo e rendimentos de corte dos frangos aos 39 dias. Os resultados demonstraram também que, frangos que receberam temperatura mais baixa até os 14 dias e em função disso apresentavam menor desempenho, demonstraram uma tendência de recuperação ascendente do desempenho, até os 39 dias. Concluí-se por estes resultados que, frangos de idades pré-iniciais e iniciais modificam as suas exigências de energia para mantença em função da modificação do ambiente térmico, influenciando no seu desenvolvimento inicial com reflexos na idade de abate.Two experiments were performed to assess the effect of temperature and the temperature and umidity index (TUI) in the pre-starting and starting age of broilers on changes caused in partitions of metabolizable energy intake (MEI) and maintenance (MEm) requirements and performance. A third experiment measured the subsequent performance of chickens that were subjected to different temperatures during the first 14 days of life, as well as the composition and yield of carcass and cuts. In experiments 1 and 2 was determined to metabolizable energy (ME) using chromium oxide indicator, and the results of the partitions of the MEI have been determined from the slaughtered comparative technique for each evaluated period. The performance was also evaluated. The results of animal response variables were subjected to regression analysis with independent variables temperature averages and the TUI. The results determine in experiment 1 that, for the age of 1 to 7 days the average temperature of 28.3°C improved levels of performance. The maintenance requirement for metabolic weight at this age showed lower value in 30.8°C, being estimated at 163.7 kcal/kg BW0,75/dia. 29.3°C temperature determined the highest proportions of MEI for the retention of gross energy (GE), crude protein (CP) and crude fat (CF). In experiment 2, the mean temperature of 24.6°C improved levels of performance on 7 to 14 days, so the average maintenance requirement was estimated at 238 kcal/kg BW0.75/day. The temperature at which the highest proportions of MEI were intended for the retention of GE and CP was next to 26.4°C. In experiment 3 was observed that, in spite of having worsened the feed conversion, temperatures between 22.6 and 24° C until the 14 days of age were more favorable for the productive performance and cutting income of chickens to 39 days. In experiment 3 was observed temperatures between 22.6 and 24° C until the 14 days of age were more favorable for the productive performance and yield of chickens to 39 days. The results showed that chickens that received lower temperature until the 14 days and because of this had less performance, showed a trend of rising performance recovery, until the 39 days. It was concluded that chickens for ages pré-iniciais and initials modify their energy requirements for maintenance depending on the modification of the thermal environment, influencing in early development with reflections in the age of slaughter

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.
