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
Climatology of the wind regime in Manaus from data Observed
No full textDue to its geographical location, Manaus is susceptible to light winds all year round. However, the occurrence of strong winds in a short space of time, known as gusts, which may or may not be associated with extreme precipitation, cause severe damage to the population, making it essential to forecast these events. With this in mind, the aim of this study was to analyze the records of gusts in Manaus, obtained from five automatic weather stations installed at different locations in the city, which make up the REMCLAM network. These data were initially subjected to quality control, developed in this study, and then analyzed in terms of spatial and temporal variability, as well as intensity. In the latter case, the percentile technique was applied to identify the threshold at which extreme gust events occur. Case studies were carried out to verify the behaviour of the variables wind direction, atmospheric pressure, relative humidity and air temperature in the moments prior to extreme events in order to identify a pattern and thus be able to help the agencies that act directly to minimize damage to the population due to natural phenomena, such as Civil Defence. With regard to the quality control of each station, a quantity of data was removed due to some kind of error and generated a new availability of data. The wind speed and gust distributions varied symmetrically and asymmetrically, with a difference in intensity between urban and rural areas. The most intense gusts on average occur mainly in the months of transition from dry to rainy season and rainy season. Their predominance varies from northeast to southeast depending on the rainy and dry seasons and transitions. Extreme gust events were identified using thresholds of 12.9 m/s and 8.1 m/s for urban and rural areas, respectively. Extreme gusts were up to 21.0 m/s (urban) and 17.6 m/s (rural), with greater frequency in January and October. These occurred predominantly between 10am and 5pm. Daily precipitation accumulations of up to 124 mm were associated with extreme gust events, which were also identified with the absence of rain at the same measurement location. In cases of very extreme gusts, air temperature and atmospheric pressure dropped up to an hour before the gust occurred. The direction varied abruptly, with no precipitation occurring on some days or even being seen starting up to 3 hours before the gust event with precipitation starting three hours before.
Translated with DeepL.com (free version)Em decorrência da sua localização geográfica, Manaus é suscetível a ventos fracos
durante todo o ano. No entanto, a ocorrência de ventos fortes em um curto espaço de
tempo, denominados de rajadas, que podem ou não ser associadas a precipitação
extrema, causam danos severos à população, tornando imprescindível a previsão
destes eventos. Neste sentido, o objetivo deste estudo foi analisar os registros de
rajadas em Manaus, obtidos através de cinco estações meteorológicas automáticas
instaladas em diferentes localidades da cidade as quais compõem a rede REMCLAM.
Estes dados foram, inicialmente, submetidos a um controle de qualidade,
desenvolvido neste estudo, e então analisados em temos de variabilidade espacial e
temporal, bem quanto à intensidade. Neste último caso foi aplicada a técnica dos
percentis para identificação do limiar a partir do qual tem-se os eventos extremos de
rajadas. Estudos de caso foram realizados para verificar o comportamento das
variáveis direção do vento, pressão atmosférica, umidade relativa e temperatura do ar
nos instantes anteriores aos eventos extremos visando identificar um padrão e assim
poder auxiliar os órgãos que atuam diretamente para minimizar os danos à população
por fenômenos naturais, como a Defesa Civil. Com relação ao controle de qualidade
de cada estação, uma quantidade de dados foi retirada em função de algum tipo de
erro e gerou uma nova disponibilidade de dados. As distribuições da velocidade do
vento e rajada variaram de forma simétrica e assimétrica, com diferença na
intensidade entre áreas urbana e rural. As rajadas mais intensas em média ocorrem
principalmente nos meses de transição de estação seca para chuvosa e estação
chuvosa. Sua predominância varia de nordeste a sudeste dependendo do período
chuvoso, seco e transições. Os eventos extremos de rajada, foram identificados
adotando-se os limiares de 12,9 m/s e 8,1 m/s para área urbana e rural,
respectivamente. As rajadas extremas foram de até 21,0 m/s (urbano) e 17,6 m/s
(rural), com maior frequência nos meses janeiro e outubro. Estas ocorreram
predominantemente no período das 10 às 17h. Acumulados diários de precipitação de
até 124 mm estiveram associados à eventos de rajadas extremas, às quais também
foram identificadas com a ausência de chuva no mesmo local de medida. Em casos
de rajada muito extrema a temperatura do ar e pressão atmosférica apresentaram
redução até uma hora antes da ocorrência da rajada. A direção variou bruscamente,
sem a ocorrência de precipitação em alguns dias ou até mesmo sendo verificados
tendo início até 3 horas antes do evento de rajada com precipitação iniciando três hora

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.
