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
Identificação de regiões do cérebro para classificação de severidade do TEA utilizando Machine Learning e fMRI
Full text linkAutism Spectrum Disorder (ASD) is an age- and sex-related lifelong neurodevelopmental
disorder characterized primarily by social impairments. Current ASD prevalence indicates
that 1/59 children are diagnosed inside the spectrum. The Autism Diagnostic Observation
Schedule, Second Edition (ADOS-2) classifies ASD according to the disorder severity.
ADOS-2 classifies as ’autism’ cases that manifest more severe symptoms and as ’ASD
non-autism’ cases that exhibit milder symptoms. Many papers aimed to create algorithms
to diagnose ASD through Machine Learning (ML) and functional Magnetic Resonance
Images (fMRI). Such approaches evaluate the oxygen flow in the brain to classify the
subjects as ASD or typical development. However, most of these works, do not provided
information regarding the disorder severity. This paper aims to use ML and fMRI to
classify the disorder severity, aim to find brain regions potentially related to the disorder
severity. We used fMRI data of 202 subjects and their ADOS-2 scores available at the
ABIDE consortium to determine the correct ASD sub-class for each one. Our results
corroborate the initial hypothesis of functional differences within ASD, with some brain
regions where the functional difference was enough to create classification accuracy of 74%.
This paper has limitations regarding the total number of samples. However, it shows a
promising approach to ASD diagnosis.Agência 1O Transtorno do Espectro Autista (TEA) é uma condição neurológica vitalícia relacionada
à idade e ao sexo, caracterizada principalmente por disparidades sociais. A prevalência
atual do TEA indica que uma em cada 59 crianças estão dentro do espectro. O Autism
Diagnostic Observation Schedule, Second Edition (ADOS-2) é um processo de diagnóstico
que classifica o TEA de acordo com a gravidade do transtorno. ADOS-2 classifica
sintomas mais graves como casos de “autismo” e os que manifestam sintomas mais leves
como casos de “TEA não autista” (TEA-NA). Muitos artigos objetivam criar algoritmos
para diagnosticar TEA por meio de aprendizado de máquina (do inglês Machine Learning
- ML) e imagens de ressonância magnética funcional (do Inglês Functional Magnetic
Resonance Imaging - fMRI). Essas abordagens avaliam o fluxo de oxigênio no cérebro
para classificar os indivíduos como TEA ou com desenvolvimento típico. No entanto, em
geral, esses trabalhos não fornecem informações sobre a gravidade do transtorno. Esse
trabalho tem como objetivo a identificação de regiões do cérebro com diferença funcional
entre indivíduos TEA-NA e autistas, como possível biomarcador para a severidade das
características TEA. Para isso, o trabalho utilizou dados de fMRI de 202 indivíduos, e
suas respectivas pontuações ADOS-2 disponíveis no consórcio ABIDE para determinar a
subclasse de TEA correta para cada um. Esses dados foram utilizados para alimentar um
algoritmo de ML, de aprendizado supervisionado, o Support Vector Machine (SVC), de
forma a selecionar as regiões com maior diferença funcional para os indivíduos da amostra.
Os resultados corroboram a hipótese inicial de diferenças funcionais entre as subclasses de
TEA, com algumas regiões do cérebro onde a diferença funcional foi suficiente para criar
74% de precisão na classificação. Este trabalho apresenta limitações quanto ao número
total de amostras. No entanto, a abordagem mostra-se promissora para o diagnóstico de
severidade do TEA
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.
