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
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
O Meio Subterrâneo Superficial e a conectividade biológica no sistema ferrífero de Carajás
Get PDFTese (doutorado) — Universidade de Brasília, Programa em Rede Multi-Institucional do Pró-Centro-Oeste de Pós-Graduação em Biotecnologia e Biodiversidade, 2023.Baseado na amostragem da fauna subterrânea de artrópodes que ocupa os vazios da matriz
rochosa que envolve as cavernas, o chamado Meio Subterrâneo Superficial (MSS), este
trabalho teve como objetivo geral descrever o papel do MSS na dispersão da fauna
subterrânea na formação ferrífera de Carajás. Para descrever a estrutura da comunidade e
os padrões de distribuição de artrópodes do MSS de acordo com o tipo de isca utilizado,
a profundidade e a sazonalidade climática na Formação Ferrífera de Carajás, a
metodologia aplicada baseou-se na instalação de armadilhas em furos de sondagem a fim
de amostrar os animais que estão transitando pelas descontinuidades do MSS de acordo
com tipo de isca utilizada, profundidade e sazonalidade climática. A amostragem total de
artrópodes subterrâneos resultou na coleta de 63 táxons. O tipo de isca influenciou
significativamente a comunidade de aranha e ácaros, a profundidade apresentou relação
significativa com a riqueza da fauna total, bem como outros grupos como Arane e
Colembolla. Por sua vez, a sazonalidade climática afetou significativamente, ácaros,
dípteras e coleópteras, devido à variação nos índices pluviométricos, mas principalmente
à variação na proporção da zona vadosa e zona saturada no maciço. A riqueza e
composição de espécies foram afetadas significativamente pelas três variáveis analisadas.
As médias da riqueza e composição de espécies das amostras entre os furos de sondagem
não evidenciaram a formação de agrupamentos, indicando uma ausência de estruturação
da comunidade de artrópodes do platô analisado. A fim de analisar a estruturação genética
entre diferentes cavernas na Formação Ferrífera Carajás foram coletadas amostras de
Pseudoporatia sp. (Diplopoda: Pyrgodesmidae) encontradas comumente em cavernas ao
longo da paisagem. Seu material genético foi extraído e hierarquizado, a fim de observar
a existências de populações estruturadas ou até espécies crípticas. A análise filogenética
de Pseudoporatia sp. foi realizada com base em 198 sequências do gene mitocondrial
Cictocromo Oxidase I - COI. Baseado no mapa de haplótipos e no número de mutações
observadas entre as populações foi possível verificar que o morfótipo estudado apresenta
pouca ou nenhuma estruturação genética populacional dentro de um mesmo platô ou
serra, contudo, de forma contrária, foi possível observar que as populações de áreas
disjuntas podem ser compostas por um pool de espécies crípticas morfologicamente
relacionadas, mas geneticamente diferentes. Estes resultados sugerem a conectividade
biológica subterrânea em platôs contínuos e demonstram a necessidade de considerar o
MSS nos levantamentos faunísticos na compatibilização da conservação da fauna
subterrânea e o desenvolvimento de atividades minerárias na Floresta Nacional de Carajás
a fim de evitar a perda liquida de espécies.Based on sampling the subterranean fauna of arthropods that occupy the voids in the rock
matrix that surrounds the caves, the so-called Superficial Subterranean Environment
(MSS), this work had the general objective of describing the role of the MSS in the
dispersion of subterranean fauna in the Carajás iron formation. To describe the
community structure and distribution patterns of MSS arthropods according to the type
of bait used, depth and climatic seasonality in the Carajás Iron Formation, the
methodology applied based on the installation of traps in drilling holes at in order to
sample animals that are transiting through the MSS discontinuities according to the type
of bait used, depth and climatic seasonality. A total sampling of arthropods selected from
the collection of 63 taxa. The kind of bait significantly influenced the Aachnida and Acari
community, the depth showed a significant relationship with the richness of the total
fauna, as well as other groups such as Arane and Colembolla. In turn, climatic seasonality
significantly affected mites, diptera and coleoptera, due to the variation in rainfall rates,
but mainly to the variation in the proportion of the vada zone and saturated zone in the
massif. Species richness and composition were significantly affected by the three
variations observed. The species richness and composition media of the samples between
the drilling holes did not show the formation of clusters, reducing the lack of structure in
the arthropod community on the consolidated plateau. In order to analyze the genetic
structure between Pseudoporatia sp. from different caves in the Carajás Iron Formation,
samples of Pseudoporatia sp. (Diplopoda: Pyrgodesmidae) commonly found in caves
throughout the landscape. Its genetic material was extracted and hierarchized, in order to
observe the existence of structured populations or even cryptic species. The phylogenetic
analysis of Pseudoporatia sp. was carried out based on 198 sequences of mitochondrial
gene Cyclochrome Oxidase I - COI. Based on the haplotype map and the number of
mutations observed among populations, We notice the studied morphotype presents a
poor population genetic structure in the same plateau or mountain range. However, on the
other way, it was possible to observe that populations in separeted areas may be composed
of a pool of morphologically related but genetically different cryptic species. These
results corroborate the underground biological connectivity in continuous plateaus and
demonstrate the need to consider the MSS in faunal surveys to make the conservation of
underground fauna compatible with the development of mining activities in the Carajás
National Forest in order to avoid the loss of species.Instituto de Ciências Biológicas (IB)Programa de Pós-Graduação em Biotecnologia e Biodiversidade (Rede PRÓ-CENTRO-OESTE

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.
