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
Efeito do uso do pó de rocha em SPDH de brócolis e couve-flor sobre os atributos químicos do solo e produtividade das culturas
Full text linkTCC (graduação) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias, Agronomia.O presente trabalho objetivou caracterizar a eficiência do pó da rocha olivina melilitito e seu
potencial de disponibilizar os nutrientes em solo manejado em SPDH, bem como a
produtividade das culturas, brócolis e couve-flor. O experimento foi conduzido em uma
propriedade localizada no município de Angelina-SC com histórico de nove anos de
produção hortaliças sob Sistema de Plantio Direto de Hortaliças. Os tratamentos utilizados
foram: testemunha sem adubação (T1); 5 Mg ha-1
de pó de rocha (T2); 10 Mg ha-1
de pó de
rocha (T3); 20 Mg ha-1
de pó de rocha (T4); adubação mineral com NPK (T5). Ao longo de
três cultivos com hortaliças em rotação de plantas de cobertura com aplicação de pó de rocha
no início de cada ciclo no momento do transplante das mudas. Foram coletadas amostras de
solo nas profundidades de 0-10 e 10-20 cm para posterior avaliação dos atributos químicos
do solo: pH, Al, H+Al, Ca, Mg, K, P, e cálculo da CTCpH7,0 (T) e da saturação por bases
(V%). Nos mesmos tratamentos foram coletadas plantas que possuíam formação de
inflorescência para se determinar a produtividade. A aplicação do pó de rocha se mostrou
efetiva para os atributos químicos como pHH2O na camada 0-10 cm nos três ciclos, como T3
e T4 apresentando os maiores valores no terceiro ciclo. O Ca apresentou diferença entre
tratamentos na camada de 10-20 cm no primeiro cultivo no terceiro ciclo e na camada 0-10
e 10-20 cm. O teor de P obteve diferença na camada de 0-10 cm no segundo e terceiro ciclo,
no primeiro ciclo houve diferença entre tratamentos na camada 0-10 cm e para o K foi
possível observar diferença apenas no terceiro ciclo na camada 0-10 cm, podendo afirmar
que a longo prazo o seu uso pode promover melhorias nos atributos químicos do solo. Não
houve diferença entre os tratamentos para a produtividade de brócolis e couve-flor não foi
influenciada pelo pó de rocha. Com base nos resultados, é preciso realizar mais avaliações com cultivos de uma mesma cultura para se obter efeitos na produtividade com o uso do pó
de rocha.The present work aimed to characterize the efficiency of the olivine melilithite rock powder
and its potential for nutrient supply and productivity for two vegetables (broccoli and
cauliflower) and for nutrient availability in soil managed under SPDH. The experiment was
conducted on a farm located in the municipality of Angelina-SC with a nine-year history of
vegetable production under no-till farming system. Over three vegetable crops and
succession of cover crops with rock powder applications, soil samples were collected at 0-
10 and 10-20 cm depths for further evaluation of chemical attributes such as pH, Al, H+Al,
Ca, Mg, K, P, CTCpH7.0 (T) and base saturation (V%). In the same treatments, plants with
head formation (flower buds) were collected to obtain productivity. The application of rock
powder was effective for chemical attributes such as pHH2O in the 0-10 cm layer in the
three cycles, with T3 and T4 showing the highest values in the third cycle. The Ca showed
a difference between treatments in the 10-20 cm layer in the first cultivation in the third cycle
and in the 0-10 and 10-20 cm layers. The P content showed a difference in the 0-10 cm layer
in the second and third cycle, in the first cycle there was a difference between treatments in
the 0-10 cm layer and for K it was possible to observe a difference only in the third cycle in
the 0-10 cm layer. There was no difference between treatments for broccoli and cauliflower
productivity was not influenced by rock powder.

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.
