Componentes de produção e qualidade do óleo de duas cultivares de gergelim em função da adubação orgânica e mineral em um neossolo flúvico
Get PDFIn the culture of sesame (Sesamum indicum L.) the average yield is around 650 kg ha 1
, but his production potential of 1,500 kg ha-1 with appropriate program of fertilization and
water availability. The objective of this experiment was to evaluate the influence of organic
and chemical fertilizers on yield components and oil quality of two cultivars of sesame: “BRS
Seda” and “CNPA G4”. The experiment was conducted on a family farm in Rosario town in
the municipality of Caxias, MA. The soil in the area is classified as Neossolo Flúvico. We
used the design in randomized blocks with 12 treatments in a factorial (6 x 2), being six
nitrogen sources: pies and cotton castor bean; cattle and goat manure, ammonium sulfate and
the witness, as well as two varieties of sesame: BRS Seda e CNPA G4 (BRS 196). There was
positive significant effect sources of fertilization on yield and sesame varieties on the growth
variables and weight of 1000 seeds. There was formation of four treatment groups, in the one
group, BRS Seda cultivar fertilized with goat manure excelled, showing better performance
on the characteristics of growth, production and productivity. Considering the increasing oil
yield, the goat manure can be recommended for varieties of sesame “BRS Seda” and “CNPA
G4”.Na cultura do gergelim (Sesamum indicum L.) o rendimento médio de grãos é em
torno de 650 kg ha-1
, porém o seu potencial produtivo é de 1.500 kg ha-1
com adequado
programa de adubação e disponibilidade hídrica. O objetivo deste experimento foi avaliar a
influência de adubos orgânicos e químicos nos componentes de produção e qualidade do óleo
de duas cultivares de gergelim: BRS Seda e CNPA G4. O experimento foi conduzido em
propriedade de agricultura familiar no povoado Rosário, no município de Caxias-MA. O solo
da área é classificado como Neossolo Flúvico. Utilizou-se o delineamento em blocos ao
acaso, com 12 tratamentos, em esquema fatorial (6 x 2), sendo seis fontes de nitrogênio: tortas
de algodão e de mamona; esterco bovino e caprino, sulfato de amônio e a testemunha, assim
como duas cultivares de gergelim: BRS Seda e CNPA G4 (BRS 196). Houve efeito
significativo positivo das fontes de adubação sobre a produtividade e das variedades de
gergelim sobre as variáveis de crescimento e massa de 1000 sementes. Verificou-se formação
de quatro grupos de tratamentos, no grupo 1, a cultivar BRS Seda adubada com esterco
caprino sobressaiu, apresentando melhor desempenho relativo às características de
crescimento, produção e produtividade. Considerando o aumento do rendimento de óleo, o
esterco caprino pode ser recomendável para as variedades de gergelim BRS Seda e CNPA G4
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

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.
