Molibdênio e cálcio via semente no desenvolvimento, nodulação e produção de sementes de soja
No full textEste trabalho teve como objetivo avaliar os efeitos do tratamento de sementes de quatro variedades de soja com quatro doses de molibdênio na presença e ausência de cálcio, sobre a nodulação, desenvolvimento das plantas e produção de sementes. O trabalho foi conduzido em área experimental da Faculdade de Engenharia de Ilha Solteira - UNESP, no município de Selvíria - MS. Avaliaram-se as populações inicial e final de plantas; número de nódulos; massa seca dos nódulos, massa seca da parte aérea e das raízes; altura de plantas; número de vagens; número de sementes por planta e por vagem; massa de cem sementes e produtividade de sementes. Observou-se incremento na população inicial quando foi adicionado cálcio via sementes; a produção de massa seca da parte aérea foi influenciada pelos níveis de adubação com molibdênio, sendo a dose mais adequada para obtenção da máxima produtividade de 124,3 g ha-1; A produtividade de sementes respondeu de maneira linear crescente às doses de Mo utilizadas via semente; Não foi observado efeito das doses de Ca e Mo sobre a nodulação das plantas; Recomenda-se o plantio da variedade Vencedora com 225 g ha-1 de Mo via semente e sem utilização de Ca.This work objectived to evaluate the seed treatment effect of four soybean varieties with four rates of molybdenum with or without calcium on the nodulation, plant development and seed production. The work was carried out at experimental area from Faculdade de Engenharia de Ilha Solteira - UNESP, Selvíria - MS. Were evaluated initial and final plant population; number of nodules, dry mass of nodules, dry mass of aerial part and dry mass of roots; plant height; number of pods; number of seeds per plant and per pod; 100 seeds mass and seed yield. There was increase in the initial plant density when was added calcium in the seeds; the aerial part dry mass showed response to the Mo levels, with the 124,3 g ha-1 of Mo the more adjusted level for attainment of the maximum productivity; The seed yield showed linear increasing to the used Mo levels; It was not observed effect of the doses of Ca and Mo on the plants nodulation; Is recommended to cultivate the Vencedora variety with the rate of 225 g ha-1 of Mo without Ca.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

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
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
