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
A agroecologia no referencial curricular do Paraná : um olhar para os documentos norteadores do ensino fundamental anos finais na modalidade educação especial

No Brasil, os debates sobre o movimento orgânico iniciam no final da década de 70, por intermédio de iniciativas locais, porém, o mercado de orgânicos no Brasil começou a se fortalecer a partir do início dos anos 1990. Mas, na época não havia legislação brasileira para o setor. Foi a partir de 1994, em virtude de pressões internacionais, que iniciou-se o debate para a regulamentação da agricultura orgânica no país, sendo oficialmente reconhecida em maio de 1999. Todavia, apenas em 2003, quando foi instituída a Lei no 10.831, que o País teve um marco efetivo sobre a produção orgânica em âmbito interno e externo. Desde a regularização do setor, as legislações passaram por diversas alterações, estando em constante ajuste e revisão, o que representa um desafio, principalmente para os produtores, que precisam se adaptar as contínuas alterações nas regras. À vista disso, o presente estudo procurou trazer um panorama geral da agricultura orgânica no Brasil, com destaque às legislações sobre o tema, de modo a apresentar de forma mais acessível as principais modificações estabelecidas pelo mais recente regulamento técnico para sistemas orgânicos de produção, a Portaria do MAPA nº 52 de 15 de março de 2021, e avaliar quais as principais implicações decorrentes da nova regulamentação. O estudo identificou que dentre as várias alterações que a Portaria estabeleceu, a principal e com maiores implicações foi a que trata da obrigatoriedade da utilização de sementes e mudas orgânicas na produção vegetal. Mesmo com a atualização posterior pela Portaria nº 404, de 22 de fevereiro de 2022, que definiu o prazo de cinco anos, como período de adequação, para que as mudas de hortaliças obtidas a partir de sementes sejam oriundas de sistemas orgânicos de produção, essa realidade ainda parece muito distante, havendo pouquíssimos produtores de mudas orgânicas. Para que o cenário proposto pela Normativa se torne possível é necessário incentivos governamentais e apoio dos Institutos de Desenvolvimento, Pesquisa e Extensão de forma a alavancar o número de produtores de mudas e sementes, tal como a concepção de trabalhos e estudos visando obter mudas de qualidade. É importante destacar também que é necessário ponderação na determinação de uma obrigação dessa dimensão, a adoção de sementes e mudas orgânicas no Brasil deve acontecer pelos seus benefícios no sistema como um todo, de forma ordenada e projetada, contando com o apoio do governo, e não apenas por força da leiABSTRACT: Organic agriculture is a production model that aims economic, environmental and social sustainability of production systems, and has conquered each time some additional space, both on the consumer's meals and also on the production field. In Brazil, the debates concerning organic movement start at late 70's by local initiative, however, the organic market only started to grow stronger from the early 90's. But, by that time there was no Brazilian legislation for the sector. Starting from 1994, due to international pressure, the debate for the regulation of organic agriculture in the country began, being officially recognized on May, 1999. Still, it was only on 2003, when law number 10.831 was instituted, that the country reached an effective milestone on organic production, both internally and externally. Since the industry regulation, the legislation went through many modifications, being in constant review and adjustment, which represents a challenge, mainly for growers, who need to adapt themselves to the constant rule changes. Knowing this, the current study looked to bring a general outlook of agriculture in Brazil, highlighting the laws concerning the theme, so as to present in a more accessible way the main modifications issued by the most recent technical regulation for organic production systems, the Portaria do MAPA number 52, from March 15, 2021, and evaluate which are the main implications arising from the new regulations. The study has identified that, among the many changes that Portaria has stablished, the main and with greater implications was the one dealing with the mandatory use of organic seeds and seedlings in plant production. Even with the later update by Portaria number 404, from February 22, 2022, which defined a deadline of five years as the adaptation period so that vegetable seedlings obtained from seeds come from organic production systems, this reality still seems very far away, having very few organic seedling producers. To make the proposed scenario possible government incentives and support from Development, Research and Extension Institutes are needed in order to leverage the number of seedling and seed growers, as well as the conception of works and studies aiming to obtain high quality seedlings. It is important to highlight as well that is needed to ponder in determining an obligation of this dimension, the adoption of organic seeds and seedlings in Brazil must happen due to their benefits on the system as a whole, in an orderly and designed way, counting with government support, and not only by the force of the law[14]83 f. : il.

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.
