Get PDFDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias. Programa de Pós-Graduação em Agroecossistemas.Este trabalho tem como objetivo principal, identificar e caracterizar os agentes de mercado da Ceasa/SJ, bem como conhecer e analisar as relações entre eles. A pesquisa de campo foi realizada na unidade de São José da Ceasa/SC, a qual atende a demanda por produtos hortifrutigranjeiros da região da grande Florianópolis. Para tanto se realizou uma pesquisa de caráter exploratório e descritivo, no período de novembro de 2005 a janeiro de 2006, utilizando como instrumento de investigação uma entrevista semi-estruturada. A definição dos entrevistados da pesquisa teve origem no Cadastro Geral de Usuários da Ceasa/SC, atualizado no segundo semestre de 2005, contabilizando 679 agentes de mercado. Estes foram estratificados em três categorias, sendo entrevistados um total de cinqüenta e nove agentes de mercado, sendo: seis atacadistas, doze agricultores comerciantes e quarenta e um agricultores. Os resultados da pesquisa permitiram identificar o perfil dos agentes de mercado: atacadista, agricultor comerciante e agricultor, sua condição enquanto produtor ou comerciante, caracterização da produção, da comercialização e sua participação no mercado atacadista de hortifrutigranjeiros na Ceasa/SJ. Procurou-se identificar também os canais de comercialização e as estratégias utilizadas pelos agentes de mercado, as relações existentes entre os atores, identificando os principais interlocutores na comercialização e formas de negociações destes agentes. Verificaram-se também os volumes negociados, faturamento, grau de satisfação e entendimento do mercado, especialmente da sistemática de formação de preços e as perspectivas em relação a este espaço de mercado e seu futuro. Constatou-se que todos os agentes entrevistados ampliaram a renda familiar com as atividades comerciais na Ceasa/SJ e pretendem continuar operando na mesma. A análise dos resultados revelou que a Ceasa/SJ tem se mostrado um espaço diferenciado para a comercialização da produção dos agricultores usuários da mesma, especialmente por permitir negociação presencial entre agricultores e compradores, responsáveis por 88% dos negócios dos agricultores na central.This work aims identifying and characterizing the market agents of Ceasa/SJ, as well as to know and to analyze the relationships between these. The field research was accomplished in the unit of Ceasa/SC- São José, which assists the demand for fruits and greens vegetable products in the region of great Florianópolis. In order to achieve those goals, a research of exploratory and descriptive characteristic took place, from November 2005 to January 2006, using as instrument of investigation a semi-structured interview. The definition of the interviewees of this research came form the General Survey of Users of Ceasa/SC, updated in the second semester of 2005, accounting 679 market agents. These were stratified into three categories: wholesalers, merchant farmer and farmer. A total of fifty nine market agents were interviewed, among them, six wholesalers, twelve merchant farmers and forty one farmers. The results of this research allowed the identification of the 3 market agents' profile (wholesaler, farmer merchant and farmer), their condition while producer or merchant, characterization of the production, the commercialization and their participation in the wholesale market of fruits and green vegetable at Ceasa/SJ. This work also aimed identification the commercialization channels, the strategies used by the market agents, the existing relationships between the actors, identifying the principal speakers and forms of commercialization of these agents. It was also identified the negotiated volumes, revenue, satisfaction degree and understanding of the market, especially of the systematic of prices definition and the perspectives in relation to this market space and its future. It was verified that all agents interviewed enlarged the family income with the commercial activities at Ceasa/SJ and they intend to continue operating in the same way. The analysis of the results revealed that Ceasa/SJ has been showing if a differentiated space for the commercialization of the farmers' users of the Ceasa/SJ, especially for allowing to present negotiation between farmers and buyers, responsible for 88% of the farmers' businesses in the headquarters
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
