Orientador : Prof. Dr. Francisco MendonçaDissertação (mestrado) - Universidade Federal do Paraná, Setor de Ciencias da Terra, Programa de Pós-Graduaçao em Geografia. Defesa: Curitiba, 06/05/2010Bibliografia: fls. 120-128Resumo: O estudo apresentado procura realizar um levantamento sobre os diferentes tipos de discursos ambientais na Geografia Brasileira. A Geografia como sendo uma ciência que estuda a relação espacial entre sociedade e natureza, teve incorporado a sua abordagem mais moderna os estudos sobre meio ambiente. Dentre a temática da pesquisa apresentada, o objetivo foi realizar uma identificação dos aspectos do discurso ambiental presentes historicamente na Geografia Brasileira, através da sistematização de artigos desta Revista Brasileira de Geografia (compreendendo o período entre 1941 e 2005). Supostamente a Geografia, quando vista como ciência da sociedade e/ou da natureza, passa por uma renovação no que diz respeito aos estudos sobre meio ambiente; a partir da segunda metade do século XX grande parte dos estudos da Geografia destinavam-se aos estudos da sociedade e dos Recursos Naturais; apesar das discussões anteriores, a Geografia Ambiental ganha corpo a partir dos anos de 1990 com a difusão das geotecnologias e a intensificação da preocupação global com o meio ambiente. Portanto procurou-se a realização de um resgate histórico e epistemológico da questão ambiental na Geografia Brasileira, através de métodos vindos da Análise do Discurso, pode-se fazer uma leitura das diferentes formas de abordagem de meio ambiente na Geografia.Abstract: This study tried to survey the different types of environmental discourses in the Brazilian Geography. Geography as a science that studies the spatial relationship between society and nature, had built his ore modern approach to studies on the environment. Among the themes of the research presented, the goal was to perform an identification of aspects of environmental discourse historically present in the Brazilian Geography through the systematization of this Brazilian Journal of Geography (including the period between 1941 and 2005). Supposedly the geography, when viewed as a science of society and / or nature, goes through a renewal with respect to studies on the environment, since the second half of the twentieth century most studies of geography were for studies of Society and Natural Resources, despite the earlier discussions, the Environmental Geography is formed from the early 1990s with the dissemination of geo-technologies and the intensification of global concern with the environment. So, sought the realization of historical and epistemological review of environmental issue in Brazilian Geography, coming through methods of discourse analysis, can make a reading of the different ways to approach of the environment in Geography
Propósitos geográficos no campo ambiental : fragamentos da geografia francesa e da geografia brasileira

Na Geografia o termo meio ambiente passou a ganhar destaque nas pesquisas a partir da década de 1970, sendo que seus significados aparecem de maneiras diferenciadas (polissemia). Ao consideramos a realização de uma investigação que revelasse os diferentes discursos no qual o termo meio ambiente se insere para Geografia brasileira, entendemos que seria enriquecedora a possibilidade de construir uma análise comparada, que ponderasse os intercâmbios científicos e a mundialização do capital científico. Posto isso, recordamos que a Geografia acadêmica brasileira havia recebido uma importante contribuição da Geografia francesa desde o momento de sua institucionalização, assim acreditamos ser adequado elegê-la para realização de um contraponto. Para Geografia francesa a polissemia do termo meio ambiente é ainda mais complexa, pois em língua francesa existem os termos milieu ambiant e
environnement (aparentemente com o mesmo significado). Desta forma, buscando amparar nossa tese, de que haveriam grandes influências da Geografia francesa no discurso ambiental da Geografia brasileira nos baseamos na teoria dos campos de Pierre Bourdieu e procuramos identificar as práticas discursivas na Geografia francesa e na Geografia brasileira que sustentassem a hipótese da existência de um campo ambiental na Geografia. Para tal, nosso objeto de análise foram textos extraídos de três importantes periódicos científicos: Annales de Géographie, Revista Brasileira de Geografia e Boletim Paulista de Geografia, sendo ao total 127 artigos analisados, que foram agrupados de acordo com suas práticas discursivas em relação ao meio ambiente. Assim, constatamos a existência de um campo ambiental na Geografia, também pudemos mapear diferenciações e similaridades nos usos dos termos em francês e português, bem como, constatamos como o interesse das instituições permeiam as atividades científicas e o alcance da mundialização do capital científico na composição do campo ambiental na Geografia.Abstract: The scientific language is the mechanism by which scientific communication can be performed, that is through a set of specific terms (concepts) that can carry out scientific communication. In geography the term environment began to gain prominence in the research from the 1970s, and their meanings appear different ways (polysemy). To consider carrying out an investigation to reveal the different discourses in which the term environment falls to Brazilian Geography, we believe it would be enriching the possibility of building a comparative analysis, to consider the scientific exchanges and the globalization of scientific capital. We remember that the Brazilian academic Geography had received an important contribution of the French Geography from the moment of its institutionalization, so we believe it is appropriate to elect the French geography to perform a counterpoint. For French Geography, the polysemy of the term environment is even more complex, since in French there are two terms milieu ambiant and environnement (apparently with the same meaning). Thus seeking support for our thesis that there would be major influences of the French Geography in environmental discourse of the Brazilian Geography, we rely on the field's theory of Pierre Bourdieu and we seek to the identify the discursive practices in the French Geography and Brazilian Geography that supported the hypothesis of the existence of an environmental field in the Geography. To this end, our object of analysis were extracted texts of three important scientific journals: Annales de Géographie, Revista Brasileira de Geografia and Boletim Paulista de Geografia, in total were analyzed 127 articles, which they were grouped according to their discursive practices in relation to the environment. Thus we find the existence of an environmental field in the Geography, we also map differences and similarities in the use of the terms in French and Portuguese as well, we see how the interest of the institutions permeate the scientific activities and the scope of internationalization of scientific capital in the composition the environmental field in the Geography
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
