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
O papel da agricultura e do trabalho não agrícola na reprodução socioeconômica de famílias quilombolas na Serra dos Tapes, Rio Grande do Sul : um olhar sobre perspectivas de desenvolvimento local
Full text linkEsta dissertação de mestrado tem como objetivo compreender a organização social, econômica e produtiva na comunidade remanescente de quilombo Alto do Caixão, localizada na região da Serra dos Tapes, no município de Pelotas/RS. Para tanto, busca-se entender como suas famílias, em interação com o contexto regional, mobilizam diferentes recursos para garantir sua reprodução socioeconômica em escala local. A partir desta compreensão, pretende-se, também, evidenciar as perspectivas de desenvolvimento para a comunidade. A fim de alcançar os objetivos propostos neste estudo, adotou-se a perspectiva analítica de Sistemas Agrários, ferramenta que possibilitou identificar as principais formas de agricultura praticadas na Serra dos Tapes, assim como suas transformações histórico-geográficas. Além disso, a mesma abordagem proporcionou os instrumentos necessários para delinear e analisar os sistemas sociais e de produção das famílias quilombolas e sua relação com o cenário regional no qual encontram-se inseridas. Por meio do estudo de campo e da leitura dos resultados obtidos, foi possível entender a importância do trabalho não agrícola para a reprodução socioeconômica das famílias. A agricultura, por sua vez, apresenta um caráter complementar à renda, assumindo significativa importância na construção da identidade, na segurança e autonomia alimentar das famílias.This master's thesis aims to understand the social, economic and productive organization in the remnant of Quilombo community of Alto do Caixão, located in Serra dos Tapes region, in the municipality of Pelotas/RS. In order to do so, it seeks to understand how their families, in interaction with the regional context, mobilize different resources in order to guarantee their socioeconomic reproduction on a local scale. From this understanding, it is also intended to highlight the perspectives of development for the community. In order to reach the objectives proposed in this study, we adopted the analytical perspective of Agrarian Systems, a tool that allowed us to identify the main forms of agriculture practiced in Serra dos Tapes, as well as their historical-geographic changes. In addition, the same approach provided the needed instruments to trace and analyze the social and production systems of quilombola families and their relation to the regional scenario in which they are inserted. Through the field study and the reading of the results, it was possible to understand the relevance of non-agricultural work for the socioeconomic reproduction of the families. Agriculture, on the other hand, presents a complementary character to the family income, assuming significant importance in the construction of the identity, in the food security and autonomy of the families
Geografias quilombolas e experiências de articulação política no sul do Rio Grande do Sul
Full text linkThis work addresses the political dimension of quilombola geographies in the far south of Brazil. Drawing on the experiences and testimonies of members of the Alto do Caixão quilombo, I analyze the political organization within the community, considering both the quilombolas\u27 engagement in the political-institutional sphere and their everyday experiences in their territories. These experiences are particularly characterized by survival strategies and the development of life technologies and spatial knowledge in response to the racial hierarchies, territorial inequalities, and specific socioeconomic disparities in the southern region of Rio Grande do Sul. Through this analysis, I argue that these experiences constitute a Black radical politics that reveals a distinctive geography, where the spaces of life, knowledge, solidarity, and interrelationship networks built by these individuals shape the collective conception and construction of quilombola territories.Este trabajo aborda la dimensión política de las geografías quilombolas en el extremo sur de Brasil. A partir de las experiencias y relatos de los miembros del quilombo Alto do Caixão, analizo la articulación política en la comunidad, considerando tanto la participación de los quilombolas en el campo político-institucional, como las vivencias cotidianas en sus territorios, marcadas particularmente por estrategias de supervivencia y por el desarrollo de tecnologías de vida y conocimiento espacial frente a las jerarquías raciales, desigualdades territoriales y socioeconómicas específicas de la región sur de Rio Grande do Sul. A partir de esto, busco argumentar que estas experiencias constituyen una política radical negra que revela una geografía propia, en la que los espacios de vida, los saberes, la solidaridad y las redes de interrelación construidas por estos sujetos influyen en la concepción y construcción colectiva de los territorios quilombolas.Este trabalho aborda a dimensão política das geografias quilombolas no extremo sul do Brasil.

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
