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
The Sinimbu Phase from Monte Castelo: technical and morphological variabitility
No full textO sambaqui Monte Castelo se encontra em São Francisco do Guaporé, no estado de Rondônia. O sítio apresenta datas para uma história inidígena que se inicia no Holoceno Médio e se mantém de maneira contínua ao longo de quase 6.000 anos. Assim, ele possui um alto potencial informativo para entendermos a história humana do Sudoeste Amazônico, possibilitando estudos zooarqueológicos, arqueobotânicos, funerários, entre outros. Até o momento, as pesquisas sobre cerâmicas no sítio focaram na Fase Bacabal, que possui datas antigas que alcançam 4.000 A.P. O sítio também apresenta a Fase Sinimbu, que alcança 5.800 A.P., uma tecnologia cerâmica diversa, que nos possibilita pensar as diferentes hipóteses sobre o surgimento desta tecnologia na América do Sul, a variedade de objetos que podem ser construídos a partir da argila e trazer informações importantes para o debate sobre cerâmicas antigas de maneira global. Esta dissertação busca descrever a Fase Sinimbu tecnológica e morfologicamente, a partir do teste com diferentes maneiras de analisar cerâmicas arqueológicas, que precisaram ser adaptadas e modificadas a partir do padrão de análise de cerâmicas amazônicas. Assim, pretende-se contribuir para o conhecimento de tecnologias de cerâmicas arqueológicas e para a construção de um contexto histórico entre 5.800 e 5.000 A.P. dentro de uma história indígena de longa duração.The Monte Castelo Shellmound is in São Francisco do Guarporé, in the state of Rondônia. The site has dates for a indigenous history that starts in the Middle Holocene and keeps continually for almost 6.000 years. It presents a highly informational potential to understand the human history of the Southwest Amazon, enabling studies of zooarchaeology, archaeobotany, funerary and others. To this moment, researches about the ceramics found at the site, focused on the Bacabal phase, which has old dates that reach 4.000 B.P. The site also presents the Sinimbu Phase, which reachs 5.800 A.P. and has a diverse ceramic technology that makes it possible to think the different hypotheses about the invention of this technology in South America, the variety of objects that can be made from clay and present important informations to the debate about early ceramics globally. This masters thesis intends to describe the Sinimbu Phase technologically and morphologically, using and testing different ways to analyze archaeological ceramics, that needed to be modified and adapted from a pattern of analyzing amazonian ceramics. Thus, it is intended to contribute to the knowledge about the technology of archaeological ceramics and to the construction of a historical context from 5.800 to 5.000 A.P., in an indigenous history in a long duration
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
