No full textDiffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Impactos da pesquisa sobre duas cadeias de erva-mate na região do Alto Uruguai Rio-Grandense.
No full textO presente trabalho têm por objetivo avaliar o impacto sócio-econômico de pesquisas desenvolvidas através da parceria da Universidade Regional Integrada do Alto Uruguai (URI) e a Embrapa Florestas em duas cadeias agroindustriais de erva-mate (municípios de Áurea e Machadinho), na região do Alto Uruguai Rio-grandense. Para a realização desta pesquisa fez-se uso, principalmente, de dados secundários (banco de dados SIDRA e IBGE), dados primários levantados diretamente junto aos produtores rurais, empresas de comercialização de insumos e indústrias ervateiras. As principais conclusões indicam que: a) a inovação tecnológica surte um melhor resultado quando esta estiver associada a organização dos produtores; b) os esforços desenvolvidos pelas instituições envolvidas nos projetos, bem como o esforço da Secretaria de Ciência e Tecnologia do Estado do Rio Grande do Sul apresentaram aumento da renda em todos os grupos de produtores, como sob os aspectos de tendência a migração e adoção tecnológica e c) a capacidade de sinergia entre os parceiros otimiza o uso de recursos (financeiros e humanos) públicos e privados.Seção: Economia e Mercado.

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
