Implications for the Consideration of References Instead of Citations for Bib...Teresa Silio Martinez
INTRODUCTION: Citation indexes are produced by counting de-contextualised citations, which result from the transformation of references into citations, generating two different objects -two different signs-. This causes an ambiguity of both signs which is relevant for citation indexes and for science evaluation. METHODOLOGY: Two methods were used: 1) Qualitatively: It is performed a semiotic analysis in order to distinguish between bibliographic references and citations in terms of electronic reference linking. Quantitatively: Citations and references were counted within a relevant sample of papers from different scientific disciplines. RESULTS: Tthe number of bibliographic references is higher than the number of citations in the 100 % of the sample articles analysed. In many cases, the number of references is twice as the number of citations. The 30,1 % of the citations were referenced several times, for were counted just once. DISCUSSION: By considering references instead of citations, the following bibliometric laws and indicators are affected,: Bradford / De Solla’s law, direct academic journal citations, bibliographic coupling, co-citation, impact factor and h-index. A semiotic ambiguity between references and citations causes a relevant error in science evaluation that can be avoided by the use of electronic reference linking.

CPBR7 - Pensamento Visual e PrototipagemNei Grando
A palestra ocorreu no dia 30/1 às 10 horas no palco Hypatia (sobre Empreendedorismo e Inovação). Antes de desenvolver um produto, serviço ou solução - o uso de Pensamento Visual e de Protótipos são fundamentais para expor idéias, conceitos, informações e facilitar a comunicação e o entendimento por todos os interessados.
