This piece of research aims at analyzing the absolute and relative co-citation indicators, especially Salton’s Cosine and comparing the contribution of these indicators to the understanding of a domain, applying them to the universe of "Metric Studies" at the BRAPCI base. It also aims at presenting the co-citation network generated from the absolute frequencies and highlighting the groupings of co-cited authors, depending on the relative values, integrating and explaining the information from the two indexes. The domain analysis, by means of its 11 approaches, including “Bibliometric Studies”, focuses on the science characterization and evaluation, in that it allows us to identify and to analyze the conditions under which the scientific knowledge is constructed and socialized. In these studies, the contribution of citation and co-citation analysis is highlighted. Of the total of 147 articles retrieved at BRAPCI base, the authors cited in at least 11 articles, in a total of 38 researchers, were selected. The 38 x 38 symmetric matrix with the absolute frequencies of co-citation and the matrix with the relative values of Salton’s Cosine were generated. The co-citation network with absolute frequency values were constructed, through Ucinet software. Cluster analysis of data with relative values wer performed, using the SPSS software. Significant differences between the absolute and relative indexes, with some high absolute values of co-citation were observed; when considered in relation to the presence of each author, their significance is decreased. As to the generated network, seven groups were determined, in which only one is established for close themes and comes from co-citations in the original sense of the term. Five groups present closeness in absolute and relative indicators. It can be concluded about the importance of the studies of authors' co-citation analysis, which associate the two indexes, absolute and relative, in order to visualize and understand the underlying structures of a scientific domain.

Subject Cataloging is one of the processes of subject approach to information, beside indexing and subject analysis. In this sense, this research is a part of a broader project which analyses ISKO as an academic space that promotes a dialogical dimension among those theoretical questions. In this sense, it aims to analyze the presence of subject cataloguing in the discussions of knowledge organization as well as how the authors of such subject dialogue each other. Considering the questions, the full collection of ISKO and ISKO-Spain conference proceedings were analyzed in order to verify how present were subject cataloguing matters in those collections. It was possible to identify a group of 36 articles (27 from International ISKO and 9 from ISKO – Spain) whose references were bibliometrically analyzed in terms of documentary forms, average life, language and citation analysis. The results showed that the major ISKO and ISKO-Spain literature on subject cataloguing is based on journal articles, mostly published in English, presenting a relatively young average life (14 years for ISKO and 10 for ISKO-Spain).

The São Francisco river delta is an important sedimentation environment located between the States of Sergipe and Alagoas. Due to a set of factors (physical processes and anthropic interference), a process of coastal erosion is currently happening quickly in their mouth. The sedimentation dynamics and coastal erosion in São Francisco river mouth and the reasons for the process of erosion is occurring quickly were the elements of study in this work. For that, were analyzed rainfall historical data series and river flow, sediment contribution data, to examine aerial photos and satellite images, besides the use of the bibliography on the matter. The analyses made served as a basis to understand how the process is happening and to verify how the anthropic interference is contributing to the occurrence of accelerated erosion on the spot.

This study proposes, based on Halliday (1985) and Raible (1992, 2001), that the interpropositional patterns of assim are distributed in continuum, which is set among the representative usages of different types of interdependency, starting from the examples of domination relations of parataxis up to the examples of hypotatics, passing through the ones that are between the poles of the continuum. We will exemplify this paperwork starting from the functioning of the phrase assim que, describing its syntactic and semantic behavior in the selected corpus and in an evidence analysis of the linguistic changing process through grammaticalization, which infers its functioning as a secular connector in order to indicate its position held by this pattern in the continuum.
