Introduction: Authority records interchange requires establishing and using metadata standards, such as MARC 21 Format for Authority Data, format used by several cataloging agencies, and Metadata Authority Description Schema (MADS), that has received little attention and it is a little widespread standard among agencies. Purpose: Presenting an introductory study about Metadata Authority Description Schema (MADS). Methodology: Descriptive and exploratory bibliographic research. Results: The paper address the MADS creation context, its goals and its structure and key issues related to conversion of records from MARC 21 to MADS. Conclusions: The study concludes that, despite its limitations, MADS might be used to create simple authority records in Web environment and beyond libraries context.

Social representations are values and ideas shared and transmitted by a group of individuals. This article aims to investigate how researchers’ social representations can influence their analysis of an interview. Data were collected from 28 students participating in a course on interview analysis. Students were divided into three groups. Each group received the same excerpt of a transcript, but with different characterizations of the interviewee: for Group 1, it was a young man who had studied in a public school; for Group 2, the subject had attended a special education school for people with intellectual disabilities; for Group 3, he had studied at a private school. The three groups were asked to analyze the interview and submit a written document describing their analysis. The data revealed that the students carried out interpretive synthesis, descriptive synthesis, and thematic analysis. Interpretations of content data indicated that participants in Groups 1 and 3 attributed negative representations to the interviewee and/or to public or private school. In contrast, participants in Group 2, which was told that the interviewee had intellectual disabilities, attributed positive representations to the interviewee and to the special education school. The conclusion indicates the urgency for theoretical and practical training of young researchers regarding analysis of interviews so that the representations do not lead to biased results. The comparison of the results with an earlier similar study points to a probable change in representations of people with intellectual disabilities.

This article discusses the access to geographic information and its importance for the public policies formulation, reflecting on the implementation of the Spatial Data Infrastructure. The data view and the maps construction are useful for identifying needs and sponsoring public managers in decision making. The public policies implementation stages are optimized when the quantitative and qualitative information are integrated to the spatial phenomena relations. The improvement in the use of geographic information for decision making will be achieved when spatial data are efficiently generated in spatial data infrastructures.

The objective of this research is to analyze the scientific production about „Metric Studies‟. It was used the data base BRAPCI (data base of articles and journals in Information Science) to outline the authors and institutions that produced more. As research procedure it was analyzed the articles with the keywords that represent the area of metric studies such as: Bibliometric, Cientometric, Informetric, Webmetric and Patentometric between 1991 and 2011. It was analyzed the variable in study, building the collaborative network through the software Pajek. From these results, it was possible to delineate the tendencies presented in the scientific community on this subject from the data base BRAPCI.

Este artigo trata das grafias não convencionais da sílaba com coda nasal encontradasem textos escritos por jovens e adultos. Para a descrição desses dados de escrita, sãoconsideradas duas complexidades: (i) a fonético-fonológica da sílaba, particularmente doelemento nasal em coda, e (ii) a da representação ortográfica da nasalidade em português.Sob o aspecto fonético, a coda corresponde a uma redução de energia, o que pode tornar ossegmentos que preenchem essa posição da sílaba menos audíveis. Sob o aspecto fonológico,a coda pode ser vista como um constituinte não imediato da sílaba cujo preenchimento sofrerestrições. Sob o aspecto ortográfico, são três as possibilidades de registro da nasalidade:, como, respectivamente, em “campo”, “canto”, “maçã”. Argumenta-se que asgrafias não convencionais analisadas podem ser motivadas pelas características fonéticofonológicasdos enunciados falados (particularmente, da sílaba com coda nasal) e, também,pelas características das convenções ortográficas dos enunciados escritos (especificamente,as convenções para representação da nasalidade da coda). Defende-se que essas grafias nãosejam vistas como erros decorrentes da interferência da fala na escrita, mas como pistas darelação constitutiva dos enunciados falados e escritos.
