Information Science has for its object of study the general properties of information and analysis of their construction, communication and use processes. Organic information, one of the information types, is the one recorded in the archives, which can be split into two distinct groups based on users: current and permanent, used by administrators, historians/citizens, respectively. After defining the information behavior of each group, the articles directs the discussion to the mediation of information in the permanent archives. The interaction between user and information professionals through references services aiming the user needs is presented. In addition, the standards of archival description and the research instruments as tools to reference service are discussed. Moreover, it argues the importance of information technologies and the new possibilities for the promotion of organic information in permanent archives, especially concerning the information architecture of websites and the conversion of the DTD standards of archival descriptions.

The life expectancy increase has been augmenting studies on human aging. Among these studies are those that address the interaction between the elderly and the information and communication technologies, which may facilitate the execution of daily activities by elderly people. Therefore, the goal of this article was to investigate the application of constructivist elements in computer courses offered to Universidade Aberta à Terceira Idade – UNATI – UNESP – Campus of Marília, contributing to the digital inclusion of this community. The constructivist elements focused on the role of the teacher as a mediator in the teaching-learning process. It was found that most of these elements are already being applied in this universe, but some changes need to be undertaken in order to expand the opportunities for education and to allow students to have more autonomy for information seeking and use in the web environment.

Introduction: This paper presents preliminary results of the research project "Information access: actions and strategies of the Chamber of Deputies to meet 12.527/2011 Law”. Finally some considerations about the implementation of the Law within the Chamber of Deputies are presented. Objectives: Discuss the matter of public information access after the new Brazilian information access law and his relationship between the theories information policy, information regime and informational state. Methodology: Bibliographic research about several theoretical topics related to information access were raised, for example: the concept of information, information policy, informational state, information regime, electronic government and information asymmetry. Results: The preliminaries data shows a convergence of information policies from many countries, for example, Finland, Canada and South Africa, to a same point, which indicates an increase of transparency and a bigger active disclosure of information public. Conclusion: In Brazilian case, in the relationship between State and citizen, the new information access law means a materialization paradigm change or the concretization de other information regime. The sanction of this law can be interpreted as another step to increase the transparency and the affirmation of democratic relationship between State and society.

Presents a developing laboratory within History of Culture, subject taught in the Library and Archive Studies at UNESP (Marilia). The project is based upon the foundations of research line Information and Technology: students from the second under graduation year participate in the improving of 27 entries in Portuguese language Wikipedia. The aim is to capacitate for scientific reading and writing in digital media, habilitate for the information identification and recuperation and for the interpretation and understanding of formal and contents aspects and its reorganization. It includes activities of search, selection, remix and republishing of texts, images, audio and videos in the convergence of diverse hypertext information sources, supported by tutors with strategic abilities in digital environments. In this sense it was adhered to the international Wikipedia Foundation University Campus Ambassadors project. It’s also aimed to induce sharing and collaboration behaviors with the purpose of creating necessary habits for the informational empowerment in Brazil. As methodology is to optimize the work of individuals already trained in wiki culture and to create in within the subject information sharing programs with a more specialized bias, giving greater credibility to the digital environment. The environment syntaxes helps in the learning of the complementary skills of reading and writing and offers itself as an open repository from which information can be reused. It is, thus, an empowerment strategy in the search of autonomy and self reliance considering intersemiotic knowledge in the edition, visualization and understanding of information in the social web. A second step of a verifying research on the environment’s credibility after the consolidation and dissemination of the entries improvement work is proposed.

The usability and accessibility, when applied to digital information environments, provide ease of use and access to information, respectively. Thus, we aim to discuss these concepts and apply them in specific digital environments to the elderly through the documentary and bibliographic study of specific recommendations on projects for elderly users. This study was conducted in conjunction with students at the Universidade Aberta à Terceira Idade (UNATI) - UNESP - Marilia, who assisted in the classification of recommendations for usability and accessibility are essential (Priority 1), important (Priority 2) and optional (Priority 3). The results indicate the importance of this type of study for the digital and social inclusion of older people by facilitating elements of access and use of information, providing the building more inclusive informational architectures. The resulting recommendations can be used as a starting point for the design of digital environments for the elderly in a specific heuristic evaluation, for example. However, it remains important to the application of usability testing with users, including the application to validate these recommendations, since different contexts may arise from the implementation of different elements, resources and information services.

Analyzes the professional knowledge of the subject cataloger about the role of indexing policy in the context of university libraries. Therefore, the study consists of a questionnaire and sociocognitive analysis of the professional knowledge of three subject catalogers of different university libraries in the state of São Paulo / Brazil, through the application of Verbal Protocol Group. The results indicate that the subject’s cataloging must be supported by current standards and guidelines that address the specificities of each informational context and guide the daily practice. We conclude that the lack of guidelines aimed at standardizing and/or theoretical and methodological parameter of subject cataloging process is one of the main points to be observed by the specialized literature in Information Science.

It is proposed the search of teaching methodology with socio-cognitive approach to present teaching strategies that simulate the experience of professional context that is propitious to work out the tasks of subject analysis for the indexing of documents. Taking into account the contact of the learner indexers with the actual professional context, the proposals of Fourie Portfolio (2002) and Hjørland (2002) principle of the information science social context were applied in the discipline “Indexing” at UNESP Librarianship course in Marília, SP, Brazil. The results taken from this research on teaching strategies in documentary reading show that the methodological and theoretical knowledge, in socio-cognitive perspective, provide a view of a professional context in which the learner indexer is conscious of his strategies of documentary reading and can develop his previous professional knowledge in order to accomplish the indexing tasks compatible to the user informational demand.

In the organizational context culture and communication are fundamental to the processes of appropriation, sharing, generation and use of knowledge. However, in organizations, it is evident that there is little awareness about the influence of information culture and informational communication in the scope of knowledge management. In this perspective and considering the theoretical context, we analyze the influence of culture and communication in the construction of knowledge in an organizational context. This study presents a qualitative research covering national literature focusing theoretical literature published about this thematic. Analyzing this literature we have verified that without an appropriate information culture and an appropriate information communication favoring the organizational processes, hardly the managers would reach the purpose of stimulating knowledge creation within the organization's environment. In conclusion we consider that culture and communication are the foundations for the effectiveness of activities that occur within the context of knowledge management.

The research presents as its central theme the study of the bibliographic record conversion process. The object of study is framed by an understanding of analogic bibliographic record conversion to the Bibliograhpic MARC21 format, based on a syntactic and semantic analysis of records described according to descriptive metadata structure standards and content standards. The objective of this research the objective is to develop a theoretical-conceptual model of syntactic and semantic of bibliographic records, from Linguistic studies of Saussure and Hjelmslev of manifestations of human language, which subsidizes the development of a computacional interpreter, focused to the conversion of bibliographic records to MARC21 Bibliographic Format, which can be confirmed both the semantic value of the informational resource represented as the reliability of the representation. Given the aforementioned objectives, the methodological trajectory of the research is based on the qualitative approach, of an exploratory, descriptive and experimental nature, and with recourse to the literature. Contributions on the theoretical plane can be envisaged regarding the development of questions inherent to the syntactic and semantic aspects of bibliographic records, and by involving, at the same time, interdisciplinarity between Information Science, Computer Science and Linguistics. Contributions to the practical field are identified by the fact the study covers the development of the Scan for MARC, a computational interpreter that can be adopted by any institution that wishes to use the conversion procedure for bibliographic record databases to the MARC21 Bibliographic Format from description and visualization schemes of bibliographic records (AACR2r and ISBD), an aspect of the research which is considered innovative.

This article presents part of a larger study on the use of reference sources to perform bibliographical search by graduate students in Education. Data relating to the use of the scientific journals by these students are presented and discussed. Sixty Education graduate students, 28 Master degree and 32 Doctoral, answered an electronic questionnaire. The students indicated the types of articles usually read and the importance attributed to each one. For each of treated themes in the electronic questionnaire, data are initially presented and analyzed in the set of the 60 participants of the study and then compared between master and doctoral students. Were used the Chi-squared (?2) test, the Fisher exact test and the Spearman’s correlation coefficient. Research reports were more frequently pointed out but less valued in comparison to articles referring to critical review and theoretical essay. Methodological articles, appearing in fourth position according to reading frequency and importance attributed, are more valued by doctoral than master students. The students read these articles using different procedures. The possible reasons for the students valorizing the articles of critical review and theoretical essays are discussed. The present study intends to offer a contribution to understand the use of scientific information by students, describing some graduate students’ habits related to information seeking in scientific journals, and reading of the articles published.

Information retrieval has been much discussed within Information Science lately. The search for quality information compatible with the users needs became the object of constant research.Using the Internet as a source of dissemination of knowledge has suggested new models of information storage, such as digital repositories, which have been used in academic research as the main form of autoarchiving and disseminating information, but with an information structure that suggests better descriptions of resources and hence better retrieval.Thus the objective is to improve the process of information retrieval, presenting a proposal for a structural model in the context of the semantic web, addressing the use of web 2.0 and web 3.0 in digital repositories, enabling semantic retrieval of information through building a data layer called Iterative Representation.The present study is characterized as descriptive and analytical, based on document analysis, divided into two parts: the first, characterized by direct observation of non-participatory tools that implement digital repositories, as well as digital repositories already instantiated, and the second with scanning feature, which suggests an innovative model for repositories, with the use of structures of knowledge representation and user participation in building a vocabulary domain. The model suggested and proposed ─ Iterative Representation ─ will allow to tailor the digital repositories using Folksonomy and also controlled vocabulary of the field in order to generate a data layer iterative, which allows feedback information, and semantic retrieval of information, through the structural model designed for repositories. The suggested model resulted in the formulation of the thesis that through Iterative Representation it is possible to establish a process of semantic retrieval of information in digital repositories.

Digital repositories are currently being used by education and research institutions in Brazil as an alternative for propagating scientific and academic results, mainly to reach institutional memory and visibility. However, the way these results are presented may influence their use, affecting user-system interaction through the interface components. Thus, it is possible to state that an unique digital information environment can offer different ways of visual presentation, customizing informational and visual components for specific users communities. In this context, tools are being developed as a resource to make access and use of information easier, and to increase the usability of digital informational environments. One of these tools, Manakin, is presented in this paper, as well as its integration with the DSpace platform, in order to enable multiple visual presentations, stressing the importance of the differentiation and direction of interfaces by a single repository to the various knowledge fields. So, results and examples of repositories with multiple visual presentations are introduced, to facilitate the use of the presented tool, as well as to reinforce the importance of a differentiated visual identity by areas of knowledge in a single repository, by means of literary and exploratory analysis.
