This paper aims to understand the nature of personal archives and their main features based on the collector entity IEB-USP (Instituto de Estudos Brasileiros da Universidade de São Paulo). Based on this entity and on archival theory, we discuss here, differences and similarities between the organic and private archives realizing the intrinsic value established on personal archival and how its institutionalization is denominated, once it directly pervades the attribution of value that is assigned and settled, relating to the work and life of a political or artistic personality, and also related to the collective memory and legacy left for this historically, aesthetic and socially important figures. We highlight, here, the approximation of Archival Science and Information Science and Library through the principles and organization methodologies applied to personal archives.

Thinking about research with children, giving time and voice to them is a discussion that is still fresh. Thus, in order to establish some reflections on the theoretical and methodological issues in research with children, we hope with this article to give visibility to the theoretical assumptions of authors who are concerned to place the child and childhood in the center of the research process. Thus, contributing to this discussion, this text is divided into three stages: initially bring some contributions of sociology of childhood and the various fields of knowledge to think about research with children. Secondly, we propose to discuss some methods and procedures that may favor the development of research with children. When we trace the historical development related to research with children and recover the concept of childhood and child while being active and producer of culture, we headed for the third time this work presents some results and conclusions, which can direct our gaze on pursuit of research instruments that capture what children think, feel and build in the world that they live and live together.

This article portrays pathways and studies, arising from research already completed on relationships that constitute the process of appropriation-objectification of the world of human culture by the child at the School for Children, under the gaze of Historical-Cultural Approach. The studies had been configured in accord with a theoretical look that understands the relations as propeller of the humanization process and the child as capable to learn since very small. Initially, there is deepening of theoretical issues concerning the regularities of human development between three and six years old, based on the propositions of the Historical-Cultural Approach. Subsequently, it presents results of the routes methodological that integrated observation sessions of educational practice in schools in early childhood education, involving the relationship between children, adults and objects, as well as sessions of designs and semi-structured interviews with the children. These results show the resulting analysis of the pedagogical implications of the propositions of the HistoricalCultural Approach about the humanization process, mediation and activity.

The purpose of this paper is to essentially provide a theoretical framework to industrial policies, especially showing the reasons for preference of a theoretical framework that is not based on equilibrium, and not based on maximization. We sought to define these policies, highlighting their positive results – at least potentially – in terms of some parameters (production, efficiency, productivity, income, welfare etc.). In this sense, we defined industrial policy, also analyzing the reasons for the usual lack of concern with a more rigorous theoretical framework for industrial policies. Following that, we briefly discussed whether or not a certain theory can lay the foundation for these policies, also examining if such theories are important (or not) in empirical terms. In the fourth section, we investigated the possible use of industrial policies, emphasizing market failures, public goods, non-competitive markets, externalities and technological development. Finally, we discussed about evaluation approaches of industrial and technological policies, focusing with more detail on the challenges related to the evaluation of economic effects of industrial and technological policies, and the methodologies of evaluation of these policies.

This papers deals with theoretical and methodological problems concerning the definition of criteria for the selection of sources for the study of language. Our work discussed the use and the importance of genre in the process of corpora construction as variation search – synchronic and diachronic.

The aim of this study was to review the current scientific literature to discuss the biomechanical behavior and characteristics inherent to both cast post and core and the prefabricated posts used in the practice of restoring endodontically treated teeth. To identify studies of this review, it was performed a detailed and advanced search strategy to the databases PubMed and Medline. It was used as descriptors: endodontically treated teeth, post, core, fiber post and metal post. Inclusion criteria were: clinical trials, randomized controlled trials, in vitro studies, literature reviews and systematic reviews with or without meta-analysis of the last 10 years that addressed the theme. Exclusion criteria were: articles without abstracts, animal studies, articles whose language was not English and articles from journals that do not belong to the Dentistry field. Of a total of 35 articles, after an analysis according to inclusion and exclusion criteria, 23 articles were selected. Most of the current scientific literature indicates that the prefabricated fiber reinforced and ceramic posts should be appointed for endodontically treated teeth that have a minimum height of 2mm ferrule. As for the cast metal cores, along with pre-fabricated metal represent a good prosthetic option, when weakened teeth have to be restored for any reason. Despite the large number of studies, there is still a lack of longterm prospective studies that evaluate the effectiveness of these posts in the treatment of endodontically treated teeth.
