Direitos de propriedade da terra rural no Brasil: uma proposta institucionalista para ampliar a governança fundiária

O artigo discute, sob uma perspectiva institucionalista, a dimensão do problema fundiário brasileiro expresso pela fragilidade dos direitos de propriedade da terra rural. Além dos condicionantes históricos referidos no texto, o artigo chama a atenção para o papel das instituições de registro e cadastro de imóveis que, por estarem separadas e não integradas, favorecem as práticas de fraude, apossamento e potencializam os conflitos fundiários. O artigo conclui com uma proposta de mudança institucional, baseada no aumento da governança da terra, no recente contexto favorável ao aperfeiçoamento da estrutura de direitos de propriedade da terra.

Arquitetura da informação no ambiente digital: avaliando as relações com o direito da propriedade intelectual

Investigates the relationship between Information Architecture in digital environments with Intellectual Property Rights. The work is justified by the need to better understand the emerging dynamics of Digital Information and Communication Law Technologies and Intellectual Property Rights. Three areas of knowledge are directly related to the study: Information Science, Law and Computer Science. The methodology used in the investigative process is aligned with the qualitative approach. With respect to the technical procedures the research is classified as bibliographic or secondary sources. The results showed that the current Brazilian legislation does not provide the adequate mechanisms necessary to protect the intellectual property rights associated to an Information Architecture project to its holders.

The WIPO development agenda and the contribution of the international library community

Purpose - The purpose of this paper is to analyze the international strengthening of copyright law in developing countries and the active involvement of the international library community in the movement against it.Design/methodology/approach - The paper describes the overprotection of intellectual property rights through international and bilateral treaties, the reaction against such through the proposal of a WIPO development agenda, and the contribution of the international library organizations to the debates and discussions in the WIPO arena.Findings - The initiative for a development agenda for WIPO has proven much more successful than many had imagined, even its promoters. The most relevant proposals made by the international library community were included in the final list of approved recommendations.Originality/value - The paper raises awareness of the relationship between copyright and access to knowledge and, in consequence, the need for library organizations to exert influence in such legislation.

Direitos de propriedade e usos econômicos da terra:um estudo de caso de assentamentos de reforma agrária no sul do Pará

This article discusses the Brazilian land problem related to property rights of rural land. After emphasizing the importance of land policies in order to define and distribute rural land properties rights, we show how in Brazil the institutions of rural land registering and cadastering as separated processes debilitates the property rights, making them vulnerable to the effective occupying actions. In order to illustrate it, in this article we analyze Data based in a Case Study of conflict and property rights distributions in an important farming and mining region of southern Para state, in Brazil.

Enhanced electrical property of nanostructured Sb-doped SnO2 thin film processed by soft chemical method

The effect of the Sb addition on the microstructural and electrical conductivity of the SnO2 thin film was studied in this work. Experimental results show that the Sb addition allowed to control the grain size and electrical conductivity of the SnO2 thin film, resulting in a nanostructured material. The nanostructured Sb-doped SnO2 thin films present high electrical conductivity, even in the presence of high porosity, supporting the hypothesis that nanostructured material must possess strong electrical conductivity. This work involves important aspects that can be applied to the development of high performance transparent conducting thin film. (C) 2003 Elsevier B.V. All rights reserved.

Photoluminescent property of mechanically milled BaWO4 powder

Crystalline BaWO4 (BWO) powder obtained by the polymeric precursor method was structurally disordered by means of high-energy mechanical milling. For the first time a strong and broad photoluminescence (PL) has been measured at room temperature for mechanically milled BWO powder and interpreted by ground-state quantum mechanical calculations in the density functional theory framework. Two periodic models have been studied; one representing the crystalline form and the other one representing the disordered BWO powder. These models allowed the calculation of electronic properties, which are consistent with the experimental results, showing that structural disorder in the lattice is an important condition to generate an intense and broad PL band.

Shape controlled synthesis of CaMoO4 thin films and their photoluminescence property

CaMoO4 (CMO) disordered and ordered thin films were prepared by the complex polymerization method (CPM). The films were annealed at different temperatures and time in a conventional resistive furnace (RF) and in a microwave (MW) oven. The microstructure and surface morphology of the structure were monitored by atomic force microscopy (AFM) and high-resolution scanning electron microscopy (HRSEM). Order and disorder were characterized by X-ray diffraction (XRD) and optical reflectance. A strong photoluminescence (PL) emission was observed in the disordered thin films and was attributed to complex cluster vacancies. The experimental results were compared with density functional and Hartree-Fock calculations. (C) 2008 Elsevier B.V. All rights reserved.
