Ensino e aprendizagem da leitura e da escrita na educação de jovens e adultos: diálogos com a educação infantil

This article aims to present a discussion of the methodological aspects of teaching and learning to read and write in adult education, in an attempt to seek a dialogue with the Early Childhood Education by pointing convergent elements between these two instances. And, therefore, it proposes a reflection on the construction of human nature and ownership of reading and writing as a humanizing process from the perspective of historical-cultural theory advocated by Vygotsky and his collaborators. In this context it is presented a pedagogical situation in a public school for kindergarten in the state of Sao Paulo, followed by analysis from the perspective of Bakhtin in order to make some approximations in the teaching and learning of the mother tongue with adults and children.

As relações entre Brasil e Venezuela durante os governos de Lula e Chávez - 2003 a 2010

This work examines the political-economic relations between Brazil and Venezuela from 2003 to 2010, during the mandates of Luiz Inácio Lula da Silva and Hugo Chavez Frías. After a historical overview of Venezuela, by showing the first approximations, it sets out the cooperation projects and makes a categorization and study of the International Acts signed during the studied period. The graphs and tables allowed a quantitative and qualitative analysis. The growth of the international trade is also considered and studied. The results show prospects that may contribute to cooperation and international trade between the two countries

Variational and perturbative schemes for a spiked harmonic oscillator

A variational analysis of the spiked harmonic oscillator Hamiltonian operator - d2/dx2 + x2 + l(l + 1)/x2 + λ|x| -α, where α is a real positive parameter, is reported in this work. The formalism makes use of the functional space spanned by the solutions of the Schrödinger equation for the linear harmonic oscillator Hamiltonian supplemented by a Dirichlet boundary condition, and a standard procedure for diagonalizing symmetric matrices. The eigenvalues obtained by increasing the dimension of the basis set provide accurate approximations for the ground state energy of the model system, valid for positive and relatively large values of the coupling parameter λ. Additionally, a large coupling perturbative expansion is carried out and the contributions up to fourth-order to the ground state energy are explicitly evaluated. Numerical results are compared for the special case α = 5/2. © 1989 American Institute of Physics.

Optimized delta expansion for relativistic nuclear models

The optimized delta-expansion is a nonperturbative approach for field theoretic models which combines the techniques of perturbation theory and the variational principle. This technique is discussed in the lambda phi(4) model and then implemented in the Walecka model for the equation of state of nuclear matter. The results obtained with the delta expansion are compared with those obtained with the traditional mean field, relativistic Hartree and Hartree-Fock approximations.

The Economic Impacts of Tourism in Ouro Preto, MG, Brazil

The tourism spending like other activities has direct and secondary effects on the economy, and presents complex interaction with other activities deserving a special treatment for measuring its contribution to the global result of production and consumption. In this paper, it is used the Money Generation Model to measure the global economic impact of tourism sales in Ouro Preto, this method is not so limited by the data and it is able to produce good approximations to reality. It was not possible to adopt the WTO methodology due to data limitation. The results revealed the real importance of tourism for Ouro Preto, representing up to 10.4% of GDP in 2002, up to 21.8% of tax revenues in 2004, and approximately 11% of the region’s population in 2002 was related to tourism sales. Some actions can be outlined from these results in order to illustrate the current economic reality of the tourism in Ouro Preto. It is also possible to improve the tourist planning accomplished by the local City Hall in a coherent way with the economic results generated by the tourism.
