Hipersegmentação de palavras: análise de aspectos prosódicos e discursivos

This paper deals with hypersegmentation of words that are characterized by the unconventional employment of a graphical boundary (using a white space or hyphen) within the limits of the word, as in "em bora" (“although”, using a white space), and "chama-da" (“called”, using the hyphen). In a study conducted on these data, we identified motivations arising not only from their literate nature but also from the morphosyntactic and prosodic information. We showed that there are linguistic features recurrent in these registers of word boundaries, based on the analysis of texts produced by the students who attended the last four years of elementary school in a public school in São Paulo. In this paper, we advance on this study by selecting data whose characteristics do not match those which were recurrent. We will argue that the unconventional presence of boundary within the written word limits may be interpreted as representing prosodic configurations (of intonation and rhythm nature) which contribute to the construction of the relation of meanings in the text.

Eficiência das companhias aéreas brasileiras: uma análise envoltória de dados

Studies about efficiency have gained dimension, in Brazil, since the early 90’s. Same decade that the Civil Aviation System suffers important changes in terms of regulations. Such transformations have echoed effects currently, with some significant trend for international standards. This paper focuses on one of the agents from the Brazilian Civil Aviation System, the airlines companies, which aimed on analyze and evaluate both passengers and cargo air transport, by using data envelopment analysis (DEA), during the period of 2005 to 2010. The yearbooks of ANAC, corresponding at the period from 2005 to 2010, were used as data base in this present study. The technique was applied to 14 companies, which through Stepwise process of variables validation was possible to compose a compact, but complete model, that could translate the reality of companies. This model was composed by one output, Total Income, and by four inputs, Total Costs, Total Domestic Passenger, Total Cargo and Total International Passengers. However, this approach has some flaws. Therefore in order to remedy it, it was required to apply the method Frontier Inverted, one of the alternatives proposed in the literature, which ensured an improvement in the context of efficiencies due to biggest discrimination of airlines. As a result of the DEA-BCC process, oriented by output, TAM 2005 was considered the most efficient company, however GOL and Webjet companies concentrated in 2007 their worst levels

Otimização de portfólio utilizando como métricas de retorno medidas de posição central

This paper consists in applying the Modern Theory of Portfolio (MPT) using central position measurements for modeling the return on investment fund of a renowned financial institution and compare with the Medium- CVaR model. The measurement of risks and returns becomes increasingly important for investors to minimize their losses to maximize thus their possibilities of earnings, taking into account sudden change scenarios. We present concepts of investment funds used as data and research on central position measurements to determine which measure was more suitable. To assemble the Efficient Frontier of assets considering the method proposed measure of central position-CVaR position is used MatLab. Then, after getting the Frontier, it was possible to compare it with the Medium-CVaR model, already proven effective. Finally, we analyze the viability of the proposed model in portfolio management

Fronteiras nas Américas: tamanho e composição dos domicílios rurais no oeste do Brasil e EUA na primeira metade do século XIX

The study of the size and composition of the rural household in tradicional societies in transition to modern ones is very useful as a tool in order to understand forms and organizations of the domestic groups and their possibilities of survival, social mobility e developing strategies of material accumulation. The aim of this article is to compare the size and composition of the rural households in the frontier regions of the Americas: the northwest and southwest of U.S.A with the southwest of São Paulo province in Brazil. The findings are surprising in comparative perspective, as the mean size of the American households were very high in relation to the brazilian ones. The sources used in this research are the manuscript census of the U.S.A and Brazil.

Globalização, estado-nação e organização da sociedade civil

The questions that guide this article deal with the nation-State configuration and civil society organization, as well as the contours of the relation between both in the globalization context. As a qualitative change of internationalization, globalization brings to the social sciences field the discussion about its social impacts and the problematization about extinction of State. Thus, the article is guided by the debate between determined authors that deal with the analysis about new strategies of the State action, in order to understand where national States go, seeking to adapt themselves to the new context of Capital globalization.

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.
