Conservative translations

In this paper we introduce the concept of conservative translation between logics. We present some necessary and sufficient conditions for a translation to be conservative and study some general properties of logical systems, these properties being characterized by the existence of conservative translations between the systems. We prove that the class constituted by logics and conservative translations between them determines a co-complete subcategory of the bi-complex category constituted by logics and translations.

Considerações históricas sobre a difusão do pensamento Kleiniano no Brasil

This article describes the different moments that characterized the diffusion of Kleinian thought in psychoanalytic societies in Brazil. The article results from qualitative historical research based on interviews with thirteen psychoanalysts who participated in this process of diffusion. The first influences appeared in 1950, v pioneers trained either in Britain or in Argentina. The areas in which the Kleinians were pioneers -psychoanalysis of children and of psychotics - were the first aspects dealt with by this group in Brazil. Between 1950 and 1970 very dogmatic approaches were taken toward Kleinian ideas. As of 1980, with the publication of new, translations of Melanie Klein work and with the introduction of contemporary Kleinian thought, a more balanced use of this theoretical-technical model could been seen.

Culturally-sensitive complaints of depressions and anxieties in women

Background: Current classifications of Mental Disorders are centered on Westernized concepts and constructs. Cross-cultural sensitivity emphasizes culturally-appropriate translations of symptoms and questions, assuming that concepts and constructs are applicable.Methods: Groups and individual psychiatrists from various cultures from Asia, Latin America, North Africa and Eastern Europe prepared descriptions of main symptoms and complaints of treatment-seeking women in their cultures, which are interpreted by clinicians as a manifestation of a clinically-relevant dysphoric disorder. They also transliterated the expressions of DSM IV criteria of main dysphoric disorders in their cultures.Results: In many non-western cultures the symptoms and constructs that are interpreted and treated as dysphoric disorders are mostly somatic and are different from the Western-centered DSM or ICD systems. In many cases the DSM and ICD criteria of depression and anxieties are not even acknowledged by patients.Limitations: the descriptive approach reported here is a preliminary step which involved local but Westernized clinicians-investigators following a biomedical thinking. It should be followed by a more systematic-comprehensive surveys in each culture.Conclusions: Westernized concepts and constructs of mental order and disorders are not necessarily universally applicable. Culturallysensitive phenomena, treatments and treatment responses may be diversified. Attempts at their cross-cultural harmonization should take into consideration complex interactional multi-dimensional processes. (c) 2006 Elsevier B.V. All rights reserved.

Biological shape analysis by digital curvature

This paper reports the novel application of digital curvature as a feature for morphological characterization and classification of landmark shapes. By inheriting several unique features of the continuous curvature, the digital curvature provides invariance to translations, rotations, local shape deformations, and is easily made tolerant to scaling. In addition, the bending energy, a global shape feature, can be directly estimated from the curvature values. The application of these features to analyse patterns of cranial morphological geographic differentiation in the rodent species Thrichomys apereoides has led to encouraging results, indicating a close correspondence between the geographical and morphological distributions.

Kinematics of a spacetime with an infinite cosmological constant

A solution of the sourceless Einstein's equation with an infinite value for the cosmological constant L is discussed by using Inonu-Wigner contractions of the de Sitter groups and spaces. When Lambda --> infinity, spacetime becomes a four-dimensional cone, dual to Minkowski space by a spacetime inversion. This inversion relates the four-cone vertex to the infinity of Minkowski space, and the four-cone infinity to the Minkowski light-cone. The non-relativistic limit c --> infinity. is further considered, the kinematical group in this case being a modified Galilei group in which the space and time translations are replaced by the non-relativistic limits of the corresponding proper conformal transformations. This group presents the same abstract Lie algebra as the Galilei group and can be named the conformal Galilei group. The results may be of interest to the early Universe Cosmology.

Cosmological term and fundamental physics

A nonvanishing cosmological term in Einstein's equations implies a nonvanishing spacetime curvature even in the absence of any kind of matter. It would, in consequence, affect many of the underlying kinematic tenets of physical theory. The usual commutative spacetime translations of the Poincare group would be replaced by the mixed conformal translations of the de Sitter group, leading to obvious alterations in elementary concepts such as time, energy and momentum. Although negligible at small scales, such modifications may come to have important consequences both in the large and for the inflationary picture of the early Universe. A qualitative discussion is presented, which suggests deep changes in Hamiltonian, Quantum and Statistical Mechanics. In the primeval universe as described by the standard cosmological model, in particular, the equations of state of the matter sources could be quite different from those usually introduced.

Gravitation and the local symmetry group of space-time

According to general relativity, the interaction of a matter field with gravitation requires the simultaneous introduction of a tetrad field, which is a field related to translations, and a spin connection, which is a field assuming values in the Lie algebra of the Lorentz group. These two fields, however, are not independent. By analyzing the constraint between them, it is concluded that the relevant local symmetry group behind general relativity is provided by the Lorentz group. Furthermore, it is shown that the minimal coupling prescription obtained from the Lorentz covariant derivative coincides exactly with the usual coupling prescription of general relativity. Instead of the tetrad, therefore, the spin connection is to be considered as the fundamental field representing gravitation.

Metric-affine approach to teleparallel gravity

The teleparallel gravity theory, treated physically as a gauge theory of translations, naturally represents a particular case of the most general gauge-theoretic model based on the general affine group of spacetime. on the other hand, geometrically, the Weitzenbock spacetime of distant parallelism is a particular case of the general metric-affine spacetime manifold. These physical and geometrical facts offer a new approach to teleparallelism. We present a systematic treatment of teleparallel gravity within the framework of the metric-affine theory. The symmetries, conservation laws and the field equations are consistently derived, and the physical consequences are discussed in detail. We demonstrate that the so-called teleparallel GR-equivalent model has a number of attractive features which distinguishes it among the general teleparallel theories, although it has a consistency problem when dealing with spinning matter sources.

Sobre as traduções da obra de Wilhelm Reich para o português

O aumento dos textos traduzidos e da investigação acadêmica no campo reichiano realça a necessidade de se estar atento à qualidade das traduções dos textos de Reich para o português. Utilizando a palavra Trieb como exemplo, o objetivo deste artigo foi identificar quais os termos utilizados nas traduções dessa palavra para o português. Os resultados demonstraram, a exemplo do que acontece nas traduções da obra freudiana, que os termos mais comuns são: pulsão, instinto e impulso. Tal variação de termos reforça a necessidade de se cotejar diferentes traduções de um mesmo texto, de se confrontar os textos traduzidos com os textos originais e de se ater ao devido uso de termos específicos, contribuindo para que se leia, da melhor forma possível, as ideias originais de Reich em português.

As traduções de Bates: dois naturalistas no Rio Amazonas

Neste trabalho analisam-se duas traduções do relato da viagem do naturalista Henry Walter Bates pela Amazônia, uma publicada em 1944 na Coleção Brasiliana feita pelo naturalista Candido de Mello-Leitão, outra editada em 1979 na Coleção Reconquista do Brasil, assinada por Regina Regis Junqueira. O objetivo do artigo é problematizar a demarcação de limites nítidos entre uma ética da diferença e uma ética da igualdade, pois, em ambos os textos, tanto ocorre um movimento no sentido de preservar a alteridade do texto e do autor, quanto no de domesticar o texto. A análise busca também evidenciar que cada tradução, realizada a partir de diferentes projetos editoriais e tradutórios, acaba por suscitar diferentes imagens do naturalista e dos lugares por ele visitados.
