Reinterpretando o Concílio Vaticano II: Impactos da Hermenêutica da Continuidade na música litúrgica católica do presente

In this paper, we asked whether a new interpretation given by Cardinal Joseph Ratzinger - Benedict XVI - to Vatican Council II, the Hermeneutics of Continuity can have an impact or have impacted yet the musical practice of the Roman Catholic liturgy. According to the Hermeneutics of Continuity, the council shall not constitute a break with previous liturgical practices, but a continuation of an organic movement. The analyses of data obtained from the literature and documentary procedures presented here were based on social autopoietic systems theory by Niklas Luhmann and on the concept of invented tradition by Eric Hobsbawm. We conclude that the Hermeneutics of Continuity has proved to be more a reform of the reform than the reconciliation between two musical and liturgical practices.

A propósito dos parâmetros curriculares nacionais e sua relação com o ethos cultural hodierno

The text focuses on the relation between the Law of Directives and Bases of National Education, as well as its deployment in the National Curriculum, and contemporary culture in three aspects: the predominantly naive about the relation between technological development / education, the translation rhetoric about family’s institution as a partner of educational practices, and finally, the use of systems theory applied to the context of politicaleducational diagnosis. Results from a larger research project in progress titled "Cultural Industry and formative processes: Subsidies to reflect the new educational demmands”.

Development of neurofuzzy architecture for solving the N-Queens problem

Neural networks are dynamic systems consisting of highly interconnected and parallel nonlinear processing elements that are shown to be extremely effective in computation. This paper presents an architecture of recurrent neural networks for solving the N-Queens problem. More specifically, a modified Hopfield network is developed and its internal parameters are explicitly computed using the valid-subspace technique. These parameters guarantee the convergence of the network to the equilibrium points, which represent a solution of the considered problem. The network is shown to be completely stable and globally convergent to the solutions of the N-Queens problem. A fuzzy logic controller is also incorporated in the network to minimize convergence time. Simulation results are presented to validate the proposed approach.

Intencionalidade e linguagem (II): algumas considerações sobre Tomaselo, Searle e Dennett

Propomos, neste trabalho, que o conceito de intencionalidade é uma ferramenta relevante para a interpretação de repertórios simbólicos humanos. Analisamos como os conceitos de intencionalidade e de linguagem verbal são articulados na Teoria da Aquisição da Linguagem Baseada no Uso de Tomasello, na Teoria dos Atos Ilocucionários de Searle e na Teoria dos Sistemas Intencionais de Dennett, buscando identificar seu papel na determinação da cognição humana. Essas teorias propõem uma interdependência entre esses conceitos, os quais difeririam entre si quanto ao modo como se dá essa articulação. Elas também destacam a importância dos repertórios simbólicos, especialmente a linguagem verbal, para a cognição humana. Como a intencionalidade é um aspecto da cognição humana, uma conexão entre linguagem verbal e intencionalidade para o funcionamento cognitivo humano é uma questão a ser investigada na psicologia científica.

Nonlocal growth processes and conformal invariance

Up to now the raise-and-peel model was the single known example of a one-dimensional stochastic process where one can observe conformal invariance. The model has one parameter. Depending on its value one has a gapped phase, a critical point where one has conformal invariance, and a gapless phase with changing values of the dynamical critical exponent z. In this model, adsorption is local but desorption is not. The raise-and-strip model presented here, in which desorption is also nonlocal, has the same phase diagram. The critical exponents are different as are some physical properties of the model. Our study suggests the possible existence of a whole class of stochastic models in which one can observe conformal invariance.

Entanglement of excited states in critical spin chains

Renyi and von Neumann entropies quantifying the amount of entanglement in ground states of critical spin chains are known to satisfy a universal law which is given by the conformal field theory (CFT) describing their scaling regime. This law can be generalized to excitations described by primary fields in CFT, as was done by Alcaraz et al in 2011 (see reference [1], of which this work is a completion). An alternative derivation is presented, together with numerical verifications of our results in different models belonging to the c = 1, 1/2 universality classes. Oscillations of the Renyi entropy in excited states are also discussed.

Both the dorsal hippocampus and the dorsolateral striatum are needed for rat navigation in the Morris water maze

The multiple memory systems theory proposes that the hippocampus and the dorsolateral striatum are the core structures of the spatial/relational and stimulus-response (S-R) memory systems, respectively. This theory is supported by double dissociation studies showing that the spatial and cue (S-R) versions of the Morris water maze are impaired by lesions in the dorsal hippocarnpus and dorsal striatum, respectively. In the present study we further investigated whether adult male Wistar rats bearing double and bilateral electrolytic lesions in the dorsal hippocampus and dorsolateral striatum were as impaired as rats bearing single lesions in just one of these structures in learning both versions of the water maze. Such a prediction, based on the multiple memory systems theory, was not confirmed. Compared to the controls, the animals with double lesions exhibited no improvement at all in the spatial version and learned the cued version very slowly. These results suggest that, instead of independent systems competing for holding control over navigational behaviour, the hippocampus and dorsal striatum both play critical roles in navigation based on spatial or cue-based strategies.

Um balanço de parte da teoria dos sistemas intencionais de Dennett

Dennett (1981/1987b) caracteriza sua abordagem do funcionamento dos termos intencionais (aqueles para as assim chamadas atitudes proposicionais) como um "behaviorismo lógico holista", ou versão holista de delineamentos conceituais traçados por Ryle (1949). Este artigo avalia algumas de suas possíveis contribuições e desvantagens para tais delineamentos, e algumas consequências para sua proposta de utilização destes termos em psicologia. Argumenta-se que a abordagem não se mostra mais plausível do que a de seu predecessor, caso a dimensão mentalista que lhe acrescenta seja equivocada, e que de fato este é o caso. Disso resulta que suas contribuições e proposta correlata devem ser entendidas com independência daquilo que tal dimensão implica. Uma alternativa não-mentalista, baseada no modelo selecionista de Skinner, para uma eventual adoção dos termos intencionais em psicologia, é brevemente discutida.
