In dynamical systems models feedforward is needed to guide planning and to process unknown and unpredictable events. Feedforward could help Theory of Event Coding (TEC) integrate control processes and could model human performance in action planning in a more flexible and powerful way.
Este artigo propõe-se a discutir a possibilidade de utilizar as tecnologias digitais online e as redes sociais como espaço de aprendizagem digital de uma maneira que favoreça a aprendizagem cooperativa entre os estudantes, alicerçado na Epistemologia Genética de Jean Piaget. Este estudo foi baseado em uma pesquisa-ação, nas aulas de Matemática, realizada com estudantes do ensino médio integrado em informática do IFRS – Campus Osório (RS), em 2011 e 2012-1. Os estudantes demonstraram apropriação deste espaço de aprendizagem digital, como o (...) Facebook, e apontaram que este potencializa a aprendizagem cooperativa no que tange à disciplina de Matemática, por ações colaborativas com a professora. (shrink)
This paper focuses on one of the original moments of the development of the “phenomenological” current of psychiatry, namely, the psychopathological research of Ludwig Binswanger. By means of the clinical and conceptual problem of schizophrenia as it was conceived and developed at the beginning of the twentieth century, I will try to outline and analyze Binswanger’s perspective from a both historical and epistemological point of view. Binswanger’s own way means of approaching and conceiving schizophrenia within the scientific, medical, and psychiatric (...) context of that time will lead us to grasp the epistemological stakes at the origins of his project of reforming psychiatry by means of phenomenology. I will finally attempt to upgrade and update Binswanger’s project in light of the current reappraisal of phenomenology within the ongoing debate on psychopathology engaged by studies in the field of science and philosophy of mind.

Things are not the same when, even remaining the same, they are placed on the right or on the left, above or below, in front or behind. In the concrete space of our daily experience, in the space of myths and religions, we are not confronted with a neutral, homogeneous, infinite and isotropic spatiality, indifferent to directions. On the contrary, the possibility of a meaningful movement in space, rooted in my own body and in its praxis (as Kant shows in (...) his pre-critical and critical essays devoted to the space regions and to orientation), is assigned to the three main axes (above/below, right/left, front/behind) and their correspondent differences. The same applies for the space of images and pictures. The present issue of “Aisthesis” aims at exploring how the articulations above/below, right/left, front/behind produce a difference – syntactic, semantic, pragmatic and symbolic – in the iconic domain, and at investigating what theoretical models can be employed in order to understand such difference.

Finite demi-p-lattices are described in terms of the poset of its join irreducible elements endowed with a suitable set of maps. Description of the free algebras of demi-p-lattices and almost-p-lattices with n free generators are given.
The 16th and 17th centuries marked a period of transition from the vitalistic ontology that had dominated Renaissance natural philosophy to the Early Modern mechanistic paradigm endorsed by, among others, the Cartesians and Newtonians. This paper focuses on how the tensions between vitalism and mechanism played themselves out in the context of 16th and 17th century chemistry and chemical philosophy. The paper argues that, within the fields of chemistry and chemical philosophy, the significant transition that culminated in the 18th century (...) Chemical Revolution was not a transition from vitalism to full-blown mechanism. Rather, chemical philosophy shifted from a vitalistic theory of matter and spirits to a naturalistic, physicalistic, and corpuscularian conception of chemical properties and reactions. Despite being naturalistic, physicalistic, and corpuscularian, however, this theory was not fully mechanistic. Special attention is paid to the contributions made by Paracelsus, Sebastien Basso, Jan Baptista van Helmont, and Robert Boyle to this ontological transition. (shrink)

Only propositional logics are at issue here. Such a logic is contra-classical in a superficial sense if it is not a sublogic of classical logic, and in a deeper sense, if there is no way of translating its connectives, the result of which translation gives a sublogic of classical logic. After some motivating examples, we investigate the incidence of contra-classicality (in the deeper sense) in various logical frameworks. In Sections 3 and 4 we will encounter, originally as an example of (...) what (in Section 2) we call a contra-classical modal logic, an unusual logic boasting a connective (" demi-negation" ) whose double application is equivalent to a single application of the negation connective. Pondering the example points the way to a general characterization of contra-classicality (Theorems 3.3 and 4.6). In an Appendix (Section 5), we look at one alternative to classical logic as the target for such translational assimilation, intuitionistic logic, calling logics which resist the assimilation, in this case, contra- intuitionistic. We will show that one such logic is classical logic itself, thereby strengthening a result of Wojcicki's to the effect that the consequence relation of classical logic cannot be faithfully embedded by any connective-by-connective translation into that of intuitionistic logic. (What the "faithfully" means here is that not only is the translation of anything provable in the 'source' logic.. (shrink)
The three demi-articles presented here would give a brief biographical account of Ludwig Boltzmann’s life plus some details about his Vienna laboratories first in the 1860’s in the Erdberg and second in Türkenstrasse from 1894. Josef Nabl’s account discusses J. J. Thomson’s Laboratory in Cambridge, which allows a provisional comparison between two different largely contemporary institutes. Nabl’s second letter also mentions Lord Kelvin’s late rejection of the kinetic gas theory of Maxwell and Boltzmann, rejection which on top of the negative (...) attitude of Mach, Zermelo, and Poincaré probably did not benefit Boltzmann’s state of mind and may have contributed to the extreme character of Boltzmann’s anti-philosophical counterattack starting in 1903.

In this paper we use Hobby's duality for semi-De Morgan algebras, to characterize those algebras having only principal congruences in the classes of semi-De Morgan algebras, demi-pseudocomplemented lattices and almost pseudocomplemented lattices. This work extends some of the results reached by Beazer in  and .
David Harvey : On peut difficilement imaginer vérification plus spectaculaire de ce que tu prédis depuis très longtemps dans tes théories que l’actuelle crise du système financier mondial. Y a-t-il des aspects de la crise qui t’ont surpris ?Giovanni Arrighi : Ma prédiction était très simple. Dans The Long Twentieth Century, je qualifiais de crise annonciatrice d’un régime d’accumulation le début de la financiarisation et je faisais remarquer qu’après un certain temps – en général environ un demi-siècle – la crise (...) terminale suivait. L’hypothèse fondamentale est que toutes ces expansions financières ne pouvaient pas tenir parce qu’elles amenaient à la spéculation plus de capital qu’il n’était possible d’en gérer – en d’autres termes, ces expansions financières avaient tendance à créer des bulles de différentes sortes. Je prévoyais que cette expansion financière mènerait à une crise terminale parce que, aujourd’hui comme dans le passé, les bulles ne peuvent pas tenir. (shrink)
While attempting to avoid closure, it can be argued that two of the analytical techniques employed by Lawson (1997) strongly imply closure. First, while ostensibly directed at liberating analysis from all forms of closure, the demi?reg is shown to effectively rely on implied closure. Second, when the use of control groups is compared to Mäki's method of isolation, it can be shown that Lawson implies substantially similar closure to that which is proposed by Mäki. Such implied forms of closure generally (...) indicate that the complete exclusion of closure remains somewhat problematic. Accordingly, it is suggested that Lawson's effective prohibition on closure might be moderated by adopting the judicious and careful use of closure, within the context of an open system. (shrink)
