BackgroundFunctional changes after spinal cord injury are related to changes in cortical plasticity. These changes can be measured with electroencephalography and has potential to be used as a clinical biomarker.MethodIn this longitudinal study participants underwent a total of 30 sessions of robotic-assisted gait training over a course of 6 weeks. The duration of each session was 30 min. Resting state EEG was recorded before and after 30-session rehabilitation therapy. To measure gait, we used the Walking Index for Spinal Cord Injury (...) Scale, 10-Meter- Walking Test, Timed-Up-and-Go, and 6-Min-Walking Test. Balance was measured using Berg Balance Scale.ResultsFifteen participants with incomplete SCI who had AIS C or D injuries based on American Spinal Cord Injury Association Impairment Scale classification were included in this study. Mean age was 35.7 years and the mean time since injury was 17.08 months. All participants showed clinical improvement with the rehabilitation program. EEG data revealed that high beta EEG activity in the central area had a negative correlation with gait and balance measured at baseline, in a way that greater high beta EEG power was related to worse clinical function at baseline. Moreover, improvement in gait and balance had negative correlations with the change in alpha/theta ratio in the parietal area.ConclusionIn SCI, functional impairment and subsequent improvement following rehabilitation therapy with RAGT correlated with the change in cortical activity measured by EEG. Our results suggest that EEG alpha/theta ratio may be a potential surrogate marker of functional improvement during rehabilitation. Future studies are necessary to improve and validate these findings as a neurophysiological biomarker for SCI rehabilitation. (shrink)

Multialgebras have been much studied in mathematics and in computer science. In 2016 Carnielli and Coniglio introduced a class of multialgebras called swap structures, as a semantic framework for dealing with several Logics of Formal Inconsistency that cannot be semantically characterized by a single finite matrix. In particular, these LFIs are not algebraizable by the standard tools of abstract algebraic logic. In this paper, the first steps towards a theory of non-deterministic algebraization of logics by swap structures are given. Specifically, (...) a formal study of swap structures for LFIs is developed, by adapting concepts of universal algebra to multialgebras in a suitable way. A decomposition theorem similar to Birkhoff’s representation theorem is obtained for each class of swap structures. Moreover, when applied to the 3-valued algebraizable logics J3 and Ciore, their classes of algebraic models are retrieved, and the swap structures semantics become twist structures semantics. This fact, together with the existence of a functor from the category of Boolean algebras to the category of swap structures for each LFI, suggests that swap structures can be seen as non-deterministic twist structures. This opens new avenues for dealing with non-algebraizable logics by the more general methodology of multialgebraic semantics. (shrink)

This volume is a critical investigation into the contemporary phenomenon of the dissensus of the globe and the planet, and the new terrains of consciousness that need to be negotiated towards a possibility for transformation. It examines the possibilities of alternate, sustainable modes of being and existing in a world which requires a unified, ethical, biopolitical worldview. The book explores themes like philosophical posthumanism and planetary concerns; disruption of cultural and intellectual inequality; bodily movement through nomadic subjectivity; dystopic spatialities of (...) game(re)play; globalization, and speculative imaginaries of the body; and theory of multiplicity. It also discusses impact of COVID on human beings, role of the neoliberal media, the question of rights of robots and cyborgs in sci-fi movies, and representation of refugees in literature. This book will be of interest to scholars and researchers of English literature, political philosophy, cultural studies, literary cultures, post-colonial studies, critical theory, and social anthropology.

This book presents a critical analysis of sense-making practices through an exploration of acoustic, creative, and artistic spaces. It studies how local cultures of sight, hearing, smell, taste, and touch are impacted by global discourses and media, such as television, popular music, digital media, and literature. The authors look at sense-making practices and spatial discourses through an interconnected discussion on thought and experience that seeks to present a multidimensional cartography of the global, the local, and the glocal, to closely analyze (...) the phenomenon of globalization. The volume is an investigation of the possibilities of alternate, sustainable modes of being and existing in a world which requires a unified, ethical, biopolitical worldview that challenges the disparity of its fragments while speculating on their synesthetic conditionality. A unique contribution, the book will be of interest to scholars and researchers of English literature, media studies, cultural studies, literary cultures, post-colonial studies, globalization studies, philosophy, critical theory, sociology, and social anthropology.

Despite being fairly powerful, finite non-deterministic matrices are unable to characterize some logics of formal inconsistency, such as those found between mbCcl and Cila. In order to overcome this limitation, we propose here restricted non-deterministic matrices (in short, RNmatrices), which are non-deterministic algebras together with a subset of the set of valuations. This allows us to characterize not only mbCcl and Cila (which is equivalent, up to language, to da Costa's logic C_1) but the whole hierarchy of da Costa's calculi (...) C_n. This produces a novel decision procedure for these logics. Moreover, we show that the RNmatrix semantics proposed here induces naturally a labelled tableau system for each C_n, which constitutes another decision procedure for these logics. This new semantics allows us to conceive da Costa's hierarchy of C-systems as a family of (non deterministically) (n+2)-valued logics, where n is the number of "inconsistently true" truth-values and 2 is the number of "classical" or "consistent" truth-values, for every C_n.

The logics of formal inconsistency (LFIs, for short) are paraconsistent logics (that is, logics containing contradictory but non-trivial theories) having a consistency connective which allows to recover the ex falso quodlibet principle in a controlled way. The aim of this paper is considering a novel semantical approach to first-order LFIs based on Tarskian structures defined over swap structures, a special class of multialgebras. The proposed semantical framework generalizes previous aproaches to quantified LFIs presented in the literature. The case of QmbC, (...) the simpler quantified LFI expanding classical logic, will be analyzed in detail. An axiomatic extension of QmbC called QLFI1o is also studied, which is equivalent to the quantified version of da Costa and D'Ottaviano 3-valued logic J3. The semantical structures for this logic turn out to be Tarkian structures based on twist structures. The expansion of QmbC and QLFI1o with a standard equality predicate is also considered. (shrink)

O presente trabalho procura se debruçar sobre a dimensão ontológica do homem animal-político-social em Aristóteles.

Refletindo, construindo e interligando o ser físico e “espiritual”. Portanto, o objeto principal será o que diz respeito ao homem como um animal político-social, no sentido ontológico do ser sensível em Aristóteles. Para tanto, a proposta (...) abarcará a Teoria das Quatro Causas de Aristóteles. Isso para demonstrar certa ontologia de uma suposta essência da ou na substancia no e do ser humano. Ou seja, quem é o “homem-ser-ente” coberto por sua estrutura física e sensível no sentido ontológico no corporal? São os seres humanos animais essencialmente políticos? E se forem são seres políticos do e ou no “espiritual”, “almático” e metafísico ou no físico-corporal? (shrink)

In 1986, Mikenberg et al. introduced the semantic notion of quasi-truth defined by means of partial structures. In such structures, the predicates are seen as triples of pairwise disjoint sets: the set of tuples which satisfies, does not satisfy and can satisfy or not the predicate, respectively. The syntactical counterpart of the logic of partial truth is a rather complicated first-order modal logic. In the present article, the notion of predicates as triples is recursively extended, in a natural way, to (...) any complex formula of the first-order object language. From this, a new definition of quasi-truth is obtained. The proof-theoretic counterpart of the new semantics is a first-order paraconsistent logic whose propositional base is a 3-valued logic belonging to hierarchy of paraconsistent logics known as Logics of Formal Inconsistency, which was proposed by Carnielli and Marcos in 2002.

In 1988, J. Ivlev proposed some (non-normal) modal systems which are semantically characterized by four-valued non-deterministic matrices in the sense of A. Avron and I. Lev. Swap structures are multialgebras (a.k.a. hyperalgebras) of a special kind, which were introduced in 2016 by W. Carnielli and M. Coniglio in order to give a non-deterministic semantical account for several paraconsistent logics known as logics of formal inconsistency, which are not algebraizable by means of the standard techniques. Each swap structure induces naturally a (...) non-deterministic matrix. The aim of this paper is to obtain a swap structures semantics for some Ivlev-like modal systems proposed in 2015 by M. Coniglio, L. Fariñas del Cerro and N. Peron. Completeness results will be stated by means of the notion of Lindenbaum–Tarski swap structures, which constitute a natural generalization to multialgebras of the concept of Lindenbaum–Tarski algebras.

Suszko's Thesis maintains that many-valued logics do not exist at all. In order to support it, R. Suszko offered a method for providing any structural abstract logic with a complete set of bivaluations. G. Malinowski challenged Suszko's Thesis by constructing a new class of logics (called q-logics by him) for which Suszko's method fails. He argued that the key for logical two-valuedness was the "bivalent" partition of the Lindenbaum bundle associated with all structural abstract logics, while his q-logics were generated (...) by "trivalent" matrices. This paper will show that contrary to these intuitions, logical two-valuedness has more to do with the geometrical properties of the deduction relation of a logical structure than with the algebraic properties embedded on it.

The article went deeper into Richard Rorty’s texts that address the self as “a set of beliefs and desires.” In an imbrication of philosophy with psychoanalysis, Rorty’s hermeneutics accompanies the critique of psychoanalysis regarding the self-centralization from Metaphysical tradition, one of the strategies of self-redescription. The other strategy is aesthetic redescription. This redescription is based on understanding the psychic world as an encounter of “beliefs and desires” as “quasi-people.” The thread of our argument is the articulation of psychoanalysis with the (...) concept of “hegemony.” This reflexive line occurs due to the agonist and conflicting context of internal alterity from the “interpersonal” relationship between conscious and unconscious, rediscovering the self.

Trying to overcome Dugundji’s result on uncharacterisability of modal logics by finite logical matrices, Kearns and Ivlev proposed, independently, a characterisation of some modal systems by means of four-valued multivalued truth-functions , as an alternative to Kripke semantics. This constitutes an antecedent of the non-deterministic matrices introduced by Avron and Lev . In this paper we propose a reconstruction of Kearns’s and Ivlev’s results in a uniform way, obtaining an extension to another modal systems. The first part of the paper (...) is devoted to four-valued Nmatrices, including Kearns’s and Ivlev’s. Besides proving with full details Kearns’s results for T, S4 and S5, we also obtain a characterisation of the system B by four-valued Nmatrices with level valuations. Concerning Ivlev’s results, two new modal systems are introduced and char.. (shrink)

Trata-se de um artigo de viés ensaístico que tenta apontar a impressão de que a instituição escolar habita uma densa crise existencial. A suposição que norteia essa reflexão visa à crise na educação escolar como uma aparência que costuma continuar velada na maior parte dos discursos críticos acerca da escolarização atual: o afastamento do sentido humano ontológico-social e do significado da experiência que relacionam professor-estudante. A investigação nesta atividade será realizada a partir de conceito recentemente desenvolvido, o absurdar-se, em uma (...) tentativa de aplicação desse conceito nas nossas experiências em escolas, nas quais atuamos como psicólogo da educação.

Education represents the practical criterion for the acculturation of political ideology on each side of the Arab-Israeli struggle through its role in the preparation and mobilization that precedes every stage. It has affected lifestyles on both sides. The subject of this study lies in the extent and clarity of each of the conflicting parties regarding the role of education and the impact on the vision to serve the interests of each. Therefore, political ideology at both sides of the struggle specifies (...) a vision for the role of education to build capable individuals and draws a picture of greatness in the minds of the youth according to the pattern, deemed sufficient and appropriate to realize excellence and superiority over the opponent. Inasmuch as that ideology is clear, education can effectuate the best condition to those on both sides who adhere to such a vision. (shrink)

We analyze the variety of A. Monteiro’s tetravalent modal algebras under the perspective of two logic systems naturally associated to it. Taking profit of the contrapositive implication introduced by A. Figallo and P. Landini, sound and complete Hilbert-style calculi for these logics are presented.

The aim of the paper is to analyze the expressive power of the square operator of Łukasiewicz logic: ∗x=x⊙x⁠, where ⊙ is the strong Łukasiewicz conjunction. In particular, we aim at understanding and characterizing those cases in which the square operator is enough to construct a finite MV-chain from a finite totally ordered set endowed with an involutive negation. The first of our main results shows that, indeed, the whole structure of MV-chain can be reconstructed from the involution and the (...) Łukasiewicz square operator if and only if the obtained structure has only trivial subalgebras and, equivalently, if and only if the cardinality of the starting chain is of the form n+1 where n belongs to a class of prime numbers that we fully characterize. Secondly, we axiomatize the algebraizable matrix logic whose semantics is given by the variety generated by a finite totally ordered set endowed with an involutive negation and Łukasiewicz square operator. Finally, we propose an alternative way to account for Łukasiewicz square operator on involutive Gödel chains. In this setting, we show that such an operator can be captured by a rather intuitive set of equations. (shrink)

A ideia de uma crise do rádio consolidou-se no imaginário coletivo nas últimas décadas, a despeito de não haver ancoragem na realidade. Se muitas rádios tradicionais AM e FM saem do ar, vendidas a igrejas eletrônicas ou novos grupos empresariais, multiplica-se a oferta de conteúdos no contexto de um rádio expandido, que transborda para novas plataformas e é consumido nos mais diversos dispositivos. O rádio vai bem, obrigado, embora algumas emissoras de rádio em ondas hertzianas estejam mal das pernas, lamentando-se (...) da concorrência com serviços on-line e da erosão dos habituais índices de audiência, antes medidos em centenas de milhares de ouvintes por minuto.

This study analyzes the possible occurrence of plagiarism and self-plagiarism in a sample of articles published in the Scientific Periodicals Electronic Library, an open database that indexes business journals in Brazil. The author compared one sample obtained in 2013 and another selected from 2018. In both samples, we verified the guidelines that each of the journals provided to authors regarding plagiarism and the adoption of software to detect textual similarities. In the analysis conducted in 2013, it was found that only (...) one journal mentioned the word “plagiarism” in its policies, although the majority of the directives required guarantees that no type of violation of authors’ rights was contained in the manuscript. In the analysis conducted in 2013, it was determined that there were literal reproductions in 31 published articles, and no relevant similarities with other publications were encountered in 16 articles. In the 2018 analysis, 69 of the publications included observations and guidelines related to plagiarism and self-plagiarism. In the analysis conducted in 2018, it was found that similarities occurred in 52 articles, and no relevant evidence of plagiarism or self-plagiarism was found in 66 manuscripts. Although a reduction in the index of the occurrence of plagiarism was observed, as was an increase in the instructions on the prevention of plagiarism by authors, practices directed at guiding authors by means of directives concerning the importance of preventing plagiarism in manuscripts submitted for publication can be recommended.

Este ensayo se propone presentar una lectura de las críticas de Aristóteles a Parménides en la Física. El autor sugiere que algunas importantes cuestiones que Aristóteles tiene en cuenta cuando determina los principios básicos de la ciencia de la naturaleza surgen de esas críticas. Boeri argumenta que, a pesar del fuerte desacuerdo declarado por Aristóteles en Física I 2-3 respecto de las posiciones eleáticas en general y la posición de Parménides en particular, Aristóteles aprovecha su discusión con Parménides de un (...) modo constructivo a favor de su propia teoría del cambio y, en general, de las condiciones indispensables para la constitución de la ciencia de la naturaleza. Según el autor, uno de los puntos centrales del desacuerdo de Aristóteles con Parménides es al mismo tiempo una de las más fértiles cuestiones desde el punto de vista del uso de Aristóteles de tal desacuerdo para establecer los fundamentos de su física.

A case situation arising in a normal interaction among people is the baseline for discussing properties of the theory of viewpoints. In particular we consider how to ensure agreement on the meaning of certain utterances by agents who have different perspectives on the situation, while maintaning other knowledge as private. We argue that communication should be modeled as adding facts to the common knowledge of agents. We introduce the principle of ''referent sharing'' in communications and argue that common knowledge resulting (...) from communication should only use constants whose referent is manifest to the parties involved.

Michel Foucault is one of the most preeminent theorists of power, yet the relationship between his militant activities and his analysis of power remains unclear. The book explores this relationship to explain the development of Foucault's thinking about power. Using newly translated and unpublished materials, it examines what led Foucault to take on the question of power in the early 1970s and subsequently refine his thinking, working through different models (war and government) and modalities (sovereign, disciplinary, biopolitical, pastoral and governmental). (...) Looking at Foucault's political trajectory, from his involvement with the prisoner support movement and Solidarity to his controversial engagement with the Iranian revolution, the book shows the militant underpinning of his interest in the question of power and its various shifts and mutations. This thorough account, which includes the first translation of a report edited by Foucault on prison conditions, will provide students in contemporary political theory with a better understanding of Foucault's thinking about power and of the interplay between political activities and theoretical productions.
