The future of awake bruxism assessment will incorporate physiological data, possibly electromyography of the temporal muscles. But up to now, temporal muscle contraction patterns in awake bruxism have not been characterized to demonstrate clinical utility. The present study aimed to perform surface EMG evaluations of people assessed for awake bruxism to identify possible different subtypes. A 2-year active search for people with awake bruxism in three regions of the country resulted in a total of 303 participants. Their inclusion was confirmed (...) through non-instrumental approaches for awake bruxism: self-reported questionnaire and clinical exam, performed by three experienced and calibrated dentists. Also, 77 age- and sex-matched healthy controls were recruited. Temporalis surface EMG was performed with a portable device. EMG signals were sent to a computer via Bluetooth 4.0 at a sampling rate of 1,000 Hz. Digital signal processing was performed using the commercial neuroUP software, transformed in RMS and then normalized for peak detection, in a 10 min session. Cluster analysis revealed three distinct subtypes of awake bruxism: phasic, tonic, and intermediate. Individuals with a predominance of EMG peaks/min were classified as the “phasic” subtype. Those with the highest EMG rest power were classified as the “tonic” subtype. There was also an “intermediate” subtype, when both variables remained low. Characterization of awake bruxism physiology is important for future establishment of instrumental assessment protocols and treatment strategies. (shrink)

We introduce a methodology whereby an arbitrary logic system L can be enriched with temporal features to create a new system T(L). The new system is constructed by combining L with a pure propositional temporal logic T (such as linear temporal logic with Since and Until) in a special way. We refer to this method as adding a temporal dimension to L or just temporalising L. We show that the logic system T(L) preserves several properties of the original temporal logic (...) like soundness, completeness, decidability, conservativeness and separation over linear flows of time. We then focus on the temporalisation of first-order logic, and a comparison is make with other first-order approaches to the handling of time. (shrink)

This paper investigates modular combinations of temporal logic systems. Four combination methods are described and studied with respect to the transfer of logical properties from the component one-dimensional temporal logics to the resulting combined two-dimensional temporal logic. Three basic logical properties are analyzed, namely soundness, completeness, and decidability. Each combination method comprises three submethods that combine the languages, the inference systems, and the semantics of two one-dimensional temporal logic systems, generating families of two-dimensional temporal languages with varying expressivity and varying (...) degrees of transfer of logical properties. The temporalization method and the independent combination method are shown to transfer all three basic logical properties. The method of full join of logic systems generates a considerably more expressive language but fails to transfer completeness and decidability in several cases. So a weaker method of restricted join is proposed and shown to transfer all three basic logical properties. (shrink)

In this paper we study families of resource aware logics that explore resource restriction on rules; in particular, we study the use of controlled cut-rule and introduce three families of parameterised logics that arise from different ways of controlling the use of cut. We start with a formulation of classical logic in which cut is non-eliminable and then impose restrictions on the use of cut. Three Cut-and-Pay families of logics are presented, and it is shown that each family provides an (...) approximation process for full propositional classical logic when the control over the use of cut is progressively weakened. A sound and complete semantics is given for each component of each of the three families of approximated logics. One of these families is shown to possess the uniform substitution property, a new result for approximated reasoning. A tableau based decision procedure is presented for each element of the approximation families and the complexity of each decision procedure is studied. We show that there are families in which every component logic can be decided polynomially. (shrink)

This work studies the structure of proofs containing non-analytic cuts in the cut-based system, a sequent inference system in which the cut rule is not eliminable and the only branching rule is the cut. Such sequent system is invertible, leading to the KE-tableau decision method. We study the structure of such proofs, proving the existence of a normal form for them in the form of a comb-tree proof. We then concentrate on the problem of efficiently computing non-analytic cuts. For that, (...) we study the generalisation of techniques present in many modern theorem provers, namely the techniques of conflict-driven formula learning. (shrink)

In this paper we explore a generalization of traditional abduction which can simultaneously perform two different tasks: given an unprovable sequent Γ ⊢ G, find a sentence H such that Γ, H ⊢ G is provable ; given a provable sequent Γ ⊢ G, find a sentence H such that Γ ⊢ H and the proof of Γ, H ⊢ G is simpler than the proof of Γ ⊢ G . We argue that the two tasks should not be distinguished, (...) and present a general procedure for finding suitable hypotheses or lemmas. When the original sequent is provable, the abduced formula can be seen as a cut formula with respect to Gentzen's sequent calculus, so the abduction method is cut-based. Our method is based on the tableau-like system KE and we argue for its advantages over existing abduction methods based on traditional Smullyan-style Tableaux. (shrink)

Background: The new human coronavirus that leads to COVID-19 has spread rapidly around the world and has a high degree of lethality. In more severe cases, patients remain hospitalized for several days under treatment of the health team. Thus, it is important to develop and use technologies with the aim to strengthen conventional therapy by encouraging movement, physical activity, and improving cardiorespiratory fitness for patients. In this sense, therapies for exposure to virtual reality are promising and have been shown to (...) be an adequate and equivalent alternative to conventional exercise programs.Aim: This is a study protocol with the aim of comparing the conventional physical therapy intervention with the use of a non-immersive VR software during COVID-19 hospitalization.Methods: Fifty patients hospitalized with confirmed diagnosis of COVID-19 will be divided in two groups under physiotherapy treatment using conventional or VR intervention: Group A: participants with COVID-19 will start the first day of the protocol with VR tasks in the morning and then in the second period, in the afternoon, will perform the conventional exercises and Group B: participants with COVID-19 will start the first day with conventional exercises in the morning and in the second period, in the afternoon, will perform activity with VR. All participants will be evaluated with different motor and physiologic scales before and after the treatment to measure improvements.Conclusion: Considering the importance of benefits from physical activity during hospitalization, VR software shows promise as a potential mechanism for improving physical activity. The results of this study may provide new insights into hospital rehabilitation.Trial Registration:ClinicalTrials.gov, identifier: NCT04537858. Registered on 01 September 2020. (shrink)

De 1964 a 1985 o Brasil viveu sob um regime de governo ditatorial que de acordo com a historiografia mais recente foi sustentado, em grande parte, pela própria sociedade civil (MELO, 2012; COMISSÃO, 2014). Mais recentemente, a partir dos anos 1980, cresce o movimento de criação de espaços de memória corporativos com o objetivo de tornar pública a trajetória histórica das empresas (COSTA; SARAIVA, 2011). Dentre estes espaços, adquire relevância os Centros de Memória e documentação como lugares de armazenamento e (...) lembrança de memória organizacional, que ajudam a construir simbolicamente a imagem organizacional e a fornecer um senso de coerência e trajetória linear (RIBEIRO; BARBOSA, 2007). Neste contexto, e com base na documentação disponibilizada pela Comissão Nacional da Verdade, a presente pesquisa tem por objetivo identificar como o Museu Histórico da Fundação Bradesco retrata (ou deixa de retratar) o relacionamento da empresa Bradesco com o governo brasileiro no período da ditadura civil-militar. FIRMS, BRAZILIAN CIVIL-MILITARE DICTATORSHIP, AND MEMORY AND CORPORATIVE DOCUMENTATION CENTERS: AN EXPLORATORY STUDY From 1964 to 1985, Brazil lived under a dictatorial system of government that according to the latest historiography was sustained largely by civil society (MELO, 2012; COMISSÃO, 2014). More recently, since the 1980s, it is possible to be noticed the growing movement of creation of corporate memory spaces in order to make public the historical trajectory of the companies (COSTA and SARAIVA, 2011). Among these spaces, acquires relevance the Corporate Documentation and Memory Centers, which help to symbolically build the organizational image and to provide a sense of consistency and linear trajectory (RIBEIRO and BARBOSA, 2007). In this context, and based on documentation provided by the National Commission of Truth, this research aims to identify how the History Museum of Bradesco Foundation portrays (or does not portray) the relationship between Bradesco company and the Brazilian government in the period of civil-military dictatorship.

IntroductionRegular exercise has long been shown to positively impact the immune system responsiveness and improve mental well-being. However, the putative links between biomarkers of mental health and immune efficiency in exercising subjects have been scarcely investigated. The aim of this study was to verify the effect of a 14-week combined chair-based exercise program on salivary steroid hormones and anti-microbial proteins, functional fitness, and MWB indexes in pre-frail older women.MethodsThe participant women were randomly divided into the exercising group and the non-exercising (...) control group. The pre/post assessment included: salivary anti-microbial proteins lysozyme; and immunoglobulin-A ; salivary steroid hormones of testosterone and cortisol ; functional fitness ; MWB questionnaires.ResultsSignificant differences with large Cohen’s effect sizes were found on increased salivary TT after exercise intervention. The results revealed a decrease in IgA levels after CEP. The increase in subjective happiness levels and decrease of stress perception and depressive state were found after intervention in the CEP group. Robust statistical differences in gait speed and balance tests were also found in the CEP group. In control, COR increased moderately while no changes were found for the other indicators. Correlation analyses showed inter-dependence between pre–post variations of MWB, biochemical indexes, and fitness function.ConclusionThe CEP program was able to improve functional-fitness performance, decrease feelings of stress, and increase happiness. The CEP also induced clinically relevant hormonal and immune responses, which suggests that chair exercises that combine muscular strength, balance, and gait speed training are promising interventions to improve physical and mental health of older pre-frail adults.

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.

In this paper we propose to enrich the four-valued modal logic associated to Monteiro's Tetravalent modal algebras (TMAs) with a deductive implication, that is, such that the Deduction Meta-theorem holds in the resulting logic. All this lead us to establish some new connections between TMAs, symmetric (or involutive) Boolean algebras, and modal algebras for extensions of S5, as well as their logical counterparts.

This paper generalises and complements the work on combining temporal logics started by Finger and Gabbay [11, 10]. We present proofs of transference of soundness, completeness and decidability for the temporalisation of logics T for any flow of time, eliminating the original restriction that required linear time for the transference of those properties through logic combination. We also generalise such results to the external application of a multi-modal system containing any number of connectives with arbitrary arity, that respect normality.This (...) generalisation over generic flows of time propagates to other combinations of logics that can be interpreted in terms of temporalisations. In this way, the independent combination of temporal logics is studied over generic flows of time. We show the transfer of soundness, completeness and decidability for independent combination of temporal logics. Finally, we also discuss the independent combination of any finite number of normal multi-modal logics. (shrink)

Tetravalent modal logic (TML) was introduced by Font and Rius in 2000. It is an expansion of the Belnap-Dunn four-valued logic FOUR, a logical system that is well-known for the many applications found in several fields. Besides, TML is the logic that preserves degrees of truth with respect to Monteiro’s tetravalent modal algebras. Among other things, Font and Rius showed that TML has a strongly adequate sequent system, but unfortunately this system does not enjoy the cut-elimination property. However, in (...) a previous work we presented a sequent system for TML with the cut-elimination property. Besides, in this same work, it was also presented a sound and complete natural deduction system for this logic. In the present article we continue with the study of TML under a proof-theoretic perspective. In the first place, we show that the natural deduction system that we introduced before admits a normalization theorem. In the second place, taking advantage of the contrapositive implication for the tetravalent modal algebras introduced by A. V. Figallo and P. Landini, we define a decidable tableau system adequate to check validity in the logic TML. Finally, we provide a sound and complete tableau system for TML in the original language. These two tableau systems constitute new (proof-theoretic) decision procedures for checking validity in the variety of tetravalent modal algebras. (shrink)

Agenda Relevance is the first volume in the authors' omnibus investigation of the logic of practical reasoning, under the collective title, A Practical Logic of Cognitive Systems. In this highly original approach, practical reasoning is identified as reasoning performed with comparatively few cognitive assets, including resources such as information, time and computational capacity. Unlike what is proposed in optimization models of human cognition, a practical reasoner lacks perfect information, boundless time and unconstrained access to computational complexity. The practical reasoner is (...) therefore obliged to be a cognitive economizer and to achieve his cognitive ends with considerable efficiency. Accordingly, the practical reasoner avails himself of various scarce-resource compensation strategies. He also possesses neurocognitive traits that abet him in his reasoning tasks. Prominent among these is the practical agent's striking (though not perfect) adeptness at evading irrelevant information and staying on task. On the approach taken here, irrelevancies are impediments to the attainment of cognitive ends. Thus, in its most basic sense, relevant information is cognitively helpful information. Information can then be said to be relevant for a practical reasoner to the extent that it advances or closes some cognitive agenda of his. The book explores this idea with a conceptual detail and nuance not seen the standard semantic, probabilistic and pragmatic approaches to relevance; but wherever possible, the authors seek to integrate alternative conceptions rather than reject them outright. A further attraction of the agenda-relevance approach is the extent to which its principal conceptual findings lend themselves to technically sophisticated re-expression in formal models that marshal the resources of time and action logics and label led deductive systems. Agenda Relevance is necessary reading for researchers in logic, belief dynamics, computer science, AI, psychology and neuroscience, linguistics, argumentation theory, and legal reasoning and forensic science, and will repay study by graduate students and senior undergraduates in these same fields. Key features: relevance action and agendas practical reasoning belief dynamics non-classical logics labelled deductive systems. (shrink)

Neste livro, discute-se a visão do filósofo sobre a teoria do conhecimento e da ciência, além de tópicos mais particulares, mas nem por isso menos cruciais, como sua crítica ao finalismo, sua relevância para a leitura de Freud e a tese humeana, retomada por Quine, da continuidade entre conhecimento comum e teórico.

Goal Directed Proof Theory presents a uniform and coherent methodology for automated deduction in non-classical logics, the relevance of which to computer science is now widely acknowledged. The methodology is based on goal-directed provability. It is a generalization of the logic programming style of deduction, and it is particularly favourable for proof search. The methodology is applied for the first time in a uniform way to a wide range of non-classical systems, covering intuitionistic, intermediate, modal and substructural logics. The book (...) can also be used as an introduction to these logical systems form a procedural perspective. Readership: Computer scientists, mathematicians and philosophers, and anyone interested in the automation of reasoning based on non-classical logics. The book is suitable for self study, its only prerequisite being some elementary knowledge of logic and proof theory. (shrink)

Inductive Logic is number ten in the 11-volume Handbook of the History of Logic. While there are many examples were a science split from philosophy and became autonomous (such as physics with Newton and biology with Darwin), and while there are, perhaps, topics that are of exclusively philosophical interest, inductive logic — as this handbook attests — is a research field where philosophers and scientists fruitfully and constructively interact. This handbook covers the rich history of scientific turning points in Inductive (...) Logic, including probability theory and decision theory. Written by leading researchers in the field, both this volume and the Handbook as a whole are definitive reference tools for senior undergraduates, graduate students and researchers in the history of logic, the history of philosophy, and any discipline, such as mathematics, computer science, cognitive psychology, and artificial intelligence, for whom the historical background of his or her work is a salient consideration.

In this paper I offer a characterization of the intellectual virtue of social inquisitiveness, paying attention to its difference from the individual virtue of inquisitiveness. I defend that there is a significant distinction between individual and social epistemic virtues: individual epistemic virtues are attributed to individuals and assessed by the quality of their cognitive powers, while social epistemic virtues are attributed to epistemic communities and are assessed by the quality of the epistemic relations within the communities. I begin presenting Lani (...) Watson's characterization of the (individual) practice of questioning and its related intellectual virtue, inquisitiveness. While she does not employ normative language, I show that her description can be constructed through four norms. Then, based on an account of epistemic communities, I defend that, while epistemic virtues attributable to individuals have norms regulating cognitive powers, epistemic virtues attributable to epistemic communities have norms regulating social epistemic interactions and shared epistemic responsibility. I then present a robust characterization of the epistemic virtue of social inquisitiveness through its social epistemic norms: DISTRIBUTION, ACCESSIBILITY, SOCIAL SINCERITY, SOCIAL CONTEXT, and FREQUENCY. I respond to two possible objections to my account and conclude by offering suggestions to broaden the scope of the epistemology of questioning. (shrink)

O manuscrito clandestino Jordanus Brunus redivivus ou Traité des erreurs populaires foi publicado em 1771, não trazendo indicação alguma de sua autoria. Entretanto, a despeito do anonimato da obra, ela tornou-se um dos textos mais famosos dentre a filosofia clandestina do século XVIII, aludindo a um filósofo que foi uma das maiores vítimas da superstição e do fanatismo de sua época: Giordano Bruno. O título do escrito é uma espécie de homenagem ao pensador italiano, mas não há no decorrer da (...) obra uma menção sequer que comprove que o autor anônimo tenha lido uma linha de suas obras, mesmo que seja considerado o elo filosófico de união entre o brunismo da primeira metade do século XVII e o da segunda metade do século XVIII. É em um encadeamento de ideias progressivo no Jordanus Brunus que nos permite encontrar o fio condutor das reflexões do autor: a sua formulação do ateísmo caracteriza-se por sua abordagem não dogmática, dissimulada, preparando o solo para o racionalismo ateu que estaria por vir. O presente artigo limitar-se-á à terceira e quarta partes do manuscrito, nas quais o autor anônimo vai tratar diretamente da questão da existência de deus e fazer diversas objeções às provas de sua existência.

Donald Davidson’s anomalous monism has been repeatedly criticized since its initial defense in the paper Mental Events, which was published in 1970. Despite the widespread rejection, there seems to be no agreement on why anomalous monism fails. This paper systematizes two strong objections to anomalous monism. First, Davidson’s argument for monism requires the problematic assumption that physics can provide strict causal laws for causal relations in general. Second, Davidson’s monism requires an ontology of events for which no satisfactory criterion of (...) identity has been provided. Despite these problems, the paper argues that the theses on the anomalism and irreducibility of the mental remain acceptable, despite the difficulty of reconstructing precisely the arguments Davidson uses to defend them.

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)

Belnap–Dunn’s relevance logic, \(\textsf{BD}\), was designed seeking a suitable logical device for dealing with multiple information sources which sometimes may provide inconsistent and/or incomplete pieces of information. \(\textsf{BD}\) is a four-valued logic which is both paraconsistent and paracomplete. On the other hand, De and Omori, while investigating what classical negation amounts to in a paracomplete and paraconsistent four-valued setting, proposed the expansion \(\textsf{BD2}\) of the four valued Belnap–Dunn logic by a classical negation. In this paper, we introduce a four-valued expansion (...) of BD called \({\textsf{BD}^\copyright }\), obtained by adding an unary connective \({\copyright }\,\ \) which is a consistency operator (in the sense of the Logics of Formal Inconsistency, _LFI_s). In addition, this operator is the unique one with the following features: it extends to \(\textsf{BD}\) the consistency operator of LFI1, a well-known three-valued _LFI_, still satisfying axiom _ciw_ (which states that any sentence is either consistent or contradictory), and allowing to define an undeterminedness operator (in the sense of Logic of Formal Undeterminedness, _LFU_s). Moreover, \({\textsf{BD}^\copyright }\) is maximal w.r.t. LFI1, and it is proved to be equivalent to BD2, up to signature. After presenting a natural Hilbert-style characterization of \({\textsf{BD}^\copyright }\) obtained by means of twist-structures semantics, we propose a first-order version of \({\textsf{BD}^\copyright }\) called \({\textsf{QBD}^\copyright }\), with semantics based on an appropriate notion of four-valued Tarskian-like structures called \(\textbf{4}\) -structures. We show that in \({\textsf{QBD}^\copyright }\), the existential and universal quantifiers are interdefinable in terms of the paracomplete and paraconsistent negation, and not by means of the classical negation. Finally, a Hilbert-style calculus for \({\textsf{QBD}^\copyright }\) is presented, proving the corresponding soundness and completeness theorems. (shrink)

The present work is completely grounded in the methodology of textual analysis as present in buddhist studies and has three essential pretentions. The first one is to discuss the relationship between the conceptual and non-conceptual dimensions of buddhist practice from the standpoint of the concept of the three wisdoms. The second one is to define a central standpoint able to judge the difference between buddhist practice proper and the therapeutic and scientific approaches to meditation. The third one tries to think (...) the complete autonomy of the conceptual dimension from an analysis of the relationship between the three wisdoms and the three worlds in the Satya-siddhi-Sãstra.

Uma das formas do poder feminino-africano se manifesta de forma acentuada no campo da espiritualidade, tanto no mundo visível, ou seja, dos vivos, quanto no mundo invisível, o dos mortos. Este artigo faz parte de uma pesquisa em andamento, sobre o poder exercido pelas mulheres africanas e que raras vezes são consideradas ou visibilizadas como formas de poder na contramão de uma vasta literatura em que as mulheres, na sua maioria, são consideradas submissas. O interesse recai sobre práticas de tornar-se (...) djambakus, Balobêru, nganga, Mutombe ou tchimbanda em duas realidades, a guineense e a angolana. A riqueza dos relatos das experiências de uma guineense, moradora de Ziguinchor, Senegal, com foco nas tradições ancestrais para transmitir e explicar o sagrado por intermédio da história oral, reforçam a análise da concepção do lugar destas mulheres no exercício do poder ocultado. O trabalho é de caráter teórico-qualitativo: revisão de literatura, entrevistas e história oral. O recurso da oralidade dialoga com a condição de escassez de documentos escritos sobre curandeiras, djambacus, Balobêru e nganga que se dedicam a curar. Foi entrevistada uma djambakus que transita entre Guiné-Bissau e Senegal. Os resultados apontam para a potência de mulheres na prática sagrada de cura pelo encontro de conhecimentos populares, saberes africanos tradicionais, ancestrais e do bem-estar de suas comunidades ou tabancas.

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.

Judging a person as morally responsible involves believing that certain responses (such as punishment, reward, or expressions of blame or praise) can be justifiably directed at the person. This paper develops an account of the evolution of moral responsibility judgment that adopts Michael Tomasello’s two-step theory of the evolution of morality and borrows also from Christopher Boehm’s work. The main hypothesis defended is that moral responsibility judgment originally evolved as an adaptation that enabled groups of cooperative individuals to hold free (...) riders responsible more safely by acting in a coordinated way.

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)

Nietzsche and Education: knowledge and culture in the Modern State Abstract: This text seeks to do some reflections on the relationship between Friedrich Nietzsche's philosophy and the educational field, understanding his inquiries about modern educational institutions and the values ​​linked to this type of man. United with the process of degeneration of human instinctual power and its animality, there was the establishment of a model of knowledge, based on the metaphysical ideal and on the unconditional belief of truth. The criticism directed at the Modern State and its model of culture, which intended to establish philosophers and scholars as guides, understands that it is necessary to rescue the uses and functions of these subjects in society, seeking to overcome the dilemma that constitutes them today, as employees and keepers of the state. Passing through different phases of his thought, we sought to be one more instrument to provide the scope of Philosophy of Education with a solid link with the German philosopher, through the study of the relationship between Nietzsche and Education.

The notion of negation is basic to any formal or informal logical system. When any such system is presented to us, it is presented either as a system without negation or as a system with some form of negation. In both cases, we are supposed to know intuitively whether there is no negation in the system or whether the form of negation presented in the system is indeed as claimed. To be more specific, suppose Robinson Crusoe writes a logical system (...) with Hilbert-type axioms and rules, which includes a unary connective ∗A\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$*A$$\end{document}. He puts the document in a bottle and lets it lose at sea. We find it and take a look. We ask: is the connective “∗\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$*$$\end{document}” a negation in the system? Yet the notion of what is negation in a formal system is not clear. When we see a unary connective ∗A\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$*A$$\end{document}, together with some other axioms for some additional connectives, how can we tell whether ∗A\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$*A$$\end{document} is indeed a form of negation of A? Are there some axioms which the connective “∗\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$*$$\end{document}” must satisfy in order to qualify ∗\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$*$$\end{document} as a negation?

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.

O presente trabalho procura se debruçar sobre a dimensão ontológica do homem animal-político-social em Aristóteles. Logo, desde já nos cabe ressaltar que a verificação do homem enquanto animal político-social abarcará um caráter metafísico para a efetivação no e do físico-material-natural, ou seja, o ser biopsicossocial. 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 the final pages of Chapter V of Afro-Brazilian Religions Roger Bastide sees, at a given moment in the socio-religious evolution of Brazil, a process of social disorganization which in its extent affects not only blacks but also poor white nationals and stranded immigrants.* As generator of a “ social marginalization,” this process could only be the passage through “a moment of transition” characterized by “the exaggerated speed of change in the country.” According to Bastide, an “organic period” follows: with (...) the “proletarization of the blacks, the assimilation of the immigrants, the general rise in the standard of living of the masses, other phenomena of cultural and social reintegration will appear.” On the religious level the “spiritism of umbanda“ is the expression of this new phase.
