In a context of global change, inland navigation transport has gained interest with economic and environmental benefits. The development of this means of conveyance requires the improvement of its management rules to deal with the increase of navigation and the potential impact of global change. To achieve this aim, it is first necessary to have a better knowledge about the dynamics of inland navigation networks and their interaction with the environment. Second, the potential effects of global change have to be (...) anticipated. This article focuses on the modeling of inland navigation reaches. An inland navigation network is a large-scale distributed system composed of several interconnected reaches. These reaches are characterized by non-linearities, time delays, and generally no significant slope. To deal with these particularities, a gray-box model is proposed. It consists in determining the delays according to the physical characteristics of the system. The parameters of the model are identified with measured data. The gray-box model is used to reproduce the dynamics of the Cuinchy–Fontinettes reach located in the north of France. (shrink)

Taking a detour to reach a goal is intelligent behavior based on making inferences. The main purpose of the present research is to show how such apparently complex behavior can emerge from basic mechanisms such as contextual categorisation and goal attribution when perceiving people. We presentacacia (Action by Contextually Automated Categorising Interactive Agents), a computer model implemented using StarLogo software, grounded in the principles of Artificial Life (Al), capable of simulating the behavior of a group of agents with a goal (...) (for instance, to find a treasure in a treasure hunt ) in an environment where obstacles mask the goal site. The results of the simulations show that agents reach the goal the fastest when they follow each other and take detours. We argue that these results indicate that intelligent adaptive behavior is based on the contextual categorisation of environmental constrainst (that is, obstacles and other agents). (shrink)

The rapid dynamics of COVID-19 calls for quick and effective tracking of virus transmission chains and early detection of outbreaks, especially in the “phase 2” of the pandemic, when lockdown and other restriction measures are progressively withdrawn, in order to avoid or minimize contagion resurgence. For this purpose, contact-tracing apps are being proposed for large scale adoption by many countries. A centralized approach, where data sensed by the app are all sent to a nation-wide server, raises concerns about citizens’ privacy (...) and needlessly strong digital surveillance, thus alerting us to the need to minimize personal data collection and avoiding location tracking. We advocate the conceptual advantage of a decentralized approach, where both contact and location data are collected exclusively in individual citizens’ “personal data stores”, to be shared separately and selectively, voluntarily, only when the citizen has tested positive for COVID-19, and with a privacy preserving level of granularity. This approach better protects the personal sphere of citizens and affords multiple benefits: it allows for detailed information gathering for infected people in a privacy-preserving fashion; and, in turn this enables both contact tracing, and, the early detection of outbreak hotspots on more finely-granulated geographic scale. The decentralized approach is also scalable to large populations, in that only the data of positive patients need be handled at a central level. Our recommendation is two-fold. First to extend existing decentralized architectures with a light touch, in order to manage the collection of location data locally on the device, and allow the user to share spatio-temporal aggregates—if and when they want and for specific aims—with health authorities, for instance. Second, we favour a longer-term pursuit of realizing a Personal Data Store vision, giving users the opportunity to contribute to collective good in the measure they want, enhancing self-awareness, and cultivating collective efforts for rebuilding society.

Twinned 2H martensite is observed in copper-based shape memory alloys together with basal and non-basal plane stacking faults. Knowledge of the twin-boundary structure and its interaction with the faults is important to understand the deformation mechanism by twin coalescence. High-resolution electron microscopy coupled with image simulations have been used for these studies. The interface of the type I twinning in 2H martensite shows an atomic configuration with mirror antisymmetry. An atomic plane is shared by the twinned variants in such a (...) way that the distance between the planes, parallel to the interface, is unchanged at the boundary and the mean atomic volume is conserved. The interaction of the boundary with a basal plane fault generates a shift in the interface. A mirror antisymmetrical boundary is maintained by introducing an imperfect interface dislocation.

This paper contains a joint study of two sentential logics that combine a many-valued character, namely tetravalence, with a modal character; one of them is normal and the other one quasinormal. The method is to study their algebraic counterparts and their abstract models with the tools of Abstract Algebraic Logic, and particularly with those of Brown and Suszko's theory of abstract logics as recently developed by Font and Jansana in their "A General Algebraic Semantics for Sentential Logics". The logics (...) studied here arise from the algebraic and lattice-theoretical properties we review of Tetravalent Modal Algebras, a class of algebras studied mainly by Loureiro, and also by Figallo, Landini and Ziliani, at the suggestion of the late Antonio Monteiro.

This is a contribution to the discussion on the role of truth degrees in manyvalued logics from the perspective of abstract algebraic logic. It starts with some thoughts on the so-called Suszko’s Thesis (that every logic is two-valued) and on the conception of semantics that underlies it, which includes the truth-preserving notion of consequence. The alternative usage of truth values in order to define logics that preserve degrees of truth is presented and discussed. Some recent works studying these in the (...) particular cases of Łukasiewicz’s many-valued logics and of logics associated with varieties of residuated lattices are also presented. Finally the extension of this paradigm to other, more general situations is discussed, highlighting the need for philosophical or applied motivations in the selection of the truth degrees, due both to the interpretation of the idea of truth degree and to some mathematical difficulties.

A filter of a sentential logic ? is Leibniz when it is the smallest one among all the ?-filters on the same algebra having the same Leibniz congruence. This paper studies these filters and the sentential logic ?+ defined by the class of all ?-matrices whose filter is Leibniz, which is called the strong version of ?, in the context of protoalgebraic logics with theorems. Topics studied include an enhanced Correspondence Theorem, characterizations of the weak algebraizability of ?+ and of (...) the explicit definability of Leibniz filters, and several theorems of transfer of metalogical properties from ? to ?+. For finitely equivalential logics stronger results are obtained. Besides the general theory, the paper examines the examples of modal logics, quantum logics and Łukasiewicz's finitely-valued logics. One finds that in some cases the existence of a weak and a strong version of a logic corresponds to well-known situations in the literature, such as the local and the global consequences for normal modal logics; while in others these constructions give an independent interest to the study of other lesser-known logics, such as the lattice-based many-valued logics.

ukasiewicz''s four-valued modal logic is surveyed and analyzed, together with ukasiewicz''s motivations to develop it. A faithful interpretation of it in classical (non-modal) two-valued logic is presented, and some consequences are drawn concerning its classification and its algebraic behaviour. Some counter-intuitive aspects of this logic are discussed in the light of the presented results, ukasiewicz''s own texts, and related literature.

In this paper we study the relations between the fragment L of classical logic having just conjunction and disjunction and the variety D of distributive lattices, within the context of Algebraic Logic. We prove that these relations cannot be fully expressed either with the tools of Blok and Pigozzi's theory of algebraizable logics or with the use of reduced matrices for L. However, these relations can be naturally formulated when we introduce a new notion of model of a sequent calculus. (...) When applied to a certain natural calculus for L, the resulting models are equivalent to a class of abstract logics (in the sense of Brown and Suszko) which we call distributive. Among other results, we prove that D is exactly the class of the algebraic reducts of the reduced models of L, that there is an embedding of the theories of L into the theories of the equational consequence (in the sense of Blok and Pigozzi) relative to D, and that for any algebra A of type (2,2) there is an isomorphism between the D-congruences of A and the models of L over A. In the second part of this paper (which will be published separately) we will also apply some results to give proofs with a logical flavour for several new or well-known lattice-theoretical properties.

In this paper two deductive systems associated with relevance logic are studied from an algebraic point of view. One is defined by the familiar, Hilbert-style, formalization of R; the other one is a weak version of it, called WR, which appears as the semantic entailment of the Meyer-Routley-Fine semantics, and which has already been suggested by Wójcicki for other reasons. This weaker consequence is first defined indirectly, using R, but we prove that the first one turns out to be an (...) axiomatic extension of WR. Moreover we provide WR with a natural Gentzen calculus. It is proved that both deductive systems have the same associated class of algebras but different classes of models on these algebras. The notion of model used here is an abstract logic, that is, a closure operator on an abstract algebra; the abstract logics obtained in the case of WR are also the models, in a natural sense, of the given Gentzen calculus.

Łukasiewicz’s infinite-valued logic is commonly defined as the set of formulas that take the value 1 under all evaluations in the Łukasiewicz algebra on the unit real interval. In the literature a deductive system axiomatized in a Hilbert style was associated to it, and was later shown to be semantically defined from Łukasiewicz algebra by using a “truth-preserving” scheme. This deductive system is algebraizable, non-selfextensional and does not satisfy the deduction theorem. In addition, there exists no Gentzen calculus fully adequate (...) for it. Another presentation of the same deductive system can be obtained from a substructural Gentzen calculus. In this paper we use the framework of abstract algebraic logic to study a different deductive system which uses the aforementioned algebra under a scheme of “preservation of degrees of truth”. We characterize the resulting deductive system in a natural way by using the lattice filters of Wajsberg algebras, and also by using a structural Gentzen calculus, which is shown to be fully adequate for it. This logic is an interesting example for the general theory: it is selfextensional, non-protoalgebraic, and satisfies a “graded” deduction theorem. Moreover, the Gentzen system is algebraizable. The first deductive system mentioned turns out to be the extension of the second by the rule of Modus Ponens. (shrink)

Industry 5.0 and Healthcare 5.0 converge towards a human centered society, having technological advancement as a lever. In Society 5.0, decentralized autonomous cities and a convergence of physical and cyberspace are the foundations of the new chapter of society’s development. The idea of creating digital replicas and legitimate representatives of human beings in cyberspace has become a pillar of digitalization. Society 5.0 introduces Human Digital Twins as a central element of Cyber Physical Systems that include human factors or are designed (...) to interact with humans in a personalized fashion. Overall, the HDT and neighboring concepts are applied to depict how humans can be represented in a cyberspace. However, there are clear challenges in determining which human characteristics should take precedence, how much autonomy should be granted to HDTs to optimize their functionality and how to conceptualize the digital environment in which HDTs interact with various entities, including other digital agents and stakeholders with agency and decisional power. To harness similarities and differences of current approaches, we propose a classification of HDTs based on meta-characteristics and ethical implications. We discuss ethical implication by focusing on emerging risks and paradigm shifts and anchor the previous discussion in the vision for Society 5.0, questioning whether societal development relying on disruptive technologies, instead of leading to more human-centered societies might be driving humanized societies away from humanity.

A definition and some inaccurate cross-references in the paper A Survey of Abstract Algebraic Logic, which might confuse some readers, are clarified and corrected; a short discussion of the main one is included. We also update a dozen of bibliographic references.

In this paper we consider the structure of the class FGModS of full generalized models of a deductive system S from a universal-algebraic point of view, and the structure of the set of all the full generalized models of S on a fixed algebra A from the lattice-theoretical point of view; this set is represented by the lattice FACSs A of all algebraic closed-set systems C on A such that (A, C) ε FGModS. We relate some properties of these structures (...) with tipically logical properties of the sentential logic S. The main algebraic properties we consider are the closure of FGModS under substructures and under reduced products, and the property that for any A the lattice FACSs A is a complete sublattice of the lattice of all algebraic closed-set systems over A. The logical properties are the existence of a fully adequate Gentzen system for S, the Local Deduction Theorem and the Deduction Theorem for S. Some of the results are established for arbitrary deductive systems, while some are found to hold only for deductive systems in more restricted classes like the protoalgebraic or the weakly algebraizable ones. The paper ends with a section on examples and counterexamples. (shrink)

The “representation problem” in abstract algebraic logic is that of finding necessary and sufficient conditions for a structure, on a well defined abstract framework, to have the following property: that for every structural closure operator on it, every structural embedding of the expanded lattice of its closed sets into that of the closed sets of another structural closure operator on another similar structure is induced by a structural transformer between the base structures. This question arose from Blok and Jónsson abstract (...) analysis of one of Blok and Pigozzis’s characterizations of algebraizable logics. The problem, which was later on reformulated independently by Gil-Férez and by Galatos and Tsinakis, was solved by Galatos and Tsinakis in the more abstract framework of the category of modules over a complete residuated lattice, and by Galatos and Gil-Férez in the even more abstract setting of modules over a quantaloid. We solve the representation problem in Blok and Jónsson’s original context of M-sets, where M is a monoid, and characterise the corresponding M-sets both in categorical terms and in terms of their inner structure, using the notions of a graded M-set and a generalized variable introduced by Gil-Férez.

In the article, I include examples from qualitative and quantitative studies in many nations. I (...) also offer suggestions for researchers and institutional review boards. (shrink)

This paper reviews the impact of Rasiowa's well-known book on the evolution of algebraic logic during the last thirty or forty years. It starts with some comments on the importance and influence of this book, highlighting some of the reasons for this influence, and some of its key points, mathematically speaking, concerning the general theory of algebraic logic, a theory nowadays called Abstract Algebraic Logic. Then, a consideration of the diverse ways in which these key points can be generalized allows (...) us to survey some issues in the development of the field in the last twenty to thirty years. The last part of the paper reviews some recent lines of research that in some way transcend Rasiowa's approach. I hope in this way to give the reader a general view of Rasiowa's key position in the evolution of Algebraic Logic during the twentieth century. (shrink)

SummaryIn this synthetic exposition, devoted to the relations which exist between psľchic functions and anatomic structures, Dr Pontes first insists on the difficulties of the subject and of its scientific analysis. Soma, Psyche, and social Milieu form a kind of continuum which is artificiallľ dissociated by our one‐sided approaches. Experimentation cannot be fullľ practised on man, nor can its results on animal be extended to man without serious risks of error. Similar limitations appear if, resorting to the pathological method, we (...) try to apply to the normal conclusions arrived at through the Study of the abnormal. Special reference is made here to psychosurgery, a topic quite familiar to Dr Fontes, who is Dr Egas Moniz’ countryman.The author then summarises our present knowledge concerning the structure, connections and functions of encephalic centers, especially; the thalamus, the hypothalamus and the frontal lobes.Finally, he subscribes, though not without serious reservations, to the hierarchical conception of the Nervous Sľstem as well as of the human mind, first suggested by Jouffroy, after him developed by Baillarger, Janet, Wallon in France, by Hughlings Jackson in Great Britain, and recentlľ revived in Europe by von Mona‐kow and Mourgue, Eľ, and Delaľ. This view enables one to consider nervous or psľchic illnesses as various dissolutions, resulting on the one hand from the suppression of higher centers or powers, on the other hand from the liberation of lower ones. It agrees rather well with the informations gathered by the anatomy and the physiology of the nervous sľstem, and with the conclusions suggested by psychosurgical opérations. To the thalamus and hypothalamus correspond the lower and older manifestations of mind: emotion and instinct, to the cortex the higher and more recent adaptive and intellectual processes. The hypothalamus plays a most important role in the nervous machinery as a regulator of vegetative and instinctive life, of wake and sleep, of consciousness, and of the basic biological rhythms. At the cortical level the frontal lobe appears as the structural basis for such psychical functions as Ego‐control, Will, Personality, and succèssfull action on the milieu. (shrink)

ABSTRACT In this paper we introduce a set of six logical values, arising in the application of three-valued logics to time intervals, find its algebraic structure, and use it to define a six-valued logic. We then prove, by using algebraic properties of the class of De Morgan algebras, that this semantically defined logic can be axiomatized as Belnap's ?useful? four-valued logic. Other directions of research suggested by the construction of this set of six logical values are described.

This paper is concerned with the particular problems raised by observations of phenomena outside the common course of nature for their validation as knowledge. It examines to what extent the content of the reports and, in particular, their lack of intrinsic plausibility affected the methods used in their authentication and the assessment of testimony at the Royal Society in the first half of the eighteenth century. I show that literary strategies were usually necessary but not sufficient for the validation of (...) these kinds of observations. Next, I discuss why visual representations were especially useful in establishing the singularity of the observations, but I point out that their high costs and other restrictions meant that they were not so widespread. In contrast I show that, for a long period of time, testimony was used in the majority of the reports as the true stamp of authenticity. I note, however, that the Royal Society accepted reports by authors of varied social status, level of education and occupation, and I discuss some of the factors responsible for the complexity of the handling of testimony at the Society. I argue against Shapin that in the case of reports of extraordinary phenomena, the competence of the reporter and witnesses was often more important than their social status. The increasing role of expertise in the assessment of observations at the Society become especially apparent by the middle of the eighteenth century.Author Keywords: Authentication; Competence; Monstrous births; Singular; Testimony; Royal Society of London.

A pair of deductive systems (S,S’) is Leibniz-linked when S’ is an extension of S and on every algebra there is a map sending each filter of S to a filter of S’ with the same Leibniz congruence. We study this generalization to arbitrary deductive systems of the notion of the strong version of a protoalgebraic deductive system, studied in earlier papers, and of some results recently found for particular non-protoalgebraic deductive systems. The necessary examples and counterexamples found in the (...) literature are described. (shrink)

In her well-known book, Rasiowa states without proof that in implicative algebras there is a one-to-one correspondence between kernels of epimorphisms and the so-called special implicative filters, and that in the logic whose algebraic counterpart is the class of implicative algebras the deductive filters coincide with the special implicative filters. We show that neither claim is true, and how to repair the situation by redefining some of the notions involved. We answer other questions concerning special implicative filters, taking the theory (...) of algebraizable logics of Blok and Pigozzi as a framework to approach the question in a systematic way.

Axel Honneth desenvolve o conceito de reconhecimento, encarado como uma necessidade fundamental do ser-humano, de forma a constituir-se no núcleo de uma teoria da justiça que procura especificar as condições intersubjetivas de autorrealização individual. Apresenta-se uma teoria da justiça assente na reconstrução das práticas e condições de reconhecimento já institucionalizadas, analisando as instituições sociais em um sentido amplo. Pretende-se aproximar a concepção normativa da justiça da análise sociológica das sociedades modernas, através da reconstrução normativa e ao colocar a ênfase na (...) liberdade social, baseada na dimensão intersubjetiva das instituições de reconhecimento. A liberdade social prevê o acesso às instituições de reconhecimento. Um dos objetivos é esboçar os problemas desse avanço interpretativo da teoria crítica do reconhecimento, pelo que iremos convocar a teoria da luta pelo reconhecimento de Honneth, incluir a sua reactualização mais recente do Direito de Hegel e explorar a sua proposta normativa para as condições de uma vida ética.

Our research considers The Ethics of Authenticity to be a synthesis of Charles Taylor's political theory, from which he carries out a critical evaluation of modern Western culture and analyses its main ailments in order to then highlight its principle of vitality: authenticity. Throughout Western history, authenticity was considered to be an individual search for the self, based on a detached rationality that didn't consider horizons of meaning or relationships with significant others. Through Taylor's theory, this perspective has changed: authenticity (...) is now described as a dialogical moral ideal, based on recognition. The continuous construction of our identity depends on relationships of recognition, as a proper way of safeguarding an ethically authentic existence. (shrink)

O objetivo do presente texto é mostrar, pela técnica argumentativa retórico-dissociativa, o caráter tópico de toda dissociação nocional e de todo discurso filosófico, de tal forma que, em vez de resolver uma incompatibilidade, como costumam pensar os retóricos, tais dissociações servem de suporte, incontestado, mas não incontestável, de um discurso que se revela, assim, sempre circunscrito e comprometido com escolhas. Desta forma, procuramos estabelecer as cinco regras da dissociação que visam facilitar a aplicação dessa técnica. A importância de tal objetivo (...) é criar algumas condições de resistência e contestação discursiva que despertem a crítica e a reflexão próprias de uma conversação infinita pela tomada de consciência do nosso próprio “senso de relatividade” e sua aplicação relacionada ao preconceito, ao discurso de ódio e aos direitos humanos.

El objetivo de este artículo es situar contextualmente y explicar algunas de las bases de la acción y el discurso de la corriente de la Tradición Iberoamericana de los Derechos Humanos (TIDH). La llegada de los europeos a América fue abordada por la Escuela ibérica de la Paz desde las premisas de una tradición que esbozó una Modernidad católica diferente a la Modernidad hegemónica. La influencia de esas visiones permitió que el proyecto de la Monarquía hispánica en general, y para (...) el Nuevo Mundo en particular, contase con una importante dimensión ético-religiosa. Las contradicciones entre ese proyecto y la realidad de la acción de los españoles en las Indias Occidentales conformaron el marco que suscitó las denuncias y las realizaciones teórico-prácticas de los misioneros que, llegados al nuevo continente desde la Península ibérica, iniciaron la TIDH. El reconocimiento de la común dignidad humana será el fundamento para la construcción de un discurso que empleará los derechos humanos universales como instrumento de defensa de los pueblos amerindios y afroamericanos, llevando a su mejor desarrollo las ideas de la Escuela ibérica.

A partir dos pressupostos corpóreos elaborados por Marx nos Manuscritos de 1844, que fundamentam o seu posicionamento materialista-dialético, tais como a teorização antropológica do corpo como unidade dialética entre natureza e história, o conceito-processo de objetivação que requer como condição transhistórica a ligação corpo-terra e a identificação da cisão dessa ligação como a condição histórica de advento da forma social do capital, buscaremos neste artigo analisar a inversão feita pelo jovem Marx da dialética hegeliana. Para tal análise trilharemos o seguinte (...) percurso: 1. Apontaremos os pressupostos corpóreos como conteúdo material da dialética marxiana presente nos Manuscritos de 1844; 2. Analisaremos a crítica do Marx jovem ao idealismo hegeliano a partir do “humano corpóreo” e em acordo com a crítica à economia política; 3. Identificaremos o desdobramento dessa inversão, mantidos os pressupostos, na análise madura de Marx no livro I d’O Capital. (shrink)

In his influential work, A social history of truth, Steven Shapin has argued for the central role of social status in the assessment of experimental knowledge. In his view, in seventeenth-century England, gentlemen were considered the right kind of persons to trust because of their freedom of action, codes of virtue and honour. These characteristics ensured credibility and, hence, compelled assent. However, Shapin does not put sufficient emphasis on the relevance of the testifier’s competence in the validation of knowledge. When (...) and in which circumstances did expertise become more important than social status in the accreditation of natural knowledge? [...] I argue in this paper that it is in the realm of interpretation of unusual and ambiguous anatomies that medical and, in particular, anatomical expertise assumed its most crucial role. Moreover, the medical understanding of the hermaphroditic body in the eighteenth century can be considered one of the most illustrative cases of the construction and display of anatomical expertise. In fact, several of the academic memoirs and dissertations published on hermaphrodites in the eighteenth century attempted precisely to fulfil this purpose. (shrink)

Este artigo tem por objetivo ampliar a compreensão daquilo que Michel Foucault definiu como a “função-psi” e suas influências na instauração do poder. Esse poder se refere ao desenvolvimento de um saber sobre o comportamento humano, cujo conhecimento foi e vem sendo utilizado pelo que Foucault chamou de “normalização” da sociedade. É também objeto deste trabalho buscar o entendimento do “poder disciplinar”, surgido a partir dos estudos do comportamento humano pela Psicologia, para entender como esses estudos promoveram a patologização das (...) experiências individuais. Assim, nasce o que Foucault denominou biopoder: um poder concentrado na figura do Estado e voltado para o gerenciamento da vida e do corpo da população. Um poder disciplinador e normalizador, exercido por meio de tecnologias políticas destinadas a inserir os indivíduos no aparelho de produção. (shrink)

Neste artigo propomos discutir as trajetórias e encruzilhadas de mulheres negras adeptas do catolicismo e do candomblé, a partir da análise subsidiada por epistemologias situadas no campo do Ativismo Negr@, tomando como referência o feminismo negro e decolonial e a teologia feminista católica, procurando captar as narrativas sobre corpo, sexualidade, etnia, raça e religiosidade, de onde emergem intersecções. Para fazermos esse diálogo, contamos com as trajetórias de duas mulheres negras sul baianas, residentes no município de Canavieiras, autodeclaradas negras, com idades (...) de 53 e 62 anos, sendo uma católica e outra candomblecista, respectivamente. As “trajetórias em narrativas” das duas colaboradoras da pesquisa nos revelaram encruzilhadas de pontos de vista sobre corpo e sexualidade, em que a religiosidade norteava a mobilização de diferentes conceitos e representações sobre o gênero. Nesse sentido, o corpo aparece narrado de diferentes formas, sobretudo como ferramenta para o acesso e a manutenção das práticas religiosas, que através da legitimação de elementos sacralizados permitem a efetivação e veiculação de crenças e valores que atravessam o campo da moralidade, afetando, assim, as percepções sobre os desejos e as práticas sexuais de mulheres negras.
