The Belnap–Dunn logic is a well-known and well-studied four-valued logic, but until recently little has been known about its extensions, i.e. stronger logics in the same language, called super-Belnap logics here. We give an overview of several results on these logics which have been proved in recent works by Přenosil and Rivieccio. We present Hilbert-style axiomatizations, describe reduced matrix models, and give a description of the lattice of super-Belnap logics and its connections with graph theory. We adopt the point of (...) view ofAlgebraic Logic, exploring applications of the general theory of algebraization of logics to the super-Belnap family. In this respect we establish a number of new results, including a description of the algebraic counterparts, Leibniz filters, and strong versions of super-Belnap logics, as well as the classification of these logics within the Leibniz and Frege hierarchies.

Two famous negative results about da Costa’s paraconsistent logic ${\mathscr {C}}_1$ (the failure of the Lindenbaum–Tarski process [44] and its non-algebraizability [39]) have placed ${\mathscr {C}}_1$ seemingly as an exception to the scope of Abstract Algebraic Logic (AAL). In this paper we undertake a thorough AAL study of da Costa’s logic ${\mathscr {C}}_1$. On the one hand, we strengthen the negative results about ${\mathscr {C}}_1$ by proving that it does not admit any algebraic semantics whatsoever in the sense of Blok (...) and Pigozzi (a weaker notion than algebraizability also introduced in the monograph [6]). On the other hand, ${\mathscr {C}}_1$ is a protoalgebraic logic satisfying a Deduction-Detachment Theorem (DDT). We then extend our AAL study to some paraconsistent axiomatic extensions of ${\mathscr {C}}_1$ covered in the literature. We prove that for extensions ${\mathcal {S}}$ such as ${\mathcal {C}ilo}$ [26], every algebra in ${\mathsf {Alg}}^*({\mathcal {S}})$ contains a Boolean subalgebra, and for extensions ${\mathcal {S}}$ such as,, or [16, 53], every subdirectly irreducible algebra in ${\mathsf {Alg}}^*({\mathcal {S}})$ has cardinality at most 3. We also characterize the quasivariety ${\mathsf {Alg}}^*({\mathcal {S}})$ and the intrinsic variety $\mathbb {V}({\mathcal {S}})$, with,, and. (shrink)

This paper presents a unified framework that explains and extends the already successful applications of the Leibniz operator, the Suszko operator, and the Tarski operator in recent developments in abstract algebraic logic. To this end, we refine Czelakowski’s notion of an S-compatibility operator, and introduce the notion of coherent family of S-compatibility operators, for a sentential logic S. The notion of coherence is a restricted property of commutativity with inverse images by surjective homomorphisms, which is satisfied by both the Leibniz (...) and the Suszko operators. We generalize several constructions and results already existing for the mentioned operators; in particular, the well-known classes of algebras associated with a logic through each of them, and the notions of full generalized model of a logic and a special kind of S-filters. We obtain a General Correspondence Theorem, extending the well-known one from the theory of protoalgebraic logics to arbitrary logics and to more general operators, and strengthening its formulation. We apply the general results to the Leibniz and the Suszko operators, and obtain several characterizations of the main classes of logics in the Leibniz hierarchy by the form of their full generalized models, by old and new properties of the Leibniz operator, and by the behaviour of the Suszko operator. Some of these characterizations complete or extend known ones, for some classes in the hierarchy, thus offering an integrated approach to the Leibniz hierarchy that uncovers some new, nice symmetries.

This paper explores a notion of “the strong version” of a sentential logic S, initially defined in terms of the notion of a Leibniz filter, and shown to coincide with the logic determined by the matrices of S whose filter is the least S-filter in the algebra of the matrix. The paper makes a general study of this notion, which appears to unify under an abstract framework the relationships between many pairs of logics in the literature. The paradigmatic examples are (...) the local and the global consequences associated with a normal modal logic, and the logics preserving degrees of truth and preserving truth associated with certain substructural and many-valued logics. For protoalgebraic logics the results in the paper coincide with those obtained by two of the authors in 2001, so the main novelty of the approach is its suitability for all kinds of logics. The paper also studies three kinds of definability of the Leibniz filters, and their consequences for the determination of the strong version. In a second part of the paper several case studies are developed, comprising positive modal logic, Dunn–Belnap’s four-valued logic, the large family of substructural logics, and some relevance logics.

This note presents some new results from [1] about the Suszko operator and truth‐equational logics, following the works of Czelakowski [11] and Raftery [17]. It is proved that the Suszko operator relative to a truth‐equational logic preserves suprema and commutes with endomorphisms. Together with injectivity, proved by Raftery in [17], the Suszko operator relative to a truth‐equational logic is a structural representation, as defined in [15]. Furthermore, if is a quasivariety, then the Suszko operator relative to a truth‐equational logic is (...) continuous. Finally, it is proved that truth is equationally definable in the class if and only if is a ‐algebraic semantics for and the Suszko operator preserves suprema and commutes with substitutions.

El presente libro se inicia con una breve reflexión sobre la actitud de los intelectuales en América Latina ante la coyuntura actual, señalando las aportaciones y confusiones de su dicurso teórico y tratando de rescatar las formas de expresión del pensamiento crítico; psra esto se considera la vigencia de la dialéctica como lenguaje. Además, se pretende incursionar sobre las relaciones entre individuos y colectivo, y sobre cuestiones metodológicas para el estudio de sujetos sociales; se incorporan el problema de análisis de (...) variables desde la perspectiva de las mediaciones, y una reflexión sobre la lógica del discurso económico para mostrar cómo implica el olvido del sujeto. Constituyen estos trabajos un esfuerzo de aplicación de la postura racional de nuevas posibilidades de reflexión teórica que contribuyan a enriquecer el discurso, aunque conscientes de su carácter todavía exploratorio.

Neste artigo, meu objetivo é analisar de que maneira o cientista, no âmbito das Ciências Naturais, é educado para assimilar, aplicar e articular um determinado paradigma na solução dos problemas de ciência normal, sem colocá-lo (o paradigma) criticamente em questão, assim qualquer erro que venha a ocorrer na pesquisa é atribuído ao cientista e não ao paradigma. Pretendo também, mostrar que o caráter dogmático do paradigma não permite que o cientista desenvolva pesquisas visando novas descobertas que não se enquadrem nos (...) parâmetros ditados pelo mesmo, tal atitude exige total aceitação e comprometimento da comunidade científica para com o paradigma aceito, gerando assim, uma espécie de profissão de fé na capacidade do paradigma em resolver os quebra-cabeças que se apresentam na prática da ciência normal.

ABSTRACT In this research,1 we aim to analyze how misogyny establishes itself in an interaction on X (formerly Twitter) to legitimize hate speech, under the argument of opinion defense. Theoretically, in light of Interactional Sociolinguistics and Pragmatics, we conceive that impoliteness strategies contribute to the construction of linguistic-discursive violence scenarios in online-mediated interactions, as they both reduce interlocutive distance and generate sexist, misogynistic, patriarchal, and antifeminist metapragmatics. Methodologically, we adopted a qualitative approach to analyze an interaction on X based on (...) the inclusion and exclusion criteria proposed in this study, using the netnographic method. Analytically, we observed that interlocutors C, E, and F frequently used impoliteness strategies in constructing opinion-based discourses to attack feminism and legitimize hate speech. (shrink)

lts early roots reaching as far as 1954, the great Buropean Post War Conference, which lasted three years from 1972 to 1975, had to overcome the vicissitudes of the Cold War and the setbacks of thediplomatie normalization between Bast and West afterwards, before taking its final shape. Hence the multiple changes of its characteristics and purposes over the years.Resulting from a global rapprochement between the Super Powers and a cautious modus vivendi between the German twin States in Burope, the CSCB, (...) although an old Russian dream, was finally seen by the other parties as a calculated risk and possibly a beneficial one.In the end, Western scepticism and criticism of the Helsinki Final Act were less founded on the actual outcome then on traditional reluctance towards the Bast and more vocal because of a darkening international outlook : the deepening economie crisis, the political disarray in Southern Burope and a disheartened public opinion.A more sober view might nevertheless appreciate not only the balance of modest mutual gains for all participants, but moreover the outline and hope for a «rebirth of Europe's historical identity» as well as the first diplomatic acceptance of the BBC-entity and last, but not least, the «inevitability of reason», as expressed in the policy of détente and the general «vested interest» in it.

This collection of essays examines the ways in which disputes and controversies about the application of scientific knowledge are resolved. Four concrete examples of public controversy are considered in detail: the efficacy of Laetrile, the classification of homosexuality as a disease, the setting of safety standards in the workplace, and the utility of nuclear energy as a source of power. The essays in this volume show that debates about these cases are not confined to matters of empirical fact. Rather, as (...) is seen with most scientific and technical controversies, they focus on and are structured by complex ethical, economic, and political interests. Drs. Engelhardt and Caplan have brought together a distinguished group of scholars from the sciences and humanities, who sketch a theory of scientific controversy and attempt to provide recommendations about the ways in which both scientists and the public ought to seek more informed resolutions of highly contentious issues in science and technology. Scientific Controversies is offered as a contribution to the better understanding of the roles of both science and nonscientific interests in disputes and controversies pertaining to science and technology.

Nursing research using concept analysis plays a critical role for knowledge development, particularly when concerning to broad and foundational concepts for nursing practice, such as dignity. This study aimed to synthesize research concerning concept analysis of dignity in nursing care. Based on a literature review, electronic databases were searched using the terms “dignity,” “human dignity,” “concept analysis,” and nurs*. Papers in Portuguese or English were included. The research synthesis was conducted independently by two reviewers. A total of 35 citations were (...) identified and seven papers were included. Six studies were elected using Walker and Avant concept analysis methodology while one applied the Beth Rodgers evolutionary model. The concept of dignity has been studied by nurses, and its attributes, antecedents, consequences, and similar concepts were synthesized into a definition. Dignity emerged as a fundamental concept in nursing ethics and the main attributes synthesized were personhood, sociability, respect, and autonomy. The antecedents identified were: facilitators—patient focus care, recognition, education, and ethical competence; threats—vulnerability and organizational environment. The consequences were positive coping, empowerment, and dignity preservation. The synthesis of these seven studies using concept analysis provided a clear definition of dignity. These findings challenge future research and education, particularly for the study of undergraduate and postgraduate nursing education programs to enhance skills for preserving patient dignity in clinical practice.

O liberalismo português iniciou o seu longo período de implantação com a Revolução de 24 de Agosto de 1820 e com a aprovação, dois anos depois, da Constituição de 1822, a primeira lei fundamental do país, que deu começo à construção do seu Estado de Direito. Nos dezoito anos seguintes, Portugal aprovaria mais duas constituições (1826 e 1838), correspondendo, cada uma delas, a um paradigma do constitucionalismo liberal de oitocentos. Por essa razão o estudo deste período torna-se particularmente relevante para (...) o conhecimento do liberalismo constitucional, não somente de Portugal, mas de todo o século XIX europeu. (shrink)

The scientific community has debated the importance of “return” activities after ethnobiological studies. This issue has provoked debate because it touches on the ethics of research and the relationships with the people involved in these studies. This case study aimed to investigate community perception of an ethnobotany research project that was carried out in the semi-arid region of northeastern Brazil. Furthermore, we reported how the residents of this rural community felt about participating in the activities of “return” that arose from (...) the projects. Our findings demonstrate that “return” activities should be planned from the design phase of the research until its closure as a lifelong process that allows the communities involved to gradually take ownership of the information and actions that are being generated. Similarly, we argue that such activities must be negotiated with the people of the community so that they have decision-making power and autonomy to decide what is most relevant to their lives.

Nietzsche's impact on the world of culture, philosophy, and the arts is uncontested, but his political thought remains mired in controversy. By placing Nietzsche back in his late-nineteenth-century German context, Nietzsche's Great Politics moves away from the disputes surrounding Nietzsche's appropriation by the Nazis and challenges the use of the philosopher in postmodern democratic thought. Rather than starting with contemporary democratic theory or continental philosophy, Hugo Drochon argues that Nietzsche's political ideas must first be understood in light of Bismarck's (...) policies, in particular his "Great Politics," which transformed the international politics of the late nineteenth century. Nietzsche's Great Politics shows how Nietzsche made Bismarck's notion his own, enabling him to offer a vision of a unified European political order that was to serve as a counterbalance to both Britain and Russia. This order was to be led by a "good European" cultural elite whose goal would be to encourage the rebirth of Greek high culture. In relocating Nietzsche's politics to their own time, the book offers not only a novel reading of the philosopher but also a more accurate picture of why his political thought remains so relevant today. -- from dust jacket.

This article addresses the topic of artistic mímēsis, and attempts to illuminate the contemporary discussion between two seemingly irreconcilable positions. The first, framed in a traditional interpretation of Aristotelian texts, considers the work of art as an imitation of nature, finding in it its only rule. The second, supported by a different interpretation, states that, according to Aristotle himself, artistic creativity is fictional, that is, independent of natural reality, and therefore debtor only of the artist’s subjectivity. However, when considering the (...) analogy between téchnē and phýsis, within Aristotle’s teleological worldview, it is possible to notice a kind of “common work” that harmonizes them. In this context, and advancing on the consideration of the mimetic poiésis, the philosopher’s texts allow an interpretation that, without detaching itself from the original naturalness of art and taking it as a guide, opens the horizon to the artist’s creativity.

There are relatively few empirical studies on the impacts of corporate social responsibility policies and programs. This article addresses the research gap by analyzing the incidence of, and the conditions that affect, decoupling among CSR policies, implementation of CSR programs, and CSR impacts for various environmental and social issues. Complete decoupling is a condition of full divergence among policies, programs, and impacts amounting to purely ceremonial CSR. Using ratings from a sustainability rating agency on a sample of about 1,000 large (...) companies in 24 countries, the authors find empirical evidence not supporting a conclusion of complete decoupling. The empirical evidence suggests four levels of nondivergence in the sample. First, for most CSR issues examined, CSR policies of high quality do have relatively strong effects on CSR implementation. Second, CSR programs of high quality do have relatively strong effects on CSR impacts. Third, for most CSR issues, even low-quality CSR policies enforce the incidence and quality of programs in comparison with having no policy at all. Fourth, weak programs have more impact on the realization of CSR goals than having no program at all. The authors also find that the quality of CSR reporting and locating the responsibility for CSR at the board level reduce decoupling by strengthening the quality of CSR programs. (shrink)

O presente trabalho objetiva fazer uma análise sobre algumas das principais temáticas elaboradas pelo pensador argentino Luis Alberto Warat, quais sejam: o antropofagismo waratiano, o reencontro com a subjetividade perdida e a carnavalização. Para isso, analisou- se uma das obras mais caras do pensamento waratiano: A ciência jurídica e seus dois maridos. Buscou-se através da análise empreendida, elaborar uma crítica sobre paradigmas tradicionais de ciência, incluindo aqui, a própria Ciência do Direito. Sobreleva-se o caráter de indisciplina das atividades artístico-literárias para (...) insinuar as falhas históricas das disciplinas bem instituídas, do pensamento e da cultura dominantes. Visa-se, portanto, maior interação entre aquilo que se entende como ciência e a subjetividade humana como um todo. (shrink)

O objetivo deste artigo é pensar como a relação entre o mundo dos antepassados e o mundo dos vivos se estabelece e se estrutura por intermédio do ritual de ukanyi. Proposta esta que remete ao estudo e compreensão da religiosidade tradicional africana, na qual se assenta a cosmovisão dos africanos perpassada por um sistema de valores, crenças e práticas bantu. Assim, o método etnográfico e a análise situacional aparecem como alicerces para compreender o fenômeno em causa. Considero o pressuposto de (...) que o ritual de ukanyi é uma cerimônia que permite a exaltação dos antepassados, ativa e reativa valores, crenças e práticas que fortalecem e revigoram a religiosidade tradicional africana. Dessa forma, o mesmo nos possibilita vivenciar e experimentar dois mundos diferentes, dos vivos e dos mortos. Entendo que compreender a relação entre o mundo dos vivos e dos antepassados é adentrar na forma como se constituem as afrofilosofias que permitem tangenciar o universo africano. Palavras chave: Ritual de ukanyi. Mundo dos vivos. Mundo dos mortos. Antepassados. (shrink)

This essay offers a fresh interpretation of Bhartr̥hari’s concept of “insight”, and of its identification as the object of a sentence in the second kāṇḍa of the Vākyapadīya. Earlier scholars dealing with this topic disagreed on three main points: whether an epistemologically rigorous concept of insight can be found in Bhartr̥hari’s work, or if the notion remains irrevocably vague and equivocal; whether the concept of pratibhā primarily belongs to linguistics, or to action theory; whether Bhartr̥hari’s identification of insight as the (...) object of a sentence should be taken literally or figuratively. Starting from a close analysis of all passages in Bhartr̥hari’s work mentioning pratibhā, I identify, first of all, a univocal understanding of insight, valid throughout the Vākyapadīya, as immediate cognition informed by verbal transmission, in other words as a form of practical knowledge, non-representational yet essentially productive and dynamic. Showing, on this basis, how Bhartr̥hari’s understanding of language at the level of sentences is pragmatic rather than referential, I demonstrate, against the view prevalent in the late grammatical tradition, that a literal interpretation of his provocative statement on pratibhā as vākyārtha remains perfectly plausible. This thesis is further corroborated by the consideration of post-Bhartr̥hari philosophical sources elaborating on his ideas, which allow us better to understand in what sense pratibhā can legitimately be thought of as cognition “without an object”.

Neste texto procuramos traçar os contornos do que estamos considerando como um campo de investigação, ainda que em construção, situado na interface entre duas áreas de conhecimento: a educação e a religião. Tem como objetivo refletir sobre os sentidos da educação, de modo a evidenciar as práticas religiosas como instâncias de educação e formação de subjetividades. Metodologicamente, trata-se de uma reflexão de natureza teórico-bibliográfica inspirada em autores como Brandão (2002), Libâneo, (2010), Albuquerque; Buecke (2019), e outros. Para tanto, apresentamos (...) um mapa das produções intelectuais ancoradas tanto no curso de graduação em Ciências da Religião, quanto no Programa de Pós-Graduação em Educação, ambos situados na Universidade do Estado do *Pará (UEPA), instituição que tem se destacado no fomento a esse universo investigativo. Dentre as considerações, apontamos a educação não escolar como um conjunto de processos formativos, fincados na cultura, que atuam na tradução da realidade concreta, ocupando diferentes espaços, temporalidades e intensões por meio das quais diferentes agentes, humanos ou não, reinventam a educabilidade.
