We introduce a multimodal logic for order of magnitude reasoning which considers a new logic-based alternative to the notion of closeness, we provide an axiom system and prove its soundness and completeness.

En este artículo llevamos a cabo una extensa revisión de la literatura científica en lo relativo a los vínculos entre materialismo y felicidad, desde un enfoque multidisciplinar que incluye la psicología, la comunicación, la economía y la ética. La línea dominante en la bibliografía insiste en vincular un mayor materialismo con una menor auto-percepción de felicidad y de bienestar, y con una mayor propensión a la depresión. En esta revisión atendemos a los aspectos que así lo evidencian, al rumbo actual (...) de las investigaciones y a los retos aún pendientes de clarificación por parte de la comunidad investigadora.

In the article, we carry out a theoretical reflection on the contributions of Paulo Freire's pedagogy. Given the diversity of themes that Freire covers, we make a first approach to his pedagogical-political thought and for this we do it through a brief biographical journey through the main life stages of the author. The great Brazilian educator was a person who had a special concern for the other, for denouncing injustices and for showing us that human beings have in our hands (...) the possibilities of change and transformation. In order to address all these questions, according to Freire, it is necessary to do so from a critical reading of the world in which we live. To delve deeper and understand essential aspects of his life and also of his work, we do so with people close to the author who have had the opportunity to live and work with him and know, in depth, his pedagogical legacy. As a result of this journey through his pedagogical work, we offer some reflections that invite us to look at the validity and timeliness of his approaches. Freire's pedagogy proposes a critical reading of the world that does not generate hopelessness, but rather allows us to see the resistance, the ways to get ahead, the construction of the new, the permanent possibilities that human beings have to rebuild our lives. Freire spoke of hope as an inherent issue in teaching practice, remembering, at the same time, that change, although difficult, is possible. (shrink)

ABSTRACT In this paper we present a new semantic approach for propositional linear temporal logic with discrete time, strongly based in the well-order of IN (the set of natural numbers). We consider temporal connectives which express precedence, posteriority and simultaneity, and they provide a family of expressively complete temporal logics. The selection of the new semantics and connectives used in this work was principally to obtain a suitable executable temporal logic, which can be used for the specification and control of (...) process behaviour in discrete time in a similar way to thai presented by D. Gabbay in [GAB 89], Our new approach has two advantages: firstly, the connectives are defined intuitively so that they have interpretations which relate to properties of interest in real systems; secondly, it provides a new semantics that facilitates simpler proofs of many valid formulas and metatheorems. To confirm this second advantage, we use our semantics to give a formal proof of the Separation Theorem for one of these logics (specifically LN3). The great interest of this Separation Theorem for the executable temporal logic is emphasised by D. Gabbay in [GAB 89], [GAB 88]. (shrink)

In this paper, we focus on a logical approach to the important notion of closeness, which has not received much attention in the literature. Our notion of closeness is based on the so-called proximity intervals, which will be used to decide the elements that are close to each other. Some of the intuitions of this definition are explained on the basis of examples. We prove the decidability of the recently introduced multimodal logic for closeness and, then, we show some capabilities (...) of the logic with respect to expressivity in order to denote particular positions of the proximity intervals.

The present article presents brief notes on the "new thought" of the German philosopher Franz Rosenzweig, in the work The Star of Redemption, with the exposure of reason and its totalitarian and violent vocation, which, since Antiquity until Modernity, was based on the tireless search for knowledge of the All, in its essence, with the formulation of concepts, in a closed experience. In contrast, the philosopher from Kassel points out his proposal for a new philosophical system, with a vocabulary similar (...) to the one found in Jewish theology, even being confused with theological thought, which revealed an alternative analysis of experience (open, dynamic, relational and in time), the construction of a plural reason, admitting and respectingplurality.

Combining modalities has proven to have interesting applications and many approaches that combine time with other types of modalities have been developed. One of these approaches uses accessibility functions between flows of time to study the basic properties of the functions, such as being total or partial, injective, surjective, etc. The completeness of certain systems expressing many of these properties, with the exception of surjectivity, has been proven. In this paper we propose a language with nominals to denote the initial (...) and final sets of each function in a model in order to obtain a complete system for reasoning about surjective partial functions.

Este texto trata das questões regionais que emergem a partir do momento em que o Brasil se torna uma nação independente. É a própria luta entre as distintas parcelas das elites, que se distribuem por distintas porções do território e tem nelas assentadas seus interesses políticos e econômicos, para dar as diretrizes da nação emergente, que leva ao surgimento de reivindicações, ações e discursos de cunho regionalista, alguns deles chegando a radicalidade da proposição da secessão. É a luta em torno (...) de hegemonizar a nação que leva emergência das regiões. O artigo faz um percurso em torno do tema da formação territorial brasileira e de como as questões regionais se colocam nesse processo de configuração do espaço nacional. (shrink)

The confinement of the population into their homes as a result of COVID-19 has entailed a notable increase in the consumption of diverse media. This exploratory study aimed to examine how the increase in media consumption was related to subjective happiness and psychological well-being. For this purpose, a questionnaire was administered to a sample of Spanish adults to assess their consumption of different media before and during confinement. Moreover, participants were evaluated for hedonic, eudaimonic, social, and experienced happiness by using (...) the Pemberton Happiness Index. The results underlined the great increase in the consumption of TV for entertainment and social networking sites during confinement. Furthermore, it was found that higher consumption was negatively correlated with the level of happiness, so that, people who reported greater well-being, both subjective and psychological, spent less time watching TV and using SNS. In contrast, no association was found between the level of happiness and the consumption of news and radio. Therefore, it seems that far from cultivating greater happiness, those who engaged in heavy consumption of TV entertainment and SNS during confinement were less happy than those who did so more moderately and spent more time using other media or performing other activities.

O presente trabalho visa expor, utilizando dupla perspectiva, as tecnociências e suas inovações como resultantes do modo de produção capitalista e no que isso implica. Num primeiro momento, será apresentada a perspectiva utilizada por Deuleuze e Guattari em Mil Platôs para denotar a importância do Estado como garantidor de um modo de produção e como agenciador, via ordem jurídica, das linhas de fuga que emergem da sociedade, inclusive no que toca às inovações trazidas pelo desenvolvimento e ampliação dos conhecimentos e (...) dos saberes. Na sequência, de forma complementar, serão abordados o capitalismo em si e alguns de seus fundamentos relevantes para a compreensão das consequências possíveis para as inovações tecnocientíficas, isso a partir de postulados da teoria materialista-histórica. Após, irá se procurar demonstrar a realização de um estatuto ético-jurídico brasileiro como agenciamento das modificações e inovações que dizem com uso de células tronco para pesquisas. (shrink)

Colombia is now projecting a new, positive image to the world after over­coming a past characterised by politically inspired guerrilla warfare and violent conflict with narco-trafficking cartels which had ravaged the country for decades. Even before the country’s transformation, other intermediate place institutions – cities and regions – had already taken significant steps towards territorial change and marketing. This paper outlines the processes involved in urban and social transformation in the city of Medellín and in the marketing of the coffee (...) region, as illustrative cases of city re-brand­ing and regional branding, respectively.

Entendo a partidarização judicial como agravamento do anti-igualitarismo jurídico que degrada o formalismo democrático. Atenho-me ao Brasil, sem generalizar: há pessoas dignas no judiciário. Falo na aplicação indevida da lei na esfera política para impedir mudanças na sociedade. Trato o tema em três níveis. Preliminarmente, discuto a desigualdade político-jurídica, depois os golpes de Estado, e por fim o manejo da legislação como arma política que mantém injustiças.

Según la doctrina subjetiva, el significado y el contenido de las disposiciones jurídicas depende de la intención legislativa que las creó. Este método es discutible por varias razones, entre ellas la dificultad de identificar las intenciones legislativas que tienen relevancia para la interpretación. Un aspecto de la dificultad es que en una disposición pueden confluir muchas intenciones diferentes. El objeto del trabajo es catalogar y discutir una serie de intenciones legislativas potenciales cuya respectiva importancia ha de determinar la doctrina subjetiva. (...) Esta diversidad de intenciones se debe tanto a su procedencia como a su contenido y alcance. El trabajo examina primero de quién pueden ser las intenciones legislativas y a continuación cuáles pueden ser. (shrink)

This article aims to revisit the second essay of Nietzsche’s Genealogy of Morals, in order to show some aesthetic-theoretical assumptions present in his genealogical investigation on memory and suffering. Central to the purposes of this analysis is Homer’s role, more precisely, the artistic strategies and procedures of his poetics.

Résumé Si le renouveau de l’humanisme passe par le rapprochement des différences, les perspectives occidentale et orientale sur le monde divergent : la première se repère dans l’Histoire et la seconde dans la notion de destin.

In previous works, we presented a modification of the usual possible world semantics by introducing an independent temporal structure in each world and using accessibility functions to represent the relation among them. Different properties ofthe accessibility functions have been considered and axiomatic systems which define these properties have been given. Only a few ofthese systems have been proved tobe complete. The aim ofthis paper is to make a progress in the study ofcompleteness for functional systems. For this end, we use (...) indexes as names for temporal flows and give new proofs of completeness. Specifically, we focus our attention on the system which defines injectivity, because the system which defines this property without using indexes was proved to be incomplete in previous works. The only system considered which remains incomplete is the one which defines surjectivity, even ifwe consider a sequence ofnatural extensions ofthe previous one. (shrink)

Argument evaluation, one of the central problems in argumentation theory, consists in studying what makes an argument a good one. This paper proposes a formal approach to argument evaluation from the perspective of justification logic. We adopt a multi-agent setting, accepting the intuitive idea that arguments are always evaluated by someone. Two general restrictions are imposed on our analysis: non-deductive arguments are left out and the goal of argument evaluation is fixed: supporting a given proposition. Methodologically, our approach uses several (...) existing tools borrowed from justification logic, awareness logic, doxastic logic and logics for belief dependence. We start by introducing a basic logic for argument evaluation, where a list of argumentative and doxastic notions can be expressed. Later on, we discuss how to capture the mentioned form of argument evaluation by defining a preference operator in the object language. The intuitive picture behind this definition is that, when assessing a couple of arguments, the agent puts them to a test consisting of several criteria. As a result of this process, a preference relation among the evaluated arguments is established by the agent. After showing that this operator suffers a special form of logical omniscience, called preferential omniscience, we discuss how to define an explicit version of it, more suitable to deal with non-ideal agents. The present work exploits the formal notion of awareness in order to model several informal phenomena: awareness of sentences, availability of arguments and communication between agents and external sources. We discuss several extensions of the basic logic and offer completeness and decidability results for all of them. (shrink)

English translates ‘genos’ as kind and ‘eidos’ as form, which differ in meaning as much as ‘herd’ and ‘brand’ do. But there are hard passages where ‘genos’ and ‘eidos’ have appeared to be synonyms, usually given the new meaning class. We show that, although ‘genos’ and ‘eidos’ are never synonyms and continue to mean kind and form, the word ‘eidos’ can be used figuratively, as a metonym, for a genos.

This chapter focuses on one of the common fallacies in Western philosophy: hasty generalization (HG). HG is committed when some aspect of the definition of the proper generalization is violated. In other words, the “hasty” aspect of this fallacy is triggered either when there is a lack of knowledge of the selected sample or when the selected sample is not representative of the whole group, or when both and are true. We see HG committed just about every day in politics (...) and the media. In politics, HGs are used to emphasize the extremes of a particular viewpoint. Concurrently, HG is used quite often by advertisers to promote a particular product. To avoid committing this fallacy, the arguer should take into consideration the amount of justifiable knowledge one might have on a particular subject and whether the selected sample being used in the case is justifiably representative of the group in question.

Steinman indicates that his ability to understand beauty is limited by his imagination. Beauty, as it has been traditionally defined, is an ultimate value, an ideal on same level as truth and goodness. Many of the ancient Greeks believed that symmetry represented order, and order was beautiful because it revealed a type of cosmic justice and truth that no person could deny. So, when Steinman's application of beauty comes into play, he is definitely emphasizing the order and justice that beauty (...) provides. The player of BioShock is introduced to a world quite familiar to ours, not necessarily in sense of Rapture, underwater cities, or vintage décor, but rather in the form of worldview. The vending machines are not coincidentally called Circus of Values. As players, one have value in surviving (intrinsic) so one will do whatever one can to survive, including buying or hacking vending machines with supplies (extrinsic value). (shrink)

This chapter focuses on one of the common fallacies in Western philosophy called the slippery slope. According to Patrick Hurley in A Concise Introduction to Logic, “the fallacy of slippery slope is a variety of the false cause fallacy. It occurs when the conclusion of an argument rests on an alleged chain reaction and there is not sufficient reason to think that the chain reaction will actually take place”. The key term in the chapter is “chain reaction”. If all of (...) the events in the chain reaction can be justified, then the slippery slope is not committed. But the nuances and intricate improbable connections between each event still make it difficult to support the ultimate conclusion, which is to get rid of cable. The chapter discusses two simple techniques in order to avoid committing the slippery slope fallacy. (shrink)

If the revival of humanism depends on closing the gap between differences, western and eastern perspectives on the world diverge: the first uses History as its guide and the second uses the notion of destiny. Between the logical power of western instrumental rationalism and the affective power of the feeling modes of knowledge like liturgy and music, the West should be able to accept difference and reject both closed identities and absolute alterities.

A common approach for measuring the effectiveness of an education system or a school is the estimation of the impact that school interventions have on students’ academic performance. However, the latest trends aim to extend the focus beyond students’ acquisition of knowledge and skills, and to consider aspects such as well-being in the academic context. For this reason, the 2015 edition of the international assessment system PISA incorporated a new tool aimed at evaluating the socio-affective variables related to the well-being (...) of students. It is based on a definition focused on the five dimensions proposed in PISA theoretical framework: cognitive, psychological, social, physical and material. The main purpose of this study is to identify the well-being components that significantly affect student academic performance and to estimate the magnitude of school effects on the well-being of students in OECD countries, the school effect being understood as the ability of schools to increase subjective student well-being. To achieve this goal, we analyzed the responses of 234,000 students from thirty-five OECD countries to PISA 2015 questionnaires. Specifically, we considered non-cognitive variables in the questionnaires and student performance in science. The results indicated that the cognitive well-being dimension, composed of enjoyment of science, self-efficacy and instrumental motivation, as well as the test anxiety all had a consistent relationship with student performance across countries. In addition, the school effect, estimated through a two-level hierarchical linear model, in terms of student well-being was systematically low. While the school effect accounted for approximately 25% of the variance in the results for the cognitive dimension, only 5-9% of variance in well-being indicators was attributable to it. This suggests that the influence of school on student welfare is weak, and the effect is similar across countries. The present study contributes to the general discussion currently underway about the definition of well-being and the connection between well-being and achievement. The results highlighted two complementary concerns: there is a clear need to promote socio-emotional education in schools, and it is important to develop a rigorous framework for well-being assessment. The implications of the results and proposals for future studies are discussed. (shrink)

O presente artigo busca apresentar a perspectiva do jovem Nietzsche em Verdade e mentira em sentido extramoral, segundo a qual o sentido moral de verdade é construído a partir de convencionalização e regulamentação das práticas e dos usos dossignos linguísticos. Para cumprir essa tarefa, pretende-se dividir o texto em três argumentos principais: Nietzsche e o estatuto da linguagem natural para o pensamento filosófico: metáfora como fator subjetivo da significação, uso e significação: a construção interpessoal do sentido moral de verdade e (...) o que é moral no registro do simples pensar?

O objetivo do presente artigo, pensado preliminarmente como parte integrante de um estudo mais amplo e sistemático sobre o processo de formação do pensamento do jovem Nietzsche, é discutir o estatuto da linguagem em suas considerações sobre estética, notadamente naquela apresentada nos fragmentos, apontamentos e escritos póstumos preparatórios d’ O Nascimento da Tragédia . Como se poderá notar, o viés de investigação proposto, respaldado em importantes estudos de literatura secundária, primou por uma esmerada, porém não exaustiva, reconstituição do trinômio: linguagem (...) sonora ( Tonsprache ), linguagem-de-gesto ( Geberdensprache ) e linguagem-de-palavra ( Wortsprache ), que margeia a investigação nietzscheana sobre a origem, desenvolvimento e perecimento da tragédia grega.

O objetivo deste artigo é interpretar de modo heterodoxo algumas polêmicas afirmações de Nietzsche no segundo ensaio de sua obra Para a genealogia da moral, mais precisamente, aquelas que fazem enfática apologia aos fenômenos da crueldade e violência humanas enquanto pilares de toda cultura superior. Por heterodoxo, eu entendo aqui um modo de proceder estético no trato desses fenômenos, algo que é disseminado também em outras obras.

A dilemma has stymied interpretations of the Stranger’s method of dividing kinds into subkinds in Plato’sSophistandStatesman. The dilemma assumes that the kinds are either extensions or intensions. Now kinds divide like extensions, not intensions. But extensions cannot explain the distinct identities of kinds that possess the very same members. We propose understanding a kind as like an animal body—the Stranger’s simile for division—possessing both an extension and an intension. We find textual support in the Stranger’s paradigmatic four steps for collecting (...) a subkind. (shrink)

This study focuses on a news framing analysis of Latin America and Latin Americans in the Spanish press. For this purpose 1,271 news articles with different Latin American countries or their citizens as main actors were examined. These news stories had been published by the main Spanish newspapers in 1999. The results reveal that attribution of responsibility, human interest, and conflict constitute the prevailing frames used by the Spanish press. Furthermore, significant differences in the considered variables in terms of main (...) country actor were observed. Venezuela and Colombia, in particular, are associated with armed conflicts, natural disasters, crimes, and accidents using human interest and conflict news frames. This leads to a necessary consideration of the consequences this type of news coverage on Latin America may generate, and whether it will reinforce stereotypes or prejudices in the Spanish audience against peoples from these countries, especially those with a high migratory influx to Spain.

This paper presents the design, simulation, and experimental verification of the fractional-order multiscroll Lü chaotic system. We base them on op-amp-based approximations of fractional-order integrators and saturated series of nonlinear functions. The integrators are first-order active realizations tuned to reduce the inaccuracy of the frequency response. By an exponential curve fitting, we got a convenient design equation for realizing fractional-order integrators of orders from 0.1 to 0.95. The results include simulations in SPICE of the mathematical description and the electronic implementation (...) and experimental measurements that confirm them. Monte Carlo and sensitivity tests revealed a robust realization. Contrary to its passive counterparts, the suggested realizations significantly reduce design and implementation efforts by favoring resistors and capacitors with commercial values and reducing hardware requirements.

No Íon, a autoridade e a sabedoria de poetas e rapsodos são confrontadas por meios indiretos. O caráter oblíquo dessa estratégia impede o acesso direto ao conteúdo do diálogo e provoca inúmeros equívocos de leitura. Um fato contextual estimula mais ainda leituras equivocadas. A poesia tratada no Íon difere muito da forma como nós, modernos, a entendemos. Na Antiguidade grega, de base aural, a poesia era o modo privilegiado de conservação da tradição herdada, e permaneceu exercendo essa função capital até (...) mesmo quando a escrita passou a desempenhar papel relevante na forma de composição e transmissão cultural. Neste contexto, o rapsodo representa uma autoridade que cobre praticamente todos os campos do saber. Autoridade enciclopédica, contra a qual Platão travou uma guerra não sem ambiguidades. O presente artigo busca revelar a motivação profunda que anima o Íon: a contraposição entre dois modos de comunicação, o da poesia e o da filosofia. Defende, ainda, que Platão, ao atacar a performance poética, busca, além de rejeitá-la, substituí-la pelo élenkhos socrático como modo de comunicação ideal para instrução e guia da vida humana.

Algunos filósofos utilitaristas justifican proteger los derechos humanos por la utilidad que reportan, pero niegan que tal obligación pueda desplazar al deber ético más fundamental de procurar el bienestar.

A partir de esta idea se discute la suficiencia de una ética basada únicamente (...) en derechos, los conflictos de los derechos humanos entre sí y con otros bienes morales y la justificación de la inalienabilidad de los derechos humanos.

Educar na diferença pressupõe respeitar as diversas vozes dos sujeitos da escola, a fim de que, sociocognitivamente, estudantes e professores construam saberes, partilhando experiências, socializando conhecimentos e refletindo sobre seus modos de ver/conceber as coisas do mundo. Por essa razão, o professor de língua portuguesa precisa estar atento aos modos de compreensão que seus alunos revelam quando produzem dizeres nas atividades realizadas em sala de aula. Para isso, é preciso assumir que os sentidos são sempre negociados, e que os sujeitos, (...) quando focalizam um conteúdo assumindo-se como enunciadores de um dizer, manifestam, ao mesmo tempo, o dialogismo presente em toda ação de linguagem. Esse dialogismo pode ser testemunhado pelos indícios de alteridade presente nas produções textuais dos estudantes. Para comprovar isso, este trabalho desenvolve análise de textos argumentativos produzidos por alunos do Ensino Médio, comentando os objetos de discurso presentes nessas produções textuais. Dessa forma, busca evidenciar que, além de serem reveladores de pontos de vista, os objetos de discurso sinalizam o diálogo do enunciador com outros sujeitos, exercendo papel central na construção da orientação argumentativa do texto. Nessa perspectiva, considera-se que a construção do ponto de vista ocorre, em muitos casos, pela adesão do enunciador às ideias e opiniões de outros sujeitos; o que confirma o principal argumento orientador deste trabalho: para construir opinião, o enunciador reformula o próprio dizer, ora por adaptações de sua própria voz, ora por influência de outros dizeres com os quais dialoga durante o desempenho da atividade verbal. Palavras-chave: Referentes textuais. Intersubjetividade. Orientação argumentativa. (shrink)
