Este livro é uma apresentação das teorias e sistemas da psicologia contemporânea articuladas numa visão de conjunto em que podem ser estabelecidas suas afinidades e incompatibilidades. O texto compõe-se de doze capítulos. O primeiro trata de como se formou o campo específico da psicologia. No segundo, mostra-se como este espaço foi ocupado por diferentes doutrinas cientificistas, românticas e pós-românticas. Os demais capítulos apresentam as matrizes do pensamento psicológico e as teorias de surgimento.

Análise de aspectos do messianismo judaico no pensamento de Benjamin a partir da temática do caos e da redenção. Abordagem do conceito de história, crítica ao progresso, perda da experiência na modernidade e aspectos da linguagem em Benjamin desde a perspectiva das afinidades eletivas entre messianismo e utopia libertária.

This article examined the personal profiles of the Heads of Government of countries in South/North America and how they communicated with their audiences on institutional measures to contain COVID-19. Analyses were carried out on data collected from Twitter from November-2019 to November-2020. This study includes: i)quantitative analysis, measuring categories and emphases in the communication of tweets, retweets, likes, and comments on matters relevant to the pandemic; ii)qualitative analysis that allowed evaluating speeches to identify political interference and the effectiveness of communication (...) at critical moments of the pandemic. It was possible to infer that each president has his singularities and understanding about Social Media’s use as a more direct communication tool with his audience. It was also found that successful communication is not directly proportional to the volume of messages on Twitter, but to socio-political aspects and institutional leadership that can make a difference in Social Media in combating COVID-19.

Philosophy for Children has long been considered as crucial for children’s ethical and moral education and a decisive contribution for education for the democratic life. The book gathers contributions from experts in the field who reflect on fundamental issues on how childhood and ethics are interrelated within the P4C movement. The main interest of this volume is to offer an understanding of how different philosophical conceptions of childhood can be coordinated with different ethical and meta-ethical philosophical considerations in P4C addressing (...) topics such as P4C and relativism, P4C and Virtue ethics, ethics and emotions in P4C, philosophical commitments and P4C application, and Socratic practice within a pragmatist framework. A thought-provoking collection about how assumptions of particular philosophical conceptions of childhood modify moral and ethical education and a testimony of the undeniable contribution of P4C for moral education and reconceptualization of childhood.

Este artigo discute a relação entre a mentira, a verdade factual e a tecnologia. O processo da chamada “mentira organizada”, iniciado no século XX, atualmente assume hoje proporções apocalípticas e foi abordado por Gunther Anders, Paul Virilio e Hannah Arendt, autores cujas reflexões sobre o tema são aqui retomadas e atualizadas em relação ao cenário contemporâneo. São discutidos a relação entre verdade factual e mentira e os efeitos que sobre ela têm a velocidade e o excesso de informações, de imagens (...) e de dados, assim como a visão apocalíptica que Anders, Arendt e Virilio construíram acerca desse processo.

Ao mostrar que não existe ética independente dos interesses fundamentalmente econômicos dos homens, Marx admite que numa sociedade dividida em classes não existe uma ética acima dessas classes. Isso nos leva a inferir que em uma sociedade de classes antagônicas não existe uma noção de felicidade que sirva igualmente para todas essas classes. O que existe é um conceito de felicidade em forma de ideologia que expressa interesses da classe dominante. Assim, o objetivo deste trabalho é discutir o conceito de (...) felicidade, dominante na sociedade capitalista contemporânea, à luz da obra de Karl Marx. Esperamos contribuir, dessa forma, para a constituição de uma noção de felicidade pautad em uma leitura crítica do pensamento de Marx, mesmo que não encontremos em seus escritos, referências explícitas a essa noção.

Este artículo tiene como objetivo presentar un modelo de comprensión tal que permita a la investigación pastoral reflexionar sobre cómo la traditio fidei se puede realizar con el recurso de entornos digitales. Para eso, recurre a la mediología de Régis Debray, reflexionando sobre el modo como los componentes de la cultura digital pueden estar al servicio de la transmisión cultural.

Successful accounts of analogy in law have two burdens to discharge. First, they must reflect the fact that the conclusion of an argument by analogy is a normative claim about how to decide a certain case. Second, they must not fail to accord relevance to the fact that the source case was authoritatively decided in a certain way. We argue in the first half of this paper that the common view of the structure of analogical arguments in law cannot overcome (...) these hurdles. In the second half we develop an original account that aims to succeed where others failed. (shrink)

Several countries maintain universal health coverage, which implies responsibility to organize delivery formats of healthcare services and products for citizens. In Brazil, the health system has a principle of universal access for more than 30 years, but many deficiencies remain and the country observes a day practice for those seeking judicial decisions to determine provision of healthcare.

Introduction: The actions taken by the government to deal with the consequences of the coronavirus diseases 2019 pandemic caused different levels of restriction on the mobility of the population. The need to continue offering physical exercise to individuals after stroke became an emergency. However, these individuals may have barriers to adhere to the programs delivered remotely. There is a lack of evidence related to adherence, attendance, safety, and satisfaction of remote exercise programs for this population.Objective: The aim was to evaluate (...) adherence and barriers to attend a remote physical exercise program for individuals after stroke. We aimed to identify adherence and attendance rate of the remote physical exercise program ; to identify the safety of a remote physical exercise program ; and to identify the overall experience to participate in a remote program.Materials and methods: This is a longitudinal study, including 36 stroke survivors who already attended a face-to-face physical exercise program prior to the COVID-19 pandemic. The remote physical exercise program included sessions for 2 days/week for a duration of 22 weeks, with a total of 44 sessions, which were delivered asynchrony via recorded video sessions. As outcome measures, we performed two questionnaires to identify attendance, barriers, safety, and overall experience related to the program.Results: The adherence rate was 86. The attendance rate was 19, with a total of 8 sessions. The main barriers for lower attendance rate were as follows: lack of motor skills and physical fitness to workout in 80 reports, followed by no exercise companion in 44 reports. The remote physical program has been shown to be safe, and the overall experience was positive from the perspectives of the participants and the family members.Conclusion: Although the adherence rate was high, the attendance rate was low on the remote physical exercise program. The main barriers to attending the program remotely reflect the need of tailoring individually an asynchrony mode of delivering the sessions to individuals after stroke. Our results also indicate how the COVID-19 impacted the health conditions of stroke survivors. The program was safe, and the overall experience indicated a change in the mental, physical, and social health of individuals after stroke and their family members. (shrink)

Apresentaremos as possíveis aplicações pedagógicas das suas reflexões, como a utilização da imprecisão científica de Heisenberg e da concepção de técnica em Heidegger, a partir da análise histórico-filosófica dos seus escritos, tomando-os como fundamentação a necessária e significativa melhoria da educação técnico-científica.

If Unamuno had been able to choose how to be remembered, he would have wanted him to be a poet. This book wants to do justice to that happy possibility. But above all because Unamuno was a poet in the highest sense: he was while writing the same essay as a novel, or theater, letter or verse, and he was also a poet when he passionately lived all the facets of his intense existence. His intellectual work was poetic and his (...) personal relationships, as well as his political activity, also responded to that peculiar Unamunian aesthetic in which the vital horizon is inescapably confused with the tasks of thought." --Translated from back cover.

En rédigeant, à partir des arguments des savants et des amateurs avec qui il était en relation, les Objectiones IIae et VIae aux Meditationes, Mersenne ne pose aucune question concernant le « scepticisme », ni ne voit, dans le doute hyperbolique et dans l’argument du Dieu trompeur, des thèses capables de renouveler ou radicaliser des arguments sceptiques : il n’y a pas, pour Mersenne, de « Descartes sceptique malgré lui ». Nous essayons de tracer quelques étapes du parcours des réflexions (...) de Mersenne autour de ces deux axes thématiques, Dieu trompeur et scepticisme, à partir des années 1620, avec la Vérité des sciences (1625) et la deuxième partie, restée inédite, des Quaestiones in Genesim, et dans les années 1630, avec les Harmonicorum Libri et l’ Harmonie universelle de 1636-1637, pour comprendre pourquoi, en 1641, Mersenne, sans aucune référence au scepticisme, pouvait considérer le problème du Dieu trompeur comme problème essentiellement exégétique qu’il proposait à Descartes en théologien, non « in persona impiorum ». Notre contribution vise à distinguer les sources et le contexte des problèmes discutés par Mersenne, du contexte et des – possibles – sources de Descartes. (shrink)

L’espace esthétiqueLe « renversement du cartésianisme » chez Deleuze et Merleau-PontyCet essai se propose de développer le rapport entre Deleuze et Merleau-Ponty à partir de la tentative des deux philosophes français d’aller au-delà du courantde pensée qu’on pourrait qualifi er, comme le fait Merleau-Ponty lui-même, de « cartésianisme ».Nous commençons notre itinéraire avec la critique que les deux philosophes adressent à la notion cartésienne de « ligne » – passage obligé pour penser, à travers Leibniz et sa notion de « (...) point », la ligne en tant qu’« ensemble de points ». On cherche ensuite à penser une ligne qui ne serait plus tracée dans un espace objectif présupposé, mais plutôt qui « se trace » dans un « espace expressif ».Un tel renversement de la « ligne cartésienne » produit, comme on le verra, des effets qui intéressent également la représentation de la ligne du temps. Émanciper cette dernière du modèle cartésien signifi e la penser par-delà toute référence chronologique, toute dépendance du temps de Kronos. On peut lire dans ce sens la tentative des deux philosophes pour penser le temps de l’événement, le temps de l’Aion. On verra enfin comment, d’un espace et d’un temps anticartésiens, doit naître, pour Merleau-Ponty et Deleuze, une nouvelle grammaire porteuse d’une nouvelle compréhension de la métaphore. Ni l’idée de métaphore proposée par Merleau-Ponty, ni le concept de devenir créé par Deleuze ne concernent une ressemblance fondée sur une identité donnée. Si la métaphore merleau-pontienne et le devenir deleuzien doivent être en mesure de restituer l’essence d’une chose, une telle essence se trouve, ou mieux se crée,à partir d’un mouvement vers « ce que la chose n’est pas ». C’est précisément dans ce sens que Merleau-Ponty lit la métaphore proustienne et que Deleuze cherche à rendre compte des ressemblances créées dans l’oeuvre de Gombrowicz.The Aesthetic SpaceThe “Reversal of Cartesianism” in Deleuze and Merleau-PontyThe present essay proposes to explore the relationship between Deleuze and Merleau-Ponty from the attempt they make to go beyond the current of thought thatwe may qualify, like Merleau-Ponty does it himself, as Cartesianism. We begin our itinerary with the critique that both philosophers direct at the Cartesian notion of the line. The passage through the Cartesian notion of the line is “obligated” in order to think – by means of Leibniz and his notion of point -- the line as a “set of points.” The Cartesian passage is obligated moreover in order to think a line which could no longer be drawn in a presupposed objective space but, rather, which would be “drawn” in an “expressive space.” Such a reversal of the Cartesian line, as we shall see, produces effects that concern also the representation of the line of time. To emancipate the line of time from the Cartesian model means we must think beyond all chronological references, beyond all dependence on the time of Chronos. We are able to read, in this way, both philosophers’ attempt to think the time of the event, the time of Aion. Finally we shall see how, for Merleau-Ponty and Deleuze, a new grammar carrying a new understanding of the metaphor must be born from an anti-Cartesian space and time. Neither the idea of metaphor proposed by Merleau-Ponty nor the concept of becoming created by Deleuze speaks of a resemblance founded upon an identity that is given ahead of time. If Merleau-Ponty’s idea of metaphor and Deleuze’s concept of becoming must be able to produce the essence of a thing, such an essence finds, or better, it iscreated on the basis of a movement toward “what the thing is not.” It is precisely in this sense that Merleau-Ponty reads Proust’s metaphors and that Deleuze will seek to give an account of created resemblances in the work of Gombrowicz.

A intenção deste texto é mostrar que por muito tempo, o negro vindo da África escravizado e os afrodescendentes nascidos no Brasil e no mundo foram adestrados para uma normatização que tentou a todo custo condicioná-los à cultura do colonizador, sem levar em consideração a sua própria cultura, postas a força, através do chicote e da repressão escravistas, amplamente apoiada com o auxílio moralista da igreja e, mais tarde, quando tem acesso a escola formal esta cultura vai ser imposta através (...) de uma espécie de catequismo didático curricular que, sem dúvida, vai ser um dos vários desserviços a nossa tolerância, respeito e aceitação da diferença e que vem a gerar, até os dias atuais atos de características machista, sexista e preconceituosa, promovendo até doenças Foucault. Desta maneira, nossa problemática é como adequar o currículo para nos livrarmos ou diminuirmos estas mazelas. Pra tal empreitada trilharemos o seguinte caminho: Primeiro explicar o paradigma da cientificidade e como ele não dá conta das ciências humanas Kuhn, Figueiredo e nem dos currículos na pós-modernidade Doll Jr. Macedo. Mostrar porque o corpo afrodescendente deve ser educado, a partir de um currículo onde apareça a sua cultura Macedo, Geertz, Laraia e a cultura do outro com o qual se convive uma vez, que a cultura é semiótica e apresenta-se e significa-se de diversas facetas e, ainda, aquele que a estuda a interpreta e descreve alisando as diversas intenções simbólicas contidas na mesma. Procurar propor um currículo que tenha como base a cultura afrodescendente apoiada na mitologia ancestral dos orixás Prandi, Verger e em textos de letras de músicas da MPB que versam sobre sexualidade. PALAVRAS-CHAVE: sexualidade, currículo, cultura, afrodescendente. (shrink)

Resumo Tambor de Mina é o nome da religião afro-brasileira no Maranhão e na Amazônia estabelecida a partir de São Luís desde meados do século XIX. Existem duas casas fundadas por africanos que se continuam: a Casa das Minas Jeje, de origem daomeana e a Casa de Nagô, iorubana de onde derivam a maioria dos terreiros de Mina recentes e atuantes. Trata-se de religião muito ritualizada e discreta, envolvida em segredos e mistérios cuja mitologia é pouco comentada e os (...) rituais muito desenvolvidos. As religiões afro-brasileiras se caracterizam pela realização de festas com transe, danças e comidas que atraem muitos participantes. A comida é bastante para oferecer a todos e distribuir as sobras. A fartura nas festas maiores constitui um dos elementos de prestígio das casas. O texto baseia-se em entrevistas com líderes de um terreiro antigo e de duas casas recentes, sobre comida de santo nas festas. Na linguagem de Mauss o sacrifício constitui obrigação que estabelece uma comunicação entre o mundo sagrado e o profano. O preparo e o consumo da comida de santo permitem conhecer aspectos do sincretismo e dos simbolismos nos rituais. Palavras-chave : Religiões afro-brasileiras; comida de santo; sincretismo; festas; ritual.Tambor de Mina is the name of the Afro-Brazilian religion in Maranhão and Amazon established in São Luís (capital of Maranhão state) since the mid-nineteenth century. There are two matrix-houses founded by Africans: Casa das Minas Jeje , a Dahomean origin house and Casa de Nagô , originally Yoruba and from which most of the Tambor de Mina 's houses come from. It is a very ritualized and discrete religion, involved in secrets and mysteries whose mythology is not frequently commented upon and its rituals are highly developed. Afro-Brazilian religions are characterized by the performance of parties with trance, dance and food which attract many participants. Food is enough to be offered to everyone and have the remains distributed. The abundance of food during the bigger festivities constitutes a prestige element to the houses. According to Mauss, sacrifice is an obligation that establishes communication between sacred and profane. The preparation and consumption of holy feast food allow us to know aspects of syncretism and symbolisms in rituals Keywords : Afro Brazilian religions; holy feast food; syncretism; festivals; ritual.

Logical omniscience states that the knowledge set of ordinary rational agents is closed for its logical consequences. Although epistemic logicians in general judge this principle unrealistic, there is no consensus on how it should be restrained. The challenge is conceptual: we must find adequate criteria for separating obvious logical consequences from non-obvious ones. Non-classical game-theoretic semantics has been employed in this discussion with relative success. On the one hand, with urn semantics [15], an expressive fragment of classical game semantics that (...) weakens the dependence relations between quantifiers occurring in a formula, we can formalize, for a broad array of examples, epistemic scenarios in which an individual ignores the validity of some first-order sentence. On the other hand, urn semantics offers a disproportionate restriction of logical omniscience. Therefore, an improvement of this system is needed to obtain a better solution of the problem. In this paper, I argue that our linguistic competence in using quantifiers requires a sort of basic hypothetical logical knowledge that can be formulated as follows: when inquiring after the truth-value of ∀xφ, an individual might be unaware of all substitutional instances this sentence accepts, but at least she must know that, if an element a is given, then ∀xφ holds only if φ is true. This thesis accepts game-theoretic formalization in terms of a refinement of urn semantics. I maintain that the system so obtained affords an improved solution of the logical omniscience problem. To do this, I characterize first-order theoremhood in US+. As a consequence of this result, we will see that the ideal reasoner depicted by US+ only knows the validity of first-order formulas whose Herbrand witnesses can be trivially found, a fact that provides strong evidence that our refinement of urn semantics captures a relevant sense of logical obviousness.

Este artículo nos adentra en el estudio de la figura de san Martín de Tours, el apóstol de la Galia, cuya influencia se deja sentir en toda Europa, especialmente en España. Se trata del primer santo no mártir después de la paz de Constantino. Resultó ser soldado por fuerza, obispo por obligación, monje por gusto. Representa un nuevo modelo de santidad. De eremita evoluciona a la vida cenobítica, como padre de monjes; y como obispo es el defensor civitatis además del (...) gran evangelizador del mundo rural de la Galia. A su alrededor se generan otros santos. Por otra parte, Tours es la ciudad en que comienza la via turonensis del célebre Camino de Santiago.

The EU Artificial Intelligence Act (AIA) defines four risk categories for AI systems: unacceptable, high, limited, and minimal. However, it lacks a clear methodology for the assessment of these risks in concrete situations. Risks are broadly categorized based on the application areas of AI systems and ambiguous risk factors. This paper suggests a methodology for assessing AI risk magnitudes, focusing on the construction of real-world risk scenarios. To this scope, we propose to integrate the AIA with a framework developed by (...) the Intergovernmental Panel on Climate Change (IPCC) reports and related literature. This approach enables a nuanced analysis of AI risk by exploring the interplay between (a) risk determinants, (b) individual drivers of determinants, and (c) multiple risk types. We further refine the proposed methodology by applying a proportionality test to balance the competing values involved in AI risk assessment. Finally, we present three uses of this approach under the AIA: to implement the Regulation, to assess the significance of risks, and to develop internal risk management systems for AI deployers.

In texts such as “Richard Rorty’s Pragmatic Turn” Jürgen Habermas defends a theory that associates, on the one hand, the truth-claim raised by a speaker for a proposition p with, on the other hand, the requirement that p be “defendable on the basis of good reasons […] at any time and against anybody”. This, as is known, has been the target of criticisms by Rorty, who−in spite of agreeing with Habermas on the central tenet that the way of evaluating our (...) beliefs must be argumentative practice−declares that the only “ideal presupposed by discourse” is “that of being able to justify your beliefs to a competent audience”. We will consider two texts from 1971, -surprisingly neglected in most approaches to the debate-, in which Habermas did include such a “competence condition” to elucidate the notion of truth. We will discuss whether there are good reasons to relinquish such a condition and to refer, instead, only to the formal or procedural properties of argumentative exchanges, as Habermas does in presenting the notion of “ideal speech situation”. As we will try to argue, there are no such good reasons. (shrink)

The present article is framed within the biosemiotic glossary project as a way to address common terminology within biosemiotic research. The glossary integrates the view of the members of the biosemiotic community through a standard survey and a literature review. The concept of ‘semiotic threshold’ was first introduced by Umberto Eco, defining it as a boundary between semiotic and non-semiotic areas. We review here the concept of ‘semiotic threshold’, first describing its denotation within semiotics via an examination on the history (...) of the concept, its synonyms, antonyms, etymology, usage in other languages and context in which it is used. Then we present a general overview of the survey among researchers, analyzing the difference in responses for the concept of ‘lower semiotic threshold’ and related concepts. From the answers we also review the difference between the general usage of ‘semiotic threshold’ versus its specific use within biosemiotics, and attempt to make a general synthesis of the concept taking into account what we have learned from the survey and the literature review.

BackgroundOrgan transplantation represents the most effective and acceptable therapy for end-stage organ failure. However, its frequent practice often leads to a shortage of organs worldwide. To solve this dilemma, some countries, such as Portugal, have switched from an opt-in to an opt-out system, which has raised concerns about respect for individual autonomy. We aimed to evaluate whether young university students are aware of this opt-out system so that they can make informed, autonomous and conscious decisions, as well as to identify (...) the factors that determine a positive attitude toward post-mortem organ donation.MethodsAn observational, cross-sectional study was developed and a questionnaire was administered to first-year students from six faculties of the University of Porto.ResultsOf the 841 participants, 60% were unaware that Portugal had adopted an opt-out system. Among the informed individuals, their main sources of information included social media, internet, and family. Furthermore, only 48% of all participants agreed with the current opt-out system. Female sex (p = 0.049; OR 1.393), knowledge of the law (p < 0.001; OR 4.749) and family being the primary source of information (p < 0.001; OR 2.855) were independent factors associated with a positive attitude toward post-mortem organ donation law.ConclusionsThere is a significant lack of knowledge among young university students regarding the presumed post-mortem organ donation law and how it works. Female sex, having family as a primary source of information and being aware of the presumed post-mortem organ donation law are the strongest independent factors that determine a positive attitude toward the opt-out system.
