A evolução dos meios de comunicação propiciou um massivo fluxo informacional, trazendo consigo alguns entraves. O fenômeno das fake news é produto dessa mudança na sociedade, afetando de diversas formas a vida das pessoas e inclusive a possibilidade de uma escolha plena e livre de influências, sua liberdade de expressão, pensamento e informação. Nesse contexto, este evento se torna gravoso para o nosso Estado Democrático, na medida que influencia o comportamento, as escolhas políticas, a conduta social e a solidez da (...) própria democracia. Diante do exposto, o objetivo do presente trabalho é refletir como as fake news interferem no Estado Democrático de Direito no Brasil e o deformam. Trata-se de uma revisão bibliográfica, documental e qualitativa. Propõe-se, por meio desse estudo, explicitar o que é esse fenômeno tão complexo das fake news e compreender as diversas formas de como ele pode afetar nosso sistema democrático, baseando-se nas ideias discursivas de Habermas.

A presente pesquisa tem como escopo analisar como as denominadas “razões de segurança” enquanto justificadoras de medidas excepcionais e a existência de uma peste são visualizadas por Giorgio Agamben enquanto paradigmas de governo. O objetivo é demonstrar como esses dois fatores, com a pandemia do coronavírus, se uniram e se transformaram no que o filósofo italiano denomina biossegurança. Para tanto, tratando-se de pesquisa essencialmente bibliográfica, de abordagem qualitativa, serão exploradas obras de Agamben sobre seu método, textos anteriores ao COVID-19 e (...) seus alertas acerca dos dispositivos de controle adotados no combate ao vírus. A partir disso, conclui-se pela importância da tarefa do filósofo em lançar constantemente seu olhar crítico sobre os fenômenos atuais, momentos de seu tempo e história, enquanto esta ainda está em curso.

O presente trabalho realiza uma exposição do pensamento de Robert Alexy no que concerne às relações entre direito e moral, que pode ser entendido como uma tentativa de superação da antiga querela entre juspositivismo e jusnaturalismo. O autor desenvolve, então, um sistemaque permite apreciar as normas jurídicas de acordo com sua qualidade moral, privando de juridicidade aquelas consideradas demasiadamente injustas e corrigindo aquelas consideradassanáveis.

Este escrito contém a crítica de noções tradicionais de subjetividade realizada pelo assim chamado Segundo Wittgenstein, cujo pensamento se expressa principalmente nas Investigações Filosóficas. Como o próprio Wittgenstein recomenda, as passagens de seu segundo pensamento serão confrontadas às suas primeiras formulações sobre o “sujeito”, que tinham relação íntima com a noção de sujeito em Schopenhauer. Após abordarmos brevemente a concepção de sujeito no Tractatus, apresentaremos três aspectos da crítica wittgensteiniana da subjetividade a partir de suas Investigações. Após isso, comentaremos duas (...) tentativas de se extrair uma formulação positiva da subjetividade em Wittgenstein, realizadas por Chantal Bax e Søren Overgaard. Além de expor o aspecto negativo, ou crítico, das formulações de Wittgenstein sobre a subjetividade, pretendemos responder se o sujeito e a subjetividade, para o Segundo Wittgenstein, podem ser conhecidos, e se é possível extrair uma formulação positiva da subjetividade dos escritos wittgensteinianos.

Despite the various perceptual-motor deficits documented in strabismus, there is a paucity of studies evaluating visual illusions in patients with strabismus. The aim of this study was to examine how the illusionary perception occurs in children/adolescents with strabismus with referral for surgery to correct ocular deviations. A controlled cross-sectional study was carried out in which 45 participants with strabismus and 62 healthy volunteers aged 10–15 years were evaluated. The behavioral response to three geometric illusions [Vertical-Horizontal illusion, Müller-Lyer illusion and Ponzo (...) illusion] and respective neutral stimuli regarding the estimation of image size and response time were measured using the Method of Adjustment. To analyze the influence of secondary factors: type of ocular deviation ; amount of eye deviation; presence of amblyopia and stereopsis, a one-way ANOVA was performed. Among the tested illusions, children with strabismus showed greater susceptibility and response time to Ponzo’s illusory images. Children with strabismus and preserved stereopsis, on the other hand, showed similar susceptibility and response time to control group patients to the Ponzo illusion. Patients with amblyopia showed overcorrection in the estimate of non-illusory Ponzo images. Children with horizontal ocular deviation associated with vertical deviation showed higher susceptibility to vertical adjustment images for the Müller-Lyer illusion. Individuals with strabismus tended to overcorrect the length of the straight-line segment adjusted for non-illusory images when testing non-illusory images in the Müller-Lyer test, as well as for the neutral images in the Vertical-Horizontal test. The findings indicated impairment in the perception of geometric illusions and neutral figures, especially for the Ponzo illusion test by children with strabismus. As the behavioral response to illusory images may indirectly reflect the visual and morphofunctional alterations present in these individuals, we suggest that the investigation of visual illusory perception can be used as a new research strategy in the field of investigating the visual function in strabismus.

BackgroundFor a long time, in sports, researchers have tried to understand an expert by comparing them with novices, raising the doubts if the visual search characteristics distinguish experts from novices. Therefore, the aim of the present study was to review and conduct a meta-analysis to evaluate the differences in visual search behavior between experts and novices in team sports athletes.MethodsThis systematic review with meta-analysis followed the PRISMA 2020 and Cochrane's guidelines. Healthy team athletes were included, which engaged in regular practice, (...) from any sex or competitive level, specifically classified a priori as expert or novice in the original research. We considered only research published in peer-reviewed journals, with no limitations regarding date or language. It was considered healthy team sport athletes engaged in regular practice. The scenarios could be in situ or film-based. The databases of EBSCO, PubMed, Scopus, SPORTDiscus, and Web of Science were used to perform the searches. The risk of bias was calculated through the RoBANS tool.ResultsFrom a total of 6,257 records, of which 985 were duplicates, titles and abstracts of 5,272 were screened, and 45 required full-text analysis. Of those, 23 were excluded due to not fulfilling the eligibility criteria regarding participants. In the end, 22 studies were selected, however, as two studies were part of the same trial and were analyzed conjointly.DiscussionExperts showed to be older and with more years of practice. The ability to distinguish experts from novices was not so clear regarding the variables analyzed. This could be due to the strategies chosen in each study, which were specific to each scenario, and when grouping all together, it was lost information within non-representative averages. The distinction between experts and novices was not clear, showing a lot of heterogeneity in the included studies. The expert classification itself may have been the conditioning aspect for these results, retaining the doubt and the need for more studies in the field.Systematic review registrationThe protocol was pre-registered in OSF.

O artigo apresenta uma visão de conjunto do pensamento de Lima Vaz, a partir de seu método original, caracterizado por seu cunho rememorativo, dialético e sistemático. Ele é aplicado particularmente na Antropologia Filosófica e na Ética, sintetizando a categoria de história com a de transcendência, superando assim a crise do pensamento moderno à luz da práxis ética.

Este artigo tem como objetivo fundamental analisar a categoria de reconhecimento e a possível formação de uma comunidade ética. Para isso, analisaremos os principais textos que lidam com o tema do autor contemporâneo Henrique Cláudio de Lima Vaz. O artigo será dividido dialeticamente em três partes. A primeira parte evidenciará o problema da formação de uma comunidade ética como a questão central do nosso tempo. A segunda parte abordará as categorias de intersubjetividade e de reconhecimento como dimensões antropológicas (...) do ser humano. Por fim, na terceira parte, trataremos da questão do reconhecimento e do consenso no plano do agir ético e da vida ética. (shrink)

O presente artigo visa demonstrar a possibilidade de uma justificação e fundamentação racionais da ética, bem assim o seu sentido, segundo o pensamento do filósofo Henrique Cláudio de Lima Vaz. Para tanto, será realizado um exame da fenomenologia do ethos, como objeto da ciência Ética; em seguida, será abordada a questão do sentido de uma justificação e fundamentação racionais da ética, na realidade contemporânea e, finalmente, será apresentada a proposta de Lima Vaz, a partir de dois caminhos (...) convergentes e que culminam apontando a Antropologia Filosófica e a Metafísica como base de tal justificação e fundamentação racional, cuja universalidade decorre do fato mesmo de ser, a Ética, fundamentada na razão filosófica, igualmente universal.

O artigo trata da primeira da fase, bem mais breve, do pensamento filosófico de Lima Vaz, reconhecido como um dos principais filósofos de sua geração no Brasil. Depois de fornecer algumas indicações sobre sua formação intelectual, detém-se na sua reflexão sobre as condições de reconciliação entre a mensagem cristã e o pensamento moderno através de seus artigos sobre “consciência histórica”, visando resgatar o verdadeiro sentido da modernidade. Analisa também a aplicação feita por ele dessas ideias à solução dos graves (...) problemas da sociedade brasileira então em debate, bem como a repercussão pública de sua proposta num momento decisivo da história nacional. Discute em seguida se ele com isso se mostra então favorável a um pensamento cristão alternativo à metafísica tradicional, concluindo por uma provável negativa. (shrink)

O artigo visa identificar traços da fenomenologia de Max Scheler na obra de Henrique Cláudio de Lima Vaz. Pretende-se aprofundar a compreensão do pensamento deste filósofo brasileiro ainda pouco estudado através da aproximação de outras fontes filosóficas implícitas em sua sua escritura ética. No primeiro passo, trata-se de investigar a influência do personalismo moral de Scheler sobre a questão ética em Lima Vaz. No segundo passo, intenciona-se propugnar o ineditismo da Ética filosófica em relação ao pensamento scheleriano (...) graças ao sistema ético-filosófico do autor que faz com que seu pensamento possa ser situado numa esfera mais elaborada do saber filosófico.

Why is gauge symmetry so important in modern physics, given that one must eliminate it when interpreting what the theory represents? In this paper we discuss the sense in which gauge symmetry can be fruitfully applied to constrain the space of possible dynamical models in such a way that forces and charges are appropriately coupled. We review the most well-known application of this kind, known as the 'gauge argument' or 'gauge principle', discuss its difficulties, and then reconstruct the gauge argument (...) as a valid theorem in quantum theory. We then present what we take to be a better and more general gauge argument, based on Noether's second theorem in classical Lagrangian field theory, and argue that this provides a more appropriate framework for understanding how gauge symmetry helps to constrain the dynamics of physical theories.

In this paper, we propose Kripke-style models for the logics of evidence and truth LETJ and LETF. These logics extend, respectively, Nelson’s logic N4 and the logic of first-degree entailment with a classicality operator ∘ that recovers classical logic for formulas in its scope. According to the intended interpretation here proposed, these models represent a database that receives information as time passes, and such information can be positive, negative, non-reliable, or reliable, while a formula ∘A means that the information about (...) A, either positive or negative, is reliable. This proposal is in line with the interpretation of N4 and FDE as information-based logics, but adds to the four scenarios expressed by them two new scenarios: reliable information for the truth and for the falsity of a given proposition.

The eliminative view of gauge degrees of freedom—the view that they arise solely from descriptive redundancy and are therefore eliminable from the theory—is a lively topic of debate in the philosophy of physics. Recent work attempts to leverage properties of the QCD $$\theta _{\text {YM}}$$ θ YM -term to provide a novel argument against the eliminative view. The argument is based on the claim that the QCD $$\theta _{\text {YM}}$$ θ YM -term changes under “large” gauge transformations. Here we review (...) geometrical propositions about fiber bundles that unequivocally falsify these claims: the $$\theta _{\text {YM}}$$ θ YM -term encodes topological features of the fiber bundle used to represent gauge degrees of freedom, but it is fully gauge-invariant. Nonetheless, within the essentially classical viewpoint pursued here, the physical role of the $$\theta _{\text {YM}}$$ θ YM -term shows the physical importance of bundle topology (or superpositions thereof) and thus counts against (a naive) eliminativism.

This text represents our first attempting to offer a Metaphysic model to interpret the late modernity (which emerges in the middle of the 18th century and goes along until the end of the IIWW) through the concept of Teleontology. Thus, Teleontology means the procedure of the spirit of the late modern age to shift its paradigms from ontology (an investigation about the being as being, in which existence means an attribute) to teleology, in which essence must be conquered and revealed (...) in the final of a progressive process. Instead of Being, Man became the main object of this investigation; the question of the being as being has given way as to an enlightened concept of being-man (never reached) as also to the task to achieve this in order to satisfy what reason designed to human species. However, as this project of achieving the concept of Being-Man advanced, its true nature became clear: a unilateral and arbitrary colonial expansion, which forced everyone to follow Teleontological paradigms. Teleontology can demonstrate that Greek-Christian metaphysics means a particular element (never universal) submitted to a specific culture and, in this case, expresses the structure of Eurocentric thought that became global by way of the expanding of capitalism/colonialism. Specifically, in this text, we propose to investigate: 1 - what is Teleontology; 2 - what are its objects; 3 - what are its origins. (shrink)

Not all symmetries are on a par. For instance, within Newtonian mechanics, we seem to have a good grasp on the empirical significance of boosts, by applying it to subsystems. This is exemplified by the thought experiment known as Galileo’s ship: the inertial state of motion of a ship is immaterial to how events unfold in the cabin, but is registered in the values of relational quantities such as the distance and velocity of the ship relative to the shore. But (...) the significance of gauge symmetries seems less clear. For example, can gauge transformations in Yang-Mills theory—taken as mere descriptive redundancy—exhibit a similar relational empirical significance as the boosts of Galileo’s ship? This question has been debated in the last fifteen years in philosophy of physics. I will argue that the answer is ‘yes’, but only for a finite subset of gauge transformations, and under special conditions. Under those conditions, we can mathematically identify empirical significance with a failure of supervenience: the state of the Universe is not uniquely determined by the intrinsic state of its isolated subsystems. Empirical significance is therefore encoded in those relations between subsystems that stand apart from their intrinsic states. (shrink)

Local gauge theories are in a complicated relationship with boundaries. Whereas fixing the gauge can often shave off unwanted redundancies, the coupling of different bounded regions requires the use of gauge-variant elements. Therefore, coupling is inimical to gauge-fixing, as usually understood. This resistance to gauge-fixing has led some to declare the coupling of subsystems to be the \textit{raison d'\^etre} of gauge \cite{RovelliGauge2013}. Indeed, while gauge-fixing is entirely unproblematic for a single region without boundary, it introduces arbitrary boundary conditions on the (...) gauge degrees of freedom themselves---these conditions lack a physical interpretation when they are not functionals of the original fields. Such arbitrary boundary choices creep into the calculation of charges through Noether's second theorem, muddling the assignment of physical charges to local gauge symmetries. The confusion brewn by gauge at boundaries is well-known, and must be contended with both conceptually and technically. It may seem natural to replace the arbitrary boundary choice with new degrees of freedom, for using such a device we resolve some of these confusions while leaving no gauge-dependence on the computation of Noether charges \cite{DonnellyFreidel}. But, concretely, such boundary degrees of freedom are rather arbitrary---they have no relation to the original field-content of the field theory. How should we conceive of them? Here I will explicate the problems mentioned above and illustrate a possible resolution: in a recent series of papers \cite{GomesRiello2016, GomesRiello2018, GomesHopfRiello} the notion of a connection-form was put forward and implemented in the field-space of gauge theories. Using this tool, a modified version of symplectic geometry---here called `horizontal'---is possible. Independently of boundary conditions, this formalism bestows to each region a physically salient, relational notion of charge: the horizontal Noether charge. Meanwhile, as required, the connection-form mediates an irenic composition of regions, one compatible with the attribution of horizontal Noether charges to each region. Thes aims of this paper are to highlight the boundary issues in the treatment of gauge, and to discuss how gauge theory may be conceptually clarified in light of a resolution to these issues.

A partir de um diálogo com a modernidade de Henrique Cláudio de Lima Vaz, considerado um dos maiores filósofos brasileiros, a autora Cláudia Maria Rocha de Oliveira propõe nesta obra duas questões fundamentais: o problema do sentido da existência e a pergunta a respeito da orientação ética para as ações.

After a brief introduction to issues that plague the realization of a theory of quantum gravity, I suggest that the main one concerns defining superpositions of causal structures. This leads me to a distinction between time and space, to a further degree than that present in the canonical approach to general relativity. With this distinction, one can make sense of superpositions as interference between alternative paths in the relational configuration space of the entire Universe. But the full use of relationalism (...) brings us to a timeless picture of Nature, as it does in the canonical approach. After a discussion of Parmenides and the Eleatics' rejection of time, I show that there is middle ground between their view of absolute timelessness and a view of physics taking place in timeless configuration space. In this middle ground, even though change does not fundamentally exist, the illusion of change can be recovered in a way not permitted by Parmenides. It is recovered through a particular density distribution over configuration space which gives rise to 'records'. Incidentally, this distribution seems to have the potential to dissolve further aspects of the measurement problem that can still be argued to haunt the application of decoherence to Many-Worlds quantum mechanics. I end with a discussion indicating that the conflict between the conclusions of this paper and our view of the continuity of the self may still intuitively bother us. Nonetheless, those conclusions should be no more challenging to our intuition than Derek Parfit's thought experiments on the subject. (shrink)

Since communication and expression are central aspects of music performance it is important to develop a systematic pedagogy of teaching children and teenagers expressiveness. Although research has been growing in this area a comprehensive literature review that unifies the different approaches to teaching young musicians expressiveness has been lacking. Therefore, the aim of this article is to provide an overview of literature related to teaching and learning of expressiveness from music psychology and music education research in order to build a (...) new theoretical framework for teaching and learning expressive music performance in instrumental music lessons with children and teenagers. The article will start with a brief discussion of interpretation and expression in music performance, before providing an overview of studies that investigated teaching and learning of performance expression in instrumental music education with adults and children. On the foundation of this research a theoretical framework for dialogic teaching and learning of expressive music performance will be proposed and the rationale explained. Dialogic teaching can be useful for scaffolding young musicians’ learning of expressivity as open questions can stimulate thinking about the interpretation and may serve to connect musical ideas to the embodied experience of the learner. A “toolkit” for teaching and learning of expressiveness will be presented for practical application in music lessons. In addition, a theoretical model will be proposed to further our understanding of teaching and learning of expressive music performance as a multifaceted and interactive process that is embedded in the context of tutors’ and learners’ experiences and environment. Finally, implications of this framework and suggestions for future research will be discussed. (shrink)

Through a theoretical examination of the preventive turn in criminal law and justice which has gained momentum in Anglo-American criminal justice systems since the late-twentieth century, The Preventive Turn in Criminal Law demonstrates how recent transformations in criminal law and justiceare intrinsically related to and embedded in the way liberal society and liberal law have been imagined, developed, and conditioned by its social, political, and historical context. Henrique Carvalho identifies a tension between the idea of punishment as an expression (...) of individual justice, andprevention as a manifestation of the need for security and the promotion of welfare. Tracing this tension back to an intrinsic ambivalence within the modern conception of individual liberty, which is both repressed and preserved by liberal conceptions of responsibility and punishment, Carvalhoproves that as long as this ambivalence remains unexamined, liberal law has the potential to both promote and undermine individual justice.Engaging with the dominant contemporary literature on criminal law, prevention, risk, security, and criminalisation, this volume deploys a theoretical perspective developed through a critical analysis of both classical and contemporary works of social and political theory. The book reveals that thepervasiveness of prevention in 21st century criminal justice systems represents not only the consequence of new and unprecedented features of contemporary politics and society, but also the manifestation of essential aspects of the liberal legal and political tradition.

resumo O artigo pretende revisitar a interpretação hegeliana dos Fundamentos do Direito Natural de Fichte, não propriamente seus elementos críticos, presentes na Differenzschrift e no Naturrechtaufsatz, mas antes a possibilidade de uma assimilação positiva. Em primeiro lugar, oferecemos uma interpretação da passagem entre os §3 e §4 da obra de Fichte, entre a discussão da Aufforderung e a dedução do reconhecimento jurídico, que procura articulála como interface entre educação e direito. Na segunda parte, procuramos revelar o pano de fundo “histórico-espiritual” (...) que permite considerar, no jovem Hegel, um embate entre formas inclusivas e excludentes de intersubjetividade. Na terceira parte, o objetivo é considerar a relação entre a eticidade, enquanto Einssein do universal e do singular, o direito e a educação. Finalmente, pretende-se mostrar que a assimilação positiva de Fichte por Hegel pode ser visualizada na articulação entre formas excludente e participativa de intersubjetividade no conceito de eticidade natural do System der Sittlichkeit, a qual sugere uma mediação entre amor e direito oferecida pela formação. palavras-chave direito; eticidade; reconhecimento; formação; educação.
