This article explores the social representation of Information Technology and Network Society from Barthes' semiology, using his ideas about myth creation and the connotation of ideological discourses through naturalization. Supplemented with some concepts from Peirce and Santaella, we try to identify and understand these mystification mechanisms and how they affect the creation of an information order; in this case, a digital order. We conclude that we are before an evangelizing discursive alignment based on mythical elements arisen from our aversion to (...) uncertainty, the energy-saving principle, and an engineering discourse guided by the urgency of profit and power. We highlight the presence of a reckless narrative that permanently repeats the urgent need for information technology and digitalization without considering side effects or costs. (shrink)

Public decisions concerning large projects with detrimental environmental or heritage impacts involve value conflicts which stem from the diverse interests and variety of ways of evaluating the costs and benefits of such projects. They are also framed by institutionalised procedures and practices which favour certain concerns to the detriment of others. This paper aims to contribute towards a better understanding of how these procedures and practices, namely decision support tools such as the Environmental Impact Assessment (EIA), tend to shape public (...) decision-making processes in particular ways. It draws on a study of the public controversy surrounding the Foz Tua dam in Portugal, with a focus on the values upheld by the different parties in the controversy and their interplay in the production of justifications, specifically the actors’ positions on values and value conflicts and the restrictions posed by institutionalised public decision-making procedures on the expression and consideration of certain values.

O presente artigo apresenta uma análise filosófica do conto _Um discurso sobre o método _escrito por Sérgio Sant’Anna. O objetivo da análise é demonstrar que o conto é construído como um esforço de mímesis da filosofia cartesiana. Parte-se do pressuposto que o texto artístico comporta múltiplas interpretações, principalmente quando construído em diálogo com a filosofia. Do tema em destaque, o cartesianismo defende a ideia de que a subjetividade é um dado radical sem ligação com o entorno material, social e cultural. (...) Todavia, o contista contemporâneo discorda deste isolamento e constrói uma narrativa na qual o ‘eu’ é descoberto através de vários métodos. Com isto amplia-se a compreensão hodierna de que o sujeito não está fechado sobre parâmetros científicos estritos, e sim se abre a inúmeras manifestações fenomênicas. Esta análise literária e filosófica vai amparada nos conceitos analíticos de Gerard Genette em _O discurso da narrativa, _assim como em concepções literárias de Edgar Allan Poe, Júlio Cortázar e Ricardo Piglia além, é claro, de algumas obras de René Descartes. O resultado alcançado é um exercício especulativo que, à primeira vista, parece uma crítica ao puro cartesianismo, mas que, ao contrário, se posiciona como um complemento que reconhece e amplia os caminhos da modernidade para o estudo do ‘eu’. Em acréscimo indicam-se semelhanças entre o conto e a obra de Descartes, o que reforça nossa tese de mímesis e complementariedade entre a obra literária e a filosófica. (shrink)

Culling is used in traditional public health policies to control animal populations. These policies aim primarily to protect human interests but often fail to provide scientific evidence of effectiveness. In this article, we defend the need to move from a strictly anthropocentric approach to disease control towards a One Health ethics, using culling practices as an example. We focus on the recent badger culls in the UK, claiming that, based on data provided by the English Government, these culls may be (...) unjustified, all thing considered. We highlight the relevance of ethical reasoning rooted in One Health for this discussion, and make several suggestions including a moratorium on culling until data are provided to support the effectiveness of culling; to conduct a randomized trial to compare proactive culling with alternative methods; to apply deliberative democratic methods to assess public opinion towards the culls, and to find in Brexit an opportunity for aiming for more effective control measures.

Coletânea de vinte textos, elaborados por professores de várias universidades, que analisam, a partir de diferentes ângulos, questões de teoria e metodologia nos cursos de História. A reflexão para pensar a nossa história, o ensino, a historiografia histórica, da 'história total' à 'história em migalhas', o livro didático de história e a história no fim do milênio são temas discutidos na obra.

O presente artigo debruça-se na crítica de Diderot à Helvétius. Apesar da crítica ser feita pontualmente a cada trecho comentado do livro De l’Homme de Helvétius, consideramos que ela possui um núcleo principal, que é a diferente concepção de materialismo dos autores e suas consequências para o que ambos anseiam para a sociedade. Por isso, investigamos o que há no horizonte do materialismo de Helvétius e de Diderot no que concerne à educação e como, apesar de estarem próximos no ponto (...) de partida, o materialismo, seu norte é diferente. A escolha do tema da educação justifica-se por tratar-se de algo que ultrapassa a teorização filosófica e busca inserção prática na sociedade, mostrando assim não só as consequências práticas das teses materialistas como também o ideal de sociedade proposto por cada autor. Aqui, apontamos para as principais diretrizes sobre a construção de uma educação institucional em De l’Esprit (1754) e De l’Homme (1771), de Helvétius, nas Em Reflexions sur le livre De l’Esprit (1877) e Refutations suivre l’ouvrage intitule De l’Homme (1877)1, e em outras obras de Diderot. 1 As críticas reunidas de Diderot foram publicadas apenas postumamente. Estima-se que a segunda, dedicada à De l’Homme foi redigida em um longo período, que coincide com a redação do Plan d’Université (1775) e Elements de Phisiologie (1875). (shrink)

Competitive sports involve physiological, technical and psychological skills, which influence directly on individuals’ performance. This study aims to investigate the levels of perceived stress and Heart Rate Variability before and after matches with victory and defeat in professional eSports athletes. Our hypothesis was that the winners would have better autonomic and stress responses after match, thus corroborating the literature on neurocardiac connections. Fifty male eSport players were selected players from 10 different Brazilian teams. The experiment was carried out in 2 (...) sessions. Firstly, after signing the informed consent form, 24 h before the game, anthropometric, physical activity levels and time of expertise data were recorded only for sample characterization and the players were familiarized with the perceived stress scale—10 and the HRV measurements. Secondly, players performed the PSS-10 and HRV recording at rest by 10 min 60 and 30 min before the game and 10 min after the end of the game. Overall, concerning PSS-10 our findings show that VG had significant reduced scores in post-game time compared to baseline and pre-game times, while DG had significant increased scores in post-game time compared to BL and pre-game times. Regarding HRV, our results demonstrate that VG had significant increase in RR, SDNN, rMSSD, pNN50 and HF, and significant decrease in LF and LF/HF, while DG had a significant decrease in RR, SDNN, rMSSD and HF, and significant increase in LF and LF/HF. It was observed that VG had better HRV responses as well as lower levels of perceived stress, while DG had worst HRV responses and higher levels of perceived stress. (shrink)

Existe uma reconhecida proximidade entre os materialistas franceses do século XVIII que teria se mostrado tanto em investigações sobre a natureza quanto à moral e organização pública. Porém, as divergências entre eles podem desencadear um entendimento muito diferente sobre como se considera uma sociedade. Por isso é necessário analisar no detalhe tais divergências para determinar seu ponto nevrálgico. O presente artigo dedica-se à investigação das críticas feitas por Diderot à Helvétius, reunidas em Réfutations d’Helvétius. Para tanto, centra-se na distinta concepção (...) da natureza da sensibilidade humana e sua importância para o desenvolvimento humano no que concerne à educação e a moral. (shrink)

O presente artigo aborda a recente decisão do Secretário de Educação do Estado do Paraná de retirar metade da carga-horária das aulas de Artes, Filosofia e Sociologia no Ensino Médio. Ao analisarmos, podemos associar tal medida com a lenta e gradual redução do Ensino Médio a um ensino profissionalizante, e não mais com o desenvolvimento global dos estudantes, afastando-o assim do Ensino Básico.

Physical exercise is seen as the main ally for health promotion, preventing and protecting the organism from several diseases. According to WHO, there is a tendency of constant growth in the elderly population in the coming years. The regular practice of exercises by the elderly becomes relevant to minimize the deleterious effects of the aging process and to increase the fitness index. Recently, the world population started a confrontation against Corona Virus Disease (COVID-19), which is the most significant public health (...) challenge globally. Although social isolation is a reasonable measure in an attempt to stop contamination by COVID-19, this measure has limited the ability of individuals to exercise outdoors or in gyms and health clubs, which increased the risk of developing chronic illnesses related to a sedentary lifestyle. The critical point is that the recent recommendations on exercise prescription to combat the potentially harmful effects of COVID-19 failure to adequately address resistance exercise interventions as home-based exercise strategy. Thus, in this paper, we discussed the physical exercise as medicine if the training status is enough to protect the elderly against COVID-19 infection, about the role of physical activity on immunosuppression. Possible risks for COVID-19 infection, and the old training methods, such as no-load resistance training as possible resistance exercise strategies and high-intensity interval training, as new proposals of home-based exercise interventions, could perform during the current COVID-19 pandemic.

Efforts have been dedicated to the understanding of social-ecological systems, an important focus in ethnobiological studies. In particular, ethnobiological investigations have found evidence and tested hypotheses over the last 30 years on the interactions between human groups and their environments, generating the need to formulate a theory for such systems. In this article, we propose the social-ecological theory of maximization to explain the construction and functioning of these systems over time, encompassing hypotheses and evidence from previous ethnobiological studies. In proposing (...) the theory, we present definitions and two conceptual models, an environmental maximization model and a redundancy generation model. The first model seeks to address biota selection and its use by human populations. The second emphasizes how the system organizes itself from the elements that were incorporated into it. Furthermore, we provide the theoretical scenario of plant selection and use from an evolutionary perspective, which explicitly integrates the phylogenetic relationships of plants and human beings.

BackgroundIn Palliative Care, family and close people are an essential part of provision of care. They assume highly complex tasks for which they are not prepared, with considerable physical, psychological, social and economic impact. Informal Caregivers often falter in the final stage of life and develop distress, enhancing emotional burden and complicated grief. The lack of available and accessible in-person counselling resources is often reported by ICs. Online resources can promote early access to help and support for patient-IC dyads in (...) palliative care. The primary aim of this research is to co-design, develop and test the feasibility of the Help2Care-PAL mHealth app that addresses the needs of ICs of palliative patients cared for at home. This Digital Health Intervention in palliative care will be used for education, symptom management, communication and decision-making, to enhance Quality of Life of patients and ICs, fostering anticipatory grief and the reach and efficiency of services.MethodsThis study will use an iterative co-design process and convergent mixed-methods design, following the MORECare consensus for developing a complex intervention. Construction of the DHI will follow four main phases: a needs assessment ; design and co-production of mHealth materials and interventions to support ICs; the development of a mHealth app; and usability and feasibility of the mHealth app. The Help2Care-PAL platform seeks to build resources from the perspectives and needs of both family dyads and nursing professionals working in the field of community palliative care. User-centeredness will be ensured by the active participation of patient-IC dyads and professionals of the palliative care community.DiscussionThis mixed-method study will offer new insights on needs and expectations of patient-IC dyads and nurses in community palliative care regarding caregiving preparedness and online health resources. Through the implementation of an adaptive digital tool, we aim to improve access to palliative care family support, which is highly linked with the wellbeing of patients and especially new ICs.

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.

Pensar é uma espécie de exercício responsável que não pode ser omitido neste momento que vivenciamos e partilhamos. Por isso, cultivar boas reflexões depende, por um lado, da capacidade técnico-acadêmica de pesquisadoras e pesquisadores e, por outro, da maneira como conduzem o seu horizonte filosófico diante de um quadro de perspectivas e desafios. Assim, a produção filosófica não precisa de milagres para compreender a natureza, como afirmará Espinosa, mas de uma aliança entre liberdade e razão.É neste sentido que o presente (...) número da Aurora contempla o dossiê “Atualidade da Filosofia de Espinosa: Matéria e potência”, organizado pelos professores Ricardo Espinosa Lolas e Eladio Craia.O Fluxo Contínuo, por sua vez, dispõe dos artigos “Fantasised alterity, inaudible voices.

The world of work has been severely affected by the COVID-19 pandemic due to the high instability observed in the labor market, bringing several new challenges for leaders and employees. The present study aims to analyze the role of organizational and job resources in predicting employees’ job insecurity during the first wave of the COVID-19 outbreak, through the mediating role of work engagement. A sample of 207 Portuguese employees participated, of which 64.7% were women. Data was collected using an online (...) survey, including self-report measures of organizational resources, job resources, job insecurity, and work engagement. Data showed that job and organizational resources negatively influenced job insecurity. Moreover, work engagement was a significant mediator of the relation between performance feedback and job insecurity. Findings suggest that investing in job and organizational resources can act as protective factors to minimize feelings of job insecurity. Likewise, leaders should foster work engagement among employees to help them balance the relation between these resources and job insecurity, especially in crisis situations. Overall, this study takes a new, underexplored perspective, theoretically bridging organizational and job resources with job insecurity and work engagement during a time of great uncertainty, such as the COVID-19 pandemic.

Introduction: The teacher-student relationship in medicine determines the bond established with the patient. Objective: This study was designed to compare if first and third year medical students at a university perceived incidents perpetrated by teachers as morally wrong. Materials and methods: A semi-structured survey was used with open and closed items; specifically, participants were asked to relate a morally wrong incident, classified to six categories. Results: 80.7% in the third-year students and 30.4% of the first-year students perceived incidents that involved (...) mostly auxiliary personnel and evaluations. Verbal abuse and unfair assessment were the categories mentioned the most. Discussion: A morally wrong incident is a general concept, differing from other studies that specifically analyze abuse, also evident in this concept. Conclusion: A lack of respect and justice could indicate a lack of moral commitment. (shrink)

Neste artigo apresentamos, de forma concisa e em português, alguns elementos-chave dos principais debates contemporâneos na filosofia da memória. Nosso principal objetivo é tornar essas discussões mais acessíveis aos leitores de língua portuguesa, fornecendo uma atualização importante para esforços anteriores (Sant’Anna & Michaelian, 2019a).

Primeiro, o debate entre causalistas e simulacionistas sobre a (...) teoria da lembrança filosoficamente correta (§2). Segundo, o debate entre continuístas e descontinuístas sobre a relação entre lembrança episódica e certas formas de imaginação (em particular, o pensamento episódico acerca do futuro) (§3).

Iowa Gambling Task (IGT) is one of the most widely used tools to assess economic decision-making. However, the research tradition on aging and the Iowa Gambling Task (IGT) has been mainly focused on the overall performance of older adults in relation to younger or clinical groups, remaining unclear whether older adults are capable of learning along the task. We conducted a meta-analysis to examine older adults’ decision-making on the IGT, to test the effects of aging on reversal learning (45 studies) (...) and to provide normative data on total and block net scores (55 studies). From the accumulated empirical evidence, we found an average total net score of 7.55 (± 25.9). We also observed a significant reversal learning effect along the blocks of the IGT, indicating that older adults inhibit the prepotent response towards immediately attractive options associated with high losses, in favor of initially less attractive options associated with long-run profit. During block 1, decisions of older adults led to a negative gambling net score, reflecting the expected initial pattern of risk-taking. However, the shift towards more safe options occurred between block 2 (small-to-medium effect size) and blocks 3, 4, 5 (medium-to-large effect size). These main findings highlight that older adults are able to move from the initial uncertainty, when the possible outcomes are unknown, to decisions based on risk, when the outcomes are learned and may be used to guide future adaptive decision-making.

We introduce and study a new approach to the theory of abstract algebraic logic (AAL) that explores the use of many-sorted behavioral logic in the role traditionally played by unsorted equational logic. Our aim is to extend the range of applicability of AAL toward providing a meaningful algebraic counterpart also to logics with a many-sorted language, and possibly including non-truth-functional connectives. The proposed behavioral approach covers logics which are not algebraizable according to the standard approach, while also bringing a new (...) algebraic perspective to logics which are algebraizable using the standard tools of AAL. Furthermore, we pave the way toward a robust behavioral theory of AAL, namely by providing a behavioral version of the Leibniz operator which allows us to generalize the traditional Leibniz hierarchy, as well as several well-known characterization results. A number of meaningful examples will be used to illustrate the novelties and advantages of the approach. (shrink)

Nowadays and worldwide, the attention is focused on coronavirus disease, and its consequences on mental health are yet to be fully understood. It is important to capture differences in anxiety levels among populations, groups, and the gender-related variation. Therefore, the present study had two main purposes: to characterize the levels of state anxiety and trait anxiety by examining gender-related, sleep-related, and physical activity-related variations in a nonrepresentative sample of the Portuguese population during the first weeks of lockdown; and to explore (...) the possible relationship between trait anxiety and state anxiety and the possible role of gender as a moderator. This cross-sectional study comprised 1,332 Portuguese adults recruited online during COVID-19 outbreak measures. Participants answered to sociodemographic data and the Portuguese version of the State-Trait Anxiety Inventory. Gender differences were found in both state anxiety and trait anxiety with females presenting higher values. People reporting doing more physical activity than usual during COVID-19 lockdown presented lower levels of state anxiety. People reporting more satisfaction with the quality of sleep presented lower levels of both state anxiety and trait anxiety. Variation associated with the physical activity level was significantly different among groups in both state anxiety and trait anxiety. When analyzing in more detail separating the levels of physical activity, participants performing moderate and high physical activity showed lower values of state and trait anxiety compared to participants with low physical activity. Participants performing high physical activity also showed lower values of state anxiety compared to participants performing moderate physical activity. Higher levels of trait anxiety were related to higher levels of state anxiety, but this association was not moderated by gender. Interventions aiming to support people psychologically during this outbreak should consider anxiety as well as gender and possible behavioral changes in sleep and physical activity, for example. Health professionals should not only consider the anxiety related to the situation we are living but also address trait anxiety to help overcome COVID-19 psychological consequences. (shrink)

O presente ensaio pretende analisar o Cooperativismo Educacional no estado de São Paulo, em suas formas institucionais, agora voltados para a organização escolar a partir de 1980.

O texto tematiza em que sentido a experiência de Alfabetização filosófica se inspira e ao mesmo tempo se diferencia do curso de Alfabetização oferecido por Paulo Freire em (...) Angicos em 1963. Inspirado na curiosidade e no compromisso de Paulo Freire com os esfarrapados do mundo, o conceito “alfabetização filosófica” propõe uma formação experiencial sustentada nas seguintes disposições: escutar atentamente o mundo humano e não humano que nos rodeia; pensar juntos com cuidado e calma; relacionarmo-nos cooperativa e não competitivamente com as ideias das outras pessoas; perguntarmo-nos, colocando em questão, nossa vida e a maneira como nos relacionamos com ela, num tempo especial, singular, suspendido; conversar como iguais na busca de enfrentar as exigências de nossa comunidade; inventar novas formas de estar com outras e outros. O texto apresenta como essas disposições foram pensadas e praticadas durante a alfabetização filosófica em Pau dos Ferros, RN, através de cinco princípios (perguntar; escutar; tempo de infância; igualdade; pensar juntos) e lança algumas perguntas sobre possíveis desdobramentos da alfabetização filosófica no campo de formação de professores.

The imperative to practice hospitality constitutes a mark of Western civilization. Already in Homer’s Odyssey, the hero Ulysses punishes Polyphemus for not having respected the obligation of hospitality towards him and his companions. In fact, hospitality has been a constitutive element of the West, marked by linguistic, cultural, and religious differences, in a world whose borders are supposed to be well defined. In his discussion of hospitality, Derrida shows how Socrates, in Plato’s dialogue The Apology of Socrates, places himself in (...) the position of a foreigner. In fact, Socrates presents himself as foreigner, that is, someone who is alien to the language and procedures of the court that is judging him. According to Derrida, he shows, in this way, the extent to which the foreigner is forced to ask for hospitality in a language he does not know. The court reduces Socrates to the other, the different. Moreover, the court forces him to deny his difference, his own identity, asking him to adapt himself to a system that he does not control. The paradox arises when Socrates, who regrets being regarded as a foreigner, asks the court to treat him at least as a foreigner. He feels so outraged that he asks to be granted at least the rights of a non-national. In doing so, Socrates shows how recognizing the rights of the foreigner generates hospitality but, at the same time, also limits it. Whenever a human being is recognized as human being, he or she will necessarily be seen as another, as someone different. This person will have to adapt him or herself to a system, culture or world that will define him or her as a foreigner. In short, in the phenomena that we tend to see as hospitality there is always a certain hostility. In a world of ongoing migratory crises, and in the context of a return to nationalisms of exclusion combined with populisms of prejudice and aversion to those who are different, it becomes imperative to rethink the ethics and politics of hospitality. In this context, Derrida’s distinction between conditioned and unconditioned hospitality can be useful. (shrink)

Climate change exposes ecological and socio-economic systems to risks. The identified disparities in knowledge about the social climate system are at the root of the difficulties in perceiving and understanding the diversity of risks related to climate change. The still huge gap between what science and technological innovation can contribute to mitigation and what is unmanageable by humans inevitably requires a continuous process of adaptation. This work is part of the research associated with the European project (under the ERA4CS) 'Citizen (...) Sensing - Urban climate resilience through participatory risk management systems', which proposes to develop a Participatory Climate Risk Management System, a two-way communication system where is part of a participatory risk management system, contributing to adaptive governance. These objectives will be achieved through the creation of a platform that will incorporate information gathered from four pilot studies: Norrköping (Sweden), Porto (Portugal), Rotterdam (The Netherlands) and Trondheim (Norway). Ultimately, the aim is to draw conclusions on how this application can contribute to improving citizens' literacy to cope with climate change adaptation and to raise awareness of this problem, as the involvement of citizens and stakeholders will only be improved if the perception of the risk of climate change is substantially increased. Awareness campaigns about the potential risks associated with extreme events are of great importance. Citizens tend to view climate change as a global phenomenon, ignoring and avoiding taking action until it is directly and seriously affected. (shrink)

ABSTRACT This article aims to defend the dialogical nature of the landscape. Working in between the borders of the Bakhtinian philosophy of language and cultural studies on landscape, we defend that landscape study should not be studied without considering the cultural forms of communication in the different domains of social organization– the speech genres; that landscape is a semiotic encounter with a concrete otherness; that the interpreter who emerges when an area enters a relationship of representation is necessarily characterized as (...) a chronotope; that every landscape is a chronotopic representation; that cultural geography recognizes that the semiotic aspects of the landscape are as material as its morphology. We start from the hypothesis that landscape is a chronotopic representation that is always made possible by means of some speech genre, because it is always a communicative process, and an encounter with another in a situation of socially organized interrelation – it is concrete dialogue. To find the deeper meaning of a landscape, one must recognize and understand its material, historical, geographical, and dialogic nature. RESUMO O artigo objetiva defender a índole dialógica da paisagem. Trabalhando na fronteira entre a filosofia bakhtiniana da linguagem e os estudos culturais da paisagem, defendemos que a paisagem não seja estudada sem considerar as formas culturais de comunicação nos diferentes domínios da organização social – os gêneros discursivos; que toda paisagem é encontro semiótico com uma alteridade concreta; que o intérprete que emerge quando uma área entra em relação de representação é necessariamente caracterizado por um cronotopo; que toda paisagem é representação cronotópica; que a geografia cultural reconheça que os aspectos semióticos da paisagem são tão materiais quanto sua morfologia. Partimos da hipótese de que a paisagem é uma representação cronotópica que sempre se realiza através de algum gênero discursivo, pois sempre é um processo comunicativo e de encontro com o outro em uma situação de inter-relação socialmente organizada – é diálogo concreto. Para adentrar à profundeza de seus sentidos, precisa-se reconhecer e compreender sua índole material, histórica, geográfica e dialógica. (shrink)

It is well-known that da Costa's C-systems of paraconsistent logic do not admit a Blok-Pigozzi algebraization. Still, an algebraic flavored semantics for them has been proposed in the literature, namely using the class of so-called da Costa algebras. However, the precise connection between these semantic structures and the C-systems was never established at the light of the theory of algebraizable logics. In this paper we propose to study the C-systems from an algebraic point of view, and to fill in this (...) gap by using the tools and techniques of the newly developed behavioral approach to abstract algebraic logic. As a by-product of the approach, we also rediscover the bivaluation semantics of the logics. (shrink)

Normative systems have been advocated as an effective tool to regulate interaction in multi-agent systems. The use of deontic operators and the ability to represent defeasible information are known to be two fundamental ingredients to represent and reason about normative systems. In this paper, after introducing a framework that combines standard deontic logic and non-monotonic logic programming, deontic logic programs (DLP), we tackle the fundamental problem of equivalence between normative systems using a deontic extension of David Pearce’s Equilibrium Logic and (...) its monotonic basis, the logic of Here-and-There. We also show how deontic logic programs can be used to represent and reason about normative systems, and establish a strong connection with input-output logic. (shrink)

This study explored the associations between physical activity anxiety levels, and the perception of satisfaction of basic psychological needs, during Coronavirus Disease 2019 lockdown. Thus, 1,404 participants ranging from 18 to 89 years old completed a questionnaire in the period between 1st and 15th April 2021. The survey included sociodemographic data and the following validated instruments: the International Physical Activity Questionnaire, the Basic Need General Satisfaction Scale and the State-Trait Anxiety Inventory. The Kruskal-Wallis test was performed to examine variation in (...) anxiety levels and BPN satisfaction according to PA category. Spearman’s Rho correlations coefficients were used to determine the association between anxiety levels and psychological needs. Individuals presenting a higher level of PA revealed lower levels of anxiety-state. Differences between elements from different levels of PA were found for the autonomy, competence, and relatedness psychological needs, suggesting that those who feel their BPN as more satisfied have higher levels of PA. The study found statistically significant correlations between anxiety-state and the satisfaction of the needs for autonomy, competence, and relatedness. These findings support the importance that PA has in the anxiety levels during social isolation, emphasizing the importance of multidisciplinary teams in an individual-based approach. (shrink)

We define and study abstract valuation semantics for logics, an algebraically well-behaved version of valuation semantics. Then, in the context of the behavioral approach to the algebraization of logics, we show, by means of meaningful bridge theorems and application examples, that abstract valuations are suited to play a role similar to the one played by logical matrices in the traditional approach to algebraization.

No período pandêmico ocasionado pelo Novo Coronavírus, surgiram muitas Fake News nas redes sociais digitais, gerando desinformação e prejudicando a Administração Pública na contenção de novos casos. Demonstra-se por meio da análise da publicização dos boletins epidemiológicos da Covid-19, disseminados nas redes sociais do Governo do Estado de Alagoas, a importância da transparência nas informações de interesse público. Essas redes, principais meios de comunicação e informação da sociedade, têm alto poder de disseminação informacional, cujo potencial “viral”, proporcionado pela instantaneidade e (...) interatividade, alcança uma infinidade de públicos. Como espaços férteis para o surgimento de Fake News e desinformação, podem gerar crises de confiabilidade e veracidade quanto às informações divulgadas pelo Governo, bem como não estimular o alagoano ao exercício da cidadania, nem agregar valor a essa sociedade. A partir do exposto, constata-se que a informação, nesse ambiente digital, deve ser tratada de forma crível, clara e responsável, com vistas a gerar maior confiabilidade, interação e acesso à informação de interesse social, bem como contribuir para a redução da circulação de Fake News e Desinformação. Adotou-se as pesquisas documental e qualitativa com uma abordagem exploratória, realizando-se a coleta de dados nas redes sociais oficiais do governo alagoano: Facebook, Instagram e Twitter. (shrink)
