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)

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)

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)

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)

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)

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)

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.

O presente trabalho visa apresentar a recepção que Axel Honneth faz da obra de Facticidade e Validade de Jürgen Habermas. Argumenta-se que, por mais que Honneth não explicite isso em seus escritos posteriores a publicação do livro de Habermas, a obra exerce influência determinante em suas produções que culminam em O direito da liberdade. Assim, apresenta-se tanto a primeira crítica a de Honneth a Habermas, quanto os momentos posteriores de diálogo com a Facticidade e Validade. Ao final, busca-se identificar as (...) consequências da recepção e dos afastamentos de Honneth em relação a esse marco teórico e os próprios caminhos que a teoria crítica tomou em relação ao direito, bem como as possibilidades teóricas da perspectiva honnethiana sobre o tema.

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.

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.

This book develops a philosophical analysis of economic reality and economic science from an Aristotelian point of view. It is the result of many years of thinking and philosophical study about these topics. It differs from other philosophy of economics books as it also deals with economic reality (not only the science) and approaches its subject from an Aristotelian perspective. It differs from other Aristotelian studies about economics as it covers the whole of philosophy of the economy. This book argues (...) why Aristotle's thinking guarantees an appropriate interdisciplinary synthesis. (shrink)

In this chapter, Ricardo Silvestre and Alan Herbert offer a reconstruction of the Gītā’s concept of God with a focus on the relationship between God and the world. They try to explain the claim that the Gītā is panentheistic. This is done with the help of some key notions of contemporary metaphysics (such as ontological dependence and fundamentality) along with the Indic notion of prakṛti, considered as a metaphysical primitive denoting the intimate relationship that exists between matter and conscious (...) living beings on the one hand, and God on the other.

The use of new paradigms of false belief tasks allowed to reduce the age of children who pass the test from the previous 4 years in the standard version to only 15 months or even a striking 6 months in the nonverbal modification. These results are often taken as evidence that infants already possess an—at least implicit—theory of mind. We criticize this inferential leap on the grounds that inferring a ToM from the predictive success on a false belief task requires (...) to assume as premise that a belief reasoning is a necessary condition for correct action prediction. It is argued that the FBT does not satisfactorily constrain the predictive means, leaving room for the use of belief-independent inferences. These heuristics, when applied to the FBT, can achieve the same predictive success of a belief-based inference because information provided by the test stimulus allows the recognition of particular situations that can be subsumed by their ‘laws’. Instead of solving this issue by designing a single experimentum crucis that would render unfeasible the use of non-representational inferences, we suggest the application of a set of tests in which, although individually they can support inferences dissociated from a ToM, only an inference that makes use of false beliefs is able to correctly predict all the outcomes.

In this essay, I focus on Lugones’s relatively lesser explored notion of playfulness. I weigh in on the debate about whether playfulness is necessary for what Lugones calls “world-traveling,” which enables one to recognize another person as a full subject. I argue that although the attribute of playfulness may not be necessary for world-traveling, it is necessary for collaborative world-making––creating a new, shared world that is opened through the activity of play.

Is it possible to combine different logics into a coherent system with the goal of applying it to specific problems so that it sheds some light on foundational aspects of those logics? These are two of the most basic issues of combining logics. Paranormal modal logic is a combination of paraconsistent logic and modal logic. In this paper, I propose two further combinatory developments, focusing on each one of these two issues. On the foundational side, I combine paranormal modal logic (...) with normal modal logic, resulting into a paraconsistent and paracomplete multimodal logic dealing with the notions of plausibility and certainty. On the application side, I combine this logic with Reiter’s default logic, resulting into an inductive and consequently nonmonotonic paraconsistent and paracomplete logic able to represent some key inductive principles.

Any plausibly just market exchange must balance two conflicting moral considerations: non-worseness (Wertheimer, 1999) and euvoluntariness (true voluntariness; Munger, 2011). We propose an analytical theory of just market exchange that partly resolves this conflict.

Os processos de integração regional em curso hoje na América Latina têm sido marcados por uma lógica territorial que tem concebido grandes áreas do espaço geográfico latino-americano como “vazios demográficos” ou “terras disponíveis”. Essa forma de conceber o espaço geográfico latino-americano remonta ao legado colonial que atravessa a formação sócio-espacial da região e a própria posição que o continente americano ocupou no processo de formação do sistema-mundo moderno-colonial, a partir de 1492. Este artigo tem por objetivo problematizar os processos de (...) integração física em curso atualmente no continente, especificamente a Iniciativa para Integração da Infra-estrutura Regional Sul-Americana (IIRSA), buscando evidenciar a reprodução da lógica da colonialidade do poder e do saber constituintes de seu modelo de desenvolvimento regional.

O presente artigo trata da geografia da violência urbana na cidade do Rio de Janeiro. Mostra como a ação do Estado está permeada por ignorâncias acerca das lógicas de experiências espaciais com que se organizam e operam as classes populares trabalhadoras do Rio de Janeiro. O objetivo é estimular uma discussão que impulsione as análises para além dos discursos estigmatizadores com relação à população favelada. A metodologia adotada assemelha-se às sinuosidades dos becos e vielas, visto que optamos em nos entranhar (...) empiricamente na concretude do espaço favelado e, também, nas re-leituras das narrativas marginalizadas, dos compositores que há décadas oferecem pistas para que possamos esboçar um mapeamento das lógicas de sociabilidades e das experiências de espaço dessa população. Assim, podemos afirmar – ainda que hipoteticamente – que os mecanismos convencionais de análises e os instrumentos metodológicos fundamentados no distanciamento dos seus “objetos” são insuficientes para uma mínima compreensão do que se passa nos cotidianos de opressão e resistências das classes populares. O máximo que se tem alcançado historicamente, tanto com as pesquisas quantitativas acerca do tema quanto com os apelos midiáticos, é a forte influência na construção de discursos universalistas que naturalizam a criminalização dos citadinos mais pobres e as suas lógicas de integração-sobrevivência nas cidades.

El artículo versa sobre la relación entre epistemes, espacio y poder. Cuestiona la presunción de universalidad tal como es pensada por la tradición hegemónica europea -eurocentrismo- pero rechaza cualquier pretensión de universalidad unidireccional venga de donde venga.

Parte del pensamiento subalterno y valoriza los espacios de conflicto como epistémicamente densos, aportando además que el debate acerca de los territorios quizás sea la mejor expresión de la naturalización de las relaciones sociales y de poder que el territorio comporta, significando, en verdad, cuán profundas son las transformaciones en curso en los días actuales.

We uncover fundamental dimensions of the process through which organizations embed the practice of fraternity through embarking on an organizational journey in the direction of the common good. Building on the latest encyclical of Pope Francis, _Fratelli Tutti_, about fraternal and social friendship, we offer insight into the understanding of what it means to become a fraternal organization and reflect on the key ethical and paradoxical challenges for organizations aiming at collectively contributing to the common good. We add to previous (...) work by characterizing this journey as a process involving unique ethical challenges that emerge from the paradoxes associated with this process and how this might change the nature of the relationships between organizations and others within the organizational landscape.

Mathematics is a critical part of much scientific research. Physics in particular weaves math extensively into its instruction beginning in high school. Despite much research on the learning of both physics and math, the problem of how to effectively include math in physics in a way that reaches most students remains unsolved. In this paper, we suggest that a fundamental issue has received insufficient exploration: the fact that in science, we don’t just use math, we make meaning with it in (...) a different way than mathematicians do. In this reflective essay, we explore math as a language and consider the language of math in physics through the lens of cognitive linguistics. We begin by offering a number of examples that show how the use of math in physics differs from the use of math as typically found in math classes. We then explore basic concepts in cognitive semantics to show how humans make meaning with language in general. The critical elements are the roles of embodied cognition and interpretation in context. Then, we show how a theoretical framework commonly used in physics education research, resources, is coherent with and extends the ideas of cognitive semantics by connecting embodiment to phenomenological primitives and contextual interpretation to the dynamics of meaning-making with conceptual resources, epistemological resources, and affect. We present these ideas with illustrative case studies of students working on physics problems with math and demonstrate the dynamical nature of student reasoning with math in physics. We conclude with some thoughts about the implications for instruction. (shrink)

This collection of new essays by an international group of scholars closely examine the works of Aristotle's Organon. The Organon is the general title given to the collection of Aristotle's logical works: Categories, De Interpretatione, Prior Analytics, Posterior Analytics, Topics and Sophistical Refutations. This extremely influential collection gave Aristotle the reputation of being the founder of logic, and has helped shaped the development of logic for over two millennia. The chapters in this volume cover topics pertaining to each of the (...) six works traditionally included in the Organon as well as its manuscript tradition. In addition, a comprehensive introduction by the editors discusses Aristotle and logic, the composition and order of the Organon, and the authenticity, title, and chronology of the treatises that make up these works New Essays on Aristotle's Organon offers a valuable insight into this collection for students and scholars working on Aristotle, the works of the Organon, or the philosophy of logic more broadly.
