Huge losses and serious threats to ecosystems are common consequences of forest fires. This work describes a forest fire controller based on fuzzy logic and decision-making methods aiming at enhancing forest fire prevention, detection, and fighting systems. In the proposal, the environmental monitoring of several dynamic risk factors is performed with wireless sensor networks and analysed with the proposed fuzzy-based controller. With respect to this, meteorological variables, polluting gases and the oxygen level are measured in real time to estimate the (...) existence of forest fire risks in the short-term and to detect the recent occurrence of fire outbreaks over different forest areas. Besides, the Analytic Hierarchy Process method is used to determine the level of fire spread, and, when necessary, environmental alerts are sent by a Web service and received by a mobile application. For this purpose, integrity, confidentiality, and authenticity of environmental information and alerts are protected with implementations of Lamport’s authentication scheme, Diffie-Lamport signature, and AES-CBC block cipher.

The use of wireless sensor networks and the Internet of things to detect forest fire outbreaks may help to reduce the response time and avoid natural disasters. This work proposes the deployment of WSN to enhance the real-time monitoring of dynamic variables such as polluting gases, temperature or the presence of fire flames by infrared. In addition, the activation of forest fire alerts if environmental status may involve evidence of a recent fire outbreak. A fuzzy-based controller is implemented to manage (...) the uncertainty related to estimating forest fire occurrence and dynamic update of fuzzy sets is developed to distinguish usual and unusual environmental conditions of every monitored forest area. Merkle trees, AES and hash functions are considered to protect the integrity of environmental data. (shrink)

This book engages with the writings of W.G. Sebald, mediated by perspectives drawn from curriculum and architecture, to explore the theme of unsettling complacency and confront difficult knowledge around trauma, discrimination and destruction. Moving beyond overly instrumentalist and reductive approaches, the authors combine disciplines in a scholarly fashion to encourage readers to stretch their understandings of currere. The chapters exemplify important, timely and complicated conversations centred on ethical response and responsibility, in order to imagine a more just and aesthetically experienced (...) world. In the analysis of bildung as human formation, the book illuminates the pertinent lessons to be learned from the works of Sebald and provokes further investigations into the questions of memory, grief, and limits of language. Through its juxtaposition of curriculum and architecture, and using the prose of Sebald as a prism, the book revitalizes questions about education and ethics, probes the unsettling of complacency, and enables conversation around difficult knowledge and ethical responsibility, as well as offering hope and resolve. An important intervention in standard approaches to understanding currere, this book provides essential context for scholars and educators with interests in the history of education, curriculum studies, cultural studies, memory studies, narrative research, Sebaldian studies, and educational philosophy.

A partir da construção histórica dos três modelos identificados no constitucionalismo latinoamericanopor Roberto Gargarella, o presente trabalho explora o núcleo diferenciador das propostas de organização e exercício do poder de matriz radical (também chamada de republicana), sobretudo por meio do pensamento de José Gervasio Artigas (Uruguai), Francisco de Paula Gonzales Vigil (Peru), Manuel Murillo Toro (Colômbia) e Francisco Bilbao (Chile). Na sequência, busca-se apontar os mecanismos inconciliáveis entre o modelo radical e aquele adotado pela Constituição brasileira vigente, com o fim (...) de evidenciar as mudanças imprescindíveis à verticalização do regime democrático no que diz respeito à organicidade constitucional.

El presente artículo busca dar con la influencia de Baruch Spinoza en el pensamiento de Xavier Zubiri en torno al tema de la materia y de allí entender lo que es lo estético. Es sabido que Zubiri desde joven fue un gran lector de Spinoza; incluso lo enseñaba en detalle a su amiga-estudiante María Zambrano. Y lo que pensamos es que Zubiri siempre estuvo influenciado por el pensador holandés y esto se ve reflejado en cómo Zubiri trata su concepto de (...) materia, clave en su obra; y tal concepto nos permite, por ejemplo, entender lo estético en el pensador español.

Despite the unquestionable importance of technological progress in twenty-first-century society, the decision by many political leaders worldwide to treat natural sciences as an almost exclusive priority betrays a terrible misconception of the complexity of the contemporary world. As the Renaissance cannot be reduced to Copernicus’s or Galileo’s brilliant contributions, or Enlightenment to the works of such giants as Newton and Cavendish, contemporary society will hardly be remembered as just a series of amazing software and gadget updates. There are three categories (...) of questions today that only humanities are prone to answer. The first one, exploring the relations between subject and object mediated by the meaning of “property”, ultimately concerns the discussion between legality and legitimacy. Not long ago, teenagers were still being sued by the giants of the Entertainment Industry for downloading songs, and the practice of mash-ups or remixing even now arouses huge polemics. The second one, focused on the self-representations of the subject, concerns the changing meanings (and representations) of identity and cultural borders in a globalizing world. Finally, the inter-subjective interactions are the centre of the political tensions between democracy and demagogy, two opposed categories that have often been presented as hardly distinguishable from each other.

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.

The COVID-19 pandemic highlights the relevance of adequate decision making at both public health and healthcare levels. A bioethical response to the demand for medical care, supplies and access to critical care is needed. Ethically sound strategies are required for the allocation of increasingly scarce resources, such as rationing critical care beds. In this regard, it is worth mentioning the so-called ‘last bed dilemma’. In this paper, we examine this dilemma, pointing out the main criteria used to solve it and (...) argue that we cannot face these ethical issues as though they are only a dilemma. A more complex ethical view regarding the care of COVID-19 patients that is focused on proportional and ordinary treatments is required. Furthermore, discussions and forward planning are essential because deliberation becomes extremely complex during an emergency and the physicians’ sense of responsibility may be increased if it is faced only as a moral dilemma.

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.

Tomas Aquinas defined truth as the correspondence between things and understanding. Castro Alves paints the horror of the slave nautical traffic. In his essay On the Concept of History, Walter Benjamin reminds us: “The tradition of the oppressed teaches us that the ‘emergency situation’ in which we live is the rule.” This ‘emergency situation’ was Fascism. Albert Camus defended his romance La Peste against the accusation of Roland Barthes that is was “dehors de l’histoire”, pointing out that it was (...) not only about the recent historical phenomenon of Fascism, but also about the permanent risk of its rebirth. Agnes Heller associates faith with prejudice and alienation. The following article will explore the Thomist concept of truth, Benjamin’s concept of history, Camus’ allegory of the plague, Agnes Heller’s notion of faith and Castro Alves’ powerful denouncement of slave traffic, to better criticize the phenomenon of post-truth, a rebirth of fascist information practices.

The iconoclastic Brazilian anthropologist and theoretician Eduardo Viveiros de Castro, well known in his discipline for helping initiate its “ontological turn,” offers a vision of anthropology as “the practice of the permanent decolonization of thought.” After showing that Amazonian and other Amerindian groups inhabit a radically different conceptual universe than ours—in which nature and culture, human and nonhuman, subject and object are conceived in terms that reverse our own—he presents the case for anthropology as the study of such “other” (...) metaphysical schemes, and as the corresponding critique of the concepts imposed on them by the human sciences. Along the way, he spells out the consequences of this anthropology for thinking in general via a major reassessment of the work of Claude Lévi-Strauss, arguments for the continued relevance of Deleuze and Guattari, dialogues with the work of Philippe Descola, Bruno Latour, and Marilyn Strathern, and inventive treatments of problems of ontology, translation, and transformation. Bold, unexpected, and profound, Cannibal Metaphysics is one of the chief works marking anthropology's current return to the theoretical center stage. (shrink)

En este artículo se señalan algunas condiciones que son necesarias para el desarrollo y estabilidad de la democracia contemporánea, las cuales están vinculadas tanto al problema de la limitación de su poder como al de la justicia social. El texto está estructurado en tres partes: en la primera, se presenta un breve panorama de los niveles de apoyo que tiene la democracia en América Latina, destacando en especial las condiciones de desigualdad que hay en México; en la segunda, se analiza (...) la propuesta de Norberto Bobbio, para quien la democracia se caracteriza por ser representativa, política y formal; en la tercera, se recuperan algunos elementos de uno de sus principales discípulos, Luigi Ferrajoli, quien ha señalado la necesidad de la democracia sustancial y los derechos fundamentales para limitar el poder de la democracia formal. Palabras clave: Democracia; derechos fundamentales; desigualdad social Limits of Democracy and Social JusticeIn this article I point out some necessary conditions for the development and stability of contemporary democracy; conditions which are linked to both, the problem of the limitation of its power and social justice. The text is structured into three parts. In the first I present a brief overview of the levels of support that democracy has in Latin America, focusing especially on the inequality conditions existing in Mexico. In the second part I analyze the proposal of Norberto Bobbio´s, for whom democracy is characterized by being representative, political and formal. In the third part, I recall some points dealt with by one of his disciples, Luigi Ferrajoli, who has pointed to the need for substantial democracy and fundamental rights to limit the power of formal democracy.

Este artículo muestra varios detalles para entender la compleja figura de Ariadna en el pensamiento de Nietzsche, pero que va más allá del autor alemán y se sumerge en ciertos momentos de Ariadna, desde lo etimológico a Otto pasando por Ovidio y Catulo, para dar cuenta de una Ariadna que es la compañera del dios Diónysos y que en cierta forma posibilita la propia verdad del dios; lo que Nietzsche llamaría “eterno retorno”.

This article reflects on how the issue of the Real allows us to rethink the human of today in a more complete and up-to-date way. And for this purpose, two apparently dissimilar perspectives of understanding the Real are discussed: that of the Slovenian philosopher Slavoj Žižek, which is rooted in Lacan’s psychoanalysis, and that of the Spanish philosopher Xavier Zubiri, which is born from a deep critical dialogue with Heidegger’s ontology. This paper will show the unity of two visions of (...) the Real that lie at the heart of what is human and that allow us to criticize certain very influential psychoanalytic thought, centred on Jacques-Alain Miller, which cannot account for what is happening to us radically in the current era, or, perhaps, in any era.

Este artigo apresenta a teoria supervalorativista da vagueza e discute a objecção, que frequentemente lhe é dirigida, segundo a qual essa teoria não consegue dar conta do fenómeno da vagueza de ordem superior.

Hablar de infinitud parecería conducirnos a dimensiones abstractas o lejanas; se trataría entonces de un discurso que pertenecería a lo meramente lógico o insustancial. En este estudio se pretende, por el contrario, hablar de la infinitud como realidad, como aquello en lo que estamos y que nos constituye. Pero no se trata solamente de la realidad divina, tardíamente considerada sin embargo como infinita, sino también de la realidad toda, que procede en definitiva de lo divino infinito como de su fuente (...) y sustento radical, y que debido a ello no puede coherentemente ser pensada sino como participando de algún modo de lo infinito originante. La amplia y sutil peripecia especulativa de la reflexión occidental, desde lo griegos hasta la actualidad, sobre la infinitud o no-limitación de la realidad es aquí objeto de atención y análisis sostenidos.

O ensaio tentar realizar um exercício hermenêutico de explicitar os sentidos de tempo que surgem no poema O tempo o homem, do poeta paraense Max Martins. Neste ensaio, as premissas interpretativas partem sobretudo do pensamento do filósofo paraense Benedito Nunes, tendo, no horizonte a Ontologia fundamental de Martin Heidegger, mas também de outros pensadores, como Giorgio Agamben. Além disto, o horizonte hermenêutico deste ensaio alcança um dos poetas que marcaram determinantemente a poesia de Max Marins, que foi seu amigo Mário (...) Faustino. Assim, o problema central desta investigação ensaística é a busca por saber o sentido dos tempos Ampulheta, Era, hera e Hora. A hipótese é que o aporte hermenêutico fenomenológico desenvolvido por Benedito Nunes para a relação dialógica, de “transa”, entre poesia e filosofia, viabilizada pelo que chamou de “passagem para o poético” (Kehre), oferece a tese de que o poema de Max Martins é um poema sobre o próprio poetar e sobre a “aventura” enquanto “evento” (Ereignis) da Hora que o artista faz.

According to Schroeder-Heister 2018, proof-theoretic semantics is ‘an alternative to truth-condition semantics. It is based on the fundamental assumption that the central notion in terms of which meanings are assigned to certain expressions of our language, in particular to logical constants, is that of proof rather than truth. In this sense proof-theoretic semantics is semantics in terms of proof. Proof-theoretic semantics also means the semantics of proofs, i.e. the semantics of entities which describe how we arrive at certain assertions given (...) certain assumptions.' This text advocates that proof-theoretic semantics, as described above, was an approach to semantical issues in logic that appeared in mainstream philosophical literature at least a couple of centuries before the tradition of general proof theory (cf. Prawitz 1971) came into being. This is done by means of an interpretive analysis of Kant’s 1762 essay Die falsche Spitzfindigkeit der vier syllogistischen Figuren, in which two theses are argued: first, that the issue of justifying the logical validity of inferences is approached by Kant in this text, in a strong sense, in terms of proofs; and second, that the purpose of his effort is to establish a point concerning the semantical equivalence between certain distinct valid inferences.

The ἐκπύρωσις, or world's conflagration, followed by the restoration of an identical world seems to go against the rationality of the Stoic god. The aim of this paper is to show that Cleanthes, the second head of the School, can avoid this paradox. According to Cleanthes, the conflagration is an inevitable side-effect of the necessary means used by god to sustain the world. Given that this side-effect is contrary to god's sustaining activity, but unavoidable, god's rationality requires the restoration of (...) an identical world once the conflagration subsides. The paper also deals with the relation between Cleanthes and other early Stoics on the topic of conflagration. In particular, Cleanthes' position seems to differ from Chrysippus'. For in contrast with the Cleanthean god, who causes the conflagration as a side-effect only, the Chrysippean god, according to an influential interpretation put forward by Jaap Mansfeld, causes the conflagration as his ultimate cosmological goal.

This paper briefly presents an account, partially based upon Ryle’s approach, of the functions of intentional psychological terms as they are used in ordinary language. According to this account, intentional psychological terms describe known patterns of behavior that are determined by selective mechanisms of causation. That is, these terms describe relations between certain responses, selected on the basis of the consequences they produce in the environment, and contexts of their occurrence, to which they become associated. Intentional psychological terms do not (...) point to inner causes of a given behavior, but can explain it only in the sense of stating that it could be expected to occur, if we can identify its behavior pattern and the context in which it occurs. We proceed then to examine three main objections that have been raised against Ryle’s position, namely: (a) Davidson’s challenge to the non-causal accounts of reason-explanations; (b) Armstrong’s worries about “leaving the counterfactuals hanging in the air”; and (c) the holistic objection to the (wrongly) presumed Ryle’s atomism. We aim at showing that none of these objections pose serious problems to the proposed account. (shrink)
