Adaptive optics are techniques used for processing the spatial resolution of astronomical images taken from large ground-based telescopes. In this work, computational results are presented for a modified curvature sensor, the tomographic pupil image wavefront sensor, which measures the turbulence of the atmosphere, expressed in terms of an expansion over Zernike polynomials. Convolutional neural networks are presented as an alternative to the TPI-WFS reconstruction. This technique is a machine learning model of the family of artificial neural networks, which are widely (...) known for its performance as modeling and prediction technique in complex systems. Results obtained from the reconstruction of the networks are compared with the TPI-WFS reconstruction by estimating errors and optical measurements. The reconstructed wavefronts from both techniques are compared for wavefronts of 153 Zernike modes. For this case, a detailed comparison and grid search to find the most suitable neural network is performed, searching between multi-layer perceptron, CNN and recurrent networks topologies. In general, the best network was a CNN trained for TPI-WFS reconstruction, achieving better performance than the reconstruction software from TPI-WFS in most of the turbulent profiles, but the most significant improvements were found for higher turbulent profiles that have the lowest r0 values.

Pretendo mostrar que, no diálogo Leis, Platão apresenta um lado útil e benéfico da comédia, que é quando ela opera com o que chamo de riso lúdico, isto é, um tipo de riso que é uma brincadeira, que não se radica na animosidade ou na inveja. Uma comédia que seja capaz de oferecer esse tal riso lúdico revelar-se-á importante para a educação da cidade, uma vez que capacita os cidadãos a identificar o que é o ridículo, de modo a evitá-lo, (...) pois é somente conhecendo o ridículo que se é capaz de apreender o que é sério. Palavras-chave: Platão; Educação; Riso lúdico; Comédia. (shrink)

O presente artigo pretende homenagear o texto “O futuro ausente: para a crítica da política e o resgate da emancipação humana”, de José Chasin, resgatando e desenvolvendo suas análises da obra marxiana, no que se refere à crítica da política. Parte-se do caminho de pesquisa aberto por Chasin, registrados sobretudo em Marx: estatuto ontológico e resolução metodológica e Marx: a determinação ontonegativa da politicidade, procurando mostrar, por meio da análise imanente da obra marxiana, como o reconhecimento da determinação ontonegativa da (...) politicidade permanece central para a crítica de Marx em sua obra madura, aprimorada pela análise que o filósofo alemão desenvolve sobre a forma valor.

O artigo propõe uma interlocução entre o filósofo francês Michel Foucault e o filósofo norte-americano Richard Rorty. Apresenta a descrição que Rorty realizou do colega francês. Analisa essa leitura e oferece, a partir do próprio Foucault, uma interpretação alternativa, que aponta para algumas imprecisões cometidas por Rorty, em sua interpretação. Conclui com um comentário sobre a conversação proposta.

You think you're human. But what does that mean? How can humanity be defined? Felipe Fernandez-Armesto takes us on an enlightening and provocative journey through the history of humankind to reveal the challenges to our most fundamental belief - that we are, and have always been, human. Fernandez-Armesto investigates advances in artificial intelligence and genetics, and asks what these mean for the future of human values, human rights, and the defence of human dignity. The book illustrates how our concept (...) of humankind has changed over time and how our current understanding of this has been shaken by new challenges from science and philosophy. (shrink)

El timbre general de los documentos implicados en el actual proceso de reforma educativa oscila entre la apología y el tecnocratismo, permaneciendo a la sombra de la discusión, por lo que al ámbito académico respecta, las más de las veces, el papel que la Universidad jugará como motor de la investigación y la innovación tecnológica en la dinámica competitiva de los grandes bloques capitalistas. Estos textos deben ser leídos en su contexto social, político y económico, así como confrontados a la (...) luz, o más bien a la oscuridad, de documentos de la Comisión Europea relativos a las políticas de convergencia y competitividad económica. Las siguientes... líneas acotan con gran precisión el contexto de la reforma: "Los poderes públicos, para asumir sus responsabilidades deben apoyar el desarrollo de los mercados del futuro y prever los ajustes en vez de sufrirlos. La Unión Europea debe situar mejor su capital científico y tecnológico al servicio de la competitividad industrial y de las necesidades de los mercados. Conviene prestar mayor atención a la difusión de los resultados de la innovación, su transferencia y su valorización por la industria y actualizar la distinción tradicional entre investigación fundamental, investigación precompetitiva e investigación aplicada para evitar lo que ha ocurrido en algunas ocasiones en el sentido de que la industria europea no siempre ha podido beneficiarse de todos los esfuerzos efectuados en materia de investigación" 1. Según creemos, el actual proceso de convergencia persigue la conversión de la educación superior en una mera función de la reproducción capitalista. The general tone of documents that relate to the actual education reform process oscillates between self-defense and technocratism. In academic circles, far from debate, the university is regarded as being the engine of investigation and the innovative technology that will be employed by large capitalist groups in their fields of dynamic competition. These texts should be read in their social, political and economic contexts and should be compared with the clarity or perhaps obscurity of European Commission papers written on convergence and economic competitiveness. We believe that the present convergence process is designed to promote further education as a mere tool to be used in capitalist reproduction. (shrink)

In this work we define, in a general way, an algebraic semantics for the logics of the hierarchy InPk. This semantics is defined by means of an alternative construction, with respect to the usual algebraic semantics, and it is known in the literature as Twist-structures semantics. Besides that, we modify such construction, defining the so-called ω-Twist-structures here. This adaptation allows us to prove adequacy theorems for every logic of the hierarchy InPk.

_"A stimulating history of how the imagination interacted with its sibling psychological faculties—emotion, perception and reason—to shape the history of human mental life."—_The __Wall Street Journal__ To imagine—to see what is not there—is the startling ability that has fueled human development and innovation through the centuries. As a species we stand alone in our remarkable capacity to refashion the world after the picture in our minds. Traversing the realms of science, politics, religion, culture, philosophy, and history, Felipe Fernández-Armesto (...) reveals the thrilling and disquieting tales of our imaginative leaps—from the first _Homo sapiens_ to the present day. Through groundbreaking insights in cognitive science, Fernández-Armesto explores how and why we have ideas in the first place, providing a tantalizing glimpse into who we are and what we might yet accomplish. Unearthing historical evidence, he begins by reconstructing the thoughts of our Paleolithic ancestors to reveal the subtlety and profundity of the thinking of early humans. A masterful paean to the human imagination from a wonderfully elegant thinker, _Out of Our Minds_ shows that bad ideas are often more influential than good ones; that the oldest recoverable thoughts include some of the best; that ideas of Western origin often issued from exchanges with the wider world; and that the pace of innovative thinking is under threat.

Industrial development in recent decades has led to using information and communication technologies to support personnel selection processes. One of the most notable examples is game-related assessments, supposedly as accurate as conventional tests but which generate better applicant reactions and reduce the likelihood of adverse impact and faking. However, such claims still lack scientific support. Given practitioners’ increasing use of GRA, this article reviews the scientific literature on gamification applied to personnel selection to determine whether the current state of the (...) art supports their use in professional practice and identify specific aspects on which future research should focus. Following the PRISMA model, a search was carried out in the Web of Science and Scopus databases, identifying 34 valid articles, of which 85.3% are empirical studies that analyze five areas: validity; applicant reactions; design of GRA; personal characteristics and GRA; and adverse impact and faking. Together, these studies show that GRA can be used in personnel selection but that the supposed advantages of GRA over conventional tests are fewer than imagined. The results also suggest several aspects on which research should focus, which could help define the situations in which the use of GRA may be recommended. (shrink)

La reciente proliferación de lecturas fragmentarias de la obra de Simondon exige una interpretación que entienda su carácter sistemático. Consideramos que la allagmática es uno de los problemas fundamentales de su obra y que, sin embargo, apenas ha sido tratado o tomado en serio. La siguiente publicación parte de las profundidades de obra de Simondon y busca encontrar lo particular de esa «ciencia buscada» a la que llama allagmática.

This study tested the direct effects of Dark Tetrad traits on organizational and interpersonal counterproductive work behaviors. We also examined the moderating effects of the three dimensions of organizational justice – distributive justice, procedural justice, and interactional justice – on the Dark Tetrad-CWBs relationships. Based on the data from 613 employees across different occupations, the results revealed that only psychopathy and sadism had significant effects on CWBs targeted at the organization. The results also supported the direct effect of sadism on (...) interpersonal CWBs. The findings confirmed the moderating role of interactional justice but differentially, depending on the dark trait and the target of workplace deviance. Whereas low and medium levels of interactional justice moderated the relationship between Machiavellianism and CWBs directed to the organization, it did not play any role in narcissism, psychopathy, and sadism. Regarding CWBs aimed at other people, interactional justice emerged as a significant moderator in Machiavellianism and sadism. But, whereas sadistic employees performed more harmful behaviors toward other individuals whatever their level of interactional justice, if people high in Machiavellianism perceived a high fair interpersonal treatment, they did not show deviant behaviors directed at other employees. The paper concludes with some suggestions and recommendations about the relevance of organizational justice in the influence of dark personality traits on CWBs. (shrink)

O presente artigo analisa duas correntes de crítica à religião em âmbito filosófico, características da segunda metade do século XX. Primeiramente, a perspectiva do filósofo francês e ex-professor da Sorbonne e de Nanterre, Jean-François Lyotard (1924-1998). Em segundo lugar, as posições inspiradas nos slogans da revolução de Maio de 68. Por fim, procura-se evidenciar as raízes, singularidades e semelhanças entre as duas posturas. /// This article analyzes two currents of religious critique in the philosophical ambit, characteristic of the second half (...) of the twentieth century.

This article examines the third objection of Chapter Five of the opusculum De unitate intellectus of Saint Thomas. This section offers a summary of Thomist gnoseology and the most important arguments regarding the unity of the intellect. It also represents a true milestone in Western Philosophy, by specifying the object of intellection and the distinction between id quod intelligitur and in quo intelligitur, fundamental themes in the context of moderate realism in comparison with the other currents of the theory of (...) knowledge.

Resumo: A honra foi amplamente tratada por diversos autores antigos, tais como Aristóteles e Cícero. No medievo, Tomás de Aquino retoma alguns temas da Antiguidade, oferecendo uma formulação nova. Para isso, ele se serve do conceito de dulia, superando o tradicional binômio com a latria. Na realidade, ele reputa à dulia uma virtude anexa à justiça que visa prestar honras ou homenagens aos homens excelentes, em particular aos virtuosos. De fato, o Estagirita já considerava a honra como um “prêmio da (...) virtude”. Nesse contexto, se percorre todo corpus thomisticum para analisar o conceito de dulia e de honra, quando esta se refere ao assunto tratado. Para isso, se pergunta o que é a dulia propriamente, a quem deve ela ser prestada, se a honra pode ou deve ser desejada, o papel da magnanimidade, como e para que se honra. A proposta tomasiana poderia trazer um novo olhar a respeito da temática, infelizmente um pouco esquecida nos dias de hoje.: Honor was amply dealt with by several ancient authors such as Aristotle and Cicero. In the Middle Ages, Thomas Aquinas revisited certain themes from Antiquity, offering new formulations. To do this, he used the concept of dulia, going beyond the traditional contrast with latria. He regards dulia as a virtue connected to justice and that seeks to pay honour or homage to excellent men, particularly virtuous ones. In fact, Aristotle already regarded honour as a “reward for virtue”. In this article, the body of Thomistic work is explored in order to analyse the concept of dulia and honour. To this end, it is asked what dulia truly is, to whom it should be rendered, whether honour can or should be desired, what the role of magnanimity is, and how honour should be shown and for what. The Thomistic proposal offers a new outlook on a subject which, unfortunately, has been somewhat neglected in the present day. (shrink)

"Do I believe to understand or do I understand to believe? From an analysis of chapters II and III of Fides et ratio, and the texts of St. Thomas Aquinas, an analysis is sought that aims to offer a response that reconciles these two ambits within an anthropological perspective.".

No anseio de compreender a verdade divina, Santo Anselmo, em seu Proslogion, desenvolve o célebre unum argumentum a respeito da existência de Deus. Na segunda parte da obra, ao expressar-se sobre os atributos divinos e sobre as antinomias que se lhe apresentam, o Doutor Magnífico surpreende o leitor com a revelação de que Deus é summe sensibilis — sumamente sensível. Parte-se então de duas visualizações: a possibilidade de Deus ser sensível em si mesmo (secundum se), ou em relação a nós (...) (secundum nos); isto é, da possibilidade de Deus sentir, embora carecendo de sentidos, e da possibilidade de O sentirmos, sendo Ele incorpóreo. Por fim, o artigo focaliza a questão de Deus ser sensível através das criaturas e da reconfiguração da sensibilidade humana no encontro com o Sumo Ser na bem-aventurança. /// "With the desire to understand divine truth, Saint Anselm, in his Proslogion, develops his celebrated unum argumentum with respect to the existence of God. In the second part of the work, in discussing the divine attributes and the antinomies that appear, the Magnificent Doctor surprises the reader with the revelation that God is summe sensibilis — supremely sensible. This is broken down into two visualizations: the possibility of God being sensible in Himself (secundum se), or in relation to us (secundum nos); that is, the possibility of God sensing, despite lacking senses, and our possibility of sensing Him, He being incorporeal. Finally, the article focuses on the question of God being sensible through creatures and the reconfiguration of human sensibility in the encounter with the Supreme Being in blessedness.". (shrink)
