Conhecido por textos que promoveram uma concepção autônoma de obra de arte, Karl Philipp Moritz foi também um destacado representante da tradição da psicologia – posições que pareceriam contraditórias a princípio, quando assumimos o desenvolvimento da estética na segunda metade do século XVIII. Seu ensaio Sobre a imitação formadora do belo possibilita, todavia, uma compreensão mais matizada da passagem entre essas perspectivas. Partindo de uma análise psicológica “profunda”, por assim dizer, da produtividade artística, Moritz aponta para uma força plástica e (...) objetiva atuante na subjetividade criadora, anterior à força representativa e dotada de sua própria lógica e linguagem.

In this article, we argue for a study of educational administration centered on an ontology of practices. This is an initial proposal for thinking about and conceptualizing practices in educational administration. To do this, first, we explore how practices are constituted and how they configure the social realities of practitioners. Second, we explore what an ontology of practices has to offer for our understanding of organizations. Third, we examine how an ontology of practices might inform our understandings of leadership in (...) educational organizations, and we conclude by exploring some implications of an ontology of practices for the study of educational administration.

In a context of rapid technological innovation and expensive new products, the paper calls for the generation of real-world data to inform decision-making and an international discussion on the affordability of new medicines, particularly for low- and middle-income countries. Without these, the challenges of health judicialization will continue to grow.

The starting point of any inquiry into the relationship between Frederick and the Arabic-Islamic culture goes back to the Arabic-Norman Sicily to which he was bound by the great Constance, by his infancy, by his early adolescence, and by his crown. Despite the fact that he was born by chance in the Marche region and had preferred to spend his adult years in the flat land of Puglia, where he died, it was in Sicily that he first formed the elements (...) of his intellectual personality and culture. The first question to be answered, therefore, is: How much of the Arabian culture of the late twelfth and early thirteenth centuries was still alive in Sicily after the survival of both the Moslem domination and the political, religious, ethnical, and social crises by which the last Mohammedan influence upon Sicily had been completely eliminated under the last Norman kings?

With the aid of new technologies, science has found creative ways to investigate nature. Through the use of a highly sensitive, low-noise, cooled camera, previously applied to exploring dark sky, scientific laboratories around the world have been looking at the weak emission of light from cells in a living organism. Biophoton emission, as so-called by Fritz Albert Popp, was introduced to science in the 1920s by the Russian embryologist Alexander Gurwitsh, receiving the name of mitogenetic rays. Since 1974, systematic research (...) carried out by Fritz Albert Popp and his colleagues in many parts of the world has been focused on conducting experiments and working towards a biophoton theory to inform us about its properties. One of the main hypotheses is that biophoton plays an important biological function and due to evidence of coherence of its light, i.e. a high degree of order with an extremely stable intensity (Bischof 2005), biophoton is supposed to operate as a biological laser, able to manage a network of information in the organism as well as to form electromagnetic field patterns. Interactive art based on digital technologies uses numerical data to produce interactions between our body and lit pixels on the screen. Maybe, with the correct tools and equations, data from subtle fields of energy in living systems could be used to connect different systems of information, conjugating micro and macro levels of energy. This paper intends to examine biophoton research as a possible model to interactive art and consider the way it could lead to new forms for perception and consciousness. (shrink)

Nesse artigo propomos a análise de um dos eventos presentes no Sutra de Kṣitigarbha, que narra sobre uma das vidas do contínuo do desperto na qual suas aspirações iniciais de beneficiar todos os seres a superarem os renascimentos miseráveis são fortalecidas. Essa análise ocorrerá sob a perspectiva do desenvolvimento da compaixão como explicado por Tsongkhapa no Grande Tratado do Caminho Gradual da Iluminação. Buscaremos assim entender como esse sutra devocional busca estimular o desenvolvimento dessa virtude através de uma narrativa alegórica (...) sobre ações aflitivas, seus resultados nos renascimentos dos seres e práticas que visam beneficiar aqueles que faleceram. Com isso, refletiremos sobre como esse estímulo ao cultivo da compaixão pode auxiliar o praticante a lidar com o luto. (shrink)

A pesquisa a priori se propôs realizar um esboço etnográfico das quatro comunidades quilombolas no médio sertão maranhense, atentando para os elementos intrínsecos da produção de conhecimentos. Como suporte metodológico, as interlocuções seguiram pelo viés dos estudos que privilegiam as alteridades e os saberes locais como pressupostos analíticos fundamentais. Nessa perspectiva, procuramos nos afastar da maioria dos estudos voltados para comunidades quilombolas que trazem como abordagem central, as lutas fundiárias, o reconhecimento por direitos, no entanto, compreendemos que essas abordagens são (...) fundamentais como marco de compreensão das lutas políticas. As comunidades quilombolas aqui pesquisadas somente foram certificadas pela Fundação Palmares no ano 2006, porém há mais de meio século essas comunidades mantém entre si relações de sociabilidade e intercâmbios culturais. Não obstante, a nossa busca de conhecimento está pautada nos saberes, nas trajetórias e nas concepções de espaço social referenciado na alteridade. Dessa forma, procuraremos captar os processos de criatividade cosmopolítica, sociocosmológica e antropológica, dando ênfase para as suas próprias elaboração e construção de conceitos. Para esse fim, o trabalho de campo foi um instrumental metodológico de suma importância, aliado a outras metodologias, por exemplo, a história oral, a etnohistória e os cuidados com a linguagem local, elementos fundamentais inerentes às ciências sociais. Palavras-chave: Quilombolas, Cosmopolítica, médio sertão maranhense. (shrink)

O principal objetivo deste artigo é apresentar uma identidade possível entre os conceitos de forma e de qualidade na filosofia de Charles Sanders Peirce, por meio de seus argumentos em sua Semiótica e em sua Cosmologia. Em outras palavras, nosso objetivo é mostrar que a primeiridade consiste em uma forma, parte constitutiva da natureza da terceiridade, na medida em que a tendência à generalização ou à aquisição de hábitos estava prefigurada na origem do cosmos. De natureza indutiva, o passo do (...) nada absoluto para uma unidade de qualidades prefigura um universo inteligível de natureza formal. Esta unidade já pode ser considerada uma restrição de uma potencialidade de força maior presente naquele nada germinal: a primeira categoria é configurada, então, como sendo de natureza potencial qualitativa. O adjetivo “qualitativa” apresenta uma espécie de restrição da potencialidade para a qual nos referimos: tal potencial é desta ou daquela espécie. A segunda categoria, por sua vez, surge de um caos de sentimentos: não é a interação entre tais sentimentos que traz a segunda categoria à realidade, mas a mera manifestação do sentimento que é, por sua vez, caracterizado como a aparência momentânea da qualidade. Esta aparência não é potencial, mas atual. Ela já é um fato; ela já é uma restrição da potencialidade qualitativa. Sentimento enquanto atualidade e qualidade em seu estado potencial prefiguram a origem do outro que se apresenta: este outro está, portanto, inscrito na natureza da qualidade e já apresenta a dualidade objeto e objeto representado. Por fim, a tendência à generalização é reconhecida por meio das relações que as qualidades estabelecem entre si: na medida em que o aparecimento de uma ou mais qualidades se manteve insistente, tais qualidades começaram a estabelecer relações entre si, permitindo a formação indutiva de leis e objetos mais complexos, mas sempre devedores do material disponível prefigurado na origem: qualidades.

The world today is facing unprecedented challenges of governance far beyond what the United Nations, established more than 70 years ago, was designed to face. The grave effects of global climate change are already manifesting themselves, requiring rapid, far-reaching and unprecedented changes in all aspects of society if we are to arrest catastrophic and probably irreversible consequences. Science has uncovered the frightening and rapid collapse in global biodiversity, threatening ecosystems across the planet that maintain the correct functioning of the biosphere, (...) upon which we rely for survival. But there is more; there are other global catastrophic risks. We live in a world in which a diminished faith in our political leaders and governmental structures, public disillusionment with partisan politics and a willingness to believe populist promises, disturbing trends in income inequality, human rights violations and the spread of corruption have coincided with the rise of autocratic leaders, often intent on awakening the voices of nationalisms which have been so destructive during the 20th century. The rejection by some nations of the benefits of multilaterism and international cooperation, which have been at the center of the postwar global order, has heightened the risks of fundamental instabilities that could precipitate a range of major crises, disregarding the lessons of the past.

This article introduces practical and theoretical investigations in fields of art and technology related to biotelematics, hybridization and transcultural experimentation based on research carried out over the last four years at the Nucleus of Art and New Organisms (NANO). We will approach this subject by considering three main points of view: field theory (Ascott 1980; Nóbrega 2009); the concept of coherence (Ho 1993; Ho & Popp 1989; Simondon 1980); and the state of connectedness (Ascott 2006). These will act as integrative (...) models for the understanding of an emerging hybrid organic structure presented as an aesthetic organism (Nóbrega 2009). The concept of field theory is applied as a working model for the systemic role of information within the immaterial, invisible, dynamical flow that intercommunicates natural (i.e. humans and other living systems) and artificial (i.e. machine) organisms in the process of invention, as well as in the fruition of artwork. In terms of the concept of coherence, we propose the idea of artworks as transducers of energy; more specifically, as resonators of coherent fields that interconnect the artist and audience in an integrated, dynamical whole. Furthermore, we approach the state of connectedness as a fundamental notion for the dynamics involved in the invention, exhibition and absorption of contemporary artworks. NANO Lab’s involvement with artistic research is not only understood as a physical space for experimentation, but also as an environment in which our practice reflects concepts applied in artistic work. In this sense, we can highlight two theoretical references (other than Roy Ascott’s work) which guide this methodology: Humberto Maturana (2001; Varela & Maturana 1992) and the idea of a conserved ‘autopoiesis’, a systematic medium (space) in which all recursive dynamics of reciprocal interactions occur to sustain the survival of life, processes and systems, and where technology can be conceived as a powerful instrument/medium to expand our knowledge about structural and sensitive coherences within living and non-living systems; and, Jorge de Albuquerque Vieira’s (2006; 2009) approach to art as a type of knowledge related to any process that guarantees the permanence or survival of a system based on three major characteristics for the survival of an open system – sensitivity (to operate information flows), memory (to transfer and retain information), and capability (to elaborate or prepare information according to its needs).

The aim of this paper is to examine the theoretical status of the hegelian concept of freedom as “being with oneself in one’s other”, as well as the mediation of the category of recognition in the relationship between the objective and subjective face that this concept portrays. In this perspective, no legitimate relations of domination and coercion are rejected on behalf of a intersubjective concept of freedom. The aim is also to highlight the important elements in the hegelian philosophy to (...) understand the meaning of freedom in the constitution of a social theory, which can be expressed in its approximation to the republicanism, in contemporary discussion of political and moral philosophy.

RESUMO Este artigo, um recorte de nossa dissertação de mestrado, tem como objetivo apresentar uma análise da peça A última gravação de Krapp, de Samuel Beckett, a partir de conceitos teóricos provenientes dos escritos do teórico da literatura russo Mikhail Bakhtin, tais como dialogismo, polifonia, cronotopo e grotesco. Com o intuito de problematizar a questão das vozes presentes na peça, de acordo com a estrutura dramatúrgica criada por Samuel Beckett, tais conceitos servirão de suporte para uma reflexão que busque compreender (...) a questão das relações existentes entre Krapp e suas alteridades; os jogos e conflitos desenvolvidos entre as diferentes consciências dos diferentes Krapps presentes no texto a partir da materialidade de suas gravações; a questão do espaço-tempo proposto por Beckett na peça; bem como a caracterização grotesca de Krapp e sua relação com a gênese do personagem, dentro do que denominamos, em nossa pesquisa, de poética do fracasso. Este trabalho foi originalmente apresentado como parte de nossa dissertação de mestrado1. ABSTRACT This article aims to present an analysis of Samuel Beckett’s Krapp’s Last Tape, based on theoretical concepts from the writings of Russian literature theorist Mikhail Bakhtin, such as dialogism, polyphony, chronotope and grotesque in order to investigate the voices present in the play, according to the dramaturgical structure created by Samuel Beckett. Such concepts will serve as a support for a reflection that seeks to understand the relations between Krapp and his alterities as well as the games and conflicts developed through the different selves of the different Krapps present in the text, sprung from the materiality of his recordings. It will focus on the space-time question proposed by Beckett in the play, as well as the grotesque characterization of Krapp and its relation to the genesis of the character, within what we call in our research of poetics of failure. This work was originally presented as part of our master’s thesis.1. (shrink)

Este artículo se refiere a la doctrina práctica de Aquino sobre dos dificultades filosóficas que subyacen en gran parte del debate ético contemporáneo. Una es la Is-ought thesis de Hume y la otra es su consecuencia radical la Open-question argument de Moore. Estas paradojas éticas parecen tener sus raíces en un scepticismo epistemológico y en una antropología deficiente. La posible respuesta a ellas se puede encontrar en que: a) Tomás de Aquino defiende la esencial racionalidad y unidad del ser humano; (...) b) La ley natural tomista es una consecuencia natural del ser racional; c) La razón humana es esencialmente teórica y práctica al mismotiempo. El intelecto humano de Aquino naturalmente realiza tres operaciones principales: 1º) Aprehender las nociones inteligidas y universales ens, verum y bonum. 2º) Formular los primeros principios teóricos y prácticos. 3º) Ordenar que se haga el bien inteligido y universal y se evite lo contrario. Por estas razones,la respuesta filosófica de Aquino a ambas dificultades no es exclusivamente ética, sino que abarca armónicamente la ontología, antropología y epistemología. La ética de Tomás de Aquino es fundamentalmente diferente de las éticas que califican las acciones como buenas o por mero consenso social (contractualismo) o simplemente calculando sus consecuencias (consecuencialismo).

O tema central desta monografia é a noção de realidade, tal como esta foi entendida por alguns cientistas naturais da primeira metade do século XX. Os cientistas-filósofos escolhidos são: Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger e Max Born. À guisa de comentário introdutório, devo observar que o tema da realidade não é o único aqui abordado, e que a presente monografia pode ser tomada como uma primeira introdução às ideias e teses filosóficas dos seis cientistas referidos. (...) Ao escrever este trabalho, o meu principal objetivo foi o de fazer com que os estudantes de graduação dos cursos de filosofia tenham a possibilidade de ler um comentário geral sobre as ideias filosóficas – em particular, as metafísicas, portanto referentes à natureza da realidade – de alguns dos físicos mais importantes do século passado. Um segundo público alvo possível pode ser encontrado entre os estudantes do ensino médio. Finalmente, este texto pode, eventualmente, ser definido como paradidático, atraindo a atenção de professores, principalmente daqueles que atuam neste último segmento. (shrink)

O objectivo do presente artigo é apresentar as ideias que o físico teórico austríaco Ludwig Boltzmann (1844-1906) desenvolveu acerca da natureza e do papel das leis do pensamento. Muito influenciado por Charles Darwin, Boltzmann recusou-se a compreender as leis do pensamento segundo a filosofia de Kant. Em particular, Boltzmann defendeu uma concepção evolutiva das leis do pensamento. O artigo mostra de que forma a concepção das leis do pensamento aceite por Boltzmann impôs uma transformação da sua ideia sobre aquilo que (...) seria o próprio da filosofia. /// Aim of this article is to show some of the epistemological ideas developed by Ludwig Bolzmann (1844-1906). The author of the article considers in particular Bolzmann's view on the nature and role of the laws of reason in the construction of scientific theories. Moreover, he also analyses the influence of Charles Darwin on the Austrian theoretical physicist and how this influence can be viewed as the turning point for the definition of Boltzmann's conception of philosophy.

This book explores the concept of the end of literature through the lens of Hegel's philosophy of art. In his version of Hegel's 'end of art' thesis, Arthur Danto claimed that contemporary art has abandoned its distinctive sensitive and emotive features to become increasingly reflective. Contemporary art has become a question of philosophical reflection on itself and on the world, thus producing an epochal change in art history. The core idea of this book is that this thesis applies quite well (...) to all forms of art except one, namely literature: literature resists its 'end'. Unlike other arts, which have experienced significant fractures in the contemporary world, Campana proposes that literature has always known how to renew itself in order to retain its distinguishing features, so much so that in a way it has always come to terms with its own end. Analysing the distinct character of literature, this book proposes a new and original interpretation of the 'end of art' thesis, showing how it can be used as a key conceptual framework to understand the contemporary novel.

Considering dialogue as a fundamental philosophical experience, this paper aims to understand the possibility of a radical and emphatic dialogic practice in the formation of the educator-philosopher. “Educator-philosopher” is the term used to detach the importance of a dialogic specialization in philosophy so that the teacher’s teaching practice becomes a philosophical activity, and he finds himself as a philosopher in the ways of philosophy. The transdisciplinary perspective announced is configured as an epistemologic field of a dialogue methodology practiced at all (...) ages of basic education. It has to do with an understanding of philosophy as an apprenticeship of appropriative thinking, which requires of the educator-philosopher a radical transformation, because only the one who learned to be a philosopher – the one who learned to investigate the "what" of things, investigating thoughts themselves – can favor the event of a dialogic practice whose focus is the apprenticeship of the articulator thought: to learn to learn with the seriousness of a child.

Markus Gabriel's pluralism and Graham Priest's monism can be considered new forms of skepticism in contemporary philosophy. Gabriel considers 'emptiness' and Priest 'nothingness' as safe havens for logic and philosophy. Similarly, traditional skeptics also considered nothing secure. Furthermore, we can also observe in this book that both Priest and Gabriel present quite eloquent theories, even though they still lack more substantial proofs, much like many important theories in philosophy, such as Leibniz's monadology.

L'uomo è un animale razionale, oltreché politico, socievole, come dice Aristotele. Ma quello del pensiero occidentale è un cammino, non sempre lineare, lungo momenti di apertura e ripiegamento della ragione. Quando la ragione è strumento del conoscere è in una fase di apertura, in cui fioriscono le scoperte scientifiche, l'arte, il pensiero politico ed economico; quando invece la stessa ragione perde il suo carattere strumentale divenendo pensiero assoluto, ripiegato su di sé, cede il passo alla follia, fino agli orrori del (...) Nazismo. La follia è il capitolo oscuro di un logos assolutizzato, che non lascia spazio alla molteplicità dei punti di vista, è la deriva di una ragione non 'addomesticata', privata del contraddittorio con il reale. Con un linguaggio preciso ma accessibile, Campana Comparini, al dualismo ragione 'aperta' e feconda/ragione 'chiusa' e assolutizzata, oppone una diversa categoria filosofica di lettura del reale: la follia della croce; ovvero una prospettiva in cui la fede nel Cristo-uomo diventa la base da cui partire per rifondare la principale caratteristica dell'uomo, cioè il pensiero. La 'follia della croce' non è tanto un'alternativa, quanto il terreno su cui reimpiantare la logica della razionalità umana, poiché viene prima di essa. Una lettura per guardare da un'altra prospettiva le origini del pensiero occidentale."--Page 4 of cover. (shrink)

O artigo apresenta o resultado da pesquisa que abordou a investigação sobre as rupturas epistemológicas e o discurso sobre Deus na obra As palavras e as coisas , de Michel Foucault. Intitulada como "Deus, as palavras e as coisas", a pesquisa parcialmente apresentada aqui pretende ser uma colaboração para a análise do que se tem identificado como fenômeno do neo-ateísmo, um tema de grande relevância para a Filosofia da Religião nos dias atuais. Para compreendê-lo, apresentam-se, seguindo a perspectiva foucaultiana, os (...) distintos matizes epistemológicos que sustentam a concepção sobre Deus. Em seus três momentos, o texto apresenta a episteme renascentista e o discurso de Deus, a episteme clássica e a idéia sobre Deus e, por fim, a episteme moderna, a morte de Deus e a morte do homem. Acredita-se que aquilo que se decide na contemporaneidade não seja necessariamente o acabamento do tempo da morte de Deus e a consequente morte do homem, fruto do modo moderno de compreender e tematizar o divino, o infinito, o absoluto ou o verdadeiro, mas uma clara disputa entre variadas perspectivas epistemológicas em suas concretizações científica, política, cultural e religiosa. Palavras-chaves: Michel Foucault, Filosofia da Religião, Epistemologia, Deus, Ateísmo.The article presents the results of research that investigate on epistemological ruptures and speaking about God in The Order of Things writhed by Michel Foucault. Entitled as "God, words and things," this research partially presented here is intended as collaboration for the analysis of what has been identified as phenomenon of neo-atheism, a topic very important for the Philosophy of Religion today. To understand it, we present, following the Foucaultian perspective, the different epistemological nuances underpinning conception of God. In her three moments, the text presents the Renaissance episteme and the God's discourse, the classical episteme and the idea of God and, finally, the modern episteme , the death of God and man's death. It is believed that what is decided in the contemporary is not necessarily the finish time of the death of God and the consequent man's death, the fruit of modern way of understanding and themes on the divine, the infinite, the absolute or true, but a clear dispute between different epistemological perspectives in their political, cultural and religious diversity achievements.

Cet article explore la notion hégélienne d’« arts imparfaits » (comme le jardinage ou la danse) qu’il considère comme étant à la marge du système conventionnel des arts, ne leur reconnaissant pas pleinement le statut d’arts. L’objectif est d’examiner les caractéristiques qui spécifient ces arts et les raisons de leur « exclusion » du système artistique établi. L’hypothèse avancée est que les traits que Hegel attribue à ces formes d’expression artistique, ainsi que leur « excentricité » par rapport aux œuvres (...) d’art canoniques, ont des éléments communs avec certaines formes d’art contemporaines, qui ont remis en question le système artistique traditionnel de manière radicale (land art, art in situ, performance art, etc.). Après avoir abordé la question générale du système des arts, en décrivant sa dimension philosophique et la position de Hegel à son égard, l’article se concentre sur les soi-disant arts imparfaits, et rend compte de l’« exclusion » de ces arts de la catégorie des arts proprement dits en explicitant la logique structurante du système des arts. Il examine ensuite deux exemples notables, à savoir le jardinage et la danse, en identifiant des éléments communs qui justifient à la fois leur « excentricité » et leur « exclusion » du système. Il explicite ensuite les raisons de l’imperfection de ces arts, que sont l’excès de nature et leur aspect indéterminé et hybride. Il esquisse en conclusion des pistes pour penser une interaction entre la perspective hégélienne et notre contexte artistique contemporain. (shrink)

This paper addresses the way Hegel determines the difference between poetry (i.e., literature) and history. Hegel’s position is particularly significant for understanding both the basic features of the two fields and the implications that their relationship generates, even in contemporary debates. Starting from a comparison with Aristotle’s fundamental position, I will show how the Hegelian proposal, while initially appearing akin to that of the Greek philosopher, actually differs profoundly from it. This divergence has to do with their different conceptions of (...) the relationship between the two disciplines and philosophy. Unlike Aristotle, for Hegel history is more philosophical than poetry, because, to be genuinely history, it must itself become philosophy. At the same time, if poetry becomes philosophy, it loses its specificity and ceases to be art. To reach this determination, I will show that the key factors concern how the individual practice of the two disciplines is conceived and, more importantly, the different ways they relate to universality.

After a long period during which the involvement of laypersons was considered undesirable in the Western tradition of science, we have recently witnessed numerous collaborations which suggest that the desirability of societal involvement in the scientific practice is becoming recognized. This article argues that the historical considerations that once led to this division in cognitive labour have been in transformation, having undergone diverse shifts. In a first instance, the exclusion of laypersons from science is analysed in terms of the key (...) concepts of systematicity, universality, and authority. For that, two examples are given: the case of the British photographic survey and that of the American Museum of Natural History. Next, the dissolution of these barriers between scientists and laypersons is discussed and illustrated by examples: the Dystrophic Epidermolysis Bullosa Research Association in Austria, Fukushima nuclear monitoring stations, and the French Association of Muscular Dystrophy. It is concluded that, for science to be truly democratized, co-produced knowledge needs to be integrated in political decision-making processes, which is currently still lacking. Furthermore, since expertise can also be found in society, non-certified experts should work in conjunction with scientists, yet at the same time, the divide between experts and non-experts must be maintained. The inclusion of non-scientific experts in decision-making is fundamentally different from the inclusion of lay stakeholders. Hence, different participatory roles should be expected from stakeholders, experts, or scientists, and the most important challenge now is how to formally define such roles. (shrink)

Este ensayo es producto de una investigación en el campo de la teoría e historia del arte y se concentra en el análisis de la pintura inédita Escena de dormitorio (c.1985-86) del destacado escritor y pintor chileno Adolfo Couve Rioseco (1940-1998). La obra salió a la luz en 2021, y su estudio no solo permite abordar problemas relativos a autoría, data, técnica y gestos pictóricos, sino también comentar los espacios domésticos y las relaciones familiares del autor. Sobre todo, permite profundizar (...) en sus filiaciones visuales; en este caso puntual, su interés por óleos tales como Jeremías lamentando la destrucción de Jerusalén (1630) de Rembrandt van Rijn; una de las cuatro versiones de El muchacho del chaleco rojo (c.1889-90) de Paul Cézanne, y las naturalezas muertas del italiano Giorgio Morandi, a partir de los cuales probablemente Couve construyó el cuadro hasta ahora no documentado que aquí se somete a escrutinio.

In this note, the problem of tracking random references and rejecting random perturbations in a quadrotor, both generated by an auxiliary system named exosystem, is solved by extending the deterministic tracking problem to the area of stochastic processes. Besides, it is considered that only a part of the state vector of the quadrotor is available through measurements. As a consequence, the state vector of the plant must be estimated in order to close the control loop. On this basis, a controller (...) to track random references and to reject random perturbations is developed by combining a Kalman filter to estimate the references and perturbations of an exosystem and an observer to estimate the states of a quadrotor. Besides, to obtain a more practical controller, the analysis is carried out in discrete time. Numerical simulations are used in a quadrotor to confirm the validity and effectiveness of the proposed control. (shrink)

A close look at the Jesuit and Catholic recusant network that existed in the English midlands yields a pathway to the Chandos portrait of Shakespeare. The portrait is traced from the 3rd Duke of Chandos to Grafton Manor, seat of the Shrewsbury earls and a principal Jesuit center in the Jesuit district comprising Worcestershire and Warwickshire created in 1623. The article finds that during Shakespeare’s lifetime, Grafton Manor was owned by a Catholic recusant member of the Talbot family with ownership (...) ties to Welbeck Abbey located in the small township of Holbeck, Nottinghamshire; the parish of Holbeck included Welbeck Abbey and the adjacent Holbeck Hall, which was owned by the family that sheltered Edmund Campion and which served later as home to a major Jesuit library and as a shelter for Jesuits themselves. Keeping in mind Shakespeare’s indebtedness to North family writings as source material for the plays, the article finds that the provenance of an unpublished manuscript by George North which influenced Shakespeare, the manuscript’s content, and George North’s circle of acquaintances lead directly to Edmund Campion and the Pierrepont family that sheltered him before his execution by the crown in 1581. The article shows ties of the George North manuscript to Welbeck Abbey, ties of the North family to the nearby Wroxton Abbey, and possible ties of the alleged painter of the Chandos portrait to the North family at Wroxton Abbey. The article is written in response to the recently published book by Dennis McCarthy and June Schlueter on the discovery of an unpublished manuscript written by George North that they believe inspired Shakespeare. Further shown through parallel language and thought that George North in writing A Brief Discourse likely drew material from Campion’s Histories of Ireland, including material that eventually led to the episodes on Jack Cade in 2 Henry VI and the Merlin prophecy in King Lear—all before Campion’s Histories was absorbed by Holinshed’s Chronicles and ultimately absorbed by Shakespeare. The article, utilizing research by an eminent Jesuit historian showing a personally advantageous relationship between George North’s patron, the Queen’s favored Sir Christopher Hatton, and the Jesuit William Crichton, traces the Shakespeare First Folio discovered on the Isle of Bute in 2016 back through time to the North family and ultimately to the Jesuit Crichton. In consideration of a probable biographical relationship between Shakespeare and Hatton, another connection between Shakespeare and the Jesuits is revealed. Lastly, the article details textual support for the author’s previous research showing a relationship between the writings of the Jesuit John Floyd and the Shakespearean canon—hinting that Shakespeare assisted the Jesuits.
