This paper revisits one of the first models of analog computation, the General Purpose Analog Computer . In particular, we restrict our attention to the improved model presented in [11] and we show that it can be further refined. With this we prove the following: the previous model can be simplified; it admits extensions having close connections with the class of smooth continuous time dynamical systems. As a consequence, we conclude that some of these extensions achieve Turing universality. Finally, it (...) is shown that if we introduce a new notion of computability for the GPAC, based on ideas from computable analysis, then one can compute transcendentally transcendental functions such as the Gamma function or Riemann's Zeta function.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Rethinking Music Education and Social Change by Alexandra Kertz-WelzelGraça MotaAlexandra Kertz-Welzel, Rethinking Music Education and Social Change (Oxford: Oxford University Press, 2022)I began to read this book shortly after the invasion of Ukraine by the Russian troops. Amidst this most terrible and brutal context, reading and re-reading the book that Alexandra Kertz-Welzel offers was both a blessing and an intense exercise of food for thought. A blessing as (...) it drives our minds through a complex but nonetheless rewarding journey into the meanders of critical and ideal visions. An exercise of food for thought as she turns to the arts, philosophy, sociology, and political theory to construct an interdisciplinary, sustained story. While rethinking “the goals of music education in view of social change,”1 the introduction describes the purpose of the study and presents the author’s chosen theoretical pillars: Levitas’s concept of utopia, Georgina Born’s four planes of music’s sociality, David Hesmondalgh’s defense of aesthetic experience, and Martha Nussbaum’s concept of human flourishing. Furthermore, Kertz-Welzel aims to answer the question of what social change is in general but also, concerning music education, to critically consider the contribution that music education can make to social change. She proposes to redefine “the general goals of music education regarding its social and musical intentions, reuniting two dimensions which have been defined as opposite, but are in fact complementary regarding [End Page 99] politically and socially responsive music education and esthetic music education.”2 I will get back later to this last intention in the context of the author’s approach to the redefinition of music education. For now, I will begin with her proposed definition of music education as utopian theory and practice, in the context of the chosen title for this book.Rethinking Music Education and Social Change is a very appealing title not only because rethinking music education is a most pressing issue within the community of music educators but also because social change, in relationship with music, has been the object of research in numerous projects, claiming the transformative power of music. This is a theme I have been very much involved with, being the co-founder of the research platform, Social Impact of Making Music (SIMM),3 that aims to systematically investigate the possible social impacts of learning and playing music. Having said that, I found myself confronted with a book that sets in the middle of its focus to thoroughly investigate the concept of utopia in its multiple facets based on a complete discussion of its theoretical basis. In that context, the fact that the title of the book does not include utopia seemed to me rather puzzling, and I intend to come back to this at the end of this review.The author presents a comprehensive and updated review of the literature, its complexities and ambivalences in the relationship between the arts and social change as it appears and has evolved across time. This approach connects social change with activism, not forgetting the issue of dramatic social change that she exemplifies with the COVID-19 pandemic, and to which we can now sadly add the present state of war. Quoting Roxane de la Sablonniére (2017) and her four typologies of social change, Kertz-Welzel highlights the fact that in the last hundred years the pace of change has increased enormously, and “dramatic social change is a threat to cultural identity.”4The notion of the arts as a political instrument is thoroughly developed, and it should be acknowledged that the author takes here, as well as in other parts of the book, a courageous standpoint. She does not avoid critical or uncomfortable issues, one of them being the ambiguity of the arts. In her discussion on social distinction and identity construction, she cites Max Weber, Georg Simmel, and Pierre Bourdieu and argues that culture has indeed been used as a way of discrimination among people. She also points out the supposedly refined taste of higher social classes cultivated through access to various arts experiences, while others would be denied these experiences and therefore unable to develop their full artistic potential...

Ao analisar parte da tradição filosófica Ocidental e, em particular, contrapor o ensinamento de mestres e gurus do Oriente aos ensinamentos de escolas metafísicas e de ciência política do Ocidente, o presente artigo, poderá ser dito, insere-se na categoria de filosofia das civilizações. Não estando limitada, porém, a nenhuma dessas civilizações, a arte política, enquanto perícia daquele que governa ou leva a vida feliz, pode ser examinada no prolongamento das suas intersecções e enquanto questão filosófica independente. Neste artigo, o autor (...) parte por isso do pressuposto de que a busca do conhecimento do bom governo e vida feliz é comum a ambas as civilizações ou, mais essencialmente, a todo o homem enquanto homem e, observando a ausência de uma correspondência significativa entre ambas no tema da ciência ou arte política, procura examinar possíveis modalidades específicas dessa investigação. Se puder ser dito que, nesse sentido, a filosofia política é uma modalidade mais específica do Ocidente e, do Oriente, a filosofia do sentir intuitivo, o escopo deste artigo é, então, o exame da possibilidade da filosofia do sentir político enquanto questão filosófica independente.

Background: Ethical frameworks for organ donation following circulatory death (DCD) were established >20 years ago. However, considerable variation exists among these, indicating consensus has not been reached on all issues. Additionally, advances such as cardiac DCD transplants and normothermic regional perfusion (NRP) may have reignited old debates.Methods: We reviewed the English-language literature addressing ethical issues in DCD from 1993 to 2022, examining changes in frequency with which ethical principles and their sub-themes identified within each, were addressed.Results: Non-maleficence was the most (...) frequently addressed principle (192 of 199 articles), as well as the most varied, with 9 subthemes (versus 2-4 within each of the other bioethical principles).Conclusions: There were several changes in the terminology used to refer to DCD over time, and substantial interest in cardiac DCD and NRP in recent publications, arising in 11 and 19 of the 30 publications from 2018 to 2022.

In this paper it will be shown that a substantial conception of semantics, one that does not regard semantic phenomena as subsumed under pragmatic ones, is necessary to account for what cries out for an explanation regarding the old problem of the semantic relevance of the referential/attributive distinction, as applied to singular definite descriptions. I consider some alternative proposals to deal with the data, showing why they are wrong, and I finish by establishing that some arguments that allegedly derive the (...) conclusion that some substantial conception of semantics is basically wrong, simply beg the question against their opponents, assuming a form of the very conclusion they want to vindicate.

Harmful but culturally cherished practices often endure in spite of the damages they cause. Meat consumption is increasingly becoming one of such cases and may provide an opportunity from which to observe these phenomena. Growing evidence indicates that current and projected production and consumption patterns are important contributors to significant environmental problems, public health degradation, and animal suffering. Our aim is to contribute to a further understanding of the psychological factors that may hinder or promote personal disposition to change food (...) habits to benefit each of these domains. Drawing from previous evidence, this study explores the proposition that some consumers are motivated to resort to moral disengagement strategies when called upon to consider the impacts of their food habits. Data were collected from six semi-structured focus groups with a sample of 40 participants. Although affirming personal duties towards preserving the environment, promoting public health, and safeguarding animal welfare, participants did not show personal disposition to change their meat consumption habits. Several patterns of response that resonate with the principles of moral disengagement theory were observed while discussing impacts and the possibility of change. Results seem to support the proposition that the process of moral disengagement may play a role in hindering openness to change food habits for the benefit of the environment, public health, and animals, and point towards the relevance of further exploring this approach.

Platelets have important hemostatic functions in repairing blood vessels upon tissue injury. Cytokines, growth factors, and metabolites stored in platelet α‐granules and dense granules are released upon platelet activation and clotting. Emerging evidence indicates that such platelet‐derived signaling factors are instrumental in guiding tissue regeneration. Here, we discuss the important roles of platelet‐secreted signaling factors in skeletal muscle regeneration. Chemokines secreted by platelets in the early phase after injury are needed to recruit neutrophils to injured muscles, and impeding this early (...) step of muscle regeneration exacerbates inflammation at later stages, compromises neo‐angiogenesis and the growth of newly formed myofibers, and reduces post‐injury muscle force production. Platelets also contribute to the recruitment of pro‐regenerative stromal cells from the adipose tissue, and the platelet releasate may also regulate the metabolism and proliferation of muscle satellite cells, which sustain myogenesis. Therefore, harnessing the signaling functions of platelets and the platelet secretome may provide new avenues for promoting skeletal muscle regeneration in health and disease. (shrink)

In this article, we reassess two of Mises’ core methodological claims. The first claim is that action is necessarily rational. The second claim is that all human minds share a logical structure. Neither claim can be unreservedly accepted but, we argue, both contain truth: Mises’ reflections remain important contributions to our understanding of action and the mind, hence to economics.

Charles Darwin's curiosity had a remarkable childlike enthusiasm driven by an almost compulsive appetite for a constant process of discovery, which he never satiated despite his many voyages. He would puzzle about the smallest things, from the wonders of barnacles to the different shapes, colours and textures of the beetles which he obsessively collected, from flowers and stems to birds, music and language, and would dedicate years to understanding the potential significance of everything he saw. Darwin's findings and theories relied (...) heavily on that same curiosity, on seeking and answering questions, however long these would take to clarify. His son Francis Darwin often recalls how "he would ask himself 'now what do you want to say' and his answer written down would often disentangle the confusion". In fact, "disentangling confusions" seems to have been the driving force behind Darwin's scientific pursuits, as he was struck with bewilderment when contemplating the luxuriousness of life. It was also the impetus for this book. The true implications of Darwin's legacy remain as controversial to the critics of our time as they were to his contemporaries. Darwin's impact within and beyond the biological sciences is both daunting and exhilarating, and attests to the need for an interdisciplinary approach by remaining a challenge to many scholars in the most diverse fields. The recent revival of his theories has opened a Pandora's box of different theoretical studies that are particularly receptive to exploring new and exciting angles of research. (shrink)

A Antiguidade não conhecia o conceito de revolução política como irrupção do absolutamente novo. A concepção histórica que foi progressivamente forjada na modernidade considera o curso dos acontecimentos como um processo sem princípio e predeterminados. E no interior desta concepção que pode nascer a idéia de revolução como irrupção do novo na história. O artigo organiza-se em torno das expressões argumenta spes, de F. Bacon, les raisons de notre espérance, de Condorcet, e docta spes, de E. Bloch.

Este estudo objetiva identificar os saberes específicos para o ensino de Língua Portuguesa de professores sem formação específica. Trata-se de uma pesquisa de abordagem qualitativa e biográfica, sendo de cunho exploratório, realizada a partir das histórias de vida. Utilizamos, para produção dos dados, os Ateliês Biográficos de Projetos proposto por Delory-Momberger. O corpus da pesquisa é composto pelas narrativas biográficas construídas nos encontros do ABP e empregamos a análise de conteúdo como técnica para análise dos dados. Assim, evidenciamos que os (...) professores revelaram saberes e não saberes advindos das relações sociais e de sua formação profissional. Constatamos, ainda, a existência de trajetórias marcadas por histórias de vida diferentes, mas que convergem na docência em Língua Portuguesa ; que estes professores aprendem nos caminhos da docência; que mesmo sem terem a formação específica conseguem ensinar. Dessa forma, percebemos os processos formativos a partir da perspectiva pedagógica presente na prática e da revelação de saberes e não saberes para o ensino de Língua Portuguesa, que contribuem para a construção de aprendizagens da docência.

Examinarei aqui dois textos políticos de Sade que propõem um procedimento a ser instituído na elaboração das leis de tal modo que se possa efetivamente fazer da lei a expressão da soberania popular, como queria a constituição republicana francesa de 1793. Os textos em questão são a Adresse au roi des français, de 1791, antes da proclamação da constituição daquele mesmo ano, e Idée sur le mode de la sanction des lois, de novembro de 1792, e que, portanto, precede a (...) constituição republicana de 1793.

Trata-se de examinar os critérios que determinam a legitimidade das manifestações populares no pensamento político de Rousseau. Pode-se dizer que, do ponto de vista do direito, numa república legitimamente constituída, as manifestações do povo são lícitas quando previstas na constituição e formalmente convocadas pelo governo, tanto no caso das reuniões periódicas e ordinárias, quanto das extraordinárias. Em outras palavras: estão excluídas as manifestações espontâneas e as iniciativas populares. Contudo, ao final do primeiro capítulo do livro IV do Contrato, Rousseau se (...) refere ao direito de todo cidadão, que não lhe pode ser tirado, de opinar, de se opor, discutir, propor, direito que os membros do governo querem manter só para si. Pretendo aqui explorar a questão das possibilidades da expressão popular nos livros 3 e 4 do Contrato e nas cartas 7 e 8 das Cartas Escritas da Montanha. (shrink)

Para Diderot, o principio que deve regular a politica é o da continuidade: entre o m aterial , o moral e o político não há ruptura ou mutação. Este princí pio perrnite pensar como tensão paradoxal, e não como contradição insolúv e l, a relaç ã o entre a tendência individual para a felicidade e as exigências da moralidade.

Nos últimos anos o mundo passou a conviver com um processo de expressivas mudanças sociais, culturais e econômicas. O novo século iniciou mitificado como a nova era, em que os avanços são tão acelerados que o futuro se torna, de certa forma, desconhecido. O mundo depara-se com uma nova forma de ver o tempo, o poder, o trabalho, a comunicação, a informação, as instituições e, especialmente, a educação e a função docente, foco da reflexão neste trabalho. A abordagem propõe a (...) constatação das exigências de mudança na atualidade, decorrentes do quadro comple-xo em que se dá a educação escolar hoje para pensar os novos rumos da formação do professor. Em função dessa proposta, são apresentados resultados da investigação desenvolvida considerando as possibilidades de análise abertas por SACRISTÁN. Procurou-se desenlear a função docente da profusão de exigências que lhe são postas na atualidade, numa contribuição ao redirecionamento das propostas prescritivas de mudança e, sobretudo, de formação do professor.

We aim, in the first place, to examine at what extent Holbach´s materialistic monism, as presented in his System of nature (1770), allows us to formulate an original conception of history, so that we can, secondly, ascertain whether this conception of the general course of human events could be identified in his Natural history of superstition.

Trata-se aqui de interpretar algumas passagens do Cândido no quadro das linhas de força do iluminismo francês, que dizem respeito ao modo de conceber a atividade do filósofo, orientado pela oposição entre as figuras do "filósofo de gabinete" e o "filósofo mundano." Do meu ponto de vista, esta oposição não encerra tão somente uma tomada de posição sobre a natureza da ação do filósofo, mas diz respeito mesmo a uma concepção do que é a "boa filosofia." Ao mesmo tempo, permitirá (...) uma interpretação da famosa metáfora do jardim do final do Cândido à luz da concepção voltaireana da história. (shrink)

Voltaire's philosophic tales organize themselves seting out from two reflection poles: on one hand, a discussion about the notion of a benefactor divine providence, and, in some cases, more precisely, about the leibnizian optimism; on the other hand, the controversy around the atheistic materialism. We try to demonstrate through some situations and characters of the voltairean tales how the critique of the providencialist theories contributes to the delineation of the classical materialism's concepts own universe.Os contos filosóficos de Voltaire organizam-se a (...) partir de dois pólos de reflexão: de um lado, a discussão sobre a noção de uma providência divina benfeitora, e, em alguns casos, mais precisamente, sobre o otimismo leibniziano; de outro, a polêmica em torno do materialismo ateu. Procuramos demonstrar de que modo, através de situações e personagens dos contos voltaireanos, a crítica das teorias providencialistas contribui para delinear o universo próprio dos conceitos do materialismo clássico.

Empathy is a major aspect of the interplay between filmmaking and reception. Philosophers and neuroscientists have asserted how film’s technical and conceptual devices seemingly simulate the streamings of consciousness by rendering through images the very processes of thought. More recently, in a noteworthy collaborative work between neuroscience and film theory, Vittorio Gallese and Michele Guerra (2020) have observed how the process of “embodied simulation” is at the basis of empathy, making possible intense and diversified experiences of space, objects and other (...) individuals, and offering an important contribution to the study of how films are experienced and co-created by viewers. Drawing on these arguments from neuroscience, philosophy and film theory, in this paper I explore a renewed relationship between empathy and film aesthetics. (shrink)
