Although it is commonly believed that the concept of brain death was developed to benefit organ transplants, it evolved independently. Transplantation owed its development to advances in surgery and immunosuppressive treatment; BD owed its origin to the development of intensive care. The first autotransplant was achieved in the early 1900s, when studies of increased intracranial pressure causing respiratory arrest with preserved heartbeat were reported. Between 1902 and 1950, the BD concept was supported by the discovery of EEG, Crile’s definition of (...) death, the use of EEG to demonstrate abolition of brain potentials after ischaemia, and Crafoord’s statement that death was due to cessation of blood flow. Transplantation saw the first xenotransplant in humans and the first unsuccessful kidney transplant from a cadaver. In the 1950s, circulatory arrest in coma was identified by angiography, and the death of the nervous system and coma dépassé were described. Murray performed the first successful kidney transplant. In the 1960s, the BD concept and organ transplants were instantly linked when the first kidney transplant using a brain-dead donor was performed; Schwab proposed to use EEG in BD; the Harvard Committee report and the Sydney Declaration appeared; the first successful kidney, lung and pancreas transplants using cadaveric donors were achieved; Barnard performed the first human heart transplant. This historical review demonstrates that the BD concept and organ transplantation arose separately and advanced in parallel, and only began to progress together in the late 1960s. Therefore, the BD concept did not evolve to benefit transplantation. (shrink)

On 5 August 1968, publication of the Harvard Committee’s report on the subject of “irreversible coma” established a standard for diagnosing death on neurological grounds. On the same day, the 22nd World Medical Assembly met in Sydney, Australia, and announced the Declaration of Sydney, a pronouncement on death, which is less often quoted because it was overshadowed by the impact of the Harvard Report. To put those events into present-day perspective, the authors reviewed all papers published on this subject and (...) the World Medical Association web page and documents, and corresponded with Dr A G Romualdez, the son of Dr A Z Romualdez. There was vast neurological expertise among some of the Harvard Committee members, leading to a comprehensible and practical clinical description of the brain death syndrome and the way to diagnose it. This landmark account had a global medical and social impact on the issue of human death, which simultaneously lessened reception of the Declaration of Sydney. Nonetheless, the Declaration of Sydney faced the main conceptual and philosophical issues on human death in a bold and forthright manner. This statement differentiated the meaning of death at the cellular and tissue levels from the death of the person. This was a pioneering view on the discussion of human death, published as early as in 1968, that should be recognised by current and future generations. (shrink)

Populist representation is the process by which a body or set of bodies become the signifier of a powerful act of political transgression of the social order. We call this specific type of representative linkage ‘synecdochal representation’. In it, the leader’s body performs three key functions: it mirrors certain popular traits that are characterized as ‘low’, it displays marks of exceptionality, and it appropriates symbols of institutional power. These tasks are performed through particular ways of acting, dressing, talking, eating, and (...) the like, in public. Social media has become a key locus for bodily self-presentation because it is used to create the appearance of intimacy and spontaneity through the distribution of ‘candid’ pictures and videos. This paper will analyze how the self-presentation of populist and non-populist leaders are established through Twitter, what images they choose to disseminate, and how they are re-signified by the audience. To do so, we will focus on the two Latin American politicians: Cristina Fernández (with a populist style) and Mauricio Macri (with a technocratic one). (shrink)

Resumo No Manifesto surrealista, de 1924, Breton explicita o produto da atividade surrealista como uma “luz de imagem”, gerado pela aproximação involuntária de duas realidades distantes. Essa estrutura dupla da imagem surrealista tem um caráter disruptivo, que rompe com a nossa percepção da realidade cotidiana. Com isso, abre-se a possibilidade de um espaço para a crítica social e histórica, bem como para uma intervenção estético-política justamente em uma sociedade na qual as formas tradicionais de crítica parecem estar neutralizadas. Essa experiência (...) surrealista e esse espaço aberto por ela Walter Benjamin caracteriza respectivamente com a fórmula “iluminação profana” e “espaço de imagem”. Ambos apresentam uma grande semelhança com alguns pontos e consequências, em seus conceitos, tanto de “imagem do pensamento”, como de “imagem dialética”, sobretudo na medida em que esses conceitos também são formulados em meio à crise cultural da sociedade europeia, nos 1920, e buscam uma saída revolucionária para a mesma. Trata-se de investigar aqui, por meio de uma análise comparativa dessas concepções de imagem, até onde vai a influência e a relevância do surrealismo para o pensamento figurativo-dialético de Benjamin e para sua compreensão da história.In the Surrealistic manifest from 1924, Andre Breton explains the product of surrealistic action as a “light of image” resulting from an arbitrary approach of two distant realities. This double structure of surrealistic image has a disrupting character that breaks our common perception of reality. Thus can open a space for social and historical criticism as well as for an aesthetical-political intervention in a society where traditional forms of criticism seem to be neutralized. Walter Benjamin defines this surrealistic experience and its opened space respectively with the expressions “profane illumination” and “image space”. Both have similarities with Benjamin’s ideas of “thought image” and “dialectical image”, especially because they were elaborated amidst the cultural european crisis in the 1920ies looking to find a revolutionary way out of it. Through a comparative analysis of these notions of image, this paper proposes to investigate the influence and the relevance of surrealism for Benjamin’s dialectical-figural way of thinking and his comprehension of history.

There is growing worldwide concern that the rampant spread of digital fake news via new media technologies is detrimentally impacting Democratic elections. However, the actual influence of this recent Internet phenomenon on electoral decisions has not been directly examined. Accordingly, this study tested the effects of attention to DFN on readers’ Presidential candidate preferences via an experimental web-survey administered to a cross-sectional American sample. Results showed no main effect of exposure to DFN on participants’ candidate evaluations or vote choice. However, (...) the perceived believability of DFN about the Democratic candidate negatively mediated evaluations of that candidate—especially amongst far-right ideologues. These results suggest that DFN may at worst reinforce the partisan dispositions of mostly politically conservative Internet users, but does not cause or induce conversions in these dispositions. Overall, this study contributes novel experimental evidence, indicating that the potential electoral impact of DFN, although concerning, is strongly conditional on a reciprocal interaction between message receptibility and a pre-existing right-wing ideological orientation. The said impact is, therefore, likely narrow in scope. (shrink)

Dentro da relação entre a necessidade humana de compreensão e os “murros fechados do mundo” que o absurdo camusiano ocorre. O absurdo, vindo dessa dicotomia entre ser humano e mundo, decorrente dessa impossibilidade, ou com maior precisão, da irracionalidade do mundo descoberto pelo ser humano, é o que pauta a filosofia de Camus. Nesse contexto, a relação do absurdo com a ciência se torna um tema central de um dos ensaios de Camus, O mito de Sísifo. O autor expressa toda (...) sua revolta com a ciência moderna por nunca lhe oferecer o mundo, a ciência apenas descreve e elucida, nunca fornece o mundo à compreensão do ser humano. Essa situação pode ser esclarecidase atendo aos livros de alguns cientistas do século XX, principalmente Werner Heisenberg, o qual elucida, em A parte e o Todo, uma discussão ao redor do tema da compreensão na física moderna. Sendo assim, o propósito deste artigo é estabelecer uma relação entre o absurdo e a revolta de Camus com a ciência com o que Heisenberg demostra como os limites da compreensão na física. No final, parece que ambos autores convergem a conclusão de que o ser humano não é capaz de chegar a compreensão do mundo por meio da ciência. (shrink)

Disconcerting findings from nascent sociological research suggest that Western youth are developing subjectivities that reflect neoliberal discursive formations of self-interest, competitiveness, and materialism. However, propositions about: (1) the cognitive-affective mechanisms that explain how youth acquire and reproduce neoliberal ideology, or (2) the dispositions and behaviours that typify a neoliberal subject, remain vague. Therefore, this article provides a novel conceptualization of these two psychosocial facets that can help advance understandings and investigations of the emerging modes and societal consequences of neoliberal subjectification, (...) Specifically, it reviews major theoretical tenets from the respective literatures on neurocognitive development, social cognition, neoliberalism, and neoliberal hegemony. It then synthesizes these tenets within a modified habitus formulation to sketch a testable cognitive-sociological model to explain and explore some of the distinct dispositional values, attitudes, and practices that youth raised in societies with institutionally and culturally prevalent neoliberal norms and discourses potentially may develop and enact.

O presente artigo desenvolve um diálogo entre a teoria de gênero e a literatura feminina. Para tanto, utiliza-se a _Tetralogia napolitana_, obra da autora italiana Elena Ferrante, como objeto de análise. Busca-se fazer uma relação entre a vida privada das personagens e seus dilemas com casamento, família, maternidade, trabalho e de teorias a respeito da divisão sexual do trabalho, da dominação masculina e do cuidado. Trata-se de uma pesquisa qualitativa de tipo exploratório, levando como base de análise o material bibliográfico (...) e documental referentes ao problema em questão. Verifica-se como a divisão sexual do trabalho, a dominação masculina e a ética do cuidado estabeleceram condições desfavoráveis para as personagens ao longo de suas vidas. Concluindo que o campo literário é um cenário importante para estudos relacionados às temáticas de gênero e feminismo, seja por sua demonstração detalhada do cotidiano feminino, seja pela escrita feminina.

La física durante la segunda mitad del siglo XIX experimentó una silenciosa pero profunda revisión de sus fundamentos. A pesar de su importancia para los desarrollos posteriores de la física, los estudios históricos y filosóficos sobre dicho periodo son escasos comparados con aquellos de principios del siglo XX. Este trabajo reconstruye algunos aspectos de la física de este periodo usando dos herramientas conceptuales: espacios controversiales de Oscar Nudler y estilo de razonamiento científico de Ian Hacking. El objetivo es mostrar los (...) elementos que produjeron el desbloqueo conceptual de la controversia sobre el determinismo durante la segunda mitad del siglo XIX y principios del siglo XX. (shrink)

En este trabajo realizo un examen crítico del reciente libro de Silvana Gabriela Di Camillo sobre la crítica de Aristóteles a la teoría platónica de las Ideas. El libro de Di Camillo es un trabajo muy serio cuya lectura recomiendo ampliamente. Sin embargo, considero que cuatro de las principales tesis que la autora defiende tienen varias dificultades y mi objetivo aquí es presentar argumentos detallados en contra de ellas: la interpretación de la distinción entre argumentos más y menos rigurosos del (...) tratado Sobre las Ideas; la tesis de que la separación es el blanco esencial de las críticas aristotélicas a las Ideas; la interpretación de las opciones que Platón tiene para responder al argumento del tercer hombre, y la tesis de que la separación de las Ideas debe entenderse como homonimia. In this paper I examine Silvana Gabriela Di Camillo's recent book on Aristotle's criticisms of Plato's theory of Ideas. Di Camillo's book is a very serious work that I highly recommend. Nevertheless, I consider that four of the main theses that the author defends face several difficulties and my aim here is to offer detailed arguments against them: the interpretation of the distinction between more and less accurate arguments of the treatise On Ideas; the thesis that separation is the essential target of Aristotle's criticisms against Plato's Ideas; the interpretation of the options available to Plato to reply to the third man argument; and the thesis that the separation of Ideas should be understood as homonymy.

Kerridge et al recently published a paper in the journal about organ transplantation and the diagnosis of death.1 Although I appreciate the authors’ efforts to present their arguments about such a controversial issue, I found some inconsistencies in this article that I would like to discussWhen Kerridge and his collaborators discussed the origins of the concept of brain death , they emphasised that after the report of the medical consultants on the diagnosis of death to the US President’s Commission was (...) published in 1981,2 clinicians equated the concept of BD with brainstem death. In fact, the brainstem criterion was first proposed by Mohandas and Chou in Minnesota, in 1971.3 The Minnesota criteria inspired the UK code, which was mainly adopted in UK commonwealth countries.4 This view was afterwards powerfully defended by Christopher Pallis.5 After the US President’s Commission report,2 a lot of countries, and most US states, accepted the whole brain, and not the brainstem, criterion.6Regarding the “dead donor rule”, with the advent of transplant surgery, interest in definitions and diagnosis of death based on brain formulations really acquired a new urgency. None the less, it is important to point out that the concept of BD as death of the individual, did not appear to benefit organ transplantation, but was a consequence of the development of intensive care. As Pallis emphasised, if organ transplant techniques had never been developed, intensive care procedures would have provided the possibility of supplying life support to those cases with destroyed brains and preserved heart function, and physicians would need to face the clinical syndrome called BD.5 When French neurophysiologists and neurologists described the death of the nervous system and coma dépassé, organ transplant techniques were only in the very early stages of development. ….

Happy the elephant is intelligent, social, and self-aware--and considered a thing in the eye of the law. Led by lawyer Steven M. Wise, the Nonhuman Rights Project has filed cases on behalf of captive nonhuman animals like Happy since 2013, arguing that their autonomy entitles them to certain legal rights. In Thing: Inside the Struggle for Animal Personhood, comic artists Sam Machado and Cynthia Sousa Machado bring together Wise's groundbreaking work and their own illustrations in the first graphic (...) nonfiction book about the animal personhood movement. Beginning with Happy's story and the central ideas behind animal rights, Thing then turns to the scientists that are revolutionizing our understanding of the minds of such nonhuman animals as great apes, elephants, dolphins, and whales. Combining legal and social history, innovative science, and illustrated storytelling, Thing presents a visionary new way of relating to the nonhuman world. (shrink)

This study situates Henry Havelock Ellis’s sexological research within the nineteenth-century evolutionary debates, especially the discussion over sexual selection’s applicability to humanity. For example, Ellis’s monograph on sexual behavior, _Sexual Inversion_ (1897), treated inborn homosexuality as a natural variation of evolutionary mechanisms. This book was situated within a longer study of human sexuality in relation to evolutionary selection. His later works dealt even more directly with Charles Darwin’s concept of selection, such as _Sexual Selection in Man_ (1905). Through _Sexual Selection (...) in Man_, Ellis asserted that sexual attraction stemmed from a physical cause rather than an innate aesthetic sense. I argue that Ellis’s best-known historical publications, including his work on sexual inversion, were intended to intervene in the contemporary evolutionary debates. This analysis also identifies a specific point where evolutionary theory informed the foundation of sexology as a scientific discipline. (shrink)

The perspectives of Inclusive Education in the Education course: narratives of beginning teachers Abstract: This study aims to analyze the perspectives of future teachers in relation to the pedagogical practices necessary for the inclusion of students with disabilities, as well as the possibility of building them in the school routine. In order to participate in the research, sixteen future teachers who are attending the last semesters of the Education course and already work as interns in Basic Education were selected. The research is based on a qualitative approach and it uses narratives as an instrument for data collection. From the discursive textual analysis process, three dimensions were identified, based on the themes used in this study: Inclusive Education; Inclusive Pedagogical Practices; Experience. The results of the study indicate the experiences of the teachers as new and significant, and that the main element for the transformation of inclusive education involves the need for training, studies and exchanges of experiences as well as constant theoretical-practical construction, which is essential in the inclusive process.

Vir a ser cidadão: Educação, Política e Psicologia do Desenvolvimento Resumo: Considerando a tese honnethiana de que, hodiernamente, há um desenlace entre Educação e Política, e afirmando um forte nexo entre essas áreas no pensamento de Jean-Jacques Rousseau, neste trabalho, apresentamos alguns aspectos de como, para este, é possível que o ser humano, como membro da espécie, venha a ser cidadão. Em seguida, contando com a crítica de Nussbaum sobre como muitas propostas educacionais não explicitam uma psicologia do desenvolvimento, aventamos (...) uma vinculação entre Educação, Política e ideias psicológicas em Rousseau. Adiante, trazemos elementos da pesquisa psicogenética de Jean Piaget, propondo que esse tipo de pesquisa permite um fortalecimento do nexo entre as áreas da Educação, Política e, agora, Psicologia do Desenvolvimento, contribuindo para a discussão ainda atual acerca do vir a ser cidadão.

Becoming a citizen: Education, Politics and Developmental Psychology Abstract: Considering the Honnethian thesis that there is today a disconnexion between Education and Politics, and asserting a strong link between these fields in the thought of Jean-Jacques Rousseau, in this work we present some aspects of how, for him, it is possible for a human, as a member of the species, to become a citizen. Then, relying on Nussbaum's critique of the fact that many educational proposals do not make developmental psychology explicit, we suggest a link between Education, Politics and psychological ideas in Rousseau. Ahead, we bring elements of Jean Piaget's psychogenetic research, proposing that this type of research allows a strengthening of the nexus between the fields of Education, Politics and, now, Developmental Psychology, contributing to the still current discussion about becoming a citizen.

Originally published in Mexico in 1970, _Indigenous and Popular Thinking in América _is the first book by the Argentine philosopher Rodolfo Kusch to be translated into English. At its core is a binary created by colonization and the devaluation of indigenous practices and cosmologies: an opposition between the technologies and rationalities of European modernity and the popular mode of thinking, which is deeply tied to Indian ways of knowing and being. Arguing that this binary cuts through América, Kusch seeks (...) to identify and recover the indigenous and popular way of thinking, which he contends is dismissed or misunderstood by many urban Argentines, including leftist intellectuals. _Indigenous and Popular Thinking in América_ is a record of Kusch's attempt to immerse himself in the indigenous ways of knowing and being. At first glance, his methodology resembles ethnography. He speaks with and observes indigenous people and mestizos in Peru, Bolivia, and Argentina. He questions them about their agricultural practices and economic decisions; he observes rituals; he asks women in the market the meaning of indigenous talismans; he interviews shamans; he describes the spatial arrangement and the contents of shrines, altars, and temples; and he reproduces diagrams of archaeological sites, which he then interprets at length. Yet he does not present a "them" to a putative "us." Instead, he offers an inroad to a way of thinking and being that does not follow the logic or fit into the categories of Western social science and philosophy. In his introduction, Walter D. Mignolo discusses Kusch's work and its relation to that of other twentieth-century intellectuals, Argentine history, and contemporary scholarship on the subaltern and decoloniality. (shrink)

Resumen En este trabajo evaluamos el impacto que la adopción de la relatividad del movimiento tiene en la metafísica de Leibniz. En particular argumentamos que el abandono de la comprensión absolutista del mismo anula su noción juvenil de sustancia corpórea. En primer lugar analizamos cómo entiende Leibniz las nociones de cuerpo y movimiento en el periodo juvenil y defendemos que la comprensión absolutista de este último constituye una piedra angular en su primera concepción de la sustancia corpórea. En segundo lugar (...) exponemos los argumentos leibnizianos a favor de la relatividad del movimiento durante el período parisino y mostramos su repercusión en el concepto juvenil de sustancia corpórea.In this paper we evaluate the impact of Leibniz's defense of relativity of motion on his metaphysics. We argue that the abandonment of the absolutist position makes void his first notion of corporeal substance. First, we analyze Leibniz's conception of body and movement in his youth and explain how the assumption of absolute motion during these years plays a role in his notion of corporeal substance. Second, we examine his arguments in favor of relativity of motion during the Parisian period and show the repercussion on his first conception of the corporeal substance. (shrink)

The mortality rate of patients affected with oral squamous cell carcinoma has been stable in recent decades due to several factors, especially diagnostic delay, which is often associated with a late stage diagnosis and poor prognosis. The aims of this paper were to: analyze diagnostic delay in OSCC and to discuss the various psychological factors of patients with OSCC, with particular attention to the patient’s fear of receiving news regarding their health; and the professional dynamics related to the decision-making processes (...) in cases of suspected OSCC. A preliminary review of literature focusing on OSCC diagnostic delay was performed. Seven articles were included with the diagnostic delay ranging from 45 days to approximately 6 months. Patients’ fears and, to a lesser degree, the concerns of dentists, were found to be still poorly investigated. On the basis of the authors’ professional experience, the development of oral lesions of unknown origin may generate different behaviors in the decision-making processes by patients and clinicians, and fear may play a key role in the distinct steps of this process. It is crucial to increase awareness and inform patients about the onset of OSCC, and contemporaneously encourage experimental studies on patients’ fear and professional behaviors with respect to communication regarding OSCC.

En el trabajo evaluamos el impacto que la crítica de Leibniz a los números infinitos tiene en el desarrollo de su metafísica de los cuerpos. Luego de exponer el vínculo que el filósofo alemán traza entre el cuerpo, la extensión y las cantidades infinitas en su período juvenil (1663-1672), analizamos sus reflexiones del período parisino sobre las paradojas de los números infinitos (1672-1676) y argumentamos que la defensa de la inconsistencia de tales números constituye un punto de inflexión en su (...) comprension de los cuerpos y, asimismo, marca el inicio de su ofensiva contra la res extensa.In this paper we study the impact of Leibniz’s critique of infinite numbers in his metaphysics of bodies. After presenting the relation that the German philosopher establishes in his youth between the notions of body, extension and infinite quantities (1672-1673), we analyze his thoughts on the paradoxes of the infinite numbers (1672-1676) and we claim that his defense of the inconsistency of such numbers is an inflexion point in his conception of body and mark the beginning of his offensive against the res extensa.

We argue that it is fundamentally impossible to recover information about quantum superpositions when a quantum system has interacted with a sufficiently large number of degrees of freedom of the environment. This is due to the fact that gravity imposes fundamental limitations on how accurate measurements can be. This leads to the notion of undecidability: there is no way to tell, due to fundamental limitations, if a quantum system evolved unitarily or suffered wavefunction collapse. This in turn provides a solution (...) to the problem of outcomes in quantum measurement by providing a sharp criterion for defining when an event has taken place. We analyze in detail in examples two situations in which in principle one could recover information about quantum coherence: a) “revivals” of coherence in the interaction of a system with the measurement apparatus and the environment and b) the measurement of global observables of the system plus apparatus plus environment. We show in the examples that the fundamental limitations due to gravity and quantum mechanics in measurement prevent both revivals from occurring and the measurement of global observables. It can therefore be argued that the emerging picture provides a complete resolution to the measurement problem in quantum mechanics. (shrink)
