Após a conclusão do curso de medicina psiquiátrica em Lyon, em 1951, Fanon foi acolhido no hospital Saint Alban, para um aprofundamento dos estudos psiquiátricos, tendo ali, trabalhado e pesquisado sob a supervisão do psiquiatra espanhol Francesc Tosquelles, onde praticou os fundamentos da psicoterapia institucional, desenvolvida por Tosquelles e seus colaboradores naquele hospital. Mais tarde, na Argélia, Fanon atuou no hospital de Blida-Joinvile e, posteriormente, na Tunísia, introduzindo reformas, à luz da psicoterapia institucional. A concepção de ser humano que cultivava (...) e a compreensão de que a sociedade doente produz pessoas doentes, levaram-no a um profundo conflito, à medida em que foi tomando consciência da violência do colonialismo francês contra o povo argelino, conforme relatou na carta de demissão que enviou ao Ministro Residente, Robert Lacoste, em 1956. Após o pedido de demissão, adentrou o movimento de libertação da Argélia. Escreveu livros e artigos combatendo o colonialismo e difundindo os ideais revolucionários. Van Renssalaer Potter, por longo tempo atuou como biólogo e bioquímico no MacArdle Laboratory for Cancer Research, na Universidade de Winsconsin, na cidade de Madison, onde doentes de câncer eram tratados. Na década de 1970, publicou um livro seminal, Bioética, ponte para o futuro. Anos depois, publicou estudos de Bioética Global. Mais tarde, articulou conceitos de Bioética Profunda. Preocupado com a sobrevivência humana neste planeta, atacado pela irresponsabilidade humana, Potter conclamou a humanidade à tomada de consciência e mudança de condutas. Comparando-se os dois autores, observa-se que os escritos de Fanon foram produzidos na década de 1950, sendo que seu último livro, Os Condenados da Terra, foi escrito em 1961. Potter, por sua vez, escreveu os primeiros estudos de bioética na década de 1970, cerca de uma década após o falecimento de Fanon. Respeitados os limites cronológicos, este estudo se pergunta: A dialética da medicina como política e da política como medicina, na práxis de Fanon, teria sintonias bioéticas? Para enfrentar este problema, o trabalho contextualiza a formação de Fanon, identificando os princípios da práxis médico-psiquiátrica dele. Em seguida, demonstra-se as contradições do colonialismo, identificando uma dialética da medicina como política e da política como medicina. Adiante, informa-se a contribuição de Van Rensselaer Potter, na proposição da bioética. Finalmente, argumenta-se a favor das sintonias bioéticas presentes nas passagens selecionadas. O procedimento metodológico é a pesquisa bibliográfica, analítico-dedutiva. Palavras-chave: Colonialismo. Consciência. Medicina. Política. Sintonias bioéticas. (shrink)

Resumo: As grandes corporações de comunicação, no Brasil, operam como construtoras de sentidos, por meio de narrativas sintonizadas com os interesses de grupos e atores sociais, com desprezo para as demandas e os direitos dos setores populares. Uma prática semelhante de comunicação foi vivenciada por Frantz Fanon, na África. No entanto, o ativista conseguiu fazer da sua práxis jornalística um instrumento a serviço da justiça e da libertação de povos africanos oprimidos. Essa prática libertária de Fanon identifica-se com os ideais (...) da bioética global, criada posteriormente por Van Rensselaer Potter. Frente a esse cenário, esta reflexão quer investigar em que sentido a práxis jornalística de Fanon, durante a guerra de libertação argelina, em busca de justiça social e de libertação, se identifica com os fundamentos da bioética global proposta posteriormente por Potter. A análise consiste numa argumentação de caráter analítico-dedutivo. Se, com a bioética global, Potter procurou restaurar um sentido humano da práxis científica e tecnológica, Fanon buscou esse objetivo como comunicador social e médico.: The big communication corporations of Brazil operate as constructers of meaning trough syntonized narratives in behalf of groups and social players, and with contempt for the rights and demands of popular sectors. A similar communication practice was experienced by Frantz Fanon in Africa. However, the activist was able to make an instrument in service of justice and liberation of oppressed African people from his journalistic practice. This libertarian practice of Fanon identifies oneself with the subsequently created global bioethics of Van Rensselaer Potter. In the face of this scenario, this reflection wants to investigate in what sense the journalistc praxis of Fanon during the Argelian Revolution, in pursuit of social justice and liberation, identifies itself with the global bioethics principles later proposed by Potter? The analyses consists in an anaclitic deductive character. If with global bioethci Potter searched to restore a human sense of the technological and scientific praxis, Fanon seeked this goal as an social communicator and physician. (shrink)

Since the end of the 19th century, Brazilian researchers have speculated about the phenomenon of ethnic coexistence they have witnessed in their country. How may the mixed culture that is its obvious result be explained? Should it be attributed to some sociocultural syncretism, to an interpenetration of civilizations or, quite simply, to a synthesis? Whatever the case, it is certain that cultural elements of very different origins became united in Brazil and that they have remained closely associated there in spite (...) of their disparity. The best example of this “cultural conglomerate,” if we may call it that, is without a doubt that of the Afro-Brazilian religious cults and, although numerous studies have already been devoted to them, they have a richness of content and meaning, plus a capacity for renewal, that is far from being exhaustively investigated.

Rio de Janeiro, the opening of the carnival. On the Friday evening preceding Mardi Gras, the mayor of Rio hands over the keys to the city to King Momo, sovereign of the carnival. Immediately the samba breaks out in the brightly lit streets of the city. Newspapers, magazines and television feature big headlines describing the event and glorifying the holiday kingdom.

Carnival was brought to the New World by Spanish and Portuguese colonizers, and it has been preserved there up to our day, although in the meantime it has almost disappeared from the countries where it originated. One asks oneself if Carnival has kept its original characteristics over the years, or if it instead has been transformed, and if so, how. The ethnological and cultural variety present in Latin America leads us to think that there must have been an evolution over (...) the years, and that Carnival should show some signs of acculturation. It is the examination of these two points that will be the subject of our study. (shrink)

Introduction: The importance attached to ethical practice and related informed consent varies among health professionals and is further influenced by working environments, level of knowledge, experience and societal values and beliefs. The objective of this study is to evaluate the ethical conduct of professors, undergraduates and graduate students through questionnaires answered by patients. Methods: One hundred twenty patients at the dental clinics of three different dental schools in São Paulo State were interviewed based on objective and discursive questions about signed (...) informed consent, participation in scientific research, photographs during treatment, requested saliva samples, tooth donation requests, and information about tooth destination after removal. A frequency distribution was used for a statistical analysis of the data. Results: In all, 65.8% of the patients had given signed informed consent for treatment and 12.5% had not done so; 10.8% did not know if they had participated in scientific research; 54.2% were photographed during dental procedures and 47.1% of them had signed an authorization form; 6.6% were requested to provide a saliva sample and 66.6% of them had signed an authorization form to that effect; 16.1% had a tooth donation requested and 64.4% of them had signed an authorization form to that effect; and 61.3% did not know the destination of the tooth after removal, when donation was not requested. Conclusions: The majority of the patients had signed an informed consent form for treatment, photographs, saliva samples and tooth donation. This demonstrated ethical conduct towards patients on the part of professors, undergraduates and graduate students. doi: 10.5294/pebi.2017.21.1.2. (shrink)

A presente proposta busca sistematizar a importância da valorização do docente através do período extraclasse, prevista pela Lei do Piso Salarial Profissional Nacional docente (PSPN), observando a proposta de formação continuada, e, também, formação permanente, desenvolvida no Centro de Formação Carolina Garcia (CFCG), localizado no município de Macaé/RJ. A discussão aprofundada por meio da monografia de pedagogia da extinta Faculdade de Filosofia, Ciências e Letras de Macaé – FAFIMA, tem como base os relatos apresentados nos questionários semiestruturados respondido pelas coordenadoras (...) do local, no ano de 2019. Nesse sentido, buscamos perceber o processo de elaboração da proposta do CFCG, que marca todo um movimento de formação pioneira em diálogo com o PSPN. Concluímos ao longo da pesquisa, que existem várias experiências que priorizam o fazer docente em diálogo com o período extraclasse, mas historicamente o CFCG propõe a ampliação do conhecimento de dentro da profissão e do seu entorno.

The geometric system of deduction called N-Graphs was introduced by de Oliveira in 2001. The proofs in this system are represented by means of digraphs and, while its derivations are mostly based on Gentzen's sequent calculus, the system gets its inspiration from geometrically based systems, such as the Kneales' tables of development, Statman's proofs-as-graphs, Buss' logical flow graphs, and Girard's proof-nets. Given that all these geometric systems appeal to the classical symmetry between premises and conclusions, providing an intuitionistic version of (...) any of these is an interesting exercise in extending the range of applicability of the geometric system in question. In this article we produce an intuitionistic version of N-Graphs, based on Maehara's LJ' system, as described by Takeuti. Recall that LJ' has multiple conclusions in all but the essential intuitionistic rules, e.g., implication right and negation right. We show soundness and completeness of our intuitionistic N-Graphs with respect to LJ'. We also discuss how we expect to extend this work to a version of N-Graphs corresponding to the intuitionistic logic system FIL (Full Intuitionistic Logic) of de Paiva and Pereira and sketch future developments.

Este ensaio celebra as cinco décadas da publicação do livro A ordem do discurso de Michel Foucault, realizando uma reflexão acerca de sua repercussão entre as ciências sociais e sobre seus usos, principalmente, no campo da linguagem na parte relacionada à análise do discurso de linha francesa. Portanto, trata-se de uma retrospectiva crítica cuja análise começa com a entrevista que Foucault concedeu algumas semanas antes de proferir esta aula aos brasileiros Sergio Paulo Rouanet e José Guilherme Merquior. Em seguida, o (...) presente trabalho faz uma breve história da entrada de Foucault ao Collège de France e, por fim, lida com a microfísica do discurso que se encontra nesta aula, sobretudo, da rarefação do sujeito, além dos seus usos nas ciências humanas e sociais mais o campo da linguagem em torno da pragmática e das análises de discurso.

Este estudio se ocupa del control social del cuerpo y de la reconfiguración de la memoria popular en películas de horror a través de la perspectiva genealógica de Foucault, presentada en su libro Vigilar y Castigar, publicado hace 40 años. Por lo tanto, tomaremos, À l’interieur e Frontière (s), dos producciones de horror cinematográfico hechas por directores franceses, ambos publicados en 2007. La hipótesis principal es que las películas de terror se muestran como una nueva forma de vigilancia y control (...) social del cuerpo. Por otro lado, también puede recodificar la memoria popular apropiándose de acontecimientos polítcos y/o revolucionarios como en las películas comentadas por Foucault en la revista Cahiers de Cinéma en 1974 políticas, aunque no sean las películas de terror.

Este trabalho trata do conceito Exu Diaspórico, o qual foi forjado para lidar com as pesquisas empíricas situadas dentro do quadro teórico da vaga decolonial. Sua concepção está ligada às tradições iorubanas diaspóricas nessa parte do Atlântico Sul onde emergiram outros sistemas resultantes, quer seja de fragmentos e vestígios de narrativas em gestos de memória e resistência, quer seja da tradução realizada pelo outro, muitas vezes, por meio de um processo de carnavalização cultural, que, por sua vez, se deu pela (...) convivência com os bantu, com os povos autóctones e com o colonizador europeu. Este conceito se articula com o conceito de língua-linguagem como encruzilhada apresentado por Araújo (2021a), mas pode ser tomado, ainda, de forma independente. Portanto, trata-se de uma discussão conceitual que visa contribuir com as reflexões e pesquisas decoloniais. O conceito também está a cargo de noções como negritude e Baianidade. Contudo, ele aparece para reunir todas as representações de Exu que resultaram da diáspora negra em meio a um processo de carnavalização das tradições iorubanas em contato com outras culturas e cosmologias.

O presente trabalho tem o objetivo de conectar a teoria criada por Pierre Bourdieu sobre a violência simbólica e o texto de Audre Lorde, The use of anger: women responding to racism do seu livro Sister Outsider; demonstrando a importância do debate sobre a relação entre dominante e dominado a partir do viés racial, tema abordado por ambos autores em seus textos. Com este fito, pretendemos diferenciar os resultados objetivos do ódio, raiva e culpa, bem como o modo que as (...) agressões invisíveis repercutem na vida do oprimido. Tendo como foco o racismo na vida da “mulher de cor” que ainda nos dias de hoje, em uma pirâmide social, se encontram em desvantagem quanto aos demais indivíduos. Faz parte dos objetivos também trazer à tona a reação do oprimido como consequência natural dos séculos de silenciamento, privação e desumanização, analisando os mecanismos institucionais para pacificação social.

Taxonomies of living things and the methods used to produce them changed little with the institutionalization of evolutionary thinking in biology. Instead, the relationships expressed in existing taxonomies were merely reinterpreted as the result of evolution, and evolutionary concepts were developed to justify existing methods. I argue that the delay of the Darwinian Revolution in biological taxonomy has resulted partly from a failure to distinguish between two fundamentally different ways of ordering identified by Griffiths : classification and systematization. Classification consists (...) of ordering entities into classes, groups defined by the attributes of their members; in contrast, systematization consists of ordering entities into systems, more inclusive entities whose existence depends on some natural process through which their parts are related. Evolutionary, or phylogenetic, systematics takes evolutionary descent to be the natural process of interest in biological taxonomy. I outline a general framework for a truly phylogenetic systematics and examine some of its consequences. (shrink)

An examination of the post-Darwinian history of biological taxonomy reveals an implicit assumption that the definitions of taxon names consist of lists of organismal traits. That assumption represents a failure to grant the concept of evolution a central role in taxonomy, and it causes conflicts between traditional methods of defining taxon names and evolutionary concepts of taxa. Phylogenetic definitions of taxon names (de Queiroz and Gauthier 1990) grant the concept of common ancestry a central role in the definitions of (...) taxon names and thus constitute an important step in the development of phylogenetic taxonomy. By treating phylogenetic relationships rather than organismal traits as necessary and sufficient properties, phylogenetic definitions remove conflicts between the definitions of taxon names and evolutionary concepts of taxa. The general method of definition represented by phylogenetic definitions of clade names can be applied to the names of other kinds of composite wholes, including populations and biological species. That the names of individuals (composite wholes) can be defined in terms of necessary and sufficient properties provides the foundation for a synthesis of seemingly incompatible positions held by contemporary individualists and essentialists concerning the nature of taxa and the definitions of taxon names.

At least three different issues are commonly referred to by the term “the species problem”: one concerns the necessary properties of species, a second the processes responsible for the existence of species, and a third methods for inferring species limits. Solutions have recently been proposed to the first two problems, which are conceptual in nature (the third is methodological). The first equates species with metapopulation lineages and proposes that existence as a separately evolving metapopulation lineage be considered the only necessary (...) property of species. The second views the species category as a cluster concept and proposes that no single process or set of processes be considered necessary for the existence of species. Although these two solutions have been portrayed as being in conflict, they are, in fact, highly compatible. Moreover, the proposals in question clarify the problem concerning methods for inferring the limits of species, which has for a long time been confused with the problem concerning the necessary properties of species. Together these proposals provide the opportunity for biology to move beyond debates about the definition of the species category and focus on estimating the boundaries and numbers of species as well as studying the diverse processes involved in their origin and persistence.

SummaryLooking at proof theory as an attempt to ‘code’ the general pattern of the logical steps of a mathematical proof, the question of what kind of rules can make the meaning of a logical connective completely explicit does not seem to have been answered satisfactorily. The lambda calculus seems to have been more coherent simply because the use of ‘λ’ together with its projection 'apply' is specified by what can be called a 'reduction' rule: β‐conversion. We attempt to analyse the (...) role of proof rules, making use of a set of formal rules designed to capture both the notions of proof theory and those of the lambda‐calculus: Martin‐Löf's Intuitionistic Type Theory.RésuméSi on considère la théorie de la démonstration comme une tentative de ‘codifier’ les pas logiques d'une démonstration mathématique, on se rendra compte qu'on n'a pas répondu de façon satisfaisante à la question suivante: quelles sont les règies qui rendent complètement explicite le sens d'un connecteur logique? Le lambda‐calcul a été apparemment plus cohérent, tout simplement parce que l'utilisation du‘λ’ avec sa projection 'apply' est spécifiée par une regie de 'réduction': β‐conversion. Nous essayons d'analyser le rôle des règies de démonstration, en utilisant un système formel de règies conçu pour englober à la fois les notions de la théorie de la démonstration et celles du lambda‐calcul: la Théorie Intuitionniste des Types de Martin‐Löf.ZusammenfassungWenn man Beweistheorie als einen Versuch, ein allgemeines Muster der logischen Schritte in einem mathematischen Beweis zu kodifizieren, betrachtet, so scheint die Frage nach der Art von Regeln , die die Bedeutung von logischen Operatoren vollständig beschreiben, nicht zufriedenstellend beantwortet. Der Lambda‐Kalkül erscheint, kohärenter, einfach deshalb weil der Gebrauch von ‘λ’ zusammen mit dessen Projektion 'apply' durch Regeln bestimmt wird, die man 'Reduktions'‐Regeln nennen kann: β‐Konversion. Wir versuchen, die Rolle von Beweisregeln zu analysieren, indem wir ein Regelsystem verwenden, das sowohl die Begriffe der Beweistheorie als auch diejenigen des Lambda‐Kalküls erfasst, nämlich die Martin‐Löfsche Typentheorie.

El contexto del Concilio Vaticano II vivió un aspecto fundamental que es necesario valorar: el clima de libertad, de apertura y alegría traído por el Concilio, sin coacciones, ni imposiciones sobre numerosos aspectos de la vivencia de la fe, ni moralismos, ni casuísticas sobrepasadas. Además de reflexiones teológicas para abrir nuevos caminos, el Concilio trajo un nuevo clima para la Iglesia. En América Latina, que sufría dictaduras asesinas, la Iglesia del Concilio era luz que sustentaba la evangelización y la lucha (...) por la justicia. Ahora, como en el periodo que precedió al Concilio, las señales de los tiempos perciben que algo tiene que ocurrir. Como entonces, es preciso superar la perplejidad y el temor, abriéndose a una gran esperanza. La búsqueda sigue, con la paciencia activa que soporta las “demoras de Dios”, aguantando sorpresas y contradicciones sin abatirse. Es un tiempo apropiado para vivir con intensidad la recomendación del Apóstol de ser “alegres en la esperanza, firmes en la tribulación, constantes en la oración” (Rm 12,12). - DOI: 10.5752/P.2175-5841.2011v9n24p1361.

The intention here is that of giving a formal underpinning to the idea of ‘meaning-is-use’ which, even if based on proofs, it is rather different from proof-theoretic semantics as in the Dummett–Prawitz tradition. Instead, it is based on the idea that the meaning of logical constants are given by the explanation of immediate consequences, which in formalistic terms means the effect of elimination rules on the result of introduction rules, i.e. the so-called reduction rules. For that we suggest an extension (...) to the Curry– Howard interpretation which draws on the idea of labelled deduction, and brings back Frege’s device of variable-abstraction to operate on the labels (i.e., proof-terms) alongside formulas of predicate logic. (shrink)

We are concerned with showing how ‘labelled’ Natural Deduction presentation systems based on an extension of the so-called Curry-Howard functional interpretation can help us understand and generalise most of the deduction calculi designed to deal with the logical notion of existential quantification. We present the labelling mechanism for ‘’ using what we call ‘ɛ-terms’, which have the form of ‘a’) in a dual form to the ‘Ax.f’ terms of in the sense that the ‘witness’ is chosen at the time of (...) assertion/introduction.With the intention of demonstrating the generality of our framework, we provide a brief comparison with some other calculi of existentials, including the model-theoretic interpretations of Skolem and Herbrand, indicating the way in which some of the classical results on prenex normal forms can be extended to a wide range of logics. The essential ingredient is to look at the conceptual framework of labelled natural deduction as an attempted reconstruction of Frege's functional calculus where the devices of the Begriffsschrift work separately from, yet in harmony with, those of the Grundgesetze 1.

Further to the connections between meaning and use, it seems useful to consider the consequences one is allowed to draw from a proposition as something directly related to its meaning/use. And indeed, Wittgenstein's references to the connections between meaning and the consequences, as well as between use and consequences are sometimes as explicit as his celebrated ‘definition’ of meaning as use given in the Investigations. Here we attempt to collect some of these references, discussing how an intuitive basis for the (...) construction of a more convincing proof-theoretic semantics for the mathematical language can arise out of this connection meaning/use/ consequences.

As a celebration of theTractatus100th anniversary it might be worth revisiting its relation to the later writings. From the former to the latter, David Pears recalls that “everyone is aware of the holistic character of Wittgenstein’s later philosophy, but it is not so well known that it was already beginning to establish itself in theTractatus” (The False Prison, 1987). From the latter to the former, Stephen Hilmy’s (The Later Wittgenstein, 1987) extensive study of theNachlasshas helped removing classical misconceptions such as (...) Hintikka’s claim that “Wittgenstein in thePhilosophical Investigationsalmost completely gave up the calculus analogy.” Hilmy points out that even in theInvestigationsone finds the use of the calculus/game paradigm to the understanding of language, such as “in operating with the word” (Part I, §559) and “it plays a different part in the calculus”. Hilmy also quotes from a late (1946) unpublished manuscript (MS 130) “this sentence has use in the calculus of language”, which seems to be compatible with “asking whether and how a proposition can be verified is only a particular way of asking ‘How do you mean?’” Central in this back and forth there is an aspect which seems to deserve attention in the discussion of a semantics for the language of mathematics which might be based on (normalisation of) proofs and/or Hintikka/Lorenzen game-dialogue: the explication of consequences. Such a discussion is substantially supported by the use of the open and searchableThe Wittgenstein Archives at the University of Bergen. These findings are framed within the discussion of the meaning of logical constants in the context of natural deduction style rules of inference. (shrink)

This article aims to present a discussion about childhood from the issues raised by the short film entitled Alma, directed, produced and scripted by the filmmaker André Morais. In the work, we experience a day in the life of a girl who lives with her grandmother and who, throughout the plot, weaves questions about her own existence, the senses of life and the dimensions of the relationships we establish with each other. It is discussed in this article, therefore, the power (...) of cinema and childhood as dimensions that invite a dialogue capable of converging art and life, also revitalizing the field of science, from the reflections that are dear to the dynamics of human experience. What conceptions of childhood are presented in the production? In what ways does the chosen approach broaden the discussion about childhood and cinema as potencies? To what extent do the questions raised by the child connect their childhood experience to the experiences of those who watch it on screen? In order to mobilize the discussion, the text is organized from scenes, which characterize the sequence of events that give meaning to what the film wants to express. In the first, the central theme is presented; in the second, the questions for which the short awakens us throughout the narrative; and in the third, it seeks to expand the possibilities of reading, rather than closing them. These scenes support the discussions brought here through Walter Benjamin, Mikhail Bakhtin, Antoine de Saint-Exupéry, Aristotle and Hannah Arendt. (shrink)

Introdução: As aulas virtuais se tornaram o principal meio de ensino das instituições educacionais diante da pandemia, e essa mudança repercutiu diretamente na autoestima dos estudantes e consequentemente nos rendimentos acadêmicos. Objetivo: avaliar a autoestima dos estudantes de enfermagem em contexto pandêmico. Metodologia: Trata-se de um estudo descritivo, com uma abordagem quantitativa. A coleta e análise de dados se deu a partir da escala de autoestima de Rosenberg (The Rosenberg Self-Esteem) e de instrumento complementar desenvolvido pelos autores. A pesquisa foi (...) realizada no Centro de Educação e Saúde da Universidade Federal de Campina Grande, com 155 estudantes do Curso de Bacharelado em Enfermagem. Resultados: Dentre os participantess, 60,7% apresentam valores que indicam uma autoestima diminuída de modo geral. Os números indicam que a maioria absoluta apresentava uma baixa autoestima, decorrente do período vivenciado na pandemia, com uma pontuação entre 7 e 12 no escore, o que representa 89,7% dos entrevistados. Isso mostra que o desgaste vivenciado pelos estudantes durante esse tempo é presente e notório. Conclusão: A baixa autoestima está presente entre os estudantes, como mostram os resultados obtidos através dessa pesquisa, que podem sugerir que essa autoestima diminuída seja advinda do período vivenciado pela pandemia.

The lambda calculus is a universal programming language. It can represent the computable functions, and such offers a formal counterpart to the point of view of functions as rules. Terms represent functions and this allows for the application of a term/function to any other term/function, including itself. The calculus can be seen as a formal theory with certain pre-established axioms and inference rules, which can be interpreted by models. Dana Scott proposed the first non-trivial model of the extensional lambda calculus, (...) known as $ D_{\infty }$, to represent the $\lambda $-terms as the typical functions of set theory, where it is not allowed to apply a function to itself. Here we propose a construction of an $\infty $-groupoid from any lambda model endowed with a topology. We apply this construction for the particular case $D_{\infty }$, and we see that the Scott topology does not provide enough information about the relationship between higher homotopies. This motivates a new line of research focused on the exploration of $\lambda $-models with the structure of a non-trivial $\infty $-groupoid to generalize the proofs of term conversion to higher-proofs in $\lambda $-calculus.
