In 1962 Tibor Radó uncovered a monster hiding in the midst of innocent-looking Turing machines.

We state and comment our recent results on the incompleteness of elementary real analysis and their relevance for the axiomatized sciences.

We give a overview of the main areas in theoretical physics, with emphasis on their relation to Lagrangian formalism in classical mechanics. This review covers classical mechanics; the road from classical mechanics to Schrödinger’s quantum mechanics; electromagnetism, special and general relativity, and gauge field theory and the Higgs mechanism. We shun mathematical rigor in favor of a straightforward presentation.

We discuss Kunen’s algorithmic implementation of a proof for the Paris–Harrington theorem, and the author’s and da Costa’s proposed “exotic” formulation for the P = NP hypothesis. Out of those two examples we ponder the relation between mathematics within an axiomatic framework, and intuitive or informal mathematics.

Este artículo presenta un estudio descriptivo, cuyo propósito es determinar si el comportamiento rítmico del habla en lectura en voz alta de personas profesionales de ocho ciudades diferentes de Chile coincide con la clasificación dada históricamente al español como lengua de ritmo silábico, clasificación que además en general se extiende a todas las lenguas romances. Varios estudios tradicionales afirman que el español es una lengua de tendencia hacia el ritmo silábico, no obstante, también existen otros trabajos, antiguos y recientes, que (...) afirman lo contrario, esto es, que el español manifiesta un comportamiento rítmico de tipo acentual. Hasta el momento, no se ha realizado un estudio de este tipo sobre este tema para el español de Chile. En el presente trabajo, se analiza un corpus de lecturas obtenidas de una muestra de 30 informantes de distintas regiones del país. El análisis se realiza con procedimientos de medición instrumental que entregan indicadores cuantitativos que han sido propuestos recientemente en el ámbito de la investigación sobre prosodia y que le otorgan, además, mayor precisión y objetividad a los estudios acerca de este tema. Los resultados muestran que en el español de Chile, en la lectura en voz alta, se manifiesta una tendencia rítmica de tipo silábico, aunque comparativamente tiende a ser más acentual que los valores que se han dado para el español peninsular. En cuanto a la variación del español de Chile por zona geográfica, las diferencias son tan pequeñas que no es posible afirmar que la variable diatópica influye en el comportamiento rítmico del español de Chile, en situación de lectura.

Este texto objetiva desenvolver discussão sobre os fundamentos dialéticos do desenvolvimento profissional docente. Estrutura-se na revisão de literatura com base em ideias de autores que abordam estudos sobre o desenvolvimento profissional docente e no conceito de desenvolvimento fundamentado nas leis gerais do Materialismo Histórico Dialético. Dentre os resultados constatados com o estudo, destaca-se a compreensão de que os autores analisados realizam discussão do desenvolvimento profissional docente como processo de constituição do ser professor relacionado a aquisição de saberes e competências necessárias (...) à profissão. A partir da discussão dos fundamentos dialéticos do desenvolvimento profissional docente, concluiu-se que o mesmo é o movimento histórico e dialético de constituição das maneiras de pensar, sentir e agir do professor e se manifesta nas suas relações pessoais, profissionais e institucionais. Palavras-chave: Pesquisa; Educação; Desenvolvimento Profissional; Processo Dialético. Dialectical Foundations of Professional Teaching Development Abstract: This text aims to develop discussions on the dialectical foundations of professional teaching development. It is structured in the literature review based on ideas of authors that address studies about the professional teaching development and in the concept of the development grounded on the general laws of Dialectical Historical Materialism. Among the results found due the study, we highlight the comprehension that the analyzed authors hold discussion on the professional teaching development as a constitution process of being a teacher related to the knowledge acquisition and the necessary competences in the profession. From the discussion on dialectical foundations of professional teaching development, it was concluded that it is the historical and dialectical movement of constitution of ways of thinking, feeling, and acting as a teacher and it is manifested in its personal, professional, and institutional relations. Keywords: Research And Education; Professional Development; Dialectical Process. Fondements dialectiques du développement professionnel des enseignants Résumé: Ce texte vise à développer discussion sur les fondements dialectiques du développement professionnel des enseignants. On structure dans la révision de littérature basée sur les idées d'auteurs qui abordent études sur le développement professionnel des enseignants et dans le concept de développement fondé dans les lois générales du Matérialisme Historique Dialectique.

Resenha do livro "Foucault e a crítica da verdade", de César Candiotto.

Current mathematical models are notoriously unreliable in describing the time evolution of unexpected social phenomena, from financial crashes to revolution. Can such events be forecast? Can we compute probabilities about them? Can we model them? This book investigates and attempts to answer these questions through GOdel's two incompleteness theorems, and in doing so demonstrates how influential GOdel is in modern logical and mathematical thinking. Many mathematical models are applied to economics and social theory, while GOdel's theorems are able to predict (...) their limitations for more accurate analysis and understanding of national and international events. This unique discussion is written for graduate level mathematicians applying their research to the social sciences, including economics, social studies and philosophy, and also for formal logicians and philosophers of science.

It is primordial to insist on a continuous education that is open, flexible, and personalized, allowing the individual to update and make his or her knowledge adequate throughout life. The creation of distributed environments for constructivist learning is a challenge. Research in this field is needed for the development of cooperative learning tools able to facilitate and motivate learning. The development of intelligent didactic systems is complex, demanding the support of knowledge coming from different fields. That is why to develop (...) this class of systems a multidisciplinary team is needed, including pedagogues; educational psychologists; specialists in the knowledge domain; and technicians in computer graphics, programming, multimedia, virtual reality, project management, and so forth. Virtual immersion introduces new resources for interindividual communications that deal with reality interpretation. The authors outline the beginning of a long journey on how imagination power can be used for the collective creation of worlds able to improve learning. (shrink)

Neste trabalho procuramos compreender as ideias que nortearam a ação de Frei Manuel do Cenáculo, enquanto reformador de estudos para diferentes níveis e bispo empenhado na formação do clero e dos fiéis da sua diocese. Tomamos como ponto de partida os anteriores trabalhos sobre a atuação política e pastoral de Cenáculo, para sistematizar a ação em defesa do ensino e o seu pensamento pedagógico. Como textos fundamentais para esta análise, salientamos os Cuidados Literários (1791), os documentos relativos ao plano de (...) estudos para a Terceira Ordem de S. Francisco e algumas das cartas pastorais, quer as que o bispo dirigiu para o clero, quer as dirigidas a todos os diocesanos. (shrink)

Este artigo apresenta como tema principal a teoria semântica de Frege para sentenças da linguagem natural e dos processos mentais associados à sua significação. Frege se fundamenta na análise da linguagem para distinguir na mente humana os elementos lógicos de outros de aspectos psicológico. Portanto, nossa investigação visa apresentar nos escritos de Frege a presença de uma teoria semântica relacionada ao encanto estético da arte poética e outra lógica ou associada às investigações científicas.

Maps and territory suggest problems which have to do with the opening of pathways in some poorly explored domain.

A presente pesquisa tem por objetivo refletir sobre alguns dos principais aspectos de Ubuntu, aqui considerado como uma das várias correntes da filosofia africana. A metodologia empregada neste trabalho caracteriza-se por ser de cunho qualitativo. Com efeito, trata-se de uma pesquisa bibliográfica cujo corpus compõe-se de literatura especializada. Esta investigação se justifica, considerando-se que a sociedade contemporânea é marcada, dentre outras coisas, por um individualismo e egocentrismo excessivos além de uma valorização da matéria em detrimento do humano. A filosofia Ubuntu, (...) que se traduz em “Eu sou, porque nós somos”, possui um potencial ético capaz de fortalecer um convívio social, no qual valores como a solidariedade, a confiança, o respeito, a generosidade são assumidos como fundamentais. Este trabalho investigativo chegou às seguintes conclusões: a filosofia Ubuntu representa uma das contribuições mais originais da filosofia africana; o potencial ético dessa corrente filosófica não deve ser desprezado pela filosofia brasileira; considerando que Brasil e África precisam aprender a pensar de modo descolonizado, é fato que os filósofos africanos estão mais comprometidos com essa tarefa do que os brasileiros, sendo a corrente filosófica Ubuntu um testemunho disso.

La relación existente entre el Estado y los ciudadanos remonta épocas antiguas, donde se le exigía la contribución para el pago de los gastos de la monarquía, con el desarrollo del hombre moderno nace la Relación Jurídica Tributaria, donde esta representa la personificación tanto de la potestad de imposición como del deber de contribución, mejor conocidos y aceptados como Sujeto Activo y Sujeto Pasivo, a través de las distintas acepciones, en tal sentido se analiza esta relación a la luz del (...) ordenamiento jurídico venezolano, enmarcada en una investigación de tipo documental, mediante la observación directa y aplicándola hermenéutica jurídica y teniendo como bases fundamentales la Constitución de la República Bolivariana de Venezuela (Asamblea Nacional Constituyente, 1999), Código Orgánico Tributario (Asamblea Nacional, 2001), jurisprudencia patria y de la doctrina tanto nacional como extranjera, se determinó en esta investigación la génesis de la Relación Jurídica Tributaria a través de los actores intervinientes, Sujeto activo, Sujeto Pasivo en sus distintas posiciones, contribuyente solidario, contribuyente Responsable, de igual forma la Relación Jurídica Tributaria desencuentra fundamentada en el hecho imponible, siendo esta la raíz de la tributación a cualquier nivel, bien sean impuestos, tasas o contribuciones. Igualmente la base imponible, significa representación monetaria del hecho imponible la cual será objeto de un tratamiento fiscal para una determinación de un tributo a pagar. (shrink)

The ongoing pandemic caused by coronavirus disease 2019 has enforced a shutdown of educative institutions of all levels, including high school and university students, and has forced educators and institutions to adapt teaching strategies in a hasty way. This work reviews the use of gamification-based teaching during the pandemic lockdown through a search in Scopus, PsycINFO, ERIC, and Semantic Scholar databases. A total of 11 papers from Chemistry, Business, Computer Science, Biology, and Medical areas have been identified and included in (...) the present work. All of them analyzed the use of gamification strategies during the COVID-19 pandemic and assessed student’s learning and motivation outcomes. In general, students reported that gamification was innovative, engaging, and an efficient strategy to deliver curricula material; moreover, it was perceived as a fun activity. Some students reported that gamified videoconferences aided to connect with their classmates during isolation time providing effective social support. However, some students reported a bad physical or psychological condition, as consequence of the confinement, and did not get involved in the activity. Some weaknesses of the reviewed studies are the small sample size and its homogeneity, which makes it difficult to generalize their results to other scenarios and academic areas. Furthermore, although there is a feeling of learning during the activity, this result is mainly based on subjective perceptions, and any of the studies demonstrated that superior learning was achieved in comparison with traditional teaching strategies. Nevertheless, gamification can be implemented together with traditional lectures and can be a valuable instrument during post-COVID times. (shrink)

O desejo de compreender o que, afinal de contas, cabe à filosofia realizar e, como consequência disso, qual papel está reservado ao filósofo, no jogo da vida e do conhecimento, embora bastante antigo (no Fédon, Platão já havia se esforçado para definir o que compete ao filósofo fazer), tendo recebido muita atenção ao longo do século XX, continua se mantendo bem atual. Assim, nesta exposição, nós também trataremos disso, entretanto, fazendo um recorte, o continente africano. Desse modo, o nosso objetivo (...) principal aqui é discutir a práxis filosófica, partindo do princípio de que esse tipo de intelectual, apesar de suas ligações próprias com o ambiente teórico, é indissociável da vida concreta, experimentada pelo homem em seu cotidiano. Nesse debate, dialogaremos com pensadores africanos (como Kwasi Wiredu, que destaca a importância do conhecimento filosófico para a modernização da África) e ocidentais. (shrink)

This volume presents essays by pioneering thinkers including Tyler Burge, Gregory Chaitin, Daniel Dennett, Barry Mazur, Nicholas Humphrey, John Searle and Ian Stewart. Together they illuminate the Map/Territory Distinction that underlies at the foundation of the scientific method, thought and the very reality itself. It is imperative to distinguish Map from the Territory while analyzing any subject but we often mistake map for the territory. Meaning for the Reference. Computational tool for what it computes. Representations are handy and tempting that (...) we often end up committing the category error of over-marrying the representation with what is represented, so much so that the distinction between the former and the latter is lost. This error that has its roots in the pedagogy often generates a plethora of paradoxes/confusions which hinder the proper understanding of the subject. What are wave functions? Fields? Forces? Numbers? Sets? Classes? Operators? Functions? Alphabets and Sentences? Are they a part of our map? Or do they actually belong to the territory? Researcher, like a cartographer, clothes the reality by stitching multitudes of maps that simultaneously co-exist. A simple apple, for example, can be analyzed from several viewpoints beginning with evolution and biology, all the way down its microscopic quantum mechanical components. Is there a reality out there apart from these maps? How do these various maps interact/intermingle with each other to produce a coherent reality that we interact with? Or do they not? Does our brain uses its own internal maps to facilitate “physicist/mathematician” in us to construct the maps about the external territories in turn? If so, what is the nature of these internal maps? Are there meta-maps? Evolution definitely fences our perception and thereby our ability to construct maps, revealing to us only those aspects beneficial for our survival. But the question is, to what extent? Is there a way out of the metaphorical Platonic cave erected around us by the nature? While “Map is not the territory” as Alfred Korzybski remarked, join us in this journey to know more, while we inquire on the nature and the reality of the maps which try to map the reality out there. The book also includes a foreword by Sir Roger Penrose and an afterword by Dagfinn Follesdal. (shrink)

Com a saída do colonizador do controle político, nos países do continente africano, abriu-se um espaço de poder que passou a ser disputado. É neste contexto que consideramos aqui os processos voltados a implantar regimes democráticos, em solo africano. Assim, a pesquisa de PIBIC que deu origem a este escrito investigou o seguinte problema: Como definir a questão da democracia em África? Dito de outro modo: Quais são as características principais presentes nesta discussão? Utilizando como metodologia de trabalho a pesquisa (...) teórica, constatou-se que a história do engendramento da democracia em terras africanas (no recorte temporal utilizados por nós, nesta pesquisa, isto é, o período pós-colonial) liga-se a três modelos distintos de democracia: o liberal, o monopartidário e o consensual. O artigo orienta a discussão, destacando os seguintes pontos: a democracia proposta à África é um projeto elaborado pelo Ocidente; as resistências enfrentadas por ela, em solo africano, desde o início do período pós-colonial; a tarefa reservada à filosofia, nos esforços de democratização do referido continente.

We conjecture that the existence of some fast-growing functions implies in a simple way the existence of some inaccessible cardinals. This note expands some previous work by the second author.

In Mexico, there is little research on the study of self-injury and even less on possible explanatory models. With this in mind, this study aimed to determine the relationship between self-injury and depression, emotional dysregulation, and coping styles, to generate an explanatory model of the problem. The study was carried out using a quantitative, cross-sectional, explanatory scope, design and a sample of 5835 adolescents enrolled in 62 public high schools in the state of Sonora. Logistic regressions were performed for data (...) analysis, and as a result it was found that, for students with severe self-injury, the model explains 61 % of the variance in the data and correctly classifies 84.1 % of the participants; whereas, in mild self-injury, the model explains 72 % of the variance in the data and correctly classifies 88.2 % of the students. Likewise, the depression dimensions showed the highest explanatory level and positive correlations with emotional dysregulation and avoidance coping style, as well as negative correlations with approach coping style. At the end, the importance of the independent variables for future research is discussed, as well as anomalous results and other data of interest. (shrink)

Objetiva-se fazer uma análise do atual cenário de avanço das ferramentas digitais no campo da Comunicação tomando como referência analítica as mudanças nos processos informativos em nível local em contraste com a predominância de uma editorialização global-metropolitana. A partir dos novos paradigmas sociais, econômicos e tecnológicos consequentes da reconfiguração das plataformas, conteúdos e linguagens midiáticas, busca-se fazer uma discussão sobre as possibilidades e eventuais empecilhos para o desenvolvimento de um jornalismo radiofônico plural, independente e cidadão em âmbito local.

In this paper the structure of pretemporal algebra is used to study some aspects of temporal algebras and modal algebras. The paper contains a computational approach to finite temporal algebras and a general splitting theorem for finite temporal algebras.

In the paper we obtain a new characterization of the BCK-algebras which are subdirect product of BCK-chains. We give an axiomatic algebraizable extension of the BCK-calculus, by means of a recursively enumerable set of axioms, such that its equivalent algebraic semantics is definitionally equivalent to the quasivariety of BCK-algebras generated by the BCK-chains. We propose the concept of "linearization of a system" and we give some examples.

In this paper an algebraic version for temporal algebras of the logical filtrations for modal and temporal logics is analysed. A structure theorem for free temporal algebras and also some results with regard to the variety of temporal algebras are obtained.

Esse texto é um escrito que, ao final, é um termo médio entre um Artigo e um Ensaio. O objetivo é expor nossa compreensão sobre o sentido d“o material” e as implicações onto(epistemo)lógicas desta concepção no pensamento de Karl Marx. Em plano geral, primeiramente, nosso texto discorre sobre o que nomeamos de “a questão primeira”, qual seja: o que é “o material” no interior e no contexto dos escritos de Marx? Para cumprir essa tarefa procedemos com leituras de textos marxianos (...) visando identificar, neles, passagens importantes aonde o conceito de “material” é pressuposto, citado ou implicado. No segundo momento do texto, afirmamos que os resultados das análises do sentido d“o material” nos possibilitam induzir e/ou deduzir que o materialismo de Marx é dialético. Por fim, apresentamos algumas conclusões que decorrem do aceite da validade e veracidade da tese de que Marx pensa dialeticamente, de que seu materialismo é dialético. (shrink)

En este trabajo se argumenta que no es posible contar objetos reales. Aunque a primera vista esta tesis pueda resultar desconcertante, o un simple ejercicio de «arte conceptual», las razones que la apoyan son fundadas y muy naturales. Se examinan algunas consecuencias importantes de dicha tesis y se ponen en conexión con diversos planteamientos de H. Putnam, P. Unger y E. Sosa.

El siguiente informe pericial se basa en la experiencia de investigación de los firmantes en relación a las exhumaciones de fosas comunes de la Guerra Civil y la postguerra, y al conocido como “movimiento para la recuperación de la memoria histórica” que están teniendo lugar en España desde el año 2000, que ha enfatizado sus demandas sobre la suerte de los desaparecidos y ha puesto en marcha un ciclo de exhumaciones de fosas comunes derivadas de la Guerra Civil y la (...) dictadura. En este peritaje se usan las exhumaciones del siglo XXI como indicadores de la persistencia en el tiempo de las políticas y culturas del miedo instaladas en la sociedad española durante la Guerra Civil y la dictadura, más allá de las profundas transformaciones políticas e institucionales acaecidas en el país tras la muerte de Francisco Franco. Fue presentado como parte de la documentación de la demanda de Fausto Canales contra España el 15 de septiembre de 2012 en el Tribunal Europeo de Derechos Humanos. (shrink)

The theme of ecology is much more than a trend or a politically correct subject. What is at stake is the maintenance of life upon the Earth, including the very human survival which depends on the environment. This article is an effort towards relating ethics with the environmental and ecological issues. It starts with the matter of free will which brings the fundamental need of ethics. Then there are a few considerations on ethics and the challenge to expand this concept (...) beyond the human scope. Some environmental issues are presented, among which the preservation of forests, the dignity of animals and meat consumption, with considerations based on ethical principles. Last but not least, there is the aid of Christian teachings, relating the Parable of the Good Samaritan with the teachings of Saint Francis of Assisi, in the hope of contributing to a clearer view on the subject and perhaps touching a few hearts.

Las micotoxinas son metabolitos fúngicos secunda­rios que pueden ejercer un efecto tóxico tanto en el hombre como en los animales debido, principalmente, a su exposición a través de los alimentos. La presencia de estos compuestos ha sido demostrada en una amplia variedad de materias primas, alimentos y piensos, en los que lo habitual es encontrar de for­ma frecuente una contaminación múltiple por diferentes mico­toxinas, en pequeñas cantidades, lo que puede generar efectos tóxicos subcrónicos, así como bioacumulación. Este artículo revisa los (...) principales elementos que configuran la problemática de las micotoxinas para el hombre y los animales, y aborda los retos de futuro que se plantean en el estudio de las micotoxinas, entre los que destacan el efecto que el cambio climático puede tener sobre el patrón de contaminación por micotoxinas en los alimentos, el descubrimiento creciente de nuevas micotoxinas en formas modificadas, la evaluación de la coexistencia de estas to­xinas y otros contaminantes, y las formas para detectar e intentar eliminar estos compuestos tóxicos de los alimentos.

Psychological flexibility is a key concept of acceptation and commitment therapy. This factor has been linked with psychological wellbeing and associated factors, such as quality of life, in cancer patients. These and other positive results of acceptation and commitment therapy in cancer patients found in previous research could be enhanced by using mhealth tools. A three-arm randomized superiority clinical trial, with a pre-post-follow-up repeated measures intergroup design with a 1:1:1 allocation ratio is proposed. A hundred and twenty cancer patients will (...) be randomly assigned to one of the following interventions: face-to-face ACT + mobile application, face-to-face ACT, and Waitlist control group. The primary expected outcome is to observe significant improvements in psychological flexibility acceptance and action questionnaire- II in the face-to-face ACT + app group, after comparing baseline and post-treatment scores, and the scores will remain stable in the two assessment points, 3 and 6 months after the intervention. Secondary expected outcomes are significant increasing scores in quality of life and post-traumatic-growth, and significant decreasing scores in anxiety and depression, insomnia and fatigue at the same assessment points. Also, it is expected that the scores of this group will be higher than the scores of the face-to-face ACT group and the waitlist control group. This study aims to assess the efficacy of a combined intervention for psychological flexibility and associated symptoms in cancer patients. The results of this protocol may help to consider the use of acceptation and commitment therapy and mhealth applications in cancer settings as a valid therapeutic choice.Clinical Trial Registration[www.ClinicalTrials.gov], identifier [NCT05126823].

In this paper a definition of n-valued system in the context of the algebraizable logics is proposed. We define and study the variety V3, showing that it is definitionally equivalent to the equivalent quasivariety semantics for the “Three-valued BCK-logic”. As a consequence we find an axiomatic definition of the above system.

One of the objectives in the field of artificial intelligence for some decades has been the development of artificial agents capable of coexisting in harmony with people and other systems. The computing research community has made efforts to design artificial agents capable of doing tasks the way people do, tasks requiring cognitive mechanisms such as planning, decision-making, and learning. The application domains of such software agents are evident nowadays. Humans are experiencing the inclusion of artificial agents in their environment as (...) unmanned vehicles, intelligent houses, and humanoid robots capable of caring for people. In this context, research in the field of machine ethics has become more than a hot topic. Machine ethics focuses on developing ethical mechanisms for artificial agents to be capable of engaging in moral behavior. However, there are still crucial challenges in the development of truly Artificial Moral Agents. This paper aims to show the current status of Artificial Moral Agents by analyzing models proposed over the past two decades. As a result of this review, a taxonomy to classify Artificial Moral Agents according to the strategies and criteria used to deal with ethical problems is proposed. The presented review aims to illustrate (1) the complexity of designing and developing ethical mechanisms for this type of agent, and (2) that there is a long way to go (from a technological perspective) before this type of artificial agent can replace human judgment in difficult, surprising or ambiguous moral situations.

El presente estudio propone un enfoque crítico de la cuestión del mal y del sufrimiento humano. En el marco del pensamiento ético de Levinas y desde una nueva perspectiva respecto de la concepción actual del lenguaje y del cuerpo, pretendemos cuestionar todas las formas de racionalismo y comprensión metafísica acerca del dolor y del sufrimiento humano. El propósito del presente estudio consiste en delinear una nueva forma de comportamiento en torno a la cuestión del mal y la debilidad humana, buscando (...) alternativas conceptuales para esclarecer este complejo problema ético.
