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)

El proceso de despoblación rural en el Valle del Genal se ha visto agravado en las últimas décadas, provocado en parte por el éxodo de sus habitantes en la búsqueda de oportunidades laborales o mejores servicios y equipamientos. La proximidad de la Costa del Sol, en continuo crecimiento turístico desde los años 60, ha sido un fuerte atractor de población activa, favoreciendo esta dinámica. La interrelación entre ambos territorios supone una temática de sumo interés y una oportunidad como laboratorio de (...) estudio e investigación en el marco de la asignatura “Patrimonio, Turismo y Territorio” de la Escuela de Arquitectura de Málaga.

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)

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 Schrodinger's quantum mechanics; electromagnetism, special and general relativity, and (very briefly) gauge field theory and the Higgs mechanism. We shun mathematical rigor in favor of a straightforward presentation.

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.

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. Parmi les résultats constatés avec l'étude, on met en évidence la compréhension que les auteurs analysés réalisent discussion du développement professionnel des enseignants comme processus de constitution d’être professeur lié à l'acquisition de connaissances et compétences nécessaires à la profession.

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 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.

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

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)

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)

A partir del análisis del ambientalismo desde las perspectivas que brindan diferentes discursos sobre desarrollo sostenible, los autores argumentan que, en un nivel de aplicación local, en comunidades y proyectos específicos, se pueden generar nichos de sostenibilidad, pese a que reconocen la extrema dificultad de este desafío; comparan viejas y nuevas propuestas para alcanzar la sostenibilidad, tales como: el desarrollo sostenible, el capitalismo natural, el decrecimiento sostenible o el ecologismo de los pobres. Por último, presentan dos casos con particularidades diferentes, (...) en los que comunidades pobres se resisten a la Raubwirtschaft o economía industrial de rapiña dominante, al buscar la construcción de nichos de sostenibilidad desde una perspectiva local y de comunalidad, mediante el ordenamiento comunitario territorial, la gobernanza democrática y la planeación participativa.

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

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.

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)

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.

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)

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)

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.

Authoritative school climate is a relevant and novel construct that improves the academic performance and social-emotional development of students. This study aimed to evaluate the psychometric properties of reliability and validity of the Authoritative School Climate Survey (ASCS) in a sample of Chilean adolescents. A cross-sectional study was carried out, in which 808 students from 12 schools in Chile participated (55.1% men and 44.9% women), with a mean age of 15.94 (SD= 1.32). The results obtained through exploratory and confirmatory factor (...) analyzes ratified the hypothesized structure of two correlated factors. As expected, evidence of criterion validity showed significant relationships between the measures of authoritative school climate and attitude toward institutional authority. This study provides evidence regarding the psychometric quality of the scale to assess authoritative school climate, allowing its use in the Chilean context. (shrink)

El artículo presenta algunos de los diferentes modelos teórico-explicativos sobre las necesidades humanas; revisa el estado del arte en las publicaciones recientes, y evalúa críticamente las limitaciones y potenciales que ellas tienen, desde una mirada sistémica y fenoménica desde un enfoque centrado en la persona.

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.

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.

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.

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)

Uterus transplantation (UTx) research has been introduced in several countries, with trials in Sweden and the United States producing successful outcomes. The growing interest in developing UTx trials in other countries, such as Spain, the Netherlands, Japan, and Australia, raises important questions regarding the ethics of surgical innovation research in the field of UTx. This paper examines the current state of UTx in the context of the surgical innovation paradigm and IDEAL framework and discusses the ethical challenges faced by those (...) considering the introduction of new trials. We argue that UTx remains an experimental procedure at a relatively early stage of the IDEAL framework, especially in the context of de novo trials, where protocols are likely to deviate from those used previously and where researchers are likely to have limited experience of UTx. We conclude that countries considering the introduction of UTx trials should build on the strengths of the reported outcomes to consolidate the evidence base and shed light on the uncertainties of the procedure. Authorities responsible for the ethical governance of UTx trials are advised to draw on the ethical framework used in the oversight of surgical innovation. (shrink)

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.

[EN]In recent decades, problems related to the accessibility and sustainability of science have increased, both in terms of the acquisition and dissemination of knowledge and its generation. Policymakers, academics, and, increasingly, citizens themselves have developed various approaches to this issue. Among them, citizen science is distinguished by making possible the generation of scientific knowledge by anyone with an interest in doing so. However, participation alone does not guarantee knowledge generation, which represents an epistemological challenge for citizen science. Simultaneously, economic and (...) socio-institutional difficulties in science governance and maintenance have grown. To solve those problems, several market elements have been introduced, a solution rejected by those who consider science as a public good that states must guarantee. Alternatively, research and work on the commons are growing worldwide, the concept being extended from natural resources to knowledge resources. In this chapter, we propose science as a commons, underlining the essential role of citizen science. Difficulties also apply to citizen science itself, but the increasing development of a multitude of projects based on cooperation favours the conditions required for its sustainability and quality. Our philosophical proposal is based on empirical knowledge about citizen science coupled with socio-economic concepts, according to a sociopolitical epistemology. (shrink)

This is a critical-hermeneutical and historical-comparative study on Political Economy, Economic History and Social Thought, applied to the American utopias in the 19th century and its role in the colonisation of the United States (US) west. This review is based on a heterodox economic approach, used in the disciplines of Religion and Economics. It gives a general view of religious and ideological utopias, as cooperative enterprises of intentional life in farms and workshop, making a comparative analysis of efficiency and sustainability. (...) This study attempts to explain the colonial paradox of American utopias because the last established, with more inversion, they were the first to fall. This study shapes the development of the western territories, from the Quaker’s Holy Experiment framework and its support for the utopias experiments in the expansion to Ohio, Indiana and Illinois. Contribution: This review offers a descriptive and explanatory study on the colonisation of the US west, under the hermeneutical turn from heterodox economic approaches, to deal with some current contradictions and anachronism in the mainstream view. Also, there is a systematisation of the American utopias, divided into religious and ideological experiments, with a comparison. (shrink)
