This essay analyzes the historical and philosophical context that led to the basic concepts of stereochemistry proposed by Van’t Hoff and Le Bel. Although it is now well established that the key idea of tetrahedral carbon, and in general a geometric view of matter, was pioneered by other chemists, Van’t Hoff and Le Bel used this idea to solve the puzzle of optical activity, thereby establishing a direct linkage between structure and physical properties. It is also interesting to note that (...) their proposals came without experimental verification and they were largely based on experiments conducted by others. Philosophical arguments can, however, be invoked to satisfactorily validate this deductive reasoning. (shrink)

El siguiente artículo busca ser un aporte teórico y metodológico para quienes se enfrentan a la tarea de realizar análisis del discurso. En ese sentido, este texto está especialmente dirigido a estudiantes que piensan llevar a cabo esta tarea en sus tesis de egreso. Para lograr este desafío teórico y metodológico, a lo largo del artículo se responderán dos preguntas: ¿Por qué analizar el discurso? Y ¿cómo hacer análisis del discurso? Como vemos, la primera pregunta es de naturaleza explicativa y (...) la segunda de carácter metodológica.The following article seeks to be a theoretical and methodological contribution for those who are faced with the task of realizing discourse analysis. In this sense, this text is especially directed to students who intend to perform this task in their thesis. In order to achieve this theoretical and methodological challenge, all along the article, it will be answering two questions: Why doing discourse analysis? and How is discourse analysis performed? As we may observe, the first question is of an explicative nature and the second has a methodological character. (shrink)

Con la crisis de la Modernidad como contexto, se presenta en este ensayo una discusión sobre el Estudio de Caso como modalidad de investigación cualitativa. Su fundamentación epistémica incluye elementos marginados o excluidos del paradigma moderno, tales como: la complejidad, el investigador como e..

El artículo parte de la preocupación de saber cómo se está desarrollando la formación de investigadores en las universidades brasileñas. Una primera dificultad que se coloca es el predominio de un abordaje segmentado de la investigación científica. Eso lleva a un cuestionamiento sobre si particularmente las asignaturas de metodologías sirven para formar investigadores. Entre diversas dificultades, se incluyen desde aspectos epistemológicos hasta los impactos de las asignaturas metodológicas sobre la formación de los investigadores. Se cuestionan las estructuras de las disciplinas, (...) su relación con las metodologías, y las relaciones entre enseñanza metodológica y prácticas de investigación. Lo que está en juego es la formación de científicos sociales críticos en que se cuestionen diferentes separaciones extremamente rígidas de los procesos de formación.The present article focuses on the concern to know how the process of preparing investigators at Brazilian universities is being developed. One of the first difficulties being dealt with involves the predominant of segmented approach of the scientific investigation. This leads to the questioning of methodologies used to prepare these investigators. Among other several difficulties, the epistemological aspects up to the methodological ideas on the preparation of investigators are included. The structures of the subjects, their relation to the methodologies and the relations between methodological teaching and investigation practices are questioned. The preparation of critical social scientists in which extremely rigid different separations from the preparation processes is at stake here. (shrink)

En el presente artículo nos propondremos realizar una lectura detallada de la operación a partir de la cual León Rozitchner analiza críticamente el trabajo de Max Scheler y, en ese mismo acto, sienta las bases de lo que posteriormente se constituirá como el núcleo central de su filosofía. En la primera parte, analizaremos las razones por las que Rozitchner se dedica al estudio de la fenomenología de Scheler y la operación de lectura que pone en práctica. En los siguientes dos (...) apartados nos detendremos en dos nociones fundamentales que Rozitchner critica e invierte: el _corpus christi_ como totalidad espiritual y la concepción de persona. Terminado el análisis sobre su lectura de Scheler, nos detendremos en la categoría de absoluto-relativo, entendiéndola como la consecuencia más acabada de los desarrollos de su tesis doctoral. A modo de conclusión, señalaremos brevemente la relevancia de la categoría de absoluto-relativo para la comprensión de la obra de Rozitchner. (shrink)

We study versions of limit models adapted to the context of metric abstract elementary classes. Under categoricity and superstability-like assumptions, we generalize some theorems from 7, 15-17. We prove criteria for existence and uniqueness of limit models in the metric context.

We study notions of independence appropriate for a stability theory of metric abstract elementary classes (for short, MAECs). We build on previous notions used in the discrete case, and adapt definitions to the metric case. In particular, we study notions that behave well under superstability‐like assumptions. Also, under uniqueness of limit models, we study domination, orthogonality and parallelism of Galois types in MAECs.

El artículo presenta hechos estilizados sobre los doscientos años de historia económica brasileña según los liberales clásicos, nacionalistas y marxistas. Para ello se eligen algunos autores clásicos de cada orientación teórica por la influencia de sus interpretaciones. Mientras que los liberales clásicos alaban la dependencia económica y critican la lucha política por superar las herencias coloniales y neocoloniales, los nacionalistas y marxistas, de diferentes maneras, critican la dependencia y proponen superarla políticamente. En Brasil, los marxistas nunca han estado en el (...) poder, pero es claro un péndulo entre liberales y nacionalistas. La relevancia de la clasificación propuesta se ilustra al recordar que, hoy, Brasil es gobernado por un líder en la tradición del neoliberalismo autoritario latinoamericano inaugurado por Augusto Pinochet en 1973. Sin embargo, poco después de conmemorarse los 200 años de la independencia política en 07 de septiembre de 2022, la elección presidencial de octubre de 2022 puede marcar un nuevo giro en el péndulo hacia una visión nacionalista del pasado y el futuro de Brasil.

Written in the 12th century in Arabic by a faithful Jewish man, "The Guide" is a work that explores the contradiction a very intelligent mind clearly saw between the tradition he was raised to believe inherently and the growing philosophy of Arabian and Western culture. In Maimonides' time, there was an emerging disparity between the Law and a new level of philosophical sophistication, which he attempts to bridge in this work, primarily through the use of metaphor, though also acknowledging this (...) method's limitations. "The Guide" follows the form of a three-volume letter to a student, which was quickly translated to Hebrew and spread throughout the known world and carefully read by Jews and non-Jewish philosophers alike well through the Middle Ages. This work was so successful in its organization and arguments that it has long been a classic of the Jewish religion and of the secular world of philosophy. (shrink)

A pesquisa analisou a liberdade de expressão e a censura judicial no contexto inserido pela internet. Por meio do estudo bibliográfico e jurisprudencial, buscou-se definir o conteúdo do direito à liberdade de expressão e o seu exercício através da internet. Em seguida, passou-se a examinar o polêmico Inquérito das “fake news” (4.781 DF), do qual emanaram-se decisões colidentes com as garantias conferidas à liberdade de expressão. Por fim, após a discussão dos resultados, buscou-se evidenciar os perigos da censura judicial nas (...) plataformas virtuais. (shrink)

A partir de las reflexiones que en su O cosmopolitismo do pobre desarrolla Silviano Santiago, propondremos un enfoque alternativo al actual modelo de enseñanza nacional, o nacionalista (cuya sinonimia asumimos), de las literaturas, las culturas e incluso de las lenguas. Para ello, procedemos a problematizar-deconstruir la estructura ideológica nacionalista (Anthony Smith, Hobsbawm, Anderson), defendiendo las ventajas científicas y políticas de un enfoque transterritorial de los estudios culturales, lingüísticos y literarios.

In this paper, I discuss the possible relations between Fritz London’s account of the status of the observer in quantum physics and transcendental phenomenology. Firstly, I discuss Steven French’s interpretation of London’s thesis as a phenomenological account of the status of the observer, along with the objections Otávio Bueno has brought forward. Secondly, refusing in part both French’s and Bueno’s theses for several reasons, I propose another way of reading London’s thesis in the framework of transcendental phenomenology. Namely, I put (...) London’s account of the observer against the backdrop of Husserl’s analyses of the objectifying acts and objectual constitution. Finally, I end this article with some criticisms of what seems to me the ontological indigency of the Copenhagen interpretation of quantum physics, to whose “spirit” London also belongs. (shrink)

In this paper I discuss the consistency and accuracy of Husserl’s sketch of a theory about non-declarative sentences in the last chapter of Logical Investigations. Whereas the consistency is acknowledged, the accuracy is denied, because Husserl’s treatment of non-declarative phrases such as questions or orders implies that those phrases contain, in some way, a declarative sentence and an objectifying act. To construct a question like “is A B?” as being equivalent to a pseudo-declarative sentence such as “I ask whether A (...) is B” is, however, a false phenomenological analysis, because to ask o r to order or to beg is not to assert. I turn, then, to John Austin ‘s theory of performative (as opposed to constatative) utterances and illocutionary acts in order to find a more accurate approach to the logical-semantic content of non-declarative sentences. Eventually, I show how this Husserlian theory of non-declarative sentences has a negative impact on the phenomenological theory of social ·acts and communication. (shrink)

El artista chileno José Miguel Blanco tuvo un rol protagónico en la escena cultural del país durante la segunda mitad del siglo XIX. Aparte de su labor escultórica, traducida en una cantidad importante de obras, una buena parte de su quehacer estuvo vinculado con la escritura de arte, lo que se materializó, principalmente, en el periódico El Taller Ilustrado, el primer medio informativo en el país dedicado exclusivamente a temas de arte, que este escultor creó y dirigió por casi cinco (...) años. Desde esa tribuna Blanco promovió información, debates e iniciativas que favorecieron el desarrollo cultural del país. Este escultor es, sin lugar a dudas, el autor más prolífico en la escritura artística chilena de su tiempo. The Chilean artist José Miguel Blanco had a protagonic role in the culture scene in the country during the second half of the 19th century. Besides his works of sculpture, reflected in an important quantity of pieces of art, a great part of his work was related to the Artistic Writing, which was materialized, mainly in the newspapers called El Taller Ilustrado, the first informative media in the country dedicated exclusively to the topics of Art, that this sculptor created and managed for almost five years. From this tribune, Blanco promoted information, debates and initiatives that contributed to the development of culture in Chile. The sculptor is, without any doubt, the most prolific author in Chilean Artistic Writing in his time. (shrink)

El principio de racionalidad, o de economía, puede expresarse como la hipótesis de que los sujetos tienden a llevar a cabo aquellas acciones que maximizan la diferencia entre beneficios y costes. Este principio es ampliamente aplicado en las ciencias sociales, sobre todo, obviamente, en la teoría económica, si bien en el último medio siglo ha sido aplicado también de manera creciente a otras ramas de dichas disciplinas (sociología, ciencia política, antropología, historia, etc.). En este artículo se discute la posibilidad de (...) aplicarlo a la lingüística y la pragmática, comentando varios de los trabajos realizados desde ese punto de vista, e ilustrándolos con su aplicación al caso del uso de expresiones vagas.

Pathogenic bacteria frequently target the endoplasmic reticulum (ER) and mitochondria in order to exploit host functions. ER‐mitochondria inter‐organelle communication is topologically sub‐compartmentalized at mitochondria‐associated ER membranes (MAMs). MAMs are specific membranous microdomains with unique regulatory functions such as lipid synthesis and trafficking, calcium homeostasis, mitochondrial morphology, inflammasome activation, autophagosome formation, and apoptosis. These important cellular processes are all modulated by pathogens to subvert host functions and promote infection, thus it is tempting to assume that pathogenic bacteria target MAMs to subvert (...) these different pathways in their hosts. First lines of evidence that support this hypothesis come from Legionella pneumophila. This intracellular bacterium secretes an effector that exhibits sphingosine‐1 phosphate lyase activity (LpSpl) that seems to target MAMs to modulate the autophagy response to infection. Here we thus propose the concept that MAMs could be targeted by pathogenic bacteria to undermine key host cellular processes. (shrink)

Abstract:This article analyzes some of the issues raised by historians after turning to computers for historical research in the 1960s and 1970s. The main point is to enrich this context by looking into the debates computer programmers were having in their own field at the same time. In particular, the use of formal languages to enhance the theoretical basis of both practices is discussed. A second point, the debates in programming, is also highlighted: as historians were turning to computer programming, (...) programmers were becoming historians of their own practice, engaged in methodological discussions on how to write their history.
