Dentro de la serie sobre Filosofía de la editorial Paragon, que tiene como objetivo general la publicación de textos introductorios completos en sí mismos para estudiantes de licenciatura, se presenta este libro de Fetzer, reconocido autor y editor de monografías de filosofía del lenguaje, de la mente, de la Inteligencia Artificial y de la Ciencia Cognitiva. Precisamente el libro pretende ser “una introducción filosófica a la ciencia cognitiva”, escrito de manera sencilla y accesible a los lectores previstos, evitando consecuentemente descender (...) a la exposición de detalles y al uso extensivo de técnicas formales. Ello obliga al autor a sostener a veces un discurso excesivamente general y una argumentación poco fina, pero las ventajas para los estudiantes de filosofía que se introducen de este modo en los principales programas de investigación en ciencia cognitiva resultan claras. No es otra la finalidad del autor sino la de exponer por qué es necesaria y cómo es posible una ciencia de la cognición, que emerge como “interdisciplina” fecundada por la psicología cognitiva, la linguística y la inteligencia artificial, recurriendo a estudios de la neurología y al uso de instrumentos formales.

La Agenda 2030 para el Desarrollo Sostenible promueve una sociedad inclusiva. Por eso debemos iniciar este proceso de convivencia intercultural desde la etapa de Educación Infantil. A través del eje central del cuento infantil y utilizando la música como recurso didáctico motivador, sustentaremos la acción docente en tres ejes de categorías: comunicación, imagen y sonido. Metodológicamente, se propone desde una perspectiva cualitativa y cuantitativa, a través del método etnográfico. El contexto se circunscribe a un centro educativo con un alumnado vulnerable. (...) Los resultados han permitido superar prejuicios y estereotipos y construir espacios de inclusión escolar. (shrink)

Today it is difficult to investigate how to deal with the interaction of heterogeneous societies living in common spaces of coexistence. Certainly, the intervention in this field of scientific knowledge requires to know and to be able to apply the concepts, models and paradigms of social relation that differ considerably according to the social context in which we are investigating. It is not the same, contextualizing this situation in the American society, or in the European, Asian or Latin American, to (...) give some examples. The education, through a new concept of sociocultural relations, specific to each context, will favour the establishment of ties to promote and encourage the coexistence of peoples. This coexistence in the social context of Latin America is based on the momentum generated by the Indigenous Peoples that have led to profound changes in educational paradigms and social relations. The new situation causes the interaction of such disparate concepts as intra- and transculturality through the incidence of identity in the context of globalization. (shrink)

Intermediate filament (IF) proteins form the largest family of cytoskeletal proteins in mammalian cells. The function of these proteins has long been thought to be only structural. However, this single function does not explain their diverse tissue‐ and differentiation‐specific expression patterns. Evidence is now emerging that IF also act as an important framework for the modulation and control of essential cell processes, in particular, signal transduction events. Here, we review the most recent developments in this growing and exciting new field. (...) BioEssays 24:836–844, 2002. © 2002 Wiley Periodicals, Inc. (shrink)

Este libro pertenece a la colección “The problems of Philosophy. Their past and present”, cuyo editor general es Ted Honderich. Como ya el título de la colección indica, lo que se pretende en cada volumen es recoger un problema importante, dentro de la filosofía, y presentar alguna nueva contribución. Cada libro se divide en dos partes. En la primera se hace una exposición histórica del problema y en la segunda el autor realiza su contribución. Con respecto a la configuración del (...) libro, nuestra única objeción es la distribución de las notas. Ponerlas al final del libro, justo antes de la bibliografía, no hace sino dificultar e interrumpir la lectura. Por lo demás pienso que es una idea excelente situar el problema históricamente; aunque quizás se le dedique demasiado espacio, al menos en este volumen. (shrink)

La democracia, entendida como el horizonte moral de la sociedad occidental, ¿necesita la terminación de la filosofía como saber fundante último? ¿Conllevan todos los relatos del fin de la filosofía una derrota de la verdad en favor de la opinión, una transformación y subordinación del propio discurso filosófico a la forma de convivencia que se considera más justa, más abierta, más inclusiva? Dicho de otra manera, ¿la pregunta sobre qué tipo de vocabulario y de acercamiento filosófico puede servir mejor a (...) la libertad humana tiene que ser la pregunta filosófica fundamental? ¿Habría que hacerle entonces a la filosofía las mismas terroríficas preguntas que Lenin le hizo a la libertad: filosofía sí, pero, ¿para quién, para hacer qué? A lo largo de este ensayo, se abordan estas cuestiones de la mano de dos relatos que teorizan el final de la filosofía con más de cuatrocientos años de diferencia. el primer relato es obra de Thomas Hobbes. el segundo, lo protagonizan Gianni Vattimo y Richard Rorty. el juego de espejos que se estable en el texto entre ambas narrativas quiere ser una reflexión sobre la identidad del discurso filosófico y su implementación en la institución universitaria en el marco de las democracias del siglo XXI.

The "people of knowledge" of traditional Mazatec medicine have preserved until today the ritual use of psilocybin mushrooms as part of their health care systems. The renewed interest in the effect of psilocybin on human consciousness for both therapeutic and recreational purposes usually obviates the historical and cultural background of indigenous peoples, as well as the legitimation of their practices and knowledge. In this article, through the case study of a foreign person who attended a Mazatec ritual specialist to participate (...) in a ritual night ceremony known as velada, we show the importance of approaching research on psychoactive plants and mushrooms from a transdisciplinary and intercultural perspective, so that we can appreciate the profound complexity of the healing processes that take place in traditional indigenous contexts, as well as the limits of recreational uses or exclusively neopositivist and clinical approaches.

This article tries to unravel some of the main clues provided by Ortega on his understanding of philosophy. The thesis we defend is that the Spanish philosopher maintains two slightly different answers concerning the question what is philosophy, though Ortega does not acknowledge them in the explicit narrative of his thinking. This, we believe, creates tensions in his late second philosophical model, as he does not fully break away from certain “adherence” or “mannerisms” associated to his early model. In this (...) respect, Ortega would be a thinker who lives between two philosophical worlds, someone who sees, narrates and interprets the philosophical shock wave occurring at his time, but does not quite let go of the old intellectual constructions. To support our thesis, we will compare two texts, his 1929 lectures What is Philosophy?, and his Notes on Thinking, from 1941. In the period between these two works, Ortega seems to move from a more “traditional,” “universalistic,” “transcendental,” in short, Husserlian phenomenological understanding of philosophy, to a more historicist, hermeneutical, and pragmatic one, which lays the emphasis on the plurality of discourses on the sense, the contingency of the philosophical narrative itself, and even the very possibility of its ending, at least in its more “metaphysical” and classical form.

RESUMENEl presente artículo es una exposición reflexiva del texto de Aron Gurwitsch "On Contemporary Nihilism". Escrito en plena conflagración mundial, su intención última es mostrar que el nihilismo, en tanto que fenómeno que define la situación de occidente desde el declive de las ideas racionalistas, es el sustrato común, la base de la que van a emerger, por un lado, el "nihilismo epistemológico", que afecta a los diferentes saberes, y, por el otro, el terrible hecho del totalitarismo. Frente a esta (...) situación, Gurwitsch defenderá que la única manera de salir del nihilismo y recuperar la cordura y la dignidad del ser humano es volviendo a reactivar, en el sentido husserliano, el ideal racionalista, el famoso dar y recibir razones con el que un día nació la filosofía en Grecia.PALABRAS CLAVENIHILISMO-TOTALITARSMO-RACIONALIDAD-ABSOLUTOABTRACTThis article is an expostion and a reflection on Aron Gurwitsch´s "On Contemporary Nihilism". He worte this text during the Second World War and his ultimate intention was to show that nihilism, as the fact which defined the situation of the West since the decline of the rationalistic ideas, was the common base from which two phenomena arose. The first of them is the "epistemological nihilism", which affects our theoretical and practical disciplines. The second one is the terrible fact of totalitarianism. Taking this situation into account, Gurwitsch will maintain that the only way to overcome hilism and to recover the dignity of the human being is through the re-activation, in the husserlian sense, of the rationalist ideal, the famous "lógon diadónai" with which a long time ago philosophy was born in Greece.KEYWORDSNIHILISM-TOTALITARISM-RATIONALITY-ABSOLUTE.

En este ensayo su autor revisita el tópico fenomenología trascendental e historia 12 años después de la publicación de un trabajo amplio sobre el tema. El escrito esta dividido en tres partes donde se muestras acuerdos y discrepancias con esa interpretación inicial. En la primera se rebate la tesis tan extendida de que la fenomenología de Husserl es alérgica a la historia y se establece una conjetura razonable sobre por qué, y a pesar de la evidencias en contra, sigue todavía (...) bastante vigente esa idea entre los no versados en su obra. En la segunda parte, se muestra en positivo la articulación entre fenomenología e historia y se concluye que la manera quizá más adecuada de entender el sentido último del pensamiento de Husserl es comprenderlo como una teoría transcendental de la historia. Para mostrar esto se expondrá, en primer lugar, el hecho crucial del paso de la fenomenología estática a la fenomenología genética. En segundo lugar, se incidirá en la mutua interconexión entre historia intencional, a priori de la historia y filosofía o teleología de la historia. Por fin, en una tercera y última parte, se realizan algunas valoraciones críticas de las ideas husserlianas. También una autocrítica de algunas partes del mencionado trabajo publicado hace 12 años. Todas tienen que ver, en última instancia, con lo que hoy entiendo como excesiva potencia de la teleología de la historia y la idea de racionalidad y fundamento que la animan.In this essay, the author revisits the topic transcendental phenomenology and history 12 years after the publication of a book on the subject. The paper is divided into three parts and shows agreements and discrepancies with that initial interpretation. The first part contradicts the widespread thesis that Husserl's phenomenology is allergic to history, and develops a conjecture about why, despite the evidence to the contrary, this thesis is still quite common among those not strictly versed in Husserl’s work. The second part shows the positive articulation among phenomenology and history. It concludes that the best way to understand the ultimate meaning of Husserl's thought is considering it as a transcendental theory of history. In order to show the plausibility of this reading, this part of the essay will expose, first, the step from static to genetic phenomenology, and secondly, the mutual interconnection between intentional history, a priori of history, and philosophy or teleology of history. Finally, in a third and final part, some critical assessments of Husserl's ideas are made, also a criticism of the mentioned book of the author of the paper published 12 years ago. They are concerned, ultimately, with what I now understand as an excessive power of teleology of history and the idea of rationality and foundation that animates it. (shrink)

This paper presents the design, simulation, and experimental verification of the fractional-order multiscroll Lü chaotic system. We base them on op-amp-based approximations of fractional-order integrators and saturated series of nonlinear functions. The integrators are first-order active realizations tuned to reduce the inaccuracy of the frequency response. By an exponential curve fitting, we got a convenient design equation for realizing fractional-order integrators of orders from 0.1 to 0.95. The results include simulations in SPICE of the mathematical description and the electronic implementation (...) and experimental measurements that confirm them. Monte Carlo and sensitivity tests revealed a robust realization. Contrary to its passive counterparts, the suggested realizations significantly reduce design and implementation efforts by favoring resistors and capacitors with commercial values and reducing hardware requirements.

The key problems and challenges connected with the Covid-19 pandemic in the field of education in sub-Saharan Africa are described in this paper. The study is based on the information collected from teachers and parents during the lockdown. The main problems connected with the organization of distance learning, such as the availability and accessibility of electricity and stable communications, were described. The main questions connected with the support of e-learning such as unequal access to distance education platforms and tools and (...) readiness of teachers of public and private schools were described. Key social and demographic challenges and threats to sustainable e-learning, such as critical overload of teachers, child mobilization for domestic tasks, age, ethnic and gender-based harassment and violence were analyzed. It was found that the main risks are the rapid and uncontrolled commercialization of education and the decline of public schools, which leads to a decrease in the quality of education and increasing inequality. It was concluded that pandemic-induced risks in education are non-linear and heterogeneously spatially, temporally, and socially distributed. The successful strategy of these risks reduction aimed at sustainable education should be based on transition plans, which must include not only the development of sustainable education but also the fighting against inequality.

The aim of this study was to analyze the psychometric properties of the Eating Disorder Inventory (EDI)-3 test to evaluate eating disorders in young Chilean population. Methods: The sample consisted of 1,091 Chilean adolescents and young people (i.e., 476 men and 615 women) between 15 and 28 years old, from the metropolitan region, and four regions from the coast and south-central zone of the country. The reliability and factorial structure of the instrument were analyzed, replicating the confirmatory factor analyses ofBrookings (...) et al. (2020), evaluating four additional models that included bifactor exploratory structural equation modeling (ESEM), bifactor, and two-bifactor. Results: A majority of the subscales presented alphas and omegas equal to or greater than 0.70, with the exception of asceticism (α = 0.543, ω = 0.552) and interpersonal alienation (α = 0.684, ω = 0.695) scales, which are consistent with the values of the Spanish and Mexican non-clinical samples. The best fit indices were obtained by the ESEM two-bifactor model, with twelve specific factors corresponding to the EDI-3 subscales and two general orthogonal factors (i.e., risk subscales and psychological subscales), consistently with the theoretical basis.
