Neste ensaio, gostaria de esclarecer, por meio da filosofia de Mayz Vallenilla, a estreita relação que existe entre técnica e alienação, como uma filosofia da técnica que se preocupa com o comportamento do homem, portanto, com sua alienação. Como resultado, este ensaio será dividido em três partes: na primeira seção, será desenvolvido um diálogo entre um historiador e um sociólogo, para construir uma breve história da técnica; na segunda seção apresentarei um diálogo sobre o conceito de alienação entre Marx e (...) Heidegger a partir do pensamento do filósofo venezuelano Mayz Vallenilla e na última seção apresentarei a conexão entre ética e meta-técnica como alternativa atraente à alienação técnica. (shrink)

I present different approaches to psychological causality usually neglected. The debate between mechanism and dualism in psychology has obscured other pluralistic philosophical positions. I begin by setting out Schopenhauer’s position, the "analogic" one, which includes, in a pluralistic view, diverse causations (mechanical, stimulate, and motive reasons) but with a monism of the will at the noumenal level. Then, I review other approaches in psychology and biological sciences: dialectical, constructivist and biosemiotics. All agree to see reality as plural and self-constituted. En (...) este trabajo presento distintos enfoques sobre la causalidad psicológica normalmente desatendidos. El debate entre mecanicismo y dualismo en la psicología ha oscurecido otras posiciones filosóficas pluralistas. Comienzo por exponer la postura "analógica" de Schopenhauer, que incluye -de forma pluralista- una diversidad de causaciones (mecánica, estimular y causalidad por motivos) pero con un monismo de la voluntad en el plano nouménico. Después reviso otros enfoques dialécticos en la psicología y en las ciencias biológicas: dialécticas, constructivistas y biosemióticas. Todos ellos coinciden en ver la realidad como plural y autoconstituida. (shrink)

We attempt a review to several currents that, nowadays, are self-claimed "constructivists", inside of a biological overview of knowledge. We’ll try to throw some light about the question: are all of them a very alternative to realism? If they are in opposition of realism, or they are antipoda..

El presente texto es un primer acercamiento a la tensión entre las necesidades y preferencias, a partir de dos pensadores significativos para la Teoría Crítica. Herbert Marcuse, miembro de la primera generación de la Escuela de Frankfurt, y Franz Hinkelammert, referente de una renovada Teoría Crítica nacida y continuada creativamente en América Latina. Pensadores que darán elementos esclarecedores para profundizar una problemática que nos preocupa hace tiempo: la cooptación de los deseos y su metamorfosis en necesidades como mecanismo de dominación (...) que opera, no ya en la conciencia sino en la misma sensibilidad humana.

El objetivo fue analizar la adquisición de vocabulario en idioma inglés de estudiantes de bachillerato a partir de la implementación de actividades de resolución de problemas. Se empleó un diseño cuasiexperimental de pre y post test, con grupo experimental y control. Los resultados sugieren que las actividades de resolución de problemas son estrategias didácticas efectivas para la enseñanza del inglés.

The origin of Being as a live concept is one of the most difficult questions in history of metaphysics and ontology. This work analyses the postulate that being is constructed by the interaction of terms. In fact, being and the idea of Being has come from the possibility of relations. It is known that metaphysics and ontology has overestimated think Being like something that never change, a substance unchangeable. Reduce Being as ousía, translated as substance, does not understand central affirmation (...) of Aristotle that “The term “being” is used in various senses, but with reference to one central idea and one definite characteristic, and not as merely a common epithet.”. The usually interpretation of relations make them one of those ways, however the concept of Being is always under a relation. Is reconsidered the role of relations in the basis of ontological thinking, taking the renewal of metaphysics, of the French philosopher Jean Wahl, and postulating that Being as totality is the relation that involves beings, Change and Time.

In futsal there are two referees on the playing court and their capacity to respond to physical and physiological demands imposed during the game is essential for the success. The futsal characteristics such as size pitch, referees position and rules of games or type of league could impose specific physical efforts probably. The aim of this study were to analyze the physical demands of eight elite referees from seven matches of Spanish Futsal Cup 2020. The physical activity of each referee (...) during the match was monitored with a Local Positioning System, which was installed on futsal pitch where the matches were played. The data differences were evaluated as Paired-Samples T-Test procedure. The results revealed a similar total distance between halves. The zone 3 distance showed a significative decrease during the match in comparison to the first and second halves. The number of high-intensity acceleration and deceleration decreased in the second half of the match. Therefore, the use of the tracking device to monitoring physical performance provides knowledge of the specific activity profile from futsal referees. This information to can be useful to design more accurate the training programs. (shrink)

In the second half of the 20th century, Latin American poetry has had to deal with representing the phenomenon of forced disappearance in its various poetic productions. Some of those have incubated in the Central American civil wars, the dictatorial regimes of the Southern Cone and even in countries with supposed democratic stability such as Mexico and Colombia. Memorial de Ayotzinapa, by the Mexican poet Mario Bojórquez, and Carta de las mujeres de este país, by the Colombian poet and activist (...) Fredy Yezzed, experiment with the discursive forms of the long poem and the letter poem, respectively, to construct collective memories around a phenomenon that continues to take lives to this day. Bojórquez's text is concerned with constructing a testimony, apparently in situ, of the disappearance of the forty-three Mexican teacher trainees; Yezzed's work, for its part, refrains from referring to a specific event or place in order to provide a more complete testimony of the Colombian armed conflict, nearly seventy years old. The article analyzes the forms of the text, the subjects and their spaces of enunciation, as well as the memory strategies that are seen in both works. Thus, the testimonial status of poetry is confirmed, sometimes overshadowed by genres such as the novel and the short story. (shrink)

Si no me falla la memoria, fue el dibujante Álvaro Barrios quien afirmó que el trabajo del artista contemporáneo colombiano se desarrolla según una agenda de trabajo. Si miramos algunos fenómenos del arte último en Colombia, podemos señalar que su agenda está determinada por el intento de comprensión de los procesos de la violencia en el país, a partir de una amplia gama de aproximaciones al concepto de memoria que ha tenido resonancia en las disciplinas humanísticas, las investigaciones académicas, el (...) uso político del concepto por parte de la legislación estatal, y una gran diversidad de eventos artísticos. Desde el ámbito del arte, exposiciones como Destierro y reparación (2008), Tapices de Mampuján (2010), La guerra que no hemos visto (2009) o La piel de la memoria (2011), han discutido sobre la violencia en Colombia desde la aproximación a los procesos de comprensión de la memoria y nuestro pasado reciente. Así, la imbricación de violencia y memoria se manifiesta en la visión del pasado y en los efectos que este puede desplegar sobre el presente, en tanto se ha considerado, incluso, a la memoria como una instancia de reconciliación social.

Citizenship as status implies the acknowledgment of individual rights as well as social ones. This very acceptance requires the consideration of all citizens as equal despite any personal difference and it represents an aim that is mostly dependent on the mass-media social function. The formal acknowledgment of the citizenship would be scarcely important if identity stereotypes and prejudice-based discrimination occurred during citizen's vital happenings. Today, citizenship must include the communicative dimension as part of the social integration project. Societies are every (...) day more intercultural, and media play an essential role in representing the other. As part of a Grundtvig project on intercultural education, the author conducted an experience with journalistic ethics students of the Communication School at the University of Seville. From this experience, the author reflects on multiculturalism as a necessary tool in the training of future journalists. (shrink)

In this paper we study the axiomatic system proposed by Bourbaki for the Theory of Sets in the Éléments de Mathématique. We begin by examining the role played by the sign \(\uptau \) in the framework of its formal logical theory and then we show that the system of axioms for set theory is equivalent to Zermelo–Fraenkel system with the axiom of choice but without the axiom of foundation. Moreover, we study Grothendieck’s proposal of adding to Bourbaki’s system the axiom (...) of universes for the purpose of considering the theory of categories. In this regard, we make some historical and epistemological remarks that could explain the conservative attitude of the Group. (shrink)

According to a growing body of studies, people’s ability to forecast future emotional experiences is generally biased. Nonetheless, the existing literature has mainly explored affective forecasting in relation to specific events, whereas little is still known about the ability to make general estimations of future emotional states. Based on existing evidence suggesting future-oriented disposition as a key factor for mental health, the aims of the current study were (1) to investigate the relationship between negative (NA) and positive (PA) affective forecasting (...) biases and perceived psychological well-being, and (2) to explore whether positively biased predictions are associated with resilience and foster one’s skills to cope with stressful events. To do so, we asked 85 undergraduate students to forecast PA and NA over two weeks, as well as to report their daily affect through a web-based Ecological Momentary Assessment. According to the results, positively biased PA forecasting (i.e., overestimating positive emotional states) was associated with greater perceived psychological well-being and higher resilience. When high levels of stress were experienced, participants holding an optimistic, yet biased, estimation of future PA were more likely to successfully manage stressors, thus maintaining lower levels of NA and higher levels of positive emotions. We suggest that positively biased PA forecasting is an adaptive cognitive distortion that boosts people’s resilience and mental health, thus opening new avenues for the promotion of psychological well-being.

This article studies natural food packaging as enabling artifacts of the traditional material culture of Antioquia in Colombia. For this purpose, we consider artifacts as objective nodes that combine design and use intentions, functions, materials, histories, artifactual lineages, and cooperative relationships that stabilize ritualized practices of a human group. We take the example of natural packaging as artifacts that enablers and stabilizers of traditional cooking and food preparation practices. Natural packaging materials are here assumed to be leaves having some favorable (...) property to contain a food product. After providing a theoretical reflection, we analyze the data collected from fieldwork we conducted in two towns in Antioquia, Colombia (Santa Fe de Antioquia and Amagá), as well as from an interview with an expert in the field. Finally, we show that it is possible to postulate an analysis under a relational ontological description of a traditional practice with conceptual categories of the philosophy of technology.

The knowledge extraction from data with noise or outliers is a complex problem in the data mining area. Normally, it is not easy to eliminate those problematic instances. To obtain information from this type of data, robust classifiers are the best option to use. One of them is the application of bagging scheme on weak single classifiers. The Credal C4.5 model is a new classification tree procedure based on the classical C4.5 algorithm and imprecise probabilities. It represents a type of (...) the so-calledcredal trees. It has been proven that CC4.5 is more robust to noise than C4.5 method and even than other previous credal tree models. In this paper, the performance of the CC4.5 model in bagging schemes on noisy domains is shown. An experimental study on data sets with added noise is carried out in order to compare results where bagging schemes are applied on credal trees and C4.5 procedure. As a benchmark point, the known Random Forest classification method is also used. It will be shown that the bagging ensemble using pruned credal trees outperforms the successful bagging C4.5 and RF when data sets with medium-to-high noise level are classified. (shrink)

The emergent Coronavirus Disease 2019 caused by the Severe Acute Respiratory Syndrome Coronavirus 2 could produce a maternal immune activation via the inflammatory response during gestation that may impair fetal neurodevelopment and lead to postnatal and adulthood mental illness and behavioral dysfunctions. However, so far, limited evidence exists regarding long-term physiological, immunological, and neurodevelopmental modifications produced by the SARS-CoV-2 in the human maternal-fetal binomial and, particularly, in the offspring. Relevant findings derived from epidemiological and preclinical models show that a MIA (...) is indeed linked to an increased risk of neurodevelopmental disorders in the offspring. We hypothesize that a gestational infection triggered by SARS-CoV-2 increases the risks leading to neurodevelopmental disorders of the newborn, which can affect childhood and the long-term quality of life. In particular, disruption of either the maternal or the fetal cholinergic anti-inflammatory pathway could cause or exacerbate the severity of COVID-19 in the maternal-fetal binomial. From a translational perspective, in this paper, we discuss the possible manifestation of a MIA by SARS-CoV-2 and the subsequent neurodevelopmental disorders considering the role of the fetal-maternal cytokine cross-talk and the CAP. Specifically, we highlight the urgent need of preclinical studies as well as multicenter and international databanks of maternal-fetal psychophysiological data obtained pre-, during, and post-infection by SARS-CoV-2 from pregnant women and their offspring.

The progress of Mathematics during the nineteenth century was characterised both by an enormous acquisition of new knowledge and by the attempts to introduce rigour in reasoning patterns and mathematical writing. Cauchy’s presentation of Mathematical Analysis was not immediately accepted, and many writers, though aware of that new style, did not use it in their own mathematical production. This paper is devoted to an episode of this sort that took place in Spain during the first half of the century: It (...) deals with the presentation of a method for numerically solving algebraic equations by José Mariano Vallejo, a late Spanish follower of the Enlightenment ideas, politician, writer, and mathematician who published it in the fourth (1840) edition of his book Compendio de Matemáticas Puras y Mistas, claiming to have discovered it on his own. Vallejo’s main achievement was to write down the whole procedure in a very careful way taking into account the different types of roots, although he paid little attention to questions such as convergence checks and the fulfilment of the hypotheses of Rolle’s Theorem. For sure this lack of mathematical care prevented Vallejo to occupy a place among the forerunners of Computational Algebra. (shrink)

Este nuevo volumen de "Estudios Interdisciplinares" reúne diversas reflexiones que abordan el problema de lo natural y de lo artificial en el marco de la cultura humana. Lo natural y lo artificial son siempre parte de la naturaleza real. Pero la acción humana debe ser creadora de cultura y, por ello, tanto su vinculación a la naturaleza como su acción creadora de un mundo de artefactos posibles deben estar siempre al servicio de la especie humana, es decir, al servicio de (...) la calidad existencial y de la dignidad del hombre.

Aberrations introduced by the atmospheric turbulence in large telescopes are compensated using adaptive optics systems, where the use of deformable mirrors and multiple sensors relies on complex control systems. Recently, the development of larger scales of telescopes as the E-ELT or TMT has created a computational challenge due to the increasing complexity of the new adaptive optics systems. The Complex Atmospheric Reconstructor based on Machine Learning is an algorithm based on artificial neural networks, designed to compensate the atmospheric turbulence. During (...) recent years, the use of GPUs has been proved to be a great solution to speed up the learning process of neural networks, and different frameworks have been created to ease their development. The implementation of CARMEN in different Multi-GPU frameworks is presented in this paper, along with its development in a language originally developed for GPU, like CUDA. This implementation offers the best response for all the presented cases, although its advantage of using more than one GPU occurs only in large networks. (shrink)

Our work aimed to study the relationships between different dimensions of school climate, moral disengagement, empathy, and bullying behaviors (perpetration and victimization). The study sample consisted of 629 students (304 boys and 325 girls) aged 12–14 years (M= 12.55,SD= 0.67). Results showed how different dimensions of school climate predicted moral disengagement, empathy, and victimization, and these, in turn, predicted bullying perpetration. The results show the need to generate favorable educational environments to reduce the levels of moral disengagement and victimization and (...) to increase empathy in students as a strategy to prevent negative consequences related to bullying.

With the advent of the cloud computing model allowing a shared access to massive computing facilities, a surging demand emerges for the protection of the intellectual property tied to the programs executed on these uncontrolled systems. If novel paradigm as confidential computing aims at protecting the data manipulated during the execution, obfuscating techniques (in particular at the source code level) remain a popular solution to conceal the purpose of a program or its logic without altering its functionality, thus preventing reverse-engineering (...) on the program even with the help of computing resources. The many advantages of code obfuscation, together with its low cost, makes it a popular technique. This paper proposes a novel methodology for source code obfuscation that can be used together with other traditional obfuscation techniques, making the code more robust against reverse engineering attacks. Three program complexity metrics are used to define three different single-objective combinatorial optimization versions of the problem, which are solved and analysed. Additionally, three multi-objective problems are defined, those considering each of the selected metrics together with the program execution time, in order to avoid strong obfuscations penalizing the performance. The goal of the defined problems is to find sequences of LLVM optimizations that lead to highly obfuscated versions of the original code. These transformations are applied to the back-end pseudo-assembly code (i.e., LLVM Intermediate Representation), thus avoiding any further optimizations by the compiler. Classical genetic algorithms (GAs) are used to solve the studied problems, namely a basic cellular GA for the single-objective problems and the popular NSGA-II for the multi-objective ones. The promising results show the potential of the proposed technique. (shrink)

An experimental study was designed to analyze the effect of school-based training in self-regulation learning strategies on academic performance. Class-level variables were considered and the effects of the intervention were measured at the end of the intervention and 3 months later. A sample of 761 students from 3rd and 4th grades, from 14 schools, participated in the study. Data were analyzed using three-level analysis with within-student measurements at level 1, between-students within-classes at level 2, and between-classes at level 3. Data (...) showed a positive effect of the intervention on student performance, both at post-test and at follow-up considering the four school subjects together. However, the effect was significant just at follow-up when subjects were considered separately. Student performance was significantly related to the students’ variables and the context. Finally, students’ gender and level of reading comprehension, as well as the teacher’s gender, were found to moderate the effect of the intervention on students’ academic performance. Two conclusions were highlighted: first, data emphasize the importance of considering time while conducting intervention studies. Second, more teaching experience does not necessarily translate into improvements in the quality of students’ instruction. (shrink)

Alasdair MacIntyre´s criticism of Modernity essentially refers to the problem of compartmentalization, which restricts the possibility of achieving excellence in an integral lifestyle. Among other reasons, compartmentalization is especially derived from an insular valorization of the workplace based on a reductionist understanding of productivity in terms of mere efficiency. Aimed at overcoming the moral confusion derived from the overestimation of technical, skilled productivity and individualistic cooperation in private corporations, this article offers a thicker explanation of MacIntyre’s theory of productive work (...) in light of a narrative approach that opens up the possibility of achieving standards of excellence in modern production. To do so, it follows MacIntyre’s understanding of productivity in terms of craftsmanship by explaining what excellence in production is and the role it plays in achieving unity of life and excellence in modern corporations based on two criteria derived from a historical definition of production, namely, craftsmanship and collegiality.

Most formalisms for representing common-sense knowledge allow incomplete and potentially inconsistent information. When strong negation is also allowed, contradictory conclusions can arise. A criterion for deciding between them is needed. The aim of this paper is to investigate an inherent and autonomous comparison criterion, based on specificity as defined in [POO 85, SIM 92]. In contrast to other approaches, we consider not only defeasible, but also strict knowledge. Our criterion is context-sensitive, i. e., preference among defeasible rules is determined dynamically (...) during the dialectical analysis.We show how specificity can be defined in terms of two different approaches: activation sets and derivation trees. This allows us to get a syntactic criterion that can be implemented in a computationally attractive way. The resulting definitions may be applied in general rulebased formalisms. We present theorems linking both characterizations. Finally we discuss other frameworks for defeasible reasoning in which preference handling is considered explicitly. (shrink)
