Hoy nos movemos en un mundo altamente cambiante y atestado de desarrollo científico, técnico y tecnológico. Un mundo condicionado por los intereses de una globalización económica, donde el imperativo es consumir, y donde aquellos que producen de manera individual y distinta son absorbidos, en el mejor de los casos, o anulados por el sistema capitalista. Ahora bien, ese estado de cosas ha puesto en riesgo de pérdida al sujeto racional heredado y caracterizado desde la modernidad y que es requerido hoy (...) día como sujeto de racionalidad tecnológica. El sujeto-persona-agente racional se encuentra en una encrucijada ante la sociedad de consumo y el sistema económico de producción. La encrucijada consiste en si sigue aceptando el ser considerado y utilizado como un objeto, cosa, instrumento, artefacto más dentro del sistema artefactual o recobrar la capacidad de racionalidad, heredada desde la Modernidad y refrendada como racionalidad tecnológica desde la Revolución Industrial.

This article examines the Kantian ideas on motion in his work Metaphysical Foundations of Natural Science. In that essay, Kant holds that motion as a concept—from its connotation as elemental and fundamental predicament of the material reality—mobilises in matter all the characteristics of its essence as a property. Nevertheless conceiving motion as a concept does not enable us to confirm the existence of motion itself in the natural world because ‘the possibility of specific natural things can’t be discovered from their (...) mere concepts.’. Therefore, the concept of movement does not evidence the existence of the movement or its characteristics and properties. Such claim would imply that motion as a concept is not evidence of the existence of motion as such and, therefore, the properties of matter cannot be mobilised based on that concept because they are characteristics of the essence of motion. Then, how does Kant intend to denote motion? Why pretend to explain matter form the concept of motion if a pure concept is, by definition, independent of the data obtained from the sensibility?. Therefore, we will demonstrate that such weakness is the breaking point of the Kantian concept of motion in his “dynamic-metaphysical” model. (shrink)

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)

From an early age, exposure to a spoken language has allowed us to implicitly capture the structure underlying the succession of speech sounds in that language and to segment it into meaningful units. Statistical learning, the ability to pick up patterns in the sensory environment without intention or reinforcement, is thus assumed to play a central role in the acquisition of the rule-governed aspects of language, including the discovery of word boundaries in the continuous acoustic stream. Although extensive evidence has (...) been gathered from artificial languages experiments showing that children and adults are able to track the regularities embedded in the auditory input, as the probability of one syllable to follow another syllable in the speech stream, the developmental trajectory of this ability remains controversial. In this work, we have collected Event-Related Potentials while 5-year-old children and young adults were exposed to a speech stream made of the repetition of eight three-syllable nonsense words presenting different levels of predictability to mimic closely what occurs in natural languages and to get new insights into the changes that the mechanisms underlying auditory statistical learning might undergo through the development. The participants performed the aSL task first under implicit and, subsequently, under explicit conditions to further analyze if children take advantage of previous knowledge of the to-be-learned regularities to enhance SL, as observed with the adult participants. These findings would also contribute to extend our knowledge of the mechanisms available to assist SL at each developmental stage. Although behavioral signs of learning, even under explicit conditions, were only observed for the adult participants, ERP data showed evidence of online segmentation in the brain in both groups, as indexed by modulations in the N100 and N400 components. A detailed analysis of the neural data suggests, however, that adults and children rely on different mechanisms to assist the extraction of word-like units from the continuous speech stream, hence supporting the view that SL with auditory linguistic materials changes through development.

Fibromyalgia is a chronic pain syndrome characterized by dysfunctional processing of nociceptive stimulation. Neuroimaging studies have pointed out that pain-related network functioning seems to be altered in these patients. It is thought that this clinical symptomatology may be maintained or even strengthened because of an enhanced expectancy for painful stimuli or its forthcoming appearance. However, neural electrophysiological correlates associated with such attentional mechanisms have been scarcely explored. In the current study, expectancy processes of upcoming laser stimulation (painful and non-painful) and (...) its further processing were explored by event-related potentials (ERPs). Nineteen fibromyalgia patients and twenty healthy control volunteers took part in the experiment. Behavioral measures (reaction times and subjective pain perception) were also collected. We manipulated the pain/no pain expectancy through an S1–S2 paradigm (cue-target). S1 (image: triangle or square) predicted the S2 appearance (laser stimulation: warmth or pinprick sensation). Laser stimuli were delivered using a CO2 laser device. Temporal and spatial principal component analyses were employed to define and quantify the ERP component reliability. Statistical analyses revealed the existence of an abnormal pattern of pain expectancy in patients with fibromyalgia. Specifically, our results showed attenuated amplitudes at posterior lCNV component in anticipation of painful stimulation that was not found in healthy participants. In contrast, although larger P2 amplitudes to painful compared to innocuous events were shown, patients did not show any amplitude change in this laser-evoked response as a function of pain predictive cues (as occurred in the healthy control group). Additionally, analyses of the subjective perception of pain and reaction time indicated that laser stimuli preceded by pain cues were rated as more painful than those signaling non-pain expectancy and were associated with faster responses. Differences between groups were not found. The present findings suggest the presence of dysfunction in pain expectation mechanisms in fibromyalgia that eventually may make it difficult for patients to correctly interpret signs that prevent pain symptoms. Furthermore, the abnormal pattern in pain expectancy displayed by fibromyalgia patients could result in ineffective pain coping strategies. Understanding the neural correlates of pain processing and its modulatory factors is crucial to identify treatments for chronic pain syndromes. (shrink)

Edición a cargo de José Luis Tasset & Francisco Vázquez García. Introducción de José Luis Tasset. Epílogo de Francisco Vázquez García.

Aristotelian virtue is the source of the soul’s best actions and passions. It can compel us to do the best acts and doings, always in a better way. Aristotelian virtue helps us to act under the right reasoning, which is elected from an intellectual disposition called prudence, which is in charge of uniting knowledge and action. Aristotle says one can learn to be virtuous through exercising good habits, with formation, experience and time to do such an exercise. Besides, actions according (...) to virtue will be nice by themselves, if a virtuous man judges righteously. This is precisely the root of good living and good acting for Aristotle. The activities performed by a good man are, then and by themselves, good, nice and happy, and are also related to virtue and to the actions of a virtuous man. This paper aims at analyzing virtue as a pathway to happiness, the actions to achieve it and to describe some intellectual and moral virtues established within the moral philosophy of this thinker.

Among various issues that concern human beings, there are a few that are of current interest and have really grabbed our attention: love for nature, environmental defense, and worries about Biodiversity and Biosecurity. The article considers one particular aspect regarding the bioethical concern of using animals in experiments that might benefit both humans and animals. The problematic aspect of the bioethical use of animals in scientific experimentation has been and will remain crucial for human life. Additionally, the results of this (...) type of research could contribute to animal welfare, which have an impact on public health. (shrink)

Animals have made possible to science the production of new knowledge within the fields of Biology and Physiology. This knowledge has allowed the development of methods of diagnosis and treatments that improve the quality of life of human beings and animals. Therefore, the use of animals for testing should be made with respect, and considering the possible reactions of the animals and their own ethology. Animal testing might remain under debate in the coming years due to the necessity to adapt (...) the care of the animals used for testing to the opportunities and challenges that might come in the future. Thus, it will be relevant for researchers to remain up to date with the progress of procedures. Bearing all this in mind, it is necessary to examine the ethical appropriateness of the legal aspects considered by Colombian regulations concerning scientific experimentation and testing. Such aspects are discussed in the article and a proposal for a National Legislation that takes into account all the technical, scientific and bioethical elements that are involved in animal testing is outlined.

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

Esta obra se concentra en cuatro temas cruciales de la formación de docentes, tanto antes como durante el servicio y en la enseñanza en diferentes áreas y niveles educativos. En primer lugar, se aborda el asunto de las creencias que los docentes tienen sobre el proceso educativo, las cuales parecen influir en la práctica profesional que estos desarrollan y, por lo tanto, deberían recibir la atención explícita de los procesos de formación de docentes que deseen promover prácticas específicas. El segundo (...) tema de la obra es la relación entre la formación de docentes y la política pública que la rige. En particular, se analizan las reformas curriculares implementadas por varias licenciaturas en universidades privadas colombianas, en respuesta a reformas a la normatividad sobre las condiciones de calidad que a las que deben ajustarse todas las licenciaturas del país. El tercer tema analizado es en qué medida los docentes en educación superior van más allá del dominio de su saber disciplinar atribuyendo importancia a la pedagogía, la didáctica y la práctica reflexiva en su propia práctica docente. Finalmente, se discuten aspectos de la formación de docentes relacionados con los procesos vividos y los retos encontrados por los docentes al entrar en la profesión, su socialización en la comunidad docente, sus identidades como maestros y su motivación para ser docentes. Vale la pena señalar que las contribuciones a este libro comparten el uso de metodologías cualitativas y presentan los resultados de historias de vida, entrevistas, observaciones, y análisis documentales, entre otros.

La vulnerabilidad narrativa, producto de la exclusión de los marcos de representación del contexto, que priva a algunos de ser vistos, escuchados y sentidos por la mayoría, implica la precariedad de amplias generaciones transformadas en “vidas fungibles”, esto es, en instrumentos vivos y animados de las máquinas de la guerra. Estos hombres y mujeres, empero, no son engranajes de la destrucción, sino seres con un nombre y una historia singular. Su capacidad de traducir narrativamente la realidad ofrece otro encuadre de (...) interpretación sobre el pasado y el futuro a partir de su llamado a una nueva vida y al fin de la violencia armada. Aquí reside la propuesta de esta contribución, en la que, usando las reflexiones de Hannah Arendt y de Judith Butler, además de una entrevista a profundidad con un excombatiente colombiano en proceso de reintegración, se advierte en la narración la respuesta a la fungibilidad —‍ la condición de existencias usufructuables, reemplazables y matables‍‍— de forma que se posibilita una vida biográfica, cargada de porvenir.

The objective of this work is to show that the cognitive and ontological connections between Benjamin’s and Zambrano’s works, more than similarities and differences, are based on the exercise of their expressive action. Along with the image that appears in the writing, both thinkers cite old poetic forms, which allows them to update philosophical, political and theological figurations to configure an experience of thinking in work.

The development of science has produced a gap between the knowledge accepted by scientific communities and popular beliefs. This subject has worried scientists, considering that many of these beliefs turn out to be untenable. In addition to the problems related to education and scientific dissemination, the study of folk beliefs raises intriguing questions for epistemology and cognitive sciences about the processes of formation and justification of knowledge. This theme also has important repercussions in terms of actions, based on the fact (...) that folk beliefs can motivate wrong decisions. The objective of this article is to analyze the folk beliefs related to the economic field, showing some of its possible causes and some consequences regading decision making. (shrink)

El objetivo del presente trabajo es mostrar que las conexiones cognoscitivas y ontológicas entre Benjamin y Zambrano, más que simples similitudes y diferencias, se fundamentan en el ejercicio mismo de su acción expresiva. Junto a la imagen que brinca en la escritura, ambos pensadores citan viejas formas poéticas, permitiéndoles actualizar figuraciones filosóficas, políticas y teológicas para configurar una experiencia del pensar en obra.

Discovering the influences between paintings and artists is very important for automatic art analysis. Lately, this problem has gained more importance since research studies are looking into explanations about the origin and evolution of artistic styles, which is a related problem. This paper proposes to build a multiplex artwork representation based on artistic formal concepts to gain more understanding about the aforementioned problem. We complement and built our approach on the previous notion of Creativity Implication Network. We used the recently (...) proposed MultiRank algorithm to suggest possible explanations of the dynamic of some artistic styles. Our results corroborate some well-known facts about the artists analyzed and give qualitative and quantitative information that show the possibilities and strengths of the proposed framework. We plan to expand our analysis to include more abstract artworks. Ideally, we are going to be able to validate more our results and test how our methodology could be used to generate visual artifacts too. (shrink)

Reseña sobre el libro La técnica del capital. Ensayos sobre Bolívar Echeverría y Karl Marx, de Andrea Torres Gaxiola.

Este artigo não pretende analisar o conjunto da obra de Habermas. Trata-se de pensar exclusivamente a Teoria da Ação Comunicativa, primeiro, em relação aos teóricos em que afirma fundamentar-se, depois, no sentido da sua própria articulação lógica interna e, finalmente, em relação ao seu objeto de pesquisa, a realidade social. Procura demonstrar que a TAC executa dois giros conceituais essenciais: um ao limitar o agir estratégico ao espaço da economia e da política e outro ao definir cultura, sociabilidade e subjetividade (...) como dimensões constituídas no mundo da vida.

The environmental damage that has been generated by human activity is a cause for concern, so pro-environmental behavior has been identified as one of the possible solutions. However, it has been seen that there are psychological barriers that prevent or hinder this behavior. For this reason, in order to have an instrument to evaluate these psychological barriers in our context, the objective of this research was to adapt the Dragons of Inaction Psychological Barriers scale to the Colombian population. The sample (...) was made up of 810 university students from Bogotá and Chía, Colombia; 367 males and 443 females between 15 and 48 years of age. In general, an exploratory factor analysis and a confirmatory factor analysis were carried out, which demonstrated the existence of a five-factor structure with 20 items. Item and reliability analyses were performed, which demonstrated that the instrument has a high internal consistency; and two invariance studies were carried out, which showed that the factor structure is invariant for all study groups. In addition, the total instrument was scored. In conclusion, this adaptation of the DIPB presents adequate validity and reliability, and allows guiding future research on inaction barriers in the Latin American context, while providing an input for a first diagnosis of this construct in Colombia.

Resumen: El objetivo del presente escrito es analizar una confusión epistemológica recurrente en algunas corrientes filosóficas contemporáneas: el sociologismo, que consiste en establecer juicios acerca de la justificación de la ciencia a partir de sus orígenes históricos. En particular, me interesa revisar sus variantes relativistas, que, en sus formas más radicales, llegan a identificar la pretensión de racionalidad y objetividad de la ciencia con los mecanismos de poder. Mediante el análisis argumentativo, mostraré los errores en los que incurren estas vertientes.: (...)

Na atualidade estamos enfrentando uma forte onda de intolerância e tolerância, potencializando e valorizando a Tolerância como sendo um modelo a seguir, e seria a solução para as fortes condutas violentas, discriminatórias e criminosas que estamos sendo vítimas nas relações interpessoais e nas relações entre culturas e países. Tolerar o desigual, o assimétrico é uma luta desigual, do mais forte contra aquele que pela sua realidade social, tem sido enfraquecido. Como formar uma consciência e uma cultura, não do tolerar-aguentar a (...) partir de minhas condições impostas; mas uma cultura de hospitalidade, de acolhida, de abertura ao distante, ao assimétrico e estranho. A hospitalidade incondicional, ou seja, não coloco nenhuma condição, a única condição para acolher ao estrangeiro que chega do além do horizonte, é não ter condições. Desse modo não acolho uma categoria estrangeiro, mas uma pessoa que tem sua individualidade e sua unicidade. Para uma acolhida com hospitalidade é necessário criar um deslocamento na minha interioridade, me acomodar diferente, o outro que chega sempre provoca um movimento interior e exterior no meu eu; quando não acolho ao assimétrico, colocando condições na sua chegada, nada de novo acontece no eu. Acolher com hospitalidade é a possibilidade de nos experimentar diferente e de inaugurar algo novo em nós, na construção de sermos cada vez melhores, mais humanos, solidários e hospitaleiros. Palavras-chave: Tolerância, Intolerância, Hospitalidade condicional, Hospitalidade incondicional, Estrangeiro. (shrink)

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.

Neste artigo analisaremos como a filosofia de Charles Sanders Peirce influencia o pensamento de Karl-Otto Apel na elaboração da sua ética do discurso. Pretendemos mostrar que Apel compreende que Peirce elabora uma transformação da filosofia transcendental kantiana, substituindo o “eu penso” por um “eu argumento”, neste viés Peirce demonstrou a existência de um acordo mútuo intersubjetivo dentro da comunidade científica. Sendo que, este acordo é mediado pela linguagem, e se dá em função da garantia da verdade das proposições. Conclui-se que (...) Apel ver em Peirce a introdução de uma ética mínima que supera o solipsismo metódico, e se baseia na intersubjetividade, tornando possível um acordo mútuo, que mais tarde será a base para a fundamentação pragmático-transcendental da ética do discurso.

Determined to fight alone, stripped from the security that could be offered by community, human beings of our times have openly embraced their individuality. With such a purpose, consciously or unconsciously, they have decided to decimate the institutions and to break with the burden imposed by rules, laws and agreements, which they consider are oppressive and limit their personal development. Thus, the article offers a philosophical review of the concept of community and examines the necessity of its reconfiguration as social (...) linking force. This arises as an answer to possible risks associated with the coming of a new individual that adopts her selfhood as the only truth, which leads to not acknowledging otherness and plurality, and to individualism as the only possible way of being.

Nowadays, batteries play an important role in a lot of different applications like energy storage, electro-mobility, consumer electronic and so on. All the battery types have a common factor that is their complexity, independently of its nature. Usually, the batteries have an electrochemical nature. Several different test are accomplished to check the batteries performance, and commonly, it is predictable how they work depending of their technology. The present research describes the hybrid intelligent system created to accomplish fault detection over a (...) Lithium Iron Phosphate—LiFePO4 power cell type, commonly used in electro-mobility applications. The approach is based on the cell temperatures behaviour for voltage and current specific values. Taken into account the operating range of a real system based on a LiFePO4 cell, a large set of points of operation have been used to achieve the dataset. The different behaviour zones have been obtained by clustering as a first step. Then, different regression techniques have been used over each cluster. Polynomial regression, artificial neural networks and support vector regression were the combined techniques to develop the hybrid intelligent model proposed. The intelligent system gives very good results over the operating range, detecting all the faults tested during the validation. (shrink)
