El Rey de la Habana es la metáfora trágica del agotamiento de la Cuba castrista y el tortuoso parto de una nueva realidad social que no acaba de nacer. En las prietas páginas de una breve novela, repletas de violencia, bestialidad, sexo desaforado, heces y descarnada lucha por la vida, Pedro Juan Gutiérrez se erige como testigo de su época y el destino de su patria. Su telón de fondo es una Habana decadente, físicamente carcomida, donde el (...) “sálvese cada uno como pueda” funciona como ley social. Esta obra coloca a su autor entre los novelistas latinoamericanos medulares en la bisagra entre el s. XX y el s. XXI. (shrink)

The Cybersyn project has lately received increased attention. In this article, we study the local technical antecedents of Stafford Beer's Cybersyn project in Chile, particularly regarding Cybernetics and Systems ideas and local computing and networking developments. We show that the Cybersyn project in Chile was hosted by a rich intellectual environment that understood Cybernetics and Systems ideas; that it found a mature computer community and infrastructure whose high point was the State Computing Enterprise EMCO/ECOM, and an advanced networking experience whose (...) flagship was the automation of the State Bank that involved a pioneering network of teleprocess. In summary, this paper attempts to unveil the deep historical background over which the globally unique cybernetic experiment called Cybersyn flourished. (shrink)

El presente trabajo hace un análisis de la corta narración “decisión ante el trapecio”, escrita por el autor con motivo de la vida y obra del novelista Franz Kafka. Con ello se invita al lector ha reconocer en la aplicación del método (o enfoque) fenomenológico del “Análisis reflexivo”, una herramienta conceptual importante para lograr una mejor comprensión de las relaciones entre el arte y la filosofía. La soledad, el solipsismo y obviamente “las relaciones con el Otro”, son temas recurrentes tanto (...) a la literatura como a la fenomenología de Husserl, y por este motivo se propone el análisis partiendo de la narración literaria.

En primera instancia a modo de preámbulo el autor hace una semblanza de la vida de Julia Iribarne en la cual rememora algunos encuentros con la autora en sus visitas académicas a Colombia. Luego se plantea algunos temas con respecto al fluir de la conciencia en la experiencia, y la constitución de la identidad personal. Este tema tiene de trasfondo el problema de la experiencia humana del tiempo y de la constitución fenomenológica de la conciencia interna del tiempo. La hipótesis (...) que desarrolla siguiendo a la autora tiene que ver con la posibilidad de mostrar como el fluir originario del presente viviente, es condición necesaria pero no suficiente para el desarrollo de la persona y de su identidad.First of all, as a foreword, the author makes a portrait of Julia Iribarne’s life, in which he remembers the time when she visited Colombia for academical reasons. Then he considers some topics in regard of the flowing of consciousness into experience concerning the forming of an individual’s personal identity. This topic has, as a background, the problem of the human experience of time and the phenomenological constitution of the internal consciousness of time. The hypothesis that it develops, following her, has to do with the possibility of showing how the original flowing of the living present is a required condition, but not enough, for the development of a person and his or her own identity.

A pre-experiment was applied which allowed to test the effectiveness of these tasks. This proposal favored the relation between the school and the community taking into account the environmental protection. (shrink)

The area of smart power grids needs to constantly improve its efficiency and resilience, to provide high quality electrical power in a resilient grid, while managing faults and avoiding failures. Achieving this requires high component reliability, adequate maintenance, and a studied failure occurrence. Correct system operation involves those activities and novel methodologies to detect, classify, and isolate faults and failures and model and simulate processes with predictive algorithms and analytics. In this paper, we showcase the application of a complex-adaptive, self-organizing (...) modeling method, and Probabilistic Boolean Networks, as a way towards the understanding of the dynamics of smart grid devices, and to model and characterize their behavior. This work demonstrates that PBNs are equivalent to the standard Reinforcement Learning Cycle, in which the agent/model has an interaction with its environment and receives feedback from it in the form of a reward signal. Different reward structures were created to characterize preferred behavior. This information can be used to guide the PBN to avoid fault conditions and failures. (shrink)

Dans cet article, j’essaie de montrer la pertinence de la Phénoménologie de la perception pour répondre aux défis de la philosophie dans un monde à la fois déchirée et globalisateur. Si on laisse de côté la dimension théorétique du monde, nous recupérons le fond obscure de l’existence, fond de tous les espaces. Il s’agirait d’un espace primigène dans lequel on trouve le lien affectif propre de l’expérience des enfants et des primitives. Mais le vécu de ces espaces implique une perte (...) du espace de jeu qui fait possible le monde comme ouverture et intersubjectivité. La réponse de Merleau-Ponty devant le psychologisme suppose un tournant envers la philosophie traditionnelle parce qu´il réussit à garder près de sa conscience les consciences «autres» du schizophrène ou de l’enfant.

Resumen: Esta investigación busca dar cuenta de los espacios que habitan los personajes del cuento Alegres, libres y ruidosas de Pedro Juan Gutiérrez. Mediante los detalles que nos entrega el narrador, revisaremos los “operadores tonales”, estableciendo los enunciados descriptivos y los detalles inherentes a ellos, en cuanto a la composición de los personajes, así como el tipo de espacio en que se realizan, construyendo una identidad transgresora bajo la perspectiva de la poética de lo soez. En este (...) sentido, los personajes serán “máquinas deseantes” que irrumpen en la realidad con un flujo sistemático de líquidos descompuestos que arrastran residuos políticos, éticos y estéticos presentes en la Cuba contemporánea. Así, podríamos hablar de un sexo eminentemente político que no se presenta denotativamente en el cuento sino en las metáforas construidas por aquellos operadores que fijan el “tono” del relato. Por último, postulamos que los detalles funcionan como “pistas” de una historia secreta que funciona bajo la historia visible que se narra en el cuento.: This research seeks to explain the spaces inhabited by characters from the story Alegres, libres y ruidosas by Pedro Juan Gutiérrez. Thoughout the details provided by the narrator, we will review “tone operators”, determining their descriptive and inherent statements, concerning characters, the space in which they are realized by building a transgressor identity under the view poetics of the vulgar. In this sense, the characters are "desiring machines" that burst into reality with a systematic flow of decomposed liquids that drag political, ethical and aesthetic residues present in contemporary Cuba. Thus, we could speak of an eminently political sex that does not occur denotatively in the story but in the metaphors constructed by those operators who fix the "tone" of the story. Finally, we postulate that the details function as "clues" of a secret story that works under the visible story told in the tale. (shrink)

Understanding how people behave when facing hazardous situations, how intrinsic and extrinsic factors influence the risk taking (RT) decision making process and to what extent it is possible to modify their reactions externally, are questions that have long interested academics and society in general. In the spheres of Occupational Safety and Health (OSH), the military, finance and sociology, this topic has multidisciplinary implications because we all constantly face risk taking situations. Researchers have hitherto assessed risk taking profiles by conducting questionnaires (...) prior to and after the presentation of stimuli; however, this can lead to the production of biased, non-realistic, risk taking profiles. This is due to the reflexive nature of choosing an answer in a questionnaire, which is remote from the reactive, emotional and impulsive decision making processes inherent to real, risky situations. One way to address this question is to exploit VR capabilities to generate immersive environments that recreate realistic seeming but simulated hazardous situations. We propose VR as the next-generation tool to study risk taking processes, taking advantage of the big four families of metrics which can provide objective assessment methods with high ecological validity: the real-world risks approach (high presence VR environments triggering real-world reactions), embodied interactions (more natural interactions eliciting natural behaviours), stealth assessment (unnoticed real-time assessments offering efficient behavioural metrics) and physiological real-time measurement (physiological signals avoiding subjective bias). Additionally, VR can provide an invaluable tool, after the assessment phase, to train in skills related to risk taking due to its transferability to real-world situations. (shrink)

The concept of well-being of rural families is part of a theory under construction in which new theoretical elements are constantly being incorporated. This research aims to determine the influence of farmers’ knowledge on the well‑being of cocoa growing families in the departments of Santander, Huila, Meta and Caquetá, Colombia. Four categories of farmers were identified with different levels of knowledge in the management of cocoa cultivation obtained through a cluster analysis. The well-being of cocoa farmers, understood as the balance (...) in the capital endowment of rural households, was obtained through the application of a semi-structured interview with 49 variables of human, cultural, social, political, natural, built, and financial capitals. The results show that cocoa knowledge is heterogeneous in the study area, with a slight improvement towards harvesting, post-harvest and transformation links. There is a positive relationship between cocoa knowledge and the well-being of cocoa farming families. Thus, producers with greater integral knowledge, with emphasis on post-harvest and bean transformation links, showed greater well-being. The Random Forest analysis identified that human capital (political, social, human, and cultural) made the greatest contribution to well-being. The findings show that cocoa knowledge contributes to the well-being of rural households to the extent that it favors vertical relationships (linkages with local governments) and horizontal relationships of producers (participation of association managers, sharing knowledge with friends, neighbors and partners, and cocoa training).

The focus is on the meaning of ὑπόϑεσις in Irenaeus of Lyons’ Adversus haereses. Our case is to argue that two different elements converge in ὑπόϑεσις or its translations in the Latin version of AH. The first stems from the Greek literary field, in which ὑπόϑεσις means the “subject” or “plot” of a dramatic or poetic composition. The second is related to the philosophical meaning of ὑπόϑεσις as “that which is placed under” or “foundation”. On the one hand, Irenaeus uses (...) ὑπόϑεσις theologically to express the plot of the historia salutis, so that the term can be understood as teaching or doctrine. On the other hand, this ὑπόϑεσις is at the same time a regula, the normative foundation of all the elements that take part in God’s economy of salvation. (shrink)

Ensayaremos un philosophema KφP. El camino de la experiencia estética es un camino impropio y kinestésico, lleno de potencialidades, indeterminado, con acontecimientos sucesivos y engañosos. Nietzsche se dio cuenta de ello en Sobre la música y la palabra. De una manifiesta metafísica del arte se trata de transitar, por medio de nuestra frenética inteligencia, a una experiencia estética verdadera, superando cualquier superstición que contamine de ficciones el territorio de la phantasia, porque, como decía Heródoto (1920): αὐξομένῳ γὰρ τῷ σώματι συναύξονται (...) καὶ αἱ φρένες (pues junto con el cuerpo que crece también crecerá su mente).

El presente artículo se ocupa de la comunidad melkita, en tanto que grupo que se conformó como una identidad eclesiástica surgida en el periodo islámico, en el corazón del Islam y por tanto no en Constantinopla. De ahí que insistamos en que aquellos rasgos de identidad de esta comunidad que vienen dados por la fe de la Ortodoxia bizantina, formada a partir de grupos de calcedonianos siriacos anti-monotelitas como grupo diferenciado de los jacobitas, que serán identificados posteriormente con los cristianos (...) del califato omeya que aceptaron las enseñanzas del sexto concilio ecuménico de la iglesia imperial bizantina en el año 681. En este contexto, el uso de la denominación melkita no ha de entenderse como sinónimo de «ortodoxos griegos», sino de «calcedonianos», que en el caso de los cristianos siriacos identifica a aquellos que siguieron el dogma diotelita.

In this paper I suggest that in order to avoid some of the difficulties to which the contemporary discussion on the transcendental arguments has led we must discriminate different ways of understanding the sceptic’s challenge that Kant faces in the Critique of Pure Reason. In the first part, I expound a dilemma into which the Kantian epistemology could fall if we accept the characterization of the transcendental arguments as anti-sceptic arguments. In the second part, I present three ways of understanding (...) the sceptic’s challenge and the different strategies that could be developed to answer it correctly. (shrink)

Metallothioneins (MTs) are ubiquitous proteins with the capacity to bind heavy metal ions (mainly Cd, Zn or Cu), and they have been found in animals, plants, eukaryotic and prokaryotic micro‐organisms. We have carried out a comparative analysis of ciliate MTs (Tetrahymena species) to well‐known MTs from other organisms, discussing their exclusive features, such as the presence of aromatic amino acid residues and almost exclusive cysteine clusters (CCC) present in cadmium‐binding metallothioneins (CdMTs), higher heavy metal‐MT stoichiometry values, and a strictly conserved (...) modular–submodular structure. Based on this last feature and an extensive gene duplication, we propose a possible model for the evolutionary history of T. thermophila MTs. We also suggest possible functions for these MTs from consideration of their differential gene expressions and discuss the potential use of these proteins and/or their gene promoters for designing molecular or whole‐cell biosensors for a fast detection of heavy metals in diverse polluted ecosystems.

Previous studies making use of indirect processing measures have shown that perceptual grouping can occur outside the focus of attention. However, no previous study has examined the possibility of subliminal processing of perceptual grouping. The present work steps forward in the study of perceptual organization, reporting direct evidence of subliminal processing of Gestalt patterns. In two masked priming experiments, Gestalt patterns grouped by proximity or similarity that induced either a horizontal or vertical global orientation of the stimuli were presented as (...) masked primes and followed by visible targets that could be congruent or incongruent with the orientation of the primes. The results showed a reliable priming effect in the complete absence of prime awareness for both proximity and similarity grouping principles. These findings suggest that a phenomenal report of the Gestalt pattern is not mandatory to observe an effect on the response based on the global properties of Gestalt stimuli. (shrink)

Ethical banking, microfinance institutions or certain credit cooperatives, among others, grant socially responsible loans. This paper presents a credit score system for them. The model evaluates social and financial aspects of the borrower. The financial aspects are evaluated under the conventional banking framework, by analysing accounting statements and financial projections. The social aspects try to quantify the loan impact on the achievement of Millennium Development Goals such as employment, education, environment, health or community impact. The social credit score model should (...) incorporate the lender’s know-how and should also be coherent with its mission. This is done using Multi-Criteria Decision Making. The paper illustrates a real case: a loan application by a social entrepreneur presented to a socially responsible lender. The decision support system not only produces a score, but also reveals strengths and weaknesses of the application. (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.

Knowledge of diverse sexual motivations can have profound implications for our comprehension of the causes, correlations, and consequences of sexual behavior. This study had two objectives: on the one hand, to determine the different motives why young Spanish university students have sex and their relationship with different sociodemographic and psychosexual variables and sexual behavior; on the other hand, to review and improve the psychometric properties of the Sexual Motivations Scale and validate it in Spanish. Participants were 805 university students of (...) both sexes, aged between 18 and 26 years, who completed a battery of online questionnaires. Significant associations were found between young people's sexual motives, especially the motives of coping, peer pressure, and enhancement, the sociodemographic variables, sexual behavior, and psychosexual variables. Also, a new structure of the Sexual Motivations Scale was proposed, with the elimination of the factor of Self-Affirmation. The discussion highlights the relevance of the results obtained due to their implications in the promotion of sexual health, in addition to achieving the first instrument validated in Spanish for the evaluation of sexual motivations.

El texto que Massignon creyera ser la muestra del más antiguo "Padre nuestro" en árabe, tal como se nos ha conservado no es sino una adaptación musulmana que queda lejos de poder representar una versión directa de la Oratio Dominica, lo cual obliga a rastrear las antiguas versiones árabes del "Padre nuestro" entre la producción literaria cristiana. En ésta, tanto las versiones orientales como las occidentales ofrecen lecturas distintas en función de su procedencia doctrinal: las orientales atienden, a grandes rasgos, (...) a una doble clasificación, muestras ortodoxas y monofisitas, en tanto que las occidentales, además de evidencias una compleja tradición textual de los textos bíblicos neotestamentarios, parecen reflejar, cuando menos y a simple vista, interferencias orientales de procedencia monofisita, que llevan a reconsiderar la naturaleza, las fuentes y las familias textuales de las traducciones que circularon por al-Andalus .
