O artigo analisa a questão da crescente precariedade no mundo do trabalho à luz das teses do brasileiro Ruy Mauro Marini e do conceito de superexploração do trabalho, formulado por esse autor no âmbito de uma teoria marxista da dependência, a princípio, para designar regime específico das formações sociais latino-americanas. Nesse sentido, em um primeiro momento, analisamos algumas tendências mundiais em curso no mundo do trabalho e, em seguida, os processos de transformação nos regimes de superexploração do trabalho nos países (...) dependentes e sua atual apresentação fenomênica nos países capitalistas centrais. Ao fim, analisamos a vigência e a centralidade dessa categoria, assim como suas implicações para o devido entendimento da política e das novas morfologias da classe trabalhadora na América Latina e no mundo.

Lo que se introduce como metafísica de la luz adherida a una connotación religiosa, resulta ser uno de los temas más dominantes y discutidos durante el período medieval, aunque más exhaustivamente abordado durante el período escolástico, es decir, desde finales del siglo IX hasta mediados del siglo XIV. Sin embargo, las reflexiones sobre la idea de "lux" se iniciaron con el neoplatonismo, más precisamente con el egipcio Plotino, quien abanderó la idea de revitalizar la doctrina de la Academia, que fue (...) fundada por Platón. De hecho, la consideración de la luz se destaca como uno de los elementos que repercutió en la filosofía patrística medieval, estableciendo una base sólida para las formulaciones del dogma cristiano. Teniendo esto en cuenta, el propósito del artículo es introducir algunos significados del concepto de lux, tal como lo desarrolló Plotino. (shrink)

La búsqueda de lo divino, que aparece en el cristianismo como un asunto espiritual, perfila ser tema de importancia para una mística agustiniana que tiene referencias a la figura de Dios, esto es, expresiones que intentan describir la naturaleza divina. Así pues, el santo de Hipona, a través de términos como luz y verdad, presenta los rasgos de un Dios que parece mostrarse tal como es, pero para alcanzar una visión tan inefable, es necesario el deseo de esta; una búsqueda (...) de Dios que, traducida en amor, es un proceso de ascenso a la verdad de lo divino permeado por ese intenso deseo de ello. De manera que un deseo de Dios posiblemente connota una erótica entendida como amor vehemente; el cual, para interés del presente artículo, puede resignificar la noción común de erótica y de sexualidad inherentes al carácter relacional del ser humano, a veces visto con sospecha.

ResumoNo início do século xviii, Isaac Newton publicou seu principal trabalho sobre óptica, o Opticks. Impregnado por uma perspectiva indutiva, o livro logo se tornou a principal referência para os estudos sobre a luz e as cores, sendo amplamente popularizado pelos seguidores de Newton. Neste artigo, analisamos como dois importantes livros contribuíram para essa popularização e também qual era a imagem de ciência que tencionavam propagar, o Élements de la philosophie de Newton de Voltaire e o Newtonianismo per le dame (...) de Algarotti. Será possível perceber que ambos os autores distorceram o conteúdo do livro de Newton, no intuito de propagar uma imagem idealizada das ideias newtonianas e da própria filosofia natural.In the beginning of 18th century, Newton published his main work about light and colors, the Opticks. Impregnated by an inductive perspective, the book became the major reference for the studies about light and colors, being widely popularized by Newton's followers. In this article, we analyze how two important works contributed to this process of popularization and also what image of science they intended to propagate: Voltaire's Elements of Newton's philosophie and Algarotti's Sir Isaac Newton's philosophy explain'd for the use of the ladies. We will be notice that both authors distorted the content of the Opticks, in order to propagate an idealized image of Newtonian ideas and natural philosophy itself. (shrink)

La metafísica dinamicista que despunta en la segunda mitad del siglo XIII, reivindicando el estatuto intencional o real disminuido de la esencia como tal a la luz de la novedosa lógica modal, abre la senda al indeterminismo, con la sintaxis de mundos alternos suspendida en la radical contingencia de la creación. El ensayo plantea un diálogo de esa metafísica, en clave de ontología cuántica, con la moderna mecánica de estados posibles que continuará con la revisión del principio de identitas indiscernibilium (...) sobre el carácter simétrico o antisimétrico de la función de onda.

Despite the abundant production of catecismos in 16th century Spain, few of them were addressed directly to the new converted population, and fewer still were translated into or written in Arabic. Given the dimension of the Morisco question within Catholicism at the time, this scarcity is striking. Archbishop of Valencia and attending member of the Council of Trent, Martín Pérez de Ayala, commissioned one of these rare texts, the Doctrina Christiana en Lengua Arauiga y Castellana, written in Valencian (...) Arabic. The text encloses a brief catechism containing mainly prayers but also a set of instructions about both Arabic phonetics and doctrinal matters. The present article intends to study the language ideology present in the translation of Christian doctrine into Arabic. In order to do so, it asks questions such as whether the emphasis on spoken Arabic is a conscious distance from a Koranic Arabic language, and how religious space is shaped through language.

Este artículo propone una revisión crítica sobre los alcances del transhumanismo en la esfera de la Psicología. Para ello, se expondrán antecedentes y se definirá lo que se entiende por transhumanismo y el resultado de éste, denominado poshumanismo. A través de características humanas tan básicas y diversas como la cognición, el sufrimiento y la identidad, se discute sobre los inéditos cambios que la ejecución y logro de las propuestas transhumanistas significarían para la sociedad, el cómo la psicología podría prever y (...) anticipar un escenario así de radical, y la necesidad y urgencia de nuevas teorías éticas que ayuden a comprender los fenómenos en cuestión.

El presente texto quiere contribuir al debate propuesto por Nómade desde una lectura crítica de la Universidad en la América Latina. Esta lectura recupera dos cuestiones que se comprenden como estructurales y estructurantes en el proceso de producción de conocimiento: la cuestión epistémica y la de la formación de sujetos. Estas reflexiones se abordan desde tres aspectos que se proponen como análisis del presente: a) la perdida de sentido en la relación sujeto / sujeto en los procesos de formación; b) (...) la ruptura del lazo social desde las políticas en educación superior; y c) la pérdida de relevancia social del mundo universitario. En este marco se delinean aspectos centrales de una propuesta epistémica –epistemología de la conciencia histórica– y su traducción tanto en lo metodológico como en lo didáctico. (shrink)

The comparative study of synchronic occurrences of a particular construction in interactional corpora from different languages can provide a complete understanding of the development of the construction as a response to some basic intimately associated set of interactional moves and cognitive demands. A comparative formal analysis of lists in Spanish and English conversations shows that in both languages the construction has developed a stylized intonation pattern based on the holding of tones by means of lengthening of nuclear syllables, a durable (...) syntactic organization based on parataxis and an almost identical inventory of lexicalized expressions to index the end of the list. A parallel analysis of lists in their interactional contexts shows that in both English and Spanish conversation the formal properties of lists emerge as adaptations to a recurrent set of communicative tasks. The first type of `framing' lists is used for its incremental structure in the negotiation of common background between interlocutors, whereas the second type of `demonstrative' lists is used for its rhetorical structure to provide evidence for a claim and is directed to obtaining agreement.

Magnífico libro ha tenido a bien reeditar la editorial madrileña Encuentro, situándolo como el primer volumen de la colección Mínima Política. En él, además de realizar algunas correcciones y estructurar la obra de forma más manejable para el lector, se ha encargado del estudio preliminar el profesor Jerónimo Molina, como ya hiciera con otras obras del mismo autor, Teoría y sistema de las formas políticas e Introducción al Derecho político actual, hace unos pocos años. En esta introducción, se nos ofrece (...) un recorrido biográfico, intelectual y político por Francisco Javier Conde, sencillo, directo y profundo. Propio de quien tiene un riguroso conocimiento del autor y de su obra. Con su lectura conseguiremos enmarcar correctamente este libro en la trayectoria vital e intelectual de Conde, entre la actitud intelectual del realismo político, el fracaso en la vida de actividad política y el olvido arrastrado hasta casi nuestros días. Y digo casi, porque, según lo que hemos dicho, no son pocos los que honran a Conde y su trabajo intelectual, de gran mérito. No en vano señala el profesor Molina que este libro es un pequeño clásico contemporáneo. (shrink)

The traditional teaching style in which the teacher is in control and there is a submissive attitude in students is predominant in Mexico. The development of identity in preadolescence is subjected to social groups, which could develop interpersonal difficulties through the controlling teaching style. Although the fear of negative evaluation in students and competitive sport has been studied in education, relatively little research has been done in the area of physical education in relation to the controlling style. The purpose of (...) this study was to investigate the correlation and predictive relationship between controlling teaching and the fear of negative evaluation mediated by the frustration of the basic psychological needs, controlled motivation, and individualism/competitiveness through the theoretical framework of self-determination theory. Participants were 1132 students in the fifth and sixth grades in public elementary schools in the state of Chihuahua, Mexico, with ages between 10 and 13. Results indicate the perceived controlling teaching style positively predicted the fear of negative evaluation in students of this study through BPN frustration, that is positively related to low-quality motivation, which is related to a higher level of individualism/competitiveness. This, in turn, is proven to be a predictor of the fear of negative evaluation. The results also discuss the promotion of the autonomy support style, avoiding the controlling teaching style, for the minimization of negative results related to the perception of fear and the development of student well-being both within and beyond the school context.

In this article, I argue that the main contribution of Hegel's philosophy of right to the contemporary political debate is that it opens a window on the idea that liberalism and individual freedom are incompatible. My main thesis is that the liberal conception of the State and law, structured from a nonrelational account of singularity, ends up denying the individual freedom that it claims to defend. I begin by reconstructing the Hegelian concept of freedom from its most general lines, showing (...) that being free consists in wanting to become someone and not so much in wanting to do something. After showing that the purpose of becoming someone can only be fulfilled in a social medium, I focus on Hegel's critique of the liberal state (as expounded in the section on “civil society”). I argue that civil society structurally impedes individuals from realizing their purpose of becoming someone: the economical interactions of civil society give rise to impersonal and inscrutable mechanisms, which take the social conditions of people's individuation beyond their control. Finally, I claim that (rational) individual freedom consists in being able to thematize and democratically control the very social conditions of individuation through the State and law. (shrink)

The aim of this study was to analyze the explanatory level of the variables advertising influence, verbal messages, social models and social situations as regards body dissatisfaction, weight worry, and bodily discomfort. The study was conducted in a convenience sample of 206 Mexican women with an average age of 22.12 years. Structural equation modeling was used to analyze the direct and indirect effects of the independent variables on the dependent ones in three hypothetical models proposed. In the case of the (...) model proposed for body dissatisfaction, it was found that the set of variables had 79% of variance explained and showed adequate goodness-of-fit indices. The model for weight worry had 62% of variance explained and an acceptable goodness of fit. Finally, the model for bodily discomfort had 72% of variance explained and showed adequate goodness of fit. It is concluded that social influences have a significant impact on body image. Verbal messages had the strongest impact on the variables studied. (shrink)

Within this essay, I seek to understand how the patriarchy impacts the concept of body memory and creates gendered bodily behaviors. I first explain and define the relationship between one’s incorporative memory and affective framing. Given this relationship, I explore what male validation is and how it becomes embodied. I argue that the formation of the incorporative memory and affective framing under the patriarchy creates an embodied experience of male validation. As women begin to understand gender roles, they shift how (...) they move their bodies, and continue to display this gendered movement because men validate it. (shrink)

Tras la lectura de esta obra, reconocemos que su autora, Stephanie Graf, mantiene una signatura o estilo constante en cada parte, capítulo y subtítulo, pues le interesa plantear una trama, un tablero para dialogar con el trabajo de Walter Benjamin y de Theodor W.

Metabolomics, including lipidomics, is emerging as a quantitative biology approach for the assessment of energy flow through metabolism and information flow through metabolic signaling; thus, providing novel insights into metabolism and its regulation, in health, healthy ageing and disease. In this forward‐looking review we provide an overview on the origins of metabolomics, on its role in this postgenomic era of biochemistry and its application to investigate metabolite role and (bio)activity, from model systems to human population studies. We present the challenges (...) inherent to this analytical science, and approaches and modes of analysis that are used to resolve, characterize and measure the infinite chemical diversity contained in the metabolome (including lipidome) of complex biological matrices. In the current outbreak of metabolic diseases such as cardiometabolic disorders, cancer and neurodegenerative diseases, metabolomics appears to be ideally situated for the investigation of disease pathophysiology from a metabolite perspective.

También sus matices teológicos propios han sido resaltados, así como sus fuentes.

The article discusses the problems of philosophical geography, philosophical multipolarity, georationality. The debates on these issues are becoming interdisciplinary. Specialists in Eastern philosophies and cross-cultural communications as well as epistemologists, scientific methodologists, cognitive scholars, synergists became participants of the discussion held at the Institute of Philosophy of the Russian Academy of Sciences. The problem of Eurocentrism in academic philosophy has become the main topic of discussion. The opponents of the “regional” multipolarity argued that the Western European tradition of rationality was (...) an example of the rationality per se. The proponents, who relied heavily on the ad professionem arguments, advocated multipolarity and demonstrated the irreducibility of the world-pictures, languages and ontologies of philosophical systems. A point of view was expressed that Eurocentrism had an ideological background. The disputants noted that there was need to redefine or clarify such fundamental concepts as logic, rationality, scientific rationality, universalism, processuality. The redefinition of the concept of rationality is for the studies of various types of rationality outside European cultures. Methodologists of science drew attention that the cognitive problems of intercultural communications turned out to be similar to the problems faced by theory of complexity. The analysis of philosophical, logical and other cases in various “zones of exchange” reveals a plurality of directions in the global and local socio-cultural spaces. The panelists raised the question of the role of philosophy in the global world and its responsibility in uniting nations. The authors of the article draw attention to many functions that the Western European conceptual system performs in the formation of philosophical language, mentality and communication. The dynamics of philosophical discussions, the dialogue of the West and the East lead to the clarification of philosophical positions, the emergence of new concepts and meanings as well as the formation of discourses of the future.

The article examines the conquest of the New World in the focus of interaction of different types of thinking in the clash and conflict of two civilizations, which develop in different ways and which are at different levels of social and economic development. The result of this clash was the destruction of the material, spiritual and intellectual traditions of indigenous cultures that existed on the American continent. The conquest of America is one of the most revealing examples of the clash (...) of civilizations, analyzing which, with particular clarity, one can observe contradictions between different types of world perception. The answer to questions about what kind of knowledge Nahua-speaking people possessed, what role knowledge played in their society, who was the creator, carrier and translator of knowledge about the world, reveals one of the main reasons that led to a rapid and irretrievable destruction of culture of “metaphors and numbers.” The author reveals the role of Catholic monks in preserving the spiritual, scientific and philosophical heritage of the Mexican culture, thanks to which we have the opportunity to touch the thought of the Nahua people, existing not in the form of traditional texts but in the form of an oral tradition, which accompanied visual images of graphic semantic writing. It shows how important the system of education and upbringing in the society of pre-Columbian Mexico was, how it solved the tasks of preparing young people for the performance of social functions. The destruction, as a result of the con- quest, of the system that regulated the daily life of each person and determined the ultimate destiny of the people in the shortest possible time led to the death of the entire civilization.

RESUMEN Se aborda el pensamiento de E.M. Cioran desde la perspectiva de un sinsabor vital denominado sentimiento de muerte. El término, aunque aparece solo en su primer escrito, es transversal a toda su obra, puesto que para el autor los seres humanos nos intuimos como posesos de la muerte en cada momento de nuestra existencia. Esto cambia el tono normal de la vida, al poner frente a la persona una realidad carente de sentido y dominada por circunstancias radicales y limitantes (...) como el dolor y la agonía, que culmina en una atmósfera gobernada por la intuición trágica de la vida. ABSTRACT The article addresses the thought of E.M. Cioran from the perspective of that vital uneasiness known as the sentiment of death. Although the term appears only in his first book, the idea cuts across his entire work given that, for Cioran, human beings intuit themselves as possessed by death at every moment of their lives. When persons are faced with a meaningless reality, dominated by radical and limiting circumstances such as pain and agony, the whole tenor of life changes until it becomes a tragic intuition of life.
