The theory of chemical symbiosis suggests that biological systems started with the collaboration of two polymeric molecules existing in early Earth: nucleic acids and peptides. Chemical symbiosis emerged when RNA-like nucleic acid polymers happened to fold into 3D structures capable to bind amino acids together, forming a proto peptidyl-transferase center. This folding catalyzed the formation of quasi-random small peptides, some of them capable to bind this ribozyme structure back and starting to form an initial layer that would produce the larger (...) subunit of the ribosome by accretion. TCS suggests that there is no chicken-and-egg problem into the emergence of biological systems as RNAs and peptides were of equal importance to the origin of life. Life has initially emerged when these two macromolecules started to interact in molecular symbiosis. Further, we suggest that life evolved into progenotes and cells due to the emergence of new layers of symbiosis. Mutualism is the strongest force in biology, capable to create novelties by emergent principles; on which the whole is bigger than the sum of the parts. TCS aims to apply the Margulian view of biology into the origins of life field. (shrink)

Proponemos una revisión crítica a una corriente interpretativa de base lingüística de las religiones prerromanas del área indo-europea de la Península Ibérica que se ha venido desarrollando durante los últimos quince años; para ello tomamos como referencia un reciente trabajo de B.M. Prósper (Lenguas y religiones del occidente de la Península Ibérica, Salamanca, 2002) en el que se exponen los puntos de vista de dicha hipótesis interpretativa. Nuestro trabajo revisa sus tres planteamientos metodológicos básicos: su consideración de dichas religiones como (...) cultos idolátricos, su base evolucionista decimonónica y su manifiesto anti-dumezilianismo. Nuestra propuesta consiste en integrar el aporte de la lingüística dentro del ámbito de la Historia de las Religiones como un tipo de análisis que contribuya, con otros, a la construcción de hipótesis explicativas del fenómeno religioso de dichas sociedades.

Renal replacement therapy is the indicated treatment for individuals with chronic kidney disease (CKD) to survive. However, not all sick people have access to the same treatment. This study compares renal care in two developing countries with different health systems. Specifically, it explores hemodialysis treatment from the perspective of low‐income individuals. A qualitative, comparative study was performed in Brazil and Mexico. Using purposive sampling, the research was based on open‐ended interviews with nineteen participants with kidney failure undergoing hemodialysis treatment in (...) public hospitals and ten relatives. According to our results, Brazilian participants perceived hemodialysis care as satisfactory because of health personnel courtesy as well as free access to dialysis treatment, prescription drugs, hospitalization and transportation. However, they reported deficiencies in the care they were receiving due to shortages of specialists, prescription drugs, laboratory tests and transportation. Mexican participants, in contrast, highlighted the catastrophic costs of medical care because they had no free access to renal therapy, nor adequate financial resources. Our findings suggest that low‐income Brazilian CKD sufferers experience renal care differently, as they are more satisfied and face less obstacles with hemodialysis compared with those of Mexico. More studies on the topic are needed. (shrink)

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)

Alberto Magno foi o primeiro grande comentador de Aristóteles entre os cristãos. Em seu Prólogo à Ética a Nicômaco, defronta-se ele com a divisão da philosophia moralis em individual, econômica e política. Seus antecessores, porém, não faziam união entre os três ramos, enquanto Alberto, usando praticamente os mesmos argumentos e reinterpretando-os a seu modo, consegue recuperar a unidade da ética.

En este trabajo me propongo comparar el patrón argumentativo de los sofistas del siglo V a. C. tal como son retratados en la obra de Platón con el de los erísticos del _Eutidemo_. Defenderé que ninguno de estos sofistas es presentado por Platón como experto en dialéctica refutativa, actividad discursiva que caracteriza a la erística. Por el contrario, el retrato platónico de Pródico, Hipias, Gorgias y Protágoras los muestra como incapaces, desinteresados u hostiles a la argumentación de tipo dialéctica.

Analizo en este trabajo el alcance real de la idea de "espíritu del pueblo" en el pensamiento jurídico de F. C. v. Savigny. Sugiero la posibilidad de que las apelaciones al espíritu del pueblo no sean más que una pantalla retórica que encubre una opción de fondo por una visión lógico-sistemática (y ahistórica) del Derecho, en la que jugaría un papel importante la idealización del Derecho romano en cuanto ratio scripta.

In 2000, the world of anthropology was rocked by a high-profile debate over the fieldwork performed by two prominent anthropologists, Napoleon Chagnon and James V. Neel, among the Yanamamo tribe of South America. The controversy was fueled by the publication of Patrick Tierney's incendiary Darkness in El Dorado which accused Chagnon of not only misinterpreting but actually inciting some of the violence he perceived among these "fierce people". Tierney also pointed the finger at Neel as the unwitting agent of a (...) deadly measles outbreak. Attracting a firestorm of attention, Tierney's book went straight to the heart of anthropology's most pressing questions: What are the right ways to study a tribal people? How can scientists avoid unduly influencing those among whom they live? What guidelines should govern the interactions - economic, social, medical, and sexual - between a scientist in the field and the people being studied? This volume represents anthropology's thoughtful, measured reply to the issues raised by this heated controversy. Placing the dispute within the context of ongoing debates over the ethics of biomedical research among human populations, the contributors to this volume discuss how the interaction between investigators and their subjects can most sensibly be governed. They consider the responsibility of the media in disseminating anti-scientific and pseudo-scientific views, and how scientists might best educate journalists to enable them to effectively educate others. In the wake of what was widely construed as a major scientific scandal, this landmark volume lays out in detail the principles and ground rules of anthropological and scientific fieldwork. (shrink)

Durante el siglo IV a. C. los intelectuales griegos discutieron sobre los alcances y características de la labor filosófica, en un intento por delimitar esta práctica distinguiéndola de otras. En este artículo me centraré en el retrato del sofista como contracara del filósofo. Analizaré específicamente la respuesta platónica al ataque que Isócrates dirige contra todos los discípulos de Sócrates en Contra los sofistas y Encomio de Helena. Defenderé que la estrategia de Platón para eludir dicha crítica consistió en construir en (...) el Eutidemo y la quinta definición del Sofista un personaje que reúne los rasgos más censurados por Isócrates: el sofista erístico. Argumentaré que esta figura no remite a los sofistas del siglo V a. C., sino que tras ella se encuentran ocultos los representantes del grupo megárico, a quienes Platón habría colocado como los principales merecedores de la embestida isocrática. During the fourth century BC, Greek thinkers discussed about the limits and characteristics of philosophy in order to distinguish it from other practices. In this paper, I will focus on the portrait of sophists as diametrically opposed to philosophers. Specifically, I will discuss the platonic answer to the charge that Isocrates directed against all Socrates’ disciples in the treatises Against the Sophists and Encomium of Helen. I will defend that Plato’s strategy to avoid his critics was to develop, in the Euthydemus and the fifth definition of the Sophist, a character that combines the most significant attributes censured by Isocrates: the eristic sophist. I will argue that this figure does not refer to the Sophists of the fifth century BC., but to the Megaric group. They would have been those who, according to Plato, really deserved the Isocratic attack. (shrink)

O tema da predestinação dos homens, uns, para a salvação eterna, outros, para a condenação, constitui, aparentemente, apenas uma questão teológica. Examinando com maior profundidade dois casos em que este tema foi causa de polêmicas, dentro do mundo cristão, percebesse que, por trás das questões dogmáticas, havia um conteúdo político não manifesto que poderia abalar a ordem vigente.

It is an intimate experience for us to think, to understand and to perceive things as being identical to themselves, and to suppose, consequently, that things are truly “what” they are. Something is always conceived as itself. The given is given full of itself in all its modifications. For instance, I can think or perceive partially some lips, I can see them almost in their whole or in some of their aspects, or just see them disappear. But it does not (...) seem to be possible to think or to perceive a given as almost itself, as an aspect or as part of itself. It is the aim of this work to study the assumptions and conditions for the original position of sameness in experience, just as it occurs in the synthesis of the datum singular and distinct. The polarization of single tone (einstimmig) intentional rays in an αvτó already contains the aporiae peculiar to the experience of the identical, whose revelation shall lead us, on the one hand, to one of the nuclei of the analysis of passive synthesis, and, on the other hand, to point up how critical revision of the numerical or extensional model of self-identity is for the unity of meaning. Then, it will be a question of pointing out the reasons why in a phenomenology of identity, the renunciation of the phenomenological legitimacy of the αvτó as a guarantee for the different positions of identity must be observed.

45~ JOURNAL OF THE HISTORY OF PHILOSOPHY 34:3 JULY 1996 text" , and an element of "oralism" remains in all of Plato's written works. Nonetheless, Robb's "speculations" on the Platonic dialogues are certainly worth reading. Robb is quite aware that his book stirs up controversial issues, and some of these are briefly stated and discussed in his concluding chapter, "Homer, the Alphabet, and the Progress of Greek Literacy and Paideia." And yet in the very notions of "literacy" and "progress," some (...) weaknesses in Robb's work can be found. For example, as W. V. Harris observed in his Ancient Literacy , 3ft., there is no single definition of literacy or orality, and although Robb cites Harris's book , he takes no special account of it in attempting to define or characterize what he means by "orality" and "literacy." And in his zeal to provide a survey of the influence of alphabetic literacy on Plato, Robb perhaps oversimplifies the tension that existed between the spoken and written work in the ancient world. Much of Greek "literature" remains the product of literate, slave- owning, and well-educated authors, written for their peers. Robb suggests as much in his discussion of mousild and sunousia , and one might desire a "sociology" of ancient Athens, for example, in which economic status and.. (shrink)

Poco se ha escrito sobre uno de los intentos más radicales de fundamentación del conservadurismo; como son las obras de Hans Freyer, Arnold Gehlen y Helmut Schelsky (principales representantes de la Escuela de Leipzig). Este artículo sistematiza la tentativa de la Escuela de Leipzig de justificar epistemológicamente el conservadurismo como régimen socio-político. Caracterizaremos el concepto de conservadurismo en la Escuela de Leipzig (I), se expondrá su fundamentación epistemológica en Freyer (II), su continuación en Gehlen (III) y su variante en Schelsky (...)

The purpose of the paper is to establish the different aspects that the Neoplatonic philosopher states in relation with the kalokagathós on three diverse levels: the aesthetic perception, the intuition of beautiful activities and the contemplation of the Beautiful that it is displayed to the Good/One. It is commented also the differences with Plato (...) and some distinctions with the interpretations in regard to the Beautiful that have been outlined by some contemporary scholars and writings.

La obra más popular de Francisco Sánchez, Quod nihil scitur (1581), transmite un pensamiento completamente escéptico. No obstante, otros escritos como Carmen de Corneta anni MDLXXVII (1578), nos ofrecen diversas ideas de cómo consideraba Sánchez que era posible el conocimiento científico como, por ejemplo, su pensamiento sobre las relaciones causales entre objetos naturales.
