China: lo que se puede y no se puede contar de la historia del PCCh

Por • 21 feb, 2018 • Category: Opinion

En medio de una campaña multifacética para mantener la ortodoxia ideológica, la administración del Presidente Xi Jinping ha reforzado los esfuerzos para preservar el monopolio del PCCh sobre la historia, revitalizando una campaña contra el “nihilismo histórico”, o los desafíos a la versión de la historia en la que descansa en parte la legitimidad del Partido. La actual campaña ha sido impulsada por la creencia de que la ambiguedad en este frente ayudó aprovocar el colapso de la Unión Soviética.



From Kantian-Reinen Vernunft to the Real Dark Energy Density of the Cosmos via the Measure Concentration of Convex Geometry in Quasi Banach Spacetime

Por • 15 feb, 2018 • Category: Opinion

The paper argues strongly in favour of the opinion that Kantian pure reason could be implemented via pure mathematics to reveal a true deep aspect of the fundamental monads of the real physics of the cosmos. Thus using a remarkable pure mathematical-geometrical result stating that under certain conditions a manifold will have 96 percent of its volume concentrated near to its surface, we conclude that the 96 percent dark energy causing the edge of our universe to expand is a direct consequence of this pure geometrical result. From this viewpoint we could generalize our finding to mean that scientific philosophy is not only an important ingredient of human cultural existence but a real immensely important tool in analyzing the reality of the cosmos at the quantum level as well as its large scale structure.



Four Physics Puzzles Viewed Ontologically: Duality, Collapse, Probability and Nonlocality

Por • 9 feb, 2018 • Category: Opinion

Wave-particle duality, wave function collapse, objective probability and nonlocality constitute four prominent puzzles in modern physics. Although these four topics may appear unrelated, a closer examination reveals that they do share some common assumptions at the foundational level that have characterized physics for the last 100 years. Progress can be made on these four topics only if we understand and possibly revise some long-held assumptions. This essay examines physics from the ontological perspective.



Nancy, Badiou y Lacan: la composición compleja del concepto

Por • 5 feb, 2018 • Category: Opinion

En este artículo presentaremos primero dos discusiones muy puntuales que confrontan a Badiou con Nancy y Lacan en torno al vacío y al infinito. Mostraremos después cómo pensamos que se articula el concepto, tanto en filosofía como en psicoanálisis, a la luz de dichas complejidades y de las imbricadas relaciones entre los diversos dispositivos de pensamiento que ellas implican.



El xiísmo: ¿un “pensamiento” prematuro?

Por • 28 ene, 2018 • Category: Opinion

Xi es un nacionalista, un comunista patriótico si me apuran, que debe hacer lo imposible por evitar el fracaso en el momento más crucial de la historia contemporánea china, cuando más cerca parece estar el gigante asiático de alcanzar el objetivo de cumplir la modernización ansiada desde finales del siglo XIX poniendo fin a dos siglos de decadencia. Los dirigentes chinos piensan mucho en clave histórica y cultural. De ahí que se extremen las cautelas y se cierre filas para evitar riesgos que puedan hacer derrapar el proceso. Todo vale para ello, incluso lo que pudiera parecer un pensamiento prematuro.



Relational Characterisations of Paths

Por • 22 ene, 2018 • Category: Opinion

Binary relations are one of the standard ways to encode, characterise and reason about graphs. Relation algebras provide equational axioms for a large fragment of the calculus of binary relations. Although relations are standard tools in many areas of mathematics and computing, researchers usually fall back to point-wise reasoning when it comes to arguments about paths in a graph. We present a purely algebraic way to specify different kinds of paths in relation algebras. We study the relationship between paths with a designated root vertex and paths without such a vertex. Since we stay in first-order logic this development helps with mechanising proofs. To demonstrate the applicability of the algebraic framework we verify the correctness of three basic graph algorithms. All results of this paper are formally verified using Isabelle/HOL.



On Rules

This paper contains a brief overview of the area of admissible rules with an emphasis on results about intermediate and modal propositional logics. No proofs are given but many references to the literature are provided.



Veinte tesis sobre el significado histórico social y la naturaleza de la Revolución rusa de 1917 y de la URSS

Por • 4 ene, 2018 • Category: Opinion

la contraposición entre la experiencia histórica revolucionaria soviética y el proyecto emancipador del proletariado en Marx y Engels, expresó la ausencia de una teoría crítica –por parte de los dirigentes revolucionarios– del desarrollo capitalista. Teoría crítica, que debió mostrar, esencialmente, el grado real de desarrollo de las fuerzas productivas al interior de las relaciones sociales de la producción capitalista. Y, a partir de ahí, evaluar y medir la temporalidad del capitalismo; es decir, qué tanto había cumplido su misión histórica, y ergo, qué tanto se acercaba a su necesario, posible y deseado fin. Y, por lo tanto, qué tan lejos o cerca se encontraba la actualidad de la revolución socialista mundial.



An Analysis of the relationship between WTI term structure and oil market fundamentals in 2002-2009

Por • 28 dic, 2017 • Category: Opinion

The main objective of this paper is to analyze the behavior of the term structure of the WTI futures market between 2002 and 2009, period known by a sustained price rise followed by a price slump and again by a new price rise. To achieve this goal, we use Principal Component Analysis (PCA) to decompose WTI futures price series into components which are used to explain series variability (e.g. changes in its term structure). After it, we try to identify how changes in oil markets fundamentals (physical and financial) may have contributed to oil futures term structure variability. The impact of these variables on WTI term structure is assessed using impulse-response functions and variance decomposition analysis. This work is of interest to market analysts, hedgers, and traders, among others, because it helps to clarify how changes in oil markets may affect their strategies in these markets.



Assessment Voting in Large Electorates

Por • 25 dic, 2017 • Category: Opinion

We analyze Assessment Voting, a new two-round voting procedure that can be applied to binary decisions in democratic societies. In the first round, a randomly-selected number of citizens cast their vote on one of the two alternatives at hand, thereby irrevocably exercising their right to vote. In the second round, after the results of the first round have been published, the remaining citizens decide whether to vote for one alternative or to ab- stain. The votes from both rounds are aggregated, and the final outcome is obtained by applying the majority rule, with ties being broken by fair randomization.
