This contribution to the Common Knowledge symposium “Fuzzy Studies” reports on the rise of the “popular assemblies” movement that swept the streets of Madrid in the wake of the May 15, 2011, occupation of Puerta del Sol. Assemblies have since taken installation in public spaces as infrastructural with significant methodological implications. Their incorporation into the cityscape has demanded of participants an inventive deployment of techniques and tactics drawn from archival practices and practices of hospitality, as well as the development of (...) varieties of urban hardware. The “fuzz” or mess of the assembly — the difficulties that participants have at putting together, let alone understanding, the assembly as an urban form — offers a valuable perspective on present-day discussions concerning the city as an object of political claims and rights.

The aim of the present paper is to provide a logical reconstruction of the Marxian Theory of Value. This reconstruction is based upon the concept of abstract as opposed to that of homogeneous labor. Abstract labour is a social relation that holds in a market economy, (at least) whenever the profit rate is uniform; it consists in a comparison of the different labors through the exchange relationship. The author proved in a different place (see García de la Sienra, 1987) that (...) there exists a mathematical representation of abstract labor which is unique up to similarity transformations. The existence of this function — which is none other than the value function — is the basis of the present axiomatization, which includes detailed reconstructions of two of the most important models of the theory.

The aim of the present paper is to attack some of the conceptual problems that arise when the framework of mathematical learning theory is applied to the description of the behavior of the firm, in setting prices and production quotas, in a competitive market. The goal is to depict the process by which the firm fixes prices and production quotas as a stochastic learning process. A solution to such problems is proposed which is based on statistical-decision concepts. The conceptualization of (...) the behavior of the firm by means of concepts pertaining to mathematical learning theory gives rise to certain mathematical problems, which are formulated here in rather precise terms.

Durante la preparación del doctorado, Adolfo Posada entra en relación con don Francisco Giner y con el movimiento krausista cuya influencia fue decisiva en su formación espiritual y en su actitud ante la vida. Esta breve historia del krausismo español es un homenaje a los que fueron sus maestros, y aunque es posible que en algunos aspectos esté superada por estudios posteriores, tiene el interés de que ha sido escrita por una persona que vivió el movimiento krausista desde dentro.

It is still perhaps not widely appreciated that in 1905 Einstein used his postulate concerning the ‘constancy’ of the light-speed in the ‘resting’ frame, in conjunction with the principle of relativity, to derive numerical light-speed invariance. Now a ‘weak’ version of the relativity principle (or, alternatively, appeal to the Michelson—Morley experiment) leads from Einstein's light postulate to a condition that we call universal light-speed constancy. which is weaker than light-speed invariance. It follows from earlier independent investigations (Robertson [1949]; Steigler [1952]; (...) Tzanakis and Kyritsis [1984]) that this condition is none the less sufficient to derive the Lorentz transformations up to a scale factor, given the well-known kinematic principle of ‘reciprocity’. In this paper, we follow Robertson and explore the kinematics consistent with universal light-speed constancy without imposing reciprocity, and we recover the Lorentz transformations by further appeal only to the weak relativity principle and spatial isotropy.

Este artículo pretende mostrar la convivencia de dos estructuras de pensamiento en la escolástica española y, especialmente, en Suárez. Vitoria presenta una visión comunitaria del orden internacional y sus enseñanzas serán transmitidas a Suárez, quien, al contrario, presenta una visión societaria del orden internacional. Esta diferencia no es una casualidad, sino un auténtico cambio de paradigma en el sabio granadino, que hace de él un autor más próximo a la modernidad que a la tradición escolástica. Gracias a un estudio comparado (...) mostraremos el punto de inflexión que supone Suárez en el tránsito hacia la modernidad y su idea de un orden mundial fundado en una sociedad de Estados. (shrink)

Se reconstruye el discurso de la divulgación de la filosofía a través de un enfoque diacrónico que recoge las manifestaciones escritas, orales, audiovisuales y corporales dirigidas tanto a un público especializado como segmentos de población no especializado resaltando los valores que conformarían la comunicación pública de la filosofía en México así como sus líneas investigativas.

No Brasil, diversos grupos de pesquisa apresentam interesse em aprofundar a Educação em outros países latinoamericanos. A presente pesquisa forma parte do grupo “Filosofia e Educação” (Educogitans), Universidade Regional de Blumenau (FURB), Blumenau, Santa Catarina, Brasil, que tem interesse em aprofundar a problemática epistemológica educacional latino americana. Colômbia é um dos países com uma expressiva produção sobre a referida problemática. Assim, o objetivo da presente pesquisa é identificar e analisar algumas concepções de cientificidade no pensamento epistemológico da educação na Colômbia. (...) Visa aprofundar as concepções de Ciências da Educação por parte de autores colombianos. Também se aprofundará em como consideram o objeto da epistemologia e sua importância para a América Latina. Os dados foram coletados mediante os levantamentos bibliográficos e documentais e interpretados no contexto das perspectivas da epistemologia da Educação na América Latina. (shrink)
