The price of copper is unstable but it is considered an important indicator of the global economy. Changes in the price of copper point to higher global growth or an impending recession. In this work, the forecasting of the spot prices of copper from the New York Commodity Exchange is studied using a machine learning method, support vector regression coupled with different model schemas (recursive, direct and hybrid multi-step). Using these techniques, three different time series analyses are built and its (...) performance are compared. The numerical results show that the hybrid direct-recursive obtains the best results.

Recent developments in science and technology point to the need to unify, and extend, the definition of memory. On the one hand, molecular neurobiology has shown that memory is largely a chemical process, which includes conditioning and any form of stored experience. On the other hand, information technology has led many to claim that cognition is also extended, that is, memory may be stored outside of the brain. In this paper, we review these advances and describe the increasingly accepted extended (...) definition of memory. This definition is largely accepted in neuroscience but not explicitly stated. In the extended definition, memory is the capacity to store and/or retrieve information. Does this new definition of memory mean that everything is now a form of memory? We stress that memory still requires incorporation, that is, a corpore. It is a relationship -- where one biological or chemical process is incorporated into another, and changes both in a permanent way. Looking at natural and biological processes of incorporation can help us think of how incorporation of internal and external memory occurs in cognition. We further argue that, if we accept that there is such a thing as the storage of information outside the brain -- and that this organic, dynamic process can also be called “memory” -- then we open the door to a very different world. The mind is not static. The brain, and the memory it uses, is a work in progress; we are not now who we were then. (shrink)

Different theoretical approaches highlight the growing relevance of corporate reputation as strategic factor. Among these approaches the arguments of the Resource-Based View are special worthwhile (Grant, 1991, California Management Review33(3), 114–135; Barney, 1999, Sloan Management Review Spring, 137–145). Nevertheless, this topic poses several methodological problems (Barney et al., 2001), as the unavailability to identify and measure this organizational factor, that is “socially complex” and intangible in its nature. In this work, using the findings of our empirical research on Spanish biotechnology (...) firms, we carry out an identification and measurement of corporate reputation, highlighting its two key components: “business reputation” and “social reputation”.

There has recently been work by multiple groups in extracting the properties associated with cardinal invariants of the continuum and translating these properties into similar analogous combinatorial properties of computational oracles. Each property yields a highness notion in the Turing degrees. In this paper we study the highness notions that result from the translation of the evasion number and its dual, the prediction number, as well as two versions of the rearrangement number. When translated appropriately, these yield four new highness (...) notions. We will define these new notions, show some of their basic properties and place them in the computability-theoretic version of Cichoń's diagram. (shrink)

In the first half of this paper, we study the way that sets of real numbers closed under Turing equivalence sit inside the real line from the perspective of algebra, measure and orders. Afterwards, we combine the results from our study of these sets as orders with a classical construction from Avraham to obtain a restriction about how non trivial automorphism of the Turing degrees (if they exist) interact with 1-generic degrees.

El igualitarismo de la suerte es una teoría de justicia distributiva que incluye consideraciones de responsabilidad atributiva individual para definir las obligaciones distributivas. Se presenta como un intento de recomponer cierta consistencia interna a la teoría rawlsiana y evitar algunas de sus consecuencias “inequitativas”. El artículo defiende la consistencia interna del proyecto rawlsiano sin necesidad de incluir un criterio sensible a la responsabilidad atributiva individual, ya que la inclusión de tal criterio resultaría ilegítima desde el punto de vista rawlsiano.

En el presente artículo hago un resumen de «Esas Indias equivocadas y malditas» de Rafael Sánchez Ferlosio. La principal idea que desarrolla es que el discurso de los conquistadores, y hasta la actualidad muchos historiadores, legitimaba la conquista de América en nombre de la religión, de la civilización o del progreso; por ello, todo el dolor de las «naciones indias» estaría justificado por su incorporación a la historia universal. A continuación, presento los comentarios hechos por Juan Antonio Ruescas Juárez, María (...) del Mar Ramírez Alvarado y por Francisco Castilla Urbano a ese texto ferlosiano. Finalmente, concluyo con unas reflexiones personales sobre el texto de Sánchez Ferlosio. (shrink)

El objetivo de este artículo es explorar las relaciones entre la religión católica y la kultura en Timor-Leste desde una perspectiva histórica y antropológica. Pretendemos mostrar que la relación entre ambas se produce mediante una tensa coexistencia y que no se trata apenas de un sincretismo, resultado de la mezcla de elementos tomados de ambas. Para ello veremos cómo ambos regímenes de creencias se apropian de conceptos ajenos a su liturgia y los resignifican representándolos desde sus propios principios cosmovisvos. Veremos (...) también, mediante un análisis del discurso de un especialista ritual, cómo éste manipula activamente entidades no-humanas de ambos regímenes de creencias, reensamblándolos de un modo que le beneficia, con el objetivo de reforzar su posición en la jerarquía social. Así, mostramos cómo el análisis del enrolamiento de este tipo de entidades en el discurso se hace fundamental para entender los mecanismos de adquisición y distribución de poder en el país. (shrink)

Giacomo Zabarella es considerado uno de los aristotélicos más prestigiosos y más influyentes del siglo XVI. Su obra lógica, sus escritos sobre física y sus comentarios, publicados póstumamente, tuvieron un enorme impacto especialmente en las primeras décadas del siglo XVII, y sirvieron como verdaderos manuales con los que se formaron muchos universitarios europeos. Este artículo analiza la figura de Zabarella centrándose en su obra sobre física, el De rebus naturalibus libri XXX, editado en 1590, apenas unos días antes de su (...) muerte. (shrink)

La scommessa che anima il volume a c. di Sara Guindani e Alexis Nuselovici, come esplicitato nella prefazione, è la ricezione critica di un’eredità o – se così si può parafrasare – la messa in opera di un lascito. Notoriamente, “messa in opera” è espressione atta a evocare reminiscenze heideggeriane. Tuttavia, il più delle volte non si tiene in conto che Heidegger rende con “essere in lavorazione” – dunque in corso d’opera – l’ἐνέργεια aristotelica; v. il § 26 g dei (...) suoi Concetti fondamentali...

A distanza di quasi trent’anni dalla prima edizione garzantiana (marzo 1992), Castelvecchi ripubblica un classico di Garroni, Estetica. Uno sguardo-attraverso, arricchito da un’introduzione di Stefano Velotti. I principali temi affrontati nel testo in esame possono essere schematicamente divisi in due punti-chiave: il «dover essere del senso» e l’estetica come filosofia critica. Il «dover essere del senso», su cui molto insiste Garroni, riprende espressamente l’intuizione carabellesiana del «...

A partir de El Conocimiento del Amor, Martha Nussbaum emprendió un novedoso proyecto teórico, el de construir una vinculación productiva y no colonizadora entre la literatura y la reflexión moral. Una de las tesis que aúnan sus múltiples textos sobre este proyecto es que la lectura de textos literarios puede ser un componente no solo importante, sino necesario en el desarrollo moral de los sujetos. Por medio de una determinada forma de lectura y de un lector activo y crítico al (...) mismo tiempo, el sujeto podría desarrollar en mayor grado una capacidad empática que le permita reconocer injusticias, afectos y vulnerabilidades en situaciones allende la propia y en otros individuos (Nussbaum, 1997a, p. 111). El objetivo de esta presentación es contrastar esta tesis con un texto central de la literatura argentina moderna, El Juguete Rabioso2 de Roberto Arlt. Escritor, periodista e inventor, Roberto Arlt (1900-1942) es considerado como uno de los primeros escritores modernos de Argentina que incorporó materiales heterogéneos para su obra literaria –textos periodísticos, manuales químicos, etcetera– y que ofreció una interpretación particularísima de la vida urbana cambiante, desigual y políticamente movilizada de las primeras décadas del siglo XX. Construida como una novela de iniciación, el texto arltiano acompaña las desventuras existenciales de Silvio Astier, un joven marginado de los años 30 del siglo pasado que, a pesar de buscar el éxito a cada paso, solo encuentra el fracaso. El punto central de nuestro interés estará colocado en que el acto trascendental de su vida, una acción cruel y vil contra un amigo es llevada a cabo y justificada como producto de leer determinadas novelas literarias. La cuestión problemática de esta contrastación será cómo interpretar esta acción de Astier. ¿Es una refutación parcial de la tesis de Nussbaum, ya que las lecturas de Astier guían esta acción moralmente incorrecta?, ¿o es solo una advertencia contra las esperanzas exageradas de Nussbaum en la capacidad transformadora de la literatura?, ¿o, por el contrario, es una confirmación de la tesis, ya que esa acción no se seguiría del tipo específico de lectura que propone Nussbaum?, ¿o es, en este mismo sentido, una advertencia de que las condiciones capitalistas e individualistas representan obstáculos para el tipo de lectura que promueve Nussbaum?. En este artículo, defenderé que la interpretación más adecuada de la acción trascendental de Astier es que ella no surge de una experiencia lectora demasiado empática, sino de una experiencia lectora que rechaza la empatía, ya que implica la fusión total entre el personaje ficticio arltiano y aquellas novelas que conforman su experiencia literaria. La estructura del trabajo es la siguiente: En la primera sección, reconstruiré lo que Nussbaum denominó la promesa política de la literatura y cómo ella se basa en el mayor desarrollo de las capacidades empática y compasiva que puede ofrecer, en especial cuando se la compara con las teorías éticas generales tradicionales. En la segunda sección, confrontaré dos tipos de respuesta moralizante que la teoría de Nussbaum podría dar frente al “caso Astier” y mostraré que existe una respuesta no-moralizante y que refuerza la teoría de la filósofa.

The paper examines the connection between art and poiesis, moving from Aristotle’s Metaph. A 1 and Z 7-9. In particular, the analysis of those passages suggests dividing the genesis of artworks into noesis and poiesis. The noesis is the phase in which the artist plans in his mind the eidos (aspect) of the work that he is going to produce; the poiesis is the realization which actualizes – through its extrinsecation – the “aspect” mentally planned by the artist. After the (...) exposition of Aristotle’s theory, the related conceptual elements are developed, also having recourse to musical examples, in order to show the strict link between speculation and artistic praxis. The term enopé occurs in this part of the work as a metaphor which renders the peculiar form of presence of the work of art, whose essence emerges in the course of production. Moreover, a specific section is devoted to illustrating that ready-mades can be conciliated with the poietic nature of art. Finally, the paper focuses on performing (called «re-productive») arts, such as music; those forms of art include two poietic phases: the poiesis of the author (e. g., the composer) and the poiesis of the interpreter. The last paragraph considers the musical avant-gardes and explains that they confirm the poietic foundation of art, instead of denying it. (shrink)

Este articulo tiene como objetivo defender la necesidad de incluir la dimensión de la agencia política en un criterio de legitimidad democrático, especialmente si este es un criterio deliberativista. Para lograr tal objetivo se desarrolla un argumento intuitivo en el cual se muestra que si la agencia política no es considerada como relevante para la legitimidad democrática, podrían aceptarse como legítimos esquemas de decisión política que no requieran ningún grado significativo de participación política. Una vez demostrada esta necesidad, se muestra (...) que aunque el Enfoque de las Capacidades de Amartya Sen ha intentado mostrar la conexión intrínseca entre la dimensión de agencia y la democracia, su definición de la primera debe modificarse a fin de incorporar la agencia de los otros individuos de la sociedad como límite a los objetivos políticos. In this article, I defend the need to add the political agency dimension to the democratic legitimacy criterion, especially when it is a deliberativist criterion. In doing so, I develop an intuitive argument to show that if political agency is not deemed as relevant for the democratic legitimacy, some political schemes that do not require a significant degree of political participation will be accepted as legitimate at the end. Having shown this, I argue that although the Senian Capability Approach has tried to show the intrinsic connection between the political agency dimension and democracy, it lacks a precise definition of political agency, which should include the others' individual agency as a limit to the political objectives.

Anti-poverty policies and attitudes of distrust toward the needy share a long history. From the narratives of de Quevedo’s El Buscón, in which beggars are presented as able-bodied individuals making a concerted effort to take advantage of others, to the invasive physical tests and “workhouses” that were part of the English Poor Laws, the poor have long been regarded as deserving careful oversight. Although in increasingly subtle ways, this history continues as part of a popular set of policies in Latin (...) America called “Conditional Cash Transfers,” which make income support conditional on certain behavioral changes. This paper argues that this resumption in recent times is normatively problematic because it harms the beneficiaries’ self-esteem, leading to stereotypes and sociological errors that reproduce social hierarchies. Alternatively, the paper advances a comparative defense of Basic Income on the basis of its lesser-known affinity with non-discriminatory attitudes. (shrink)

University research in the U.S.A. is based on a tight relationship between University and economic activity. In Europe and South America, although less commonly than in the U.S.A., there's already a large amount of experiences related to the creation of "on campus" or "spin off" companies based on the results and knowledge obtained from research in University departments and R&D centres financed with public funds. The virtual base of this results in communication technologies enables private use and the appropriation of (...) the benefits by their authors. European model, historically widely separated from private companies, has produced high quality basic research, but it has failed to obtain profit from technological development. Research funds happen to be basically public. Europe heads for economic, politic and military union. Common economic space and the growing up of the new markets, which we can foresee to be extended to other countries, will promote business opportunities and the relationship University-Industry. University institutions and faculties should think about their current ethic convictions to create a new Industry-University model in the context of a global economy. (shrink)

How has the storage of information shaped human cognition? We bring together current advances in cognitive science, the neurobiology of memory, and archaeology to explore how storage of information affects consciousness. These fields strongly suggest that the increase in storage of information in the environment – which we call exosomatic storage of information – may have led to changes in human consciousness and human neurophysiology over time. To bring these findings together conceptually, we develop what we call a dialectical model (...) of the relationship between storage of information and the development of human consciousness. Using the system of dialectic philosophy, we put forward that (a) environmental changes, consciousness, and neurophysiology develop together, (b) these changes were irreversible, (c) quantitative increases in exosomatic storage of information may have led to qualitative changes in human consciousness and neurophysiology, (d) these changes in turn affected how we see ourselves. Indeed, our capacity to store information exosomatically distinguishes us from other animals, and may be a key attribute of our self-awareness and therefore self-consciousness. Because metaphors are central to human thought and can help structure scientific inquiry, we illustrate our model using a metaphor of drops of silver on the back of a glass, eventually making a mirror—where successive quantitative change leads to an irreversible qualitative development in human consciousness. The dialectic model can offer new insights into the co-evolution of material culture and human beings through its broader philosophical foundations and explanatory power. (shrink)

This article presents the ethical concept of service as a way of specifying higher ethical principles in business practice. We set out from the work of a number of scholars who have found some shared ethical principles for doing business in a context of cultural diversity. Love, benevolence, consideration, and other related concepts are considered to be important guiding concepts for business but it is not clear how they are to be operationalized. We argue that the ethical concept of service (...) can act as a bridge for bringing those higher principles into business practice. The article explains and refines the ethical concept of service, which has received little attention. In particular, we address the ethical ambiguity implicit in the common meaning of service, explain how service shows love in business, and offer an account of how service provides ethical growth through virtue. Finally, this work presents a variety of examples from business which illustrate how the ethical concept of service can be put into practice. To achieve the aim of this study we draw inspiration from Catholic social teaching. This source provides useful insights into service and can be understood and accepted without requiring that particular faith. (shrink)

_The Dead Mother_ brings together original essays in honour of André Green. Written by distinguished psychoanalysts, the collection develops the theme of his most famous paper of the same title, and describes the value of the dead mother to other areas of clinical interest: psychic reality, borderline phenomena, passions and identification. The concept of the 'dead mother' describes a clinical phenomenon, sometimes difficult to identify, but always present in a substantial number of patients. It describes a process by which the (...) image of a living and loving mother is transformed into a distant figure; a toneless, practically inanimate, dead parent. In reality, the mother remains alive, but she has psychically 'died' for the child. This produces a depression in the child, who carries these feelings within him into adult life, as the experience of the loss of the mother's love is followed by the loss of meaning in life. Nothing makes sense any more for the child, but life seems to continue under the appearance of normality. _The Dead Mother_ is a valuable contribution to literature on psychoanalytic and psychotheraputic approaches to grief, loss and depression.

La versión seniana del enfoque de las capacidades define a la libertad individual en términos de la posesión de una preferencia decisiva. A través del análisis de la discusión con la definición provista por el republicanismo, se mostrará que la primera desconoce el papel que las instituciones deben jugar a la hora de proteger esas libertades y que, por lo tanto, es inadecuada. En este artículo se argumenta que, cuando esta definición es considerada dentro del marco más general del pensamiento (...) seniano, es posible hallar una solución a tales problemas, y que ella consiste en vincular las libertades con una concepción deliberativa de la democracia. Sin embargo, se mostrará que esta solución tiene costos teóricos y que parte de esa definición de la libertad o bien debe abandonarse o bien relativizarse. Senian Version of the Capability Approach defines individual freedom in terms of having a decisive preference. Through the analysis of the discussion with the definition provided by republican conceptions, it will be shown that Senian definition ignores the role that institutions should play at protecting those freedoms and that this is a reason to consider it inadequate. This article argues that, when this definition is considered in the more general framework of Senian thinking, a solution can be founded. This solution consists in the construction of a solid link between freedom as decisive preference and a deliberative conception of democracy. However, it will be argued that this solution has some theoretical costs and that part of that definition should be given up or at least relativized. (shrink)

Una característica indiscutible de la amistad es la confianza: los amigos confían entre sí contándose secretos y ayudándose especialmente cuando existen riesgos de que algo vaya mal. Este artículo investiga la naturaleza de esa confianza.

Para mostrarlo, se ofrecerán tres razones obtenidas del análisis de la fenomenología (...) de la traición, es decir, cuando la confianza ha sido destruida. (shrink)

Resumen: Este artículo analiza la fundamentación normativa de un tipo de políticas de alivio contra la pobreza comunes durante los últimos años en Latinoamérica, a saber, las transferencias monetarias condicionadas. Se mostrará que la justificación típica de las transferencias monetarias condicionadas es ilegítima en una comunidad política democrática. A través de la indagación de las razones por las que la carga de la prueba se coloca del lado de las transferencias incondicionadas, se mostrará que se apela a una noción controvertida (...) de responsabilidad individual que cristaliza relaciones desiguales y que se basa en un diagnóstico empírico cuestionable.: This paper analyzes the normative foundations of conditional cash transfers, a kind of poverty relief policy which has been massively implemented during recent years in Latin America. I intend to show that the conditional cash transfer’s typical justification is illegitimate for a democratic political community. After reviewing the reasons why the burden of proof falls on unconditional transfers, I argue that the typical justification appeals to a controversial conception of individual responsibility that crystallizes unequal interpersonal relations and is based on a shaky empirical diagnosis.

El noûs poie-tikós de Aristóteles ha sido objeto de innumerables estudios y debates a lo largo de la historia de la filosofía. Este artículo trata sobre la visión que de él tiene el aristotélico renacentista P. Pomponazzi, célebre, entre otras cosas, por suscitar una agria polémica con su tesis de que la razón natural no ofrece argumentos que puedan sostener la inmortalidad del alma. Esta tesis tiene que dar respuesta, sin embargo, a aquellos textos aristotélicos que hablan de la inmaterialidad (...) e inmortalidad del intelecto. El autor estudia esta respuesta de Pomponazzi en el contexto de los elementos más importantes de su psicología. (shrink)
