Increased concern for the environment has increased the number of investment opportunities in mutual funds specialized in promoting responsible environmental attitudes. This article examines the performance and risk sensitivities of US green mutual funds vis-à-vis their conventional peers. We also analyze and compare this performance relative to other socially responsible investing (SRI) mutual funds. In order to implement this analysis, we apply a CAPM-based methodology and find that in the 1987–2009 period, environ- mental funds had lower performance than conventional funds (...) with similar characteristics. However, if we focus on a more recent period (2001–2009), green funds achieved adjusted returns not significantly different from the rest of SRI and conventional mutual funds. (shrink)

Behavioral interventions have shown promising neuroprotective effects, but the cascade of molecular, brain and behavioral changes involved in these benefits remains poorly understood. Projecte Moviment is a 12-week multi-domain, single-blind, proof-of-concept randomized controlled trial examining the cognitive effect and underlying mechanisms of an aerobic exercise, computerized cognitive training and a combined groups compared to a waitlist control group. Adherence was > 80% for 82/109 participants recruited. In this study we report intervention-related changes in plasma biomarkers and structural-MRI and how they (...) related to changes in physical activity and individual variables and their potential role as mediators in the cognitive changes. Our results show that although there were no significant changes in molecular biomarker concentrations in any intervention group, changes in ICAM-1 and SDF1-α were negatively associated with changes in physical activity outcomes in AE and COMB groups. Brain volume changes were found in the CCT showing a significant increase in precuneus volume. Sex moderated the brain volume change in the AE and COMB groups, suggesting that men may benefit more than women. Changes in molecular biomarkers and brain volumes did not significantly mediate the cognitive-related benefits found previously for any group. This study shows crucial initial molecular and brain volume changes related to lifestyle interventions at early stages and highlights the value of examining activity parameters, individual difference characteristics and using a multi-level analysis approach to address these questions.

El presente artículo se propone pensar las consideraciones sobre el olvido que Nietzsche lleva a cabo, principalmente en su Segunda consideración intempestiva, desde una perspectiva ontológica, lo cual implicará llevar a cabo esta tarea tomando como guía la lectura heideggeriana de Nietzsche. Ésta supone, por un lado, reconocer la polisemia del fenómeno del olvido y por el otro, reflexionar en la íntima relación que existe entre conceptos fundamentales de la filosofía nietzscheana tales como: vida, olvido y voluntad de poder. Comprender (...) dichos términos desde una perspectiva ontológica implicará retrotraerlos hasta su estatuto originario. (shrink)

Las frutas y hortalizas han sido siempre noticia debido principalmente a sus propiedades beneficiosas para la salud. Sin embargo, cada vez más ocupan titulares debido a su implicación en toxiinfecciones alimentarias. Por este motivo, desde 2008, las frutas y hortalizas frescas son consideradas por muchos organismos internacionales como un alimento de riesgo. Uno de los principales problemas microbiológicos de las hortalizas de hojas son las bacte­rias entéricas que pueden adherirse rápidamente al tejido durante el cultivo, coexistir con las bacterias epífitas (...) y persistir por largos periodos de tiempo. La prevalencia de microorganismos patógenos en las frutas y hortalizas es baja y la cuantificación de las bac­terias patógenas o de microorganismos indicadores generalmente muestra niveles muy bajos, lo que no justificaría el elevado número de alertas microbiológicas asociadas a este tipo de productos. Sin embargo, existen dudas sobre si los recuentos obtenidos utilizan­do las técnicas convencionales son capaces de reflejar realmente todos los microorganismos presentes en el producto vegetal, así como en el agua de riego y en el suelo. Varios estudios han demos­trado que cuando las bacterias son sometidas a distintos factores de estrés entran en un estado temporal de baja actividad metabóli­ca en el cual las células pueden persistir durante largos periodos de tiempo sin división celular, llamado estado de latencia o viable pero no cultivable. La relevancia que el estado fisiológico de las bacterias puede tener en el desarrollo de toxiinfecciones alimenta­rias causadas por las frutas y hortalizas es un tema de gran interés que está atrayendo más y más la atención de los investigadores.

In this paper we mainly study preservation theorems for two fragments of the infinitary languagesLκκ, withκregular, without the equality symbol: the universal Horn fragment and the universal strict Horn fragment. In particular, whenκisω, we obtain the corresponding theorems for the first-order case.The universal Horn fragment of first-order logic (with equality) has been extensively studied; for references see [10], [7] and [8]. But the universal Horn fragment without equality, used frequently in logic programming, has received much less attention from the model (...) theoretic point of view. At least to our knowledge, the problem of obtaining preservation results for it has not been studied before by model theorists. In spite of this, in the field of abstract algebraic logic we find a theorem which, properly translated, is a preservation result for the strict universal Horn fragment of infinitary languages without equality which, apart from function symbols, have only a unary relation symbol. This theorem is due to J. Czelakowski; see [5], Theorem 6.1, and [6], Theorem 5.1. A. Torrens [12] also has an unpublished result dealing with matrices of sequent calculi which, properly translated, is a preservation result for the strict universal Horn fragment of a first-order language. And in [2] of W. J. Blok and D. Pigozzi we find Corollary 6.3 which properly translated corresponds to our Corollary 19, but for the case of a first-order language that apart from its function symbols has only oneκ-ary relation symbol, and for strict universal Horn sentences. The study of these results is the basis for the present work. In the last part of the paper, Section 4, we will make these connections clear and obtain some of these results from our theorems. In this way we hope to make clear two things: (1) The field of abstract algebraic logic can be seen, in part, as a disguised study of universal Horn logic without equality and so has an added interest. (2) A general study of universal Horn logic without equality from a model theoretic point of view can be of help in the field of abstract algebraic logic. (shrink)

Este trabajo analiza la posición de la educación y el Estado en la filosofía práctica de Immanuel Kant, paraquien la educación se establece como la tarea esencial de la humanidad, no en vano señaló que, “el hombre puedeconsiderar cómo los descubrimientos más difíciles, el arte del gobierno y el arte de la educación”, que es con lacual inicia el proceso por el cual el ser humano se hace humano a saber; el de la civilización y la cultura, elementosintrínsecos en la (...) esfera de la educación que es la base del desarrollo de las personas en particular, y de la humanidaden general, por lo cual las tesis sobre educación en el texto de la pedagogía deben ser revisadas, sugiriendo que elproyecto educativo cosmopolita es la mejor vía para propiciar una educación que tienda al bien universal.Sin embargo, para que la propuesta kantiana sea impulsada desde las instituciones educativas, se requierereplantear la tarea y función no solo de los padres, sino también del Estado en la esfera educativa y orientarla segúnlos parámetros del cosmopolitismo, una filosofía que se ofrece como un deber ineludible y como una necesidadsocial generalizada. La definición de educación cosmopolita se presenta como un método de crecimiento humano que posibilita la identificación de seres con personalidad moral y jurídica en cada uno de nosotros. (shrink)

Este texto presenta las claves fundamentales del pensamiento de Fernando Rielo (1923-2004). Destaca, de forma general, su optimismo epistemológico frente al quehacer filosófico, junto con su afán pedagógico en la transmisión de su filosofía y sus propuestas metafísicas. No obstante, el lenguaje rieliano es de especial interés y suscita algunos debates interesantes que serán abordados en profundidad.

RESUMEN El artículo examina el origen del proyecto rortiano de acabar con la imagen única de Platón. En su escrito autobiográfico, Trotsky las orquídeas silvestres, Rorty describe su trayectoria filosófica y presenta su alternativa a Platón como pensada desde su más pronta juventud. Sin embargo, como vamos a mostrar, el proyecto central de acabar con la imagen única de Platón no es algo que esté pensado ni se dé desde un principio en sus obras. Defendemos que, pese a lo que (...) el propio Rorty indicó en sus escritos, encontramos indicios de que no es hasta la década de los noventa que Rorty piensa en elaborar una nueva relación alternativa al léxico último de Platón. ABSTRACT The article examines the origin of the rortyan project to destroy Plato's unique image. In his autobiographical writing, Trotsky the Wild Orchids, Rorty describes his philosophical journey and presents his alternative to Plato as thought out from his earliest youth. However, as we will show, the central project of ending Plato's unique image is not something that is thought out or given from the beginning in his works. We argue that, despite what Rorty himself indicated in his writings, we find indications that it is not until the 1990s that Rorty thinks of elaborating a new alternative relationship to Plato's last lexicon.

This study analysed the effects a values education programme can have on the feelings of self‐realisation, self‐concept and self‐esteem of Romany adolescents in southern Spain. To do this, an experimental group received a values education intervention but a control group did not. The intervention programme was adapted to the Romany culture. The self‐realisation, self‐concept and self‐esteem of both groups were evaluated using the Self‐Concept and Realisation Questionnaire. Statistical analyses showed the existence of significant differences between the experimental and control groups (...) on the variables studied. Based on the results, we suggest that a values education programme like this, that has been culturally adapted, can make a positive impact on the self‐realisation of young people from a marginalised community.

En la primera parte del Teeteto Sócrates refuta tres tesis que considera estrechamente vinculadas entre sí: la tesis de Teeteto que identifica conocimientoy percepción, la tesis relativista y la tesis movilista. El propósito de este trabajo es mostrar que en tres de las refutaciones ofrecidas contra estas posiciones se exhibe una misma estrategia tendiente a remitis a un prerrequisito dialéctico vinculado a la pretensión de verdad. ESta constituiría una estrategia radical, en el sentido de que pone en cuestión la misma (...) posibilidad de enmitir la propia tesis por parte del adversario. (shrink)

In the opening years of the 21st century, it became fashionable to describe the human genome as belonging to the common heritage of humanity. The United Nations, in its Universal Declaration on the Human Genome and Human Rights, now identifies the human genome as part of the common heritage, as does the international Human Genome Organization and the Council of Europe. The common heritage concept has played a prominent role in arguments against patenting the human genome or portions thereof. This (...) essay considers whether the common heritage designation will advance the political and legal goals of its proponents. (shrink)

Peirce claims that there is but one primary logical relation, that of illation or logical consequence. The present paper is devoted to show the influence of this viewpoint in Peirce's conception of logic. After a brief presentation of Peirce's membership in the tradition of language as calculus, it examines his pioneering work in modal logic and other systems of logic. The last section attemps to summarize his doctrine of logic as a normative science.

This article aims to clarify the relationship between the Truth and Justification in the philosophies of Jürgen Habermas and Richard Rorty from their discussions. The thesis that I advocate is that the relationship between Truth and Justification depends on the Ontological and Epistemological assumptions that each maintains and is not a matter of conditions of speech as stated by Habermas.

Information from forensic genetic tests of crime scene samples has been used to make claims about suspects' race and appearance. This article discusses and critiques the techniques used to make such claims, and raises policy concerns about them.

When addressing the first principles of the science of the being and physics, Aristotle presents a special kind of proof in favor of the principle of non-contradiction and the principle of movement. This paper explores the nature of such proofs and tries to show important parallels between them. Indeed, in both cases Aristotle makes use of dialectical arguments which aim to demonstrate that whoever denies these principles necessarily assumes a series of commitments related to language that involve the very principles (...) in question. It is thus shown to what extent the principles which are discussed are a condition of possibility of the discourse itself. Thus, both series of arguments exhibit transcendental aspects, which, especially regarding disputes with the monist, have been often overlooked, and which illustrate the scope of dialectics when it comes to opening the way towards the first principles.

The present global financial crisis has revived the notion that competitive markets may lead some directors and executives to behave in opportunistic ways considered unethical and even illegal, through the pursuit of self-interest. This article proposes and tests an integrated model that offers new insights into the relationship between board structure, independence and firm value. By incorporating the proportion of independent directors on the board as a moderating factor in this relationship, this study contributes to a better understanding of the (...) entrenchment and convergence-of-interests hypotheses. Using empirical data obtained from 114 Spanish listed companies in a context of economic crisis, from 2007 to 2010, we conclude that having a board with a greater proportion of independent directors reduces the negative association existing between firm value and a large board size and significant board share ownership.

Parece incompatible escribir sobre reinserción social y alternativas a la prisión y no comenzar recordándonos el artículo 25.2 de la Constitución Española: "las penas privativas de libertad y las medidas de seguridad estarán orientadas hacia la reeducación y reinserción social y no podrán consistir en trabajos forzados". Y es imprescindible recordárnoslo en un momento en que se cuestiona la viabilidad de la reeducación y la reinserción social de las personas condenadas. Seguir creyendo en ella parece que nos vincula a colectivos (...) utópicos [recientemente, impartiendo un curso a miembros de la Policía Local de Madrid, me comentaban irónicamente que estas cosas son para los curas�] o para aquello que, dotados de unas grandes dosis de paternalismo siguen creyendo en la perfectibilidad del ser humano.

Desde que Asín Palacios publicó su estudio pionero sobre Ibn Masarra a partir de las fuentes indirectasdisponibles, proponiendo que su pensamiento estaba inspirado en los escritos del Pseudo-Empédoclesárabe y que había sido el introductor de la filosofía en al-Andalus, seinició el debate al respecto. El hallazgo de dos de las obras del autor cordobés ha dado una nueva orientacióna la polémica. En este artículo se revisan algunos aspectos fundamentales del debate sobre la «reconstrucción» del pensamiento masarrí realizada por Asín, cuestionando (...) el supuesto influjo del Pseudo-Empédocles, y se analiza el texto de Ibn ÔArabı¯ de Murcia que inspiró la asociación entre la imagen delas cinco columnas atribuida a Ibn Masarra y los cinco principios del Pseudos-Empédocles.Since Asín Palacios first published his pioneering study on the Andalusian thinker Ibn Masarra, basedon indirect sources, there has been an intense debate on some of his conjectures: he proposed that Ibn Masarrawas influenced by the writings of the so-called Pseudo-Empedocles and he introduced Philosophy in al-Andalus. The discovery of two unknown works by the author provideda new framework for discussion. The present article examines Asín’s «reconstruction» of Ibn Masarra’sthought, analysing the theory of the Pseudo-Empedocles influence, as well as a text by Ibn ÔArabı¯ which inspired the association of the image of the five pillars attributed to Ibn Masarra with the five principles of the Pseudo-Empedocles.
