La ciudad de Antigua, en Guatemala, ha sido y continúa siendo evocada a través de la palabra diluida en la historia y la memoria. Prueba de ello es el libro Poesía-documento, titulado Antigua Luna (2017), de la escritora costarricense Magda Zavala, publicado en 2017 por la editorial Letra Maya, dentro de la Colección Kayab, en Costa Rica. Este poemario, dividido en tres secciones; I. Capital de los Confines, II. Espacios y voces y III. La visitante, recoge entre sus versos (...) los resabios coloniales de un pasado épico, que convive con un presente transnacional y postmoderno. Ahí es donde los cimientos indígenas sostienen identidades en permanente reconstrucción, aprendida a través de cinco siglos de sobrevivencia en la desigualdad. (shrink)

There are compelling reasons to believe that musical works are abstract. However, this hypothesis conflicts with the platitude that musical works are appreciated by means of audition: the things that enter our ear canals and make our eardrums vibrate must be concrete, so how can musical works be listened to if they are abstract? This question constitutes the audibility problem. In this paper, I assess Julian Dodd’s elaborate attempt to solve it, and contend that Dodd’s attempt is unsuccessful. Then I (...) discuss what I take to be the ideal response to the audibility problem, and show that it ultimately fails. I contend, consequently, that the project of construing musical works as audible is disheartening. Accordingly, in my last section, I will argue the audibility problem may be satisfactorily resolved without ascribing audibility to musical works. (shrink)

Se explora la relación entre las dimensiones proposicional y no proposicional de la creencia religiosa para mostrar que la última dirige el proceso de justificación y representa su límite. Se defiende que la no proposicional también tiene valor cognitivo, porque constituye una suerte de elección epistémica preteórica que no es exclusiva de la fe religiosa. Se explora la noción de ambigüedad religiosa, tanto a nivel intelectual como experiencial, y se sostiene que la relación entre la dimensión proposicional y la no-proposicional (...) de la fe está mediada por la función directiva de las presuposiciones metafísicas instauradas por la experiencia religiosa.

About one third of patients with epilepsy have seizures refractory to the medical treatment. Electrical stimulation mapping is the gold standard for the identification of “eloquent” areas prior to resection of epileptogenic tissue. However, it is time-consuming and may cause undesired side effects. Broadband gamma activity recorded with extraoperative electrocorticography during cognitive tasks may be an alternative to ESM but until now has not proven of definitive clinical value. Considering their role in cognition, the alpha and beta bands could further (...) improve the identification of eloquent cortex. We compared gamma, alpha and beta activity, and their combinations for the identification of eloquent cortical areas defined by ESM. Ten patients with intractable focal epilepsy participated in a delayed-match-to-sample task, where syllable sounds were compared to visually presented letters. We used a generalized linear model approach to find the optimal weighting of each band for predicting ESM-defined categories and estimated the diagnostic ability by calculating the area under the receiver operating characteristic curve. Gamma activity increased more in eloquent than in non-eloquent areas, whereas alpha and beta power decreased more in eloquent areas. Diagnostic ability of each band was close to 0.7 for all bands but depended on multiple factors including the time period of the cognitive task, the location of the electrodes and the patient’s degree of attention to the stimulus. We show that diagnostic ability can be increased by 3–5% by combining gamma and alpha and by 7.5–11% when gamma and beta were combined. We then show how ECoG power modulation from cognitive testing can be used to map the probability of eloquence in individual patients and how this probability map can be used in clinical settings to optimize ESM planning. We conclude that the combination of gamma and beta power modulation during cognitive testing can contribute to the identification of eloquent areas prior to ESM in patients with refractory focal epilepsy.

As a thinker whose work proposes the recovery in Darwin of an innovative anthropology, which no specialist scholar has consistently refuted or has exposed as amounting to a forced or willful interpretation, Patrick Tort can enable us to arrive at a valid assessment of Darwin’s discourse on man and on civilization. In this regard, he underlines the unquestionably dialectical character of the passage from “nature” to “culture” in the project. As a consequence of their ignorance of this innovation, Marx, and (...) those who came after him, equated Darwinism with a Malthusian ideology and a doctrine of social selection, a position which Darwin precisely did not adopt, in his explanation of the origin and transformation of civilization, without however having to break with his selective biology. In the history of Marxism, the consequence of this epistemological faux-pas has been the interminable reiteration of “monist” problems in pursuit of a dialectical conceptualization of the links and the distinctions to be teased out between nature and civilization, materialism and morality. With a view to reestablishing a fruitful theoretical dialogue between the heritage of Marx and that of Darwin, a detour by way of Kant and his categorical moral imperative is certainly not desirable. The path leading to an overcoming of the contradictions is rather to be located by way of Marxism’s acknowledgement of the notion of “reversive continuity”, thus enabling us to conceptualize, in a unitary mode and from the perspective of materialism, the paradox of the extinction of struggle, within the horizon of the struggle of which nature constitutes the field of experimentation.

Corporate social responsibility has become a much-discussed subject in the business world. The Internet has become one of the main tools for CSR information disclosure, allowing companies to publicise more information less expensively and faster than ever before. As a result, corporations are increasingly concerned with communicating ethically and responsibly to the diversity of stakeholders through the web. This paper addresses the main question as whether CSR information disclosure on corporate websites is influenced by country of origin and/or industry sector. (...) Analysing the websites of 127 corporations from emerging countries, such as Brazil, Chile, China, India, Indonesia, Mexico, Thailand and South Africa, it becomes evident that both country of origin and industry sector have a significant influence over CSR information disclosure on the web . Based on the data studied, country of origin has a stronger influence over CSRIDOW than industry sector. (shrink)

This paper argues that the historical character of our knowledge is compatible with both ontological and epistemological realism. The first part critically analyses the thesis according to which the situated nature of our cognitive practices implies that they do not refer to an extra-linguistic reality. The second section explores the claim that realism is a necessary presupposition of our communicative practices and the final part outlines the principles of a pluralist realism.

Se ha impuesto la imagen del código de barras para hacer referencia a una secuencia de ADN mitocondrial que es utilizada para medir la distancia genética entre poblaciones animales. Según la interpretación esencialista de esta analogía, este método de medición serviría, por sí mismo, no solo para la rápida identificación de ejemplares, o muestras fragmentarias, de especies previamente clasificadas, sino también para el descubrimiento de nuevas especies. Los taxónomos integrativos han rechazado este último uso del método del código de barras (...) de ADN, dado que la complejidad biológica impide aplicarlo con precisión en eventos de especiación recientes. Argumentaré, sin embargo, que el método falla por razones conceptuales y no meramente empíricas. Aunque no existiera ese impedimento empírico, el código de barras de ADN no podría ser un método de descubrimiento de especies. (shrink)

Daniela Serna investiga y crea sobre el tránsito que se produce entre el objeto verbal de origen literario y el artefacto visual de carácter plástico y estético. Su obra expande la idea de la literatura formal, donde las dimensiones temporales y sensoriales se experimentan en la imaginación del lector, para proponer poemas visuales en los cuales propicia una experiencia de sentido que amplifica o diluye los límites de lo posible. En esta reseña se abordan un conjunto de obras, cuyo eje (...) central permite múltiples lecturas, tamizadas por una reserva de signos ideológicos, políticos y estéticos en los cuales la artista inscribe su obra, y que permiten interrogar la relación entre el mundo ficcional representado y la representación que el lector/espectador realiza.

The past decade has seen an explosion of work on calculi of explicit substitutions. Numerous works have illustrated the usefulness of these calculi for practical notions like the implementation of typed functional programming languages and higher order proof assistants. It has also been shown that eta-reduction is useful for adapting substitution calculi for practical problems like higher order unification. This paper concentrates on rewrite rules for eta-reduction in three different styles of explicit substitution calculi: λσ, λse and the suspension calculus. (...) Both λσ and λse when extended with eta-reduction rules, have proved useful for solving higher order unification. We enlarge the suspension calculus with an adequate eta-reduction rule which we show to preserve termination and confluence of the associated substitution calculus and to correspond to the eta rules of the other two calculi. We prove that λσ and λse as well as λσ and the suspension calculus are non-comparable while λse is more adequate than the suspension calculus in simulating one-step beta-reduction. After defining the eta-reduction rule in the suspension calculus, and after comparing these three calculi of explicit substitutions , we then concentrate on the implementation of the rewrite rules of eta-reduction in these calculi. We note that it is usual practice when implementing the eta rule for substitution calculi, to mix isolated applications of eta-reduction with the application of other rules of the corresponding substitution calculi. The main disadvantage of this practice is that the eta rewrite rules so obtained are unclean because they have an operational semantics different from that of the eta-reduction of the λ-calculus. For the three calculi in question enlarged with adequate eta rules we show how to implement these eta rules. For the λse we build a clean implementation of the eta rule and we prove that it is not possible to follow the same approach for the λσ and λsusp. (shrink)

Abstract:This article theorizes the disruptive epistemic work performed by microcosms in recent eco-fiction. Contemporary fiction often explores large-scale ecological disruption through smaller organisms and environments, enabling readers to perceive the Earth through analogy, allegory and metaphor. Within and against this scale-free reading, I argue that the microcosm has become a fracturing trope that troubles relations between scales. Drawing on fiction by T. C. Boyle, A. S. Byatt, Amitav Ghosh, Ali Smith, and Karen Tei Yamashita, I read the microcosm as a (...) critical tool of Anthropocene awareness, because it foregrounds and questions scalar collapse–the epistemic projection of one scale onto another.

How can law ethically regulate a future of fast-changing technologies? From recent inventions to science fiction, Future Law explores how law, ethics and regulation must respond to new technologies that challenge the boundaries of our ethics.

This paper makes the claim that the overall structure of Plato’s Laws follows the principle of indirect access to the knowledge of human soul, which consists in the understanding that a philosophical approach to the soul is only possible initially through an image of it. The structure of the Laws can be interpreted as a movement towards the soul’s interior, beginning with the famous image of the puppet. According to this image, the movement opens with the analysis of the non-rational (...) elements of the soul, which are capable of an harmonic relation with the rational element, and advances bit to bit to the rational or epistemic element. The political necessity of undertaking the dialectical investigation in order to attain a philosophical knowledge of the human soul and its specific excellence appears only at the end of the dialogue. In this way, the structure of the Laws dramatizes the progressive birth of philosophy, conceived as the dialectical investigation of the unity of virtue, starting from the initial understanding of the human soul contained in the myth of the puppet.

PurposeThe purpose of this paper is to investigate how public policies may influence the way members of virtual communities linked with social movements perceive the legitimacy of their leaders and governance structures.Design/methodology/approachThis paper is based on qualitative research with three Brazilian environmental education virtual communities. It adopts an interpretive approach, grounding the analysis in institutional theory.FindingsThe paper shows that a public policy of funding the studied communities has reinforced the legitimacy of some leaders and legitimated more centralised decision‐making structures. The (...) influence of the funding has endured even after the end of the respective contracts.Research limitations/implicationsAlthough the paper is limited to three virtual communities in a very specific context, its conclusions may inform other studies on the institutional instruments governments may appropriate to influence the virtual interactions among members of social movements and civil society organisations and which impact their offline interactions as well.Practical implicationsThe paper calls attention to the need to discuss public policies with stakeholders, especially to permit social movements and civil society organisations to have a say in policies that may affect their social structures.Originality/valueThe paper contributes to understanding how public policies impact interactions in virtual environments and in a broader sense, and the relevance of considering the influence of institutions in online interactions.

El arquitecto sevillano Fernando Rosales, cuya vida profesional se desarrolló a caballo entre los siglos xviii y xix, fue uno de los más activos maestros mayores de obras de la Iglesia de Sevilla. De carácter afable, tuvo sin embargo algunos sonoros desencuentros con el arquitecto José Echamorro, que aquí se exponen. Y al igual que ocurrió a sus compañeros en el cargo, la Real Academia de San Fernando rechazó sus proyectos enviados a dicha institución. Eclipsada por la de Antonio de (...) Figueroa y José Álvarez, el estudio monográfico de su obra está aún por abordar. Este trabajo pretende contribuir a su conocimiento, mediante la aportación de numerosas noticias inéditas, tanto biográficas como profesionales, algunas de las cuales subsanan persistentes errores historiográficos, contextualizándolas entre sus más conocidas realizaciones.

José Álvarez fue uno de los más activos maestros mayores de obras de la archidiócesis sevillana del XVIII. Contemporánea de Pedro de Silva, Ambrosio y Antonio de Figueroa y Fernando Rosales, alternó los encargos del Cabildo eclesiástico con los del Arzobispado, siendo estos últimos los que le otorgaron mayor prestigio. Basta citar algunos de los templos que construyó para comprender la magnitud de sus realizaciones. Sorprendentemente, su obra no había merecido aún la edición de una monografía, debido quizá a la (...) falta de noticias biográficas más allá de la de su origen onubense. Este trabajo pretende subsanar dicho vacío, documentando por vez primera su nacimiento y fallecimiento, su reducido círculo familiar, su autoría sobre relevantes obras eclesiales y repasando cronológicamente su actividad profesional. Todo ello para poner en valor la figura de uno de los grandes nombres de la arquitectura tardo-barroca sevillana. (shrink)

El objetivo de esta investigación es contribuir al conocimiento de la obra arquitectónica legada por el nieto de Leonardo de Figueroa al servicio de la diócesis hispalense, particularizando el estudio en la barroca Écija. Antonio de Figueroa, mal conocido como Antonio Matías, a pesar de ser el más prolífico maestro mayor del arzobispado en la segunda mitad del siglo XVIII, no ha merecido el debido interés por parte de la historiografía, manteniéndose hasta nuestros días diversas incógnitas sobre su obra, algunas (...) de las cuales se ponen de manifiesto en la ciudad astigitana. Al efecto de aclararlas, se documentan aquí sus intervenciones en cinco de las parroquias, destacando el inédito proyecto de Antonio de Figueroa para la realización del cuerpo de iglesia y capilla sacramental de Santa María, culminando la obra iniciada por su padre Ambrosio. El estudio se completa con la aportación de otros datos novedosos, referidos tanto al maestro como al proceso constructivo de los referidos templos. (shrink)

Tras décadas de deterioro de sus elementos exteriores, el sevillano templo de San Bartolomé ha visto por fin iniciada la restauración del más significativo de ellos, que no es otro que su esbelta e inacabada torre. Sobre la singular atalaya, compuesta en la actualidad sólo por fuste y cuerpo de campanas, se acometerán en una primera fase labores de consolidación estructural y de recuperación de sus revestimientos, estando prevista posteriormente la reposición del remate perdido a mediados del siglo pasado. Dicho (...) remate sería, según la memoria del proyecto de restauración, el originalmente proyectado para coronar la torre. Sin embargo, tanto el análisis del proceso constructivo del templo como el conocimiento de la arquitectura diocesana de la época, aspectos que desarrolla el presente artículo, así como algún testimonio gráfico coetáneo, llevan a datarlo indefectiblemente en una fecha muy posterior. El debate, pues, está servido. (shrink)

This paper argues that there is a thread in the philosophy of E. Tugendhat binding together his moral and justice theories with his conceptual analysis. Oriented by the thesis that a conceptual analysis is necessary to explain what justice is, this paper reconstructs some aspects of Tugendhat’s philosophy. It is divided in four sections: First, I delve into the author’s definition and use of conceptual analysis. Second, I describe some features of Tugendhat’s moral theory of contractualism. Third, I examine his (...) theory of justice. Fourth, I conclude by framing my analysis within the debate between Rawls’s and Tugendhat’s theories of justice. (shrink)
