La música práctica en san Agustín: "vestigium" y "signum"

En distintos momentos de su producción intelectual, Agustín se refirió al asunto de la música. En este artículo mostraremos que Agustín uso dos esquemas conceptuales distintos para describir el fenómeno de la música práctica en su relación con el mundo espiritual, el esquema de las Artes Liberales y el de la teoría del signo, y que en virtud de ello la música sería concebida de dos modos diferentes: como vestigium y como signum del mundo espiritual, respectivamente. Al final del artículo analizaremos la diferencia entre las dos concepciones considerando tres elementos: la naturaleza de la relación entre mundo material y espiritual, el contenido espiritual al que remite y la noción de belleza que implica.

El "Fedro" de Platón: un ejercicio de buena retórica engañosa

En este artículo me propongo mostrar que lo que Sócrates hace con Fedro a lo largo de toda la obra no es otra cosa que utilizar la auténtica retórica (con su doble carga, dialéctica y psicológica) que es descrita en la segunda parte del diálogo. Las tensiones, rivalidades y celos de la situación inicial entre ellos expone un perfil representativo de relaciones entre interlocutores con perspectivas intelectuales opuestas. Es preciso disolver la resistencia emocional por medio de una serie de pasos graduales, estratégicos, y ‘engañosos’ (no se puede develar el propio juego desde el principio). Hay que partir de acuerdos, siquiera parciales, para continuar dialogando. Sin embargo, Sócrates también introduce nociones nuevas acerca del amor, pero éstas pasan desapercibidas a un Fedro obsesionado con la imitación de su enamorado Lisias. Hasta que Sócrates decide cortar el juego y cruzar el río. Este corte provoca un giro en ambos personajes: Fedro se dispone a escuchar lo que Sócrates quiere contarle (el mito del carro alado) y Sócrates se revela ante sí mismo como un personaje capaz de ‘encantar’ a Fedro con la belleza rapsódica del relato y superar su propio temor de convertirse en una bestia devoradora. Al final Sócrates muestra su juego a Fedro y le enseña cómo ha sido posible llegar a un auténtico diálogo filosófico, donde pueda tener lugar la enseñanza y el aprendizaje recíprocos.

La crítica de Plotino a la concepción aristotélica del tiempo en "En". III 7

El presente trabajo intenta mostrar de qué manera Plotino refuta la noción aristotélica del tiempo como «número» o «medida del movimiento», cuáles son las aporías que plantea, cómo las compulsa con sus propios argumentos y qué soluciones propone con respecto a esa misma confrontación. Todo esto será encauzado a partir de un estudio descriptivo y analítico, acompañado de una lectura a la vez hermenéutica y crítica de los textos seleccionados para esta ocasión.

The use of cues for attention in ancient Greek art: aspects that influence concentration in the work of art and its elements

The goal of this study is to identify cues for the cognitive process of attention in ancient Greek art, aiming to find confirmation of its possible use by ancient Greek audiences and artists. Evidence of cues that trigger attention’s psychological dispositions was searched through content analysis of image reproductions of ancient Greek sculpture and fine vase painting from the archaic to the Hellenistic period - ca. 7th -1st cent. BC. Through this analysis, it was possible to observe the presence of cues that trigger orientation to the work of art (i.e. amplification, contrast, emotional salience, simplification, symmetry), of a cue that triggers a disseminate attention to the parts of the work (i.e. distribution of elements) and of cues that activate selective attention to specific elements in the work of art (i.e. contrast of elements, salient color, central positioning of elements, composition regarding the flow of elements and significant objects). Results support the universality of those dispositions, probably connected with basic competencies that are hard-wired in the nervous system and in the cognitive processes.

Committing to Economic Openness in Ireland: The Importance of Domestic Institutional Capabilities

This chapter sets out to explain the factors behind Ireland's exceptional period of economic growth from the early 1990s to the mid 2000s. It suggests that an unbending commitment to economic openness and an on-going effort to establish quality domestic institutions were the main drivers of the so-called ‘Celtic tiger’ phenomenon. The commitment to economic openness manifested itself in the relentless search for inward investment and a willingness to accept deep forms of European integration. Building domestic institutional capabilities involved adopting new-classical macroeconomic policies, creating a robust system of social partnership and reforming the educational system. The two factors positively interacted with each other to create dynamic effects.

A Tree Augmented Classifier Based on Extreme Imprecise Dirichlet Model

In this paper we present TANC, i.e., a tree-augmented naive credal classifier based on imprecise probabilities; it models prior near-ignorance via the Extreme Imprecise Dirichlet Model (EDM) (Cano et al., 2007) and deals conservatively with missing data in the training set, without assuming them to be missing-at-random. The EDM is an approximation of the global Imprecise Dirichlet Model (IDM), which considerably simplifies the computation of upper and lower probabilities; yet, having been only recently introduced, the quality of the provided approximation needs still to be verified. As first contribution, we extensively compare the output of the naive credal classifier (one of the few cases in which the global IDM can be exactly implemented) when learned with the EDM and the global IDM; the output of the classifier appears to be identical in the vast majority of cases, thus supporting the adoption of the EDM in real classification problems. Then, by experiments we show that TANC is more reliable than the precise TAN (learned with uniform prior), and also that it provides better performance compared to a previous (Zaffalon, 2003) TAN model based on imprecise probabilities. TANC treats missing data by considering all possible completions of the training set, but avoiding an exponential increase of the computational times; eventually, we present some preliminary results with missing data.

Os castrati e a prática vocal no espaço luso-brasileiro (1752-1822)

A presente tese tem como objeto de estudo os castrati em Portugal e no Brasil, visando principalmente às atividades musicais realizadas nos teatros da corte portuguesa entre 1752 e 1822. A partir de documentação histórica inédita, como livros de despesa do governo, os relatos fornecidos por viajantes estrangeiros da época, libretos, partituras originais e correspôndencias, a tese aborda o percurso histórico dos castrati italianos ampliando o entendimento sobre as práticas musicais que esses cantores protagonizaram tanto em Lisboa como no Rio de Janeiro.

The book under review is the publication of 28 contributions to a workshop which has tak en place in St. Augustin, near Bonn, in November 1995. This was attended by a large number of proeminent scholars, gathered around the commonly felt concern for the need to preserve “the oral traditions of all kinds” (p. 26). The papers, written in German (11), in English (16) and in French (1), are introduced by the organisers Walter Hessig and Rüdiger Schott in both German and English.

TEC4SEA - A Modular Platform for Research, Test and Validation of Technologies Supporting a Sustainable Blue Economy

This paper presents the TEC4SEA research infrastructure created in Portugal to support research, development, and validation of marine technologies. It is a multidisciplinary open platform, capable of supporting research, development, and test of marine robotics, telecommunications, and sensing technologies for monitoring and operating in the ocean environment. Due to the installed research facilities and its privileged geographic location, it allows fast access to deep sea, and can support multidisciplinary research, enabling full validation and evaluation of technological solutions designed for the ocean environment. It is a vertically integrated infrastructure, in the sense that it possesses a set of skills and resources which range from pure conceptual research to field deployment missions, with strong industrial and logistic capacities in the middle tier of prototype production. TEC4SEA is open to the entire scientific and enterprise community, with a free access policy for researchers affiliated with the research units that ensure its maintenance and sustainability. The paper describes the infrastructure in detail, and discusses associated research programs, providing a strategic vision for deep sea research initiatives, within the context of both the Portuguese National Ocean Strategy and European Strategy frameworks.

TURTLE: Systems and technologies for deep ocean long term presence

This paper describes the TURTLE project that aim to develop sub-systems with the capability of deep-sea long-term presence. Our motivation is to produce new robotic ascend and descend energy efficient technologies to be incorporated in robotic vehicles used by civil and military stakeholders for underwater operations. TURTLE contribute to the sustainable presence and operations in the sea bottom. Long term presence on sea bottom, increased awareness and operation capabilities in underwater sea and in particular on benthic deeps can only be achieved through the use of advanced technologies, leading to automation of operation, reducing operational costs and increasing efficiency of human activity.
