Carlo Sigonios De dialogo liber

Since Antiquity dialogue was one of the paradigmatic genres in theoretical discourse and its cognitive function was of fundamental significance in Renaissance theory of dialogue. This importance was considered for the first time by Carlo Sigonio in his De dialogo liber. Referring to Aristotle’s Topica, Sigonio defined dialogue as a written imitation of a dialectical disputation. He considered the arguments in a dialogue as well as in a dialectical disputation not to be based on scientific propositions, which are necessarily true, but to be based on commonly accepted premises. In consequence thereof, dialogue is not intended to generate indubitable knowledge but to foster „opinions“ (opinio), „beliefs“ and „convictions“ (fides), whose epistemological value is a matter of discussion. The intention of this paper is to present the arguments developed by Sigonio in order to explain that opinio and fides are not only legitimate epistemic goals, but sometimes the only reasonable ones. A further topic is the functions of dialectic and rhetoric within the framework of this cognitive concept

Experimental investigation of laminar turbulent intermittency in pipe flow

In shear flows turbulence first occurs in the form of localized structures (puffs/spots) surrounded by laminar fluid. We here investigate such spatially intermittent flows in a pipe experiment showing that turbulent puffs have a well defined interaction distance, which sets the minimum spacing of puffs as well as the maximum observable turbulent fraction. Two methodologies are employed here. Starting from a laminar flow puffs can be created by locally injecting a jet of fluid through the pipe wall. When the perturbation is applied periodically at low frequencies, as expected, a regular sequence of puffs is observed where the puff spacing is given by the ratio of the mean flow speed to the perturbation frequency. On the other hand, at large frequencies puffs are found to interact and annihilate each other. Varying the perturbation frequency an interaction distance can be determined. In the second set of experiments, the Reynolds number is reduced suddenly from fully developed turbulence to the intermittent regime.The resulting flow reorganizes itself to a sequence of constant size puffs which, unlike in Couette and Taylor Couette flow are randomly spaced. The minimum distance between the turbulent patches is identical to the puff interaction length. The puff interaction length is found to be in excellent agreement with the wavelength of regular stripe and spiral patterns in plane Couette and Taylor-Couette flow. We propose that the same interaction mechanism is present in these flows

Turismo gastronómico : dinamización del territorio y desarrollo local de la provincia de Castellón.

La gastronomía asociada al turismo puede ser valorada como uno de los productos inseparables que conforman el producto integral turístico, el que le aporta quizás mayor valor añadido, o valorada como parte del patrimonio cultural de una ciudad, región o país. En una u otra línea, su demanda está creciendo aceleradamente dando lugar a un nuevo segmento turístico.2 Algo más del 10% de los turistas que visitaron España en 2009, unos 5,5 millones, mencionaron la gastronomía como principal motivo para visitar el país, según datos facilitados por Turespaña en el I Congreso Europeo de Turismo y Gastronomía, celebrado en Madrid. 3 . Y otros productos más valorados y con distintivos de calidad como Denominación de Origen (DO), Identificación Geográfica Protegida (IGP) y Especialidad Tradicional Garantizada (ETG), por ello realizaremos una comparación del destino turístico gastronómico del País Vasco, y el desarrollo de su marca Eusko Label, en los productos agroalimentarios de calidad

Dialectical Topoi

a) Topics and Objectives: Dialectical topoi constitute an essential component of Aristotelian logic and theory of argumentation (dialectics). These can be characterized as essential patterns of argumentation which allow us to found premises which are suited to the establishment of specific theses. Our research group concentrates on two themes: the first working focus consists of a precise investigation of the topos-based dialectical logic found in Aristotle. We are concerned in particular with the dialectical texts contained in the Organon (Topics, Rhetoric, Sophistical Refutations), and we are considering their relationship to the formal logic developed in the Prior Analytics. The second focus of our work is an investigation of the reception of Aristotelian dialectics in the Renaissance. Occurring in the 16th century was in intensive reception of the Aristotelian Topics, as suggested by numerous new translations and commentaries. We are concentrating on the relationship between veritas/scientia and opinio/probabilitas in the epistemology of the Renaissance. In particular, we are interested in the question of how the dialectics and rhetoric of the Renaissance were influenced by the form and genre of the dialogue, and in the role played in the Renaissance by the spatial dimension, which is contained both in Aristotle’s definition of the topos as the »place from which the attack comes«, as well as in Cicero’s definition of the locus as the »seat of the argument« (sedes argumentorum). b) Methods: Relevant passages from the texts of the Aristotelian Organon are analyzed and set into relationship with one another. Consulted in particular in interpreting these texts is the inventory of 20th century theories dealing with logic and argumentation; modern mereological and topological systems, for example, are used in reconstructing Aristotelian logic, albeit without overlooking the historical specificity of the problems that are bound up with these antique texts. c) State of the Discussion: The group has concluded that Aristotelian formal logic is dependent upon and was shaped in various ways by topos-based dialectical logic. Aristotelian predication theory, for example, plays a decisive role for various aspects of the Aristotelian syllogistic which is contained in the Prior Analytics. Beyond this, the group has demonstrated that interpretations of the Aristotelian Topics made an essential contribution to the emergence of a relativistic epistemology in the Renaissance. The status of opinio/probabilitas in the Renaissance, for example, was influenced by interpretations of the Aristotelian concept of endoxon
