Los conectores pragmáticos en español coloquial (I) : su papel argumentativo
1993
Entre los elementos que favorecen la cohesión y la coherencia de la conversación coloquial desta can los llamados conectares pragmáticos, unidades que, además de encadenar las unidades del hebla, aseguran la transición de determinadas secuencias del texto hablado, colaborando en el mantenimiento del hilo del discurso y la tensión comunicativa. El conector pragmático se presenta como articulador frástico y transfrástico al mismo tiempo. Y en este sentido su papel se vincula predominantemente a la organización de la actividad discursiva como marcador metadiscursivo o la actividad argumentativa como conector argumentativo. En concreto, en su función argumentativa, tiene la propiedad funcional …
L'attaccamento ai luoghi come modello interpretativo delle relazioni dell'uomo con la cultura. Una ricerca su un campione di ragazzi tunisini della c…
2014
L'attaccamento al luogo è un essenziale bisogno umano in grado di nutrire il senso dell'identità di individui e collettività, a prescindere dai cambiamenti della società. Intento principale in questo lavoro di tesi è quello dell'integrazione, legato al fenomeno dell' intercultura. Il lavoro di tesi è riferito nello specifico nella città di Mazara del Vallo, centro nevralgico di incontro di culture. Ho scelto di indagare la percezione del luogo da parte della popolazione immigrata, coinvolgendo in particolare gli adolescenti che costituiscono la cosiddetta "seconda generazione", e confrontandone le opinioni con quelle espresse dai coetanei autoctoni. L'aspetto più propriamente statistico rig…
Two-species model for spatial distributions of sardine and anchovy: A comparison with real data
2010
We present a study of pattern formation in a set of two coupled equations modeling two competing species. We consider generalized Lotka-Volterra equations in the presence of a multiplicative noise which models the interaction between the species and the environment. The interaction parameter between the species is a random process which obeys a stochastic differential equation with a generalized bistable potential in the presence of a periodic driving term, which accounts for the environment temperature variation.We find noise-induced spatial patterns with strong anti-correlation between the two species. We compare our theoretical results with the experimental data of the spatial distributi…

A statistical monitoring approach for automotive on-board diagnostic systems
2007
The current generation of vehicle models are increasingly being equipped with on-board diagnostic (OBD) systems aimed at assessing the ‘state of health’ of important anti-pollution subsystems and components. In order to promptly diagnose and fix quality and reliability problems that may potentially affect such complex diagnostic systems, even during advanced development prior to mass production, some vehicle prototypes undergo a testing phase under realistic conditions of use (a mileage accumulation campaign). The aim of this work is to set up a statistical tool for improving the reliability of the OBD system by monitoring its operation during the mileage accumulation campaign of a new vehi…
Definición de las necesidades sociales para un nuevo desarrollo del sistema de Servicios Sociales de la Comunidad Valenciana, desde una metodología p…
2017
La falta de información sobre el Sistema de Servicios Sociales Valenciano es conocida por todas/os las personas que tienen relación con él, tanto desde la praxis profesional como docente. La finalidad de esta investigación era comenzar a recoger información sobre el sistema, que tuviera utilidad tanto académica como profesional. La crisis está haciendo desaparecer el sistema, pero al no existir datos previos, no se puede indicar con certeza qué estaba sucediendo, y por qué. Estas explicaciones e informaciones se debían obtener de quién las vive de primera mano; las y los profesionales. Se planteó la investigación con una metodología de IAP (investigación-acción participativa), pues se consi…

Spectroscopic parameters related to non bridging oxygen hole centers in amorphous-SiO2
2005
The relationship between the luminescence at 1.9 eV and the absorption bands at 2.0 eV and at 4.8 eV were investigated in a wide variety of synthetic silica samples exposed to different gamma- and beta-ray irradiation doses. We found that the intensities of these optical bands are linearly correlated in agreement with the model in which they are assigned to a single defect. This finding allows to determine spectroscopic parameters related to optical transitions efficiency: the oscillator strength of the 4.8 eV results ~200 times higher than that of the 2.0 eV; the 1.9 eV luminescence quantum yield under 4.8 eV excitation is lower (by a factor ~3) than that under 2.0 eV excitation. These res…
Radiation Response of Ce-Doped Phosphosilicate Optical Fibers
2014
International audience; We report an experimental study of the radiation effects on silica-based multimode optical fibers (OFs) either doped with Phosphorus or with Phosphorus and Cerium. Online Radiation-Induced-Absorption (RIA) measurements were performed in the UV-visible spectral domain under 10 keV X-ray Irradiation. Optical Absorption (OA) in the Near Infrared Region (NIR) and Electron Paramagnetic Resonance (EPR) measurements were also performed on γ-irradiated OFs.
