On the volumetric response of a compacted clay subjected to wetting and drying cycles
2009
Experimental evidence on the volumetric response of a compacted clay was collected in controlled suction oedometric tests, with the aim to assess the volumetric response of this soil when subjected to wetting and drying cycles. The overall soil behaviour seems mainly to depend on the double structural arrangement observed in the compacted specimens. Selected results are presented and discussed focusing on the influence of the stress history on the volumetric response. Test results are simulated by a double-structure suction-dependent elasto-plastic constitutive model, in which the mechanical response is related to micro and macrostructural deformations and their mutual interactions. The pro…
El control de la comprensión de textos científicos en inglés como lengua extranjera, en estudiantes universitarios españoles no bilingües : evaluació…
2013
'Esta tesis presenta un estudio sobre el uso de estrategias metacognitivas y su impacto en la comprensión lectora en inglés como LE de estudiantes universitarios españoles. Se analiza dónde se encuentran las deficiencias, en su caso, y cómo pueden ser superadas mediante intervenciones didácticas apropiadas. Los estudios empíricos realizados se agrupan en tres grandes bloques. El primer bloque está dedicado a la caracterización de los estudiantes universitarios en lo que respecta a su competencia lectora en inglés. Un primer estudio evalúa el dominio lingüístico en inglés y las principales dificultades que presentan estos estudiantes para poder comunicar y comprender ideas básicas en esta le…
Longitudinal analysis of Spanish doctoral theses in education (1841-2012)
2014
This article analyzes the research output of doctoral theses in the field of Education defended in Spain from 1841-2012. It offers a quantified global and diachronic view of such series. As a landmark to note is the fact that until 1954, obtaining a doctoral degree was centralized at the Complutense University of Madrid. They are used as search engines bibliographic databases: TESEO and institutional repositories, and basic bibliography of the area to carry out the collection of the sample. The contrasting hypothesis is to verify whether the time series partially follows the pattern of growth of the science of Derek J. de Solla Price. The central finding is that the Spanish production of do…
Les actes capitulars de la Seu de Xàtiva (segle XVIII). Estudi i edició
2015
Les actes capitulars de la Seu de Xàtiva (segle XVIII). Estudi i edició, constitueix un estudi sobre la importància del llenguatge administratiu eclesiàstic dintre de l’edat moderna, un període que havia estat tradicionalment menystingut sobretot a partir de denominacions que no eren massa propícies. És de tots sabut el tractament negatiu que ha rebut la llengua catalana i la seua literatura produïda entre els segles XVI i XVIII —tant des del punt de vista dels escrits més creatius com des dels altres camps: escriptura privada, textos administratius, judicials, processals, legislatius, eclesiàstics... No fa encara massa, hom sempre emprava el terme «Decadència» per a caracteritzar aquest pe…

Towards a General Definition of Modeling
2010
What is a model? Surprisingly, in philosophical texts, this question is asked (sometimes), but almost never – answered. Instead of a general answer, usually, some classification of models is considered. The broadest possible definition of modeling could sound as follows: a model is anything that is (or could be) used, for some purpose, in place of something else. If the purpose is “answering questions”, then one has a cognitive model. Could such a broad definition be useful? Isn't it empty? Can one derive useful consequences from it? I'm trying to show that there is a lot of them.
Comportements migratoires des étudiants et des jeunes diplômés.
2008
Until now, analyses about migrations of young people linked with French higher education seemed to focus only on costs and advantages. Especially students in training and young graduates integrating labour market. They consider strategies of job searching and studies efficiencies. Until now, these analyses about French students' and graduates' migrations didn't take into account geographical dimensions. From now, national databases allow studying regional migrations of both students and graduates. Now, one can answer to questions like: do they migrate the same way? Do regions influence the way they migrate? Main results are explained in three developments. The first one presents main charac…
Interactions, spillovers de connaissance et croissance des économies modernes. Faut-il préférer la globalisation ou la proximité géographique ?
2009
Globalisation and metropolisation in modern economies induce some locational strategies of knowledge based activities towards cities and deeply increase trade and move of ideas across cities. In that context, we study the way knowledge spillovers have influenced the economic growth of 82 European Metropolises over the 1990-2005 period. We model knowledge spillovers across cities according to three specific interaction patterns depending either on geography or on global advanced services or thought a combination of these patterns. We show that the mixed pattern matters the best for economic growth of cities in Europe.
Recursion at the crossroads of sequence modeling, random trees, stochastic algorithms and martingales
2013
This monograph synthesizes several studies spanning from dynamical systems in the statistical analysis of sequences, to analysis of algorithms in random trees and discrete stochastic processes. These works find applications in various fields ranging from biological sequences to linear regression models, branching processes, through functional statistics and estimates of risk indicators for insurances. All the established results use, in one way or another, the recursive property of the structure under study, by highlighting invariants such as martingales, which are at the heart of this monograph, as tools as well as objects of study.
