Análisis de la evolución de la línea de costa entre Alcossebre y Orpesa a partir de fotografía aérea (1956-2015)
2019
[ES] El artículo presenta un análisis de la evolución de la línea de costa entre Alcossebre y Orpesa, a partir de fotografías aéreas y ortofotografías, entre 1956 y 2015. La digitialización de 12 líneas de costa ha permitido calcular los cambios netos y máximos, así como la tasa de cambio entre los diferentes años. Los resultados muestran una costa recesiva, con una gran variabilidad espacio-temporal. Conviven sectores con crecimiento sostenido provocado por la acción antrópica (deriva arriba de los espigones y regeneraciones de playa) o causas naturales (prominencias costeras), con otros claramente erosivos (deriva abajo de espigones). Además, el análisis de las isobatas del estrán sumergi…
Phytoplankton dynamics in permanent and temporary Mediterranean waters: is the game hard to play because of hydrological disturbance?
2012
Only few scientific investigations have been carried out, to our knowledge, on phytoplankton in Mediterranean temporary ponds. To test the hypothesis that climate forcing is the main factor affecting dynamics and structure of planktic algae in these peculiar ecosystems, and to assess the importance of human impacts on this basic component of the aquatic biota, phytoplankton structure and dynamics were analysed in two temporary, long lasting (9 months), ponds, and in a permanent one. The three studied water bodies can be classified as mesoeutrophic, which show extended macrophyte beds and are subjected to one or more human impacts, such as eutrophication, fish and plant introduction, and gar…
Semantic and action tool knowledge in the brain: Identifying common and distinct networks.
2021
Most cognitive models of apraxia assume that impaired tool use results from a deficit occurring at the conceptual level, which contains dedicated information about tool use, namely, semantic and action tool knowledge. Semantic tool knowledge contains information about the prototypical use of familiar tools, such as function (e.g., a hammer and a mallet share the same purpose) and associative relations (e.g., a hammer goes with a nail). Action tool knowledge contains information about how to manipulate tools, such as hand posture and kinematics. The present review aimed to better understand the neural correlates of action and semantic tool knowledge, by focusing on activation, stimulation an…
Collezione
2022
The house represents not only the place of living, but also of exhibiting: we can consider it both a Thoreau-style refuge and a private London memory club, a world within a world. There are heterogeneous objects considered of value (sacred, secular, personal, collective) so much as to be transformed into a "collection". It is exhibited with the function of representation so that the personality and interests of the inhabitant are observed by visiting third parties, or to be enjoyed in the form of a private autobiography in a personal theater of memory between Giulio Camillo and Abi Warburg.
The Mona Lisa effect: Neural correlates of centered and off-centered gaze
2014
The Mona Lisa effect describes the phenomenon when the eyes of a portrait appear to look at the observer regardless of the observer's position. Recently, the metaphor of a cone of gaze has been proposed to describe the range of gaze directions within which a person feels looked at. The width of the gaze cone is about five degrees of visual angle to either side of a given gaze direction. We used functional magnetic resonance imaging to investigate how the brain regions involved in gaze direction discrimination would differ between centered and decentered presentation positions of a portrait exhibiting eye contact. Subjects observed a given portrait's eyes. By presenting portraits with varyin…
Qualité et efficience de l'école primaire française : éléments de comparaisons spatiales et temporelles
2008
08001 - 20 p.; Document de travail de l'IREDU 2008-01; L'objectif principal de ce texte est de présenter des éléments factuels sur les résultats de l'école primaire française. Notre réflexion portera sur deux dimensions complémentaires, à savoir la qualité et l'efficience, celles-ci seront examinées dans une double perspective comparative (temporelle et spatiale). Dans une première partie, nous mobiliserons les données des enquêtes internationales pour apprécier les résultats des élèves français et leur évolution dans le temps sur ces 15 dernières années. La seconde partie sera consacrée aux coûts de l'enseignement primaire et plusieurs aspects seront abordés. Dans un premier temps, l'évolu…

Evaluation of Structural and Temporal Properties of Ego Networks for Data Availability in DOSNs
2017
The large diffusion of Online Social Networks (OSNs) has influenced the way people interact with each other. OSNs present several drawbacks, one of the most important is the problem of privacy disclosures. Distributed Online Social Networks (DOSNs) have been proposed as a valid alternative solution to solve this problem. DOSNs are Online Social Networks implemented on a distributed platform, such as a P2P system or a mobile network. However, the decentralization of the control presents several challenges, one of the main ones is guaranteeing data availability without relying on a central server. To this aim, users’ data allocation strategies have to be defined and this requires the knowledg…
Towards Diagrammatic Patterns
2008
This article presents the idea that the graphical representation (concrete syntax) of a visual language can be specified based on some pre-defined diagrammatic patterns. A diagram from the Specification and Description Language (SDL) is used as illustration.
