Combining a data-driven approach with seasonal forecasts data to predicting reservoir water volume in the Mediterranean area.
2021
<p>Artificial reservoirs are one of the main water supply resources in the Mediterranean areas; their management can be strongly affected by the problems of drought and water scarcity. The reservoir water level is the result of the hydrological processes occurring in the upstream catchment, which, in turn, depend on meteorological variables, such as rainfall and temperature. It follows that a reliable forecast model of the meteorological forcing, along with a reliable water balance model, could enhance the correct management of a reservoir. With regard to the rainfall/temperature forecast model, the use of forecast climate data in the mid-term may provide further support for t…
Modifications in Water Resources Availability Under Climate Changes: A Case Study in a Sicilian Basin
2014
Climate variability due to the greenhouse effect has important implications on hydrological processes and water resources systems. Indeed, water availability, quality and streamflow are very sensitive to changes in temperature and precipitation regimes whose effects have to be fully considered in current water management and planning. International literature proposes several models, attempting to assess accurately the available water resources under stationary and changing climatic conditions at different spatial and temporal scales. In order to assess the potential impacts of climate change on surface and groundwater resources water availability in a Southern area of Italy, a conceptual h…
Des Vertus et du roi : relectures d'une iconographie du gouvernement : France-Italie, XIIIe-XVIIe siècles
2019
My doctoral work in the history of medieval art unfolds from a multistep process. Based on the initial finding pertaining to the pervasive use of an iconography of Virtues in the Middle Ages, something specific emerged: its presence in sites of government, as well as its common association with the powerful, be it in the civic or religious spheres. The powerful encompasses here individuals representing various types of government existing during the medieval era in the western world. These are kings, princes, members of royal families, religious and lay dignitaries, as well as tyrants and, on the other end of the spectrum, representatives of local governments. All these characters are surro…
Les privatisations de l'éducation
2019
International audience; Les processus de privatisation « en » éducation et « de » l'éducation concernent désormais la plupart des pays du monde. Dans un contexte de mondialisation et d'internationalisation accrues des systèmes éducatifs, la mise en oeuvre, ces dernières décennies, de mesures spécifiques de privatisation, le développement d'un secteur marchand de l'éducation, mais aussi des évolutions sociétales de fond concernant les notions d'individualisme et d'individu interrogent d'une nouvelle manière les enjeux liés aux privatisations.La promotion des intérêts privés est-elle compatible avec un processus d'éducation ? Induit-elle irrémédiablement, par exemple, une conception utilitari…
Transmission Heterogeneity and Control Strategies for Infectious Disease Emergence
2007
Background The control of emergence and spread of infectious diseases depends critically on the details of the genetic makeup of pathogens and hosts, their immunological, behavioral and ecological traits, and the pattern of temporal and spatial contacts among the age/stage-classes of susceptible and infectious host individuals. Methods and Findings We show that failing to acknowledge the existence of heterogeneities in the transmission rate among age/stage-classes can make traditional eradication and control strategies ineffective, and in some cases, policies aimed at controlling pathogen emergence can even increase disease incidence in the host. When control strategies target for reduction…
Les savoirs enseignants en EPS : mode d'accès et intégration à la formation
2017
International audience; Le dossier thématique a trait à la problématique des savoirs des enseignants, laquelle sera abordée sous l'angle des recherches francophones, notamment celles issues des développements actuels en didactique. Nous voulons partager et mettre au jour les connaissances sur cette problématique dans le domaine de l'Éducation physique et sportive (ÉPS), et ce, autant en ce qui concerne les modes d'accès, par la recherche, que les modes de formation aux savoirs et d'appropriation des savoirs par les enseignants et par les élèves. Soulignons, toutefois, qu'elle n'est pas exclusive à l'éducation physique et qu'elle s'inscrit dans un champ de recherches beaucoup plus large et p…
Soft Nanoonions: A Dynamic Overview onto Catanionic Vesicles Temperature-Driven Transition.
2020
Catanionic vesicles are emerging interesting structures for bioapplications. They self-generate by a pairing of oppositely charged ionic surfactants that assemble into hollow structures. Specifically, the anionic-cationic surfactant pair assumes a double-tailed zwitterionic behavior. In this work, the multilamellar-to-unilamellar thermal transition of several mixed aqueous systems, with a slight excess of the anionic one, were investigated. Interestingly, it was found that the anionic counterion underwent a dissociation as a consequence of a temperature increase, leading to the mentioned thermal transition. The present work proposed the spectroscopic techniques, specifically multinuclear NM…
L'incertitude en médecine générale : sources, formes et accommodements possibles
2008
Cet article analyse la maniere dont l’incertitude se presente en medecine generale, a partir d’une enquete sociologique qualitative conduite sur plusieurs annees aupres de medecins generalistes francais. Les sources et formes de l’incertitude medicale y sont d’abord envisagees a la lumiere des categories classiques de Fox et des caracteristiques du contexte historique, economique et social d’exercice de la medecine generale en France. On examine ensuite la facon dont les generalistes s’accommodent de l’incertitude et stabilisent plus ou moins une attitude par rapport a cette donnee importante de leur pratique. Le propos aboutit a une cartographie des positionnements des generalistes qui ren…
Medium enthalpy geothermal systems in carbonate reservoirs, the Western Sicily example.
2013
The multidisciplinary and integrated review of existing data (mainly acquired during oil exploration), specifically reread for geothermal purposes, and the integration with new data acquired in particular key areas, such as the Mazara Del Vallo site in the southern part of western Sicily, allowed us to better understand this -regional scale- medium-enthalpy geothermal system (with measured temperatures up to 100 °C), to reconstruct the modalities and peculiarities of fluids circulation, and to evaluate the geothermal potentialities of western Sicily. We suggest that these findings could be taken as exemplificative of the behavior of low-to medium enthalpy geothermal systems hosted in carbon…
The paradoxical management of service skills
2015
This paper focuses on service skills which are mobilized by front office agents when they are involved with customers. These skills are most of the time tacit. We consider that the way in which firms recognize these skills and contribute to their development is an important management issue. It is all the more important that a lot of jobs combine poor levels of qualification and highly situated skills.
