The 'power' of tourism in Portugal

2012

The author analyses the upper tail of the distribution of tourism supply in Portugal from 2002 to 2009, using data from the Instituto Nacional de Estatística database. Tourism supply is defined in terms of the lodging capacity of hotel establishments in about 250 tourist destinations. The paper shows that the empirical distribution of tourism supply in Portugal is heavy-tailed and consistent with a power law behaviour in its upper tail. Such behaviour seems to be stable over the years, provided that, for the time horizon covered by the data sets, the scaling parameter is always close to the value of two. The power law hypothesis is tested positively through the use of graphical and analyti…

On local optima in minimum time control of the restricted three-body problem

2016

International audience; The structure of local minima for time minimization in the controlled three-body problem is studied. Several homotopies are systematically used to unfold the structure of these local minimizers, and the resulting singularity of the path associated with the value function is analyzed numerically.

Comment les parents déterminent les tailles de portions destinées à leur enfant ? Approche sociologique

2021

Introduction et but de l'étude: Il est établi que des tailles de portions majorées peuvent inciter les enfants à consommer au-delà de leurs sensations de faim, altérer leurs capacités d'autorégulation de la prise alimentaire et in fine induire un surpoids. Aussi les enfants sont-ils dépendants de l'offre alimentaire proposée par leur parent. Pour autant, peu d'études se sont intéressées à la façon dont les parents déterminent la taille des portions servies à leur enfant. Matériel et méthodes: Au moyen d'entretiens semi-directifs réalisés auprès de 5 pères et 32 mères d'enfants de 3 à 5 ans, nous avons cherché à décrire les pratiques parentales de détermination de la taille des portions serv…

Diversity and complexity of microbial communities from a chlor-alkali tailings dump

2015

Abstract Revegetation of the tailings dumps produced by various industrial activities is necessary to prevent dust storms and erosion and represents a great challenge for ecological restoration. Little is known about the microbial colonisation and community structure of revegetated tailings following site exploitation. Here, we report the sequencing of 16S rRNA and internal transcribed spacer (ITS) fungal RNA gene amplicons from chlor-alkali residue and from an adjacent undisturbed soil to define the composition and assembly of the rhizosphere microbial communities. After quality filtering, a total of 72,373 and 89,929 bacterial sequences and 122,618 and 111,209 fungal sequences remained fo…

Entanglements, transmission processes and social identities. The technical traditions of ceramics in the Three-Lakes region and its margins (3600-300…

2019

In Western Europe, the second half of the 4th millennium is a turning point. On the Swiss Plateau, this phase is characterized by the end of Middle Neolithic cultures (Cortaillod and Pfyn) around 3550 BCE, and the emergence of Horgen after 3250 BCE. The transition between these two phases is now better documented thanks to Port-Conty type and Pfyn/Horgen settlements dated around 3400 BCE. This work aims to identify the cultural substract at the origin of the Horgen by characterizing the technical identities and entanglements at the end of the 4th millennium, then by identifying over time the transmission or abandonment of certain ways of making pots in order to determine the share of local …

Contacts culturels au 36e-35e siècles av. J.-C. : les traditions techniques de la céramique de Geispolsheim "Forlen" (Bas-Rhin)

2023

L’étude d’une série de vases du Néolithique récent sur le site de Geispolsheim « Forlen » a permis de définir le Munzingen C, l’étape finale de cette culture en Basse-Alsace (3650-3400 av. J.-C.). Cette définition repose avant tout sur une approche typologique qui a permis de mettre en évidence les fortes affinités existant avec la culture de Pfyn. Cette contribution se propose de compléter cette approche par une analyse technologique qui, bien que confirmant l’originalité de cette production et ses liens avec le Pfyn, permet aussi de mettre en lumière ses relations avec les productions tardives duCortaillod.
