Principaux facteurs du bien-être dans le domaine du tourisme : Une application au cas du tourisme sportif actif
2021
The quest for well-being is one of the driving forces behind human behaviour, this quest being particularly observed in tourism, which is considered to be an activity that provides it. However, the causes of well-being are not yet fully understood. The aim of this article is to identify the main factors likely to contribute to the well-being experienced in a tourist environment by using the fields of positive psychology and consumer behaviour and, beyond, marketing. Firstly, the contributions of positive psychology to the analysis of well-being will be presented. Secondly, an integrating model of the well-being factors in tourism will be suggested. This model will bring together the analysi…
G-Spaces and Kaluza-Klein Theory
1988
G-spaces are present whenever symmetries are relevant in physics. After a short introduction to this subject, spontaneous symmetry breaking in elementary particle physics is considered from this point of view. Kaluza-Klein theory is discussed in a purely geometrical formulation. Some results in connection with the geometrical compactification scheme are presented.
The Influence of Strategic and Organizational Factors as Concern the Relationship between Environmental Management Control and Organizational Learnin…
2020
This article examines the relationship between Environmental Management Control (EMC) and Organizational Learning (OL) by extending the theoretical model of Simons (1995) in a contingent perspective. Through strategic and organizational factors, this enriched model expounds the links between the Simons’s (1995) levers of control (diagnostic and interactive controls) and the Argyris and Schön’s (1978) levels of learning (simple loop learning and double loop learning). Based on the “revelatory case” of a missionary organization, eco-SME, this study highlights the influence of three contingency factors : strong core values, proactive strategy and activity life cycle in the four configurations …
Le verbe faire en français contemporain entre factitif et suppléant
2016
International audience; L’omniprésence du verbe faire dans la communication n’est ni une réalité récente, comme en témoigne, entre autres, l’excellent ouvrage de T. Ponchon pour le français médiéval (1994), ni la propriété privée de la langue française, comme l’attestent les analyses ressortissant à la linguistique comparée. Pour les besoins de cette communication, il conviendra d’examiner les propriétés dudit mot dès lors qu’il Oscille entre ses velléités de factitif et celles de suppléant. Les exemples suivants représentent assez fidèlement cette dualité : – « Elle s’est fait faire les seins. » – « Ah, bon ? Pourtant, ils font vrais. » – « Non, non. Je te laisse regarder. Tu verras qu’ils…
GESTION DES RISQUES ET DES INCERTITUDES L'EMERGENCE D'UN CONTRÔLE DE GESTION " PAR EXCEPTION "
2003
International audience; Le thème de la gestion des risques a été peu abordé en contrôle de gestion et le fonctionnement des outils traditionnels comme les budgets postulent une maîtrise des risques et des incertitudes. L'émergence de nouvelles approches en contrôle de gestion montre une évolution sur ce point.
Effect of Oral Physiology Parameters on In-Mouth Aroma Compound Release Using Lipoprotein Matrices: An In Vitro Approach
2019
Temporal aroma compound release during eating is a function of the physicochemical properties of the food matrix, aroma compounds, and oral physiology of individuals. However, the influence of each parameter on the release of each aroma component should be clarified. Two flavored lipoprotein matrices varying in composition were chewed in a chewing simulator that reproduced most of the physiological functions of the mouth. Aroma compound releases (butanoic acid, 2-heptanone, ethyl butyrate, 3-octanone, and 2-nonanone) were followed in real time by direct connection of the device to APCI-MS (atmospheric pressure chemical ionization mass spectrometry). Each oral parameter was controlled and de…
Relationship between the comma theory and Witten’s string field theory
1998
The comma representation of interacting string field theory is further elucidated. The proof that Witten's vertex solves the comma overlap equations is established. In this representation, the associativity of the star algebra is seen to hold. The relationship of the symmetry K in the standard formulation of Witten's string field theory to that in the comma theory is discussed.

The geometry of N=3 AdS4 in massive IIA
2018
The geometry of the ${\cal N} = 3$, SO(4)--invariant, AdS$_4$ solution of massive type IIA supergravity that uplifts from the ${\cal N} = 3 $ vacuum of $D=4$ ${\cal N} = 8$ dyonic ISO(7) supergravity is investigated. Firstly, a $D=4$, SO(4)--invariant restricted duality hierarchy is constructed and used to uplift the entire, dynamical SO(4)--invariant sector to massive type IIA. The resulting consistent uplift formulae are used to obtain a new local expression for the ${\cal N} = 3 $ AdS$_4$ solution in massive IIA and analyse its geometry. Locally, the internal $S^6$ geometry corresponds to a warped fibration of $S^2$ and a hemisphere of $S^4$. This can be regarded as a warped generalisati…
On the Super Higgs Effect in Extended Supergravity
2002
We consider the reduction of supersymmetry in N-extended four dimensional supergravity via the super Higgs mechanism in theories without cosmological constant. We provide an analysis largely based on the properties of long and short multiplets of Poincare' supersymmetry. Examples of the super Higgs phenomenon are realized in spontaneously broken N=8 supergravity through the Scherk-Schwarz mechanism and in superstring compactification in presence of brane fluxes. In many models the massive vectors count the difference in number of the translation isometries of the scalar sigma-model geometries in the broken and unbroken phase.
