The role of Private Equity-firms in the formation of strategic alliances
2014
This research analyses the role of Private Equity firms in the formation of strategic alliances within the field of the French Private Equity market. We start to provide evidence of its importance from new survey information, before offering an explanation of the organizational phenomenon. The study addresses the questions of how and why Private Equity firms act as relational intermediaries to help their portfolio companies form alliances. Both questions are investigated in the light of the Private Equity firms’ contribution to the value creation process that comes with alliance formation. Answers are provided by means of three jointly used theoretical frameworks: (1) mainstream theories (t…

Bridging landscape graphs and genetic graphs for analysing habitat ecological connectivity
2021
Several key ecological processes for maintaining biodiversity rely upon the ecological connectivity of habitat. Accordingly, connectivity modelling methods have been developed for understanding precisely the influence of connectivity and deriving sound biodiversity conservation measures. Among them, landscape graphs represent habitat networks as sets of habitat patches (nodes) connected by potential dispersal paths (links). Yet, the ecological relevance of these tools required validation from biological data reflecting closely the influence of habitat connectivity. Genetic data allow for such validation as population genetic structure partly depends on dispersal-driven gene flow between hab…
Influencer e diversità della pelle
2021
Ce travail s’appuie sur une série d’entretiens semi-directifs conduits avec des patientsatteints de nævus géant congénital (une maladie dermatologique rare) et les associationsimpliquées dans leur accompagnement psycho-social. Les résultats mettent en exerguel’importance des rencontres face-à-face et de l’appartenance à un groupe de pairs dans leprocessus d’acceptation et de normalisation de la différence corporelle. L’étude montre enoutre une segmentation des pratiques et des logiques de représentation de la rareté dansles différentes arènes. L’espace associatif, en ligne et hors ligne, transpose la logique de lacoopération et le renforcement de l’expertise des usagers du système sanitaire…
Integrated modelling of the influence of urbanization and climate change on river water quality
2010
Climate change is one of the most important drivers modifying the hydrologic and environmental characteristics of natural catchments. When dealing with the quality of natural waters, these factors should be weighed up against anthropogenic factors that may increase or decrease the effect of climatic modifications. However, a detailed and more generalised analysis of such environmental impacts at a relatively small scale is currently lack. This paper aims to fill this gap. The use of a holistic approach is also required by the EU Water Framework Directive, which prescribes integrated analysis for river basin management in order to meet environmental and ecological objectives. In order to qua…
L'émergence de la notion de "pôle d'échanges" : entre interconnexion des réseaux et structuration des territoires
2008
This article explores the concept of " interchange station ", through an analysis terminology. The evolution of semantic networks nodes that we detail in this work, shows a more off their dual dimension to both network element and territory. Based on a literature review, this terminology will help clarify neighbours words used in different contexts. The article demonstrate that the emergence of the term " interchange station " and its equivalent " park and ride" makes sense in relation to the evolution of these devices. Indeed, the need to "appoint" those places complex demonstrates their importance in the organization of networks and urban functions (distribution of the habitat, activity, …

Entangled states and coherent interaction in resonant media
2014
The entanglement features of some solid state materials, as well as of particular systems of interacting atoms and fields are analyzed. A detailed investigation of the rich phase structure of low dimensional spin models, describing the natural mineral azurite and copper based coordination compounds, has revealed regimes with the most robust entanglement behavior. Using the dynamical system approach, the phase structure of some classical models on hierarchical (recursive) lattices has been also studied and, for the first time, the transition between chaotic and periodic regimes by means of tangent bifurcation has been detected.A detailed description of entanglement properties of three atoms …
