Thinking collaborative empowerment as a communication dispositive : the case of collaborative consumption’s online community services in a sustainabl…

2020

This thesis propounds an info-communicational approach of empowerment phenomenon in a market oriented context. In order to do so, we focus on discourses and communicational processes that refer to this very concept in “collaborative consumption” platforms’ framework. Massification of this type of services is accompanied by discourses emphasizing a socioecological “power” they would be carrying for consumers (as a more social and sustainable economy). We underline the gap between this utopia and the organizational reality of empowerment. First part of this thesis proposes to highlight this polysemic concept. The point is to problematize empowerment in tension between political communication …

Info-communicationnal approach of medical cannabis self-medication : analysis of figures mobilized in knowledge legitimation within a community dedic…

2022

This thesis proposes an infocommunicational approach to self-medication with medical cannabis. We question the logic of knowledge legitimization in a context where the coercive power of the French state is exercised. We seek to understand how the use of cannabis is determined in a radically constrained legislative framework, for users in a recreational or self-medication approach, but also for doctors and patients in a medical approach. To do this, we analyze the processes of knowledge legitimization that allow the development of practical know-how allowing individuals to consume cannabis in a self-medication approach within clandestine health communities of practice, supported by participa…

Découverte et analyse des communautés implicites par une approche sémantique en ligne : l'outil WebTribe

2012

With the rise of Web 2.0 and collaborative technologies that are attached to,the Web has now become a broad platform of exchanges between users. The majorityof websites is now dedicated to social interactions of their users, or offerstools to develop these interactions. Our work focuses on the understanding of theseexchanges, as well as emerging community structures arising, through a semanticapproach. To meet the needs of web analysts, we analyze these community structuresto identify their essential characteristics as their thematic centers and centralcontributors. Our semantic analysis is mainly based on reference light ontologiesto define several new metrics such as the temporal semantic…

Link between microbial diversity, stability of microbial communities and soil organic matter turnover

2014

Soil microbial communities act as important agents of the biological soil functioning, particularly through their involvements in the transformations of biogeochemical cycles (C, N, P…). In agro-ecosystems, the diversity of these communities is affected by perturbations associated to agricultural practices, and the significance of these modifications in terms of preservation of biological functioning and sustainability of agricultural systems has emerged as a central issue in the environmental sciences. Whereas the role of biodiversity has been well studied for macroorganisms, in particular for plants; the biodiversity/activity relationship is still largely unknown for soil microorganisms. …

 Engagement éco-citoyen et participation en ligne : entre agir communicationnel et agir stratégique

2012

International audience; Dans le cadre d’une recherche-action retenue au sein du programme MOVIDA (développé par le Ministère de l’Environnement, du Développement Durable, du Transport et de la Logistique), nous envisageons sur un plan fonctionnel les leviers et les freins communicationnels à une consommation éco-responsable à l’échelle d’un quartier de la ville de Dijon, en France. Mais la participation des habitants à ces dispositifs est loin d’être acquise. La théorie de la communication engageante propose une méthodologie qui permettrait de motiver et mobiliser ces habitants efficacement autour de l’éco-citoyenneté. Nous proposons dans cet article de revenir sur la problématique de la pa…

Relation entre transitivité et structure de communauté dans les réseaux complexes

2011

The relation between community structure and other topological properties in complex networks, has not been analyzed clearly. In this preliminary study, we explore experimentally the potential link between transitivity and community structure. We study the evolution of transitivity based on the quality of the community structure on artificially generated networks. Then we observe the evolution of community structure according to transitivity value. The results show a relationship between high transitivity and community structure. Additional analytical work is needed to identify the exact nature of this relationship.

Origins of the blemishes of potato tubers : from the soil microbiology to the pedoclimatic environment

2010

The visual quality of fresh potatoes, Solanum tuberosum, became a dominant criterion and a significative economical issue in potato market. According the vegetative reproduction of this species, requirements for visual quality are also needed for potato seed tubers. As an organ for reserve and propagation, the tuber grows underground and is in contact with soil-borne microorganisms, making it potentially exposed to blemishes, for the majority of which the origin is still unclear. The objective of this work is to make an inventory of those tuber blemishes, to characterize them and determine their causes. After the establishment of consensual nomenclature and classification of the blemishes, …

Approche géographique des approvissionnements en plaquettes foréstières des chaufferies du secteur collectif/tertiaire : application au Pays Loue-Lis…

2011

In a context of strong increase of fuelwood demand in the collective sector, the supply issue becomes central to all stakeholders, raising many issues relating to land and forestry planning, local development, environment ... Meanwhile, questions emerge: how much energy can be mobilized sustainably? Does the spatial and structural configuration of forests influence the supply process? Do we seek to minimize transport distances? Can we observe spatial competition between the boilers ? To understand the current organization of supplies, we analyzed two sets of data traceability of wood chips. Then, we have developed a model of local supply basins, considering constraints of renewability of th…

Le marketing tribal électronique: vers une rationalisation sociale généralisée de la socialisation en ligne ?

2010

International audience; L’instrumentalisation marchande du phénomène de socialisation électronique, sans nous questionner plus avant ici sur son efficacité économique réelle, réactualise la question de la rationalisation du lien social à l’heure de la massification d’Internet. Cette rationalisation est considérée par beaucoup de penseurs critiques, à la suite des travaux d’Habermas sur l’Espace Public, comme un affaiblissement, voire une disparition d’un être-ensemble détaché pour partie de la raison calculatoire, de la logique de l’intérêt. Ainsi, les stratégies marketing ciblant la population internaute, que l’on pourrait rassembler en nous inspirant de Bernard Cova et de Michel Maffesoli…
