Ben, Arbia Abir. "La conscience environnementale, sociale et économique comme vecteur motivationnel au comportement responsable des consommateurs collaboratifs et des simplistes volontaires". Electronic Thesis or Diss., Université de Lille (2022-....), 2023. http://www.theses.fr/2023ULILD020.
This thesis examines the role of environmental, social, and economic consciousness as a motivating factor in the adoption of responsible behaviors by collaborative consumers and voluntary simplifiers. The current postmodern context, characterized by a growing concern for social and environmental issues, presents a unique opportunity to study the transition towards socially responsible behaviors. This research contributes to understanding how consciousness of socially responsible consumption can motivate consumers to adopt responsible behaviors. These results provide valuable insights for various stakeholders advocating for sustainable and socially responsible consumption
El, Karmouni Hajar. "Le travail du consommateur pour la mise en place d'une alternative : cas du supermarché coopératif La Louve". Thesis, Paris Est, 2017. http://www.theses.fr/2017PESC0093/document.
Over the last decade, forms of voluntary consumer work have emerged in different areas (transport, accommodation, repair, etc.). They lead to a shift from a consumer "served" by the market to an "auto-produced" consumer.This Phd thesis is based on the study of a form of organization part of this movement, through the realization of a longitudinal study of the creation and launch of a cooperative and participatory supermarket, La Louve. This non-profit project proposes to offer quality food products at low cost. The work of its members is at the heart of the organizational and economic model of the cooperative, each consumer member having to provide 3 hours of work per month.Through this research, the acceptance of consumer participation in marketing, of working consumers (Dujarier, 2010), of voluntary work and of alternative are shaken. The thesis identifies a new form of work carried out by consumer-volunteers who self-assign the demands of professionals. It highlights the emergence of an organizational form supported by an alternative and responsible discourse, but whose management practices remain anchored in a pragmatic and non-militant approach. This collective of consumers reveals a utopian and pragmatist approach, the cooperators agreeing to provide free work by reproducing the salaried model of the companies and put into practice their skills to first meet their own needs.From this research, a new register of meaning emerges, that of a consumer working in a voluntary way characterized by his commitment without militancy and limited by a contract of voluntary work
Folz, Pauline. "Collaboration dans une fédération de consommateurs de données liées". Thesis, Nantes, 2017. http://www.theses.fr/2017NANT4052/document.
Following the Linked Data principles, data providers have published billions of RDF facts on the web. Anyone can retrieve some relevant information from the Linked Data by executing SPARQL queries. Such queries are useful in many domains including health or data journalism. However, there is a trade-off between performances of the queries and data availability when executing SPARQL queries. In this thesis, we have investigated how the collaboration of data consumers is opening new opportunities in this trade-off. More precisely, how the collaboration of data consumers can improve performances without degrading availability, or can improve availability without degrading performances. We consider that Linked Data can allow anyone to run a compact mediator that executes SPARQL queries over data sources on the web. The main idea is to connect these mediators together to build a federation of Linked Data consumers. In this federation, each mediator interacts with a subset of the network. Thanks to this federation, we have built : (i) a decentralized cache hosted by mediators. This client-side cache is able to handle a significative part of subqueries and then improve data availability without a low impact on performances. (ii) a delegation algorithm that allows mediators to delegate their queries to other mediators. We have demonstrated that delegation allows to run the workloads faster when collaborating. This clearly improves performances without degrading data availability
Malardé, Vincent. "Économie collaborative et régulation des plateformes numériques". Thesis, Rennes 1, 2019. http://www.theses.fr/2019REN1G006.
Facilitated by peer-to-peer platforms, the sharing economy has become part of the French way of life. Airbnb, Blablacar, Leboncoin... these platforms are now well known in France. This thesis aims to provide more elements, both theoretical and empirical, to inform the current debates around these platforms. This thesis work begins by using survey data to measure the importance of the use of collaborative platforms in France, and to establish the socio-economic characteristics of users. Then this thesis focuses on the dynamics of developing a collaborative platform,through the example of the French home-to-work ride-sharing platform, iDVROOM. The objective is to study the complementary role of network effects, spatial effects and community effects on the development of the platform. The rest of this thesis focuses on the competition between the short-term rental platform Airbnb and the hotel industry in Paris. The effect of the density of hosts on the collaborative platform on the price charged by an hotel is the subject of a firstempirical study, before being modeled in a theoretical way to discuss the possible effects of a set of alternative regulations of the platform’s activity. Finally, competition between two platforms is analysed when they have the possibility of implementing tariff discrimination strategies designed to encourage supplier exclusivity. The conclusion develops the implications of these results forpolicy makers, platforms and academic research
Bailly, Adrien. "De la consommation collaborative à l’économie de plateformes : étude des transactions entre particuliers dans l’espace socio-numérique". Thesis, Université de Lorraine, 2019. http://www.theses.fr/2019LORR0220.
The last decade has been marked by the emergence of numerous economic models associated with the notion of collaborative consumption. These consumption contexts need consumers to conduct new activities. This research aims to provide a theoretical understanding of these emerging practices. The notion of collaborative consumption itself is an important part of the phenomenon that we try to understand but doesn’t help us to circumscribe the object of this research. Indeed, the definitions proposed by researchers and by consumers do not allow to identify the specificity of collaborative practices. In this context, we choose to define the research object from a spatial point of view. The massive diffusion of digital technologies makes it possible to link spaces which were previously separate. It allows to carry out transactions that mix elements which traditionally belonged to the economic sphere or to the domestic sphere. This research is therefore limited to these transactions initiated online, i.e. those specific to a platform economy. A theory of science inspired by the pragmatist tradition and a mainly ethnographic methodological apparatus were used to study these transactions. Our study of the website www.leboncoin.fr allows us to identify how this platform fosters the acquisition of market skills without managing to solve the social exclusion inherent to this intermediation model. Our study of private renting initiated online allows us to explore the relationships between users and platforms induced by a more bureaucratic intermediation model. We also show the professionalization of practices. This work allows us to conclude that collaborative consumption is above all a set of narratives that accompany and legitimize platform capitalism and that intermediation relationships cannot be understood without taking into account the way in which consumers perform them and try to transform them
Sugier, Laure. "Le marketing face à ses résistances : une ethnographie des imaginaires et des pratiques de consommation des "objecteurs de croissance"". Rennes 1, 2012. http://www.theses.fr/2012REN1G018.
Ethical, responsible and sustainable consumption represent different forms of political consumerism, which aim at denouncing the consequences of the consumption society. Some individuals go beyond this consumerism, by resisting contemporary consumption society. This structural resistance is studied in this thesis using an ethnomarketing approach to study people who calls for economic degrowth and fight against three myths: the abundance myth, the market myth and the progress myth. These representations associated with the degrowth ideology have implications for production, exchange and consumption. Our observations draw attention to some interesting characteristics of this population in terms of avoidance of industrial production to the benefit of self-production, with a view to self-determination, the choice of a local territory and hybrid strategies combining the commercial and non-commercial spheres for exchanges as well as frugal and collective means of consumption. These characteristics are associated with those of the voluntary simplicity life style in a French context and are set in the perspective of symbolic dimensions of consumption
Manthé, Elodie. "Analyse du comportement d'investissement en equity crowdfunding : une approche par la valeur consommateur". Thesis, Bourgogne Franche-Comté, 2018. http://www.theses.fr/2018UBFCG003/document.
Equity crowdfunding is a recent investment mode, opening acces to venture capital to unsophisticated investors. ECF allows platform-based online investment within a virtual community.This research aims to improve understanding of indivual investors financial products consumption, in the ECF context, the so-called crowdinvestors.Building on consumption value theory, this research helps defining ECF-investment value sources for crowdinvestors. It focuses especially on the ‘participation in community’ dimension of ECF as a determinant of various investment behaviors.A litterature review in entrepreneurial finance is presented to define profiles, motivations, investment behaviors and quality signals influencing crowdinvestors’ investment decision.To answer three main research questions, an exploratory study was conducted on 13 members on french ECF platform WiSEED. We put in evidence the difference between the investment experience and the participation in community experienceThus, an empirical study based on a theoretical model is conducted and various PLS analysis are run on a set of 436 surveys answered by WiSEED members. Results show that perceived value of participation experience has a positive and significant influence on perceived value of investment but no influence at all on investment decision.Though, we highlight the central role of individuals’ venture capital expertise both on their investment (amount and number), their engagement within the platform community and their participation experience perceived value. inally, results indicate that perceived risk is not a moderator of the model whereas investor sophistication is
Beaudouin, Vanessa. "Le comportement du consommateur à l'égard des circuits courts alimentaires : une étude anthropologique du mouvement amapien". Thesis, Rennes 1, 2014. http://www.theses.fr/2014REN1G023.
In an economic context of globalization characterized by a succession of environmental, social and health crises, the recent development of alimentary short supply chains illustrates a major change in the perception of ethic and local consumption. Among these supply chains, the AMAPs, Associations for the Preservation of Local Farming, are grounded in local fair trade and constitute an increasingly privileged mode of supply. Based on ethnomarketing method, of long period immersion on the research field, this thesis aims to a thorough understanding of amapien's consumption. Emerging results lead us to first discuss the concept of proximity, through highlighting the link between proximity, trust and alimentary reassurance. Second, allow us to highlight a quest for the reenchantment of consumption, that requires the valorization of the act of simple buying and a quest for hedonism in the experience of consumption, the rooting of the individual through the quest of link and authenticity by consumption and finally a quest for spirituality. Finally, these results brought to light the empowerment of the amapien consumer, who takes power by participating to the shaping of market offer, and thanks to a socially responsible consumption, that may be connected, for some amapiens, to a resistance through and to consumption
Chamsi, Abu Quba Rana. "On enhancing recommender systems by utilizing general social networks combined with users goals and contextual awareness". Thesis, Lyon 1, 2015. http://www.theses.fr/2015LYO10061/document.
We are surrounded by decisions to take, what book to read next? What film to watch this night and in the week-end? As the number of items became tremendous the use of recommendation systems became essential in daily life. At the same time social network become indispensable in people’s daily lives; people from different countries and age groups use them on a daily basis. While people are spending time on social networks, they are leaving valuable information about them attracting researchers’ attention. Recommendation is one domain that has been affected by the social networks widespread; the result is the social recommenders’ studies. However, in the literature we’ve found that most of the social recommenders were evaluated over Epinions, flixter and other type of domains based recommender social networks, which are composed of (users, items, ratings and relations). The proposed solutions can’t be extended directly to General Purpose Social Networks (GPSN) like Facebook and Twitter which are open social networks where users can do a variety of useful actions that can be useful for recommendation, but as they can’t rate items, these information are not possible to be used in recommender systems! Moreover, evaluations are based on the known metrics like MAE, and RMSE. This can’t guarantee the satisfaction of users, neither the good quality of recommendation
Ben, Ticha Sonia. "Recommandation personnalisée hybride". Thesis, Université de Lorraine, 2015. http://www.theses.fr/2015LORR0168/document.
Face to the ongoing rapid expansion of the Internet, user requires help to access to items that may interest her or him. A personalized recommender system filters relevant items from huge catalogue to particular user by observing his or her behavior. The approach based on observing user behavior from his interactions with the website is called usage analysis. Collaborative Filtering and Content-Based filtering are the most widely used techniques in personalized recommender system. Collaborative filtering uses only data from usage analysis to build user profile, while content-based filtering relies in addition on semantic information of items. Hybrid approach is another important technique, which combines collaborative and content-based methods to provide recommendations. The aim of this thesis is to present a new hybridization approach that takes into account the semantic information of items to enhance collaborative recommendations. Several approaches have been proposed for learning a new user profile inferring preferences for semantic information describing items. For each proposed approach, we address the sparsity and the scalability problems. We prove also, empirically, an improvement in recommendations accuracy against collaborative filtering and content-based filtering

Dabadie, Isabelle. "Une approche socio-anthropologique de la consommation collaborative : focus sur les nouveaux rapports à la propriété". Thesis, Rennes 1, 2017. http://www.theses.fr/2017REN1G020.
Collaborative consumption refers to a highly varied range of practices – including rentals, loans, gifts, bartering and sharing between consumers – that challenge the primacy of individual ownership. This rapidly growing phenomenon has been the subject of many research studies that have attempted to define, map or explain it by identifying its determinants or evaluating its impact. Few researchers have focused on the cultural background to this movement. That is the focus of this study, which studies collaborative consumption from an anthropological perspective, looking at the central question of our relationship with ownership. This research, rooted in Consumer Culture Theory (CCT), adopts a phenomenological approach centred on the meaning of consumer experiences. In empirical terms, it uses an ethnographic study conducted in three different fields that reflect the diversity of collaborative practices: co-housing, collaborative pleasure boating and clothes libraries. Its main theoretical foundation is the use of an original analytical framework – cosmological infrastructure, inspired by the work of Stosczkowski (2008) – which highlights the salient traits of a particular worldview. The results reveal the emergence, within a movement that remains largely consumeristic, of a counterculture that is comparable to voluntary simplicity and characterised by a new relationship with ownership, which, for proponents of this counterculture, is not only replaced by the notion of usage but is also charged with different meaning. We call this the “cosmology of alter-possession”. This research provides a better understanding of the behaviour of consumers who maintain an ambivalent relationship with possessions, somewhere between detachment and the search for lasting links, and aspire to more open and collective forms of ownership in response to the social and environmental challenges in a world with finite resources
Privat, Hélène. "Étude des motivations au sélisme : dimensionnement, antécédents et influence sur la pratique séliste". Thesis, Brest, 2014. http://www.theses.fr/2014BRES0114/document.
According to the magazine Terra Eco (20 I 4), 48%o of French people are regular users of collaborative consumption, and 32%o of them are considering doing it. Despite the consumer craze for those alternative exchanges, comparatively, only a few marketing studies on the topic are currently made, This research's aim is therefore to analyse the various motivations of members from a physical network of collaborative consumption through the study of the local exchange trading system (LETS). The first chapter is focused on a state of play of the LETS, through its history, its geographical extent, its aims and uses. The second chapter will observe the LETS under an academic point of view. Through a litterature review, it will show how the differents disciplines are explaining this reality. It will also highlight in details what is determining LETS practices, and will end up suggesting an influence model on motivations behind becoming a LETS member, and their antecedents to the LETS practice. The third chapter will strenghten the model by a deep analysis of l6 semi-directives interviews of LETS users. The fourth chapter will put a light on the methodology used to test it. The fifth chapter will define a motivation scale on why becoming a LETS member, and to validate the measuring scales of the model. The sixth chapter will finally test the model and dig the results deeper. This quantitative study is based on a sample of 957 LETS users. Our thesis main assets are: a modelisation of the LETS member behavior, the discovery of two new motivations to join a LETS-distraction and intellectual enrichment, the creation of a motivation scale behind the decision of joining a LETS, analysis of their influences on the LETS practice, and the creation of a LETS member typology. To conclude, and based on those results, we'll come up with managing advices to give to LETS, to social or private workers from collaborative consumption networks, and also to the State and to territorial collectivities
Toussaint, Stéphanie. "Vers une compréhension de l'habiter dans la consommation : l'expérience des lieux de service polyfonctionnels". Thesis, Lille 2, 2016. http://www.theses.fr/2016LIL20008/document.
This thesis looks at the experience, by consumers, of multifunctionnal servicescapes. In a context of hypermodernity and collaborative consumption, we investigate the emergence of coworking spaces through an ethnographic approach and three case-studies. We look at how such places are produced and consumed, whereas offering hubs in which to work and live simultaneously. That is, this research highlights that coworking spaces can meld various functions of the space, from work-related experiences to cultural or ludic, single or communal, regular or occasional activities. Thanks to interviews and observational sessions, we show that flexibility and multifunctionnality of the space are key drivers of creativity. We also show that coworking spaces are built by users themselves through various mechanisms of temporary and collective appropriation, and through participatory management. Thus, the way people utilize coworking spaces suggests a new understanding of the serviscape experience as well as a new structural dimension of it: the lived-in experience (habiter)
Schwing, Maximilian. "Adoption Factors and Outcomes of Shared Micromobility Solutions – An Empirical Examination in Closed-Campus Environments". Electronic Thesis or Diss., Toulouse 1, 2023. http://www.theses.fr/2023TOU10002.
As an application of the sharing economy, shared micromobility refers to the shared use of light-weight transportation modes (e.g., e-scooter sharing). It is considered an integral part of sustainable urban mobility, as it reduces the reliance on individual motorized vehicles and solves the first-and-last-mile problem of public transportation. However, shared micromobility is controversial with consumer-related issues. Consequently, it has attracted interest outside and inside academia, and service providers innovate their solutions. In this context, this dissertation aims to understand how consumers adopt innovative shared micromobility by focusing on the application in closed-campus environments. First, we use the theory–context–characteristics–methodology systematic literature review protocol (Paul & Criado, 2020) to provide a holistic overview and research agenda of theoretical and empirical aspects at the intersection of marketing research on the sharing economy. Thus, we define our research questions related to 1) adoption factors and real user behavior 2) satisfaction and continuance intention to use 3) longitudinal effects of user experience on the perceptions of closed-campus micromobility. By setting up a field laboratory for shared micromobility in a closed-campus setting, we collect empirical survey and behavioral data to answer the related questions. Regarding the first question, we examine the antecedents of behavioral intention to adopt closed-campus micromobility and its influence on real user behavior. We draw on the UTAUT2 (Venkatesh et al., 2012) and integrate consumer perceived value theory (Holbrook, 1994), employee enablement theory (Adler & Borys, 1996) and privacy calculus theory (Martin & Murphy, 2017). The results indicate that performance expectancy, effort expectancy, task enablement, and hedonic and utilitarian value are significant antecedents of behavioral intention, which positively affects real use. Regarding the second question, we examine the antecedents of satisfaction and continuation behavior of closed campus micromobility. We draw on the expectation-confirmation model (Bhattacherjee, 2001) and integrate the theory of well-being (Diener et al., 1999) and consumer perceived value theory (Holbrook, 1994). The results reveal that subjective well-being is an antecedent of service satisfaction, which in turn is influenced by hedonic and economic values. Finally, regarding the third question, we examine the longitudinal effects of user experience. Based on UTAUT2 (Venkatesh et al., 2012) and regulatory focus theory (Avnet & Higgins, 2006), we add consumer perceived value theory (Holbrook, 1994), employee enablement theory (Adler & Borys, 1996), theory of well-being (Diener et al., 1999) and social identity theory (Ashforth & Mael, 1989). Through a within-subject design and two independent samples (short-term and long-term experience), we reveal that performance expectancy and task enablement are stable antecedents of usage intention, whereas hedonic value decreases. Concerning outcomes, we highlight the role of subjective well-being and organizational identification from the perspective of users and organizations. Our research offers contributions to the literature on technology adoption and shared micromobility, by highlighting important factors and outcomes that influence the decision to use shared micromobility solutions in closed-campus settings. We also offer methodological contributions. Thanks to the implementation of the field laboratory, we combine declarative survey data with real behavioral data and analyze longitudinal effects. To conclude, we present implications for both managers and policymakers who want to implement shared micromobility services
Gruen-Martin, Adèle. "Understanding consumer appropriation in access-based consumption as the creation of meanings : an investigation trough design". Thesis, Paris Sciences et Lettres (ComUE), 2017. http://www.theses.fr/2017PSLED016/document.
This dissertation aims to understand consumer appropriation of objects and places shared with others. We draw from theories of appropriation, access-based consumption and design to question the definition, the value and the emergence of consumer appropriation in access. We explore the contexts of car sharing and coworking spaces through four research articles. Our findings highlight the role of material objects in the enactment of consumer appropriation practices. We define consumer appropriation as the creation of meanings (sign value, linking value, wellbeing in use) enacted through a routinized set of practices between the consumer and the material elements of the access-based activity
