Factors Affecting the Consumers’ Purchase Intention and Willingness-to-Pay More for Electric-Vehicle Technology
2021
This study conducted an in-depth analysis of the factors affecting consumers’ intention to purchase and willingness to pay more for an electric vehicle (EV) in the developing-country context, extending the theory of planned behavior with two new variables: environmental concern and willingness to pay (WTP) a premium. Survey data were collected from 358 responses and were analyzed using partial least squares structural equation modeling. Multi-group analysis was conducted, and the moderating role of gender was examined. The findings showed the significant effects of the theory-of-planned-behavior variables and environmental concern on EV technology purchase intention. The present study provi…
The participant interview: a method to understand the individual's experience in the car
2019
L’individu dans son automobile, durant ses déplacements quotidiens, habite d’une façon ou d’une autre l’espace circonscrit dans lequel il se trouve alors. De ce point de vue, il apparaît nécessaire de développer une ethno-sociologie des manières d’habiter son automobile. Pour atteindre cette ambition heuristique, nous préciserons ici les termes de cette méthode que nous nommons « entretien participant ». Hybridant les méthodes de l’entretien et de l’observation participante, l’entretien du rapport de l’individu contemporain à son automobile alternant sans cesse entre réflexivité et routines, entre repli sur soi et disponibilité au monde et à soi.
Operator Revenue Analysis for Device-to-Device Communications Overlaying Cellular Network
2018
Device-to-device (D2D) communications has recently gathered significant research interest due to its efficient utilization of already depleting wireless spectrum. In this article, we considered a scenario where D2D users communicate in the presence of cellular users in an overlay network setup. In order to analyze the revenue of service providers in monetary terms, the paper provides exact expressions of operator profit for both D2D and cellular users. More specifically, we take into account different network parameters including user density, transmit power and channel variations to understand their impact on the total revenue of the operator. Finally, we derive the balancing value of freq…
Motifs de démotorisation des actifs et retraités dans les aires urbaines françaises : premiers résultats statistiques de l'enquête MoDe
2021
Based on a nationwide quantitative survey conducted on 2,000 households (including 1,000 demotorised households and 1,000 non-demotorised twin households), we propose to provide an overview of demotorisation in France. This survey by questionnaire was conducted during the winter of 2017-2018 with a panel of households representative of the French population (from the Metaskope panel of Kantar-TNS ex-TNS-Sofres). Combined with the ?Parc Auto? panel survey (Kantar-TNS for Ademe-CCFA-Ifsttar-DSR), this survey is an original source of data on the French demotorised households. From two multinomial logit regression models, for both active and retired populations, this data allows to highlight th…
Energy Efficient Optimization for Wireless Virtualized Small Cell Networks With Large-Scale Multiple Antenna
2017
Wireless network virtualization is envisioned as a promising framework to provide efficient and customized services for next-generation wireless networks. In wireless virtualized networks (WVNs), limited radio resources are shared among different services providers for providing services to different users with heterogeneous demands. In this paper, we propose a resource allocation scheme for an orthogonal frequency division multiplexing-based WVN, where one small cell base station equipped with a large number of antennas serves the users with different service requirements. In particular, with the objective to obtain the energy efficiency in the uplink, a joint power, subcarrier, and antenn…
Underwater Multirobot Cooperative Intervention MAC Protocol
2020
This work introduces a Medium Access Control (MAC) protocol designed to allow a group of underwater robots that share a wireless communication channel to effectively communicate with each other. The goal of the Underwater Multirobot Cooperative Intervention MAC (UMCI-MAC) protocol presented in this work is to minimize the end to end delay and the jitter. The access to the medium in UMCI-MAC follows a Time Division Multiple Access (TDMA) strategy which is arbitrated by a master, which also has the capability to prioritize the transmission of some nodes over the rest of the network. Two experiments have been carried out with a team of four Autonomous Underwater Vehicles (AUV) in order to comp…
Youngtimers. Une sociologie des rapports contemporains à la voiture ancienne
2023
Le présent texte est tiré de la soutenance de la thèse de doctorat en sociologie intitulée « Youngtimers. Une sociologie des rapports contemporains à la voiture ancienne » et soutenue le 21 novembre 2022 à Dijon devant un jury composé de : Hervé Marchal (professeur de sociologie à l’université de Bourgogne, co-directeur de thèse), Vincent Kaufmann (professeur de sociologie à l’EPFL, co-directeur de thèse), Jean-Marc Stébé (professeur de sociologie à l’université de Lorraine, rapporteur), Ewa Bogalska-martin (professeure de sociologie à l’université Grenoble Alpes, rapporteure), Cornelia Hummel (professeure de sociologie à l’université de Genève et présidente du jury) et Jean-Christophe Marc…
