Full textFor decades, France has imposed quotas for Francophone music. Radio stations need to reserve a minimum percentage of total song plays for French-language songs since 1996. The development of streaming services, which faces no quotas, has changed how we listen to music and poses a new challenge to regulators. The applicability of quotas is increasingly difficult in the radio broadcasting industry and raises the question of competitive disadvantage. In this thesis, I try to answer three main issues on the topic of music consumption in this changing ecosystem. First, I empirically examine the strategic responses of French radio stations to quotas for Francophone music. Do stations comply with the quotas? Is the realized audience for Francophone music lower than it would be in the absence of these strategic responses? To answer these questions, I use detailed data on the playlists of major radio stations in France to show that stations have some scope for adjusting their playlists subject to the quota constraints. Second, I build a dataset to provide some descriptive evidence on radio and streaming services. These are entirely different economic models, and are not comparable without adjusting the dataset to reflect the differences. In order to compare the audience number of music titles on radio stations with the number of streams on streaming services, I develop a methodology to combine radio data with streaming data in France in 2016. Third, using this novel dataset, I look at music consumption pattern and music variety on streaming services compares to that of radio. I also provide empirical evidence on the consumption externalities of both markets

Full textThe concept of ecosystem imported by Moore (1993) in strategy is increasingly used by practitioners and explored by researchers both theoretically and empirically. Conceived in this work as "a community of hierarchically independent, yet interdependent, heterogeneous participants who collectively generate an ecosystem outcome", the organizations involved face specific strategic issues, e.g. positioning in the structure, management of bottlenecks. During the renewal phase, organizations try, for example, to define the Value Proposition and to capture the value activated by the resulting innovation. Our literature review shows that the renewal phase is little investigated empirically and that, in general, the strategic issues are approached according to a functionalist approach or according to a voluntarist approach centered on a focal organization. In order to take relational dynamics into account, we ask the following question: “What are the individual processes and the collective organizational processes implemented during an attempt to renew an ecosystem? ". We answer this question with a single longitudinal case study with embedded units. We observe the failure of an attempted renewal project of an ESI. Data is collected continuously for more than three years using intervention and observation tactics. The analysis is carried out by means of a thematic coding based on an adaptation of the Gioia method. The results show that the organizations involved seek to limit changes in their own Business Models (BM hereafter) and, with regard to the need for BM matching, also seek to minimize changes in the partners' BM. The economic model thus proves to be structuring for the renewal of the ecosystem. The ecosystem we are studying is subject to a legal monopoly for the distribution network management activity. We observe that this situation gives significant power to the organization that benefits from it even though it does not own this network. We contribute to the literature on ecosystems by showing that the renewal of an ecosystem cannot take place in the absence of agreement on its new structure. We show the challenge for members to master the definition of PV and the governance of the ecosystem. We show the presence of a bottleneck creation strategy that does not only concern the technical aspects. We bring together the literature of ecosystems with that of BMs. The BM gives meaning to organizational and inter-organizational behaviors and specifies the parts of the environment with which an organization enters into a relationship. We observe that without pairing the BMs concerned, innovation cannot be introduced and the ecosystem cannot be renewed. We also conclude that the activity of Business Model Innovation (BMI hereafter) is a business activity. On the managerial level, we underline the necessary reassessment by the State of the legal structuring of an ecosystem with regard to new goals. We also provide managers with a tool and an approach to enable them to decide in an ecosystemic universe

Full textOver the past decade, new concepts have emerged in the electricity field, including the Smart Grids, the Distributed Generation and the Micro- grids (MGs). In this thesis, we will be mainly focusing on the study of the MGs. An MG is a small-scale power system, consisting of local power generation, local loads and energy storage systems. Thanks to their numerous economical, ecological and operational benefits, the MGs are expected to hold the promise of becoming a major ingredient in the implementation of the future power systems. However, there are several significant challenges to overcome in order to achieve its expected bene- fits, namely: the cyber-attacks, the mobility aspect, the interoperability, the non-cooperation, and the demand-side management. Three main contributions are developed. First, we present OntoMG, an ontology-based data model, capable of representing the heterogeneous components of the MG and their properties, while being compliant with existing models and information standards (i.e., IEC 61970 and IEC 61850) and coping with the interoperability issues and the multi-objective aspect of MG. Secondly, we introduce DECF, a cooperative model for the optimization of the electricity exchange in the MG, offering several advantages over existing approaches, in particular: 1) its generic in that it considers all heterogeneous components of MG, 2) it is a cooperative model that reduces the technical, ecological and economic costs and encourages the local power exchange, and 3) it is user-oriented in that it gives the user the possibility to fine-tune the weight of each objective aspect . Finally, we introduce MOCSF, a ‘Multi-objective Cooperative Scheduling Framework’ designed for scheduling the production, consumption and storage in the MG. MOCSF 1) provides a multi-type scheduling in that it allows the scheduling of all the power consumption, production and storage of the MG, 2) considers multiple energy sources and 3) considers the MG components’ preferences. After detailing the existing power scheduling techniques and their drawbacks regarding our challenges, we presented our ‘MOCSF’ modules: The Preference-based compromise builder, designed to generate the best balance between the sellers and buyers desired schedules and the Multi-Objective Scheduler, aiming at scheduling the seller-to-buyer associations resulting from the DECF, while reducing the operational, economic and ecological costs of the MG. An illustrative example is provided after each step to ease the understanding of each module. Finally, a set of experiments showed the performance and efficiency of our approach. Illustrative examples are provided after each step to facilitate understanding of each module. Then, a number of simulations are made to show the effectiveness of our approaches to solve our challenges in relation to the existing approaches

Full textAccording to the spatio-temporal constraints encountered, animals should adopt tactics enabling them to ensure their survival and reproduction. We sought to identify the tactics of resource use and time-budget as well as the factors causing their variation in two populations of large mammalian herbivores: the Mediterranean mouflon (Ovis gmelini musimon x Ovis sp. ) and the roe deer (Capreolus capreolus). We found that mouflon were particularly sensitive to strong summer heats and responded by decreasing their activity, in particular during the diurnal period. Concerning the habitat use, active mouflon used more the open habitats and less the deciduous forests than inactive mouflon. The location data used in this study came from GPS collars whose fix success is influenced by both animal behaviour and habitat characteristics (vegetation, topography). Lastly, we found that female roe deer adjusted the size of their home range according mainly to the abundance of resources, the number of fawns at heel, their age and the season. Based on these two case studies, our results highlight that large mammalian herbivores can adjust their activity and resource use according to their internal state and in response to changes of environmental conditions
