Predictive Vision of Physics of Decision : Modelisation of Virus Propagation with Force Fields Paradigm
No full textInternational audienceThis paper introduces a novel method for simulating complex system behaviors using a specific geometric space and force fields within that space. The approach considers the system's performance as a physical trajectory defined by its performance indicators and environmental attributes, which can be deviated by force fields representing risks or opportunities within the system. The primary contribution of this work is the proposal of a method that uses multiple trajectories of a defined system to identify force fields that accurately represent the system
Emergence of Fintech in the Financial Landscape: Stakes of Fintech and Competition with Traditional Banks
No full textInternational audienceThe purpose of this paper is to empirically study the stakes of Fintech and competition with traditional banks. Through interviews with 18 specialists working in various fintechs, the empirical results show that most of the fintechs elaborate on their in-house technology available via an online customizable platform, while other functionalities considered as out of the core Fintech activities are developed via external outsourcing. Fintechs face significant systemic challenges, including an evolving regulatory framework that can constrain ambitions and the need for rigorous compliance processes. Protecting personal data against hackers is also vital for these start-ups. The paper further shows that banks are not fundamentally threatened by fintech, given their essential role in the economy, especially credit intermediation. The relationship between the two appears more cooperative than competitive, with growing momentum for banks to acquire fintechs to accelerate digitalization and foster innovation. The scientific novelty lies in framing dual tech as a common operating pattern and showing that banks and fintechs are complementary through partnerships and acquisitions.</div

The past, present and future of research on emotions in cross-cultural management
No full textInternational audienceThis paper presents a bibliometric and textual analysis of academic literature on emotions within the context of cross-cultural management. A bibliometric analysis uses co-citation and bibliographic coupling to reveal trends in the field, both past and present. Additionally, the Reinert lexicometric method is used to explore promising research directions as outlined in recent articles. The key findings suggest that the foundations of emotions in cross-cultural management lie in cultural and emotional intelligence, in the use of cultural dimensions as a framework for studying emotions, and in both international and psychological adaptation. These themes persist in current research with slight variations. Future research is expected to focus on empirical studies, developing theories of emotional intelligence, and contextual studies of acculturation, among other areas. Based on an integrative framework of emotions in cross-cultural management, we propose a research agenda and implications for practice
Application of the coupled Eulerian-Lagrangian method to the roller compaction modelling
No full textInternational audienceThe roller compaction (RC) process of powders is a steady-state operation characterized by large deformationsand complex contact interactions. Traditionally, it is modelled using the Arbitrary Lagrangian–Eulerian (ALE)method, which requires frequent remeshing of the Lagrangian domain to preserve solution accuracy. To over-come this limitation, this study explores the Coupled Eulerian–Lagrangian (CEL) method, which can accom-modate large deformations without mesh distortion.The CEL approach is implemented in Abaqus/Explicit, with an imposed inlet feed velocity and zero outletpressure as Eulerian boundary conditions. A steady-state solution is achieved through a general transient (non-steady-state) simulation. To improve computational efficiency of the explicit analysis, the simulation time isartificially reduced by increasing the material density.The results highlight the strong potential of the CEL method to accurately predict the key characteristics of theroll compaction process, showing good agreement with both experimental measurements and ALE-based sim-ulations reported in the literature. The study also shows that while mesh size significantly affects interface ac-curacy, it does not influence the stable time increment. Overall, the CEL approach offers a promising alternativefor simulating roller compaction without mesh distortion and provides deeper insight into roller-powderinteractions
Multi-stakeholder Insights on Integrating Public Transport for Urban Freight Deliveries
No full textInternational audienceThis paper explores the integration of public transport networks for urban freight deliveries within the framework of Hyperconnected City Logistics (HCL), focusing on multi-stakeholder perspectives. By synergizing freight and passenger networks, the study optimizes parcel consolidation and containerization in the urban middle-mile, efficiently moving parcels between access hubs during off-peak hours to reduce reliance on dedicated freight vehicles. The model is validated through computational experiments based on public transport system, evaluating various collaboration strategies among multiple logistics service providers. Specifically, it examines three consolidation policies: independent, where each provider reserves its own vehicle; partially shared, where different providers share the same vehicle, but containers remain separate; and fully integrated, where parcels from different providers are consolidated in the same container. To compare policies, a realistic case study based on the city of Bordeaux, provides insights into the operational and collaborative potential of integrating public transport into urban logistics
