Blood supply chain design in disaster management: a comparison of risk-averse measures in robust optimization approaches
No full textDisasters, both natural and man-made, pose significant challenges to healthcare systems, particularly in managing blood supply chains effectively. Ensuring an adequate and timely supply of blood products becomes crucial during these crises to save lives and mitigate the impact of catastrophic events. This paper develops two-stage and multi-period risk aversion models for the blood supply chain in disaster management, focusing on mean-CVaR and worst-case criterion measures. We leverage advanced algorithms based on Benders decomposition and column-and-row generation techniques to produce practical solution methods which enable solving large-scale problem instances effectively. Numerical results demonstrate that thesemethods not only reduce the computational burden but also significantly enhance the solver’s ability to explorefeasible solutions efficiently.Our computational experiments show that a coarse approximation of uncertainty is more effective than a fine approximation and that good preparation enables a more effective response to an emergency. Our findings provide insights for policymakers, healthcare practitioners, and logistics professionals to improve blood supply chain management strategies in disaster response and preparedness efforts
The contribution of knowledge management to digital project integration: an empirical investigation
No full textInternational audienceThis article empirically investigates the role of knowledge management (KM) in digital project integration (DPI) using a conceptual model based on Supply Chain Integration theoretical framework and social exchange theory. DPI deals with the collaboration of digital project stakeholders (such as designers and product owners) to ensure that all aspects of their projects are aligned and working together successfully. 188 questionnaires were collected and analysed using partial least squares structural equation modelling (PLS-SEM). The results indicate that collaborative knowledge integration and socialisation mechanisms (as KM variables) positively impact partnership quality, which, in turn, influences DPI. In addition, results show that partnership quality fully mediates the relationships between collaborative knowledge integration, socialisation mechanisms, and DPI. Considering that previous studies on DPI have relied on qualitative approaches, this research extends the field by providing empirical quantitative validation of prior research findings. Practical recommendations are provided, emphasising trust and commitment as keys for successful KM and digital project outcomes
Business and Violent Conflict as a Multi-Dimensional Relationship: the case of post-Reformasi Indonesia
No full textInternational audienceThe private sector in general and multinational companies (MNCs) in particular have become an important part of the peace and conflict landscape. This article uses the Indonesian context to explore the foreign MNC-conflict relationship in the manufacturing sector and to add nuance to existing debates on the potential of MNCs in providing peacebuilding support through their investment or operational impacts, or their potential negative effects. We analyze the effects of various dimensions of corporate investment-based presence on violent conflicts, utilizing a cross-sectional model at the district level. We find that in industrial subsectors that are upward in the value chain, intensive in raw materials and low-skilled work (e.g., Heavy Industries, Food & Tobacco), foreign firm presence exacerbates local violent conflicts. Results in other sectors further down the value chain confirm the potentially positive role of MNCs in peacebuilding. These findings are also relevant for the wider CSR literature in that relationships between host countries and MNCs in fragile or conflict-affected areas are more complex than previously acknowledged, and call for additional research into sector-specific variances on business impacts in fragile and conflict-affected settings.The private sector in general and multinational companies (MNCs) in particular have become an important part of the peace and conflict landscape.

Sustainable human resource management: The good, the bad, and making it work
No full textInternational audienceOver the last five decades, the way we work has undergone a profound transformation. Full-time, and often life-long, employment within the same company has morphed into a very different reality. Workforce participation has expanded, the provision of flexible work schedules has become the new norm, work can seemingly be performed from anywhere, and there is a strong trend of individuals willingly switching jobs as they please. The rise of remote, part-time, and flexible work arrangements is a defining feature across myriad industries. While such changes have brought about advantages such as better pay, flexibility, autonomy, and physically safer working conditions for some, they have also negatively reshaped the employee-employer relationship for others. There has been a move away from the traditional standard employment relationship based on mutual loyalty, permanence, and job security to more flexible, temporary, and often precarious work arrangements. This shift has gained momentum due to changes in work and organizational design, technology and its mediation of communication, societal attitudes towards work-life balance, and the rise of digital platforms. A very clear example of this shift to hyper-flexibility can be seen in gig work, where workers engage with multiple ‘employers’ simultaneously through an online platform or ‘app’ based on algorithmic technology. This rapidly growing form of work has created new paths to employment but has also introduced uncertainties about its long-term viability and precariousness when compared to more traditional and stable forms of employment
Social collective organizing: a dynamic capability for the social resilience of a territory
No full textInternational audiencePurpose: This research explores how emergent social collectives contribute to the social resilience of their territory by enacting dynamic capabilities to face persistent social adversities untapped by local governments.Design/methodology/approach: We comparatively analyze two social collectives which emerged to tackle food poverty in Italy (Spesasospesa.org) and cardiac arrest in France (30 minutes to save lives). Through an abductive research approach, we search dynamic capabilities allowing social collectives and their founders to mobilize territorial capabilities and self-organize.Findings: The dynamic capabilities enabling social collective organizing for the social resilience of territories are : 1) interpreting an external trigger as an opportunity to address persistent social adversities (sensing); 2) mobilizing various territorial capabilities to ideate and implement a solution (seizing); 3) reconfiguring dynamic capabilities to further deploy and adapt the solution to new domains and geographical areas; 4) enacting overarching individual and organizational boundary spanning capabilities. Originality: This research outlines social resilience as a dynamic capability in social mission driven organizations rather than within firms, focuses on emergent and heterogeneous social groups and on long-term adversities affecting a territory. Its main contributions highlight: 1) how triggering events impact social collectives’ emergence and resilience capabilities mobilization ; 2) how social collective self-organizing and dynamic capabilities contribute to the social resilience of a territory; 3) how the pair of founders sense an opportunity and activate collective capabilities for social resilience; 4) the crucial role of boundary spanning capabilities; 5) how territorial characteristics influence the resilient capabilities mobilized
Perception de la RSE et choix de l’employeur : une étude sur des étudiants postbac en France
No full textInternational audienceResearch on behavior of younger generations, their characteristics and their relationship to work is quite numerous but little work has focused on post-baccalaureate Gen and the link between their CSR preference to apply for a new job. A quantitative study, with 136 students just before the Covid-19, highlights importance of commitment to CSR. Moderating effects of gender and training are significate. But there is no mediating effect of skepticism. Finally, these results are discussed as part of an approach relating to the prospective of commercial jobs and expectations of recruiters in terms of ethics and CSR.Les recherches sur le comportement des jeunes générations, leurs caractéristiques et leur rapport au travail sont assez nombreuses mais peu de travaux ont porté sur la génération postbac et le lien entre la responsabilité sociale des entreprises (RSE) et leur choix de postuler un emploi dans une entreprise. Une étude quantitative, menée auprès de 136 étudiants juste avant la crise de la Covid-19, permet de souligner l'importance de l'engagement en matière de RSE dans le processus de choix de leur futur employeur. Enfin, ces résultats sont discutés dans le cadre d'une démarche portant sur la prospective des métiers du commerce et les attentes des recruteurs en matière d'éthique et de RSE.n Mots-clés : étudiants postbac, scepticisme, RSE perçue, renoncement à postuler, choix de poste, prospective métiers.</p
The Impact of Fusion Metaphors in Health Appeals on Consumer Attitudes Tasty but Unhealthy, Healthy but Not Tasty: Duality Considerations in Health Messaging
No full textInternational audienceUsing structure-mapping theory, this research examines the efficacy of fusion metaphors in health campaigns aimed at changing consumer attitudes. Two experiments show that using fusion metaphors can have unintended consequences: Although these metaphors are meant to highlight the negative attributes of a target product, such as tasty but unhealthy food, they can inadvertently make the source product, such as a pack of cigarettes, appear more appealing. This poses challenges in effectively promoting health and may undermine the intended message of the campaign. This research brings both theoretical and managerial contributions by identifying the product attributes on which fusion metaphors are based
