The continent-to-ocean transfer of rare earth elements in a mediterranean setting: natural processes and anthropogenic emissions
No full textInternational audienceDespite the ecological and geochemical importance of coastal and estuarine ecosystems, the continental inputs and anthropogenic emissions of trace elements in their global marine budgets are not well constrained due to a lack of comprehensive and inclusive assessment of diverse sources. Here, we investigated two small but representative rivers (Las and Eygoutier) of the Mediterranean Sea to determine the contributions of rare earth elements (REEs) from terrestrial loadings, atmospheric depositions, and anthropogenic emissions within the watersheds and Toulon Bay (France). Both the dissolved and particulate loadings of the rivers significantly increased during intermittent flood conditions relative to base flow. The flow-weighted mean concentrations of dissolved Nd (as a representative REE) ranged from 29 ± 6 and 41 ± 16 ng L -1 for the two rivers repectively, while the time-weighted mean particulate concentrations (TWMC) were 8.0 ± 3.4 and 18.8 ± 6.3 mg kg -1 . Similarly, TWMCs of atmospheric depositions were 13.3 ± 1.8 and 23.7 ± 4.0 mg kg -1 for dry and wet conditions. Atmospheric depositions and fluvial particulate loadings are the primary input and output within the watershed, while river dissolved fluxes, porewater diffusion, and atmospheric depositions are the primary external sources of Nd to the water column. Furthermore, we observed significant La anomalies in the dissolved and atmospheric fractions while the discharge of treated wastewater is a significant REE input to the bay, marked by Tb anomalies. Overall, these results suggest considering small but typical rivers, rather than focusing solely on major fluvial systems, to gain a more comprehensive understanding of the transport and fate of REEs at the continent-to-ocean interface.</div
Enabling Explainable Artificial Intelligence capabilities in Supply Chain Decision Support Making
No full textInternational audienceExplainable artificial intelligence (XAI) has been instrumental in enabling the process of making informed decisions. The emergence of various supply chain (SC) platforms in modern times has altered the nature of SC interactions, resulting in a notable degree of uncertainty. This study aims to conduct a thorough analysis of the existing literature on decision support systems (DSSs) and their incorporation of XAI functionalities within the domain of SC. Our analysis has revealed the influence of XAI on the decision-making process in the field of SC. This study utilizes the SHapley Additive exPlanations (SHAP) technique to analysis the online data using Python machine learning (ML) process. Explanatory algorithms are specifically crafted to augment the lucidity of ML models by furnishing rationales for the prognostications they produce. The present study aims to establish measurable standards for identifying the constituents of XAI and DSSs that augment decision-making in the context of SC. This study assessed prior research with regards to their ability to make predictions, utilization of online dataset, number of variables examined, development of learning capability, and validation within the context of decision-making, emphasizes the research domains that necessitate additional exploration concerning intelligent decision-making under conditions of uncertainty

Learn2Reg 2024: New Benchmark Datasets Driving Progress on New Challenges
No full textInternational audienceMedical image registration is critical for clinical applications, and fair benchmarking of different methods is essential for monitoring ongoing progress in the field. To date, the Learn2Reg 2020-2023 challenges have released several complementary datasets and established metrics for evaluations. Building on this foundation, the 2024 edition expands the challenge’s scope to cover a wider range of registration scenarios, particularly in terms of modality diversity and task complexity, by introducing three new tasks, including large-scale multi-modal registration and unsupervised inter-subject brain registration, as well as the first microscopy-focused benchmark within Learn2Reg. The new datasets also inspired new method developments, including invertibility constraints, pyramid features, keypoints alignment and instance optimisation
In Search of Entrepreneurial Masculinities: Exploring Accomplishments, Social Constructions, Ideals, and Hegemonies
No full textInternational audienceThis SI builds on an expanding literature looking at entrepreneurial masculinities (see Smith, 2010; Hechavarria and Ingram, 2016; Giazitzoglu and Down, 2017; Jernberg et al., 2020; Smith, 2021; Smith, 2022; Balkmar et al., 2024; Hytti et al., 2024; Forster-Holt and Davis, 2025). This literature shows the heterogeneity that defines entrepreneurial masculinities. There are multiple configurations of masculinities that are expressed by..
Engagement with Social Media Sexual Health Communities: Motivations and Outcomes of Consumers with Different Sexual Preferences
No full textInternational audienceAs concerns about sexually transmitted diseases rise, individuals increasingly rely on social media–based communities for peer-driven information and support due to persistent barriers to appropriate medical care. Using a qualitative, multi-method approach that combines in-depth interviews with netnographic observation of a large online sexual health community (OSHC), this study explores consumers' motivations for engagement with OSHC. Findings contribute to the development of a new theoretical framework that reveals two main motivational patterns for consumer engagement with OSHCs: proactive motivations, such as community homophily, information diversity, language barriers, convenience, community moderation, inclusive language, and collaborative knowledge building; and reactive motivations, triggered by emotional distress, loneliness, perceived stigma and discrimination, confidentiality assurance, information gatekeeper, and need for social support. The cultural context moderates these motivations. Engagement outcomes include health empowerment, perceived value, sexual health confidence and wellbeing, relief and reduction in emotional distress, moderated by the perceived severity of users’ health conditions. The study advances understanding of digital consumer engagement in stigmatized health contexts and offers a theoretical framework for how individuals co-create knowledge, manage risk, and achieve empowerment through online peer interaction. The study has implications for policymakers, health communities, and medical organizations
Virtual influencer marketing: an empirical investigation of the critical factors influencing user engagement with virtual influencers
No full textInternational audiencePurposeThis study aims to examine the influence of specific influencer attributes (sociability, identity disclosure and number of followees) and a key post-level factor (emoticon use), along with their interactions, on user engagement with virtual influencers on social media.Design/methodology/approachUsing a data set of 1,852 posts from 173 virtual influencers, this study applies manual coding and text-mining techniques to extract influencer and post attributes for empirical analysis.FindingsResults reveal that sociability and emoticon use increase user engagement, whereas identity disclosure has a negative effect. Moreover, the positive impacts of sociability and emoticon use are weakened when virtual influencers follow a large number of accounts.Research limitations/implicationsThis study is based on data from virtual influencers in China. Future studies could consider other types of virtual influencers and contexts in other countries.Practical implicationsMarketers are advised to prioritize building a virtual influencer’s sociability and using emoticons to drive user engagement. They should also strategically manage followee count to avoid diluting a virtual influencer’ impact. Crucially, creators should avoid excessive identity disclosure to sustain user engagement.Originality/valueGrounded in the parasocial relationship theory, this research advances virtual influencer marketing literature by examining how influencer- and post-level factors, along with their interplay, drive user engagement with virtual influencers
Rethinking technology regulation in the age of AI risk
No full textInternational audienceThis paper argues that artificial intelligence exposes the shortcomings of traditional regulatory paradigms, challenging Easterbrook’s‘Law of the Horse’ view that general legal principles suffice. AI’s opacity, autonomy, and systemic risks demand riskinformed,technology-specific governance.We identify the pacing problem, where innovation outstrips regulatory capacity, andpropose a tripartite framework distinguishing functional, structural, and relational risks. Comparative analysis of EU, US, UK,andChinese approaches highlights divergent logics of precaution,market oversight, hybrid flexibility, and state control. Effectivegovernance requires embedding risk into policy design through adaptive, proportionate, and harmonised mechanisms, balancinginnovation with accountability. The paper underscores the urgency of global coordination and calls for interdisciplinary ISresearch to inform anticipatory, participatory, and ethically grounded regulation
Facing the facts of the Gaza genocide: Refusing complicity, organizing solidarity
No full textInternational audienceAs a collective, Organization has a strong commitment to exposing and challenging dominationand oppression, to amplifying scholarly activism, and to standing in solidarity with the oppressed,the dispossessed, and the Indigenous peoples of the world. Therefore, we cannot remain silentobservers of the genocide in Gaza, of the oppression of the Palestinian people, and of the political,academic and organizational systems that are complicit in it. In this editorial, we call on MOSscholars to approach and study the genocide in Gaza and the oppression of the Palestinian peopleas a form of organized violence rooted in settler colonialism and processes of racialization thatrender Palestinian life disposable, and sustained by corporate, state, and academic infrastructures.Careful analysis exposes how the systematic targeting of health, education, and knowledgeinfrastructures is entangled with organizational processes involved in arms production, digitalplatforms, finance, universities, and humanitarian logistics. Building on the critical tradition of thejournal, this editorial calls on Organization’s epistemic community to act in solidarity with thepeople of Palestine through constructing alternative knowledge infrastructures and instituting anacademic boycott of Israeli institutions. We urge scholars, editors, and students to reconfigureprofessional practices and mobilize their work against genocidal, colonial and oppressive organizin
