Digital divide and artificial intelligence for health
No full textFNEGE 2, ABS 3International audienceSocial media platforms have become key intermediaries for ad campaigns, but concerns persist regarding the veracity of information presented in ads. In the health sector, false or unsupported claims in ad content can have real-world public health consequences. On these platforms, the display of ads is managed by recommendation systems that match the content of the ad to the interests of the user. This paper investigates whether the use of AI algorithms to recommend ads on social media platforms may help progress toward the Sustainable Development Goals (SDGs). We collected ads across all US states on Meta and Instagram during a period marked by increased public health concerns. Using a fine-tuned deep learning model, we fact-checked the content of these ads. The results of the fact-check show that only 0.2 % of the ads were classified as misinformation, and 15.41 % of the ads were classified as ambiguous. Both types of ads are less likely to be recommended to users located in wealthier states especially when health-related. Also, health-related ads classified as misinformation are more likely to be recommended to users in states with high percentage of people without health insurance. We argue that the use of recommendation systems contributes to widening the digital divide, which can hinder the achievement of SDGs
Developing a wiki-integrated workflow to build a living review on just sustainability transitions
No full textThis research proposal focuses on developing a living literature review on just sustainability transitions, addressing the challenges of information overload, knowledge synthesis and dissemination in academic research. We aim to assess the potential of Wikidata for creating an enriched, searchable academic knowledge graph on just sustainability transitions in order to facilitate navigation of existing academic knowledge and synthesis of research findings. To do so, we will conduct a meta-review of existing literature reviews, aiming to synthesize their findings by making the data they include interoperable and compatible with linked open data standards. Utilizing Wikidata, the project will collect and enrich bibliographic data, extract research results, and build a knowledge graph. The final output will include a literature review academic paper linked to this knowledge graph and a technical report about the challenges encountered in our literature review workflow. The project aligns with Wikimedia's strategic goals by contributing to filling content gaps on an important topic and by proposing an innovative way to build and disseminate social sciences results that could improve expert contribution to Wikimedia project and content trustworthiness
Severe Parvovirus B19 Infection in Patients with Sickle Cell Disease Hospitalized in Intensive Care Unit
No full textInternational audienceParvovirus B19 infection can lead to severe complications in patients with chronic haemolysis. The aim of this study was to describe severe Parvovirus B19 infections in adult patients with sickle cell disease (SCD). In this multicentre, retrospective, observational cohort study, adult patients with SCD admitted to intensive care units (ICUs) between 2011 and 2024 with acute Parvovirus B19 infection were included. Unsupervised analysis was performed including clinical and biological characteristics to identify clusters of patients with different outcomes. Clinical phenotypes were defined based on patient clustering. Parvovirus B19 genomes from ICU (n=15) and non-ICU control patients (n=15) admitted to the hospital during the same period were sequenced and compared. Sixty-one patients (52% female, median age: 29 years [IQR: 24;38]) from eight ICUs in France were included. Three clusters of patients were identified. From these clusters, three groups of patients with distinct clinical phenotype were identified: erythroblastopenia (n=26), bone marrow necrosis (BMN) and fat cerebral embolism syndrome (CFE) (n=17), and other vaso-occlusive manifestations (n=18). Length of stay in the ICU and hospital was longer in patients with BMN/CFE. There was no difference in Parvovirus B19 genotype or NS1 or VP1/2 amino-acid diversity between the groups. Similar results were observed between patients who were admitted to the ICU and those who were not. ICU patients with SCD and acute Parvovirus B19 infection presented three clinical phenotypes associated with different initial severity and outcome, but with similar Parvovirus B19 clades and amino-acid diversity
The role of information attainment on Front-of-Package labels and individual empowerment impacting boycott behavior
No full textInternational audienceIn response to consumer’s growing attention to the products they consume, front-of-package (FOP) labels have been developed to help them make healthier choices. This research aims to analyse the impact of information attainment on both FOP efficacy and individual empowerment and to measure the influence of FOP and individual empowerment on boycott behaviour. A quantitative approach was selected and a total sample of 353 respondents was collected and analysed using a partial least squares approach. The results show that information attainment affects two variables related to efficacy, namely consumer understanding and helpfulness, and three components of individual empowerment, namely consumer competence, self-determination, and consumer feelings of impact. Furthermore, our study reveals that boycott behaviour is determined by helpfulness and feelings of impact. This research provides better understanding of how consumers perceive FOP labels, how consumers are empowered, and how this influences behaviour

Breathe and let breathe: Breathing as a political model of organizing
No full textInternational audienceTake a deep breath. Although nothing is more natural or essential to human bodies than breathing, this simple yet vital act is the critical result of complex organizational, material, and political processes. We suggest that breathing can be thought of as a political model of organizing insofar as it shapes questions of life and death while rooting these ‘operationally’ in immediate, urgent, collective and more-than-human intra-action. Breathing is also a social act because the self is bound up with others in a fabric of relations upon which each person depends, and so breathing can serve as a trope for regenerating and rethinking social structures, institutions and organizing blueprints. We take the act of breathing – its literal and metaphorical (im)possibility and collective organization – as the focus of a reflection on relations among humans and between other living beings, humans, and their ecological surroundings. Re-thinking the question of whose breathing we care about and whose breathing counts, we offer a political model that embraces the mutuality principle for post-humanistic and post-anthropocentric organizing and community building. We thereby hope to ‘inspire’ and materialize new social and political realities for organizing our shared future, conceptualized as building a (scholarly) community of breathers who breathe and let breathe
Pathways towards member participation in governance of cooperatives: Conjunction of motivations and resources in the case of French community energy
No full textInternational audienceEnergy cooperatives promote a vision of democratic management of energy transition, but enacting this vision requires the active participation of members. In this paper, we aim to study the conditions leading to participation in the governance of cooperatives and how these conditions interact. Based on original data from a survey of members of a French energy cooperative, the study uses fuzzy-set qualitative comparative analysis to research how the resources available to an individual interact with their motivations to influence participative behaviour. Our empirical results show that a strong ecological orientation is a necessary condition for active participation and that, depending on their socio-economic situation, different types of members mobilize different resources to participate. We contribute to the literature on cooperative participation and 'green behaviours' in general by making theoretical propositions to explain participation behaviour as a conjunction of motivations, resources and opportunities.</div
System Feature Awareness and Retrieval Strategies in the Use of System Feature Awareness and Retrieval Strategies in the Use of Voice-Activated Devices Voice-Activated Devices
No full textInternational audienceUsers rarely take full advantage of the unprecedented possibilities offered by IT in the post-adoptive stage of use, creating a feature-use paradox. This paradox is particularly pronounced in the context of voiceactivated devices (VADs), such as smart voice assistants, as VADs require users to rely entirely on memory when interacting with them. In this setting, we theorize that users' ability to recall which system features are available is crucial for effectively engaging with VADs and can thus shed light on the feature-use paradox. We define IT Feature Awareness in the context of VADs by adapting the brand awareness concept from marketing research, and we develop a conceptual model rooted in adaptive system use theory that captures the expected impact of IT feature awareness on innovative use behaviors. We conclude this workin-progress by outlining our data collection plans and expected contribution to the post-adoptive IT use stream of the IS literature.</div
