L’activité de design définie par la représentation visuelle
No full textInternational audienceLa culture visuelle dans les pratiques de conception constitue chez les designers autant un mode communicationnel de projet pour soi et ses clients qu’un outil pour concevoir. Cette culture particulière de la conception par la représentation visuelle incarne une culture propre au design malgré la multiplicité des activités des designers et du design. Elle se déploie et circule par l’adoption de normes et de codes et par l’appropriation du langage visuel. Notre article vise à comprendre la manière dont les designers se représentent leur activité de travail, par cet « agir créatif » reconnaissable chez les concepteurs designers du design social ou du design participatif. Plus spécifiquement, nous souhaitons analyser les représentations sociales, mentales et visuelles qui émanent de l’activité des designers en interrogeant leur utilisation de la représentation visuelle pour faire état de leurs pratiques et de leurs activités. Notre méthodologie se base sur la réalisation d’entretiens semi-dirigés auprès de dix designers1 français, qui développent des pratiques contemporaines (design de service, design d’interaction, design des politiques publiques, design fiction) en considérant la manipulation de visuels dans l’activité de conception des designers. Au cours de ces entretiens, le double diamant nous a servi de point de départ pour interroger plus largement les représentations sur leur propre activité, ainsi que l’usage de la représentation visuelle dans leur pratique professionnelle. La contribution de l’article réside dans le fait de mettre en perspective une analyse des représentations sociales et visuelles de l’activité de design par les praticiens eux-mêmes avec une analyse rétrospective de la culture de conception du design. Ainsi, nous valorisons la manière spécifique dont l’activité de design mobilise la représentation visuelle, comme forme d’expression et de légitimation professionnelle de sa culture de conception
A Typology of Circular Sport Business Models: Enabling Sustainable Value Co-Creation in the Sport Industry
No full textInternational audienceThere is a continuing interest in the relationship between sport and nature. As a new field, sport ecology explores the impact sport has on the natural environment and how sport organizations and individuals can promote sustainability. However, a critical element is still missing in the sport ecology discourse—the link between organizations’ sustainability efforts and their value co-creation processes. The circular economy can provide this link by decoupling the value co-creation of sport business models from their environmental impact and resource depletion. Based on an extensive literature review, this study provides a new theoretically derived typology of circular sport business models, including comprehensive reasoning about sustainable value co-creation processes in the sport industry. It explains how sport managers of all three sectors—for-profit, public, and nonprofit—can transition toward more sustainable and circular business practices and offer integrative guidelines for future research
La communication dans les approches de design participatif : matérialité et factitivité des objets de médiations
No full textNational audienceCet article explore les liens entre communication et design d’interactions en s’intéressant en particulier à la communication dans les approches de design participatif ou co-design. Dans la continuité d’études sur les processus de communication au sein des dynamiques de transformations sociales, l’article se focalise sur l’analyse de la matérialité des modes de représentation mobilisés dans les projets de recherche et conception participative. Il s’attache à l’analyse des médiations engendrées par la mobilisation de certaines matérialités médiatiques, pour articuler les enjeux, postures, savoirs et savoir-faire parfois antagonistes des participants en vue de co-produire des solutions au plus près de leurs besoins et aspirations. En s’appuyant sur la sémiotique et l’anthropologie de la communication pour développer une approche à la croisée des media studies et design studies, l’article se donne pour objectif de répondre au questionnement suivant : Quels modes de représentation mobiliser pour concevoir à plusieurs, selon les acteurs, les situations et les finalités de la communication ? Quel rôle joue la matérialité de la communication dans ces approches de design participatif pour négocier le sens d’un projet et ses usages potentiels
Fabrique éditoriale et médiations du travail politique de catégorisation de l'entrepreneuriat social
No full textNational audienceEn France, l’Entrepreneuriat social (ES) émerge au sein d’un espace catégoriel préexistant et conflictualisé : l’économie sociale et solidaire. Cela impose à des acteurs inégalement positionnés et légitimés dans le monde social, économique, institutionnel et politique de (re)composer et (re)négocier leurs (af)filiations. L’article questionne les procédés éditoriaux infra-ordinaires mobilisés par des acteurs promoteurs de l’ES au sein d’un objet textuel à vocation de cadrage orienté de l’ES : le Baromètre de l’entrepreneuriat social. Sa mécanique éditoriale, en organisant le concert de leurs voix, institue les parties-prenantes de l’ES et contribue au travail politique de sa prise de forme comme une catégorie fédératrice, c’est-à-dire à vocation rassembleuse et inclusive

The importance of climate policy uncertainty in forecasting the green, clean and sustainable financial markets volatility
No full textInternational audienceThis research represents the first empirical evidence highlighting the significant role of climate policy uncertainty in predicting the green, clean, and sustainable financial markets volatility. The analysis incorporates Gavriilidis's (2021) recently introduced news-based climate policy uncertainty index. To conduct this investigation, an advanced econometric approach, namely GARCH-MIDAS, has been employed, considering two sample periods: (i) full period (ii) COVID-19 period. Furthermore, the study reveals that climate policy uncertainty amplifies volatility of the S&P Green Bond Index, S&P Global Clean Energy Index, and Dow Jones Sustainability Index, rendering these indices highly sensitive to such uncertainty. Additionally, the out-of-sample analysis demonstrates climate policy uncertainty as a strong predictor, with the GARCH-MIDAS model displaying superior predictive accuracy. The findings of this research bear significant implications for strategies related to risk mitigation and diversification of portfolio particularly for investors, policymakers, and portfolio managers
Towards the development of an explainable e-commerce fake review index: An attribute analytics approach
No full textInternational audienceInstruments of corporate risk and reputation assessment tools are quintessentially developed on structured quantitative data linked to financial ratios and macroeconomics. An emerging stream of studies has challenged this norm by demonstrating improved risk assessment and model prediction capabilities through unstructured textual corporate data. Fake online consumer reviews pose serious threats to a business’ competitiveness and sales performance, directly impacting revenue, market share, brand reputation and even survivability. Research has shown that as little as three negative reviews can lead to a potential loss of 59.2 % of customers. Amazon, as the largest e-commerce retail platform, hosts over 85,000 small-to-medium-size (SME) retailers (UK), selling over fifty percent of Amazon products worldwide. Despite Amazon's best efforts, fake reviews are a growing problem causing financial and reputational damage at a scale never seen before. While large corporations are better equipped to handle these problems more efficiently, SMEs become the biggest victims of these scam tactics. Following the principles of attribute (AA) and responsible (RA) analytics, we present a novel hybrid method for indexing enterprise risk that we call the Fake Review Index (). The proposed modular approach benefits from a combination of structured review metadata and semantic topic index derived from unstructured product reviews. We further apply LIME to develop a Confidence Score, demonstrating the importance of explainability and openness in contemporary analytics within the OR domain. Transparency, explainability and simplicity of our roadmap to a hybrid modular approach offers an attractive entry platform for practitioners and managers from the industry
Board centrality and environmental disclosures: Evidence from the polluting Industries in China
No full textInternational audienceWe examine the association between board centrality and corporate environmental disclosure using hand-collected data from Chinese-listed firms in heavily polluting industries. We find that board centrality has a positive effect on corporate environmental disclosure. We also show that this positive effect emanates from the critical role of the board in monitoring and resource distribution, and its incentive to promote information transparency. Our results, which are robust to a set of robustness checks, have important implications for both regulators and investors.We examine the association between board centrality and corporate environmental disclosure using hand-collected data from Chinese-listed firms in heavily polluting industries.

Institutional forces, leapfrogging effects, and innovation status: Evidence from the adoption of a continuously evolving technology in small organizations
No full textInternational audienceAlthough SMEs’ innovation adoption has been widely studied, little research has explored how SMEs strategize a continuously evolving technology in a complex institutional context over time. Drawing from institutional perspectives, our case study, based on 44 interviews and field observation, seeks to analyze how institutional forces interact with the Wi-Fi adoption process at three small organizations with different innovation statuses. Results reveal the significance of institutional forces in shaping small organizations’ technology adoption process. At the knowledge stage, institutional forces stem from the champion’s advocacy and institutional pressures. At the persuasion and implementation stages, they are embedded in organizations’ actions in following the institutional trend and complying with institutional norms. At the confirmation stage, they can be observed in organizations’ shaping institutional changes or leapfrogging institutional trends. These insights challenge and extend the traditional linear perspective of innovation diffusion and contribute to the literature on technology adoption, digital transformation, innovation leapfrogging, institutional theory, and SMEs. Managerially, we propose three strategic responses (i.e., trend reformulation, service differentiation, complete transformation) that urge SMEs to utilize leapfrogging effects of technologies to renovate their innovation status
