In a very uncertain and competitive economy, companies have to cope with external constraints such as environmental and social issues, to gain competitive advantage. Over the last thirty years, numerous initiatives have appeared to deal with socio-environmental issues. However, contexts are complex and dynamics. Many authors therefore point out the need to establish a systemic perspective in order to improve the integration of sustainable issues into all company activities: from strategic decision-making to the end of the project. In addition, companies need to reinforce the relationship between general corporate development and eco-design activities. Based on literature review, this paper assumes that the integration of sustainability can be improved by developing a coherent and system approach between strategic, tactical and operational levels. The authors have chosen to demonstrate this assumption by targeting the environmental aspect of sustainability as a first step of their overall research.In this view, this paper proposes a navigation system composed of three modules: strategic, tactical and operational. This navigation system provides some pragmatic roadmaps for integrating environment into the company. Each module is linked to the others by the use of appropriate metrics. Bottom-up and top-down or middle-to-sides strategies are fully supported.To test this proposal, the navigation system is experimented retrospectively into an industrial process from the textile industry. The comparison between the initial situation and the experimental results allows authors to highlights potential environmental improvements. Some recommendations are made to challenges companies to use this navigation system, which argues in favor of environmental improvements.

This article explores the managerial dimensions of big data phenomenon, focusing on the challenge of customizing an effective use model within companies. The central inquiry revolves around tailoring such a model to suit the specific needs of big data user companies. To address this, the study adopts a conceptual framework proposed by Surbakti and his co-authors, which delineates the effective use of big data. The primary methodology involves quantitative analysis of data gathered from 211 surveys completed by Armenian industry professionals. Examination of the collected data through statistical analysis reveals the presence of two distinct cohorts within the realm of big data users: "novice users" and "advanced users". The main theoretical contribution that we aim for in this research is empirically proving the global validity of the studied model and demonstrating its flexibility of application in these two types of use cases of big data. While the conceptual model is found to be applicable to both types of users, its implementation varies significantly between the two groups. Therefore, from a managerial point of view, our results lead a manager to think at first on the maturity of its company in terms of big data. Implementing a solution is not enough. By thinking in terms of novice vs advanced, it creates two different managerial courses of action. Moreover, we propose the variables a manager has to analyze depending on this maturity.

Analysing and monitoring users' engaged-behaviours continuously and under ecologically valid conditions can reveal valuable information for designers and practitioners, allowing them to analyse, design and monitor the interactive mediated activity, and then to adapt and personalise it. An interactive mediated activity is a human activity supported by digital interactive technologies. While classical metric methods fall within quantitative approaches, this paper proposes a qualitative approach to identifying users' engagement and qualifying their engaged-behaviours from their traces of interaction. Traces of interaction represent the users' activities with an interactive environment. The basis of our approach is to transform low-level traces of interaction into meaningful information represented in higher-level traces. For this, our approach combines three theoretical frameworks : the Self-Determination Theory, the Activity Theory and the Trace Theory. Our approach has been implemented and tested in the context of the QUEJANT Projet. QUEJANT targets the development of a system allowing the actors of Social Gaming to analyse players' engagement from an analysis of their activity traces. In order to demonstrate the feasibility of our approach, we implemented the whole process in a prototype and applied it to 12 players' interaction data collected over four months. Based on these interaction data, we were able to identify engaged and non-engaged users and to qualify their types of engaged-behaviours. We also conducted a user study based on a validation of our results by experts. The high prediction rate obtained confirms the performance of our approach. We finally discuss the limitations of our approach, the potential fields of application and the implications for digital behavioural interventions.

Our research deals with the development of a new type of game-based learning environment: (M)MORPG based on mixed reality, applied in the archaeological domain. In this paper, we propose a learning scenario that enhances players' motivation thanks to individual, collaborative and social activities and that offers a continuous experience between the virtual environment and real places (archaeological sites, museum). After describing the challenge to a rich multidisciplinary approach involving both computer scientists and archaeologists, we present two types of game: multiplayer online role-playing games and mixed reality games. We build on the specificities of these games to make the design choices described in the paper. We also present three modular features we have developed to support independently three activities of the scenario. The proposed approach aims at raising awareness among people on the scientific approach in Archaeology, by providing them information in the virtual environment and encouraging them to go on real sites. We finally discuss the issues raised by this work, such as the tensions between the perceived individual, team and community utilities, as well as the choice of the entering point in the learning scenario (real or virtual) for the players' involvement in the game.

Introduction: During the Covid-19 pandemic and the resulting visitation restrictions, digital tools were used in many nursing homes in France to allow the older adults and their relatives to maintain social contact via videoconferencing. This article adopts an interdisciplinary approach to analyze the processes that affect the use of digital technologies. Methods: Drawing on the concept of “mediation,” it seeks to shed light on how individuals embrace these tools in a relational situation. The interviews and observations undertaken among residents, their relatives, professionals, and the management head of seven nursing homes in 2021, make it possible to outline the different forms of practices and uses and to identify the factors leading to the variations observed. Results: While the key objective of these technical and technological tools is to compensate – on a functional level – for the communication problems and the isolation of individuals in order to promote residents’ “quality of life” by maintaining “social contact,” our study reveals that these tools’ uses and practices largely differ. It also shows considerable inequalities in terms of residents’ acquisition of subjective feelings of ownership of the tools. These are never attributed to isolated physical, cognitive, psychic, and social difficulties, but are influenced by specific organizational, interactional, and psychic configurations. Some of the structures analyzed revealed situations in which mediation failed, occasionally exposing the risk associated with seeking “ties at all costs,” or revealing a disturbing strangeness when residents were placed in front of screens. Some configurations, however, showed that it was possible to set up an intermediate space for the experience to unfold, which in turn opened up a space where individuals, groups, and institutions could experiment, allowing them to develop subjective feelings of ownership of this experience. Discussion: This article discusses how the configurations that failed to promote the mediation process reveal the need to assess the representations of care and assistance in the relationships between older adults, their loved ones, and nursing home professionals. Indeed, in certain situations, the use of videoconferencing, while seeking to produce a positive effect, risks displacing and increasing the effects of the “negative” associated with dependency, which may worsen individuals’ difficulties within nursing homes. The risks associated with the failure to take into account residents’ requests and consent explain why it is important to discuss how certain uses of digital tools may renew the dilemma between concerns for protection, on the one hand, and respect for autonomy on the other.

L’épidémie de Covid-19 a mis les établissements de santé en tension. Une réactivité importante a été indispensable pour appliquer les recommandations qui ont évolué en permanence selon le stade de la pandémie, mais également selon les connaissances et les ressources disponibles. Chaque établissement a dû déployer son propre plan de mobilisation interne, et adapter son fonctionnement et son activité en fonction de la cinétique épidémique. Une réorganisation complète de l’activité a ainsi été mise en place : arrêt de l’activité programmée, réaffectation des moyens humains, libération de lits, création de filières dédiées aux malades de la Covid, approvisionnements… Mais tout en mettant en œuvre ces changements majeurs, chaque établissement a dû assurer la continuité des soins pour les malades dont les séjours ne pouvaient être déprogrammés, assurer la sécurité des professionnels, organiser le travail à distance chaque fois que cela était possible, etc.

This article studies whether nudges – that is, gentle alterations of people’s behaviour – increase audit quality. Although the utility of nudges is well-established in behavioural sciences, their applicability and efficacy have been less studied in accounting and auditing. To bridge this knowledge gap, the study extends nudge theory to financial audits, offering experimental evidence of the impact of social norms and justification nudges on auditor behaviour. A factorial 2 × 2 between-subject experiment (social norms and justification) shows that nudges amplify professional skepticism, a critical indicator of audit quality. A follow-up eye-tracking experiment involving an audit task identifies the underlying cognitive mechanism of this effect; nudges heighten auditors’ visual attention to pertinent information, thereby refining their evaluations of audit evidence and increasing their professional skepticism.

La diversité cognitive est souvent marquée entre les différents investisseurs (business angels et capital-risqueurs) et les dirigeants de start-up. Cette diversité est à la fois source d’innovation et de mécompréhension entre les acteurs. Elle doit donc être coordonnée pour non seulement assurer la survie de l’entreprise mais aussi lui permettre de se développer dans un environnement technologique turbulent. À l’aide d’une étude de cas longitudinale comparative de deux start-ups en relation avec différents investisseurs, nous menons une étude exploratoire pour investiguer la fonction de coordination cognitive. Nous élaborons un modèle des qualités que doit réunir un acteur afin de pouvoir exercer cette fonction.

<div><p>Industry 4.0 (I4.0) is a manufacturing paradigm revolutionising production by integrating advanced technologies, like AI, for automation and data integration. However, research in I4.0 overlooks human factors, crucial for designing systems that enhance well-being, trust, motivation, and performance. To address this, international bodies have introduced Industry 5.0, aiming to balance technological advancement with human welfare. To transition towards this vision, an understanding of current human-technology interaction is essential. Through a conceptual model aiming to understand the psychological experience of workers within their environment, we identified the studied human factors, their antecedents, consequences, and methodologies. Additionally, we explored how future research can adopt a human-centred approach in designing and implementing technology. Analysis of 67 articles showed the psychosocial dimension of human factors like AI trust, worker autonomy, motivation, and stress are underrepresented. We observed a significant disconnect between empirical and non-empirical studies in terms of theoretical frameworks, variable selection, data collection methods, and research designs. Our findings highlight the necessity for experimental, theory-driven research in human-AI interaction, using a multi-method approach including perceptual, observational, and psychophysiological measures. Lastly, we discuss the integration of these findings into managerial practice to foster workplaces that are technologically advanced yet remain empathetic to human needs.</p></div>

L’interdisciplinarité suscite de nombreux intérêts scientifiques et théoriques. Même si elle est souvent prônée par les acteurs institutionnels, les exemples réussis se font rares dans la littérature. Cet article présente les résultats d’une étude menée sur 3 ans sur un modèle de formation interdisciplinaire articulant de la gestion de projet et du design dans une école d'ingénieurs. L’étude présentée met en lumière les modalités, les apports et les limites de la formation via une triangulation de données : des entretiens avec les étudiants, un questionnaire auprès des enseignants participants et un retour d’expérience des responsables de la formation. Les limites et perspectives futures permettront d’enrichir les recherches sur les formations interdisciplinaires en école d’ingénieur.
