Stable Heuristic Miner: applying statistical stability to discover the common patient pathways from location event logs
No full textInternational audiencePurpose: The classic heuristic miner algorithm has received lots of attention in the healthcare sector for discovering patient pathways. The extraction of these pathways provides more transparency about patient activities. The previous versions of this algorithm receive an event log and discover several process models by using manually adjustable thresholds. Then, the expert is left with the difficult task of deciding which discovered model can serve as the descriptive reference process model. Such a decision is completely arbitrary and it has been seen as a major structural issue in the literature of process mining. This paper tackles this problem by proposing a new process discovery algorithm to facilitate patient pathways diagnosis.Approach:To address this scientific challenge, this paper proposes to consider the statistical stability phenomenon in an event log, and it introduces the stable heuristic miner algorithm as its contribution. To evaluate the applicability of the proposed algorithm, a case study has been presented to monitor patient pathways in a medical consultation platform.Originality:Thanks to this algorithm, the value of thresholds will be automatically calculated at the statistically stable limits. Hence, instead of several models, only one process model will be discovered. To the best of our knowledge, applying the statistical stability phenomenon in the context of process mining to discover a reference process model from location event logs has not been addressed before.Findings: Practical implications-The results enabled to remove the uncertainty to determine the threshold that represents the common patient pathways and consequently, leaving some room for potential diagnosis of the pathways
The quadruple/quintuple helix model in entrepreneurial ecosystems: an institutional perspective on the space case study
No full textInternational audienceAlthough entrepreneurial ecosystems (EEs) have attracted increasing conceptual interest in the academic literature, little research has been conducted on their dynamics regarding the sociotechnological transformations that they undergo. To gain a bigger picture of this process, the theoretical underpinning is lacking. This research aims to address this theoretical gap by relying on the quadruple/quintuple (Q/Q) helix model to contextualize the dynamics fueling the development of EEs. We supplement this model with the institutional perspective to gain a better understanding of the dynamic interplay of EE institutions within their broader socioenvironmental context. Through an exploratory qualitative study based on secondary data from 1985 to 2021, we focus on the space EE as an illustrative case that has experienced major sociotechnological changes since the mid‐2000s. Likewise, we find that sociotechnological transformations lead to a change of focus in the knowledge production system, which is fostered by internal constraints and external opportunities. Indeed, informal institutions have a major influence on entrepreneurial dynamics by supporting an entrepreneurial culture within the Q/Q helix spheres, as they enable the inclusion of external actors in the innovation process. Ultimately, we point out the role of entrepreneurial support organizations in the inclusion of civil society and the environment in society and democracy‐based knowledge production systems to enhance the development of EEs
Technologies de contrôle : un enjeu organisationnel de lutte contre la fraude interne ?
No full textInternational audienceInternal fraud is a risk identified by organizations that have set up internal control services to protect themselves against it. Such services have emerged in organizations to strengthen the prevention of the risk of internal fraud, which has become an essential element of the risks to be managed in organizations. Employees can be controlled in the form of organizational, technological, or social control. Control technologies (video protection, geolocation, biometrics) facilitate the implementation of the fight against internal fraud by organizing surveillance. Several emblematic cases question the possible measures to reduce the risk of internal fraud. What technological control systems can a company put in place to optimize the detection of internal fraud and deter employees? We hypothesize that these tools effectively reduce cases of internal fraud. A qualitative study of forty-five employees of a life insurance company confronted with internal fraud highlights the need to strengthen processes, organize prevention, use legal and appropriate technologies, and impose sanctions.La fraude interne est un risque identifié par les organisations qui ont mis en place des services de contrôle interne afin de s’en protéger. Des services de contrôle interne ont vu le jour dans les organisations pour renforcer la prévention du risque de fraude interne qui est devenu un élément incontournable des risques à piloter dans les organisations. Le contrôle des collaborateurs peut s’exercer sous forme d’un contrôle organisationnel, technologique ou social. Des technologies de contrôle (vidéo-protection, géolocalisation, biométrie), en organisant la surveillance facilitent la mise en œuvre de la lutte contre la fraude interne. Plusieurs affaires emblématiques questionnent sur les mesures envisageables pour réduire le risque de fraude interne. Quels dispositifs une entreprise peut-elle mettre en place pour optimiser la détection des fraudes internes et dissuader les collaborateurs ? Parmi les formes envisageables de contrôle, quelle place occupe le contrôle technologique ? Nous formulons l’hypothèse que ces outils de contrôle technologique, intégrés dans le processus de contrôle interne, permettent une baisse effective des cas de fraudes internes. Une étude qualitative exploratoire auprès de 45 salariés conduite auprès d’une compagnie d’assurance vie confrontée à la fraude interne met en évidence la nécessité de renforcer les processus, d’organiser la prévention, d’utiliser les technologies licites et adaptées et de sanctionner

L’Europe, le cyberespace et la protection des données
No full textW. Gregory Voss (2022) "L’Europe, le cyberespace et la protection des données" (traduction). Encyclopédie d'Histoire Numérique de l"Europe, [en ligne], ISSN 2677-6588, mis en ligne le 25/10/22. Permalien : https://ehne.fr/fr/node/21643.The development of computer technology raised concerns for the privacy of the individuals to whom data being processed relates. Soon European nations began adopting data protection laws to protect the privacy of individuals, eventually regulating what had become known as “cyberspace.” To allow for the free flow of personal data within the European Union, while protecting the privacy of individuals, the regional block adopted EU-wide data protection legislation in 1995, which was then implemented in Member State law.The lack of harmonization of Member State implementing legislation and the development of new technologies led to the adoption of a uniform EU law in the form of the General Data Protection Regulation (GDPR), which has had international impact. The GDPR develops further individual rights and continues cross-border transfer restrictions, while including clearer extraterritorial application when the personal data of individuals in the European Union are collected, thus recognizing that cyberspace does not end at borders.Le développement de l’informatique a suscité des inquiétudes quant à la vie privée des individus dont les données personnelles étaient traitées. Les nations européennes n’ont pas tardé à adopter des lois de protection des données pour préserver la vie privée des personnes physiques, ce qui a abouti à une réglementation de ce que l’on appelle le « cyberespace ». Afin de concilier la libre circulation des données en son sein avec la protection de la vie privée, l’Union européenne adopte en 1995 une législation communautaire sur la protection des données qui est par la suite intégrée dans le droit des États membres.L’apparition de nouvelles technologies et les disparités législatives entre les États membres poussent l’Union à adopter une législation uniforme s’appliquant au niveau international, le Règlement général de protection des données (RGPD). Celui-ci renforce les droits des individus. Aux restrictions préexistantes sur les transferts de données à l’étranger s’est ajoutée une dimension clairement extraterritoriale de la loi quand les données personnelles de citoyens de l’UE sont collectées, ce qui prend acte du fait que le cyberespace ne connaît pas de frontières
La reprise du travail post-COVID : l’impact du soutien des besoins fondamentaux
No full textInternational audienceNotre recherche a pour objectif de mettre en avant l'impact du soutien des besoins fondamentaux (Deci & Ryan, 2000) sur la reprise de travail des salariés atteints de COVID, en s'appuyant sur la théorie de l'autodétermination. Nous menons 21 entretiens semi-directifs. L'analyse des textes mobilise le logiciel de traitement de données textuelles IRaMuTeQ développé par Ratinaud & Marchand (2012). Ce logiciel de lexicométrie est une interface de recherche pour les analyses multidimensionnelles de textes, dont les résultats sont le seul fruit de calculs statistiques. La classification lexicale permet de faire remonter différents foyers de préoccupations ou de perceptions exprimées par les participants. Les résultats obtenus confirment l'importance du soutien de trois besoins fondamentaux , et tout particulièrement du besoin de relation, pour la reprise de travail post-COVID

Expressions of the past: A practice-based approach of brand longevity visual translation in advertising
No full textInternational audienceWhile “an image is worth a thousand words”, there is limited advertising research looking at the practice of translating abstract marketing concepts into visual elements. This research considers the way that advertising professionals manipulate the concept of brand longevity and through which techniques they make it visible. Thirteen interviews conducted with art directors and graphic designers, as well as a visual content analysis on a corpus of 204 advertisements, lead to identifying a repertoire of visual codes. The findings further describe four types of longevity-themed advertisements: legitimizing, humorous, nostalgic, and aesthetic. This investigation contributes to the literature on brand longevity by showing what it looks like in practice. It also contributes to the broader literature on advertising by introducing the concept of the “visual mix” and the associated idea that graphic design is the craft of articulating visual codes, providing relevant solutions that fit the brand’s positioning
