Leadership, team cohesion and family firms’ performance
No full textInternational audienceThe purpose of this study is to determine the moderating effects of team cohesion and knowledge sharing on the performance of teams that utilise empowering leadership using a multiple regression analysis on a sample from three departments within 114 family firms in Lebanon. The results suggest that there is a significant relationship between empowering leadership and team cohesion and that knowledge sharing and team cohesion have an indirect influence on team performance. Our study provides important insights regarding team cohesion and knowledge sharing in empowering leadership practices in the Middle East. More importantly, our paper underlines how critical team performance is by highlighting the fact that a willingness to share skills, expertise and know-how benefits all team members and groups of a department or managerial structure. Group cohesiveness is crucial for a leader and for a firms management team and team performance
Adoption of Industry 4.0 technologies by organizations: a maturity levels perspective
No full textInternational audienceThis study employs a structured literature analysis considering Industry 4.0 technologies and their adoption stages (intention, adoption, implementation, routinization, continuance, and diffusion). We identify the technology adoption stage for each technology type, which in turn supports a maturity level categorization, as well as future research suggestions and challenging open research questions. By considering an integrated view of all the adoption stages of Industry 4.0 key technologies, we reveal the key technologies and their development stages, as well as a novel maturity level categorization perspective. The proposed categorization brings valuable research insights in the form of guidelines for practitioners and decision-makers interested in gaining a deeper understanding of the maturity level of key Industry 4.0 technologies
Plus de contrôle du temps de connexion, moins de stress : effets de l’utilisation des applications de contrôle parental sur le bien-être des parents
No full textThème du congrès : « Marketing et Hospitalité : Entre authenticité et exigence de durabilité »International audienceToday, children’s smartphone overuse and digital addiction are among parents’ top concerns. To help address this issue, IT firms have developed services to help parents monitor child screen time. The literature on the impacts of parental control tends to focus on the well-being of children, often overlooking the effects of parenting control on the well-being of parents. This research investigates the psychological outcomes associated with the delegation of parental control to an app. We conducted one survey and two experiments among samples of parents. Our results show that delegation of parenting control to an app improves well-being by decreasing psychological overload and increasing parental efficacy. Our findings also suggest that parental control based on strict restriction of screen time is perceived to be more helpful to increase parental efficacy and well-being than educational tracking. Implications for IT companies are discussed.La surutilisation des smartphones et la dépendance numérique des enfants comptent parmi les principales préoccupations des parents aujourd'hui. Des applications existent toutefois pour aider les parents à monitorer le temps d'écran des enfants. La littérature sur les effets du contrôle parental s’est plutôt focalisée sur le bien-être des enfants, négligeant les effets de ce dispositif le bien-être parental. Le but de cette recherche est d'étudier les effets psychologiques associés à la délégation du contrôle parental à une application. Une enquête et deux expériences ont été conduites auprès d'échantillons de parents. Nos résultats suggèrent que la délégation du contrôle à une application améliore le bien-être en diminuant la surcharge psychologique et en augmentant l'efficacité parentale. Le contrôle parental basé sur une restriction stricte du temps passé devant un écran semble plus utile pour augmenter l'efficacité et le bien-être des parents que le suivi éducatif. Des implications pour les entreprises sont discutées
Hyperloop, une mythologie de marchés
No full textInternational audienceThis paper studies how a market is being structured around Hyperloop, the hyper-speed train proposed in 2013 by Elon Musk. We show that Hyperloop carries the mythology, in the Barthian sense, of the possibility for humans to master time and space. We link semiology and materiality and show that meaning is constructed through texts and narrative. Their specificity can influence the structure of markets and what circulates in them. We develop the concept of ambiguous materiality: a dichotomy between the materiality of a technological object and its markets, enabled by the mythological nature of the object.Cet article étudie la manière dont un marché se structure autour de Hyperloop, le train à hyper grande vitesse, proposé en 2013 par Elon Musk. Les auteurs montrent que Hyperloop porte la mythologie, au sens barthien, de la possibilité pour l’humain de maîtriser le temps et l’espace. Ils lient sémiologie et matérialité, et montrent que le sens est construit au travers des textes et du récit, dont la spécificité peut influencer la structure des marchés et ce qui y circule. Ils développent le concept de matérialité ambiguë : une dichotomie entre la matérialité d’un objet technologique et ses marchés, permise par la nature mythologique de l’objet
Local public innovation: an analysis of its perceived impacts on public performance
No full textInternational audienceThis article explores public innovations implemented by local authorities, which consider them as a key means of improving their performance in response to a restrictive context. The authors thus propose to grasp the impacts of these innovations in terms of perceived performance from a global and multidimensional point of view. Based on a quantitative study conducted among French local authorities, this research first presents the results obtained from a theoretical point of view, providing insight into the multiple impacts of implementing innovations within the public sector. Then, at the managerial level, the study identifies specific impacts for each type of public innovation, the aim being to structure the innovation portfolio of public organisations. Points for practitioners An increasing number of innovations are being introduced in the public sector. However, the impact of these innovations on public performance is often not assessed. That is why by focusing our research on French local authorities, we guide managers both in analysing this influence by distinguishing several types of innovation and performance, and in building a portfolio of innovations in line with the internal resources of their local authority, as well as the public service provided in response to the needs of the territory

Collusion and Predation Under Cournot Competition
No full textThis paper studies how predation strategies can affect the sustainability of collusion. We demonstrate that in the presence of few competitors collusion may be sustained at equilibrium for intermediate discount factors. In such instances predation implies that punishment strategies will yield low subgame perfect payoffs, thereby making collusion easier to sustain. For low discount factors collusion is not sustainable because of the high incentives to deviate to Cournot-Nash strategies. Moreover, for high discount factors it is always optimal to predate colluding firms, thus contrasting with much of the earlier literature showing that collusion is only achievable by sufficiently patient firms
TRANSATLANTIC DATA TRANSFER COMPLIANCE (28 B.U. J. SCI. & TECH. L. 158 (2022))
No full textInternational audienceData play a central role in the economy today. Nonetheless, the main trading partner of the United States-the European Union-places restrictions on crossborder transfers of personal data exported from the European Union. Destination countries must benefit from a decision by the European Commission that their data protection practice is "adequate" to import data, or transfer tools must be used to further protect those data. The United States does not benefit from such a decision and an arrangement that previously allowed data to continue to flow to the United States-the Privacy Shield-was invalidated by the Court of Justice of the European Union in 2020 in a case that is known as Schrems II. This study focuses on EU-U.S. personal data transfers. It provides a holistic view of the legal parameters involved in transatlantic data transfer compliance post-Schrems II, relevant developments past and future, and potential compliance actions, supplemented with relevant guidance and an analysis of enforcement actions. Such compliance is considered the most difficult task of privacy professionals today. The aim is to give a fuller understanding in this context of the EU General Data Protection Regulation (GDPR), which sets out the crossborder data transfer restriction, with a view to potential pathways to navigate those challenges. Following the Introduction, this study dives into both the cross-border transfer restriction contained in the GDPR, and into the Schrems II ruling. EU-U.S. negotiations to try to build a replacement for the Privacy Shield are discussed. A new 2021 version of the standard contractual clauses transfer tool, used to allow data exports, is analyzed. In addition, the requirement to respect the essence of fundamental rights and freedoms set out in the Schrems II judgment is explained. Supplemental measures to ensure data protection and to allow transfers to jurisdictions with problematic legislation, such as the United States (with its surveillance laws), are detailed. Furthermore, European Economic Area data protection enforcement action in the domain of cross-border transfers is studied, including a recent case relating to the use of the popular Google Analytics tracking cookies. Finally, lessons for compliance are drawn, prior to concluding remarks

Contribution of Psychological Entrepreneurial Support to the Strengthening of Female Entrepreneurial Intention in a Women-Only Incubator
No full textInternational audienceThis article explores the contribution of psychological entrepreneurial support, based on same-gender group mentoring, to the strengthening of female entrepreneurial intention in the specific context of a women-only incubator. In other words, it examines the combined effect of gender-based differentiation and group dynamics on the process of incubating women entrepreneurs. Indeed, according to the literature on female entrepreneurship, women entrepreneurs are faced with specific challenges that influence their entrepreneurial intention such as a lack of self-confidence, caused by gender stereotypes, and conflict between family life and entrepreneurial career. More precisely, our research aims to determine how psychological entrepreneurial support is implemented in the incubation process to overcome these specific challenges, and the mechanisms for strengthening female entrepreneurial intention analyzed at both intrapersonal and interpersonal levels. Thanks to a qualitative methodology, our findings suggest that psychological entrepreneurial support delivered via same-gender group mentoring, at the beginning of the incubation process, reinforces female entrepreneurial intention, thanks to a mechanism of external approval and a process of deconstruction of gender stereotypes about female entrepreneurship. Role modeling provided by same-gender group mentoring facilitates the identity work of women entrepreneurs in search of entrepreneurial legitimacy and enables them to overcome various psychological barriers related to a lack of self-confidence or pressure stemming from the family environment. We discuss the implications of our findings on related research into business incubators and the design of mentoring programs adapted to the needs of women entrepreneurs. \textcopyright 2022 Bueno Merino and Duchemi
