abstract = {This article investigates the role played by Information and Communications Technology (ICT) and specifically social media in reshaping the mediation (?Kulturvermittlung') processes enacted by museums along with their digital transformation. We apply a multi-methods research design, including qualitative research conducted within a selection of museums in France, an intercept study at Le Louvre Museum (Paris, France) and finally an online survey. Our findings concurrently put forward the concept of social mediation and illustrate the changing role of museum mediation processes that imply the transformation of visitor experience from a receptive format (consuming informative and entertaining content) to an interactive and collaborative format, through the use of social media and other ICT tools deployed and used complementarily to fulfill visitors needs and gratifications and foster what we call the visitor ?omni-visit experience'. Both theoretical and managerial implications are considered.},

abstract = {Several blogs and websites with a focus on social media marketing suggest that brands can benefit from fostering their Instagram account followers' fear of missing out (FoMO) by posting ephemeral content. Relying on an online survey with 550 followers of Instagram brand accounts and a scenario-based experiment with 535 participants, this article shows that content ephemerality triggers followers' FoMO, which increases brand account engagement and brand account fatigue. Brand account engagement (fatigue), in turn, positively (negatively) relates to brand attitude and brand attachment. Further analyses reveal that the total effect of followers' FoMO on brand attachment is positive and significant, while the total effect of FoMO on brand attitude is not significant. Moreover, content ephemerality has a negative and significant total effect on brand attitude. A key implication of these findings is that it is not beneficial for brands to foster their Instagram account followers' FoMO by posting ephemeral content.},

abstract = {Purpose



This article draws on a reasoned action perspective and the two fundamental dimensions (i.e. warmth and competence) of the Stereotype Content Model (SCM) to analyze customers' chatbot-related attitudes and usage intentions in service retailing. The authors investigate how chatbot, customer, and contextual characteristics, along with perceptions of chatbot warmth and competence, shape customers' chatbot-related attitudes. Furthermore, the authors analyze whether the customer generation or the service context moderates the relationship between chatbot-related attitudes and usage intentions.

Design/methodology/approach



The results are based on two studies (N = 807). Study 1 relies on a 2 (chatbot communication style: high vs low social orientation) × 2 (customer generation: generation X [GenX] vs generation Z [GenZ]) × 2 (service context: restaurant vs medical) between-subjects design. Study 2 relies on a similar number of respondents from GenX and GenZ who answered questions on scheduling a service with either the dentist or the favorite restaurant of the respondents.

Findings



GenZ shows more positive attitudes toward chatbots than GenX, due to higher perceptions of warmth and competence. While GenZ has similar attitudes toward chatbots with a communication style that is high or low in social orientation, GenX perceives chatbots with a high social orientation as warmer and has more favorable attitudes toward chatbots. Furthermore, the positive effect of chatbot-related attitudes on usage intentions is stronger for GenX than GenZ. These effects do not significantly differ between the considered contexts.

Originality/value



This research formulates future directions to stimulate debate on factors that service retailers should consider when employing chatbots.},

abstract = {Due to the extensive use of highly visual social media platforms such as Instagram, body image exposure has become a common practice. Specifically, the use of idealized women's bodies in different sectors of promotion and on social media has been subject to much criticism. The awareness of the negative outcomes of objectifying content triggered movements towards natural body exposure. However, empirical studies on the perceived effectiveness of this use are still needed. In this article, we compare how idealized versus natural women's bodies are perceived by Instagram users by means of an experimental procedure conducted with 700 users of this platform. We apply the Mann-Whitney U test and PLS-SEM to evaluate how physical attractiveness and idealization are related to the objectifying gazes. Our results suggest that overall publishing potentially objectifying content online is an accepted behavior, especially for more active Instagram users. Besides, both extremes of attractiveness, i.e. idealized beauty and perceived lack of attractiveness are subjected to stronger objectifying, than more natural-looking models. Thus, our paper contributes theoretically and empirically to the research on objectification by extending our knowledge of the factors that drive objectification and its acceptance among social media users. The implications of the emphasis on female bodily appearance on digital presence and the practices of digital influencers are discussed.},

abstract = {Dans cet article, plusieurs phénomènes potentiellement porteurs d'effets négatifs de l'usage des technologies de l'information et de la communication (TIC) et leurs interactions sont examinés, à savoir la dépendance au courrier électronique, la surcharge informationnelle et le technostress. Un modèle de recherche est conçu à cet effet et permet de démontrer que la dépendance au courrier électronique entraîne de la surcharge informationnelle, en plus d'être un facteur antécédent de deux générateurs de technostress : la techno-surcharge et la techno-invasion. De surcroît, la surcharge informationnelle a des répercussions perçues comme négatives sur la productivité et l'innovation dues aux TIC, alors que des effets positifs sur ces deux facteurs (techno-eustress) et neutres (non-technostress) peuvent être observés. La prise en compte de l'effet genre et des différences générationnelles entre les utilisateurs permet d'affiner ces résultats et d'approfondir la discussion de leurs implications théoriques et managériales. Notre travail apporte ainsi une contribution significative au courant de recherche émergent sur la face obscure ('dark side') où des effets positifs, négatifs ou neutres du fait de l'usage TIC peuvent émerger.},

abstract = {Dans le contexte actuel de transformation digitale des modes de fonctionnement des organisations et de leur design, cet article propose un recadrage conceptuel de la notion de rationalité des acteurs organisationnels afin de comprendre comment les choix que ces derniers effectuent tout au long de leurs interactions avec les technologies et systèmes d'information contribuent au modelage de changements sociotechniques sur le plan organisationnel et sociétal. Nous proposons une synthèse théorique sur les principales conceptions de la rationalité en sciences sociales. À savoir, l'approche dominante de la théorie du choix rationnel et les approches critiques développées notamment par Foucault, Habermas, Archer et Boudon. Plus particulièrement, l'article revisite et réconcilie les visions de ces deux derniers auteurs. Boudon préconise en effet une conception élargie (dite ordinaire) de la rationalité des acteurs telle que définie par Weber (1922), qui implique à la fois les dimensions utilitariste, normative et représentationnelle. Nous proposons d'associer à ce modèle les modes de réflexivité développés par Archer (2003) pour définir une nouvelle approche : la rationalité ordinaire réflexive. Trois idées clés fondent notre réflexion : (1) l'unité d'analyse de l'action sociale est l'individu ; (2) les structures sociales affectent et sont affectées par les actions individuelles ; (3) derrière chaque action individuelle, il y a un système de raisons associées à certains modes réflexifs que l'on peut définir. À ce titre, cet article propose un nouveau cadre analytique des changements sociotechniques actuels et à venir issus des interactions entre individus et technologies digitales.},
