abstract = {Purpose



Social network platforms are considered today as a major communication mean. Their success leads to an unprecedented growth of user-generated content; therefore, finding interesting content for a given user has become a major issue. Recommender systems allow these platforms to personalize individual experience and increase user engagement by filtering messages according to user interest and/or neighborhood. Recent research results show, however, that this content personalization might increase the echo chamber effect and create filter bubbles that restrain the diversity of opinions regarding the recommended content.

Design/methodology/approach



The purpose of this paper is to present a thorough study of communities on a large Twitter data set that quantifies the effect of recommender systems on users' behavior by creating filter bubbles. The authors further propose their community-aware model (CAM) that counters the impact of different recommender systems on information consumption.

Findings



The authors propose their CAM that counters the impact of different recommender systems on information consumption. The study results show that filter bubbles effects concern up to 10% of users and the proposed model based on the similarities between communities enhance recommendations.

Originality/value



The authors proposed the CAM approach, which relies on similarities between communities to re-rank lists of recommendations to weaken the filter bubble effect for these users.},

abstract = {Social media have gained traction in advertising campaigns for luxury and fashion apparel using influencers, who shape trends of photography. To remain competitive, however, influencers depend on how they convey authenticity, which largely relies on the key visual elements of the photographs they post on social media. The purpose of this study is to explore the visual elements of the photography used by social media influencers and to compare the main photography trends in digital media. Specifically, it aims to explore how new photography trends such as urban background style and fashion models with large body sizes affect consumers. To accomplish this objective, an online experimental setting was prepared to compare the effects of an urban versus a solid background and a fashion model with a large versus a thin body size on perceived authenticity and purchase intent. The research finds that urban background and large body size of the model significantly increase digital engagement. These results are in line with the research hypotheses that allude to the perception of authenticity as the key construct behind the effects on digital engagement. This inquiry also evaluates the interaction effect of the urban background and large body size of the model on perceived authenticity. In doing so, the present research examines the mediation role of perceived authenticity on the intention to buy. The results contribute to updating theory about the influencers' role on digital engagement and photography trends in social media. It also shows that perceived authenticity exerts a mediating role between the effect of visual elements on purchase intentions},

abstract = {Selon l'Organisation mondiale du tourisme (OMT), la pandémie a réduit de 70 % le tourisme international en 2020. Dans les médias, l'arrêt des mobilités internationales se traduit par un discours sur « la fin du tourisme » ou la « mort du voyage ». À l'été 2020, la plupart des territoires français connaissent pourtant une saison estivale aussi, voire plus fréquentée que les années précédentes. Comment expliquer ce décalage ? En s'appuyant sur l'analyse critique des indicateurs statistiques du tourisme, des observations de terrain et l'étude des commentaires postés sur les plateformes de réservation touristiques, cet article propose l'hypothèse suivante : la pandémie révélé la fragilité de l'industrie internationale du tourisme, mais aussi son emprise sur les normes, les valeurs et les imaginaires de l'ailleurs et du temps « autre ». Échappant à l'industrie du tourisme et à ses indicateurs, les pratiques de vacances populaires ont résisté plus qu'elles ne se sont radicalement transformées. Surtout, elles sont devenues visibles et valorisées. Dans ce contexte, la notion de valence différentielle nous permet d'appréhender l'actuelle inversion des valeurs associées respectivement au tourisme international et aux vacances populaires.},

abstract = {Purpose-This study bridges the gap between sensory marketing and the use of the internet of things (IoT)in upscale hotels. This paper aims to investigate how stimulating guests'senses through IoT devices influenced their emotions, affective experiences, eudaimonism (well-being), and ultimately, guest behavior.The authors examined the potential moderating effects of gender.

Design/methodology/approach-Research conducted comprised an exploratory study, which consisted of interviews with hotel managers (Study 1) and an online confirmatory survey (n= 357) amonghotel guests (Study 2).

Findings-The results showed that while the senses of smell, hearing and sight had an impact on guests'emotions, the senses of touch, hearing and sight impacted guests'affective experiences. The senses of smelland taste influenced guests'eudaimonism. The sense of smell had a greater effect on eudaimonism andbehavioral intentions among women compared to men.

Research limitations/implications-This study concentrated on upscale hotels located in Europe. Further research may explore the generalizability of thefindings (e.g. in other cultures, comparison betweenhigh-end and low-end hotels).

Practical implications-Managers of upscale hotels should apply congruent sensory stimuli from allfive senses. Stimuli may be customized (?SoCoIoT?marketing). IoT in hotels may be useful in the aftermath ofthe COVID pandemic, as voice commands help guests avoid touching surfaces.

Originality/value-IoT can be applied in creating customized multi-sensory hotel experiences. Forexample, hotels may offer unique and diverse ambiances in their rooms and suites to improve guestexperiences.},

abstract = {This paper proposes a Model-Driven Architecture approach for the development of an embedded system validation platform namely Model-Based Security Analysis for Embedded Systems (MBSAES). The security properties are formally modeled and verified at an early stage of the design process of the system, which helps to reduce late errors and development time. A separation of the attack scenarios and the system design from the implementation details has been respected. To transform semi-formal models from SysML to NuSVM model checking platform, two Model-to-Text, horizontal and exogenous transformations have been implemented. The first one employs a programming approach with Java to create a Computational Tree Logic specification from an Extended Attack Tree, whereas the second one uses a template approach with Acceleo to generate NuSMV code from SysML structural and behavioral models. To illustrate our approach, a case study, involving attacks aiming to unlock car door systems, via signal jamming and code replaying, is considered. The results of this research will contribute to the automatic validation of system designs against security vulnerabilities via a database of extended attack trees building from existing atomic attacks.},

Drawing from several years of our research, we suggest that the design of such systems must be driven by a deep understanding of auditory cognition. In this article, we discuss two concrete approaches we take toward cognition-informed interface design - one that begins with sounds themselves to form explicit, contextualized, cognitive models, built on the foundations of large-data parsing infrastructure; and one that begins with the individual, built from intuition surrounding the influence of the cognitive state on perception. We point toward an unexplored and compelling future at their intersection.},

abstract = {The growth of e-retail has expanded to a wide range of product categories. E-retailers compete in a multichannel environment using several social media platforms (SMPs) where their product category and use of SMPs affect potential consumers' perception of product quality. Although studies have noted the potential of SMPs and differences between SMPs to support consumers in their information collection about products, the effect of different SMPs on consumers' perception of product quality remains unexplored. Based on a literature review, this research suggests a theoretical framework of the knowledge acquisition process for new consumers evaluating the quality of diverse retail products. Using network and information theory, this study proposes hypotheses to assess the effect of diverse e-retailer's product categories and different SMPs on consumer's perception of e-retail product quality for consumers unfamiliar with e-retail brands. After testing these hypotheses using primary data, results partially validate the theoretical framework. Research findings help practitioners to organise their e-retail products display across diverse SMPs and provide insights for scholars of e-retailing and digital media striving to acquire consumers online.},

abstract = {Purpose: The objective is to know what the mediating effect of the category of consumer products on sales performance is.



Methodology: Data from 216 e-commerce platforms were used using the Search-Experience-Trust (SEC) categorization. Two t tests were used to confirm significant differences between product categories and regression analyzes were performed to test the hypotheses.



Results: The results show that the ease of evaluating products before consumption has two main effects in electronic commerce: 1) they increase web traffic and 2) they decrease their conversion rate. However, the results also show that the ease of evaluating a product category directly influences online sales per visitor, since the mediating effect of the conversion rate is only partial.



Implications: This study contributes in practice to be able to determine predictive models related to the supply and demand of retail products in electronic commerce and shows a way to segment consumers who depend on their perceptions of product categories.



Originality/Value: This research, unlike what is in the literature, contributes to the study of electronic commerce from the perspective of the company, and not from the perspective of the consumer, in the performance of sales and conversion rates.

abstract = {To maximize the impact of an advertisement campaign on social networks, the real-time bidding (RTB) systems aim at targeting the most influential users of this network. Influence maximization (IM) is a solution that addresses this issue by maximizing the coverage of the network with top-k influencers who maximize the diffusion of information. Associated with online advertising strategies at Web scale, RTB is faced with complex ad placement decisions in real time to deal with a high-speed stream of online users. To tackle this issue, IM strategies should be modified in order to integrate RTB constraints. While most traditional IM methods deal with static sets of top influencers, they hardly address the dynamic influence targeting issue by integrating short time decision, no interchange and stream's incompleteness. This paper proposes a real-time influence maximization approach which takes influence maximization decisions within a real-time bidding environment. A deep analysis of influence scores of users over several social networks is presented as well a strategy to guarantee the impact of an IM strategy in order to define the budget of an ad campaign. Finally, we offer a thorough experimental process to compare static versus dynamic IM solutions wrt. influence scores.},

The Logics enable us to study buy-in by revealing the differing degrees of affective self-identification that underpin and color social practices, showing their inherently political nature. We exemplify the affective as well as social politics of buy-in with an account of Unity 3D, a market-leading game engine that underwent a major repositioning from ?fringe? to ?mainstream? markets, and discuss four poles of affective positioning with which to conceptualize technology buy-in.
