Exclusion and inclusion on business markets : Impacts of the Internet-Of-Things (IoT)
No full textInternational audienceThe implementation of IoT solutions transforms business-to-business markets. This transformation is not limited to technological changes. It also affects the actors and activities that characterize markets. We argue that the possibility of forms of exclusion / inclusion, as interpreted in Luhmann's theory, has important consequences for IoT solutions. Different from prior studies which have focused on why and how market-related forces exclude actors from a market, this research aims to provide a comprehensive overview of possible exclusion phenomena linked to IoT implementation in business markets, concerning its affected actors, mechanisms, and consequences. Using ‘cold cases’, this research uses case study methodology to identify potential forms of exclusion and inclusion. It then develops a framework that identifies different situations of exclusion and inclusion. Finally, it suggests avenues for future research and provides managerial implications for the actors concerned in this context.<br /
Motivated information acquisition and social norm formation
No full textInternational audienceWe investigate how individuals select sources of information about peers' behavior and normative views, and the influence of this social information on individual behavior and both empirical and normative expectations. This is explored through two experiments (N=1,945; N=2,414) using a lying game, with and without known political identification. Our findings reveal a self-serving bias in the selection of information sources, with a preference for lenient sources (i.e., those presenting more tolerant empirical or normative information about lying), particularly when these sources align with an individual's political identity. We observe that being exposed to information that suggests lying is more socially acceptable increases lying behavior. Additionally, while people's normative expectations are not swayed by observing their peers' actions, these expectations are influenced by information about what peers believe is the right thing to do, underscoring the role of normative information in shaping social norms.</div

Resilience, efficiency fluctuations, and regional heterogeneity in disaster : An empirical study on logistics
No full textInternational audienceWhile resilience analysis can provide important insights into risk management strategies, research gaps exist in terms of logistics efficiency, regional economic environment, and spatial clustering patterns. Therefore, our study capitalizes on the dramatic variations in logistics activities among regions during COVID-19 to examine regional logistics resilience in the disaster and explore potential spatial clustering patterns. We measure regional logistics resilience through changes in performance outcomes, specifically efficiency fluctuation. To analyze spatial clustering patterns, (regional heterogeneity) presented by logistics efficiency, we propose a new multi-stage approach that integrates the data envelopment analysis with the K-medoids algorithm and analyzes data from the Chinese logistic industry. The results reveal that efficiency fluctuations exhibit distinct spatial distribution characteristics, with more pronounced negative fluctuations in areas of important logistics activities nodes and islands, and more widespread negative trends in coastal areas. Moreover, regions with high freight volumes and logistics specialization demonstrate a sustained high level and quality of logistics efficiency. Furthermore, consumption capacity and economic development appear to positively influence fluctuations in logistics efficiency. The findings hold implications for enhancing regional logistics resilience in the disaster and contribute valuable insights to regional logistics risk management.<br /
Performance Analysis of Multi-Tote Storage and Retrieval Autonomous Mobile Robot Systems
No full textInternational audienceMulti-tote storage and retrieval (MTSR) autonomous mobile robots can carry multiple product totes, store and retrieve them from different shelf rack tiers, and transport them to a workstation where the products are picked to fulfill customer orders. In each robot trip, totes retrieved during the previous trip must be stored. This leads to a mixed storage and retrieval route. We analyze this mixed storage and retrieval route problem and derive the optimal travel route for a multiblock warehouse by a layered graph algorithm, based on storage first-retrieval second and mixed storage and retrieval policies. We also propose an effective heuristic routing policy, the closest retrieval (CR) sequence policy, based on a local shortest path. Numerical results show that the CR policy leads to shorter travel times than the well-known S-shape policy, whereas the gap with the optimal mixed storage and retrieval policy in practical scenarios is small. Based on the CR policy, we model the stochastic behavior of the system using a semiopen queuing network (SOQN). This model can accurately estimate average tote throughput time and system throughput capacity as a function of the number of robots in the system. We use the SOQN and corresponding closed queuing network models to optimize the total annual cost as a function of the warehouse shape, the number of robots, and tote buffer positions on the robots for a given average tote throughput time and throughput capacity. Compared with robots that retrieve a single tote per trip, an MTSR system with at least five buffer positions can achieve lower operational costs while meeting given average tote throughput time and tote throughput capacity constraints.<br /
The Role of Contact-Tracing Mobile Apps in Pandemic Prevention : A Multidisciplinary Perspective on Health Beliefs, Social, and Technological Factors
No full textInternational audienceDuring the recent COVID-19 pandemic, governments implemented mobile applications for contact tracing as a rapid and effective solution to mitigate the spread of the virus. However, these seemingly straightforward solutions did not achieve their intended objectives. In line with previous research, this paper aims to investigate the factors that influence the acceptance and usage of contact-tracing mobile apps (CTMAs) in the context of disease control. The research model in this paper integrates the Unified Theory of Acceptance and Use of Technology and the Health Belief Model (HBM). The present study involved a diverse sample of 770 French participants of all genders, ages, occupations, and regions. Critical elements from the Health Belief Model, technological factors related to the app, and social factors, including the centrality of religiosity, were assessed using well-established measurement scales,The research's findings demonstrate that several factors, such as perceived benefits and perceived severity, social influence, health motivation, and centrality of religiosity, significantly impact the intention to use a CTMA.These findings suggest that CTMAs hold promise as valuable tools for managing future epidemics. However, addressing challenges, revising implementation strategies, and potentially collaborating with specialized industry partners under regulatory frameworks are crucial. This practical insight can guide policymakers and public health officials in their decision-making.<br /
The Relationship of Overall Justice to Flourishing and Job Performance : The Moderating Role of Materialism
No full textInternational audienceWe propose and test a new conceptual model in which overall justice is an antecedent to personal flourishing. Flourishing, in turn, partially mediates the relationship of overall justice to job performance and organizational citizenship behaviors directed toward individuals (OCB-I). These hypotheses are confirmed. However, high materialism weakens the relationship between overall justice and flourishing. Consequently, the mediated effects of justice on performance and OCB-I are moderated by materialism. In short, materialism sets limits on overall justice as an antecedent of flourishing and effective work behaviors.<br /
Exploring the Rhetoric of the Emotionally (Un) Intelligent CEO in Times of Crisis
No full textInternational audiencePurpose - Little is known about what emotionally un(intelligent) CEOs really say to their close collaborators within the boardroom. Would the rhetoric content differ between an emotionally intelligent and an emotionally unintelligent CEO, especially during a crisis? This chapter aims to answer this question.Study Design/Methodology/Approach - 40 CEOs of large corporations were asked to deliver a verbal address to their board members in reaction to a vignette describing a critical situation for the company. Participants were provided with the Schutte self-report emotional intelligence (EI) test. The verbal content of CEOs' closed-door discourses was analyzed using Cognitive-Discursive Analysis (CDA) and, subsequently, Geometric Data Analysis (GDA).Findings - The results revealed that CEOs with low EI tend to evoke unpleasant emotions, talk about competition, and often blame some – or all – of the board members for their (poor) actions in comparison to CEOs with high or medium EI. In contrast, CEOs with high EI tend to use terms in relation to decision or realization and appear to be more cooperative than those with lower EI and were also ready to make decisions on behalf of team. Originality/Value - Previous research has mainly focused on CEOs' public speeches. But the content of CEOs' speeches within the boardroom might noticeably differ from what they would say in a public address. The results of our exploratory study can serve CEOs as a basis toward improving their closed-door rhetoric during a crisis. Research Limitations - It would be interesting to enlarge the size of our population in order to strengthen our statistical analyses as well as explore other cultural and linguistic environments and other channels through which emotions can be expressed (e.g., human face, gesture, vocal tone).<br /
