Improving human collective decision-making through animal and artificial intelligence
No full textWhilst fundamental to human societies, collective decision-making such as voting systems can lead to non-efficient decisions, as past climate policies demonstrate. Current systems are harshly criticized for the way they consider voters’ needs and knowledge. Collective decision-making is central in human societies but also occurs in animal groups mostly when animals need to choose when and where to move. In these societies, animals balance between the needs of the group members and their own needs and rely on each individual’s (partial) knowledge. We argue that non-human animals and humans share similar collective decision processes, among which are agenda-setting, deliberation and voting. Recent works in artificial intelligence have sought to improve decision-making in human groups, sometimes inspired by animals’ decision-making systems. We discuss here how our societies could benefit from recent advances in ethology and artificial intelligence to improve our collective decision-making system
Fixed and rolling batching for order picking from multiple carousels
No full textInternational audienceThe carousel is an important automated storage and retrieval system. Customer orders to be collected from carousels are grouped into batches and the orders of a batch are collected simultaneously. We study two batching methods for picking from multiple carousels: (i) fixed batching, where all orders belonging to a batch are collected before the next batch is started, and (ii) rolling batching, where each time an order belonging to the current batch is completed, it is immediately replaced by a new order. For these methods, the main decision is respectively to allocate orders to different batches and to define a sequence for adding orders into batches. With the objective of minimising the total completion time, we develop models for fixed and rolling batching. Thanks to our collaboration with the company KLS Logistic Systems, we use real data to test and prove the efficiency of our models. With comparison to current batching strategies of real companies and to benchmark heuristics, our models yield a considerable time saving. Our findings also indicate that an increase in order size favours the rolling batching over the fixed batching. The models developed in this paper have been implemented and are currently being used in practice
“Shiny” crypto assets: A systemic look at gold-backed cryptocurrencies during the COVID-19 pandemic
No full textInternational audienceIn this paper, we empirically analyse the performance of five gold-backed stablecoins during the COVID-19 pandemic and compare them to gold, Bitcoin and Tether. In the digital assets' ecosystem, gold-backed cryptocurrencies have the potential to address regulatory and policy concerns by decreasing volatility of cryptocurrency prices and facilitating broader cryptocurrency adoption. We find that during the COVID-19 pandemic, gold-backed cryptocurrencies were susceptible to volatility transmitted from gold markets. Our results indicate that for the selected gold-backed cryptocurrencies, their volatility, and as a consequence, risks associated with volatility, remained comparable to the Bitcoin. In addition, gold-backed cryptocurrencies did not show safe-haven potential comparable to their underlying precious metal, gold
Value creation and appropriation of software vendors: A digital innovation model for cloud computing
No full textInternational audienceDo software vendors propose, create, and capture value in the era of digital transformation? Drawn on the literature of business models, digital innovation, and firms' capabilities, we examine this cutting-edge research question. We conducted a multiple case research of 10 software vendors operating in Germany and Austria. The thematic analysis yields a conceptual model that explains whether and how software vendors leverage cloud computing-enabled innovation for the digital boost, which is this study's primary contribution to information systems research. Software vendors use a complementary portfolio of information technology and organizational capabilities to innovate in their value proposition, creation, and capture

From play to pay: a multifunctional approach to the role of culture in post-merger integration
No full textInternational audienceThe literature on Mergers and Acquisitions (M&A), cultural differences between organizations have frequently been identified as one of the main challenges in the process of post-merger integration (PMI). Existing research has explored a broad variety of cultural differences in perceptions, such as those relating to expectations, norms, values and beliefs within the respective organizations, and how these affect the process and success of PMI. However, less attention has been paid to the relevance of the macro-societal context to PMI. The ambition of this article is, therefore, to advance our understanding of how macro-level societal factors define organizational cultures and affect the success of PMI
Consumers' perceived value of healthier eating: A SEM analysis of the internalisation of dietary norms considering perceived usefulness, subjective norms, and intrinsic motivations in Singapore
No full textInternational audienceConsumers' internalisation of social norms is at work when they make routine, healthier food choices in everyday contexts. We investigate the dynamics of this phenomenon in Singapore, where over 98% of consumer food products are imported. To study this, we propose, through a consumer perspective (n = 316) via Partial Least Squares Structural Equation Modelling (PLS-SEM), a model that establishes a positive relationship between perceived usefulness, subjective norms, and intrinsic motivations and the perceived value of healthier food. Subjective norms are themselves found to be a function of perceived barriers, facilitating conditions and personal innovativeness. Our framework contributes to establish a shift in the drivers of healthier food choices toward a more socio-culturally grounded decision-making approach that is particularly relevant to understand food consumption. We show that daily food routines (opposing the exceptional healthy food item) are encapsulated in perceived value of healthier eating. The data indicates further that to support healthier food product consumption, both policy makers and food providers must facilitate imported foods that meet quickly changing lifestyle requirements
The psychology of frustration: Appraisals, outcomes, and service recovery
No full textInternational audienceThis study fills a gap in the consumer emotions literature regarding customer frustration in a customer service setting. Most research on customer emotions has examined anger, happiness or affect in general, largely ignoring the particularities of frustration. Consistent with appraisal theory, we use five experiments to explore the different appraisal dimensions that define frustration and its relation to customer loyalty and satisfaction. Contrary to common belief, we show that frustration is not simply the result of goal-blocking, but rather of a more complex combination of appraisals which differentiate it from anger and lead to distinct effects on satisfaction and loyalty. We also examine how the effects of frustration on loyalty and satisfaction are mitigated by service recovery in a further experiment and an event reconstructive method. Our results test appraisal theory, inform theory on customer emotions and have important implications for our understanding of customer satisfaction and loyalty following frustrating customer service encounters
Writing Energy Economics Research for Impact
No full textInternational audienceWe explore the drivers of impact for energy economics research based on an analysis of citations generated by The Energy Journal articles. The focus is on non-topic generators of impact. Our regression analysis shows that these non-topic measures can explain a substantial proportion (about 20%) of variation in future citations. We apply these findings, integrated with prior research on effective economics writing style, to recommend how energy economics articles should be written to increase their impact. These recommendations center particularly around the importance of initial article information provided to the reader and article structure
Understanding the impact of symbolic and substantive environmental actions on organizational reputation
No full textInternational audienceResearch in corporate environmental practices has shown that stakeholders impose coercive and normative forces that drive firms to perform environmental protection actions. However, limited attention has been placed on how different constituents of stakeholders value the firm's environmental actions. By focusing on industry peers as a constituent of stakeholders, we examine how the firm's environmental actions impact its reputation. Based on institutional theory and signaling theory we propose that symbolic environmental actions negatively affect reputation, whereas substantive actions improve firm's reputation among its peers. Building on the notion of signaling process, the authors also observe that a firm's reporting practices moderate positively the negative effect of symbolic actions. Data from a sample of 213 publicly traded firms operating in polluting industries from 2006 to 2013 support these results. The findings emphasize the danger of using symbolic actions to signal environmental commitment in a context of high-involvement information search and opportunistic behaviors
