A production planning model for biorefineries with biomass perishability and biofuel transformation
No full textInternational audienceWe model and solve a production planning problem over a discrete-time horizon of a biorefinery that treats different types of biomass and transform them either into bioenergy or biofuel. Both biomass and biofuel can be stored. Storage of biofuel serves to match the supply with the demand of both bioenergy and biofuel. Deterioration of biomass, which was rarely studied in the bioenergy production literature, is modeled and its impact on storage decisions is analyzed. The proposed model has two main characteristics: (i) controlling inventory of the perishable biomass while considering different ages for the stored biomass and (ii) biomass can be transformed into either bioenergy or biofuel, which in turn can be stored and then transformed into bioenergy. The applicability of the developed model is shown through several numerical experiments. The results show that first, perishability can lead to profit losses that cannot be neglected. Second, there is a threshold value on the perishability rate above which perishability does not have any longer impact on the profit. Third, storage and transformation of biofuel results in considerable increase in profit and smoother production at the facility even when there is a high fluctuation in price and demand. Fourth, when the decision maker imposes a maximum age on biomass to enhance quality and reduce health risks, the model provides guidelines on how to make this decision with the lowest impact
Employee frustration with information systems: appraisals and resources
No full textInternational audienceFrustration experiences have important organizational and individual consequences, particularly in today's workplaces strongly reliant on information systems (IS). However, recent research has neglected the importance of this emotion in organizations. We propose a model of frustration with IS that considers its IS-related antecedents, consequences, and potential moderators. Drawing arguments from appraisal theory and conservation of resources theory, we propose a characterization of frustration through cognitive appraisals of IS in organizations. We suggest that both positive and negative responses to frustration can occur depending on its degree of activation, as well as individual and contextual factors, thus providing a holistic model of the IS frustration experience
Consumers’ perceived value of Social IoT based online community: investigating social awareness processes surrounding smart kitchen robot appliances
No full textInternational audienceSituated within the broader Social Internet of Things (SIoT) paradigm, where objects autonomously communicate, learn, and establish social relationships (Machine 2 Machine and Machine 2 Human), this study investigates via Partial Least Square Structural Equation Modelling (PLS-SEM) the social awareness processes at hand and establishes the drivers of consumers’ perceived value of SIoT based online communities (OCs). We leverage the case of smart kitchen robot appliances, such as Cookeo by Moulinex, and a sample of female respondents (n = 335) from France who all own and use such SIoT kitchen robot devices. The model demonstrates that the perceived value of SIoT based OCs stems from three SIoT community related activities, mutual aid, participation, and enjoyment, that are respectively driven by three motivational factors, including the willingness to co-produce, the willingness to connect to others, and the willingness to learn from the community. The vibrant exchanges in these cooking OCs reveal evolving relationships’ configuration and demands among participants integrating SIoT technology reach in the meaning and historical specificity of cooking as a cultural practice. Our contributions relate to the identification of consumers’ perceived value of SIoT based OCs drivers and to the critical debate about gender in SIoT technology and services development
Does Bilateral Trust Matter During Mergers and Acquisitions Negotiations?
No full textInternational audienceWe examine the effect of bilateral trust on cross‐border mergers and acquisitions (M&As). Using a large European M&A sample, we find that bilateral trust facilitates deal announcement and completion. Bidder and target bilateral trusts towards each other are both important for deal announcement, but only bidder trust towards the target firm matters for deal completion. The effect of bilateral trust on deal completion is amplified in more complex transactions and when bidders face severe liability of foreignness. Moreover, bilateral trust between the parties is also associated positively with merger performance. These results support the importance of bilateral trust as a deal facilitator in negotiation settings characterized by contract incompleteness and liability of foreignness
Exploring the individual and joint effects of founders' and managers' experiential knowledge on international opportunity identification
No full textInternational audienceThis study aims to examine the individual and interactive effects of the founder’s prior experience and managers’ foreign market knowledge on international opportunity identification by early internationalizing firms (EIFs). We draw on a sample of 332 small and medium-sized EIFs from a South Asian country, viz. from the Bangladeshi apparel industry. This study adopts a survey-based quantitative research approach. A hierarchical regression modeling technique is used to test the contingency hypotheses. The results demonstrate that founding entrepreneurs’ prior experience and managers’ experiential knowledge are strong predictors of international opportunity identification. While we hypothesized for the joint negative effects of founders’ prior experience and managers’ market knowledge on opportunity identification, the results were non-significant, thus partially supporting the assumptions of agency theory. Our study provides valuable empirical insights into and supports the role of founders’ prior experience and managers’ foreign market knowledge in investigating international opportunity identification
Geopolitical risk and commodity future returns: Fresh insights from dynamic copula conditional value-at-risk approach
No full textInternational audienceIn this study, we investigated the effects of geopolitical risk (GPR) on commodity future returns by computing the conditional value at risk (CoVaR) and delta CoVaR using time-varying and static bivariate copula models. Our results indicate that there is generally a positive dependence between commodity returns and changes in GPR. Empirical evidence also suggests that there are only upside risk spillovers from GPR to commodity markets. The delta CoVaR results locate the greatest systemic risk in heating oil and maize commodities. Future research avenues, as well as policy and practical implications, are outlined
Does corporate governance affect the performance and stability of Islamic banks?
No full textInternational audiencePurpose This paper aims to investigate the impact of corporate governance practices on cost efficiency and financial stability for a sample of Islamic and conventional banks. In the analysis, the author uses a set of corporate governance variables that include, the board size, board independence, director gender, board meetings, board attendance, board committees, chair independence and CEO characteristics. Design/methodology/approach The author uses corporate governance data of Islamic banks that is unique in this field. In the analysis, the author also uses stochastic frontier analysis and panel vector autoregression models to quantify long-run and short-run statistical relationships between the operational efficiency of Islamic Banks and corporate governance practices. Findings According to the results, Islamic and conventional banks exhibit important differences in the effects of corporate governance practices on cost efficiency and financial stability. Results show that with a blind general adoption of corporate governance practices, Islamic banks may suffer a loss in their value since the adoption of the third layer of binding practices, over and above the already existing ones, imposed by the Sharia Board and the Board of Directors, may lead to cumbersome business operations. This conclusion is of importance to Islamic Banks since they struggle to survive in a very competitive international environment. Practical implications The author believes that the results may be of a certain value to regulators, policymakers and managers of Islamic banks. Based on the results, the author postulate that Islamic banks should select carefully international corporate governance practices. Social implications Islamic banks should not adopt additional third layer of binding practices as that would result lower performance and instability that would be damaging for the economy Originality/value This study employs a unique sample of Islamic banks that includes corporate governance data hand collected. Our findings of the corporate governance impact on Islamic banks performance and stability are therefore unique in the literature
Causal complexity of sustainable consumption: Unveiling the equifinal causes of purchase intentions of plant-based meat alternatives
No full textInternational audienceSustainable consumption has received much attention, although its antecedents are not fully elucidated. Existing studies are constrained by the assumption of symmetrical paradigms, emphasizing the net effects of antecedents without considering the complexity of sustainable consumption decision-making. This study draws on the theory of consumption values and the complexity theory to identify the complex combinations of consumption values (health, food safety, ecological, curiosity, novelty, prestige, avoidance of guilt) that explain consumers’ intentions to purchase plant-based meat alternatives (PBMA). An online survey was used to collect data from 252 meat eaters in the United States. Data were analyzed with fsQCA to identify the causal configuration of consumption values that explain meat-eaters’ PBMA purchase intentions. The fsQCA results revealed six heterogeneous combinations of the consumption values that result in high levels of purchase intention toward PBMA. The findings can be used by marketers to develop strategies for promoting sustainable consumption and PBMA
Hitting Net-Zero Without Stopping Flying: Increasing Air Travelers’ Likelihood to Opt-in to Voluntary Carbon Offsetting
No full textInternational audienceVoluntary carbon offset (VCO) programs give air travelers opportunities to neutralize their carbon footprint. Despite its potential, few existing studies have explained how to present VCOs that can effectively appeal to the sensibilities of travelers in different conditions. We designed three online experiments with strategies to motivate travelers to opt-in. We found travelers who receive concrete messages that emphasize specific actions are more likely to opt-in to VCOs when flying in the near future. In contrast, travelers receiving abstract messages that emphasize general initiatives are more likely to opt-in to VCOs when flying in the distant future. When travelers are allowed to choose their preferred carbon offset method, they are more likely to opt in, especially when they receive concrete messages that indicate specific actions but not general initiatives. These findings contribute to the aviation carbon offset literature and offer useful new insights for airline companies
