Chercheuse, chercheur, êtes-vous « techno-vulnérable » ?
No full texthttps://theconversation.com/chercheuse-chercheur-etes-vous-techno-vulnerable-212632International audienceLe pain et le beurre de tout scientifique sont les données qu’il recueille au fur et à mesure de ses recherches, qu’elles soient terrain ou à partir de bases de données, qu’elles soient qualitatives ou quantitatives, ou les deux. Dans tous les cas de figure, le chercheur s’appuie sur ses données pour peaufiner des théories existantes, élaborer des hypothèses, confirmer des modèles, bref pour apporter à la science une valeur certaine qui permettra, l’espère-t-il (tout comme les revues scientifiques qui le publient), une amélioration de ce que l’on pourrait nommer la condition humaine

Chez nous, chez vous, à la manière Victoria
No full textEtude de cas - Collection ICN business school à la CCMPPublic- Etudiants en L3, Master, Ecoles d'ingénieurs, Mastères spécialisés- MBASoko Gonzales et Olivier Pierson ont fondé une société en 2013, laquelle est un ensemble de logements à louer idéalement situés dans des secteurs touristiques clés de Nancy, où les visiteurs viennent séjourner, quelques jours, semaines ou même quelques mois. Un concurrent sans scrupules a décidé de leur faire la vie dure. Soko et Olivier ne peuvent opter pour le statu quo. Ils doivent revoir leur offre, sans trop réduire leurs bénéfices et surtout, en mettant en avant les facteurs différenciateurs qui leur permettront de se démarquer d'une concurrence qu'ils jugent déloyale, et ce, en maximisant leur présence sur Internet. Comment s'y prendre
Gender and satisfaction of basic psychological needs: an exploratory study of pottery crafts in Latin America
No full textInternational audiencePurpose: This paper analyzes the relationship between gender and the satisfaction of basic psychological needs in the artisanal pottery sector in Latin America. Methodological design: We surveyed 195 owners/managers of small family businesses operating in artisanal communities in three Latin American countries: Mexico, Honduras, and Colombia. We used structural equation modeling to offer evidence of factorial invariance of the measurement instrument across genders. Results: We found that women artisans seem to be more satisfied than men in meeting their need for autonomy and competence, revealing an important benefit of artisanal activity. No significant difference was found in relation to the fulfillment of the need for relatedness. Research limitations: The limitations of this research are derived from the sampling method, which was mainly driven by practical, financial, and logistical restrictions rather than by theoretical criteria. Nonresponse bias may have also affected our results. Findings: It is important for the artisanal sector to find motivational factors that contribute to the continuity and development of the sector
The reaction of the metal and gold resource planning in the post-COVID-19 era and Russia-Ukrainian conflict: Role of fossil fuel markets for portfolio hedging strategies
No full textInternational audienceThe prime objective of this article is to examine the policy-making role of metal markets, gold resources, and clean energy markets in the post-COVID-19 era and the Russia-Ukrainian military conflict. In doing so, we analyze the role of fossil fuels, clean energy, and metals markets, considering the military conflict in Ukraine in 2022. The study employs event study methodology (ESM), Total connectedness index (TCI), and network analyses. The results indicate that natural gas and clean energy prices are less affected by conflict in the aftermath of an invasion than traditional energy and metals markets. In addition, we observe an increase in the TCI in the energy markets during announcement days. The TCI of the metals market is greater than that of the energy market. According to network connectivity, the key asset class transmitters of the shock in Europe are the Geopolitical index (GPR), gold, and the clean energy stock index (ERIX). The U.S. markets are less affected by the situation in Ukraine. The average hedge suggests that the optimal hedge differs from one market to the next, with fossil fuels and renewable energy, respectively, being more hedge effective and reducing risk by an average of around 0.80 and 0.59, given their ability to function as a hedging instrument
The Impact of the German Fuel Discount on Prices at the Petrol Pump
No full textInternational audienceAbstract This paper investigates the price impact of the fuel discount in Germany, which was introduced between June and August 2022 to partially compensate increased energy costs. Using the augmented synthetic control method (ASCM) to construct the counterfactual, we provide quantitative evidence to the heated debate concerning the impact of this policy tool and find the fuel discount to have decreased consumer prices of petrol (diesel) by at least 0.30 euro per litre (0.10 euro per litre) on average. The results are robust to various sensitivity checks. Thus, oil companies and petrol stations decreased prices for consumers and passed on about 85 % (65 %) of the discount in case of petrol (diesel). Moreover, we do not find signs of excessive price increases in anticipation of the fuel discount
Facilitating knowledge creation and team performance through behavioral integration and skill-based identity
No full textInternational audienceBuilding on social identity theory, the paper sheds new light on knowledge creation and performance within teams by enhancing our understanding of the role played by shared skill-based identity on knowledge creation and team performance. Besides addressing team coordination issues, this study helps bridge the gap between shared skill-based knowledge and knowledge creation as well as team performance. Based on two field studies, the authors found that (1) a shared skill-based identity leads to higher behavioral integration; (2) having skill-based knowledge enhances shared skill-based identity; (3) behavioral integration mediates the shared skill-based identity–team performance relationship. Overall, our findings demonstrate that shared skill-based identity plays a crucial role in team performance and knowledge creation by enhancing behavioral integration. However, although shared skill-based knowledge positively impacts shared skill-based identity, it has no direct effect on knowledge creation and team performance. The authors hence demonstrate that the factors influencing team performance are complex and individuals need to feel integrated in teams to create knowledge. Furthermore, the study provides empirical evidence that may advance the study of team performance and inform managers on how to form effective teams. For instance, the authors suggest that, when forming teams, managers should consider how each potential member defines their identity
Uncovering the Hidden Factors of Resilience: Supply Chain Ecocentricity, Exploitation, and Exploration
No full textInternational audienceThis article sheds light on often overlooked organizational antecedents that build supply chain resilience by drawing on knowledge management theory and the resource-based view because of their focus on exploitation and exploration as capabilities related to organizational learning. It was examined whether the relationships between supply chain ecocentricity and supply chain exploitation and exploration practices enable supply chain resilience. It was also determined whether environmental uncertainty would affect the relationship between these enablers and resilience. Manufacturing companies operating in France were surveyed and variance-based structural equation modeling was used to analyze primary data from 405 completed questionnaires. Ecocentricity, driven mainly by secondary stakeholders, was found to influence supply chain resilience as well as the exploitation and exploration of resources and capabilities, confirming that they are enablers of supply chain resilience. Firms should be aware that secondary stakeholders cannot be neglected in the supply chain network, because they contribute to knowledge management and a better understanding of market contingencies and in turn improve supply chain resilience. The original contributions of this article are to demonstrate the relevance of the ecocentricity perspective and its role in helping achieve resilience in supply chains
