Ethics in military organisations : implementation in the battlefield and lessons for management sciences
2016
This research questions the idea of military ethics. Our work uses an analytical framework combining three different disciplines: Ethics of care, developed in moral philosophy, Stakeholder theory, from business ethics, New institutionalism theory, from management science. This framework is then applied on two different research fields: the first one deals with the study of battles where ethical stakes were particularly high: the battle of Alger, the Iraqi war, the Srebrenica battle.The second one is qualitative interviews with officers coming back from the battlefield: 10 US officers from the Iraqi conflict and 7 French militaries from Afghanistan. These two research fields are completed by…
Exergy recovery in regasification facilities – Cold utilization: A modular unit
2009
Abstract The paper deals with the problem of cold recovery for direct utilization both in the site of regasification facility and far from it. A modular LNG regasification unit is proposed having the regasification capacity of 2 billion standard cubic meters/year of gas. The modular plant is based on use of a power cycle working with ethane or ethylene which allows operation of cold energy transfer, contained in LNG to be regasified, in a range of temperatures suitable for multipurpose use of cold, reducing regasification process irreversibility. Some electric energy is produced by the power cycle, but the own mission of modular unit proposed is addressed to deliver cold suitable for indust…
A Stackelberg-game approach to support the design of logistic terminals
2014
This paper deals with the design of logistic terminals taking Sicily, in the South of Italy, as a case study. It focuses on consolidation terminals for truckers and addresses the problem of optimising location pattern and public share in investments. This problem is solved through a Stackelberg game between the designer and the collective of road carriers. So a bilevel approach combines a system-optimum problem, at the upper level, with the carrier equilibrium problem, at the lower level. The choice behaviour of the lower-level player is simulated by a random utility model. The output of the game suggests that private companies and society should share the investments and the public contrib…
The overstated generational gap in online news use? A consolidated infrastructural perspective
2021
Recent research by Taneja et al. suggested that digital infrastructures diminish the generational gap in news use by counteracting preference structures. We expand on this seminal work by arguing that an infrastructural perspective requires overcoming limitations of highly aggregated web tracking data used in prior research. We analyze the individual browsing histories of two representative samples of German Internet users collected in 2012 ( N = 2970) and 2018 ( N = 2045) and find robust evidence for a smaller generational gap in online news use than commonly assumed. While short news website visits mostly demonstrated infrastructural factors, longer news use episodes were shaped more by …
Rolling or Scrolling? The Effect of Content Type on Habitual Use of Facebook
2020
The paper investigates how content type (i.e., hedonic and utilitarian content) is related to satisfaction, habitual use, use intensity and discontinued use intentions in the context of social media services. The research model was empirically tested using a survey study (n = 142) that was conducted among Facebook users. The results show that hedonic content is a strong predictor of habitual use of and satisfaction with Facebook. In turn, utilitarian content has a positive effect on satisfaction; however, it does not significantly affect habitual use. Additionally, habit affects use intensity more than satisfaction but has no significant effect on discontinued use intention. These results s…
Les parcours de double réussite (sportive et scolaire) de normaliennes : entre "déclassement" et retour sur probabilité
2014
En ligne sur http://www.cereq.fr/index.php/content/download/11326/93292/file/Relief48.pdf; National audience; Dans cette contribution, nous nous intéressons aux parcours des normaliennes du département Sciences du Sport et Éducation Physique (du lycée jusqu'à l'entrée dans la vie active. Par leur double parcours d'excellence (sportive et scolaire), les normaliennes illustrent un projet doublement assigné au masculin : un projet d'excellence scolaire voire professionnel d'une part et dans un domaine (le sport / les STAPS) structurellement masculin, d'autre part. A partir d'une enquête par questionnaires réalisée auprès des normalien-ne-s ayant intégré le département EPS (puis 2SEP) de l'Écol…
AnMBR, reclaimed water and fertigation: Two case studies in Italy and Spain to assess economic and technological feasibility and CO2 emissions within…
2020
[EN] The use of anaerobic membrane bioreactor (AnMBR) technology on urban wastewater can help to alleviate droughts, by reusing the water and nutrients embedded in the effluent in agriculture (fertigation) in line with Circular Economy principles. The combination of AnMBR and fertigation reduces CO2 emissions due to the organic matter valorization and the partial avoidance of mineral fertilizer requirements. However, both AnMBR and fertigation still face technological and regulatory barriers that need to be overcome. These bottlenecks were tackled within the first Innovation Deal approved by the European Commission in 2016, and gave rise to several case studies on water reuse systems. The r…
Assessing the dynamic eco-efficiency of Italian municipalities by accounting for the ownership of the entrusted waste utilities
2021
Abstract This study evaluates and compares the dynamic eco-efficiency of municipalities with publicly owned, privately owned, and mixed ownership solid waste utilities by estimating the Meta-frontier Malmquist-Luenberger productivity index for a sample of 68 major Italian towns. On average, the eco-productivity of Italian waste service providers increased by 8% from 2016 to 2019. Although municipalities with private utilities improved their eco-productivity most, the differences among the three clusters reflecting utility ownership are not statistically significant. The results show that publicly owned waste operators drive technology and that the technological levels of private utilities h…
