Civilian volunteers in United Nations hot spots : what makes them intend to apply for yet another mission?
No full textInternational audienceThis study focused on United Nations (UN) civilian volunteers serving in “hot spots”, and tested a model to predict their intentions to apply for a new UN assignment. These individuals have characteristics of both assigned expatriates and self-initiated expatriates. In-Role Behaviours (IRB) and Organizational Citizenship Behaviours towards the Local Population (OCB-Locals) were related to sense of personal accomplishment, that in turn was related to intentions to apply for another UN assignment. Sense of personal accomplishment played a mediating role. Both the personality trait of agreeableness and the attitudinal factor of commitment towards the local population were predictive of IRB, but only agreeableness was predictive of OCB-Locals. Moderation effects were identified, but the direction of most of them was unexpected. For example, it was low openness to experience that strengthened the link between sense of personal accomplishment and intentions to re-apply. The study’s implications for expatriation research and for practice are discussed.<br/
The Way People Lie in Markets: Detectable vs. Deniable Lies
No full textInternational audienceIn a finitely repeated game with asymmetric information, we experimentally study how individuals adapt the nature of their lies when settings allow for reputation building. Although some lies can be detected ex post by the uninformed party, others remain deniable. We find that traditional market mechanisms, such as reputation, generate strong changes in the way people lie and lead to strategies in which individuals can maintain plausible deniability; people simply hide their lies better by substituting deniable lies for detectable lies. Our results highlight the limitations of reputation to root out fraud when a deniable lie strategy is available
Optimal Process Mining of Traces With Events and Transition Attributes With Application to Care Pathways of Cancer Patients
No full textInternational audienceContrary to event traces considered in traditional process mining literature, this paper addresses the problem of optimal process mining of traces of events and attributes associated with transitions. The problem is formally defined with rigorous description of the input event logs, the output process model, the event game specifying the images of traces in the model, and a non standard quality metric termed relevance for both the model and all model components. A dynamic programming algorithm is proposed to determine the optimal event game of each trace for a given process model. A multi-start local optimization algorithm built on an original concept of marginal relevance measure is developed for process model optimization. The proposed algorithm is shown to outperform benchmark algorithms on 40 generated test instances and be able to produce near optimal process model with an optimality gap of less than 4.46%. Results of this paper are also applied to a real case study of the care pathways of sarcoma patients. The event log representation is shown to be able to describe accurately the impact of the health state on the care pathways with only minor model relevance degradation. The proposed approach is shown to be able to generate process model at various precision levels and to compare the care pathways of cancer patients. It is also shown to generate better process model than the widely used process mining tools Disco and DFvM on both our relevance and the traditional fitness quality metrics. Note to Practitioners —This paper is motivated by our collaboration with the French cancer centre (Centre Léon Bérard) on data-driven modeling of sarcoma patient care pathways. The primary goal is to investigate the impact of patient health state such as cancer progression on the care pathways. We achieve this by original representation of care pathways by traces of events interleaved by health states. The original concept of “relevance” clearly measures the importance of each element in the process model. The faithfulness of the process model and its complexity can be easily controlled by precision parameters including least significance level of each model element and the number of layers of the model. A case study of Sarcoma patients is presented to show the importance of our care pathway representation, the superiority of our process mining algorithm, the difference of care pathways of four different patient management strategies, and how the health condition intervenes in different strategies
Un regard économique : la Doctrine sociale et les systèmes économiques
No full textInternational audienceLa Doctrine sociale de l’Église a souvent été accusée de ne pas porter un regard suffisamment structuré sur les systèmes économiques. Replacé dans son contexte par une lecture économique, ce jugement mériterait d’être nuancé. La capacité de la Doctrine sociale à analyser la réalité économique pourrait ainsi être reconsidérée et le rôle interdisciplinaire qu’elle est susceptible de jouer réévalué.<br/

Reflexiones en torno al papel de la antropomorfización de la marca de lujo y sus implicaciones en el sujeto : Una mirada crítica desde las ciencias sociales
No full textInternational audienceEl presente artículo contiene una reflexión sobre el papel que desempeñan en el mercadeo los conceptos de identidad, personalidad y antropomorfización de las marcas de lujo. La primera parte aborda una aproximación teórica a las características simbólicas del “prestigio vs la autenticidad” asociadas con la identidad. La segunda parte incluye una descripción sobre las principales dimensiones de la personalidad en las marcas de lujo. A partir del análisis en diversas fuentes, se concluye que existen cinco dimensiones: “tradición, modestia, elitismo, excentricidad y sensualidad”. En una tercera parte se reflexiona, a manera de crítica, sobre las implicaciones sociales que tiene esta antropomorfización en el sujeto y en su deseo por consumir las marcas de lujo para satisfacer el afán de emulación y el mantenimiento del estatus.<br/

Penser l’aide à la décision publique autrement. Amartya Sen et le débat sur l’information
No full textWorking Paper GATE 2403, February 2024Sen invites to think differently about the help of public decision making and the evaluation of public policies. Rather than mechanically deriving a recommendation from the aggregation of certain information considered to represent individual utility, he emphasizes why the debate on information is of crucial importance. He highlights the relevance of individual and collective, subjective and objective information, sentiments and scientific assertions, as well as the need to take their limitations seriously. A fair collective decision requires the combination of these different natures of information within a well-ordered public reasoning.Sen nous invite à penser autrement l'aide des décisions publiques et l'évaluation des politiques publiques. Plutôt que de déduire mécaniquement une recommandation de l’agrégation à partir de certaines informations réputées représenter l'utilité des individus, il montre l'importance du débat sur l’information. Il met en évidence la pertinence des informations subjectives et objectives, individuelles et collectives, les sentiments moraux des personnes et les énoncés scientifiques, en même temps que la nécessité de prendre au sérieux leurs limites. Une décision collective juste exige de combiner l’ensemble de ces informations, individuelles et collectives, subjectives et objectives dans le cadre d’un raisonnement public
