Investigating the Links Between Cultural Values and Belief in Conspiracy Theories: The Key Roles of Collectivism and Masculinity

Research suggests that belief in conspiracy theories (CT) stems from basic psychological mechanisms and is linked to other belief systems (e.g. religious beliefs). While previous research has extensively examined individual and contextual variables associated with CT beliefs, it has not yet investigated the role of culture. In the current research, we tested, based on a situated cultural cognition perspective, the extent to which culture predicts CT beliefs. Using Hofstede’s model of cultural values, three nation-level analyses of data from 25, 19 and 18 countries using different measures of CT beliefs (Study 1, N = 5,323; Study 2a, N = 12,255; Study 2b, N = 30,994) revealed positive associ…

Generating a Located Synthetic Population of Individuals, Households, and Dwellings

Some of the new approaches in urban modeling, such as multi-agent systems (MAS) or activity-based models (ABM), require inputs in the form of disaggregated individual data. But for privacy protection reasons, such data is seldom available at this level. One way to get around this obstacle is to generate a synthetic population. This paper presents a method for generating a population from fully aggregated socio-demographic and geographic data. Based on French examples, this method can be reproduced anywhere in the country providing a relevant linkage between the characteristics of agents and those of urban spaces. The proposed method is subdivided into two steps. First, a population of agent…

Constraint Cellular Automata for Urban Development Simulation: An Application to the Strasbourg-Kehl Cross-Border Area

AcknowledgementsThe research presented in this chapter is part of the Smart. Boundary project supported by the Fonds National de la Recherche in Luxembourg and CNRS in France (ref. INTER/CNRS/12/02). The authors would like also to thank the Grasp Program of LISER for allowing cross-collaboration between the two teams based in Luxembourg and France.; International audience; Urban sprawl and space consumption have become key issues in sustainable territorial development. Traditional planning approaches are often insufficient to anticipate their complex spatial consequences, especially in cross-border areas. Such complexity requires the use of dynamic spatial simulations and the development of…

Proposition méthodologique pour l'exploration et la visualisa- tion des données de mobilité

National audience; Les sources de données de mobilité individuelle se sont aujourd’hui très diversifiées, aussi bien du côté des outils de collecte (smartphones, objets connectés, capteurs) que de celui d’applications (applications téléphoniques, simulation spatiale). Ces données partagent en général le fait d’être désagrégées et multidimensionnelles : elles se caractérisent par des attributs à la fois spatiaux (localisation, géométrie), thématiques (motif, mode de déplacement) et temporels (heure de début et de n, durée) qui décrivent les déplacements des individus (Peuquet D., 1994).

Using Power as a Negative Cue: How Conspiracy Mentality Affects Epistemic Trust in Sources of Historical Knowledge.

Classical theories of attitude change point to the positive effect of source expertise on perceived source credibility persuasion, but there is an ongoing societal debate on the increase in anti-elitist sentiments and conspiracy theories regarding the allegedly untrustworthy power elite. In one correlational ( N = 275) and three experimental studies ( N = 195, N = 464, N = 225), we tested the novel idea that people who endorse a conspiratorial mind-set (conspiracy mentality) indeed exhibit markedly different reactions to cues of epistemic authoritativeness than those who do not: Whereas the perceived credibility of powerful sources decreased with the recipients' conspiracy mentality, that o…

Open data, big data : quel renouveau du raisonnement cartographique ?

International audience; Le mouvement d’open data, qui permet l’accès gratuit à un grand nombre de données spatiales ou démographiques, associé au développement d’outils de cartographie ou de visualisation libres (SIG, programme), a permis l’augmentation de la production de cartes. Seulement, l’automatisation des traitements permise par ces outils tend à gommer le raisonnement cartographique et peut conduire à des erreurs de construction cartographique, d’autant plus que la phase d’analyse des données peut s’avérer de plus en plus complexe dans un contexte de big data (en tant que données massives, peu structurées et désagrégées). Le raisonnement cartographique est le processus menant d’une …

Complete mapping of the spin-wave spectrum in vortex state nano-disk

© 2016 American Physical Society.We report a study on the complete spin-wave spectrum inside a vortex-state nanodisk. Transformation of this spectrum is continuously monitored as the nanodisk becomes gradually magnetized by a perpendicular magnetic field and encounters a second-order phase transition to the uniformly magnetized state. This reveals the bijective relationship that exists between the eigenmodes in the vortex state and the ones in the saturated state. It is found that the gyrotropic mode can be continuously viewed as a uniform phase precession, which uniquely softens (its frequency vanishes) at the saturation field to transform above into the Kittel mode. By contrast, the other…

SIX NUANCES D'A-GREY-GATION L'influence du choix des unités spatiales d'agrégation sur la lecture et l'interprétation des résultats cartographiés

National audience; En même temps que les activités humaines se sont informatisées, les sources de données géographiques se sont diversifiées, autant du point de vue de leur production (smartphones, capteurs, simulation) que de leur gestion (modélisation, base de données et protocoles d’interrogation). Ces données de « nouvelle génération » partagent en général le fait d’être massives, désagrégées et multidimensionnelles. Elles se caractérisent par des attributs riches d’un point de vue spatial (localisation), thématique (type d’activité) et temporel (heure de début et de fin, durée). En contrepartie, leur volume et leur structure les rendent difficilesà manipuler (Batty, 2013 ; Kitchin, 201…
