Discours de la “symbiose judéo-allemande” au XX siècle. Identités, mémoires et histoire
No full textInternational audienceRetracer l’histoire de l’expression « symbiose judéo-allemande » impose d’analyser les débats auxquels elle a donné lieu à partir des années 1960 et la manière dont elle s’est progressivement imposée dans les discours sur l’histoire, la culture et l’identité des Juifs d’Allemagne
« Les ambiguïtés énonciatives dans le roman feel good : de l’invitation à l’identification à l’injonctionau bonheur. L’exemple de 'Ta deuxième vie commence quand tu comprends que tu n'en as qu'une' de Raphaëlle Giordano »
No full textInternational audienceÀ travers l’exemple de 'Ta deuxième vie commence quand tu comprends que tun’en as qu’une' (2015) de Raphaëlle Giordano, on se propose d’interrogerla présence récurrente d’ambiguïtés énonciatives dans les romans feel good.On en décrit les diverses manifestations stylistiques, entre énonciationimpliquée et énonciation distanciée, pour en analyser les effets pragmatiques,de l’identification facilitée du lecteur à son adhésion forcée à une certaineidée du bonheur, et questionner ainsi un trouble générique, quand le romandevient manuel de développement personnel

Le méga-projet de nouvelle capitale administrative au Caire : symbole du désir d’émergence africain
No full textInternational audienceEgypt has launched a project of enormous proportions with its construction of a new administrative capital (NAC) to the east of Cairo. The programme, which is well underway, is seen as a showcase for the power and modernity claimed by the Egyptian president, Field Marshal el-Sisi. Among its driving forces are education and sport, yet there remain the health and environmental risks that go hand-in-hand with such a gigantic project.L’Égypte s’est lancée dans un projet pharaonique avec la construction de la Nouvelle capitale administrative (NCA) à l’est du Caire. Ce programme, largement engagé, est pensé comme la ville vitrine du pouvoir et de la modernité revendiquée par le président égyptien, le maréchal al-Sissi. L’éducation et le sport en sont deux locomotives, avec cependant des risques sanitaires et environnementaux tous liés au gigantisme
An Open-source Implementation and Security Analysis of Triad’s TEE Trusted Time Protocol
No full textInternational audienceThe logic of many protocols relies on time measurements. However, in Trusted Execution Environments (TEEs) like Intel SGX, the time source is outside the Trusted Computing Base: a malicious system hosting the TEE can manipulate that TEE’s notion of time, e.g., jumping in time or affecting the perceived time speed. Previous work like Triad propose protocols for TEEs to maintain a trustworthy time source. However, in this paper, based on a public implementation of Triad that we contribute, we empirically showcase vulnerabilities to this protocol. For example, an attacker controlling the operating system, and consequently the scheduling algorithm, may arbitrarily manipulate their local TEE’s clock speed. What is worse, in case of faster malicious clock speeds, an attacker on a single compromised machine may propagate the attack to honest machines participating in Triad’s Trusted Time protocol, causing them to skip to timestamps arbitrarily far in the future. Then, infected honest machines propagate time-skips themselves to other honest machines interacting with them. We discuss protocol changes to Triad for higher resilience against such attacks
Acoustic context and dynamics of nonlinear phenomena in mammalian calls: the case of puppy whines
No full textInternational audienceNonlinear phenomena (NLP) are often associated with high arousal and function to grab attention and/or signal urgency in vocalizations such as distress calls. Although biomechanical models and in vivo / ex vivo experiments suggest that their occurrence reflects the destabilization of vocal fold vibration under intense subglottal pressure and muscle tension, comprehensive descriptions of the dynamics of NLP occurrence in natural vocal signals are critically lacking. Here, to plug this gap, we report the timing, type, extent and acoustic context of NLP in 12 011 whines produced by Beagle puppies ( Canis familiaris ) during a brief separation from their mothers. Within bouts of whines, we show that both the proportion of time vocalizing and the number of whines containing NLP, especially those with chaos, increase with time since separation, presumably reflecting heightened arousal. Within whines, we show that NLP are typically produced during the first half of the call, following the steepest rises in pitch (fundamental frequency, f o ) and amplitude. While our study reinforces the notion that NLP arise in calls due to instabilities in vocal production during high arousal, it also provides novel and efficient analytical tools for quantifying nonlinear acoustics in ecologically relevant mammal vocal communication contexts. This article is part of the theme issue ‘Nonlinear phenomena in vertebrate vocalizations: mechanisms and communicative functions’
