L'idéologie durable. Une analyse sémiotique du Rapport Brundtland

2017

Le rapport "Notre avenir à tous" (1989) exprime, en définissant le « développement durable », un souci d’harmonisation des rapports entre les nations qui était déjà présent dans la charte (1945) des nations unies prônant, de son côté, la paix internationale. Ce rapport marque pourtant un tournant stratégique: l’invitation à un mode de vie partagé passe cette fois par un « retour à la nature ». Il semble que la nature y acquière la valeur d’un impératif urgent, tout en faisant problème. En effet, en lisant le rapport, on s’aperçoit que cet appel à la nature est loin d’être univoque. Malgré ses apparences, la rien n’est plus instable que le concept de nature. L’analyse montre que le champ sém…

Model selection using limiting distributions of second-order blind source separation algorithms

2015

Signals, recorded over time, are often observed as mixtures of multiple source signals. To extract relevant information from such measurements one needs to determine the mixing coefficients. In case of weakly stationary time series with uncorrelated source signals, this separation can be achieved by jointly diagonalizing sample autocovariances at different lags, and several algorithms address this task. Often the mixing estimates contain close-to-zero entries and one wants to decide whether the corresponding source signals have a relevant impact on the observations or not. To address this question of model selection we consider the recently published second-order blind identification proced…

Identity Use and Misuse of Public Persona on Twitter

2016

Social media sites have appeared during the last 10 years and their use has exploded all over the world. Twitter is a microblogging service that has currently 320 million user profiles and over 100 million daily active users. Many celebrities and leading politicians have a verified profile on Twitter, including Justin Bieber, president Obama, and the Pope. In this paper we investigate the '‘hundreds of Putins and Obamas phenomenon’ on Twitter. We collected two data sets in 2015 containing 582 and 6477 profiles that are related to the G20 leaders’ profiles on Twitter. The number of namesakes varied from 5 to 1000 per leader. We analysed in detail various aspects of the Putin and Erdogan rela…

Towards enabling privacy preserving smart city apps

2016

Smart city applications are increasingly relying on personally identifiable data. A disclosure of such a data to a platform provider and possible 3rd parties represents a risk to the privacy of the application users. To mitigate the privacy risk, two-layer privacy-preserving platform architecture is introduced, wherein the personally identifiable information is dealt with at the inner layer (executed in a trusted environment), whereas only generic and personally unidentifiable information is made available to the apps at the outer layer of the architecture — e.g., in a form of app-specific events. The essential requirements for the platform are described, and the architectural implications …

Agentic perspective on fostering work-related learning

2017

Despite the increased recognition of the role that professional agency plays in work-related learning, little is known about what supports it. Based on current theoretical notions, the first purpose of this paper is to show that professional agency is closely intertwined with work-related learning. The second purpose is to introduce some main principles that promote professional agency and describe three work-related training settings that are aimed at fostering learning by taking into account agentic perspectives. These complementary settings include an identity coaching programme, a leadership coaching programme, and a work conference. Based on the qualitative meta-synthesis, the paper fu…

International artists-in-residence 1990-2010 : mobility, technology and identity in everyday art practices

2016

Considering the exponential growth of artistic residencies between 1990 and 2010 at an international level, artists working in associated mobility programmes have been challenged by unsettled transnational working practices and competition. This, in turn, provides them with the opportunity to develop their creative processes. It is shown that artists’-in-residence openness and willingness to travel internationally is, on the one hand, related to the development of information technology, and on the other, supported by travelling facilities, which have impact on lifelong learning and cultural maintenance. Whereas change of geographical environment is often associated to psychological and phy…
