This article aims, firstly, to question Facebook's power to orient action. This power is part of a regime of governmentality that operates on both economic and algorithmic levels and is exercised over diverse socio-economic players in the information and advertising market. This regime of digital governmentality coincides with a trend toward "media formatting" and with the rise of a marketing logic in the media space. Secondly, based on new analysis of data from two research projects on the use of news and media on the platform, we show how Facebook takes part in the "government of Internet users' (participative) conduct".
The last few years have seen the generalization of a communicative device which is technical and organizational integration of a terminal, an operating system, a network connection, an online platform to access applications (contents and services). Indeed, smartphones, connected TVs, tablet computers and game consoles are structured by this model which develops itself thanks to the rise of computer performance and capacity telecommunication networks. Single technical interface for users, they show, for industrial actors involved, a mode of organization cannot be reduced to a commercial intermediation. So at the heart of this configuration are the "platforms" which are a new form of goods and services distribution and carry out the renewal of uses and related practices and a change in the value chain which are in the depths of effective change, hopes and fears aroused by the devices presented in our contribution.Our paper aims at exposing the evolution of these devices in several fields of cultural industries especially mobile and audiovisual sectors with a focus on smartphone and connected TV industry. It intends thereby to question the double dialectic in these sectors in reconfiguration (integration / disintegration activities on the one hand and disintermediation / re-intermediation on the other hand).
-The acoustic ray method rests upon specular reflection, an intuition that gives access only to an approximation of the solution by not taking into account the parts of the field called diffusion and diffraction. In trying to understand rationally the roots of the approximation, it has appeared that the image source could be generalized and also that errors may be partially due to missing generalized sources, already in elementary geometries such as obtuse angles. Indeed, it is shown that the exact integral solution of a 2D acoustic problem, expressed as a series of terms, could be seen as the contribution of the different image sources, via a partial use of the Huygens' Principle. With the correspondence between the terms and the image sources shown, the missing sources would appear and the method would thereby be refined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
