The liver-specific vitellogenin B1 promoter is efficiently activated by estrogen within a nucleosomal environment after microinjection into Xenopus laevis oocytes, consistent with the hypothesis that significant nucleosome remodeling over this promoter is not a prerequisite for the activation by the estrogen receptor (ERalpha). This observation lead us to investigate determinants other than ERalpha of chromatin structure and transcriptional activation of the vitellogenin B1 promoter in this system and in vitro. We find that the liver-enriched transcription factor HNF3 has an important organizational role for chromatin structure as demonstrated by DNase I-hypersensitive site mapping. Both HNF3 and the estrogen receptor activate transcription synergistically and are able to interact with chromatin reconstituted in vitro with three positioned nucleosomes. We propose that HNF3 is the cellular determinant which establishes a promoter environment favorable to a rapid transcriptional activation by the estrogen receptor.

Nous développons la thèse selon laquelle la globalisation financière a conduit les États à transformer leur pratique de souveraineté, à adapter leur système de régulation et à redéfinir leur régime de citoyenneté non seulement afin de répondre aux contraintes de cette dynamique, mais aussi afin de poursuivre leurs propres objectifs politiques, définis en termes de quête de compétitivité. Dans ce contexte, la citoyenneté a évolué d'une relation (directe) entre autorités souveraines et citoyens, structurée autour d'un principe politique d'inclusion universelle, à une relation médiatisée par les marchés financiers, structurée autour d'un principe économique de compétitivité. Ce phénomène tend à être occulté par les approches en économie politique internationale (EPI) - réalisme, libéralisme, et structuralisme - qui n'intègrent pas le point de vue d'un acteur (le citoyen) qui sort du champ d'étude traditionnel de la discipline. Notre analyse entend ainsi contribuer à la réhabilitation du citoyen dans l'économie politique de la globalisation financière.

The discipline of Enterprise Architecture Management (EAM) deals with the alignment of business and information systems architectures. While EAM has long been regarded as a discipline for IT managers this book takes a different stance: It explains how top executives can use EAM for leveraging their strategic planning and controlling processes and how EAM can contribute to sustainable competitive advantage. Based on the analysis of best practices from eight leading European companies from various industries the book presents crucial elements of successful EAM. It outlines what executives need to do in terms of governance, processes, methodologies and culture in order to bring their management to the next level. Beyond this, the book points how EAM might develop in the next decade allowing today's managers to prepare for the future of architecture management.
