Characterization of rhenium oxide films and their application to liquid crystal cells

2009

Rhenium trioxide exhibits high electronic conductivity, while its open cubic crystal structure allows an appreciable hydrogen intercalation, generating disordered solid phases, with protonic conductivity. Rhenium oxide thin films have been obtained by thermal evaporation of ReO3 powders on different substrates, maintained at different temperatures, and also by reactive magnetron sputtering of a Re metallic target. A comparative investigation has been carried out on these films, by using micro-Raman spectroscopy and x-ray diffraction. Two basic types of solid phases appear to grow in the films: a red metallic HxReO3 compound, with distorted perovskite structures, like in the bulk material, a…

Conception de documents numériques : Parcours méthodologique

2009

There is a strong social demand for studies of digital document. Yet our models of society and education are struggling to integrate issues related to these types of documents. However, the subject is less than half a century old, and so it is hardly surprising that the writing and training practices are just being developed. Like the book, the digital document involves many different skills and techniques in its development. The list of jobs tends to grow steadily: ergonomists, referencing specialists, information architects, programmers, designers, integrators ... It is therefore difficult to have a global view on all this know-how and the related methodologies. This special edition seeks…

Un balance de la modernización autonómica y las relaciones intergubernamentales

2015

International audience; This article contains an overview of the modernization of the regional administrations since its inception until present. We distinguish roughly four modernizing cycles: the first is mainly identified with the search for legitimacy and survival of the regional administrations. The second is inspired by the New Public Management (NPM) and the emergence of a post-burocratic paradigm that enables the development of new methodologies. The third is characterized by the primacy of e-administration and quality policies applied to public services. Finally, the last cycle poses antagonistic tendencies, according to the outbreak of the current economic crisis.; En este artícul…

Définir la structure de navigation : quelques outils méthodologiques

2008

On peut distinguer deux niveaux de structuration des documents numériques. Ces deux niveaux correspondent aussi à deux niveaux de découpage de l'information. le niveau «macro» correspond au découpage de l'information d'un domaine en différentes unités d'informations (écrans). Le niveau inférieur, ou « micro » correspond au découpage de l'information en concept sur chaque écran. Par « macro structuration », on entend donc la structuration du document qui n'est pas forcément visible par l'utilisateur mais qui est perceptible lors des déplacements en son sein. L'objectif de cette structuration est de proposer une arborescence, qui corresponde à l'objet du document numérique. Deux principaux ob…

La stylistique sémiotique d’Umberto Eco

2012

International audience; La sémiotique est définie par Umberto Eco comme "forme supérieure de la stylistique" et "modèle de toute critique esthétique". Aux yeux du sémioticien, le style n'est pas réductible à la dimension lexicale et syntaxique du discours (objet de la stylistique entendue dans son acception restrictive) mais doit être entendue comme une stratégie discursive. Eco tend à identifier le concept d'auteur "modèle" avec celui de style défini de la sorte. Le sémioticien se propose ainsi de décrire et d'analyser la "machinerie du style". Il ne définit pas le discours comme un système d'écarts par rapport à la langue commune mais comme l'accomplissement de toutes les virtualités du l…

What contexts are favorable for the adoption of the contract teacher policy ?

2010

Education systems in Francophone African countries are undergoing major reforms, consequence of the international commitment to achieve Universal Primary Education (UPE) by 2015. Teachers' recruitment is among the most important reforms for at least two reasons: first, various researches presented it as necessary otherwise UPE will not be achieved; second, the alternative policy proposed is unpopular as new teachers are recruited with lower qualification, receive lower salaries and have a less secure job position. Yet, some governments have succeeded in changing their teacher recruitment scheme and others have not. Conditions allowing a government to make the reform are still uninvestigated…

Modèle d'explication de l'issue des réformes des politiques publiques en Afrique sub-saharienne : Illustration avec la politique des enseignants cont…

2010

African countries' political arena is witnessing major changes due to the involvement of new political actors in the public policy making process (donors, political parties, civil society). In the past, the formulation of policies was a reflection of the central authority's will. Nowadays, governments are confronted with more resistance when adopting reforms. This paper laborates a model that describes the policy process in African countries and shows how new actors can influence the designing of the reform to their advantage. The model predicts that government success or failure in designing a reform according to its will is a function of the adoption pattern chosen and the ability of the …

Changement climatique et suivi de la biodiversité marine côtière aux Iles Kerguelen

2018

Nearshore marine habitats of the French sub-Antarctic islands concentrate a rich and unique biodiversity that is currently facing climate change and its still not well-understood and multifaceted effects. Understanding the impact of these changes and predicting the potential response of ecosystems requires advanced knowledge of marine life and the achievement of uninterrupted and long-term observing programs. The Proteker program, no. 1044 of the French Polar Institute Paul-Émile Victor, has been developped in partnership with the National Nature Reserve of French Southern Territories in order to establish an observatory of coastal marine biodiversity in the Kerguelen Islands and evaluate t…
