Pistes pour une mesure de la compétence numérique
La compĂ©tence numĂ©rique est rĂ©clamĂ©e aujourdâhui, tant pour les jeunes en formation que pour le citoyen. Si lâexercice dâune telle compĂ©tence peut ĂȘtre constatĂ© Ă diverses occasions, les questions de son dĂ©veloppement et de sa certification restent pendantes. Dans le cadre du projet visaTICE, des rĂ©ponses Ă ces questions sont apportĂ©es. La mise en place dâune certification y est un Ă©lĂ©ment majeur. Toutefois, il nâest pas le seul. Le problĂšme le plus important auquel il faut faire face est celui de la mise en place dâun dispositif souple qui sâappuie sur lâĂ©cole sans se soumettre Ă sa structure et Ă son organisation. Si les dĂ©veloppements actuels du projet ont permis de produire des rĂ©sultats tout Ă fait exploitables dans dâautres contextes, la preuve nâest pas encore faite, en termes de recherche, de lâefficacitĂ© du dispositif et de la pertinence de la certification. Les Ă©preuves de cette certification seront rĂ©alisĂ©es par un nombre significatif dâĂ©lĂšves en mai 2012. Pour lâinstant, seul le principe de co-construction de celle-ci constitue une garantie.Nowadays, in the educational field, digital literacy is considered absolutely necessary for students and citizens. If it is occasionally easy to observe the good practice of learners, there remains to determine how to train them and how to certify their abilities. The visaTICE project tries to face both issues. In this project, certification is a big challenge, but another challenge is to set up a system that takes into account the school context but that is not constrained by it. Presently the visaTICE project has developed online courses, tests, ability trees, coach training programs, which can be used in different contexts but we are not able to prove now, neither the training efficiencies, nor the suitability of the certification tests. A significant number of students will participate in the certification test for the first time in May 2012. Up to now, the collaborative design principle applied in visaTICE acts as a warranty

Neptunism and transformism:Robert Jameson and other evolutionary theorists in early nineteenth-century Scotland
This paper sheds new light on the prevalence of evolutionary ideas in Scotland in the early nineteenth century and establish what connections existed between the espousal of evolutionary theories and adherence to the directional history of the earth proposed by Abraham Gottlob Werner and his Scottish disciples. A possible connection between Wernerian geology and theories of the transmutation of species in Edinburgh in the period when Charles Darwin was a medical student in the city was suggested in an important 1991 paper by James Secord. This study aims to deepen our knowledge of this important episode in the history of evolutionary ideas and explore the relationship between these geological and evolutionary discourses. To do this it focuses on the circle of natural historians around Robert Jameson, Wernerian geologist and professor of natural history at the University of Edinburgh from 1804 to 1854. From the evidence gathered here there emerges a clear confirmation that the Wernerian model of geohistory facilitated the acceptance of evolutionary explanations of the history of life in early nineteenth-century Scotland. As Edinburgh was at this time the most important center of medical education in the English-speaking world, this almost certainly influenced the reception and development of evolutionary ideas in the decades that followed.</p
The James Webb Space Telescope Mission
Twenty-six years ago a small committee report, building on earlier studies,
expounded a compelling and poetic vision for the future of astronomy, calling
for an infrared-optimized space telescope with an aperture of at least .
With the support of their governments in the US, Europe, and Canada, 20,000
people realized that vision as the James Webb Space Telescope. A
generation of astronomers will celebrate their accomplishments for the life of
the mission, potentially as long as 20 years, and beyond. This report and the
scientific discoveries that follow are extended thank-you notes to the 20,000
team members. The telescope is working perfectly, with much better image
quality than expected. In this and accompanying papers, we give a brief
history, describe the observatory, outline its objectives and current observing
program, and discuss the inventions and people who made it possible. We cite
detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space

Carbone des sols en Afrique
Les sols sont une ressource essentielle Ă prĂ©server pour la production dâaliments, de fibres, de biomasse, pour la filtration de lâeau, la prĂ©servation de la biodiversitĂ© et le stockage du carbone. En tant que rĂ©servoirs de carbone, les sols sont par ailleurs appelĂ©s Ă jouer un rĂŽle primordial dans la lutte contre lâaugmentation de la concentration de gaz Ă effet de serre. Ils sont ainsi au centre des objectifs de dĂ©veloppement durable (ODD) des Nations unies, notamment les ODD 2 « Faim zĂ©ro », 13 « Lutte contre le changement climatique », 15 « Vie terrestre », 12 « Consommation et production responsables » ou encore 1 « Pas de pauvretĂ© ». Cet ouvrage prĂ©sente un Ă©tat des lieux des sols africains dans toute leur diversitĂ©, mais au-delĂ , il documente les capacitĂ©s de stockage de carbone selon les types de sols et leurs usages en Afrique. Il propose Ă©galement des recommandations autour de lâacquisition et de lâinterprĂ©tation des donnĂ©es, ainsi que des options pour prĂ©server, voire augmenter les stocks de carbone dans les sols. Tous les chercheurs et acteurs du dĂ©veloppement impliquĂ©s dans les recherches sur le rĂŽle du carbone des sols sont concernĂ©s par cette synthĂšse collective. Fruit dâune collaboration entre chercheurs africains et europĂ©ens, ce livre insiste sur la nĂ©cessitĂ© de prendre en compte la grande variĂ©tĂ© des contextes agricoles et forestiers africains pour amĂ©liorer nos connaissances sur les capacitĂ©s de stockage de carbone des sols et lutter contre le changement climatique
