Objectives The pre-return-to-work medical consultation during sick leave for low back pain (LBP) aims at assessing the worker's ability to resume working without risk for his/her health, and anticipating any difficulties inherent to returning to work and job retention. This article summarizes the good practices guidelines proposed by the French Society of Occupational Medicine (SFMT) and the French National Health Authority (HAS), and published in October 2013. Methods Good practices guidelines developed by a multidisciplinary and independent task force (24 experts) and peer review committee (50 experts) based on a literature review from 1990 to 2012, according to the HAS methodology. Results According to the labour regulations, workers can request a medical consultation with their occupational physician at any time. The pre-return-to-work consultation precedes the effective return-to-work and can be requested by the employee regardless of their sick leave duration. It must be scheduled early enough to: (i) deliver reassuring information regarding risks to the lower back and managing LBP; (ii) evaluate prognostic factors of chronicity and prolonged disability in relations to LBP and its physical, social and occupational consequences in order to implement the necessary conditions for returning to work; (iii) support and promote staying at work by taking into account all medical, social and occupational aspects of the situation and ensure proper coordination between the different actors. Conclusion A better understanding of the pre-return-to-work consultation would improve collaboration and coordination of actions to facilitate resuming work and job retention for patients with LBP [less ▲]

We present the development of a holographic interferometer based on dynamic hologram recording with photorefractive crystals of the sillenite family and which is adapted for the observation of MEMS. A compact portable system was already presented in the past and used in various metrology and nondestructive applications on large scattering objects. It was emphasized the great versatility of the instrument which allows high resolution measurements. Here we show the development and achievement of an optical module which can be easily interfaced on the basic instrument, allowing small specular objects observation. Results of deformation of electrically actuated MEMS are shown. [less ▲]

Les dispositifs participatifs, dans la vie réelle, sont souvent soit verrouillés soit déconnectés de la décision finale sur laquelle ils sont censés porter. Cela peut avoir des effets délétères sur les publics que ces dispositifs voulaient impliquer. Il n'est pas rare que l'on donne le label "participation" à des processus dont la nature est mieux décrite par d'autres concepts. En définitive, c'est probablement dans des dispositifs centrés sur les personnes, et non sur des prises de décisions politiques, que l'exercice participatif est le plus susceptible d'avoir un effet positif univoque.

In 2003, the Walloon region has installed a tradable green certificate mechanism to support the production of ‘green’ electricity. In this paper, we estimate that the total cost of the mechanism amounts to 1,871 billion € for the period 2003-2012, corresponding to a support of 107 €/MWh produced, with important differences between production technologies, the solar photovoltaic receiving up to 588 €/MWh. International comparisons indicate that the Walloon mechanism is particularly generous. We also show that the induced carbon savings are extremely costly with an implicit price of avoided CO2 of 425 € per ton. [less ▲]

Dans le présent article, nous présentons un parcours didactique visant à faire évoluer chez les élèves le concept de tangente, de leur connaissance antérieure de tangente à un cercle comme droite ne coupant la courbe qu’en un seul point jusqu’à une définition formalisée au sein d’un cours d’analyse. Nous montrons ainsi qu’une définition d’un objet mathématique n’est ni définitive, ni une simple description de l’objet. Le choix d’une définition au détriment d’une autre doit se faire à la lumière d’un projet plus global relatif à l’institution à laquelle elle appartient. [less ▲]

Despite the growing importance of longitudinal data in neuroimaging, the standard analysis methods make restrictive or unrealistic assumptions. For example, the widely used SPM software package assumes spatially homogeneous longitudinal correlations while the FSL software package assumes Compound Symmetry, the state of all equal variances and equal correlations. While some new methods have been recently pro- posed to more accurately account for such data, these methods can be difficult to specify and are based on iterative algorithms that are generally slow and failure- prone. In this thesis, we propose and investigate the use of the Sandwich Estimator method which first estimates the parameters of interest with a (non-iterative) Ordinary Least Square model and, second, estimates variances/covariances with the “so-called” Sandwich Estimator (SwE) which accounts for the within-subject covariance structure existing in longitudinal data. We introduce the SwE method in its classic form, and review existing and propose new adjustments to improve its behaviour, specifically in small samples. We compare the SwE method to other popular methods, isolating the combination of SwE adjustments that provides valid and powerful inferences. While this result provides p-values at each voxel, it does not provide spatial inferences, e.g. voxel- or cluster-wise family-wise error-corrected p-values. For this, we investigate the use of the non-parametric inference approach called Wild Bootstrap. We again identify the set of procedures and adjustments that provide valid inferences. Finally, in the third and fourth projects, we investigate two ideas to improve the statistical power of the SwE method, by using a shrinkage estimator or a covariance spatial smoothing, respectively. For all the projects, in order to assess the methods, we use intensive Monte Carlo simulations in settings important for longitudinal neuroimaging studies and, for the first two projects, we also illustrate the methods by analysing a highly unbalanced longitudinal dataset obtained from the Alzheimer’s Disease Neuroimaging Initiative.

This paper aims to compare the theory of diagram presented in Peirce’s philosophy of mathematics and the reflections on the work of art formulated by Henry Van Lier and René Thom. The Peircean Theory of diagram states that a diagram is a configuration characterized as a totality (form) that is necessary and at the same time dynamic and experimental. In his lectures about the relation between the local and the global in art (Apologie du logos, 1990), Thom traces a theory of forms that can be compared to the conception of diagram in Peirce’s semiotics. For Thom, beauty is the result of strategies of framing and of composing parts in a dynamic totality. Van Lier’s develops the idea of a perfect totality characterized by a syntax of traits that are at the right place and that couldn’t be organized in any other way, without which the work of art would have no efficacy. For my part, I explore these conceptions of a necessary totality in the arts (aesthetic necessity) and in mathematical diagrams (the demonstration through perceptual forms) in order to describe the differences and the similarities between the theories and the domains of application.

Le scribe Amennakhte, fils d’Ipuy, fut un personnage central de la communauté de Deir el-Médineh à la 20e dynastie : élevé au rang de Scribe de la Tombe en l’an 16 de Ramsès III, il occupa ce poste durant plus de trente années, jusqu’à sa mort sous le règne de Ramsès VI. Fait exceptionnel, ce lettré ne nous est pas seulement connu comme rédacteur de textes documentaires afférents à la gestion de l’Institution de la Tombe, mais également comme auteur d’une série de textes relevant de la sphère littéraire au sens large, allant de l’enseignement à la satire en passant par des hymnes et eulogies. Après avoir brièvement présenté l’environnement dans lequel vivait Amennakhte — dont on pense connaître à la fois l’habitation dans le village, la tombe et une hutte qu’il occupa dans la Vallée des Rois — nous axerons notre présentation sur la dimension paléographique du personnage et présenterons les difficultés rencontrées lorsque l’on entend suivre la main du scribe dans la documentation hiératique de la 20e dynastie. Ce sera l’occasion d’un parcours diachronique entre une variété de supports (graffiti incisés, dipinti, ostraca et papyri) et de genres textuels, qui nous permettra d’observer les variations de formes et de ductus potentiellement attribuables à un même scribe. En nous appuyant essentiellement sur le matériel du Museum de Turin et de l’Institut Français d’Archéologie Oriental du Caire, cet exposé sera donc l’occasion de présenter les derniers progrès réalisés dans l’identification des mains de scribes de la communauté de Deir el-Médineh.
