Grâce au travail de Cécile Colonna, conservateur au département des Monnaies, médailles et antiques, la collection des vases grecs du duc de Luynes est présentée au grand public, dans une exposition qui se tient à la Bibliothèque Nationale de France depuis le 29 octobre 2013. Ce catalogue a été publié à cette occasion. Cécile Colonna nous présente en quelques mots les éléments essentiels de la biographie du duc de Luynes : né dans une des plus grandes familles de France en 1802,il fait brièvement carrière dans un corps militaire avant d'occuper des fonctions politiques, au niveau local pour commencer, avant d'être élu député à la nouvelle assemblée constituante puis législative de la toute nouvelle Seconde République. Le coup d'État de décembre 1851 met fin à cette carrière politique. Son goût pour l'art lui vient principalement de la vie qu'il mène dans les maisons familiales ; les nombreux voyages qu'il effectue en Italie, en Grèce et en Méditerranée orientale vont l'aider à parfaire ses connaissances de l'Antiquité. Il fondera l'Instituto di Correspondenza Archeologica, premier institut consacré entièrement à la recherche archéologique. En 1825, il est nommé directeur adjoint au musée Charles X : il y est en charge du classement des collections égyptiennes et grecques. Le 24 décembre 1830, il sera élu membre libre à l'Académie des inscriptions et belles-lettres.

In this thesis we study the problem of road taxation. This problem consists in finding the toll on the roads belonging to the government or a private company in order to maximize the revenue. An optimal taxation policy consists in determining level of tolls low enough to favor the use of toll arcs, and high enough to get important revenues. Since there are twolevels of decision, the problem is formulated as a bilevel bilinear program. ; Doctorat en sciences, Orientation recherche opérationnelle ; info:eu-repo/semantics/nonPublished

Abstract. Over the last decade, many cliff erosion studies have focused on frequency-size statistics using inventories of sea cliff retreat sizes. By comparison, only a few paid attention to quantifying the spatial and temporal organisation of erosion scars over a cliff face. Yet, this spatial organisation carries essential information about the external processes and the environmental conditions that promote or initiate sea-cliff instabilities. In this article, we use summary statistics of spatial point process theory as a tool to examine the spatial and temporal pattern of a rockfall inventory recorded with repeated terrestrial laser scanning surveys at the chalk coastal cliff site of Mesnil-Val (Normandy, France). Results show that: (1) the spatial density of erosion scars is specifically conditioned alongshore by the distance to an engineered concrete groyne, with an exponential-like decreasing trend, and vertically focused both at wave breaker height and on strong lithological contrasts; (2) small erosion scars (10−3 to 10−2 m3) aggregate in clusters within a radius of 5 to 10 m, which suggests some sort of attraction or focused causative process, and disperse above this critical distance; (3) on the contrary, larger erosion scars (10−2 to 101 m3) tend to disperse above a radius of 1 to 5 m, possibly due to the spreading of successive failures across the cliff face; (4) large scars significantly occur albeit moderately, where previous large rockfalls have occurred during preceding winter; (5) this temporal trend is not apparent for small events. In conclusion, this study shows, with a worked example, how spatial point process summary statistics are a tool to test and quantify the significance of geomorphological observation organisation.

OBJECTIVES: To appraise European guidelines for acute otitis media (AOM) in children, including methodological quality, level of evidence (LoE), astrength of recommendations (SoR), and consideration of antibiotic stewardship. DESIGN: Systematic review of the literature. DATA SOURCES: Three-pronged search of (1) databases: Medline, Embase, Cochrane library, Guidelines International Network and Trip Medical Database; (2) websites of European national paediatric associations and (3) contact of European experts. Data were collected between January 2017 and February 2018. ELIGIBILITY CRITERIA: National guidelines of European countries for the clinical management of AOM in children aged <16 years. DATA EXTRACTION AND SYNTHESIS: Data were extracted using tables constructed by the research team. Guidelines were graded using AGREE II criteria. LoE and SoR were compared. Guidelines were assessed for principles of antibiotic stewardship. RESULTS: AOM guidelines were obtained from 17 or the 32 countries in the European Union or European Free Trade Area. The mean AGREE II score was ≤41% across most domains. Diagnosis of AOM was based on similar signs and symptoms. The most common indication for antibiotics was tympanic membrane perforation/otorrhoea (14/15; 93%). The majority (15/17; 88%) recommended a watchful waiting approach to antibiotics. Amoxicillin was the most common first-line antibiotic (14/17; 82%). Recommended treatment duration varied from 5 to 10 days. Seven countries advocated high-dose (75-90 mg/kg/day) and five low-dose (30-60 mg/kg/day) amoxicillin. Less than 60% of guidelines used a national or international scale system to rate level of evidence to support recommendations. Under half of the guidelines (7/17; 41%) referred to country-specific microbiological and antibiotic resistance data. CONCLUSIONS: Guidelines for managing AOM were similar across European countries. Guideline quality was mostly weak, and it often did not refer to country-specific antibiotic resistance patterns. Coordinating efforts to produce a core guideline which can then be adapted by each country may help improve overall quality and contribute to tackling antibiotic resistance.
