Art and Money
No full textThis paper investigates the impact of equity markets and top incomes on art prices. Using a long-term art market index that incorporates information on repeated sales since the eighteenth century, we demonstrate that both same-year and lagged equity market returns have a significant impact on the price level in the art market. Over a shorter time frame, we also find empirical evidence that an increase in income inequality may lead to higher prices for art, in line with the results of a numerical simulation analysis. Finally, the results of Johansen cointegration tests strongly suggest the existence of a long-term relation between top incomes and art prices.
Art and Money
No full textThis paper investigates the impact of equity markets and top incomes on art prices. Using a newly constructed art market index, we demonstrate that equity market returns have had a significant impact on the price level in the art market over the last two centuries. We also find empirical evidence that an increase in income inequality may lead to higher prices for art, in line with the results of a numerical simulation analysis. Finally, the results of Johansen cointegration tests strongly suggest the existence of a long-run relation between top incomes and art prices.Art market;Equities;Income inequality;Cointegration;Comovement
Tradução de uma disputa : Christophe versus Pétion em La tragédie du roi Christophe, de Aimé Césaire
No full textEsta contribuição propõe a tradução comentada da primeira cena da peça de teatro La Tragédie du roi Christophe (A tragédia do rei Christophe), de Aimé Césaire. O texto foi publicado pelo autor martinicano em 1963 e encenado a partir de 1964. A história aborda o embate histórico entre os dois líderes revolucionários haitianos, Alexandre Pétion (1770-1818) e Henry Christophe (1767-1820), após o estabelecimento da independência do Haiti, em 1804. O ex-escravizado Henry Christophe I, autoproclamado rei do Haiti em 1811, protagoniza, na peça, os impasses políticos decorrentes do processo de descolonização para a constituição de um novo estado haitiano livre e democrático. Optamos por traduzir a cena que anuncia e ilustra, na abertura do primeiro Ato, o caráter trágico que permeia o desenrolar dos eventos.This contribution proposes the commented translation of the first scene of the play La Tragédie du roi Christophe (The tragedy of King Christophe), by Aimé Césaire. The text was published by the Martinican author in 1963 and staged from 1964 onwards. The story addresses the historical clash between the two Haitian revolutionary leaders, Alexandre Pétion (1770-1818) and Henry Christophe (1767-1820), after the establishment of Haitian independence in 1804. The ex-enslaved Henry Christophe I, self-proclaimed King of Haiti in 1811, stars, in the play, political impasses resulting from the decolonization process, for the constitution of a new free and democratic Haitian state. We chose to translate the scene that announces and illustrates, in the opening of the first Act, the tragic character that permeates the unfolding of events

Der Verfasser schildert kurz die Geschichte des Kautschuks und erwänt die apotheker welche daran beteiligt sind. Er legt anschliessend die Geschichte der Gummisauger und der Milchflaschen dar, deren eine der meistgängisten die « Robert'sche Milchflasche » gewesen ist.Christopher Columbus, rubber, and rubber nipples.
The author quickly traces the history of rubber, making note of the pharmacists who therein played a role. He exhibits the history of rubber nipples and that of infant bottles, of which one of the most widely used was the « Robert Bottle. »Labeÿ Robert. Christophe Colomb, le caoutchouc et les tétines.

Christophe Defeuilley, L’Entrepreneur et le Prince. La création du service public de l’eau
No full textBehind Christophe Defeuilley’s poetic title lies a comparative historical analysis of the establishment of public drinking water services in London, New York, and Paris, the three most populous cities at the dawn of the 20th century. The author combines the lens of economics and a long-term perspective (from the 16th to the beginning of the 20th century) focused largely on private and public actors, to trace how water distribution systems evolved and crystalized into the form they still have ..
Validation de l'alignement du trajectographe à l'aide des électrons et recherche de particules à long temps de vie dans le canal électron-muon dans l'expérience CMS au LHC
No full textThe first part of my work concerns the development of an algorithm using CMS data to automatically detect the presence of particular deformations than can occur in the CMS tracker. The method takes advantage of the bias that such deformations induce in the measurement of electron impulsion. The reliability of the method has been proved using Monte-Carlo simulation. The algorithm was then used to certify that none of the considered deformations affected the data recorded in 2012.The second part of my work consists of a statistical analysis of the data recorded by CMS, in order to look for evidence of the presence of exotic long-lived particles. The latter could manifest themselves through their decay to an electron and a muon. Such an observation would provide a strong clue of the existence of new physics. In the absence of any observation statistically significant, a Bayesian method is used to interpret this result in term of constraints on a supersymmetric model (MSSM).La première partie de mon travail porte sur le développement d'un algorithme utilisant les données enregistrées par CMS afin de détecter la présence de déformations particulières susceptibles d'affecter le trajectographe de CMS. La méthode s’appuie sur le biais que ces déformations induisent dans la mesure de l'impulsion des électrons. Sa fiabilité a été prouvée par simulation Monte-Carlo. Elle a été utilisée pour la validation des données 2012. La seconde partie de mon travail consiste en une analyse statistique des données de collisions prises par le détecteur CMS en 2012, afin de mettre en évidence la présence de particules neutres et à long temps de vie se désintégrant en un électron et un muon. L'observation d'un tel processus constituerait une preuve de l'existence de nouvelle physique. En l'absence d'observation statistiquement significative, une méthode Bayesienne est utilisée pour interpréter ce résultat en terme de contraintes sur un modèle supersymétrique (MSSM)

CMS tracker alignment validation with electron tracks
No full textThe CMS tracker is the largest silicon detector ever built. Its purpose is the reconstruction of charged particles tracks, from a collection of hits in the different tracker layers. To take advantage of the good resolution provided by the silicon sensors, we need to know precisely the position of all the tracker modules. For this purpose, minimization algorithms are used to estimate possible misalignments of these modules. Nevertheless, some global deformations may exist that are almost invisibles to these classical methods. The presented tool is sensible to some of these Weak Modes deformations, and is used to detect the eventual presence of one of these misalignments in the tracker geometry. The principle of the tool is explained. The results on Monte Carlo events
reconstructed with a simulation of misaligned detector are shown. Finally, results on 2012 data are presented
