    Qu’il s’agisse de notre vie professionnelle ou de notre vie personnelle, la promesse d’immortalitĂ© exerce le mĂȘme pouvoir de sĂ©duction. La promesse de salut dĂ©livrĂ©e Ă  l’entreprise ne diffĂšre guĂšre de la promesse faite aux ĂȘtres humains. Cet idĂ©al de salut, qui a exercĂ© sa fascination sur toutes les Ă©poques, les religions ont promis de le rĂ©aliser. Les entreprises de conseil s’inscrivent dans la mĂȘme logique, dans la mesure oĂč elles constituent, pour les entreprises, l’équivalent contemporain d’une expĂ©rience religieuse. Les prophĂštes du conseil s’emploient Ă  gĂ©nĂ©rer ce genre de sentiments en utilisant tout un vocabulaire symbolique tel que « reconfiguration des processus », « meilleures pratiques », etc, dans un rituel baptisĂ© MĂ©taCapitalisme, impliquant une communautĂ© de croyants, en l’occurrence leurs clients. Ce rituel, par le biais du Culte du conseil, a des consĂ©quences qui vont bien au-delĂ  des seules entreprises clientes et affectent de maniĂšre importante de nombreux groupes de personnes et d’institutions dans notre sociĂ©tĂ© devenue globale. Ce constat justifie de procĂ©der Ă  un examen critique de ses mĂ©rites. Notre recherche explore la performance du MĂ©taCapitalisme, un terme forgĂ© par le gĂ©ant du conseil, Price Waterhouse Coopers (PWC), pour dĂ©crire sa vision de la « nouvelle Ă©conomie », qui traite de l’utilisation des e-markets, des Ă©changes en ligne et des communautĂ©s d’affaires en rĂ©seau, et a eu pour effet de dĂ©multiplier l’impact des dĂ©veloppements technologiques et des principales amĂ©liorations de la vie des affaires issues des annĂ©es 1990. Le MĂ©taCapitalisme peut ĂȘtre apprĂ©hendĂ© en analysant la conversion des leaders du MĂ©taCapitalisme au modĂšle prĂŽnĂ©. Notre Ă©tude, en appliquant des techniques de rĂ©gression Ă  un certain nombre d’indicateurs clĂ©s, identifie les tendances relatives Ă  la performance de ces leaders et les compare avec les tendances observĂ©es pour les 100 premiĂšres entreprises du groupe Fortune. Il en ressort que les entreprises du MĂ©taCapitalisme ont Ă©tĂ© incapables de maintenir la transformation apparemment brillante qu’elles avaient opĂ©rĂ©e en 1999 et que sur de nombreux points, les tendances prĂ©sentent des retournements imprĂ©vus par rapport au maintien de la structure idĂ©ale du MĂ©taCapitalisme. Une Ă©valuation critique de ces observations est effectuĂ©e de maniĂšre Ă  valider la possibilitĂ© de gĂ©nĂ©ralisation du modĂšle, afin d’ĂȘtre en mesure d’éviter une expĂ©rimentation sociale continue et prĂ©judiciable. En conclusion, la stratĂ©gie du MĂ©taCapitalisme prĂ©sente d’indĂ©niables similitudes avec les cultes religieux, ce qui amĂšne Ă  la question suivante : le MĂ©taCapitalisme aura-t-il le mĂȘme destin que la plupart de ces cultes, Ă  savoir, le dĂ©senchantement est liĂ© Ă  des espĂ©rances déçues ?

    Extremal Events in a Bank Operational Losses

    Operational losses are true dangers for banks since their maximal values to signal default are difficult to predict. This risky situation is unlike default risk whose maximum values are limited by the amount of credit granted. For example, our data from a very large US bank show that this bank could suffer, on average, more than four major losses a year. This bank had seven losses exceeding hundreds of millions of dollars over its 52 documented losses of more than 1millionduringthe1994−2004period.Thetailofthelossdistribution(aParetodistributionwithoutexpectationwhosecharacteristicexponentis0.95???1)showsthatthisbankcanfearextremeoperationallossesrangingfrom1 million during the 1994-2004 period. The tail of the loss distribution (a Pareto distribution without expectation whose characteristic exponent is 0.95 ? ? ? 1) shows that this bank can fear extreme operational losses ranging from 1 billion to 11billion,atprobabilitiessituatedrespectivelybetween111 billion, at probabilities situated respectively between 1% and 0.1%. The corresponding annual insurance premiums are evaluated to range between 350 M and close to $1 billion.Bank operational loss, value at risk, Pareto distribution, insurance premium, extremal event

    Galectins as New Prognostic Markers and Potential Therapeutic Targets for Advanced Prostate Cancers

    Get PDF
    A better understanding of multimolecular interactions involved in tumor dissemination is required to identify new effective therapies for advanced prostate cancer (PCa). Several groups investigated protein-glycan interactions as critical factors for crosstalk between prostate tumors and their microenvironment. This review both discusses whether the “galectin-signature” might serve as a reliable biomarker for the identification of patients with high risk of metastasis and assesses the galectin-glycan lattices as potential novel targets for anticancer therapies. The ultimate goal of this review is to convey how basic findings related to galectins could be in turn translated into clinical settings for patients with advanced PCa.Fil: Laderach, Diego Jose.

    Keyframe-based monocular SLAM: design, survey, and future directions

    Get PDF
    Extensive research in the field of monocular SLAM for the past fifteen years has yielded workable systems that found their way into various applications in robotics and augmented reality. Although filter-based monocular SLAM systems were common at some time, the more efficient keyframe-based solutions are becoming the de facto methodology for building a monocular SLAM system. The objective of this paper is threefold: first, the paper serves as a guideline for people seeking to design their own monocular SLAM according to specific environmental constraints. Second, it presents a survey that covers the various keyframe-based monocular SLAM systems in the literature, detailing the components of their implementation, and critically assessing the specific strategies made in each proposed solution. Third, the paper provides insight into the direction of future research in this field, to address the major limitations still facing monocular SLAM; namely, in the issues of illumination changes, initialization, highly dynamic motion, poorly textured scenes, repetitive textures, map maintenance, and failure recovery

    We prove the stability under integration and under Fourier transform of a concrete class of functions containing all globally subanalytic functions and their complex exponentials. This paper extends the investigation started in [J.-M. Lion, J.-P. Rolin: "Volumes, feuilles de Rolle de feuilletages analytiques et th\'eor\`eme de Wilkie" Ann. Fac. Sci. Toulouse Math. (6) 7 (1998), no. 1, 93-112] and [R. Cluckers, D. J. Miller: "Stability under integration of sums of products of real globally subanalytic functions and their logarithms" Duke Math. J. 156 (2011), no. 2, 311-348] to an enriched framework including oscillatory functions. It provides a new example of fruitful interaction between analysis and singularity theory.Comment: Final version. Accepted for publication in Duke Math. Journal. Changes in proofs: from Section 6 to the end, we now use the theory of continuously uniformly distributed modulo 1 functions that provides a uniform technical point of view in the proofs of limit statement

    Intermediate range order in (Fe,Al) silicate network glasses: a neutron diffraction and EPSR modeling investigation

    Get PDF
    The local structural environment and the spatial distribution of iron and aluminum ions in sodosilicate glasses with composition NaFexAl1-xSi2O6 (x = 1, 0.8, 0.5 and 0) is studied by high-resolution neutron diffraction combined with structural modeling using the Empirical Potential Structure Refinement (EPSR) code. This work gives evidence of differences in the structural behavior of Al3+ and Fe3+, which are both often considered to act as network formers in charge-balanced compositions. The short-range environment and the structural role of the two cations are not composition dependent, and hence the structure of intermediate glasses can then be seen as a mixture of the structures of the two end-members. All Al3+ is 4-coordinated for a distance d[4]Al3+-O=1.76±\pm0.01{\AA}. The high-resolution neutron data allows deciphering between two populations of Fe. The majority of Fe3+ is 4-coordinated (d[4]Fe3+-O=1.87±\pm0.01{\AA}) while the remaining Fe3+ and all Fe2+ (~12% of total Fe) are 5-coordinated (d[5]Fe-O=2.01±\pm0.01{\AA}). Both AlO4 and FeO4 are randomly distributed and connected with the silicate network in which they share corners with SiO4 tetrahedra, in agreement with a network-forming role of those species. On the contrary FeO5 tends to form clusters and to share edges with each other. 5-coordinated Fe is interpreted as network modifier and it turns out that, even if this coordination number is rare in crystals, it is more common in glasses in which they can have a key role on physical properties
