The MetaCapitalism Cult.
Quâil sâagisse de notre vie professionnelle ou de notre vie personnelle, la promesse dâimmortalitĂ© exerce le mĂȘme pouvoir de sĂ©duction. La promesse de salut dĂ©livrĂ©e Ă lâentreprise 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 sâinscrivent dans la mĂȘme logique, dans la mesure oĂč elles constituent, pour les entreprises, lâĂ©quivalent contemporain dâune expĂ©rience religieuse. Les prophĂštes du conseil sâemploient 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 lâoccurrence 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 dâinstitutions 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 lâutilisation des e-markets, des Ă©changes en ligne et des communautĂ©s dâaffaires en rĂ©seau, et a eu pour effet de dĂ©multiplier lâimpact 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 dâindicateurs 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 quâelles 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 dâĂȘtre en mesure dâĂ©viter une expĂ©rimentation sociale continue et prĂ©judiciable. En conclusion, la stratĂ©gie du MĂ©taCapitalisme prĂ©sente dâindĂ©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 1 billion to 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
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 âgalectin-signatureâ 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
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
Integration of Oscillatory and Subanalytic Functions
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
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=1.760.01{\AA}. The high-resolution neutron data allows
deciphering between two populations of Fe. The majority of Fe3+ is
4-coordinated (d[4]Fe3+-O=1.870.01{\AA}) while the remaining Fe3+ and all
Fe2+ (~12% of total Fe) are 5-coordinated (d[5]Fe-O=2.010.01{\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
