Gouvernance d’entreprise et rémunération à l’aune de la nouvelle régulation financière américaine : big bang ou coup d’épée dans l’eau ?

Le rodéo à Wall Street a pris fin. En effet, le président américain a promulgué la réforme de la régulation financière le 21 juillet 2010. Le H.R. 4173 : Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 n’est toutefois que le début d’un long processus. La majeure partie de l’édifice législatif repose sur l’intervention d’agences gouvernementales chargées d’édicter des décrets d’exécution dans un délai plus ou moins long. L’adoption de la réforme américaine constitue néanmoins un signal fort à destination des acteurs de la finance pour leur signifier que les règles du jeu ont changé. L’objectif de ce papier d’actualisation s’attache à exposer les dispositions visant les sociétés commerciales et portant sur leur gouvernance et la rémunération de leurs dirigeants. Ces deux thématiques prennent, à l’heure actuelle, une résonance particulière avec la révélation d’émoluments aux montants exorbitants consentis dans des sociétés et des établissements financiers mis à mal par des erreurs stratégiques de leur management.

Work, personality and psychological distress : direct and moderating effects of the Big Five personality traits

L’objectif de ce mémoire est d’examiner les nombreuses associations qui existent entre les conditions de l’organisation du travail, les traits de personnalité et la détresse psychologique au travail. La question de recherche principale était : est-ce que les cinq grands traits de personnalité (Big Five personality traits) ont un effet modérateur sur la relation entre les conditions de l’organisation du travail et la détresse psychologique. De nombreuses autres questions ont aussi été considérées. Pour répondre aux vingt-et-une hypothèses proposées dans cette recherche, nous avons utilisé des données secondaires d’une étude transversale de 395 employés d’un service de police municipal. À la suite d’analyses multivariées, nous avons pu observer quatre associations significatives. Concernant les conditions de l’organisation du travail, nous avons trouvé que les demandes psychologiques en milieu de travail augment la détresse psychologique, tandis que le support d’un superviseur la diminue. En ce qui concerne, les traits de personnalité, nous avons trouvé qu’être névrotique (neuroticism) augmente la détresse psychologique. Finalement, nous avons trouvé un effet modérateur du trait de personnalité, être consciencieux (conscientiousness), sur la relation entre les demandes psychologiques et la détresse psychologique. Bref, nos résultats nous indiquent que les cinq grands traits de personnalité (Big Five personality traits) ont une influence mitigée sur la santé mentale en milieu de travail.

Some effects of asymmetries in a common pool natural resource oligopoly

Nous envisageons le cas d'une ressource naturelle renouvelable exploitée en commun par des firmes qui se concurrencent à la fois dans le marché du produit et dans l'exploitation de la ressource. Nous montrons que l'introduction de la moindre différence de coûts entre les firmes peut avoir un effet drastique sur la nature de l' équilibre, à comparer avec le cas de coûts identiques. Pour ce faire, nous prenons comme point de référence un équilibre de Nash markovien parfait qui existe dans le cas de firmes identiques et qui a la propriété que les firmes jouent une stratégie linéaire jusqu'à une borne supérieure endogène du stock et la stratégie correspondant à l' équilibre de Cournot statique au-delà de cette borne. Après avoir montré qu'un équilibre de cette nature n'est pas soutenable avec des coûts asymétriques, nous proposons une caractérisation complète d'un équilibre de Nash markovien parfait au jeu différentiel correspondant à ce cas.

Dynamics and Thermodynamics of the Arabian Sea Warm Pool

The present study examines the importance of low saline waters and resulting barrier layer in the dynamics of the ASWP using observational data.The oceanic general circulation models (OGCM) are very useful for exploring the processes responsible for the ASWP and their variability. The circulation and thermohaline structure stimulated by an OGCM changes a lot when the resolution is increased from mesoscale to macro scale. For a reasonable simulation of the ASWP, we must include the mesoscale turbulence in numerical models. Especially the SEAS is an eddy prominent region with a horizontal dimension of 100 to 500 km and vertical extent of hundred meters. These eddies may have an important role on the evolution of ASWP, which has not been explored so far.Most of the earlier studies in the SEAS showed that the heat buildup in the mixed layer during the pre-monsoon (March-May) is primarily driven by the surface heat flux through the ocean-atmosphere interface, while the 3-dimensional heat budget of the ML physical processes that are responsible for the formation of the ASWP are unknown. With this background the present thesis also examines the relative importance of mixed layer processes that lead to the formation of warm pool in the SEAS.

Del Big Bang a l'Homo Sapiens Sapiens. Una visió evolutiva global de la Història de l'Univers

Crec que un resum lleugerament informal pot animar al lector a endinsar-se en el seriós contingut del llibre. S'aixeca el teló (fa uns tretze mil set cents milions d'anys) amb un "chupinazo" que deixa en ridícul als dels "sanfermines". L' entropia comença a augmentar ... i ja no pararà! L'empat inicial entre la matèria i l' antimateria es decanta a favor de la matèria, encara que per molt poc! Matèria i antimatèria s'anihilen, però el lleuger excés de matèria fa que en l'anihilació en quedin suficients traces per a que la funció pugui continuar. Existeix un antimón d'antimatèria que transcorre en un antitemps i en el qual un antiCastells format de D-aminoàcids i L-carbohidrats ha escrit un antillibre? L'univers ja s'ha refredat suficientment per a que el deuteri pugui perviure un xic: via lliure a la formació de l'heli-4 (etapa còsmica). La matèria s'organitza ostensiblement: neix el Sistema de Períodes (etapa estel·lar). Els estels exploten i la pols formada embruta tot l'espai interestel·lar (etapa interestel·lar). Visita al "zoo molecular": molt carboni i molt enllaç triple. Espècies molt reactives que no reaccionen ... per no trobar amb què! El futbol, va també envair l'espai? En el tebi oceà, la matèria continua la seva escalada de la complexitat (etapa planetària). Apareix la vida: però, què és la vida? Fi de l'evolució determinista i començament de l'evolució contingent (etapa biològica). Justificada alarma entre els anaerobis: qui ha deixat escapar aquest gas (oxigen) tan verinós? El miracle de la vida en un univers hostil. L'arsenal d'armes preventives i defensives: vitamines C i E, catalasa, peroxidases, dismutases superoxídiques, etc. La meravella del transport electrònic. Com es possible tanta perfecció? L'escalada de la complexitat prossegueix acceleradament. Finalment, s'arriba a l'Homo sapiens sapiens: podria no ser com és? Millor canviar l'entorn que canviar l'Homo: l'evolució biològica s'ha acabat. Comença l'evolució cultural o social. La possible existència de vida i de vida intel·ligent extra-terrestres. La inevitable protagonisme de la Química dels derivats del carboni. El Principi antropo-cosmològic: realment, estem sols?

Characteristics of Arabian Sea mini warm pool and Indian summer monsoon

Arabian Sea Mini Warm Pool (ASMWP) is a part of the Indian Ocean Warm Pool and formed in the eastern Arabian Sea prior to the onset of the summer monsoon season. This warm pool attained its maximum intensity during the pre-monsoon season and dissipated with the commencement of summer monsoon. The main focus of the present work was on the triggering of the dissipation of this warm pool and its relation to the onset of summer monsoon over Kerala. This phenomenon was studied utilizing NCEP/NCAR (National Center for Environmental Prediction/National Center for Atmospheric and Research) re-analysis data, TRMM Micro wave Imager (TMI) and observational data. To define the ASMWP, sea surface temperature exceeding 30.25 C was taken as the criteria. The warm pool attained its maximum dimension and intensity nearly 2 weeks prior to the onset of summer monsoon over Kerala. Interestingly, the warm pool started its dissipation immediately after attaining its maximum core temperature. This information can be included in the present numerical models to enhance the prediction capability. It was also found that the extent and intensity of the ASMWP varied depending on the type of monsoon i.e., excess, normal, and deficient monsoon. Maximum core temperature and wide coverage of the warm pool observed during the excess monsoon years compared to normal and deficient monsoon years. The study also revealed a strong relationship between the salinity in the eastern Arabian Sea and the nature of the monsoon

Big Data: Wrongs and Rights by Andrew Cormack (WAIS Seminar)

Abstract: Big Data has been characterised as a great economic opportunity and a massive threat to privacy. Both may be correct: the same technology can indeed be used in ways that are highly beneficial and those that are ethically intolerable, maybe even simultaneously. Using examples of how Big Data might be used in education - normally referred to as "learning analytics" - the seminar will discuss possible ethical and legal frameworks for Big Data, and how these might guide the development of technologies, processes and policies that can deliver the benefits of Big Data without the nightmares. Speaker Biography: Andrew Cormack is Chief Regulatory Adviser, Jisc Technologies. He joined the company in 1999 as head of the JANET-CERT and EuroCERT incident response teams. In his current role he concentrates on the security, policy and regulatory issues around the network and services that Janet provides to its customer universities and colleges. Previously he worked for Cardiff University running web and email services, and for NERC's Shipboard Computer Group. He has degrees in Mathematics, Humanities and Law.

Big Data or Right Data?

Abstract Big data nowadays is a fashionable topic, independently of what people mean when they use this term. But being big is just a matter of volume, although there is no clear agreement in the size threshold. On the other hand, it is easy to capture large amounts of data using a brute force approach. So the real goal should not be big data but to ask ourselves, for a given problem, what is the right data and how much of it is needed. For some problems this would imply big data, but for the majority of the problems much less data will and is needed. In this talk we explore the trade-offs involved and the main problems that come with big data using the Web as case study: scalability, redundancy, bias, noise, spam, and privacy.

Hierarchical Prediction Machines and Big Data Analytics

An emerging consensus in cognitive science views the biological brain as a hierarchically-organized predictive processing system. This is a system in which higher-order regions are continuously attempting to predict the activity of lower-order regions at a variety of (increasingly abstract) spatial and temporal scales. The brain is thus revealed as a hierarchical prediction machine that is constantly engaged in the effort to predict the flow of information originating from the sensory surfaces. Such a view seems to afford a great deal of explanatory leverage when it comes to a broad swathe of seemingly disparate psychological phenomena (e.g., learning, memory, perception, action, emotion, planning, reason, imagination, and conscious experience). In the most positive case, the predictive processing story seems to provide our first glimpse at what a unified (computationally-tractable and neurobiological plausible) account of human psychology might look like. This obviously marks out one reason why such models should be the focus of current empirical and theoretical attention. Another reason, however, is rooted in the potential of such models to advance the current state-of-the-art in machine intelligence and machine learning. Interestingly, the vision of the brain as a hierarchical prediction machine is one that establishes contact with work that goes under the heading of 'deep learning'. Deep learning systems thus often attempt to make use of predictive processing schemes and (increasingly abstract) generative models as a means of supporting the analysis of large data sets. But are such computational systems sufficient (by themselves) to provide a route to general human-level analytic capabilities? I will argue that they are not and that closer attention to a broader range of forces and factors (many of which are not confined to the neural realm) may be required to understand what it is that gives human cognition its distinctive (and largely unique) flavour. The vision that emerges is one of 'homomimetic deep learning systems', systems that situate a hierarchically-organized predictive processing core within a larger nexus of developmental, behavioural, symbolic, technological and social influences. Relative to that vision, I suggest that we should see the Web as a form of 'cognitive ecology', one that is as much involved with the transformation of machine intelligence as it is with the progressive reshaping of our own cognitive capabilities.

Como el agua entre los dedos. Estudio de los impactos de un proyecto hidroeléctrico, y de las frágiles y débiles acciones colectivas en la defensa de un río: Caso Hidrosogamoso

La acción colectiva en el manejo y gobierno de los recursos de uso común (RUC) seguirá siendo uno de los asuntos que genera mayores controversias (especialmente cuando se trata de recursos naturales y procesos de gobernanza y gestión del agua), debido a los diversos enfoques que sobre el desarrollo se tienen. El presente estudio aborda el análisis de la acción colectiva en el manejo y gobierno de los recursos de uso común a partir del caso Hidrosogamoso en Santander. Además de ofrecer un análisis de los impactos ambientales, sociales y económicos, ventajas y efectos nocivos que puede tener un proyecto hidroeléctrico, se examinan algunos de los postulados básicos de la teoría de la acción colectiva y los RUC, con alguna alusión al enfoque de la bioeconomía. También se describe una de las experiencias comunitarias de autogobierno y preservación del río. Asimismo se estudia el contexto de interacción estratégica en la zona, en el conflicto entre quienes defienden el río y quienes abogan por el proyecto; se ubican las principales oportunidades políticas y aliados influyentes de los opositores durante la fase de construcción de la hidroeléctrica. Al final se insinúan posibles alternativas que podrían ayudar en la visibilización de las problemáticas generadas por el megaproyecto.
