Fiat lux – Shedding new light on derivatives markets.

Not so long ago, we policymakers thought we knew just what challenges we were facing for Europe to better take advantage of globalisation through a more sustainable model: these were climate change and a rapidly ageing society. However, since 2007 we have also learnt that there was another area requiring a deep sustainability check: the financial system. What started in 2007 as a credit crisis in the US market for subprime mortgages turned into a full-blown global fi nancial crisis in 2008, following Lehman’s default and has taken us near to a sovereign debt crisis as countries face the fiscal consequences of financial instability, on top of large public indebtedness. This highlights the importance of the financial system for society as a whole and, therefore, the political imperative of mending it so that finance serves the real economy – not the other way around. We therefore need to put in place a new set of rules and principles ensuring a stable and sustainable financial system. Without this our whole economy will be impeded from prospering again and we will not be able to address the challenges outlined above.

Sources, fate, and pathways of Leeuwin Current water in the Indian Ocean and Great Australian Bight: A Lagrangian study in an eddy-resolving ocean model

The Leeuwin Current is the dominant circulation feature in the eastern Indian Ocean, transporting tropical and subtropical water southward. While it is known that the Leeuwin Current draws its water from a multitude of sources, existing Indian Ocean circulation schematics have never quantified the fluxes of tropical and subtropical source water flowing into the Leeuwin Current. This paper uses virtual Lagrangian particles to quantify the transport of these sources along the Leeuwin Current's mean pathway. Here the pathways and exchange of Leeuwin Current source waters across six coastally bound sectors on the south-west Australian coast are analyzed. This constitutes the first quantitative assessment of Leeuwin Current pathways within an offline, 50 year integration time, eddy-resolving global ocean model simulation. Along the Leeuwin Current's pathway, we find a mean poleward transport of 3.7 Sv in which the tropical sources account for 60-78% of the transport. While the net transport is small, we see large transports flowing in and out of all the offshore boundaries of the Leeuwin Current sectors. Along the Leeuwin Current's pathway, we find that water from the Indonesian Throughflow contributes 50-66% of the seasonal signal. By applying conditions on the routes particles take entering the Leeuwin Current, we find particles are more likely to travel offshore north of 30°S, while south of 30°S, particles are more likely to continue downstream. We find a 0.2 Sv pathway of water from the Leeuwin Current's source regions, flowing through the entire Leeuwin Current pathway into the Great Australian Bight

La voix qui présente

L’expression « voix qui présente » permet d’envisager les différentes façons dont les films de l’époque de la généralisation du cinéma parlant ont pu continuer la tradition du bonimenteur dans les années 1930. L’analyse de séquences spécifiques amène à découvrir les méthodes d’introduction orale dans les films de cette époque. En incipit des films français, on retrouve des « voix de compère » humoristiques, reprenant la tradition du music-hall, des « voix dramatiques » créant du suspense, des « voix pédagogiques », au ton doctoral, et des « voix chantantes » grâce à leur accent ou à la musique. En établissant sa typologie, l’auteur fait un lien entre les films du début des années 1930 et les spectacles de scène des années antérieures à la guerre de 1914, puisque, dans les deux cas, il semble que la voix de présentation aide le spectateur à « entrer » dans l’oeuvre.The expression “voice that presents” makes it possible to think about the various ways in which films of the period when talking cinema became widespread may have continued the tradition of the film lecturer into the 1930s. Analysis of film sequences helps us to discover the ways in which orality was introduced to films of this period. At the beginning of French films we find humorous “announcer voices” in the music hall tradition, “dramatic voices” to create suspense, “pedagogical voices” with a professorial air, and “singing voices” by virtue of their intonation or accompanying music. Setting out this typology enables the author to establish a connection between films from the early 1930s and stage entertainment from before the war of 1914; in both cases, it appears that the presenting voice helped viewers “enter into” the work

"Construire le son d'un succès populaire: l'exemple de Nikita"

actes du colloque de Lyon, en 2002: "Cinéma contemporain, état des lieux".How is it possible to create a film success thanks to the sound? Luc Besson, the director of the film Nikita (1990), gave orders to the sound team to make the film sound "american". Analyses of sequences and interview with sound engineers help to explain how Besson has created a box-affice success.Comment le son cinématographique permet-il de créer un succès populaire? L'efficacité du film d'action de Luc Besson, Nikita (1990), provient en partie des directives (minimalistes) données aux ingénieurs du son pendant la réalisation et la post-production du film. Des analyses de séquences et des entretiens avec l'équipe son du film permettent de comprendre comment cette production française s'est donnée des allures "américaines"

Depth dependence of westward-propagating North Atlantic features diagnosed from altimetry and a numerical 1/6° model

International audienceA 1/6° numerical simulation is used to investigate the vertical structure of westward propagation between 1993 and 2000 in the North Atlantic ocean. The realism of the simulated westward propagating signals, interpreted principally as the signature of first-mode baroclinic Rossby waves (RW), is first assessed by comparing the simulated amplitude and zonal phase speeds of Sea Level Anomalies (SLA) against TOPEX/Poseidon-ERS satellite altimeter data. Then, the (unobserved) subsurface signature of RW phase speeds is investigated from model outputs by means of the Radon Transform which was specifically adapted to focus on first-mode baroclinic RW. The analysis is performed on observed and simulated SLA and along 9 simulated isopycnal displacements spanning the 0-3250 m depth range. Simulated RW phase speeds agree well with their observed counterparts at the surface, although with a slight slow bias. Below the surface, the simulated phase speeds exhibit a systematic deceleration with increasing depth, by a factor that appears to vary geographically. Thus, while the reduction factor is about 15-18% on average at 3250 m over the region considered, it appears to be much weaker (about 5-8%) in the eddy-active Azores Current, where westward propagating structures might be more coherent in the vertical. In the context of linear theories, these results question the often-made normal mode assumption of many WKB-based theories that the phase speed is independent of depth. Alternatively, these results could also suggest that the vertical structure of westward propagating signals may significantly depend on their degree of nonlinearity, with the degree of vertical coherence possibly increasing with the degree of nonlinearity

Developing hypnotic analogues of clinical delusions : Mirrored-self misidentification

Introduction. Despite current research interest in delusional beliefs, there are no viable models for studying delusions in the laboratory. However, hypnosis offers a technique for creating transient delusions that are resistant to challenge. The aim of this study was to develop an hypnotic analogue of one important delusion, mirrored-self misidentification. Methods. Twelve high hypnotisable participants received an hypnotic suggestion to see either a stranger in the mirror, a mirror as a window, or a mirror as a window with a view to a stranger. Participants' deluded beliefs were challenged, and following hypnosis, Sheehan and McConkey's (1982) Experiential Analysis Technique was used to explore participants' phenomenological experience of the delusion. Results. The majority of participants did not recognise their reflection in the mirror, described the person in the mirror as having different physical characteristics to themselves, and maintained their delusion when challenged. Conclusions. The hypnotic suggestion created a credible, compelling delusion with features strikingly similar to clinical cases of mirrored-self misidentification. Our findings suggest that Factor 2 within Langdon and Coltheart's (2000) two-factor framework may involve a lowering of the criteria used to accept or reject delusional hypotheses.PostprintPeer reviewe

Tilted convective plumes in numerical experiments

International audienceThe dynamics of a single convective plume in an isothermal ocean is investigated by numerically inte- grating the three dimensional Boussinesq equations. Our study emphasizes on the important consequences of a non-vanishing angle between the axis of rotation and the buoyancy force (gravity). Experiments are performed for four different values of the angle corresponding to open-ocean convection at latitude: 90° N, 60° N, 45° N and 0° N. We show that the horizontal component of the rotation vector leads to qualitative and quantitative changes in the convective dynamics of a single plume. Plume structures are aligned along the axis of rota- tion rather than the direction of gravity (tilted convection), the vertical velocity of the plume is reduced, and the mixing is enhanced by the horizontal component of the rotation vector. These results suggest that in future parametrisations of ocean convection the effect of the horizontal component of the rotation vector should be included

Sexually Appealing Ads Effectiveness on Indonesian Customers

This study aims to analyze the perception of Indonesian customers toward sex appeals in advertising as well as to understand what people think of sexually content advertising. Moreover, it is intended to also examine the role of conviction both cognitive and affective in sculpturing consumer’s attitude. Data collection methods conducted by web based survey method using snowball sampling. The study included 319 Indonesian respondents of each age-category and multi-background demography. Result from quantitative analysis demonstrating that conviction has influence on customers’ attitude formation process. Advertising should not only be interesting, but must also be convincing, either in the context of cognitive or affective state. Sexually appealing advertisement might be interesting and effective in some countries that have more overt culture, whereas, it is probably ineffective for countries with different cultural backgrounds. Conviction in ads elicited when the ad is successfully developing belief in consumers’ mind, where it matched their personality descriptions and made them pay more attention to the ad.
