Volatility Weighting over Time in the Presence of Transaction Costs
2019
Numerous empirical studies demonstrate the superiority of dynamic strategies with a volatility-weighting-over-time mechanism. These strategies control the portfolio risk over time by adjusting the risk exposure according to updated volatility forecasts. Yet, to reap all the benefits promised by volatility weighting over time, the composition of the active portfolio must be revised rather frequently. Transaction costs represent a serious obstacle to benefiting from this dynamic risk control technique. In this article, we propose a modified volatility-weighting strategy that allows one to reduce dramatically the amount of trading costs. The empirical evidence shows that the advantages of the …
Dynamic response of multiply connected primary-secondary systems
1990
The nodal equations of motion of the composite system are given in «total» and «relative» coordinates. In the framework of the component-mode synthesis method a coordinate transformation, here defined as an admissible one, is used to reduce the nodal equations of motion. This coordinate transformation is theoretically and numerically compared with the coordinate transformation usually used in the literature, which generally gives larger errors with respect to the former when a reduced number of nodes is considered

‘My Language! Heavens!’: Strange Tongues and the Denial of Mimesis in The Tempest
2008
The Tempest est la dernière pièce « italienne » de Shakespeare. Cet article se penche sur quelques unes des conséquences poétiques et métaphysiques de la convention qui consiste à faire correspondre l’anglais de la pièce à l’italien que sont sensés parler les personnages. Nous montrerons que cette convention est un paramètre essentiel de l’action dramatique et qu’elle contribue à la mise en évidence du caractère fondamentalement « Autre » de la langue du théâtre. Dans The Tempest, l’imbrication d’une langue inconnue et d’une langue familière débouche par métonymie et par métaphore sur un déni du principe classique de mimesis.
On the sensitivity of bridge seismic response with local soil amplification
1998
The paper presents a numerical sensitivity study of the local site effects on structural response. Following a recently developed model of spatial coherency and a concept of a simple site coefficient the local site effects are modelled as filtrations of excitation processes with a frequency shift. An analysis of a bridge response with supports founded on different soils is carried out. The joint effects of dynamic response and pseudostatic motion are considered. Two types of response are analysed: longitudinal and transverse. The differences between dynamic displacements and force responses are pointed out.
Conductes de risc associades en jugadors patològics i professionals de pòquer i escacs
2016
espanolEl juego esta cada dia mas presente en la sociedad con prevalencias muy importantes, sobre todo, en jovenes y adolescentes. Como consecuencia, este estudio tiene como objetivo estudiar la relacion entre el juego patologico, el juego a nivel aficionado el juego profesional (ajedrez y poquer) en el control de impulsos y en el consumo de alcohol. Para ello, se ha utilizado una muestra compuesta por jugadores aficionados y profesionales de ajedrez y poquer, un grupo de jugadores patologicos y un grupo control. Los instrumentos han medido conducta de riesgo de ingesta de alcohol, control de impulsos y los criterios diagnosticos de juego patologico. Los principales resultados han mostrado …
The Uprooting in the Narrative Language of Foreign Land by Jonathan Raban
2022
The language and narrative style of Jonathan Raban, a contemporary English writer author of the novel Foreign Land (1985), seem to find in the themes of uprooting and self-searching a metaphorical and existential interpretation that in the search for identity alternates the desire to return to the origins, recovering lost affections and beloved places, with the attraction to the unknown. In this oscillation, masterfully rendered by the metaphorical and figurative language of the novel, Raban tells the awareness that the return to the origins is not always a point of arrival but a further turning point in life. The article focuses on some particularly effective linguistic and semantic aspect…
