Firm Size and Volatility Analysis in the Spanish Stock Market
2011
In this article, three strongly related questions are studied. First, volatility spillovers between large and small firms in the Spanish stock market are analyzed by using a conditional CAPM with an asymmetric multivariate GARCH-M covariance structure. Results show that there exist bidirectional volatility spillovers between both types of firms, especially after bad news. Second, the volatility feedback hypothesis explaining the volatility asymmetry feature is investigated. Results show significant evidence for this hypothesis. Finally, the study uncovers that conditional beta coefficient estimates within the used model are insensitive to sign and size asymmetries in the unexpected shock re…
Hallazgo de un denario merovingio inédito de Marsella en la ciudad de Tarragona (España)
2019
Documentamos el importante descubrimiento de un denario merovingio procedente de Masilia (Marsella) en la ciudad catalana de Tarragona (España). Debido a la escasez de esta tipología, no solamente en el suelo peninsular, creemos que su publicación es de una gran importancia. Y más aún considerando que el estudio de las relaciones comerciales tanto de corto como de largo recorrido entre el reino visigodo de Toledo y la Francia merovingia se mantiene poco desarrollado. We study the important fi nding of a Merovingian denarius from Masilia (Marseille) in the Catalan city of Tarragona (Spain). Due to the scarcity of this coinage, not only in the Iberian Peninsula, we believe that its publicatio…

Autor, realitat i ficció en la narrativa de Jordi Sarsanedas
2013
L’article analitza el tractament de la figura de l’autor real en els reculls de narracions de Jordi Sarsanedas. En el primer, «Mites», el prefaci auctorial ha estat interpretat en clau autobiogràfica, a pesar de l’absència de marques explícites, de la ficcionalització amb què s’hi elaboren alguns dels elements i de l’enunciació a càrrec d’un jo que es projecta fantasmagòricament en els narradors autodiegètics de les narracions de ficció. En el darrer, «Una discreta venjança», l’estatus del prefaci auctorial és ambigu perquè es confon amb la metaficcionalitat dominant en el recull, sobretot a causa de l’ús de la metalepsi de l’autor. També s’hi analitza el tractament de la figura de l’autor …

Experimental analysis of "bovedas tabicadas"
2012
A particular type of vaulted structures, known as bóvedas tabicadas (Catalan vaults), made with alternate layers of bricks and mortar and characterized by a very low thickness in comparison to the other two dimensions, are studied. The research has been faced under the historical aspect as well as under the mechanical one, developing experimental and numerical analysis regarding real existing structures. In particular, the experimental analysis, performed by effecting compression and bending tests on samples taken from a real structure, has been devoted to the constitutive material identification and the characterization is made by considering the material as an ideal homogeneous; further e…
La construcción de bóvedas en la Sicilia del siglo XIV: las capillas palatinas
2013
Il saggio analizza la variegata gamma di soluzioni tecniche e formali riscontrabili nella costruzione di volte reali nella Sicilia del XIV secolo, attraverso la casistica osservabile nelle cappelle platine. Dall'esame dei casi studio selezionati emerge un panorama ricco e vario, indicativo di un intreccio di esperienze e modelli di diversa provenienza, a confutare la tradizionale visione storiografica di un'isola totalmente chiusa in se stessa nel Trecento.
Los tesoros imperiales de Hispania
2020
Bajo un carácter exhaustivo, se ha planteado confeccionar el primer corpus hispano de tesoros, depósitos y/o conjuntos monetarios realizado hasta la fecha para la antigua Hispania imperial (abreviado como TIH). La cronología abarca desde el reinado de Augusto hasta el siglo VI d.C., coincidiendo con el final del periodo romano-visigodo. Se han recogido provisionalmente 413 conjuntos. No obstante, si se sumamos las fragmentarias noticias la cifra aumentaría a más de 810. En total, las monedas documentadas han ascendido a 138.384, aunque sin contar las noticias, que por su carácter son bastante dudosas. A tenor de los datos, la presente obra constituye el inventario más actualizado hasta la f…
Analysis of Relationship between Net Wage and Consumer Price Index
2013
Abstract In the present paper is presented an econometric analysis of the relationship between net salary and consumer price index. After a brief historical overview will be review the calculating statistics for selected variables and coefficients and will be presented the obtained values. We will study the relationship between variables. It will be realized the cloud of points and will be applied Fisher test. The intensity of selected variables will be study too and some forms of relationship between the two chose variables will be done. Student test is applied. It will be performed the parameter estimation for regression functions and Akaike's criterion will be applied. The homoscedastici…
Hétérogénéité spatiale : principes et méthodes
2004
Spatial Heterogeneity : Principles and Methods This article has a dual purpose . First , it describes the main econometric specifications which can be used to represent spatial heterogeneity , reflected in an instability of parameters in space and / or a heteroscedasticity of error terms . Only the specifications valid in cross-section are examined . Second , it explains the links between spatial heterogeneity and autocorrelation , the other major feature of localised data , defined by the absence of independence between geographical observations . In particular , we look at the extent to which traditional tests of heteroscedasticity or instability need to be amended to take account of spat…
