Classical parameters of Shadowlands by Richard Attenborough (On C. S. Lewis's Life and Work)

The aim of this article is to show the classical parameters of Shadowlands by R. Attenborough, with a screenplay by W. Nicholson, on C. S. Lewis's life and work. Based upon an accurate reading of Lewis's works, the author of this article proposes to interpret the opposition Lewis / Gresham as the translation into the real life of the opposition between the Platonic or idealistic and the Aristotelian or materialistic temperaments which was already maintained by Coleridge. In any case, there are many classical references which must be taken into account in order to understand to what extent C. S. Lewis's Christianity is also a classic Christianity, that is, a Greek and Latin one.

Charged AdS black holes and catastrophic holography

We compute the properties of a class of charged black holes in antide Sitter space-time, in diverse dimensions. These black holes are solutions of consistent Einstein-Maxwell truncations of gauged supergravities, which are shown to arise from the inclusion of rotation in the transverse space. We uncover rich thermodynamic phase structures for these systems, which display classic critical phenomena, including structures isomorphic to the van der WaalsMaxwell liquid-gas system. In that case, the phases are controlled by the universal cusp and swallowtail shapes familiar from catastrophe theory. All of the thermodynamics is consistent with field theory interpretations via holography, where the dual field theories can sometimes be found on the world volumes of coincident rotating branes.

Extending the Kuznets Curve

[cat] Les darreres dècades s’han caracteritzat per un intens augment de les desigualtats salarials a nivell mundial. Aquest article allarga la hipòtesi clàssica de la Corba de Kuznets per cobrir les economies post-industrials i tractar d’explicar aquest fenomen. Segons la hipòtesi de la Corba de Kuznets Allargada, les desigualtats salarials podrien evolucionar segons una corba en forma d’N. La U-inverida d’aquesta corba seria deguda al procés de canvi estructural que acompanya a un procés de industrialització. I l’extrem dret de la mateixa, associada al creixement explosiu de la formació de capital humà en les economies modernes i post-industrials. En aquest sentit, els principals candidats per explicar el recent augment de les desigualtats: el canvi tècnic esbiaixat a favor del treball qualificat, la globalització (comerç i migracions) i els factors institucionals, estarien ja incorporats en l’evolució de la composició de la força de treball en termes de qualificacions. La limitada evidència empírica sobre aquest tema, tendeix a donar suport a la Corba de Kuznets Allargada.

Grau Mira, Ignacio: La organización del territorio en el área central de la 'Contestania' Ibérica, Anejo de la revista Lucentum, 12, Publicaciones de la Universidad de Alicante, Alacant, 2002

Els estudis sobre territoris iberics -no sobre arees territorials més o menys coherents, com l'estudi classic de Llobregat (1972) sobre la Contestania o el de Lillo (1981) sobre l'area murciana, que són una altra COsa- compten ja amb una tradició relativament llarga, des deis primers treballs de F. Burillo (1982) sobre la val! mitjana de l'Ebre i els d' A. Ruiz i M. Molinos (1984) al' Alt Guadalquivir, posteriorment els de J. Bernabeu, H. Bonet, P. Guerin i C. Mata a l'Edetania (en particular, Bonet, 1995) i els que diferents autors han realitzat a les arees costaneres de Catalunya (Martín i Plana, 2001). El trebal! d'Ignacio Grau Mira s'insereix plenament dins d'aquesta tradició i, com és lógic, se'n beneficia en gran mesura.

Auto- and allopolyploidy in Centaurea sect. Acrocentron s.l. (Asteraceae, Cardueae): karyotype and chromosome banding pattern analyses

Dysploidy and polyploidy are well documented in the large genus Centaurea, especially in sect. Acrocentron and in a small group of species from the Iberian Peninsula described as sect. Chamaecyanus, closely related to Acrocentron. We have explored two interesting cases of polyploid series in both sections: the polyploid series of Centaurea toletana in sect. Chamaecyanus and the series of C. ornata group in sect. Acrocentron. We have carried out a karyological study using both classic karyotype analyses and chromosome banding with fluorochromes.

A knowledge based signal processing approach to tonic identification in indian classical music

In this paper, we describe several techniques for detecting tonic pitch value in Indian classical music. In Indian music, the raga is the basic melodic framework and it is built on the tonic. Tonic detection is therefore fundamental for any melodic analysis in Indian classical music. This workexplores detection of tonic by processing the pitch histograms of Indian classic music. Processing of pitch histograms using group delay functions and its ability to amplify certain traits of Indian music in the pitch histogram, is discussed. Three different strategies to detect tonic, namely, the concert method, the template matching and segmented histogram method are proposed. The concert method exploits the fact that the tonic is constant over a piece/concert.templatematchingmethod and segmented histogrammethodsuse the properties: (i) the tonic is always present in the background, (ii) some notes are less inflected and dominant, to detect the tonic of individual pieces. All the three methods yield good results for Carnatic music (90−100% accuracy), while for Hindustanimusic, the templatemethod works best, provided the v¯adi samv¯adi notes for a given piece are known (85%).

Patriarchal Hauntings: Re-reading Villainy and Gender in Daphne du Maurier's Rebecca

Criticism of Daphne du Maurier’s popular classic Rebecca (1938) can be divided into two mainstream interpretations. On the one hand, it was traditionally marketed as a gothic romance where the hero and the heroine conquered the evil women that separated them. On the other, certain feminist critics have recently provided a very diff erent view of the story, aligning it with gothic narratives that deal with the dangers women suff er under the patriarchal control of their husbands. Th is would imply that du Maurier’s novel should not be read as a traditional romance that promotes patriarchy, as the former interpretation suggested. In this article, I propose, through a Gothic Studies and a Gender Studies reading, that villainy in this novel is not exclusively linked to gender and, therefore, the victim and abuser statuses cannot be equated to femininity and masculinity, respectively. Instead, I argue that villainy in the novel is inextricably connected to being in a powerful position within patriarchy, and that it is the desire to maintain this position and perpetuate the patriarchal system that leads the main characters (men and women) to commit acts of villainy.

El universo sonoro de la guitarra amplificada

L'univers sonor de la guitarra amplificada és la culminació d'un procés d'anys de recerca, experimentació i depuració de coneixements tècnics i teòrics sobre l'enorme paleta de possibilitats timbriques que ens ofereix la guitarra, ja sigui elèctrica, clàssica, acústica o flamenca. L'objectiu principal d'aquest treball és el d'atorgar al lector una gamma el més completa possible d'eines que li ajudin a comprendre les condicionants del so de l'instrument, per així ajudar‐ho en la cerca personal d'aquesta guitarra “perfecta” o en defecte d'això, per orientar‐ho per trobar i personalitzar la que més se li apropi.

Disseny i construcció d'un pèndol invertit

Aquest projecte consisteix en l’estudi del problema clàssic del pèndol invertit en l’àrea de control. Per tal de poder realitzar aquest estudi s’ha construït un prototip que simuli el comportament d’un pèndol invertit. Seguidament es dissenyen uns controladors PID i LQR per aquest prototip. Finalment s’escull el controlador LQR, que és per al qual es realitzen les simulacions i es programa el prototip real.
