Influence of site response and focal mechanism on the performance of peak ground motion prediction equations for the Greek region
No full textThe predictive performance of ground motion prediction equations relative to peak horizontal acceleration (PHA) defined for the Greek region were found not to benefit from the inclusion of terms accounting for site response. This can be in part due to an inadequacy of standard methods for site classification to evaluate the expected amount of PHA amplification. Indeed, the adoption of a new method to derive classification from the analysis of regression residuals seems able to improve the predictive performance in comparison to the use of conventional classification. However, this improvement is limited by an intrinsic drawback of classification criteria, i.e. the implicit assumption that amplification be a site-specific property not depending on event characteristics. Instead, for the study area and at least within the range of earthquake magnitude and distance investigated, the inclusion of focal mechanism among the explanatory variables of equations both for PHA and for peak horizontal velocity (PHV) does not improve the predictive performances independently on how fault styles are categorized

No full text“Reverse Theatrofilm”. Hamlet del Wooster Group (2007-2012)
No full textIl Wooster Group è, nel giudizio di numerosi critici, studiosi e appassionati di teatro contemporanei, probabilmente la più importante compagnia d’avanguardia attiva oggi negli Stati Uniti; e si è rivolta alla più classica delle tragedie shakespeariane per compiere un ulteriore passo in avanti nello sviluppo del suo caratteristico stile che Matthew Causey ha definito come una “danza con la tecnologia”. Lo spettacolo del Wooster Group è animato da un gesto generativo denso e interessante, e si appoggia tanto sul testo shakespeariano quanto sul film realizzato per una leggendaria produzione nella storia delle messe in scena recenti dell’Hamlet: quella che fu presentata a Broadway nel 1964 con la regia di John Gielgud e Richard Burton nella parte del protagonista. Il Wooster Group usa il film come una sorta di testo di riferimento e, proiettandolo a fianco dell’azione scenica degli attori, crea una interazione live con la traccia audiovisiva in una sorta di “sofisticata forma di karaoke”, come ha scritto nella sua recensione il critico del New York Times Ben Brantley.
Lo spettacolo costituisce un esempio emblematico della pratica sempre più diffusa di interazione tra tecnologie audiovisive e saperi incorporati nel teatro e, più in genere, nella cultura contemporanea. Apparentemente uno spettacolo iper-mediale a causa del raffinatissimo utilizzo delle più aggiornate tecnologie audiovisive, l’Hamlet del Wooster Group rappresenta al contrario una somma dimostrazione del “sapere incorporato” quale fonte non surrogabile dell’eccellenza artistica nel teatro e nelle arti performatiche.The paper aims to discuss the acclaimed Wooster Group’s production of Shakespeare’s Hamlet (2007-2013). Perhaps the most prominent avant-garde theatre company working in the United States today, the renowned New York based Wooster Group chose the classic Shakespearian tragedy in order to drive forward its tactical performance style as a “dance with technology” (M. Causey). Animated by a richly generative gesture, the performance relies on the very Hamlet text as well as on the film of Richard Burton’s 1964 Broadway production, directed by John Gielgud. The Wooster Group production placed the film on stage alongside, used it as a form of master text, and interacted live with it in a sort of “sophisticated form of karaoke” (B. Brantley).
It is my opinion that the Wooster Group’s Hamlet is a case in point referred to the interaction between embodiments and technologies in contemporary theatre and culture. What I will try to show is that, while seemingly a hyper-mediatized kind of performance (because of an elaborate exploitation of up-to-date audio-visual technologies and archival resources), the Wooster Group’s Hamlet foregrounds embodied knowledge and living skills (of memory and action) as the source of artistic value and excellence
Application of a time probabilistic approach to seismic landslide hazard estimates in Iran

No full textThe interrelation between the local site conditions and the severity of destruction during earthquakes has increased the necessity for more investigations on soil characterization in recent years. In residential areas, where active seismic methods are problematic for defining soil properties, passive seismic methods have attracted considerable attention due to their cost-effective and non-invasive features. Therefore, we have utilized 35 single-station ambient seismic noise recordings in the seismically vulnerable city of Babol, Iran, to evaluate the site response (including azimuthal variation and resonance frequency), estimate the seismic vulnerability index (Kg), and classify the soil based on the Vs30 of the region. To address the aim, we extract Rayleigh wave ellipticities from ambient seismic noise using their polarization features and employ them to define the azimuthal variations, resonance frequencies, and Kg values of the region. In each station, the ellipticity curve is inverted with the support of supplementary geotechnical information to obtain a shear velocity profile. The inversion results have good consistency with borehole and downhole test information. The study identifies a low resonance frequency of 0.9 Hz with a NE directivity for the majority of the city and a Vs30 range of 180 m/s to 350 m/s. Moreover, the seismic bedrock of Babol City is represented by a 3D Vs model at a depth of 60 m. Our results reveal that the city is vulnerable to seismic hazards due to the thick and low-velocity deposits responsible for high amplification affecting the study region, which combines with a high seismic vulnerability index, particularly in the southern part. This work has applications for future structural design, urban development, and seismic hazard reduction
