Disegni per il restauro inutili: il caso dell’ultima sequenza di danni al complesso di villa Mondragone
No full textNella cultura della conservazione degli organismi architettonici storico-monumentali è da tempo ampiamente acquisita la consapevolezza della centrale importanza, per qualsiasi intervento che intenda porsi criteri di attendibilità storica e scientifica, dei grafici e delle conoscenze che il rilevamento consente di avere a disposizione. Il saggio illustra, con accenti polemici, la ricorrente inosservanza di tale principio nello specifico caso del Complesso di Villa Mondragone, significativa emergenza storica di proprietà – in parte – dell’Ateneo promotore della Collana. Negli interventi promossi negli ultimi tre decenni sulla Villa e sulle sue pertinenze, infatti, molto materiale disponibile – comprendente disegni di rilievo, saggi, documenti ed elaborati d’analisi – che avrebbe dovuto essere noto (poiché in parte anche pubblicato) a chi era chiamato a intervenire sul monumento, non è stato, invece, minimamente tenuto in considerazione, con dannose conseguenze talvolta anche irrimediabili
Vs of the uppermost crust structure of the Campi Flegrei caldera (southern Italy) from ambient noise Rayleigh wave analysis
No full textShear wave velocities (VS) are defined in the uppermost 1-2 km of the Campi Flegrei caldera through the non-linear inversion of the group velocity dispersion curves of fundamental-mode Rayleigh waves extracted from ambient noise cross-correlations between two receivers. Noise recordings, three months long, at 12 seismic stations are cross-correlated between all couples of stations. The experiment provided successful results along 54 paths (inter-stations distance), of which 27 sampled a depth greater than 1 km.
VS contour lines are drawn from 0.06 km b.s.l. to 1 km depth b.s.l. and show difference between the offshore (gulf of Pozzuoli and coastline) and the onshore areas. At 0.06 km b.s.l., the gulf of Pozzuoli and the coastline are characterized by VS of 0.3-0.5 km/s and of 0.5-0.7 km/s, respectively. Such velocities are typical of Neapolitan pyroclastic soils and fractured or altered tuffs. The inland shows VS in the range 0.7-0.9 km/s, typical of Neapolitan compact tuffs. Velocities increase with depth and, at 1 km depth b.s.l., velocities lower than 1.5 km/s are still present in the gulf and along the coastline while velocities higher than 1.9 km/s characterize the eastern sector (grossly coincident with the Neapolitan Yellow Tuff caldera rim), the S. Vito plain and the area between Solfatara and SW of Astroni.
Such features are much more evident along two cross-sections drawn in the offshore and onshore sectors by integrating our VS models with literature data. Our models join previous noise cross-correlation studies at greater scale at depths of 0.7-0.8 km, hence the picture of the Campi Flegrei caldera is shown up to a depth of 15 km. VS of about 1.7 km/s, corresponding to VP of about 3 km/s (computed by using the VP/VS ratio resulted in the inversion), are found at depths of 1.1 km, in the centre of the gulf of Pozzuoli, and at a depth of about 0.7 km b.s.l. onshore. An increment of VS velocity (~1.9-2.0 km/s) is locally observed onshore which might be attributed to a layer of tuffs and tuffites interbedded with thin lava beds, according to the correlation of VS with stratigraphies in the deep drillings of S.Vito

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The uppermost crust structure of Ischia (southern Italy) from ambient noise Rayleigh waves
No full textAmbient noise measurements were performed at the island of Ischia (southern Italy) along alignments of 2.4–
7 km by using two three-component seismic stations. Synchronous noise recordings of 2–20 h were crosscorrelated
over 20–30 s windows, stacked and iteratively band-pass filtered to enhance the dispersive wave
trains. Frequency time analysis was performed on the vertical and radial components of cross-correlations and
the fundamental-mode Rayleigh wave group velocity was obtained. Validation of the dispersion data was possible
with those obtained from an earthquake recording along a close path. The non-linear inversion of average
Rayleigh wave group velocity dispersion curves along 13 paths (receiver inter-distances) allowed the definition
of shear wave velocity models in the uppermost 1–2 km of the crust.
The correlation of VS profiles vs. depth and drilling stratigraphy allowed to attribute VS lower than 1 km/s to tuffs
and VS of 1.41km/s to very fractured lavas. Higher VS are found in the central area of the island, in correspondence
of the resurgent area. The top of the trachytic lava basement, with VS of 2.2–2.4 km/s and density of 2.3 g/cm3 is
about 0.6–0.7 km deep b.s.l. in the centre of Ischia, below altered, very fractured lava or thermally altered tuff
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
