Apparati effimeri e arti decorative: carri di trionfo in corallo

2013

L’articolo illustra le profonde connessioni tra gli apparati effimeri con carri trionfali realizzati in occasione dei Festini di Santa Rosalia tra la fine del XVII e l’inizio del XVIII secolo a Palermo, disegnati dai famosi Architetti del Senato Paolo e Giacomo Amato, e la parallela produzione di superbi carri di trionfo in corallo. Vengono analizzate opere custodite non soltanto in musei e in collezioni private siciliane, ma anche nel resto d’Italia e all’estero, tutte opere di maestranze trapanesi. Viene inoltre segnalato e studiato un inedito trionfo di corallo di collezione privata di Palermo, raffigurante, sopra l’usuale carro, l’incontro tra la Madonna e Gesù Risorto.

Testing for public debt sustainability using a time-scale decomposition analysis

2013

In this paper we estimate the response of primary surplus to lagged debt to test for debt sustainability within the 17 EMU countries by using a factor model. The analysis is split into two stages. In the first stage we retrieve the cyclical and long-run components of primary surplus and debt ratios of each EMU country using a wavelet decomposition for each fiscal covariate, based on the Maximal Overlapping Discrete Wavelet Transform. In the second stage, we use Full Information Maximum Likelihood for a factor decomposition of thecross covariance matrix of the wavelet coefficients of primary deficit and debt to GDP ratios in order to measure the short run and the long run reaction of the pri…

La rappresentazione della Gloria monarchica attraverso l’effimero nei solenni funerali di Filippo V (1747) e di Carlo III di Borbone (1789) in Sicilia

2018

Nel 1747 e nel 1789 vennero sontuosamente organizzati a Palermo, capitale del Regno di Sicilia, i solenni funerali di Filippo V e di Carlo III del ramo dei Borbone di Spagna. La trasposizione di un’articolata impalcatura erudita e trionfalistica, organizzata nelle occasioni commemorative e diffusa attraverso la stampa, nella forma figurativa e sceno-tecnica degli apparati effimeri innalzati all’interno della cattedrale, appare tra gli aspetti più significativi di questi eventi luttuosi. Le riproduzioni degli allestimenti in onore dei due sovrani sono note attraverso le incisioni a corredo dei testi divulgativi. Questi grafici superstiti riflettono e spiegano le mutazioni estetiche del perio…

F17-like fimbriae from an invasive Escherichia coli strain producing cytotoxic necrotizing factor type 2 toxin

1994

The F17b fimbriae encoded by the transmissible virulence plasmid Vir, also coding for cytotoxic necrotizing factor type 2, were characterized. A 5.7-kb region of Vir mediates in vitro N-acetylglucosamine-sensitive adhesion to calf intestinal villi. Sequence analysis revealed that this region codes for a structural subunit and an adhesin closely related to the F17-A and F17-G proteins encoded by the F17 fimbrial gene cluster. The F17b-A gene presents an open reading frame of 540 bp encoding a polypeptide of 180 amino acids with a putative signal peptide of 21 residues. The mature protein shows an identity of 74% with the F17-A structural subunit. This 20-kDa protein is recognized by antiseru…

Importance sampling correction versus standard averages of reversible MCMCs in terms of the asymptotic variance

2017

We establish an ordering criterion for the asymptotic variances of two consistent Markov chain Monte Carlo (MCMC) estimators: an importance sampling (IS) estimator, based on an approximate reversible chain and subsequent IS weighting, and a standard MCMC estimator, based on an exact reversible chain. Essentially, we relax the criterion of the Peskun type covariance ordering by considering two different invariant probabilities, and obtain, in place of a strict ordering of asymptotic variances, a bound of the asymptotic variance of IS by that of the direct MCMC. Simple examples show that IS can have arbitrarily better or worse asymptotic variance than Metropolis-Hastings and delayed-acceptanc…

Stochastic ordering of classical discrete distributions

2010

For several pairs $(P,Q)$ of classical distributions on $\N_0$, we show that their stochastic ordering $P\leq_{st} Q$ can be characterized by their extreme tail ordering equivalent to $ P(\{k_\ast \})/Q(\{k_\ast\}) \le 1 \le \lim_{k\to k^\ast} P(\{k\})/Q(\{k\})$, with $k_\ast$ and $k^\ast$ denoting the minimum and the supremum of the support of $P+Q$, and with the limit to be read as $P(\{k^\ast\})/Q(\{k^\ast\})$ for $k^\ast$ finite. This includes in particular all pairs where $P$ and $Q$ are both binomial ($b_{n_1,p_1} \leq_{st} b_{n_2,p_2}$ if and only if $n_1\le n_2$ and $(1-p_1)^{n_1}\ge(1-p_2)^{n_2}$, or $p_1=0$), both negative binomial ($b^-_{r_1,p_1}\leq_{st} b^-_{r_2,p_2}$ if and on…

Hic situs Emmanuel, plangite Sicelides. Le esequie reali di Emanuele Filiberto di Savoia nella cattedrale di Palermo

2011

Lo studio prende le mosse dal ritrovamento presso la Biblioteca Nacional de España di una rara incisione seicentesca raffigurante le esequie solenni del giovane viceré Emanuele Filiberto di Savoia, celebrate a Palermo il 26 e 27 agosto del 1624 con la realizzazione di complessi apparati effimeri e la costruzione di un monumentale catafalco, per il quale si propongono adesso nuove ipotesi attributive. La stampa si rivela essere la più antica raffigurazione oggi nota dell'interno della cattedrale palermitana, acquisendo così un innegabile valore di testimonianza iconografica per lo studio e delle architetture effimere in ambiente ispanico e del tempio normanno nella sua perduta configurazione.

New Tents

2016

L’antropologia ha avuto un notevole impatto sulla cultura moderna specialmente nel rimarcare come le diversità culturali esistenti siano poco adeguate alla universalizzazione proposta dalla tecnologia. Lo spazio e la città, naturalmente, non fanno eccezione. La revisione dell’approccio ortodosso del Movimento Moderno operata dal Team X era basata su questo cambiamento culturale, epitomizzato dalle scoperte di Levi Strauss, un riferimento primario per quegli architetti. Naturalmente il contesto culturale era molto più ampio, in quanto comprendeva, fra l’altro, la sociologia, l’arte e l’esistenzialismo. Citiamo semplicemente le fondamentali teorie di Paul Ricoeur sui rischi della universalizz…

Examination of Escherichia coli from poultry for selected adhesin genes important in disease caused by mammalian pathogenic E. coli

2001

A collection of 1601 extraintestinal and intestinal Escherichia coli isolated from chickens, turkeys and ducks, in Belgium, France and Spain, was hybridised with gene probes specific for fimbrial and afimbrial adhesins (F17, F18, SSfa/F1C, Bfp, Afa, Cs31A, IntiminEae, Aida-1) of intestinal, urinary and invasive E. coli of mammals and with a probe specific for the P (Pap/Prs) fimbrial adhesin of urinary and invasive E. coli of mammals and birds. Three hundred and eighty-three strains (23.9%) were P-positive, 76 strains (4.8%) were Afa-positive, 75 strains (4.7%) were F17-positive, 67 strains (4.2%) were S-positive, 23 (1.4%) were Intimin-positive, and all were F18-, Cs31A-, Aida1- and Bfp-ne…

An extension of Guo's theorem via k--contractive retractions

2006

Abstract Let X be a infinite-dimensional Banach space. We generalize Guo's Theorem [D.J. Guo, Eigenvalues and eigenvectors of nonlinear operators, Chinese Ann. Math. 2 (1981) 65–80 [English]] to k- ψ -contractions and condensing mappings, under a condition which depends on the infimum k ψ of all k ⩾ 1 for which there exists a k- ψ -contractive retraction of the closed unit ball of the space X onto its boundary.
