L'incesto della parola. Lingua e scrittura in Silvana Grasso

2009

Marina Castiglione in questo saggio – il primo interamente dedicato a Silvana Grasso, importante voce della letteratura contemporanea – mette in luce come i romanzi dell’autrice siciliana si presentino mutuamente intellegibili alla luce di un materiale linguistico e stilistico (oltre che tematico) che rimbalza dall’uno all’altro anche a notevoli distanze temporali. L’esposizione consente di far emergere, ai diversi livelli della scrittura, costanti, modifiche e variabili che danno all’intero corpus unitarietà nelle intenzioni e una assoluta inscindibilità tra lingua e fabula. Lingua e identità sono, infatti, una bussola certa nell’orizzonte frastagliato delle realtà rappresentate. Il ricors…

Ruolo delle metodologie analitiche sperimentali nella conoscenza dell’architettura storica. Il caso di Santa Maria dei Miracoli a Palermo

2010

Il contributo vuole mettere in evidenza il valore dei metodi di analisi sperimentale che supportano la conoscenza dell'architettura storica e sono efficaci in termini di ricadute nella progettazione e nella direzione dei lavori di restauro. The poster aims to highlight the value of the analysis methods that support the experimental knowledge of historic architecture and are effective in terms of impact in the design and direction of the restoration work.

CAD-R. Cuestionario de afrontamiento al dolor crónico: análisis factorial confirmatorio. ¿Hay diferencias individuales en sexo, edad y tipo de dolor?

2017

espanolRESUMEN Introduccion: Se presenta una revision del CAD-R (Cuestionario de afrontamiento al dolor reducido) (1) en una muestra de 4.389 pacientes diagnosticados con dolor cronico derivada de un estudio multicentrico de toda Espana (2). Material y metodo: Se analiza la estructura factorial mediante analisis factorial exploratorio (AFE) y confirmatorio (AFC), asi como la fiabilidad (consistencia interna y test retest a los tres meses, esta ultima sobre 2.825 pacientes). Se ponen a prueba cuatro modelos constatando que las estrategias de primer orden correlacionadas son las que aportan mejores indices de ajuste. Resultados: Tanto los indices de consistencia interna como los test-retest r…

Room acoustical parameters: A factor analysis approach

2009

Abstract In this study, we determined the most representative acoustical parameters for halls intended for verbal or music audition. Our study was carried out in nine halls of different shapes and designed for different uses. We measured the impulse response at a great number of points (many more than the minimum required by the ISO 3382 norm). From a physical viewpoint, all halls are enclosed three-dimensional areas. Our work hypothesis is that objective (measurable) acoustical parameters, or a combination of such parameters, must provide the acoustical information specific to each hall and must make it possible to grade each hall. Factor analysis was used to obtain these grading parameter…

Some perturbation results through localized SVEP

2016

Some classical perturbation results on Fredholm theory are proved and extended by using the stability of the localized single-valued extension property under Riesz commuting perturbations. In the last part, we give some results concerning the stability of property (gR) and property (gb.

Closure properties for integral problems driven by regulated functions via convergence results

2018

Abstract In this paper we give necessary and sufficient conditions for the convergence of Kurzweil–Stieltjes integrals with respect to regulated functions, using the notion of asymptotical equiintegrability. One thus generalizes several well-known convergence theorems. As applications, we provide existence and closure results for integral problems driven by regulated functions, both in single- and set-valued cases. In the particular setting of bounded variation functions driving the equations, we get features of the solution set of measure integrals problems.

Wulff shape characterizations in overdetermined anisotropic elliptic problems

2017

We study some overdetermined problems for possibly anisotropic degenerate elliptic PDEs, including the well-known Serrin's overdetermined problem, and we prove the corresponding Wulff shape characterizations by using some integral identities and just one pointwise inequality. Our techniques provide a somehow unified approach to this variety of problems.

Best approximation and variational inequality problems involving a simulation function

2016

We prove the existence of a g-best proximity point for a pair of mappings, by using suitable hypotheses on a metric space. Moreover, we establish some convergence results for a variational inequality problem, by using the variational characterization of metric projections in a real Hilbert space. Our results are applicable to classical problems of optimization theory.
