Le “verità” del racconto. Riflessioni epistemologiche sulla ricerca nei contesti di mafia
2019
Il saggio affronta alcune questioni metodologiche relative all’uso delle storie di vita e del racconto biografico in contesti di ricerca sulla criminalità organizzata mafiosa. Partendo dalle testimonianze di uomini e donne appartenenti al mondo di Cosa Nostra (raccolte in un ampio arco temporale), si sofferma su una complessa esperienza di studio: l’ascolto del racconto di vita di Gaspare Spatuzza, tra l’ottobre del 2012 e l’ottobre del 2013, in un carcere in località protetta. In questo scenario analitico, si colloca l’interrogativo su come posizionare il “discorso” sulle mafie all’interno di “spazi simbolici” nei quali si fonda l’epistemologia del racconto. Una narrazione che interroga (d…
La “giusta distanza”: questioni metodologiche e regole dell’interazione nel récit de vie di un collaboratore di giustizia
2020
Il saggio affronta alcune questioni metodologiche relative all’uso del racconto biografico dei collaboratori di giustizia. Partendo da diverse testimonianze raccolte tra uomini e donne appartenenti al mondo di Cosa Nostra, nel corso di un ampio arco temporale, il lavoro si sofferma su una lunga intervista con Gaspare Spatuzza realizzata in 9 incontri svoltisi, tra l’ottobre del 2012 e l’ottobre del 2013, in un carcere in località protetta. I diversi piani analitici in gioco, legati alla personalità del soggetto e alla peculiarità della sua narrazione, hanno reso il testo di analisi fluido e incandescente. L’incrociarsi della storia di Spatuzza con la mia biografia ha richiesto uno sforzo ul…
High-order regularization in lattice-Boltzmann equations
2017
A lattice-Boltzmann equation (LBE) is the discrete counterpart of a continuous kinetic model. It can be derived using a Hermite polynomial expansion for the velocity distribution function. Since LBEs are characterized by discrete, finite representations of the microscopic velocity space, the expansion must be truncated and the appropriate order of truncation depends on the hydrodynamic problem under investigation. Here we consider a particular truncation where the non-equilibrium distribution is expanded on a par with the equilibrium distribution, except that the diffusive parts of high-order nonequilibrium moments are filtered, i.e., only the corresponding advective parts are retained afte…
Le Officine Ducrot, un esempio di organizzazione del lavoro dell'industria palermitana tra il XIX e il XX secolo
2022
Le officine Ducrot sono un'importante testimonianza del fiorente passato imprenditoriale palermitano che ha avuto un ruolo centrale tra la fine dell'Ottocento e i primi del Novecento del secolo scorso per il carattere internazionale e innovativo di una attività, nata da un piccolo mobilificio, trasformata in pochi anni in un prestigioso atelier artigianale, fino a diventare una società di produzione industriale con una affermazione artistica e commerciale tale da ottenere la quotazione in Borsa. I motivi del grande successo sono numerosi: il sodalizio tra il proprietario, Vittorio Ducrot, e l'architetto Ernesto Basile; la produzione di raffinati e moderni arredi, caratterizzati da un mix tr…
Optimisation des requêtes de similarité dans les espaces métriques répondant aux besoins des usagers
2012
The complexity of data stored in large databases has increased at very fast paces. Hence, operations more elaborated than traditional queries are essential in order to extract all required information from the database. Therefore, the interest of the database community in similarity search has increased significantly. Two of the well-known types of similarity search are the Range (Rq) and the k-Nearest Neighbor (kNNq) queries, which, as any of the traditional ones, can be sped up by indexing structures of the Database Management System (DBMS). Another way of speeding up queries is to perform query optimization. In this process, metrics about data are collected and employed to adjust the par…
Removable sets for Sobolev spaces
1999
We study removable sets for the Sobolev space W1,p. We show that removability for sets lying in a hyperplane is essentially determined by their thickness measured in terms of a concept of p-porosity.
Uniform, Sobolev extension and quasiconformal circle domains
1991
This paper contributes to the theory of uniform domains and Sobolev extension domains. We present new features of these domains and exhibit numerous relations among them. We examine two types of Sobolev extension domains, demonstrate their equivalence for bounded domains and generalize known sufficient geometric conditions for them. We observe that in the plane essentially all of these domains possess the trait that there is a quasiconformal self-homeomorphism of the extended plane which maps a given domain conformally onto a circle domain. We establish a geometric condition enjoyed by these plane domains which characterizes them among all quasicircle domains having no large and no small bo…
Embedding of Sobolev Spaces into Lipschitz Spaces
1989
The main result of the paper is that if Ω is a bounded uniform domain in ℝn and p>n, then the Sobolev space Wl, p(Ω) embeds continously into Cα(Ω), α = 1 - n/p.
“Mega-Sports Events, Gentrification and Social Mobilization in Rio de Janeiro” - Experiences from Metrô Mangueira
2017
Master's thesis Development management UT503 - University of Agder 2017 In order to promote gentrification of the city of Rio de Janeiro, the Brazilian government and the municipality of Rio de Janeiro have actively used Mega-Sports Events (MSE) in urban planning. Examples are tax cuts and the legalization of various measures for large-scale urban programs, to prepare the city for hosting these prestigious events. Whilst trying to fulfil the obligations from MSEs, the host city denies its citizens access to democratic participation and thereby their right to the city. The promises made to the international sportive federations regarding upgraded infrastructure, sportive arenas, media covera…
Extending the semiotics of embodied interaction to blended spaces.
2015
In this paper, we develop a new way of understanding interactions in blended spaces. We do this by developing ideas about embodied semiotics and then apply these ideas to the analysis of interaction in mixed-reality blended spaces (where the physical world and digital world are blended deliberately to provide new forms of interaction). We discuss how blended spaces provide a new medium within which people have experiences. The semiotic analysis reveals how blended spaces are constructed across the physical and the digital, highlighting the ontology, topology, volatility, and agency present within them. It shows how people move between the physical and digital spaces through the objects and …
