Giuseppe Samonà e la “spina dorsale” di Gibellina Nuova

2020

Nel 1970 Giuseppe Samonà coordina il gruppo di progettazione formato da Vittorio Gregotti, Gianni Pirrone e Alberto Samonà per il Progetto del Centro civico, commerciale e culturale di Gibellina Nuova. Del piano è realizzato il municipio e poi, rielaborato e in altro luogo, il teatro. I monumenti, fondati su un asse pedonale in quota connesso a un suolo artificiale articolato, esprimono l’unità architettura – urbanistica e anticipano, per certi versi, una riflessione successiva del Direttore dello IUAV sulla dialettica fra urbano e rurale.

Settore ICAR/14 - Composizione Architettonica E UrbanaIn 1970 Giuseppe Samonà coordinated a design team (with Vittorio Gregotti Gianni Pirrone and Alberto Samonà) for the project of the Civic Commercial and Cultural Centre of Gibellina Nuova. From this plan among the monuments just the town hall was built. The theatre was proposed later for a different place. The buildings should have been linked to a pedestrian axial gangway connected to an articulated artificial ground. The complex should have shown the unity between architecture and urban planning anticipating in some ways a later Samona’s reflection about the dialectic between urban and rural.

Play and Self-Reflection. Eugen Fink’s Phenomenological Anthropology

2018

The paper takes into consideration the relationship between philosophical anthropology and phenomenology from the point of view provided by Eugen Fink’s philosophical path. Starting with phenomenological researches into the structure of constitution and reduction, after the Second World War Fink puts forth an anthropological theory based on the notion of play. This paper identifies the self-reflective and practical structure of Selbstbesinnung as a constant element of Fink’s analysis of the phenomenological method, of consciousness, and of the anthropological dimension of play, thus suggesting a profound continuity in his philosophical thought.

Rappresentazioni e territorio nelle dinamiche del turismo: il caso della Lonely Planet Sicily

2018

L’attuale dibattito sul riordino territoriale del Paese rende nuovamente centrale il concetto di territorio che, da sempre, in una prospettiva geografica pone problemi definitori. Esso può essere, infatti, oggetto di produzioni simboliche e (ri)semantizzazioni in grado di ridefinirlo e di creare specifiche modalità di interazione. A questo proposito, il presente lavoro intende proporre una riflessione su alcune dinamiche di produzione e riproduzione simbolica che interessano il concetto di territorio nel turismo, ambito in cui si può osservare una relazione diretta tra rappresentazione del territorio (intesa anche come narrazione) e possibilità d’azione. In particolare, attraverso il caso s…

Settore M-GGR/02 - Geografia Economico-PoliticaThe current debate about the Italian territorial reorganization makes again fundamental the concept of «territory». This paper aims to reflect on some important dynamics that concern the idea of territory. More in particular I explore in which form it can be (re)semantised through some tourism representations and narrations able to create specific ways of interaction. By taking into account the case study of the Lonely Planet 2017 digital tourist guidebook dedicated to Sicily that splits (and reorganizes) the island in smaller «regions» it is possible to reflect on a complex space dynamic able to redefine the same idea of territory. Indeed the tourist guidebook uses both texts and geographical maps to propose an anthology of homogeneous and coherent destinations to make the Otherness more accessible for the readers. This process demonstrates how symbolic (re)productions of a territory can give rise to specific constructions of places creating different concepts of region and therefore performative spaces and opportunities of «agency». In other terms the (re)definition of the Sicilian territory proposed by the guide invites tourists to consider a new (narrated) geography invites and invites to interact with it thinking as visitors. From a geographical and cultural point of view reflection on these dynamics allows us to consider some (re)definitions of space in relation to forms of textualization (even on the maps). An imaginary but performative geography that attributes to the concept of territory epistemological and gnoseological possibilities.Settore M-GGR/01 - Geografia

Toward a Phenomenology-oriented Transformative Education in Adult Life

2021

The paper highlights Husserlian phenomenology as a fruitful pedagogical paradigm for adult education philosophy. Actually, through a comparison with the Transformative Learning approach as developed by Jack Mezirow, phenomenology is presented as providing a peculiar account on learning from experience as well as on reflection. More precisely, a stress on the value of reflection in adulthood is detected both in the Deweyan line of thought, as expressed by Mezirow, and in the Husserlian one, as developed also in Martin Heidegger, Hannah Arendt, and Paul Ricoeur. My aim is to show that, even though the reflective approach has certainly affected contemporary education, chiefly the phenomenologi…

A crustal seismic profile across Sicily

2011

Abstract A crustal reflection seismic profile, more than 100 km long, was recorded across central Sicily, from the Tyrrhenian shore to the Sicily Channel, to understand the deep structures and the collision mechanisms between Europe and Africa and the subsequent geodynamic evolution. The profile was acquired using explosive sources and 240 active channels recorded by a Sercel 408-XL, 24 bits A/D converter, with a 12 km spread and a 24-fold coverage. The data were processed following a non-conventional procedure in order to preserve the relative amplitudes of the reflections and to better investigate the Sicily deep structures down to the Moho. The main highlighted structures are the dramati…

Boron doping of silicon rich carbides: Electrical properties

2013

Boron doped multilayers based on silicon carbide/silicon rich carbide, aimed at the formation of silicon nanodots for photovoltaic applications, are studied. X-ray diffraction confirms the formation of crystallized Si and 3C-SiC nanodomains. Fourier Transform Infrared spectroscopy indicates the occurrence of remarkable interdiffusion between adjacent layers. However, the investigated material retains memory of the initial dopant distribution. Electrical measurements suggest the presence of an unintentional dopant impurity in the intrinsic SiC matrix. The overall volume concentration of nanodots is determined by optical simulation and is shown not to contribute to lateral conduction. Remarka…

Nylon-Supported Plasmonic Assay Based on the Aggregation of Silver Nanoparticles: In Situ Determination of Hydrogen Sulfide-like Compounds in Breath …

2019

A procedure for supporting silver nanoparticles (AgNPs) on nylon is proposed. Besides, the membrane has been developed as a solid-phase colorimetric plasmonic sensor for volatile sulfide compounds (VSCs) like H2S, CH3SH, and (CH3)2S. AgNP behavior in the membrane has been studied by UV-vis diffuse reflectance spectrometry, Raman spectrometry, High-resolution transmission electron microscopy (HR-TEM), and Scanning electron microscopy (SEM). The sensor responded by changing its color from yellow in absence of VSCs to several orange/brown colors in the function of VSC concentration as occurs in solution; an increase in the hydrodynamic diameter, estimated by both asymmetrical flow field-flow f…

Isolated self-assembled InAs/InP(001) quantum wires obtained by controlling the growth front evolution

2007

6 páginas, 5 figuras. In this work we explore the first stages of quantum wire (QWR) formation studying the evolution of the growth front for InAs coverages below the critical thickness, θc, determined by reflection high energy electron diffraction (RHEED). Our results obtained by in situ measurement of the accumulated stress evolution during InAs growth on InP(001) show that the relaxation process starts at a certain InAs coverage θRθR this ensemble of isolated nanostructures progressively evolves towards QWRs that cover the whole surface for θ = θc. These results allow for a better understanding of the self-assembling process of QWRs and enable the study of the individual properties of In…

Facilitating Team Reflexivity About Communication

2016

This article explores how team facilitation can promote team reflexivity about communication. We present a case study that was conducted within a participatory action research framework with a Top Management Team for an international manufacturing company. We identify and analyze five key interventions that promoted team reflexivity. These interventions included activities such as (a) framing the facilitation, (b) inquiring into the key issues, (c) role modeling feedback, (d) positive storytelling, and (e) reflecting on concrete communication actions. The findings suggest that reflexivity can be enhanced through positive storytelling and emotion, framing and contextual sensitivity, and add…
