L’Orientalismo tra vocazione imperialista, suggestioni esotiche e omoerotiche. Le rappresentazioni storiche del passaggio tra l’epoca omayyade e abbaside.

Lo studio si tratta di mettere in evidenza il cambiamento che ha subito il termine Oriente nel secolo XX in alcuni testi della letteratura italiana contemporanea. L’opera di Edward Said, L’Orientalismo è un testo di riferimento per i nostri studi. Nel quale abbiamo focalizzato l’attenzione su alcuni aspetti salienti: il concetto di orientalismo; l’interesse nei confronti dell’Oriente sul piano politico, scientifico, letterario; l’impossibilità di separare lo studioso dalle circostanze biografiche e sociali. Siamo riusciti, quindi, a stabilire che il cambiamento dell’immagine orientale dipende da tre fattori: lo scrittore (emittente), il soggetto (la fonte) ed il lettore (destinatario), dai quali si origina l’oggetto (il testo). Basandoci su questi tre elementi abbiamo cercato di inquadrare l’interesse letterario per l’Oriente vista da una triplice prospettiva: imperialismo, fascino ed erotismo. Per studiare le prime due prospettive, abbiamo scelto due opere. La prima presenta l’immagine dell’imperialismo, si tratta di Sanya, La moglie egiziana e il Romanzo dell’Oriente Moderno (1927) di Bruno Corra. La seconda prospettiva dove troviamo l’immagine dell’Oriente fascinoso è nello scritto di Annie Vivanti, La terra di Cleopatra (1925). Il punto centrale della tesi si tratta di studiare Annie Messina (1910-1996), è una scrittrice che ha uno stile peculiare ed un approccio tutto suo al tema dell’Oriente. I testi studiati sono : "Il mirto e la rosa" (1982), "Il banchetto dell'emiro" (1997) e "La principessa e il wâlî" (1996), tutti pubblicati dalla casa editrice Sellerio.L’unico pubblicato da Mondadori è "La palma di Rusafa" (1989). L’ultima parte del lavoro abbiamo esposto un profilo storico e socio-religioso della letteratura erotica araba. In cui abbiamo rintracciato le origini dell’immagine erotico dell’Oriente e il tema dell’omosessualità, mettendo a confronto il testo omosessuale di Messina con la letteratura italiana contemporanea.

Tectonics and kinematics of curved mountain belts: examples from the Andes and the Alps

Curved mountain belts have always fascinated geologists and geophysicists because of their peculiar structural setting and geodynamic mechanisms of formation. The need of studying orogenic bends arises from the numerous questions to which geologists and geophysicists have tried to answer to during the last two decades, such as: what are the mechanisms governing orogenic bends formation? Why do they form? Do they develop in particular geological conditions? And if so, what are the most favorable conditions? What are their relationships with the deformational history of the belt? Why is the shape of arcuate orogens in many parts of the Earth so different? What are the factors controlling the shape of orogenic bends? Paleomagnetism demonstrated to be one of the most effective techniques in order to document the deformation of a curved belt through the determination of vertical axis rotations. In fact, the pattern of rotations within a curved belt can reveal the occurrence of a bending, and its timing. Nevertheless, paleomagnetic data alone are not sufficient to constrain the tectonic evolution of a curved belt. Usually, structural analysis integrates paleomagnetic data, in defining the kinematics of a belt through kinematic indicators on brittle fault planes (i.e., slickensides, mineral fibers growth, SC-structures). My research program has been focused on the study of curved mountain belts through paleomagnetism, in order to define their kinematics, timing, and mechanisms of formation. Structural analysis, performed only in some regions, supported and integrated paleomagnetic data. In particular, three arcuate orogenic systems have been investigated: the Western Alpine Arc (NW Italy), the Bolivian Orocline (Central Andes, NW Argentina), and the Patagonian Orocline (Tierra del Fuego, southern Argentina). The bending of the Western Alpine Arc has been investigated so far using different approaches, though few based on reliable paleomagnetic data. Results from our paleomagnetic study carried out in the Tertiary Piedmont Basin, located on top of Alpine nappes, indicate that the Western Alpine Arc is a primary bend that has been subsequently tightened by further ~50° during Aquitanian-Serravallian times (23-12 Ma). This mid-Miocene oroclinal bending, superimposing onto a pre-existing Eocene nonrotational arc, is the result of a composite geodynamic mechanism, where slab rollback, mantle flows, and rotating thrust emplacement are intimately linked. Relying on our paleomagnetic and structural evidence, the Bolivian Orocline can be considered as a progressive bend, whose formation has been driven by the along-strike gradient of crustal shortening. The documented clockwise rotations up to 45° are compatible with a secondary-bending type mechanism occurring after Eocene-Oligocene times (30-40 Ma), and their nature is probably related to the widespread shearing taking place between zones of differential shortening. Since ~15 Ma ago, the activity of N-S left-lateral strike-slip faults in the Eastern Cordillera at the border with the Altiplano-Puna plateau induced up to ~40° counterclockwise rotations along the fault zone, locally annulling the regional clockwise rotation. We proposed that mid-Miocene strike-slip activity developed in response of a compressive stress (related to body forces) at the plateau margins, caused by the progressive lateral (southward) growth of the Altiplano-Puna plateau, laterally spreading from the overthickened crustal region of the salient apex. The growth of plateaux by lateral spreading seems to be a mechanism common to other major plateaux in the Earth (i.e., Tibetan plateau). Results from the Patagonian Orocline represent the first reliable constraint to the timing of bending in the southern tip of South America. They indicate that the Patagonian Orocline did not undergo any significant rotation since early Eocene times (~50 Ma), implying that it may be considered either a primary bend, or an orocline formed during the late Cretaceous-early Eocene deformation phase. This result has important implications on the opening of the Drake Passage at ~32 Ma, since it is definitely not related to the formation of the Patagonian orocline, but the sole consequence of the Scotia plate spreading. Finally, relying on the results and implications from the study of the Western Alpine Arc, the Bolivian Orocline, and the Patagonian Orocline, general conclusions on curved mountain belt formation have been inferred.

Integrating new and traditional approaches for the estimate of slip-rates of active faults: examples from the Mw 6.3, 2009 L’Aquila earthquake area, Central Italy

This thesis is based on the integration of traditional and innovative approaches aimed at improving the normal faults seimogenic identification and characterization, focusing mainly on slip-rate estimate as a measure of the fault activity. The L’Aquila Mw 6.3 April 6, 2009 earthquake causative fault, namely the Paganica - San Demetrio fault system (PSDFS), was used as a test site. We developed a multidisciplinary and scale‐based strategy consisting of paleoseismological investigations, detailed geomorphological and geological field studies, as well as shallow geophysical imaging and an innovative application of physical properties measurements. We produced a detailed geomorphological and geological map of the PSDFS, defining its tectonic style, arrangement, kinematics, extent, geometry and internal complexities. The PSDFS is a 19 km-long tectonic structure, characterized by a complex structural setting and arranged in two main sectors: the Paganica sector to the NW, characterized by a narrow deformation zone, and the San Demetrio sector to SE, where the strain is accommodated by several tectonic structures, exhuming and dissecting a wide Quaternary basin, suggesting the occurrence of strain migration through time. The integration of all the fault displacement data and age constraints (radiocarbon dating, optically stimulated luminescence (OSL) and tephrochronology) helped in calculating an average Quaternary slip-rate representative for the PSDFS of 0.27 - 0.48 mm/yr. On the basis of its length (ca. 20 km) and slip per event (up to 0.8 m) we also estimated a max expected Magnitude of 6.3-6.8 for this fault. All these topics have a significant implication in terms of surface faulting hazard in the area and may contribute also to the understanding of the PSDFS seismic behavior and of the local seismic hazard.

Stone architecture in Carso plateau. Settlement patterns and construction techniques of historic buildings

The use of stone and its types of processing have been very important in the vernacular architecture of the cross-border Carso. In Carso this represents an important legacy of centuries and has a uniform typological characteristic to a great extent. The stone was the main constituent of the local architecture, setting and shaping the human environment, incorporating the history of places through their specific symbolic and constructive language. The primary aim of this research is the recognition of the constructive rules and the values embedded in the Carso rural architecture by use and processing of stone. Central to this investigation is the typological reading, aimed to analyze the constructive language expressed by this legacy, through the analysis of the relationship between type, technique and material.

Valutazione affettiva del setting odontoiatrico in età evolutiva

Lo studio si pone l'obiettivo di approfondire il tema della valutazione affettiva del setting odontoiatrico in età evolutiva indagando se possa essere modulata da fattori quali: differenze di genere, specifici quadri patologici (Displasia Ectodermica e Patologie Sistemiche Croniche) responsabili di pregresse esperienze odontoiatriche e/o ospedalizzazioni; stato affettivo del bambino, stato affettivo del genitore. Materiali e metodi Studio 1. 85 soggetti [39 (19 maschi e 20 femmine) affetti da PSC e 46 (26 maschi e 20 femmine) soggetti sani] (range di età: 5-14 anni). Sono stati somministrati: un compito di valutazione immagini con 36 immagini (12 a contenuto piacevole, 12 neutro e 12 spiacevole) dallo IAPS e 12 immagini a contenuto odontoiatrico e dei questionari (MCDASf, CFSS-DS, TAD). Studio 2. 45 soggetti (19 maschi affetti da EDs e 26 maschi sani) (range di età: 5-14 anni). Sono stati somministrati: il compito di valutazione immagini precedentemente descritto e i questionari (MCDASf, CFSS-DS, TAD). Studio 3. 104 bambini (64 maschi and 40 femmine) (range di età: 5-14 anni) e uno dei genitori (19 padri and 69 madri). Sono stati somministrati i questionari MCDASf, CFSS-DS, TAD ai bambini e FDPQ, STAI-Y1, Y2-BDI-II ai genitori. Risultati: il contesto odontoiatrico ha una caratterizzazione affettiva distinta rispetto a contesti piacevoli, spiacevoli o neutri; specifici quadri patologici (EDs e PSC) non sembrano modulare il tipo di valutazione affettiva del contesto odontoiatrico; le femmine, attribuiscono al contesto odontoiatrico una valenza significativamente più spiacevole e una maggiore attivazione emotiva rispetto ai maschi; la paura del dolore odontoiatrico del genitore ha una correlazione con l’ansia dei bambini. Conclusione: è importante che l’odontoiatra consideri che la risposta emotiva delle bambine può essere caratterizzata da vissuti di paura con tendenza a comportamenti di allontanamento e valuti se la figura genitoriale rappresenta una risorsa o un elemento disturbante nella corso della seduta stessa.

Networking: the "making of" social networks. A closer look at the process and antecedents of some resourcing-oriented behaviors in organizations.

Social networks are one of the “hot” themes in people’s life and contemporary social research. Considering our “embeddedness” in a thick web of social relations is a study perspective that could unveil a number of explanations of how people may manage their personal and social resources. Looking at people’s behaviors of building and managing their social networks, seems to be an effective way to find some possible rationalization about how to help people getting the best from their resources . The main aim of this dissertation is to give a closer look at the role of networking behaviors. Antecedents, motivations, different steps and measures about networking behaviors and outcomes are analyzed and discussed. Results seem to confirm, in a different setting and time perspective, that networking behaviors include different types and goals that change over time. Effects of networking behaviors seem to find empirical confirmation through social network analysis methods. Both personality and situational self-efficacy seem to predict networking behaviors. Different types of motivational drivers seem to be related to diverse networking behaviors.
