Traces de terre, traces d'encre... La rappresentazione dello spazio nella letteratura caraibica. (Francofona e Anglofona)

This study concerns the representation of space in Caribbean literature, both francophone and Anglophone and, in particular, but not only, in the martinican literature, in the works of the authors born in the island. The analysis focus on the second half of the last century, a period in which the martinican production of novels and romances increased considerably, and where the representation and the rule of space had a relevant place. So, the thesis explores the literary modalities of this representation. The work is constituted of 5 chapters and the critical and methodological approaches are both of an analytical and comparative type. The first chapter “The caribbean space: geography, history and society” presents the geographic context, through an analysis of the historical and political major events occurred in the Caribbean archipelago, in particular of the French Antilles, from the first colonization until the départementalisation. The first paragraph “The colonized space: historical-political excursus” the explores the history of the European colonization that marked forever the theatre of the relationship between Europe, Africa and the New World. This social situation take a long and complex process of “Re-appropriation and renegotiation of the space”, (second paragraph) always the space of the Other, that interest both the Antillean society and the writers’ universe. So, a series of questions take place in the third paragraph “Landscape and identity”: what is the function of space in the process of identity construction? What are the literary forms and representations of space in the Caribbean context? Could the writing be a tool of cultural identity definition, both individual and collective? The second chapter “The literary representation of the Antillean space” is a methodological analysis of the notions of literary space and descriptive gender. The first paragraph “The literary space of and in the novel” is an excursus of the theory of such critics like Blanchot, Bachelard, Genette and Greimas, and in particular the recent innovation of the 20th century; the second one “Space of the Antilles, space of the writing” is an attempt to apply this theory to the Antillean literary space. Finally the last paragraph “Signs on the page: the symbolic places of the antillean novel landscape” presents an inventory of the most recurrent antillean places (mornes, ravines, traces, cachots, En-ville,…), symbols of the history and the past, described in literary works, but according to new modalities of representation. The third chapter, the core of the thesis, “Re-drawing the map of the French Antilles” focused the study of space representation on francophone literature, in particular on a selected works of four martinican writers, like Roland Brival, Édouard Glissant, Patrick Chamoiseau and Raphaël Confiant. Through this section, a spatial evolution comes out step by step, from the first to the second paragraph, whose titles are linked together “The novel space evolution: from the forest of the morne… to the jungle of the ville”. The virgin and uncontaminated space of the Antilles, prior to the colonisation, where the Indios lived in harmony with the nature, find a representation in both works of Brival (Le sang du roucou, Le dernier des Aloukous) and of Glissant (Le Quatrième siècle, Ormerod). The arrival of the European colonizer brings a violent and sudden metamorphosis of the originary space and landscape, together with the traditions and culture of the Caraïbes population. These radical changes are visible in the works of Chamoiseau (Chronique des sept misères, Texaco, L’esclave vieil homme et le molosse, Livret des villes du deuxième monde, Un dimanche au cachot) and Confiant (Le Nègre et l’Amiral, Eau de Café, Ravines du devant-jour, Nègre marron) that explore the urban space of the creole En-ville. The fourth chapter represents the “2nd step: the Anglophone novel space” in the exploration of literary representation of space, through an analytical study of the works of three Anglophone writers, the 19th century Lafcadio Hearn (A Midsummer Trip To the West Indies, Two Years in the French West Indies, Youma) and the contemporary authors Derek Walcott (Omeros, Map of the New World, What the Twilight says) and Edward Kamau Brathwaite (The Arrivants: A New World Trilogy). The Anglophone voice of the Caribbean archipelago brings a very interesting contribution to the critical idea of a spatial evolution in the literary representation of space, started with francophone production: “The spatial evolution goes on: from the Martiniques Sketches of Hearn… to the modern bards of Caribbean archipelago” is the new linked title of the two paragraphs. The fifth chapter “Extended look, space shared: the Caribbean archipelago” is a comparative analysis of the results achieved in the prior sections, through a dialogue between all the texts in the first paragraph “Francophone and Anglophone representation of space compared: differences and analogies”. The last paragraph instead is an attempt of re-negotiate the conventional notions of space and place, from a geographical and physical meaning, to the new concept of “commonplace”, not synonym of prejudice, but “common place” of sharing and dialogue. The question sets in the last paragraph “The “commonplaces” of the physical and mental map of the Caribbean archipelago: toward a non-place?” contains the critical idea of the entire thesis.

Estimating crustal deformation from geodetic data

By the end of the 19th century, geodesy has contributed greatly to the knowledge of regional tectonics and fault movement through its ability to measure, at sub-centimetre precision, the relative positions of points on the Earth’s surface. Nowadays the systematic analysis of geodetic measurements in active deformation regions represents therefore one of the most important tool in the study of crustal deformation over different temporal scales [e.g., Dixon, 1991]. This dissertation focuses on motion that can be observed geodetically with classical terrestrial position measurements, particularly triangulation and leveling observations. The work is divided into two sections: an overview of the principal methods for estimating longterm accumulation of elastic strain from terrestrial observations, and an overview of the principal methods for rigorously inverting surface coseismic deformation fields for source geometry with tests on synthetic deformation data sets and applications in two different tectonically active regions of the Italian peninsula. For the long-term accumulation of elastic strain analysis, triangulation data were available from a geodetic network across the Messina Straits area (southern Italy) for the period 1971 – 2004. From resulting angle changes, the shear strain rates as well as the orientation of the principal axes of the strain rate tensor were estimated. The computed average annual shear strain rates for the time period between 1971 and 2004 are γ˙1 = 113.89 ± 54.96 nanostrain/yr and γ˙2 = -23.38 ± 48.71 nanostrain/yr, with the orientation of the most extensional strain (θ) at N140.80° ± 19.55°E. These results suggests that the first-order strain field of the area is dominated by extension in the direction perpendicular to the trend of the Straits, sustaining the hypothesis that the Messina Straits could represents an area of active concentrated deformation. The orientation of θ agree well with GPS deformation estimates, calculated over shorter time interval, and is consistent with previous preliminary GPS estimates [D’Agostino and Selvaggi, 2004; Serpelloni et al., 2005] and is also similar to the direction of the 1908 (MW 7.1) earthquake slip vector [e.g., Boschi et al., 1989; Valensise and Pantosti, 1992; Pino et al., 2000; Amoruso et al., 2002]. Thus, the measured strain rate can be attributed to an active extension across the Messina Straits, corresponding to a relative extension rate ranges between < 1mm/yr and up to ~ 2 mm/yr, within the portion of the Straits covered by the triangulation network. These results are consistent with the hypothesis that the Messina Straits is an important active geological boundary between the Sicilian and the Calabrian domains and support previous preliminary GPS-based estimates of strain rates across the Straits, which show that the active deformation is distributed along a greater area. Finally, the preliminary dislocation modelling has shown that, although the current geodetic measurements do not resolve the geometry of the dislocation models, they solve well the rate of interseismic strain accumulation across the Messina Straits and give useful information about the locking the depth of the shear zone. Geodetic data, triangulation and leveling measurements of the 1976 Friuli (NE Italy) earthquake, were available for the inversion of coseismic source parameters. From observed angle and elevation changes, the source parameters of the seismic sequence were estimated in a join inversion using an algorithm called “simulated annealing”. The computed optimal uniform–slip elastic dislocation model consists of a 30° north-dipping shallow (depth 1.30 ± 0.75 km) fault plane with azimuth of 273° and accommodating reverse dextral slip of about 1.8 m. The hypocentral location and inferred fault plane of the main event are then consistent with the activation of Periadriatic overthrusts or other related thrust faults as the Gemona- Kobarid thrust. Then, the geodetic data set exclude the source solution of Aoudia et al. [2000], Peruzza et al. [2002] and Poli et al. [2002] that considers the Susans-Tricesimo thrust as the May 6 event. The best-fit source model is then more consistent with the solution of Pondrelli et al. [2001], which proposed the activation of other thrusts located more to the North of the Susans-Tricesimo thrust, probably on Periadriatic related thrust faults. The main characteristics of the leveling and triangulation data are then fit by the optimal single fault model, that is, these results are consistent with a first-order rupture process characterized by a progressive rupture of a single fault system. A single uniform-slip fault model seems to not reproduce some minor complexities of the observations, and some residual signals that are not modelled by the optimal single-fault plane solution, were observed. In fact, the single fault plane model does not reproduce some minor features of the leveling deformation field along the route 36 south of the main uplift peak, that is, a second fault seems to be necessary to reproduce these residual signals. By assuming movements along some mapped thrust located southward of the inferred optimal single-plane solution, the residual signal has been successfully modelled. In summary, the inversion results presented in this Thesis, are consistent with the activation of some Periadriatic related thrust for the main events of the sequence, and with a minor importance of the southward thrust systems of the middle Tagliamento plain.

Survey on the spirilar flora of Lagomorphs

Members of the genera Campylobacter and Helicobacter have been in the spotlight in recent decades because of their status as animals and/or humans pathogens, both confirmed and emerging, and because of their association with food-borne and zoonotic diseases. First observations of spiral shaped bacteria or Campylobacter-like organisms (CLO) date back to the end of the 19th century, however the lack of adequate isolation methods hampered further research. With the introduction of methods such as selective media and a filtration procedure during the 1970s led to a renewed interest in Campylobacter, especially as this enabled elucidation of their role in human hosts. On the other hand the classification and identification of these bacteria was troublesome, mainly because of the biochemical inertness and fastidious growth requirements. In 1991, the taxonomy of Campylobacter and related organisms was thoroughly revised, since this revision several new Campylobacter and Helicobacter species have been described. Moreover, thanks to the introduction of a polyphasic taxonomic practice, the classification of these novel species is well-founded. Indeed, a polyphasic approach was here followed for characterizing eight isolates obtained from rabbits epidemiologically not correlated and as a result a new Campylobacter species was proposed: Campylobacter cuniculorum (Chapter 1). Furthermore, there is a paucity of data regarding the occurrence of spiral shaped enteric flora in leporids. In order to define the prevalence both of this new species and other CLO in leporids (chapter 2), a total of 85 whole intestinal tracts of rabbits reared in 32 farms and 29 capture hares, epidemiologically not correlated, were collected just after evisceration at the slaughterhouse or during necroscopy. Examination and isolation methods were varied in order to increase the sensibility level of detection, and 100% of rabbit farms resulted positive for C. cuniculorum in high concentrations. Moreover, in 3.53% of the total rabbits examined, a Helicobacter species was detected. Nevertheless, all hares resulted negative both for Campylobacter or Helicobacter species. High prevalence of C. cuniculorum were found in rabbits, and in order to understand if this new species could play a pathological role, a study on some virulence determinants of C. cuniculorum was conducted (Chapter 3). Although this new species were able to adhere and invade, exert cytolethal distending toxin-like effects although at a low titre, a cdtB was not detected. There was no clear relationship between source of isolation or disease manifestation and possession of statistically significantly levels of particular virulence-associated factors although, cell adhesion and invasion occurred. Furthermore, antibiotic susceptibility was studied (chapter 4) in Campylobacter and in Escherichia coli strains, isolated from rabbits. It was possible to find acquired resistance of C. cuniculorum to enrofloxacin, ciprofloxacin and erytromycin. C. coli isolate was susceptible to all antimicrobial tested and moreover it is considered as a wild-type strain. Moreover, E. coli was found at low caecal concentration in rabbits and 30 phenotypes of antibiotic resistance were founded as well as the high rate of resistances to at least one antibiotic (98.1%). The majority of resistances were found from strains belonging to intensive farming system. In conclusion, in the course of the present study a new species isolated from rabbits was described, C. cuniculorum, and its high prevalence was established. Nevertheless, in hare samples no Campylobacter and Helicobacter species were detected. Some virulence determinants were further analyzed, however further studied are needed to understand the potential pathogenicity of this new species. On the other hand, antimicrobial susceptibility was monitored both in C. cuniculorum and indicator bacteria and acquired resistance was observed towards some antibiotics, indicating a possible role of rabbitries in the diffusion of antibiotic resistance. Further studies are necessary to describe and evaluate the eventual zoonotic role of Campylobacter cuniculorum.

An advanced analytical study on linseed oil paint binder

Drying oils, and in particular linseed oil, were the most common binding media employed in painting between XVI and XIX centuries. Artists usually operated some pre-treatments on the oils to obtain binders with modified properties, such as different handling qualities or colour. Oil processing has a key role on the subsequent ageing of and degradation of linseed oil paints. In this thesis a multi-analytical approach was adopted to investigate the drying, polymerization and oxidative degradation of the linseed oil paints. In particular, thermogravimetry analysis (TGA), yielding information on the macromolecular scale, were compared with gas-chromatography mass-spectrometry (GC-MS) and direct exposure mass spectrometry (DEMS) providing information on the molecular scale. The study was performed on linseed oils and paint reconstructions prepared according to an accurate historical description of the painting techniques of the 19th century. TGA revealed that during ageing the molecular weight of the oils changes and that higher molecular weight fractions formed. TGA proved to be an excellent tool to compare the oils and paint reconstructions. This technique is able to highlight the different physical behaviour of oils that were processed using different methods and of paint layers on the basis of the different processed oil and /or the pigment used. GC/MS and DE-MS were used to characterise the soluble and non-polymeric fraction of the oils and paint reconstructions. GC/MS allowed us to calculate the ratios of palmitic to stearic acid (P/S), and azelaic to palmitic acid (A/P) and to evaluate effects produced by oil pre-treatments and the presence of different pigments. This helps to understand the role of the pre-treatments and of the pigments on the oxidative degradation undergone by siccative oils during ageing. DE-MS enabled the various molecular weight fractions of the samples to be simultaneously studied, and thus helped to highlight the presence of oxidation and hydrolysis reactions, and the formation of carboxylates that occur during ageing and with the changing of the oil pre-treatments and the pigments. The combination of thermal analysis with molecular techniques such as GC-MS, DEMS and FTIR enabled a model to be developed, for unravelling some crucial issues: 1) how oil pre-treatments produce binders with different physical-chemical qualities, and how this can influence the ageing of an oil paint film; 2) which is the role of the interaction between oil and pigments in the ageing and degradation process.

Dalle feste di nozze alle orchestre di stato: Maria Lătărețu e l'invenzione della muzică populară

Le musiche “popolaresche” urbane, in genere trascurate nella letteratura etnomusicologica, sono state quasi completamente ignorate nel caso della Romania. Il presente studio si propone di colmare almeno in parte questa lacuna, indagando questo fenomeno musicale nella Bucarest degli anni Trenta e Quaranta del Novecento. Le musiche esaminate sono tuttavia inserite entro una cornice storica più ampia, che data a partire dalla fine del XVIII secolo, e messe in relazione con alcune produzioni di origine rurale che con queste hanno uno stretto rapporto. Il caso di Maria Lătărețu (1911-1972) si è rivelato particolarmente fecondo in questo senso, dal momento che la cantante apparteneva ad entrambi i versanti musicali, rurale e urbano, e nepadroneggiava con disinvoltura i rispettivi repertori. Dopo il suo trasferimento nella capitale, negli anni Trenta, è diventata una delle figure di maggior spicco di quel fenomeno noto come muzică populară (creazione musicale eminentemente urbana e borghese con radici però nel mondo delle musiche rurali). L’analisi del repertorio (o, per meglio dire, dei due repertori) della Lătărețu, anche nel confronto con repertori limitrofi, ha permesso di comprendere più da vicino alcuni dei meccanismi musicali alla base di questa creazione. Un genere musicale che non nasce dal nulla nel dopo-guerra, ma piuttosto continua una tradizione di musica urbana, caratterizzata in senso locale, ma influenzata dal modello della canzone europea occidentale, che data almeno dagli inizi del Novecento. Attraverso procedimenti in parte già collaudati da compositori colti che sin dal XIX secolo, in Romania come altrove, si erano cimentati con la creazione di melodie in stile popolare o nell’armonizzazione di musiche di provenienza contadina, le melodie rurali nel bagaglio della cantante venivano trasformate in qualcosa di inedito. Una trasformazione che, come viene dimostrato efficacemente nell’ultimo capitolo, non investe solo il livello superficiale, ma coinvolge in modo profondo la sintassi musicale.

Paul Flandrin (1811-1902), un nuovo sguardo sul paesaggio dell'Ottocento

Questa ricerca ha l’obiettivo di dare nuovi contributi alla conoscenza della pittura di paesaggio francese nell’Ottocento attraverso lo studio dell’opera di Paul Flandrin (1811-1902). Flandrin si colloca al crocevia di esperienze fondamentali nella ricerca artistica di metà Ottocento: l’eredità di Camille Corot, l’insegnamento di Jean-Auguste Dominique Ingres, la pratica del lavoro en plein air, la tradizione del paesaggio neoclassico. Il corpus di opere del pittore lionese Paul Flandrin (1811-1902) ricostruito in questa tesi è frutto di una sistematica operazione di ricerca sul campo e viene in seguito analizzato alla luce dei recenti studi sulla pittura di paesaggio neoclassico in Francia nel XIX secolo. La ricerca si fonda su una grande quantità di materiale inedito: dipinti, disegni, taccuini di studio en plein air, corrispondenza con colleghi e amici. Da questa ricerca la fisionomia artistica di Paul Flandrin emerge ben individuata singolarmente e al tempo stesso ancorata al contesto storico-artistico attraverso le relazioni con i colleghi, l’utilizzo di determinate tecniche, la frequentazione di mete comuni ai paesaggisti suoi contemporanei, la decisa presa di posizione a favore del paesaggio neoclassico.

I manufatti egizi ed egittizzanti in Sicilia

Il progetto di ricerca si è posto l'obiettivo di analizzare una serie di manufatti egizî e di tradizione egizia della Sicilia preromana e di evidenziare le eventuali sopravvivenze della cultura egittizzante sull’isola fino all'età tardoantica. La realizzazione di un corpus, aggiornato sulla scorta di nuovi rinvenimenti, di recenti riletture e di studi su materiali inediti custoditi nei musei siciliani, ha contribuito a tracciare una mappa distributiva delle aree di rinvenimento e di attestazione, con particolare riferimento alle diverse etnie che recepiscono tali prodotti e alla possibilità di ricostruire l’ambientazione storica della domanda diretta o indiretta. Si è scelto di privilegiare lo studio tipologico, iconografico e iconologico di alcune “categorie” di materiali maggiormente documentati sull’isola, quali amuleti, scarabei e scaraboidi, cretule, ushabti, gioielli, bronzi figurati, gemme, con l’individuazione di riscontri in ambito mediterraneo. La documentazione delle testimonianze antiquarie contenenti notizie su reperti oggi non più reperibili ha permesso, infine, non solo l’acquisizione d’informazioni spesso ritenute perse, ma anche una comprensione storicizzata delle dinamiche del collezionismo siciliano e del suo ruolo nel più vasto ambito europeo dal XVII al XIX secolo. È stato importante, infatti, chiarire anche alcuni aspetti della cultura egittologica del periodo, legata in genere alla circolazione di stereotipi e alla mancanza di una conoscenza diretta della realtà faraonica.

La vision d'Athenes et de Constantinople dans les recits de voyage du XIXᵉ siecle

Le sujet de cette recherche est la perception chez les voyageurs occidentaux et grecs du XIXᵉ siècle de zones de la Méditerranée depuis toujours point d’intersections culturelles : les villes d’Athènes et de Constantinople. L’objectif de la recherche est de reconstruire la contribution des hommes de lettres, français et grecs, à la constitution de l’identité nationale selon le schéma mis en évidence par Benedict Anderson dans « Communautés Imaginées » On a tenté en se référant au corpus d’identifier dans la littérature de voyage du XIXᵉ siècle, dans le sillage de « Orientalismo » de Edward Said, comment Philhellénisme et Exotisme orientalisant, tous deux d’empreinte romantique, ont contribué à inventer pour Athènes une identité occidentale et pour Istanbul une identité orientale, ignorant presque l’existence entre les deux villes d’une commune matrice byzantine–ottomane ou mieux, l’appartenance commune à l’ensemble géopolitique de la Région Intermédiaire identifiée par Dimitri Kitsikis.

Families Stories. Rappresentazioni di famiglie nella letteratura per l'infanzia in Europa e negli Stati Uniti

In questa tesi dottorale viene preso in analisi il tema della famiglia, uno degli elementi fondanti della riflessione pedagogica, crocevia di una molteplicità di nuclei interpretativi con diramazioni e contaminazioni, con mutamenti attraverso le epoche storiche, rappresentati in pagine contenute nei Classici della letteratura per l’infanzia e nei migliori libri di narrativa contemporanea. Si tratta di un tema di grande ampiezza che ha comportato una scelta mirata di Autori che, nei loro romanzi hanno trattato questioni riguardanti la famiglia nelle sue pluralità delle sue tante accezioni, dalla vita familiare agli abbandoni, dalle infanzie senza famiglia alle famiglie altre. Nelle diverse epoche storiche, le loro narrazioni hanno lasciato un segno per l'originalità interpretativa che ancora oggi ci raccontano storie di vie familiale Dai romanzi ottocenteschi alle saghe fantasy degli ultimi cinquant’anni, fino ai picturebook, destinati ai più piccoli, le families stories possono costituire un materiale pedagogico privilegiato, sia offrendo occasioni di scoperta e conoscenza di sé e del mondo, attraverso le quali i lettori bambini, enigmatici frontalieri, varcano soglie verso altrovi misteriosi, sia fornendo spunti agli studiosi per approfondire tematiche multiple e complesse. Le families stories riflettono spesso in maniera critica le divergenze che possono manifestarsi tra le prassi individuate e studiate dalle scienze umane e sociali e le metafore narrative proposte dai numerosi Autori della letteratura per l’infanzia. Proponendo una prospettiva spesso spiazzante, esse interpretano la realtà a fondo, cogliendo i più piccoli ed inosservati particolari che, invece, hanno la capacità di rompere gli schemi socio-educativi dell’epoca storica in cui le storie prendono vita.
