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.

Spatial and temporal variability and ecological processes in the epibenthic assemblages of the northern Adriatic Sea

Several coralligenous reefs occur in the soft bottoms of the northern Adriatic continental shelf. Mediterranean coralligenous habitats are characterised by high species diversity and are intrinsically valuable for their biological diversity and for the ecological processes they support. The conservation and management of these habitats require quantifying spatial and temporal variability of their benthic assemblages. This PhD thesis aims to give a relevant contribution to the knowledge of the structure and dynamics of the epibenthic assemblages on the coralligenous subtidal reefs occurring in the northern Adriatic Sea. The epibenthic assemblages showed a spatial variation larger compared to temporal changes, with a temporal persistence of reef-forming organisms. Assemblages spatial heterogeneity has been related to morphological features and geographical location of the reefs, together with variation in the hydrological conditions. Manipulative experiments help to understand the ecological processes structuring the benthic assemblages and maintaining their diversity. In this regards a short and long term experiment on colonization patterns of artificial substrata over a 3-year period has been performed in three reefs, corresponding to the three main types of assemblages detected in the previous study. The first colonisers, largely depending by the different larval supply, played a key role in determining the heterogeneity of the assemblages in the early stage of colonisation. Lateral invasion, from the surrounding assemblages, was the driver in structuring the mature assemblages. These complex colonisation dynamics explained the high heterogeneity of the assemblages dwelling on the northern Adriatic biogenic reefs. The buildup of these coralligenous reefs mainly depends by the bioconstruction-erosion processes that has been analysed through a field experiment. Bioconstruction, largely due to serpulid polychaetes, prevailed on erosion processes and occurred at similar rates in all sites. Similarly, the total energy contents in the benthic communities do not differ among sites, despite being provided by different species. Therefore, we can hypothesise that both bioconstruction processes and energetic storage may be limited by the availability of resources. Finally the major contribution of the zoobenthos compared to the phytobenthos to the total energetic content of assemblages suggests that the energy flow in these benthic habitats is primarily supported by planktonic food web trough the filter feeding invertebrates.

Diversity of cwp loci in clinical isolates of Clostridium difficile

An increased incidence of Clostridium difficile infection (CDI) is associated with the emergence of epidemic strains characterised by high genetic diversity. Among the factors that may have a role in CDI there is a family of 29 paralogs, the cell wall proteins (CWPs), which compose the outer layer of the bacterial cell and are likely to be involved in colonisation. Previous studies have shown that 12 of the29 cwp genes are clustered in the same region, named after slpA (cwp1) the slpA locus, whereas the remaining 17 paralogs are distributed throughout the genome. The variability of 14 of these 17 cwp paralogs was determined in 40 C. difficile clinical isolates belonging to six of the currently prevailing PCR ribotypes. Based on sequence conservation, these cwp genes were divided into two groups, one comprising cwp loci having highly conserved sequences in all isolates, and the other 5 loci showing low genetic conservation between isolates of the same PCR ribotype as well as between different PCR ribotypes. Three conserved CWPs, Cwp16, Cwp18 and Cwp25, and two variable ones, Cwp26 and Cwp27, were characterised further by Western blot analysis of total cell extracts or S-layer preparations of the C. difficile clinical isolates. Expression of genetically invariable CWPs is well conserved in all isolates, while genetically variable CWPs are not always expressed at comparable levels even in strains containing identical sequences but belonging to different PCR ribotypes. In addition, we chose to analyse the immune response obtained in a protection experiment, carried out in hamsters, using a protein microarray approach to study the in vivo expression and the immunoreactivity of several surface proteins, including 18 Cwps.

Cantate dialogiche e serenate (1706-1710) di Georg Friedrich Händel

La dissertazione è uno studio monografico delle cantate dialogiche e delle serenate a più voci e strumenti composte da Händel in Italia negli anni 1706-1710. Insieme ai drammi per musica e agli oratori coevi, le quattro cantate "Aminta e Fillide" HWV 83, "Clori, Tirsi e Fileno" HWV 96, "Il duello amoroso" HWV 82, "Apollo e Dafne" HWV 122 e le due serenate "Aci, Galatea e Polifemo" HWV 72 e "Olinto pastore arcade alle glorie del Tebro" HWV 143 costituiscono le prime importanti affermazioni di Händel come compositore di musica vocale. Le sei composizioni sono state studiate sotto l’aspetto storico-letterario, drammaturgico-musicale e della committenza, con l’obiettivo di individuare intersecazioni fra questi piani. I testi poetici, di cui si è curata l’edizione, sono stati analizzati da un punto di vista storico e stilistico e collocati nel particolare contesto romano del primo Settecento, in cui la proibizione di ogni spettacolo teatrale determinò, sotto la spinta di una raffinata committenza, un ‘drammatizzazione’ dei generi della cantata e della serenata. L’analisi musicale di ciascuna composizione è stata dunque finalizzata a una lettura ‘drammaturgica’, che ha portato alla individuazione dei dispositivi di ascendenza teatrale nella scelte compositive di Händel. Lo studio si conclude con un selettivo confronto con le cantate e le serenate scritte negli stessi anni a Roma da Alessandro Scarlatti.

La cerchia di Giulio Clovio: gli incontri, i viaggi, le amicizie di un artista europeo

La tesi riguarda il miniatore Giulio Clovio (Grižane, Croazia, 1498 – Roma, 1578), considerandolo come il fulcro di una rete di relazioni tra committenti, artisti e letterati. È divisa in tre parti, seguendo la vita dell’artista: giovinezza (1498-1534), maturità (1534-1561) e vecchiaia (1561-1578). Tra i committenti più significativi: Domenico e Marino Grimani e il cardinale Alessandro Farnese. Tra gli artisti italiani: Giulio Romano, Girolamo dai Libri, Valerio Belli, Sofonisba Anguissola. Tra gli artisti europei: Francisco de Hollanda, Pieter Brueghel il Vecchio, Bartholomeus Sprangher, El Greco e Lampsonio.

Per un'archeologia del lavoro in eta' protobizantina. Organizzazione e committenza del cantiere edilizio attraverso i marchi dei marmorari

La ricerca riguarda lo studio del cantiere edilizio protobizantino, con particolare riferimento al ciclo della lavorazione del marmo. Quest’ultimo viene analizzato sotto il profilo amministrativo, tecnico, sociale ed artigianale. L’elemento guida della ricerca sono i marchi dei marmorari, sigle apposte da funzionari e maestranze durante il processo produttivo. Dapprima, fonti letterarie ed epigrafiche, tra cui le sigle di cava e officina su marmo, vengono esaminate per ricostruire il sistema alto-imperiale di amministrazione delle cave e di gestione dei flussi marmorei, nonché l’iter tecnico-artigianale adottato per la produzione dei manufatti. Il confronto con i dati disponibili per la tarda antichità, con particolare riferimento alle cave di Proconneso, evidenzia una sostanziale continuità della prassi burocratico-amministrativa, mentre alcuni cambiamenti si riscontrano nell’ambito produttivo-artigianale. Il funzionamento degli atelier marmorari viene approfondito attraverso lo studio dei marchi dei marmorari. Si tratta di caratteri greci singoli, multipli o monogrammi. Una ricognizione sistematica delle sigle dalla pars Orientalis dell’impero, reperite in bibliografia o da ricognizioni autoptiche, ha portato alla raccolta di circa 2360 attestazioni. Per esse si propone una classificazione tipologica tra sigle di cava, stoccaggio, officina. Tra le sigle di cava si annoverano sigle di controllo, destinazione/committenza, assemblaggio/posizionamento. Una particolare attenzione è riservata alle sigle di officina, riferibili ad un nome proprio di persona, ovvero al πρωτομαΐστωρ, il capo-bottega che supervisionava il lavoro dei propri artigiani e fungeva da garante del prodotto consegnato alla committenza. Attraverso lo studio comparato delle sigle reperite a Costantinopoli e in altri contesti si mette in luce la prassi operativa adottata dagli atelier nei processi di manifattura, affrontando anche il problema delle maestranze itineranti. Infine, sono analizzate fonti scritte di varia natura per poter collocare il fenomeno del marmo in un contesto socio-economico più ampio, con particolare riferimento alle figure professionali ed artigianali coinvolte nei cantieri e al problema della committenza.

Le désert et la littérature de voyage européenne du XIXe siècle

L'Europe commence à découvrir le désert à la fin du XVIIIe siècle. Ce milieu présente des aspects multiples aux premiers explorateurs, qui le décrivent comme un lieu vivant et varié. La géopolitique constitue le premier approche d'analyse : le désert peut être rendu plus viable si mieux administré, donc libre de la domination ottomane. Au cours du siècle, le tourisme se développe, aussi en raison de la colonisation ; l'expérience du désert devient commune, et les voyageurs partent en quête d'une expérience spirituelle aussi bien que d'une aventure. Le désert devient un écran de projection pour la rêverie et les souvenirs des Européens (la Bible et les topos traditionnels demeurent actifs dans l'imaginaire occidental) ; seules certaines caractéristiques de ce milieu sont dès lors appréciées par les voyageurs. Ensuite, avec l'âge du Réalisme, devient objet d'appréciation de la part des peintres. Grâce à la médiation de l'art, la littérature commence à regarder au désert d'un point de vue esthétique, et elle lui reconnaît un charme de la nudité et du dépouillement. La mort et le minéral caractérisent ce milieu vers la fin du siècle ; le désert se vide, et devient le "désert de sable" que nous tous connaissons aujourd'hui.

Il libro di spese diverse di Lorenzo Lotto. Analisi e commento

Il progetto si concentra sull’analisi ed il commento del libro dei conti di Lorenzo Lotto. Esso viene conservato nell’Archivio storico della Santa Casa di Loreto, ed è meglio conosciuto con il nome apocrifo di Libro di spese diverse. Possiamo considerarlo uno dei più significativi documenti del Rinascimento italiano: infatti esso ci parla dei rapporti che l’artista ha intessuto con committenti, colleghi ed amici, rivelando tanto la sua condotta di vita che la sua attività. È una ricerca che tenta di concentrarsi sull’artista attraverso una lettura più corretta di questa fonte: infatti in passato il Libro di spese diverse era considerato un diario e studiato attraverso una visione non consona al genere di riferimento.
