Full textAbstract:
This thesis proposes a study on the rip currents development within a Mediterranean
embayed beach. The rip (or cross-shore) currents are among the most
investigated phenomena in the eld of coastal research, and their fame is due
to their environmental and socio-economic implications. The coastal areas are
considered as transition environments, where hydrosphere, lithosphere, biosphere,
atmosphere and (often) anthroposphere meet. The rip currents are
a crucial component of the coastal hydro-morphodynamic processes (hydrosphere
and lithosphere) (Short, 1999; Castelle et al., 2016), play a role in larval
recruitment processes (biosphere) (Shanks et al., 2010), and they are also
well known as risks source for beachgoers (anthroposphere) (Short and Hogan,
1994; Austin et al., 2012). However, the rip currents role along the Mediterranean
coasts is often neglected, and most of the literature concerns the rip
currents in oceanic environments. The aim of this research is a detailed description
of the rip currents behaviour along a Mediterranean embayed beach,
also considering the possible sea-level rise implications. The study area was
identied within Levanto bay, along the eastern Ligurian coast (NW Italy).
The research activity has been conducted through an integrated application
of several investigation methodologies, in order to obtain the best possible results
in therm of phenomena description. The rip currents individuation is
performed through a coastal video-monitoring system installed on the Levanto beach, and the collected data were processed through a dedicated software for
coastal video-monitoring (Brignone et al., 2012). Several eld surveys were
performed to obtain a full description of the geomorphological boundary conditions
(topo-bathymetric surveys and sedimentological sampling). The rip
currents description and evaluation were executed through the application of
the XBeach model (Roelvink et al., 2009), which is a well-known tool for
coastal modelling. Moreover, the modelling approach allowed the evaluation of
the possible rip currents response under dierent sea-level rise scenarios (local
sea-level projections to 2100) (Kopp et al., 2014). The obtained results show
a detailed description of the rip currents phenomena, showing their essential
role in the local coastal dynamics. The proposed research approach has proved
to be reliable for the rip currents investigation in the Mediterranean environment,
and it can be applied along any stretch of coast of the Mediterranean
Sea. Moreover, the modelling results showed a signicant relation between
sea-level rise and rip currents behaviour. The results of this study highlight
the role of the rip currents in the Mediterranean environment and represent a
rm basis for the rip currents investigation along the Mediterranean coasts.

Full textAbstract:
This study deals with reverse faults within intensely carbonated metalherzolites,
with related gold mineralisations, from the Voltri Massif, and in
particular within the Lavagnina Lakes area, in the Gorzente Valley. This area is
located in northwest Italy among the municipalities of Casaleggio Boiro, Lerma,
Mornese, and Bosio (Alessandria, Italy; GPS coordinates WGS84, 44.600685° N,
8.784286° E).
The Voltri Massif is a metaophiolitic complex, which occurs within the Eastern
edges of the Ligurian Alps. It is made up of of metaophiolitic rocks associated with
metasediments and slices of subcontinental lithospheric mantle. These rocks
underwent a complex Alpine tectono-metamorphic evolution, with blueschist- to
eclogite- facies peak metamorphism with variable retrogressive overprints.
For this study the analysed structures are the upper crustal deformational
events (UDC), from late- to post-orogenic linked to the collisional events. These
deformational events are linked to different structural regimes, and developed
during the late-Alpine to early-Appenine events.
The Lavagnina Lakes area is mainly characterised by outcrops of serpentinites,
lherzolites, metabasites, metagabbros, lenses of metasediments, and listvenites (in
decreasing order of volumetric extension). From a structural point of view, this
area is characterised by brittle to brittle-ductile systems of shear zones, with
associated carbonates and chalcedony-quartz veins associated with local gold
mineralisations.
Hydrothermal, carbon-rich fluids permeated the rocks and sustained these
deformation stages producing widespread and intense carbonate-rich alteration
zones, exclusive meso- and microstructures within carbonates fault zones, called
fault pearls, chalcedony shear veins along fault surfaces, widespread quartzchalcedony
and carbonates veining, and leading to local gold mineralisation.
The geological survey allowed identifying four main structures (Chapter 5) that
I studied in detail. In particular I studied the Bisciarelle Creek thrust fault for the
occurrence of meso- and microstructures never reported in literature, called fault
pearls. Their compositional and textural characteristics, described in chapter 5.3.4,
make the fault core of the Bisciarelle fault a peculiar geological object.
2
The data shown in chapter 7 provide constraints on the chemical properties of
the fluid that generate the intense carbonation along the Bisciarelle fault. Through
the mass transfer profiles was possible to identify and quantify those elements
transferred from the fluid to the rock and vice versa.
The morphometric image analysis results (Described in chapter 5.3.5) show
that the fault pearls have circular shape irrespective to the direction of observation
(parallel and orthogonal to the slickenlines), with values that indicate a nearly
perfect circular shape. These values are in line with the roundness values, hence
the fault pearls in three-dimensions can be considered as nearly perfect spheres or
as very spherical textures.
Single-spot SEM-EDS (Chapter 8) analyses show that ferroan dolomite makes
the pearl bands (CaO: 29.13±2.33 wt%; MgO: 19.03±4.86 wt%; FeO: 1.77±0.87
wt%) and that minor compositional variations across large and thin bands exist,
and that silica makes most of the chalcedony veins (SiO2: 97.97±3.23 wt%).
Elemental imaging by LA-ICPTOFMS (Chapter 8) provides a detailed account of
the distribution of chemical elements within pearls, matrix, and chalcedony shear
veins. Mineral paragenesis and elemental imaging by LA-ICP-TOFMS confirm the
hypothesis of hydrothermal derivation of the fault rock. This is best evaluated by
comparing the concentration ranges of the key trace elements As, Sb, In, Ga, Ag, Zn,
and Cu of fault pearls levels and chalcedony with those of the same elements in the
average upper crust. Such comparison clearly shows that the peak concentrations
of these elements are 5 (Cu, Zn) to 50 (Sb, In) times higher than those of the upper
crust, demonstrating that the Bisciarelle fault fluid was capable to transport and
deposit a suite of ore elements.
These evidences are fundamental to discuss the possible origin of the fluids that
developed the carbonation and the fluid-rock interactions along the Bisciarelle
thrust fault and along the main fault of the Lavagnina Lakes area.
On the basis of all the constraints described, the fault pearl features are
compatible with a genesis from a process called “transient” boiling in microfluidics.
This process occurs within cavities when a liquid is instantaneously overheated
and a vapour phase nucleates and expands up to explosive boiling, and so
generates a myriad of vapour bubbles. Such process, which occurred during mixed
mode fracturing in the fault, implies that pearls might reflect the liquid-vapour
3
fractionation of chemical elements in a boiling hydrothermal fluid during seismic
failure.
The close association of fault pearls with seismic-related structures such as submicron
carbonates coating of slip surfaces, quartz microtexture related to silica gel
deposition, syn-kinematic filamentous phase, injection veins with similar
characteristics and overpressure with respect to seismic pseudotachylites along
slip zone supports the hypothesis that fault pearls developed during shear events
at seismic rates, and hence are considerable as paleo-seismic events indicators.
Moreover I discuss the tectonic evolution of the Lavagnina Lakes area linked to
the syn-kynematic fluid rock interaction, the origin of the fluids and the gold
mineralisations of the area. The occurrence of syn-tectonic fluid flow and
consequent fluid-rock interaction (e.g. carbonation) along the two systems of
Reverse Shear Zones (RSZ1-RSZ2), is testified by: metasomatic alteration (ALT-1,
ALT-2, and ALT-3), at least three main systems of veins (V1, V2, and V3), and
hydraulic and cockade breccias. The evidence that the carbonation took place
along these structures, in particular along the RSZs systems, and within their
damage zones, highlights how these structures acted as important fluid pathways
and played a major control in the distribution of the ore deposits.
Finally, I stress out further consideration about the comparison between the
gold mineralisations of the area with the gold mineralisations of the whole Voltri Massif.

Full textAbstract:
Knowledge about deep-sea megabenthic communities has greatly increased during the last two decades thanks to the improvement of technical diving equipment, submersibles, remotely operated and autonomous vehicles. In the last 10 years, several studies, targeting the Mediterranean deep continental shelf or mesophotic zone (40-200 m), have reported the occurrence of rich hotspots of biodiversity, namely marine animal forests, dominated by habitat-forming species such as corals and sponges thriving in dim light conditions. This bathymetric range hosts the deepest extension of shallow-water animal forests as well as proper mesophotic assemblages thriving on the so-called roche du large ecosystems. These complex aggregations play a fundamental ecological role in the marine ecosystems (refuge effect, nursery area, benthic-pelagic coupling, biogeochemical cycles) and the characterization of their diversity and distribution is considered of primary interest worldwide. Explorations have depicted not only the diversity of these forests but also their vulnerability towards mechanical impacts inflicted by demersal fishing activities, especially in the overexploited Mediterranean basin. This leads to an urgent need to quantify the damages burdening on these sensitive ecosystems and to develop easy-to-apply tools to evaluate and monitor their environmental status, in order to provide effective conservation measures. This thesis aims to address these topics focusing on the marine animal forests of the Ligurian deep continental shelf.
The Ligurian Sea represents one of the most studied Mediterranean basins due to several extensive researches, which have characterized the benthic and pelagic fauna mainly through SCUBA diving (shallow waters) and trawl surveys (bathyal waters) since the beginning of the last century. On the other hand, a large knowledge gap still exists for this region regarding the deep circalittoral megabenthic communities and, overall, on the anthropic threats insisting on deep-sea communities. Indeed, considering the significant amount of professional and recreational fishermen operating at these depths in the Ligurian region, it was crucial to carry out an extensive investigation in this area.
In the present study, about 80 sites have been investigated during a four-years ROV survey conducted along the Ligurian deep continental shelf representing the most comprehensive study so far for the Italian waters. ROV footage was used to characterize the benthic biocoenoses thriving on soft and hard bottoms, determine the most relevant environmental factors driving their spatial distribution, and quantify the anthropogenic disturbance. Twelve major assemblages have been identified by means of community analysis, including gorgonian and hydrozoan forests, dense keratose sponge grounds, a Dendrophyllia cornigera facies, bryozoan beds and soft-bottom meadows of sabellids and alcyonaceans, some of them reported for the first time. Forests of black corals and Paramuricea macrospina aggregations have also been reported from the video footage, although with a more scattered distribution. The distribution of these assemblages is determined by different environmental parameters, namely depth, substrate type and inclination.
The abundance of marine litter herein observed is among the highest ever recorded in Europe, with maximum values up to 7900 items ha-1. Abandoned, lost or discarded fishing gears represent the 81% of the total sightings, with the highest abundance recorded on the deep rocky shoals facing the largest fishing harbors and fleets. The majority of the fishing gears observed is attributable to artisanal and recreational fishing activities, suggesting that these represent the main source of litter in the Ligurian Sea. Urban litter, mainly represented by plastic, has also been observed, generally with higher abundances nearby large cities and river mouths.
A multidisciplinary approach based on ROV explorations, background fishermen interviews and on-board bycatch monitoring has also been applied to obtain quantitative data on the impact of different fishing methods adopted within two Ligurian case studies. The study areas have been selected following a bathymetric point of view to study two different deep-sea ecosystems (a deep circalittoral coralligenous shoal exploited by a small-scale fishery and a trawling ground located nearby a cold-water coral thanatocoenoses), and the investigated parameters were designed to fulfil the criteria proposed by FAO for the identification of Vulnerable Marine Ecosystems (VMEs). A fine characterisation of the megabenthic assemblages and the fishing effort was obtained, as well as the quantification of no-target catches rates (with particular attention to structuring megabenthic invertebrates and rare species), and the frequency of gear entanglement and loss. This information allowed to initiate the process to delineate Fisheries Restricted Areas (FRAs), over these sensitive deep areas.
Finally, to evaluate the environmental status of megabenthic assemblages thriving on mesophotic coralligenous or rocky reefs at temperate latitudes, a multiparametric index (MACS) integrating all possible sources of ROV-based information regarding community structure and impacts has been developed and validated. This practical tool was thought to have a large-scale application within the on-going Marine Strategy monitoring programs of these ecosystems.
In conclusion, a georeferenced database of the location of diversity hotspots and sites of litter accumulation has been created, in order to set the baseline for the monitoring of Ligurian mesophotic sensitive animal forests. This dataset will provide managers and stakeholders the scientific information and the tools for the creation of an extensive network of deep-sea marine protected areas in the Ligurian basin.

Stephen Dyson's The Creation of the Roman Frontier employs various anthropological models to explain the development of Rome's republican frontiers. His treatment of the Ligurian frontier in the second century BC posits a Ligurian policy' crafted largely by the Senate and Roman frontier tacticians' (i.e. consuls). Dyson consciously avoids incorporating the pressures of domestic politics and the dynamics of aristocratic competition. But his insistence that these factors obscure policy continuities is incorrect. Politics determined policy. This thesis deals with the Ligurian frontier from 200 to 172 BC, years in which Roman involvement in the region was most intense. It shows that individual magistrates controlled policy to a much greater extent than Dyson and other scholars have allowed. The interplay between the competing forces of aristocratic competition and Senatorial consensus best explains the continuities and shifts in regional policy.The Creation of the Roman Frontier, l'uvre de Stephen Dyson, utilise plusieurs modèles anthropologiques pour illuminer le développement de la frontière républicaine. Son traitement de la frontière Ligurienne durant la deuxième siècle avant J.-C. postule une politique' envers les Liguriennes déterminer par le Sénat et les tacticiens de la frontière romain' (les consuls). Dyson fais exprès de ne pas tenir compte des forces de la politique domestique et la compétition aristocratique. Mais son insistance que ces forces cachent les continuités de la politique Ligurienne est incorrecte. Ce thèse évalue les développements dans la Ligurie entre les années 200 et 172 avant J.-C.les trentes ans pendant lesquelles les romains faisaient de la guerre à presque chaque année en Ligurie. La thèse montre que les individus influençaient la politique plus souvent et plus fortement que Dyson et autres historien(ne)s concèdent. Les continuités et changement dans la politique régionale sont mieux expliqués selon un cadre qui prend compte de la tension entre la compétition aristocratique et le consensus Sénatorial.

Il mio elaborato nasce dalle curiosità di voler approfondire e comprendere un tema molto attuale e dunque molto studiato negli ultimi decenni, ovvero quello dell’importanza sempre più incisiva che sta assumendo il fenomeno dell’esperienza nella mente dei consumatori. L’approfondimento sarà incentrato sul turismo esperienziale e l’attenzione sarà posta sia dal lato della domanda, sia dal lato dell’offerta. In particolare per quanto riguarda quest’ultima, si prenderà come caso studio Airbnb, la cui brand awareness è nota a tutti, cercando di capire se il suo lancio nel mercato delle esperienze può davvero creare un circolo virtuoso e non vizioso come spesso accade. Nell’epoca del turismo postmoderno ovvero quello che stiamo vivendo ora, non ci sono luoghi da scoprire poiché ogni luogo ormai è stato raggiunto. Non sono più le mete a fare la differenza ma le esperienze che si possono vivere, essendo ormai alla portata di tutti qualsiasi destinazione. Adesso è la maniera in cui si visita e si vive una località a fare la differenza, e Airbnb dunque sembra che stia puntando correttamente sul giusto trend del momento. Questo dovrebbe fare incontrare domanda e offerta, in questo nuovo approccio ambiente socioculturale e realtà ambientale si integrano e ai turisti è concessa la possibilità di agire rimodellando il territorio a loro uso e consumo. È chiaro che il territorio sia la base di partenza, ma questo da solo non basta per decretare il successo di una destinazione. Airbnb dunque sta cercando di proporre le esperienze in modo alternativo e plasmandole in base alle mode del momento, cercando di far convergere tutti gli interessi in gioco. La domanda dunque che mi pongo in questa ricerca è se airbnb sia davvero in grado di proporre un turismo alternativo, concentrandomi sulla regione Liguria e soprattutto se sia in grado di creare alleanze che creino sinergie per tutti i diversi attori in gioco.

Full textAbstract:
This thesis presents the results of a research project designed to reconstruct the Holocene vegetation history of eastern Liguria. The study area lies within the northern Apennines, a region from which few detailed late Quaternary palaeoenvironmental records had boon published and prior to this study no radiocarbon-dated pollen profiles had been reported. Presented hare are the results of pollen-stratigraphical investigations (including pollen concentration and pollen preservation data) from six Holocene peat sites, augmented by twelve radiocarbon dates. The data provide a first regional assessment of the mid- and late Holocene vegetation succession in Liguria as well as a detailed examination of the problems of sampling and interpretation encountered. The sites are situated at a range of altitudes between 831 m to 1481 m and consist of both infilled basins within drift deposits as well as shallow shelf sites. However most of the peat sequences began to form only 4000 to 5000 years ago. At three sites there are strong indications that peat formation only occurred after major disruption of local soils which locally may have been initiated by human (Chalcolithic) forest disturbances. Nevertheless there is also a lack of known early Holocene peat or lake sediments in much of northwestern Italy suggesting widespread climatic conditions inimical to peat development during that period. The biostratigraphical data indicate that Abies forests were common at altitudes of over 1000 a during the mid-Holocene but these declined from approximately 2000 BP and subsequently, woodlands were dominated by Fagus. Certain types suggest that these changes in forest composition could have been related to human activity, although forest clearance appears to have been restricted. The evidence overall suggests that there was major disruption of local soils during the mid- and late Holocene and it is suggested, therefore, that changes in soil moisture regimes possibly as a result of human disturbance, may have led to permanent changes in the vegetation cover.

Full textAbstract:
Introduzione:
Il virus del morbillo appartiene al genere Morbillivirus della famiglia dei Paramixoviridae. Il virione contiene un RNA non–segmentato, a singolo strand, di senso negativo di circa 16 kb. Il genoma contiene 6 geni che codificano per 6 proteine: proteina del nucleocapside (N), fosfoproteina (P), proteina della matrice (M), proteina di fusione (F), emoagglutinina (H) e proteina grande (L). Il virus del morbillo è nato come una zoonosi da quello della peste bovina (bovini peste). Ad oggi l'uomo è l'unico serbatoio naturale del virus. Il contagio avviene per via aerea, con il virus trasportato dalle goccioline di Flugge ovvero le micro gocce di saliva che vengono emesse attraverso il respirare lo starnutire o il tossire, e per contatto diretto o indiretto con i fluidi corporei di una persona malata (saliva, sperma, muco). Il virus penetra attraverso le mucose respiratorie e la congiuntiva e raggiunge i linfonodi dove si moltiplica e si diffonde così per via sistemica. L'incubazione dura circa 10 giorni. La viremia ha un picco in corrispondenza del 12° giorno dopo il contagio. E' una patologia particolarmente contagiosa per cui rientra tra le patologie da notifica obbligatoria. E' disponibile un vaccino. Il PNPV 2017-2019 prevede il Vaccino anti Morbillo-Parotite-Rosolia.
Il sistema di sorveglianza WHO si pone l’obiettivo di eliminare la trasmissione endemica mantenendo alti i livelli delle vaccinazioni e implementando il sistema di sorveglianza in particolar modo nell’ambito del WHO Global Measles and Rubella laboratory Network . A livello nazionale è stata istituita una rete di laboratori afferenti alla rete MoRoNet con obbligo di notifica all'Istituto Superiore di Sanità dei casi confermati positivi.
Oggetto di questa tesi è la descrizione dell'attività di sorveglianza per il morbillo della Regione Liguria negli ultimi cinque anni di lavoro.
Materiali e metodi:
Il laboratorio dell’UO Igiene dell’Ospedale Policlinico San Martino IRCCS, Università di Genova, raccoglie urine e tampone faringeo di pazienti con probabile o possibile morbillo, i casi da confermare e notificare su piattaforma MoRoNet quindi vengono analizzati come segue: estrazione degli acidi nucleici, amplificazione e sequenziamento del gene NP.
Ottenuta la sequenza è possibile determinare il genotipo del virus circolante e confrontarlo con altre sequenze di riferimento disponibili o con altri casi di morbillo. Questa informazione si ottiene costruendo un albero filogenetico con programmi bioinformatici di allineamento di sequenze e analisi di omologia tra sequenze.
Risultati:
Nel laboratorio di riferimento della Regione Liguria nel periodo 2015-2019 abbiamo raccolto 114 casi di morbillo da confermare. Di questi 57 casi sono stati confermati positivi. La media dell'età sul periodo è risultata essere 26,8 anni e la mediana 32 anni. In particolare abbiamo riscontrato la presenza dei focolai epidemici nella provincia di Imperia tra la fine 2017 e l' 2018.
I risultati dei test di caratterizzazione molecolare hanno permesso di identificare nei campioni raccolti nel 2018 un’unica variante di genotipo B3 circolante, mentre nel 2019 si è osservata la circolazione di diverse varianti appartenenti al genotipo D8 clade Manchester.UNK/3. Precedentemente le stagioni epidemiologiche sono state caratterizzate dalla circolazione della variante B3, quindi si conclude considerando attualmente una alternanza quasi annuale delle varianti circolanti di virus del morbillo.
Conclusioni e discussione:
Il morbillo continua a circolare in Italia e causare epidemie per le coperture vaccinali inadeguate nel corso degli anni, che hanno portato all’accumulo di ampie quote di popolazione suscettibili all’infezione. Le adesioni alla prima e alla seconda dose di vaccino MPR sono in aumento ma ancora inferiori al target del 95% e con una rilevante variabilità tra regioni.
Inoltre l'elevata età mediana dei casi indica che esistono ampie sacche di giovani adulti suscettibili, mentre i casi tra gli operatori sanitari Imperiesi evidenziano il problema della bassa copertura vaccinale tra questi ultimi. E' infine evidente la necessità di individuare nel Piano nazionale per l'eliminazione del morbillo e della rosolia congenita nuove azioni rispetto a quanto previsto nei precedenti Piani, per esempio rafforzare la copertura nella popolazione adulta.
Si conclude ricordando che l'obiettivo generale da raggiungere entro il 2023 è: incidenza <1 caso di morbillo / 1,000,000 popolazione, e tra gli obiettivi specifici rimane fondamentale raggiungere e mantenere una copertura vaccinale maggiore o uguale al 95% per la prima dose di morbillo.Introduction: Measles virus belongs to the genus Morbillivirus of the Paramixoviridae family. The virion contains a non-segmented RNA, a single strand, of a negative sense of approximately 16 kb. The genome contains 6 genes that code for 6 proteins: nucleocapsid protein (N), phosphoprotein (P), matrix protein (M), fusion protein (F), hemagglutinin (H) and large protein (L). Measles virus originated as a zoonosis from that of the bovine plague ( Rinderpest) . To date, man is the natural reservoir user of the virus. Contagion occurs by air, with the virus carried by the droplets of Flugge or the micro drops of saliva that are emitted through breathing, sneezing or coughing, and by direct or indirect contact with the body fluids of a sick person (saliva, sperm, mucus). The virus penetrates through the respiratory mucous membranes and the conjunctiva and observes the lymph nodes where it multiplies and spreads systemically. Incubation lasts approximately 10 days. The viraemia peaks in the correspondence on the 12th day after the infection. It is a particularly contagious pathology for which it falls under the pathologies of mandatory notification. A vaccine is available. The PNPV 2017-2019 provides for the measles-mumps-rubella vaccine.nThe WHO surveillance system aims to eliminate endemic transmission by keeping vaccination levels high and by implementing the surveillance system especially within the WHO Global Measles and Rubella laboratory Network. At national level, a network of laboratories has been set up belonging to the MoRoNet network with the obligation to notify the Istituto Superiore di Sanità of confirmed positive cases. The subject of this thesis is the description of the surveillance activity for measles of the Liguria Region in the last five years of work. Materials and methods: The laboratory of the Hygiene Unit of the Policlinico San Martino IRCCS Hospital, University of Genoa, collects urine and pharyngeal swab of patients with probable or possible measles, the cases to be confirmed and notified on the MoRoNet platform are therefore analyzed as follows: extraction of nucleic acids , amplification and sequencing of the NP gene. Once the sequence is obtained, it is possible to determine the genotype of the circulating virus and compare it with other available reference sequences or with other cases of measles. This information is obtained by building a phylogenetic tree with bioinformatic programs of sequence alignment and homology analysis between sequences. Results: In the reference laboratory of the Liguria Region in the period 2015-2019 we collected 114 cases of measles to be confirmed. Of these 57 cases were confirmed positive. The average age over the period was 26.8 years and the median 32 years. In particular, we found the presence of epidemic outbreaks in the province of Imperia between the end of 2017 and 2018. The results of the molecular characterization tests made it possible to identify a single circulating variant of genotype B3 in the samples collected in 2018, while in 2019 the circulation of several variants belonging to the D8 clade Manchester genotype was observed.UNK / 3. Previously the epidemiological seasons have been characterized by the circulation of the B3 variant, therefore it concludes considering at present an almost annual alternation of the circulating variants of measles virus. Conclusions and discussion: Measles continues to circulate in Italy and cause epidemics for inadequate vaccination coverage over the years, which have led to the accumulation of large portions of the population susceptible to infection. The adhesions to the first and second dose of MPR vaccine are increasing but still lower than the target of 95% and with a significant variability between regions. Furthermore, the high median age of the cases indicates that there are large pockets of susceptible young adults, while the cases among Imperia health workers highlight the problem of low vaccination coverage among the latter. Lastly, there is a clear need to identify new actions in the National Plan for the elimination of measles and congenital rubella compared to the previous Plans, for example to strengthen coverage in the adult population. It concludes by recalling that the general objective to be achieved by 2023 is: incidence <1 case of measles / 1,000,000 population, and among the specific objectives it remains essential to achieve and maintain a vaccination coverage greater than or equal to 95% for the first dose of measles .

Full textAbstract:
The most important Italian food are those with a label of quality; their high commercial value is due to some organoleptic characteristics that are the result of particular things; traditional processing, environmental conditions, soil composition, cultivar. These peculiarities make Italian products unique, but they inspire a high number of food frauds: the most widespread are the false declaration of provenance, or use of raw matters different than those declared. The legislative framework only concerns the documentation checks and actually there is very few legislation on food controls based on a scientific methods. This produces wide fraud phenomena, because paper documentation can be easy falsified. To stop the counterfeits of Made in Italy it is necessary to develop analytical methods to recognize the origin of a food. This is possible through the use of two different approaches, the Traceability that concerning the possibility to link a foodstuff to its provenance soil, and relating the raw matter with the finished product and Authentication that regards the ability to recognize a food among other similar products, but with different characteristics of lesser value, for example a different production technique, different possibility to perform studies with the use of the Trace Elements and, the Lanthanides. These elements do not seem to enter in the vegetable metabolism, but they are absorbed passively, and in this way they represent a fingerprint of the territory of origin. Through the use of the Elemental Analysis, with ICP-MS system and a chemometric approach, we developed an analytical method for Traceability and Authentication, and we tested them on some valuable Italian foodstuffs, mainly products in the Piemonte and Liguria region: milk and cream (Piemonte), Olive Oil obtained from Taggiasca cultivar (Liguria), Mushrooms (Piemonte and Liguria), Rice (Piemonte) and Wine must (Piemonte).

Full textAbstract:
In this PhD work, we carry out a geophysical and geological study of two classical examples of rifted continental margins: the Gulf of Lions (GoL), located in the Western Mediterranean, and the Tagus Abyssal Plain (TAP), located in the West Iberia margin. In spite of numerous previous studies of these regions, there is a debate on the crustal structure and the processes that led to the formation of the basin. Our study aims to 1) determine the nature of rocks forming the main geological domains of the basin, 2) define the tectonic structure of the basement and 3) place constrains and discuss the kinematics and tectonic and magmatic mechanisms involved in basin formation.
To study the GoL, we used a geophysical data set acquired during the SARDINIA-2006 survey by the Ifremer Institute (France). In particular, we used a Multi-Channel Seismic (MCS) line and a coincident Wide-Angle Seismic (WAS) profile. Altogether, these lines cover a seismic transect that runs NW-SE across the GoL until the central part of the Liguro-Provençal basin. The geophysical data used to study the TAP were collected during the FRAME-2018 survey within the framework of the FRAME project. We present spatially coincident MCS and WAS data, along a 350 km-long, E-W trending profile located at 38º N, crossing the basin in the North-West Iberian margin.
We apply joint refraction and reflection travel-time tomography (TT) that combines travel-times from MCS and WAS data to provide new constraints on the structure and petrological nature of basement domains along the margins. The result of this joint WAS- MCS tomography is a P-waves velocity (Vp) model of the margin that is fully consistent with the MCS image along the profile, making the geological interpretation less subjective. The processing of MCS data provides the tectonic structure and geometry of the sedimentary basins.
The results from the GoL support the existence of three geological domains that are: 1) a continental domain formed by normal faults that tilted the continental basement, 2) a ~100 km wide domain bounded by continental crust domains, characterized by a 4-5 km thick layer with high velocity and steep gradients that we interpret as a lens-shaped body of oceanic crust and 3) a thin continental crust (<4 km). This configuration implies that the continent-ocean transition (COT) occurs abruptly (<10 km along profile) at each side of the oceanic domain.
In the case of the TAP, the models show that the crustal structure is more complex, presenting sharp boundaries between five different domains at the base of the continental slope and across the J-anomaly. Thus, the profile across the TAP shows that Domain I and Domain III are made of 4-6 km thick continental crust. Domain III shows a lower crust with comparatively higher velocities possibly due to limited magmatic intrusions. Domain II, previously interpreted as oceanic crust, is shown to constitute a ~70 km wide domain of exhumed and serpentinized mantle. The westernmost 200 km of the profile include Domain IV and Domain V with a basement made of oceanic crust. The new Vp model and seismic images support that the COT is located ~300 km offshore and that occurs abruptly from 10 to 15 km wide. Based on these results, we discuss a new geodynamic scenario characterized by two main phases of crustal extension. According to the presented distribution of the basement, rifting in the TAP would have started with continental crust extension, continued with exhumation of the mantle, followed by the
formation of the oceanic crust of the J-magnetic anomaly, and continued with spreading of oceanic crust of the Cretaceous Magnetic Quiet Zone.
The interpretation of these results differs from current conceptual models of the formation of both examples of rifting systems. Its integration offers the opportunity to review the existing conceptual models related to rifted margins that involve mantle exhumation and indicate that the response of the continental lithosphere to extension processes may be more complex than previously assumed.En esta tesis doctoral, se ha realizado un estudio geofísico y geológico de dos ejemplos clásicos de márgenes continentales: el margen de la Cuenca de Liguria y el margen de la Llanura Abisal del Tajo, ubicada en el margen Oeste de Iberia. A pesar de los diversos estudios previos de estas regiones, existe un debate abierto tanto sobre su estructura cortical como sobre los procesos que operaban durante su formación. Este trabajo de tesis ha tenido como objetivos: 1) determinar la naturaleza de las rocas que forman los principales dominios geológicos de ambos márgenes, 2) definir la estructura tectónica del basamento y 3) discutir la cinemática y la interacción de mecanismos tectónicos y magmáticos involucrados en la formación de los márgenes. Para conseguir estos objetivos, se han analizado e integrado diversos datos geofísicos. Los datos principales son de sísmica de reflexión de “streamer” multicanal y de sísmica de refracción y refracción de gran ángulo marinos. También se han integrado datos batimétricos y gravimétricos. La parte metodológica más novedosa de esta tesis es la utilización de los tiempos de trayecto de fases sísmicas de datos de streamer y gran ángulo en una tomografía conjunta. Esta metodología permite determinar con más precisión que otros métodos las velocidades de las ondas sísmicas (Vp) a través del basamento a lo largo de los perfiles. El modelo resultante permite establecer la naturaleza petrológica con menos incertidumbre que los métodos más comúnmente usados. El análisis, procesamiento, modelado e interpretación de estos conjuntos de datos permite una interpretación novedosa de los aspectos relacionados con la estructura y naturaleza de la corteza, así como la discusión de nuevas propuestas para los procesos tectónicos que llevaron a la configuración actual de cada uno de los ejemplos de márgenes continentales. La interpretación desarrollada difiere en gran medida de modelos previos en cuanto a la formación de ambos sistemas de rifting. Por ello, proponemos que su integración ofrece la oportunidad de revisar modelos conceptuales existentes en la literatura. En particular, los resultados muestran que la respuesta de la litosfera continental a los procesos de extensión puede ser más compleja de lo que se suponía hasta ahora.

Full textAbstract:
This thesis presents a comparative species history of the Grey Wolf (Canis lupus) and the Wild Boar (Sus scrofa) in Liguria, northwest Italy, from the sixteenth century to the modem day. It makes use of approaches drawn from history, geography and archaeology and draws on the traditions of micro-history. The archives used are diverse, including commune statutes, financial accounts, cronaci and annali of local priests and lawyers, death registers, hunting records, legislation and images and culinary manuals. A most important element is the use of oral histories. This thesis examines the percept ions and attitudes of human communities towards wolves and wild boar and the role that these played in the disappearance and subsequent reappearance of the species in the region. Through examining these on a micro-geohistorical frame of focus, this thesis seeks to identify and extrapolate elements of continuity and change during the period in question, and considers the implications that these perceptions and attitudes play in terms of the current management and conservation of the species in twenty-first century Liguria.

Full textAbstract:
The deposits of four caves in western Liguria have been investigated, in particular Tana di Badalucco (Imperia), Arma degli Zerbi (Savona), Caverna delle Fate (Savona) and Arma delle Manie (Savona). These are caves already extensively studied in the past, but exclusively from an archaeological point of view. In this case, the study involved the application of different techniques aimed at the final objective of obtaining a paleoclimatic and paleoenvironmental reconstruction for this study area. The techniques used were different, starting from routine bulk analyses, passing from XRD analysis, and ending, and focusing in particular, on the use of the micromorphological technique. This allowed us to identify, in detail, the more or less significant changes that occurred in this region during the last glacial period and the Holocene, and therefore the alternation of more or less cold and more or less humid conditions of the last 120 kyr.

Il presente elaborato vuole indagare la forza promozionale dei livelli geografici del brand turistico. Dopo l’inquadramento teorico delle definizioni di destinazione, brand e livello geografico, viene intrapresa una prima strada in cui si analizza il cosiddetto “effetto Paese” per la promozione turistica delle destinazioni nazionali che viene abbandonata in favore di una ricerca sull’immagine turistica percepita della Liguria e delle località di Genova e Sanremo. Quello che si vuole indagare tramite il questionario distribuito online a visitatori, visitatori potenziali e residenti è l’identità della regione e la sua percezione e se nell’immaginario collettivo siano più presenti le singole destinazioni più che il livello geografico superiore. Per la stesura del questionario viene utilizzata la tecnica dell’elicitazione fotografica grazie alla quale l’immagine percepita viene studiata utilizzando lo stimolo visivo.
In seguito viene analizzato quello che è il brand #lamialiguria, come nasce, da cosa è ispirato, e la campagna promozionale “Liguria sopra le righe” a cui hanno aderito più di 70 comuni liguri.
Alla fine della trattazione si vuole rispondere alla seguente research question: “Quando si affronta la questione della promozione turistica è utile mettere in atto strategie su più livelli geografici?”

Full textAbstract:
La tesi ha come oggetto lo studio monografico di una famiglia di pittori di origine fiorentina attiva in Liguria, in particolare nel Ponente, entro una vasta area compresa tra Genova e Ventimiglia, con alcune puntate nel Basso Piemonte occidentale, a partire dall’inizio del Cinquecento fino al primo quarto del secolo successivo. L’attenzione si è focalizzata sulla ricostruzione delle vicende biografiche, operata attraverso il sondaggio e la rilettura delle fonti d’archivio, del capostipite Raffaello De Rossi (notizie 1510-1572), attestato per la prima volta a Genova nel 1514 ma già attivo nel finalese quattro anni prima, del figlio Giulio (notizie 1551-1591) e del nipote Orazio (notizie dal 1581-Genova 1626). Parimenti si è proceduto a una riconsiderazione critica della loro attività alla luce delle testimonianze figurative ad oggi conservatesi. L’obbiettivo è quello di riabilitare una bottega di artisti contraddistinta da una vicenda critica articolata e frammentata (per molto tempo la loro eterogenea produzione è confluita sotto il generico pseudonimo di “Pancalino” prima di essergli correttamente restituita solo all’inizio degli anni Novanta del secolo scorso), rintracciando le matrici culturali del loro linguaggio e i loro rapporti col panorama artistico locale. Il lavoro si correda di alcune appendici, quali un aggiornato catalogo ragionato del corpus delle opere, un regesto cronologico e una sezione dedicata alla trascrizione degli atti d’arte. A completare significativamente il senso e le intenzioni della ricerca è chiamato l’apparato iconografico, parzialmente frutto di una campagna svolta per l’occasione che ha prodotto, in alcuni casi per la prima volta, documentazione fotografica di alta qualità in relazione ad un patrimonio altrimenti non facilmente fruibileThe thesis aims to study a family of painters of Florentine origin active in Liguria, in particular in the western coast, within a large area between Genoa and Ventimiglia (with some episodes in Piedmont), ranging from the beginning of the sixteenth century until to the first quarter of the seventeenth century. The focus is mainly put on the reconstruction of the biographical events, carried out through the reading of the archival sources, of the progenitor Raffaello De Rossi (recorded from 1510 to 1572), of his son Giulio (recorded from 1551 to 1591) and of his nephew Orazio (recorded from 1581 to 1626). Likewise, a critical reconsideration of their activity was conducted in the light of the figurative traces still preserved today. The goal is to attempt a reconstruction of a workshop of artists, characterized by an articulated and fragmented critical historiography (for a long time their heterogeneous production had been labelled with a pseudonym, the "Pancalino", to be correctly reassigned to them only at the beginning of the nineties of the past century), by tracing the cultural references of their style and their relationships with the local artistic environment. The research is enriched by an updated catalogue of the corpus of works, a chronological register and a documentary appendix. Not least, is the iconographic apparatus, partly as the result of a photographic campaign carried out for the occasion which produced, in some cases for the first time, high-quality images of the studied paintings.

Full textAbstract:
Aujourd'hui, la situation des langues régionales soulève de nombreuses questions, notamment en ce qui concerne les zones linguistiques charnières et de transition, comme le département des Alpes Maritimes. Zone de contact de langue entre le français, l’italien, et plus précisément le ligure – présent jusqu’à Menton, où il est en transition avec le provençal – la vallée de la Roya est un territoire plurilinguistique et pluriculturel complexe. Du côté français, notre étude porte sur les parlers des villages de Tende, la Brigue et Breil-sur-Roya (du nord au sud de la haute vallée de la Roya française), sur lesquels ont travaillé de manière plus importante les linguistes Werner Forner et Jean-Philippe Dalbera. Du côté italien, j’ai orienté mes recherches sur les villes de la basse vallée de la Roya, Sanremo et Vintimille, au Sud de la Ligurie occidentale, et sur les villages de Triora et Pigna, plus au nord.Au-delà des conflits d’identités et de l’urgence de sauvegarder les langues par leur transmission dans les associations, l’un des problèmes les plus épineux reste la classification linguistique des parlers locaux. En effet, si le territoire de la vallée est officiellement considéré zone occitane, les linguistes y opposent fermement une appartenance ligure-alpine. Dans une orientation sociolinguistique, notre propos sera de dépasser les considérations purement linguistiques pour faire émerger les représentations des locuteurs quant à leur culture et à leur parler.En ce qui concerne nos recherches sur le terrain, elles relèvent de « l’étude des pratiques langagières authentiques en contexte social relève de la sociolinguistique, au sens large » Gadet (2003 : 5) dans un cadre épistémologique socioconstructiviste de la pensée complexe et théorique de l’ethno-sociolinguistique (Calvet, 1993, Blanchet, 2000). Nos recherches se situent dans le domaine des langues en contact et s’orientent vers une sociolinguistique variationniste (Labov, 1976) et interactionnelle (Hymes, 1982 ; Gumperz,1989 a et b), avec l’étude de l’hétérogénéité des systèmes linguistiques et de l’hétérogénéité linguistique des groupes sociaux de notre enquête. Nous interrogeons également dans ce cadre la question des phénomènes de domination (Marcellesi et Gardin 1974, Blanchet 2018, Colonna 2020)Today, the situation of regional languages raises many questions, particularly with regard to the hinge and transition linguistic zones, such as the Alpes Maritimes department. A language contact zone between French, Italian, and more precisely Ligurian - present as far as Menton, where it is in transition with Provençal - the Roya valley is a complex plurilingual and pluricultural territory.On the French side, our study focuses on the languages of the villages of Tende, La Brigue and Breil-sur-Roya (from the north to the south of the upper valley of the French Roya), on which the linguists Werner Forner and Jean-Philippe Dalbera have worked extensively. On the Italian side, I focused my research on the towns of the lower Roya valley, Sanremo and Ventimiglia, in the south of Western Liguria, and on the villages of Triora and Pigna, further north.Beyond the conflicts of identities and the urgency of safeguarding languages through their transmission in associations, one of the thorniest problems remains the linguistic classification of local languages. Although the territory of the valley is officially considered to be an Occitan area, linguists firmly oppose Ligurian-Alpine membership. From a sociolinguistic point of view, our aim will be to go beyond purely linguistic considerations to bring out the speakers' representations of their culture and of speaking to them.As far as our fieldwork is concerned, it is part of "the study of authentic language practices in a social context is a matter of sociolinguistics, in the broadest sense" Gadet (2003: 5) within a socioconstructivist epistemological framework of complex thinking and ethno-sociolinguistics theory (Calvet, 1993, Blanchet, 2000). Our research is situated in the field of languages in contact and is oriented towards a variationist (Labov, 1976) and interactional (Hymes, 1982; Gumperz, 1989 a and b) sociolinguistics, with the study of the heterogeneity of the linguistic systems and the linguistic heterogeneity of the social groups in our survey. We also interrogate in this framework the question of domination phenomena (Marcellesi and Gardin 1974, Blanchet 2018, Colonna 2020)

Full textAbstract:
Cette thèse est consacrée à l’étude de l’œuvre et de la poétique de Francesco Biamonti (1928-2001). Elle propose un parcours critique qui montre les liens entre l’écriture de l’auteur, aussi bien dans ses thématiques que dans ses choix stylistiques, et l’expérience culturelle qui la sous-tend. Les romans biamontiens apparaissent comme une tentative d’exprimer sous forme artistique une vision personnelle du monde et de l’homme, que l’écrivain italien élabora en autodidacte pendant sa vie. Il s’agit d’une vision qui ne peut ne pas tenir compte de la réflexion sur le territoire du Ponant ligurien, représenté par Biamonti dans ses transformations du XXe siècle et dans son actualité. Ainsi, la juxtaposition des termes territoire et existence dans le titre suggère une première clef de lecture de cette étude.Cette thèse s’articule en trois grandes parties. Dans la première partie, l’étude de l’espace romanesque favorise l’analyse de la vision biamontienne de l’histoire méditerranéenne et européenne, et montre les mécanismes de transfiguration et les processus mythopoïétiques caractérisant la représentation du Ponant ligurien et de l’« ailleurs » français dans les romans. La deuxième partie porte sur l’analyse des personnages et propose une interprétation de la conception biamontienne de la réalité humaine sur la base des théories existentialistes et phénoménologiques. Enfin, la dernière partie explore l’idée de création artistique et souligne certaines caractéristiques de la prose biamontienne et de son lyrisme dans une perspective aussi bien textuelle que théoriqueThe PhD Thesis is devoted to the study of the work and the poetics of Francesco Biamonti (1928-2001). It proposes a critical analysis showing the connections between the writing of the author, in both its themes and its stylistic choices, and its underlying cultural influences. Biamonti’s novels appear as an attempt to express his personal vision of the world and the human condition, which the Italian writer developed as autodidact all along his life. Framing this vision cannot ignore the considerations of the author about the Ligurian west territory, represented through its twentieth century transformations and its contemporary topics. Thus, the juxtaposition of the words territory and existence in the title suggests the first key to read this work by.The PhD Thesis is articulated in three main parts. The first part, through the study of the narrative space, analyses Biamonti’s reflections on the Mediterranean and European history; moreover, it contains the literary mechanisms and the mythopoietic processes characterizing the representation of the Ligurian territory and the French “Elsewhere” in the novels of the author. The second part is concerned with the study of the characters and, in light of a series of philosophical readings, it examines Biamonti’s conception of the human reality and existence. The third and final part explores the idea of artistic creation and highlights specific characteristics

Il faut contextualiser l’expression «gens ordinaires» soit du point de vue historique, soit sociale et culturelle: en examinant les caractéristiques des sujets ligures impliqués dans l’exil antifasciste, dans leur territoire d’origine, cette catégorie devient un instrument précieux au fin de sonder de l’intérieur les dynamiques de network de la société. L’étude régionale adoptée permette de suivre des réseaux transnationaux liés à une très remarquable identité de village et/ou de parti politique, ce qui représente une typique modalité migratoire transalpine qui ne s’organisait pas selon des «Little Italies», mais plutôt selon des «petits villages italiens»This research focus on antifascist migration from Liguria to France, explaining how it has been mostly toward the South-East and Paris. It doesn't target general studies: its focal point, indeed, is on common people and migrant families’ experience. The “Common people” expression must be historically, socially and culturally contextualized. By examining the topics of Ligurian subjects involved in the Interwar period exile, identified in their own original territory, the common people category becomes a precious instrument to evaluate society network dynamics from inside.The regional study allows to follow transnational networks with a strong native town or party identity, a typical Italian migration modality in France, which organized itself in “petits villages italiens” rather than the American model of “Little Italies”

Full textAbstract:
Nell’autunno del 2011 due eventi meteorologici estremi caratterizzati da intense precipitazioni hanno interessato la Liguria. Nella giornata del 25 ottobre si è verificato sul Levante ligure un evento alluvionale di rilevante entità, determinato dalla formazione di un intenso sistema convettivo che ha coinvolto l’area compresa tra il Tigullio, le Cinque Terre ed il bacino del Magra.
Un altro episodio di forte maltempo si è verificato tra il 3 e il 9 novembre 2011, e in particolare il forte sistema convettivo che ha interessato Genova la mattina del 4
novembre, in cui avvenne l’esondazione in alcuni punti del torrente Bisagno e del rio Fereggiano. Tuttavia, nel corso del lungo periodo perturbato si sono registrati vari episodi di esondazione, localizzati principalmente in zone golenali agricole, anche sui versanti padani della regione, oltre a numerosi casi di smottamenti e frane.
I casi sopra citati sono stati studiati facendo innanzitutto un’accurata analisi meteorologica a scala sinottica e alla mesoscala, esaminando in particolar modo i
meccanismi che hanno portato l’innesco dei due sistemi temporaleschi.
In secondo luogo, utilizzando anche dati osservativi disponibili, si è voluto mettere in evidenza la reale e significativa evoluzione nel tempo e nello spazio dei dati
pluviometrici delle stazioni al suolo, e dei parametri fisici più importanti, come ad esempio la direzione e l’intensità del vento.
Infine, utilizzando simulazioni numeriche dei modelli sviluppati all’ISAC-CNR di Bologna (BOLAM e MOLOCH), ci si è posti l’obiettivo di verificare la loro sensibilità alla risoluzione e ad altri aspetti numerici e fisici, in particolare per quanto riguarda i dati relativi alla precipitazione. I modelli, oltre a riprodurre la dinamica degli eventi in maniera fisicamente coerente anche se non del tutto accurata, sono stati utilizzati, previo confronto con le osservazioni, per verificare alcune ipotesi formulate relative ai processi fisici responsabili dell’intensità della precipitazione, come ad esempio la presenza del flusso (outflow) di aria fredda proveniente dalla cold pool in relazione con le correnti caldo-umide negli strati più bassi (Low Level Jet, LLJ), e la formazione di una zona di convergenza nella quale è più alta la probabilità che si sviluppino sistemi convettivi organizzati.

Full textAbstract:
Landslides are frequently responsible for considerable huge economic losses and casualties in mountainous regions especially nowadays as development expands into unstable hillslope areas under the pressures of increasing population size and urbanization (Di Martire et al. 2012). People are not the only vulnerable targets of landslides. Indeed, mass movements can easily lay waste to everything in their path, threatening human properties, infrastructures and natural environments.
Italy is severely affected by landslide phenomena and it is one of the most European countries affected by this kind of phenomena. In this framework, Italy is particularly concerned with forecasting landslide effects (Calcaterra et al. 2003b), in compliance with the National Law n. 267/98, enforced after the devastating landslide event of Sarno (Campania, Southern Italy). According to the latest Superior Institute for the Environmental Protection and Research (ISPRA, 2018) report on "hydrogeological instability" of 2018, it emerges that the population exposed to landslides risk is more than 5 million and in particular almost half-million falls into very high hazard zones. The slope stability can be compromised by both natural and human-caused changes in the environment. The main reasons can be summarised into heavy rainfalls, earthquakes, rapid snow-melts, slope cut due to erosions, and variation in groundwater levels for the natural cases whilst slopes steepening through construction, quarrying, building of houses, and farming along the foot of mountainous zone correspond to the human component.
This Ph.D. thesis was carried out in the Liguria region, inside the Cinque Terre National Park. This area was chosen due to its abundance of different types of landslides and its geological, geomorphological and urban characteristics. The Cinque Terre area can be considered as one of the most representative examples of human-modified landscape. Starting from the early centuries of the Middle Ages, local farmers have almost completely modified the original slope topography through the construction of dry-stone walls, creating an outstanding terraced coastal landscape (Terranova 1984, 1989; Terranova et al. 2006; Brandolini 2017). This territory is extremely dynamic since it is characterized by a complex geological and geomorphological setting, where many surficial geomorphic processes coexist, along with peculiar weather conditions (Cevasco et al. 2015). For this reason, part of this research focused on analyzing the disaster that hit the Cinque Terre on October, 25th, 2011. Multiple landslides took place in this occasion, triggering almost simultaneously hundreds of shallow landslides in the time-lapse of 5-6 hours, causing 13 victims, and severe structural and economic damage (Cevasco et al. 2012; D’Amato Avanzi et al. 2013). Moreover, this artificial landscape experienced important land-use changes over the last century (Cevasco et al. 2014; Brandolini 2017), mostly related to the abandonment of agricultural activity. It is known that terraced landscapes, when no longer properly maintained, become more prone to erosion processes and mass movements (Lesschen et al. 2008; Brandolini et al. 2018a; Moreno-de-las-Heras et al. 2019; Seeger et al. 2019).
Within the context of slope instability, the international community has been focusing for the last decade on recognising the landslide susceptibility/hazard of a given area of interest. Landslide susceptibility predicts "where" landslides are likely to occur, whereas, landslide hazard evaluates future spatial and temporal mass movement occurrence (Guzzetti et al., 1999). Although both definitions are incorrectly used as interchangeable. Such a recognition phase becomes crucial for land use planning activities aimed at the protection of people and infrastructures. In fact, only with proper risk assessment governments, regional institutions, and municipalities can prepare the appropriate countermeasures at different scales. Thus, landslide susceptibility is the keystone of a long chain of procedures that are actively implemented to manage landslide risk at all levels, especially in vulnerable areas such as Liguria. The methods implemented in this dissertation have the overall objective of evaluating advanced algorithms for modeling landslide susceptibility.
The thesis has been structured in six chapters. The first chapter introduces and motivates the work conducted in the three years of the project by including information about the research objectives. The second chapter gives the basic concepts related to landslides, definition, classification and causes, landslide inventory, along with the derived products: susceptibility, hazard and risk zoning, with particular attention to the evaluation of landslide susceptibility. The objective of the third chapter is to define the different methodologies, algorithms and procedures applied during the research activity. The fourth chapter deals with the geographical, geological and geomorphological features of the study area. The fifth chapter provides information about the results of the applied methodologies to the study area: Machine Learning algorithms, runout method and Bayesian approach. Furthermore, critical discussions on the outcomes obtained are also described. The sixth chapter deals with the discussions and the conclusions of this research, critically analysing the role of such work in the general panorama of the scientific community and illustrating the possible future perspectives.

Full textAbstract:
The early Neolithic of the western Mediterranean is represented by a polymorphic set of cultural expressions, traditionally defined by the presence of impressed wares, that developed during the sixth millennium BCE. By tracing the morphological and decorative variability of these ceramic productions, it was possible to outline a model of arrhythmic progression of the Neolithic package diffusion, from east to west, characterized by a continuous renewal of its techno-cultural components.
Within this context, from the beginning of the sixth millennium BCE, Liguria is a particularly representative space of the social and cultural transformations that took place in the western Mediterranean and represents a privileged area for the untangling of the mechanisms of Neolithic diffusion in this area. This research focused on the technological analysis of ceramic production in order to decode the techno-economic systems of the Neolithic groups, through an integrated study, which was structured in two progressive and complementary levels, from infra-site to a regional scale.
Recent excavations at the Arene Candide cave (1997-2012) documented in detail a clear stratigraphic sequence related to the early Neolithic phases, providing new and consistent proxy data. The technological analysis of the ceramic assemblage resulting from these researches allowed for the reconstruction of the pottery production system in relation to the stratigraphic and chronological articulation, highlighting an evolution of technical and stylistic behaviours during the sixth millennium BCE. This led to the elaboration of a diachronic model, articulated in different chrono-cultural horizons, each characterized by specific techno-stylistic markers. The systematic revision of the pottery from the contemporary sites of the region, mainly distributed between the Finalese region and Val Pennavaira, and often neglected due to their absent or unreliable contextual documentation, was also implemented. This revision allowed for the clarification of the chronological and cultural attribution of these ceramic sets, providing new elements for a diachronic reconstruction of settlement dynamics, as well as of the organization and management of the territory during the sixth millennium BCE, and finally revealed cultural interactions with the western Mediterranean basin.
In general, the results obtained by this study increase, both quantitatively and qualitatively, the data relating to the early Neolithic stages of the region, unlocking the informative potential of a holistic approach to the analysis of the ceramic document, even when applied to remarkably fragmentary materials. These new results contribute to the ongoing debate on the complex phenomenon of the neolithization of the western Mediterranean.

Full textAbstract:
L'Italia è spesso sede di eventi d'intensa precipitazione, frequentemente associati ad alluvioni con conseguente perdita di vite umane e gravi danni economici. È quindi di fondamentale importanza poter prevedere questi eventi con un adeguato anticipo. Allo stato attuale, i modelli meteorologici non permettono sempre di raggiungere tale obbiettivo e, di conseguenza, è in atto un'intensa attività di ricerca al fine di di renderne più accurata la previsione, sia attraverso il miglioramento dei modelli stessi, sia sviluppando l'assimilazione dati, la quale riduce l'incertezza della condizione iniziale da cui parte la previsione.
All'interno di questo contesto, la tesi si prefigge l'obiettivo di studiare gli effetti dell'assimilazione di dati di precipitazione, effettuata mediante uno schema di nudging, nel modello non idrostatico MOLOCH. Al fine di ottimizzare lo schema e di valutarne l'impatto, sono stati simulati tutti gli eventi di maltempo di ottobre e novembre del 2014 che hanno interessato la Liguria, area frequentemente soggetta ad alluvioni.
Dalla sistematica verifica dei risultati, effettuata sia qualitativamente che mediante numerosi metodi statistici (tra cui la tecnica SAL basata sull'individuazione dei nuclei di precipitazione), si riscontra un generale miglioramento della previsione della precipitazione anche se limitato alle prime ore dopo la fine del periodo di assimilazione. L'impatto dello schema di nudging varia a seconda dell'evento e, in particolare, si osserva una certa correlazione tra il miglioramento ottenuto e la tipologia di evento, come descritto dalla teoria dell'equilibrio convettivo e come riportato in alcuni studi analoghi recentemente comparsi in letteratura. La ricaduta del miglioramento della previsione meteorologica è stata valutata anche in termini di impatti al suolo accoppiando il modello meteorologico con il modello idrologico utilizzato dal Centro Funzionale della Regione Liguria, con risultati abbastanza positivi.

Le présent travail se propose de reconstruire la genèse et l'évolution de la frontière entre Provence et Ligurie et son impact sur les sociétés locales. L'enquête a choisi, pour zone spécifique, la vallée de la Nervia. Comprise entre les montagnes du Ponant ligure et de la région de Nice, elle a seule constitué pendant plus de cinq siècles (1262-1796) une marche entre deux entités étatiques souvent en conflit : la République de Gênes à l'est, la Provence angevine puis les domaines savoyards à l'ouest. La recherche n'a pas mobilisé moins d'un millier de documents répartis entre les archives de trois pays européens (France, Italie, Monaco). Pour le Moyen Âge, elle a mis d'abord en lumière l'importance tant économique que stratégique de la vallée. Elle a concurremment retracé les politiques menées dans la contrée par Gênes, par la Provence et par les Savoie en matière de communications routières, de production et d'échanges, comme de peuplement. Elle a autant considéré les relations complexes entre seigneurs et communautés. À cette première partie succède une analyse des sociétés locales au seizième siècle. Une attention particulière est accordée aux Doria de Dolceacqua et à leur rôle dans le développement « proto-industriel » du territoire, en tant que gros entrepreneurs dans les secteurs du vin, de l'huile d'olive et du papier. La diffusion de la Réforme dans les villages gouvernés par le duc de Savoie et le renouveau catholique post-tridentin se sont révélés comme d'autres thèmes majeurs. La dernière partie de la thèse se propose de déterminer jusqu'à quel point la présence d'une frontière influa sur la vie et sur les activités quotidiennes des habitantsThis work aims to reconstruct the genesis and the evolution of the frontier between Liguria and Provence and its impact on local societies. The specific area of research is the Nervia Valley: the only, among the valleys of western Liguria and the region of Nice, to have constituted for more than five centuries (1262-1796) a frontier between two countries often in conflict, the Republic of Genoa in the east and Angevin Provence (later Savoy) in the west. Based on a thousand documents preserved at the archives of three European states (France, Italy and Monaco), the study firstly highlights both the economic and strategic importance of the Nervia Valley; the road network, economic and settlement policies pursued in this area by Genoa, Provence and the House of Savoy; the complex relations between Lords and communities. The second part of the work investigates the local societies in the Sixteenth century. Special attention is devoted to the Doria of Dolceacqua and to their role in the industrial development of the territory as wine, olive oil and paper entrepreneurs; to the diffusion of the ideas fostered by the Reformation in the villages governed by the duke of Savoy; and to the post-Tridentine Catholic renewal. The final part tries to assess to what degree the presence of a frontier influenced the life and daily activities of the inhabitants

Full textAbstract:
Il progetto di dottorato è stato principalmente focalizzato sull’implementazione delle tecniche di riproduzione controllata nel genere Patella. Le specie oggetto di studio sono state P. caerulea e più in particolare P. ferruginea, specie protetta e in via di estinzione, il cui ripopolamento è oggetto del progetto europeo ReLife (LIFE15 NAT/IT/000771).
Essendo P. ferruginea una specie protetta, inizialmente abbiamo preferito testare i trattamenti di induzione non letale su una specie cogenerica, P. caerulea, comune e abbondante lungo le coste italiane. I vari trattamenti testati hanno dato ottimi risultati, e il trattamento del “bubbling” è risultato il migliore, sia in termini di tempo di risposta alla stimolazione degli esemplari, sia perché si tratta di un metodo poco costoso e facilmente ripetibile. È stato possibile stilare un protocollo di spawning non letale, ed effettuare una fecondazione artificiale con successivo sviluppo larvale e insediamento dei giovanili (Ferranti et al., 2018).
Inoltre, sono stati condotti dei monitoraggi lungo la costa ligure, che hanno permesso di riportare la presenza di esemplari di P. ferruginea, considerata estinta lungo queste coste (Espinosa et al., 2014). La distribuzione di P. ferruginea, lungo le coste liguri, è estremamente scarsa e frammentata, infatti la specie è stata rinvenuta come esemplari isolati o piccoli gruppi, come nell'AMP delle Cinque Terre. Questi ritrovamenti hanno però permesso di ampliare la mappatura della presenza di P. ferruginea lungo le coste del Mediterraneo (Ferranti et al., 2019).
Inoltre, per comprendere meglio il ciclo riproduttivo e i tempi di rilascio dei gameti in P. ferruginea alle nostre latitudini, abbiamo posizionato degli esemplari in mare per la maturazione in condizioni naturali, fino all’inizio del periodo riproduttivo. Gli esemplari successivamente sono stati sottoposti a biopsia della gonade sia prima di essere messi in mare per determinare il sesso (Guallart et al., 2013a), che all'inizio del periodo riproduttivo previsto per comprendere lo stadio di maturazione. L’osservazione del materiale ottenuto tramite biopsia ha permesso di determinare che gli esemplari avevano raggiunto la maturazione gonadica e che uno di loro aveva effettuato il cambio di sesso, evento noto in letteratura, ma osservato qui per la prima volta alla latitudine del Mediterraneo nord-occidentale (Ferranti et al., 2021). Tali risultati implicano che la specie può completare il suo ciclo riproduttivo lungo le coste liguri.
Sempre al fine di comprendere meglio i tempi di maturazione delle gonadi, abbiamo applicato le tecniche della Risonanza Magnetica su esemplari di patelle. La Risonanza Magnetica, attraverso un approccio non invasivo, ha permesso di osservare lo spessore della gonade e anche di capire se un esemplare avesse rilasciato o meno gameti, al fine di applicare eventualmente tecniche di stimolazione al rilascio dei gameti solo al momento giusto. I risultati indicano che la risonanza magnetica può essere molto utile come strumento aggiuntivo, sia per valutare la maturità sessuale di P. ferruginea, che per ridurre al minimo il numero di prove di induzione per ogni esemplare, e di conseguenza lo stress (Guallart et al., 2020).
Ancora più rilevante è l'aver fornito l’evidenza, per la prima volta, che l’emissione delle uova può essere indotta in P. ferruginea e dimostrare che è possibile ottenere giovanili, in condizioni controllate, attraverso metodi non invasivi. Questi risultati hanno permesso di elaborare un protocollo preliminare sull'induzione all’emissione spontanea dei gameti da parte di P. ferruginea, senza sacrificare i riproduttori di una specie protetta. Inoltre, questo ci ha permesso di effettuare una fecondazione artificiale che ha portato allo sviluppo, insediamento, metamorfosi e crescita larvale di un numero piuttosto elevato di individui giovanili di P. ferruginea (Ferranti et al., in prep.).
Di conseguenza, sapendo che la specie è presente lungo la costa ligure, che riesce a raggiungere la maturità anche a queste latitudini e che è possibile riprodurre P. ferruginea in condizioni controllate fino allo stadio giovanile, possiamo affermare che esiste la possibilità di ripopolamento e reintroduzione in ambiente naturale di esemplari di P. ferruginea, recuperando questa specie nell’area in oggetto, come previsto dal progetto ReLife.
Inoltre, la reintroduzione realizzata da esemplari ottenuti mediante tecniche di acquacoltura, senza influenzare sostanzialmente le popolazioni donatrici, è anche in accordo con la strategia spagnola per la conservazione della specie (MMAMRM, 2008), e in generale, le azioni di ripopolamento attraverso la riproduzione controllata, potrebbero consentire in futuro di ripopolare altre aree costiere, dove le popolazioni di P. ferruginea sono scomparse e/o in regressione, per un recupero della specie a livello globale.The PhD project was mainly focused on the implementation of controlled reproduction techniques in the Patella genus. The species considered were P. caerulea and more particularly P. ferruginea, a protected and endangered species, whose repopulation is the subject of the European ReLife project (LIFE15 NAT/IT/000771). Being P. ferruginea a protected species, we initially preferred to test the non-lethal induction treatments on a cogeneric species, P. caerulea, common and abundant along the Italian coasts. The various treatments tested have provided excellent results, and the “bubbling” treatment was the best, both in terms of time of response to stimulation of the specimens and of replicability and ease of use. The results obtained made it possible to draw up a non-lethal spawning protocol, and to carry out artificial fertilization with subsequent larval development and settlement of the juveniles (Ferranti et al., 2018). In addition, monitoring was carried out along the Ligurian coast, which allowed reporting the presence of P. ferruginea, considered extinct along these coasts (Espinosa et al., 2014). P. ferruginea distribution, along the Ligurian coasts, is extremely scarce and fragmented; in fact the species has been found as isolated specimens or small groups, such as in the Cinque Terre MPA. However, these findings permitted to expand the mapping of the presence of P. ferruginea along the Mediterranean coasts (Ferranti et al., 2019). Furthermore, to better understand the reproductive cycle and the timing of P. ferruginea natural spawning at our latitudes, we placed specimens at sea for maturation in natural conditions, up to the beginning of the expected reproductive period. Specimens were later subjected to a biopsy of the gonad, both before being placed in the sea to determine sex (Guallart et al., 2013a), and at the beginning of the expected reproductive period to understand the stage of maturation. The observation of the material obtained through biopsy made it possible to determine that the specimens had reached gonadal maturation and that one of them had performed sex change, an event known in the literature, but observed here for the first time at the north-western Mediterranean latitude (Ferranti et al., 2021). This implies that the species can complete its reproductive cycle along the Ligurian coasts. Always in view of a better understanding of the timing of gonad maturation, we applied the Magnetic Resonance Imaging (MRI) techniques on limpets. MRI, through a non-invasive approach, allowed to observe the thickness of the gonad and also to understand whether or not a specimen had released gametes, in order to eventually apply stimulation techniques to spawning only at the right time, reducing stress on specimens. The results indicated that MRI can be very useful as an additional tool, both in evaluating the sexual maturity of P. ferruginea and in minimizing the number of induction trials for each specimen, and consequently the stress (Guallart et al., 2020). Even more relevant is having provided evidence, for the first time, that spawning can be induced in P. ferruginea and demonstrated the feasibility of obtaining juveniles, under controlled conditions through low-invasive methods. These results allowed drawing up a preliminary protocol on the induction of spawning of P. ferruginea, which allows for the spontaneous release of gametes, without sacrificing the broodstock of a protected species. Furthermore, this allowed us to carry out an artificial fertilization that led to larval development, settlement, metamorphosis and growth of a pretty large number of P. ferruginea juveniles (Ferranti et al., in prep.). Consequently, knowing that the species is present along the Ligurian coast, that it manages to reach maturity even at these latitudes, and that it is possible to reproduce P. ferruginea under controlled conditions until it reaches the juvenile stage, we provide evidence of the feasibility of P. ferruginea restocking and reintroduction in the natural environment, recovering this species in this area, as expected from the ReLife project. Moreover, the reintroduction made from specimens obtained through aquaculture techniques, without substantially affecting donor populations, is also in accordance with the Spanish strategy for the conservation of the species (MMAMRM, 2008), and generally, repopulation actions through controlled reproduction, could allow in the future to repopulate other coastal areas, where populations of P. ferruginea are disappeared and/or in regression, for the recovery of the species at a global level.

The effect of severe Herpes Zoster (HZ) on chronic diseases is a component of the real burden of this vaccine-preventable disease that is not commonly considered. A retrospective cohort study was conducted to assess the health burden of severe HZ in adults ≥50 years residing in Liguria Region from 2015 to 2017. Subjects hospitalized with and without HZ were matched (1:6 ratio). 437 subjects in the HZ cohort and 2622 subjects in the non-HZ cohort were enrolled. Previous immunodeficiency, autoimmune, and rare diseases are identified as main chronic conditions related to HZ hospitalization. Higher incidences of autoimmune (1.4% vs. 0.22%, p = 0.002) and gastrointestinal (7.04% vs. 3.62%, p = 0.015) diseases after hospitalization were observed in the HZ cohort compared to the non-HZ cohort. Significantly higher incidences were found after hospitalization versus the previous period for cardiovascular diseases (11.17% vs. 2.09%, p < 0.001), cerebral vasculopathy (6.13% vs. 0.60%, p < 0.001), non-arrhythmic myocardiopathy (4.31% vs. 0.59%, p = 0.002), and neuropathy (2.62% vs. 0.56%, p = 0.033). The HZ cohort showed a relative risk 10-fold higher for cerebral vasculopathy, 5-fold higher for cardiovascular diseases, and 7-fold higher for non-arrhythmic myocardiopathy. HZ causes a substantial impact on the chronic conditions. These data could suggest an implementation of HZ vaccination programs in the elderly and in high-risk groups.

Full textAbstract:
The future climate change represents the biggest challenge for plant and animal species. The scenarios forecasted by the IPCC predict a global increase in temperatures and regional changes in rainfall during this century. Therefore, studying the relationship between climate and several traits of species is crucial in our understanding of the effects that future changes may have on plants. Species growing along a wide environmental gradient are a suitable study model to verify the relationship between intraspecific variability and both current and future climate. The aim of my PhD project is to analyse the relationship between environmental variability and variation in morphological traits, germination capacity and genetic structure of Lilium pomponium, using a multidisciplinary approach. The results of this study may enhance our understanding about the possible responses of this threatened species to environmental changes. Lilium pomponium is an endemism of the Ligurian and Maritime Alps spanning along a wide altitudinal gradient (100 and 2000 m a.s.l.), ranging from a Mediterranean to a subalpine climate. Our results show that the populations exposed to different environmental pressures have variations in floral characteristics, these variations likely play an important role in reducing among-populations variability in reproductive output. Germination tests show that the increase in temperature may negatively affect seeds germination capacity. Nevertheless, projections of thermal requirement for seed germination under future climatic conditions suggest that populations will probably respond to future temperature increase shifting their germination phenology. Moreover, in the future the species may find suitable ecological conditions for seed germination in new areas at higher altitudes. Finally, genetic analysis suggests that there is no clear pattern of diversity and differentiation between populations, which may be related to the topographic complexity of the areas and to the biogeographical history of the species. Overall, the results obtained suggest that high among-populations variability found in L. pomponium may be a bet-hedging strategy to cope with unpredictable environmental conditions occurring in Mediterranean climate and that it might also represent a successful strategy to face the future environmental change.

L'étude des caractéristiques hydrodynamiques des courants gravitaires permet de préciser nos connaissances sur leur mécanisme de formation. Les courants gravitaires peuvent être initiés par des déstabilisations dans le canyon ou par le plongement en mer de l'eau turbide du fleuve (courant de turbidité hyperpycnal). Ces derniers peuvent être générés lorsque le débit liquide du fleuve franchit un seuil de 306 m3.s-1 à l'embouchure, et à condition que la crue soit étendue à l'ensemble du réseau hydrographique. L'étude combinée des mesures sur les deux années et des faciès sédimentaires dans les dépôts du siècle dernier souligne la prépondérance des courants de turbidité hyperpycnaux, qui représentent 80 % des écoulements gravitaires. De plus, cette étude combinée montre que les écoulements de faible magnitude (résultant de petites instabilités ou de crues annuelles du fleuve) s'arrêtent généralement au débouché de la vallée supérieure et ne déposent du sédiment que sur une terrasse située à 70 m au dessus du fond de la vallée. Les courants gravitaires de grande magnitude (résultant de larges instabilités ou de crues majeures du fleuve) sont fortement érosifs dans la partie du système située avant le pied de pente, et déposent des séquences sédimentaires sur les terrasses, la levée, et localement dans le chenal. Le cadre chrono-stratigraphique établi pour l'étude des séquences sédimentaires permet de mieux contraindre la manière dont ces courants gravitaires sont enregistrés et préservés, à plusieurs échelles de temps.

Full textAbstract:
La marge Ligure est une marge passive soumise à une déformation tectonique compressive associée à la tectonique salifère messinienne. La reprise en compression de la marge s’accompagne d’une sismicité modérée récurrente ponctuée d’évènements plus forts. La marge Ligure est le siège d’une sédimentation importante au Plio-Quaternaire. Elle constitue un environnement propice à l’étude des déstabilisations gravitaires. L’objectif principal de ce travail était de décrire et caractériser les principaux mouvements en masse ayant affecté la marge continentale Ligure au cours du Plio-Quaternaire, de localiser les principales zones sujettes aux déstabilisations et d’identifier les facteurs pré-conditionnant et déclenchant les ruptures dans le but de mieux évaluer l’aléa gravitaire. Une large couverture de données bathymétriques, géophysiques et des carottages acquis sur l’ensemble de la marge a permis de réaliser une étude multi-échelles des processus de ruptures gravitaires et des facteurs déclenchant associés. Près de 1500 glissements ont été identifiés. L’étude de leur répartition spatio-temporelle illustre que l’ensemble de la marge a toujours été affectée par des déstabilisations de pente mais que les principales zones de ruptures auraient migré vers l’ouest au cours du Plio-Quaternaire. Les grandes ruptures sous-marines sont préférentiellement associées aux zones de déformation maximale, cette dernière étant contrôlée par la tectonique crustale et/ou la tectonique salifère. Il apparaît que les ruptures résultent plus généralement d’une association de facteurs distincts qui ont participé à fragiliser la stabilité des dépôts de la pente et qui ont pu provoquer leur ruptureThe Ligurian margin is a passive margin characterized by high sedimentation rates during the Plio-Quaternary. It is affected by a compressive tectonic deformation leading to the inversion of the margin, together with a salt tectonic. The present-day moderate seismic activity is punctuated by stronger seismic events. Thus, this margin offers a good natural laboratory to study submarine landslides and their triggering factors. Although the Var Turbidite System has been well investigated over the last 20 years, the morphology and tectonics/sedimentary processes affecting the whole margin remained poorly known. This study aims to describe and to characterize the main types of mass movements, their preferential locations along the Ligurian margin during the Plio-Quaternary and their triggering factors to improve geohazards assessment related to landslides. A dataset including bathymetric and geophysical data and cores allowed to realize a multi-scale study of submarine failures and their associated triggering factors. About 1500 landslides were identified on the margin and in the basin. The study of their spatio-temporal distribution revealed that the margin has always been affected by mass-wasting processes and that the main zones of landsliding migrated westward during the Plio-Quaternary. The largest submarine landslides are preferentially associated with the highest deformation rates and their location is controlled by crustal tectonics and/or salt tectonics. The initiation of failures results from the combination of several factors including the margin deformation, earthquakes, salt tectonics and sediment under-consolidation

Les marges continentales, passives ou actives, sont la principale voie de transfert sédimentaire entre le plateau continental et le bassin océanique profond et les plaines abyssales. Les pentes continentales sont le siège de processus d'érosion/dépôt sous le contrôle de transfert de flux particulaires continentaux chenalisés par des structures érosives, telles que les canyons sous‐marins, puis redistribues à l'ensemble de la marge. Les canyons érodent fortement les pentes continentales et contribuent à l'évolution de leur morphologie au cours du temps. On retrouve cependant des canyons sous‐marins qui ne sont pas en relation avec la présence d'un réseau fluviatile. De ce fait, la formation et l'évolution des canyons sous‐marins sont encore peu comprises. Ce travail de thèse s'intéresse aux processus de formation et d'évolution de six canyons sous-marins sur la Marge Ouest du Bassin Ligure et à dix systèmes de canyons sur la Marge Calabro-Ionienne. Le but de cette étude est de contraindre les principales caractéristiques morphométriques (longueur, largeur, profondeur, inclinaison, sinuosité), morphologique (éléments architecturaux, configuration) des canyons, de caractériser leur évolution amont‐aval et d'analyser leur structure interne, afin de mieux comprendre l'origine des canyons sous‐marins, leurs mécanismes de construction et leur évolution au cours du temps en relation avec le contexte géologique régional et leurs potentiels bassins versants subaérien. Pour cela, une approche basée sur une analyse morpho-bathymétrique et géophysiques a été mise en œuvre à partir de relevés bathymétriques complets des marges, de profils de sismiques, de Chirp et de SAR.

L'étude des bijoux - notion complexe pour la période prise en examen - et de leurs représentations, s'appuie sur l'analyse des images en deux dimensions de la Vallée d'Aoste, du Piémont, de Ligurie et de Lombardie aux XIVe et XVe siècle. Elle vise à observer les contextes et les types de support permettant d'observer des détails comme les objets précieux, ainsi qu'à déterminer les grands groupes de commanditaires des images mettant en scène ces objets. Elle vise ensuite à analyser la fréquence d'apparition des différents bijoux et accessoires de parure, ainsi qu'à déterminer les catégories de personnages les plus ornées, tout en confrontant ces résultats avec les autres sources à notre disposition: mobilier archéologique, objets d'orfèvrerie, documentation comptable, inventaires après décès, lois somptuaires, récits de chroniqueurs, sermons, correspondance, poésie, ainsi que les Lapidaires dédiés aux gemmes. Sont abordées les particularités mises en avant par les images, qui insistent sur les différentes valeurs morales attachées à chaque type d'objet de parure, à l'endroit du corps auquel il était destiné ainsi qu'au rang de celui qui les portait.Le recours à plusieurs études relevant du domaine de l'anthropologie historique permet d'observer le rôle important des occasions qui requéraient le port de ces objets ou qui en commandaient les échanges, découlant des nécessités imposées par un cérémonial très ritualisé, lors duquel les objets de parure jouaient un rôle de représentation et de protection.L'analyse s'oriente sur la « stratégie » déployée par les images et leurs commanditaires, au sein d'une logique des apparences visant à légitimer leur positionThe study about jewels and adornment accessories - a complex notion for the period in examination - and their representations, leans on the analysis of the two-dimensions images produced in Aosta Valley, Piedmont, Liguria and Lombardy in the 14th and 15th century.It aims at observing contexts and types of medium allowing images to show such details as jewels and adornment accessories, when still visible, and to determine the different groups of people who subscribed the images where these objects appear.It aims at analyzing the frequency of appearance of the various jewels and dress adornments, as well as determining which are the most decorated categories of characters, while confronting these results with the other sources at our disposal: archeological and goldsmiths' work finds, account books, inventories, sumptuary laws, chroniclers narratives, sermons, correspondence, poetry, and a particular genre of literature dedicated to gemstones: Lapidaries.The particularities advanced by images insist on the various moral values attached to every type of jewel and adornment object, their location on the body, as well as the rank of their owner.The recourse to several studies belonging to the historic anthropology domain allows focusing on the important role played by the occasions which required the bearing of these objects or which commanded their exchanges, ensuing from a ritualized ceremonial, during which the finery objects played a role of representation as well as protection.Finally, the analysis turns on the "strategy" displayed by images and, especially by those who ordered them, joining within logic of appearances, in order to legitimize their position
Lo studio dei gioielli – nozione complessa per il periodo preso in esame – e delle loro rappresentazioni, si basa sull’analisi delle immagini a due dimensioni prodotte nella Valle d’Aosta, in Piemonte, Liguria e Lombardia ne Trecento e Quattrocento. Mira innanzitutto ad osservare quali sono i contesti ed i tipi di produzione che permettono di osservare dettagli come gli accessori ornamentali, quando questi sono ancora reperibili, così come a determinare i grandi gruppi di promotori delle immagini raffiguranti questi oggetti. Mira poi ad analizzare in modo quantitativo la frequenza delle apparizione di quei differenti tipi di gioielli ed accessori preziosi, nonchè a determinare quali sono le categorie di personaggi più ornati, pure confrontando questi risultati con le altre fonti a disposizione. Tra queste si annoverano reperti archeologici e oggetti di oreficeria, ma anche fonti scritte : documentazione archivistica contabile, inventari, leggi suntuarie, opere di cronisti, sermoni, corrispondenza, poesia, così come une tipo particolare dedicato alle gemme : i Lapidari. Sono così evidenziate le particolarità messe in luce dalle immagini, che insistono sulle differenti caratteristiche morali legate ad ogni tipo di oggetti presi in conto, alla parte del corpo alla quale era destinato, così come al rango sociale di chi lo portava. Il ricorso a parecchi studi che rientrano nel campo dell’antropologia storica permette di osservare il ruolo importante delle occasioni che richiedevano di ornarsi con questi oggetti o che ne determinavano gli scambi, il che dérivava dalle necessità imposte da un cerimoniale molto ritualizzato, nel quale quegli oggetti preziosi assumevano nello stesso tempo una funzione di rappresentazione et di protezione. Infine, l’analisi si orienta sulla « strategia » sviluppata dalle immagini, e sopratutto dai loro donatori, iscrivendosi in una logica delle apparenze che tendeva a legittimare la loro posizione

Longacre, Judith. "Camillo Sbarbaro and the Ligurian poetic tradition." Thesis, 2003. http://spectrum.library.concordia.ca/2341/1/MQ83963.pdf.
Full textAbstract:
This thesis presents a human and artistic profile of Camillo Sbarbaro (1888-1967). It is set against the geographical and historical background of the first part of the twentieth century to which Sbarbaro belonged. It explains the salient points of the poetic tradition of Liguria emphasizing that Liguria, both as a physical reality and as an objective correlative of existential meditation, played a significant role, not only in the works of the poets born in this region but also in the works which visitors or admirers have written to describe Liguria. In order to underline the specificity of the Ligurian sensibility vis-à-vis the landscape, the thesis dedicates a chapter to the journal La Riviera Ligure (1895-1919). Camillo Sbarbaro was one of its major contributors, and by writing for this magazine, he began his literary career. The final chapter of the first part of the thesis is a glance at the historical, political and the artistic themes at the end of the nineteenth century. The second part of this thesis presents the arrival of modern poetry in Italy and links it to the rise of existentialism in early twentieth century Europe. Another section deals with the often unspoken debt of Eugenio Montale to Sbarbaro--a debt of themes, language, ideas--all never properly nor fully acknowledged. A third section compares and contrasts Montale and Sbarbaro and ascertains their artistic merit. In the comparison Sbarbaro emerges as being as significant as Montale. Sbarbaro is presented with Giuseppe Ungaretti as the harbinger of contemporary Italian poetry and Montale becomes to an extent Sbarbaro's pupil

Full textAbstract:
The present doctoral thesis investigated fundamental aspects of temporal and spatial dynamics of hake (Merluccius merluccius) recruitment in the Tyrrhenian and Ligurian Sea (Mediterranean).
We identified recruit and post-recruit as two well distinct phases of hake juvenile life stage according to a marked bathymetric segregation. Hake juveniles enter the post-recruit stage at a length range between 13.2 cm and 15.8 cm through a sharp migration from the margin of the shelf-break and upper slope to the shallower continental shelf waters. Spatial models provided accurate identification of the main areas of aggregation of hake recruits before their migration and spreading on the shelf. We found that nurseries in the Tyrrhenian and Ligurian Sea are characterised by some of the highest densities of recruits observed in the Mediterranean, suggesting these areas could play an important role for the dynamics of hake population at a larger scale far beyond the study area. The analysis of time series data for two different periods of the year demonstrated an inter-annual and seasonal stability in the spatial location of the main nursery areas and a strong association for specific habitats of the shelf-break. Together with these main nurseries, a certain number of secondary nurseries were detected only in certain years, but their variability and importance for the population remain to be addressed.
Wide fluctuations in the abundance of hake recruits were found to be strongly influenced by both oceanographic and biological processes. Thermal anomalies in summer, characterised by high peaks in water temperature, revealed a negative effect on the abundance of recruits in autumn, possibly due to a reduction in hake egg and larval survival rates. Recruitment was also reduced when elevated sea-surface temperatures in summer were coupled with low levels of water circulation. Enhanced spring primary production related to late winter low temperatures are known to affect water mass productivity in the following months, and according to our results hake spring recruitment. We found a dome-shaped relationship between wind mixing in early spring and recruitment that was interpreted as an “optimal environmental window” in which intermediate water mixing level can play a positive role in phytoplankton displacement, larval feeding rate and appropriate larval drift.
The temporal and spatial persistence of hake nurseries represented fundamental features for testing the effects of a spatial management of the population particularly during the highly vulnerable recruit phase. The effect of different levels of protection on recruits were tested through model simulations and compared with a more general reduction of fishing effort, providing unexpected results on the mature portion of the population.

Full textAbstract:
This work provides a structural study on some successions of the Ligurian Accretionary Complex (LAC; southern Italy), Maghrebian Flysch Basin (MFB; Morocco) and External Dorsale Calcaire (Morocco). The LAC Units, cropping out in the southern Apennines include the sedimenary deep basin successions of Nord Calabrese, Parasicilide and Sicilide. Presently they are the highest tectonic units of the South Apennine fold and thrust belt. They are all characterized by a polyphasic and
progressive deformation related to the Early Miocene inclusion in the tectonic accretionary wedge, by means of a frontal accretion mechanism, with a mean E/SE tectonic vergence. A subsequent deformation stage, associated to the eastward migration of the thrust front, affecting also the Middle-Upper Miocene unconformable wedge-top basin deposits, was characterized by a mean E/NE tectonic transport. In this orogenic phase the Apennine thrust sheet pile, formed by LAC and Apennine Platform Units, tectonically covered the successions located in the westernmost sector of the Lagonegro-Molise Basin. Finally a Pliocene-Middle Pleistocene regional fold set deformed the whole orogenic prism, comprised the LAC Units as consequence of a thick-skinned tectonics expressed by means of deeply rooted thrusts in the buried Apulian Platform carbonates. The metamorphic units of LAC, analyzed in this study, are the Frido and Diamante-Terranova Units, cropping out at Calabria-Basilicata
boundary and northern Calabria, respectively. Both units are characterized by a HP/LT metamorphism reaching pressures of ca. 1.4/1.2 and 1.0 GPa and temperatures of 350 360 and 380 °C, respectively. The HP/LT parageneses include the Fe-carpholite, chlorite and phengite for the Frido and glaucophane, lawsonite, epidote and chlorite
for the Diamante-Terranova Unit. The tectonic exhumation was recorded by Ca amphiboles. The P-T-paths, presented below, of both units indicate a cool and rapid
exhumation. This is testified also by the preservation of HP/LT mineral parageneses and by non-isothermal exhumation such as marked in the P-T-paths of the Frido(this work) and Diamante-Terranova (Liberi and Piluso, 2009) Units. These units were subducted in the latest Oligocene and Early Eocene, respectively, with their complete exhumation in the middle Tortonian. The comparable geodynamic evolution of the LAC Units suggests an origin of all successions in a common oceanic domain
(Ligurian Ocean) characterized by a western sector floored by oceanic crust (Diamante-Terranova domain), a central sector represented by an Ocean Continent Transition (Frido and Nord-Calabrese domain) and an eastern area formed by thinned continental crust (Parasicilide and Sicilide domain). A further aim of this study is the reconstruction of the tectonic evolution of some successions of the Maghrebian Flysch Basin (MFB) domain (Predorsalian and Massylian Units) and the External Dorsale Calcaire in a key area (Chefchaouen) of
the Rif chain in the northern Morocco. Maghrebian Flysch Basin successions show a comparable stratigraphy with the sedimentary LAC successions, suggesting paleogeographic continuity between LAC, located to E/NE, and the MFB to the W. The Triassic-Lower Miocene External Dorsale Calcaire succession overthrust the Predorsalian Unit through a regional thrust fault well-exposed in Chefchaouen area. The kinematic analysis of this structure and all minor structures in the footwall,
indicate a SW-tectonic vergence. The Predorsalian unit in turn overthrust the Massylian succession characterized by a similar progressive deformation. The whole tectonic pile was subsequentely deformed by thrust and folds verging to NW. Like the sedimentary LAC units, the MFB Units were deformed by frontal accretion in the
Burdigalian-Langhian time. The External Dorsale Calcaire provides a good example of Inversion Tectonics. The Liassic succession (cherty limestones and conglomerates)
recorded the extension related to the Jurassic rifting of the Neotethys Domain as normal faulting and veining.The subsequent inclusion of these rocks in the orogenic
wedge, which mainly occurred in the Miocene time, deformed the most of pre-orogenic structures in a passive manner, with only few cases of reverse reactivation;
whereas, frequently, pre-orogenic normal fault planes show only an indentation of hanging-wall and footwall (buttressing effect). The orogenic deformation includes two main stages; the first tectonic pulse, which occurred during the Burdigalian-Langhian interval, was characterized by a NE-SW shortening and recorded by folds, thrust and back-thrust faults. During this stage the carbonates of the External Dorsale Calcaire
tectonically covered the Predorsalian succession, producing, in the thrust front, a SW verging regional fold. The second orogenic deformation, consisting of a NW-SE shortening, was expressed by thrust faults and related folds both verging to NW and SE, which probably occurred in the Late Miocene-Pliocene time.
