"Il carceriere di sé medesimo" di Lodovico Adimari e Alessandro Melani, Firenze 1681. Dalla «comedia» di Pedro Calderón de la Barca al «drama per musica» italiano di fine Seicento

Questo lavoro è imperniato sullo studio di uno dei melodrammi più interessanti della fine del XVII secolo: “Il carceriere di sé medesimo” di Lodovico Adimari (1644-1708) e Alessandro Melani (1639-1703), allestito per la prima volta a Firenze nel 1681, e ripreso nel giro di una ventina d’anni a Reggio (1684), a Bologna (1697) e a Vienna (1702). L’opera vanta un’origine drammatica di spicco: risale infatti alla commedia “Guardarse a sí mismo” di Pedro Calderón de la Barca (1600-1681) mediata dal “Geôlier de soi-mesme” di Thomas Corneille (1625-1709), e presenta qualità poetiche e musicali evidenti, assicurate dai nomi del poeta Lodovico Adimari e del compositore Alessandro Melani. A ciò si aggiungano una tradizione articolata in quattro allestimenti, nonché un elevato numero di testimoni superstiti: cinque edizioni del libretto (testimoniate da numerosi esemplari) e il numero fortunatissimo di tre partiture manoscritte, conservate a Parigi, Bologna e Modena. La tesi contiene l’edizione critica del “Carceriere di sé medesimo” di Adimari con tutte le varianti accumulatesi nella riedizione del libretto e nella copiatura della partitura, l’analisi del dramma, a partire dal confronto tra i testi di Calderón, Corneille e Adimari, e lo studio delle sue componenti drammatiche, formali e contenutistiche. Si aggiunge uno studio sul contesto storico-musicale degli allestimenti di Firenze, Reggio, Bologna e Vienna, nonché l’edizione dei restanti tre drammi di Adimari: la commedia “Le gare dell’amore e dell’amicizia” (1679), e il dramma per musica “L’amante di sua figlia” (1684).

Conformation and Stereodynamic of Hindered Aromatic System

The preparation of conformationally hindered molecules and their study by DNMR and computational methods are my thesis’s core. In the first chapter, the conformations and the stereodynamics of symmetrically ortho-disubstituted aryl carbinols and aryl ethers are described. In the second chapter, the structures of axially chiral atropisomers of hindered biphenyl carbinols are studied. In the third chapter, the steric barriers and the -barrier of 1,8-di-aylbiphenylenes are determined. Interesting atropisomers are found in the cases of arylanthrones, arylanthraquinones and arylanthracenes and are reported in the fourth chapter. By the combined use of dynamic NMR, ECD spectroscopy and DFT computations, the conformations and the absolute configurations of 2-Naphthylalkylsulfoxides are studied in the fifth chapter. In the last chapter, a new synthetic route to ,’-arylated secondary or tertiary alcohols by lithiated O-benzyl-carbamates carrying an N-aryl substituent and DFT calculations to determinate the cyclic intermediate are reported. This work was done in the research group of Prof. Jonathan Clayden, at the University of Manchester.

Knowledge Flows and Networks: the Interplay between Local and Global Linkages within Bangalore IT Cluster

This doctoral work gains deeper insight into the dynamics of knowledge flows within and across clusters, unfolding their features, directions and strategic implications. Alliances, networks and personnel mobility are acknowledged as the three main channels of inter-firm knowledge flows, thus offering three heterogeneous measures to analyze the phenomenon. The interplay between the three channels and the richness of available research methods, has allowed for the elaboration of three different papers and perspectives. The common empirical setting is the IT cluster in Bangalore, for its distinguished features as a high-tech cluster and for its steady yearly two-digit growth around the service-based business model. The first paper deploys both a firm-level and a tie-level analysis, exploring the cases of 4 domestic companies and of 2 MNCs active the cluster, according to a cluster-based perspective. The distinction between business-domain knowledge and technical knowledge emerges from the qualitative evidence, further confirmed by quantitative analyses at tie-level. At firm-level, the specialization degree seems to be influencing the kind of knowledge shared, while at tie-level both the frequency of interaction and the governance mode prove to determine differences in the distribution of knowledge flows. The second paper zooms out and considers the inter-firm networks; particularly focusing on the role of cluster boundary, internal and external networks are analyzed, in their size, long-term orientation and exploration degree. The research method is purely qualitative and allows for the observation of the evolving strategic role of internal network: from exploitation-based to exploration-based. Moreover, a causal pattern is emphasized, linking the evolution and features of the external network to the evolution and features of internal network. The final paper addresses the softer and more micro-level side of knowledge flows: personnel mobility. A social capital perspective is here developed, which considers both employees’ acquisition and employees’ loss as building inter-firm ties, thus enhancing company’s overall social capital. Negative binomial regression analyses at dyad-level test the significant impact of cluster affiliation (cluster firms vs non-cluster firms), industry affiliation (IT firms vs non-IT fims) and foreign affiliation (MNCs vs domestic firms) in shaping the uneven distribution of personnel mobility, and thus of knowledge flows, among companies.

Atmospheric radiative transfer in multiple scattering conditions. Application to NWP models.

High spectral resolution radiative transfer (RT) codes are essential tools in the study of the radiative energy transfer in the Earth atmosphere and a support for the development of parameterizations for fast RT codes used in climate and weather prediction models. Cirrus clouds cover permanently 30% of the Earth's surface, representing an important contribution to the Earth-atmosphere radiation balance. The work has been focussed on the development of the RT model LBLMS. The model, widely tested in the infra-red spectral range, has been extended to the short wave spectrum and it has been used in comparison with airborne and satellite measurements to study the optical properties of cirrus clouds. A new database of single scattering properties has been developed for mid latitude cirrus clouds. Ice clouds are treated as a mixture of ice crystals with various habits. The optical properties of the mixture are tested in comparison to radiometric measurements in selected case studies. Finally, a parameterization of the mixture for application to weather prediction and global circulation models has been developed. The bulk optical properties of ice crystals are parameterized as functions of the effective dimension of measured particle size distributions that are representative of mid latitude cirrus clouds. Tests with the Limited Area Weather Prediction model COSMO have shown the impact of the new parameterization with respect to cirrus cloud optical properties based on ice spheres.

Tectonic geomorphology and active strain of the Northern Apennines mountain front

The Northern Apennines (NA) chain is the expression of the active plate margin between Europe and Adria. Given the low convergence rates and the moderate seismic activity, ambiguities still occur in defining a seismotectonic framework and many different scenarios have been proposed for the mountain front evolution. Differently from older models that indicate the mountain front as an active thrust at the surface, a recently proposed scenario describes the latter as the frontal limb of a long-wavelength fold (> 150 km) formed by a thrust fault tipped around 17 km at depth, and considered as the active subduction boundary. East of Bologna, this frontal limb is remarkably very straight and its surface is riddled with small, but pervasive high- angle normal faults. However, west of Bologna, some recesses are visible along strike of the mountain front: these perturbations seem due to the presence of shorter wavelength (15 to 25 km along strike) structures showing both NE and NW-vergence. The Pleistocene activity of these structures was already suggested, but not quantitative reconstructions are available in literature. This research investigates the tectonic geomorphology of the NA mountain front with the specific aim to quantify active deformations and infer possible deep causes of both short- and long-wavelength structures. This study documents the presence of a network of active extensional faults, in the foothills south and east of Bologna. For these structures, the strain rate has been measured to find a constant throw-to-length relationship and the slip rates have been compared with measured rates of erosion. Fluvial geomorphology and quantitative analysis of the topography document in detail the active tectonics of two growing domal structures (Castelvetro - Vignola foothills and the Ghiardo plateau) embedded in the mountain front west of Bologna. Here, tilting and river incision rates (interpreted as that long-term uplift rates) have been measured respectively at the mountain front and in the Enza and Panaro valleys, using a well defined stratigraphy of Pleistocene to Holocene river terraces and alluvial fan deposits as growth strata, and seismic reflection profiles relationships. The geometry and uplift rates of the anticlines constrain a simple trishear fault propagation folding model that inverts for blind thrust ramp depth, dip, and slip. Topographic swath profiles and the steepness index of river longitudinal profiles that traverse the anti- clines are consistent with stratigraphy, structures, aquifer geometry, and seismic reflection profiles. Available focal mechanisms of earthquakes with magnitude between Mw 4.1 to 5.4, obtained from a dataset of the instrumental seismicity for the last 30 years, evidence a clear vertical separation at around 15 km between shallow extensional and deeper compressional hypocenters along the mountain front and adjacent foothills. In summary, the studied anticlines appear to grow at rates slower than the growing rate of the longer- wavelength structure that defines the mountain front of the NA. The domal structures show evidences of NW-verging deformation and reactivations of older (late Neogene) thrusts. The reconstructed river incision rates together with rates coming from several other rivers along a 250 km wide stretch of the NA mountain front and recently available in the literature, all indicate a general increase from Middle to Late Pleistocene. This suggests focusing of deformation along a deep structure, as confirmed by the deep compressional seismicity. The maximum rate is however not constant along the mountain front, but varies from 0.2 mm/yr in the west to more than 2.2 mm/yr in the eastern sector, suggesting a similar (eastward-increasing) trend of the apenninic subduction.

Keplero e la musica. Il Libro III dell'Harmonice mundi (Linz, 1619): traduzione e Introduzione

Questo lavoro si concentra su un particolare aspetto della sfaccettata ricerca scientifica di Johannes Kepler (1571-1630), ossia quello teorico-musicale. I pensieri dell’astronomo tedesco riguardanti tale campo sono concentrati – oltre che in alcuni capitoli del Mysterium cosmographicum (1596) ed in alcune sue lettere – nel Libro III dell’Harmonices mundi libri quinque (1619), che, per la sua posizione mediana all’interno dell’opera, tra i primi due libri geometrici e gli ultimi due astronomici, e per la sua funzione di raccordo tra la «speculazione astratta» della geometria e la concretizzazione degli archetipi geometrici nel mondo fisico, assume la struttura di un vero e proprio trattato musicale sul modello di quelli rinascimentali, nel quale la «musica speculativa», dedicata alla teoria delle consonanze e alla loro deduzione geometrica precede la «musica activa», dedicata alla pratica del canto dell’uomo nelle sue differenze, generi e modi. La tesi contiene la traduzione italiana, con testo latino a fronte, del Libro III dell’Harmonice, e un’ampia introduzione che percorre le tappe fondamentali del percorso biografico e scientifico che hanno portato alla concezione di quest’opera – soffermandosi in particolare sulla formazione musicale ricevuta da Keplero, sulle pagine di argomento musicale del Mysterium e delle lettere, e sulle riflessioni filosofico-armoniche sviluppate negli anni di ricerca – e offre gli elementi fondamentali per poter comprendere l’Harmonice mundi in generale e il Libro III in particolare. A ciò si aggiunge, in Appendice, la traduzione, anch’essa con testo latino a fronte, della Sectio V, dedicata alla musica, del Liber IX dell’Almagestum novum (1651) di Giovanni Battista Riccioli (1598-1671), interessante sia dal punto di vista della recezione delle teorie di Keplero che dal punto di vista della storia delle idee musicali.
