Mass-transport deposits on Mediterranean continental margins

Extensive mass transport deposits and multiple slide scars testify widespread and recurrent submarine sediment failures occurring during the late Quaternary on the SW-Adriatic and SE-Sicilian margins. These mass movements and their consequences contributed to shape the continental slopes and fill the basins with characteristic signatures. Geomorphological, seismo-stratigraphic, sedimentological and biostratigraphic data provide clues to: 1) define distinct failure mechanisms investigating on factors that determine dissimilar organization of coeval displaced masses, 2) reconstruct successive phases of failure stressing on the same location where slide scars crosscut and mass-transport deposits overlap, 3) analyze regional setting and indicate the most suitable place where to calculate mass wasting frequency. Discussions on the role of fluid flow, currents activity and tectonic deformation determine a wider view on the construction of the studied continental margins.

Dalla Francia all'Italia: impegno politico, inchiesta e transfers culturali alle origini della sociologia del lavoro in Italia

Sociology of work in Italy revived at the end of WWII, after thirty years of forced oblivion. This thesis examines the history of discipline by considering three paths that it followed from its revival up to its institutionalization: the influence of the productivity drive, the role of trade unions and the activity of early young researchers. European Productivity Agency's Italian office Comitato Nazionale per la Produttività propagandised studies on management and on the effects of the industrialization on work and society. Academicians, technicians, psychologists who worked for CNP started rethinking sociology of work, but the managerial use of sociology was unacceptable for both trade unions and young researchers. So “free union” CISL created a School in Florence with an eager attention to social sciences as a medium to become a new model union, while Marxist CGIL, despite its ideological aversion to sociology, finally accepted the social sciences lexicon in order to explain the work changes and to resist against the employers' association offensive. On the other hand, political and social engagement led a first generation of sociologists to study social phenomenon in the recently industrialized Italy by using the sociological analysis. Finally, the thesis investigate the cultural transfers from France, whose industrial sociology (sociologie du travail) was considered as a reference in continental Europe. Nearby the wide importance of French sociologie, financially aided by planning institutions in order to employ it in the industrial reconstruction, other minor experiences such as the social surveys accomplished by worker-priests in the suburbs of industrial cities and the heterodox Marxism of the review “Socialisme ou Barbarie” influenced Italian sociology of work.

Late Quaternary geological evolution of the Montenegro and Northern Albania continental margins

The object of this work has been the analysis of natural processes controlling the geological evolution of the Montenegro and Northern Albania Continental Margin (MACM) during the Late Quaternary. These include the modern sediment dispersal system and oceanographic regime, the building and shaping of the shelf margin at the scale of 100 kyr and relative to the most recent transition between glacial and interglacial periods. The analysis of the new data shows that the MACM is a shelf-slope system formed by a suite of physiographic elements, including: an inner and an outer continental shelf, separated by two tectonically-controlled morphological highs; a lobated drowned mid-shelf paleodelta, formed during the last sea level fall and low stand; an upper continental slope, affected by gravity-driven instability and a system of extensional faults with surficial displacement, featuring an orientation coherent with the regional tectonics. The stratigraphic study of the MACM shows a clear correspondence between the Late Pleistocene/Holocene mud-wedge and the low reflectivity sectors of the inner shelf. Conversely, most of the outer shelf and part of the continental slope expose deposits from the last sea level low stand, featuring a general sediment starving condition or the presence of a thin postglacial sediments cover. The MACM shows uplift in correspondence of the Kotor and Bar ridges, and subsidence in the outer shelf and upper slope sectors. In fact, seaward of these tectonic ridges, the sparker seismic profile show the presence of four well-defined seismo-stratigraphic sequences, interpreted as forced regression deposits, formed during the last four main glacial phases. In this way, the MACM records the 100 kyr scale sea level fluctuations on its seismo-stratigraphic architecture over the last 350 kyr. Over such time range, through the identification of the paleoshoreline deposits, we estimated an average subsidence rate of about 1.2 mm/yr.
