Valorizzazione di cartografia storica attraverso moderne tecniche geomatiche: recupero metrico, elaborazione e consultazione in ambiente digitale

“Cartographic heritage” is different from “cartographic history”. The second term refers to the study of the development of surveying and drawing techniques related to maps, through time, i.e. through different types of cultural environment which were background for the creation of maps. The first term concerns the whole amount of ancient maps, together with these different types of cultural environment, which the history has brought us and which we perceive as cultural values to be preserved and made available to many users (public, institutions, experts). Unfortunately, ancient maps often suffer preservation problems of their analog support, mostly due to aging. Today, metric recovery in digital form and digital processing of historical cartography allow preserving map heritage. Moreover, modern geomatic techniques give us new chances of using historical information, which would be unachievable on analog supports. In this PhD thesis, the whole digital processing of recovery and elaboration of ancient cartography is reported, with a special emphasis on the use of digital tools in preservation and elaboration of cartographic heritage. It is possible to divide the workflow into three main steps, that reflect the chapter structure of the thesis itself: • map acquisition: conversion of the ancient map support from analog to digital, by means of high resolution scanning or 3D surveying (digital photogrammetry or laser scanning techniques); this process must be performed carefully, with special instruments, in order to reduce deformation as much as possible; • map georeferencing: reproducing in the digital image the native metric content of the map, or even improving it by selecting a large number of still existing ground control points; this way it is possible to understand the projection features of the historical map, as well as to evaluate and represent the degree of deformation induced by the old type of cartographic transformation (that can be unknown to us), by surveying errors or by support deformation, usually all errors of too high value with respect to our standards; • data elaboration and management in a digital environment, by means of modern software tools: vectorization, giving the map a new and more attractive graphic view (for instance, by creating a 3D model), superimposing it on current base maps, comparing it to other maps, and finally inserting it in GIS or WebGIS environment as a specific layer. The study is supported by some case histories, each of them interesting from the point of view of one digital cartographic elaboration step at least. The ancient maps taken into account are the following ones: • three maps of the Po river delta, made at the end of the XVI century by a famous land-surveyor, Ottavio Fabri (he is single author in the first map, co-author with Gerolamo Pontara in the second map, co-author with Bonajuto Lorini and others in the third map), who wrote a methodological textbook where he explains a new topographical instrument, the squadra mobile (mobile square) invented and used by himself; today all maps are preserved in the State Archive of Venice; • the Ichnoscenografia of Bologna by Filippo de’ Gnudi, made in the 1702 and today preserved in the Archiginnasio Library of Bologna; it is a scenographic view of the city, captured in a bird’s eye flight, but also with an icnographic value, as the author himself declares; • the map of Bologna by the periti Gregorio Monari and Antonio Laghi, the first map of the city derived from a systematic survey, even though it was made only ten years later (1711–1712) than the map by de’ Gnudi; in this map the scenographic view was abandoned, in favor of a more correct representation by means of orthogonal projection; today the map is preserved in the State Archive of Bologna; • the Gregorian Cadastre of Bologna, made in 1831 and updated until 1927, now preserved in the State Archive of Bologna; it is composed by 140 maps and 12 brogliardi (register volumes). In particular, the three maps of the Po river delta and the Cadastre were studied with respect to their acquisition procedure. Moreover, the first maps were analyzed from the georeferencing point of view, and the Cadastre was analyzed with respect to a possible GIS insertion. Finally, the Ichnoscenografia was used to illustrate a possible application of digital elaboration, such as 3D modeling. Last but not least, we must not forget that the study of an ancient map should start, whenever possible, from the consultation of the precious original analogical document; analysis by means of current digital techniques allow us new research opportunities in a rich and modern multidisciplinary context.

Formazione e Competenze Professionali: una ricerca empirica sui Cassaintegrati in deroga della regione Emilia Romagna

The general theme of the present inquiry concerns the role of training and continuous updating of knowledge and skills in relation to the concept of employability and social vulnerability. The empirical research has affected the entire calendar year 2010, namely from 13 February 2010 to December 31, 2010: data refer to a very specific context or to the course funded by the Emilia Romagna region and targeted to employees in cassintegrazione notwithstanding domiciled in the region. The investigations were performed in a vocational training scheme accredited by the Emilia Romagna for the provision of publicly funded training courses. The quantitative data collected are limited to the region and distributed in all the provinces of Emilia Romagna; It addressed the issue of the role of continuing education throughout life and the importance of updating knowledge and skills, such as privileged instruments to address the instability of the labor market and what strategy to reduce the risk unemployment. Based on the different strategies that the employee puts in place during their professional careers, we introduce two concepts that are more common in the so-called knowledge society, namely the concept of social vulnerability and employability. In modern organizations becomes relevant knowledge they bring workers and the relationships that develop between people and allowing exponentially and disseminate such knowledge and skills. The knowledge thus becomes the first productive force, defined by Davenport and Prusak (1998) as "fluid combination of experience, values, contextual information and specialist knowledge that provides a framework for the evaluation and assimilation of new experience and new information ". Learning at work is a by stable explicit and conscious, and even enjoyable for everyone, especially outside of a training intervention. It then goes on to address the specific issue of training, under the current labor market increasingly deconstructed.

Il trattato ‘Practica musice’ di Franchino Gaffurio (1496). Genesi, tradizione del testo, trascrizione interpretativa e traduzione.

La ricerca consiste nell’edizione e traduzione del trattato ‘Practica musice’ di Franchino Gaffurio corredata da apparati critici e storico-contestuali. Si inizia con la biografia dell’autore redatta secondo gli ultimi dati disponibili e si presenta una esposizione del contenuto del trattato con proposte di chiarimenti dei passi più oscuri. Segue quindi uno studio dei cambiamenti intercorsi tra le parti del trattato come trasmesse nei manoscritti preparatori e la sua versione finale a stampa, seguito da una indagine sulle edizioni successive all’editio princeps, con tabelle sulle varianti tra le edizioni. Vengono quindi offerte la trascrizione interpretativa del testo latino del trattato (che può essere considerata la più corretta attualmente disponibile ed è l’unica a riportare numeri di partizione testuale) seguita dalla sua traduzione in italiano, con trascrizione degli esempi musicali. Il trattato, diviso in quattro libri, ha per argomenti rispettivamente il cantus planus e le scale modali gregoriane, la musica misurata e le figure della notazione, l’arte del contrappunto e la più ampia casistica disponibile sulle proporzioni ritmiche.
