Socio-economic impacts under different sea-level rise scenarios: analysis at local level along the coastal area of Rome (Italy)
No full textSea-level rise (SLR) is often associated with climate change and human action in modifying nature and the environment. The research presented in this paper concerns the consequential effects of this hypothesis and impacts of SLR in Italy, along the Rome coastal area, in the Ostia district. The study was carried out at the local level, using micro-spatial data, in the context of the European Union’s Seventh Framework Programme (FP7) project SECOA – Solutions for Environmental Contrasts in Coastal Areas; its aim is to offer local policy makers a tool to support and
facilitate their decision-making processes. Effects and impacts are analysed and presented for two alternative SLR scenarios. The first one follows the hypotheses made by the Intergovernmental Panel on Climate Change (IPCC ), the second one those made by Rahmstorf, in 2007. The two scenarios consider a SLR of 0.2-0.6 m and 1.00-1.40 m, respectively, by the year 2100. The coastal surface area flooded in the IPCC scenario equates to ca. 876 m2, while the flooding in the Rahmstorf scenario totalled ca. 690,322 m2. Damages in terms of loss of land with different uses, loss of dwellings, loss of jobs, need for a relocation of resident population are the most severe estimated impacts of that extreme
event of the Rahmstorf scenario

ABSTRACT DI CONFERENZA INTERNAZIONALE. Colonia (Germania): Environmental Contrasts in Coastal Areas: the Artificial Neural Networks as a Strategic Method of Analysis.
No full textThe FP7 European project Secoa (Solutions for Environmental Contrasts in Coastal Areas) produced an elevated volume of data formalized in different complex matrices. Using statistical methods is now possible to explore the articulated picture of each data set complex world and hypothesize some tendencies useful to compare macroscopically the analogies and the differences between each area. The Artificial Neural Network methods give now the opportunity of creating a bottom-up model of this complexity that can be explored as a virtual hyper-surface of linear an/or non-linear, symmetrical and/or asymmetrical, regular and/or fuzzy relations between variables. The results of these explorations on the virtual hyper-surface can also be organized and displayed in the geographical space using GIS technology and Graph Theory, in other words the results of these explorations will produce a synthetic interpretation of some tendencies related to selected aspects of the so called SECOA human mobility

Youth mobility and the development of human capital: is there a Southern European model?
Full text linkRecent Southern European migration is characterised by important flows of higher-skilled young persons. The balance between the risk of a new brain drain and brain waste and the opportunity of brain gain depends on how the young migrants integrate into the labour market of destination, the new abilities they acquire and the possibilities of re-integrating into the labour market of origin, in case of return migration. In this paper we discuss the contribution of international youth mobility to the development of human capital. We focus on the individual gain in origin countries/regions generated by circulation and return and concentrate on total human capital. Our results – based on 120 indepth interviews conducted in Italy and Spain, in both core (Rome and Madrid) and peripheral (Apennines and Andalusia) areas, with young students and lower- and higher-skilled workers – show that both Italians and Spaniards have acquired soft skills and these informal and tacit competences are considered to be as important as formal and explicit ones. For young Italians, brain circulation predominates and the human capital gained during migration results in better employability and earnings; for young Spaniards, circulation and return are more difficult in spite of their enriched human capital
Imago Tusciae: A digital archive of historical maps of Tuscany (Italy)
No full textIl progetto Imago Tusciae, realizzato presso il Laboratorio di Geografia del Dipartimento di Storia dell'Università di Siena (gruppo di lavoro: Cinzia Bartoli, Luca Deravignone, Barbara Gelli, Claudio Greppi, Giuseppe Lauricella, Fortunato Lepore, Giancarlo Macchi Janica, Giulio Tarchi), è un archivio digitale on line della cartografia storica della Toscana. Al momento, l’archivio comprende circa 2000 documenti appartenenti a diversi fondi dell’Archivio di Stato di Siena, ai quali si aggiungeranno presto le mappe dell'Archivio di Stato di Grosseto. L'obiettivo è quello di accogliere progressivamente nell’archivio la documentazione cartografica delle diverse conservatorie della Toscana (archivi e biblioteche pubblici e privati), oltre a quella relativa alla Toscana ma conservata altrove (in Italia e all’estero). Oltre che presentarsi come mezzo di consultazione dei dati e di ricerca di informazioni, l’applicazione permette la visualizzazione delle riproduzioni delle mappe e di altri documenti correlati ad alta risoluzione ed offre strumenti di studio e di riflessione: schede informative sui documenti, elenchi di autori con relative notizie biografiche, riferimenti bibliografici, elenchi di fondi archivistici e atlanti di mappe con loro descrizione e una cronologia interattiva e localizzata sulla mappa della Toscana odierna.
Sfruttando le tecniche caratteristiche di Web 2.0 (grazie alla navigazione tabbed) e utilizzando un’architettura di interfaccia lineare e intuitiva, l’applicazione cerca di offrire all’utente una user experience il più possibile simile a quella che si vive sul tavolo di uno studioso in archivio con documenti di provenienza diversa e spunti suscitati dal vaglio incrociato delle fonti.The Imago Tusciae project, developed at the Geography Workshop of the Department of History at the University of Siena (working group: Cinzia Bartoli, Luca Deravignone, Barbara Gelli, Claudio Greppi, Giuseppe Lauricella, Fortunato Lepore, Giancarlo Macchi Janica and Giulio Tarchi), is an online digital archive of the historic cartography of Tuscany. At present the archive comprises around 2,000 documents belonging to different fonds of the Siena State Archives, soon to be joined by the maps from the Grosseto State Archives. The objective is that of progressively gathering within the archive the cartographic documentation from the various registries in Tuscany (archives and both public and private libraries) as well as that concerning Tuscany but conserved elsewhere (in Italy and abroad).
In addition to operating as a means for consulting the data and seeking information, the application also makes it possible to view the maps and other related documents in high resolution and offers a range of tools for study and reflection: informative factsheets on the documents, lists of authors with respective biographical details, bibliographic references, lists of archive fonds and atlases of maps complete with descriptions and an interactive chronology localised on the map of modern-day Tuscany. By exploiting the technical features of Web 2.0 (through tabbed browsing) and using a linear and intuitive interface architecture, the application seeks to offer a user experience as similar as possible to that of a scholar at a desk in an archive, with documents of diverse provenance and suggestions generated by the cross-referenced examination of the sources
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Geographical analyses and artificial intelligence for the study of late medieval settlements in Southern Tuscany (Italy)
No full textThis paper presents how Artificial Neural Networks (ANN), integrated in a GIS platform, has been used to analyse ancient settlement patterns, in particular fortified villages and medieval settlements in central Italy. The idea at the base of this method is that each settlement system can be seen as an outcome of a social and territorial background. Through the use of different data such as satellite images, historical cartography and archaeological evidences, it is possible to individuate, with the help of ANN methodologies, some of the links between human settlements and the territory. This methodology allows a double approach: firstly the analysis of ancient settlement pattern distribution itself, and secondly the identification of undiscovered archaeological sites. Particular focus will be put on evaluation and quantification of the relationship between late medieval castles (Xth-XIIIth Century A.D.) and environmental variables, and between actual and ancient land use, with the integration of satellite imagery, in particular Landsat, and the use of historical cartography.Cet article montre comment les réseaux de neurones artificiels (ANN), intégrés dans une plateforme GIS, ont été utilisés pour analyser les modèles d’anciens habitats, en particulier des villages fortifiés et des habitats médiévaux en Italie centrale. L’idée de base de cette méthode est que chaque habitat peut être interprété comme une expression du contexte social et territorial. Utilisant des données différentes comme les images satellitaires, la cartographie historique et les évidences archéologiques, il est possible de localiser, grâce à l’utilisation des ANN, quelques-uns des liens présents entre l’habitat humain et le territoire. Cette méthode permet une double approche: l’analyse des habitats mêmes et l’identification de sites inconnus. Une attention particulière a été portée à l’analyse et à la quantification des relations entre les châteaux (Xème-XIIIème siècles) et aux variables territoriales, mais aussi à l’utilisation du sol, à l’intégration d’images satellitaires, en particulier Landsat, et à l’utilisation de la cartographie historique
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
