No full textIn large cities creative industries tend to geographically concentrate. The purpose of this paper is to empirically test the hypothesis that this geographic concentration derives from the benefits on the innovative urban milieu.
A spatial regression model is estimated using as dependent variable the number of creative firms per census block in the Metropolitan city of Rome. Empirical results show that the estimated coefficient of the spatially lagged dependent variable is significantly positive, indicating that the number of creative firms in a census block is influenced by the number of creative firms in neighboring blocks. This enables to explore the conditions accounting for the concentration of creative industries.
his paper suggests that knowledge externalities influencing the creative firm’s spatial distribution can be interpreted, in an urban scale, in terms of local spatial spillovers, which take the form of spatial dependence. The empirical analysis revealed the existence of a spontaneous creative geography within the metropolitan city of Rome, which is important to further analyse and interpret, if we want to look at the creative clustering from a policy perspective. Creative clusters represent a good opportunity for local governments to catch up with innovation and entrepreneurship policies therefore they need evidence about the existence and the potential role of creative clusters, if they are to encouraging creative industrial growth in particular places. The paper aims to fill the gap between the regional and the urban scale of analysis in empirical studies on creative industries
A GIS Approach to Urban History: Rome in the 18th Century
No full textThis article explores the integration of GIS technology with urban historical studies, focusing on one case study from the 18th century, the project Historical atlas of the modern Rome. The methodology employed in this project allows for effectiveness and accuracy in historical data acquisition and integration, which enables refined analyses of socioeconomic and environmental phenomena. The approach outlined in this article allowed researchers from different disciplines—city historians, archaeologists, demographists, economists, and so on—to interpret urban phenomenologies according to different thematic keys. These interpretations were derived from archival sources that complement each other and offer diversified insights into the urban context. The techniques described in the article are based on methods of data acquisition and spatial analysis developed in a GIS environment by exploiting the effectiveness of this technology in the quantitative treatment of cartographic and documentary sources
Agro romano: un territorio in trasformazione
No full textRome is surrounded by an agricultural region of considerable size, environmentally and economically
relevant and historically tied to the city. The survival of this region and of its agricultural
practices is threatened by the incessant process of urban sprawl and by the incapacity of public policies
to manage effectively the difficult coexistence between urban and rural land uses. The purpose of this
paper is to study the dynamics of transformations taking place in the last decades in the Agro Romano
region, focusing on the characteristics of the structural agricultural endowment. The spatio-temporal
trends in the number and size of firms and of the cultivated areas are analysed with quantitative data
from different sources
Disuguaglianze socio-economiche e trasformazioni urbane nella Roma contemporanea (fine XX-inizi XXI secolo)
No full textSince its proclamation Capital of Italy, the socio-economic conditions of Rome’s population
have proved highly dependent on the distance from the city center and from the characteristics
of urbanization. Physical isolation and social marginalization have been further accentuated
in the age of globalization, in absence of effective public policies aimed at contrasting fast-growing
forms of inequality. The purpose of this paper is to analyse the dynamics of socio-spatial transformations
taking place in the last decades in Rome, focusing on the diachronic variation of
some territorial performance indicators, called territorial markers, used to intercept conditions of
socio-economic centrality and marginality. The analysis is carried out with quantitative data from
different sources, disaggregated at the neighbourhood level
FROM THE SUBSIDIZED MUSE TO CREATIVE INDUSTRIES: CONVERGENCES AND COMPROMISES With a case study in Greater Rome
No full textLa difficoltà di "collocare" le attività economiche derivanti dalla cultura e dalla creatività in un contesto di coerenza ed intelligibilità ha impedito agli studiosi e ai responsabili delle politiche economiche di giungere a conclusioni condivise sui criteri di definizione di questo settore economico. La mancanza di chiarezza nella terminologia raggiunse l'apice alla fine degli anni Novanta, quando le "industrie creative" sostituirono le "industrie culturali", termine fino ad allora ampiamente diffuso e utilizzato nelle politiche culturali nazionali e internazionali. Alla luce dell'intenso dibattito accademico sviluppato attorno alle industrie culturali e creative, la prima parte di questo libro analizza tensioni, dibattiti e divergenze nelle definizioni, nonché le peculiari caratteristiche di queste industrie. Vengono inoltre illustrati gli effetti dell'applicazione di diversi schemi di classificazione del settore culturale e creativo sul suo peso economico, e discusse le difficoltà che esso incontra nella competizione con altri settori per accedere ai programmi di finanziamento europeo. La seconda parte del libro indaga le molteplici relazioni che le industrie creative installano tra di loro e con il contesto urbano. I modelli di localizzazione delle imprese creative vengono analizzati in un caso di studio nella Città metropolitana di Roma. Le distribuzioni spaziali dei diversi settori creativi sono studiate utilizzando punti georiferiti come input per un modello statistico basato sulla funzione K di Ripley. Un'ipotesi nulla di distribuzione casuale viene verificata per le seguenti condizioni: analizzando la distribuzione spaziale di ogni singolo settore creativo rispetto al resto delle attività creative; confrontando a coppie i settori creativi per identificare quelli che rivelano attrazione reciproca; confrontando, per ciascun settore creativo, i modelli di localizzazione delle attività core-creative rispetto alla localizzazione delle rispettive funzioni di servizio. L'analisi empirica ha mostrato che, nella maggior parte dei casi, i settori core-creativi hanno la tendenza di raggrupparsi nello spazio a piccole distanze mentre i rispettivi settori di servizio sono dispersi internamente e disposti attorno al cuore. I confronti reciproci hanno rivelato l'esistenza di cluster creativi urbani caratterizzati dalla coesistenza di diverse attività creative
SPATIAL DISTRIBUTION OF CREATIVE SECTORS: EVIDENCE FROM THE METROPOLITAN CITY OF ROME
No full textThe purpose of this paper is to analyse the location patterns of creative sectors in the
Metropolitan City of Rome. The spatial distribution of firms is studied by utilising spatially
referenced point data as input to a statistical model based on Ripley’s K-function. Pairwise
differences between K-functions of observed point patterns are computed and compared with
simulated confidence bands. A null hypothesis of random labelling is tested upon two
conditions: by analysing the spatial distribution of different creative sectors with respect to
the rest of creative activities and by comparing, for each creative category, localization
patterns of core creative firms with respect to the localization of respective service functions.
The empirical analysis showed that creative sectors have highly different spatial
behaviours, depending on their characteristics and their level of interaction with the urban
milieu. In general, core creative activities in have the tendency to cluster in space at small
distances (up to 20 – 40 kilometres) while the respective service sectors are dispersed
internally and disposed around the core
Analysing spatial relationships through the urban cadastre of nineteenth-century Rome
No full textUrban history and urban cartography are closely linked. The analysis of spatial relationships through cartography enables a deeper and more sophisticated understanding of studied phenomena, and thus can be a valuable support to urban historians. In this context, the eighteenth- and nineteenth-century cadastres represent a fertile ground for experimentation in the quantitative analysis of urban space. The explicit relationships between the descriptive data of the cadastral registers and cadastral maps facilitate the computerization of this historical source and the construction of the spatial database. This article illustrates the use of Geographical Information Systems (GIS) and geostatistical methods applied to urban historical studies, focusing on the analysis of socio-economic information retrieved from the Pio-Gregorian cadastre of Rome, from 1818 to 1824
Geodetic datums of the Italian cadastral systems
No full textThe geodetic datum, and its possible descriptions, of the Italian cadastral networks are analyzed, in order to provide a solution to fit the cadastral sheets to modern map contents and grids, using just their corner crosshair data. Analyzing the extension of the Genova 1902 datum to the whole Italian territory, it occured that the transformation error is acceptable only in the original survey area of the respective triangulation net. For Souther Italy and Sicily (Sicilia), the errors exceed the 20 meters. The Molodensky-type transformation parameters of the Castanea della Furie 1910 and the Guardia Vecchia (Sardinia) datums are provided using only their fundamental point coordinates, without error estimation. While these datums are not correctly checked at their whole application are, we suggest to define local datums of the Bessel ellipsoid, using the Bessel and WGS84coordinates of the respective cadastral grid origins and use them for geo-reference as a basis of the local Cassini grids
