Estimation of increasing urbanization trend in the Frascati DOC wine area: a geostatistical analysis approach
Full text linkIl presente lavoro di tesi raccoglie i dati di alcuni progetti di ricerca svolti sulle pratiche agricole, in particolare vitivinicole, in un area a sud-est di Roma, conosciuta come area dei Castelli Romani.
Queste informazioni sono state analizzate in rapporto alla crescita urbana della periferia del comune di Roma e dei comuni di prima fascia, inseriti nel confine dell’ area di produzione del vino DOC Frascati . Il lavoro si è poi concentrato su una metodologia di indagine per caratterizzare i vari comuni compresi nell’area di produzione DOC; per questo è stato elaborato un indice di profilo dell’area (APindex) che oltre a definire le caratteristiche di un comune rispetto ad un altro, ha permesso di fare delle previsioni temporali sullo sviluppo urbano a scapito delle colture agricole.This thesis collects data of some research projects on agricultural practices, particularly wine, developed in an area south-east of Rome known as the Castelli Romani area.
This set of information was analyzed in relation to urban growth on the outskirts of the town of Rome and the municipalities of the first ring, inserted in an area of the Frascati DOC wine production. The research work was then concentrated on a methodology of investigation on the characterization of the various municipalities in DOC production.
It was therefore prepared a profile of the index (APindex) which in addition to precisely define the characteristics of a municipality than another, allowed to make predictions about the future of urban development to the detriment of agricultural crops
Spatial analysis of the increasing urbanization trend in the Frascati wine designation of origin (DOC) area: a geostatistical approach
No full textThis work refers to the design, test and implementation of an estimation index useful to describe cultivated
areas reduction in a sub-urban context. The index is based on the historical analysis of the interference
between urban development and agricultural activities, and it uses geostatistical methods. The necessary data
to implement the index has been derived from heterogeneous sources covering a period of about 10 years
(1996 to 2005). Joint use of optical satellite images at high/very high spatial resolution and numerical
cartographic data has been essential. More in detail, the index has been tested in the estimation of land use
changes for the period of 2005 to 2008 in the study area. Results have been verified through a very-highresolution
(VHR) Kompsat 2 satellite image acquired in 2008
Proposta di una metodologia di analisi del rischio territoriale
No full textL’obiettivo del lavoro è l’identificazione dei livelli di “rischio territoriale”, di
tipo ambientale, ottenuti confrontando parametri urbanistici con alcuni parametri geo-morfologici, quali le formazioni geo-litologiche e l’acclività: per raggiungere tale scopo si è presa in esame, come area di studio il bacino del lago di Nemi.
Si è costruito, quindi, un modello di rischio utilizzando un sistema informativo
GIS: in tale sistema sono state inserite e geo-referenziate le informazioni desunte da dati satellitari e da diversi livelli cartografici relativi alla struttura geologica e morfologica del territorio in esame. I livelli di rischio
vengono restituiti attraverso un indice che registra la vulnerabilità del territorio sulla base valutativa dei fenomeni basati sui connotati geo-morfologici opportunamente corretti tenendo conto di alcune variabili
pregresse.
Si è elaborata una “feature class” di rischio dalla quale e’ stata estratta una
“carta di rischio” e si è, poi, confrontato il modello ottenuto con la consistenza edilizia attuale ed infi ne, in proiezione, si sono vavalutate
le previsioni urbanistiche dei piani regolatori del comune di Nemi e di Genzano.
La classificazione dei valori dell’indice in diversi ranges ha permesso di valutare la portata del rischio rispetto alla urbanizzazione del territorio
Infiltration galleries, ancient constructions and geology integrated in the landsscape of Nemi Maar (Alban Hills, Roma, Italy)
No full textIn the basin of Nemi Maar some aspects of the engineering of the territory that represent a landscape value can be identified. These aspects are represented by hydraulic structures for collection and distribution of water which are part of the physical structure of the study area. It is also well known that other sources of water were very abundant until the second half of the twentieth century. Waters are collected in filtering galleries, fountains and springs located in many parts of the territory. This investigation concerns the study of the system of underground drainage channels. This capillary system rediscovered, completed and maintained over the centuries (the oldest tunnels are dated back to the fifth century A.C.), has been preserved until today, demonstrating its ingenious functionality. The final aim of the study has been the realization of a Geographic Informative System (GIS), where all the hydraulic, geological and archeological data are in relation between them. The informative system is open and can be questioned on several levels of knowledge by providing cognitive data

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
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
