A solution to the problem of the cartographic generalization of Italian geographical databases at large-medium scales: approach definition, process design and operators implementation
No full textDuring many years in which the generalization of cartographic data has been studied many developments have been achieved. As some national mapping agencies in Europe and in the world are beginning to introduce automated processes in their production lines, the original dream of a completely automated system that could perform generalization is getting closer, even though it has not been reached yet.
The aim of this dissertation is to investigate whether it is possible to design and implement a working generalization process for the Italian large-medium scale geographical databases.
In this thesis we argue that the models, the approaches and the algorithms developed so far provide a robust and sound base to the problem of automated cartographic generalization,
but that to build an effective generalization process it is necessary to deal with all the small details deriving from the actual implementation of the process on defined scales and data models of input and output.
We propose/speculate that our goal can be reached by capitalizing the research results achieved so far and customizing the process on the data models and scales treated.
This is the approach at the basis of this research work: the design of the cartographic generalization process and the algorithms implemented, either developed from scratch or deriving from previous works, have all been customized to solve a well defined problem: i.e. they expect input data that comply to a consistent data model and are tailored to obtain the results at defined scale and data model.
This thesis explains how this approach has been brought into practice in the frame of the CARGEN project that aims at the development of a complete cartographic process to generalize the Italian medium scale geographical databases at 1:25000 and 1:50000 scale from the official Italian large scale geographical database at 1:5000 scale. This thesis will focus on the generalization to the 1:25000 scale, describing the approach that has been adopted, the overall process that has been designed and will provide details on the most important operators implemented for the generalization at such scale.Questa tesi di dottorato sviluppa la problematica della generalizzazione cartografica applicata ai database geografici italiani alla alta e media scala. Il lavoro di ricerca si è sviluppato all'interno del progetto CARGEN, un progetto di ricerca tra l'Università di Padova e la Regione Veneto, con la collaborazione dell'IGMI per lo sviluppo di una procedura automatica di generalizzazione del database DB25 IGMI in scala 1:25000 a partire dal database regionale GeoDBR in scala 1:5000.
Il lavoro di tesi affronta tutte le tematiche relative al processo di generalizzazione, partendo dalla generalizzazione del modello fino alla descrizione degli algoritmi di generalizzazione delle geometrie
Film and Tourism. An Information System for Disclosing the Cinematographic Attractiveness of Destinations (Giulia Lavarone pp.289-291)
Full text linkThe Department of Cultural Heritage of the University of Padova investigated the topic of film-induced tourism in a year-long project, concluded in April 2015, titled Strumenti innovativi per la promozione turistica: film-induced tourism (Novel Tools to Promote Tourism: Film-induced Tourism). The project was financed by the Veneto Region through ESF funds. It brought together the expertise of film scholars, computer scientists and destination management experts, in partnership with public bodies (Provincia di Padova) and ICT companies. The goal of the project was to develop an information system that fosters film-induced tourism combining data about a geographical area and the movies produced in it. The system is designed as a platform to store and convey rich contents, able to address the needs of the tourist but also of stakeholders as DMOs and film commissions. The system was planned as a model for the destinations which could take advantage of a significant cinematographic background, yet are unlikely to spontaneously produce considerable film-induced tourism phenomena. The province of Padova has been used as a case study
Searching and Exploring Data in a Software Architecture for Film-Induced Tourism
No full textFilm induced tourism is a recent phenomenon, rising increasing interest in tourism management and promotion. A research project on this topic has been recently investigated at the Department of Cultural Heritage of the University of Padua, resulting in the development of a software architecture for the promotion of film-induced tourism, capable of storing and providing rich information about the movies produced in a selected geographic area. This paper presents the design and implementation of the solutions developed to search and explore the data stored in the software architecture
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
