Representing the territory: the layer The landscape as it was of WebGIS visualversilia.com
No full textIl presente contributo illustra la metodologia messa in atto durante la realizzazione del progetto di ricerca VisualVersilia, condotto dal centro e-GEA, per la creazione di una guida multimediale su WebGis (visualversilia.com), in grado di mappare, studiare, leggere e conoscere il territorio, ricostruirne la storia e le trasformazioni, restituire la complessità e la ricchezza del patrimonio culturale attraverso la documentazione scritta e archeologica, la cartografia storica e contemporanea, le fotografie d’archivio e moderne, le immagini satellitari, i progetti urbanistici, le pitture e i disegni di artisti che hanno ritratto il paesaggio versiliese. La metodologia di ricerca adottata e l’impiego delle nuove tecnologie hanno dunque consentito di creare una guida in grado di fornire un modo nuovo di visualizzare, raccontare, valorizzare il territorio della Versilia, di condurre l’utente alla scoperta di un territorio e delle sue realtà culturali attraverso il tempo e lo spazio; lo strumento del WebGis consente di localizzare, rappresentare e gestire i dati relativi agli elementi storico-culturali del territorio, attraverso una mappa interattiva che presenta una serie di livelli informativi divisi per temi ed epoche. Nello specifico il livello “Il paesaggio com’era”, a sua volta articolato in sottolivelli e caratterizzato da ricostruzioni della geografia e delle infrastrutture della Versilia in età preromana, romana, medievale, moderna e contemporanea, permette di muoversi in uno spazio/mappa, di immergersi in realtà temporali diverse e di contestualizzare i siti culturale presenti sul territorio nello spazio geografico relativo all’epoca alla quale appartengono
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
False perspectives on human language: Why statistics needs linguistics
Full text linkA sharp tension exists about the nature of human language between two opposite parties: those who believe that statistical surface distributions, in particular using measures like surprisal, provide a better understanding of language processing, vs. those who believe that discrete hierarchical structures implementing linguistic information such as syntactic ones are a better tool. In this paper, we show that this dichotomy is a false one. Relying on the fact that statistical measures can be defined on the basis of either structural or non-structural models, we provide empirical evidence that only models of surprisal that reflect syntactic structure are able to account for language regularities
Asymmetries in nominal copular sentences: Psycholinguistic evidence in favor of the raising analysis
No full textThis work explores two kinds of asymmetries within the class of nominal copular (NC) constructions under the unified theory of copular sentences deriving the two basic configurations from a unique underlying structure via raising, namely canonical vs. inverse. Using acceptability judgments, we first tested wh- sub-extraction from both determiner phrases (DPs) in both configurations. We then collected acceptability for the same sentences without involving sub-extraction, and compared these results with the acceptability of pre- and post-verbal subject placement in transitive, unergative and unaccusative predicates. We observed the following. (i) Sub- extractions from predicates in canonical form are the most acceptable. (ii) In the remaining conditions, sub-extractions from predicates are more acceptable than those from subjects, and those from canonical are more acceptable than those from inverse NC sentences. The preference for canonical NC sentences is also confirmed when sub-extraction is absent. (iii) There is a general preference for preverbal subjects with all verbal predicates (especially strong in transitive and unergative predicates, milder with unaccusatives). The best acceptability results obtained with sub-extraction from predicates in canonical form are in line with the unified theory; the necessity to occupy a pre-verbal position for (presuppositional) subjects captures all the major remaining contrasts
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
Sardinian Territories as Told By Google Street View: the “ISPERIADAS” Project
Full text linkIn this paper, I would like to consider some geographical implications of Google Street View and more precisely of Isperiadas - Sardigna Street View a photographic project about the contemporary Sardinia began on 2012. The peculiarity of Isperiadas – the use of Google Street View as a source to tell the contradictions and trans-formations facing Sardinian territory – triggers questions concerning the possibility that the new technologies can help us build original narratives, which are different from the official ones and at the same time respectful of the complexity of the territories. These are clearly open matters (to which it is unthinkable to give a final and complete answer), and with which we have been dealing for not long
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
