No full textLe aree di dissesto idrogeologico coprono circa il 7% del
territorio italiano, in particolare la Regione Emilia Roma-
gna risulta essere una delle tre regioni a più alto tasso
di dissesto in quanto oltre il 20% del territorio collinare
e montano è interessato da accumuli di frane attive o
quiescenti (dati progetto nazionale IFFI, Inventario dei
Fenomeni Franosi in Italia). In tale contesto un corretto
ed efficace monitoraggio di questi fenomeni da parte dei
diversi Enti preposti risulta essere un’attività sempre più
importante e necessaria sia per i settori inerenti alla pro-
tezione civile, che per quelli riguardanti la pianificazione.
Le moderne tecniche di monitoraggio possono fornire ri-
sultati molto interessanti per il controllo di tutte le defor-
mazioni che avvengono all’interno di un’area in dissesto.
Tali informazioni possono essere facilmente integrate
con quelle dedotte utilizzando le tecniche più classiche
come ad esempio estensimetri e/o i rilievi topografici,
e/o correlate con altri tipi di rilievo, come ad esempio le
misure eseguite utilizzando pluviometri o piezometri.
Nella prima parte del lavoro sono descritte brevemente
le principali caratteristiche delle metodologie di moni-
toraggio geofisico satellitare, aeree e terrestri. In parti-
colare, sono descritte le diverse modalità di rilievo che
possono essere eseguite utilizzando la metodologia
GNSS e le precisioni raggiungibili. Di seguito è descrit-
ta un’interessante applicazione in relazione alla grande
frana di Patigno, un’area di dissesto idrogeologico tipica
dell’Appennino settentrionale ubicata nel comune di Zeri
in provincia di Massa Carrara (Fig.1)
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
