Siti archeologici a rischio di erosione nella Laguna di Venezia: evoluzione geomorfologica e popolamento antico
No full textLa laguna di Venezia sta subendo un costante
e preoccupante fenomeno di erosione
delle barene e dei margini interni
lagunari sia a causa dell’innalzamento
del livello marino che per effetto del moto ondoso
e delle trasformazioni indotte alla dinamica
delle acque lagunari. L’ambiente lagunare
veneziano presenta delle condizioni di
rischio da erosione nei confronti del patrimonio
archeologico particolarmente importanti
e assume dei caratteri che lo differenziano
dagli altri ambienti più propriamente costieri.
Per comprendere le modalità di interazione
tra dinamiche naturali e sviluppo dell’insediamento
è necessario conoscere i modi in
cui si è realizzata la morfogenesi lagunare e
come l’Uomo abbia interagito con la laguna,
specialmente in rapporto al mutare tra spazi
acquei e terre emerse. La ricerca, che si è
avvalsa del metodo multidisciplinare messo
a punto e già applicato nella elaborazione
della carta geomorfologica della Provincia di
Venezia (Bondesan, Meneghel, 2004), della
carta delle Unità geologiche della Provincia
di Venezia (Bondesan et al., 2009) e della
Carta delle unità di paesaggio geo- archeologiche
della Provincia di Venezia (Furlanetto,
2008, in stampa, c), ha coinvolto l’archeologia,
la cartografia storica, la geomorfologia
e la geologia

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
