Il progetto “Le rotte del marmo nel mondo antico” e la circolazione dei marmi bianchi nel Mediterraneo romano
No full textWe present the preliminary results of the study of the cargos with white marbles in the project “The routes of the marble
in Antiquity”. Aim of this research is to reconstruct the traffics and the characteristics of the ships involved in this special
transportation. We have surveyed four shipwrecks carrying Prokonnesian marble, and few elements of other white mar
bles (Dokimeion, Pentelic and Lunense), and three sites with Lunense marble which allow to reconstruct the routes of
these cargos in the central Mediterranean. The marble is always transported as raw blocks or raw columns also of very big
size, but, in few cases, half worked objects (bases and thin slabs) can be present in the cargo. The size both of the cargos
and of the marble elements suggest that often they had to be destined to the construction of big public buildings.
The size of the ships can reach 40 m of lenght and 350 tonns of cargo which is close to the Late Republican onerariae
transporting wine from central Italy to Gallia but much more of the other ships known belonging to the Imperial period.
The chronology of the shipwrecks is III century AD for the cargos of Prokonnesian and I-II century AD for the cargos of
Lunense, although these last contexts are still under investigation. The scarcity of pottery in the sites does not facilitate the
dating and the reconstruction of the routes which is often difficu
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
