Una finestra sul giardino: pittura romana in frammenti dal quartiere abitativo di Roselle
No full textFrom the residential neighborhood to the “pendici della collina nord” of Roselle comes a set of wall painting fragments that shows a large window overlooking illusionistically on the garden. The scene, bordered by marble transenna, is made up of colorful birds, a basket filled with cherries and a cake of fruit and cheese. The evident blend between the typical repertoire of garden painting and the features of the still life paintings or ornaments of the II style speak for a phase of transition to the creation of a genre or rather of its peripheral processing, in part misunderstood, by the high-class rosellan class
The early Roman pottery kilns in the ager Rusellanus (southern Tuscany, Italy) and their products
No full textThis archaeometric research examined the structural elements of the three kilns found in the plain below the archaeological site of Rusellae, the ceramics found within this artisans' quarter and the clayey materials on which the workshops were built. Twenty-one samples were investigated by bulk chemical and mineralogical analyses (ICP-MS, ICP-AES and XRD) and mineralogical-petrographic analyses on thin sections (optical microscopy and scanning electron microscopy). The results allowed the characterisation of the production group to be obtained. Both carbonatic and non-carbonatic clayey materials were used to make common-ware ceramics and, above all, building materials such as bricks and tiles. The production technology varied from accurately to poorly worked pastes, fired from low (about 800 degrees C) to very high temperatures (above 1100 degrees C). The compositional comparison with data previously obtained on stamped bricks and neighbouring clayey materials suggested a correlation with the producer/s known by the stamps SEX CLEMENT/PROBI and PROBI. Furthermore, the variety of raw materials used in the manufacture and product diversification also let speculate that the production site welcomed various artisans and products for the final firing
Il Progetto Roselle 2018-2020: gli scavi sulla “Tempelterrasse”
No full textThis work proposes the first results of the excavation activities carried out in the framework of the Project devoted to the urban area of Rusellae. The Rusellae Urban Area Project takes its origin by the strict collaboration that the city of Grosseto local government, through the Archaeology and Art Museum of Maremma, the Archaeological Superintendency and the Department of History and Cultural Heritage of the University of Siena, began since 2013 in order to create a deepener link between Grosseto and its main archaeological and monumental site. An excavation in concession has therefore been organized in the years 2018-2020, with the aim of widening the monumental heritage and of improving the criteria to visit the site. At the same time, the massive bulk of unpublished data, recovered from regular excavations carried out at Rusellae after the Second World War, are still waiting a reasoned edition plan, that will help the interpretation of the different periods (Protohistoric, Etruscan, Roman and Medieval) of occupation of the site.
New diggings have been promoted in 2018 on the so-called Tempelterrasse, a site placed on the southern hill of the city. The Tempelterrasse has been so named by the existance of massive terracing walls, supporting the upper plateau of the hill, highlighted by the research campaigns conducted by the German Archaeological Institute in 1957-1958. These walls were reputed to retain the area of a sanctuary, whose possible presence had been supposed by the discovering of abundant Late-Archaic and Hellenistic architectural terracottas, recovered in the filling of the rooms composing the retaining walls. The 2018 diggings have confirmed the existence of the cult of the deity Artemis, in the Etruscan version of Artames/Artumes, witnessed by an epigraph carved on the foot of an Attic cup, dating to the full 5th century B.C
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
