No full textDuring the 2018 field season of the Necropilis of Poggio Gramignano - Lugnano in Teverina (Italy), a remarkable discovery was made. In the early afternoon under the beating July sun, while the cicadas sang out from the old oak tree looming over the villa’s ruins, the archaeologists involved in the project began to reveal the first signs of a new burial. Amphorae sherds capped a tegula (roof tile) leaning up against one of the storage magazine’s walls. But as excavation continued, it became clear to all that this burial was different. Not long after Gabriele and Danny had come across the first signs of this burial, the two had fully uncovered a partial “alla cappuccina” style burial, much larger than those so far discovered at Poggio Gramignano. Alla cappuccina burials are typical of this cemetery and Roman Italy in general, in which tegulae are stacked and pitched against one another to create a make-shift tomb, often for ordinary individuals. This was a partial alla cappuccina burial, constructed by leaning two large roof tiles against an existing wall of the room. Beneath the tegulae was found the remains of a single individual placed resting on the left side and facing the wall of the room. Designated as “Burial 51,” this individual and the burial are remarkable for two reasons. First, this child is much older than those infants and children so far discovered (52 in total). Based on the stage of dental development evident, this young child (whose sex remains undetermined at this moment) was around 10 years old at the time of its death. While the body had been subject to some taphonomic disturbance over time, it was well-protected by the tegulae, evidenced by the skeleton’s completeness and the high degree of articulation. This preservation made the second remarkable fact of this burial all the more apparent. A stone was found within his or her mouth. This stone was revealed to be a small limestone cut in a shape similar to a wall cubilium. A cubilium is a kind of cut stone crafted by the Romans, pointed on end and inserted into stone-faced cement walls. Because of the way the child’s head was positioned, the jaw would not have fallen open as the masseter muscles decomposed, suggesting that the placement of the stone was intentional and did not result from the slow collapse of the surrounding edifice. Moreover, this stone had cement on two sides, in which small tooth-shaped depressions are visible, lending further weight to the interpretation that the stone was purposefully inserted within the child’s mouth
Preliminary Report of the 2016 Excavation of La Villa Romana di Poggio Gramigano at Lugnano in Teverina (Umbria), Italy
No full textIn 2016 a new excavation of the Roman villa and the infant cemetery of Poggio Gramignano (Lugnano in Teverina, Italy) began. This contribution is a preliminary report of the first excavation season. In 2016, between June and July, new excavations at la Villa Romana di Poggio Gramignano (VRPG) began. This was the first season in a multi-year research project - a partnership between the Soprintendenza Archeologia Belle Arti e Paesaggio dell’Umbria, the University of Arizona, Yale University, Stanford University, and the Commune di Lugnano in Teverina. This project aims to better understand the villa and its surrounding area, with particular focus on the late Roman infant cemetery discovered within the villa’s storage magazines. The project continues work begun over three decades ago. Initial excavations of the villa were conducted by Daniela Monacchi of the Soprintendenza Archeologia Belle Arti e Paesaggio dell’Umbria, from 1982 to 1984. David Soren (University of Arizona) directed subsequent excavations, from 1987 to 1994, in collaboration with the Soprintendenza Archeologia Belle Arti e Paesaggio dell’Umbria (Soren and Soren 1999)
New research in the Roman villa and late Roman infant and child cemetery at Poggio Gramignano (Lugnano in Teverina, Umbria, Italy)
No full textBegun in the Summer of 2016, the Villa Romana di Poggio Gramignano Archaeological Project – a partnership between the Soprintendenza Archeologia dell’Umbria, the University of Arizona, and the town council of Lugnano in Teverina – continues a work initially begun in the 1980s. The present report illustrates the preliminary results obtained after the years of excavation 2016-2019. The aim is to contribute to the debate concerning the causes of the end of Roman villas in the western part of Empire
Strumenti, tecniche e Soluzioni Open Source a confronto per l’elaborazione fotogrammetrica delle immagini digitali in ambito archeologico
Get PDFThis work wants to be an overview about the various “open source” software that can be used to obtain rendering and photogrammetric data geo-referenced from digital photos. In fact, all the phases of digital photogrammetric processing can be performed by open source software. This paper, therefore, wants to provide an alternative to the use of the most famous commercial photogrammetric software, taking into consideration and comparing the different methods of photogrammetric processing available in the open source environmental to obtain the final aims pursued and showing off how it is possible to integrate the information coming out the different software used in order to the best result possible. The software used were: MicMac, OpenMVG, CloudCompare, MeshLab, Qgis2.8 and GrassGIS7. The comparison between the different photogrammetric processings through the software mentioned above has been tested on a burial in “enchytrismòs” found out during the archaeological excavations in the site of Poggio Gramignano (Italy). Generally the main final results we can obtain from a photogrammetric survey are: 1. a 3d model of the area or og the object investigated in the form of a “dense points cloud” rendered with associated texture; 2. a Digital Surface Model (DSM); 3. an orthophoto. These results can also be geo-referenced in a geographic reference system and can be used for many different purposes in the light of the kind of the research carring out. Even in this case, therefore, we worked on reaching the same final results that the “open source” software used allowed to obtain, resulting in a very hight reliability. Moreover, the final outputs can be managed and used to obtain, in the GIS environment, further data such as sections, altimetric profiles and so on and to associate them a database in order to have alphanumeric information for every vectorial element
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
