Bakchias alla luce delle ultime scoperte: topografia e urbanistica
No full textThe latest studies of the Bologna University about the scientific expedition at Bakchias (Kom Umm el-Atl), carried out in collaboration with "Sapienza" Rome University, have revealed several new elements useful for reconsidering the urban development of the kome. The archaeological research was completed by a topographical survey; all data were managed in a GIS database, an important tool for the analysis and interpretation of spatial information, in order to investigate the site historical evolution
Diachronic Development of a Settlement in the Fayyum Region: Bakchias in Ptolemaic and Roman Times
No full textThe scientific expedition of Bologna University has excavated at Kom Umm el-Atl, the ancient Bakchias, in the north east of
the Fayyum, for over twenty years. In particular, the latest studies, accomplished in collaboration with Sapienza University of
Rome (since 2005), have revealed several new elements which are useful for reconsidering the urban development of the kome.
The on-field archaeological research has brought to light numerous structures, both public buildings and private houses, and it
has been completed by an intra-site survey and an important review of the papyrological sources, useful for reconstructing the
Bakchias topography and landscape. All the data thus obtained were merged together in a GIS environment, in order to collect
and manage all the information and to integrate the individual elements into a coherent workflow process.
Thanks to these important activities undertaken by the Bakchias team, it has been possible to compile diachronical maps of the
town and to outline the site’s evolution during the Ptolemaic and Roman period
Scavi di Suasa II. La necropoli orientale.
No full textFra il 2012 e il 2016 è stata riportata in luce a Suasa, municipio romano nell’entroterra di Senigallia oggetto di ricerche da parte dell’Università di Bologna da oltre trent’anni, una necropoli che si va ad aggiungere alle altre tre già note e che trae il nome dalla sua posizione rispetto all’abitato. Il suo lungo utilizzo, protratto per almeno sei secoli tra l’età repubblicana e la piena età imperiale, e la sua collocazione topografica a cavallo di uno degli assi generatori della città, rendono questo contesto particolarmente significativo.
Lo studio della Necropoli Orientale di Suasa è stato occasione di confronto tra studiosi con competenze diverse, che spaziano dall’archeologia, all’antropologia e all’archeozoologia, sino alle analisi paeloambientali, aggiungendo un tassello importante alla ricostruzione del paesaggio funerario.
Grazie a questo approccio integrato è stato possibile ricostruire i gesti e la fisionomia di una comunità romana dell’area medio-adriatica
The Egyptological research activities of Sapienza University of Rome. From archaeology to topography and beyond
No full textThe Egyptological research of Sapienza Università di Roma includes a
variety of activities and fieldworks: from the archaeological expedition at Bakchias (26th dynasty-Late Antiquity), a settlement located in the Fayyūm region, to the study of the transformation of religious space from pharaonic to Christian period, to the realization of a digital archaeological atlas of Coptic literature that aims at exploring and representing the process of production, copying, usage, dissemination, and storage of Coptic works in relation to the geo-archaeological contexts of origin of both the texts themselves and their related writing supports. This article summarizes the main goals of all these projects and the main scientific results achieved until no
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
