I nuovi scavi a Villa Santa Marina
Nel lavoro si presentano i risultati dei saggi archeologici effettuati in località S. Marina, Petralia Soprana (PA) negli 2013 e 2014, nell'area di una villa rustica di età romana. Si sono individuate due fasi di uso di alcune strutture che circondano un grande cortile porticato su un lato: la prima di età imperiale; la seconda post antica (necropoli)
Da Hykkara a Qarinis. Evoluzione di una statio tardoromana lungo la Via Valeria
The settlement of S. Nicola in Carini (Palermo, Sicily), identified with the statio of Hykkara along the via Valeria, mentioned in the Itinerarium Antonini, also presents an Islamic age phase. The catacomb of Villagrazia, used from the 4th to the full 7th century, and the Ecclesia Carinensis are related to the Late Roman settlement. The archaeological investigations, started by the Soprintendenza BB.CC.AA. of Palermo in 1997 and 2005, resumed in 2016 with systematic excavations, thanks to the availability of the Municipality of Carini and the collaboration of the ArcheOfficina Society. Since 2021 an agreement has been signed between Soprintendenza, Municipality of Carini and University of Palermo. The excavations have uncovered a domus of the 4th-5th century A.D. with later modifications. Until the 7th century, imports from North Africa prevail; while in the Early Middle Ages, finds relating to the first phase of the Islamization of Sicily are more present. New data will be provided by ongoing geophysical surveys
Relazioni tra geomorfologia, processi post-deposizionali e visibilità del suolo nella lettura dei dati di prospezione archeologica
This paper takes into examination two different districts of the vast area investigated by the archaeological survey of the hinterland of the ancient Greek colony of Himera: the coastal area between the northern Imera and Rocella rivers and the hilly watershed zone located between the northern Imera, southern Imera and Platani rivers. The study examines the relationships between geomorphology, post-depositional processes and visibility of the ground and their impact on the interpretation of data collected during the archaeological survey and, consequently, on the historical reconstruction of the population of the territory from Prehistory to the Middle Ages. Three aspects in particular have been taken into consideration: a) the impact of geomorphology on the recognition of archaeological traces; b) the relationship between geomorphology and visibility of archaeological finds; c) the role of the geomorphological and/or of the human factors in the selection of areas to be settled. Our conclusion is that the geomorphological context assumes a major role in the selection of areas of settlement, while the visibility of the ground seems to affect not only the number of archaeological finds, but also their legibility and interpretation
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
