The softstone vessels assemblage from the Long Collective Grave 1 (LCG-1) at Dibbā al-Bayah (Sultanate of Oman): A preliminary assessment
Get PDFThe present contribution aims to provide an overview of the large collection of soft stone vessels and lids coming from the collective tomb Long Collective Grave 1 in the Dibbā al-Bayah funerary complex, along with a brief description and evaluation of the tomb itself. The corpus of material here discussed has been recovered during the 2012 season, and it mainly encompasses the chronological span between the second and first millennium BC. The findings are classified and organised in tables according to their chronological phase, and successively on the basis of their morphology and decorative patterns to which a major focus is addressed. Given the outstanding manufacturing of the materials, the finely incised and even plastic decorations, and their state of preservation, an assessment of such remarkable corpus, although partial, contributes significantly to the study of the diffusion and production of stone vessels in South-East Arabia

No full textThe Early Iron Age collective tomb LCG-1 at Dibba al-Bayah, Oman: long-distance exchange and cross-cultural interaction
Get PDFThe Iron Age (c. 1300-600 BC) of South-eastern Arabia is characterised by rapid expansion of settlement. Social structures formed over the previous millennia, however, persisted and were reinforced through the development of collective funerary monuments. A recently discovered tomb of Late Bronze to Early Iron Age date at Dibba al-Bayah in the Sultanate of Oman has yielded a range of artefacts that illuminate the nature and extent of the long-distance contacts of the local community. Seemingly selected not only for their exotic appeal, but also for their apotropaic function, these objects testify to a deep cross-cultural knowledge extending across the wider region during this crucial period in Arabian prehistory

La frequentazione cultuale della Grotta di San Biagio (Ostuni-Brindisi)
No full textTra i materiali provenienti dai livelli di Grotta San Biagio (Ostuni-BR), indicatori di varia natura avvalorano l’ipotesi che il sito fosse frequentato per scopi cultuali e rituali in un periodo compreso tra la metà del VI e la metà del III millennio. In questa comunicazione si presentano alcuni dati riferibili alla frequentazione neolitica della grotta acquisiti durante i recenti scavi condotti dall’Università di Bologna. Le ricerche hanno consentito di individuare, oltre alla presenza di focolari e buche, un grande recinto di pietra -sulla scorta dei noti esempi di Cala Scizzo e Grotta Pacelli. La presenza della raffinata ceramica di facies Serra d’Alto, in associazione con i già noti oggetti estranei alla sfera del quotidiano come la pintadera, l’idoletto a testa di papero e le accettine in pietra verde, costituiscono una chiara testimonianza dell’utilizzo della cavità a scopi cultuali
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
