The Lothal Sealings: records from an Indus Civilization town at the eastern end of the maritime trade limits across the Arabian Sea.
The paper provides the first detailed typology and functional study of the approximately one hundred terracotta sealings discovered at the Harappa site of Lothal (Gujarat, India). The study is based on the physical reexamination of the sealings and on new high resolution digital photographs taken by the authors, who analyzed in great detail the traces left by the containers on the back of the sealings. This approach allowed outlining similarities and differences with contemporary sealing systems used in Mesopotamia and the Near East, and discussing the role played by Lothal in the commercial networks across the Arabian Sea
Ras al-Hadd HD-1. L’Approdo delle Grandi Civiltà del Terzo millennio | Ras al-Hadd HD-1. The Harbor of the Great Civilizations of the Third millennium
Rinvenuto nell’ambito del “Joint Hadd Project” nel 1986, il complesso archeologico di HD-1 a Ras al-Hadd si segnala per la presenza di un gran quantità di ceramica della Civiltà dell’Indo (seconda metà del terzo millennio a.C.) e costituisce un eccezionale contesto per comprendere le interazioni tra la Penisola Araba e la Valle dell’Indo nel più ampio quadro degli scambi tra la Mesopotamia e il Subcontinente Indo-Pakistano.HD-1 represents an exceptional context for understanding the interactions occurred between the Arabian Peninsula and in Indus Valley in the larger picture of the exchanges between Mesopotamia and the Indo-Pakistani Subcontinent. Twenty years after the first explorations conducted by the British Museum, the current research started in 2016 aims at implementing an updated palaeobiological sampling and a detail analytical study of the production activities
The Early Iron Age collective tomb LCG-1 at Dibba al-Bayah, Oman: long-distance exchange and cross-cultural interaction
The 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
New excavations at the Umm an-Nar site Ras al-Hadd HD-1, Sultanate of Oman (seasons 2016-2018): Insights on cultural interaction
Renewed excavations in 2016-17 and 2017-18 at the Umm an-Nar coastal site HD-1 at Ras al-Hadd, in the Sultanate of Oman, provide new insights on regional and long-distance interactions during the Early Bronze Age. The Italian-American 'Joint Hadd project' is led by Maurizio Cattani from the University of Bologna, and Jonathan Mark Kenoyer from the University of Wisconsin-Madison, under the auspices of the Ministry of Heritage and Culture of Oman. New radiocarbon dates place the site firmly in the mid-third millennium BC. Plant and faunal remains are being examined to determine seasonal subsistence patterns and fishing strategies. The discovery of lithic, copper, and shell manufacturing debris provides new information on local technologies. Fibres and textiles preserved on copper tools and other artefacts reveal the nature of local fibre production and possible long-distance trade of other fibres. Finished stone beads of local as well as non-local materials indicate the importance of both regional and external trade. A wide variety of local as well as Indus-related ceramics reveal connections to regional Umm an-Nar communities and the more distant Indus source areas. Preliminary results of selected artefact analyses are presented here to highlight new directions for research
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
