Neolithic and Early Bronze Age Occupations at Ras Al-Hadd HD-5, Sultanate of Oman
No full textThe archaeological site of HD-5 is located at Ras Al-Hadd (Ash-Sharqiyah Governorate, Sultanate of Oman), on a rocky hill facing the sea, 1.6 kilometer north of the large Hafit site of HD-6. In four campaigns, from 2010 to 2015, an 11 x 10 m area was explored using a micro-stratigraphic approach for the excavation of the loose sandy layers that formed the deposit. The excavation revealed two main occupation phases divided by a frequentation gap, a late Neolithic one in the 4th millennium BC and the other at the end of the 3rd millennium BC. The Neolithic occupation included a series of human depositions along the northern side of the explored area
Shell fish-hook production at Ras al-Hadd HD-5, Sultanate of Oman (fourth millennium BC): preliminary archaeological and experimental studies
No full textThe paper presents the preliminary archaeological study of around 200 artefacts related to the production of shell fish-hooks made from Pinctada sp. discovered at the Neolithic coastal site of Ras al-Hadd HD-5 in 2014. The site occupation dates to the fourth millennium BC and finished shell hooks and manufacturing debris were recovered from stratigraphic contexts that included primary floors and workshop dumps. The artefacts include complete shells that were probably collected from the nearby lagoon, hammer stones and rasps made of sandstone, and all stages of the shell-hook manufacturing processes. After comprehensive documentation and study of the artefacts, experimental replications were carried out to gain a better understanding of the stages of production and factors that contributed to breakage and discard. Future studies will include the use of experimental hooks to determine their strength and durability. Excavations were conducted by a team from the University of Bologna under the auspices of the Department of Excavations and Archaeological Studies, Ministry of Heritage and Culture, Sultanate of Oman
Another side to the story. Preliminary results from the renewed excavations on the eastern flank of Tell Abraq (2021-2022)
No full textExcavations on the eastern flank of Tell Abraq, within the territory of the emirate
of Umm Al Quwain, during the 2021 and 2022 field seasons, yielded remarkable results that help to better understand how the site was occupied in the second half of the 2nd and throughout the 1st millennium BCE. Evidence for several phases in the site's occupation is connected with buildings and features characterised by largely differing architecture, dimensions and associated materials, before a final switch (in the Late Pre-Islamic period) to the funerary use of the area, with several burials that were likely the target of later robbing. Scattered artefacts, comprising exceptional items unique in the UAE, might be referred to the original inventory of these graves, as contemporary architecture has not been discovered so far. Some of these artefacts illustrate the strong influence of foreign productions conveyed both overland from South Arabia and oversea, via Characene, during the first centuries CE
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
