Low cost digital tools for archaeology
No full textModern technology offers elaborated and efficient instruments capable of performing extremely accurate surveys of architectural and archaeological remains. However, not all of them can be used everywhere: archaeological missions might be constrained by logistics, environmental and, especially, financial restrictions. This issue is especially felt by archaeological missions currently operating in the Middle East and Africa. The research team of the ERC project LIFE (CoGrant 681673) has been successfully experimenting with the use of low-cost instruments to achieve equally accurate results
Egypt, Greece, and Rome: a History of Space and Places
Full text linkHistorical events literally took place in specific contexts; ‘where things are’
shapes ‘how things are’. In this book, Corinna Rossi examines how three
different ways of interacting with the surrounding world were shaped by
their physical context in ancient Egypt, Greece, and Rome.
Following a discussion on the relationship between history and
geography, Rossi delves into the geographical settings of these three
civilisations, analysing human mobility within them and how cultural
development was shaped by these movements. Rossi also identifies three
possible models to describe the three different approaches specific to each
of these ancient societies.
Egypt, Greece, and Rome: A History of Space and Places is suitable for
students and scholars with previous understanding of these three civilisations
and an interest in the relationship between history and geography
Digital workflow to support archaeological excavation: From the 3D survey to the websharing of data
No full textArchaeology has recently seen a rise in the use of digital tools and new technologies. However, in many cases, innovative tools are used to perform old operations, and their potential is not fully exploited to achieve equally innovative results. Moreover, in the practice of archaeological excavations, the collection of digital data proceeds alongside the collection of classic paper archives, thus prompting the necessity to find a way to combine different sets of data. The research team engaged in the ERC project LIFE (CoGrant 681673) is working on the identification of the most effective survey methods in relation to specific logistic and environmental conditions, as well as on the possibility to efficiently combine digital and paper archives, and is testing the results on two archaeological excavations in Egypt
Pottery from the production site of Muhammad Tulayb, North Kharga
No full textThe North Kharga Oasis Survey (NKOS), co-directed by Salima Ikram and
Corinna Rossi, was initiated in 2001 in order to locate, document, and map archaeological sites in the Kharga Oasis from the northern escarpment to the area just north of Kharga town. Although the oasis contains evidence dating to prehistoric times, the majority of standing remains are from the Late Period onward, with those in north Kharga primarily dating to the Roman era (1st–5th c. AD). Although many of the major sites take the form of fort-like edifices, administrative buildings, domestic spaces, water-distribution complexes, industrial areas, and temples have also been identified. One such site, some 30 km north of Kharga town, is Muhammad Tulayb, where evidence of ceramic production was identified, which is the subject of this paper
3D REALITY-BASED MODELING IN HBIM ENVIRONMENT APPLIED TO ARCHAEOLOGICAL SITES: RECONSTRUCTIVE HYPOTHESIS OF THE LATE-ROMAN FORT OF UMM AL-DABADIB (EGYPT)
No full textThe work aims to deepen the various aspects of three-dimensional modelling based on an image-based survey of an archaeological object. The architecture subject of this study is a
late Roman fortified structure, located in Egypt, in the oasis of Kharga, more precisely in Umm al-Dabadib. The aim was to model in a parametric environment the architectural evidence
measured both with classical approaches and with 3D surveys and to develop reconstructive hypotheses, assisted by historical and architectural documentation of archaeological sites
strictly interconnected to Umm al-Dabadib. If the model usually takes root from a project and develops gradually with it, in the historical and archaeological case the only starting point is
the current state of the building, narrated through surveys and documentation. Thanks to the close-range photogrammetric survey of the entire fort of Umm al-Dabadib, it was possible to
accurately reconstruct its shape and geometry and infer the construction techniques. This made it possible to recognize and understand the richness, peculiarity and uniqueness of each
modelled element, to identify and reconstruct its shape, to draw fairly reliable assumptions about its construction methods and therefore to reconstruct the entire architectural organism.
The irreversible destruction of elements of the building that established its identity is the main reason for recreating it even only in a virtual environment, through a virtual tool, albeit based
on the reality and tangibility of pre-existence. The strength of the reality-based modelling is that from the same digital survey it was possible
to develop different architectural solutions
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
