The new trend of 3D archaeology is ... going 2D!
No full textNowadays we cannot imagine any archaeological activity – fieldwork, lab work or historical analysis and synthesis – without the support of information technologies. 3D is an important part of this scenario, considering that archaeology is a reality composed of 3D entities that have to be analysed, understood and reconstructed. It comes as no surprise, therefore, that the 3D reconstruction of monuments and sites is one of the most important applications of IT to archaeology, given its ability to recreate, in a perfect and realistic form, something that no longer exists with a strong visual impact. But what if we move our aim from visua- lisation techniques to content? If we focus on communication aspects, we need to consider the fact that 3D may not always be the right solution: if our goal is to make the real meaning of archaeology fully understandable to a wider audience we need something more: we need a story
A dig in archive. The case of Herdonia
No full textSince 2004 the Department of Humanities at the University of Foggia has held the historical archive of Herdonia, contai- ning the documentation of archaeological research carried out in the Roman town of Northern Apulia from 1963 to 2000.
The story hidden in the archive is long and complex, written in the documentation produced during 40 years of excavation and survey that led to the discovery of one of the largest Daunian, Roman and medieval sites in southern Italy. The archive is a unique memory covering a long time-span, containing documents that are parts of the history of archaeological research, linked with various methodologies (from long trenches and Wheeler methodology to big areas) and realized using different techniques and technologies (from paper drawings to CAD models, to 3D scans).
The purpose of activities carried out at the Digital Archaeology Lab is to share all the documents of the Herdonia archive starting from spatial data, carrying out specific workflows for building a common environment in which the digitized legacy data and digital born data can stay together.
The first phase of the project has been thus the recovering all the hand-drawn maps, their digitizing and georeferencing in an open source GIS. For the first time all of the sectors and trenches dug up on the site of Herdonia stay together, georeferenced, under the same roof
Work ability index in a cohort of railway construction workers
No full textWorking conditions and work load can have a significant effect on work ability, due not only to their direct impact on health and well-being, but also to the possibility they let to maintain job and competence at acceptable levels with normal ageing. In this perspective a cohort of 377 manual workers, aged between 21 and 67 years, engaged in a railway tunnel digging have been examined. They were miners, carpenters, maintenance workers, dumper drivers and clerks/storekeepers. In the whole cohort, the Work Ability Index resulted excellent in 23.6%, good in 47.2%, moderate in 24.4%, and poor in 4.8% of the workers (12.2% in those over 55 years). The mean WAI progressively decreases from the youngest to the oldest decade (from 41.5 in subjects under 25 years to 36.0 in subjects over 55 years), and passing from day-work (39.7) to semi-continuous three-shift work (39.2) and continuous 3-shift work (37.7). Miners and carpenters showed the highest percentages of poor-moderate WAI (31.6% and 35.1% respectively); these latter show also a steeper decrement over the years. Compared to other working groups of industrial and service sectors, the railway construction workers show the lower mean WAI scores at all age groups and the most pronounced decrease over decades
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
Hand-free Interaction in the Virtual Simulation of the agora of Segesta
No full textThe aim of the paper is to illustrate an application of immersive virtual reality, concerning the archaeological investigation in the
agora of Segesta. The research, led by a team of archaeologists and researchers of the Scuola Normale Superiore and the University of Pisa, has developed a 3D simulation of the ancient agora, allowing experts and non-experts to virtually reproduce
the excavation activity and to interact with the hypothetical reconstruction of the monuments. The application is configured to run in two different virtual environments: within the CAVE-like system of the DreamsLab at the Scuola Normale Superiore, where the user can manage it in a complete hand-free way, and on wearable, such as the Oculus Rift DK2 and the Myo Armband, making the application easily portable and available on the field, during the fieldwork activity, the final goal being to bridge the gap between the data acquisition and interpretation steps
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
