Detailed 3d reconstruction of the great inscription of Gortyna, Crete: acquisition, registration and visualization of multi-resolution data.
No full textIn this paper, we present a national R&D project, DIGITAL OCEAN1, which is a system allowing the distribution of submarine
multimedia content resulting from the integration of three modules: an underwater device for multimedia content display, a software
for virtual environments edition and a demonstration video game. These three modules constitute the project's main components. In
fact, four partners are involved in the development of the project, each handling specific aspects of it: RATC team of IBISC2 works
on Oce@nyd for the digital media collection on the internet, which is a groupware architectural model based on Web services and
software agent’s integration, bringing a new approach for creating collaborative applications and innovation to the CSCW domain.
The I&M team of LSIS3 takes part in the design of the Oceanyd software that allows a real-time sea-beds visualization along with a
data editor interface. Using a popular open-source graphics engine, an underwater virtual environment is created and composed of
several fauna and flora specimens, and rendered with effects such as water plane reflection, skybox, lights, etc. Another partner,
SEMANTIC-TS4, provides the Digital Elevation Model (DEM) for creating virtual sea-beds, along with measurements concerning
underwater acoustics, oceanography measurement data and signal processing. Finally, VirtualDive5, the company that has created the
project and handles its overall management and marketing. This project constitutes the company's unique activity, so its commitment
to the project’s success is total. The company has a global vision of the project, where it should be directed at short and long term
but also a comprehensive view of all project details and of their evolution in time

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
Shepherds and miners through time in the Veneto Highlands: Ethnoarchaeology and archaeology
No full textThe eastern Italian Pre-Alps in the area between Lake Garda and the river Brenta have been exploited from historical times to the present day for many purposes that are typical of a mountain zone. Among the most important activities were mining and stock-raising. Ethnoarchaeological and archaeological projects have been carried out in the study area in order to detect and document the traces of human activities, especially shepherds and sheep farming. To date, it has been possible to locate hundreds of sheep folds, shepherds’ shelters and breeders’ houses in the uplands, to discover that the most ancient traces of organised human exploitation in the uplands go back to the Bronze Age, while during the Iron Age a change in upland economy is evident, possibly connected with the organisation of larger territorial polities and their boundaries
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
