Web-gis storico-archeologico della Val di Vara
Full text linkThe “Tra Monti” project concerns a set of Municipalities in “Val di Vara” (La Spezia, IT). The goal
is to collect archeological and architectural data about the area of study, as well as to build a sort of
“oral memory” in order to promote the cultural heritage of the area and for scientific purposes. The
director of the project is the University of Pisa which has promoted a collaboration between
historical, archeological and IT experts. A devasting flood just during the activity, which destroyed
cultural goods documented some days before, stressed the goal of the project.
We designed and build a web site to manage and publish the information we collected. The web site
uses only OS and Free SW components; some web 2.0 functions are available and an important GIS
part is present.
The spirit of the project is sympathetic to the actual technological context, whose opportunities
suggest to consider the territory as a mix of “objects” and “people”. Both experts in the universities
and local people on the territory can give a contribution in enriching the DataBase with new data
and a knowledge contribution with their different particular skills
Database, WebGIS, storia ed archeologia: riflessioni metodologiche dietro un progetto sulla Lunigiana medievale
Full text linkThe paper presents the work of a research team composed by scholars, researchers and graduates of the University of Pisa and CNR. The team aims to create a WebGIS of the Low Lunigiana (Tuscany) in the Middle Ages that could be useful for different users: local administrators, tourists, inhabitants and researchers.

Artificial Intelligence Techniques in an environmental Geo DSS
No full textThe idea of the integration between GIS and Artificial Intelligence, two complimentary technologies, was proposed some years ago. This integration is promising since GIS is very efficient in heterogeneous data integration and geographical analysis, whereas AI, and expert systems in particular, are suitable for handling imperfect knowledge and non structured problems. Environmental problems are a good test bed. We describe the design an implementation of an Environmental Decision Support System to control the quality of water in the Arno river (Tuscany). The system integrates a knowledge base and an inference engine, a model base, a GIS (geo data and processing facility) and a User Interface. The system provides domain experts with information to evaluate the effectiveness and socio-environmental impact of one or more remedies against an abnormal environmental condition. It may be used in emergency conditions or as part of a long term strategy to enhance the quality of river water

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
