Archaeological Impact Assessment: The BREBEMI Project (Italy)
No full textThe work presented in this contribution forms part of the BREBEMI project, in reaction to a major motorway construction development linking the towns of Brescia, Bergamo and Milan in northern Italy for a total length of about 120 km. For the first time in Italy a set of non-invasive procedures is being used systematically in order to reduce archaeological risk in advance of motorway construction. This innovative project relies on the methodical collection of information from historical and geographical documentary sources, along with geomorphological analysis, the examination of existing vertical air photography, the collection of new data through targeted aerial survey and oblique air photography, the acquisition of LiDAR data along the whole of the motorway route (160 kmq at a resolution of 4 dots per sqm) and the systematic collection for very substantial areas of geophysical data, both magnetic (AMP) and geoelectrical (ARP) – a total, so far, of 438 hectares of AMP and ARP data (mesh 0,5x0.5 m and 0.5x0.08 m). Test excavations are planned systematically to verify anomalies and the Superintendency for the Region of Lombardy is also initiating random trenching for a total of 5% of the surveyed area. A GIS platform for the project has been designed to manage and integrate all of the data at every stage of development (from data acquisition in the field to interpretation and field checking) as well as to demonstrate overall patterns and to create predictive models. The objectives of the project are to reduce as far possible uncertainty about the presence of archaeological remains along the route and in particular to identify areas which should be protected from destruction because of the presence of either upstanding or buried archaeological remains. As a result of our project be believe that the greatest improvement in rescue and preventive archaeology will surely come not from technological development alone but from a more consistent application of the kind of ‘total archaeology’ and ‘global’ historical approach. Only then will it be possible to reduce the archaeological risk and maximize the archaeological returns from preventive and rescue archaeology
Electrical surveys
No full textDuring the International Summer School students and lectures - after three days theoretical lessons - spend four days into the field collecting geophysical measurement. The archaeological test-site is placed on lowland quite close to Grosseto, the city where the University of Siena recently open a satellite of the Department of Archaeology and History of Arts and where there was the headquarter of the Summer School. The site is a further big roman villa starting form the first century AD that we estimated occupied until the sixth century AD. Grid collection and pottery analysis allow us to recognize the re-occupation of the site during the late ninth and tenth century AD. The site measure about 4 hectares in extent so we decide to focus our attention on four square sample of 50 by 50 meters where we rotated four different geophysical methods: magnetometry (fluxgate, Overhouser, Cesium), ground penetration radar (GPR), electro-magnetometry (EM), electrical resistivity tomography (ERT).
In this section we repot the work achieved during the Summer School but also we publish the data collected starting from the 2001 when the site has been discovered during the Aerial Archaeology Research School (Culture 2000 project) to the last survey we did in autumn 2007. One intention working on the Aiali test-site is to apply the highest available level and intensity of archaeological prospection methods on a large, complex and stratified site, producing material from the from Etruscan, Roman and Medieval periods. As our good friend Chris Musson has argued – during one of our long discussions on this topic – the archaeological objective and outcome of the Aiali project has to take account of the critical impact of the kinds of information that are available for recording: to use his own words “in assessing the potential or interpretation of a landscape it is at least as important to know what may not be visible as to appreciate what is visible”.
The first and in the second chapters of section 2 Stefano Campana introduces the site background and the results obtained through remote sensing tools from Quickbird-2 satellite imagery, to vertical air photographs and aerial survey. In chapter 3 Emanuele Vaccaro and Mariaelena Ghisleni provide the results of field walking survey, grid collection and the detailed study of pottery. Chapter 4 is addressed by Stefano Campana and Salvatore Piro to introduce the geophysical surveys of the site. In the next chapter Helmut Becker, Stefano Campana, Thomas Himmler and Iacopo Nicolosi to discuss the results in the sample areas of different magnetic sensors (Fluxgate, Overhouser And Caesium-Magnetometry). Chapter 6 handles with Ground Penetrating Radar (GPR) surveys by Dean Goodman and Salvatore Piro. Chapter 7 discuss the results obtained through the application of electromagnetic survey by Alain Tabbagh while the next one deals with the last methods applied during field work, electrical survey and is summarized by Michel Dabas and Gianfranco Morelli.
As conclusion Stefano Campana and Salvatore Piro, an archaeologist and a geophysicist, try to combine all the information together. Through a GIS-based analysis the editors integrate different sources geophysical measurement as well satellite imagery, aerial photograph, archaeological information collected during field walking survey and archaeological knowledge. The critical impact of the work is addressed to show the improvement of available archaeological information as a consequence of the improvement of the survey methods

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
