Evoluzione di un paesaggio alpino alle sorgenti del Brembo (Carona, BG)
No full textIl volume raccoglie una serie di contributi presentati nell’ambito del corso di alta formazione “Montagne e Archeologie”, organizzato come attività congiunta dei Corsi di Dottorato “Culture d’Europa”. Ambiente, spazi, storie arti, idee” (Università di Trento) e “Scienze archeologiche, storico-artistiche e storiche” (Università di Verona), a cura di Diego E. Angelucci, Enrico Croce, Mara Migliavacca e Fabio Saggioro. I casi-studio ricadono nell’ambito della cosiddetta “archeologia di montagna” e offrono esempi del lavoro archeologico alle alte quote o nelle aree vallive, significativi per suscitare sia la discussione metodologica sia la riflessione sulla presenza umana negli ecosistemi montani.he paper gives some insights of the data collected in the area of Carona (province of Bergamo, Italy) within the framework of the author’s PhD
thesis. The main objective of the project is to understand the diachronic evolution of a mountain landscape shaped by human-environment interaction. The
area was exploited for mining and pastoral activities from early medieval times; we also know that some kind of human occupation occurred in the area during
the late Iron Age and the early Roman Age. The data collected through field survey, cartography, and archive study have been implemented through GIS and
statistical analysis. The main type of evidence detected are the mountain huts (baite), along with pastoral structures, charcoal production sites and mining
assemblages. The analysis of structural decay and cartographic presence of baite lead to the definition of a built landscape chronology. The main outcome is
the reconstruction, at different levels of accuracy, of the landscape evolution from Iron Age to the present time. The proposed methodology, as a synthesis of
different research experiences in the mountain environment, could lay the foundations for a broader reflection on possible shared and common approaches to
“mountain archaeology” as an autonomous archaeological field of research

Colecistectomia laparoscopica clipless con dissettore ad ultrasuoni versus colecistectomia laparoscopica tradizionale in regime di day surgery. Studio prospettico randomizzato
Full text linkIl nostro studio nasce, dall’esigenza di valutare l’effettiva possibilità di utilizzare il dissettore ad ultrasuoni per eseguire la colecistectomia laparoscopica in day surgery sia come strumento di dissezione e coagulo che per sigillare il dotto cistico e l’arteria cistica. La colecistectomia laparoscopica clipless con dissettore ad ultrasuoni si è dimostrata una procedura efficace e sicura anche in regime di day surgery. L’utilizzo routinario del bisturi armonico non incide sui costi generali della procedura ed anzi consente un ipotetico risparmio rispetto alla colecistectomia laparoscopica tradizional
Looking for BVER into the GRASS. Database pubblici e modelli predittivi in archeologia: il progetto BVER in dialogo con GNA
No full textThe work presented in this paper investigates the settlement dynamics of the Lower Verbano area between the Iron Age and the Middle Ages. The known archaeological sites, sourced from the public GNA database, were used along with a series of physical characteristics of the territory as variables for the calculation of an inductive predictive model. The results demonstrate the analytical potential of this methodology in the field of archaeological landscape analysis, while also highlighting its shortcomings in strictly predictive terms. The model created for the general record of archaeological sites in the GNA proves to be underperforming from a predictive standpoint, whereas heterogeneous results were obtained when the sample of sites was sectioned chronologically. The model calculated for the Iron Age shows a high discriminatory power and, when compared to the models for the subsequent periods, underscores the importance of the selection of variables for this methodological approach. The use of data from a public database revealed several deficiencies in the management of complex territorial information inherent in its structure, but also highlighted the intrinsic potential of such a tool, which we hope to develop more fully in the future
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
