Aménagement des zones humides et hagiographie
No full textil contributo si colloca all'interno di una linea di ricerca portata avanti dallo scrivente e diretta a evidenziere l'importanza che le fonti agiogrsafiche hanno all'interno della ricostruzione delle variazioni ambientali tardo-antiche e alto-medievali. Nel caso specifico vengono lette in chiave paleoambientale e paleoidrografico le vicende legate alla vita di alcuni santi. ovviamente, per poter raggiungere questo obiettivo, è necessario cje il territorio in cui questi personagggi sono vissuti ed hanno operato sia analizzato da un punto di vista storico-topografico e geomorfologico
Relations between ancient settlement and the physical environment: a case study of the area from Dora Baltea river to Scrivia river (Western Po Plain - Italy)
No full textAs is known, since the prehistory, the interrelationship of the man with the landscape have become increasingly close. The study carried out on the western Po plain between the confluence of the Baltea and Scrivia Rivers, fully confirms this assumption. The study area is characterized by a typically fluvial morphology with Holocene terraces enclosed within the carved late Pleistocene plain (Main Level of Plain) and sometimes in direct contact with the Monferrato hills. The reconstruction of the evolution of the bed of the Po River has highlighted as, in certain reaches, it has been the prevalent tendency to digression and therefore instability, while in other reaches the bed was maintained more stable and less wide. Over the past two centuries, human activities especially of rice cultivation, largely cleared the remains of ancient morphologies and settlements. However it is possible to recognize a link between the distribution of population and landscape. In fact, the settlements, including the Bronze Age of Pobietto, lie mainly on higher terraces. In Roman and Medieval age, the Po river becomes very important related to its wideness or stability: the major road axis crossing the Po were located where the river is more narrow and more stable. For example in these areas, are located the cities of Valenza and Casale Monferrato, which correspond to the Roman Vardacate and Valentia. A similar location have many medieval “villenove” and the Breme and Aqualonga early medieval abbeys, which are, with Lucedio and San Genuario, the center of the re-colonization after the late-antiquity crisis. Therefore, it should be noted how are important the integrated contributions of the geomorphological and historical and archaeological study for understanding the evolution of an area
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
Il cosiddetto Traiano di Ostra
No full textStudio di una statua di età romana scoperta nel 1841 presso Ostra Vetere nelle Marche. Inizialmente ritenuta un ritratto dell'imperatore Traiano, la scultura rappresenta più verosimilmente un personaggio ignoto, ma comunque attribuibile allo stesso periodo
Un capitello tardoantico frammentario dallo scavo di Ostra

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
Entre terre et eau : histoire de fragiles équilibres dans la plane de Sibari
No full textil contributo presenta i risultati di uno studio interdisciplinare sulla piana di foce del Crati. qui l'analisi geomorfologica e storico topografica ha consentito di evidenziare il reciproco condizionamento che si è avuto nel tempo tra la geografia ffisica e la presenza antropica, mettendo in evidenza come il diverso controllo dell'uomo sul crati abbia portato a notevoli variazioni fisiografiche relative sia all'assetto della piana che alla linea di costa
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
