Late Roman villa at Faragola (Foggia, Italy). Laser scanning for a global documentation methodology during field research
No full textLaser scanning is a tool that is increasingly being used in archaeology. While experiments often focus on its use as an instrument for surveying remains of large archaeological sites and ruins, it can also be used in the process of documenting and recording excavations. 3D registering of archaeological stratification is a challenging goal that requires a unique environment for a global set of documentation objects, including old style drawn overlays and plans. What a laser scanner cannot do is survey things that do not exist any more. Our main concern was to merge digital born data from the laser scanner with traditional data that have to be implemented using different technologies and solutions
Il progetto “CARE” nella Puglia centro-settentrionale: primi dati e riflessioni
No full textWithin the European project of elaboration of a corpus of Late Antique and Early Medieval religious architecture (“CARE” = Corpus Architecturae Religiosae Europeae), in central-northern Apulia new archaeological researches (stratigraphic excavations and analysis of masonry) and works of critical review of old excavations conducted in the religious buildings (to some of them specific studies are dedicated in this contribution) have been set up; at the same time, the systematic collection of information derived from the examination of written sources has been also started.
The first results of this integrated analysis of the data were used to propose some lines of reading on the process of affirma- tion of the Christian presence in the territory, on the different promoters of religious building initiatives and on the dynamics of relationships between them, on the roles and the functions that the churches were assuming in the various political-institutional and socio-economic scenarios. A picture emerges, in a first phase, strongly characterized, both in the city and in the countryside, by the bishop action, then, during the Early Middle Ages and especially in the rural areas, reduced (but still archeologically perceptible) from the emergence of new subjects (dukes/Lombard princes, aristocrats) and the progressive consolidation of the monastic presence; religious construction also allows us to follow, starting from the tenth century, the traces of the new equilibrium created in connection with the political-institutional structure established following the Byzantine reconquest and with the transformation of landscapes and socio-economic frameworks
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
Ecologie di Bovisa. Un laboratorio tra società, ricerca e innovazione
No full textL’introduzione di grandi funzioni pubbliche nei processi di rigenerazione urbana, come l’università, è significativa per l’immissione di nuove popolazioni urbane così come di nuove attrezzature collettive ed è qui letta in relazione al fruttuoso innesco di processi di innovazione e interazione tra i contesti locali e la dimensione della ricerca. Questo è ciò che si sta giocando nella periferia nord della città di Milano, dove il Politecnico di Milano, presente con il suo secondo campus dalla fine degli anni ’80, è oggi impegnato nella trasformazione di un’area di cospicue dimensioni, la “Goccia” di Bovisa.
Entro questo quadro, è descritta l’idea di una sperimentazione di forme di interazione stabile tra università e città che, sulla scorta degli esempi già sviluppati dal Politecnico di Milano, propone il modello aperto e articolato di un laboratorio permanente che porta la città dentro al campus, cerca una relazione con le imprese, innesca ed interagisce con diverse forme di rigenerazione, anche temporanee, che coinvolgano il più ampio parterre di soggetti.The input of large public functions in urban regeneration processes, such as the university, is meaningful considering the introduction of new populations and collective pieces of equipment. The contribution reads urban transformations as means to trigger fruitful innovation processes and activate various connections between scientific research and the local contexts. This is what is being played out on the northern outskirts of Milan, where Politecnico di Milano has been with its second campus since the late 1980s and is today engaged in the transformation of the “Goccia” Bovisa urban site.
The idea of experimentation on some stable forms of interaction between the university and the city is presented in such a framework. Based on Politecnico’s already-developed examples, it proposes a permanent laboratory articulated model that brings the town into the campus, seeks a relationship with businesses, triggers and interacts with various forms of regeneration, even temporary, and involves the broadest range of subjects
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
Case report of an endovascular repair of a residual type A dissection using a not CE not FDA-approved Najuta thoracic stent graft system
Full text linkThis report describes an endovascular repair of a residual type A dissection using a medical device that is not marked by european conformity (CE) or Food and Drug Administration (FDA).The patient underwent ascending aortic surgery for acute type A dissection. The 2-year angio-computed tomography demonstrated patency of the residual false lumen with evolution into a 6 cm aneurysm, the extension of the dissection from the aortic arch to the aortic bifurcation with thrombosis of the right common iliac artery. There was no CE- or FDA-marked medical device indicated for this case or any other acceptable therapeutic alternative. We used the Najuta thoracic stent graft and successfully handled the pathology in a multiple-phase treatment.Technology is evolving with specific grafts for the ascending and fenestrated grafts for the aortic arch. In this single case the Najuta endograft, in spite of the periprocedural problems, was a valid therapeutic option
