No full textUnderstanding and recovering identity. A comparison between Castelvecchio Calvisio and the refoundation of Marsica
No full textThis article focuses on the readability, understanding and conservation of the town’s identity, resulting from the coherence of the typological and figurative character of its architecture and minor buildings and its morphology, and compares the reality of Castelvecchio Calvisio with that of some of the towns of the Marsica area, damaged by earthquake in 1915. Amongst these latter, the small city of Avezzano also lies in the Province of L’Aquila: over the course of several decades it was transformed from a walled town surrounded by countryside and lake into a ‘provisional city’: a transformation due firstly to a decided mutation in the economy of the area and then to its destruction by an earthquake and subsequent reconstruction
Filling the gaps? The problem of integrating the missing elements in historic centres damaged by eartquakes
No full textSome of the earthquakes that blessed Italian territory in the last 40 years (starting from Friuli earthquake in 1976) created strong damages in many small towns and little centers, where the historic network of buildings and roads was often suddenly interrupted or even cancelled. Besides the immediate huge sufferance of many human lives lost, there is also a long-term effect of the seismic destruction: the disappearing of the reference framework of a small community, often accompanied by the displacement of the population from the damaged old center during the emergency phase, followed by the final abandonment of the site and the unavoidable destruction.
In the analysis of seismic damages on historic buildings, many attention was paid in the past to the behavior of the single building, trying to understand the reasons of the peculiar weaknesses that each building exhibited face to seismic actions: this kind of observations give rise to a better knowledge of the seismic behavior of ancient constructions and also to a more appropriate approach to their reinforcement, both after the earthquake (and subsequent damage) and before that a new one can occur.
But only in recent years attention has been paid on buildings that are closely connected together, although often built in different times, and that sometimes strongly rely structurally on the already existing ones, almost for the resistance to the horizontal loads: this is the common way of building in historic centers, where houses are built in rows, or in blocks; and also the rows are connected together, like in Castelvecchio, with some kind of vaults or arches crossing the old paths. Besides the local weakness of the single building, an overall vulnerability of the system of buildings is to be studied, giving rise to the collapse of some parts of the aggregate or concentrating the damage in some of the core resisting elements.
So, despite the difficulty, an interpretation of the response of such systems can be made only taking into account the interaction between the different buildings and their constructive relationships, so that an history of the construction and of the damages occurred and repair provided is to be followed, also before any reasonable structural analysis, based mainly on direct observations of the buildings. Moreover, any proposal of integration of the loosing part of the urban network must take into account the seismic response of the aggregate, and how (or if) the new element is able to interact with the old parts also from the structural point of view; so that the question arise of when is useful (or mandatory) to rebuild collapsed buildings, and when instead the new gaps or the resulting new spaces may offer new possibilities for urban living, and must be regarded as a result of a natural evolution process
I cammini d'Italia: Italy's routes. Local Enhancement Strategies
No full text«As 2016 was the national year of walking routes, 2017 the national year of villages and 2018 the year of Italian food, 2019 will be the year of slow tourism». So said the Italian Minister for Cultural Heritage and Activities and Tourism at the end of 2017 during a presentation of the Digital Atlas of Walking Routes, the Ministry’s new portal for tourists who want to travel across Italy at a slow pace. The launch of the Cammini d’Italia network is certainly an effort to re-balance the local tourist pressure, characterised by unsustainable peaks in the most extreme and known cases, where public administrations have been incapable to find any alternative solutions to reduce the number intensity of accesses (Venice, Florence among the cities of art, Limone del Garda, the Cinque Terre National Park, to mention the most famous and controversial destinations). The launch of the Cammini d’Italia network is also a way to develop the productivity of some parts of our cultural heritage, and the surrounding settlements, which are unaffected by tourist pressure, underused, marginalised, perhaps even depressed, but still capable of triggering synergistic and regenerative processes. But, more generally, the launch of Cammini d’Italia, seen as a local tourist promotion strategy, embodies «the art of adding value» (Carandini, 2017: 144), as a necessary action to safeguard, protect, maintain and manage the cultural heritage that abounds in this Country
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
A View from Above. Geodesy and Satellite Image Analysis in the Islahiye Valley
No full textThe paper presents some of the surveying experiences, mainly at territorial
scale, performed by the authors at the site of Tilmen Höyük, in collaboration with
archaeologists and researchers from other fields. Satellite imagery, multi-scale digital
Photogrammetry and Space Geodesy, integrated together, allowed a modern approach
to the representation of the archaeological area and the surrounding territory and to
record, manage and share all the acquired data in a single well-established reference
system. All this information represents a shared dataset useful in a multi-disciplinary
perspective for different applications and communities
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
