Gli strumenti per affermare che una superficie è nello stato di “quasi-equilibrio” sono sufficienti?
No full textABSTRACT The variously coloured and plastered surfaces of our historical centres, show, for those who are capable to decode them, a large amount of signs and information. Therefore a question arises: why so often total full re-colouring, or even replastering are observed? Perhaps it is a problem of lack of confidence in the diagnosis, or caution towards the possible evolution of decay? Another observation: it is expected that the current economic situation will determines a limit in the interventions, maybe it's possible that we are forced to intervene again with the well known practice of the "patches", the intervention aimed exclusively to fill the gaps. More and more we have to get used to reconsider the term quasi-equilibrium stated by Mannoni. The article will investigate the reasons for certain behaviours, trying to find solutions to this situation. Through a critical review of some interventions and a discussion of the literature concerning the possibility of detects situations of quasi-equilibrium, we want to propose a method to approach the problem, trying to focus more on prevention and maintenance in order to push more and more towards the conservation of our heritage
The building "stone materials" of the Genoese fortification system from the XIIIth to the XXth century
No full textL'article examine le système de fortifications génoises du point de vue des "matériaux de pierre" utilisés dans leur construction et de leur réponse à l'action des intempèries. Le système de murs et de fortifications couvre une période assez large allant du XIIIème au XXème siècle.Cette étude donne l'occasion de brosser un tableau assez complet de l'évolution des techniques de traitement, de la préparatondes matériaux et de leur mise en place (mortiers à la chaux avec différents additifs et agrégats, différents types de briques, blocs de pierre traités différemment). Ilsera également possible d'obtenir des informations sur la réaction de ces matériaux à l'action des agents de désintégration
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
New scenarios for the Palmaria island (Porto Venere- Ligurian Sea)
No full textThe Palmaria island in the municipality of Porto Venere between the Gulf of La Spezia and the Cinque Terre (Italy) is a complex and integrated system, consisting of several cultural heritage. The way to arrive at a vision of global landscape, understood as the network connection of all the other elements of great historical value begins in 1939 (law no 1497) when the site was declared of great public interest and the landscape has been protected as a single asset with a landscape bond. In 1997, after being recognised as a World Heritage Site, the aims of the active management of this area were: public reuse of the historical and cultural buildings, revaluation of the landscape as an integrated system composed by many singular and peculiar elements and promotion of an alternative cultural tourism compatible with the conservation of the landscape. In 2016 the State Property Agency signed a understanding memorandum with the Ministry of Defence, the Navy, the Liguria Region and the Municipality of Porto Venere for the enhancement of more than 100 public property, including buildings and land, present in the Palmaria Island. How will change the landscape of the island after these agreements between public authorities? The intent of this study is to propose guidelines for an integrated and sustainable management of this unique coastal landscape with the aim of promoting cultural tourism without harming the local population. The landscape is understood as 'a sheet without seams' and becomes the connection of the historical, cultural and natural elements of both land and sea. Within this network some pilot projects are proposed, that contribute to the development of a sustainable tourism model, responding to different needs of different social categories that frequent the area. Among the topics studied: the regeneration of the landscape, the revaluation of the history, traditions and cuisine, the recovery of the relationship with the sea as a landscape value, intelligent reuse of public buildings with existing cultural and historic value
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
