Integrated digital survey methodologies for the knowledge and enhancement of the ancient city walls. The “Curtain” of Santa Chiara in Cagliari (Italy)
No full textThe contribution shows some results of a multidisciplinary research in which architectural surveying and representation methods are supported by archival documents analysis. The procedure is applied in a limited area of the ancient walls of Cagliari (Sardinia, Italy). The sector consists in the meet point between the sixteenth century bastion called “Curtain” of Santa Chiara realized in the period 1575-1578 by the military engineer Giorgio Paleari and the curtain of de Cardona commissioned by the Viceroy in the 30s of the same century. The historical documents indicates the presence of medieval structures, vaulted chamber and passages designed and built during this period. This source, supported by the knowledge of construction techniques indicated in the military treaties, allows a first graphic representation of the sixteenth century bastion, of which today we can only recognize a part of the vaulted gun chamber positioned along the curtain of de Cardona
Rappresentare l’architettura militare tra ‘antichi’ linguaggi e nuove frontiere. Le mura di Cagliari in Età Moderna
No full textLa cinta muraria di Cagliari costituisce un importante esempio di architettura militare, tutelata per il suo valore storico-ambientale e paesaggistico, della quale conserva la forma impostata dagli Spagnoli nella metà del Cinquecento e le opere volute dai Piemontesi nel corso del Settecento. In particolare la sequenza di opere “alla moderna”, che dal bastione Santa Croce si susseguono lungo l’asse nord-sud in direzione del bastione Balice, e gli ampliamenti situati nel settore nord e nel settore orientale costituiscono il risultato di una serie di trasformazioni che hanno ridisegnato e ampliato la linea difensiva sostenendo logiche insediative, religiose e militari.
L'attuale conformazione di sito pluristratificato custodisce le testimonianze dei diversi passaggi che hanno " ridisegnato e scolpito" le forme dei luoghi e creato un paesaggio che connota fortemente il quartiere Castello e la città stessa.
Una tutela consapevole di un patrimonio storico caratterizzato da valori e criticità richiede una conoscenza approfondita delle trasformazioni avvenute e un'analisi delle dinamiche in atto, affidata ad indagini multidisciplinari. Lo studio dei diversi aspetti utili a garantire una consapevole gestione del patrimonio storico è tuttavia nelle mani degli specialisti, padroni di un linguaggio -a volte di difficile comprensione per i profani- che necessita di mezzi di rappresentazione appropriati al fine di favorire una più ampia diffusione e una maggiore consapevolezza dei valori.
Una rappresentazione che fino all'Ottocento è stata principalmente finalizzata alla descrizione del progetto architettonico oltre che alla documentazione dei luoghi, come nei taccuini dei viaggiatori.
Tuttavia, la complessità della stratificazione storica della città contemporanea richiede l'utilizzo di un linguaggio strettamente tecnico e di un'illustrazione scientifica che a volte sacrifica gli aspetti legati alla divulgazione.
Il passaggio dal modello puramente tecnico a un modello di facile lettura diviene uno degli obiettivi di una più ampia ricerca -presentare e illustrare le trasformazioni urbane- che trova nella piazzaforte di Cagliari un'opportunità per esplorare le diverse modalità di analisi grafica e di linguaggi affidati a strumenti tradizionali e digitali, anche integrati.The city walls of Cagliari are an important example of military architecture protected for its historical-environmental and landscape value.
The actual conformation of a multi-layered site preserves the signs of the different changes that have "redefined and sculpted" the shapes of the places creating a landscape that strongly characterize the Castello district and the city itself.
The sequence of bastions located in the north and in the western sector of Castello, in particular, is the result of a series of urban transformations that have redesigned and expanded the defensive line by supporting settlement, religious and military reasons.
A conscious protection of a landscape characterized by values and criticalities requires an in-depth knowledge of the transformations happened and an analysis of the dynamics in progress, entrusted to multidisciplinary investigations. However, the knowledge of the many aspects useful to guarantee a mindful management of the historical heritage is in the hands of specialists, masters of a language -sometimes difficult to understand for the layman- that needs appropriate means of representation to support a wider dissemination aimed to a bigger awareness of values.
A representation that until the nineteenth century was mainly aimed to describe the architectural project as well as the documentation of the places in travelers' notebooks.
However, the complexity of the historical stratification of the contemporary city requires the use of a strictly technical language and a scientific illustration that sometimes sacrifices the aspects related to disclosure.
The transition from the pure technical model to a model easy to read is one of the objectives of a broader research -representing and illustrating urban transformations- which finds in the stronghold of Cagliari an opportunity to explore the different ways of graphic analysis and languages entrusted to traditional and IT tools, including integrated ones

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
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
