Tendenze contemporanee per il progetto della ricostruzione nei siti Patrimonio dell'Umanità UNESCO
Disastri naturali e conflitti su vasta scala non solo mostrano la fragilità del patrimonio in generale, ma anche di quella categoria speciale di luoghi riconosciuti come Patrimonio Mondiale dell’Umanità Le distruzioni che hanno colpito siti Unesco in Iraq, Siria, Yemen ecc. hanno, negli ultimi anni, rinnovato l’interesse e riacceso il dibattito sulla pratica forse più controversa per chi si occupa di progetto del patrimonio, e cioè la ricostruzione.
E i siti Unesco, proprio per la dimensione laboratoriale che li connota rispetto ad approcci, metodi e pratiche innovative di conservazione, costituiscono una casistica interessante per il tema ricostruttivo, testimoniando come attraverso la riflessione sui casi specifici ed il dibattito interdisciplinare tra l’organizzazione internazionale, i suoi organi consultivi e coloro che si occupano di patrimonio, lentamente stia mutando l’approccio nei confronti del progetto della ricostruzione, dall’emanazione della Carta di Venezia sul Restauro (1964), che ne ha di fatto depotenziato le possibilità esprimibili in contesti patrimoniali, sino al momento attuale in cui la scala ed il portato degli eventi distruttivi, insieme alla ridefinizione del concetto di patrimonio, richiedono un rinnovamento di approccio nei confronti della ricostruzione, anche attraverso una ridefinizione dei concetti di autenticità e di integrità oltre che, nel caso dei siti Unesco, degli Outstanding Universal Values per il sito ricostruito o da ricostruire
A Techno-Economic Modelling and Component Sizing in Renewable Energy Communities: The Perspective of Technical Facilitators
Toxicological profile of plasmonic nanoparticles in zebrafish model
Plasmonic nanoparticles are increasingly employed in several fields, thanks to their unique, promising properties. In particular, these particles exhibit a surface plasmon resonance combined with outstanding absorption and scattering properties. They are also easy to synthesize and functionalize, making them ideal for nanotechnology applications. However, the physicochemical properties of these nanoparticles can make them potentially toxic, even if their bulk metallic forms are almost inert. In this review, we aim to provide a more comprehensive understanding of the potential adverse effects of plasmonic nanoparticles in zebrafish (Danio rerio) during both development and adulthood, focusing our attention on the most common materials used, i.e., gold and silver
Per un'idea di città archeologica
Il contributo descrive il progetto per l’agorà ellenistica di Kos, di Carlo Moccia, che, pur nella sua condizione parziale rispetto alla totalità del monumento antico e della forma urbana, aspira a definire dei principi capaci di informare una più generale idea di ‘città archeologica’
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
