Varibilità tecnologica o di provienza? Problemi di interpretazione dei dati analitici relativi alla ceramica di impasto e figulina protostorica della Puglia settentrionale (Italia)
No full textLe diversità composizionali nelle ceramiche di impasto e figuline da madonna do Ripalta e Coppa Nevigata osservate mediante analisi archeometriche d'insieme (chimica e minero-petrografica) non sempre sono risulutive per destinguere le diversità tecnologiche tra le classi ceramiche da quelle di area di produzione. In questo studio si presentano i risultati di un test di microanalisi (SEM-EDS) sulla sola matrice argillosa che suggeriscono l'uso di vari tipi di argille per le diverse classi ceramiche
Herodian Machaerus Fortress (Jordan): Investigation of Mortars Belonging to the Hydraulic Constructions
No full textMachaerus Fortress, overlooking on a hilltop the Transjordan side of the Dead Sea, represents an important example of the Herodian defence structures. It was a model of engineering, considering both its military function and the offered quality-of-life. In fact, this site hosted hydraulic constructions with an estimated capacity of the reservoirs of 3000 m(3) (3.000.000 l) per year, allowing people to have supply of potable water and for all the human activities. Given the unquestionable significance of this archaeological site, a comprehensive characterization of the mortars utilized, especially in the hydraulic structures, is here discussed. Therefore, the present work provides hints for new insights on the construction techniques utilized in this area, interesting both from the historical and from the engineering point of view. Moreover, the results here illustrated constitute a valid support in the decision making of compatible materials to be employed in future restoration works

No full textWalking Through Florence to Discover the Stone-Built Cultural Heritage
No full textBathed in the charm of centuries of history and architectural beauty, the city of Florence is a kind of open-air museum which represents the historical memory of the city, from the Middle Age to modernity. The countless masterpieces are mainly made of the rocks outcropping close to the city and surrounding areas. Thus, Florence is characterized by the colours of its stone-built cultural heritage, the warm ochraceous and the cerulean grey of the Pietraforte and Pietra Serena sandstones, but also the white of marbles, the green of serpentinites, and the red of limestones. In addition, other natural lithotypes, together with artificial materials, were used to realise columns, decorations, claddings, masonry finishing, etc. To deepen the knowledge of the stone materials of Florence, the progressive web app “Florence RockinArt” may help us; it is addressed to all those who are interested in discovering the monuments of Florence by carefully observing the stone materials that make up them. The web app contains short historical and architectural notes on the main monuments but, first of all, detailed geological, mineralogical, and petrographic characteristics of the natural and artificial materials of which they are constituted. The best way to visit this charming city is on foot, getting the chance to walk into the history. In this paper, we suggest a selection among the most significant and suggestive walks through the city such as, for instance, looking for the differences between the sandstones Pietra Serena and Pietraforte, the search for churches decorated with the three colours, white, red, and green, or the hunt for little used polychrome materials
Circolazione di ceramica preistorica e protostorica nella Sicilia Nord-orientale e nell'arcipelago eoliano

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
