St. Euphemia’s cave inscriptions: ancient navigation, beliefs and devotion (Vieste, Italy)
No full textThe paper will refer to the ‘sacred’ dimension of navigation, which has developed over the centuries and in which it is difficult to
distinguish the clear separation between religion, superstition, and beliefs, also testified by the number of cults and deities linked
to travelling by sea, from Poseidon to Aphrodite, to the Dioscuri, later replaced by Christ, Mary and Christian saints. The paper
will mention this aspect of the navigation, focusing on the lower Adriatic coastal landscape marked by the presence of landings
connected to places of worship, sometimes true ‘coastal maritime sanctuaries’. Reference will be made to the coastal shrines that
mark the Apulian and Albanian shores, in particular to the Venere Sosandra cave at Vieste (Apulia), where a wide archaeological
project is underway, carried out by the Universities of Bari and Foggia
Culverted watercourses as an anthropogenic constraint of flood risk in the historical centre of Genoa (Italy)
No full textIn recent years, artificial cavities have raised interest among the scientific community, both due to their relevance in terms of cultural and landscape heritage and because they are linked to potential hazards to surface structures. Underground voids in cities have
been often established over time with a specific purpose or have resulted from the layering of different urban evolution phases, which in Mediterranean cities are often thousand years old, the case of culverts being particularly frequent. Generally, culverts
have been associated with the need to expand urban areas due to space constraints. Underground voids have been established and modified (or even under-dimensioned) over time and their state of efficiency and preservation is hardly verified, leading to
very hazardous conditions. This research presents the waterways in the historical centre of Genoa, the coverage of which, now almost complete, began in the Middle Ages. While the historical channelization of the streams of the old city can be considered as a structure of cultural value, it should be pointed out that the subsequent modifications and state of preservation of such artifacts have led to localized hazardous conditions and thus risk to buildings and infrastructure, some of which have been recognized as
UNESCO World Heritage Sites (“Strade Nuove and Palazzi dei Rolli”). Therefore, there is need to acquire detailed surveys of the entire channelized and culverted hydrographical network in order to assess its hydraulic efficiency, hydrogeomorphic features, and
structural suitability, and to activate a monitoring network. Such measurements are crucial for effective management of hydrogeomorphic risk in urban areas, also in light of Global Climate Change
Artificial cavities and geo-risk assessment: the case of "The Strade Nuove and the system of the Palazzi dei Rolli" Unesco World Heritage site in Genoa (Italy)
No full textArtificial cavities are increasingly studied by the scientific community and several researches were carried out in recent years concerning their importance as elements of cultural heritage but also associated geo-risks. This is a highly interdisciplinary line of
research, requiring not only the combination of science and social science approaches, but also technical knowledge for surveying activities in the underground environment, made easier in recent years by technological development. The research becomes
even more complex and articulated in urban areas, not only due to a greater concentration of artificial cavities, but also for the complex historical evolution of buildings and the stratification of urban phases. This research introduces a first census of artificial cavities in the historical centre of Genoa, with particular reference to the area recognised as a UNESCO World Heritage Site since 2006. A preliminary database containing more than 150 artificial cavities referable to hydraulic underground works was developed, which includes hypogean civilian dwellings, religious work, military and war works, mines and transit. The overlay of underground development of man-made cavities and the built environment on the surface using GIS has highlighted numerous buildings of great historical-monumental value and connecting streets built on underground voids. This opens up many research perspectives, and it highlights the priority to complete the census and detailed survey of all artificial cavities in Genoa historical centre: in light of the effects of climate change, correct management of cultural heritage and landscape is crucia
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
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
