No full textDisaster Risk Management of Cultural Heritage Sites in Albania.
Full text linkUNESCO has a vital role to play in constructing a global culture of disaster preparedness and mitigation, building in the minds of people a Disaster Risk Management of Cultural Heritage Sites in Albania culture of resilience to risk, promoting awareness, education and capacity and foremost a different way to approach the domain of Disaster Risk Reduction (DRR) and preparedness. UNESCO is also the secretariat of the 1972 World Heritage Convention, of which the properties have recently been the focus of substantial advancement in securing better capacity in risk management and reduction.
Since UNESCO is engaged in important actions for the protection of cultural heritage it implements several projects in post disaster scenarios. This book has been elaborated as a final outcome of the project “Natural Risk Preparedness and Mitigation - Building capacity in the field of risk mitigation for Cultural Heritage properties in Albania” during the period 2011-2013.
The project aimed to streamline disaster risk management in the Country, using its World Heritage properties as demonstration sites. The project was conceived to assist the country in order to enhance its capacity for Disasters Risk Management (DRM) and advancement in seismological and geological
vulnerability of Cultural Heritage properties
The geological model of Celano town area for seismic microzonation activities
No full textIn this paper are presented the results of integrated investigations aimed at building a reference geological model for the seismic microzonation of Celano municipality (Central Italy). The study area is located along the northern rim of the Fucino basin, which is an intermontane half-graben filled by thick Plio-Quaternary alluvial and lacustrine deposits and is surrounded by Meso-Cenozoic limestone and Neogene sandstone relieves, with mean elevation around 1500m a.s.l., that also represent the bedrock units of the basin itself. Evidences of recent tectonic activity within the Fucino basin have been pointed out by several paleoseismological studies recently performed to better frame the effects of the seismogenic structures responsible for the Ms 7.0, 1915 Avezzano earthquake and other historical and prehistoric seismic events occurred in the area. On the basis of integrated site and laboratory investigations, such as surface geological surveys, borehole logging, isotope geochemical analyses based on Th-230/U-234 dating method, geotechnical investigation and hydrogeological prospecting, the geological model of the area was built. The identification of such model was fundamental in view of correct planning and development of further investigations and analyses, mainly based on geophysical methods and seismic response modelling, carried out by other research teams cooperating within the Celano seismic microzonation project.

Influence of structural framework on mountain slope deformation in the Maiella anticline (Central Apennines, Italy)
No full textRelationships between tectonic framework and gravity-driven phenomena have been investigated in an area of the Central Apennines (Italy) characterised by high relief. The north-south, half-dome shaped Maiella anticline lies in the easternmost part of the Apennine fold-and-thrust belt. Its backlimb is bordered by the Caramanico Fault, a normal fault with a maximum downthrown of about 3.5 km that separates the western slope of the Maiella Massif from the Caramanico Valley. The southwestern Maiella area is affected by deep-seated gravitational slope deformation indicated by major double crest lines, down-hill and up-hill facing scarps, a pattern of crossing trenches, bulging at the base of slopes and the presence of different types of landslide and talus slope deposits.The onset and development of deep-seated gravitational slope deformations and the location of Quaternary, massive rockslope failures have been strongly influenced by the structural framework and tectonic pattern of the anticline. Deep-seated gravitational slope deformation at Mt. Macellaro-Mt. Amaro ridge has developed along the Maiella western, reverse slope in correspondence with the anticline axial culmination; it is bordered at the rear by a NNW-SSE oriented, dextral, strike-slip fault zone and has an E-W direction of rock mass deformation. Closer to the southern plunging area of the anticline, gravity-driven phenomena show instead a N-S and NW-SE direction, influenced by bedding attitude.3D topographic models illustrate the relationship between deep-seated gravitational slope deformation and massive rockslope failures. The Campo di Giove rock avalanche, a huge Quaternary failure event, was the result of an instantaneous collapse on a mountaine slope affected by a long-term gravity-driven deformation. © 2003 Elsevier B.V.

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
Massive rock-slope failure in the Central Apennines (Italy): the case of the Campo di Giove rock avalanche. Bullettin of Engineering Geology and the Environment
No full textThe study of catastrophic rock slope failure is of great relevance as such phenomena can potentially occur at the intramontane, more urbanised areas, or in developing tourist areas such as the Maiella National Park. They must therefore be considered in landslide risk assessment exercises. This paper describes the Quaternary Campo di Giove (CDG) rock avalanche which occurred along the western edge of the Maiella Massif in the central part of the Apennines, Italy. The aim of this work is to contribute to the present debate about the nature of large-sized, Quaternary debris deposits of the central Apennines that have been controversially interpreted in the last decades as moraine, tectonic breccias or landslides and to provide an example of a rock avalanche that was strongly controlled by local geomorphic conditions. Field evidence, supported by morphometric and sedimentary analysis of clastic deposits, has demonstrated that the material originated during a rock avalanche event which occurred in a significantly different geomorphological setting. The control on the depositional mechanism by the Middle Pleistocene landscape is revealed by the reduced lateral spreading and the evidently asymmetric shape of the accumulation area
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
