Frasassi Caves and Surroundings: A Special Vehicle for the Geoeducation and Dissemination of the Geological Heritage in Italy
Full text linkOne of the most fascinating aspects of the work of geologist lies in knowing how to read the physical landscape as an expression of the geological and geomorphological phenomena that shaped the Earth’s relief over time. The necessity to disseminate these vast areas of knowledges and skills starts from here, with the aim to enhance the concept of geodiversity and to raise awareness for its protection and promotion. This work aims to share some examples of projects realized following the subscription of agreement between different public authorities in the Apennine territory of Marche Region in Italy, such as the Geology Section of the University of Camerino (MC), “Consorzio Frasassi” (which manages the underground karst complex of Frasassi caves) and municipality of Genga (AN), where Frasassi caves are located. Thanks to this partnership, our research group realized didactic geological notebooks for school groups visiting the caves and interactive museum laboratories in 3D, showing the geological evolution of the area. This sharing of knowledge will contribute to educate communities about the importance of the geological heritage. At the same time, this project can serve as motivation to establishing the same type of collaborations in those territories where similar projects can be replicated

Community-Based Approaches to Debris Flow Hazard Analysis in the Sibillini Mountain Range (Central Apennines, Italy).
No full textHerein, we propose new methods for interpreting the debris flow phenomena affecting the Sibillini Mountains (central Apennines, Italy), based on the main characteristics and mechanisms of these hazards and their associated risk, as studied by applying advanced GIS tools to a geodatabase including the morphometric parameters of many surveyed debris flows as well as topographic and climatic information. The study area is characterized by mainly calcareous lithologies belonging to the Umbria–Marche Succession, which are frequently covered by Quaternary continental deposits. Slopes and deep transversal valleys are strongly influenced by Pliocene–Quaternary tectonics. Our main objectives were (a) to provide a comprehensive survey of the local morphologies and dynamics of debris flows and localize, catalog, sample and implement them in a geodatabase, as well as monitor them; (b) to forecast potential future debris flows in the study area based upon their evolutionary processes (e.g., dynamic evolution of debris flows, time of recurrence, removed volume of materials) and, in doing so, evaluate hazards and risks for human activities, as well as possibly apply this prediction method to other areas with similar geological and morpho-climatic characteristics; and (c) to share scientific information with society, with the goal of involving citizens in a new and sustainable method of territorial management
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
Territorial knowledge and cartographic evolution
Full text linkThe role of geological and geotematic mapping has recently come to the forefront in spatial/environmental management. This paper aims to present some cases of boundary extension in the use of contemporary cartographic tools (GIS and WEBGIS). The potential of digital maps and associated databases offers a wide range of applications, responding to the urgent need to make available to users (practitioners in the technical sectors, planners and society as a whole) the most important concepts to concretely achieve better land management, active risk prevention and sustainable resource enhancement. The application of geomorphological maps to issues closer to society can effectively create its approach to more properly technical-scientific issues, fostering a shared awareness, useful in protecting and enhancing the fragile Italian territory. The described experiences focus on GIS, which confirms its effectiveness both for social involvement in environmental issues, and in territorial/environmental management
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
