No full textGeomorphologic evolution and neotectonics of the Sulmona intramontane basin (Abruzzi Apennine, Central Italy)
No full textThe Sulmona intramontane basin, elongated NW-SE according to the main tectonic structures of the area, is the easternmost of numerous tectonic depressions which characterize the inner part of Central Apennines. Although it is NW-SE trending, the basin contains oriented N-S and E-W tectonic structures just a few kilometres to the north and to the east. Such depressions have been formed during Middle-Upper Pliocene, after the end of the main tectogenetic phases of the Apennine chain. In order to outline the geomorphologic evolution of the area, detailed geological and geomorphologic investigations have been carried out, basing on both air-photo interpretation and field survey. The resulting framework is the following: a) formation of a half-graben depression (probably Upper Pliocene); b) formation of alluvial fans (Morrone area) (Lower Pleistocene); c) sedimentation in lacustrine-swampy environment (Middle Pleistocene); d) sedimentation of alluvial conglomerates (Sulmona surface) (late Middle Pleistocene - Upper Pleistocene); formation of alluvial fans and fluvial terraces (late Middle Pleistocene - Upper Pleistocene); e) deposition of recent and present-day alluvial sediments (Holocene). Tectonic activity, producing E-W and NW-SE trending faults, afected the area since half-graben formation up to present times. This sequence of events is also recorded in other similar depressions (Rieti, L'Aquila, Fucino) and may be considered representative of the Middle Pliocene-Quaternary evolution of Central Apennines
Some examples in the field of Geotourism in Emilia Romagna, Marche and Abruzzo Regions (Northern-Central Italy)
No full textItaly is a country with a rich natural heritage that is having difficulty in finding the right areas for acquiring knowledge, protection and improvement. In particular, the geological component of the landscape has not yet acquired a sufficient value as a cultural asset which people can learn about and share. Within the Italian territory geotourism activities and products are recently widespread. In this work examples of activities on geotourism in Emilia Romagna, Marche and Abruzzo regions are described. They are focused particularly on: analysis and enhancement of protected areas and geosites; geotourist and tourist-environmental maps; geological itineraries; portable and on-site geological illustrative materials.The described examples illustrate the documents implemented for the enhancement of the geological (s.l.) landscapes, at different spatial (from regional to local) and temporal (from Trias to Holocene and present) scales. This is focused on developing the sensitivity of people to read in the landscape long term temporal scales processes, that lead to the present landscape of a region, as well as short term temporal scale processes characterising the resource management or the local geological and geomorphological risks.The examples include activities at regional and institutional level, as well as at university level, in same cases in collaboration with upper school institutions. They also include activities developed specifically for tourism at local and regional scale or private initiatives, within the Park areas or within the Italian Association for Geology and Tourism. Besides the several possible approach to geological heritage enhancement, they show a different development level of geotourism in Italy. Indeed, only a wide interregional tourism network integrating initiatives targeted at various potential users and connecting universities, local and regional institutions, Parks and local reserves, schools, private initiatives etc., can lead to reach the goal in term of educational dissemination of geological and geomorphological themes, awareness of the complex meaning of the landscape. The integrated approach to the discovery of geological heritage - as presented in this work - through various tools and activities and targeted at various potential users can be summarised by quoting a famous statement by Marcel Proust: “the real voyage of discovery is not in seeking new landscapes but in having new eyes”
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
