Geomorphological map and main features of the area between Mt Fumaiolo and Valsavignone, Upper Tiber River Basin, central Italy | Carta e Lineamenti Geomorfologici dell'area compresa tra il M. Fumaiolo e Valsavignone (alto bacino del Fiume Tevere)
No full textViene proposta la cartografia degli elementi geomorfologici salienti della porzione più settentrionale del bacino del F. Tevere, al confine tosco-romagnolo. Lo studio è finalizzato alla definizione dei parametri che regolano la dinamica dei versanti e la dinamica fluviale ed alla identificazione delle tendenze evolutive di tale area, alla luce dell'importanza che riveste nella gestione e pianificazione territoriale per essere interessata, poco più a valle, dalla presenza di una delle dighe più importanti dell'Italia centrale, quella di Montedoglio (AR)
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
The Evolution of Montebestia Landslide (Umbria, Central Italy). Site Investigations, In-Situ Tests and GPS Monitoring
No full textThe study of Montebestia landslide (Umbria, Central Italy) is related to the general analysis of the types and causes of landslides which frequently involve the continental plio-pleistocenic sediments (gravels, sands, silts and clay) of the fluvial-lacustrine facies of the "Ancient Tiberian Lake Basin" ("Villafranchiano"Auctorum). The geological structure of the area is characterised by the presence of apenninic master falults and by antiapenninic joints and faults influencing the evolution of the landscape and the hydrographic network. The landslide is located in the Upper Tiberian Valley, next to Montone (in the province of Perugia). The stratigraphic sequence involved by the movement comprehends: silts (from clayey silts to sandy silts) with thin layers of gravels and sands; upper gravels and sands, bringing up the series. The dip of the clastic complex is towards SW, with an angle if inclination near to the slope inclination. The morphological evolution of the area was reconstructed by ancient cartographic documents and by aerial photos related to several flies (from 1954 to 1991). It shows that the lithological, structural and stratigraphic features were able to guide type, location, geometry and evolution of the mass movement. The results of the monitoring carried out by an inclinometer (to measure deep displacement), a GPS network (to measure surface movements) and piezometers (to control the relationships with groundwater) show a differentiated evolution, according to the type of mass movement recognisable in this area: multiple surface movements situated at a shallow depth and very slow movements (which are nonetheless constant over time) located at a major depth along a slide surface, which guided the various evolutive states. So this landslide, that can be classified "complex landslide" according to UNESCO (WP/WLI, 1993a; 1993b) owing to the described features, represents a significant example of the gravitational phenomena occurring in the clastic plio-pleistocenic sediments of the tuscan-umbrian "Villafranchiano" Auctorum, in Central Italy
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
