GIS-based morphometric study to genetically characterize dolines in the SE sector of the Classical Karst Region (NE Italy)
No full textStarting from October 2022, in collaboration with ISPRA (Italian Institute for Environmental Protection and Research) and the Geological Survey of the Friuli Venezia Giulia Region, activities have been launched for the creation of the Sheet 110-131 ”Trieste-Caresana” of the Italian Geomorphological Map as part of the CARG project. The territory to be mapped includes a section of the Italian part of the Classical Karst Region, the one limited by the village of Aurisina (NW) and the Rosandra Valley (SE). The Karst area is globally renowned for its pronounced expression of the karst processes and the wide variety of landforms. For these reasons it has represented the cradle of karst studies since the end of the 17th century.
In the Classical Karst area, dolines are probably the most distinctive landforms, being widespread and characterized by significant variety in shapes and sizes. One of the main challenges related to characterization of dolines in a mature karst context is the difficulty in
determining their genetic process with a defined, large-scale applicable criterion. The dissolution process can, over time, conceal markers that allow to clearly distinguish on the field a doline formed by the collapse of a cavity from one generated by the solution of bedrock. A
morphometric approach is proposed to classify dolines in an intensely karstified area on the basis of the predominant genetic process (collapse or solution), using slope steepness as the main parameter.
The carrying out of the remote sensing and field surveying activities, as part of CARG project, has facilitated the collection of a substantial amount of new data on epigean landforms. Specifically, a new high-resolution (0.5 meters) Digital Elevation Model has enabled a
more accurate delineation of these features for morphometric analyses. All karst depressions and their bottoms were digitized through remote sensing starting from the homogenization of existing data and with the support of field surveys. A total of more than 7,000 dolines
have been identified in a total surface area of 115 km2.
Information regarding the edges and bottoms of the dolines have been processed using the GIS zonal statistics tool. The areas related to the slopes of the dolines have been extrapolated and then parameterized according to their steepness. This methodology has allowed for the formulation of a preliminary genetic model for dolines in the study area.
To validate this model, a sample of dolines with clearly defined genesis has been selected. Geophysical investigations, as well as a borehole, have been planned to verify the GIS-based procedure. The geological context has been also considered, paying particular attention to the dip of the strata

No full textIl progetto risponde alla crescente domanda che sale da tutto il mondo occidentale di ritrovare nella fitoterapia quei rimedi che si sono accreditati nel tempo della storia umana;
praticare l’automedicazione usando rimedi più soft dei comuni farmaci.
La mission di ISHTAR consiste nell’uso della “FORZA ROSSA”, cioè nell’uso dei pigmenti e principi attivi presenti in frutta e ortaggi rossi (antocianine, resveratrolo, acido ellagico e licopene) che hanno la proprietà di combattere e prevenire obesità, sindrome metabolica e diabete, tre diffuse patologie tipiche dei nostri tempi.
Queste sostanze, che hanno effetti positivi sul tessuto grasso, sui muscoli scheletrici e sul tessuto epatico, provocano l’abbassamento del livello di glucosio nel sangue, l’aumento del metabolismo ossidativo dei grassi e in definitiva un effetto dimagrante ed antidiabetico
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
