Digital Twin Earth Hydrology Evolution: Final Report
No full textThe overarching objective of Digital Twin Earth (DTE) Hydrology Evolution project has been to prototype a full advanced end-to-end demonstrator of DTE over the full Mediterranean region at high resolution in space and time (targeting 1 km and 1 hour) by extending the successful implementation of Digital Twin Earth Hydrology project that has been carried out over the Po River Valley in northern Italy. Specifically, DTE Hydrology has demonstrated the potential to advance towards an end-to-end reconstruction of the hydrological cycle at high resolution in space and time by an effective combination of state-of-the-art EO data, in situ observations, advanced hydrological and hydraulic modelling, AI and advanced digital platform capabilities.

INFLUENCE OF HYDRAULIC GEOMETRY RATIOS ON THE ENTROPY PARAMETER IN OPEN CHANNEL FLOW
No full textThe way to evaluate the entropy parameter M through the ratio between medium and maximum velocity, Φ(M), still represents a relevant issue feeding a reach discussion among researchers. The invariance of Φ(M) for sections along the same river only at high flow seems to be consistent while for low stage Φ(M) can be affected by the influence of roughness, through the relative submergence as well as the aspect ratio related to the cross section geometry. Moving from these bases, using laboratory and field data, the classical hydraulic relationships on entropy velocity profile, uniform flow and regime theory, a predictor for entropy parameter is proposed for open channel flow. The work proposes general relationship existing between the parameter Φ(M) and the relative submergence taking into account the aspect ratio of the flow. The relationship has been applied to a set of experimental velocity data collected both in laboratory and in field, showing a good response of the theoretical model but selecting different behaviour dependent on the roughness scale. In fact, Φ(M) is strongly influenced by the ratio depth/roughness for values less than 4 when large and intermediate roughness scale occurs, while it might be assumed almost constant for small roughness scale
Climate Change and Decision Support Systems for Water Resource Management
No full textAbstractThe management of water resources always requires more and diverse approaches in which multiple skills and capacities are nested together, especially when critical situations are taken into account, such as climate change scenarios. The SimBaT software is a Decision Support Systems for water resource allocation and management. In this study, SimBaT is applied to the Montedoglio reservoir in the Tiber River Basin (Central Italy). The case study highlights how this methodology can be applied for a proactive management of critical scenarios in periods of drought due to climate change hypothesis
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
