Geomatics to support the environmental impact assessment in renewable energy plants installation
No full textProjections to 2020 indicate that renewable energy sources (RES) could cover, from 20 to 30 percent of the world's energy needs. To implement an effective e-governance in this direction, it is necessary to implement new methodologies to support decision-making in the local energy planning. The environmental impact is one of the main concern existing at different levels, in addition to the growing soil consumption in Europe. A significant problem for some types of plants, mainly solar and wind power, is the interaction of the devices with the surrounding environment, with possible negative effects in terms of visual impact and soil consumption. It is, therefore, very important to define which weight can have different impacts and to consider all possible scenarios. This work proposes a methodology to investigate, through some specific indicators, these impacts and to support territorial planning processes for the best choice of supply from RES. The processing of geospatial data and environmental information, collected at different scales, has been conducted through the use of GIS tools, allowing the implementation of a criticality index, as an indicator related to weight of the impacts that the construction of RES plants can have on the surrounding environmental features. © 2014 Springer International Publishing
Stima del potenziale energetico associato al moto ondoso in regioni campione della costa italiana
Full text linkNel corso dell’attività svolta nella precedente annualità era stata prodotta una mappa
del potenziale energetico ricavabile dal moto ondoso per l’intero bacino Mediterraneo.
Questi risultati sono stati analizzati con maggior dettaglio nel corso di questa annualità
mostrando, per alcuni punti campione, la distribuzione di energia in funzione di periodo
e altezza significativi. Dall’analisi della climatologia, calcolata sul decennio 2001-2010,
la costa occidentale della Sardegna e la zona nord-ovest della Sicilia erano risultate le
più promettenti dal punto di vista energetico. Un approfondimento dello studio relativo
ha quindi comportato la realizzazione di simulazioni modellistiche a più alta risoluzione
per queste due zone. Una terza zona analizzata con maggiore dettaglio è quella circostante l’isola di Pantelleria, che,anche se caratterizzata da una energia media inferiore, può risultare interessante per lo sfruttamento di energia ondosa a causa delle particolari difficoltà di approvvigionamento energetico. Sono quindi state effettuate simulazioni climatologiche per queste tre zone, alla risoluzione spaziale di 1/120°, corrispondente a distanze inferiori al chilometro. In questo caso le simulazioni sono state realizzate utilizzando il modello SWAN (Simulating WAves Nearshore) più idoneo alla simulazione in zone caratterizzate da acque poco profonde. Le condizioni laterali sono state ricavate dalle simulazioni effettuate durante l'annualità precedente e sono stati utilizzati come forzanti superficiali gli stessi campi di vento provenienti dal Centro Europeo per le previsioni meteo a medio termine (ECMWF). Nella presente relazione, dopo una descrizione delle equazioni di base del modello SWAN utilizzato, sono presentate le mappe di potenziale energetico ricavato dal moto ondoso relative ai risultati climatologici per le tre zone
Geomatics in Climate Services and Local Information: A Case Study for Mediterranean Area
No full textThis paper describes a new idea and methodology developed for overcoming problems linked to the climate changes science and how to make them effectively accessible by end users. In today’s scientific approach, communication, on climatic information and on climatic changes condition, has to be clear, accessible and perceptive to everyone, to definitely address the right interest on such problem. Results coming from climatic changes Research and Development projects, in addition to being accepted by policymakers, that have to take future decisions and practical actions to mitigate their possible negative effects, must also be recognized and believed by ordinary citizens that have to understand and accept restrictions, for example in energy consumptions, potentially affecting their habit of life. Accordingly, it will be necessary to regenerate policy-making so as to make it more direct and potentially open to networking interactive communication tools. The present work substantially deals with the problem of the outcomes communication both in the field of climatic studies both of climatic trend conditions, also at a long-term scale. Furthermore, it has been observed that one of the most widely discussed issues, in addition to that of the uncertainty of the climatic condition predictions, is the data/results communication to policy makers, stakeholders, environmental agencies, citizens, etc. © Springer International Publishing Switzerland 2015
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
