    Un Sistema Web-GIS per il supporto dinamico all’attività di Agenda 21 Laghi

    Il presente lavoro illustra le soluzioni adottate ed i risultati ottenuti nell'ambito di un progetto svolto in collaborazione tra il Dipartimento di Informatica e Comunicazione (DICOM) dell'Università degli Studi dell'Insubria, sede di Varese e Agenda 21 Laghi. Il progetto ha portato alla realizzazione di un Sistema WebGIS in risposta alla duplice esigenza di rendere fruibili le informazioni relative alle diverse attività di ricerca e studio svolte sul territorio di Agenda 21 Laghi ad un'utenza allargata e diversificata, e di offrire nel contempo, ad un’utenza specialistica, un supporto per la pianificazione e lo sviluppo integrato di attività future. Il WebGIS integra quindi due modalità di visualizzazione ed analisi dei dati, semplificata ed avanzata, rivolte rispettivamente ad utenti generici ed esperti del territorio e dell’ambiente. I dati sono composti da un insieme di strati informativi di contorno presi dal sito della regione Lombardia ( uso del suolo, confini comunali, viabilità, ecc), da una serie di strati raster mutuamente esclusivi (ortofoto, Carta Tecnica Regionale 1:10000 e 1:50000) e dai diversi studi condotti sul territorio di Agenda 21 Laghi. Il sistema è stato realizzato con strumenti open source: PostgreSQL e PostGIS per la creazione del geodatabase, Apache come web server, MapServer per la pubblicazione dei dati georeferenziati

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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 text
    We 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
