GIScience e i paesaggi d’acqua: prime considerazioni sull’applicazione di sketch map tool nel caso studio della diga di Occhito
No full textFra i possibili strumenti per studiare le connessioni fra popolazione e paesaggio ci sono i Public Participatory GIS. In quanto mezzo che hanno ancora un utilizzo limitato nella creazione di nuovi dati geografici attraverso il coinvolgimento dei locali, risulta quantomai importante analizzarne opportunità e limiti. Il contributo fornisce delle prime riflessioni sull’impiego della piattaforma Sketch Map Tool nell’analisi dei paesaggi d’acqua. Tale tool permette di condurre varie attività di mapping partecipativo, che vanno dalla preparazione dei dati, alla raccolta in campo e poi all’analisi dei dati on desk. Il lavoro presenta il processo partecipativo adottato nell’area interna del Fortore (Campobasso, Molise), e nello specifico nell’area in prossimità della diga artificiale di Occhito
IL PROGETTO NESIS (NEAPOLIS INFORMATION SYSTEM): ANALISI TERRITORIALE DIACRONICA DEL SETTORE NORD-OCCIDENTALE DELLA CITTÀ DI NAPOLI
Full text linkSpatial distribution analysis of ground-mounted photovoltaic systems: a spatial comparison beetween Lombardy and Apulia
Full text linkLa transizione energetica volta a raggiungere gli obiettivi di indipendenza dalle fonti energetiche fossili e di neutralità climatica determina che l’energia fotovoltaica assuma un ruolo estremamente rilevante. Tuttavia, la diffusione di impianti fotovoltaici a terra solleva diverse questioni circa l’allocazione ottimale dell’uso del suolo, in relazione anche a diversi fattori quali l’urbanizzazione, l’agricoltura intensiva e lo sviluppo industriale. In questo contesto viene affrontata la questione della gestione sostenibile del suolo, evidenziando l’impatto ambientale dell’impermeabilizzazione di vaste aree di territorio con impianti fotovoltaici. Questo elaborato utilizza una analisi volta a cogliere la localizzazione spaziale dei principali cluster di impianti fotovoltaici a terra per le regioni di Puglia e Lombardia. Questa metodologia permetterà quindi di ricostruire un quadro dettagliato della relazione tra consumo del suolo e diffusione degli impianti fotovoltaici, evidenziando sia gli aspetti positivi inerenti alla produzione energetica rinnovabile che le implicazioni sugli aspetti di sostenibilità ambientale derivanti da un aumento costante nel consumo del suolo.The energy transition aimed to achieve the goals of independency from fossil energy sources and climate neutrality determines that photovoltaic energy will assume an extremely relevant role. However, the widespread adoption of ground-mounted photovoltaic installations raises several questions about the optimal allocation of land use, in relation also to several factors such as urbanization, intensive agriculture and industrial development. In this context, the issue of sustainable land use management is addressed, highlighting the environmental impact of sealing large areas of land with photovoltaic installations. This paper uses an analysis aimed at capturing the spatial location the main clusters of ground-mounted photovoltaic installations for the Apulia and Lombardy regions. This methodology will thus allow reconstructing a detailed framework of the relationship between land consumption and the spread of photovoltaic installations, highlighting both the positive aspects inherent to renewable energy production and the implications on environmental sustainability aspects resulting from a steady increase in land consumption
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
