Integrazione di fonti, applicazioni GIS e modelli tridimensionali come specchio per riflettere le città in movimento: un focus su un’area di studio del “Municipio Roma III”
No full textIl presente lavoro pone l’attenzione su un’area di studio del “Municipio Roma III” caratterizzata, nel
corso dei decenni, da profonde trasformazioni, con un notevole aumento della densità demografica ed edilizia e del traffico veicolare, e con considerevoli modificazioni pure in termini di servizi,
strutture e attività commerciali. Soprattutto negli ultimi vent’anni è nettamente cambiata anche la
tipologia degli edifici residenziali e sono sorti grandi complessi abitativi serviti, nelle vicinanze, da
imponenti esercizi e centri commerciali, assenti sino alla fine del secolo scorso, e da verde urbano,
con aree interne attrezzate, contornato da piste ciclabili e pedonali. Le dinamiche in atto hanno
comportato un progressivo riempimento degli spazi, spostando le soglie dell’abitato verso i limiti
interni del Grande Raccordo Anulare di Roma (GRA). Per supportare l’analisi geospaziale, un esame particolareggiato delle classificazioni d’uso degli edifici e un’efficace geovisualizzazione, sono
state prodotte varie applicazioni in ambiente GIS, mediante creazione di geodatabase, integrazione di dati e fonti plurime, georeferenziazione di cartografie e immagini satellitari, elaborazione
di mappature digitali e modelli tridimensionali. Continuative indagini sul terreno hanno, inoltre,
permesso di validare i dati riportati in fonti cartografiche ufficiali, quali la Carta Tecnica Regionale
Numerica (CTRN), individuando disallineamenti e destinazioni d’uso da aggiornare-modificare, per
giungere ad accurati prodotti di output (in progress), risultato dei dati della CTRN e della successiva validazione-rettifica. Dalle metodologie e dai procedimenti adottati sono derivate mappature
di dettaglio in pianta che mostrano – oltre alle trasformazioni registrate nel tempo e alle aree di
intensa crescita edilizia – le differenze tra le destinazioni d’uso di alcuni edifici come risultano
dalla CTRN e come si presentano dopo i rilievi di controllo sul terreno, fino a identificare intere
concentrazioni di fabbricati che hanno richiesto una specifica variazione. Al tempo stesso sono
state testate procedure che hanno permesso di raffinare i dati contenuti nelle fonti ufficiali, quali
la CTRN, trasferendoli in modelli tridimensionali che consentono di fornire dei carotaggi circostanziati, atti a evidenziare la compresenza di più destinazioni d’uso in un singolo edificio, aspetto che
invece rimarrebbe celato in assenza di appositi accorgimenti e criteri di rappresentazione
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
Emergency Department Overcrowding. A Retrospective Spatial Analysis and the Geocoding of Accesses. A Pilot Study in Rome
Full text linkThe overcrowding of first aid facilities creates considerable hardship and problems which
have repercussions on patients’ wellbeing, the time needed for a diagnosis, and on the quality of
the assistance. The basic objective of this contribution, based on the data collected by the Hospital
Policlinico Umberto I in Rome (Lazio region, Italy), is to carry out a territorial screening of
the municipality using GIS applications and spatial analyses aimed at reducing—in terms of
triage—code white (inappropriate) attendances, after having identified the areas of greatest provenance
of improperly used emergency room access. Working in a GIS environment and using functions for
geocoding, we have tested an experimental model aimed at giving a close-up geographical-sanitary
look at the situation: recognizing the territorial sectors in Rome which contribute to amplifying
the Policlinico Umberto I emergency room overcrowding; leading up to an improvement of
the situation; promoting greater awareness and knowledge of the services available on the territory,
a closer relationship between patient and regular doctor (general practitioner, GP) or Local Healthcare
Unit and a more efficient functioning of the emergency room. In particular, we have elaborated
a “source” map from which derive all the others and it is a dot map on which all the codes white have
been geolocalized on a satellite image through geocoding. We have produced three sets made up
of three digital cartographic elaborations each, constructed on the census sections, the census areas
and the sub-municipal areas, according to data aggregation, for absolute and relative values, and
using different templates. Finally, following the same methodology and steps, we elaborated another
dot map about all the codes red to provide another kind of information and input for social utility.
In the near future, this system could be tested on a platform that spatially analyzes the emergency
department (ED) accesses in near-real-time in order to facilitate the identification of critical territorial
issues and intervene in a shorter time to regulate the influx of patients to the ED
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
