VGI AND WEB 2.0: POLITICS IN THE TIME OF TWITTER
Full text linkIl presente contributo si articola in due parti che mirano a esplorare la rappresentazione
del luogo attraverso informazioni georeferenziate generate dagli utenti.
La prima parte, a carattere teorico e metodologico, analizza il contesto dell’informazione
geografica e le recenti innovazioni della cartografia online, con particolare attenzione
alla Volunteered Geographic Information (VGI).
La seconda parte dello studio verte sul caso di studio: verrà infatti mostrato come le
informazioni generate dall’utente possano essere utilizzate per analisi di carattere sociopolitico
e come possano essere create mappe tematiche con strumenti di mappatura
differenti. L’analisi prende in considerazione i tweet con geocode presenti su Twitter
relativi ad alcune delle principali personalità politiche italiane al fine di mostrare una
valutazione della popolarità e della percezione degli italiani nei confronti di alcune
delle principali personalità politiche italiane attuali.
L’articolo si conclude con una riflessione sulle potenzialità e i limiti, le opportunità e
le difficoltà, delle nuove applicazioni Web 2.0 con l’intento di mostrare che il dato e
l’informazione generati dall’utente possono svolgere un ruolo importante nella ricerca
geografica e nella cartografia, per aiutare a comprendere meglio fenomeni, nel nostro
caso politici, ma anche sociali ed economici.In this paper there are two main parts, which aim at exploring the representation of
place through georeferenced user-generated information.
The first part focuses on the main features of volunteered geographic information
(VGI) and open source mapping tools. The second part of the paper develops a case
study. It will be shown how user-generated information might be used for investigating
a social and political topic and how thematic maps representing the analysis may be
obtained with different mapping tools. That analysis has been developed using geocoded
tweets from Twitter, concerning some of the most important Italian politicians.
The paper closes with some remarks on the potentialities and the limits, the opportunities
and the difficulties of the emerging Web 2.0 applications and it aims at showing that user-generated data and information can play an important role in
geographical research and in mapping activities, to help to better understand political
as well as social and economical phenomenon

Citizen Science, territorio e comunità: prospettive geografiche per la ricerca e azione
Full text linkChi ha detto che la scienza è solo per gli esperti? In un mondo in cui la partecipazione attiva è più cruciale che mai, la Citizen Science sta rivoluzionando il modo in cui raccogliamo dati, generiamo conoscenza, costruiamo politiche pubbliche più informate e formiamo cittadini più consapevoli. Dai progetti di monitoraggio ambientale all’analisi dei dati crowdsourced, dalla pianificazione urbana partecipativa alla democratizzazione dell’informazione scientifica, questo volume – primo nel
panorama della ricerca scientifica in lingua italiana – esplora i pilastri della Citizen Science e il suo impatto su società e ambiente. Attraverso esempi pratici e riferimenti a casi innovativi, gli autori guidano il lettore alla scoperta di un ecosistema in cui cittadini, scienziati, istituzioni e comunità collaborano per affrontare le sfide globali.Who said science is just for experts? In a world where active participation of the population is more crucial than ever, Citizen Science is revolutionising the way we collect data, create knowledge, develop more informed public policies, and empower citizens. This volume, the first such research published in the Italian language, explores the pillars of Citizen Science and the impact of the practice on society and the environment, from environmental monitoring projects to crowdsourced data analysis, from participatory urban planning to the democratisation of scientific information. Through practical examples and references to innovative cases, the authors guide the reader to the unveiling of an ecosystem in which citizens, scientists, institutions, and communities work together to address global challenges
THE AIRIFICATION OF CITIES. MAKING SENSE OF THE IMPACT OF PEER TO PEER SHORT TERM LETTING ON URBAN FUNCTIONS AND ECONOMY
Full text linkThis paper explores spatial and economic dynamics arising from the diffusion of short termnletting across Italian cities. The study is based on a vast dataset comprising of all the properties listed on
the AirBnB website in 14 cities, during the year 2015. We start by examining the relationship between airbnb ́s offer and general tourist flows, and demonstrate a strong correlation between the two in all the cities considered, suggesting that airbnb accommodation is how a well established, integral component of the Italian tourist offer.
The core objective of the study is to look into the role of short term letting within the general dynamics of urban capital valorisation, and gain insight on the possible evolution of the urban functions of historic
centres. To this purpose we identified urban areas with the highest economic advantage of short-term letting versus traditional long-term residential letting. Our analysis suggests that landlords in the urban
cores of art cities may already be moving properties from the residential market to short term letting in great numbers, contributing to the decade-old social desertification and disneyfication of Italian historic
centres. This finding is also supported by the surprisingly high proportion of residential units in historic centres listed on airBnB and, among these, the overwhelming predominance of entire homes versus single
and private rooms. Such observations also seem to contradict AirBnB Inc. ́s narrative regarding the actors that mostly benefit from the platform - reportedly younger tenants struggling with high rents, and families making an extra income. Our results suggest that landlords may be those more interested in the opportunities afforded by the platform, rather than resident tenants.
The article concludes with a focus on two cities, Florence and Milan, which display extremely different spatial patterns of short term letting supply and demand, and an interesting relationship between the
distribution of airbnb clusters and urban phenomena of different nature, such as gentrification
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
