Public communication and pandemic crisis: The case of the Municipality of Peccioli
No full textIn the last twenty years public communication has profoundly changed, and institutions have begun to increasingly use methods based on listening, participation and citizen engagement. This paper explores public communication during the Covid-19 crisis, focusing on the local context of Peccioli. In light of the initiatives implemented by the Municipality, it addresses these research questions: How do citizens consider public communication during the emergency, and which channels have been mostly used to stay updated on municipal initiatives? How do citizens evaluate the emergency management by the municipality, and how do they suggest improving it in the event of a return of the virus? Through a quali-quantitative approach 268 structured interviews were conducted. Participants were selected from the municipal registry following a proportional allocation based on three sociodemographic variables: age, gender and place of residence. The findings highlighted a) information practices based on the integration of official and unofficial channels and traditional media and digital platforms; b) preference for one-to-one communication, mediated and not; and c) highly positive perception of the work of the municipality
Analisi critica delle metodologie di prova a fatica su carrozzine per disabili secondo iso 7176-8
Full text linkScopo del lavoro era la valutazione critica dei metodi di prova a fatica su carrozzine per disabili attualmente allo studio del gruppo di lavoro ISO TC 173 – SC1 – WG1 incaricato di discutere la revisione della norma ISO 7176-8:1998 relativa ai metodi di prova. La versione attuale richiede il superamento sia di una prova su banco a rulli con ostacoli di 12 mm di spessore, impattati per 200'000 cicli dalla carrozzina zavorrata con manichino normato, sia si una prova di caduta da 50 mm di altezza ripetuta per 6666 volte. L’evidenza tecnico scientifica della correlazione tra sollecitazioni al banco e vita su strada è del tutto mancante: si è dunque intrapresa un’attività mirata da un lato all’acquisizione di dati su strada per la stima degli spettri di carico significativi, dall’altro al monitoraggio dei livelli di sollecitazione che gli attuali metodi di prova producono per caduta sulle carrozzine, nonché alla valutazione di eventuali metodi alternativi alla caduta di 50 mm ed integrabili in banchi prova a rulli con camme di specificata altezza. Il lavoro ha consentito di acquisire dati di carico e di accelerazione all’asse ruota posteriore utili alla definizione di prove equivalenti ad una data missione obiettivo delle carrozzin
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
Giochi di specchi: Racconti ed esperienze dell’essere NEET nella stampa e nella vita quotidiana
No full textL’acronimo NEET indica i giovani (15-29 anni) non impegnati in attività lavorative, formative o di aggiornamento/tirocinio. La presente ricerca ha approfondito tale questione come rappresentazione sociale, conducendo due studi convergenti rivolti all’analisi di cinque quotidiani nell’arco di dieci anni e di interviste episodiche a venti protagonisti. I risultati mostrano che la stampa presenta la questione in termini di assenza di lavoro e con aspetti emotivamente negativi; meno evidenti sono i riferimenti alla formazione e all’educazione permanente. Secondo i protagonisti, questi aspetti sono in parte bilanciati da richiami alla possibilità di avere tempo per sé e all’opportunità di mettersi in gioco. Lo sguardo dell’Altro si riverbera tuttavia nei vissuti personali, alimentando una spirale negativa nei meccanismi di autodefinizione
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
