(No) City for old men
No full textIn this paper, we report and analyse, for 83 European cities, the share of respondents aged 65 years or older agreeing that the city where they live is a good place to live for elderly people. Results contribute to identify common patterns and inform policy makers
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
Acoustic correction of a renaissance period hall
No full textMedieval and Renaissance halls are often used for musical events or conferences. These rooms have vaulted ceilings, while the surfaces are covered with plaster and marble. The acoustics of these places are not optimal for listening to musical performances or conferences. To make these environments acoustically usable, an acoustic correction must be made. A room, built during the Renaissance period used for cultural events, was considered as case study. From the acoustic measurements, it results that at mid-frequencies the reverberation time is about 4.5 seconds. The evaluation of the acoustic correction was carried out with a software for the architectural acoustics. The virtual model was analyzed first in the initial configuration and then with the insertion of sound-absorbing panels on the walls and under the ceiling with the vault. Subsequently, the acoustic correction was performed by installing sound-absorbing panels in the room. Acoustic measurements were taken with this new configuration, in the absence of the audience, and the reverberation time at the mid-frequencies was reduced to 2.0 seconds as presented in the design project
Monitoraggio di BTEX in uno street canyon profondo
No full textE’ stata condotta una campagna di monitoraggio di BTEX (benzene, toluene, etilbenzene, m- p- e o-xilene) in uno street canyon profondo nell’area urbana di Napoli. I prelievi sono stati effettuati utilizzando cartucce adsorbenti. In simultanea si sono effettuate misure del traffico e dei parametri meteorologici. Dai risultati è emerso che i livelli di concentrazione di benzene hanno superato, per circa un quarto dei campionamenti, il limite imposto per l’anno 2007 dalla Comunità Europea, pari a 8 μg/Nm3. La correlazione tra i livelli di concentrazione dei BTEX e le emissioni veicolari è risultata bassa. I valori più elevati del coefficiente di correlazione si sono riscontrati per le emissioni dei veicoli a due ruote. La differenza di concentrazione sui due lati della strada, valutata mediante un’analisi statistica, è risultata non significativa. Quest’ultimo risultato può essere di particolare interesse per lo sviluppo di modelli parametrici specifici per street canyon profondi
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
