Objective and subjective assessment of pockets of quiet inside historical urban areas
No full textMany studies have highlighted the relationship between exposure to high noise levels and
adverse health effects. Noise pollution is, for example, responsible for some detrimental
psychological and physiological effects. WHO estimated that, in Western Europe, due to
environmental noise the DALYs (Disability-adjusted life years) lost, and directly connected
only to noise annoyance, are about 654.000 years. With this premise, urban sound planning
should take into account the restoring capacities for the population that quite areas, such as
urban green parks, can perform. Unfortunately, within historical city centers, these areas
are generally missing and it is quite impossible to consider the design of new parks. A
previous research showed that, potentially, a capillary presence inside the urban context of
cloisters and courts could represent a valid alternative. The aim of this research is to analyze, with a multisensory approach, how spending time inside cloisters, courts and in general other spaces of historical and cultural value can influence the well-being of the population and compensate the noise stress in urban areas. Subjective Questionnaires, Physical Measurements and the evaluation of the Qualitative Aspects (QualiAs) of sites were carried out and statistically analyzed
Ricostruzione virtuale di allestimenti e rappresentazioni tramite game engine
No full textLa nascita di tecniche di simulazione e rappresentazione digitale ha portato allo sviluppo di numerose applicazioni di Realtà Virtuale nel settore dei beni culturali e della progettazione. Molte utilizzano game engine, software in grado di riprodurre dinamicamente ed in modo realistico numerosi effetti caratteristici della visione e del suono. Una verifica preliminare delle funzioni utilizzate per la simulazione degli effetti acustici ha mostrato come molti di questi possano essere migliorati
The Restorativeness of Outdoor Historical Sites in Urban Areas: Physical and Perceptual Correlations
Full text linkGrowing tourist flows, which crowd ancient city centres, have modified their liveability and threatened conservation. They have increased the need for quiet places, primarily where green parks are missing. While previous studies have highlighted the possibility of reusing hidden sites of historical buildings, it is not clear if this scheme can also be applied in other contexts, and which physical or perceptual dimensions are mainly related to the restoration of these sites. If greenery and water elements induce positive effects on people’s well-being, we want to understand if the historical–artistic component can be just as important for people’s restorativeness. To this end, the physical and perceptual characteristics of 20 different sites in Naples and Istanbul were investigated through objective and subjective surveys. The results show that the sound levels inside sites cannot consistently account for the perception of the restorativeness in Italy and Turkey, while some sound level differences caused by outside noise could. Moreover, soundscape, appreciation, maintenance/management, and importance/relevance were the main perceptual dimensions describing these places. The importance/relevance dimension was strongly correlated with all the components of the restorativeness, especially with the fascination. These findings are consistent between the Italian and Turkish groups
The sound as factor of reuse of Cultural Heritage in a modern key.
No full textCultural heritage is one of the most important aspect of our historical memory which must be protected and valued. This can be done through the architectural conservation of historical buildings or through the valorisation of their cultural function. The sound can play a key role for these sites and for their reuse, implementing urban revitalization strategies and providing them new functions for the needs of society. Today many cultural sites already host temporary spectacles, such as: live music events, artistic exhibitions, musicals and theatrical performances; on the other side they could be used for the restoration of citizens and tourists. This paper shows the different uses of historical sites where the sound is used for human well-being and for conservative and regenerative purposes
Restorative urban spaces in Europe: comparisons of criteria and approaches in Germany and Italy
No full textGoing 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
