Caratteristiche acustiche interne di ambienti confinati. La UNI 11532 diventa una ‘serie’
No full textNegli ultimi anni, l'attenzione al comfort acustico negli ambienti di vita ha assunto un ruolo significativo in ambito internazionale come risposta ad un’esigenza oggettiva. Ne sono un esempio le recenti normative straniere che forniscono valori di riferimento per molteplici destinazioni d’uso quali aule scolastiche, luoghi di ristorazione, uffici e cosi via.
A livello nazionale, con l’emanazione del Decreto 11 Gennaio 2017 del Ministero dell’ambiente e della tutela del territorio e del mare – Adozione dei criteri ambientali minimi per gli arredi per interni, per l’edilizia e per i prodotti tessili ovvero dei Criteri ambientali minimi (C.A.M.) il legislatore ha riconosciuto l’importanza di questi criteri da adottarsi per gli edifici pubblici. Tre i punti fondamentali sanciti nel Decreto: distinzione tra edifici pubblici e privati; differenziazione tra isolamento acustico e comfort acustico; richiamo in un decreto con valore cogente delle norme tecniche UNI.
Per l’acustica interna di singoli ambienti, il riferimento normativo è la UNI 11532:2014; da qui l’esigenza di rivedere la norma al fine di rispondere pienamente alle attese legislative. Infatti Bandi e Gare d’Appalto Pubblici faranno riferimento ai C.A.M. e di conseguenza alla suddetta norma che pertanto dovrà avere obiettivi chiari, specifici metodi di previsione, specifici metodi di verifica e chiari elementi oggetto di verifica, ma soprattutto dovrà essere un riferimento per molteplici settori in cui le persone sono impegnate a comunicare, ascoltando o parlando, per lavoro o piacere.
Date le molteplici tipologie di ambienti coinvolti, si è reso necessario far evolvere la UNI 11532 in un pacchetto di norme che potessero, in modo più dettagliato, rispondere alle diverse esigenze, individuando obiettivi ad hoc e descrittori acustici rispondenti
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
The New Italian standard UNI 11532 on acoustics for schools
No full textIn Italy, the new UNI 11532 standard introduces requirements for acoustic comfort in different building typologies such as schools, offices and hospitals. In March 2018 the UNI 11532 - Part 1 "General requirements" was published, which includes the main descriptors related to noise, room acoustics and speech intelligibility to be considered for the design and verification phases. The drafting of Part 2, dedicated to schools, is now completed. This standard is voluntary for private constructions, but mandatory in the public sphere following the issue of the Ministerial Decree “Minimum Environmental Criteria (Criteri Ambientali Minimi or “CAM”) for the awarding of design and construction services for new construction, renovation and maintenance of public buildings”, dated 11 October 2017. The Decree explicitly refers to the UNI 11532 standard for the requirements to be guaranteed in public procurement. The underlying principles and criteria of the new standard in the case of schools, as well as comparisons with other standards in Europe, will be presented and discussed in this work
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
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
