La nuova specifica tecnica UNI/TS 11445 - Impianti per la raccolta e l'utilizzo dell'acqua piovana
No full textIl lavoro fornisce un commento critico alla specifica tecnica "UNI/TS 11445 - Impianti per la raccolta e l'utilizzo dell'acqua piovana", alla cui redazione l'autore ha partecipato in qualità di membro del gruppo di lavoro ad goc incaricato della stesura. Si tratta di un tema molto delicato nel quadro più generale degli aspetti tecnologici della progettazione sostenibile, privo di testi di riferimento normativo, fino al momento della redazione del documento tecnico in esame. Partendo dalla collocazione dell'argomento nel contesto nazionale, viene indicato il campo di applicazione del documento tecnico, ne viene commentata la struttura, con riferimenti dettagliati agli aspetti salienti, concludendo con delle note finali e l'indicazione delle fonti di bibliografia. | This work provides a critical commentary on the Italian technical standard "UNI/TS 11445 - Installations for the harvesting and use of rainwater", which the author helped to draft as a member of the ad hoc work group in charge of its preparation. Rainwater harvesting is a very sensitive issue in the broader context of the technological aspects of sustainable design. Until this paper was published, there were no reference texts for the regulations governing rainwater harvesting in Italy. The paper begins with a background of the topic in the national context, and goes on to explain the scope and structure of the standard. There are detailed references to the most important aspects, along with final notes and bibliography sources
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
WFC3 SMOV Proposal 11445- IR Geometric Distortion Calibration
No full textThe goal of WFC3 SMOV program 11445 is to obtain a coordinate system free of distortion to a precision level of 0.2 pixels or ∼ 26 mas. The astrometric calibration of WFC3/IR is based on two astrometric standard fields: a reference frame in the globular cluster 47 Tuc and in the Large Magellanic Cloud. Both 47 Tuc and the Large Magellanic Cloud, observed with the F160W filter and with dither patterns, have been used to determine the geometric distortion in WFC3/IR. We used a 4th order polynomial model to derive the geometric distortion in the IR channel relative to the distortion free coordinates of our astrometric fields. As a result, the geometric distortion can be successfully corrected down to the precision level of 8 mas, which is three times better than the required precision. 1
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
