Software previsionale acustico per esterni: un nuovo approccio multialgoritmo e multipiattaforma
No full textSimplified mapping algorithm for fast surveys, requiring minimal input data
Full text linkWhilst currently available programs for computing noise maps become even more
complex, there are cases where the usage of highly detailed algorithms and
procedures is meaningless, because the input data for such processing is simply not
available. So it is often seen that a very complex and theoretically very accurate
simulation system is providing objectionable results, because the user had to "guess"
for all the required input data which were not known.
The paper describes the algorithms employed in the program Citymap 3.0. This
software is very simple to use, requires just a minimal geometrical description of the
site, of the sources and of the receiving areas. The algorithms employed are strippeddown
versions of the computational methods currently mandatory in Italy, after the
EC directivity on environmental noise has been converted into Italian Law DL194 of
19/08/2005. Namely, the propagation algorithms are fully compliant with NMPBRoutes-96
for the road noise, with Reken-en Meetvoorschrift Railverkeerslawaai '96
for the railway noise, and with ISO 9613/2 for industrial sound sources. The program
imports easily geometrical data from most CAD and GIS packages, and asks only for
minimum information about sound sources and receivers. Thank to a new, fast
computational engine, the program can map with high spatial resolution large areas,
even in presence of a lot of obstacles and on arbitrarily-shaped terrains. As the
variance due to introduction of guessed input data is reduced, the results are often
more reliable than those of theoretically more accurate models, which are usually
very sensitive to errors in the input data.
Some comparative results are presented, verified by measurements in the field,
for demonstrating the above assertion

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
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
