The acoustical improvement plan as a process to re-establish acceptable acoustical conditions
No full textThe word “Acoustical Improvement Plan” indicates a set of provisions, related to
land management and suitable to reach the targets defined in the planning, with
particular reference to acoustical standards satisfaction.
The acoustical improvement plan could be interpreted as a loosening of the most
critical nodes checked by the comparison between the noise mapping and the
acoustical characterisation of a territory, but this interpretation couldn’t reply to
the most diffused question of acoustical quality. This condition derives by an
approach founded on a multiplicity of actions and provisions, able to implement
new logics in decisional processes, that determines the territory planning and
manages the transformation, with a particular attention to environmental noise
problems.
The purpose of this paper is to describe the plan identity, which isn’t represented
by a specific planning action, but it invests and interests in particular actions of
all politics of planning and territorial management, involving therefore the
necessity to coordinate and to interact with the main instruments of territorial
management.
The acoustical improvement plan won’t be the design of the intervention aimed
to restore the sound levels limits, but a process, structured as a set of provisions
and principles of urban planning and government of the territory, with the
purpose to re-establish acceptable acoustic conditions for the critical zones, but
also in order to prevent eventual future suffering
“Environmental limit values for habitat infrastructure works: the problem of the identification of parameters based on the exceptions to the law"
No full textNoise pollution, caused by traffic, industrial activities
is one of the main local environmental problems:
actually, about 20 percent of the European population
is highly annoyed by environmental noise. The
importance of this problem has been fixed by DIR
2002/49/CE, relating to the assessment and
management of environmental noise, with the aim of
containing and eliminating acoustical impact caused by
different sources, to improve or maintain
environmental acoustical quality.
Italian legislation identifies in the noise mapping,
(which consists in the subdivision of a land in areas,
acoustically homogeneous, where limit values are
fixed) the instrument put in charge for territorial
acoustical management: this instrument must be
suitable with the existent acoustical conditions to allow
favorable development territorial plans and an effective
land management.
The acoustical planning, in the case of particularly
event could have a particular meaning, being not only
an answer to territorial management, but also a
preliminary acoustical evaluation ex ante.
The noise mapping can represent a significant picture
of acoustical conditions before the construction of
infrastructure, such as roads or railways, to compare
with the acoustical predicted impact of the new source.
This research is about a study case, which aim is at first
the realization of noise mapping for an Italian little
town, with a project of a new road infrastructure.
The noise mapping which has been done on the whole
municipal territory had to confront with two aspects: a
new residential urban area and a natural park as
protected zone, areas with a good acoustical quality,
which will be involved in the construction of a new
infrastructure. In fact, the tunnel, which will connect
the existing roads and highways, will have the inlet and
outlet in these areas.
In this research an acoustical analysis of noise mapping
has been done, integrated with the new problems,
induced by the road variations and by its work
construction
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
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
