The Experience of Parametric modeling design GIS: An Abruzzo hamlet case study
No full textWith this research work, the aim is to structure an innovative modus operandi aimed at representing a
territory with a multi-scalar approach, consistent with vector modelling, which allows to make analysis
from an urban and architectural point of view in a synergistic way. The data at the base of this system
are GIS type, therefore georeferenced, associated with geometric primitives. The intuition lies in the
elaboration of three-dimensional vector models of even very large portions of territory, realized through
a visual scripting digital tool (Grasshopper) and processed in a NURBS modeling software. At this
stage of the research the attention is mainly focused on the faithful representation of the territory. The
case study presented is Arischia, historical center of the province of L'Aquila, located at the foot of the
Abruzzo Apennines. For the realization of the model we start from geotiffs of the DTMs that are
vectorized in order to get a three-dimensional grid of points that is used to create a NURBS surface
that represents the orography of the territory, roads and buildings. The use of NURBS mathematical
surfaces allows to lighten the computational burden, obtaining these results in a very short time. The
criticality of this methodology is mainly inherent in the availability of accurate spatial data and in some
manual operations to make the procedure work. Further development of this work will be the use of
remote sensing for perceptive comparison between these two methods of representation
Slow mobility-based representation of coastal territoryThe Costa dei Trabucchi case study
Full text linkThis research explores the relationships between the representation of digital models and mobility flows related to a coastal territory. The aim is creating a synergy between travel data and their representation, in order to optimize the territorial development strategies of soft mobility. A combination of GIS and Computational design digital tools has been used to achieve this goal. The case study selected is the set of municipalities on the Abruzzo coast, ranging north to south from the territory of Ortona to San Salvo. The choice of a case study limited to the coast was determined by the need to make different flows coexist between the summer and winter seasons. In the analysed territorial ecosystem, a useful strategy was developed to integrate private transport with an apparatus that facilitates soft mobility. To this purpose, seasonally adjusted isochrones were developed from the urban centres of the eight municipalities considered. The calibration of the isochrone was elaborated (Schantz and others, 2017) by calculating an area reachable by bike with a travel time of 25 minutes. The overlap between the isochrone of contiguous municipalities provides information about the areas where the cycling network needs to be implemented in intra-municipal and inter-municipal mobility. Finally, the studies carried out show that these overlapping areas are not localised as would be conceivable on administrative borders
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
