Analysis of Fuzzyness in Spatial Variation of Real Estate Market: Some Italian Case Studies
No full textThe paper shows a method aiming at giving a measure of fuzzyness referring to the change of real estate value from an area to another one belonging to the same urban context. This measure is based on Munda’s “Semantic distance” (1997). Such measure is considered helpful to validate the traditional subdivision of the city by the Italian Cadastral System in the so-called "cadastral census section". The paper starts explaining the cadastral approach that guides the partition of an urban area, according to the hypothesis of homogeneity of the real estate values and of the physical context. After the explanation of the partition of Italian Cadastre, the concept of semantic distance is introduced, as measure of the difference among estate values referring to the cadastral sections, that in this case are considered as well fuzzy variables. The semantic distance is compared with the expected real estate value; starting from such comparison it is possible to estimate a degree of uncertainty in the variation of values area by area of the urban context.
The case studies refer to the biggest Southern Italian metropolitan areas, Naples, Bari and Palermo. The work is due to a joint effort. In detail, C. Mariano wrote the first paragraph and C.M. Torre the second the third and the fourth paragraph
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
Zero–Energy Living Lab
No full textIn order to reduce the existing gap between design and as-built building performance, experimental data are required, both for single components and for whole building characterization. Real scale buildings, designed and equipped to perform such as living laboratories, may allow testing the effectiveness of different technologies to reduce the energy consumption and/or to increase the indoor environmental quality of the building as a whole. In order to understand to what extent the nearly zero-energy and the Passivhaus concepts could be extended to the Mediterranean climate, a new building (a detached single family house) was designed and constructed in the municipality of Mascalucia (Catania), in the Italian region of Sicily. It has been conceived to perform such as a living laboratory able to provide useful information on the actual performance of the building and its components, such as the Air to Earth Heat Exchanger. The design process was led by an optimization procedure based on extensive energy simulations. It resulted in an optimal energy balance and favourable thermal comfort conditions along the year. The building is equipped with an accurate Building Automation and Control System (BACS), and a number of sensors for a detailed energy and environmental monitoring. The early monitored data, following the commissioning phase, provide a first insight of the energy and comfort performance of the building. Further results including improvements in control algorithms and a comprehensive data analysis are ongoing and their completion is expected in a short time
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
