Economics for sustainability: Impacts on the Real Estate Appraisal and Economic Evaluation of Projects
Full text linkThe aim of this piece of work is to present the recent developments of the discipline of Real Estate Appraisal and Economic Evaluation of Projects in relation to Sustainable Architecture and its design. The focus is on the principles borrowed from economics and, in particular, on the transition from a linear to a circular thinking and the related impacts on estimative theories and practices. Starting from the urgency of the underlying problems, Life Cycle Thinking is recalled within which the theories of the Green Economy, the Circular Economy and, recently, the Helical Economy are developed. The reasoning then recalls some passages of disciplinary evolution to include the public, environmental and social dimension. A methodological survey follows with attention to the recent – and now almost consolidated – approaches for projects evaluation and market analysis, attributable to international energy-environmental policies. In terms of the evaluation of new construction projects or retrofitting existing assets, the transition from the financial perspective, in terms of Linear Economy, to the perspective of economic-energy-environmental sustainability, from a Circular Economy perspective, is a central point. From the point of view of market analysis, the importance of exploring the impact of sustainable architecture on the values and dynamics of supply and demand is underlined. The results of the work show that the use of life cycle valuation is essential for the reuse of resources, but also for the containment of their consumption in the production phase. The use of tools capable of jointly analyzing energy and costs could guide decision-making processes between different design options, encouraging conversion and efficiency strategies, even in contexts of weak sustainability

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
[Evaluation of body composition in obese subjects].
No full textThe body composition of 12 obese patients was assessed. The dilution method was
used to assess the total areas of sodium and water. Total potassium was measured
indirectly using the following formula: total potassium = R X total body
water-total body sodium, where R represents the contents in a whole blood sample.
Both fat and muscle mass were found to be increased in the obese subjects.
Examination of the total sodium/total water ratio and the relationship between
weight and muscle mass, cellular mass and total fat showed the dimensional
increase was harmonious
