Field monitoring in Mediterranean climate to quantify thermal performances of vertical greening systems
No full textGreen envelopes can provide environmental and ecological benefits in dense urban areas, improving air quality, mitigating Urban Heat Island effect, reducing energy use for air conditioning. The present study is based on field monitoring of the pilot project INPS Green Façade, built in Genoa (Italy) to quantify its environmental, economic, and social benefits. The vertical greening system was installed on the south wall of an office building built early in the last century and renovated in the 1980’s, owned by INPS (National Institute of Social Insurance). The facade is exposed to solar radiation several hr/day in summer and 1–2 hr/day during winter. The external walls are constituted by two layers of masonry spaced by a 51 cm air gap (resulting from the retrofitting works), with a layer of 5 cm of insulating material. An experimental investigation allows evaluating the thermal performances of a well vegetated vertical greening system during summer and winter. This study demonstrates that a green layer can mitigate outdoor and surface temperatures, thus improve conform conditions and reduce building surfaces warming up (contributing to urban heat island mitigation). The cooling capacity of vertical greening systems, with air temperature difference up to 10°C, can be exploited to reduce energy demand for air conditioning during summer. Although the energy saving for cooling strongly depends on several factors, the results obtained show a potential significant reduction of energy need for air cooling. The consequence of the vertical greening system on energy demand during winter is more complex to define because combined effects can be registered: prevention from solar radiation, shielding from the wind and a natural ventilation of the cavity
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
The use of vertical greening systems to reduce the energy demand for air conditioning. Field monitoring in Mediterranean climate
No full textGreen envelopes can provide environmental and ecological benefits in dense urban areas, improving air quality, mitigating Urban Heat Island effect, reducing energy use for air conditioning. The aim of the research presented is to determine the performance of vertical greening systems in the Mediterranean climate of Italy, analyzing a pilot project built in the city of Genoa. The authors performed an experimental investigation to evaluate the cooling potential of a well vegetated vertical greening system during summer. Field monitoring of the pilot project INPS (National Institute of Social Insurance) Green Façade, installed in 2014 on the south wall of an office building built early in the last century and renovated in the 1980’s, demonstrates that a green layer can mitigate outdoor and surface temperatures, thus improve conform conditions and reduce building surfaces warming up (contributing to urban heat island mitigation). The cooling capacity of vertical greening systems can be exploited to reduce energy demand for air conditioning (with a theoretical energy saving potential of 26% for summer season). Although the energy saving for cooling strongly depends on several factors, the results obtained show a potential significant reduction of energy need for air conditioning
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
