Comparison of numerical and experimental performances of nZEB residential building in Putignano (Apulia Region)
Full text linkThe sustainability of the European Regions, in terms of society and economy and environment, is strongly based on renewable energy and resource efficiency. This implies the large scale deployment of nearly Zero – Energy Buildings (nZEBs). As well as the technology is already available and proven. However the diffusion of nZEB in Mediterranean areas is a challenge for the local market actors considering the short time. In this direction our research is oriented, proposing the case study of the first passive building in Putignano (Apulia). The goal is to observe the impact of the comfort setting on energy demand during the everyday life. This new approach aims at simultaneously considering both the energy performance and the comfort and health of the inhabitants. The case study includes the simulation model and the measuring campaign. It aims to verify if occupants of nZEB will be aware of the qualities of their home and learn to manage and monitor energy consumption independently. The concept is to observe the impact of comfort setting on energy demand during the everyday life in heating season of the passivhaus tenants
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
[Use of tobacco smoke: approach and risk perception by middle-school students in Catania (Italy)]
No full textThe aim of this study was to investigate the approach and behaviour of middle school students in Catania, towards the risks associated with tobacco smoke. This study is part of a multicentric project evaluating the lifestyles of middle school students (grades 6-8), carried out by the Research and Health Education Group (GRES) and was performed during the 2006/2007 school year. In total 432 students participated in the study by completing a self-administered questionnaire. Data was analysed by using the Statistical Package for the Social Sciences (SPSS). Results show an increasing trend in the number of smokers from grades 6 to 8. In grades 6 and 8 most smokers are female while in grade 7 male smokers outnumber female smokers. Three percent of the student population reports smoking occasionally and 3% are regular smokers. In light of these results families, schools and institutions should take charge of programming and implementing health promotion interventions aimed at reducing risks and improving the quality of life of students in Catania
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
