Progress on the implementation of Energy Performance Certificates in EU
Full text linkEnergy performance certificates (EPCs) are a key policy tool to inform about and to foster improvements to the energy performance of the building stock. Since their introduction in 2002 by the Energy Performance of Buildings Directive (EPBD), EPCs have been implemented across Member States (MSs) in different ways, depending on the political and legal context, the available technical capacities, as well as the characteristics of the buildings stock and buildings market in general.
In 2021, in the context of ?Fit for 55? legislative package, the European Commission proposed the third revision of the EPBD. The proposal improves the provisions on EPCs, their issuing and display, and their databases. In particular, it pursues harmonisation across MSs through a mandatory template for EPCs and a harmonised scale of energy performance classes.
This report presents the results of a survey conducted by JRC among MSs to collect information on how each MS has implemented the EPC scheme. It highlights differences among MSs regarding the energy uses included in the calculation, the floor area considered, the definition of energy classes, the main indicator(s), the number of EPCs issued, the availability of a national register, the mechanisms in place to ensure the quality of EPCs
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 white marble of the cloister of the Real College-Seminar of Corpus Christi in Valencia (Spain): archival researches for de identification of its provenance and diagnostic studies for understanding its decay
No full textWhite marble and Ribarroja stone are the stone materials employed for the columns, the balustrade and the façades of the cloister of the Real Colegio Seminario of Corpus Christi in Valencia (1586-1611) also called Colegio del Patriarca. The state of conservation of the marble elements of the balustrade is more critical than that of the columns. The lack of data concerning the type and provenance of the marble from both the balustrade and the columns and its chemical-physical characteristics, has probably been the cause of wrong interpretations and wrong choices adopted in the restoration works executed in the 1980s. The data reported in this paper are the preliminary results of an interdisciplinary study based on the analysis of the archival sources and on the diagnostic investigations performed on the constituent materials. The gathered data allowed us to define the provenance of the marble (Carrara, Italy) and to establish the main causes of decay of the elements of the cloister
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
