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
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
Multi-storey Building Retrofit by ADAS-Equipped Braces
No full textAn alternative passive energy-based retrofit design is proposed for a reinforced concrete building, seismically retrofitted in 2013 and damaged by the 2016 Central Italy earthquake. An evaluation analysis carried out by referring to the pre-2013 conditions shows unsafe stress states in most structural members and severe damage in the masonry partitions and perimeter infills. The alternative retrofit strategy of the building, which consists in the incorporation of a dissipative bracing system equipped with pressurized fluid viscous spring-dampers, allows attaining a substantial seismic performance improvement. This is assessed by a safe response of all columns and beams, and at most a very slight damage in the masonry panels, in post-intervention conditions
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
Multi-storey Building Retrofit by ADAS- Equipped Braces
Full text linkIncorporation of dissipative bracing systems is an emerging seismic retrofit strategy for frame structures. Among the
several types of devices currently adopted as passive protection elements, Added Damping and Stiffness (ADAS) steel
dissipaters have a well-established tradition. This is a consequence of their plain working principle, based on the
elastic-plastic behaviour of the constituting plates, as well as of their relatively easy installation. In spite of this, the
design of ADAS dampers is not simple, because it requires a proper balance between the addition of energy dissipation
and horizontal translational stiffness. An energy-based design criterion is formulated to this aim in this study, which
directly relates the total number of plates of the dissipaters to the supplemental damping energy needed to jointly
reduce stress states and storey drifts, expressly taking into account the reduction of the fundamental vibration period
due to the stiffening effect of the bracing system. A seismic retrofit intervention is demonstratively designed by
applying this criterion for a 6-storey building with reinforced concrete structure, an assessment analysis of which
shows poor seismic performance capacities. A comparative analysis among three different installation hypotheses of
the ADAS devices allows to select the distribution capable of attaining the best performance of the retrofit measure
