Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Pioneering role of IRIS in the resurgence of Small Modular Reactors
No full textThis paper presents an overview of the first 10 years
of the IRIS project, summarizing its main technical
achievements and evaluating its impact on the resurgence
of small modular reactors (SMRs). SMRs have
been recurrently studied in the past, from early days of
nuclear power, but have never gained sufficient traction
to reach commercialization. This situation persisted also
in the 1990s; the focus was on large reactors based on
the presumed common wisdom of this being the only way
to make the nuclear power plants competitive. IRIS is
one of several small reactor concepts that originated in
the late 1990s. However, the specific role and significance
of IRIS is that it systematically pursued resolving
technology gaps, addressing safety, licensing, and deployment
issues and performing credible economics analyses,
which ultimately made it possible—together with
other SMR projects—to cross the “skepticism threshold” and led the making of a convincing case—domestically
and internationally—for the role and viability of smaller
reactors. Technologically, IRIS is associated with a number
of novel design features that it either introduced or
pursued more systematically than its predecessors and
ultimately brought them to a new technical level. Some of
these are discussed in this paper, such as the IRIS Safetyby-
Design, security by design, the innovative thermodynamic
coupling of its vessel and containment, systematic
probabilistic risk assessment–guided design, approach
to seismic design, approach to reduce the emergency
planning zone to the site boundary, active involvement of
academia, and so on. Many individuals and organizations
contributed to that work, too many to list individually,
and this paper attempts to pay tribute at least to
their collective work
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
