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
The Planning of DOW Pipeline Reconstruction near the Estuary Areas of Chi-Ben River in Taitung County of Taiwan
No full textThe purpose of this presentation is to
discuss the planning and relevant engineering
issues relating to the reconstruction of a deep
ocean water (DOW) pipeline near the estuary
areas of the Chi-Ben River in Taitung County
of Taiwan. In 2012, the DOW pipeline
constructed for the Eastern Taiwan Deep Sea
Water Innovation & Research Center (ETDIC)
collapsed after typhoon activity and has been
unable to supply DOW since then, resulting in
severe adverse effects to DOW industrial
development in Eastern Taiwan. Due to the
fact that ETDIC had been established and
operated since 2009 by the Ministry of
Economic Affairs (MOEA), and had played an
important role for DOW development, MOEA
has decided to reconstruct the pipeline. Currently, planning and execution are
underway.
After a thorough investigation by the use of
underwater acoustic instruments including
side-scan sonar and the multi-beam system
(shown in Figure 1) and/or remotely-operated
vehicle (ROV), it has been concluded that the
failure of the DOW pipeline was caused by the
following two factors:
1. Environmental Factors: the large amount
of sand and silt carried by the Chi-Ben River
after the typhoon rain may have resulted in a
large deposit and sediment movement beyond
the safety factor set by the design limits.
2. Design and Construction Factors: ROV
images have shown that the connectors
between pipelines were displaced, and the
pipelines themselves were too far away from
the planned route, indicating that the
techniques on pipeline connectors and
positioning of pipeline laying are very
important.
In view of aforementioned problems, the
new project has been proposed as follows:
1. In response to the environmental factor,
two new routes, route A and B, are under
investigation and planning (Figure 2). Route A
is about 1.5-2.5 km away from the south of the
Chi-Ben River mouth, and the seabed slope is
relatively smooth and stable in comparison
with all five routes surveyed. The seabed
consists mostly of pebbles. The other
alternative route B under consideration is
about 2.5-3.2 km south of the Chi-Ben River
mouth. In addition, there are many factors that
need to be considered.
2. In response to the pipeline design and
construction method problems, it is necessary
to carefully choose the materials used for the
pipeline construction, e.g., HDPE with pull
strength higher than 230 kg/m2 and bend
strength of 350 kg/m2. The approaches employed for laying down the pipeline and the positioning of the pipeline are of utmost importance.補正完
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
