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
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
Long waves in and near the surf zone.
Full text linkFour sets of field measurements were made of swell In and just seaward
of the surf zone off a uniform sandy beach. Power spectra computed
for both the pre-breakers and the foam lines revealed long waves associated
with the swell having peak periods centered at approximately 80
seconds. Long wave records were produced by filtering out the ordinary
swell through computing running means of the pre-breaker and foam- line
records. Computer comparison of the long-wave records at the offshore
and surf-zone sites for a given field run resulted in a time-correlation
curve for various time lags between the records. Curves for all of the
runs reveal that the long waves arrive from the open ocean, probably as
forced waves travelling with swell groups, undergo reflection at the
beach, and return back to sea as free waves.Lieutenant, United States Navyhttp://archive.org/details/longwavesinndnea109451256
Field observations of wave runup on a sand beach.
Full text linkSix sets of field measurements of runup resulting from both wind
waves and swell were made on a uniform sand beach. Waves were recorded
simultaneously directly offshore at a point outside the surf zone. Each
individual runup was correlated with a specific wave, using a traveltime
plot. Runup occurrences were always found to be fewer in number
than wave occurrences, particularly when wind waves were present. Large
variations in the runup resulting from waves of a given height were
found to exist. These variations in height and ratio of runup to waves
were caused in large part by the interaction of successive foam lines.
Interaction occurred in the form of retardation by backwash of preceding
waves, overtaking by a following foam line, and overriding by a small
unbroken wave. It is concluded that the complicated nature of runup resulting
from ordinary sea and swell makes it difficult to predict runup
accurately from laboratory studies.Lieutenant, United States Navyhttp://archive.org/details/fieldobservation109451220
