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 Link Between Roll and Steering Torque in Motorcycles
No full textSteering torque is the most important control input
for motorcycle turning; however, some riders believe they can
steer using upper body roll alone. As other investigations have
shown rider roll to be an ineffective for path control, there
is likely a link between rider roll and steering torque in
motorcycles. This paper examines new results, looking at the
relationship between roll and steering. The specific results look
at the connection in two directions. First, results examine how
steering torque is generated due to motorcycle roll. Secondly,
the rider’s roll and yaw response to steering motion is presented.
The results show strong links between motorcycle roll rate and
steering, as well as steering and rider motion. The link between
steering and rider roll implies the rider can generate steering
torque by leaning their upper body. As the generated forces and
motions are non-negligible they need to be investigated further.
This information, is being used to develop a new model of the
rider’s passive impedance. In turn this model can be used to
ensure the stability of motorcycles, regardless of the rider
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
A new test rig for motorcycle rider impedance measurement
No full textThere are many factors affecting motorcycle stability, with the rider remaining a significant unknown. Here we show the University of Southampton’s motorcycle shaker rig, a new piece of equipment to take rider impedance measurements. This rig improves on previous investigations, by taking 10 force and moment measurements, as well as using up to six IMUs. This new rig also allows the effect of posture to be investigated for the first time. As posture has a significant effect on human response to vibration, and there is a large difference in posture between motorcycle styles, this a key investigation for motorcycle stability. The rig’s overall design is presented first, then a closer look at the ergonomics, and an explanation of the instrumentation system. Finally, preliminary results are presented, to show the capabilities of this rig and instrumentation system
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
