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
Exploring adaptability in long-distance runners: effect of foot strike pattern on lower limb neuro-muscular-skeletal capacity
No full textThis thesis is an exploration of the controversial hypothesis that a runner’s foot strike
pattern defines the demands on the lower extremity, and hence we expect to observe
adaptations to its anatomical, mechanical, and neurological function.
First, we review the state of the literature to find that long-distance running seems to
have an osteogenic and myogenic effect on the foot; however, studies often do not
control for foot strike or footwear worn, leading to circumstantial evidence. We
therefore aim to determine structural differences between two groups of runners with
an antithetical foot strike pattern (habitual rearfoot versus habitual forefoot strikers).
We find groups to have similar foot muscle size and to have similar toe flexor strength.
Further, we find the trabecular bone volume to be larger in the first metatarsal bone in
forefoot strikers; however, the calcaneus reveals no differences between groups in
bone density or trabecular structure.
We then explore the function of the ankle, in isolation and in coordination with the
knee and hip. It appears that habitual forefoot strikers may have access to a wider
physiological range of ankle torque and ankle joint angle. This increased potential may
allow forefoot strikers to adapt to different footwear by regulating ankle stiffness
depending upon motor task. The inter-joint coupling investigation reveals knee-hip
coordination pattern of runners to be the most consistent, while ankle-knee couple was
the most variable. Forefoot strikers have more variable coordinative patterns than
rearfoot strikers irrespective of the footwear worn.
We then asked a neuro-mechanical question: Is the control of running kinematics and
kinetics influenced by the foot strike type? Using analysis of persistence in time series\ud
and analysis of motor redundancy in human movement, we show that rearfoot strikers
employ higher active control over critical variables such as limb posture at initial
ground contact and leg stiffness. The results suggest that forefoot strikers achieve
control of these parameters through exploitation of the abundant degrees of freedom
available in the system.
Finally, we conclude the thesis with indications for short-term objectives in-line with
the research that begun in this thesis
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
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
