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
Āsana for Back, Hips and Legs to Prevent Musculoskeletal Disorders among Dental Professionals: In-Office Yóga Protocol
Full text linkAbstract: Dental professionals are exposed to significant unavoidable physical stress, and theoretical
ergonomic recommendations for a sitting workplace are inapplicable in many dental activities.
Work-related musculoskeletal disorders (WMSDs) represent a serious health problem among dental
professionals (prevalence: 64–93%), showing involvement of 34–60% for the low back and 15–25%
for the hips. Muscle stress; prolonged sitting; forward bending and twisting of the torso and
head; unbalanced working postures with asymmetrical weight on the hips and uneven shoulders;
and others are inevitable for dental professionals. Therefore, the approach for the prevention and
treatment of WMSDs must be therapeutic and compensatory. This project was conceived to provide
a Yoga protocol for dental professionals to prevent or treat WMSDs from a preventive medicine
perspective, and it would represent a Yoga-based guideline for the self-cure and prevention of
musculoskeletal problems. Methods: Specific Yoga positions ( ̄asana, such as Vir ̄asana, Virabhadr ̄asana,
Garud ̄asana, Utkat ̄asana, Trikon ̄asana, Anuvitt ̄asana, Chakr ̄asana, Uttan ̄asana, Pashimottan ̄asana) have
been selected, elaborated on and adapted to be practiced in a dental office using a dental stool or the
dental office walls or a dental unit chair. The protocol is specifically devised for dental professionals
(dentists, dental hygienists and dental assistants) and targeted for the low back, hips and legs
(including knees and ankles). The protocol includes Visranta Karaka Sthiti (supported positions)
in sitting (Upavistha Sthiti) and standing (Utthistha Sthiti) positions, twisting/torsions (Parivrtta),
flexions/forward bend positions (Pashima) and extensions/arching (Purva) for musculo-articular
system decompression and mobilization. Results: Over 60 Yog ̄asana—specifically ideated for back
detensioning and mobilization, lumbar lordosis restoration, trunk side elongation, hip release and leg
stretches and decontraction—are shown and described. The paper provides a meticulous description
for each position, including the detailed movement, recommendations and mistakes to avoid, and
the breathing pattern (breath control) in all the breath-driven movements ( ̄asana in viny ̄asa). An
exhaustive analysis of posture-related disorders affecting the lower body among dental professionals
is reported, including low-back pain, hip pain and disorders, piriformis syndrome and quadratus
femoris dysfunction (gluteal pain), iliopsoas syndrome, multifidus disorders, femoroacetabular and
ischiofemoral impingement, spinopelvic mobility, lumbopelvic rhythm, impairment syndromes,
lower crossed syndrome, leg pain, knee pain and ankle disorders. Conclusions: A detailed guideline
of ̄asana for low-back decompression, hip joint destress, piriformis and gluteal muscle release, lumbar
lordosis recovery and a spinopelvic mobility increase has been elaborated on. The designed Yog ̄asana
protocol represents a powerful tool for dental professional
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
