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
Safety and Efficacy of the Use of Supraglottic Airway Devices in Children and Adolescents Undergoing Adenotonsillectomy—A Systematic Review and Meta-Analysis
No full text(1) Background: Supraglottic airway devices (SAD) have been used in children and adolescents undergoing adenotonsillectomies under general anesthesia. This systematic review and meta-analysis investigate the safety and efficacy of using SADs when compared to an endotracheal tube (ETT). (2) Methods: After registering with PROSPERO, databases like PubMed, Scopus, OviD, CINAHL, and Cochrane Library were searched using relevant keywords from the year 2000. We used RoB-2 for risk-of-bias assessment, GRADE for assessing the quality of evidence, RevMan 5.2 for qualitative meta-analysis, and trial sequential analysis (TSA) to corroborate the significant findings of meta-analysis. (3) Results: Out of 200 studies, 5 randomized-controlled trials fulfilled inclusion criteria. The quality of evidence was moderate for laryngospasm, low for airway device failure, and very low for recovery time. The incidence of laryngospasm was comparable between SADs and ETT (RR: 0.80, 95% CI-0.36, 1.80, p = 0.59). The incidence of airway device failure was significantly higher with SADs than ETT (RR: 11.29, 95% CI: 2.73, 46.66, p = 0.0008). The postoperative recovery time was significantly less with SADs than with ETT use (MD: −4.33, 95% CI: −5.28, −3.39, p < 0.0001), which was confirmed by the TSA. (4) Conclusions: The results of this review suggests that use of SADs can provide a lesser postoperative recovery time and comparable incidence of laryngospasm, with a higher incidence of failure of SAD when compared to ETT. Use of SAD for pediatric and adolescent adenotonsillectomies should be individualized based on patient characteristics, and on the expertise of the anesthesiologist and the surgeons involved
Comparison of the Two Different Formulations of Propofol I.E. Propofol 1% (Long Chain Triglyceride) With Propofol Lipuro 1% (Medium Chain Triglyceride +Long Chain Triglyceride) As an Induction Agent for Elective Short Surgical Procedures: A Study from Ter
Get PDFIntroduction: The rapid return of psychomotor functions has made propofol an anaesthetic agent of choice for day care surgeries. The more rapid return of consciousness with minimal residual central nervous system effects is one of the most important advantages of propofol compared with alternative drugs administered for the same purpose. The context-sensitivity half time of propofol is very short even with prolonged periods of infusion combined with short effect site equilibration time, which makes this drug an intravenous agent of choice for maintenance of anaesthesia and for intravenous sedation.
Objective: To compare the two different formulations of Propofol i.e. Propofol 1% (long chain triglyceride) with Propofol lipuro 1% (medium chain triglyceride +long chain triglyceride) as an induction agent for elective short surgical procedures.
Results: 62.0% of patients have pain on injection with standard Propofol while 38.0% of patients have pain on injection with Propofol lipuro. By applying chi-square test p value was 0.01 which was statistically significant. Total dose for induction in standard Propofol group was 123.60±20.678 (MEAN±SD) and in Propofol lipuro group was 120.00±14.142 (MEAN±SD) sec. It was not statistically significant.
Conclusion: In this study on hundred healthy subjects, we found that, the new formulation of Propofol (Propofol lipuro 1%- medium chain triglyceride + long chain triglyceride) was well tolerated and generally indistinguishable from standard Propofol 1% (long chain triglyceride). However, we did find a significant decrease in the incidence of pain on injection with new formulation of Propofol.
Conclusion: Propofol 1% (long chain triglyceride) with Propofol lipuro 1% (medium chain triglyceride +long chain triglyceride), elective short surgical procedure
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
