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
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
To Suction or Not To Suction That is the question. Studies of endotracheal suction in post-operative cardiac patients
No full textBackground
Globally, cardiovascular disease is the leading cause of death with an estimated 17.9 million deaths
worldwide. Cardiac surgery is widely performed, with post-operative care often including admission to
an intensive care unit and a period of planned mechanical ventilation. Airway management includes
endotracheal suction, which is known to have deleterious effects. This body of work investigates
endotracheal suction in uncomplicated cardiac surgical patients.
Aim
The overarching aim of this thesis was to assess the safety of actively avoiding endotracheal suction in
post-operative cardiac surgical patients ventilated for less than 12 hours. Additional aims included
reviewing what evidence was available about avoidance of endotracheal suction in the adult intensive
care unit patient population; describe local endotracheal suction practice, and elucidate the patient
experience of the endotracheal tube and endotracheal suction.
Methods included:
• A systematic review investigating the evidence for the avoidance of endotracheal suction in the
adult intensive care population.
• An observational audit describing endotracheal suction practice within the cardiothoracic and
vascular intensive care unit in Auckland City Hospital.
• A point prevalence observational study describing suction practice across intensive care units in
New Zealand and Australia.
• A qualitative study to elucidate the patient experience of the endotracheal tube and endotracheal
suction.
• A prospective, non-inferiority, randomised controlled trial investigating the safety of avoiding
endotracheal suction.
Results
The systematic review showed an absence of evidence regarding the avoidance of endotracheal suction.
Both the observational and studies identified discrepancies between clinical guideline recommendations
and clinical practice.
The qualitative study found that half the participants recalled the endotracheal tube, although none
recalled suction. Participants provided descriptions about emerging from the fog of sedation,
hallucinations and early post-operative recovery.
The randomised controlled trial demonstrated that endotracheal suction could safely be avoided in a
patient cohort having cardiac surgery, with no increase in complications of extubation or escalation of
oxygen therapy.
Conclusions
This body of work adds to the evidence about endotracheal suction; provides the first evidence about
avoidance of endotracheal suction; describes the patient experience of the endotracheal tube and early
post-operative recovery. These findings can be used to inform clinical practice and nurse education and
training
