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
The prognostic significance of atrial arrhytmias recorded early after cardioversion for atrial fibrillation
No full textBackground Atrial fibrillation (AF) has a high risk of recurrence after electrical cardioversion (CV)The purpose of our study was to investigate prognostic factors, such as heart rate (HR) and atnalarrhythmias, measured during Holter recording for 24 hours after CVMethods We prospectively studied 117 consecutive patients (pts) (mean age±S D 61 6 ±10,8 years)subjected to CV, who successfully converted to sinus rhythm All underwent echocardiography and 24hour Holter after CV The majority of pts (60,7%) folio wed-up for one yearResults Thirty-seven pts (31 6%) recurred to AF during the first year of follow-up (group I) Thirty-fourpts (29 1%) remained in sinus rhythm at one year (group II) During one month of follow-up, 22 pts(18,8%) recurred to AF (group III) and the rest remained in sinus rhythm (group IV) Age, gender,underlying disease, left atrium size, fractional shortening, duration of AF and the medication taken weresimilar between the two groups (All P-values=NS) Group I had more atrial premature complexes perhour (APC/h) compared with group II and more APC/h in the first and second six-hour segment of theHolter (P10 APC/h hadhigh specificity but low sensitivity (91 2% και 32 4% respectively) Group III had more atnal prematurecomplexes per hour (APC/h) compared with pts of group IV and more APC/h in the first and second sixhoursegment of the Holter (P=0 002, P=0 057 and P=0 013, respectively) Cut-off analysis showed thatpts with more than 32 APC/h had 10 times higher risk of AF recurrence (OR=10 4 with 95% C 1=2 3-47 4) (sensitivity=75% specificity=77%) Group III pts had higher maximum, average and minimumheart rate compared to group IV (P=0 0013, P=0 0221 and P=0 0331, respectively) Cut-off analysisrevealed that pts with maximum heart rate (Max HR) more than 90 5 bpm had 6 7 times higher risk of AFrecurrence (OR=6 68 with 95% C 1=1 3-34 9) (sensitivity=69% specrficity=78%) Pts with combinationof Max HR more than 90 5 bpm and more than 32 APC/h had 25 2 times higher risk of AF relapse(OR=25 2 with 95% C 1=1 8-352 5)Conclusions Simple 24hour Holter may help to identify pts at higher risk of AF recurrence after CV.Σκοπός Μελετήσαμε την προγνωστική άξια των κολπικών αρρυθμιών και της καρδιακήςσυχνότητας, που καταγράφονται με ενα Holter 24ωρης καταγραφής αμέσως μετά απο επιτυχήηλεκτρική καρδιοαναταξη, ως προς την υποτροπή της αρρυθμίαςΜέθοδοι Μελετήσαμε 117 διαδοχικούς ασθενείς (μέση ηλικία ± SD 61,6±10,8 ετη, 53,8%άνδρες), οι οποίοι υπεβλήθησαν σε επιτυχή ηλεκτρική καρδιοαναταξη για KM Σε όλους τουςασθενείς τοποθετήθηκε Holter 24ωρης καταγραφής μετά απο την ηλεκτρική καρδιοαναταξη Το60,7% των ασθενών παρακολουθήθηκε για ενα έτος Οι υπόλοιποι ασθενείς παρακολουθήθηκανγια ενα μήναΑποτελέσματα Τριαντα-επτα (31,6%) ασθενείς υποτροπίασαν σε KM κατά τη διάρκεια τουπρώτου έτους παρακολούθησης (ομάδα Ι) Τριαντα-τεσσερις ασθενείς (29,1%) παρέμειναν σεφλεβοκομβικο ρυθμό το πρώτο έτος (ομάδα Π) Εικοσι-δυο ασθενείς (18,8%) υποτροπίασαν σεKM κατά τη διάρκεια του πρώτου μήνα παρακολούθησης (ομάδα III) Οι υπόλοιποι ασθενείςπαρέμειναν σε φλεβοκομβικο ρυθμό τον πρώτο μήνα (ομάδα IV) Οι ασθενείς της ομάδας Ισυγκρινόμενη με την ομάδα II είχαν μεγαλύτερο αριθμό έκτακτων κολπικών συστολών ανα ωρα(APC/h) για το σύνολο της καταγραφής Holter, για το πρώτο εξάωρο και για το δεύτερο εξάωρο(Ρ10 APC/h και η παρουσία SVT είχε υψηλήειδικότητα άλλα χαμηλή ευαισθησία (91,2% και 32,4% αντίστοιχα) Οι ασθενείς της ομάδας IIIσυγκρινόμενη με την ομάδα IV είχαν μεγαλύτερο αριθμό APC/h για το σύνολο της καταγραφήςHolter, για το πρώτο εξάωρο και για το δεύτερο εξάωρο (Ρ=0,002, Ρ=0,057 και Ρ=0,013,αντίστοιχα) Οι ασθενείς της ομάδας III συγκρινόμενη με την ομάδα IV είχαν μεγαλύτερη μέγιστη(max HR), μέση και ελάχιστη καρδιακή συχνότητα (Ρ=0,0013 Ρ=0 0221 και Ρ=0 0331αντίστοιχα) Οι ασθενείς με max HR>90,5 bpm είχαν 6,6 μεγαλύτερο κίνδυνο υποτροπής της KM(OR=6,68 με 95% CI 1 3-34,9) τον πρώτο μήνα (ευαισθησια=69%, ειδικοτητα=78%) Οσυνδυασμός max HR>90,5 bpm και >32 APC/h είχε 25,2 μεγαλύτερη πιθανότητα υποτροπής τηςKM τον πρώτο μήνα (OR=25,2 με 95% C Ι 1,8-352,5)Συμπεράσματα Με ενα απλό Holter 24ωρου μπορούμε να αναγνωρίσουμε ασθενείς με υψηλόκίνδυνο υποτροπής της κολπικής μαρμαρυγής μετά απο την ηλεκτρική καρδιοαναταξη

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
