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
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

No full textPurpose/Background: managing grade iii/iV hemor- rhoidal disease with traditional excisional surgery or stapled hemorrhoidopexy have been challenging undertak- ings considering the risks of non-negligible complications associated with invasive techniques. the aim of this study was to assess the safety and efficacy of mucopexy-recto Anal Lifting (murAL) in treating patients affected by grade iii and iV hemorrhoidal disease.
Methods/Interventions: three hundred eighty-six patients affected by grade iii and iV hemorrhoidal diseasehave been enrolled in our study and underwent mucopexy- recto Anal Lifting (murAL) between may 2013 and November 2018. the method has already been described in detail by Pagano et al. [minerva chirurgica 2018 october; 73(5):469-74]. Arterial ligation and mucopexy involving progressive lifting have been performed at 6 positions, by following a standardized sequence (as outlined in the attached image). six longitudinal scars anchor perma- nently the mucosa and sub-mucosa to the muscular wall beneath. the follow-up examinations have been carried out by independent observers as follows: a digital explora- tion 3 weeks after the intervention, digital exploration and proctoscopy at 3 and 12 months, repeated at a 12-month interval. Patients not following strictly the postoperative clinical examination calendar have been excluded from the study. Primary outcome measure was the recurrence rate observed in patients who completed at least 12 months of follow-up. secondary outcome measures were: operative time, postoperative hospital stay, postoperative pain, post- operative symptoms and patient satisfaction score.Results/Outcome(s): murAL has been performed on 386 patients (59.6 % male, mean age 53.9, range 26-87); 297 (76.9%) with grade iii and 89 with grade iV hemor- rhoids. thirty-three (8.5%) patients had murAL as a revisional procedure of a previous intervention (17 stapled anopexy, 6 milligan-morgan, 5 murAL, 3 stArr, 2 tHd). mean duration of follow-up was 814 days (range 15-2007). the mean duration of the procedure was 23 minutes (range 13-45); 195 patients (53.0%) were discharged on the day of surgery and 163 (44.3%) had a one-day hospitalization; 10 patients treated with murAL required hospitalization > 1 day due to comorbidity. Pain Nrs score (0-10) on the first, second and third postoperative day was 3.8, 2.5 and 2.2 respectively. No major complications were observed. thirty-eight (10.3%) patients, all submitted to spinal anesthesia, had postop- erative acute urinary retention. transient fecal urgency was observed in 13 (3.4%) patients at the first follow-up. mean time to return to normal activity was 7 days (range 2-10). At one-year follow-up 89.5% of patients reported an excellent/good satisfaction score. operating time wassignificantly shorter, postoperative pain lower and tran- sient fecal urgency less frequent in patients with grade iii than in those with grade iV hemorrhoids. one-year recur- rence rate was evaluated in 279/386 patients (214 with grade iii and 65 with grade iV disease). recurrence was observed in 12 patients (4.3%): 7/214 (3.3%) with grade iii and 5/65 (7.7%) with grade iV hemorrhoids (P=0.12). two patients out of 28 (7.1%) had a second recurrence after murAL (1 previous mm, and 1 previous murAL).
Conclusions/Discussion: in our experience, mucopexy- recto Anal Lifting (murAL) with its standardized proce- dure management approach, offers a safe and effective treatment solution of managing grade iii and iV symp- tomatic hemorrhoids with minimal invasivity, lowering the patient’s risk of developing severe complications. the method does not cause tissue trauma, which permits to easily perform a redo-murAL in the event of recurrence
