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
Female sexual dysfunction in urogenital prolapse surgery: colposacropexy vs. hysterocolposacropexy
No full textIntroduction. Colposacropexy (CSP), with or without hysterectomy, is a valid technique for the repair of severe urogenital prolapse. For many years, uterine prolapse has represented an indication for hysterectomy, apart from the presence or absence of uterine disease and the patient’s desires. Nevertheless, sparing the uterus is essential to women not only to have normal sexual functioning but to maintain physical and anatomical integrity as well.
Aim. To assess sexual function in a group of patients who underwent CSP or hysterocolposacropexy (HSP).
Materials and Methods. We enrolled 37 patients who underwent surgery for urogenital prolapse (15 HSP, mean age 53 years; 22 CSP, mean age 56 years). Based on a preliminary sexual history and sexual questionnaire, all patients were sexually active before surgery. At a mean follow-up of 39 months, we reassessed the patients using the Female Sexual Function Index (FSFI).
Main Outcome Measure. We considered sexual activity with a score of 30 = good, 23–29 = intermediate, and <23 = poor.
Results. In patients who underwent CSP and HSP, sexual activity was good in 13% and 26%, intermediate in 33% and 21%, and poor in 54% and 53%, respectively; considering also five patients who no longer had sexual activity postoperatively. Nevertheless, the statistical analysis, performed based on the data obtained from the FSFI questionnaire, showed that there were no significant differences between the two groups of points in terms of total score—CSP 21.1 (1.2–33.5) vs. HSP 22.8 (3.6–34.5)—and single domains (desire, arousal, lubrication, orgasm, satisfaction, and pain) (P = not significant).
Conclusions. Our data demonstrated no substantial differences regarding sexual activity in patients in which the uterus has been spared as opposed to those in whom it has been removed. Furthermore, in a small percentage of cases, surgery actually reduced regular sexual activity
Intra-plaque injection of betamethasone and verapamil using a new plunger mechanism syringe with ergonomic leverage handling for the treatment of Peyronie's disease
No full textWe report a review of the literature and our experience in the intra-lesional therapy (medical therapy) for the treatment of Peyronie’s Disease. We use, since 1997, a plunger mechanism syringe with ergonomic leverage handling named Citoject. This syringe develops a high hydraulic pressure, exerting both a pharmacological and a mechanical effect on plaques. The main endpoints of this study is to compare our results with all the data reported in the recent literature about this issue.
From June 2002 to December 2007, we treated 67 men with Peyronie’s disease by administering 10 weekly intra-lesional injections, alternating between betamethasone (4 mg) and verapamil (5 mg). 50 patients (89%) reported plaque-related symptoms during erection. Palpable plaque was present in all
patients. Recurvatum was present in 45 patients (80%).
At a mean follow-up of 30 months, we observed rapid resolution of the symptoms in 48/50 patients (96%). A significant reduction in plaque size was noted in 43% of cases (24/56; p = 0.001). Recurvatum improved only in a small percentage of cases (26.6%), with no progression of recurvatum.
This device represents a good choice for intra-lesional drug administration in Peyronie’s disease. Minimal side effects or adverse reactions were reported by patients, and there was minimal involvement of the normal tissue surrounding
the plaqu
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
