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
Management of mesh complications following surgery for stress urinary incontinence or pelvic organ prolapse: a systematic review.
No full textBACKGROUND:Mesh surgery for stress urinary incontinence or pelvic organ prolapse can result in complications such as mesh exposure, mesh extrusion, voiding dysfunction, dyspareunia, and pain. There is limited knowledge or guidance on the effective management for mesh-related complications. OBJECTIVE:To determine the best management of mesh complications; a systematic review was conducted as part of the national clinical guideline 'Urinary incontinence (update) and pelvic organ prolapse in women: management'. SEARCH STRATEGY:Search strategies were developed for each indication for referral. SELECTION CRITERIA:Relevant interventions included complete or partial mesh removal, mesh division, and non-surgical treatments such as vaginal estrogen. DATA COLLECTION AND ANALYSIS:Characteristics and outcome data were extracted, and as a result of the heterogeneous nature of the data a narrative synthesis was conducted. MAIN RESULTS:Twenty-four studies were included; five provided comparative data and four studies stated the indication for referral. Reported outcomes (including pain, dyspareunia, satisfaction, quality of life, incontinence, mesh exposure, and recurrence) and the reported incidences of these varied widely. CONCLUSIONS:The current evidence base is limited in quantity and quality and does not permit firm recommendations to be made on the most effective management for mesh-related complications. Robust data are needed so that mesh complications can be managed effectively in the future. TWEETABLE ABSTRACT:Systematic review demonstrates that the outcomes following mesh revision surgery are highly variable
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
Conservative management of pelvic organ prolapse
No full textPelvic organ prolapse is a common condition with 1 in 10 women undergoing surgery during their lifetime. In the community 8% of women complain of the symptom of a vaginal bulge which is the symptom that most closely correlates with the finding of a prolapse on examination. Pelvic organ prolapse can impair urinary, bowel and sexual function. The NICE National Guideline Urinary Incontinence and Pelvic Organ prolapse in Women: Management makes recommendations on the assessment and treatment of pelvic organ prolapse. The most important part of prolapse management is obtaining a comprehensive pelvic floor history and understanding the woman's treatment goals and expectations. A standardised examination aids further decision making. Conservative treatment options include observation, lifestyle advice, pelvic floor muscle training and use of a pessary. Treatment choice is guided by patient preference.</p
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
Surgical management of stress urinary incontinence
No full textWomen are seeking treatment for stress urinary incontinence more readily due to increasing awareness of minimally invasive surgical solutions and greater expectations of pelvic floor health with advancing age. Concerns have been raised regarding the safety of tape procedures and clinicians need to be aware of the recent guidance published on this by the MHRA. Surgery for stress urinary incontinence should only be undertaken in women following a comprehensive assessment and when conservative treatments have failed after a multidisciplinary team discussion. The current evidence favours a retro-pubic mid-urethral tape procedure using the bottom-up approach, or colposuspension. Pubo-vaginal slings using autologous rectus sheath fascia have a good success rate, but also have significantly higher incidence of operative morbidity and voiding problems. Urethral bulking agents are a safe alternative, especially in those women where more invasive surgery is not desired. It is important to counsel that they have a lower success rate and repeat injections are often needed
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
