Injection devices for bulking agents in uro-gynaecology.
No full textStress urinary incontinence (SUI) affects a large proportion of middle-aged and elderly women. When all conservative means are ineffective, a surgical treatment including retropubic suspension, pubovaginal and tension-free slings, is contemplated. Intra-urethral injections with bulking agents have been used as an alternative to the mentioned surgical procedures with alternate results. Many urethral bulking agents are available, such as bovine glutaraldehyde cross linked (GAX) collagen, polytetrafluoroethylene (Teflon), polydimethyl-sillxane elastomer (silicone), carbon coated zirconium beads, hyaluronic acid/dextranomer, and autologous tissues such as fat and cartilage. These substances may be injected in a retrograde or antegrade fashion in the periurethral tissue and whether one route of injection is better than another is not well documented in the literature. We briefly describe the main injection techniques and devices of the most common bulking agents used in the treatment of female SUI
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

A unique case of late complication of rectum mesh erosion after laparoscopic sacrocolpopexy
No full textSacrocolpopexy, a surgical technique with a low morbidity rate, is a valid procedure for repairing vaginal vault prolapse. To our knowledge, only 1 case of rectum erosion after open sacrocolpopexy has been reported in the literature, and there is no record of any such incident after laparoscopic sacrocolpopexy. We report the first case of mesh erosion involving the rectum instead of the vagina assessed 8 years after laparoscopic sacrocolpopexy
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
