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
Surgical interventions for the management of chronic pelvic pain in women
No full textBackground: chronic pelvic pain (CPP) is a common gynaecological condition accounting for 20% of all gynaecological referrals. There are wide ranges of causes with overlapping symptomatology, therefore the management of the condition is a formidable challenge for clinicians. The aetiology of CPP is heterogeneous and in many cases, no clear diagnosis can be reached. It is in this scenario that the label of chronic pelvic pain syndrome (CPPS) can be applied. We defined women with CPPS as having a minimum duration of pain of at least 6 months, including with a diagnosis of pelvic congestion syndrome, but excluding pain caused by a condition such as endometriosis. Many surgical interventions have been tried in isolation or in conjunction with non-surgical interventions in the management with variable results. Surgical interventions are invasive and carry operative risks. Surgical interventions must be evaluated for their effectiveness prior to their prevalent use in the management of women with CPPS.Objectives: to review the effectiveness and safety of surgical interventions in the management of women with CPPS.Search methods: we searched the Cochrane Gynaecology and Fertility Group (CGF) Specialised Register of Controlled Trials, CENTRAL, MEDLINE, Embase and PsycINFO, on 23 April 2021 for any randomised controlled trials (RCT) for surgical interventions in women with CPPS. We also searched the citation lists of relevant publications, two trial registries, relevant journals, abstracts, conference proceedings and several key grey literature sources.Selection criteria: RCTs with women who had CPPS. The review authors were prepared to consider studies of any surgical intervention used for the management of CPPS. Outcome measures were pain rating scales, adverse events, psychological outcomes, quality of life (QoL) measures and requirement for analgesia.Data collection and analysis: Two review authors independently evaluated studies for inclusion and extracted data using the forms designed according to Cochrane guidelines. For each included trial, we collected information regarding the method of randomisation, allocation concealment, blinding, data reporting and analyses. We reported pooled results as mean difference (MDs) or odds ratios (OR) and 95% confidence interval (CI) by the Mantel-Haenszel method. If similar outcomes were reported on different scales, we calculated the standardised mean difference (SMD). We applied GRADE criteria to judge the overall certainty of the evidence.Main results: our studies met our inclusion criteria involving 216 women with CPP and no identifiable cause. Adhesiolysis compared to no surgery or diagnostic laparoscopy We are uncertain of the effect of adhesiolysis on pelvic pain scores postoperatively at three months (MD -7.3, 95% CI -29.9 to 15.3; 1 study, 43 participants; low-certainty evidence), six months (MD -14.3, 95% CI -35.9 to 7.3; 1 study, 43 participants; low-certainty evidence) and 12 months postsurgery (MD 0.00, 95% CI -4.60; 1 study, 43 participants; very low-certainty evidence). Adhesiolysis may improve both the emotional wellbeing (MD 24.90, 95% CI 7.92 to 41.88; 1 study, 43 participants; low-certainty evidence) and social support (MD 23.90, 95% CI -1.77 to 49.57; 1 study, 43 participants; low-certainty evidence) components of the Endometriosis Health Profile-30, and both the emotional component (MD 32.30, 95% CI 13.16 to 51.44; 1 study, 43 participants; low-certainty evidence) and the physical component of the 12-item Short Form (MD 22.90, 95% CI 10.97 to 34.83; 1 study, 43 participants; low-certainty evidence) when compared to diagnostic laparoscopy. We are uncertain of the safety of adhesiolysis compared to comparator groups due to low-certainty evidence and lack of structured adverse event reporting. No studies reported on psychological outcomes or requirements for analgesia. Laparoscopic uterosacral ligament ablation or resection compared to diagnostic laparoscopy/other treatment We are uncertain of the effect of laparoscopic uterosacral ligament/nerve ablation (LUNA) or resection compared to other treatments postoperatively at three months (OR 1.26, 95% CI 0.40 to 3.93; 1 study, 51 participants; low-certainty evidence) and six months (MD -2.10, 95% CI -4.38 to 0.18; 1 study, 74 participants; very low-certainty evidence). At 12 months post-surgery, we are uncertain of the effect of LUNA on the rate of successful treatment compared to diagnostic laparoscopy. One study of 56 participants found no difference in the effect of LUNA on non-cyclical pain (P = 0.854) or dyspareunia (P = 0.41); however, there was a difference favouring LUNA on dysmenorrhea (P = 0.045) and dyschezia (P = 0.05). We are also uncertain of the effect of LUNA compared to vaginal uterosacral ligament resection on pelvic pain at 12 months (MD 2.00, 95% CI 0.47 to 3.53; 1 study, 74 participants; very low-certainty evidence). We are uncertain of the safety of LUNA or resection compared to comparator groups due to the lack of structured adverse event reporting. Women undergoing LUNA may require more analgesia postoperatively than those undergoing other treatments (P < 0.001; 1 study, 74 participants). No studies reported psychological outcomes or QoL.Authors' conclusions: we are uncertain about the benefit of adhesiolysis or LUNA in management of pain in women with CPPS based on the current literature. There may be a QoL benefit to adhesiolysis in improving both emotional wellbeing and social support, as measured by the validated QoL tools. It was not possible to synthesis evidence on adverse events as these were only reported narratively in some studies, in which none were observed. With the inadequate objective assessment of adverse events, especially long-term adverse events, associated with adhesiolysis or LUNA for CPPS, there is currently little to support these interventions for CPPS.</p
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

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.
