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
Comparison of patient-reported breast, arm, and shoulder symptoms and body image after radiotherapy for early breast cancer: 5-year follow-up in the randomised Standardisation of Breast Radiotherapy (START) trials
No full textAbstract: Background Few trials of adjuvant breast radiotherapy have incorporated patient-reported breast symptoms and related areas of quality of life. We assessed these measures in a quality-of-life study that was part of the randomised START (Standardisation of Breast Radiotherapy) trials. Methods In START trial A, 2236 patients were randomly assigned to receive either 39 Gy or 41.6 Gy delivered in 13 fractions over 5 weeks or a global standard of 50 Gy in 25 fractions. In START trial B, 2215 women were randomly assigned to receive either 40 Gy in 15 fractions over 3 weeks or the same control regimen (50 Gy in 25 fractions) as in trial A. 2739 patients were eligible for the quality-of-life study of whom 2208 (81%) were accrued (1129 patients from trial A and 1079 from trial B). Participants completed the EORTC QLQ-C30 and BR23 questionnaires and protocol-specific radiotherapy items up to 5 years after radiotherapy. We compared results across regimens with generalised. estimating equations and survival analyses. The START trials are registered, ISRCTN59368779. Findings At 5 years, up to 40% women reported moderate or marked changes to the breast after radiotherapy, and arm and shoulder pain affected up to a third of patients. Breast symptoms and body image concerns reduced over time. Rates of radiotherapy adverse effects were lower for the 39 Gy regimen in trial A and the 40 Gy regimen in trial B, compared with the 50 Gy control regimen; rates of radiotherapy adverse effects were similar between the 41.6 Gy and 50 Gy regimens in trial A. Adverse change in skin appearance was significantly lower for patients who received 39 Gy compared with those who received 50 Gy (HR 0.63, 95% CO 0.47-0.84) and for those who received 40 Gy compared with those who received 50 Gy (0.76, 0.60-0.97); no significant difference was observed between patients who received 41.6 Gy and those who received 50 Gy in trial A (0.83, 0.63-1.08). Patient self-ratings of breast symptoms discriminated a 10% difference in randomised dose intensity. Up to a third of women reported moderate or marked pain in the arm and shoulder over 5 years whilst more than 10% experienced moderate or marked arm and hand swelling, with no significant difference in arm/shoulder subscale scores between the regimens in trial A or trial B; many baseline arm and shoulder symptoms were associated with prior surgery. Interpretation A substantial proportion of women report moderate or marked breast, arm, and shoulder symptoms over 5 years of follow-up after radiotherapy, but with no detriment to body image. Nonetheless, most patients stand to gain from hypofiractionated radiotherapy regimens with a potential for fewer adverse effects; this strengthens the evidence from the START trials for hypofiractionated regimens for women requiring radiotherapy for early breast cancer
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
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.
