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
Associations among physical activity, perception of stress, and relapse occurrence in multiple sclerosis
No full textBackground: Relapsing-remitting multiple sclerosis (RRMS) is a chronic, immune-mediated disease that is characterized by relapses or periods of worsening symptoms (Lublin & Reingold, 1996). The occurrence of a relapse has been associated with experiencing a stressful event (Mohr, Hart, Julian, Cox, & Pelletier, 2004). Physical activity could potentially influence relapse occurrence directly or indirectly through attenuation of the stress response, but neither of these relationship have been investigated in people with MS. Two theoretical models, the Transactional Model of Stress and Coping and the Cross-Stressor Adaptation Hypothesis, could possibly provide an explanation for how stress is involved in the relationship between physical activity and relapse occurrence.
Objective: The two aims of this retrospective study were to determine: 1) Is physical activity associated with a decreased number of relapses within a year; and 2) Is the relationship between physical activity and relapse occurrence mediated or moderated by stress?
Methods: The sample included 47 females with RRMS who had characteristics for increased risk of relapse occurrence (female, short disease duration, young age of adult onset). Participants completed the Perceived Stress Scale (PSS), Modified Activity Questionnaire (MAQ), and a recall of any relapses during the previous year. Participants further wore a pedometer for 7 days.
Results: Nineteen or 40% of the participants had a relapse during the previous year. There were statistically significant differences between those who did and did not have a relapse in the previous year for pedometer steps (t = 2.13, p < 0.05), PSS (t = 2.05, p < 0.05), and MAQ (t = 1.96, p < 0.05).The occurrence of a relapse was positively associated with PSS (r = .29) and negatively associated with MAQ (r = –.29) and pedometer (r= –.30). The regression analyses for mediation effects showed the relationship between physical activity (i.e. both pedometer and MAQ separately) were slightly attenuated, but non-significant when relapse occurrence was regressed on both physical activity and PSS. For moderation, pedometer steps were significantly correlated with relapse in the low stress group (r = .435) but not in the high stress group (r = .076), and MAQ was significantly correlated with relapse occurrence in the high stress group (r = .345), but not in the low-stress group (r = .207).
Conclusion: Physical activity was moderately, significantly, and inversely related to relapse occurrence in persons in the early stages of RRMS. This means that physical activity behavior could potentially be a determinant of relapse occurrence or that inactivity could be a consequence of having a relapse. There were weak and inconsistent results with perception of stress as a mediator or moderator of the relationship between physical activity and relapse occurrence in MS. These results did not fully support the Transactional Model of Stress and Coping or the Cross-Stressor Adaptation Hypothesis for understanding the decrease in relapses seen with physical activity in persons with MS.Item withdrawn by Mark Zulauf ([email protected]) on 2011-07-20T13:28:51Z

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

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.
