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

ROSACEA: FACTORS AFFECTING THE COURSE AND OCULAR INVOLVEMENT Rosacea is a dermatose occuring in the central region of the face characterized by episodic flushing, erythema, telengiectasia, papules and papulopustules. The incidence of ocular signs and symptoms in rosacea were detected to be variable in different series. In this study demographic, clinical features and provoking factors in 50 patients with rosacea were investigated. In addition the ocular signs and symptoms were evaluated in 32 of them. The rosacea patients underwent testing of tear break-up time, Schirmer testing and rose Bengal staining and the results were compared with that of 15 controls. Rosacea was detected to be more common in women, and the severity of the disease were not significantly different regarding gender. The lesions were found to be symmetrically distrubuted, the cheek being the most affected region. More than 50% of the patients reported an increase in symptoms with sun exposure, stress and soaps. All patients showed signs and symptoms of ocular disease. The most frequent ocular symptoms were itching, burning and photosensitivity, and the most frequent ocular signs were blepharitis, meibomitis, and telengiectasia. The stage of cutaneous rosacea showed a positive correlation with the number of ocular signs. The difference between flushing and the number of ocular signs and symptoms were not statistically significant. The mean tear break-up time of the patients and the controls were 10,00 and 13,27 seconds respectively. This difference was found to be statistically significant The Schirmer test showed an average of 11,56mm of wetting with rosacea, while the controls had an average of 14,27mm of wetting and the difference was statistically significant Rose Bengal staining scores were higher in rosacea patients than controls. In conclusion, all sources of local irritation such as sun exposure, stress and soaps should be avoided in rosacea. Thus, protection against sunlight and avoidance of stress requires special emphasis. The ocular involvement should be always kept in mind for early diagnosis with basic tests and appropriate treatment will prevent the development of severe ocular complications. 577. Rozase sıklikla yüze yerleşen, flushing atakları, eritemli zeminde telenjiektaziler, papüller ve papülopüstüllerle karakterize bir deri hastalığıdır. Hastalığa oküler yakınma ve bulgular da eşlik edebilmektedir. Bu çalışmada 50 rozaseli hastada demografik ve klinik özellikler ve hastalığın şiddetini etkileyen faktörler araştırıldı. Ek olarak bu hastaların 32'sinde oküler yakınma ve bulgular değerlendirildi, gözyaşı kırılma zamanı ölçüldü, Schirmer testi uygulandı ve rose bengal boyaması yapıldı. Sonuçlar 15 kontrol olgusuyla karşılaştınldj. Rozasenin kadınlarda daha sık görülen ve her iki cinste de benzer şiddette seyreden bir dermatoz olduğu gözlendi. Hastalığın genellikle simetrik yerleştiği ve en sık tutulum yerinin yanaklar olduğu saptandı. Hastaların %50'den fazlası güneş, stres ve yüze sabun kullanımıyla yakınmalarında artma tanımladılar. Hastaların tümünde rozase ile ilgili olabilecek en az bir oküler yakınma veya bulgu olduğu gözlendi. En sık. görülen oküler yakınmalar kaşıntı, yanma, fatofobi, en sık oküler bulgular ise blefarit, meibomit ve telenjiektazi olarak saptandı. Hastalığın evresiyle oküler bulgu sayıları arasında pozitif korelasyon olduğu gözlendi. Ancak hastalığın evresi, papül ve püstül sayıları ile gözyaşı fonksiyon testleri arasında korelasyon saptanmadı. Flushing olup olmamasıyla oküler yakınma ve bulgu sayılan ve göz yaşı fonksiyon testleri arasında da ilişki saptanmadı. Ortalama gözyaşı kırılma zamanı hastalarda 10,00 saniye, kontrollerde ise 13,27 saniye olarak saptandı. Fark istatistiksel olarak anlamlı bulundu. Hastalarda ortalama 11,56 mm, kontrollerde ise 14,27 mm olarak saptanan Schirmer testi sonuçları hasta grubunda kontrol grubundan anlamlı derecede daha düşük bulundu. Rose bengal boyanma skorları hasta grubunda kontrollerden anlamlı derecede daha yüksekti. Sonuç olarak, güneş, stres, sabun kullanımı gibi hastalar tarafından hastalık şiddetini arttırdıkları bildirilen unsurların olabildiğince ortadan kaldırılması, hastalığın kontrol altına alınması için gerekli önlemlerden biri olmalıdır. Rozasede tüm hastalarda değişen şiddetlerde olmakla birlikte oküler tutulumunun hastalığa eşlik etmesi nedeniyle, ciddi oküler komplikasyonların önlenmesi için hastaların oftalmolojik açıdan da izlemi önemlidir. 5
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.
