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
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
Klauenrehe als Folge von Mastitiden durch Escherichia (E.) coli – retrospektive Studie zur Prävalenz und zum Langzeit-Outcome von Patienten der Klinik für Wiederkäuer 2012-2023 mit diesem Krankheitskomplex
No full textDiploma thesis - University of Veterinary Medicine Vienna - 2025The aim of this retrospective case-control study was to investigate the relationship between the occurrence of mastitis caused by E. coli and acute laminitis. For this purpose, the medical records of 93 cows with E. coli mastitis were evaluated. The cows were divided into three groups: 1) cows with mastitisscore 1 or 2 without symptoms of acute laminitis; 2) cows with mastitis score 3 without symptoms of acute laminitis; 3) cows with mastitis score 3 and symptoms of acute laminitis. Out of the 93 cows with E. coli mastitis, 19 were assigned to group 1 (20.4 %), 46 to group 2 (49.5 %), and 28 to group 3 (30.1 %). A total of 74 cows (79.6 %) had score 3 mastitis, but only in 28 cows (37.8 %) was also diagnosed an acute laminitis. A higher mastitis score was significantly associated with a higher incidence of acute laminitis (P=0.0004). E. coli mastitis occurred in cows of all three groups mainly in the first third of lactation (53.6 % to 75.6 %) and increased in the third and later lactations (73.3 % to 78.6 %). In cows in groups 2 and 3, examination of the conjunctivae and skin elasticity frequently showed pathological findings in 51.7 % to 78.6 % of the animals. Additionally, the appetite and rumen activity of cows in all three groups were significantly impaired (84.2 % to 89.5 %). In all cows with acute laminitis, a palpable depression around the coronary band on two or more claws was detected by finger palpation. Positive pain palpation of the claws using a hoof tester was detectable in only 63.3 % of the cows, and an increased temperature of the claws was detectable in only 60.7 % of the cows with acute laminitis. All 28 cows showed a stiff gait and lameness. Regarding the survival time of the cows in the three groups, only a trend but no statistically significant differences were assessed. The cows in group 1 had a median survival time of 512 days, while for the cows in group 2 this value was 93 days, and for the cows in group 3 this value was 178 days. From the results of this study, it can be concluded that when a cow is diagnosed with E. coli mastitis with a score of 3, a careful examination of the claws should always be carried out in order not to overlook the acute laminitis that accompanied the E. coli mastitis in around 38 % of cases.Diplomarbeit - Veterinärmedizinische Universität Wien - 2025Ziel dieser retrospektiven Fall-Kontroll-Studie war es Zusammenhänge zwischen dem Auftreten von Mastitiden durch E. coli und akuter Klauenrehe zu untersuchen. Dazu wurden die Krankenakten von 93 Kühen mit E. coli-Mastitiden ausgewertet. Die Kühe wurden in drei Gruppen unterteilt: 1) Kühe mit Mastitis-Score 1 oder 2 ohne Symptome einer akuten Klauenrehe; 2) Kühe mit Mastitis-Score 3 ohne Symptome einer akuten Klauenrehe; 3) Kühe mit Mastitis-Score 3 und Symptomen einer akuten Klauenrehe. Von den 93 Kühen mit einer E. coli-Mastitis wurden 19 der Gruppe 1 (20,4 %), 46 der Gruppe 2 (49,5 %) und 28 Kühe der Gruppe 3 (30,1 %) zugeordnet. Insgesamt zeigten 74 Kühe (79,6 %) eine Score 3-Mastitis, jedoch nur bei 28 Kühen (37,8 %) wurde auch eine akute Klauenrehe diagnostiziert. Ein höherer Mastitis-Score ging signifikant mit einem häufigeren Auftreten von akuter Klauenrehe einher (P=0,0004). E. coli-Mastitiden traten bei Kühen aller drei Gruppen zu 53,6 % bis 75,6 % im ersten Laktationsdrittel und vermehrt in der dritten und in höheren Laktationen auf mit 73,3 % bis 78,6 %. Bei den Kühen der Gruppen 2 und 3 zeigte die Untersuchung der Lidbindehäute und der Hautelastizität pathologische Befunde bei 51,7 % bis zu 78,6 % der Tiere. Zudem waren die Fresslust und Pansentätigkeit bei Kühen in allen drei Gruppen signifikant beeinträchtigt (84,2 % bis 89,5 %). Bei allen Kühen mit akuter Klauenrehe war das Einsinken des Saumbandes an zwei oder mehreren Klauen mittels Fingerpalpation nachweisbar, wohingegen eine positive Schmerzpalpation an den Klauen nur bei 63,3 % der Kühe, und eine erhöhte Temperatur der Klauen nur bei 60,7 % der Kühe mit akuter Klauenrehe feststellbar war. Alle 28 Kühe zeigten ein spießiges Gangbild und Lahmheit. Hinsichtlich der Überlebenszeit der Kühe in den drei Gruppen konnte nur ein tendenzieller aber kein statistisch signifikanter Unterschied festgestellt werden. Die Kühe der Gruppe 1 wiesen eine Überlebenszeit von 512 Tagen (Median) auf, wohingegen dieser Wert bei den Kühen der Gruppe 2 93 Tage, und bei den Kühen der Gruppe 3 178 Tage betrug. Aus den Resultaten dieser Studie lässt sich schlussfolgern, dass bei Diagnosestellung einer E. coli-Mastitis mit Score 3 bei einer Kuh immer auch eine sorgfältige Untersuchung der Klauen vorgenommen werden sollte, um eine in ca. 38 % der Fälle damit einhergehende akute Klauenrehe nicht zu übersehen
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.
