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
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.

Valutazione della sensibilita all?itraconazolo di isolati ambientali e clinici di miceti del genere Aspergillus
No full textGli Aspergilli sono funghi ambientali che frequentemente provocano gravi infezioni in pazienti neutropenici. Recentemente nel nord Europa sono state segnalate numerose resistenze agli azoli, farmaci di prima scelta nel trattamento di tali infezioni. Scopo della presente tesi sperimentale è stato valutare la sensibilità all'itraconazolo, con il metodo della microdiluizione EUCAST E. DEF 9.1, di 107 isolati identificati a partire da substrati provenienti da 96 campionamenti effettuati dal 2011. Sono stati esaminati N. 72 campioni ambientali e N. 24 prelevati da casi clinici di volatili.
Gli isolati micotici provenienti dai campioni ambientali ammontano a N. 94 di cui N. 7 A. fumigatus, N. 45 A. niger, N. 27 A. flavus, N. 10 A. terreus, N. 3 A. ustus, e N. 2 A. candidus.
Gli isolati clinici erano rappresentati da N. 13 A. fumigatus risultati sempre sensibili all'itraconazolo alle prove di microdiluizione.
Tra i campioni ambientali, N. 14 isolati di A. niger su 45, N. 2/27 di A. flavus e N. 1/10 di A. terreus hanno mostrato capacità di crescita su RPMI 1640 fino a concentrazione di itraconazolo ≥ 8mg/L. Nessuno tra i nostri isolati delle specie di A. candidus, A. ustus e A. fumigatus ha mostrato invece resistenza alle medesime prove di sensibilità.
The genus Aspergillus are environmental moulds that frequently cause severe infections in neutropenic patients. Recently in northern Europe various resistances to azoles have been reported, drugs of first line in the treatment of such infections. The purpose of this experimental thesis was to evaluate the susceptibility in vitro to itraconazole, with the method of EUCAST E. DEF 9.1 microdilution method of 107 isolates identified starting from 96 substrates samples taken from 2011. No. 72 environmental samples and No. 24 taken from clinical cases of birds were examined.
Fungal isolates from environmental samples amounted to No. 94: No. 7 A. fumigatus, No. 45 A. niger, No. 27 A. flavus, No. 10 A. terreus, No. 3 A. ustus, and No. 2 A. candidus.
The clinician isolates were represented by No. 13 A. fumigatus always resulted susceptible to itraconazole in microdilution tests.
Among environmental samples, No. 14/45 isolates of A. niger, No. 2/27 of A. flavus and No. 1/10 of A. terreus showed growth capacity on RPMI 1640 broth up to ≥ 8mg / L of final itraconazole concentration.
Instead, none of our isolates of the species of A. candidus, A. fumigatus and A. ustus were able to grow with 8 mg/L of itraconazole
