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
Potential of domestic and wild cats as reservoirs of Leptospira spp.
No full textLeptospiroza je najraširenija zoonoza u svijetu i bolest prirodnih žarišta, čiji su do sad
jedini utvrđeni rezervoari glodavci. Leptospiroza je u pravilu akutna septikemijska bolest
domaćih i divljih životinja ali i ljudi uzrokovana patogenim bakterijama Leptospira spp. Zbog
svoje kompleksne epizootiologije i nedovoljno zabilježenih podataka o domaćim i divljim
mačkama kao potencijalnim rezervoarima leptospiroze, provedeno je istraživanje u koje je
uključeno ukupno četrdeset uzoraka bubrega, od toga osamnaest uzoraka bubrega divljih
mačaka i dvadeset i dva uzorka bubrega domaćih mačaka. Uz neotkriveno pitanje konačnog
broja vrsta životinja kao rezervoara leptospiroze, ovu bolest odlikuje rekonvalescentno
kliconoštvo, velike divergencije kliničke slike i dugotrajno održavanje bakterija u tlu,
vegetaciji i vodi, što predstavlja dodatan problem u dijagnosticiranju bolesti i prikupljanju svih
potrebnih podataka o rezervoarima. Prikupljeni uzorci bubrega su u istraživačkom radu u
sedmomjesečnom periodu homogenizirani, iz njih je izolirana DNA NucleoSpin® Tissue
metodom te je nakon izrade glavne smjese potrebne za provođenje lančane reakcije
polimerazom u stvarnom vremenu (RealTime PCR), pojedini uzorak izolirane DNA bio
pomiješan s pripravljenom smjesom i kao takav bio spreman za analizu u Rotor-Gene Q PCR
uređaju. Nakon provedene izolacije DNA i obrade uzoraka molekularnom metodom RealTime
PCR, utvrđeno je kako niti jedan uzorak bubrega divljih mačaka nije bio pozitivan na infekciju
Leptospirom spp., dok je u domaćih mačaka dokazan jedan pozitivan uzorak na infekciju
Leptospirom spp. Iako dobiveni negativni rezultati opovrgavaju činjenicu da bi divlje mačke
potencijalno uz glodavce, zbog svojih životnih i predatorskih tendencija, mogle biti rezervoari
bakterije Leptospira spp., ovu hipotezu potrebno je dodatno istražiti, uzimajući u obzir veće
uzorke populacije i širu geografsku rasprostranjenost potencijalnih rezervoara. Dokaz
Leptospire spp. u uzorku bubrega domaće mačke implicira na njihov potencijal rezervoara ove
bolesti, iako to ovim istraživanjem nije potvrđeno na temelju samo jednog pozitivnog uzorka.Leptospirosis is a zoonosis occurring worldwide, caused by pathogenic spirochaetes
Leptospira spp. The only known reservoirs for this disease so far are rodents. In most
recorded cases, leptospirosis is an acute septicemic disease of domestic and wild animals, as
well as humans. Due to its complex epizootiology and insufficient recorded data on domestic
and wild cats as potential reservoirs of leptospirosis, a study was conducted that included a
total of forty kidney samples, of which eighteen kidney samples were of wild cats and
twenty-two kidney samples were of domestic cats. In addition to the undiscovered finite
number of animal species as reservoirs of leptospirosis, this disease is characterized by
convalescent carrier-state, large divergences of the clinical symptoms and long-term
maintenance of bacteria in the soil, vegetation and water, which represents an additional
problem in the diagnosis of the disease and the collection of all necessary data on the
reservoirs. The collected kidney samples were homogenized during the seven-month research
period, their DNA was isolated using the NucleoSpin® Tissue method, and after the
preparation of the main mixture required for conducting real-time polymerase chain reaction
(RealTime PCR), every single sample of the isolated DNA was mixed with the prepared
mixture, and as such was ready for analysis in the Rotor-Gene Q PCR machine. After DNA
isolation and sample processing using the RealTime PCR molecular method, it was
determined that not a single sample of the wild cat kidney was positive, meaning no
Leptospira spp. was discovered in samples. Only one domestic cat kidney sample was tested
positive. Although the obtained negative results refute the fact that wild cats could
potentially, in addition to rodents, due to their lifestyle and predatory tendencies, to be
reservoirs of Leptospira spp., this hypothesis needs to be further investigated, taking into
account larger population samples and a wider geographical distribution of potential
reservoirs. The evidence of Leptospire spp. in a kidney sample of a domestic cat implies that
they could be the potential reservoir of this disease, although it was not confirmed by this
research based on only one positive sample
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.
