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
Functional Characterisation Of Novel Plasmodium falciparum Proteins And Their Role In Erythrocyte Invasion
Get PDFMalaria caused by Plasmodium falciparum is responsible for the deaths of hundreds of thousands of children every year, and imparts an overwhelming economic burden on the world’s poorest countries. All symptoms of malaria are caused during the asexual blood-stage of the P. falciparum lifecycle, which is reliant on merozoite invasion of host red blood cells (RBCs). Due to its essentiality for parasite survival, and its exposure to the host immune system, merozoite invasion is an attractive target for the development of antimalarial therapeutics. Merozoite invasion is coordinated by a series of secretory organelles, of which the largest and most well characterised are the rhoptries. Previous studies into rhoptry proteins have been strongly foccused on antigens that are secreted from the rhoptries during invasion; primarily due to their promise as vaccine candidates. As such, very little is known about proteins that coordinate rhoptry biogenesis, structure, or function. Prior to this study the P. falciparum proteins Pf3D7_0210600 and Pf3D7_0405200, hereafter referred to as P. falciparum Cytosolically Exposed Rhoptry Leaflet Interacting proteins (PfCERLI) 1 and 2, were largely uncharacterised proteins that previous studies had suggested may play a role in merozoite invasion. We hypothesised that PfCERLI1 and PfCERLI2 were rhoptry proteins that shared an evolutionary relationship and were both essential for merozoite invasion. We aimed to test these hypotheses through bioinformatic analyses, immunofluorescence microscopy, and gene disruption or inducible knockdown. Bioinformatic and phylogenetic analyses showed that cerli1 and cerli2 arose through an ancestral gene duplication of cerli1 that was present in the most recent common ancestor of haematozoa and coccidia. Analysis of the structure of CERLI proteins revealed they possess a conserved motif with the consensus sequence PHISE/DxxP that we have termed PHIS, along with conserved C2 and Pleckstrin homology (PH) domains that are likely ito have a role in membrane association. Using selection linked integration targeted gene disruption (SLI-TGD) we determined that both Pfcerli1 and Pfcerli2 were refractory to gene deletion and likely important for blood-stage growth. To assess their functions, we used an inducible protein knockdown system whereby the addition of glucosamine (GLCN) results in specific mRNA degradation prior to translation. Knockdown of either CERLI1 or CERLI2 resulted in growth inhibition caused by an inability of merozoites to invade RBCs. Immunofluorescnce microscopy and biochemical techniques revealed that both proteins are peripheral membrane proteins that localise to the cytosolic face of the rhoptry bulb. Rhoptry secretion assays showed that knockdown of PfCERLI1, but not PfCERLI2, leads to a defect in the secretion of key rhoptry antigens. By contrast, electron microscopy analysis of rhoptry size indicated a significant increase in rhoptry length following PfCERLI2 knockdown, but no change with PfCERLI1 knockdown. Semi-quantiative super-resolution microscopy analysis determined that knockdown of PfCERLI1 alters rhoptry antigen distribution, and it was shown that both PfCERLI1 and PfCERLI2 knockdown inhibit processing of key rhoptry antigens. The findings of these studies show that the previously uncharacterised proteins, PfCERLI1 and PfCERLI2, are related rhoptry proteins whose functions are essential for maintaining rhoptry morphology, rhoptry secretion, and rhoptry antigen processing.Thesis (Ph.D.) -- University of Adelaide, School of Biological Sciences, 202
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.
