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
DIAGNOSTICS, GENOMICS, AND MANAGEMENT OF DIAPORTHE HUMULICOLA, THE CAUSAL AGENT OF HALO BLIGHT OF HOPS
No full textThesis (Ph.D.)--Michigan State University. Plant Pathology - Doctor of Philosophy, 2025This dissertation explores various aspects of the pathogen D. humulicola. The research tested multiple fungicide products to determine effective management strategies for the disease. Additionally, a qPCR tool was developed for the detection of D. humulicola in different plant materials. Lastly, a genome was produced, and a population genetics study was conducted using D. humulciola isolates from the eastern United States and Canada. The first research objective of this dissertation was to determine if fungicides could be used for the treatment of halo blight. For three years field trials were conducted using 10 fungicides registered for use hop to determine their efficacy against halo blight. To validate field results, the EC50 value was determined for some of the active ingredient including flutriafol, tebuconazole + fluopyram, cyflufenamid, and trifloxystrobin + salicylhydroxamic acid (SHAM). A discriminatory dose was used to test the sensitivity of 206 D. humulicola isolates in a poison agar assay. Results showed that tebuconazole + fluopyram decreased the incidence and severity of halo blight in the field. Also, this product had EC50 values of 2.26 x 10-1 ppm and significantly reduced the growth of most of the isolates tested. Trifloxystrobin + SHAM decreased the presence of halo blight in the field, but some isolates were not inhibited by the discriminatory dose concentration. The second research objective was to develop a diagnostic tool for D. humulicola. A quantitative polymerase chain reaction (qPCR) assay based on the translation elongation factor 1-alpha gene was developed. We assessed this assay for direct detection of D. humulicola in plant tissue and investigated aspects of the disease cycle through three distinct experiments: 1) detection of D. humulicola in hop rhizomes to determine the colonization range of the pathogen, 2) determining how quickly can D. humulicola be detected in hop leaves post inoculation, and 3) monitoring the presence of D. humulicola in cones in a hop yard and comparing isolation methods and the assay. The limit of detection for the assay was 100 fg of DNA. The assay showed no cross-reactivity with other hop pathogens or endophytes, nor with other Diaporthe species tested. Detection of D. humulicola occurred one day after inoculation. The assay detected D. humulicola in both apparently healthy and diseased rhizome tissue. The assay successfully detected the pathogen in individual hop cones and inflorescences throughout the season, surpassing the culture-based method in positive identification rates. The third objective was to produce and annotate a genome for D. humulicola. The draft genome for D. humulicola, was assembled with both long and short read sequencing. The draft genome consists of 49.82 MB assembled into 180 contigs, with a GC content of 51.2%. The genome was annotated, and 11,773 genes were predicted, including 2,752 genes with common names. Finally, the genome was used to conduct a population genetics experiment using 64 different D. humulicola isolates from Michigan, New York, Minnesota, and Canada. Single nucleotide polymorphisms (SNPs) were discovered and filtered using GATK. Population Structure was determined using STRUCTURE v.2.3.4 and using the Evanno method the populations cluster into 4 or 6 different populations. Using Fst Minnesota isolates appear to have high levels of population differentiation when compared to the different populations. Mating types were determined for each isolate where Mat-1-2-1 were the larger part of the population with 59 percent of the isolates having this locus. This dissertation also includes an extension fact sheet for halo blight, and disease notes for different occurrences of halo blight in the United States and Canada.Description based on online resource.

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.
