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
Rhizoctonia in Idaho Wheat, Barley and Common Bean Crops: Isolate Characterization and Potential Chemical Control
No full textRhizoctonia and associated fungi are an important group of soil-borne pathogens. Three groups of Rhizoctonia fungi are important for plant diseases, these are the multinucleate Rhizoctonia solani and Waitea circinata, as well as binucleate Rhizoctonia species (BNR). The Rhizoctonia species complex is characterized through the affinity for hyphal fusion and isolates can be assigned to anastomosis groups (AGs) based on the specific hyphal fusion affinity. The Rhizoctonia solani complex is comprised currently of thirteen known AGs, with twenty-nine subgroups. The BNR complex consist of twenty AGs with eight subgroups, including the most recently found AG W, found in China on potatoes (Solanum tuberosum) in 2015. There are five varieties that are known within Waitea circinata in the newly placed Corticacaeae family. AGs can differ in, means of dispersal, host range, fungicide sensitivity (Kataria and Gisi 1999) and aggressiveness, even to certain plant parts, such as R. solani AG 8 almost exclusively infecting the roots of potatoes (Woodhall et al. 2008). Multiple AGs have been implicated causing disease in wheat, barley and common beans. Optimum disease management based on the knowledge of the AG, or even AG subgroup present, is essential for correct diagnosis. Presently there is limited knowledge of the AGs present on wheat, barley and common bean crops in Idaho. Furthermore, there is very limited knowledge of the AGs present in Idaho and the specific diseases they cause, particularly for Southern Idaho where there is a diverse range of crops grown. Therefore, this study aimed to determine which species, AGs or subgroups are associated with Rhizoctonia diseases were present in wheat, barley and common bean crops in Idaho. 118 commercial wheat and barley fields and 102 commercial common bean fields were sampled in 2018, 2019 and 2020 resulting in 238 wheat and barley isolates and 188 common bean isolates of Rhizoctonia and related groups. Isolate identity was determined using rDNA ITS sequencing and phylogenetic analysis with known reference strains. Of the isolates collected, Waitea circinata varieties were most prevalent in wheat and barley, while AG 4 HG-II was the most prevalent in common beans. Phylogenetic placement showed three unidentified BNR isolates and five unidentified Waitea circinata varieties for wheat and barley. Phylogenetic placement for beans showed two unidentified AG 11 clades. For cereal fields, the relative incidence of Rhizoctonia solani AGs 2-1, 4 HG-II, 5, 8 and BNR AG D (I) was also determined using real-time PCR on directly extracted soil DNA samples. This determined that AG2-1 was widely present in cereal fields prior to planting. With 62 wheat and barley isolates and 61 common bean isolates, replicated glasshouse experiments were undertaken to determine their relative aggressiveness to each host. For cereals BNR AG D was the most aggressive, whilst AG 4 HG-I was most aggressive for beans. Finally, the effectiveness of various fungicides to control Rhizoctonia was evaluated in a laboratory based EC50 assay to 23 isolates, whilst for AG 11, which was determined to significantly reduce bean yields in preliminary experiments, a field and glasshouse experiment was undertaken to determine the effectiveness of serval fungicides to control the pathogen in pinto beans. These experiments indicate that inpyrfluxam and prothioconazole showed most potential to manage the pathogen.masters, M.S., Plant, Soil and Entomological Sciences -- University of Idaho - College of Graduate Studies, 2021-0
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.
