Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
Investigating the molecular epidemiology of Norwegian blood culture isolates of Klebsiella pneumoniae using whole genome sequencing
Full text linkAbstract
Antimicrobial resistance (AMR) is a rapidly increasing threat to public health, and was in 2019 listed as one of top ten global health threats by the World Health Organization (WHO). The gram-negative Enterobacteriaceae Klebsiella pneumoniae (K. pneumoniae) has as a ranking of “Priority 1: Critical” on WHOs list of pathogens, due to its development of multi-drug resistance (MDR) towards last-line antibiotics.
The development of new effective antibiotics, as well as research on this bacteria is much needed to limit and ultimately reduce the spread and evolvement of resistant and highly pathogenic strains. Strengthened prevention and infection control and increased surveillance as well as utilization of the “One Health” approach are all actions to regard for an effective strategy against AMR.
Whole genome sequencing (WGS) can aid in characterization, detection, tracking and surveillance of the evolution and emergence of AMR related strains. WGS enables accurate characterization of transmission and outbreaks by allowing comparison of clinical isolates with an accuracy of a single nucleotide difference. WGS also provides knowledge of the presence resistance- and virulence genes, and the number of SNPs in the whole genome, as well as information on conserved and variable genes in various lineages. Phylogenetic analysis, such as core genome MLST, can uncover specific sequence types (STs) associated with resistance- or virulence genes, and genetic relations between clinical isolates.
PFGE was and still is considered the “gold standard” for bacterial strain typing in many laboratories. This method was therefore compared to a WGS based strain typing method to see if there is correlation or large differences between effectiveness, reliability and resolution in the two methods.
In this thesis, a collection of 722 K. pneumoniae strains provided by the NORKAB study was whole genome sequenced and analyzed to describe the genetic epidemiology between the isolates. Investigations were carried out with the phylogenetic analysis methods; core genome analysis and single nucleotide polymorphism (SNP) analysis. The phylogenetic analysis of the WGS data was compared with phylogenetic analysis of pulse field gel electrophoresis (PFGE) data.
In the investigated K. pneumoniae population, multilocus sequence typing (MLST) analysis revealed a diverse distribution, with a total of 378 different STs, with seven prevalent variants, ST107 (n=67), ST20 (n=23), ST37 (n=20), ST45 (n=18) and ST307, ST25 and ST26 (n=12). Locus variants (LV) we detected in 178 isolates, distributed among 147 different LVs. In addition, three new STs were assigned to three of the isolates from the population.
No significant geographical differences were found in the distribution of STs, except for a few local build-ups of ST10 (8/8) and ST107 (49/67) in both the West and the South regions, and ST220 (5/6) and ST29 (5/8) in the East region, but the Middle region was under-represented with only one participation hospital.
The most prevalent ST, ST107, was investigated through PFGE and core genome SNP analysis. PFGE analysis indicated clonality in 33/37 isolates, based on a one band difference in the DNA fingerprints, and no positional differences. Core genome SNP analysis of the same isolates suggested close relations, based on an average SNP difference of ~15±6. The suggested SNP difference for indication of clonal isolates is ≤10. This showed that core genome SNP analysis has a stronger discriminative power and a higher resolution to differentiate isolates than that of PFGE. The core genome SNP analysis did not suggest clonality in the same number of isolates as the DNA fingerprint analysis did.
A large diversity of sequence types was identified among clinical isolates of K. pneumoniae from five geographical regions of Norway. The most prevalent, ST107, was found in all regions, with higher incidence in the South- and West regions. The majority of isolates were characterized as closely related, and some were characterized as clonal. Comparison of PFGE and core genome SNP analysis of the isolates suggested a higher discriminative power in the latter method

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.
