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
Relationship of Gout and Dyslipidemia
No full textGout is an inflammatory response to monosodium urate (MSU) crystals that may exist asymptomatically for months or years, until the first gout attack occurs. The genetic or biochemical factor/s predisposing certain people with urate crystals, but not all, to initiate a gout attack, are poorly understood. Co-existence of gout with dyslipidemia is very common therefore this study was designed to investigate the lipid-related pheno- and genotypes as additional risk factor/s for gout/serum urate along with testing of possible gene-environment interactions to influence the gout risk.
New Zealand (NZ) participants gout cases (n=1198), defined by the American Rheumatology Association preliminary classification criteria, and self-reported controls (n=1084), were the basis for this study. For very low-density lipoprotein (VLDL) analysis, serum samples of 180 male gout cases and healthy controls were fractionated using size exclusion chromatography. Triglyceride (TG), cholesterol and apolipoprotein B (apo B) levels were measured using colorimetric assays and enzyme-linked immunosorbent assay (ELISA), respectively. The Mendelian Randomization approach investigated the causal associations of TG and serum urate in Atherosclerosis Risk in Communities (ARIC) and Framingham Heart Study (FHS) European cohorts where genetic data was either genotyped or imputed. Selected TG and apo B related SNPs were genotyped in NZ sample sets using Taqman genotyping. For gene-environment interaction analysis, alcohol consumption data were obtained by consumption frequency questions in all study cohorts. All analyses were performed using STATA.
Results showed that VLDL TG levels were significantly higher in NZ European and Polynesian gout cases compared to non-gout controls. This increase was driven by the overproduction of VLDL particles in the European participants and by the TG-enrichment of existing VLDL particles in the Polynesian participants. Each mmol/L increase in VLDL TG was significantly associated with gout in the presence of HU in Europeans, with a similar trend in Polynesians (OR=7.61, P=0.011 and 2.84, P=0.069, respectively). The total adjusted apo B showed negative association with HU and positive association with risk of gout in NZ Polynesians.
Mendelian Randomization provided evidence for causal association of TG in raising serum urate levels in combined ARIC and FHS European males only (βObservational=0.012 mmol/L, P=1.72×10-16; βMendelian Randomization=0.021 mmol/L, P=0.002, Pcorrected=0.012). However, in vice versa analysis, no evidence was observed for a direct causal association of serum urate with TG concentration. Among individually genotyped the T-allele of rs670 (Apo A-I) increased gout risk (OR meta=1.53, Pmeta=4.88×10-6) and the G-allele of rs5128 decreased the gout risk (OR meta=0.86, Pmeta=0.025) in combined Polynesians only.
When tested for possible gene-environment interaction, the T-allele of rs2544390 SNP of LRP2 was associated with increased risk of gout in the combined Polynesians (OR=1.20, P=0.009), along with evidence for non-additive interaction of this locus with any alcohol intake to influence the risk of gout (PInteraction=0.001) in this population set. Any alcohol intake was associated with a 4.18-fold increased risk in the CC genotype group (P=6.6x10-5), compared with a 1.14-fold increased risk in the CT/TT genotype group (P=0.40). These effects were not observed in European subjects.
Collectively, causal role of TG and its associated genes in increasing gout risk in the presence of HU. Also, alcohol consumption, as potential risk factor, has been identified to interact with a protective LRP2 genotype for increasing the gout risk

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.
