Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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
Abstract 2072: Combination of CDODA-Me, a glycyrrhetinic acid derivative, and Erlotinib overcomes chemo-resistance in NSCLC PDX spheroids and 3D bio-printed cells
Abstract
Patient-derived Xenografts (PDXs) are considered as relevant preclinical model for anticancer drug development due to original recapitulation of patient genetic profile, gene expression patterns and tissue histology. In this study, we investigated combination efficacy of CDODA-Me (Methyl 2-cyano-3,11-dioxo-18-olean-1,12-dien-30-oate) and TKI inhibitor Erlotinib (ERL) against Lung NSCLC PDX spheroids and 3D bio-printed PDX cells. NSCLC PDX cells (EGFR T790M mutants) were obtained from Dr. Rishi’s Laboratory. PDX spheroids were grown in DMEM/ F12 media supplemented with L-glutamine, B27 supplement, recombinant human epidermal growth factor (EGF) and recombinant human basic fibroblast growth factor (bFGF). Spheroids were treated with CDODA-Me, ERL alone and in combination. Cell viability was measured by MTT assay. Western blot analysis was used to study the modulation of Bcl-xL, MDR1 and ABCG2 in treated PDX spheroids. For 3D bio-printing of PDX cells, hydrogels were prepared by partial cross-linking of sodium alginate (4.5% w/v) and gelatin (1% w/v) mixture with 40mM CaCl2 solution. PDX Cells were mixed with partially cross-linked hydrogel and printed with Inkredible 3D bio-printer (CELLINK, Sweden). Bio-printed scaffolds were fully cross-linked by 160 mM CaCl2 solution and then incubated overnight with cell culture media. The scaffolds were treated with CDODA-Me and ERL alone and in combination. After 48 h cell viabilities were determined by live/dead assay using fluorescence microscopy.
MTT assay showed that approximately 65% and 74% viability was observed at 10 µM ERL and 2.5 µM CDODA-Me respectively. Decreased spheroid cell viability was observed in ERL and CDODA-Me combination treatment. Our western blot studies showed down-regulation of Bcl-xL, MDR1 and ABCG2 in combination group. Further, 81.04 ± 5.65, 78.65 ± 3.98 and 74.35 ± 4.24 percent viable PDX cells were observed in the bio-printed scaffolds after 48, 72 and 96 h respectively. Higher percentage of dead cells (52.62 ± 1.66) were found in the combination group than CDODA-Me (28.39 ± 1.60) and ERL (29.62 ± 4.91) alone.
In conclusion, CDODA-Me in combination with ERL was found to be effective against human lung PDX spheroids and bio-printed PDX cells by decreasing the cell viability and overcoming drug resistance. Partially cross-linked sodium alginate-gelatin hydrogel enhances the possibility of PDX cell bio-printing with high cell survival rate. CDODA-Me can be considered as an effective neo-adjuvant to improve ERL efficacy in human NSCLC.

Author Under Sail The Imagination of Jack London, 1893-1902
In 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.
