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
Pathogen Traffic by Dendritic Cells in Periodontitis: Links to Coronary Heart Disease
No full text99 pg.Chronic low-grade infections, such as chronic periodontitis (CP), are suspected of increasing Coronary Artery Disease (CAD) risk; however, the linking mechanisms are just emerging. Porphyromonas gingivalis (Pg), commonly implicated in CP, along with multiple other pathogens, have been associated with the pathogenesis of coronary artery disease (CAD). However, it is unclear how these pathogens travel to and invade the arteries and their precise role in the disease process. P. gingivalis is known for invading epithelial, fibroblast, endothelial and myeloid dendritic cells (mDCs). Recent in-vitro evidence has demonstrated that P. gingivalis targets DC-SIGN+ (Dendritic Cell-Specific Intercellular adhesion molecule-3-Grabbing Non-integrin) mDCs via its DC-invasin minor (mfa-1) fimbriae and uncouples dendritic cell maturation from the cytokine response, leading to intracellular bacterial persistence. Unlike epithelial and endothelial cells, mDCs are highly migratory. Thus P. gingivalis could potentially traffic to atherosclerotic plaques via mDCs. Moreover, DC-SIGN+ mDCs increase dramatically in unstable atherosclerotic plaques, as observed in gingival tissue lesions from patients with CP. Thus we hypothesize that Pg infected mDCs in CP lesions redistribute to the peripheral blood. These along with blood mDCs that pick up Pg directly in the blood, contribute to the infiltrating pool of mDCs observed in patients with CAD. The objectives of this study were to determine the frequency of blood and tissue mDCs in CP and CAD patients relative to healthy individuals. In addition, we began to establish the role of blood mDCs in dissemination of periodontal pathogens to atherosclerotic plaques. Accordingly, we examined the infection status of mDCs in gingival tissues and coronary artery atherosclerotic (ATH) plaque biopsies, as well as peripheral blood mDCs of a cohort of CP patients, with or without existing acute coronary syndrome (ACS). We initially focused on confirming that CP patients (n=26) were colonized by P. gingivalis, by analysis of the oral biofilm (i.e. subgingival dental plaque) by qRT-PCR of 16s rDNA; followed by genomic blast sequence analysis (qRT-PCR/GBS) of the 197 bp PCR-amplified product. The results indicate a 44% subgingival colonization rate with P. gingivalis in CP patients. Gingival biopsies from the Pg-infected CP patients were then analyzed by immunofluorescence-laser confocal microscopy (IF-LCM), focusing on colocalization of the DC-invasin of P. gingivalis, mfa-1 (AEZ? Mfa1), and on its target receptor on mDCs, DC-SIGN. The results reveal mfa-1 + DC-SIGN+ mDCs in CP lesions. These Pg "infected" DC-SIGN+ mDCs were also observed in post-mortem coronary artery ATH plaques. The presumed conduit for transfer of Pg to ATH plaques, migratory CD19- DC-SIGN+ CD1c+ mDCs were then isolated from peripheral blood of CP and ACS/CP patients and analyzed by IF-LCM. The results confirm the presence of mfa-1+ P. gingivalis infected blood mDCs in the blood of CP and ACS/CP patients. The estimated CFUs (eCFUs) of Pg in blood mDCs equaled 1.32 (+ 1.21) X 105. Other pathogens identified in blood mDCs included Pseudomonas spp., Moraxella catarrhalis, Klebsiella pneumonia, among other species. Overall, the findings support blood mDCs as a conduit for transport of infectious agents from gingival tissues to coronary arteries and possibly other distant sites in the human body.Advisor(s): Cutler, Christopher W..

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

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.
