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
Investigation of local immune responses at the maternal-fetal interface during infection with Porcine Reproductive and Respiratory Syndrome Virus
No full textPhD thesis - University of Veterinary Medicine Vienna - 2023In humans and mice, extensive research on the phenotype and function of immune cells that reside at the maternal-fetal interface has been performed with the goal to understand the complexity of reproductive immunology. In pigs, however, studies that addressed immune cell phenotypes at the maternal-fetal interface mainly focused on early gestation, whereas late gestation has not been investigated so far. In addition, the literature available so far only addressed the major lymphocyte subsets without going into much detail. Therefore, this PhD thesis aimed to establish a methodology tailored to porcine epitheliochorial placenta which would allow for the investigation of the immune cell composition in the maternal endometrium (ME) and fetal placenta (FP) separately. In the first study we performed in-depth phenotyping experiments for the characterization of natural killer cells (NK), non-conventional, and conventional T cells within maternal blood (mBld), ME, FP, and fetal spleen (fSpln). The results showed that between the investigated anatomic locations that observed NK and T cell phenotypes were considerably different. Lymphocyte subsets originating from the maternal compartments (mBld and ME) displayed highly differentiated phenotypes. Furthermore, even in the absence of any stimuli, lymphocytes isolated from the maternal compartments had a high capacity to spontaneously release interferon-gamma (IFN-γ) which reflected the high degree of NK and T cell differentiation within those anatomic sites. In the fetal compartments (FP and fSpln), mainly naive phenotypes were found. Nevertheless, also differentiated phenotypes e.g. CD2+CD8α+CD27dim/-perforin+ γδ T cells, CD27-perforin+ cytolytic T cells (CTLs), and T-bet+CD4+CD8α+CD27- Tem cells were identified in the FP. Porcine reproductive and respiratory syndrome virus (PRRSV) causes reproductive failure during late gestation. As to date, the local immune response at the maternal-fetal interface remains poorly characterized and specific literature available is sparse. Therefore, our second study aimed to investigate the phenotypic changes at the maternal-fetal interface following PRRSV infection and/or vaccination in a reproductive gilt model. A total of twenty-four gilts were included, twelve gilts were vaccinated with a modified live virus (MLV) vaccine whilst the other twelve gilts were not. During late gestation (day 84) gilts were challenged with either one of the two selected PRRSV-1 field isolates or sham-inoculated with cell culture medium. Three weeks postinfection all gilts and their litters were euthanized and two fetuses per gilt were randomly selected in order to study the local immune response in the ME and FP. In non-vaccinated gilts, infection resulted in a strong expansion of effector lymphocytes which might contribute to pathology at the maternal-fetal interface rather than confer protection. A more contained immune response was observed in the vaccinated gilts and conferred protection. Taken together, these studies provide the groundwork to further explore local immunity in utero and provide insight into local events in response to PRRSV infection. Furthermore, the same methodology could be applied to other pathogens that cause reproductive failure
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.
