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
Resistencia antibiótica en Acinetobacter spp. y Enterobacter cloacae complex: epidemiología, mecanismos y tratamiento
No full text[Resumo] A resistencia antibiótica, con Acinetobacter baumannii e Enterobacter cloacae complex (ECC) como microorganismos clave, constitúe unha das principais causas de morbimortalidade a nivel mundial. O estudo destas poboacións resulta esencial para desenvolver estratexias que mitiguen o impacto das infeccións na saúde pública.
Nesta Tese Doutoral analízanse dúas coleccións multicéntricas nacionais de cepas clínicas, unha de Acinetobacter spp. e outra de ECC, co propósito de determinar a súa epidemioloxía, patróns e mecanismos de resistencia antibiótica, así como de explorar a actividade de novas alternativas terapéuticas. Deste xeito, cefiderocol posicionouse como o antibiótico máis activo contra A. baumannii, seguido pola colistina, a pesar do descenso significativo na eficacia desta na última década. Sublíñase tamén a problemática relacionada co ST2, con numerosos illamentos XDR, e cunha representación destacada da OXA-23, que evidencia un cambio paradigmático na epidemioloxía de A. baumannii resistente a carbapenémicos en España. Esta resistencia, mediada na súa maioría por carbapenemasas de clase D, queda aplacada polo inhibidor LN-1-255, o cal restaura o potencial de antibióticos como imipenem ou sulbactam. Doutra banda, nesta Tese caracterízase por primeira vez a diseminación plasmídica da carbapenemasa OXA-24/40 entre illamentos de Acinetobacter no-baumannii pertencentes á colección, así como a súa propagación internacional. Finalmente, en referencia a ECC, demostrouse a asociación de VIM-1 coa redución da sensibilidade ao cefiderocol, abordando aspectos microbiolóxicos, bioquímicos e moleculares. Ademais, destácase a influencia de factores adicionais na restrición da actividade desta cefalosporina de última xeración en ECC.[Resumen] La resistencia antibiótica, con Acinetobacter baumannii y Enterobacter cloacae complex (ECC) como microorganismos clave, constituye una causa importante de morbimortalidad a nivel global.

Studying these populations is crucial for developing effective strategies to lessen the impact of the resulting infections on public health.
In this Doctoral Thesis two multicentric national collections of clinical strains, one comprising Acinetobacter spp. and the other ECC isolates, are examined to discern their epidemiology, resistance patterns and mechanisms, and to ultimately explore the activity of new therapeutic alternatives. Cefiderocol emerges as the most potent antibiotic against A. baumannii, followed by colistin, despite its notable decrease in efficacy over the past decade. Attention is drawn to the issue of ST2, characterized by numerous XDR isolates and a notable representation of OXA-23, signaling a paradigm shift in carbapenem-resistant A. baumannii epidemiology in Spain. This resistance, largely mediated by class D carbapenemases, is mitigated by the LN-1-255 inhibitor, restoring the potential of compounds like imipenem or sulbactam. On another note, in this Thesis, plasmid-mediated dissemination of the carbapenemase OXA-24/40 among isolates of Acinetobacter non-baumannii belonging to the collection is characterized for the first time, highlighting its international spread. Concerning ECC, the association of VIM-1 with diminished susceptibility to cefiderocol is demonstrated, addressing microbiological, biochemical, and molecular factors. Furthermore, emphasis is placed on the influence of additional factors restricting the activity of this latest generation cephalosporin in ECC

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.
