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
Shock index as a predictor of mortality in trauma patients during the first 72 hours
Get PDFIntroducción: El trauma es un problema de salud pública que afecta a millones de personas cada año, generando una alta tasa de discapacidad y mortalidad en pacientes jóvenes, por tal motivo el uso de herramientas pronosticas como el índice de shock (IS) permitiría una atención oportuna y eficaz de los servicios de urgencias, al identificar parámetros de hipoperfusión tisular y desenlaces clínicos
Métodos: Se realizó un estudio descriptivo observacional de corte transversal, en pacientes víctimas de trauma que ingresaron desde enero de 2019 a diciembre de 2019 en un hospital Universitario de Colombia. Se evaluaron las variables y se determinó el resultado según el índice de shock, generando una variable dicotómica con dos grupos: grupo A, con un índice menor de 0,9, y grupo B, con uno mayor de 0,9. Se hizo un análisis univariado.
Resultados: Se analizaron 180 pacientes, 56,6 % (102) presentaron IS menor de 0,9 y 43,3 % (78), mayor de 0,9. El promedio de edad para el grupo A fue 38,7 años y, para el grupo B, 30,2 años. La mortalidad a las 72 horas fue 16.6 % en grupo A y 80.7 % en el B. para un total de 44.4 %. La supervivencia a las 72 horas para el grupo A fue de 83.3 % y para el B 19.2% de un total de 55.5 %.
Conclusión: EL IS facilita la elección de tratamientos acordes al estado de gravedad, debido a que un puntaje mayor a 0.9 se asocia con mortalidad; aspecto que priorizaría la atención en urgencias por parte del personal médico, en pacientes que aparentemente están estables, pero de acuerdo con el IS tienen mal pronóstico. Los resultados sugieren que este índice puede ser útil en la predicción de resultados adversos y en definir la reanimación hídrica.Introduction: Trauma is a public health problem that affects millions of people every year, generating a high rate of disability and mortality in young patients, for this reason the use of prognostic tools such as the shock index (IS) would allow attention timely and effective emergency services by identifying tissue hypoperfusion parameters and clinical outcomes.
Methods: A descriptive, cross-sectional observational study was carried out in polytraumatized patients who were admitted from January 2019 to December 2019 in a University hospital in Colombia. The variables were evaluated, and the result was determined according to the shock index, generating a dichotomous variable with two groups: group A, with an index less than 0,9, and group B, with one greater than 0.9; a univariate analysis was done. Measures of central tendency and dispersion were calculated for continuous variables.
Results: 180 patients were analyzed, 56,6 % (102) is less than 0,9 and 43,3 % (78), greater than 0.9. The average age for group A was 38,7 years and, for group B, 30,2 years. Mortality at 72 hours was 16,6 % in group A and 80,7 % in group B. for a total of 44,4 %. Survival at 72 hours for group A was 83,3 % and for B 19,2 %, out of a total of 55,5 %.
Conclusion: SI facilitates the choice of treatments according to the state of severity, since a score greater than 0.9 is associated with mortality; aspect that would prioritize emergency care by medical personnel, in patients who are apparently stable, but according to the IS have a poor prognosis. The results suggest that this index may be useful in predicting adverse outcomes and in defining fluid resuscitation
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.
