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
Novel technique for removal of persistent subretinal fluid following nondrain retinal detachment surgery
No full textThis manuscript describes a case of successful reattachment of a macular-off retinal detachment following optical coherence tomography-guided internal drainage of retained subretinal fluid following a nondrain method. To date, there has not been any documented treatment option for this common phenomenon. This novel technique describes a method to remove such fluid and successfully appose the retina to the retinal pigment epithelial layer.This manuscript describes a case of successful reattachment of a macular-off retinal detachment following optical coherence tomography-guided internal drainage of retained subretinal fluid following a nondrain method.

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

No full textFamily portraits. Negative scan.In 1922, Kinso Ninomiya opened the Ninomiya Studio in Little Tokyo, Los Angeles. Due to Executive Order 9066 in 1942, the studio was forced to close but was reopened by Kinso and his son, Elwin Ichiro, in 1949. The studio operated in Little Tokyo until its final closing in 1986. The Ninomiya Studio Collection captures slices of Japanese American life in Los Angeles from the 1950s through the 1980s. The collection contains formal portraiture and candid photography in black and white and color as well as commercial photography for local businesses and reproductions of older photographs. The negatives come in a variety of sizes, including 8 x 10 inch negatives and panoramic negatives on Cirkut film. Each negative scanned has been selected out of multiple negatives and prints from a set. The title of the negative scan reflects the purchaser's name
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
Prevalencia de la infección por Helicobacter pylori en pacientes sintomáticos atendidos en consulta externa en el Hospital I Octavio Mongrut Muñoz-RAS-EsSalud periodo 2007-2010.
Full text linkBEVILACQUA Wong, Roger Augusto. Prevalencia de la infección por Helicobacter pylori en pacientes sintomáticos atendidos en consulta externa en el Hospital I Octavio Mongrut Muñoz-RAS-EsSalud periodo 2007-2010. Trabajo de Investigación (Especialista en Medicina Interna). Lima, Perú: Universidad Nacional Mayor de San Marcos, Facultad de Medicina Humana, Escuela de Post-Grado, 2014. 45 h.Objetivo: Determinar la prevalencia de Helicobacter pylori en pacientes sintomáticos gástricos que acuden a la Consulta externa del Hospital I Octavio Mongrut Muñoz, a través de la prueba del Test de aliento. Planteamiento del Problema: La Organización Mundial de la Salud ha considerado al Helicobacter pylori como carcinógeno Tipo I. Esto no significa que esta bacteria produzca sustancias carcinogénicas o mutagénicas, sino que como consecuencia de una inflamación crónica y progresiva de la mucosa gástrica, lleva a la gastritis atrófica, entidad considerada como una condición precancerosa. Material y Métodos: Se diseñó un estudio Observacional, Descriptivo y Longitudinal. El estudio se llevó a cabo en el Hospital I Octavio Mongrut Muñoz (HIOMM) que pertenece a la Red Asistencial Sabogal (RAS) de (EsSALUD); en pacientes a los cuales se les solicitó la prueba del Test de Aliento en el período comprendido entre Enero a Diciembre de los años 2007 al 2010. Resultados: La prevalencia de la infección por Hp. fue de 63.7%, 61.89%, 59.68% y 69.26% entre los años 2007 al 2010 respectivamente. Conclusión: La prevalencia encontrada se encuentra por encima de países desarrollados y en concordancia con la prevalencia en Latinoamérica. No encontrándose diferencias estadísticas significativas en relación al grupo etáreo y sexo con los estudios a nivel de Latinoamérica
