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
Factores sociodemográficos y clínicos asociados a la eficacia de la ventilación no invasiva en pacientes ingresados con neumonía por SARS-CoV-2 al área de emergencia del Hospital Militar Central en el período de marzo a diciembre del 2020
Full text linkEste estudio se centra en identificar los factores sociodemográficos y clínicos asociados a la eficacia de la ventilación no invasiva en pacientes con neumonía por SARS-CoV-2 ingresados en el área de emergencia del Hospital Militar Central durante el periodo de marzo a diciembre de 2020. Objetivo general: Determinar los factores sociodemográficos y clínicos que influyen en la eficacia de la ventilación no invasiva en pacientes con neumonía por SARS-CoV-2. Objetivos específicos: Evaluar la asociación de factores sociodemográficos (edad, sexo, estado civil) con la eficacia de la ventilación no invasiva. Analizar la relación de factores clínicos (antecedentes epidemiológicos, comorbilidades y estado de salud al ingreso) con la eficacia de la ventilación no invasiva. Variables: Variable dependiente: Eficacia de la ventilación no invasiva. Variables independientes: Factores sociodemográficos y clínicos. Diseño metodológico: El estudio es no experimental, ya que no se manipularán variables. Es correlacional, enfocándose en la relación entre las variables de interés, y transversal, ya que se realizará un análisis único de la muestra sin seguimiento posterior. Población y muestra: La población de estudio comprende a los pacientes adultos que ingresaron al área de emergencia del Hospital Militar Central con neumonía por SARS-CoV-2. La muestra estará constituida por 339 pacientes que recibieron ventilación no invasiva durante el periodo de investigación. Técnica e Instrumentos: Se utilizará la observación directa para la recolección de datos a través del sistema de información del hospital. Se aplicará una ficha de registro de datos que incluirá ítems de filiación y datos clínicos. La información se organizará en hojas de cálculo de Excel para su posterior análisis, que se realizará utilizando el software SPSS versión 25. Se emplearán pruebas estadísticas no paramétricas para el análisis inferencial, presentando los resultados en forma de tablas y gráficos para describir los hallazgosSubmitted by Mónica Barrueto ([email protected]) on 2024-05-08T20:55:05Z

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
Hábitos tabáquicos en el personal de enfermería
No full textEsta tesina se elaboró con el objetivo de conocer si el hábito de fumar interfiere en el desempeño laboral de los enfermeros de Clínica Médica del Hospital Del Carmen. Para ello se incluyó material de diferentes fuentes y autores con la idea de tener una amplia información que sirva como marco teórico para la investigación.
A pesar de los esfuerzos que se han realizado en los últimos años, como así también la implementación de políticas de espacios libres de humo, cesación tabáquica, y de lo mucho que se ha profundizado en los aspectos relacionados con la prevención de esta enfermedad, en la actualidad no ha sido posible eliminar esa actividad de lugares públicos, los cuales deberían ser modelo. Por ese motivo se considera que es importante seguir planteando trabajos o acciones que tenga como objetivo revertir o al menos concientizar respecto al tema.
Para ello, se identificó a los enfermeros fumadores que componen la muestra, describiendo las características emocionales que estos manifiestan ante la abstinencia transitoria de fumar, de acuerdo a las actividades laborales que realizan.Fil: Puita, Erica.

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
