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
Protocolo para captura de señales electromiográficas producidas por músculo uterino en gestantes para predicción de parto pretérmino
No full textThe objective of this research was to design a protocol for the capture of electrohysterographic signals, for the prediction of preterm delivery.The study was exploratory - descriptive, purposeful. For the design, a documentary review of qualitative and quantitative scientific research articles was carried out, in English, Spanish, they were consulted in sources of biomedical information with words from specialized the sauri such as MEsH and DeCS, they were consulted in databases: PubMed,Scielo, IEEE, among others. The search expressions were: Electromyography, uterine muscle and protocol. No specific protocols for uterine electrohysterography were found, which is why the publications referring to electromyography protocols in general were taken, finding a total of193 publications, of which 23 articles were selected, published between the years 2012 to 2020. For the analysis the research method called integrative review was used. Results: The protocol establishes the criteria that must be taken into account before and during the procedure, the equipment and materials required, and contraindications, to capture the record of electrohysterographic signals. Conclusion: The EHG signal capture protocol allows standardizing the procedure to obtain optimal signals for predicting preterm delivery.Objetivo: diseñar protocolo de proceso de captura de señales electrohisterográficas, para predicción de parto pretérmino. Materiales y métodos: estudio exploratorio – descriptivo, propositivo. Para el diseño se realizó revisión documental de artículos científicos investigativos de corte cualitativo y cuantitativo, en inglés y español, consultados en fuentes de información biomédica especializados como el MEsH y DeCS y en bases de datos como: PubMed, Scielo, IEEE, entre otros. Las expresiones de búsqueda fueron: electromiografía, músculo uterino y protocolo. No se encontraron protocolos específicos para electrohisterografía, por la cual se tomaron publicaciones referentes a protocolos de electromiografía en general, encontrándose un total de 193 publicaciones, de los cuales se seleccionaron 23, publicados entre 2012 y 2020. Para el análisis se utilizó el método de investigación denominado revisión integradora. Resultados: el protocolo plantea criterios que deben tenerse en cuenta antes y durante el procedimiento, equipos y materiales requeridos y contraindicaciones, para la captura de registro de señales electrohisterográficas. Conclusión: los protocolos de atención en salud son fundamentales, ya que por medio de ellos se estandarizan los procesos que se deben seguir en la captura de señales, minimizando las posibles complicaciones durante y después del procedimiento, en beneficio del binomio madre-hijo
Mortalidade materna e infantil entre localidades em Bogotá D.C. por tercis de pobreza, 2011-2021
No full textObjective: to analyze maternal and child mortality among the localities of Bogotá D.C. according to poverty tertiles for the period 2011-2021. Methodology: longitudinal ecological design with retrospective information. Mortality records were taken from the Bogotá Health Observatory; monetary poverty data corresponds to the measurements of the Bogotá D.C. Multipurpose Survey. An analysis of trend behavior was performed using Jointpoint regression. The Relative Index of Inequality (RII) was used to measure health outcome inequality among localities according to poverty tertiles. Results: health indicators behave differently among the groupings of localities by poverty tertiles. Inequalities in the behavior of under-5 mortality by poverty tertiles were identified in Bogotá D.C., which persisted throughout the observation period. In the case of perinatal mortality, infant mortality, and maternal mortality, inequalities were present only in some years of the 2011-2021 period. Conclusions: the results of this study provide a better understanding of the dynamics of maternal and infant health inequalities, where health professionals can play an active role in the formulation of health policies and the promotion of a comprehensive, integrated, and equitable health approach.Objetivo: analizar la mortalidad materno-infantil entre las localidades de Bogotá D.C. según terciles de pobreza para el periodo 2011-2021. Metodología: diseño ecológico longitudinal con información retrospectiva. Los indicadores de salud se tomaron del Observatorio de Salud de Bogotá; los datos de pobreza monetaria corresponden a las mediciones de la Encuesta Multipropósito de Bogotá D.C. Se realizó un análisis del comportamiento de las tendencias mediante la regresión de Jointpoint. Para la medición de la desigualdad de los resultados en salud entre las localidades según terciles de pobreza, se utilizó el Índice Relativo de Desigualdad (IRD). Resultados: los indicadores de salud se comportan de manera distinta entre las agrupaciones de localidades por terciles de pobreza. Se identificaron desigualdades en el comportamiento de la mortalidad en menores de 5 años por terciles de pobreza en Bogotá D.C, los cuales se mantuvieron a lo largo del periodo de observación. Para el caso de la mortalidad perinatal, mortalidad infantil y mortalidad materna, se presentaron desigualdades para algunos años del periodo 2011-2021. Conclusiones: los resultados de este estudio permiten entender las dinámicas de las desigualdades en salud materno-infantil, a partir de lo cual, los profesionales de salud pueden desempeñar un rol activo en la formulación de políticas de salud y en la promoción de un enfoque integral, integrado y equitativo en salud.Objetivo: analisar a mortalidade materna e infantil entre as localidades de Bogotá D.C. de acordo com os tercis de pobreza para o período 2011-2021.

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
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
