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
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
Análisis de los principales factores de riesgo que están incidiendo en la presencia de Dislipidemias en los pacientes atendidos en el centro médico de la academia naval “Almirante Illingworth” durante el año 2012
Get PDFpdfEl presente estudio propone analizar los principales factores de
riesgos que están incidiendo en la presencia de dislipidemias que
padece los trabajadores, con el propósito de atenuarlos para que
no lleguen a sufrir problemas cardiovasculares. Esta
investigación se realizó en el centro de salud de la ANAI,
localizada al noroeste (Parroquia Tarqui) de la ciudad de
Guayaquil, Av. José Gómez Gault (Km 8 ½ vía Daule).Su
objetivo fue analizar los principales factores de riesgo que están
incidiendo en la presencia de Dislipidemias en los pacientes
atendidos en dicho centro médico durante el año 2012,
igualmente se determinó la frecuencia de aparición de la
enfermedad mediante las concentraciones de lípido y
lipoproteínas en sangre, se estableció la relación existente entre
el estado nutricional y se evaluó la incidencia de los hábitos
Alimentarios en la presencia de dislipidemias en los trabajadores
atendidos en el centro médico. El tipo de investigación es
Aplicada, transversal descriptiva, explicativa, de campo no
experimental. Se trabajó con la población en su totalidad Como
procedimiento del estudio se obtuvieron datos de las medidas
antropométricas y IMC, se extrajeron muestras de sangre de los
trabajadores por punción venosa periférica para identificar los
niveles de dislipidemias (parámetros bioquímicos). Como parte
de los resultados obtenidos se pudo detectar la presencia de
Dilispidemias en alrededor de un 40% en los trabajadores objeto
de estudio, considerándose un nivel de prevalencia alto y entre
los factores de riesgos tuvieron correlaciones positiva con la
obesidad, el sedentarismo y el consumo de grasas saturadas. Se
establecieron medidas a tomar para la disminución y control de
la prevalencia de la enfermedad estudiada en nuestro proceso
investigativo. Se llegaron a conclusiones y recomendacionesThe present study aims to analyze the main risk factors that are
affecting the presence of dyslipidemia suffering workers, in
order to reduce them so they do not suffer cardiovascular
problems. This research was conducted at the health center
ANAI, located northwest (Tarqui parish) of the city of
Guayaquil, Av José Gómez Gault (8 ½ Km via Duale). Their
main objective was to analyze the risk factors that are
influencing the presence of Dyslipidemia in patients treated in
this facility during the year 2012, also the frequency of
occurrence of the disease was determined by the concentrations
of lipid and lipoproteins in the blood, the relationship between
nutritional status was established and evaluated the incidence of
Eating habits in the presence of dyslipidemia in workers treated
at the medical center. The Applied research is descriptive crosssectional
explanatory, non-experimental field. We worked with
the population as a whole procedure of the study data and
anthropometric measures were obtained BMI, blood samples of
workers were extracted by peripheral venipuncture to identify
levels of dyslipidemia (biochemical parameters). As part of the
results obtained could be detected in the presence of
Dilispidemias about 40% for workers under study, considering a
level between high prevalence and risk factors had positive
correlations with obesity, sedentary lifestyle and consumption
saturated fat. Measures to take to reduce and control the
prevalence of the disease studied in our research process were
established. They reached conclusions and recommendation

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
Seroprevalencia de herpes tipo 1 y 2 y factores de riesgo en pacientes adultos de la clínica Ochoa del cantón el Empalme, provincia del Guayas, periodo 2012. Propuesta de medidas preventivas
Get PDFpdfObjetivo. Determinar la seroprevalencia positiva de los virus del herpes tipo 1-2, y factores de riesgo en pacientes mayores de 18 años, atendidos en la Clínica Ochoa del Cantón El Empalme, Provincia del Guayas.
Materiales y métodos. Estudio de tipo descriptivo transversal, que incluyó a nuevos pacientes mayores de 18 años que asistieron a la Clínica Ochoa, entre enero y junio del 2012. Todos los participantes proporcionaron su consentimiento informado para responder un cuestionario sociodemográfico y de vida sexual, y permitir la toma de una muestra sanguínea. La presencia de anticuerpos contra los virus herpes tipo 1-2 en los pacientes se realizaron por la técnica de International Inmune Diagnostics HSV 1-2 IgM e International Inmune Diagnostics HSV 1-2 IgG; las asociaciones entre estos resultados y los datos de la encuesta se analizaron estadísticamente, de manera cruda y ajustada, utilizando el software Epi Info V. 3.5.3..
Resultados. Del total de pacientes (315) incluidos en el estudio, 67 son seropositivos para IgG tipo 2 lo que representa un porcentaje de 21,26%; mayor porcentaje se encuentra en la Provincia del Guayas (46 muestras positivas / 68,66%), mayor seroprevalencia de herpes tipo 2 positivo IgG se encuentra en edades de 33 a 37 años (10 muestras positivas / 14,93%); la seroprevalencia de herpes tipo 2 IgG en mujeres es 42 muestras positivas (62,69%), mientras en hombres existen 25 muestras positivas (37,31%) por tanto la razón hombre mujer es 1,6:1 (por cada hombre : 1,6 mujeres están infectadas).
Conclusiones. Los hallazgos observados determinan que la seroprevalencia positiva para el herpes genital es de 21,26%, la mayor seroprevalencia positiva para IgG tipo 2 se encuentra en los grupos de edades de 33 a 37 años, población sexualmente activa, lo que aumenta el riesgo de transmisión del virus y por ende el incremento del herpes genital. El porcentaje de seroprevalencia positiva para IgG del herpes tipo 1-2 es muy elevado para las
personas que no utilizan preservativo en las relaciones sexuales o lo hacen muy ocasionalmente.
Palabras clave: Seroprevalencia; virus del herpes tipo 1-2; herpes genital; HSV 1-2 IgM; HSV 1-2 IgG; Guayas.Objective. Positively determine the seroprevalence of herpes virus type 1-2, and risk factors in patients older than 18 years, served in the "Clinical Ochoa"; El Empalme City; Guayas, Province.
Materials and methods. Transversal descriptive study, which included new patients over 18 who attended the "Clinica Ochoa", between January and June 2012. All participants provided informed consent to answer a sociodemographic questionnaire and sexual life, and allow the collection of a blood sample. The presence of antibodies against herpes virus type 1-2 patients were performed by the technique of International Immune Diagnostics HSV IgM 1-2 and 1-2 International Immune Diagnostics HSV IgG, the associations between these results and the survey data were analyzed statistically, so crude and adjusted, using the Epi Info software V. 3.5.3.
Results. Of all the patients (315) included in the study, 67 were seropositive for IgG type 2 representing a percentage of 21.26%, the highest percentage is in the province of Guayas (46 positive samples / 68.66%), higher prevalence of type 2 herpes IGG is positive at ages 33 to 37 years (10 positive samples / 14.93%) seroprevalence type 2 herpes in women IgG positive samples is 42 (62.69%), while in men there are 25 positive samples (37.31%) by both male female ratio is 1.6 / 1 (for every man / women are infected 1.6)
Conclusions. The findings determined that the seroprevalence observed positive for genital herpes is 21.26%, the highest seroprevalence IgG positive type 2 is in the age group of 33-37 years, sexually active population, which increases the risk of virus transmission and therefore increased genital herpes. The percentage of positive seroprevalence of IgG herpes type 1-2 is very high for people who do not use condoms during sex or do it very occasionally.
