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
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
Smoking during pregnancy in Argentina and Uruguay
Full text linkArgentina y Uruguay están entre los países con mayor proporción de mujeres jóvenes fumadoras. Se desconoce cuál es la proporción exacta de ellas que fuman durante el embarazo así como las características de las que dejan de fumar y las que continúan fumando durante el embarazo. Realizamos una encuesta administrada por un/a entrevistador/a a 1512 mujeres embarazadas de 18 años o mayores (796 en Argentina; 716 en Uruguay), que concurrían a control prenatal en hospitales públicos de grandes conglomerados urbanos. 44% de las mujeres en Argentina y 53% en Uruguay habían sido o eran fumadoras. Durante el embarazo, 11% de las mujeres en Argentina y 18% en Uruguay continuaron fumando. En ambos países, la proporción de mujeres que vive con fumadores, permite fumar en el hogar y regularmente o siempre se encuentra en lugares cerrados con personas que estén fumando fue 49%, 46% y 20% entre las mujeres que nunca fumaron, 67%, 60% y 32% entre las que dejaron, y 78%, 75% y 52% entre las que continuaron fumando respectivamente. El estudio confirma un importante problema de salud pública y documenta que la exposición ambiental persiste en subgrupos de mujeres, aun en aquéllas que dejaron de fumar. Es importante que el sector de salud pública provea acceso a programas efectivos para dejar de fumar durante el embarazo. Cualquier nueva intervención a desarrollar que intente tener un éxito al menos moderado y sostenible, debiera incluir componentes que actúen sobre el entorno fumador de la mujer embarazada que fuma.Argentina and Uruguay are among the countries in which a large proportion of young women smoke. The rate of smokers during pregnancy in both countries is not well known, and data on the characteristics of women who quit smoking during pregnancy compared to those who continue smoking are not available. We conducted a survey including 1512 pregnant women >18 years old (796 in Argentina; 716 in Uruguay), during antenatal visits in public hospitals of large urban regions; 44% of the women in Argentina and 53% in Uruguay had been or were regular smokers. 11% of the surveyed women in Argentina and 18% in Uruguay continued smoking during pregnancy. In both countries, the proportion of women who lived with smokers, allowed smoking at home, and were regularly or always exposed to tobacco smoke indoors, were 49%, 46% and 20% in the subgroup of women who never smoked, 67%, 60% and 32% in those who quit, and 78%, 75% and 52% in those who continued smoking, respectively. The study confirms a serious public health problem in both countries, and documents that environmental exposure persists in subgroups of women, even in those who quit smoking. It is important that the public health sector should provide access to effective programs for smoking cessation, to women who smoke during pregnancy. For the development of a new program, any intervention intending to have at least a moderate and sustainable success, it should seriously consider including components targeting the smoking environment of the pregnant women who smoke.Fil: Althabe, Fernando.

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
Por servicios de salud sexual y reproductiva amigables para adolescentes : un estudio cualitativo
Full text linkLa Salud Sexual y Reproductiva se define como “un estado general de bienestar físico,
mental y social, y no de mera ausencia de enfermedades o dolencias” (Stampar,1946). Sobre las acciones hacia adolescentes, ha sido dilemático y conflictivo el trato en
relación a la vivencia de la sexualidad y a los aspectos referidos a las decisiones de
esta población. La Conferencia Internacional de Población y Desarrollo de Naciones Unidas aborda las necesidades de la población adolescente, y recomienda la implementación de servicios específicos resaltando el derecho de los y las adolescentes “a la intimidad, confidencialidad, el respeto y el consentimiento basado en una información correcta y respetuosa de los valores culturales y las creencias religiosas” (CIPD, 1994). En marzo de 2005, se crea en Uruguay el Programa Nacional de Salud Adolescente, con el objetivo de construir una política nacional de salud integral para la adolescencia, basada en principios de universalidad, equidad, accesibilidad, territorialidad y respeto por la diversidad. En el marco de estas acciones, se crean luego los “espacios adolescentes” los cuales se presentan como un espacio diferencial de atención y promoción de la salud con especial énfasis en el enfoque de derecho y género. Este estudio pretende evaluar el funcionamiento de una selección de espacios
diferenciales destinados a adolescentes con el fin de contribuir a su desarrollo, expansión y fortalecimiento
