The relationship between body image and anthropometric measurements among adolescent girls during menstrual and non-menstrualtime periods: a cross-sectional study.
No full textIntroduction: In recent studies, it has been suggested that anxiety about body image increases during menstruation in adolescents and may affect nutritional status. This study aimed to evaluate the relationship between adolescents' body images, body perceptions and anthropometric measurements during menstrual and non-menstrual time periods.
Methods: This cross-sectional study was carried out in a private high school between September-November 2021. Participants were adolescent girls aged 14-18. The questionnaire included information about menstruation, anthropometric measurements, and the Body Cathexis Scale (BCS) and Stunkard Figure Rating Scale.
Results: The mean age (total=291) was 15.9(1.13) years, body mass index (BMI) was 21.13(3.33) kg/m2, waist circumference was 70.48(8.87) cm and the BCS was 97.39(24.59). The majority of students have normal BMI. However, according to waist circumference 28.5% of the them were obese (≥ 90th percentile). Difference between actual BMIs and body image in the menstrual period was significant (p<0.001), the agreement with each other was slight (K=0.172). There was a significant difference (p<0.001) between actual BMIs and body image in the non-menstrual period and the agreement with each other was moderate (K=0.474). During non-menstrual periods, 79.7% of students with normal BMI perceived their body images as normal, and 70.5% of overweight students perceived as overweight.
Conclusions: Since the menstruation is a period in which body image is perceived differently than it is, special consideration of adolescent girls in terms for eating disorders should be encouraged.Introducción: En estudios recientes, se ha sugerido que la ansiedad por la imagen corporal aumenta durante la menstruación en las adolescentes y puede afectar el estado nutricional. Este estudio tuvo como objetivo evaluar la relación entre las imágenes corporales, las percepciones corporales y las medidas antropométricas de adolescentes durante los períodos menstruales y no menstruales.
Metodología: Este estudio transversal se realizó en un colegio privado entre septiembre-noviembre de 2021. Las participantes eran chicas adolescentes de 14 a 18 años. El cuestionario incluía información sobre la menstruación, las medidas antropométricas y la Escala de catexis corporal (BCS) y la Escala de calificación de la figura de Stunkard.
Resultados: La edad media (total=291) fue de 15,9(1,13) años, el índice de masa corporal (IMC) de 21,13(3,33) kg/m2, el perímetro de cintura de 70,48(8,87) cm y el BCS de 97,39(24,59). La mayoría de los estudiantes tienen un IMC normal. Sin embargo, según el perímetro de cintura el 28,5% de ellas eran obesas (≥ percentil 90). La diferencia entre los IMC reales y la imagen corporal en el período menstrual fue significativa (p<0.001), la concordancia entre ellas fue leve (K=0,172). Hubo una diferencia significativa (p<0.001) entre los IMC reales y la imagen corporal en el período no menstrual y la concordancia entre ellas fue moderada (K=0,474).Durante los períodos no menstruales, el 79,7% de las estudiantes con IMC normal percibían su imagen corporal como normal y el 70,5% de las estudiantes con sobrepeso percibían sobrepeso.
Conclusiones: Dado que la menstruación es un período en el que la imagen corporal se percibe diferente de lo que es, se debe fomentar la consideración especial de las adolescentes en términos de trastornos alimentarios

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
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
