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
Actividad física y el Índice de Masa Corporal en alumnado de Educación Física
Get PDFIn the present study we delve into the importance of physical activity in the school context since it favors the improvement of health. The objective of this study was to determine the relationship between physical activity and the Body Mass Index in students aged 10 to 13 years of the National College of Application of the National University Hermilio Valdizán. The study was descriptive with a causal correlational design, the sample included 121 students, the data collected was through a questionnaire and BMI form. Finding as a result that the majority of students surveyed show a normal BMI (18.50 to 24.99) according to age, weight and height, where it is stated that there is agreement with the practice of some physical activity, corroborated by the calculated value of the Chi square test. equal to 8.37 which is greater than the critical value of 7.81. Which leads to the conclusion that there is a significant relationship between physical activity and BMI in students from 10 to 13. Likewise, it is evident that physical activity in students is in acceptable terms in terms of type, continuity, duration and intensity, showing that they are aware of performing exercises in Physical Education hours according to the virtual strategy of learning at home, they perform aerobic exercises on their own initiative, showing a period of time to perform them and above all they feel concerned about improving their fitness for health.En el presente estudio nos adentramos a la importancia de la actividad física en el contexto escolar ya que favorece la mejora de la salud. El objetivo de este estudio fue determinar la relación que existe entre la actividad física y el Índice de Masa Corporal en estudiantes de 10 a 13 años del Colegio Nacional de Aplicación de la Universidad Nacional Hermilio Valdizán. El estudio fue de tipo descriptivo con un diseño correlacional causal, la muestra incluyó 121 estudiantes, los datos recopilados fueron a través de un cuestionario y ficha de IMC. Encontrando como resultado que, la mayoría de estudiantes encuestados muestran un IMC normal (18.50 a 24.99) según edad, peso y talla, donde se manifiesta que existe concordancia con la práctica de alguna actividad física, corroborado por el valor calculado de la prueba Chi cuadrado igual a 8.37 que es mayor al valor crítico de 7.81. Lo cual lleva a la conclusión de que, sí existe relación significativa entre la actividad física y el IMC en estudiantes de 10 a 13. Asimismo, se evidencia que la actividad física en los estudiantes se encuentra en términos aceptables en lo que respecta al tipo, continuidad, duración e intensidad, mostrando que son conscientes en realizar ejercicios en horas de Educación Física según la estrategia virtual de aprendo en casa, realizan ejercicios aeróbicos por iniciativa propia, mostrando un periodo de tiempo para realizarlos y sobre todo se sienten preocupados en mejorar su condición física para la salud
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
Promoción de hábitos saludables, una propuesta de intervención mediante talleres de bicicleta en alumnado de educación física
No full textIn this work we delve into the importance of active bicycle travel in the school
context as it contributes to improve the levels of physical fitness for health. The
purpose was to determine to what extent the use of bicycles influences the
improvement of healthy life habits in high school students of the National School of
Application of the Hermilio Valdizán National University. An applied research of
quasi-experimental design was developed, with the participation of 71 students of
the VI cycle of secondary education. The results show that, with the use of the
bicycle, healthy life habits were positively influenced, they know adequate
environments for health and understand the importance of increasing the levels of
physical activity for a healthy physical condition. This situation is demonstrated by
the hypothesis testing that was favorable by rejecting the null hypothesis, with the
value of Z =8.74 is greater with respect to Z critical Zc = 1.64, which led to state that
the use of the bicycle positively influences the improvement of healthy lifestyle habits
in students.En este trabajo nos adentramos en la importancia del desplazamiento activo
con la bicicleta en el contexto escolar ya que contribuye a mejorar los niveles de
condición física para la salud. El propósito fue determinar en qué medida la
utilización de la bicicleta influye en la mejora de los hábitos de vida saludable en
los estudiantes de educación secundaria del Colegio Nacional de Aplicación de la
Universidad Nacional Hermilio Valdizán. Se desarrolló una investigación de tipo
aplicada de diseño cuasi experimental, participaron 71 estudiantes del VI ciclo de
educación secundaria. Los resultados evidencian que, con la utilización de la
bicicleta, los hábitos de vida saludable fueron de influencia positiva, conocen
entornos adecuados para la salud y comprenden la importancia de aumentar los
niveles de actividad física para una condición física saludable. Esta situación se
demuestra con la contrastación de hipótesis que fue favorable al rechazar la
hipótesis nula, con el valor de Z =8,74 es mayor respecto a Z crítica Zc = 1,64, en lo
que condujo a manifestar que la utilización de la bicicleta influye positivamente en
la mejora de los hábitos de vida saludable en los estudiantes
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
