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
Actitudes hacia la investigación científica y estadística en estudiantes de Psicología
Full text linkCurrent university education places special emphasis on developing skills for scientific research and mastering statistics. However, despite their importance, courses in research methodology and statistics are often the most difficult and least preferred for many students. For this reason, the principal aim of this study was to analyze the relationship between attitudes towards scientific research and statistics in psychology students from a private university in Metropolitan Lima. A simple correlational non-experimental design was used. One hundred psychology students enrolled in an introductory statistics course participated (M = 21.41, SD = 4.20), who answered self-report instruments. The results showed that psychology students have favorable attitudes towards scientific research and statistics. In addition, there are certain differences in the levels of these attitudes according to previous experience in courses in research methodology and statistics. Finally, both variables correlate positively and significantly (r = .482; p < .01). It is concluded that there is an important association between attitudes towards scientific research and statistics in psychology students.La formación universitaria actual pone especial énfasis en el desarrollo de habilidades para la investigación científica y el dominio de la estadística. Sin embargo, a pesar de su importancia, los cursos de metodología de la investigación y estadística suelen ser los más difíciles y menos preferidos para muchos estudiantes. Por tal motivo, el objetivo principal de este estudio fue analizar la relación entre las actitudes hacia la investigación científica y la estadística en estudiantes de psicología de una universidad privada de Lima Metropolitana. Se empleó un diseño no experimental correlacional simple. Participaron 100 estudiantes de psicología matriculados en un curso introductorio de estadística (M = 21.41, DE = 4.20), quienes respondieron instrumentos de autoinforme. Los resultados mostraron que los estudiantes de psicología poseen actitudes favorables hacia la investigación científica y la estadística. Asimismo, existen ciertas diferencias en los niveles de estas actitudes según la experiencia previa en cursos de metodología de la investigación y estadística. Finalmente, ambas variables correlacionan de forma positiva y significativa (r = .482; p < .01). Se concluye que existe una importante asociación entre las actitudes hacia la investigación científica y la estadística en estudiantes de psicología

Happiness, positive emotions, cognitive appraisal, and coping in university students of Metropolitan Lima
Full text linkObjetivo. El objetivo principal fue examinar la influencia de la felicidad, por medio de la evaluación cognitiva y las emociones positivas, en el afrontamiento del estrés en estudiantes universitarios. Método. Participaron 352 personas, 70.2% mujeres y 29.8% hombres, con un rango de edad entre 19 y 35 años. Se realizaron modelos de ecuaciones estructurales (SEM, por sus siglas en inglés) para estimar la influencia de la felicidad en el proceso del estrés y el afrontamiento. Resultados. Los resultados mostraron correlaciones esperadas entre las variables y un buen ajuste de los modelos propuestos. La felicidad influye en la utilización de estrategias de afrontamiento adaptativas, a través de la evaluación cognitiva de desafío (β = .220; p < .001) y la experiencia de emociones positivas (β = .159; p = .001). Se concluye que la felicidad tiene un importante papel en el proceso del estrés y el afrontamiento.Objective. The main objective of this study was to examine the influence of happiness by cognitive appraisal and positive emotions on stress coping in university students. Method. 352 people participated in the study, 70.2% were women, with an age range of between 19 and 35 years. Structural Equation Models (SEM) were tested to estimate the influence of happiness in the stress process and coping. Results. The results showed expected correlations between the variables and a good fit of the proposed models. Happiness influences the use of adaptive coping strategies, through the cognitive appraisal of challenge (β = .220; p < .001) and the experience of positive emotions (β = .159; p = .001). In conclusion, happiness plays an important role in the stress and coping process.Campus San Juan de Luriganch

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
