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

This study analyzes emotional responses to visual stimuli using the eyetracking device, which tracks eye movements and measures visual attention. Emotions influence the perception of visual information, generating different attention patterns to positive and negative stimuli. The general objective of this study is to record and analyze emotions from data obtained through eyetracking. The methodology is based on data collection, analysis and processing. A group of 40 participants was selected, who were exposed to different visual stimuli, including both positive and negative images. Five key variables were measured: Total Fixation Duration (TFD), Average Fixation Duration (ADF), Total Number of Fixations (TNF), Number of Saccades (NS) and Average Pupil Diameter during Fixations (APD). The results indicated that negative images generated a 15.3% longer average fixation duration (TPD: 175.33 ms) compared to positive images (TPD: 168.66 ms). Regarding Total Fixation Duration (TFD), positive (117.61 ms) and negative (116.07 ms) images presented comparable means, with a difference of 1.3%. The analysis of Average Pupil Diameter during Fixations (APD) revealed that positive images generated an average pupil diameter of 3.10 mm, 10.7% larger than negative images (2.80 mm). These findings support the theory that, if significant differences exist, negative emotions provoke more intense and prolonged attention, while positive emotions, although attractive, do not generate the same need for evaluation in many cases; showing that there are differences in the aforementioned variables when presenting positive and negative stimuli. This study contributes to the understanding of the emotional process in response to visual stimuli and provides a basis for future research on the relationship between emotions and visual perception.

Resumen
Este estudio analiza las respuestas emocionales a estímulos visuales utilizando el dispositivo de seguimiento ocular eyetracking, que rastrea los movimientos oculares y mide la atención visual. Las emociones influyen en la percepción de la información visual, generando diferentes patrones de atención ante estímulos positivos y negativos. El objetivo general de este estudio es registrar y analizar las emociones a partir de datos obtenidos mediante eyetracking. La metodología se basa en la recopilación, análisis y procesamiento de datos. Se seleccionó un grupo de 40 participantes, quienes fueron expuestos a diferentes estímulos visuales, incluyendo imágenes tanto positivas como negativas. Se midieron cinco variables claves: Duración Total de las Fijaciones (DTF), Duración Promedio de las Fijaciones (DPF), Número Total de Fijaciones (NTF), Número de Sacadas (NS) y Diámetro Promedio de la Pupila durante las Fijaciones (DPPF). Los resultados indicaron que las imágenes negativas generaron un 15.3% más de duración promedio de fijación (DPF: 175.33 ms) en comparación con las imágenes positivas (DPF: 168.66 ms). En cuanto a la Duración Total de las Fijaciones (DTF), las imágenes positivas (117.61 ms) y negativas (116.07 ms) presentaron medias comparables, con una diferencia del 1.3%. El análisis del Diámetro Promedio de la Pupila durante las Fijaciones (DPPF) reveló que las imágenes positivas generaron un diámetro pupilar promedio de 3.10 mm, un 10.7% mayor que las imágenes negativas (2.80 mm). Estos hallazgos respaldan la teoría de que, si existen diferencias significativas, de que las emociones negativas provocan una atención más intensa y prolongada, mientras que las emociones positivas, aunque atractivas, no generan la misma necesidad de evaluación en muchos casos; mostrando que existen diferencias en las variables antes mencionadas al momento de presentar estímulos positivos y negativos. Este estudio contribuye al entendimiento del proceso emocional en respuesta a estímulos visuales y proporciona una base para futuras investigaciones sobre la relación entre emociones y percepción visual.

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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
