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
Segmentación RFM de clientes de un programa de fidelización en una empresa retail con el algoritmo de análisis clúster PAM
Full text linkUniversidad Nacional Agraria La Molina. Facultad de Economía y Planificación. Departamento Académico de Estadística e InformáticaLas empresas enfrentan el desafío de manejar gran cantidad de datos, aprovecharlos y transformarlos en información valiosa que generen insights relevantes para toma de decisiones y alinear la estrategia. Una de las técnicas más utilizadas ha sido el análisis de agrupamiento en biología, ingeniería, psicología, y otras disciplinas, pero donde habría resultado de mayor utilidad es en los negocios, específicamente en investigación de mercados, desde la segmentación de clientes, identificación de hábitos de compra y otros. Así, la empresa de retail de la que se trata en este trabajo, opera bajo un enfoque centrado en el cliente, por lo cual busca mayor entendimiento del mismo, aprovechando los datos que dispone. El área de Inteligencia de Negocios es responsable del tratamiento y análisis de datos, proponiendo una segmentación RFM con un análisis clúster, que permitió agrupar a un conjunto de clientes objetivo para la empresa, para entenderlos mejor y sirvió como insumo para el programa de fidelización que la empresa lanzó. El algoritmo aplicado para el agrupamiento fue el PAM, que consiste en un proceso de partición iterativo similar al algoritmo k-means, pero que utiliza como centroide la mediana y no la media, haciendo al PAM más robusto ante valores atípicos. El algoritmo se basa en minimizar la suma de las diferencias entre una observación y la mediana. El análisis y procesamiento de datos se realizó con el software R-Studio, y se obtuvieron 3 grupos que describen como se comportan transaccionalmente los clientes objetivo de la empresa. Los segmentos fueron denominados Vip (clientes Top), Plus (clientes intermedio) y Regular (de menor rendimiento), ordenados jerárquicamente. Estos segmentos le sirvieron a la empresa para entender el comportamiento de estos clientes, sentando las bases para el programa de fidelización.Companies face the challenge of managing a large amount of data, taking advantage of it and transforming it into valuable information that generates relevant insights for decision making and aligning the strategy. One of the most used techniques has been cluster analysis in biology, engineering, psychology, and other disciplines, but where it would have been most useful is in business, specifically in market research, from customer segmentation, identification of habits shopping and others. Thus, the retail company discussed in this work operates under a customer-centric approach, which is why it seeks a better understanding of it, taking advantage of the data it has. The Business Intelligence area is responsible for the treatment and analysis of data, proposing an RFM segmentation with a cluster analysis, which allowed grouping a set of target customers for the company, to understand them better and served as input for the loyalty program that the company launched. The algorithm applied for the grouping was the PAM, which consists of an iterative partitioning process similar to the k-means algorithm, but which uses the median and not the mean as the centroid, making the PAM more robust against outliers. The algorithm is based on minimizing the sum of the differences between an observation and the median. The analysis and processing of data was carried out with the R-Studio software, and 3 groups were obtained that describe how the target customers of the company behave transactionally. The segments were called Vip (Top customers), Plus (intermediate customers) and Regular (lowest performance), arranged hierarchically. These segments helped the company to understand the behavior of these customers, laying the foundations for the loyalty program
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
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.
