Altmetrics in Library and Information Science: coverage of sources and use of social media by authors
Get PDFAltmetrics is a movement that aims to capture new and previously invisible types of impact of scholarly publications on social web platforms such as news sites, Wikipedia, blogs, microblogs, social bookmarking tools and online reference managers. This thesis aimtries to explore the suitability and reliability of two altmetrics resources: Mendeley, a social reference manager website, and Wikipedia, a free online encyclopedia, written collaboratively by the people who use it. At present, Wikipedia is the largest online encyclopedia.
The main objectives of this thesis are to explore the use of reference management software and Wikipedia to estimate the readership of academic literature and to compare the evolution in the coverage of LIS literature by altmetric sources and by citation indexes.
To reach these objectives, three different studies were designed. The general method to achive toobtain the initial data set was to search is that we used the Social Sciences Citation Index to retrieve articles and reviews published and indexed in the category “Information Science & Library Science”. Each record was then searched in Mendeley to obtain the number of bookmarks of the paper and the academic status of the users. Additonally, we performed a fifteen-month longitudinal study of the evolution of bookmarks in Mendeley. Afterwards, we searched for each of these articles in Wikipedia, and retrieved all the entries in which they were cited.
The Results results of these studies show that the correlation between bookmarks and citations was moderate and the overlap between the most frequently bookmarked and the most frequently cited papers increased over time. A significant share of the bookmarks were made by students and professionals, although the shares of bookmarks made by different categories of users changed as time went by. Reviews were bookmarked more frequently than articles, and papers in English had more bookmarks than papers in any other language.
Also results reveal severe limitations in the use of Wikipedia citations for research evaluation. Lack of standardization and incompleteness of Wikipedia references make it difficult to retrieve them. The number of Wikipedia citations is very low, A significant number of references are cited in biographical entries about the authors of the articles, resulting in a phenomenon of accumulated advantage. Nearly one-third of the Wikipedia citations link to an open access source, although this result is probably an underestimate of open access availability, given the incompleteness of Wikipedia citations.Altmetrics es un movimiento que tiene como objetivo capturar nuevos tipos de impacto, antes invisibles, de las publicaciones académicas en las plataformas de la web social, tales como sitios de noticias, Wikiped ia, blogs, microblogs, herramientas de marcadores sociales y gestores de referencias en línea. Esta tesis pretende explorar la pertinencia y fiabilidad de dos recursos altmétricos: Mendeley, un sitio web de gestión de referencia social, y Wikipedia, una enciclopedia online gratuita escrita en colaboración por las personas que la utilizan. Actualmente, Wikipedia es la mayor enciclopedia en línea. Los principales objetivos de esta tesis son investigar el uso del software de gestión de referencia y de Wikipedia para estimar el número de lectores de literatura académica y comparar la evolución en la cobertura de la literatura de Ciencias de la Información y Biblioteconomía (Library and Information Science, por sus siglas en inglés), según fuentes altmétricas y por índices de citas.
Para alcanzar estos objetivos, se diseñaron tres estudios diferentes. El método general para acceder al conjunto de datos consistía en utilizar el Social Sciences Citation Index para recuperar revisiones y artículos publicados e indexados en la categoría «Information Science & Library Science». Se buscó cada registro en Mendeley para obtener el número de marcadores del documento y el estatus académico de los usuarios. De manera adicional, realizamos un estudio longitudinal durante quince meses para estudiar la evoluci ón en el número de marcadores. Posteriormente, buscamos cada uno de estos artículos en Wikipedia y recuperamos todas las entradas en las que fueron citados.
Los resultados de estos estudios muestran que la correlación entre los marcadores y las citas era moderada y la coincidencia entre los documentos guardados en marcadores con más frecuencia y los más citados aumentó con el tiempo. Una parte significativa de los marcadores los habían hecho estudiantes y profesionales, aunque el número de marcadores hechos por diferentes categorías de usuarios cambiaron con el paso del tiempo. Las revisiones se guardaban en marcadores con más frecuencia que los artículos, y los documentos en inglés tenían más marcadores que los documentos en cualquier otro idioma.
Los resultados también revelan severas limitaciones en el uso de citas de Wikipedia para la evaluación de investigación. La falta de estandarización y el carácter incompleto de las referencias de Wikipedia dificultan su recuperación. El número de citas de Wikipedia es muy bajo, y un número significativo de referencias se citan en las entradas biográficas dedicadas a los autores de los artículos, lo que supone una ventaja acumulada. Cerca de un tercio de las citas de Wikipedia se vinculan a una fuente de acceso abierto, aunque probablemente este resultado sea una subestimación de la disponibilidad de acceso a estas fuentes, dado que las citas de Wikipedia están incompletas
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

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.
