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
Bull Threshers and Bindlestiffs: Harvesting and Threshing on the North American Plains
Get PDFThomas D. Isern is Professor of History & University Distinguished Professor of History at North Dakota State University. He is the author and coauthor of six books, including Dakota Circle: Excursions on the True Plains and Custom Combining on the Great Plains.This Kansas Open Books title is funded by a grant from the National Endowment for the Humanities and the Andrew W. Mellon Foundation Humanities Open Book Program.Bull Threshers and Bindlestiffs is a panorama on a continental canvas: the Great Plains of North America, stretching from Texas to Alberta. Onto this surface the author lays the large features of regional practice in the harvesting and threshing of wheat during the days before the combined harvester harvesting with binder and header, threshing with bull thresher and steam engine. Into the picture he places the key figures who accomplished the task of gathering the grain the farm men and women, the custom threshermen, and the bindlestiffs, or itinerant laborers. Affectionately he sketches the small details of folklife that comprised the everyday work and culture of the wheat belt building shocks, loading racks, constructing stacks, pitching bundles into the separator, hauling water to the engine, drinking deep from the crockery water jug. Bull Threshers and Bindlestiffs is a profusely illustrated study of a complex, vigorous regional culture concerned with the production of wheat a culture that centered around the annual harvest and declined with the advent of the combine. This is an examination of the interaction of culture, environment, and technology with import for the fields of agricultural history and regional history. More than that, with its grassroots research, its descriptions of tools and customs, and its lavish illustrations, it is a re-creation of a proud phase of regional life previously captured only in yellowed albumen photographs
