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

Archaeology and Linguistics: Pomoan Prehistory as Viewed from Northern Sonoma County, California
Get PDFThe present paper, then, compares archaeological data from the Warm Springs Dam Project in northern Sonoma County (Fig. 1) with various linguistically derived reconstructions of Pomoan prehistoryin an attempt to determine the time-depth of Pomoan presence in the area. The paper argues for the necessity of such a "combined approach" and examines the requirements and assumptions inherent in it. In so doing, what follows can be seen as a test case of at least one way in which culture process may be elaborated. Two cultural breaks are present in the Warm Springs sequence, one of which seems best explained by the influx or impingement of Pomoan-speaking peoples and one which can be explained in terms of in situ functional reorientation, perhaps linked with social intensification

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
AN ARCHAEOLOGICAL INVESTIGATION OF THE MT. HICKS OBSIDIAN SOURCE, MINERAL COUNTY, NEVADA
No full textPrevious studies of obsidian sources in the western Great Basin have identified a similar pattern of use through time, though varying somewhat in scope, methodology, and conclusions. A distributional or "non-site" archaeological survey strategy was adopted to investigate the Mt. Hicks obsidian source. Spatial associations of artifacts were recorded and samples collected for analysis. In addition to techno-morphological assessment, select obsidian artifacts were subjected to obsidian hydration analysis. Results of these analyses indicate that the Mt. Hicks production curve broadly resembles that of other western Great Basin obsidian sources, but when examined in detail all differ from one another in significant ways. Results also suggest that some explanations presented to explain the shape of production curves seem inadequate, and that general trends in flaked stone use through time meet theoretical expectations
