Data from range-wide study of migratory connectivity of Vermivora warblers
No full textSee ReadMe.txt for detailed description of files.This collection of files provide data from a range-wide study of the migratory ecology of Vermivora warblers. Data include raw light-level data from geolocators, R code, and associated output. These data can be used to recreate analyses including:
(1) Individual nonbreeding occurrence and population-level nonbreeding overlap
(2) Individual migration routes and spatial distribution of individuals and populations during migrationU.S. Fish and Wildlife ServiceU.S Geological SurveyMinnesota Cooperative Fish and Wildlife Research UnitNational Science FoundationVirginia Department of Game and Inland FisheriesGrace Jones Richardson TrustKramer, Gunnar R; Andersen, David E; Buehler, David A.; Wood, Petra B; Peterson, Sean M; Lehman, Justin A; Aldinger, Kyle R; Bulluck, Lesley P; Harding, Sergio; Jones, John A; Loegering, John P; Smalling, Curtis; Vallender, Rachel; Streby, Henry M.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
Raw Light-Level Geolocator Data from Golden-Winged Warblers Breeding at Three Sites in North America
No full textThe .lig files are comma separated time stamped ASCII data files where each time-stamped record is on a separate line. The header line of each file contains a three-variable string. Its meaning is unclear. The header lines are removed before data analysis. The .lig files can be opened by any text editors. The original data analysis is read into R using a package called "BAStag". The descriptions (e.g. CM05) next to the files represent the individual Golden-winged Warbler from which the data are collected.21 raw light-level data files (.lig) from geolocators (Biotrak, Wareham, UK; model ML6240, 2-min light-sampling regime) deployed on 20 individual Golden-winged Warblers from three breeding locations in North America. These data were collected to provide information on the migration routes and timing, and nonbreeding locations of individuals from these populations to inform conservation and management strategies. These data are being released following the publication of these findings.These data were collected during a project funded by the U.S. Fish and Wildlife Service and U.S. Geological Survey through Research Work Order No. 98 at the U.S. Geological Survey, Minnesota Cooperative Fish and Wildlife Research Unit; by the National Science Foundation through Postdoctoral Research Fellowship No. 1202729 (H. Streby); and by the U.S.D.A Natural Resources Conservation Service in a grant administered by J. Larkin.Kramer, Gunnar R; Streby, Henry M; Peterson, Sean M; Lehman, Justin A; Buehler, David A.; Wood, Petra B; McNeil, Darin J; Larkin, Jeffrey L; Andersen, David E. (2016).

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
