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
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
Assessing the World Research Output on Electronic Information Resources (EIRs): A Scientometric Analysis
Full text linkThe present study depicts the growth of literature on electronic resources. In this regard, 2274 publications were collected from the Web of Science database from 1989 to 2018. The study attempts to measure year-wise and five-year block-wise distribution of publications using relative growth rate and doubling time, collaborative index, collaborative co-efficiency, and degree of collaboration. The highest number of publications, i.e., 472, was published in the 6th block 2014-2018. The sole author-produced 56.42% (1283) of the total publications, and double authors posted 19.48% (443). Authors from the USA have contributed the maximum number of publications compared to the other countries, and India stood 16th ranking in terms of productivity in this study period. The most prolific author authors Barker P, Korat O, and Tenopir C, contributed the highest 12 (0.53%) publications in e-resources literature, followed by Huang YM with 11 (0.48%) publications. Collaboration Index ranges from 1.53 (first block) to 2.72 (sixth block) with an average of 1.95 per joint authored paper, which implies the research team falls between 1 and 2 in the e-resources literature. Pennsylvania Commonwealth System of Higher Education PCSHE is a positively contributed institution with 40 publications, followed by the University of London (UK) with 33 publications
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
Horizontal thermal contractional strain of oceanic lithosphere: The ultimate limit to the rigid plate hypothesis
No full textDepth-averaged horizontal strain rates in oceanic lithosphere due to thermal contraction are determined. Calculated strain rates range from ≈10 -2 Myr-1 (near the mid-ocean ridge) to ≈10 -5 Myr-1 (for the oldest oceanic lithosphere). The average thermal contractional strain rate in oceanic lithosphere is ≈10 -4 Myr-1. Newly created lithosphere is displaced toward old ocean basins at a rate that is 1.35% of the half-rate of seafloor spreading, giving displacement rates of 0.1 to 1.1 km Myr-1. The bias in plate displacement rates estimated from marine magnetic anomalies, expressed as a percentage of the full spreading rate, is 0.60% or 0.85% depending on the age of the magnetic isochron used to estimate current plate velocity. The displacement rate due to thermal contraction parallel to a mid-ocean ridge could be as large as ≈10 mm/yr. Strain rates due to thermo-elastic stresses are an order of magnitude smaller than the strain rate calculated when these stresses are neglected
