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
Age related changes in functional field of view (FFOV): a comparison of young and older adults
No full textThis dataset contains 2 x text files of raw data; 2 x text files of data; 1 x excel spreadsheet (original) & 2 x CSV (preservation) files.<br><br><br>The data was collected to test whether differences in parallel processing efficiency explain age-related changes in the FFOV (functional field of view). The current work measured the workload capacity coefficient, C(t)OR, for targets appearing at various retinal eccentricities in young and older adults. Derived from analysis of response time distributions, C(t)OR gauges the efficiency with which observers process multiple items simultaneously relative to the rate at which they process items individually. Subjects performed a speeded target identification task, with targets appearing at varying retinal eccentricities and in the presence or absence of visual clutter.<br><br><br>Data description: Eight young adult participants(4 female, 4 male; mean age = 21.4 years, SD = 2.7; mean years of education = 14.8, SD = 2.6; mean corrected far acuity = 16/20, SD = 2.4; mean corrected near acuity = 20/20, SD = 0) and eight older adult participants (4 female, 4 male; mean age = 74.0 years, SD = 5.0; mean years of education = 13.6, SD = 1.9; mean corrected far acuity = 23.8/20, SD = 4.2; mean corrected near acuity = 23.8/20, SD = 7.0) performed a visual target identification task. Targets were coloured letters X or O that appeared at varying eccentricities (2.0°, 6.0°, or 10.0°) above or below a central fixation mark. Targets appeared either singly or redundantly (one each equal distances above and below fixation), and appeared either against an empty background or surrounded by grey clutter. Each participant contributed 5184 trials.<br><br><br>Dependent variables included response times (RTs) and error rates, along with measures of workload capacity, the efficiency of multiple-target processing. In addition to raw data (ASP_RawYoungData.txt,ASP_RawOlderData.txt), the files attached include,<br><br><br>• mean RT and error rate for each participant, calculated as a function of trial type (single-target vs. redundant-target), target eccentricity (near vs. middle vs. far), and display clutter (present vs. absent) (ASP_RT_ACC.txt);<br><br><br>• mean RT and error rate for each young adult participant, transformed to account for age-group differences in mean raw scores, calculated as a function of of trial type, target eccentricity, and display clutter (ASP_RT_ACC.txt);<br><br><br>• the raw workload capacity score, COR, for each participant, calculated as a function of time, target eccentricity, and display clutter(ASP_CtTimelines.xlsx);<br><br><br>• summary workload capacity scores, Cz, for each participant, calculated as a function of time, target eccentricity, and display clutter (ASP_Cz.txt)
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
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
