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
An Expanding Meso-Carnivore: Fisher (Pekania pennanti) Occupancy and Coexistence with Native Mustelids in Southeast Alaska
No full textAround the world, species’ distributions are shifting in response to climate change, with many species exhibiting range expansion toward the poles. These range expansions often create new species interactions that are not well understood. The fisher (Pekania pennanti) is a mammalian carnivore that has recently expanded its range into the coastal temperate rainforest of Southeast Alaska (SEAK). Little is known about its occupancy and effects on native species in SEAK. The goal of this project was to examine fisher occupancy, density, and co-occurrence with American marten (Martes americana) and ermine (Mustela erminea) in SEAK. Twenty-five paired camera and hair snag stations (50 unique sites) were deployed north of Juneau, Alaska from January−April 2018, resulting in detection of 15 species and collection of 204 hair samples. Polymerase chain reactions conducted on DNA extracted from hair samples showed that 16 of those hair samples were from fisher. From the fisher DNA samples, only one individual fisher was identifiable (a female), making a fisher density analysis unfeasible. However, camera trap data allowed us to conduct single species occupancy analyses at both local and broad scales, which showed that fisher detection was negatively impacted by snow density, but positively affected by whether a fisher had been detected at the previous occasion (average site scale p = 0.24 (95% CI = 0.12, 0.40); average grid scale p = 0.15 (95% CI = 0.07, 0.30)). Fisher occupancy was positively impacted by snow density at the local scale and positively associated with vegetation height at a broader scale (average site scale psi = 0.30 (95% CI = 0.08, 0.72); average grid scale psi = 0.40 (95% CI = 0.003, 0.83)). Although high snow density has the potential to decrease the impact of a fisher’s high foot-load by making it easier to travel on top of the snow, the effect may not be powerful enough to overcome the high energetic costs associated with movement in deep snow and therefore not positively contribute to detectability on a day-to-day basis. The slight positive correlation between snow depth and snow density in our analysis may corroborate this (r = 0.43). Among mustelid species, top models from two-species occupancy analyses indicated that fisher have no effect on marten or ermine occupancy, although there was slight support for the model indicating that fisher may negatively impact marten occupancy. Analysis of diel activity patterns and temporal overlap indicated that marten and ermine adjust their activity patterns in the presence of fisher, potentially to reduce overlap. Furthermore, ermine displayed temporal avoidance of marten, whereas marten activity was unaffected by ermine presence. A small fisher sample size made it unfeasible to examine shifts in fisher activity patterns in the presence of marten and ermine. These results show that mustelids in SEAK currently co-exist through temporal partitioning, with smaller-bodied mustelids avoiding larger, more dominant mustelids. However, if the fisher population continues to expand, these species interactions may shift and increase the potential for competition between fisher, marten, and ermine in SEAK. Overall, this research indicates that fisher, including a female, currently occupy the study area and prefer areas with taller trees and higher snow density, indicating that other areas of Southeast Alaska may be suitable fisher habitat. This study’s methodology was unable to measure fisher density, but was able to identify important predictive covariates associated with fisher occupancy in SEAK, and illustrate temporal partitioning patterns among mustelid species in the area. Future research to increase sample size and detect species’ trends in SEAK over time will be beneficial, but this pilot research was an important first step in developing a monitoring protocol and management plan for fisher in SEAK.masters, M.S., Natural Resources -- University of Idaho - College of Graduate Studies, 2019-0
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
