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
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
Antarctic continental shelf benthos under changing marine icescapes – structure, function and behaviour
Get PDFAs climate change and global warming advance, the coastal seas of Antarctica, although isolated oceanographically by the Antarctic Circumpolar Current, are undergoing physico-chemical transformations, including alterations to the marine cryosphere (icescape). These environmental modifications will have implications for Antarctica’s varied and connected marine ecosystems, component biological communities, and associated ecosystem services, over diverse spatial and temporal scales.
Transitions of Antarctic marine icescapes from “white to blue” are being evidenced by, for example, sea-ice decline and glacier retreat over Antarctica’s vast continental shelf, one-third (1.6 million km2) of which is covered by floating extensions of the Antarctic Ice Sheet: “ice shelves”. In high/polar-latitude marine environments, loss of ice cover can create new or greater exposure to open-water conditions with opportunities for primary production and associated organic matter export (food-fall) to the benthos (communities of seafloor-dwelling organisms), which includes the majority of Antarctica’s known species (biodiversity).
Constituting a critical component of the Southern Ocean ecosystem (and food web), Antarctic seabed biodiversity has evolved in partial isolation and relative constancy of physical conditions, punctuated by glaciations, and exhibits considerable endemicity in particular taxonomic groups and specific adaptations and traits. Furthermore, the benthos of Antarctica’s continental shelf is becoming increasingly recognised for its role in storing carbon (as part of blue carbon), a function (and an ecosystem service) potentially supporting climate change mitigation. How such specialised biota, the communities they make up, and the services they provide will be impacted by climate- and global-warming-induced environmental changes, including marine icescape transitions, is yet to be fully realised, hindered, in part, by knowledge gaps of benthic assemblages at the margins of and beneath ice shelves, where comparatively little ecological sampling has been conducted to date and where physical environmental change may be most profoundly/conspicuously exhibited.
This DPhil thesis aims to investigate, and enhance understanding of, the structuring, function and behaviour (three interconnected components) of contemporary Antarctic continental shelf benthic assemblages under different regimes of ice cover (e.g., sea-ice and ice-shelf environments) and in seldomly-accessed areas increasingly vulnerable to climate change, including ocean and atmospheric warming. The research encompasses varied datasets and methodologies (including the leveraging of a functional group approach), and sampling across contrasting continental shelf areas spanning the breadth of a high Antarctic to southern high-temperate region, and (i) determines megabenthic assemblage configurations adjacent to an evolving ice-shelf margin (within an intermittent rarely-accessible coastal polynya), and potential environmental drivers; (ii) discerns the variability in zoobenthic carbon storage, a function of the zoobenthos, across a southern polar gradient, and potential influences; and (iii) newly discovers macrobenthic assemblages competing for space deep beneath an ice shelf, establishes the nature of such competition, and compares findings to those of open-water environments (across latitudes).
Overall, the research contributes to increasing knowledge- and evidence-bases around Antarctic seabed life and its complexities, including of areas potentially facing significant environmental modifications, and provides new bio/ecological baselines (pertaining to structure, function and behaviour of benthic assemblages) from which change can be evaluated. The thesis outputs can support present and (near-)future marine ecosystem-based management, conservation measures, and spatial planning within national and international frameworks, including in view of evolving and emerging polar marine environments in a warming world

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.
