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
From Subduction to Collision: Sedimentary Basin Constraints on Timescales and Geodynamic Drivers
No full textThesis (Ph.D.)--University of Washington, 2021The Tethyan orogenic belt extends from the western Mediterranean to southeast Asia and the exposed rocks and landscapes present today are records of multiple orogenic events. The most recent, the Alpine-Himalayan orogeny, evolved during the Mesozoic-Cenozoic closure of the Neotethys Ocean during the convergence of Gondwana with Laurasia. Over the last few decades, significant advances in geochemical and geochronological methods and their widespread application have created a high-resolution temporal framework that reveals that various proxy records of intercontinental collisions across the Alpine-Himalayan belt differ by tens of millions of years. Consequently, new questions have arisen, including how to unite these seemingly disparate records of subduction and collision into a temporally and spatially credible reconstruction.The work set forth in this dissertation situates the Anatolian segment of the Alpine-Himalayan orogenic belt in the broader discussion on the timescales and drivers of intercontinental collisions and their effect on biogeography. The various suture zones in Anatolia that delineate former branches of the Neotethys Ocean have complex and unresolved geodynamic reconstructions, including single and double subduction systems, pre-collisional subduction of lower plate terranes, forearc and backarc extension, ophiolite obduction, and protracted collisional deformation. Resolving these competing geodynamic scenarios is essential for paleogeographic reconstructions for refining the mechanistic links between subduction, accretion, and collision processes. Furthermore, the role of collisions in the early Cenozoic Anatolian archipelago in facilitating mammalian faunal exchange, including anthropoid primates, between Europe, Asia and Africa relies on accurate paleogeographic and topographic reconstructions.
Near-continuous deposition in western Anatolian sedimentary basins preserves an unbroken record of subduction through collision that is unparalleled across the Tethyan realm. This dissertation utilizes this sedimentary record by providing new stratigraphic, sedimentologic, petro- and geochronologic, and sedimentary provenance constraints on the chronology of collision along the İzmir-Ankara-Erzincan suture zone and the Intra-Pontide suture zone in western Anatolia. The sedimentary basin reconstructions presented in this dissertation, synthesized with existing datasets, provide a model for multi-stage continental collision that is applicable across the Tethyan realm.
Detrital zircon U-Pb geochronology and sandstone petrography data from the forearc-foreland Central Sakarya Basin in western Anatolia indicate that collision along the İzmir-Ankara-Erzincan suture zone began at 76 Ma, recorded as a major shift in provenance and the onset of exhumation, sediment recycling, and suture zone uplift. Furthermore, new stratigraphy, sedimentology and sedimentary provenance studies from the foreland Sarıcakaya Basin in western Anatolia reveal that significant upper plate deformation was delayed by 20 Myr. By 54 Ma, the Central Sakarya Basin was partitioned by a basement-involved thrust fault, and flexural loading from the thrust created the Sarıcakaya Basin. This 20 Myr protracted collision along the İzmir-Ankara-Erzincan suture zone can be explained by three Tethyan models for multi-stage collision: slab breakoff, relict basin closure, or subduction of thinned passive margin lithosphere.
The validity of relict basin closure is evaluated using detrital zircon U-Pb geochronology, detrital rutile U-Pb and trace element geochemistry, and sandstone petrography from sedimentary units across the Intra-Pontide suture. A major shift in provenance in the Paleocene-early Eocene caused by accretionary prism exhumation demonstrates that collisional stress from incipient İzmir-Ankara-Erzincan suturing could have been taken up by the Intra-Pontide suture. Furthermore, the sedimentary evolution of both suture zones reveals that the uplift and exhumation of the accretionary prism is an important signal of collisional geodynamics. Even though continental collisions assembled a larger landmass that favored trans-Tethyan mammalian dispersals, for 30 Myr after initial collision, collisional deformation did not form significant topography; marine barriers and endemism persisted until the late Eocene. Accretionary orogenies, like those in Anatolia, likely have an important control on biogeography. The findings presented in this dissertation bear on fundamental questions regarding the interconnectedness of Earth systems, including the effects of plate tectonics, the causes of topographic change, and the geologic drivers of biodiversity
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

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.
