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
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
NUMERICAL STUDY ON CYCLIC SEISMIC RESPONSES OF UNREINFORCED MASONRY WALLS RETROFITTED WITH LOW-STRENGTH ENGINEERED CEMENTITIOUS COMPOSITES
No full textMost of the faults of Tien Shan Mountain are situated in Central Asia. Even the small faults of the mountain may cause risk to the nearby cities, such as Almaty, Kazakhstan, with a population of about 1.8 million people. Over half of the buildings in Almaty are unreinforced masonry buildings, followed by reinforced masonry, confined masonry, and reinforced concrete, and a minority of structures are from wood and steel. Unreinforced masonry buildings may demonstrate brittle behavior under seismic activities. Earthquakes such as those happened in the past of Almaty can damage most of the city and its inhabitants. The catastrophic destruction action of the earthquake can be mitigated by the construction of high strength, and ductile buildings, which can withstand large deformations with minor damages. Thus, to improve the response of existing unreinforced masonry structure, different studies propose the use a retrofitting, which can increase the deformation capacity and ductility of the unreinforced masonry walls. This thesis focuses on parametric study on cyclic responses of unreinforced masonry walls retrofitted with low-strength Engineered Cementitious Composite (ECC). The new retrofitting material, Engineered Cementitious Composite (ECC) with a high tensile strain hardening rate, was retrofitted to the unreinforced masonry wall in this study. Previous experimental studies have shown that the normal strength ECC can increase the strength of URM but has little effect on the deformation capacity due to the incompatibility of the masonry and composite. Moreover, a numerical study by Sailauova (2022) has shown that the low-strength ECC can increase the deformation capacity under monotonic loading because of stiffness compatibility between the masonry wall and composite. Considering the prior studies, this study addresses to the cyclic response of the masonry wall since the earthquake has a cyclic nature. The application of low-strength ECC approved the hypothesis that it can reach more deformation rather than normal-strength ECC, since it matches the stiffness of the masonry wall resulting in more ductile behavior.
This study aims to investigate the cyclic response of unreinforced masonry walls subjected to cyclic seismic loadings. This thesis presents a numerical study on in-plane cyclic behaviors of the unreinforced masonry wall retrofitted with the low-strength ECC. The numerical study was conducted on nonlinear two-dimensional models in ABAQUS software using a simplified micro-modeling approach for the masonry wall and the concrete damage plasticity for the ECC. The dynamic analysis using explicit analysis technique was adopted due to the non-linear behaviors of the masonry wall and ECC. The model was verified from an existing experimental study. The study parameters include the strength of ECC, wall aspect ratios, and vertical pressures, which represent typical wall geometry and gravity loading conditions of unreinforced masonry buildings in Almaty. This study concentrates on 0.5, 0.75, and 1.0 wall aspect ratios and walls subjected to 0.43, 0.60, and 0.78 MPa vertical pressures, or in axial force ratio 0.10, 0.15 and 0.19, respectively. Moreover, the proposed material, Engineered Cementitious Composite (ECC), with different compressive strengths (10, 20, 30, 40, and 50 MPa) was evaluated. The behavior of the retrofitted wall under the cyclic loading was compared to that under the pushover analysis.
The numerical study results concluded that with the increase of ECC compressive strength on the retrofitted masonry wall, deformation capacity and ductility decrease, while wall strength and stiffness increases simultaneously. However, as the ECC becomes stronger, energy dissipation decreases. The effect of ECC for different wall aspect ratios on wall strength decreases with the increasing aspect ratio, but increases with the increase of vertical pressure. This is because the friction between the brick units and mortar increases. Regardless of the aspect ratio and vertical pressure, low strength ECC with compressive strength 10 and 20 MPa improve the lateral deformation capacity of the masonry wall. Moreover, the pushover analysis shows a slower strength reduction than the cyclic loading analysis due to the cumulative damage from the cyclic loading

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.
