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
Investigation of a Coarse Silt Deposit by Varied Rate CPTU Testing
Get PDFWell-explored methods for the interpretation of CPTU and laboratory tests for clay and sand materials exist, assuming undrained and drained conditions, respectively. The determination of design parameters in silt is not straightforward due to amongst other factors the presence of an unknown degree of partial drainage during CPTU testing which complicates the interpretation and influences the results. The geotechnical community has for a long time now attempted to establish an international acknowledged interpretation framework for intermediate soils such as silts, that often neither behave undrained nor drained but experience partial drainage during standard rate CPTU tests. In addition, silts are normally not homogeneous but have a rather complicated micro-layering that lead to a scattered and complex structure. The average engineering properties cannot be predicted without extensive testing.
Even though recent research draws more attention to the behaviour of these soils both in the field and in the laboratory, there still exist an absence of a comprehensive and basic engineering database of silts. The focus needs to be on the influence of the recognized partial drainage on the interpreted design parameters and methods needs to be developed on how to account for this. The aim of the present PhD study is to broaden the knowledge of silt behaviour both in the laboratory and in the field and to contribute to the improvement of a more confident interpretation framework. In particular, recommendations are needed on how to consider the influence of partial drainage on the determination of design geotechnical parameters.
To study the drainage behaviour of silt, an extensive field and laboratory research program was performed at the NTNU. The work was undertaken at the established Halsen- Stjørdal test site which is located north of Trondheim and consists of a 10 m thick natural, low plastic silt deposit. Alongside carrying out several standard CPTU tests, various investigations were conducted with penetration rates varying between 0.5 mm/s and 200 mm/s to cover the whole spectrum of drainage conditions. In addition, more than 40 dissipation tests were analyzed, that provide further insight into the development of pore pressures and drainage conditions at the site. To study the material behaviour of the silt, soil samples from the silt layer were taken and analyzed in the laboratory facilities at NTNU.
The laboratory analysis of the soil samples emphasize the difficulties of handling the material in the laboratory and confirm the importance of improving the methods for sampling and quality assessment and hence the confidence in the geotechnical design parameters. Recommendations are made on how to select consolidation and strength parameters in silt. Nevertheless, sample disturbance is likely to occur and may influence the results.
Varied rate CPTU tests show a strong rate dependency of the measured response on the penetration rate, typically with decreasing cone resistance and increasing negative excess pore pressure for increasing penetration rates. For many silts, the drainage conditions yield partially drained conditions during standard penetration. For high rate CPTU tests, the well-known Nkt approach reveals the most promising results for the undrained shear strength. For slow rate CPTU tests, the drained strength parameters are obtained using the NTH method. If standard penetration rate CPTU results are used for the interpretation, the undrained shear strength is overestimated whereas the drained friction angle is underestimated. Consolidation analysis of the measured dissipation data confirms the rate dependency on the established soil parameters. Dissipation data and consolidation analysis confirm drained behaviour after slow penetration tests whereas the faster tests show partial consolidated behaviour. If ignored, the presence of partial consolidation influences the interpreted coefficient of consolidation and needs to be accounted for to prohibit an underestimation of this parameter. To prevent misinterpretation of geotechnical design parameters, it is necessary to carry out additional varied rate tests in deposits where partial drainage is likely to occur.
The results and findings from the present PhD study on a natural silt deposit highlight the challenges when dealing with silty materials and broaden the database internationally. In particular, the research emphasizes the importance of recognizing and accounting for partial drainage when interpreting CPTU tests in silts. It is hoped that this study may contribute to improved practice for how to establish realistic strength and consolidation parameters for silts enabling safe and economical designs
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

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.
