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
On Design Load Prediction and Extreme Response Modelling of Floating Offshore Renewable Energy Structures
Get PDFFLOATING offshore renewable energy (FORE) is a marginal industry and as such cost reductions are essential in order for it to become competitive with other forms of electricity generation. Design practices for evaluating the extreme responses of FORE devices are still under consideration by standards authorities, thus methods that enable potential speeding up of the design and development phases, particularly physical model testing are needed. Probabilistic design approaches have proved effective in bringing down costs in the aerospace and automobile industries and so provide a potential route to viability by allowing partial safety factors to be reduced. However, the scarcity of real world data and early development stage of the sector mean that the suitably large data sets needed to evaluate extreme responses and uncertainties have to be generated numerically. This poses a challenge when there is a trade-off between fidelity and run time. This thesis seeks to understand the extent to which fast mid-fidelity models such as WEC-Sim (a potential flow, Cummins equation based model) can model the extreme responses of FORE devices compared with physical experiments and where and how short design waves can be used in speeding up the prediction of design loads. A WEC-Sim numerical model was found to perform reasonably accurately in evaluating extreme mooring responses of a generic point absorber wave energy convertor (WEC), with a median error relative to physical experiments of around 10%. It was then used to develop a methodology for using short design waves during physical model tests, conducted in the COAST lab at the University of Plymouth, and evaluated for a hinged raft type WEC and semi-sub floating offshore wind turbine (FOWT). The approach used constrained focused waves scaled to an inflated target percentile amplitude or response in place of the one to three hour irregular wave time series commonly used in the prediction of design loads. Recommendations were given on the suitability of the method in different sea conditions; for different response types; and on how to calibrate the waves in physical experiments. Constrained NewWave (CNW) and conditional random response wave (CRRW) profiles were compared and found to perform well in different situations, with the CNWs being a better choice when modeling snatch loads in steep sea states for a hinged raft type WEC. It was found that a single, frequency specific phase correction calculated from a focused wave could be used to calibrate the constrained focused waves, greatly speeding up the calibration time. Difficulties in the calibration of the short design waves in steeper sea states make the developed method increasingly difficult to apply close to the wave breaking limit. Physical experiments on a semi-sub FOWT were conducted and the results compared with a WEC-Sim model for the responses of pitch, nacelle acceleration and mooring load. It was found that an additional drag term had to be added to the numerical model to improve the accuracy of the low frequency surge motions and mooring loads. Furthermore, it was found that the wave theory used to generate the wave surface elevation input to the edited numerical model had a significant impact on the surge response, resulting in a difference of over 30%. A constrained wave group was proposed as an alternative short design wave when studying the moorings of Semi-subs. This thesis has developed a short design wave method to improve the efficiency of the design process of FORE devices, provides several case studies on the methods applicability and has assessed the extend to which mid-fidelity numerical models are able to model extremes
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

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.
