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
Model-based optimization of the operation procedure of emulsification
No full textEmulsions are widely encountered in the food and cosmetic industry. The first food we consume is an emulsion, namely breast milk. Other common emulsions are mayonnaise, dressings, skin creams and lotions. Equipment often used for the production of oil-in-water emulsions in the food industry consists of a stirred vessel in combination with a colloid mill and a circulation pipe. Within this set-up there are two main variations: i) Configuration I where the colloid mill acts like a shearing device and at the same time as a pump. This configuration is used in the majority of the production facilities, and ii) Configuration II where the shearing and pumping action are not coupled. The operation procedure for obtaining a certain predefined emulsion quality is often established based on experience (best practice). This is most probably time-consuming (e.g. large experimental efforts for new developed products) and it is also unclear if the process is operated at its optimum (e.g. in minimum time). An other drawback is that there is no feedback during the production process. Hence, it is not possible to deal with disturbances acting on the process. A possible consequence is that, at the end of the production process, the product quality specifications are not met and the product has to be classified as off-spec. In order to be able to enlarge the efficiency of the production processes and to shorten the time to market of new products - and therewith create an advantage over competition - it is necessary to overcome these limitations of the current operation procedure. In the work reported a first step is set into this direction. A model describing the droplet size distribution (DSD) and the emulsion viscosity as function of the time was developed and several off-line optimization studies were performed. The model comprises several fit parameters and experiments were performed in order to estimate the values of these parameters. A number of additional experiments were performed to compare the simulated results with the measurements (model validation). The results of the parameter estimation and the model validation show that the simulated results are qualitatively in good agreement with the measurement data. Given the overall performance of the model it is expected that the model quality is sufficient to render practical relevant optimization results. Although the optimization studies have been performed for a model emulsion, small scale equipment and are not yet experimentally validated, the results of this work strongly suggest that it is indeed possible to minimize the production times and to shorten the product development times for new products. This overall conclusion is based on the following observations: 1) The optimization results show that it is beneficial to produce emulsions with Configuration II: - Configuration II allows the production of emulsions with a bi-modal DSD. No operation procedure was found for the production of such an emulsion in Configuration I. - The production of emulsions in Configuration II is always at least as fast as in Configuration I. 2) The followed approach allows to calculate: * If an emulsion with a certain, predefined, DSD and emulsion viscosity can be produced. * How the process should be controlled in order to produce such an emulsion. * How the process should be controlled to produce this emulsion in minimal time. 3) The optimization results show that it is possible to produce emulsions with: * A bi-modal DSD. * Less oil while maintaining a similar DSD and value of the emulsion viscosity evaluated at a shear rate of 10 1/s by adapting only the operation procedure. Hence, the addition of extra stabilizers is not considered. This offers possibilities for the production of a broader range of emulsion products and could direct product development in a new direction. Based on this, it is worthwhile and therefore recommended to expand this research work in the direction of industrial emulsions.Design, Engineering and Productio

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.
