    The 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

    “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 link
    We 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 link
    We 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

    Adapting design process of dental abutments for using SLM additive technology

    Budući da je u okviru dentalne protetike iznimno važna točnost dimenzija komponenti koje se u njoj primjenjuju kako ne bi došlo do neželjenih posljedica po pacijenta još uvijek postoje brojne nepoznanice kako iste postići ukoliko se pri proizvodnji koristi SLM (eng. Selective Laser Melting) tehnologija te materijali poput titana i CoCr. Tako je svrha ovoga rada bolje razumjeti što doprinosi nastanku deformacija pri proizvodnji složenih dentalnih nadogradnji kako bi se smanjila količina naknadne obrade pri čemu se koristi navedena tehnologija i spomenuti materijali te kao rezultat toga istaknuti smjernice koje je potrebno pritom primijeniti. U tom smislu osmišljene su dvije skupine artefakata pri čemu su jedni uzorci relativno jednostavne geometrije, a drugi konstrukcije koje predstavljaju pojednostavljene stvarne složene nadogradnje all on 6. Kod uzoraka varirani su poprečni presjeci, a kod konstrukcija njihove ukrute. Jedna i druga skupina proizvedene su kako iz titana tako i iz CoCr pomoću SLM printera te su svi artefakti toplinski obrađeni popuštanjem, a samo nekoliko konstrukcija je podvrgnuto narednim proizvodnim operacijama. Za snimanje i mjerenje artefakata korišten je elektronički mikroskop, a nakon toga napravljena je jednostavnija analiza u Excelu. Kako eksperiment sadrži 14 različitih uzoraka i 20 različitih konstrukcija kao rezultat analize prikazani su samo neki uzorci i konstrukcije. Tako je ustanovljeno da pri konstruiranju složenih nadogradnji treba pronaći kompromis između krutosti i rashladne površine dotične konstrukcije. Osim toga nužno je ukrutiti krajeve složenih nadogradnji kako bi se smanjio utjecaj deformacija na količinu naknadne obrade. Također, u tom smislu potrebno je smanjiti funkcionalne mjere ne više od 2 % za slučaj dimenzijski stabilnijeg titana i 3 % za CoCr.Given the critical importance of dimensional accuracy in dental prosthetics, where deviations can lead to undesirable consequences for the patient, there remains a significant knowledge gap regarding how to achieve such precision when employing Selective Laser Melting (SLM) technology, particularly with materials such as titanium and cobalt-chromium alloys. The objective of this study is to gain a deeper understanding of the factors contributing to deformation during the manufacturing of complex dental restorations in order to minimize the extent of post-processing required when utilizing the aforementioned technology and materials, and as a result to establish design guidelines that can be applied in practice. To this end, two sets of artifacts were developed in which the first set consists of samples with relatively simple geometries, while the second includes structures representing simplified versions of real all on 6 dental restorations. In the case of the samples, variations in cross-sectional geometry were introduced, whereas in the more complex constructions, different reinforcement configurations were tested. Both groups were fabricated using an SLM printer from titanium and CoCr and all of the artifacts underwent thermal treatment via annealing, while only a subset of the complex constructions was subjected to additional post-processing operations. Imaging and dimensional measurements were conducted using an electron microscope, followed by a preliminary data analysis performed in Excel. The experiment comprised 14 distinct sample geometries and 20 different restoration constructions and due to the scope of the study, only a representative selection of these is presented in the results. The analysis indicates that, when designing complex restorations, it is crucial to find the balance between the rigidity and the heat dissipation surface area of the structure. Furthermore, reinforcing the ends of complex restorations is necessary to reduce deformation and thus minimize post-processing. It is also recommended to reduce functional dimensions by no more than 2% for dimensionally more stable titanium, and by up to 3% for CoCr

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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 text
    In 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.
