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
Entwicklung eines Herstellungsverfahrens für 3D-gedruckte patientenindividuelle Hilfsmittelkomponenten aus Flüssigsilikonen und thermoplastischen Kunststoffen
No full textThe orthopaedics sector is undergoing major transition, not least because of the increasing shortage of skilled workers as well as mounting cost pressure. Therefore, frequently still very manual manufacturing processes are to be automated and digitised. Apart from that, there is a need for optimization concerning patient specific shaping of assistive aid components. This is because conventional manufacturing techniques are limited, especially regarding the combination of a high performance load bearing material and a cushioning component. These hybrid products cannot reasonably be produced by either conventional methods or state of the art additive processes, currently.
For this reason, in the context of this work a holistic production process for additive manufacturing of patient specific assistive aid components from silicones and thermoplastics is being devised, to contribute to the solution of the aforementioned challenges in the orthopaedics sector.
To implement the overall process, amongst a fulfillment system for data transmission, a software solution for the automated creation of the connections of sub objects made from different materials is being developed. Additionally, a software solution for generating the machine code for the additive manufacturing of the product model is being worked out.
Based on this, two different 3D printing systems are being constructed that can produce the previously prepared product models as hybrid products from liquid silicone rubber and thermoplastics or in combination with high performance thermoplastics. To ensure the necessary quality of the additively manufactured assistive aid components for the care of the patient, a quality management system based on DIN EN ISO 13485 is being conceptualized.
Ultimately, the proposed holistic manufacturing process was successfully validated by the production of a soft socket from a liquid rubber silicone and a high performance thermoplastic. Therefore, the groundwork for the successful deployment of the process in the medical and orthopaedics sector has been laid.Die Orthopädiebranche befindet sich derzeit in einem starken Wandel, was nicht zuletzt auf den zunehmenden Fachkräftemangel sowie einen steigenden Kostendruck zurückgeführt werden kann. Demzufolge sollen die vielfach noch händisch geprägten Fertigungsprozesse sukzessive automatisiert und digitalisiert werden. Dessen ungeachtet besteht Optimierungsbedarf in Bezug auf eine patientenangepasste Gestaltung der individuellen Komponenten von Hilfsmitteln, da die konventionelle Fertigung insbesondere in Hinblick auf die Herstellung der Materialkombination eines belastungsfähigen Hochleistungsmaterials mit einer polsternden Komponente nach wie vor mit Einschränkungen verbunden ist. Diese Hybridprodukte können derzeit weder mithilfe von konventionellen Verfahren noch unter der Anwendung von bestehenden additiven Verfahren mit einem vertretbaren Aufwand hergestellt werden.
Aus diesem Grund wird im Rahmen dieser Arbeit ein ganzheitliches Herstellungsverfahren zur additiven Fertigung von patientenindividuellen Hilfsmittelkomponenten aus Silikonen und Thermoplasten entwickelt, um einen Beitrag zur Lösung der Herausforderungen in der Orthopädiebranche zu leisten.
Zur Umsetzung des Gesamtprozesses wird neben einem Auftragsabwicklungssystem für die Datenübermittlung auch eine Software zur automatisierten Generierung einer Verbindung der Teilobjekte unterschiedlichen Materials entwickelt. Zusätzlich wird eine Softwarelösung zur Erzeugung eines maschinenfähigen Codes für die additive Fertigung des Produktmodells erarbeitet. Auf dieser Basis werden zwei unterschiedliche 3D Drucksysteme entwickelt, mit denen die generierten Produktmodelle als Hybridprodukte aus Flüssigsilikonen und Thermoplasten oder kombiniert mit Hochleistungsthermoplasten hergestellt werden können. Nicht zuletzt wird ein Qualitätsmanagementsystem in Anlehnung an die DIN EN ISO 13485 ausgearbeitet, das die zur Patientenversorgung erforderliche Qualität der additiv gefertigten Hilfsmittelkomponenten sicherstellt.
Schlussendlich kann das entwickelte ganzheitliche Herstellungsverfahren am Beispiel der additiven Fertigung eines Weichwandinnentrichters aus einem Flüssigsilikon und einem Hochleistungsthermoplast validiert und damit die Grundlage für einen erfolgreichen Einsatz des Gesamtprozesses im Sanitäts und Orthopädiebereich geschaffen werden
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.
