    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

    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

    Purpose This paper aims to present the newly founded Swedish Aeronautical Research Center (SARC), based on the triple helix theory, to foster the seamless Swedish aerospace research interplay between academia, research organizations and industry. Design/methodology/approach The paper is a technical paper, mainly relating and explaining sources and concepts for research planning and organization. Used concepts are the triple helix approach (for socioeconomic effects), the role of academia and industry interplay for education and the technology readiness level (TRL) concept for strategic research planning. Focusing on the establishment of a graduate school, lessons learned from previous national research schools are also presented. Findings The paper gives an overview of and explains the interplay between politics, social welfare and industrial Ramp;D needs, with the academic viewpoint of aeronautical research and education. Shortcomings in both the use of TRL for research program planning and the Swedish competence cluster system are identified and remedies suggested. The main findings are suggestions for future actions to be conducted by SARC in the fields of research and education. Originality/value So far, no publication about the newly founded SARC has been made yet. It is unique in the way that it makes substantial use of national technical documents so that this information becomes available for non-Swedish speakers. Additionally, the perhaps-unique system of industrial competence clusters is presented

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    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

    Aircraft Systems Conceptual Design : An object-oriented approach from <element> to <aircraft>

    No full text
    Aircraft Conceptual Design (ACD) is facing new challenges on the way to enhanced fidelity level required of the nowadays complex system design. Namely the integration of models and simulations of different fidelity levels to enhance the analysis capability while maintaining a streamlined, transparent, and low cost working process is required. In this thesis, the use of object-oriented Knowledge-Based Engineering (KBE) methods to enable an early integration of simulation models within the ACD phase are presented. Careful investigations of modelling and simulation approaches of multi-domain systems are carried out before, and their use in the ACD phase is examined regarding the efficiency between spend effort and result in accuracy. Enabling the named topics, a central, parametric information model approach is presented. By the extended use of XML, XSD and XSLT, domain-specific models can be translated from this dataset, supporting a direct CAD and automated simulations integration. Modelling systems as graph networks is a simple approach for unified modelling within the conceptual design stage. Based on this theory, the similarity of different modelling approaches like Dependency Structure Matrix (DSM), MDDSM, or Channel-Agency Networks is shown. Using object-oriented programming, all these and more aspects such as e.g. Fault Tree Analysis (FTA) can be globally handled as one graph set. Based on the outcomes of the theoretical part, the development of a ACD framework is described. Backed by a central XML-based namespace, this framework integrates a complete CAD environment to ensure an appropriate environment for the geometric domain modelling. Furthermore, the use of KBE for automated simulation model integration is exemplified by a whole aircraft simulation including the hydraulic aircraft flight control system (FCS).Mit steigenden Anforderungen durch immer mehr optimierte, leistungsfähigere, zuverlässigere und langlebigere technische Produkte nimmt die Modellierung und Simulation einen immer größeren Stellenwert ein. Um das Zusammenspiel von Systemen bereits im Flugzeugvorentwurf analysieren zu können, bedarf es einer geschickten Systemmodellierung und geeigneter Arbeitsprozesse, die die Erstellung von Simulationsmodellen auf Basis unvollständiger Daten- und Informationslage ermöglichen. Vor Allem, um das volle Optimierungspotential moderner, integrierter elektrischer Systemarchitekturen ausschöpfen zu können, ist eine Einbeziehung dieser in das Gesamtkonzept innerhalb des Flugzeugvorentwurfs notwendig. In dieser Arbeit wird ein wissensbasierter Arbeitsprozess (englisch: Knowledge-Based Engineering) für den Flugzeugvorentwurf präsentiert, welcher die Zusammenführung unterschiedlicher Informationen – wie z.B. Domänen- und Produktspezifischer Daten ermöglicht. Dies soll die Einbeziehung der Bordsystemarchitekturen dienen, um die gestiegenen Genauigkeitsanforderungen im Flugzeugvorentwurf bewältigen zu können. Dem vorausgehend werden verschiedene Modellierungsgrundsätze erörtert und ihre Anwendungsmöglichkeit im Hinblick auf die mögliche Implementierung und Anwenderfreundlichkeit im Flugzeugvorentwurf diskutiert. Ausgehend von den theoretischen Überlegungen wird die Entwicklung eines XML-basierten Flugzeugvorentwurfsprogramms beschrieben, das die vollständige Integration eines kommerziellen CAD-Werkzeuges ermöglicht. DesWeiteren werden die Möglichkeiten aufgezeigt, welche sich durch den Einsatz eines universalen Modells im XML-Format ergeben. Durch Interpretation der Produktdaten in Form eines Graphennetzwerks werden verschiedene Modellierungs- und Analysemöglichkeiten wie Beispielsweise DSM und C-A Net Modell erörtert und die Integration von Teilaspekten wie der Systemzuverlässigkeit aufgezeigt. Ziel ist ein universeller Modellierungsansatz, der eine plausible, verständliche und anwenderfreundliche Integration der verschiedenen Teilaspekte des Flugzeugvorentwurfs ermöglicht sowie die Einbindung domäne-spezifischer Programme (wie z.B. CAD) mit Hilfe einer parametrischen, auf XML basierenden Datenbank erlaubt

    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
