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
Virtual Reality Training for Incident Commanders on Mobile Devices
Get PDFPraxisbezogenes Training ist für Führungskräfte der Feuerwehr elementar, um Einsatzszenarien in Hochstresssituationen abarbeiten zu können. Aufgrund finanzieller, personeller und organisatorischer Restriktionen kann diese Ausbildung oftmals nicht in dem Umfang durchgeführt werden, wie es notwendig wäre. Die vorliegende Arbeit zielt darauf ab, im Rahmen der Design-Based-Research eine prototypische VR-Simulationsumgebung für Feuerwehreinsätze zu entwickeln. Die Führungskräfte sollen hierdurch unabhängig von Zeit und Ort Einsatzszenarien individuell trainieren können. Das Ziel der Forschungsarbeit besteht darin, Anforderungen für diese Simulation zu sammeln und mit der Zielgruppe zu evaluieren. Zu Beginn diente eine Inhaltsanalyse, um aus verwandten Arbeiten und Design-Patterns für Serious-Games, Anforderungen abzuleiten. Ergänzt wurden diese durch Erkenntnisse aus einem Ablaufdiagramm für Gefahrguteinsätze und Ansätze des Autors. Im weiteren Schritt erfolgte die Evaluation von Anforderungen mit fünf Probanden durch ein teilstrukturiertes Interview in Verbindung mit einem Ablaufdiagramm und einem Papierprototyp. In der Folgeiteration wurde eine Evaluation mit fünf weiteren Teilnehmern als teilstrukturiertes Interview durchgeführt. Hierbei kamen ein Ablaufdiagramm sowie ein High-Fidelity-Prototyp auf einem Tablet in Verbindung mit dem Think-Aloud-Process zum Einsatz. Im Ergebnis konnten 318 Anforderungen gesammelt werden, von denen 100 in die Prototypen eingeflossen sind. Daneben wurde ein Ablaufdiagramm modelliert um Prozesse eines Gefahrguteinsatzes zu beschreiben. Sowohl für die Entwicklung des Prototyps wie auch als Dokument für die Lernenden hat sich diese Art der Darstellung bewährt.Realistic training possibilities for incident commanders in fire services are very important for improving the quality of their work in high-stress-environments. Because of financial, personnel and organizational restrictions, in many cases such training does not occur as frequently as it should. Incident commanders should have the option of individual training independent of time and location. The aim of this thesis is to create a virtual reality prototype to simulate incidents for fire service commanders using a design-based-research approach to simulate incidents for fire service commanders. Incident commanders should have the possibility for an individual training independent of time and location. The thesis collects requirement for the appli-cation and evaluates them with the target group. In the first step, a content analysis was used to analyze studies and Serious-Games Design-Patterns. Moreover a flow-chart for hazardous materials incidents and approaches from author were analyzed. In the first iteration the requirements were evaluated by five test persons with a semi-structured interview, a flow-chart and a paper prototype. The second iteration contains a semi-structured interview with five other test persons, a flow-chart and a high-fidelity prototype. The result is 318 requirements, 100 of which are used in two prototypes. In addition, a flow chart describes the processes of hazardous materials incidents. This flow chart was important in the prototype design process and is used as learning material for end users
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
