Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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
Evaluation of a language learning software
Full text linkGegenstand der Arbeit ist die Evaluation eines kommerziellen Sprachlern-Softwareprodukts zum selbstständigen Lernen von Französisch.Die Bewertungskategorien sind Usability, pädagogische Gestaltung, Spracherkennung und Akzeptanz.Dazu wurde eine zweiteilige empirische Studie durchgeführt. Sechs Testpersonen nahmen an einem Usability-Test teil, der auch Ausspracheübungen enthielt. Durch einen Pretest wurden die möglichen Testszenarien eingeschränkt.Zur Beurteilung der pädagogischen Gestaltung lernte eine Testperson einen Monat lang selbstständig mit dem Lernmaterial, wobei Lernprotokolle geführt wurden. Der Lernfortschritt wurde anhand eines Tests zu Beginn und am Ende der Lernphase ermittelt. Mit allen Testpersonen wurden Abschluss-Interviews durchgeführt.Die Resultate in den Kategorien Usability und pädagogische Gestaltung wurden anhand von Guidelines analysiert und dargestellt.Das evaluierte Produkt weist Mängel in Bezug auf Spracherkennung, Usability und pädagogische Gestaltung auf. Vor allem die Unzuverlässigkeit der Spracherkennung, die nicht-intuitive Benutzerschnittstelle, das mangelhafte Feedback und die Unübersichtlichkeit des Lernmaterials beeinträchtigen die Akzeptanz.Dennoch werden die Möglichkeiten, die das getestete Sprachlernprogramm für das Erlernen einer Sprache bietet, von den Testpersonen positiv bewertet.Die Ergebnisse der empirischen Studie bestätigen die Bedeutung von Guidelines und Usability-Tests für die Entwicklung von Sprachlernprogrammen.This master thesis describes the evaluation of a commercial language learning software product which is intended to be used for self-study of French. The assessment focused on usability, educational features, speech recognition and acceptance.An empirical study was carried out based on two approaches. A usability test was conducted with 6 subjects including also some pronunciation exercises. By means of a pretest the number of possible test scenarios was cut down.In order to investigate the educational features one subject used the product for one month and kept a diary. The learning progress was assessed by a test before and after. Interviews were conducted at the end with each participant.Guidelines were used to analyse and present the results referring to usability and educational features.The study revealed shortcomings of the product with respect to speech recognition, usability and educational features. The acceptance was in influenced by unreliable speech recognition, lack of intuitive user interface, insuffcient feedback and unclear structure of the instructional material. However, the participants appreciated the opportunities for language learning provided by the tested program.The results of the study confirm the importance of guidelines and usability tests for the development of language learning software
Integration of concepts of the problem-oriented medical record into the EHR
Full text linkElektronische Gesundheitsakten (EHRs von engl. "Electronic Health Record") dienen dazu, die Inhalte der medizinischen Dokumentation zu einem bestimmten Patienten zu sammeln. Die Idee der problemorientierten Dokumentation (POD) geht auf Lawrence L. Weed zurück, der die Dokumentation geordnet nach Problemen propagierte, um die Informationen jeweils in ihrem Kontext beurteilen zu können. Im Hinblick auf eine integrierte Gesundheitsversorgung müssen die Dokumentationsinhalte zwischen mehreren Institutionen ausgetauscht werden. Um eine breite Interoperabilität verschiedenartiger Informationssysteme zu erreichen, hat sich die Verwendung von Standards bewährt.In dieser Arbeit werden die speziellen Anforderungen einer shareable POD (einrichtungsübergreifenden problemorientierten Dokumentation) erhoben und existierende EHR-Standards darauf untersucht, inwiefern sie diese Anforderungen unterstützen. Die Standards EN 13940, ISO/EN 13606, HL7 CDA und IHE XDS wurden für die Untersuchung ausgewählt, da sie in nationalen EHR-Programmen zum Einsatz kommen können.Basierend auf einer Literaturrecherche wird ein shareable POD-Modell entwickelt, das jene Konzepte darstellt, die für eine shareable POD charakteristisch sind. Weiters wird ein Kriterienkatalog entwickelt, mittels dessen die Erfüllung der zentralen Anforderungen an ein shareable POD-Modell überprüft werden kann. Anhand der Spezikationen der Standards werden Vorschläge erarbeitet, wie eine shareable POD mit dem jeweiligen Standard umsetzbar ist. Diese Vorschläge werden dann auf Basis des erwähnten Kriterienkatalogs bewertet.Die Literaturrecherche zeigt, dass es keine allgemein anerkannte Spezikation für eine shareable POD gibt. Es wird aufgezeigt, dass die genannten vier Standards jeweils unterschiedliche Stärken und Schwächen hinsichtlich ihrer Nutzung zur verteilten problemorientierten medizinischen Dokumentation aufweisen. Die Ergebnisse bestätigen, dass die untersuchten Standards viele Anforderungen einer shareable POD erfüllen, aber nicht jeder von ihnen allen gerecht wird.Electronic Health Records (EHR) are used to store health information about a specific person. The formulation of problems and structuring all collected data in relation to these problems in order to keep the context of the information was proposed by Lawrence L. Weed as problem-oriented medical record (POMR).In integrated health care the EHR content needs to be shared between multiple health care providers. To facilitate interoperability of various information systems the usage of standards has become widely accepted.In this thesis the specific requirements of a shareable problem-oriented medical record are analyzed. Existing EHR standards are investigated to evaluate to which extent they fulfill these requirements. The standards EN 13940, ISO/EN 13606, HL7 CDA and IHE XDS were selected for this study since they can be used within national EHR programs.Based on a literature research a shareable POMR model is developed which represents the characteristic concepts. A set of criteria is defined to check the compliance of a standard with the model. The specifications of the standards are used to investigate feasible implementations of the model's structural elements. The identified proposals are reviewed if they are in line with the above mentioned set of criteria.The literature research reveals the absence of a generally accepted specification of a shareable POMR model. The results show that the considered standards have strengths as well as weaknesses regarding their application to a shareable POMR. Many requirements can be implemented on basis of the standards but not each standard meets all conditions
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
