Usability als Erfolgsfaktor digitaler Medienplattformen
No full textEntwicklungsfirmen stehen vor der Herausforderung, ihre digitalen Medienplattformen erfolgreich zu vermarkten. Mit einer zunehmenden funktionalen Parität der Plattformen wird insbesondere Usability als Differenzierungsmerkmal relevant. Gebrauchstaugliche Plattformen haben nachweislich höhere Akzeptanzraten, steigern das Arbeitsengagement und reduzieren Stress. Eine durchdachte Usability-Strategie ist somit nicht nur ein Designziel, sondern auch ein wesentliches Marketinginstrument. Vermarktungsstrategien mit Fokus auf Usability können in primäre, sekundäre und tertiäre Ansätze unterteilt werden. Primäre Strategien zielen darauf ab, Usability direkt zu steigern und das Auftreten von Nutzungsproblemen zu vermeiden. Sekundäre Präventionsmaßnahmen konzentrieren sich darauf, entstandene Usability-Probleme möglichst gut zu reduzieren. Tertiäre Vermarktungsstrategien zielen schließlich darauf ab, Unzufriedenheit durch negative Usability zu reduzieren und Vertrauen wiederaufzubauen
Einfluss von Usability auf das Arbeitsengagement und die emotionale Erschöpfung von Mitarbeitenden. Eine experimentelle Längsschnittuntersuchung
No full textArbeitsbedingungen beeinflussen das Wohlbefinden von Beschäftigten fundamental. Während Belastungsfaktoren wie Überstunden gut erforscht sind, ist die Wirkung von schlecht gestalteter Software selten systematisch untersucht. Die vorliegende Studie betrachtet daher die Wirkung von Usability auf das Arbeitsengagement und die emotionale Erschöpfung bei Beschäftigten. Dabei wird angenommen, dass höhere Usability von betrieblicher Software zu einem gesteigerten Arbeitsengagement und reduzierter emotionaler Erschöpfung führt. Zur Untersuchung wurde eine experimentelle Längsschnittuntersuchung mit Kontrollgruppen-Design verwendet. Zu zwei Messzeitpunkten wurden Usability, emotionale Erschöpfung und Arbeitsengagement bei 327 Mitarbeitenden an diversen Standorten einer Unternehmensgruppe erhoben. Zwischen den Messungen wurden bei der Interventionsgruppe Usability-Verbesserungen am System vorgenommen und eine Schulung durchgeführt. Die Interventionsgruppe berichtete nach der Intervention über signifikant höheres Arbeitsengagement und reduzierte emotionale Erschöpfung. Bei der Kontrollgruppe zeigten sich diese Effekte nicht. Damit unterstützen die Befunde der vorliegenden Untersuchung die Hypothese, dass Usability Aspekte des Wohlbefindens beeinflusst. Des Weiteren leitet sich aus den Ergebnissen ab, dass im Bereich der Arbeitspsychologie vermehrt die Gebrauchstauglichkeit interaktiver Systeme in Betracht gezogen werden muss.Working conditions fundamentally affect employees’ well-being. While stress factors such as overtime are well-researched, the impact of poorly designed software is rarely systematically examined. This study, therefore, examines the effect of usability on work engagement and emotional exhaustion among employees. It hypothesizes that higher usability of workplace software leads to increased work engagement and reduced emotional exhaustion. An experimental longitudinal study with a control group design was used for the investigation. At two measurement points, usability, emotional exhaustion, and work engagement were assessed among 327 employees at various locations within a corporate group. Between the measurements, the intervention group received usability improvements to the system and training. The intervention group reported significantly higher work engagement and reduced emotional exhaustion after the intervention. These effects were not observed in the control group. The findings of this study support the hypothesis that usability influences aspects of well-being. Additionally, the results suggest that in the field of occupational psychology, the usability of interactive systems must be increasingly considered
Die Macht der Triangulation: Effektive Anwendung von Mixed Methods-Designs in der UX-Forschung
No full textIn dem Vortrag werden einige verfahrenstechnische Fragen im Zusammenhang mit Mixed-Methods Designs erörtert, welche die Erhebung, Analyse und Triangulation quantitativer und qualitativer Daten innerhalb einer Studie beinhalten. Zu diesen Fragen gehören die Entscheidung über die Priorität oder Gewichtung der quantitativen und qualitativen Datenerhebung und -analyse in der Studie, die Reihenfolge der Datenerhebung und -analyse sowie die Phase(n) im Forschungsprozess, in denen die quantitativen und qualitativen Daten miteinander verbunden und die Ergebnisse integriert werden. Der Vortrag gibt einen methodischen Überblick über Priorität, Durchführung und Vermischung in sequenziellen und parallelen Designs und bietet einige praktische Anleitungen für die Behandlung dieser Fragen in Bezug auf UX-Research. Außerdem werden die Schritte zur grafischen Darstellung der Verfahren in einer Mixed-Methods-Studie skizziert
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
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
