Alternative digital platforms: comparative analysis through the lens of Corporate Aikido
No full textAbstract
Competing with dominant players in the digital platform (DP) economy is an increasingly complex and expensive endeavor for alternative digital platform (ADP) providers trying to disrupt established platform ecosystems. Nevertheless, ADPs position themselves deliberately in the competitive space of large competitors, targeting customer groups whose values and mindsets differ from mainstream DPs. Although there are many examples to find in practice, the variety of ADPs across different DP ecosystems and industries, especially in regards of strategic objectives, directions and characteristics, has not been researched in-depth yet. Based on a systematic, practice-based artifact review, this paper analyses and compares 105 ADPs in the competitive space of dominant DP ecosystem players. The study utilizes the theory of Corporate Aikido as an analytical framework, mapping the strategic elements of overthrowing established value propositions and turning a competitors’ strengths into weaknesses. Our findings indicate that privacy- and security-awareness, empowerment and inclusivity, premium quality and curation, open source and free access, uncensored, transparent and decentralized platforms as well as ecological and climate-friendly offers shape the landscape of alternative approaches in today’s DP economy. The results are subsequently discussed, yielding managerial implications and future opportunities for DP research
Integrated IT cost tables as a tool for software architecture and IT production decision and to determine the manufacturing costs of software as a service applications
No full textDiese Dissertation demonstriert die Möglichkeit, kundenspezifische integrierte IT-Kostenkalkulationen für die effiziente Bereitstellung von SaaS-Anwendungen zu verwenden. Die getrennten Kostensichten aus IT-Entwicklung und IT-Produktion werden integriert und mit Kosteninformationen verschiedener IaaS-Anbieter erweitert. Darüber hinaus ist es mit der skizzierten Methode möglich, unterschiedliche Produktionsarchitekturen, Betriebs- und Endkundenbetreuungsmodelle zu berücksichtigen. Das Verfahren ermöglicht somit eine transparente Integration der oben genannten Kostensichten zur Entscheidungsunterstützung für die verschiedenen Umsetzungsmöglichkeiten von SaaS-Angeboten, indem es die zu erwartenden Gesamtkosten und kostenseitige Effizienzoptimierungen bei der Kombinationsauswahl ermittelt. An einem zentralen Beispiel werden die kostenbedingten Unterschiede durch die unterschiedlichen Kombinationen möglicher Merkmalsausprägungen aufgezeigt. Die Anforderungen an das Verfahren wurden durch die Durchführung und Auswertung einer Umfrage unter SaaS-Anbietern abgeleitet. Im letzten Teil der Arbeit wurde versucht, das Verfahren mittels moderner Webtechnologien prototypisch abzubilden, um dessen technische Umsetzbarkeit zu demonstrieren. Die technische Realisierbarkeit in der Praxis soll durch die Erstellung eines Prototypen demonstriert werden. Der resultierende Prototyp stellt die Ergebnisse des Verfahrens tabellarisch sowie grafisch in Gesamt- und Einzelkosten dar. Ergebnis der Arbeit ist ein Berechnungsverfahren zur Ermittlung der Bereitstellungskosten von SaaS-Anwendungen. Mit dieser Methode kann im Vorfeld der Bereitstellung solcher Angebote der Einfluss verschiedener technischer und organisatorischer Merkmale auf die Bereitstellungskosten mit Hilfe einer Vorausrechnung ermittelt werden. Die Methode bietet damit Entscheidungshilfen für die verschiedenen Ausprägungsformen von SaaS-Anwendungen und schafft die Möglichkeit einer effizienten IT-Dienstleistungserbringung im SaaS-Kontext und kann einen Wertbeitrag zum Informationsmanagement leisten.This dissertation demonstrates the possibility of using customized integrated IT cost spreadsheets for the efficient delivery of SaaS applications. The separate cost views from IT development and IT production are integrated and expanded with cost information from different IaaS providers. Furthermore, with the method outlined, it is possible to consider different production architectures, operational and end customer support models. The method thus enables a transparent integration of the above-mentioned cost views to support decision-making for the various implementation options of SaaS offers by determining the expected production costs and cost-side efficiency optimizations in the combination selection. Using a central example, the cost-related differences through the different combinations of possible characteristic forms are shown. The requirements for the procedure were derived by conducting and evaluating a survey among SaaS providers. In the last part of the work, an attempt was made to depict the process as a prototype using modern web technologies in order to demonstrate its technical feasibility. The technical feasibility in practice should be demonstrated by creating a prototype. The resulting prototype presents the results of the procedure in tabular form as well as graphically in total and individual costs. The result of the work is a calculation method for determining the provision costs of SaaS applications. This method can be used in advance of the provision of such offers to determine the influence of various technical and organizational characteristics on these provision costs with the help of a forward calculation. The method thus offers decision support for the various characteristic forms of SaaS applications and creates the possibility of efficient IT service provision in the SaaS context and can make a value contribution to information management
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
A Taxonomy of Microlearning Applications for Organizational Learning
Full text linkTechnological development continues to advance, with the occurrence of new technologies requiring the acquisition of new expertise and skills to ensure effective adoption. In this context, digitally enhanced, needs-based, and contemporary learning concepts such as microlearning are becoming increasingly important. This trend extends to organizational settings, where newer generations of employees prefer modern training formats over traditional ones. While previous research has acknowledged the advantages of microlearning, it rarely addresses its implementation in enterprises and often lacks consistent terminology. Hence, this research captures the current landscape of organizational microlearning applications and provides structure through taxonomy development, informed by an analysis of conceptual and empirical sources. The taxonomy is organized based on 3 meta-dimensions – “content”, “setting”, and “digital representation” – comprising 12 dimensions and 66 characteristics. It enables a better understanding, comparison and further analysis of organizational microlearning applications in both academic and professional contexts
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
