    Development of the Industrial IoT Competences in the Areas of Organization, Process, and Interaction Based on the Learning Factory Concept
    (2017) Gronau, Norbert; Ullrich, André; Teichmann, Malte
    Lately, first implementation approaches of Internet of Things (IoT) technologies penetrate industrial value-adding processes. Within this, the competence requirements for employees are changing. Employees‘ organization, process, and interaction competences are of crucial importance in this new IoT environment, however, in students and vocational training not sufficiently considered yet. On the other hand, conventional learning factories evolve and transform to digital learning factories. Nevertheless, the integration of IoT technology and its usage for training in digital learning factories has been largely neglected thus far. Existing learning factories do not explicitly and properly consider IoT technology, which leads to deficiencies regarding an appropriate development of employees‘ Industrial IoT competences. The goal of this contribution is to point out a didactic concept that enables development and training of these new demanded competences by using an IoT laboratory. For this purpose, a design science approach is applied. The result of this contribution is a didactic concept for the development of Industrial IoT competences in an IoT laboratory.

    Four Parameters for Measuring Democratic Deliberation: Theoretical and Methodological Challenges and How to Respond
    (2018) Fleuß, Dannica; Helbig, Karoline; Schaal, Gary S.
    Although measuring democratic deliberation is necessary for a valid measurement of the performance of democracies, it poses serious theoretical and methodological challenges. The most serious problem in the context of research on democratic performance is the need for a theoretical and methodological approach for “upscaling” the measurement of deliberation from the micro and meso level to the macro level. The systemic approach offers a useful framework for this purpose. Building on this framework, this article offers a modular approach consisting of four parameters for conceptualization, measurement, and aggregation which can be adjusted to make the measurement of democratic deliberation compatible with the various general measurement approaches adopted by different scholars.

    Exploring Students’ Engagement Patterns in SPOC Forums and their Association with Course Performance
    (2018) Liu, Zhi; Pinkwart, Niels; Liu, Hai; Liu, Sannyuya; Zhang, Guangtao
    With the popularity of Small Private Online Courses (SPOCs) in higher education, a plentiful of discussion data has been increasingly generated in SPOC forums. With 752 undergraduates’ discussion posts, this study aims to investigate students’ engagement patterns within SPOC forums in terms of engagement behaviors and emotions. Firstly, we designed a behavioral code rule to identify posting- and content-level behaviors, and examined their association with course performance. Secondly, we built an emotion lexicon including positivity, negativity and confusion word sets, and adopted an emotion calculation approach to visualize emotional evolutionary trends and to examine emotional differences in registration types and course performance. The results show that, (1) the high-performing group was more active in the most engagement behaviors except for interactive postings. (2) The registered group delivered more threads and wrote richer vocabulary in post content. (3) Whether students were registered for a course or not did not have a significant effect on their emotional expressions, but the registered group exhibited more confusion in forum interactions at the end of the semester. (4) Positive emotion was prevailing for the entire population. Furthermore, compared with the low-achieving group, the high- performing group had higher emotion densities in three types of emotions.

    “Digital citizenship” revisited: the impact of ICTs on citizens’ political communication beyond the Western state
    (2018) Emmer, Martin; Kunst, Marlene
    The role of ICTs in political participation has been a core topic in political communication research for about two decades. Numerous studies have tested whether the enthusiasm about the mobilizing impact of ICTs holds true. Most have been conducted in Western countries and, therefore, reflect a Western-centric understanding of politics and participation. Although these studies have provided insight into the potential of ICTs for established democracies, political and cultural contexts from developing world regions such as sub-Saharan Africa (SSA) have thus far been neglected. However, given the rapid dissemination of ICTs (e.g., mobile phones) and their innovative application in everyday life in developing countries, regions like SSA should be of particular interest for research in this field. This article aims to highlight the shortcomings of Western research and to recommend adjustments in future efforts to investigate effects of ICTs, including developing world regions, in order to develop a more robust empirical grounding for theories of participation.

    Intentional Forgetting in Organizations: The Importance of Eliminating Retrieval Cues for Implementing New Routines
    (2018) Kluge, Annette; Gronau, Norbert
    To cope with the already large, and ever increasing, amount of information stored in organizational memory, “forgetting,” as an important human memory process, might be transferred to the organizational context. Especially in intentionally planned change processes (e.g., change management), forgetting is an important precondition to impede the recall of obsolete routines and adapt to new strategic objectives accompanied by new organizational routines. We first comprehensively review the literature on the need for organizational forgetting and particularly on accidental vs. intentional forgetting. We discuss the current state of the art of theory and empirical evidence on forgetting from cognitive psychology in order to infer mechanisms applicable to the organizational context. In this respect, we emphasize retrieval theories and the relevance of retrieval cues important for forgetting. Subsequently, we transfer the empirical evidence that the elimination of retrieval cues leads to faster forgetting to the forgetting of organizational routines, as routines are part of organizational memory. We then propose a classification of cues (context, sensory, business process-related cues) that are relevant in the forgetting of routines, and discuss a meta-cue called the “situational strength” cue, which is relevant if cues of an old and a new routine are present simultaneously. Based on the classification as business process-related cues (information, team, task, object cues), we propose mechanisms to accelerate forgetting by eliminating specific cues based on the empirical and theoretical state of the art. We conclude that in intentional organizational change processes, the elimination of cues to accelerate forgetting should be used in change management practices.

    Popularity cues in online media: Theoretical and methodological perspectives in political communication research
    (2018) Porten-Cheé, Pablo; Jost, Pablo; Eilders, Christiane; Maurer, Marcus; Haßler, Jörg
    Popularitätshinweise wie Likes und Shares signalisieren grundsätzlich positive Nutzerreaktionen. Im Kontext politischer Kommunikation sind sie in ihrer aggregierten Form entweder Indikator für Relevanzzuweisungen von oder die Zustimmung zu Online-Beiträgen. Popularitätshinweise können aber auch Faktoren sein, welche die Wahrnehmung, das Verhalten und die Einstellungen des Publikums beeinflussen. Dieser Beitrag thematisiert theoretische und methodologische Aspekte für beide Perspektiven. Im Rückgriff auf Konzepte wie wahrgenommene Relevanz, Einstellungskonsonanz und Persuasion, werden zuerst die Gründe für das Liken und Sharen diskutiert. Danach wird die Wirkung von Popularitätshinweisen hauptsächlich vor dem Hintergrund der Schweigespiraltheorie und heuristischer Informationsverarbeitung erörtert. Die Informationsverarbeitung wird als Schlüsselfaktor identifiziert um zu verstehen, wie das Liken und Sharen politischer Inhalte entsteht und welche politischen Effekte Popularitätshinweise auf Individualebene hervorrufen. Die methodologische Diskussion bezieht sich auf Fragen der Datenerhebung, sowie der Validität und der Durchführbarkeit von Studien zu Popularitätshinweisen.

    Provenance Management over Linked Data Streams
    (2019) Liu, Qian; Wylot, Marcin; Le Phuoc, Danh; Hauswirth, Manfred
    Provenance describes how results are produced starting from data sources, curation, recovery, intermediate processing, to the final results. Provenance has been applied to solve many problems and in particular to understand how errors are propagated in large-scale environments such as Internet of Things, Smart Cities. In fact, in such environments operations on data are often performed by multiple uncoordinated parties, each potentially introducing or propagating errors. These errors cause uncertainty of the overall data analytics process that is further amplified when many data sources are combined and errors get propagated across multiple parties. The ability to properly identify how such errors influence the results is crucial to assess the quality of the results. This problem becomes even more challenging in the case of Linked Data Streams, where data is dynamic and often incomplete. In this paper, we introduce methods to compute provenance over Linked Data Streams. More specifically, we propose provenance management techniques to compute provenance of continuous queries executed over complete Linked Data streams. Unlike traditional provenance management techniques, which are applied on static data, we focus strictly on the dynamicity and heterogeneity of Linked Data streams. Specifically, in this paper we describe: i) means to deliver a dynamic provenance trace of the results to the user, ii) a system capable to execute queries over dynamic Linked Data and compute provenance of these queries, and iii) an empirical evaluation of our approach using real-world datasets.

    Visibility Through Information Sharing: The Role of Tweet Authors and Communication Styles in Retweeting Political Information on Twitter
    (2019) Engelmann, Ines; Kloss, Andrea; Neuberger, Christoph; Brockmann, Tobias
    If a speaker’s political message on Twitter is retweeted, both the speaker and the message become visible to a wider network of Twitter users, making the tweet actor more prominent on the Twittersphere or beyond. This study analyzes the effects of different types of tweet authors (such as politicians, journalists, economic actors, members of nonprofit interest groups, and citizens) and the communication styles of political information (affect and rationality) on the number of retweets. The potential effects of these factors are hypothesized based on the heuristic-systematic model but are also discussed in the normative context of public sphere theories. A content analysis of 4,403 tweets shows that the author types, communication styles, and their interactions affect the number of retweets. The theoretical and normative implications of these results are discussed.

    Creativity and Productivity In Product Design for Additive Manufacturing: Mechanisms and Platform Outcomes of Remixing
    (2019) Friesike, Sascha; Flath, Christoph M.; Wirth, Marco; Thiesse, Frédéric
    The present study explores the phenomenon of remixing in product design for additive manufacturing (AM). In contrast to other manufacturing techniques, AM offers unprecedented flexibility in adapting existing product designs to changing requirements. However, in order to benefit from this potential, structured design procedures and tools are indispensable. As a possible solution, online platforms for collaborative 3D model creation are increasingly implementing features for remixing, a concept describing the creation of new models on the foundation of existing design elements. Against this backdrop, the objective of this research is to provide evidence for the value of remixing as an organizational intervention for improving product design processes. To this end, we present a mixed methods approach using data from Thingiverse, the world's largest AM-related online community. In a first step, we investigate qualitative data from 81 individual remix-based designs to identify the underlying mechanisms of remixing. We identify six such mechanisms that can further be grouped by the intended outcome of the respective process (creativity-oriented: inspiration, play, learning; productivity- oriented: speed, improvement, empowerment). In a second step, we turn to a quantita- tive analysis of platform data, which indicates that remixing may lead to better design process outcomes in terms of quantity and diversity of designs. Furthermore, we find that designs created by remixing designers are significantly more often printed by com- munity members suggesting that remixing helps ensure manufacturing compatibility akin to continuous process improvement. Our research has several implications for individual designers and organizations engaging with product design for AM.

    Privacy Icons
    (2019) Efroni, Z.; Metzger, J.; Mischau, L.; Schirmbeck, Marie
    Although the institution of consent within the General Data Protection Regulation intends to facilitate the exercise of personal autonomy, reality paints a different picture. Due to a host of structural and psychological deficits, the process of giving consent is often neither informed nor does it foster self-determination. One key element in addressing this shortcoming is the visualisation of relevant information through icons. This article outlines a riskbased methodology for the selection, design and implementation of such privacy icons. It lays the groundwork for identifying risky data processing aspects as a first step in a larger project of creating a privacy icons set to accompany privacy policies. The ultimate goal of the privacy icons is to assist users in making better informed consent decisions through the visualisation of data processing aspects based on their inherent risks.
