    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.

    “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.

    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.

    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.

    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.

    Audit - and then what? A roadmap for digitization of learning factories
    (2019) Ullrich, André; Enke, Judith; Teichmann, Malte; Kreß, Antonio; Gronau, Norbert
    Current trends such as digital transformation, Internet of Things, or Industry 4.0 are challenging the majority of learning factories. Regardless of whether a conventional learning factory, a model factory, or a digital learning factory, traditional approaches such as the monotonous execution of specific instructions don‘t suffice the learner’s needs, market requirements as well as especially current technological developments. Contemporary teaching environments need a clear strategy, a road to follow for being able to successfully cope with the changes and develop towards digitized learning factories. This demand driven necessity of transformation leads to another obstacle: Assessing the status quo and developing and implementing adequate action plans. Within this paper, details of a maturity-based audit of the hybrid learning factory in the Research and Application Centre Industry 4.0 and a thereof derived roadmap for the digitization of a learning factory are presented.

    Unexpected Inferences from Sensor Data. A Hidden Privacy Threat in the Internet of Things
    (Springer International Publishing, 2019) Kröger, Jacob; Strous, Leon; Cerf, Vinton G.
    A growing number of sensors, embedded in wearables, smart electric meters and other connected devices, is surrounding us and reaching ever deeper into our private lives. While some sensors are commonly regarded as privacy-sensitive and always require user permission to be activated, others are less protected and less worried about. However, experimental research findings indicate that many seemingly innocuous sensors can be exploited to infer highly sensitive information about people in their vicinity. This paper reviews existing evidence from the literature and discusses potential implications for consumer privacy. Specifically, the analysis reveals that certain insufficiently protected sensors in smart devices allow inferences about users’ locations, activities and real identities, as well as about their keyboard and touchscreen inputs. The presented findings call into question the adequacy of current sensor access policies. It is argued that most data captured by smart consumer devices should be classified as highly sensitive by default. An introductory overview of sensors commonly found in these devices is also provided, along with a proposed classification scheme.

    Subject-oriented learning - A new perspective for vocational training in learning factories
    (2019) Teichmann, Malte; Ullrich, André; Gronau, Norbert
    The transformation to a digitized company changes not only the work but also social context for the employees and requires inter alia new knowledge and skills from them. Additionally, individual action problems arise. This contribution proposes the subject-oriented learning theory, in which the employees´ action problems are the starting point of training activities in learning factories. In this contribution, the subject-oriented learning theory is exemplified and respective advantages for vocational training in learning factories are pointed out both theoretically and practically. Thereby, especially the individual action problems of learners and the infrastructure are emphasized as starting point for learning processes and competence development.

    Surfing in sound: Sonification of hidden web tracking
    (Georgia Institute of Technology, 2019) Lutz, Otto Hans-Martin; Kröger, Jacob; Schneiderbauer, Manuel; Hauswirth, Manfred
    Web tracking is found on 90% of common websites. It allows online behavioral analysis which can reveal insights to sensitive personal data of an individual. Most users are not aware of the amout of web tracking happening in the background. This paper contributes a sonification-based approach to raise user awareness by conveying information on web tracking through sound while the user is browsing the web. We present a framework for live web tracking analysis, conversion to Open Sound Control events and sonification. The amount of web tracking is disclosed by sound each time data is exchanged with a web tracking host. When a connection to one of the most prevalent tracking companies is established, this is additionally indicated by a voice whispering the company name. Compared to existing approaches on web tracking sonification, we add the capability to monitor any network connection, including all browsers, applications and devices. An initial user study with 12 participants showed empirical support for our main hypothesis: exposure to our sonification significantly raises web tracking awareness.

    Mediated democracy – Linking digital technology to political agency
    (2019) Hofmann, Jeanette
    Although the relationship between digitalisation and democracy is subject of growing public attention, the nature of this relationship is rarely addressed in a systematic manner. The common understanding is that digital media are the driver of the political change we are facing today. This paper argues against such a causal approach und proposes a co-evolutionary perspective instead. Inspired by Benedict Anderson's "Imagined Communities" and recent research on mediatisation, it introduces the concept of mediated democracy. This concept reflects the simple idea that representative democracy requires technical mediation, and that the rise of modern democracy and of communication media are therefore closely intertwined. Hence, mediated democracy denotes a research perspective, not a type of democracy. It explores the changing interplay of democratic organisation and communication media as a contingent constellation, which could have evolved differently. Specific forms of communication media emerge in tandem with larger societal formations and mutually enable each other. Following this argument, the current constellation reflects a transformation of representative democracy and the spread of digital media. The latter is interpreted as a "training ground" for experimenting with new forms of democratic agency.
