- ItemCreativity and Productivity In Product Design for Additive Manufacturing: Mechanisms and Platform Outcomes of Remixing(2019) Friesike, Sascha; Flath, Christoph M.; Wirth, Marco; Thiesse, FrédéricThe 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.
- ItemLearning via assistance systems in industrial manufacturing. An experimental study in an Industry 4.0 environment(2023) Wotschack, Philip; Vladova, Gergana; De Paiva Lareiro, Patricia; Thim, ChristofPurpose: The purpose of this paper is to investigate how learning solely via an assistance system influences work performance compared with learning with a combination of an assistance system and additional training. While the training literature has widely emphasised the positive role of on-the-job training, particularly for groups that are often underrepresented in formalised learning situations, organisational studies have stressed the risks that emerge when holistic process knowledge is lacking and how this negatively affects work performance. This study aims at testing these negative effects within an experimental design.
- ItemOnline Civic Intervention: A New Form of Political Participation Under Conditions of a Disruptive Online Discourse(2020) Porten-Cheé, Pablo; Kunst, Marlene; Emmer, MartinIn the everyday practice of online communication, we observe users deliberately reporting abusive content or opposing hate speech through counterspeech, while at the same time, online platforms are increasingly relying on and supporting this kind of user action to fight disruptive online behavior. We refer to this type of user engagement as online civic intervention (OCI) and regard it as a new form of user-based political participation in the digital sphere that contributes to an accessible and reasoned public discourse. Because OCI has received little scholarly attention thus far, this article conceptualizes low- and high-threshold types of OCI as different kinds of user responses to common disruptive online behavior such as hate speech or hostility toward the media. Against the background of participation research, we propose a theoretically grounded individual-level model that serves to explain OCI.
- ItemPerspektivwechsel: Migrationsberichterstattung in ausgewählten afrikanischen Ländern und Deutschland aus Migrant*innensicht(2020) Zappe, Anna-Carina; Bastian, Mariella; Leißner, Laura; Henke, Jakob; Fengler, Susanne; Gehrau, Volker; Waldherr, Annie; Scholl, Armin; Deutsche Gesellschaft Für Publizistik- Und Kommunikationswissenschaft E.V.Since 2015, migration and immigration have been relevant topics of political debate in Germany. Therefore, various communication studies researched the media reporting on these issues and examined how it affects the perception of migrants within the German population (e.g. Arlt & Wolling, 2017). In distinction to this, the present study addresses the question of how migrants themselves receive migration reporting, how they perceive it, and how it shapes their personal migration and integration actions. We conducted two focus group discussions with migrants from Sub-Saharan Africa. The participants discussed both the reception and evaluation of migration reporting in their country of origin and in Germany. The results show that the topic of migration was hardly reported in the countries of origin, which is why personal migration decisions were more influenced by interpersonal communication. In Germany, the African participants perceive media reports about migration issues as too one-sided and as reduced to the sub-themes of poverty and war.
- ItemHow Right-Wing Populist Comments Affect Online Deliberation on News Media Facebook Pages(2022) Thiele, Daniel; Turnšek, TjašaRight‐wing populist user comments on social media are said to impair online deliberation. Right‐wing populism’s anti‐pluralist and conflict‐centered message might hinder deliberative debates, which are characterized by reciprocity, arguments, sourcing, politeness, and civility. Although right‐wing populism has been found to foster user interaction on social media, few empirical studies have examined its impact on the scope and deliberative quality of user debates. This study focuses on debates on 10 Facebook pages of Austrian and Slovenian mass media during the so‐called “refugee crisis” of 2015–2016. Proceeding in two steps, we first analyze how right‐wing populist user comments affect the number of reply comments using a dataset of N = 281,115 Facebook comments and a validated, automated content analysis. In a second step, we use a manual, quantitative content analysis to investigate how right‐wing populist comments affect the deliberative quality of N = 1,413 reply comments. We test five hypotheses in carefully modeled regression analyses. Our findings show that right‐wing populist comments trigger replies but impair their deliberative quality. People‐centric comments decrease the probability of arguments in replies, and anti‐immigrant comments spark incivility. Countering populism further increases impoliteness. We discuss our findings against the backdrop of an increasingly uncivil online public sphere and populism’s ambivalent relationship with democracy.
