- ItemActive Social Media Use and Its Impact on Well-being: An Experimental Study on the Effects of Posting Pictures on Instagram(2023) Krause, Hannes-Vincent; große Deters, Fenne; Baumann, Annika; Krasnova, HannaActive use of social networking sites (SNSs) has long been assumed to benefit users’ well-being. However, this established hypothesis is increasingly being challenged, with scholars criticizing its lack of empirical support and the imprecise conceptualization of active use. Nevertheless, with considerable heterogeneity among existing studies on the hypothesis and causal evidence still limited, a final verdict on its robustness is still pending. To contribute to this ongoing debate, we conducted a week-long randomized control trial with N = 381 adult Instagram users recruited via Prolific. Specifically, we tested how active SNS use, operationalized as picture postings on Instagram, affects different dimensions of well-being. The results depicted a positive effect on users’ positive affect but null findings for other well-being outcomes. The findings broadly align with the recent criticism against the active use hypothesis and support the call for a more nuanced view on the impact of SNSs.
- ItemArticulation Work and Tinkering for Fairness in Machine Learning(2024) Fahimi, Miriam; Russo, Mayra; Scott, Kristen M.; Vidal, Maria-Esther; Berendt, Bettina; Kinder-Kurlanda, KatharinaThe field of fair AI aims to counter biased algorithms through computational modelling. However, it faces increasing criticism for perpetuating the use of overly technical and reductionist methods. As a result, novel approaches appear in the field to address more socially-oriented and interdisciplinary (SOI) perspectives on fair AI. In this paper, we take this dynamic as the starting point to study the tension between computer science (CS) and SOI research. By drawing on STS and CSCW theory, we position fair AI research as a matter of 'organizational alignment': what makes research 'doable' is the successful alignment of three levels of work organization (the social world, the laboratory, and the experiment). Based on qualitative interviews with CS researchers, we analyze the tasks, resources, and actors required for doable research in the case of fair AI. We find that CS researchers engage with SOI research to some extent, but organizational conditions, articulation work, and ambiguities of the social world constrain the doability of SOI research for them. Based on our findings, we identify and discuss problems for aligning CS and SOI as fair AI continues to evolve.
- ItemDigital Sovereignty in times of AI: between perils of hegemonic agendas and possibilities of alternative approaches(2024) Costa Barbosa, Alexandre; Herlo, Bianca; Joost, GescheAlthough it has been on the agenda for over a decade, the importance of digital sovereignty has recently increased. Nations-states worldwide have developed policies or expressed through speeches the need to safeguard their interests in the digital realm. The current technological frontier is artificial intelligence (AI). Hence, digital sovereignty agendas now encompass the complexities introduced by AI. This article explores contemporary discourses on digital sovereignty, highlighting how different ideological positions shape these conversations. Current discussions reveal a multifaceted field where sovereignty is interpreted through varied lenses, directly influencing the governance of technologies such as AI. Predominant perspectives often focus on state, market, or individual sovereignty over data, algorithms, and AI models. However, through document and discourse analysis, the article examines alternative approaches such as sustainable, grassroots, and feminist digital sovereignties and those led by communities or indigenous peoples. These visions challenge the mainstream by emphasizing autonomy, inclusion, and sustainability in managing critical AI resources, including computing, databases, data, and algorithm governance. By analyzing these approaches, the article identifies principles that can foster more diverse, democratic, and virtuous AI development. Finds points out that participatory governance and the development of emancipatory technologies are essential to navigating the ethical and practical issues that emerge at the intersection of digital sovereignty and AI. In a normative way, the article concludes by reflecting on how these alternative discourses can influence the future of AI, pointing to paths that could lead to a more inclusive and sovereign AI development aligned with collective and environmental values. Future research could explore how these sovereignty conceptions catalyze an AI's evolution to align with collective digital self-determination and more conscious and equitable resource management practices.
- ItemDo All Roads Lead to Rome? Exploring the Relationship Between Social Referrals, Referral Propensity and Stickiness to Video-on-Demand Websites(2020) Köster, Antonia; Matt, Christian; Hess, ThomasContent website providers have two main goals: They seek to attract consumers and to keep them on their websites as long as possible. To reach potential consumers, they can utilize several online channels, such as paid search results or advertisements on social media, all of which usually require a substantial marketing budget. However, with rising user numbers of online communication tools, website providers increasingly integrate social sharing buttons on their websites to encourage existing consumers to facilitate referrals to their social networks. While little is known about this social form of guiding consumers to a content website, the study proposes that the way in which consumers reach a website is related to their stickiness to the website and their propensity to refer content to others. By using a unique clickstream data set of a video-on-demand website, the study compares consumers referred by their social network to those consumers arriving at the website via organic search or social media advertisements in terms of stickiness to the website (e.g., visit length, number of page views, video starts) and referral likelihood. The results show that consumers referred through social referrals spend more time on the website, view more pages, and start more videos than consumers who respond to social media advertisements, but less than those coming through organic search. Concerning referral propensity, the results indicate that consumers attracted to a website through social referrals are more likely to refer content to others than those who came through organic search or social media advertisements. The study offers direct insights to managers and recommends an increase in their efforts to promote social referrals on their websites.
- ItemE-participation in municipalities services: A systematic literature review of evaluation approaches(2025) Ietto, Beatrice; Ullrich, AndréEvaluating e-participation initiatives is critical to understanding their impact on democratic processes, public policy, and societal welfare. However, existing evaluation frameworks often neglect the complexities of multi-stakeholder environments. Through a systematic literature review of 47 empirical cases, this gap is addressed by developing a typology of evaluation categories (supply-side, user activity, public value, political, and societal impact) and a comprehensive evaluation framework that accounts for the diverse objectives of all the involved stakeholders — technology providers, local governments, and citizens. By integrating short-term engagement metrics and long-term societal outcomes, the framework ensures more accurate assessments of e-participation success. We argue that adopting a multi- stakeholder approach in evaluation can significantly enhance the effectiveness, inclusivity, and sustainability of e-participation initiatives. Our findings challenge current evaluation practices and provide guidance for practitioners aiming to optimize governance, improve public services, and empower citizens through more robust evaluation methods. This study lays the foundation for systematic evaluation methods that consider stakeholder objectives, crucial for advancing e- participation research, and policy.
- ItemMainstreaming civic tech and citizen sensing: a research agenda on co-creation methods, data interfaces, and impact pathways(2023) Raetzsch, Christoph; Hamm, Andrea; Shibuya, YuyaIn this perspective article, we propose an interdisciplinary research agenda that addresses citizen science approaches embedded in civic tech initiatives and citizen sensing scenarios. The proposed agenda builds on the multi-level perspective framework (Geels, 2004; Geels, 2019) to inform research on how such ‘niche innovations’ like citizen sensing become mainstreamed in broader socio-technical systems and modes of governance. To support research across use case scenarios and make analyses more comparable internationally, we identify three core areas of interdisciplinary future research and practice development: 1) uses of co-creation methods to develop project objectives and align stakeholders; 2) designs of interfaces for gathering, communicating, and archiving civic data for different types of users; and 3) modeling impact pathways of individual projects that include civic tech activists and citizen scientists, academic researchers, journalists, and policymakers. For impact pathways, we highlight the importance of collaborations with data-driven approaches in journalism.
- ItemRethinking geographies of sovereignty: Towards a conceptual framework of situated sovereignty(2023) Lange, Bastian; Pütz, Marco; Herlo, BiancaWe engage with debates on shifting geographies of sovereignty in the digital age by providing a conceptual framework for “situated sovereignty”. Our contribution draws on a review of the scholarly literature and current sovereignty practices. We aim to move beyond state-centred and territorial understandings of sovereignty. A common discussion is the necessity of reconfiguring notions of sovereignty. However, hardly any studies have discussed the sociospatial configurations of practising sovereignty in the digital present. We conceptualise practices of sovereignty along intersecting strands of scholarly literature that have scarcely been related, drawing from political geography, science and technology studies, and critical digitalisation studies. Reviewing the literature, we identify three fields framing current practices of sovereignty—(i) state and territory, (ii) civic engagement, and (iii) digitalisation—based on which we develop a conceptual framework of situated sovereignty. Our framework addresses the situated role of sovereignty practices from a spatial point of view. We propose pragmatism, legitimacy, and governance as three analytical themes for better understanding current and future shifting geographies of sovereignty and enhancing sovereignty studies.
- ItemThe differential effects of self-view in virtual meetings when speaking vs. listening(2024) Abramova, Olga; Gladkaya, Margarita; Krasnova, HannaWith the surging reliance on videoconferencing tools, users may find themselves staring at their reflections for hours a day. We refer to this phenomenon as self-referential information (SRI) consumption and examine its consequences and the mechanism behind them. Building on self-awareness research and the strength model of self-control, we argue that SRI consump tion heightens the state of self-awareness and thereby depletes participants’ mental resources, eventually undermining virtual meeting (VM) outcomes. Our findings from a European employee sample revealed contrary effects of SRI consumption across speaker vs listener roles. Engagement with self-view is positively associated with self-awareness, which, in turn, is negatively related to satisfaction with VM process, perceived productivity, and enjoyment. Looking at the self while listening to others exhibits adverse direct and indirect (via self- awareness) effects on VM outcomes. However, looking at the self when speaking exhibits positive direct effects on satisfaction with VM process and enjoyment.
