    Who reports witnessing and performing corrections on social media in the United States, United Kingdom, Canada, and France?
    (2024) Tang, Rongwei; Vraga, Emily K.; Bode, Leticia; Boulianne, Shelley
    Observed corrections of misinformation on social media can encourage more accurate beliefs, but for these benefits to occur, corrections must happen. By exploring people’s perceptions of witnessing and performing corrections on social media, we find that many people say they observe and perform corrections across the United States, the United Kingdom, Canada, and France. We find higher levels of self-reported correction experiences

    Dynamics of opinion expression
    (2020) Gaisbauer, Felix; Olbrich, Eckehard; Banisch, Sven
    Modeling efforts in opinion dynamics have to a large extent ignored that opinion exchange between individuals can also have an effect on how willing they are to express their opinion publicly. Here, we introduce a model of public opinion expression. Two groups of agents with different opinion on an issue interact with each other, changing the willingness to express their opinion according to whether they perceive themselves as part of the majority or minority opinion. We formulate the model as a multigroup majority game and investigate the Nash equilibria. We also provide a dynamical systems perspective: Using the reinforcement learning algorithm of Q-learning, we reduce the N-agent system in a mean-field approach to two dimensions which represent the two opinion groups. This two-dimensional system is analyzed in a comprehensive bifurcation analysis of its parameters. The model identifies social-structural conditions for public opinion predominance of different groups. Among other findings, we show under which circumstances a minority can dominate public discourse.

    How journalism adapted the Internet in Germany: Results of six newsroom surveys (1997–2014)
    (2024) Neuberger, Christoph
    Based on six newsroom surveys, this article analyzes the history of digital German journalism. The surveys cover a period of 17 years (1997–2014). Periodizing the history of digital journalism into three phases, this article considers the interplay between journalism and journalism research. The results show how journalistic digital media define their role in the relationships between old media and the Internet, digital media and other outlets, and digital media and their audiences. Furthermore, the results substantiate how digital editorial staff define their journalistic identities regarding tasks, rules, and skills. During the first period (surveys conducted in 1997 and 2000), the view from old mass media to the Internet dominated, also in scholarship where the mass media paradigm was extended to the Internet. The second period (surveys conducted in 2006 and 2007) was characterized by clarifying the relationships between journalism and newly emerged outlets. These studies focused on how participative formats (such as Wikipedia and blogs) and search engines could be used for journalistic purposes without compromising quality. These new outlets were not regarded then as much of a threat. This attitude did not change during the third period (surveys conducted in 2010 and 2014). In this phase, too, the studies focused on how editorial staff utilized the ever-increasing number of social media. The six surveys’ different research interests reveal that the reviewed journalism research primarily addressed changing demands in journalistic practice. Therefore, exogenous factors (“the sector”) had a greater impact than endogenous factors (the “scholarship”) on research interests.

    EU Cyber Resilience Act: Socio-Technical and Research Challenges (Dagstuhl Seminar 24112)
    (2024) Dalla Preda, Mila; Egelman, Serge; Mandalari, Anna Maria; Stocker, Volker; Tapiador, Juan; Vallina-Rodriguez, Narseo
    This report documents the program and the outcomes of Dagstuhl Seminar "EU Cyber Resilience Act: Socio-Technical and Research Challenges" (24112). This timely seminar brought together experts in computer science, tech policy, and economics, as well as industry stakeholders, national agencies, and regulators to identify new research challenges posed by the EU Cyber Resilience Act (CRA), a new EU regulation that aims to set essential cybersecurity requirements for digital products to be permissible in the EU market. The seminar focused on analyzing the proposed text and standards for identifying obstacles in standardization, developer practices, user awareness, and software analysis methods for easing adoption, certification, and enforcement. Seminar participants noted the complexity of designing meaningful cybersecurity regulations and of aligning regulatory requirements with technological advancements, market trends, and vendor incentives, referencing past challenges with GDPR and COPPA adoption and compliance. The seminar also emphasized the importance of regulators, marketplaces, and both mobile and IoT platforms in eliminating malicious and deceptive actors from the market, and promoting transparent security practices from vendors and their software supply chain. The seminar showed the need for multi-disciplinary and collaborative efforts to support the CRA’s successful implementation and enhance cybersecurity across the EU.
