... A promising methodology that allows researchers to obtain insights into adolescents' social media content are social media data donation packages (Araujo et al., 2022;van Driel et al., 2022). Data donation packages (DDPs) are the personal archives of social media users that contain all their social media data stored by the platform in question. ...

... Nevertheless, this approach clearly tells us that -regardless of the channel through which the information was received -traditional media played a crucial role in the information diet of Germans, Pakistanis, and Indonesians at the time of the data collection. As such, we found a cross-national stable importance of traditional news media in times of crisis, which extends the existing knowledge of similar findings in the Western context (e.g., Vermeer et al., 2022) based on insights from two Global South countries. ...

... Yet, we have comparatively little evidence of this. Recently, Trilling et al. (2022) examined news sharing behaviour in four multi-party systems covering significant variation across countries in Europe. They found that, despite their different media systems and political systems, the underlying processes and sharing patterns in the four countries are remarkably similar. ...

... Based on the data obtained, "Privacy and data protection" showed a strong correlation with "Safe internet use". The developed instrument can therefore also be considered a useful and relevant research tool for the study of risk practices associated with the dimensions obtained in the CFA, such as personal data protection [49,50], communication risks with people and entities [51], and behavioral risks [5]. These three categories are among some that the OECD has classified as potential risks on the Internet, which are also very much in line with elements of Livingstone's and Stoilova's [52] "4Cs" risk proposal. ...

... The Facebook Ad Library is an open to the public-tool created by Facebook in their attempt to make their platform and the advertisements published on it more transparent [Fa22c]. According to Leerssen et al. [LDHV21], the Facebook Ad library documents a selection of ads that appear on Facebook, and although it has been criticized for data not being granular enough, it does constitute a step towards advertising transparency. For this paper, a total of one hundred ads -ten ads per every of the ten companies -were collected using the Facebook Ads library for the month of February 2022 in Germany, creating a selection of companies that were running several advertisements. ...

... Due to the inherent risks of relying on the goodwill of commercial companies for access to societally relevant data, there have been calls and proposals for different models of access to such data (Breuer et al., 2020). One approach that has gained traction recently is collaborating with platform users (Halavais, 2019) through a model typically labeled as "data donation" (Araujo et al., 2021;Boeschoten et al., 2020). When sharing their data with researchers, platform users can and should be given the opportunity to explore and understand their own data. ...

... Extant research seems to present a clear picture of a positive relationship between offline and online news consumption and political knowledge (e.g., Kenski & Stroud, 2006;Ohme, 2020;Van Erkel & Van Aelst, 2021;Wei & Lo, 2008). However, these results are being challenged by recent empirical findings indicating that higher news use does not always lead to greater knowledge about current political events (e.g., Castro et al., 2021;Dimitrova et al., 2011;Moeller & de Vreese, 2019;Strömbäck et al., 2018). While research on direct democratic referendum campaigns has intensified in recent years, most of these studies have focused on citizens' opinion formation processes (for an overview, see Kriesi, 2011), whereas research on media use and knowledge about, and participation in, referendums remains very scarce. ...

... Blue Feed Red Feed, 1 GroundNews 2 ), while in direct communication many other organisations have expressed their intention to incorporate diversity considerations in their future products. Although these attempts are still in their infancy, diversity is becoming increasingly prominent in news recommender design (Bernstein et al., 2021) and recent research indicates that more diverse NRSs do not necessarily impede user utility (Heitz et al., 2022). ...

... Even though the intentional spread of mediated falsehoods has been evident in political discourse for decades, scholars have declared this the 'age of disinformation' (Carmi et al., 2020). Digital information environments have facilitated its extensive, unrestrained and sometimes systematic distribution (Bradshaw et al., 2020), which is often emanating from populist groups (Hameleers and de Vreese, 2021) and, more recently, has become an elementary component of hybrid warfare (Arcos et al., 2022). Simultaneously, concerns about the trustworthiness of media are rising, while political and mediated discourses about disinformation make it seem like trustworthy information is difficult to find (Allcott and Gentzkow, 2017). ...

... To continue to fulfil their role, media actors need the technological skills and tools necessary to evaluate how the technologies they use relate to editorial values. As the discussion on metrics has demonstrated, this requires a better understanding of whether, and if so how, specific technologies affect editorial values (Bernstein et al., 2020;CoE, 2019;Vrijenhoek et al., 2020). Diakopoulous, for example, argues media organisations can verify whether an algorithm lines up with their editorial mission by formulating and then testing a hypothesis on the way in which an algorithm impacts an editorial value (Diakopoulos, 2019). ...
