- Abstract
- Browsererweiterungen zum Schutz vor Tracking stellen beliebte Werkzeuge zum Schutz der Privatsphäre von Nutzerinnen und Nutzern dar. Ihre tatsächliche Effektivität ist in hohem Maße von ihrer Usability abhängig, da diese bestimmt, in welchem Ausmaß diese Werkzeuge effektiv, effizient und zufriedenstellend genutzt werden können. Die vorliegende Untersuchung prüft die Gebrauchstauglichkeit vier solcher Browsererweiterungen mit Hilfe von Benutzertests. Die Ergebnisse zeigen, dass die Add-ons auch heutzutage noch eine Vielzahl an Usability-Mängeln aufweisen. Kernprobleme stellen insbesondere die mangelnde Verständlichkeit und die fehlende Führung und Unterstützung der Nutzenden dar.

- Abstract
- The extant literature demonstrates that the age-related digital divide prevents older adults from enhancing their quality of life. To bridge this gap and promote active aging, this study explores the interplay between social networks and older adults' use of information and communication technology (ICT). Using an action-oriented field research approach, we offered technical help (29 help sessions) to older adult participants recruited from western China. Then, we conducted content analysis to examine the obtained video, audio, and text data. Our results show that, first, different types of social networks significantly influence older adults' ICT use in terms of digital skills, engagement, and attitudes; however, these effects vary from person to person. In particular, our results highlight the crucial role of a stable and long-term supportive social network in learning and mastering ICT for older residents. Second, technical help facilitates the building and reinforcing of such a social network for the participants. Our study has strong implications in that policymakers can foster the digital inclusion of older people through supportive social networks.

- Abstract
- The purpose of this study is to investigate the validity of tweets about scientific publications as an indicator of societal impact by measuring the degree to which the publications are tweeted beyond academia. We introduce methods that allow for using a much larger and broader data set than in previous validation studies. It covers all areas of research and includes almost 40 million tweets by 2.5 million unique tweeters mentioning almost 4 million scientific publications. We find that, although half of the tweeters are external to academia, most of the tweets are from within academia, and most of the external tweets are responses to original tweets within academia. Only half of the tweeted publications are tweeted outside of academia. We conclude that, in general, the tweeting of scientific publications is not a valid indicator of the societal impact of research. However, publications that continue being tweeted after a few days represent recent scientific achievements that catch attention in society. These publications occur more often in the health sciences and in the social sciences and humanities.
