    Abstract
    Daten sind der Treibstoff der Informationsgesellschaft. Sie sind zentrale Steuerungsressourcen für Wirtschaft und Verwaltung und treiben die Algorithmen an, die die digitale Welt lenken. Darüber hinaus ist der Umgang mit Daten in der öffentlichen Verwaltung entscheidend für die demokratische Willensbildung. Nicht nur in Zeiten von Meinungsmanipulationen und Falschmeldung ist das Recht auf Zugang zu öffentlichen Informationen eine Säule des digitalen Rechtsstaats.

    Abstract
    Das Thema "Künstliche Intelligenz" (KI) wird immer wichtiger. Die Kaiserslauterer Informatikprofessorin Katharina Zweig ist Kl-Expertinund Autorin des Erklärbuchs "Ein Algorithmus hat kein Taktgefühl". Im großen RHEINPFALZ-Gespräch erläutert sie, wie Kl und Datenschutz zusammengehen können - durch dezentrales Lernen. Die Daten bleiben dadurch beim Nutzer. "KI wird insgesamt näher an uns heranrücken, darum müssen wir Betriebsräte, Schulelternbeiräte, Betroffene und Bürger befähigen, sich einmischen zu können",

    Abstract
    Dieser Beitrag behandelt den zuletzt vom W3C hervorgebrachten Standard für dezentrale Identi­fikatoren (Decentralized Identifiers, kurz: DIDs) in Bezug auf den Bereich des Forschungsdatenmanagements. Es wird dargelegt, dass die aktuell im wissenschaftlichen Publikationswesen häufig verwendeten persistenten Identifikatorensysteme (Persistent Identifiers, PIDs) wie Handle, DOI, ORCID und ROR aufgrund ihrer Zentralisierung fundamentale Probleme hinsichtlich der Daten­sicherheit, dem Datenschutz und bei der Sicherstellung der Datenintegrität aufweisen. Dem werden als mögliche Lösung das System der DIDs gegenübergestellt: eine neuartige Form von weltweit eindeutigen Identifikatoren, die durch jedes Individuum oder jede Organisation selbst generiert und auf jeder als vertrauenswürdig erachteten Plattform betrieben werden können. Blockchains oder andere Distributed-Legder-Technologien können dabei als vertrauenswürdige Datenregister fungieren, aber auch direkte Peer-to-Peer-Verbindungen, auf bestehende Internetprotokolle aufsetzende Methoden oder statische DIDs sind möglich. Neben dem Schema wird die technische Spezifikation im Sinne von Datenmodell und die Anwendung von DIDs erläutert sowie im Vergleich die Unterschiede zu zentralisierten PID-Systemen herausgestellt. Zuletzt wird der Zusammenhang mit dem zugrundeliegenden neuen Paradigma einer dezentralen Identität, der Self-Sovereign Identity, hergestellt. SSI repräsentiert ein gesamtes Ökosystem, in dem Entitäten ein kryptografisch gesichertes Vertrauensnetzwerk auf der Basis von DIDs und digitalen Identitätsnachweisen bilden, um dezentral manipulationsgesichert und datenschutzgerecht identitätsbezogene Daten auszutauschen. Zum Schluss der Abhandlung stellt der Autor fünf zuvor herausgearbeitete Anforderungen in Bezug auf eine zeitgemäße Umsetzung von persistenten Identifikatoren vor.

    Abstract
    Das Crowdsourcing-Projekt #EveryNameCounts der Arolsen Archives begann 2020 als Schulkampagne und wuchs binnen weniger Monate zu einer weltweiten Initiative. Durch die Arbeit der Freiwilligen werden Millionen von Datensätzen zu Konzentrationslagerdokumenten erfasst. Diese Datengrundlage optimiert einerseits die Suche im Online-Archiv der Arolsen Archives und macht anderseits eine auf Massendaten gestützte Forschung erst möglich. Die Arbeit der Freiwilligen geht dabei über reine Datenerhebung weit hinaus. Es entsteht ein digitales Denkmal.

    Abstract
    Wie Umfragen ergeben, ist offenbar eine Mehrheit der Bundesbürger damit einverstanden, Corona-Tracing-Apps anzuwenden, auch wenn viele erhebliche Datenschutz- und Grundrechtsfragen für die Verhaltensüberwachung noch nicht geklärt und gesichert sind. Telepolis veröffentlicht die vom Forum InformatikerInnen für Frieden und gesellschaftliche Verantwortung (FIfF) erstellte Zusammenfassung der erarbeiteten Datenschutz-Folgenabschätzung (DSFA) für die Corona-App (Zusammenfassung und DSFA (https://www.fiff.de/dsfa-corona) mit der Creative-Commons-Lizenz: Namensnennung, CC BY 4.0). Sie zeigt, dass wegen weitreichender Folgen dringender Handlungsbedarf gegeben ist, gerade weil der Druck offenbar groß ist, mit solchen technischen Überwachungsmitteln die Notstandsmaßnahmen zu lockern.

    Abstract
    When people experience major life changes, this often impacts their self-presentation, networks, and online behavior in substantial ways. To effectively study major life transitions and events, we surveyed a large U.S. sample (n = 554) to create the Major Life Events Taxonomy, a list of 121 life events in 12 categories. We then applied this taxonomy to a second large U.S. survey sample (n = 775) to understand on average how much social readjustment each event required, how likely each event was to be shared on social media with different types of audiences, and how much online network separation each involved. We found that social readjustment is positively correlated with sharing on social media, with both broad audiences and close ties as well as in online spaces separate from one's network of known ties. Some life transitions involve high levels of sharing with both separate audiences and broad audiences on social media, providing evidence for what previous research has called social media as social transition machinery. Researchers can use the Major Life Events Taxonomy to examine how people's life transition experiences relate to their behaviors, technology use, and health and well-being outcomes.

    Abstract
    To effectively manage a crisis, most decisions made by governments, organizations, communities, and individuals are based on "shared situational awareness" (SSA) derived from multiple information sources. Developing SSA depends on the alignment of mental models, which "represent our shared version of truth and reality on which we can act." Social media has facilitated public sensemaking during a crisis; however, it has also encouraged mental model dissonance, resulting in the digital destruction of mental models and undermining adequate SSA. The study is concerned with the challenges of creating SSA during the COVID-19 pandemic in Australia. This paper documents a netnography of Australian public health agencies' Facebook communication, exploring the initial impact of COVID-19 on SSA creation. Chaos theory is used as a theoretical lens to examine information perception, meaning, and assumptions relating to SSA from pre to post-pandemic periods. Our study highlights how the initial COVID-19 "butterfly effect" swamped the public health communication channel, leaving little space for other important health issues. This research contributes to information systems, information science, and communications by illustrating how the emergence of a crisis impacts social media communication, the creation of SSA, and what this means for social media adoption for crisis communication purposes.

    Abstract
    Mass media sentiment of financial news significantly influences investment decisions of investors. Hence, studying how this sentiment emerges is important. In years past, this was straightforward, often dictated by journalists who cover financial news, but this has become more complex now. In this paper, we focus on how social media sentiment affects mass media sentiment. Using data from Sina Weibo and Sina Finance (around 60 million weibos and 6.2 million news articles), we show that social media does influence mass media sentiment emergence for financial news. The sentiment consistency between social media reaction and prior news articles amplifies the persistence of mass media sentiment over time. By contrast, we found limited evidence of social media reducing the persistence of mass media sentiment over time. The results have significant implications for understanding how 2 types of media, treated separately in the literature, may be connected.

    Abstract
    Digitale Bildverarbeitung hat längst den Alltag erreicht: Automatisierte Passkontrollen, Gesichtserkennung auf dem Mobiltelefon und Apps zum Bestimmen von Pflanzen anhand von Fotos sind nur einige Beispiele für den Einsatz dieser Technologie. Digitale Bildverarbeitung zur Analyse der Inhalte von Bildern kann den Zugang zu Wissen verbessern und ist somit relevant für die Informationswissenschaft. Häufig greifen Systeme bei der Suche nach visueller Information nach wie vor auf beschreibende Metadaten zu, weil diese sprachbasierten Methoden für Massendaten meist robust funktionieren. Der Fokus liegt in diesem Beitrag auf automatischer Inhaltsanalyse von Bildern (content based image retrieval) und nicht auf reinen Metadaten-Systemen, welche Wörter für die Beschreibung von Bildern nutzen (s. Kapitel B 9 Metadaten) und somit letztlich Text-Retrieval ausführen (concept based image retrieval) (s. Kapitel C 1 Informationswissenschaftliche Perspektiven des Information Retrieval).

    Abstract
    Increasingly we live through our personal screens; we work, play, socialize, and learn digitally. The shift to remote everything during the pandemic was another step in a decades-long march toward the digitization of everyday life made possible by innovations in media, information, and communication technology. In The Digital Environment, Pablo Boczkowski and Eugenia Mitchelstein offer a new way to understand the role of the digital in our daily lives, calling on us to turn our attention from our discrete devices and apps to the array of artifacts and practices that make up the digital environment that envelops every aspect of our social experience. Boczkowski and Mitchelstein explore a series of issues raised by the digital takeover of everyday life, drawing on interviews with a variety of experts. They show how existing inequities of gender, race, ethnicity, education, and class are baked into the design and deployment of technology, and describe emancipatory practices that counter this--including the use of Twitter as a platform for activism through such hashtags as #BlackLivesMatter and #MeToo. They discuss the digitization of parenting, schooling, and dating--noting, among other things, that today we can both begin and end relationships online. They describe how digital media shape our consumption of sports, entertainment, and news, and consider the dynamics of political campaigns, disinformation, and social activism. Finally, they report on developments in three areas that will be key to our digital future: data science, virtual reality, and space exploration.

    Abstract
    "Datenrasterung". "Gläserner Versicherter". Jetzt äußert sich der Bundesdatenschutzbeauftragte zu dem ungeheuerlichen Vorgang. Es ist schlimmer, als bisher angenommen. Und es zeigt, welche Manöver die Bundesregierung unternommen hat, um Datenschutzrechte von 73 Millionen gesetzlich Versicherter auszuhebeln, ohne dass die betroffenen Bürger selbst davon erfahren. Aber das ist, wie sich jetzt herausstellt, noch nicht alles. Am Montag hatte Telepolis aufgedeckt, dass CDU/CSU und SPD mit Hilfe eines von der Öffentlichkeit unbemerkten Änderungsantrags zum EPA-Gesetz (Elektronische Patientenakte) das erst im November im Digitale-Versorgung-Gesetz (DVG) (Wie man Datenschutz als Versorgungsinnovation framet) festgeschriebene Einwilligungserfordernis zur individualisierten Datenauswertung durch die Krankenkassen still und leise wieder beseitigt haben (zur genauen Einordnung des aktuellen Vorgangs: EPA-Datengesetz - Sie haben den Affen übersehen).

Inside Facebook: Wie hinter verschlossenen Türen über das Schicksal von Milliarden Usern entschieden wird. Was auf uns zukommt: Mark Zuckerbergs Pläne für die Zukunft seines Unternehmens und die unserer Gesellschaft. Vom Start-up zur Weltmacht: Die dramatische Firmengeschichte von Facebook zeigt, wie aus dem Konzern das international einflussreiche Tech-Imperium werden konnte, von dem es heute heißt, es bedrohe die Demokratie. Das sich gegen immer lautere Stimmen behaupten muss, die fordern, der Konzern habe zu viel Einfluss und gehöre zerschlagen. Das mit über 1,7 Milliarden täglichen Zugriffen von weltweiten Nutzern über enorme Daten-Vorräte und eine Macht verfügt, die ihresgleichen sucht. Eine Macht, für die der Konzern heute immer deutlicher zur Rechenschaft gezogen wird. Facebook, WhatsApp, Instagram: Wie das Unternehmen sich von einer Social-Media-Plattform zu einem der einflussreichsten Unternehmen unserer Zeit wandeln konnte. Mit welchen skrupellosen Strategien es Mark Zuckerberg gelang, seine Mitbewerber im Kampf um die Vormachtstellung im Silicon Valley auszubooten.
