BT - a systematic literature review and ethical-legal discussion T2 - Wirtschaftsinformatik 2023 Proceedings N2 - Disinformation campaigns spread rapidly through social media and can cause serious harm, especially in crisis situations, ranging from confusion about how to act to a loss of trust in government institutions. Therefore, the prevention of digital disinformation campaigns represents an important research topic. However, previous research in the field of information systems focused on the technical possibilities to detect and combat disinformation, while ethical and legal perspectives have been neglected so far. In this article, we synthesize previous information systems literature on disinformation prevention measures and discuss these measures from an ethical and legal perspective. We conclude by proposing questions for future research on the prevention of disinformation campaigns from an IS, ethical, and legal perspective. In doing so, we contribute to a balanced discussion on the prevention of digital disinformation campaigns that equally considers technical, ethical, and legal issues, and encourage increased interdisciplinary collaboration in future research.

Participants completed measures of SII use, thin- and muscular-ideal internalization, valuing appearance over competence, and body surveillance. Structural equation modeling revealed that SII use was associated with body image concerns for boys and girls via different routes. Specifically, female SII use was indirectly associated with higher body surveillance via thin-ideal internalization and subsequent valuing appearance over competence for girls. For both girls and boys, male SII use was indirectly linked to higher body surveillance via muscular-ideal internalization.

Therefore, if we wish to understand the needs of modern society better and want to protect it from new threats, we urgently need more robust, higher-quality natural language processing (NLP) applications that can recognize such necessities and menaces automatically, by analyzing uncensored texts. Unfortunately, most NLP programs today have been created for standard language, as we know it from newspapers, or, in the best case, adapted to the specifics of English social media. This thesis reduces the existing deficit by entering the new frontier of German online communication and addressing one of its most prolific forms—users’ conversations on Twitter. In particular, it explores the ways and means by how people express their opinions on this service, examines current approaches to automatic mining of these feelings, and proposes novel methods, which outperform state-of-the-art techniques. For this purpose, I introduce a new corpus of German tweets that have been manually annotated with sentiments, their targets and holders, as well as lexical polarity items and their contextual modifiers. Using these data, I explore four major areas of sentiment research: (i) generation of sentiment lexicons, (ii) fine-grained opinion mining, (iii) message-level polarity classification, and (iv) discourse-aware sentiment analysis. In the first task, I compare three popular groups of lexicon generation methods: dictionary-, corpus-, and word-embedding–based ones, finding that dictionary-based systems generally yield better polarity lists than the last two groups. Apart from this, I propose a linear projection algorithm, whose results surpass many existing automatically-generated lexicons. Afterwords, in the second task, I examine two common approaches to automatic prediction of sentiment spans, their sources, and targets: conditional random fields (CRFs) and recurrent neural networks, obtaining higher scores with the former model and improving these results even further by redefining the structure of CRF graphs. When dealing with message-level polarity classification, I juxtapose three major sentiment paradigms: lexicon-, machine-learning–, and deep-learning–based systems, and try to unite the first and last of these method groups by introducing a bidirectional neural network with lexicon-based attention. Finally, in order to make the new classifier aware of microblogs' discourse structure, I let it separately analyze the elementary discourse units of each tweet and infer the overall polarity of a message from the scores of its EDUs with the help of two new approaches: latent-marginalized CRFs and Recursive Dirichlet Process. N2 - Die enorme Popularität von Online-Kommunikationsdiensten in den letzten Jahrzehnten hat nicht unser Leben massiv geändert (sodass Nachrichten sich wie Fegefeuer übers Internet ausbreiten, Präsidenten ihre Entscheidungen auf Twitter ankündigen, und Ergebnisse politischer Wahlen auf Facebook entschieden werden) sondern auch zu einem dramatischen Anstieg der Datenmenge geführt, die über solche Plattformen ausgetauscht werden. Deswegen braucht man heutzutage dringend zuverlässige, qualitätvolle NLP-Programme, um neue gesellschaftliche Bedürfnisse und Risiken in unzensierten Nutzernachrichten automatisch erkennen und abschätzen zu können. Leider sind die meisten modernen NLP-Anwendungen entweder auf die Analyse der Standardsprache (wie wir sie aus Zeitungstexten kennen) ausgerichtet oder im besten Fall an die Spezifika englischer Social Media angepasst. Diese Dissertation reduziert den bestehenden Rückstand, indem sie das "Neuland" der deutschen Online-Kommunikation betritt und sich einer seiner produktivsten Formen zuwendet—den User-Diskussionen auf Twitter. Diese Arbeit erforscht insbesondere die Art und Weise, wie Leute ihre Meinungen auf diesem Online-Service äußern, analysiert existierende Verfahren zur automatischen Erkennung ihrer Gefühle und schlägt neue Verfahren vor, die viele heutige State-of-the-Art-Systeme übertreffen. Zu diesem Zweck stelle ich ein neues Korpus deutscher Tweets vor, die manuell von zwei menschlichen Experten mit Sentimenten (polaren Meinungen), ihren Quellen (sources) und Zielen (targets) sowie lexikalischen polaren Termen und deren kontextuellen Modifizierern annotiert wurden. Mithilfe dieser Daten untersuche ich vier große Teilgebiete der Sentimentanalyse: (i) automatische Generierung von Sentiment-Lexika, (ii) aspekt-basiertes Opinion-Mining, (iii) Klassifizierung der Polarität von ganzen Nachrichten und (iv) diskurs-bewusste Sentimentanalyse. In der ersten Aufgabe vergleiche ich drei populäre Gruppen von Lexikongenerierungsmethoden: wörterbuch-, corpus- und word-embedding-basierte Verfahren, und komme zu dem Schluss, dass wörterbuch-basierte Ansätze generell bessere Polaritätslexika liefern als die letzten zwei Gruppen. Abgesehen davon, schlage ich einen neuen Linearprojektionsalgorithmus vor, dessen Resultate deutlich besser als viele automatisch generierte Polaritätslisten sind. Weiterhin, in der zweiten Aufgabe, untersuche ich zwei gängige Herangehensweisen an die automatische Erkennung der Textspannen von Sentimenten, Sources und Targets: Conditional Random Fields (CRFs) und rekurrente neuronale Netzwerke. Ich erziele bessere Ergebnisse mit der ersten Methode und verbessere diese Werte noch weiter durch alternative Topologien der CRF-Graphen. Bei der Analyse der Nachrichtenpolarität stelle ich drei große Sentiment-Paradigmen gegenüber: lexikon-, Machine-Learning–, und Deep-Learning–basierte Systeme, und versuche die erste und die letzte dieser Gruppen in einem Verfahren zu vereinigen, indem ich eine neue neuronale Netzwerkarchitektur vorschlage: bidirektionales rekurrentes Netzwerk mit lexikon-basierter Attention (LBA). Im letzten Kapitel unternehme ich einen Versuch, die Prädiktion der Gesamtpolarität von Tweets über die Diskursstruktur der Nachrichten zu informieren. Zu diesem Zweck wende ich den vorgeschlagenen LBA-Klassifikator separat auf jede einzelne elementare Diskurs-Einheit (EDU) eines Microblogs an und induziere die allgemeine semantische Ausrichtung dieser Nachricht mithilfe von zwei neuen Methoden: latenten marginalisierten CRFs und rekursivem Dirichlet-Prozess.

Engaging media theory, critical race theory, and Black feminist theory, as well as contemporary feminist movements, this book argues that digital feminist interventions map themselves onto and make use of the multiplicity and ambiguity of digital spaces to question presentist and fixed notions of the internet as a white space and technologies in general as objective or universal. Understanding these frameworks as colonial constructions of the human, identity is traced to a socio-material condition that emerges with the modernity/colonialism binary. In the colonial moment, race and gender become the reasons for, as well as the effects of, technologies of identification, and thus need to be understood as and through technologies. What Deleuze has called modulation is not a present modality of control, but is placed into a longer genealogy of imperial division, which stands in opposition to feminist, queer, and anti-racist activism that insists on non-modular solidarities across seeming difference. At its heart, Feminist Solidarities after Modulation provides an analysis of contemporary digital feminist solidarities, which not only work at revealing the material histories and affective ""leakages"" of modular governance, but also challenges them to concentrate on forms of political togetherness that exceed a reductive or essentialist understanding of identity, solidarity, and difference.

However, the same users readily disclose their data when requested by an online service. The dichotomy between privacy attitude and actual behaviour is commonly referred to as the “privacy paradox”. Over twenty years of research were not able to provide one comprehensive explanation for the paradox and seems even further from providing actual means to overcome the paradox. We argue that the privacy paradox is not just an instantiation of the attitude-behaviour gap. Instead, we introduce a new paradigm explaining the paradox as the result of attitude-intention and intentionbehaviour gaps. Historically, motivational goal-setting psychologists addressed the issue of intentionbehaviour gaps in terms of the Rubicon Model of Action Phases and argued that commitment and volitional strength are an essential mechanism that fuel intentions and translate them into action. Thus, in this study we address the privacy paradox from a motivational psychological perspective by developing two interventions on Facebook and assess whether the 287 participants of our online experiment actually change their privacy behaviour. The results demonstrate the presence of an intentionbehaviour gap and the efficacy of our interventions in reducing the privacy paradox.

However, the misuse by spammers, haters, and trolls raises doubts about whether the benefits justify the costs of the time-consuming content moderation. As a consequence, many platforms limited or even shut down comment sections completely. In this thesis, we present deep learning approaches for comment classification, recommendation, and prediction to foster respectful and engaging online discussions. The main focus is on two kinds of comments: toxic comments, which make readers leave a discussion, and engaging comments, which make readers join a discussion. First, we discourage and remove toxic comments, e.g., insults or threats. To this end, we present a semi-automatic comment moderation process, which is based on fine-grained text classification models and supports moderators. Our experiments demonstrate that data augmentation, transfer learning, and ensemble learning allow training robust classifiers even on small datasets. To establish trust in the machine-learned models, we reveal which input features are decisive for their output with attribution-based explanation methods. Second, we encourage and highlight engaging comments, e.g., serious questions or factual statements. We automatically identify the most engaging comments, so that readers need not scroll through thousands of comments to find them. The model training process builds on upvotes and replies as a measure of reader engagement. We also identify comments that address the article authors or are otherwise relevant to them to support interactions between journalists and their readership. Taking into account the readers' interests, we further provide personalized recommendations of discussions that align with their favored topics or involve frequent co-commenters. Our models outperform multiple baselines and recent related work in experiments on comment datasets from different platforms. N2 - Kommentarspalten von Online-Nachrichtenplattformen sind ein essentieller Ort, um Meinungen zu äußern und politische Themen zu diskutieren. Der Missbrauch durch Trolle und Verbreiter von Hass und Spam lässt jedoch Zweifel aufkommen, ob der Nutzen die Kosten der zeitaufwendigen Kommentarmoderation rechtfertigt. Als Konsequenz daraus haben viele Plattformen ihre Kommentarspalten eingeschränkt oder sogar ganz abgeschaltet. In dieser Arbeit stellen wir Deep-Learning-Verfahren zur Klassifizierung, Empfehlung und Vorhersage von Kommentaren vor, um respektvolle und anregende Online-Diskussionen zu fördern. Das Hauptaugenmerk liegt dabei auf zwei Arten von Kommentaren: toxische Kommentare, die die Leser veranlassen, eine Diskussion zu verlassen, und anregende Kommentare, die die Leser veranlassen, sich an einer Diskussion zu beteiligen. Im ersten Schritt identifizieren und entfernen wir toxische Kommentare, z.B. Beleidigungen oder Drohungen. Zu diesem Zweck stellen wir einen halbautomatischen Moderationsprozess vor, der auf feingranularen Textklassifikationsmodellen basiert und Moderatoren unterstützt. Unsere Experimente zeigen, dass Datenanreicherung, Transfer- und Ensemble-Lernen das Trainieren robuster Klassifikatoren selbst auf kleinen Datensätzen ermöglichen. Um Vertrauen in die maschinell gelernten Modelle zu schaffen, zeigen wir mit attributionsbasierten Erklärungsmethoden auf, welche Teile der Eingabe für ihre Ausgabe entscheidend sind. Im zweiten Schritt ermutigen und markieren wir anregende Kommentare, z.B. ernsthafte Fragen oder sachliche Aussagen. Wir identifizieren automatisch die anregendsten Kommentare, so dass die Leser nicht durch Tausende von Kommentaren blättern müssen, um sie zu finden. Der Trainingsprozess der Modelle baut auf Upvotes und Kommentarantworten als Maß für die Aktivität der Leser auf. Wir identifizieren außerdem Kommentare, die sich an die Artikelautoren richten oder anderweitig für sie relevant sind, um die Interaktion zwischen Journalisten und ihrer Leserschaft zu unterstützen. Unter Berücksichtigung der Interessen der Leser bieten wir darüber hinaus personalisierte Diskussionsempfehlungen an, die sich an den von ihnen bevorzugten Themen oder häufigen Diskussionspartnern orientieren. In Experimenten mit Kommentardatensätzen von verschiedenen Plattformen übertreffen unsere Modelle mehrere grundlegende Vergleichsverfahren und aktuelle verwandte Arbeiten.

BT - an adversarial review JF - Journal of media psychology N2 - Research into the effects of social media on well-being often distinguishes “active” and “passive” use, with passive use supposedly more harmful to well-being (i.e., the passive use hypothesis). Recently, several studies and reviews have begun to question this hypothesis and its conceptual basis, the active/passive dichotomy. As this dichotomy has become a staple of social media research but evidence challenging its validity is mounting, a comprehensive debate on its pros, cons, and potential future is needed. This adversarial review brings together two voices – one more supportive, and the other more critical – toward the active/passive model. In constructive dialogue, we summarize and contrast our two opposing positions: The first position argues that the active/passive dichotomy is a useful framework because it adequately describes how and why passive use is (more) harmful for well-being. The second position challenges the validity of the dichotomy and the passive use hypothesis specifically. Arguments are presented alongside (a) the empirical basis, (b) conceptualization, and (c) operationalization of active and passive use, with particular focus on the passive use hypothesis. Rather than offering a conciliatory summary of the status quo, the goal of this review is to carve out key points of friction in the literature on the effects of social media through fruitful debate. We summarize our main agreements and unresolved disagreements on the merits and shortcomings of the active/passive dichotomy. In doing so, this review paves the way for researchers to decide whether and how they want to continue applying this lens in their future work.

T1 - Digital activism on social media BT - the role of brand ambassadors and corporate reputation management T2 - Proceedings of the 57th Annual Hawaii International Conference on System Sciences N2 - Social media constitute an important arena for public debates and steady interchange of issues relevant to society. To boost their reputation, commercial organizations also engage in political, social, or environmental debates on social media. To engage in this type of digital activism, organizations increasingly utilize the social media profiles of executive employees and other brand ambassadors. However, the relationship between brand ambassadors’ digital activism and corporate reputation is only vaguely understood. The results of a qualitative inquiry suggest that digital activism via brand ambassadors can be risky (e.g., creating additional surface for firestorms, financial loss) and rewarding (e.g., emitting authenticity, employing ‘megaphones’ for industry change) at the same time. The paper informs both scholarship and practitioners about strategic trade-offs that need to be considered when employing brand ambassadors for digital activism.

The investigation of this case extends the knowledge by providing a rich description of the organizational framing of health communication to combat misinformation in a politically charged environment. Design/methodology/approach The authors collected a Twitter dataset of 77,527 tweets and analyzed a purposeful subsample of 536 tweets that contained information provided by Brazilian public health organizations about COVID-19 vaccination campaigns. The data analysis was carried out quantitatively and qualitatively by combining social media analytics techniques and frame analysis. Findings The analysis showed that Brazilian health organizations used several framing devices that have been identified by previous literature such as hashtags, links, emojis or images. However, the analysis also unearthed hitherto unknown visual framing devices for misinformation prevention and debunking that borrow from internet culture such as “infographics,” “pop culture references” and “internet-native symbolism.” Research limitations/implications First, the identification of framing devices relating to internet culture add to our understanding of the so far little addressed framing of misinformation combat messages. The case of Brazilian health organizations provides a novel perspective to knowledge by offering a notion of internet-native symbols (e.g. humor, memes) and popular culture references for misinformation combat, including misinformation prevention. Second, this study introduces a frontier of political contextualization to misinformation research that does not relate to the partisanship of the spreaders but that relates to the political dilemmas of public organizations with a commitment to provide accurate information to citizens. Practical implications The findings inform decision-makers and public health organizations about framing devices that are tailored to internet-native audiences and can guide strategies to carry out information campaigns in misinformation-laden social media environments. Social implications The findings of this case study expose the often-overlooked cultural peculiarities of framing information campaigns on social media. The report of this study from a country in the Global South helps to contrast several assumptions and strategies that are prevalent in (health) discourses in Western societies and scholarship. Originality/value This study uncovers unconventional and barely addressed framing devices of health organizations operating in Brazil, which provides a novel perspective to the body of research on misinformation. It contributes to existing knowledge about frame analysis and broadens the understanding of frame devices borrowing from internet culture. It is a call for a frontier in misinformation research that deals with internet culture as part of organizational strategies for successful misinformation combat.

Lay Summary Active use of social networking sites (SNSs) has long been assumed to benefit users' well-being. However, this established assumption is increasingly being challenged, with scholars criticizing its lack of empirical support and the imprecise conceptualization of active use. Nevertheless, with great diversity among conducted studies on the hypothesis and a lack of causal evidence, a final verdict on its viability is still pending. To contribute to this ongoing debate, we conducted a week-long experimental investigation with 381 adult Instagram users. Specifically, we tested how posting pictures on Instagram affects different aspects of well-being. The results of this study depicted a positive effect of posting Instagram pictures on users' experienced positive emotions but no effects on other aspects of well-being. 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 on users.

Press CY - Oxford ER - TY - THES A1 - Hannes-Vincent, Krause T1 - Social networking site use and well-being - a nuanced understanding of a complex relationship N2 - Social Networking Sites (SNSs) are ubiquitous and attract an enormous chair of the digital population. Their functionalities allow users to connect and interact with others and weave complex social networks in which social information is continuously disseminated between users. Besides the social value SNSs are generating, they likewise attract companies and allow for new forms of marketing, thereby creating considerable economic value alike. However, as SNSs grew in popularity, so did concerns about the impact of their use on social interactions in general and the well-being of individual users in particular. While existing scientific evidence points to both risk as well as benefits of SNS use, research still lacks a profound understanding of which aspects of SNSs enable an impact on well-being and which psychological processes on the part of the users underly and explain this relationship. Therefore, this thesis is dedicated to an in-depth exploration of the relationship between SNS use and well-being and aims to answer how SNS use can impact well-being. Primarily, it focuses on the unique technological features that characterize SNSs and enable potential well- being alterations and on specific psychological processes on the part of the users, underlying and explaining the relationship. For this purpose, the thesis first introduces the concept of well- being. It continues by presenting SNSs’ unique technological features, divided into specifics of the content disseminated on SNSs and the network structure of SNSs. Further, the thesis introduces three classes of psychological processes assumed most relevant for the relationship between SNSs and well-being: other-focused, self-focused, and contrastive processes.. It is assumed that the course and quality of these common processes change in the SNS context and that a complex interplay between the unique features of SNSs and these processes determines how SNSs may ultimately affect users' well-being - both in positive and negative ways. The dissertation comprises seven research articles, each of which focusses on a particular set of SNS characteristics, their interplay with one or more of the proposed psychological processes, and ultimately the resulting effects on user well-being or its key resilience and risk factors. The seven articles investigate this relationship using different methodological approaches. Three articles are based on either systematic or narrative literature reviews, one applies an empirical cross-sectional research design, and three articles present an experimental investigation. Thematically, two articles revolve around SNS use’s effect on self-esteem. Three articles examine the specific role of the emotion of envy and its potential to establish and perpetuate a well-being-damaging social climate on SNSs. The two last articles of this thesis revolve around the established assumption that active and passive SNS use, as different modalities of SNS use, cause differential effects on users’ well-being due to the involvement of different psychological processes. The results of this thesis illustrate different ways how SNSs can affect users’ well-being. The results suggest that especially contrastive processes play a decisive role in explaining potential well-being risks for SNS users. Their interplay with certain SNS features seems to foster upward social comparisons and feelings of envy, potentially leading to a complex set of deleterious effects on users’ well-being. At the same time, the findings illuminate ways in which SNSs can benefit users and their self-esteem – especially when SNS use promotes self- focused and social-feedback-based other-focused processes. The thesis and their findings illustrate that the relationship between SNSs and well-being is complex. Therefore, a nuanced perspective, taking into consideration both the technological uniqueness of SNSs and the psychological processes they are enabling, is crucial to understand how these technologies affect their users in good and potentially harmful ways. On the one hand, the gathered insights contribute to research, providing novel insights into the complex relationship between SNS use and well-being. On the other hand, the results enable a focused and action-oriented derivation of recommendations for stakeholders such as individual users, policymakers, and platform providers. The findings of this thesis can help them to better combat SNS-related risks and ultimately ensure a healthy and sustainable environment for users - and thus also the economic values of SNSs - in the long term.

It tests how affective cues (emotional valence, intensity and collective self-representation) and cognitive cues (insight, causation, certainty and discrepancy) contribute to public engagement. Design/methodology/approach The authors created a dataset of more than three million tweets during the 2020 United States (US) presidential elections. Affective and cognitive cues were assessed via sentiment analysis. The hypotheses were tested in negative binomial regressions. The authors also scrutinized a subsample of far-famed Twitter users. The final dataset, scraping code, preprocessing and analysis are available in an open repository. Findings The authors found the prominence of both affective and cognitive cues. For the overall sample, negativity bias was registered, and the tweet’s emotionality was negatively related to engagement. In contrast, in the sub-sample of tweets from famous users, emotionally charged content produced higher engagement. The role of sentiment decreases when the number of followers grows and ultimately becomes insignificant for Twitter participants with many followers. Collective self-representation (“we-talk”) is consistently associated with more likes, comments and retweets in the overall sample and subsamples. Originality/value The authors expand the dominating one-sided perspective to social media message processing focused on the peripheral route and hence affective cues. Leaning on the dual process theory, the authors shed light on the effectiveness of both affective (peripheral route) and cognitive (central route) cues on information appeal and dissemination on Twitter during a political event. The popularity of the tweet’s author moderates these relationships.

Leveraging a rich dataset in the context of the 2020 U.S. presidential elections containing more than 3 million tweets, we found the prominence of both cue types. For the overall sample, positivity and sentiment are negatively related to engagement. In contrast, the post-hoc sub-sample analysis of tweets from famous users shows that emotionally charged content is more engaging. The role of sentiment decreases when the number of followers grows and ultimately becomes insignificant for Twitter participants with a vast number of followers. Prosocial orientation (“we-talk”) is consistently associated with more likes, comments, and retweets in the overall sample and sub-samples.

This essay goes beyond those two perspectives by looking at the regimes of engagement, developing in interaction with the material and technological environment, that have given the protests their distinctive style. The first part looks at coordination and representation at protest events and in producing protest symbols such as flags. The second part discusses the role of Telegram and the emergence of local protest groups. Even though the movement did not grow organically out of everyday concerns, there are some signs that it has begun to reassemble local communities from above. Yet there are also indications that politics continues to be seen as distinct from everyday life, making it uncertain that the movement will lead to a deeper transformation of society.
