(2019): Media are social actors: Individuals’ social responses to social robots and mobile phones. ProQuest Information & Learning.
Abstract: The Computers are Social Actors (CASA) paradigm was proposed more than two decades ago to understand humans’ interaction with computer technologies. Today, as emerging media technologies including social robots and smartphones become more personal and persuasive, questions of how users respond to them socially, what individual factors leverage the relationship, and what constitutes the social influence of these technologies need to be addressed. As an expansion of the CASA paradigm, the Media are Social Actors (MASA) paradigm was applied in the current dissertation to understand users’ social perception, social attitudes, and social behavior in their interactions with humanoid social robots and smartphones. Two lab experiments with between-subjects factorial design were conducted. A total of 110 participants were asked to interact with a humanoid social robot and a smartphone respectively in a socio-emotional context and a task-oriented context. Four pairs of social cues were compared to understand their influence on users’ anthropomorphism of the technologies. Multivariate analyses and textual analyses were conducted. Results suggested that users developed more trust in the social robot with a human voice than with a synthetic voice. Users also developed more intimacy and more interest in the social robot when the robot was paired with humanlike gestures. However, individual differences such as users’ attitudes toward robots, robot use experiences, and suspension of disbelief affected users’ psychological responses to the social robot. Although users’ responses to the smartphone did not vary based on the language styles and the modalities, factors such as individuals’ intensive smartphone use, mobile use habits, and their source orientation and re-orientation moderated the social influence of the smartphone. The dissertation has theoretical value in expanding the CASA paradigm to social robots and smartphones. It also tests the validity of the propositions of the MASA paradigm. The results can lead to more comprehensive, nuanced, and exciting discoveries of the social implications, ethical implications, and practical guides of using these emerging media technologies in the future.

(2018) : Into the wild: Big data analytics in moral psychology. In: Gray, Kurt James; Graham, Jesse (Hg.): Atlas of moral psychology: What do we evaluate when we evaluate moral character? - Helzer, Erik G.; Critcher, Clayton R.: New York, NY: The Guilford Press, S. 525-536, zuletzt geprüft am 25.04.2018
Abstract: How can we investigate moral values in the real world? We propose that naturally generated linguistic data, such as social media content, can be used to study morality outside of the laboratory. Moral values are culturally variable entities that emerge from dynamic, hierarchical interactions between individual- and group level phenomena. Human-generated unstructured data from sources such as social media offer an unprecedented opportunity to observe these phenomena in a natural habitat, which is an essential vantage point for understanding moral values and their role in moral judgment and behavior. We believe it is vital that researchers supplement traditional methodologies with alternative approaches that have greater ecological and external validity and that are better able to capture the full social–functional range of morality. In this chapter, we argue that a range of computationally intensive methods, drawn predominantly from computer science and computational linguistics , can help researchers do just this. By mining psychologically relevant information from large-scale, human-generated, online data such as blog posts, news articles, tweets, Facebook status updates, and social network structures—collectively referred to as 'big data'—researchers can use these methods to investigate morally relevant phenomena in the real world. These methods enable researchers to investigate large-scale, diachronic moral phenomena such as the diffusion of moral values through populations and the moralization of specific topics. They also offer researchers new opportunities to investigate the relationship between moral values and moral behavior, which is both notoriously difficult to study in the laboratory and deeply important for understanding how morality functions.

(2018): The Perils and Promises of Self-Disclosure on Social Media. In: Information Systems Frontiers 20 (3), S. 425-437. DOI: 10.1007/s10796-017-9806-7
Abstract: In addition to their professional social media accounts, individuals are increasingly using their personal profiles and casual posts to communicate their identities to work colleagues. They do this in order to 'stand out from the crowd' and to signal attributes that are difficult to showcase explicitly in a work setting. Existing studies have tended to treat personal posts viewed in a professional context as a problem, since they can threaten impression management efforts. These accounts focus on the attempts of individuals to separate their life domains on social media. In contrast, we present the narratives of professional IT workers in India who intentionally disrupt the boundaries between personal and professional profiles in order to get noticed by their employers. Drawing on the dramaturgical vocabulary of Goffman (1959) we shed light on how individuals cope with increased levels of self-disclosure on social media. We argue that their self-presentations can be likened to post-modem performances in which the traditional boundaries between actor and audience are intentionally unsettled. These casual posts communicate additional personal traits that are not otherwise included in professional presentations. Since there are no strict boundaries between formal front-stage and relaxed back-stage regions in these types of performance, a liminal mental state is often used, which enables a better assessment of the type of information to present on social media.

(2018): Exploring digital remediation in support of personal reflection. In: International Journal of Human-Computer Studies 110, S. 53-62. DOI: 10.1016/j.ijhcs.2017.10.002
Abstract: Increasingly our digital traces are providing new opportunities for self-reflection. In particular, social media (SM) data can be used to support self-reflection, but to what extent is this affected by the form in which SM data is presented? Here, we present three studies where we work with individuals to transform or remediate their SM data into a physical book, a photographic triptych and a film. We describe the editorial decisions that take place as part of the remediation process and show how the transformations allow users to reflect on their digital identity in new ways. We discuss our findings in terms of the application of Goffman's (1959) self-presentation theories to the SM context, showing that a fluid rather than bounded interpretation of our social media spaces may be appropriate. We argue that remediation can contribute to the understanding of digital self and consider the design implications for new SM systems designed to support self-reflection

(2017): Distinguishing technologies for social interaction: The perceived social affordances of communication channels scale. In: Communication Monographs 84 (3), S. 298-318. DOI: 10.1080/03637751.2017.1332418
DOI: https://doi.org/10.1080/03637751.2017.1332418 Abstract: The concept of affordances in communication technology research has proven to be heuristically provocative, yet perceived affordances are rarely measured. After extracting commonly cited social affordances from the literature, we developed a measure to assess participants’ perceptions of these affordances. The scale was tested across eight communication channels in two studies (face-to-face; texting; phone; email; posts on social networking sites, specifically Facebook; instant messaging; Skype videoconferencing; and mobile app Snapchat). A factor structure was developed in Study 1 and confirmed in Study 2. The resultant Perceived Social Affordances of Communication Channels Scale includes 41 items measuring 10 communicative affordances: accessibility, bandwidth, social presence, privacy, network association, personalization, persistence, editability, conversation control, and anonymity. Potential methodological and theoretical applications are discussed.

(2017): The use and impact of Twitter at medical conferences. Best practices and Twitter etiquette. In: Seminars in Hematology 54 (4), S. 184-188. DOI: 10.1053/j.seminhematol.2017.08.003
DOI: https://doi.org/10.1053/j.seminhematol.2017.08.003 Abstract: The use of social media, and in particular, Twitter, for professional use among healthcare providers is rapidly increasing across the world. One medical subspecialty that is leading the integration of this new platform for communication into daily practice and for information dissemination to the general public is the field of hematology/oncology. A growing amount of research in this area demonstrates that there is increasing interest among physicians to learn not only how to use social media for consumption of educational material, but also how to generate and contribute original content in one’s interest/expert areas. One aspect in which this phenomenon has been highlighted is at the time of maximum new information presentation: at a major medical conference. Hematologists/oncologists are engaging regularly in one of the most common forms of social media, Twitter, during major medical conferences, for purposes of debate, discussion, and real-time evaluation of the data being presented. As interest has grown in this area, this article aims to review the new norms, practices, and impact of using Twitter at the time of medical conferences, and also explores some of the barriers and pitfalls that users are encountering in this emerging field.

(2017): Linguistic Deception of Chinese Cyber Fraudsters. In: 3L The Southeast Asian Journal of English Language Studies 23 (3), S. 108-122. DOI: 10.17576/3L-2017-2303-08
Abstract: Cybercrimes are on the increase in China and 'QQ', an instant messenger platform, is frequently exploited for these crimes. Fraudsters manipulate language to deceive users into revealing their bank accounts or depositing sums in the cheats' accounts. Employing the theoretical framework that includes Speech Act Theory and Politeness Theory, the researchers attempted to identify the strategies used by such fraudsters. The subjects of this study included 50 interlocutors who had already chatted with different online cheats and had a record of their conversations. The data were collected and analysed on the basis of the type of discourse themes displayed. Findings indicated that the chats displayed various themes like Business Invitation, Money Transfer, Account Hacking and Online Shopping. In addition, the three levels of speech acts of locutionary, illocutionary, and perlocutionary were discernible and most fraudsters did not bother to address face threatening acts. In comparison to hoax email writers, the fraudsters in instant communication regularly came across as more aggressive and imperative, but then softened their diction if victims were not interested to chat with them in real time. The implications of this study lie in the possibility of developing a model for fraudster or cheat discourse structure, thus alerting QQ users in particular of such crimes. Other online instant messenger users will also benefit from this study. Better informed of how cheats manipulate language to present untruth as truth and be alerted of the modus operandi involved in online deception, victims can be saved and the crime curbed. The issue of the victim's vulnerability and the reasons behind it certainly deserve further linguistic and metalinguistic scrutiny.

(2017): Detecting deceptive engagement in social media by temporal pattern analysis of user behaviors. A survey. In: Wiley Interdisciplinary Reviews: Data Mining and Knowledge Discovery 7 (5). DOI: 10.1002/widm.1210
Abstract: Deceptive engagement in social media, such as spamming, commenting, or rating with automatic scripts, spreading fabricated facts, seriously affects users' trust on online services. Given the large volumes of information generated by users, effectively spotting users involved such deceptive engagement has become a challenging problem. Recent research has shown that techniques for analyzing temporal behavioral patterns are critical to address such problem. In this study, we survey recent advances in these techniques. We first summarize three approaches to model temporal information. Then, by using representative application examples, we discuss recent approaches with respect to their applications to real-world large-scale social media. With a focus on the temporal perspective, we then discuss advantages and challenges of each approach. (C) 2017 John Wiley & Sons, Ltd

(2016): Democracy online. Civility, politeness, and the democratic potential of online political discussion groups. In: New Media & Society 6 (2), S. 259-283. DOI: 10.1177/1461444804041444
Abstract: The proponents of cyberspace promise that online discourse will increase political participation and pave the road for a democratic utopia. This article explores the potential for civil discourse in cyberspace by examining the level of civility in 287 discussion threads in political newsgroups. While scholars often use civility and politeness interchangeably, this study argues that this conflation ignores the democratic merit of robust and heated discussion. Therefore, civility was defined in a broader sense, by identifying as civil behaviors that enhance democratic conversation. In support of this distinction, the study results revealed that most messages posted on political newsgroups were civil, and further suggested that because the absence of face-to-face communication fostered more heated discussion, cyberspace might actually promote Lyotard's vision of democratic emancipation through disagreement and anarchy (Lyotard, 1984). Thus, this study supported the internet's potential to revive the public sphere, provided that greater diversity and volume of discussion is present.

(2016): when I need/want to. Normativity, identity, and form in user construals of ‘talk-like’ tweeting. In: Discourse, Context & Media 14, S. 54-62. DOI: 10.1016/j.dcm.2016.09.003
Abstract: The focus of this study is on how Twitter users construe talk-like tweeting in metalinguistic utterances. In a material of tweets containing or responding to explicit comparisons of tweeting to talking (N=520), a broad range of construals are identified, showing Twitter users associating talk-likeness with, e.g., notions of the textual representation of voice, of grammatical (in-)correctness, of accurately reflecting one's 'real-life' identity, and of regional or social variation in language use. These associations frequently serve normative functions, enforcing or contesting linguistic and discursive norms in both serious and playful ways. The findings offer a novel perspective on the oft-debated orality of computer-mediated discourse, providing a window on how a process of enregisterment (Agha, 2007) is instantiated and how language norms are actively negotiated by participants in everyday online language use on Twitter.

(2015): Political science. Exposure to ideologically diverse news and opinion on Facebook. In: Science (New York, N.Y.) 348 (6239), S. 1130-1132. DOI: 10.1126/science.aaa1160
DOI: http://www.ncbi.nlm.nih.gov/pubmed/25953820 Abstract: Exposure to news, opinion, and civic information increasingly occurs through social media. How do these online networks influence exposure to perspectives that cut across ideological lines? Using deidentified data, we examined how 10.1 million U.S. Facebook users interact with socially shared news. We directly measured ideological homophily in friend networks and examined the extent to which heterogeneous friends could potentially expose individuals to cross-cutting content. We then quantified the extent to which individuals encounter comparatively more or less diverse content while interacting via Facebook's algorithmically ranked News Feed and further studied users' choices to click through to ideologically discordant content. Compared with algorithmic ranking, individuals' choices played a stronger role in limiting exposure to cross-cutting content.

(2015): Perpetuating online sexism offline. Anonymity, interactivity, and the effects of sexist hashtags on social media. In: Computers in Human Behavior 52, S. 436-442. DOI: 10.1016/j.chb.2015.06.024
DOI: https://doi.org/10.1016/j.chb.2015.06.024 Abstract: Sexism and sexual harassment are not uncommon in online environments such as social networking sites, forums, and video games. This experiment investigated whether users’ anonymity and level of interactivity with sexist content on social media influenced sexist attitudes and offline behavior. Participants (N = 172) used a Twitter account that was anonymous or had personally identifying details. They were asked to share (i.e., retweet) or write posts incorporating a sexist hashtag. After exposure, participants completed two purportedly unrelated tasks, a survey and a job hiring simulation in which they evaluated male and female candidates’ resumés. Anonymous participants reported greater hostile sexism after tweeting than nonanonymous participants. Participants who composed sexist tweets reported greater hostile sexism and ranked female job candidates as less competent than those who retweeted, although this did not significantly affect their likelihood to hire. zitiert von 28

(2015): Digital design and social interfaces. A study of the Twitter interface. In: REVISTA MEDIACAO 17 (21)
Abstract: The objective of this study was to identify and characterize a specific type of digital interface, i.e., social interfaces. To this end, we started from a theoretical framework that seeks to place social interfaces as a digital interface subtype, characterized by its proximity to concepts like computer-mediated interaction, Internet-based social networking sites, and social networking sites. After defining and identifying the types and elements of social interfaces, a qualitative exploratory study of transformations over the Twitter social networking site over time was carried out. The results show changes over time in the tool's interface, seeking to meet the different needs of the user's social interaction when using Twitter.

(2013): Does It Matter Where You Read the News Story?. Interaction of Incivility and News Frames in the Political Blogosphere. In: Communication Research 41 (6), S. 809-827. DOI: 10.1177/0093650212449353
Abstract: The political blogosphere is replete with uncivil discussions and is apt to examine the influence of incivility on news frames. The present study brings in literature from incivility and framing effects and uses two experiments to examine the influence of incivility on news frames for democratic outcomes such as willingness to participate, online participation, openmindedness, and attitude certainty. Primary findings indicate the detrimental effects of incivility causing less openmindedness and more attitude certainty. At the same time, incivility causes more willingness to participate and online participation. More importantly, the findings demonstrate how incivility interacts with news frames. Implications for news framing effects in the social media landscape are discussed.

(2010): “You Have No Idea What You are Talking About!. ” From e-disagreement to e-impoliteness in two online fora. In: Journal of Politeness Research. Language, Behaviour, Culture 6 (1). DOI: 10.1515/jplr.2010.004
Abstract: This paper reports on an ongoing project in the area of intentional impoliteness as perceived by the participants and as marked in discourse in the asynchronous Computer Mediated Communication (CMC) context. We focus on occurrences of “impolite talk” and examine the context bound nature of communicative strategies adopted by the interactants in order to deliberately do impoliteness. We also analyze how impoliteness is lexicalized in relation to the inherent characteristics of the CMC context. Specifically, this paper draws on a sample of data from two Communities of Practice (CofP): Greek students and professional academics. 200 posts were collected from interactions where dispute occurred. Special attention is paid to the use of spelling and punctuation and one interactional discourse particle, namely [re] (untranslatable), in unmitigated confrontational disagreement that breaches the norms of unmarked behaviour in the two CofPs. Our preliminary findings show that (im)politeness is firmly embedded in the micro (discourse) and macro (social) context. The impoliteness strategies employed by the interactants indicate different judgements of what constitutes marked behaviour and are contingent on factors such as the overall purpose of communication, the co-constructed norms of the forum, the relationship between participants and the dynamic group identities which the interactants call upon in any given situation.

(2008): Internet Users' Information Privacy-Protective Responses. A Taxonomy and a Nomological Model. In: MIS Quarterly 32 (3), S. 503-529. DOI: 10.2307/25148854
Abstract: Although Internet users are expected to respond in various ways to privacy threats from online companies, little attention has been paid so far to the complex nature of how users respond to these threats. This paper has two specific goals in its effort to fill this gap in the literature. The first, so that these outcomes can be systematically investigated, is to develop a taxonomy of information privacy-protective responses (IPPR). This taxonomy consists of six types of behavioral responses-refusal, misrepresentation, removal, negative word-of-mouth, complaining directly to online companies, and complaining indirectly to third-party organizations-that are classified into three categories: information provision, private action, and public action. Our second goal is to develop a nomological model with several salient antecedents-concerns for information privacy, perceived justice, and societal benefits from complaining-of IPPR, and to show how the antecedents differentially affect the six types of IPPR. The nomological model is tested with data collected from 523 Internet users. The results indicate that some discernible patterns emerge in the relationships between the antecedents and the three groups of IPPR. These patterns enable researchers to better understand why a certain type of IPPR is similar to or distinct from other types of IPPR Such an understanding could enable researchers to analyze a variety of behavioral responses to information privacy threats in a fairly systematic manner. Overall, this paper contributes to researchers' theory-building efforts in the area of information privacy by breaking new ground for the study of individuals' responses to information privacy threats.
