Item type:Publication, Digital Natives or Digital Immigrants? : The Impact of User Characteristics on Online TrustPrevious research suggests that user characteristics such as web experience and demographics may affect online trust. Drawing on social cognitive theory, we explore the moderating effect of user characteristics on online trust. Based on a survey of German Internet users, we differentiate three groups by age, web experience, and education. We term these groups digital natives, digital immigrants, and naturalized digitals. A multiple-group analysis reveals significant differences in trust formation, particularly in the cues considered in the evaluation of online services. Whereas a large user base inspires confidence in digital natives, naturalized digitals are more geared toward familiar brands and recommendations. Digital immigrants most critically weigh the risks of a transaction against its benefits. We argue that specific user characteristics are associated with distinct cognitive schemata, implying distinct interests and evaluations in online transactions. Online services should differentiate their signaling efforts according to the targeted customer group.Type:journal articleJournal:Journal of Management Information SystemsVolume:31Issue:3Scopus© Citations 108 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Two Paths to Adoption : Cognitive and Affective Drivers of Social Media Adoption in Public AdministrationVarious studies have explored the impact of new media on the interaction of governments and their citizenry (e-government) or the engagement of citizens in questions of governance (e-governance). Social media can make participation in public governance logistically feasible by providing access to a wide range of information as well as online conversations. More and more public administrations strive to employ social media for citizen interaction. Yet, little is known about the necessary preconditions of professional social media use in public administration. In this study, we focus on public administration employees' stance towards social media as one important element in the successful implementation of social media projects. Applying insights from technology acceptance research and based on a quantitative survey among the employees of a German state administration, we explore individual-level antecedents of social media use intentions. We distinguish two routes of adoption - a cognitive and an affective one - and find that the affective route is more pronounced. This points to the hedonic status of social media as an information technology and coincides with information systems previous literature.Type:conference paper - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Organizational Antecedents of Social Media Adoption in Public Administration : Considering the Mediating Role of Entrepreneurial OrientationResearch increasingly explores the opportunities social media provide to public sector organizations. Yet, only few empirical studies have addressed the organizational antecedents of social media adoption in this particular context. Based on innovation diffusion literature, we propose a number of organizational antecedents of social media adoption in public administration. At the same time, we find that - due to high levels of formalization and centralization - formal organizational characteristics may exhibit little variability in the public administration context. We therefore suggest that the explanatory power of the proposed model could be increased by considering an intermediate construct capturing the organization's predisposition to explore new media. From current innovation literature, we derive Entrepreneurial Orientation as a potential mediator of social media adoption. Based on a survey among 2'092 employees of a German state-level administration, we test both an unmediated and a partially mediated model of organizational antecedents of social media adoption. We find that Leadership support, Employee autonomy, Bureaucratization, and Social Influence affect social media adoption. Taking the mediating effect of Entrepreneurial Orientation into consideration increases the explanatory power of the proposed model.Type:conference paper - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Spiral of Silence 2.0 : Impression Management and Political Self-Censorsip on FacebookDo social media strengthen or weaken citizen's political participation? Authors have found that, while lowering the cost of political engagement, social media may also foster the fragmentation of audiences and contribute to an increasingly polarized political discourse. This study applies the "spiral of silence" theory to political discourse among digital natives on the social networking platform Facebook. We hypothesize that users perceiving their online network as politically heterogeneous will be more likely to engage in self-censorship and limit their political self-expression. Previous studies have found that impression management, i.e., communication behaviour geared towards projecting a socially desirable self, increases engagement in online social networks. Accordingly, we hypothesize that users geared towards impression management will be more engaged in online political discourse. We test these hypotheses based on a survey among German Facebook users under the age of 30 and find that network heterogeneity does indeed increase political self-censorship while impression management increases users' willingness to speak out.Type:conference paper - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Political Engagement of Digital Natives on Facebook : The Moderating Role of Impression ManagementThis contribution addresses the moderating role of impression management on the relationship between online and offline political participation. It concentrates on young citizens in Switzerland and Germany aged 18-30. After a discussion of the slacktivism thesis as the theoretical backbone of the paper, we describe the dataset and present the method of analysis. Significant differences in political participation - both online and offline - as well as in impression management between Germany and Switzerland exist. Using linear regression models, we elaborate salient drivers of offline participation. Contradicting the slacktivism thesis, we do not find a weakening effect of different impression management techniques on the relationship between political participation on Facebook and offline participation forms, such as demonstrating. By contrast, certain impression management techniques strengthen the online-offline link, while others do not exert a moderating effect. Overall, young citizens in Germany and Switzerland seem to be able to transfer their political engagement on Facebook to offline settings, even when they reveal high levels of impression management. Political engagement on Facebook is not an isolated act of self-staging that fizzles out in the virtual sphere.Type:conference paper - Some of the metrics are blocked by yourconsent settings
Item type:Publication, An Element of Surprise : The Impact of Serendipity on Online Trust(Academy of Management, 2013-08-11); ; ; The importance of user trust in online business is well-established in theory and practice. At the same time, the Internet is a dynamic space with constantly evolving user experiences based on new technological developments. A current example of such a development is the increasing use of algorithms in search and recommendation systems. Critics claim that these algorithms limit the users' Web experience and their ability to come across new and surprising, even challenging insights ("serendipity"). We propose that these developments have an impact on online trust and explore the effect of serendipity on trust formation as well as the role of privacy and security on serendipitous Web uses. Based on a large-scale representative survey among Swiss Internet users, we analyze a quantitative model of privacy perception, serendipity and trust on the Internet. We find that service providers suffering from a lack of trust need to weigh the benefits of a tightly controlled and efficient user experience against those of a more curious, explorative, trusting and less protective customer behavior.Type:conference paper - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Too Much of a Good Thing? : Technostress and Information Overload Among Young Swiss(ICA International Communication Association, 2013-06-20); ; Technostress and information overload are serious challenges of the Information Age. An alarming number of people exhibit excessive media consumption, while Internet addiction seems to be an increasingly widespread phenomenon (Christakis et al., 2011). Although there is evidence for technostress and information overload in a range of studies (Bawden & Robinson, 2009; Eppler & Mengis, 2004; Shenk, 1997; Wang et al., 2008), little is known about how young people feel about overexposure to technology and new media (Akin, 1998). In order to address this gap, we present findings from a survey addressing the social media usage and perceptions of individuals, collected at the Museum for Communication in Bern, Switzerland. Based on a sample including 1915 children and 6989 adolescents and through a quantitative approach (OLS regressions) we explore the impact of cultural background, age and social status on differences in technostress.Type:conference paper - Some of the metrics are blocked by yourconsent settings
Item type:Publication, PR Practitioner Roles Revisited(2012-09-20); ; The article discusses the findings of a quantitative investigation into the work roles of European communication professionals. In particular, our research investigates whether the manager-technician typology, developed in previous role research, still captures the reality of modern communication work, and whether there are any differences in the European context compared to the United States, where most research on practitioner roles has been done to date. Based on structural equation modeling, we show that several assumptions from this stream of research do not hold up to the scrutiny of modern statistical methods. Instead, we propose a more modest interpretation, first of which roles modern communication practitioners actually enact, and second how these roles relate to job satisfaction, managerial input and gender differences in the field.Type:conference paper - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Digital Natives and Digital Immigrants : Differences in Online Trust Formation(Academy of Management, 2012-08-03); ; ; Online applications support and affect an extensive variety of today's social and business interactions. Trust has been identified as a key prerequisite for the acceptance and adoption of online services or applications. Research has come a long way in exploring antecedents and drivers of online trust. A range of authors have hypothesized that user characteristics, such as web experience and demographics, impact online trust formation. Based upon a survey among German internet users, we differentiate two user groups, "Digital Natives" and "Digital Immigrants", and find significant differences in their trust formation. While "Digital Natives" look for a balance in perceived risk and benefit as well as convincing third party endorsements when choosing an online service, "Digital Immigrants" are more interested in large, well-established providers with a recognizable offline presence.Type:conference paperVolume:Session 767 - Some of the metrics are blocked by yourconsent settings
