These vulnerabilities trigger alarm among app developers who fight for their user base: While they are happy to act on users’ information collected via so...

As Facebook has become an integral part of a daily routine for many, the impact of its participation on users’ lives is of growing interest. Nonetheless, extant research does not offer a clear answer on the directionality of the link between Facebook use and markers of subjective well-being. These issues are particularly critical for the vulnerable...

Recognizing the potentially ruinous effect of negative reviews on the reputation of the hosts as well as a subjective nature of the travel experience judgements, peer-to-peer accommodation sharing platforms, like Airbnb, have readily embraced the “response” option, empowering hosts with the voice to challenge, deny or at least apologize for the sub...

The wealth of social information presented on Facebook is astounding. While these affordances allow users to keep up-to-date, they also produce a basis for social comparison and envy on an unprecedented scale. Even though envy may endanger users' life satisfaction and lead to platform avoidance, no study exists uncovering this dynamics. To close th...

Widespread on social networking sites (SNSs), envy has been linked to an array of detrimental outcomes for users’ well-being. While envy has been considered a status-related emotion and is likely to be experienced in response to perceiving another’s higher status, there is a lack of research exploring how status perceptions influence the emergence...

Online businesses are increasingly relying on targeted advertisements as a revenue stream, which might lead to privacy concerns and hinder product adoption. Therefore, it is crucial for online companies to understand which types of targeted advertisements consumers will accept. In recent years, users have been increasingly targeted by political adv...

Visual Social Networking Sites (SNSs) enable users to present themselves favorably to gain likes and the attention of others. Especially, Instagram is known for its focus on beauty, fitness, fashion, and dietary topics. Although a large body of research reports negative weight-related outcomes of SNS usage (e.g., body dissatisfaction, body image co...

In late 2019 about a dozen BISE chairs from the German-speaking community met around ICIS to discuss the ethical challenges arising from the current construction, deployment, and marketing of Information Systems (IS). It turned out that many were and are concerned about the negative implications of IS while at the same time being convinced that dig...

In this proposal, we set out to investigate the role of the technolog...

The rapid emergence of online targeted political advertising has raised concerns over data privacy and what the government’s response should be. This paper tested and confirmed the hypothesis that public attitudes toward stricter regulation of online targeted political advertising are partially motivated by partisan self-interest. We conducted an e...

Internet users commonly agree that it is important for them to protect their personal data. 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...

Data sharing requires researchers to publish their (primary) data and any supporting research materials. With increased attention on reproducibility and more transparent research requiring sharing of data, the issues surrounding data sharing are moving beyond whether data sharing is beneficial, to what kind of research data should be shared and how...

Inequality in the distribution of economic wealth within populations has been rising steadily over the past century, having reached unprecedented highs in many Western societies. However, this development is not reflected in people's perceptions of wealth inequality, as the public tends to underestimate it. Research suggests that inequality estimat...

Mobile devices have become an integral part of everyday life due to their portability. As literature shows, technology use is not only beneficial but also has dark sides, such as addiction. Parents face the need to balance perceived benefits and risks of children’s exposure to mobile technologies. However, no study has uncovered what kind of benefi...

So far research in the area of social networking sites (SNS) has drawn surprisingly little attention to users' conspicuous consumption (CC), even though the constant rise of younger people's debts seems to go hand in hand with the rise of SNS. To fill this research gap, we conducted two studies based on social comparison and normative influence the...

Inspired by increasing IS research on refugees’ ICT use, this study contributes to a better understanding of which smartphone applications (apps) are common among refugees in Germany compared to immigrants and Germans. In relying on the heuristic that most frequently used apps are present on the home screen, we designed a descriptive study to gain...

Previous research offers equivocal results regarding the effect of social networking site use on individuals’ self-esteem. We conduct a systematic literature review to examine the existing literature and develop a theoretical framework in order to classify the results. The framework proposes that self-esteem is affected by three distinct processes...

The recent phenomenon that has come to be known as the European refugee crisis is in reality a global problem. Accordingly, issues regarding refugee integration have become a central topic of debate worldwide. In this paper, we try to understand how refugees use information and communication technology (ICT) in different regions of the world to und...

Reliance on targeted political ads has skyrocketed in recent years, leading to negative reactions in media and society. Nonetheless, only few studies investigate user privacy concerns and their role in user acceptance decisions in the context of online political targeting. To fill this gap, in this study we explore the magnitude of privacy concerns...

Social networking sites (SNSs) are central to social interaction and information sharing in the digital age. However, consuming social information on SNSs invites social upward comparisons with highly socially desirable profile representations, which easily elicits envy in users and leads to unfavorable behaviors on SNSs. This in turn can erode the...

Given the rising popularity of social networking sites (SNSs), the influence of these platforms on the subjective well-being (SWB) of their users is an emerging topic in information systems research. Building on the norm of reciprocity and the social functional approach to positive emotions, we posit that targeted reciprocity-evoking forms of SNS a...

Member countries of the EU-28 received a record number of submitted asylum applications, reaching 1.20 million based on Eurostat (2016) database. Being the country with the highest number of asylum seekers in Europe (BAMF, 2015; BBC, 2016), Germany is t...

Despite good intentions of users who share updates on SNSs, there is mounting evidence that recipients of SNS content frequently perceive shared information as inappropriate, annoying, envy-inducing, and excessive. To examine this apparent gap, we draw on the communication theory and the perceptual congruence model to analyze perceptual differences...

Following recent call for papers, our paper contributes to the agenda of inclusive development as it showcases how technology can be used to foster the integration of those in need.
