The use of IT-enabled crowdsourcing with employees in enterprises has increased substantially in recent years. This phenomenon, which we refer to as “internal crowdsourcing”, is distinct both from external crowdsourcing with end users and from hierarchy-based work with employees. A literature stream has emerged that corresponds with the increased r...

Social media platforms, especially Twitter, have become a ubiquitous element in political campaigns. Although politicians, journalists, and the public increasingly take to the service, we know little about the determinants and dynamics of political talk on Twitter. We examine Twitter’s issue agenda based on popular hashtags used in messages referri...

Contemporary media systems are in transition. The constellation of organizations, groups, and individuals contributing information to national and international news flows has changed as a result of the digital transformation. The "hybrid media system" has proven to be one of the most instructive concepts addressing this change. Its focus on the mu...

AI-based technologies have changed the nature of the symbiosis between humans and AI, and so strategic management of human-AI interaction in organizations requires deeper ethical considerations. Aligning AI with human values requires a systematic understanding of the ethical management of human-AI interaction. We conduct a theoretical review, from...

Research on the role of social media in crisis management has led to a deeper understanding of their affordances. This research, however, is fragmented, with a primary focus on crisis response. We lack a clear conceptualization of the affordances that social media offer by learning from them to prepare strategically for crises. Based on a systemati...

With nudges, conversational agents (CAs) can be used to recommend environmentally sustainable products to individuals shopping online. CAs can thus influence individual purchase behaviors and have the potential to promote green decision-making. There is a lack of qualitative insights into how CA nudges might influence the purchase decisions of indi...

How individuals understand Artificial Intelligence (AI) affects whether they can interact with AI assistants appropriately. To foster the appropriate use of AI assistants, individuals require realistic perceptions of what AI can or cannot do. However, perceptions (which we refer to as AI narratives) depend on individuals' AI literacy and their emot...

Organizations must align their strategies and renew their capabilities to create business value from advances in artificial intelligence (AI). Ambidextrous leadership is relevant here, as leaders must decide how, when, and where to deploy AI, balancing between its use for increased efficiency (exploitation) and for innovation (exploration). Making...

Analyzing symbols shared within online communities (OCs) is essential to better understand communities’ expressed cultures. To evaluate how OCs differ in their expressed culture and analyze the effects of community rules (CR) and moderation policies (MP), we examined meme sharing of subreddit and interaction communities on Reddit. To detect memes s...

Individuals increasingly seek algorithmic advice to optimize their decision making. This study aims to investigate the effects of receiving algorithmic advice on individuals' attribution of responsibility for their achievements. The study is based on an experiment with a 2 x 5 design of two dimensions: achievement (success vs. failure) and advice (...

Portrayals of violence are common in contemporary media reporting; they attract public attention and influence the reader's opinion. In the particular context of a social movement such as Black Lives Matter (BLM), the portrayal of violence in news coverage attracts public attention and can affect the movement's development, support, and public perc...

Artificial Intelligence (AI) has the potential to change the future of work by improving employee task performance. Unlocking this potential requires that organizations prioritize developing employee AI competencies. Our understanding of AI competencies required to engage with AI-based systems effectively, however, is limited. The concept of AI lit...

The evolution theory of ageing predicts that reproduction comes with long-term costs of survival. However, empirical studies in human species report mixed findings of the relationship between fertility and longevity, which varies by populations, time periods, and individual characteristics. One explanation underscores that changes in survival condi...

The international rise of populism has been attributed, in part, to digital media. These media allow the backers of populists to share and distribute information independent of traditional media organizations or elites and offer communication spaces in which they can support each other and strengthen communal ties irrespective of their societal sta...

The highly integrated design of the electrified powertrain creates new challenges in the holistic testing of high-quality standards. Particularly test technicians face the challenge, that lots of machine-sensor data is recorded during these tests that needs to be analyzed. We present VIMA, a VA system that processes high dimensional machine-sensor...

Social Information Systems (SocIS) enable many people to interact digitally and collaboratively create and share digital content. Nevertheless, the large and heterogenous SocIS communities make it challenging to ensure information quality (IQ) because members' interpretation and evaluation of content might be very different. As a remedy, many platf...

Online platforms, such as Facebook, Twitter, and Reddit, provide users with a rich set of features for sharing and consuming political information, expressing political opinions, and exchanging potentially contrary political views. In such activities, two types of communication spaces naturally emerge: those dominated by exchanges between political...

After Jeff Bezos, the founder and CEO of Amazon, acquired The Washington Post in late 2013, the newspaper’s neutrality and independence from Bezos’ agenda has been in question. This paper takes a first step at exploring whether the neutrality of The Washington Post has changed after the acquisition in 2013. By analyzing the content of newspaper art...

The paper describes and evaluates an explorative approach to quantify the relationship between trainable animals and their owners. Data on human-animal interaction has been collected by using Pebble smartwatches and by observing different kinds of animal training sessions. Tracking movement of horses and dogs with the Pebble Watch was successful wi...

After Jeff Bezos, the founder and CEO of Amazon, acquired the Washington Post in late 2013, many people have accused him of influencing the newspaper’s articles in favor of Amazon. Even though those accusations have not been proven, there is an overall consensus among researchers and scientists, that mass media and newspapers in general control the...

Researchers and practitioners alike recognise the importance of emergency management (EM) in limiting the adverse impacts of crisis events, as well as the promise of social media to support these efforts. Decision making, which is crucial to ensure the effective management of immediate, emerging, and sustained crises, is one facet of EM potentially...

Modeling, analysis, control, and management of complex social networks represent an important area of interdisciplinary research in an advanced digitalized world. In the last decade social networks have produced significant online applications which are running on top of a modern Internet infrastructure and have been identified as major driver of t...

In the wake of an increasing interest in the communication networks of emergency responders, radio communication systems have been recognized as an important source of digital trace data. In this paper, we explore how radio data can be used as part of social network analysis (SNA). In particular, we investigate how social networks can be modeled an...

As part of an ongoing research project, we have designed and implemented a mobile crisis response system (MCRS), which creates a nexus between relief organizations and unaffiliated disaster volunteers. We developed the MCRS using a design science approach and address information management, coordination, and motivation challenges in the context of...

Data and information quality (DIQ) have been defined traditionally in an organizational context and with respect to traditional information systems (IS). Numerous frameworks have been developed to operationalize traditional DIQ accordingly. However, over the last decade, social information systems (SocIS) such as social media have emerged that enab...

Die Theorien und Methoden der Netzwerkforschung werden in vielen Forschungsbereichen und wissenschaftlichen Disziplinen angewendet.

Dennoch bildet ihre Vielfalt an Konzepten, Ideen und theoretischen Zugangsweisen einen erfreulich integrier...

This thesis investigates the role of technology in the collective dynamics of digitally enabled social networks. Based on a review of the historical foundation of research on crowds, collective behaviour, and collective dynamics in the social sciences and in research on complex systems, it develops a conceptualisation of collective dynamics in the...

The increasing number of man-made crises presents relief organizations with serious challenges. For one, paid relief workers are increasingly scarce, making disaster volunteers essential components of official endeavors. But there are several issues concerning communication with as well as coordination and organization of disaster volunteers that h...

The widespread availability and use of social media has drastically altered disaster response in the last few years. Although a considerable amount of empirical research addresses social phenomena enabled by social media in response to disasters, the field still lacks a clear-cut knowledge base. We conduct a systematic literature review to illustra...

Communication between and within crisis response organizations (i.e., fire and rescue services, medical assistance, government agencies, public organizations, police) and the public (i.e., victims, volunteers, people affected by the attacks) is essential for coping with natural or man-made crises such as Hurricane Katrina or the terror attacks of 9...

In this article, we examine the relationship between metrics documenting politics-related Twitter activity with election results and trends in opinion polls. Various studies have proposed the possibility of inferring public opinion based on digital trace data collected on Twitter and even the possibility to predict election results based on aggrega...

Data and information quality (DIQ) have been defined traditionally in an organizational context and with respect to traditional information systems (IS) as, for example, “fitness for use” of data or “intrinsic” DIQ. Numerous frameworks have been developed that operationalize traditional DIQ accordingly. However, over the last decade, social IS such...

Organizations increasingly rely on group-based organizational structures to manage uncertain environments. However, at the group level there is still a limited understanding of how boundary-spanning activities should be managed to increase group performance. In this paper, we propose "out-group-tie centralization" as a concept that refers to the va...

The crowdfunding phenomenon has garnered a considerable amount of attention in recent years. Several online crowdfunding platforms have risen to prominence; they can be characterized as two-sided marketplaces. Recent research reveals initial insights into the dynamics and characteristics of crowdfunding networks arising from such marketplaces. This...

The goal of this paper is to study the psychographic and demographic attributes and the interests of lifestyle of health and sustainability (LOHAS) consumers. Based on a dataset of 3,813 user profiles from the largest LOHAS community site on Facebook, we applied association rule mining and logistic regression to achieve this goal. We focused our wo...

There has been a considerable amount of recent research on the link prediction problem, that is, the problem of accurately predicting edges that will be established between actors in a social network in a future period. With the cooperation of the provider of a German social network site (SNS), we aim to contribute to this line of research by analy...

Just as most people are not WEIRD, the assumption of industry uniformity may not be true in all cases. Several reviews showed that IS research does not take industry seriously enough. Neglecting industry context can have a severe effect on research results by underspecifying theory or by leading to general explanations that do not hold in other con...
