The increasing amount of data generated by Location Based Social Networks (LBSN) such as Twitter, Flickr, or Foursquare, is currently drawing the attention of urban planners, as it is a new source of data that contains valuable information about the behavior of the inhabitants of a city. Making this data accessible to the urban planning domain can add value to the decision making processes. However,...
Effective and efficient behavioral interventions are important and of high interest today. Due to shortcomings of related approaches, we introduce MobileCoach (mobile-coach.eu) as novel open source behavioral intervention platform. With its modular architecture, its rule-based engine that monitors behavioral states and triggers state transitions, we assume MobileCoach to lay a fruitful ground for...
The study first claims that learning community of practice play a significant role in the fields of virtual or online learning. But there are few evidences or knowledge so far about how school students behave in the virtual learning environment in terms of learning behaviors and interpersonal interaction. APEC Cyber Academy (ACA) is an international networked learning environment designed specifically...
This paper presents an application model for augmenting TV viewing experience. The augmentation consists of additional media resources, which are linked to the Web according to the user profile and to TV metadata. Instead of asking the user for such data, a distributed software system captures them non-intrusively, processes the user and TV program context, and automatically searches for and delivers...
A tremendous amount of information is being shared everyday on social media sites such as Facebook, Twitter, or Google+. Often times these social media texts include information that are valuable to others, such as activities (e.g., art fairs, jazz festivals, and gatherings), natural disaster occurrences (e.g., tornadoes, earthquakes), or incidents (e.g., traffic jams). However, current search on...
Adaptive selling has been seen to increase sales performance and influence tactics provide means to exercise it. However, adaptive selling has only been studied in single-channel contexts. Multi-channel contexts offer particular opportunities to improve adaptive selling by providing information about customers' information processing styles in one channel that can be fed into another channel. In a...
Natural disasters can have a devastating effect on critical infrastructures, especially in case of cascading effects among multiple infrastructures such as the electric power grid, the communication network, and the road network. While there exist detailed models for individual types of infrastructures such as electric power grids, these do not encompass the various interconnections and interdependencies...
Research on phishing has implicated users' heuristic processing as the reason why they fail to recognize deception cues and fall prey to phishing attacks. Other research on online behavior has found that the attributes of the medium activate heuristics that contribute to feelings of presence and enhance the persuasiveness of presented information. The deception literature has, however, yet to examine...
In course of a breaking news event, such as natural calamity, political uproar etc., a massive crowd sourced data is generated over social media which makes social media platforms an important source of information in such scenarios. The value of the information being propagated via social media is being increasingly realised by the news organisations and the journalists. Better tools and methodologies...
The debates on materiality and sociomateriality, hailing from science studies and organization studies, allow information systems (IS) researchers to evade received distinctions between the social, natural and technical. The literatures that inform this Minitrack contest a purely information-based perspective that posit abstract meanings and immaterial data divorced from situated contexts. Instead...
The following paper presents a quantitative content analysis of blog posts of selected discussions on a EU wide e-participation platform with the goal of showing that emotional writing is an indicator for the frequency of participation in online deliberations. The platform analyzed for this research has been designed to bring young people in contact with stakeholders and politicians in order to discuss...
This research explores ebook use among undergraduate students, drawing from the technology acceptance model (TAM) to examine ebook usage and adoption. Undergraduates enrolled in a large course at a mid-western university in the United States completed surveys at the beginning and the end of the semester. A great amount of variance was found in ebook use. A small number of students made a large number...
When disaster strikes, human lives may depend upon emergency organizations' rapid establishment of Situation Awareness (SAW) to take the appropriate decisions and actions. Recently, systems emerged, enabling humans to act as crowd sensors contributing valuable crisis information via mobile devices through social media channels. This should allow enhancing situational pictures gained through traditional...
This study examines the impact of enterprise social media on the workplace. Drawing on the theory of virtuality and the structure-content framework of social networks, we develop a multi-level research model focused on the extent to which individuals' network structures and the content enabled by enterprise social media influence individuals' task performance in dispersed teams. The results of this...
We report on a study exploring how Twitter user attributes and the characteristics of the images they share online influence the diffusion of those images. Two-hundred and ninety unique images were collected from Twitter in October 2013 associated with the gun control hash tag [guncontrol]. A coding protocol was developed and images classified based on frame (attribute, goal, or risk), appeal (e.g...
Virtual teams play an increasingly important role in the modern economy, and many organizations struggle to overcome the weaknesses inherent in technology-mediated work. Identity communication has been shown to greatly improve individual- and group-level outcomes in offline settings, but these benefits have not been investigated in the context of virtual teams, where mediated interaction can reduce...
Most practitioners and researchers recognize that knowledge flows are extremely important, especially in the current age where organizations have to learn and innovate continually in order to remain competitive. Given that knowledge is distributed unevenly through the enterprise, rapid and reliable knowledge flows are essential for organizations' sustainable competitive advantage.Knowledge flows...
This study examines the influences of knowledge-sharing activities and tertius iungens orientation on job performance within social media environments. Through empirical analysis, it finds that knowledge self-efficacy, social interaction ties, and the norm of reciprocity positively influence knowledge-sharing activities in social media environments, and that social interaction ties and the norm of...
Extant literature finds that twitter trends can capture electoral sentiment. However, empirical evidences are ambiguous in nature. Thus, this study uses the context of 2014 Indian General Election to test the predictive power of Twitter in a large and politically diversified country. We have analyzed roughly 0.4 million tweets during the period March 15, 2014 to May 12, 2014. We observe that tweet...
