ItemSocial Media, Rumors, and Hurricane Warning Systems in Puerto Rico( 2019-01-08)Disaster warning systems are a form of risk communication that allow national, state, and local actors to prepare for, respond to, and understand disaster risk. The increased use of social media platforms to exchange information around disasters challenges traditional, centralized forms of risk communication. While social media is already used in emergency management to some degree, issues of trust and reliability of information limit the widespread adoption of social media into emergency management practices. This paper offers a case study of the role that social media information plays in Puerto Rico’s hurricane early warning system and highlights the affordances and limitations of decentralized, heterarchical communication forms around disasters for federal, state, and local-level emergency management authorities. The case highlights differences in perception of social media information around disasters by emergency management authorities and by community members both before and after Hurricane Maria in 2017.
ItemUnderstanding the Effect of Social Media Overload on Academic Performance: A Stressor-Strain-Outcome Perspective( 2019-01-08)Social media has deeply penetrated into university students’ daily lives, inducing excessive usage that can result in social media overload. However, only few studies have explored the adverse consequences of social media use from a pedagogical perspective. This paper aims to investigate the effects of overload on students’ academic performance and the underlying mechanism. Based on the stressor-strain-outcome model, we propose that information, communication, and social overloads influence technostress and exhaustion of students, which in turn impair their academic performance. Results from a study of 249 Chinese social media users in universities reveal that all three types of overload enhance technostress, but only information overload significantly affect exhaustion. Both technostress and exhaustion have negative effects on academic performance. This study enriches social media literature by identifying a more comprehensive classification of social media-related overload among university students and investigating the exact mechanism of excessive social media use in educational environment.
ItemThe Role of Social CRM in Social Information Systems: Findings from Four Case Studies( 2019-01-08)Social Information Systems (SIS) are larger systems of open and voluntary collaboration between involved parties and based on Social Media. Recent research about SIS describes characteristics, constituting elements and research streams. However, detailed analysis about the effects and system design of SIS are still limited. This paper investigates the concept of SIS from the perspective of Customer Relationship Management (CRM). It illustrates similarities and differences between SIS and Social CRM implementations by drawing on existing research and the examination of four cases studies. The findings show benefits and requirements for the adoption of SIS in the field of CRM. On one hand, SIS provide new means for CRM by fostering the creation and nurturing of relationships between business and the market. On the other hand, for realizing these opportunities companies need to further integrate Social Media, CRM and Social CRM from an inside-out and outside-in perspective.
