EXPLAINING THE ROLE OF SERVICE-ORIENTED ARCHITECTURE FOR CYBER-PHYSICAL SYSTEMS BY ESTABLISHING LOGICAL LINKS

In the context of the so-called fourth industrial revolution, cyber-physical systems (CPS) build the technological foundation for the increasing digitalisation of our world. Because guidelines to overcome challenges of building such systems (e.g. security concerns, missing know-how, and lack of standards) are scarce, researchers and practitioners alike have begun to analyse the role of the mature paradigm of service-oriented architecture (SOA) in implementing CPS. However, the relationship between SOA and CPS is not entirely understood. To close this gap, we analyse SOA’s role for CPS based on a concept-driven literature review. The analysis of 12 publications that address the interrelation between SOA and CPS yielded four groups of CPS benefits that can be achieved by leveraging SOA. Combining these benefits with architectural layers and SOA’s design principles, we identify logical links that explain the role of SOA for CPS. Future research might concentrate on dominant patterns to scrutinise how a specific benefit can be achieved by leveraging SOA. Designers of CPS can leverage the identified patterns to understand the importance of specific characteristics of SOA to address the unique requirements of their CPS

The New Window to Athletes’ Soul – What Social Media Tells Us About Athletes’ Performances

Professional sports has evolved from a game to an organization that has been codified, strategized, and commercialized. One factor that is shaping the sports industry is the pervasiveness of social media. On the one hand, social media is used as a powerful medium for distributing and getting news, engaging in topical discussions, and empowering brands. On the other hand, social media has become a crucial mouthpiece for athletes to interact with peers, share opinions, thoughts, and feelings. However, millions of followers, tweets, and likes later, researchers, practitioners, and athletes alike ask whether social media has an impact on an athlete’s performance. We conducted a social media usage and a sentiment analysis of 124,341 Twitter tweets extracted from 31 tennis athletes. We linked these data to 8,095 corresponding match day performances. The results show that high social media usage has a significant negative impact on athletes’ performance

What We Know and What We Do Not Know About Digital Technologies in the Sports Industry

Recent advances in Digital Technologies (DTs) have transformed various aspects of how the sports industry operates and competes. Common applications of DTs on- and off-site the field of play include, for example, analytics solutions to improve players’ performance, pricing predictions for ticket sales, or digital platforms to interact with fans. DTs further facilitate shared digital capabilities, thereby allowing for the integration of new stakeholders and thus giving rise to new digital ecosystems in the sports industry. However, Information Systems’ (IS) research on DTs in the sports industry is still nascent. Hence, the role of DTs for the sports industry is not entirely understood. Therefore, we analyze how DTs shape the sports industry based on a concept-driven literature review. The analysis of 16 publications yields four groups of benefits that can be achieved by the usage of DTs for the stakeholders embedded in the digital ecosystem of the sports industry
