Despite the role of digital technologies in increasing the popularity of K-pop, little is known about how K-pop entertainment companies digitally transform their business models and the driving forces that shape this transformation. In this study, we present an in-depth case study of a pioneering K-pop entertainment company, SM Entertainment, whose founder's charismatic leadership and organizational capabilities contribute to the digital transformation of its business model through market-pioneering strategies and strategic learning derived from continuous interactions with changing business environments. This transition to the digital business model ultimately leads to sustainable competitive advantages in the marketplace. The important theoretical and practical implications of the findings are discussed. [ABSTRACT FROM AUTHOR]

Blockchain, an emerging paradigm of secure and shareable computing, is a systematic integration of 1) chain structure for data verification and storage, 2) distributed consensus algorithms for generating and updating data, 3) cryptographic techniques for guaranteeing data transmission and access security, and 4) automated smart contracts for data programming and operations. However, the progress and promotion of Blockchain have been seriously impeded by various security issues in blockchain-based applications. Furthermore, previous research on blockchain security has been mostly technical, overlooking considerable business, organizational, and operational issues. To address this research gap from the perspective of information systems, we review blockchain security research in three levels, namely, the process level, the data level, and the infrastructure level, which we refer to as the PDI model of blockchain security. In this survey, we examine the state of blockchain security in the literature. Based on the insights obtained from this initial analysis, we then suggest future directions of research in blockchain security, shedding light on urgent business and industrial concerns in related computing disciplines.

Bicycle-metro integration is theoretically considered to be an effective solution for improving public transportation efficiency of "last mile" between home and metro station in cities. However, this proposition has not been fully proved in practice. In recent years, the emerging dockless bike-sharing system makes it possible to examine the spatial integration between flexible bicycle traffic and rail transit. This study mapped the bicycle traffic on an equal population cartogram of Shanghai to distinguish overall patterns within the center of Shanghai. The research result indicates the sharing bike usage frequency from metro station to outlying area is gradual declining, which demonstrates that bicycle-metro integration has already become the basic model for daily transport in Shanghai.

Introduction:In online medical-consulting platforms, physicians answer medical questions and share health care knowledge with patients, which will bring them both economic returns and social returns. Little research has studied the free online medical-consulting services (FOMCS) and their influences on the performance of patients. Methods:An OLS specification-regression model with robust standard errors clustered at the physician level based on panel data in physician-month level, including 48,406 physicians in 4,452 hospitals in 139 months (August 2006–December 2017) from the largest online health care platform in China. Results:We find that FOMCS positively affects the performance of a physician. Specifically, we found that the 1% increase of FOMCS would help physicians receive an additional 3.1% paid consulting services and an 11.4% increase in income. In addition, this effect is enhanced for physicians due to a high pricing strategy and weakened for physicians with high platform-usage experience and professional titles. Conclusion:We provide evidence on the effect of FOMCS of physicians on their performance and explore this heterogeneous effect in three kinds of mechanisms: pricing of online medical-consulting services, usage experience of online health care platform, and the professional title of a physician. FOMCS can help quality physicians show their skilled abilities to potential patients to attract their business, make up for the lack of usage experience in online health care platforms, and provide an alternative way to build physicians' online reputations. Our results have implications for existing health management and e-health literature. [ABSTRACT FROM AUTHOR]
