Dr. Kwasi Amoako-Gyampah
Kwasi Amoako-Gyampah’s research interests are in supply chain operations strategy and technology implementation. Early research in technology implementation focused on policies in the manufacturing environment that led to effective use of technology. Specifically he looked at tooling strategies and maintenance policies for flexible manufacturing systems. Continuing in this stream he began to look at the role of user involvement in technology implementation and in more recent times has done work on how technology initiative announcements impact stock market returns of firms. His recent work on supply chain operations strategy has focused on operations strategies in least developed economies and how these strategies might differ between small and large firms, and between family and non-family firms.
I examine behavioral and managerial issues in using information technologies in organizations and societies. One of my focus areas is global issues of information technology management and use. Another area I have started looking into is the implementation of IT in the healthcare arena. Currently I am spearheading the “World IT” project team, comprised of several dozen researchers from all over the world. This multi-year project will examine critical IT-related organizational, technological, and individual issues in over forty countries. A sound understanding of these issues from a geocentric perspective would have direct benefits and implications at the firm, national, and international levels. In the healthcare domain, I am investigating challenges and solutions to the successful implementation of IT solutions in this lagging industry.
Dr. Aaron Ratcliffe
Aaron Ratcliffe’s research interests are in healthcare operations management, service operations, humanitarian operations management, sustainable operations management and retail operations management. His research emphasis on healthcare operations management is motivated by his work with UNC Health Care System, the UNC School of Public Health and the UNC Department of Emergency Medicine. His work on health provider competition examines situations under which fixed-price competition over quality and wait-time may lead to lower quality effort at lower wait time. His work on capacity planner for cancer prevention examines tradeoffs between screening guidelines and appointment delays for screens to determine the optimal screening capacity decisions. For outpatient scheduling, his work derives near-optimal heuristic scheduling policies to help clinics control the costs of high patient no-show rates.
Dr. Ling Xue
Ling Xue’s research interests are in IT governance, the impact of IT on organizational structure and performance, IT risk taking and IT in supply chains. His research on IT governance reveals a curvilinear relationship between IT decision right allocation and environmental uncertainty, i.e. firms tend to centralize IT decision making in either highly certain or highly uncertain environments and decentralize IT decision making in environments with moderate uncertainty. His research on IT business value shows that firms tend to gear their IT strategies toward efficiency improvement in stable environments and toward innovation improvement in unstable environments. His research on IT and organizational scope illustrates that IT interacts with narrowly valuable assets to reduce firm (vertical and horizontal) scope and that IT interacts with broadly valuable assets to increase firm (vertical and horizontal) scope. He is currently studying the relationship between executive compensation and IT risk taking, as well as the alliance-based competition in IT industries.
Xia Zhao’s research interests entail understanding how technological innovations transform firms’ competitive strategies and what design and policy interventions can improve the value of these technologies to firms. Her studies on target advertising have addressed important questions regarding the management of individual-level consumer data. Her research shows that firms engaging in behavioral targeting may gain by sharing their proprietary consumer data with their competitors that are less informed about the consumers. Her work also provides practitioners guidance on designing innovative business models that facilitate firms to exchange consumer data. Her studies on information security provide policies for firms to govern their valuable information assets when information security risks are intricately interdependent. Her work on IT governance explains how the IT decision right allocation and system modularity influence the performance of digital supply chain. She is presently investigating the dynamics of online gray market for luxury fashion goods and the policy implications to brand owners.
