Cyber Risk Exposure Through Supply Chain Information Network: An Application Of Social Network Analysis, Long Thai Bui

Information Systems & Operations Management Theses

In this paper, I study the impact of supply chain information networks on cyber risk exposure. I document that firms that are more central in the supply chain information network have higher cyber risk exposure. The rapid advancement of information and communication technology (ICT) has led to increased interconnectedness within global supply chain networks. While this enhances efficiency and profitability, it also exposes these entities to systematic and contagious risks, as cyber criminals exploit the connectedness to infiltrate multiple firms simultaneously.

Affective Commitment, Mentoring, And Anticipated Turnover Among Millennials, Keiasha Hypolite

Dissertations

ABSTRACT

Millennials comprise the largest group of individuals in the workforce, yet organizations struggle to keep millennials engaged in the workplace.

Simulation Modeling For Robust And Just Public Policy Decision-Making, Jack Mitcham

Graduate Doctoral Dissertations

Public policy decision-making is challenging for several reasons. First, the outcomes of pulling a public policy lever are often deeply uncertain because of the complexity of the social and physical systems involved. Second, even if outcomes can be predicted, there are multiple points of view to consider, and the same outcome can be viewed anywhere from very positively to very negatively by different stakeholders. Because of this, public policy decisions should be both robust and just. Robustness helps with the uncertainty in outcomes and justice helps with differences in worldview. In this dissertation, I employ system dynamics and agent-based simulation …

Empowering Older Adults With Their Information Privacy Management, Reza Ghaiumy Anaraky

All Dissertations

Literature depicts a deficit-based narrative around older adults and their technology use, suggesting that older adults are not able to keep up with their younger counterparts in adopting new technologies. In this dissertation, I argue that this view is not necessarily accurate or productive. Instead, I argue that the deficit is in the technology design, which is not inclusive and often caters to the needs of younger adults.

I study older and younger adults' privacy decision-making as a showcase. To study the privacy decision-making process with more granularity, I used a dual-route approach (decision heuristics and privacy calculus) to disentangle …
