The importance of project governance in curbing opportunistic behavior (OB) has been clearly established the literature. Although contract and trust are considered critical factors that explain governance, there is a lack understanding regarding their interplay at various stages development. current study takes dynamic perspective breaks down into completeness (CC) enforcement (CE), while diffe...

In this work, we consider a client relay wireless system, where users cooperate to send uplink data packets. We focus on the simplest, but realistic network topology and derive the primary performance metrics, including throughput, mean packet delay, and energy efficiency. Importantly, our model enables opportunistic reception and transmission of relay packets thus allowing for many useful insi...

Economists are quick to assume opportunistic behavior in almost every walk of life other than our own. Our empirical methods are based on assumptions of human behavior that would not pass muster in any of our models. The solution to this problem is not to expect a mass renunciation of data mining, selective data cleaning or opportunistic methodology selection, but rather to follow Leamer’s lead...

Given the global challenges of security, both in physical and cyber worlds, security agencies must optimize the use of their limited resources. To that end, many security agencies have begun to use "security game" algorithms, which optimally plan defender allocations, using models of adversary behavior that have originated in behavioral game theory. To advance our understanding of adversary beh...
