This paper proposes two novel techniques for including contingencies in OPF-based electricity market computations and for the estimation of a “System-wide” Available Transfer Capability (SATC). The OPF problem formulation includes voltage stability constraints and a loading parameter in order to ensure a proper stability margin for the market solution. Two methods are proposed: The first techni...

F on individual outsourcing decisions in IT research has often yielded contradictory findings and recommendations. To address these contradictions, we investigate a holistic, configurational approach with the prevailing universalistic or contingency perspectives in exploring the effects of IT outsourcing strategies on outsourcing success. Based on residual rights theory, we begin by identifying...

From its inception, NASA has pushed the boundaries of science and engineering and prided itself on knowing how to manage these engineering innovations. However, pushing the management boundaries requires a careful adaptation of risks, resources, and procedures, and projects must clearly assess the complexities and uncertainties of the task. Too often attempts to resolve errors in these areas ar...

How are humans' subjective judgments of contingencies related to objective contingencies? Work in social psychology and human contingency learning predicts that the greater the frequency of desired outcomes, the greater people's judgments of contingency will be. Second, the learned helplessness theory of depression provides both a strong and a weak prediction concerning the linkage between subj...

This study investigates differential neural activation patterns in response to reward-related feedback depending on various reward contingencies. Three types of reward contingencies were compared: a "gain" contingency (a monetary reward for correct answer/no monetary penalty for incorrect answer); a "lose" contingency (no monetary reward for correct answer/a monetary penalty for incorrect answe...
