ABSTRACT We examine how non‐CEO executives (NCEs) serving on outside boards affect their focal firm performance. Firms with such NCEs exhibit lower return on asset (ROA) and profit margins than those without. These effects begin after board service starts, are not explained by busy boards or CEOs, and persist at least a year.

Testing and Debugging Techniques for Answer Set Solver Development
This paper develops automated testing and debugging techniques for answer set solver development. We describe a flexible grammar-based black-box ASP fuzz testing tool which is able to reveal various defects such as unsound and incomplete behavior, i.e ...

Strategic Flip‐Flopping in Political Competition
ABSTRACT We study candidates' position adjustments in response to information about voters' preferences. Repositioning allows candidates to move closer to the median voter, but it incurs financial and electoral costs. In a subgame‐perfect equilibrium, candidates diverge from the center ex ante if the costs of adjustment are sufficiently large.

This perspective article considers what computations optical computing can and should enable. Focusing upon free‐space optical computing, it argues that a codesign approach whereby materials, devices, architectures, and algorithms are simultaneously optimized is needed.

Defeasible Reasoning in Islamic Legal Theory
There is a common understanding among logicians today that nonmonotonic types of reasoning, such as defeasible or presumptive, can clearly warrant a rational acceptance of its conclusion.

Randomized Hypergraph States and Their Entanglement Properties
Randomized hypergraph (RH) states are mixed states that extend the concept of randomized graph states to multi‐qubit hypergraphs subject to probabilistic gate imperfections. By modeling noisy multi‐qubit operations, this work reveals nonmonotonic behavior in bipartite and multipartite entanglement, derives analytical witnesses for specific hypergraph ...

Logical Omnipotence and Two notions of Implicit Belief [PDF]
The most widespread models of rational reasoners (the model based on modal epistemic logic and the model based on probability theory) exhibit the problem of logical omniscience.

Logical problems with nonmonotonicity
A few years ago, believing that human thinking is nonmonotonic, I tried to reconstruct a nonmonotonic reasoning by application of two monotonic procedures. I called them “step forward” and “step backward” (see [4]). The first procedure is just a consequence operation responsible for an extension of the set of beliefs.

Field‐free magnetization switching is achieved in WTe2/Fe3GeTe2/WTe2 heterostructures by exploiting WTe2's strong charge‐to‐spin conversion. The switching behavior is independent of the crystallographic orientation of the pulse current, enabling robust operation in perpendicular and parallel configurations.
