We explore several problems related to ruled polygons. Given a ruling of a polygon P , we consider the Reeb graph of P induced by the ruling. We define the Reeb complexity of P , which roughly equates to the minimum number of points necessary to support P . We give asymptotically tight bounds on the Reeb complexity that are also tight up to a small additive constant. When restricted to the set ...

The well-established negative correlation between staggered boards (SBs) and firm value could be due to SBs leading to lower value or a reflection of low-value firms’ greater propensity to maintain SBs. We analyze the causal question using a natural experiment involving two Delaware court rulings–separated by several weeks and going in opposite directions–that affected the antitakeover force of...

The foundations of ethical principles in the Eastern Mediterranean Region can be found within the 3 major religions of the Region; Judaism, Christianity and Islam.
