Weak decays of particles containing heavy quarks: At SLAC, KEK and Fermilab, a concerted experimental effort has been made to determine elements of the Cabibbo-Kobayashi-Maskawa (CKM) matrix through studies of the mixings and decays of B mesons. In addition, the properties of D mesons have been measured to high accuracy in the CLEO-c Program at Cornell. Work in this area continues at Fermilab, ...

Choice functions on tournaments always select the maximal element (Condorcet winner), provided they exist, but this property does not hold in the more general case of weak tournaments. In this paper we analyze the relationship between the usual choice functions and the set of maximal elements in weak tournaments. We introduce choice functions selecting maximal elements, whenever they exist. Mor...

Policymakers in developing countries have increasingly pinned their hopes on bilateral investment treaties (BITs) in order to improve their chances in the worldwide competition for foreign direct investment (FDI). However, the effectiveness of BITs in inducing higher FDI inflows is still open to debate. It is in several ways that we attempt to clarify the inconclusive empirical findings of earl...

One of the original goals of intelligent educational systems was to guide each student to the most appropriate educational content. In previous studies, we explored both knowledge-based and social guidance approaches and learned that each has a weak side. In the present work, we have explored the idea of combining social guidance with more traditional knowledge-based guidance systems in hopes o...
