The level 1 highest weight modules of the quantum affine algebra Uq(ŝln) can be described as spaces of certain semi-infinite wedges. Using a q-antisymmetrization procedure, these semi-infinite wedges can be realized inside an infinite tensor product of evaluation modules. This realization gives rise to simple descriptions of vertex operators and (up to a scalar function) their compositions. 1 R...

THE EARLIEST KEYNES LECTURES tended to be on Keynesian subjects, either Keynes himself or the parts of economics on which he was a major influence. More recently that habit of piety has weakened or disappeared. I intend to go back to it, but not in the sense that I will be concerned with what Keynes or later Keynesians thought about this or that. The connection is more abstract. The macroeconom...

This study aimed to explore non-verbal executive processes in simultaneous interpreters. Simultaneous interpreters, bilinguals without any training in simultaneous interpreting, and control monolinguals performed the Wisconsin card sorting task (WCST; Experiment 1) and the Simon task (Experiment 2). Performance on WCST was thought to index cognitive flexibility while Simon task performance was ...

This study investigates the value of the strategic flexibility provided by firms’ international investments during an economic crisis, defined here as an unanticipated significant downturn in the economy. To avoid below-par performance, firms need to adapt quickly to this significant change in their environment, making real options very valuable to them. Although firms’ international investment...

The growing importance of enterprise risk management and the resulting integration efforts put the need for separate IT risk management frameworks in question. In this research we analyse common and distinct elements of the COSO enterprise risk management and ISACA Risk IT frameworks. The analysis affirms the hypothesis that separate IT risk management frameworks are redundant.
