T-Duality and Non-Local Realizations of Supersymmetry in String Theory

We study non-local realizations of extended worldsheet supersymmetries and the associated space-time supersymmetries which arise under a T-duality transformation. These non-local effects appear when the supersymmetries do not commute with the isometry with respect to which T-duality is performed.Comment: 6 pages, Latex, Talk presented at the Workshop on Strings, Gravity and Related Topics, Trieste, 29-30 June 199

LEVERAGING SOA IN BANKING SYSTEMS INTEGRATION

There is no doubt that the systems integration is one of the most important and complicated tasks in software filed especially for complex applications like banking systems. Complexity in integrating banking systems often comes from continues changes in both technical and business features provided by them to meet customer needs. Banking systems always come from different software vendors which mean using platforms and different design and architecture patterns, and this for sure adds extra complexity for integrating them. Serviceoriented architecture (SOA) is a promising method in software filed that aims to build or restructure software systems in a manner that makes their maintenance and integration easier. Agility is the most important goal that should be achieved when building and integrating banking systems. Simply, agility is needed to meet market needs quickly and efficiently and SOA is the way that could provide itSOA, SOI, P2P Integration, Web Services, and Legacy Code

Performance-Based Long Term Incentive Compensation and Firm Performance

Awarding executives long-term incentive pay based on firm performance is often described as a natural way to improve firm performance. This brief uses an analytical approach to examine that proposed relationship. We first document the prevalence of performance-based long-term incentive (PB LTI) measures and the trends in the relative size of these measures compared to aggregate measures of compensation. We then compare the characteristics and performance of firms that have implemented a PB LTI measure in the past to those that have not. In order to understand the impact of PB LTI awards on firm performance, we separately assess the roles of the existence of the PB LTI measures, the relative size of the measures, and the type of PB LTI measure on firm performance
