    In the corporate world, IT consultancies are unique. They provide professional services to clients, like most consultants. But unlike many consultant fields, IT consultants also commonly develop the technological tools their clients need to improve their business operations. This business model allows IT consultants to flexibly redesign business processes that achieve client objectives, because these business processes can evolve hand-in-hand with the IT tools. However, these two workloads - developing the tools and providing the professional services - often conflict within the inner workings of the IT consultancy. View full abstract»

    Cryptography is one of the most active areas of research in computer science. It survives only where efforts to reduce computational complexity have failed, because the intractability of various problems keeps unwanted intruders at bay. Predicting its future, however, is difficult. Researchers are constantly devising new cryptosystems that are often based on new, untested intractability assumptions. For every cipher that a cryptanalyst breaks, two more seem to sprout up in its place. Despite the fact that revolutionary discoveries in algorithmics might render entire classes of cryptosystems obsolete overnight, the field likely will continue to survive due to its breadth and diversity alone.

    US brokerage firms have shown strong interest in a new alternative for trading of equity options since the 26 May 2000 launch of the International Securities Exchange (ISE), an all-electronic trading platform. Although the collective impact of these adoption decisions led to a successful launch and a formidable competitor to the four established options markets in the US, major brokerage firms differ widely in their usage and adoption rates.
