Currently, there exist a large number of superb digital librari-es (DLs), all of which are, unfortunately, vertically integrated and all presenting a monolithic interface to their users. Ideally, a user would want to locate resources from a variety of digital libraries dealing only with one interface. A number of approa-ches to this interoperability issue exist including: defining a u-niversal protocol for all libraries to adhere to; or developing mechanisms to translate between protocols.

Once in digital form, the information in question can be stored, processed and displayed by a computer. Furthermore, it can readily and rapidly be transmitted from one computer to any other computer regardless of distance, political frontiers, and physical obstacles. From a digital point of view, there is absolutely no distinction between text, sounds, graphics, photographs, music, animations, videos and…software. To include software... Ver mais

RUSSIA'S PROMISING FUTURE

STOCK OPTIONS

Twenty years ago, the biggest component of executive compensation was cash, in the form of salaries and bonuses. Stock options were just a footnote. Now the reverse is true. With astounding speed, stock option grants have come to dominate the pay - and often the wealth - of top executives throughout the United States. Last year, Jack Welch's unexercised GE options were valued at more than $260 million. Intel CEO Craig Barrett's were worth more than $100 million. Michael Eisner exercised 22 million options on Disney stock in 1988 alone, netting more than a half-billion dollars. In total, U.S. executives hold unexercised options worth tens of billions of dollars.... Ver mais
