The rapid growth of the World Wide Web has resulted in more data being accessed over the Internet. In turn there is an increase in the use of semistructured data, which plays a crucial role in many web applications particularly with the introduction of XML and its related technologies. This increase in use makes the design of good semistructured data(More)
Many firms deploy takeover defenses at the time of their IPOs, although at significantly lower rates than for seasoned corporations. We find that IPO managers deploy takeover defenses particularly when their compensation is high, shareholdings are small, and the oversight from non-managerial shareholders is weak. We also find that the presence of a takeover(More)
The rapid growth of the World Wide Web has resulted in a dramatic increase in semistructured data usage. This creates a growing need for ensuring consistency of the data especially when applications or databases change the schema of semistructured data. In this paper, we demonstrate an approach to formally define and verify the ORA-SS data model for(More)

We test recent theories of when companies go public which predict that 1) more companies will go public when outside valuations are high or have increased, 2) companies prefer going public when uncertainty about their future profitability is high, and 3) firms whose controlling shareholders enjoy large private benefits of control are less likely to go(More)
The dramatic expansion of semistructured data has led to the development of database systems for manipulating the data. Despite its huge potential, there is still a lack of formality and verification support in the design of good semistructured databases. Like traditional database systems, developed semistructured database systems should contain minimal(More)
