T here have been three great revolutions in computing technology during the past 50 years: the stored-program computer, high-level languages, and component-level programming. Although working programmers are well aware of this last revolution, it seems to have escaped the notice of most everyone else. Academic researchers are doing little or nothing that touches the subject, and apart from trad...

Object-oriented (OO) software engineering techniques are often used with programming languages, but they also apply to relational databases. OO techniques are not only helpful for determining database structure, but also for designing stored procedure code. In fact, we were surprised by the magnitude of the stored procedure benefits. OO techniques boost development productivity as well as the q...

An efficient partitioning scheme based on current capability of MOS MSI technology was evolved in which four functional building blocks were defined for implementing computer digital architecture. The partitioning employs a bit slice concept to define registers and a universal logic gate for general twoor three-variable logic. A look-ahead carry for fast arithmetic and a heavily buffered OR gat...

This paper examines how the ability of media firms to engage in targeted advertising has changed with increased competition from online channels. We find that the use of the Internet by magazine readers, as well as the availability of companion websites, increase the value of targeted advertising. This indicates a complementarity between offline and online media with respect to targeting. We pr...

In role-based access control (RBAC) permissions are associated with roles, and users are made members of appropriate roles thereby acquiring the roles’ permissions. The principal motivation behind RBAC is to simplify administration. An appealing possibility is to use RBAC itself to manage RBAC, to further provide administrative convenience. In this paper we investigate one aspect of RBAC admini...

For a company with many databases in different data models, it is necessary to consolidate them into one data model interchangeable and present data in one data model concurrently to users. The benefit is to let user stick to his/her own data model to access database in another data model. This paper presents a semantic metadata to preserve database constraints for data materialization to suppo...

The rapid advance of computing technology since the 1940s has created an impression that all that happened in computing before then was somehow mere prologue to the real history. According to this popular notion, the computer age began with the invention of machines that computed at electronic speeds, that were capable of automatic sequence control with conditional branching, and that stored th...

Research over the last 25 years has identified a number of features of programs for justice-involved individuals that consistently predict better outcomes. The challenge for programs comes in translating this research into useful practices for their specific context. This study describes the development and pilot testing of a web-based self-report program classification and assessment tool. The...

Stored-program computers have not yet been used in small scientific spacecraft. The evolution of spacecraft data systems indicates that inclusion of a computer is a logical next step. The computer would be used for four types of computation: buffering data, formatting data, redundancy removal, and parameter extraction. The most important advantage of using a computer is the flexibility obtained...

Eukaryotic precursor-messenger RNAs (pre-mRNAs) undergo splicing to remove intragenic regions (introns) and ligate expressed regions (exons) together. Unlike exons in the mature messenger RNAs (mRNAs) that are used for translation, introns that are spliced out of pre-mRNAs were generally believed to lack function and to be degraded. However, recent studies have revealed that a large group of sp...
