User Defined Types and Nested Tables in Object Relational Databases

Bernadette Byrne, Mary Garvey, ‘User Defined Types and Nested Tables in Object Relational Databases’, paper presented at the United Kingdom Academy for Information Systems 2006: Putting Theory into Practice, Cheltenham, UK, 5-7 June, 2006.There has been much research and work into incorporating objects into databases with a number of object databases being developed in the 1980s and 1990s. During the 1990s the concept of object relational databases became popular, with object extensions to the relational model. As a result, several relational databases have added such extensions. There has been little in the way of formal evaluation of object relational extensions to commercial database systems. In this work an airline flight logging system, a real-world database application, was taken and a database developed using a regular relational database and again using object relational extensions, allowing the evaluation of the relational extensions.Peer reviewe

Adaption of space station technology for lunar operations

Space Station Freedom technology will have the potential for numerous applications in an early lunar base program. The benefits of utilizing station technology in such a fashion include reduced development and facility costs for lunar base systems, shorter schedules, and verification of such technology through space station experience. This paper presents an assessment of opportunities for using station technology in a lunar base program, particularly in the lander/ascent vehicles and surface modules

Prosecutorial Discretion in Immigration Enforcement: Legal Issues

This report begins by discussing the sources of federal power to regulate immigration and, particularly, the allocation of power between Congress and the President in this area. It next addresses the constitutional and other foundations for the doctrine of prosecutorial discretion, as well as the potential ways in which prosecutorial discretion may be exercised in the immigration context. It concludes by addressing potential constitutional, statutory, and administrative constraints upon the exercise of prosecutorial discretion. The report does not address other aspects of discretion in immigration law, such as the discretion exercised by immigration officers in granting benefits (e.g., asylum), or by immigration judges in non-enforcement contexts (e.g., cancellation of removal)

Executive Orders: Issuance, Modification, and Revocation

Executive orders, presidential memoranda, and proclamations are used extensively by Presidents to achieve policy goals, set uniform standards for managing the executive branch, or outline a policy view intended to influence the behavior of private citizens. The U.S. Constitution does not define these presidential instruments and does not explicitly vest the President with the authority to issue them. Nonetheless, such orders are accepted as an inherent aspect of presidential power. Moreover, if they are based on appropriate authority, they have the force and effect of law. This report discusses the nature of these written instruments, executive orders in particular, with a focus on the scope of presidential authority to execute such instruments, as well as judicial and congressional responses to their issuance

East Asian Steel Projections for the 1990s Revisited

In 1989 a research team from the AustraliaJapan Research Centre (AJRC) undertook a study of the prospects for the East Asian steel industry for the 1990s. The aim was to assess the impact of developments in the region on industry strategies in Australia. This paper reviews those projections to see whether they were right or wrong. It also examines the growth of the East Asian industry over the last decade in the context of developments in the industry worldwide and reviews Australias position in regional iron ore and coal markets during the 1990s. The central focus of the AJRC study was on what opportunities might emerge in Australia for the supply of processed steel product to the East Asian region in the 1990s. The main conclusion was that East Asia would shift from being a long-time and significant net exporter of steel product to the rest of the world to being a significant net importer of steel product, given then established trends in production, consumption and trade. At the time, this was a radical conclusion. It had an important impact on thinking about trends in the regional steel market in Australia, in Japan and elsewhere in East Asia. The main conclusions of the AJRC study turned out to be correct. The industry did not adjust to the pressures in the market exactly as predicted, partly because of the financial crisis in East Asia and Japans domestic stagnation. However, the conclusions about the growth of China and its impact on regional steel trade were particularly prescient. In the last decade, China has become the worlds largest producer and consumer of steel while Japanese consumption and production have contracted. Both South Korea and Taiwan have increased their shares of production and consumption of steel. Australia has entrenched its position as the dominant supplier of iron ore and coking products to East Asia.steel, Projections, East Asia, Japan, Australia, iron ore, regional steel market
