The Princeton Project on National Security describes itself as a “three-year, bi- partisan initiative to develop a sustainable and effective national security strat- egy for the United States of America.” Consisting of the final report and seven working group reports (on Grand Strategic Choices, State Security and Trans- national Threats, Economics and National Security, Reconstruction and Development, Anti-Americanism, Relative Threat Assessment, and Foreign Infrastruc- ture and Global Institutions), this study, like so many others, wrestles with the great unresolved problem that plagues contemporary policy makers and schol- ars: What is the central organizing principle behind American national security policy

Seapower and Space: From the Dawn of the Missile Age toNet-centric Warfare,

This work examines the development of space systems and its implications for naval warfare in the twenty-first century by focusing on the argument that “access to space systems makes possible a new style of warfare.” It addresses the “linked revolution of long-range missiles and their space-based supporting systems.” Furthermore, Friedman seeks to under- stand how the development of space- based systems (notably rockets and satellites) has radically influenced how naval forces conduct navigation, communication, reconnaissance, and targeting. The reality is that modern military forces depend almost entirely on platforms in space to know where they are and to communicate with friendly forces, as well as to know the location of enemy forces and use that information to destroy them. This “rev- olution in military affairs” is now hav- ing an effect on a global scale

Examining AWB’s market power in the international wheat market

The Australian wheat marketing system has been through a number of stages of deregulation in recent years. However, the AWB still maintains the monopoly selling rights of Australian wheat exports. The AWB and its supporters justify the single desk by arguing that the monopoly power enables them to gain a higher price in the export markets. Opposition to the single desk argues that Australia does not produce enough wheat to influence prices. The objective of this study is to test the market power hypothesis by examining the quantity - price relationship of Australian wheat exports and the stability of this relationship over time using annual data from 1961 to 2000.AWB, single desk, wheat marketing, national competition policy, Agricultural and Food Policy, Crop Production/Industries,

The Fate of Dwarf Galaxies in Clusters and the Origin of Intracluster Stars. II. Cosmological Simulations

We combine a N-body simulation algorithm with a subgrid treatment of galaxy formation, mergers, and tidal destruction, and an observed conditional luminosity function Phi(L|M), to study the origin and evolution of galactic and extragalactic light inside a cosmological volume of size (100 Mpc)^3, in a concordance LCDM model. This algorithm simulates the growth of large-scale structures and the formation of clusters, the evolution of the galaxy population in clusters, the destruction of galaxies by mergers and tides, and the evolution of the intracluster light. We find that destruction of galaxies by mergers dominates over destruction by tides by about an order of magnitude at all redshifts. However, tidal destruction is sufficient to produce intracluster light fractions f_ICL that are sufficiently high to match observations. The bulk of the intracluster light (60%) is provided by intermediate galaxies of total masses 10^11 Msun-10^12 Msun and stellar masses 6x10^8 Msun-3x10^10 Msun that were tidally destroyed by even more massive galaxies. The contribution of low-mass galaxies to the intracluster light is small and the contribution of dwarf galaxies is negligible, even though, by numbers, most galaxies that are tidally destroyed are dwarfs. Tracking clusters back in time, we find that their values of f_ICL tend to increase over time, but can experience sudden changes that are sometimes non-monotonic. These changes occur during major mergers involving clusters of comparable masses but very different intracluster luminosities. Most of the tidal destruction events take place in the central regions of clusters. As a result, the intracluster light is more centrally concentrated than the galactic light. Our results support tidal destruction of intermediate-mass galaxies as a plausible scenario for the origin of the intracluster light.Comment: 13 figures, one in color. Accepted for publication in Ap
