Manufacturing Growth, Technological Progress, and Military Expenditure
During the Cold War a major justification of high levels of military spending was the âspin offâ of innovations to the civil sector, such as computers, which could then be exploited profitably and to the benefit of the economy and society. There is evidence that this has changed in more recent times, with the speed of consumer industry led technological change leading to âspin inâ to advanced weapons systems. If this is the case it has removed a major benefit of military spending. There is, however, little systematic evidence and little recent empirical work. This paper makes a contribution to the debate, analysing the impact of military spending on technological progress, and hence labour productivity and economic growth, for a number of major weapons producers. It uses data on the manufacturing sector, for the period 1966-2002 and estimates a CES production function in which military spending is assumed to effect growth through its impact on trend technological change.
Comparisons in Gender Wage Differentials and Discrimination between Germany and the United Kingdom
Due to the lack of consistent data, direct and robust comparisons of cross-country labour markets have been virtually impossible. This study uses a new panel data series that controls for inconsistencies, thus overcoming this problem. This study estimates gender wage differentials and gender discrimination in the German and United Kingdom labour markets. Panel estimates are used to identify general wage differences between the two countries, with cross-sectional comparisons undertaken to identify changes that have occurred between 1991 and 1993, that are consistent with known labour market policies. It is found that gender wage differentials are greater in the UK than Germany with employer discrimination against females attributed with the majority of the difference in both countries.

The Shifted Coupled Cluster Method: A New Approach to Hamiltonian Lattice Gauge Theories
It is shown how to adapt the non-perturbative coupled cluster method of
many-body theory so that it may be successfully applied to Hamiltonian lattice
gauge theories. The procedure involves first writing the wavefunctions
for the vacuum and excited states in terms of linked clusters of gauge
invariant excitations of the strong coupling vacuum. The fundamental
approximation scheme then consists of i) a truncation of the infinite set of
clusters in the wavefunctions according to their geometric {\em size}, with all
larger clusters appearing in the Schr\"odinger equations simply discarded, ii)
an expansion of the truncated wavefunctions in terms of the remaining clusters
rearranged, or ``shifted'', to describe gauge invariant {\em fluctuations}
about their vacuum expectation values. The resulting non-linear truncated
Schr\"odinger equations are then solved self-consistently and exactly. Results
are presented for the case of in space-time dimensions.Comment: 13 pages + 5 postscript figures, plain Late
The localized Delaunay triangulation and ad-hoc routing in heterogeneous environments
Ad-Hoc Wireless routing has become an important area of research in the last few years due to the massive increase in wireless devices. Computational Geometry is relevant in attempts to build stable, low power routing schemes. It is only recently, however, that models have been expanded to consider devices with a non-uniform broadcast range, and few properties are known. In particular, we find, via both theoretical and experimental methods, extremal properties for the Localized Delaunay Triangulation over the Mutual Inclusion Graph. We also provide a distributed, sub-quadratic algorithm for the generation of the structure
Laser Based Underwater Communication Systems
We report on recent progress in the field of visible light communications including direct modulation of blue laser devices at data rates beyond 10 Gbit/s, and the transmission of 2.5 Gbit/s OOK data through water. We also discuss the advantages of operating with single mode laser devices and matched filtering at the receiver in the context of applications with significant solar background. The system performance for two types of direct-detection receivers, a PIN detector and less conventional silicon Photomultiplier technology will be presented
