Recent Royal Aircraft Establishment research on gusts has been particularly concerned with severe gusts and the situations in which they occur. In the stratosphere, mountain wave conditions and the vicinity of thunderstorm tops have been investigated. A t lower altitudes, gusts in and near thunderstorms have also been studied, as have wind and gust effects likely t o be significant during takeo...
We analyze non-cooperative environmental policy when the only strategic interaction between countries is through bilateral transboundary pollution, i.e., countries are closed or small open economies. When countries set pollution taxes simultaneously, there is no carbon leakage. However, in the sequential-move game, the leader sets its pollution tax lower than the marginal damage from own pollut...
We have previously presented 5.7 σ evidence for a smaller α at redshifts 0.2 < zabs < 3.7 from a sample of 128 Keck/HIRES quasar absorption systems: α/α = (−0.57 ± 0.10) × 10−5. A non-zero α/α manifests itself as a distinct pattern of shifts in the measured absorption line wavelengths. The statistical error is now small: we do detect small line shifts in the HIRES data. Whether these shifts are...
Standard search and matching models of equilibrium unemployment, once properly calibrated, can generate only a small amount of frictional wage dispersion, i.e., wage differentials among ex-ante similar workers induced purely by search frictions. We derive this result for a specific measure of wage dispersion—the ratio between the average wage and the lowest (reservation) wage paid. We show that...
Wage inequality in the United States has grown substantially in the past two decades. Standard supply-demand analysis in the empirics of inequality (e.g. Katz and Murphy (1992)) indicates that we may attribute some of this trend to an outward shift in the demand for high skilled labor. In this paper we examine a simple static channel in which the wage premium for skill may grow increased firm e...
Hydrocarbon contamination of unsaturated soils has been a serious environmental problem for decades. Two of the most common methods of remediating these sites are soil vapour extraction (SVE) and bioventing. Predictive models have been developed for the SVE and bioventing processes in order to estimate mass transfer coefficients for experimental systems and clean up times for field sites. These...
The impact of manufacturing transfer in Jiangsu province, China, on the spatial-temporal variations of SO2 emissions is investigated using estimated sector-specific SO2 emissions, and emissions in the different transfer-in and transfer-out regions were quantified during 2000–2011. Our results show that SO2 emissions had undergone three phases: an increase in the period of 2000–2005, a rapid dec...
It is by now established that neutrinos mix, have (different) non-zero masses, and therefore oscillate. The oscillation parameters themselves, however, are not all well-known. An open problem is that of the neutrino mass hierarchy. We study the possibility of determining the neutrino mass hierarchy with atmospheric neutrinos using an iron calorimeter detector capable of charge identification su...
