In the late 1970s the convective system that is referred to as the bow echo was identified by Fujita (1978). It was identified as a type of convective storm structure associated with intense damaging winds or downburst (Johns 1993). As more of these systems were studied, a better understanding was made on their kinematic structure and dynamical processes. Bow echoes can range in size from 15 km...

Ducted gravity waves are associated with potentially large perturbations in horizontal winds. It may be shown, neglecting friction, that these perturbations are maximized at the surface and minimized at the top of the wave duct, producing perturbation vertical wind shear as well. The magnitude of this shear is maximized in the wave ridge and the wave trough. The perturbation shear may be signif...

The 1997 Indonesian financial crisis resulted in severe economic dislocation and political upheaval, and the detrimental consequences for economic welfare, physical health, and child education have been established in several studies. The crisis also adversely impacted the psychological well-being of the Indonesian population. Comparing responses of the same individuals interviewed before and a...

We test a simple model of exchange rate regime choice with data for 65 non-OECD countries covering the period 1980-94. We find that the variance of output at home and in potential target countries as well as the correlation between home and foreign real activity are powerful and robust predictors of exchange rate regime choice. Surprisingly, a more volatile foreign economy can be an argument in...

Objective: Recent studies have begun to look at the impact of the economic crisis on mental health. This paper tries to summarize the most important findings with regard to effects of the economic crisis on mental health in Spain on the basis of a comprehensive literature review. Results: Most of the studies agree on the negative consequences on mental health of the Spanish economic crisis. A d...

Banking regulation and supervision were designed to protect banks from failure, but this did not avoid the large number of banking crises recently experienced by OECD countries. Using binary response models for panel data and centering on OECD countries, this paper emphasizes the poor influence of regulation and supervision on banks’ soundness and presents the main determinants of banking crise...

In this paper we consider the conflicts between two traditions of political ecology. The two traditions might be crudely characterised as physicalist and culturalist. The first is apparent in much of the work in ecological economics in particular, but also in the materialist left and more practically in conservation policy. It is concerned with the physical and biophysical conditions for human ...
