The U.S. Westward Expansion
The U.S. economic development in the nineteenth century is characterized by the westward movement of population and the accumulation of productive land in the West. What are the quantitatively important forces driving this phenomena? This paper presents a model of migration and land improvement, to address this question. Counterfactual experiments reveals that two forces are key in accounting f...
متن کاملEnvironmental Variability and Energetic Adaptability of the Great Scallop, Pecten Maximus, Facing Climate Change Environmental Variability and Energetic Adaptability of the Great Scallop, Pecten Maximus, Facing Climate Change
We developed a full life-cycle bioenergetic model for the great scallop P. maximus relying on the concepts of the Dynamic Energy Budget (DEB) theory. The covariation method was implemented to estimate the parameters of a standard deb model. Such models are able to predict various metabolic processes from a food availability marker and temperature in the environment. However, suspension-feeders ...
متن کاملAdiabatic westward drift of Indian monsoon depressions
A large fraction of the rain received by continental India is produced by cyclonic vortices with outer radii of about 1,000 km that are contained within the larger scale South Asian monsoon flow. The more intense occurrences of these vortices are called monsoon depressions; these consist of bottom-heavy columns of relative vorticity that propagate to the northwest in time-mean low-level eastwar...
متن کاملA westward extension of the warm pool leads to a westward extension of the Walker circulation, drying eastern Africa
Observations and simulations link anthropogenic greenhouse and aerosol emissions with rapidly increasing Indian Ocean sea surface temperatures (SSTs). Over the past 60 years, the Indian Ocean warmed two to three times faster than the central tropical Pacific, extending the tropical warm pool to the west by *40 longitude ([4,000 km). This propensity toward rapid warming in the Indian Ocean has b...
متن کاملCurrent Welfare Problems Facing Horses in Great Britain as Identified by Equine Stakeholders
Despite growing concerns about the welfare of horses in Great Britain (GB) there has been little surveillance of the welfare status of the horse population. Consequently we have limited knowledge of the range of welfare problems experienced by horses in GB and the situations in which poor welfare occurs. Thirty-one in-depth interviews were conducted with a cross -section of equine stakeholders,...
