We reconstructed oxygenation changes in the Oxygen Minimum Zone of the upwelling ecosystem off Concepción (36° S), Chile, using inorganic and organic proxies in a sediment core covering the last ca. 110 years of sedimentation in this area. Authigenic enrichments of Mo, U and Cd were observed between ca. 1935–1971...

El Salvador's land resources are intensively cultivated.
Labor is relatively abundant and wages are low. This study
analyzed the effects of government policies and observed farm
price distortions on enterprise/weed control system choices
and associated income-employment effects.
A regional linear programming framework was employed to
analyze the effects of alternative...
