The impact of increasing input prices on the U.S. farm sector : a dynamic simulation approach
(1979)
Increasing costs of farm inputs in the last decade have caused much concern among the farm population and agricultural policy makers. In this study a dynamic simulation program of farm sector production and investment ...
A mathematical programming model to recognize conflict in adult education program selection
(1977)
Purpose of the Research. The purpose of the study was to develop a linear programming model to enable adult directors to recognize conflict in adult and continuing education program selections. A quantitative value called ...
Mathematical models of insect movement with emphasis on boll weevil emigration
(1976)
The dispersal from initial residence locations of such insects as the Mexican boll weevil is an important factor in their persistent existence. Insects and other small organisms dispersed from a point of initial concentration ...
The currency-deposit ratio, a market-oriented approach
(1979)
While the currency-deposit ratio plays an important role in monetary economics, only a limited amount of research has been done on it. The work that has been done has approached the subject from the demand side. A ...
A rational approach for incorporating needs into drainage system design
(1978)
The overall goal of this investigation was to develop a methodology for incorporating crop drainage requirements into subsurface drainage design schemes. The methodology developed was linked to the North Carolina State ...
A systems analytic approach to the construction of social indicators
(1977)
In recent years, a desire for better social information has spurred tremendous interest in the development of a satisfactory means of measuring and monitoring social change by means of social indicators. Despite a large ...
A yield model for dryland wheat production
(1971)
Seasonal evapotranspiration from dryland and irrigated wheat plots at Goodwell, Oklahoma during a three year period (1964-1967) could not be adequately described, without the inclusion of a drainage model, from data ...
Optimal grain sorghum irrigation strategies in a dynamic, stochastic environment
(1978)
Agricultural production and associated economic effects of irrigation on the Texas High Plains are seriously threatened by a rapidly declining groundwater supply and a swift upward trend in energy costs. To optimize the ...
A queueing model for the simulation of a port grain elevator
(1978)
Transferring grain from land-based modes of transport to ocean carriers, port elevators represent a substantial portion of the total transportation charges for moving grain from the surplus producing regions of the United ...
