Apparent attenuation associated with seismic wave interference in two-component cyclic stratification
(1980)
Interference effects and dissipation produce frequency selective attenuation. In a one-dimensional stratified medium the observed attenuation is a composite of the apparent attenuation arising from interference effects and ...
Antecedents of role conflict and role ambiguity in the National Park Service
(1980)
The purpose of this research was twofold: (1) to conduct a comprehensive study of the antecedents of role conflict and role ambiguity, and (2) to extend this research to public agencies managing natural resources, which ...
The effect of forage utilization on the grain yield of wheat
(1980)
Wheat (Triticum aestiuum L. em. Thell.) is used as both a grain and a forage crop throughout Texas. It is the general practice to graze wheat during the winter, remove the cattle in the spring and allow the wheat to produce ...
Effect of volatiles on seismic attenuation and velocity in sedimentary rocks
(1980)
Small amounts of water can have a dramatic effect on the seismic quality factor, Q; this suggests the importance of controlling the environment in which Q measurements are made. Because the effect of moisture is so large, ...
A test of the equilibrium Hoover Index of concentration in analysing the trends and patterns of spatial population distribution in Korea
(1980)
The main objective of this dissertation is to investigate systematically the changing patterns and trends of area population distribution in Korea, and to study the implications these spatial patterns of population ...
Recreation lock congestion : developing resource management measures
(1980)
The purpose of this study was to analyze 1977 survey data collected on the Upper Mississippi River to determine its potential to formulate effective management measures to help reduce congestion problems associated with ...
An alternative to disengagement theory : its value in explaining the Texas winter visitor phenomenon
(1980)
This exploratory study had the following objectives (1) to assess the utility of Hochschild's alternative (neo) theory for explaining the aging process among a sub-population of aging adults specifically, winter visitors ...
The ion-exchange and catalytic properties of titanium phosphates and mixed titanium-zirconium phosphates
(1980)
[alpha]-Titanium phosphate, Ti(HPO4)2 * H2O, has layered structure isomorphous with [alpha]-zirconium phosphate, Zr(HPO4)2 * H2O. Thus, solid solutions of the two compounds were prepared and their properties correlated ...
The agrarian values of Mormonism : a touch of the mountain sod
(1980)
Mormons and the agrarian West seem to be almost synonymous to some. The Mormon use of irrigation is internationally known and provides a benchmark in the history of the American West. While much work has been done regarding ...
The statistical effects of the misidentification of selected stationary time series models
(1980)
Time-series designs are becoming more popular in the behavioral sciences, and the interrupted-time-quasi-experiment has shown a great deal of flexibility in single-subject and group designs. However, the question of which ...
