Perceptions of recreation and park user fees in Austin, Texas
(1981)
A study, co-sponsored by the Texas Recreation and Park Society, was conducted in Austin, Texas, during the summer of 1980. Its purpose was to compare and contrast public attitudes concerning public recreation user fees ...
Distribution of the crustacean zooplankton in a subtropical estuarine system : implications for the predator-prey interaction between the primary and secondary consumers
(1981)
The spring and summer zooplankton community in East Lagoon, Galveston Island, Texas was similar to the summer assemblages of many U.S. estuaries. Species diversity was low and the crustacean zooplankton were dominated by ...
Clay fabric of gassy submarine sediments
(1981)
The research presented herein is a new design and development of a special methodology to delineate the nature of clay fabric in natural sediments under in situ downhole pressure conditions using pressurized core barrel ...
The effect of different processing technologies in the blue crab (Callinectes sapidus) industry on microbiological and textural properties and thermal processing efficiency
(1981)
The processing technologies currently practiced in the blue crab industry are much the same as they were 50 years ago. Consequently, much of the industry is very labor intensive which results in processing and sanitation ...
Forecasting inventory prices for purchasing decisions using multiple regression techniques
(1981)
The focus of this research was on developing a technique for forecasting prices to use in making inventory purchase decisions. The basic tool used to develop the forecasts was multiple regression analysis. The technique ...
Comparative valve morphology of selected species of Eunotia Ehr. (Bacillariophyceae)
(1981)
The valve morphology of twenty four taxa of the genus Eunotia from Texas and Alaska was examined with the light and scanning electron microscopes with particular emphasis on the terminal nodules, raphe, hyaline areas, ...
A generalized approach to the two sample problem : the quantile approach
(1981)
Parzen (1979) suggests a location and scale model for the quantile function (inverse distribution function) of a random variable. We extend this model to the two sample and k-sample problems and some results are given ...
A study of the administrative tasks and functions of the director of biomedical communications as perceived by the director and his administrative superior
(1981)
The purposes of this study were threefold: (1)to verify and clarify a set of administrative tasks and functions common to directors of biomedical communications, (2)to compare the perceptions of the directors and their ...
Citizen participation and communication technologies
(1981)
This study aims to strengthen the scientific credibility of the use of communication technologies--television and, ultimately, satellite and cable systems--as tools for stimulating public participation in the urban policy ...
Economic evaluation of whole-tree chip harvesting operations through simulation
(1981)
A discrete, stochastic simulation model was developed to simulate and evaluate chip harvesting systems. FSCAT, an acronym which stands for felling, skidding, chipping and trucking, was written in modular form with the ...
