All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The setting for this longitudinal cost-quality study was unique insofar as it provided the rare opportunity to involve a district that had undergone a "rags to riches" transition during the past decade.

The purpose of the study was twofold: (1) To report changes in the "learning opportunities" that were brought about as a result of money. (2) To determine if the per pupil expenditure level had any influence on the learning opportunities of pupils in the San Juan School District, as measured by the achievement gains on the California Achievement Test.

Three hypotheses were tested, all of which hypothesized that …

Weber Basin Water Conservancy District: An Economic Appraisal, Dilipsinha C. Pendse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Information on Water Conservancy Districts in Utah was collected by mail and personal visits to district offices. There are a total of 12 districts in Utah, but only five were selling water in 1965. The water development projects of the remaining seven were not finished. Some of the districts are small and consolidation would bring them many advantages of large scale operation.

The success of the Weber Basin Water Conservancy District was evaluated from the point of view of economic efficiency. Insistence on long term contract, adherence to water duty requirements set by the Bureau of Reclamation, inability to sell …

Seasonal, Diurnal And Species Variation In Forage Moisture Content In Relation To Site On Mountain Summer Range Of Northern Utah, Chaudhry Mohammad Sharif

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Practical assessments of range production and utilization are based on forage weight estimates. In preparing these estimates moisture content in green vegetation offers some problems. The moisture component is not likely to be constant for a given species. Diurnal, seasonal and site variability have been well illustrated for agronomic and tree species (Salisbury, 1848; Jenkins, 1879; Miller, 1917; Pearson, 1924; Watkins, 1940; Parker, 1951; Ackley, 1954; Werner, 1954; Zohary and Orshan, 1956; Slatyer, 1959; Kozlowaki, 1965 and Jame son, 1966). Since variability is also likely for range plants, computations made on green weights are apt to be fallacious. It is …

Although no modeling is carried out, Cache County is used as a foundation for judging the technique within this thesis.

Of the several approaches to simulation which were reviewed, Forrester's (1961) methods, and the use of DYNAMO as a simulation …

Description And Evaluation Of Institutions Involved In Water Allocation And Distribution In Utah, Kimber C. Webb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water development and allocation have been among the most important problems Utah has had to face throughout the past 117 years of development . When Utah's first white settlers, the Mormon pioneers, entered Salt Lake Valley in July of 1847, little met their eyes to entice their stay. The earth was so parched and dry that they were unable to scratch the surface with their plows. Less than two hours after their arrival members of the party began digging ditches and building dams to irrigate and soften the earth so they could begin plowing.

An Evaluation Of The Dichotomy Between Structural Versus Deficient-Demand Unemployment, Carl D. Parker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is addressed to the theoretical controversy which revolves around the explanation of the higher unemployment rates that prevailed after 1957. The debate that has been generated concerning the causes of this unemployment problem is usually referred to as the "structural" versus "deficient-demand" debate. An attempt is made to present a representative view of both sides of the debate as well as a critical evaluation of both positions. Care is taken to keep both positions separated for each leads to entirely different policy recommendations. A more general theoretical structure is presented which will be useful in analyzing the relevance …

Some Methodological Problems In The Economic Appraisal Of Increments Of Irrigation Water, David L. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A multiple regression model using 12 linear, 12 nonlinear, and 7 interaction terms was employed. A coefficient of determination of .70 was obtained for the model. Intercorrelation problems associated with the model limit its usefulness for economic and predictive purposes. The predictive value of the model was greatly increased by reducing the number of correlated variables included in the model. …

Economic Analysis Of An Iranian Water Development: The Sefeed Rood Project, Malek M. Mohtadi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is an evaluation of the methods and assumptions employed by those groups responsible for preparation of the original benefit/cost data describing the Sefeed Rood project. Benefit/cost ratios reported by the French engineering firm, Cotha Sogreah, and Plan Organization in a joint study range from 2:1 to 2.6:1 (6 and 10). A priori these seem suspect since the dam plus necessary canals and diversion works are obviously large and costly and only primary benefits are considered. The question is whether the potential benefits are likely to ever yield a positive return on investment and, if so, how long a …

The Adolescents Preference For Counselors In Relation To Their Degree Of Religious Conviction, James W. Fitch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In a highly complex culture, there are numerous factors that influence ones life. The more industrialized societies promote tremendous structure for the entire population. The past World War II era has been labeled "The Age of Anxiety" (28, p.3). In some respects children are being forced to mature at an earlier age. The "storm and stress" period of the adolescent is receiving considerable recognition in our current literature and the adults are taking on increasing amounts of structure which are all resulting in more complex culture.

Movement Of Atrazine In Soil Under Furrow Irrigation, Jyothi Veerabhadrappa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Movement of atrazine in response to furrow irrigations was studied using the samples of Timpanogos silt loam soil. Distribution in soil profile of surface applied herbicide was determined by drawing samples of water extracts through porous cylinders. Atrazine quantity was determined by spectrophotometer.

It was observed that the herbicide found in the water extracts was an indication of the quantity present in the soil. The herbicide moved readily with the applied water. Irreversible thermodynamic model could not be applied because of the initial and final boundary conditions. The pattern of movement was in conformity with the chromatographic theory.

Comparative Effects Of Dehydration Processes On Physico-Chemical Changes In Fruits, Chang Yong Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Drying with the help of sun and wind is one of the oldest methods of food preservation known to man, but artificial drying, or dehydration, has been developed and used extensively only during the last two decades. The problem in dehydration is that the water content must be decreased sufficiently to maintain the stability of the product by retarding the rates of deteriorative biochemical, microbiological, and enzymatic reactions during subsequent storage. At the same time irreversible changes should not be brought about.

A Comparison Of Two Non-Verbal Intelligence Tests As Predictors Of Academic Success Of Navajo Students, Stanford S. Larson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was a search for a valid and reliable tool for the measurement and appraisal of the Navajo student at Intermountain School whose cultural and bilingual background make many highly verbal tests untrustworthy. The two tests chosen for the study were the Chicago Non-verbal Examination and the Cattell Institute for Personality and Ability Testing Culture Free Test. It was assumed that these tests would call attention to students who had good intellectual ability but were below standard in reading and verbal development and had been overlooked because of their lack of verbal fluency.

The two tests were administered to …

An Experiment To Determine If Teacher Preparation In A Small High School Can Be Reduced By Alternating Class Scheduling, John Carl Tuft

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine if by alternating certain classes biennially the number of different teaching preparations could be reduced thus decreasing the teachers' load. The study also attempted to ascertain the effect this type of scheduling had upon the attitudes of teachers and students toward these classes. A further attempt was made to determine if mixing students from two grade levels resulted in the younger student being penalized with respect to his cumulative grade point average.

The significant conclusions that can be drawn from the results follow:

Teachers, generally, thought well of the project and desires …

Relationship Between Self-Concept Discrepancies And The Expression Of Need Achievement In Children, Ian Griggs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study was designed to test the hypothesis that a significant relationship exists between self-concept discrepancies and expressed need for achievement.

A self-concept discrepancy score was obtained and a low and high discrepancy group was isolated.

Expressed need for achievement was measured by the use of the Thematic Apperception Test and scored according to the Atkinson method.

Mean comparisons of need achievement scores of subjects whose discrepancies between actual and ideal self-concept were in the upper or lower one-third of the distribution were found not to be significant at the 5 percent level of confidence.

The Relationship Of Delinquent Types In An Industrial School Setting To Personality-Motivation Profiles, Lester A. Carlson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The author serves as Director of Education of the Utah State Industrial School, a school charged with the responsibility for the custody and treatment of delinquents committed to its care from the juvenile courts of the state. For many years he has been concerned about the personality structure of the children committed to the care of the Industrial School. He became particularly interested in the possibility that there is a definable relationship between types of delinquent acts and personality-motivation profiles. Further motivation was given to this interest when he received an answer to some correspondence from a colleague of Dr. …

Heat Denaturation Of Serum Proteins In Skimmilk And Whey As Measured By The Harland-Ashworth Test, Lynn Verl Ogden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Milk serum proteins have been shown by other workers to be partially protected from heat denaturation by the presence of milk solids (8, 15, 16) and whole caseinate (14). This study revealed that some serum proteins (B-lactoglobulin), as shown by the Harland-Ashworth test (14, 17), were more readily denatured in skimmilk than in rennet whey. A comparison of the heat denaturation rate of serum proteins in whey as opposed to those in whey containing 2.5 percent isoelectric casein was also studied. A striking protection of serum proteins seemed apparent in the presence of isoelectric casein. However, it was learned that …

Ten individuals served as controls and 16 were assigned to the experimental diet. Each of the groups contained an equal number of men and women. The experimental diet provided a ratio of polyunsaturated to saturated fatty acids of approximately one, with the substitution of vegetable oils for animal fats within the normal eating patterns of the participants. The control …

Effects Of Dehydration Processes With Special Reference To Microwave Irradiation On Selected Biochemical And Physical Changes In Apples (Pyrus Malus), Fredoon Shahin Nury

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many innovations have been attempted to shorten drying time or improve dehydration techniques for foods. Despite the recent advances in science and technology the bulk of dried fruit production throughout the world, over 1 1/2 billion tons (dry basis), is prepared by the energy of the sun (Copley and Van Arsdel, 1964). However, other techniques and processes for food dehydration and preservation are occupying more prominent positions in the overall production of dehydrated foods, particularly in the more advanced countries. Economics notwithstanding, it is readily apparent that dehydration as compared to sun-drying offers at least two main advantages. It is …
