A Description Of Change In School Expenditures In The San Juan School District From 1951 To 1965 And An Analysis Of Student Achievement During The Same Period, Kenneth B. Maughan

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 …

A Logical Classification Of And Recommendations For The Utah Education Law, Thurman M. White

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As our society becomes more complex, it follows that the laws governing this society become more numerous and more complicated. Problems arise relative to local, state, and federal control, necessitating further interpretation and ultimately new laws. The areas where legal confusion is most obvious are those subject to control by all levels of government: local, state, and federal.

The Ecology Of The Black-Bellied Tree Duck In Southern Texas, Eric George Bolen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The black-bellied tree duck (Dendracygna autumnalis) is one of eight tree ducks (whistling ducks) in the genus Dendracygna. This group shares enough characteristics--reticulated tarsus and symmetrical syrinx structure, among others--with the swans and geese to warrant a common subfamily, Anserinae of the waterfowl family Anatidae. DeIacour and Mayr (1945) make a tribal distinction, however, between the tree ducks (Dendracygnini) and the swans and geese (Anserini) based, in part, an differences in size, vertebrae number, and downy plumage. These same authors remark that the tree ducks are the least known of the waterfowl largely because there are no …

Brisket Disease: Elemental And Oxalate Contents Of Cattle Forages On Two Utah Cattle Allotments, Raga Hafez I. Abaza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It was hypothesized that the hypocalcemia, hyperphosphoremia, hyperkalemia and the mild hypochromic microcytic anemia which existed in cattle afflicted with brisket disease could be due, at least in part, to nutritional disturbances. A chemical composition study was made of seven monocotyledonous plant species that comprise a major part of the diet and nine dicotyledonous plant species consumed by cattle and known or suspected of being poisonous. The plants analyzed were collected from two cattle grazing allotments, 7-mile and UM, in the Fishlake District, Fishlake National Forest, Utah, where brisket disease incidence is high. In each species the percentages on dry …

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

The primary objective of this study was to establish a production function for alfalfa grown in the Sevier Valley using farm survey data. A secondary objective was to point out the analytical difficulties in establishing a production function for alfalfa.

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. …

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 …

An Investigation Of Methods For Estimating Marginal Values Of Irrigation Water, Richard L. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Marginal values of water used in irrigation are needed if water is to be optimally allocated among alternative uses. Cobb-Douglas production function analysis and linear programming methods were studied in this investigation to find their fruit-fulness in predicting these marginal values. The theoretical properties of both methods indicate that they are conceptually capable of yielding valid marginal value estimates for irrigation water.

Further investigation of the two methods was carried out as an empirical test in the Milford area of Utah. Marginal values of water used for irrigation in that area were estimated by both procedures. Although inviolable criteria for …

Guarded And Unguarded Responses To Sentence Completion Tests Among Normal Adolescents And Juvenile Delinquents, Mohammed K. Fazel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was designed to test the responses of a group of juvenile delinquests and a group of normal adolescents to a sentence completion test. The test used was a modified form of Sack's Sentence Completion test in two forms--form A, first person stems and form B, third person stems. The hypothesis to be tested were (1) people project more in the third person, (2) the normal projects more, and (3) there would be no difference in projection on neutral items. The results bear out the three hypothesis. The sex scale, however, was an exception. This may be due to …

Evaporation And Evapotransipration In Venezuela, Hidalgo Guillén Echeverría

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Equations and tables for estimating Fuess evaporation from climatological data were developed. Ten years of average records from 22 stations in Venezuela were analyzed in order to develop the equations.

Ev = K C_RC_TC_WC_HC_DTC_SC_M
Pan evaporation was computed using the Christiansen, Mathison, Blaney-Criddle, Hargreaves, Penman, and Kohler formulas. The computed pan evaporation from these formulas, measured Fuess evaporation, and …

Fluoroorganic Compounds In Relation To Hydrogen Fluoride Exposures In Leaves Of Glycine Max Merr., Julie Ye-O Cheng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soybean plants were fumigated in HF and the organic acid-fractions of the leaf extracts were compared to those of the leaf extracts from soybean plants grown in nutrient solution containing fluoroacetate. The extracts from both treatments contained fluoroorganic compounds that were chromatographically similar to fluoroacetate and fluorocitrate.

The fluorocitrate separated from HF fumigated leaves was found to inhibit aconitase prepared from pig-heart. This inhibition was similar to that caused by commercial fluorocitrate and the fluorocitrate synthesized using guinea-pig kidney. The aconitase from soybean leaves was found to be sensitive to fluorocitrate as the aconitase that isolated from pig-heart. Inorganic fluoride …

Histochemical Investigations On The Effects Of Fluoride On Oxidative Enzymes From Pelargonium Zonale And Allium Cepa, Bachettira Wthappa Poovaiah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of fluoride fumigation on Pelargonium zonale leaves and also sodium fluoride infiltration of leaf sections and Allium cepa roots were studied in vivo.

Anatomical studies of fluoride-injured leaves showed a total collapse of the margin of the injured leaf. In injured regions the upper epidermal cells were normal and were the last to be destroyed. Detailed study of the vascular region of leaves near the injured area and also petioles from severely injured leaves showed clogging of xylem vessels by tyloses. Clogging of sieve tubes occurred, presumably, due to deposition of callose substance on sieve plates of …

Karyotype Analysis As An Index Of Radiosensitivity Of A Grass Hybrid, David R. Braegger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Large differences exist between plant species in their response to ionizing radiation. The factors involved in radiosensitivities are complex and not well understood. The best criterion, so far, in studies on the acute lethal level of radiation for plant species is the average interphase chromosome volume (Sparrow et al. 1963). There are also close relationships that exist between DNA content, nuclear volume, total chromosome volume and radiosensitivity (Bowen, 1962; Sparrow et al. 1963; Sparrow et al. 1965). These investigators have observed in a series of species that an increase in nuclear volume is often accompanied by an increase in DNA …

Until 1864 the region was utilized for non-mining activities. By the 1870's, mining "boomed" and various settlements were established in the canyon. The most famous of these was …

The "Starvation Effect" And Tryptophan Pyrrolase Activity In The Vermilion Mutant Of Drosophila, Ernest E. Shelton Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The enzyme tryptophan pyrrolase is controlled by the vermilion locus in Drosophila melanogaster and is normally lacking in the vermilion mutants. During this investigation it has been demonstrated that v¹;bw flies have tryptophan pyrrolase activity when grown under near starvation conditions.

During development of the fly there is a peak of enzyme activity in the early third instar soon after the transfer to starvation medium. A second peak of enzyme activity occurs during the pupal stage. The activity in v¹;bw pupae is about 15% of the activity found in cn bw adults.

In v …

Design Optimization Using Model Estimation Programming, Richard Kay Brimhall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Model estimation programming provides a method for obtaining extreme solutions subject to constraints. Functions which are continuous with continuous first and second derivatives in the neighborhood of the solution are approximated using quadratic polynomials (termed estimating functions) derived from computed or experimental data points. Using the estimating functions, an approximation problem is solved by a numerical adaptation of the method of Lagrange. The method is not limited by the concavity of the objective function.

Beginning with an initial array of data observations, an initial approximate solution is obtained. Using this approximate solution as a new datum point, the coefficients for …

An Exposition On Bayesian Inference, John Laffoon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Bayesian approach to probability and statistics is described, a brief history of Bayesianism is related, differences between Bayesian and Frequentist schools of statistics are defined, protential applications are investigated, and a literature survey is presented in the form of a machine-sort card file.

Bayesian thought is increasing in favor among statisticians because of its ability to attack problems that are unassailable from the Frequentist approach. It should become more popular among practitioners because of the flexibility it allows experimenters and the ease with which prior knowledge can be combined with experimental data.

A Follow-Up Study Of The High School Graduates From The Cache County School District From 1956 Thru 1965, Dennis Howard Hancock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since any education institution is judged in terms of what it contributes to its students and to the welfare of society, it is almost certain that a follow-up study of the students will provide information that could aid in evaluating and improving the school's guidance and instructional programs; identifying needs and problems of graduates for future service by the school; and bringing the school and community closer together by promoting common understanding.

Follow-up studies are considered one of the most reliable methods of determining the effectiveness of educational programs. It is believed that this follow-up study can provide the Cache …

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 …

A Method For Quantifying The Effects Of Apomorphine Upon The Gnawing Syndrome Of The Rat, Paul Robinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Various methods were tried in an attempt to obtain a technique for quantifying the gnawing effects of apomorphine on rats. A technique using a restraining tube was developed.

Under a 2 milligram per kilogram intraperitoneal injection of apomorphine, four female Long Evans hooded rats were placed on continuous and fixed reinforcement schedules using a gnawable pine block. Subjects would learn to turn their heads away from the gnawable object in order to obtain 15 seconds of gnawing time. The rate of response increased from less than one response in 5 minutes to over 3 responses per minute in 10 one-half …

The Effects Of Response Set On The Structured-Objective Rorschach Test, Richard Y. Moody

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The normal forced-choice Structured-Objective Rorschach Test (SORT) and a modified free-choice SORT were administered to sixty high school students to determine the effects of response set (e.g. social desirability). The results were inconclusive. The following trends, however, were observed: (1) The free-choice modification was more resistant to response set distortion than the normal forced-choice SORT. (2) The free-choice administration showed greater flexibility in enhancement and resistance to social desirability. (3) There was little sex difference in factor scores with respect to choice administration. Females, however, gave more responses than males on the free-choice SORT.
