The Use Of Mental Imagery Among Young Children In The Acquisition Of Piaget's Principles Of Conservation, Richard C. Sweetland

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study attempted to discover some parameters in terms of mental age at which young children, ages five through eight, begin to utilize effectively their mental imagery in the learning process. Using Piaget's principles of conservation as a learning task, subjects were taught in one of two groups: Group one was instructed in conservation concepts by use of concrete example, in which case they were allowed to see, handle and manipulate materials as they underwent transformations. Group two received identical instruction but were called upon to use their mental imagery to visualize the materials undergoing transformations.

Based upon the administration …

Child's Perception Of Parental Attitude And Its Relationship To Academic Achievement And Problem Awareness, Mohammed K. Fazel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was aimed at finding relationships between the triad of academic achievement, child's perception of parental attitude, and his problem awareness. The study was designed with reference to three postulates of phenomenological psychology. (a) The perceptual field of an individual at any moment determines his behavior of the moment. (b) The term phenomenal self is formed by the individual's interaction with others. (c) The basic need of the organism is the maintenance and actualization of the self.

A survey of the literature tended to support the thesis that there was a positive relationship between educational achievement and parental acceptance. …

A Biosystematic Study Of The Genus Aconitum (Ranunculaceae) In The Intermountain Region, Rex Cates

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study dealt with the Intermountain aconites of which the chromosome number of n = 8 was obtained.

The bumblebees, Bombus rufocinctus Cresson, B. appositus Cresson, and B. centralis Cresson, are the major pollinators of the allogamous and autogamous aconites.

Two-dimensional thin layer chromatography of cauline leaf extracts showed that the Intermountain aconites studied here consist of one chemical group.

The overall evidence indicates that the Intermountain aconites consist of one species, Aconitum columbianum Nutt., with two varieties, variety columbianum and variety ochroleucum A. Nels.

Effects Of Two Pathogenically Differing Isolates Of Verticillium Albo-Abrum On Tomato Growth, Leonidas Berry Camp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study was performed using isolates of Verticillium albo-atrum which were reported as varying in their pathogenicities to a susceptible and resistant tomato variety. Also included as objectives in this undertaking were cross-protection and effects of spore density in the inoculum on the development and severity of Verticillium wilt of tomatoes.

After retesting the strains which were reported as pathogenic variants, results suggested that reported variabilities were non-existent in most of the isolates and instead there were only two pathogenic type-categories: (a) strains pathogenic to both resistant and susceptible tomato varieties; and (b) strains pathogenic only to the susceptible variety. …

Biosynthesis Of Piperidine-2-Carboxylic Acid In Fluoride-Necrotic Glycine Max, Susan S. Martin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Synthesis of piperidine-2-carboxylic acid (pipecolic acid) in soybean was studied by infiltration of radioactive carbon labeled precursor and by experiments using enzyme extracts from control and fluoride-fumigated plants.

Pipecolic acid was synthesized from lysine in both control and treated plants. Normal plants, in which pipecolic acid had not been detected by conventional procedures, were capable of synthesizing pipecolic acid. Greater pipecolic acid synthesis was shown in treated plants than in controls, and was attributed to increased enzyme concentration induced by fluoride treatment.

Tests Of Methods That Control Round-Off Error, Dale M. Rasmuson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Methods of controlling round-off error in one-step methods in the numerical solution of ordinary differential equations are compared. A new Algorithm called theoretical cumulative rounding is formulated. Round-off error bounds are obtained for single precision, and theoretical cumulative rounding. Limits of these bounds are obtained as the step length approaches zero. It is shown that the limit of the bound on the round-off error is unbounded for single precision and double precision, is constant for theoretical partial double precision, and is zero for theoretical cumulative rounding.

The limits of round-off bounds are not obtainable in actual practice. The round-off error …

The intent of this thesis is to investigate, develop, and apply techniques to determine the reliability and maintainability of populations of items. These techniques are to be used in determining the total life-time operating costs of the populations so that those items with the lowest life-time costs can be bought. To do this, the author has explored current techniques for determining compliance to some minimum required Mean Time Between Failure (MTBF) in what is referred to as a Phase I testing. After the requirements of Phase I testing have been met, testing may be continued at the option of the …

Algebraic Properties Of Endomorphisms Of Abelian Groups And Rings, Johnnie George Slagle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The main objective of the thesis was to extend the definition of an M-Group to what is called an M-Ring. From this extension a system called an expanded ring follows naturally. To facilitate the development of the expanded ring, chapter I is devoted to developing properties on systems that are not quite rings where many interesting examples are constructed. In chapter II the definition of an M-Ring is given and some of its properties are derived. In chapter III some of the properties of expanded rings are proved, and examples of expanded rings are given to show their existence.

The Value Of A Trout Stream Fishery, Archie Allen Dyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The data analysis indicated that travel distance, user age, and user income level are important determinants of use of trout streams.

These variables were incorporated into regression analysis to develop a use-prediction model.

This use-prediction model was used to determine predicted use levels of sample streams. The predicted use levels combined with travel costs and expenditures on new fishing equipment were used to derive a statistical estimate of the demand schedules for the sample streams.

These statistical demand curves were subjected to consumer surplus procedures to determine the values of the sample streams.

Differential Cross Section For Electron Positron Pair Production From Neutron Proton Scattering, Robert Dalton Wheeler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The differential cross section for a neutron-proton collision forming an electron-positron pair is calculated. The interaction between the neutron and proton is assumed to be pseudo-scalar and that between the proton and the pair electromagnetic. The interaction between the pair and the neutron is assumed negligible.

The methods used to obtain the matrix elements of the process follows that of Möller. The calculation is therefore based on retarded interaction and is relativistic. In obtaining the square of the matrix elements the initial and final polarization states were not considered. The usual projection operator methods were then applied to the intermediate …

A Comparative Study Of Utah's Primary Elections, Owen B. Daw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The advantage of the incumbent in gaining re-nomination and voter participation in primary elections was studied. Six states, Utah, Nevada, New Mexico, Oklahoma, Montana, and Washington were used as examples of different types of primaries during the years compared.

There seemed to be no significant difference in the voter participation between the open and closed primaries. The other factors which influence voting behavior affected voter turnout more than the type of primary did.

The incumbent advantage was slightly greater in the open primary, but not enough to be statistically significant.

The closed primary of 1966 in Utah did affect the …
