Beards And Their Effect On Dimensions Of Self Concept, Douglas C. Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of beards on aspects of self concept were studied. Experimental and control groups were administered measures of "self concept" in pre and post test situations. The experimental group grew beards while the control group continued to shave during the time interim. Results were analyzed using analysis of covariance, but failed to produce any significant differences.

Differences were found, however, in post test results of the within group variability of the experimental group in two areas: feeling reactivity and capacity for intimate contact. This suggests that possibly beards affect people in a wider variety of ways in their sensitivity …

The Development Of A Vocational Interest Inventory Using "Worker-Oriented" Job Elements, Alma F. Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to develop a vocational interest inventory, using the "worker-oriented" job elements of Dr. Ernest J. McCormick and his associates, and to assess the reliability of the resulting instrument.

The interest inventory was prepared, based on 191 of the questions from the Position Analysis Questionnaire, and the test-retest reliability was calculated for a sample of 71 high school students, over a three-week period.

The mean correlation coefficient for the five over-all "job dimension" scores of the interest inventory was .80, and the average item reliability was .54. These coefficients were considered high enough to justify …

Investigation Of One Aspect Of Initiative That Is Subsumed Under Self-Concept And Its Relationship To Performance, John Edmund Genasci

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many children fail to achieve academic success despite an average or above average intellectual capacity, unimpaired motor ability, intact sensory functions, and an absence of major emotional disturbance. These same children have been assigned such descriptive terms as "underachievers" and "children with psycho-neurological disabilities."

It may be more apt to assume that these children who are underachieving and obtaining poor grades do so from lack of feeling of personal initiative and personal control over events in their lives.

This study attempts to investigate initiative as clinically observed and its effect upon tasks requiring an active analytical approach to problem solving. …

1. Is it possible to systematically condition opinion statements in a verbal conditioning situation that resembles a counseling interview?
2. Does the behavior of the operant conditioner during the baseline have any influence on subsequent conditioning of opinion statements in a verbal conditioning situation resembling a counseling interview?
3. Is there a difference in the number of opinion statements emitted in a …

An Evaluation Of The Application Of Survey Research To Public Administration: A Case Study Of The Utah State University Merrill Library, Richard Allan Jenson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Libraries,like many other governmental organizations,have a peculiar difficulty assessing how well they are able to serve their clientele. The reason is that they have no measure of success, such as profits or votes. The only measure is usually vocal communications such as complaints, suggestions, compliments or criticisms. Some of these suggestions are valid, but placing one's judgment on these communications can be very tenuous, and not necessarily representative of the desires of a majority of the clientele.

The purpose of this research was to test the use of survey research as an aid to the public administrator. The intent was …

An Economic Appraisal Of On-Farm Water Management Practices In Developing Countries: A Study Of Summer Rice Production In Guayas Rivers Basin, Ecuador, Thomas L. White

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objective of this study was to examine rice production methods, with special emphasis on irrigation-water management practices used by producers from all levels of management in the Guayas River Basin, Ecuador. To do this, rice producers were divided into four categories on the basis of the level of mechanization of their operation, use of purchased inputs, and the level of investment in irrigation facilities and general management practices. The levels of investment in irrigation facilities ranged from 7,000 to 500 sucres per hectare, and mechanization of production varied from almost total use of machinery for cultivation operations to …

Field Observations On The Biology Of Mimulus Guttatus Dc. In Yellowstone National Park, Wyoming, Barbara L. Rice

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The response of Mimulus guttatus DC. to its unusual thermal habitat in Yellowstone Park is described. Although populations within the park are usually observed in thermal areas, no evidence indicates that they are restricted to thermal soils. The median temperature for soils of natural populations is about 26 C. Populations are distributed in both acidic and basic thermal areas. Success of the species in the thermal soils is facilitated by rapid vegetative growth, allowing fluctuation in population size or position with changes in soil temperature. Water availability is a critical limiting factor in distribution and lack of water tends to …

Polymerization Of Tobacco Mosaic Virus, Fabian Crespo V.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An organic chemical condensing reagent, 1-cyclohexyl-3-(2-morpholinoethyl)-carbodiimide metho-p-toluene sulfonate (CMC) was tested for effectiveness in inducing polymerization of short lengths of tobacco mosaic virus (TMV) nucleoprotein particles isolated from systemically infected Turkish tobacco leaves. It appeared that the chemical induced the formation of phosphodiester linkages between the viral RNA helices in the joining nucleoprotein fragments. Because the polymerization reaction liberates a hydroxyl ion with each joining event the kinetics of the polymerization can be followed with time using a pH meter. The number of hydroxyl ions liberated is equal to the number of polymerizations. Physical evidence of polymerization was obtained by …

Low Temperature Modification Of Cell Ultrastructure In Hardy And Nonhardy Grass Species, Steven L. Kimball

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Studies were conducted to determine the influence of different temperatures (25, 10, 0, or -5 C) upon plant growth and cell ultrastructure, and to determine if physical changes within cells might block growth activities even though individual biochemical processes were potentially active.

Secale cereale L. was found to be most hardy, followed by Cynodon dactylon (L) Pers. and Paspalum notatum Flugge, whose responses were quite similar. Secale grew normally at 25 and 10 C, with reduced activity at 0 C and a slight delay before resuming normal growth when placed at 25 C again. All three species were killed at …

An Electrophysiological Study Of The Oral Plate Sensory Organs Of The Honey Bee (Apis Mellifera L.), Rodney R. Seeley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The oral plate sense organs of the honey bee, Apis mellifera L., have been investigated employing an electrophysiological technique which allows simultaneous stimulation and recording.

The results of the study present evidence that the four bipolar sense cells innervating the sensory papillae on the oral surface of the hypopharynx are chemoreceptors. The sensory papillae respond to cations, glucose, water, and amino acids. Evidence for the absence of a mechanosensory cell is presented. The data concerning the sensory structures agree with the current theories of chemoreception.

Effects Of Dmso And Propham On Mitosis In Root Tips Of Secale Cereale, Max Rosequist

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

DMSO (dimethyl sulfoxide) and propham (isopropyl carbanilate) were investigated to determine their effect singly and in combination on mitoses in rye (Secale cereale) root tip cells. Root tips were prepared for observation by the paraffin and aceto-carmine squash methods. Results showed DMSO caused the following abnormalities: arrested metaphases, multipolar spindles, multinucleate cells, stickiness, shortened chromosomes, and mitotic inhibition. Cells from propham treated root tips exhibited the same abnormalities as those treated with DMSO. In addition, propham treatments resulted in polyploid cells and chromosome granulation. In combination, DMSO and propham caused all the abnormalities mentioned above except polyploidy. In …

Isolation And Characterization Of Autosomal Male Sterile Mutants In Drosophila Melanogaster, Lynn J. Romrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In order to study the genetic control of spermiogenesis, recessive, male-sterile, autosomal mutants of Drosophila melanogaster were induced with ethyl methanesulfonate. A total of 31 mutants were recovered, 15 of which were located on the second chromosome and 16 on the third chromosome. Eight second- and 6 third-chromosome mutants demonstrating sterility in all homozygous males were used for further analysis.

Complementation tests showed that 2 of the 8 second chromosome mutants (and none of the 6 third chromosome mutants) were noncomplementing, indicating that two of the mutants produced were alleles of the same locus. Mapping of the second chromosome mutants …

Ribose 5'-Phosphate Aminotransferase Of Salmonella Typhimurium, Gulamnabi Y. Vahora

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ribose-5 '-phosphate aminotransferase, an alternate first enzyme in the purine de novo pathway, has been purified about 800-fold from Salmonella typhimurium (pur D-55 ). The enzyme is distinct from ribosylpyrophosphate-5'-phosphate amidotransferase (E C 2.4.2.14), has an approximate molecular weight of 229,000, and requires ribose-5'-phosphate, ATP and either ammonium ion, carbamyl phosphate or L-glutamine, to synthesize 5'-phosphoribosylamine (PRA). A coupled assay system, employing a S. typhimurium (pur G-310) extract as the coupling-agent source, was used to measure the enzyme. PRA production in this system was inhibited by higher ribose-5' -phosphate concentrations and longer (over 10 minutes) incubation periods. It …

I. Studies Toward The Synthesis Of Echinodithianic Acid And Ii. The Temperature Dependent Nmr Spectrum Of Methyl N-Acetylsarcosinate, Alan Leroy Love

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Approaches to the preparation of echinodithianic acid (5) from 2,5-dicarbomethoxy-1,4-dithiane (1) were not successful, due to the inability to carboxylate or carboalkoxylate 1 at carbons 2 and 5. Studies toward the synthesis of 5 utilizing methyl 2-acetamidoacrylate (8) have been investigated. The electrophilic addition of sulfur dichloride to 8 yielded bis-(2-acetamido-2-carbo-methoxyvin-1-yl) sulfide, while the addition of thiocyanogen chloride to 8 produced methyl 2-acetamido-3-thiocyanato-acrylate.

As electrophilic additions of unsymmetrical dipolar reagents to methyl 2-acetamidoacrylate (8) are not reported in the literature, the addition of hydrogen bromide to 8 was studied to determine the orientation effect of the acetamido group.

Methyl 2-acetamido-2-bromopropionate …

Ecological Life History Of Rudbeckia Occidentalis Nutt, Juan Arturo Florez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phenological studies of coneflower on aspen range in Northern Utah showed that resumption of growth of mature plants begins at the time of snow melt and the initial or rosette stage is completed between mid-May and mid- June. The rate of growth in this stage is controlled by temperature, being greater at higher mean temperatures. The bolting stage is completed about 1 week after the initiation of stem elongation and the process of capitulum development is begun. Flowering is initiated between late July and mid- August. Cross-pollination is necessary for seed set which is completed by the end of August. …

Selected Physio-Chemical, Microbiological, And Agronomical Studies On The Controlled Atmosphere Storage Of Sugarbeet (Beta Vulgaris) Roots, Vinod V. Karnik

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The post-harvest physiology of sugarbeet (Beta vulgaris) roots was studied during controlled atmosphere (CA) storage at 35° and 50°F. Zero, 3, 6 and 10% carbon dioxide and 5% oxygen concentrations were employed to investigate the most beneficial concentrations of gases. Under the experimental conditions beets were stored successfully for 200 days. The maximum beneficial effects of CA were observed under 6% carbon dioxide and 5% oxygen at 35°F. Regardless of storage temperatures, sucrose retention was highest in the beets stored under CA, compared to conventional refrigeration (CR). Other beneficial effects include less hydrolysis of sucrose to reducing sugars …

Development Of A Whey-Based Lactic Culture Medium Capable Of Bacteriophage Inhibition, Chao Tung Cheng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A whey product has been formulated for use as a lactic starter medium. Phosphate-treated whey medium (PWM) has been shown to support growth of lactic cultures and prevent phage proliferation. Comparisons were made of a commercial phage inhibitory medium (PIM), reconstituted non-fat dry milk (NDM) and PWM. PWM inhibited all phages tested and stimulated starter growth. PWM was not as stimulating as PIM but was better than NDM. Good Cheddar cheese has been made using PWM. PWM is more economical than PIM but NDM is the most economical one if cheese yield is considered.

The Photochemical Reduction Of Octacyanomolybdate(V) Ion In Aqueous Solutions, Gordon W. Gray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The photochemical reactions occurring in aqueous solutions of octacyanomolybdate(V) ion, Mo(CN)₈^3-, during irradiation with light of 365 and 436 nm wavelengths were studied. The quantum yields and reaction products were determined for neutral, unbuffered solutions as well as solutions buffered at pH 4.0, 7.0, and 9.0.

The results of these studies showed that the Mo(CN)₈^3- ion is rapidly reduced by light to a Mo(IV) complex. In neutral or acidic media, the initial photoreduction product was found to be the red heptacyanoaquomolybdate(IV) ion, Mo(CN)₇(H₂O)^3-. Photolysis in basic solution gave the …

The Effect Of Chemical Competition On Thermodynamics Of Bacterial Adsorption, Deorao R. Khairnar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective of this investigation was to study the effect of chemical competition on thermodynamics of bacterial adsorption. This was done using an experimental system consisting of Mendon silt loam soil as the adsorbent, Staphylococcus aureus as a common adsorbate and sodium chloride (NaCl), sodium lauryl sulfate (SLS), and peptone as competitive adsorbates.

The bacterial adsorption on soil both with and without chemical competition followed Langmuir type isotherms. From the equilibrium data, thermodynamic functions such as free energy, ΔF°, enthalpy, ΔH°, and entropy, ΔS°, were calculated. Observed positive ΔH° values indicated that the bacterial uptake in both noncompetitive and competitive …

Cation Exchange And Transport In Soil Columns Undergoing Miscible Displacement, Sung-Ho Lai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A mathematical model was developed to predict the exchange of one cation by another in a soil column undergoing one dimensional cation solution displacement under steady state flow conditions. The model allowed prediction of both the solution and exchanger phase concentration of the cation in question.

The model consists of a material balance equation which is a parabolic type partial differential equation. The assumption was made that equilibrium was reached instantaneously between the cations in the solution phase and the exchanger phase. This assumption reduced the material balance equation to a form that allowed numerical solution providing the data concerning …

A Study Of The Secant Law For Sporadic E, Ruey-Yuan Han

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The secant law is the relationship between the frequencies of a vertically incident wave and an obliquely incident wave that are reflected from the same level (i.e., density) of a stratified ionosphere. This thesis investigates the validity of the secant law applied to sporadic E.

Sporadic E data from two backscatter sounders and one vertical incidence ionosonde located in Japan were studied to test the validity of the secant law. The B-scan photos of the backscatter sounders were searched for E_s patches which were then compared with the sporadic E parameters defined for vertical incidence ionograms.

Finally, two theoretical …
