The Influence Of Teaching Experience Upon School Counselors, John Whorton Allen May 1969

The Influence Of Teaching Experience Upon School Counselors, John Whorton Allen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The increased demand for more school counselors since World War II raised many questions concerning their preparation and training. One of the most controversial topics has been that of requiring teaching experience as a prerequisite for counselor certification. We find ourselves in a milieu of controversy in which some advocates are proposing that teaching experience can handicap the counselor in his effectiveness while others are saying that teaching experience is a vital prerequisite for counselor effectiveness.


Microenvironmental Effects Of Erosion Control Treatments On Seedling Survival In A Southeastern Utah Salt Desert Area, Ross W. Wein May 1969

Microenvironmental Effects Of Erosion Control Treatments On Seedling Survival In A Southeastern Utah Salt Desert Area, Ross W. Wein

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of the microclimate of erosion control treatments was carried out in two habitat types in a semiarid southeastern Utah, salt desert shrub area. The soils are highly eroded Mancos shale and support a low density of salt desert shrub species which offers little protection against high intensity summer convectional rainstorms.

Gully plugs and contour furrows had been installed by the Bureaus of Reclamation and Land Management to prevent runoff of soil laden water which results from these summer rainfalls. Formerly this sediment was carried to the Colorado River and deposited in Lake Powell.

The purpose to t he …

One drink was fortified with sufficient ascorbic acid to contain considerably more vitamin than was found in pure orange juice.

The ascorbic acid values of different forms of orange drinks and pure orange juices were compared. Except for one brand, …


Study Of Sheltered Evaporation In Colombia, Guillermo Pardo-Bonilla May 1968

Study Of Sheltered Evaporation In Colombia, Guillermo Pardo-Bonilla

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Equations, tables, and graphs for estimating evaporation from sheltered evaporimeters were developed, based on data from 20 stations in Colombia.

Computer programs and plottings were the basic tools to work out the equations. The form of the simplified final equation is

Ev = kCVPDCT

in which

    • Ev is the evaporation in millimeters per day
    • K is a constant
    • CVPD is the vapor pressure deficit coefficient
    • CT is the temperature coefficient

Statistical parameters were determined to compare the measured evaporation with the Christiansen-Guillen formula and the newly developed formulas.

Ninety-eight percent of all waterfowl observed were below 10,000 feet.

Waterfowl numbers were highest during migratory periods and lowest in the breeding season.

Adult waterfowl were observed most often on natural water areas and beaver ponds greater than one acre.

Water areas at lower elevations had high indices of aquatic invertebrates and contained …


Effect Of Gibberellic Acid And Chilling On Nucleic Acids During Germination Of Dormant Peach Seed, Yuh-Nan Lin May 1968

Effect Of Gibberellic Acid And Chilling On Nucleic Acids During Germination Of Dormant Peach Seed, Yuh-Nan Lin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of nucleic acid changes influenced by gibberellic acid and chilling treatments in peach seed was performed in an attempt to reach a better understanding of the mechanism involved in breaking seed dormancy.

Gibberellic acid and the chilling treatment increased the RNA content. These two treatments which break dormancy also increased RNA, suggesting a similar mechanism involving RNA. Chilled seeds contained more RNA than did the gibberellic acid treated seeds.

DNA content remained unchanged regardless of treatment.

Dry seed had a greater ribonuclease activity than with soaked seeds. Enzyme changes did not correlate well with the RNA content in …

A study of the adaptive changes of some enzyme activities to the dietary protein intake was made in the liver, kidney, and pancreas of rats and serum of humans.

The rats fed the 40 per cent casein diet had a higher rate of weight gain and the weights of the liver and kidney were higher than in the rats fed the 10 per cent casein diet.

Three enzymes involved in the elimination of excess nitrogen from the body were found to show a similar response to increased dietary protein intake. These enzymes were: D-amino acid oxidase in the kidneys, arginase …


The Use Of Mental Imagery Among Young Children In The Acquisition Of Piaget's Principles Of Conservation, Richard C. Sweetland May 1968

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 …

A Study Of Life Crisis Magnitude Of Psychiatric Patients And A Non-Therapy Group, Helen B. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A group of hospitalized psychiatric patients and a randomly selected non-therapy group responded to the Schedule of Recent Experiences questionniare. In order to determine the magnitude of life change events for the two groups, Life Change Unit totals were derived for the years 1966 and 1967.

To test the hypothesis that patients in psychiatric treatment have experienced a quantitatively significant greater amount of life change than a group of non-therapy subjects, an analysis of variance was used to determine whether there were significant differences between the scores for the two groups.

For the year 1966, no significant difference was found …


A Biosystematic Study Of The Genus Aconitum (Ranunculaceae) In The Intermountain Region, Rex Cates May 1968

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.


A Description Of The Planarian Phagocata Crenophila, New Species, From Utah, Jerry H. Carpenter May 1968

A Description Of The Planarian Phagocata Crenophila, New Species, From Utah, Jerry H. Carpenter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A new species of planaria in the genus Phagocata was found in several springs and spring-fed streams in Logan Canyon, Cache County, Utah. This species was named Phagocata crenophila because it greatly prefers to live in springs and it seems to be adapted behaviorally to this type of habitat. Serial sections and whole mounts were made by standard methods in order to study the anatomical features which are necessary for identification of planarians. The distinguishing features of this species are the following: testes ventral and extending from near the brain to near the posterior end, ejaculatory duct opening ventrally from …

The effect of temperature and inoculum density on the incidence of disease on radish caused by Rhizoctonia solani Kühn was studied. The fungus attacks radish at one or more stages during host development and causes pre- and pose-emergence damping-off, root rot, and storage-organ decay. The isolate of the fungus used in the study was obtained from infected radishes grown in Salt Lake County, Utah.

To determine the effect of temperature on the pathogenicity of R. solani on radish, soil temperatures of 15, 20, 25, and 30 C were used. Varying inoculum densities of 1360, 816, 408, 136, and 0 grams …


Biosynthesis Of Piperidine-2-Carboxylic Acid In Fluoride-Necrotic Glycine Max, Susan S. Martin May 1968

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.

Factors Associated With The Penetration And Colonization Of Tomatoes By Verticillium Dahliae, Terry Dee Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiments have demonstrated that Verticillium dahliae is capable of direct cortical penetration of roots and of subsequent distribution throughout plants of both resistant (Loran Blood) and susceptible (Meteor) varieties of tomato. Plants were inoculated by the root dip method and planted in sterile soil. After one week the fungus was isolated from the upper portions of both the susceptible and resistant varieties as indicated by growth petiole sections plated on PDA. The distribution of the fungus in the resistant plants was irregular, but in susceptible plants the fungus was isolated regularly from all petiole sections. In experiments using disposable growth …


Effects Of Two Pathogenically Differing Isolates Of Verticillium Albo-Abrum On Tomato Growth, Leonidas Berry Camp May 1968

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. …


Development And Control Of Licking Behavior In The Guinea Pig (Cavia Porcellus), Jack R. Alvord May 1968

Development And Control Of Licking Behavior In The Guinea Pig (Cavia Porcellus), Jack R. Alvord

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Four non-licking guinea pigs were reinforced with water for successive approximations to licking an operandum feeder. Once all subjects had obtained their total liquid intake for a three-week period by licking, an optimum deprivation schedule was determined.

Fixed ratio and variable interval schedules were found to affect licking behavior of the guinea pig in a similar way as with the rat, mean lick rate of guinea pigs being slightly lower than that of the rat. Precise control over the onset and offset of licking was demonstrated through discrimination training.


The Relationship Of Occupational Choice To Ego Identity And Self-Concepts, Norman D. Bell May 1968

The Relationship Of Occupational Choice To Ego Identity And Self-Concepts, Norman D. Bell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study attempted to investigate the relationship of occupational choice to ego identity achievement, to self-concept, and to academic achievement, as these are related to Eric Erikson's contention that is adolescents' inability to settle on an occupational choice which disturbs them and results in a sense of identity diffusion (lack of solidified ideas of self, goals for life, and a need to seek external supports).

The sample consisted of 320 senior high school boys in the tenth, eleventh, and twelfth grades.

Variables considered included: level of vocational commitment; ego identity; self-regard, i.e., self-concept, self-acceptance, ideal self and adjustment (sum of …
