Trade Liberalization: The Impact On Utah's Dairy And Meat Industries, Tyler J. Bowles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Trade liberalization in dairy and meat products is of significant interest for Utah since 75 percent of Utah farm cash receipts are from these two products and both product groups are net U.S. imports. This thesis analyzes the impact that trade liberalization in dairy and meat products would have on Utah's dairy and meat industries and Utah's general economy.

A model based upon the current level of imports and exports, the price elasticity of import demand, and the tariff equivalent of import restrictions is used to estimate the production changes in Utah's dairy and meat industries that would result from …

It was able to detect …

A Model For Estimating Available Iron From Total Nutrient Intakes, Ann Marie Black

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Factors which affect iron bioavailability have been repeatedly and extensively investigated. A model, derived from these studies, has been developed for estimating available iron from meal data. However, many dietary surveys report only average daily intakes of iron, and do not report the iron present in single meals. No model to estimate available iron from daily iron intake has been presented in the literature.

Dietary questionnaires were kept for two nonconsecutive weekdays by 355 male and 382 female Utah school children, mean age 7.5 years, assisted by their parents, and recorded by household measure. Data, first recorded as meals eaten, …

The Stability And Predictive Validity Of The Bayley Scales Of Infant Development: A Meta-Analysis, Gary A. Goodrich

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Bayley Scales of Infant Development (Bayley, 1969) is the most widely used infant assessment instrument in the United States. Reasons for its widespread use include research into the nature and development of intelligence, studies of intervention efficacy, and treatment and placement of handicapped infants.

To this date, the stability and predictive validity of the Bayley scales have not been well established. According to Webster and Bates, "There remains a serious lack of research examining the stability of all general intelligence measures over extended intervals of time" (1977, p. 5). Anastasi (1976) suggests that tests like the Bayley are particularly …

Martin Harris In Cache Valley - Events And Influence, Scott R. Shelton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The well-known Mormon historical figure, Martin Harris, spent the last five years of his life in Cache Valley, Utah. Most of the research done to this point on this man, who claimed to have seen angels and heard the voice of God, has been on the early years of LDS Church history during which Harris was intimately involved with the coming forth of The Book of Mormon. Little has been done on his years in Cache Valley, except for collections of affidavits concerning his testimony.

This study gives a brief overview of Harris's first eighty-seven years, his journey to …

The Classroom Modification Of Children's Gender Stereotyping Of Careers, Paul Vance Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research tested the use of non-sexist occupational modules of teaching activities and toys for preschool, second grade and fourth grade classes. In addition to brief descriptions of biological, cognitive development and social learning theories of gender role development, the literature review also focuses on factors which contribute to gender stereotyping in schools: teachers, teacher training, toys, teaching materials and activities. Several hypotheses were tested comparing project members as presenters of modules versus module use by regular classroom teachers and a module-free control group in each grade. Also, second graders were tested in third grade to assess persistence of module …

Diagenesis And Water Chemistry Of The Woodbine Group In The East Texas Basin, Helmuth Victor Wuerch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Petrographic and SEM study of flu vial-deltaic sections of the Woodbine Group in the East Texas Basin indicates that authigenic mineral suites are controlled, in part, by the presence of organic-rich matrix.

During early, precompaction diagenesis, organic matter supplied the metabolic fuel required by sulfate-reducing bacteria to reduce sulfate in depositional waters ultimately to pyrite. With burial the sulfate supply was ultimately exhausted, and bicarbonate activity thereafter controlled the precipitation of siderite and Fe-calcite.

Matrix material supplied the components and reaction sites for the most import ant porosity-occluding reaction: kaolinite --> Fe,M g chlorite. Matrix physically inhibited the growth of …

Petrology Of The Late Proterozoic(?) - Early Cambrian Arumbera Sandstone And The Late Proterozoic Quandong Conglomerate, East-Central Amadeus Basin, Central Australia, Johnnie O. Phillips

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Throughout the James Ranges and Gardiner Range the Arumbera Sandstone forms prominent strike ridges with distinctive dark reddish slopes and pale red to orange-white cliffs. Because of their lithologic and stratigraphic similarities, the names Eninta and ''Quandong" for these units should be suppressed in favor of the name of Arumbera Sandstone, which has precedence. The stratigraphic and lithologic differences observed between the Quandong Conglomerate in the type locality and the Arumbera Sandstone in the study area suggest that these units are not equivalent. Similarites with the Areyonga Formation suggest the Quandong Conglomerate could be part of the Areyonga Formation.

Lithofacies …

Boron Composition Of Alfalfa In Utah As Related To Soils And Irrigation Waters, Robert N. Radtke Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Eighteen field plots at 15 locations were selected throughout the state to evaluate the status of the boron content in irrigation waters, soils, and alfalfa (Medicago sativa) plant tissue under irrigated conditions.

No boron deficiency symptoms were observed in any of the alfalfa plants at any of these locations, nor were any of the plant tissue boron levels inadequate. Only two locations were found in which the alfalfa plants exibited toxicity symptoms. These locations were along the Indian and Antelope Creeks in Duchesne County which contain high boron levels in the water. All the alfalfa and soil tested …

Natural Cheese From Prefermented Whole Milk Retentate, Charles Gordon Brown

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A new method for manufacture of natural cheese was developed using 5X ultrafiltered whole milk retentate. The retentate was prefermented to pH 5.0-5.2 before curd formation to simplify the cheese making process. It was demonstrated that the process can be made commercially feasible.

Ultrafiltration and diafiltration of whole milk were done so that the desired level of residual lactose was left in the retentate. Retentate was inoculated with lactic starter culture and incubated (prefermented) until all lactose was converted to lactic acid. The final pH stabilized at about 5.0-5.2; the desired pH of the cheese curd. Incubation at 25°C allowed …

Detection Of Abnormal Milk With Impedance Microbiology Instrumentation, Fahad Ali Abdulghany Khayat

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mastitic milk was detected by obtaining conductance measurements using an impedance microbiology Bactometer® 120 SC instruments. Conductance readings taken after 30 min at 25'C separated normal and abnormal milks when readings differed by more than 3% from the variance among instrument module wells. Samples blended from four quarters of a cow indicated milk from one quarter was abnormal if the salt level in the abnormal quarter raised the blend conductivity above that of normal samples and variance among the wells. Either solid or liquid substrates that contained bacterial stimulants could be used to accelerate bacterial acid production or to reduce …

More specifically the question of whether the length of utterances, number of emotional words used and statements about self by the subjects differed between groups using the Color Book and interviews without art materials.

Subjects were forty grade school age children attending public schools. Twenty had previously been classified as behaviorally disordered and the other twenty had no such classification. Half …

The Mmpi As A Predictor Of Post-Traumatic Stress Disorder Among Vietnam Veterans, Susan Rogers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine whether the Minnesota Multiphasic Personality Inventory (MMPI) could be used to discriminate between Vietnam veterans with Post-Traumatic Stress Disorder and those with other mental disorders. Scores on the 13 validity and clinical scales of the MMPI were used as predictor variables in two discriminant analyses. The first of these was performed in replication of studies in which cases of substance-abuse disorder were eliminated from the non-PTSD comparison group. Substance- abuse cases were included in the second discrimination. The results indicated that while the MMPI can be used to discriminate PTSD from non-PTSD …

Demand Characteristics In The Hypnotic Elicitation Of Multiple Ego States, Laura M. Sturgis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Hypnotic elicitation of multiple ego states was explored using Hilgard's "hidden observer" paradigm. Twenty subjects in two groups: hypnosis and simulation were utilized to examine the impact of experimental demand characteristics on the production of multiple ego states. Self-report and hypnotist-report measures were obtained in a test-retest design. Multiple t-tests and chi-square analyses were computed with significant differences on key multiple ego state items found between groups. Results demonstrated retest reliability, but not inter-rater reliability of this dissociative phenomena, since hypnotists failed to discriminate real from "faked" hypnotic involvement. Exploration of multiple ego states using non-hypnotic control conditions and multiple …

Contextual Control Of Stimulus Equivalence With Preschool Children, M. Regina Green

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research asked whether a contextual stimulus in a visual conditional discrimination task controlled membership in classes of stimuli related hierarchically. Six experiments with nonreading preschool children posed the following question:

Does a stimulus juxtaposed with a conditional discrimination task control relations among the stimuli involved in the task? In Experiments I and II, printed instance or concept words were juxtaposed with conditional discrimination tasks involving symbols. Results for eight of nine children demonstrated neither conditional nor equivalence relations between words and symbols.

Would conditional discrimination training establish classes of visual stimuli composed of selectively nonequivalent subsets? In Experiment III, …

Person-Environment Interaction Psychological Strain And Delinquency: A Longitudinal Test Of The Theory, Mahmood Gazi-Tabatabaie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utilizing longitudinal panel data from Youth In Transition Project, the Person-Environment fit (P-E Fit) theory and its specific application to the area of delinquency and aggression was investigated longitudinally. Analysis of Covariance Structure Technique (LISREL) was used to address the issues of multi-dimensionality, stability, measurement of total P-E fit and to test the proposed delinquency model. The relationships between P-E fit, psychological strain, and delinquency were tested both cross-sectionally and longitudinally. The student sub-group (those respondents who stayed in school after high school) and the working sub-group (those who went to work after high school) were tested separately. P-E fit …

The Vertical Distribution Of Salts In A Soil Profile During The Drainage Process, Adel Taha Yassin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to develop a model to predict water extraction patterns and therefore salt distribution patterns in a one dimensional homogeneous soil profile for a specified root distribution.

Water extraction was simulated as a function of the total potential and the root density at any level of the profile.

Salt redistribution caused by irrigation was simulated by assuming a partial and proportional displacement of the water in each soil layer.

A computer program was written for the model in Fortran language and implemented on the Vax. To evaluate the performance of the model, test studies were …

Depression and perceptions of physical health were the two aspects of adjustment selected for study. Several variables which current literature suggests may mediate grief adjustment were examined for their potential relationship to bereavement outcome. These were gender, level of grief, anticipatory grief and social network. The possible relationship between depression and perceptions of physical health was also examined for.

Subjects were 75 men and women, age 55 and over, who were recently widowed, and 29 …

The Surficial Geology And Neotectonics Of Hansel Valley, Box Elder County, Utah, Robert M. Robison

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Hansel Valley, located at the north end of the Great Salt Lake in Box Elder County, Utah, has exposures of the lacustrine sediments of the Little Valley, Bonneville, and Gilbert lake cycles. A 1:50,000 scale map was constructed of the surface geology. Although no trenches were dug for this study, about 240m of logs were compiled in an arroyo in lake bottom sediments. Sediments from at least three lake cycles were found in this gully: 1) compact bottom deposits from the Little Valley cycle; 2) bottom sediments from an intermediate cycle (the Hansel Valley cycle); and 3) beach gravel and …

Contingent Valuation Of Early Intervention Programs For Handicapped Children, Colette M. Escobar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Early intervention programs for handicapped preschool children may have long-term implications for the children and their families. Economic evaluations of these programs have been conducted to measure costs and benefits, but parental willingness-to-pay has been overlooked in these analyses. Parental willingness-to-pay, as a measure of consumer surplus, could complete the measure of benefits and provide both policymakers and practitioners with useful information for decision-making. In this study, the implications of eliciting willingness-to-pay responses for an early intervention program for handicapped preschoolers are discussed. A survey technique, known as the contingent valuation method (CVM), is applied to program to empirically estimate …

Land Use Controls As An Influence On Surface Water Quality In Cache County, Utah, Jerry E. Sempek

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The purpose of this thesis is to identify land use planning strategies which are most appropriate for the mitigation of nonpoint surface water pollution problems in Cache County, Utah. This work expands on an initial planning effort by the County intended to address these pollution problems. Unfortunately, that effort resulted in the adoption of an ordinance which falls short of ensuring surface water protection.

Planning strategies designed to protect wetlands and provide water resource protection have been proposed and implemented in other regions of the United States. A sample of these programs was selected and their similarities and differences were …

Investigation Of Host Selection By Mountain Pine Beetle (Dendroctonus Ponderosae) Hopk. In Lodgepole Pine (Pinus Contorta) Dougl., Thomas James Eager

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lodgepole pines Pinus contorta (Douglas) were treated by girdling to assess the response by an endemic population of mountain pine beetle Dendroctonus ponderosae (Hopkins) (Coleoptera: Scolytidae). Capture in 'sticky traps' indicated that the beetles were attracted while in flight towards the wounded trees. A significant difference in the landing rates of bark beetles between the treated and untreated trees indicated that the beetles were able to distinguish wounded from non-wounded trees while still in flight. Pressure chamber readings demonstrated that water stress developed in the girded trees when compared to the non-girdled trees.

Impact Of The Western Spruce Budworm On Buds, Developing Cones And Seeds Of Douglas-Fir In The Intermountain Region, Charles Joseph Frank

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The western spruce budworm, Choristoneura occidentalis Freeman (Lepidoptera: Tortricidae), is a serious defoliator of conifers in the western U.S. and western Canada. In 1985 epidemic levels of the budworm caused average tree defoliation in west-central Idaho to increase to 83%, up substantially from the 35% average tree defoliation of 1984. Associated with this increase in defoliation was a change in the relative stand defolation ranking between the two years. found to damage all types and In 1985 the budworm was developmental stages of reproductive structures of Douglas- fir, including: seedcone buds, pollen-cones buds, maturing cones, and seeds. Differential selection of …
