Cultivation Of Mushroom Mycelia Using Whey Products As A Growth Substrate, Boyd S. Inglet

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As part of a project designed to utilize common dairy waste products profitably, reconstituted dry whey permeate and delactosed whey were tested as growth substrates for mycelia of the edible mushroom Lentinus edodes. This mushroom was chosen because it is possible to profitably cultivate it due to its popular culinary appeal and perceived medical benefits.

Growth experiments were performed in petri dishes containing either reconstituted dry whey permeate or delactosed whey as a growth substrate, and the measured response was the size of the growing mycelia colony. When reconstituted dry whey permeate was utilized as a growth substrate, the …

Voluntary And Involuntary Weight Change And Risk Of Osteoporotic Hip Fracture In Men And Women Of Utah, Megan Ruth Mcdonough

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Change in body weight is an important determinant of risk of osteoporotic hip fracture in aging adults. Weight loss has been associated with an increased risk of hip fracture and weight gain has been associated with a decreased risk of hip fracture. Weight gain cannot be recommended as appropriate prevention against hip fracture, however, because it is associated with such adverse health outcomes as cardiovascular disease and diabetes, and weight loss is commonly recommended in the treatment of these types of diseases. Clarification of how weight loss is related to risk of hip fracture is needed to resolve this issue. …

The Ability To Taste 6-N-Propylthiouracil (Prop) And Its Relation To A Parent's Emotional Investment In The Infant, Deann Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research on parenting is increasingly being studied from a biological perspective. An understanding of the biological mechanisms leading to individual differences in maternal behaviors can help direct research toward more focused intervention resulting in closer mother-infant attachment relationships, and therefore, positive child outcomes. This research was a preliminary study that tested mothers' ability to taste a harmless chemical, 6-n-propylthiouracil (PROP), in relation to their responses to a questionnaire about the emotional investment they experience towards their infant. Although research attempting to relate these two variables together has not been carried out before, individual studies show potential links between these two. …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship between physicians' perceptions of Mexican American patients at risk for Type 2 diabetes and the subsequent care they provide was studied. Primary care providers responded to questionnaires about their health promotion practices. A 2x2 analysis of variance was used to identify differences in reported treatment of patients that accounted for both ethnicity and risk. Results indicated Hispanic patients received less time with their providers than Caucasian patients regardless of risk for Type 2 diabetes. Both groups received about the same reported care in terms of information gathered for diagnosis, diagnosis made, and treatment regimen prescribed. Data also suggested …

The Effects Of Auditory Stimulation On Academic And Behavior Performance In Children With And Without Attention-Deficit/Hyperactivity Disorder, Penny L. Sneddon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study evaluated the relationship between noise and academic performance and behavior of children with ADHD (n = 15) and without ADHD (n = 18). Children completed math sheets under four noise conditions: no noise, standard classroom noise, classroom noise with verbalizations, and classroom noise with classical music. There were no differences in math performance between the two groups. Children with ADHD exhibited more problem behaviors than children without ADHD. Group-by-condition interactions were not significant. Significant effects were found for noise condition; children completed more math problems and had fewer inappropriate behaviors in the no-noise condition. However, there …

Roles Of Religious Orientation And Health Locus Of Control In An Aging Population, Jennifer A. Fallon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An intrinsic religious orientation has been linked to improved cardiovascular health. Individuals may be protected by their beliefs against anger/hostility, which have been linked to increased cardiovascular reactivity and disease. Health locus of control differentiates between internals, who take responsibility for health, and externals, who attribute responsibility to chance or powerful others. Internal health locus of control has been linked to healthy behaviors, but its relationship to religious orientation is unclear.

Intrinsically held religious beliefs and internally held expectancies for health may, through the mechanism of reactivity, reduce risk for cardiovascular disease. This study explored relationships among health …

School Counselors' Referral Practices Of Children With Internalizing Symptoms, Kelly Hughes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This project proposed to examine school counselors' knowledge of and experiences with internalizing issues in children. The sample included all elementary and middle/secondary school counselors employed in Utah. The measure used in the present study was a questionnaire adapted from a study by Green, Clopton, and Pope. Analyses revealed that few elementary school counselors would meet with a student struggling with internalizing symptoms, but many would meet with the students' teacher(s) and parents. Overall, fewer secondary school counselors endorsed the presented responses as compared to elementary school counselors. More than half of both elementary and secondary school counselors indicated they …

The objectives of this study were to characterize Utah workers who received surgery for CTS in terms of relevant presurgical and outcome variables and to identify presurgical correlates of patient outcomes. Participants were 75 Utah workers' compensation patients who underwent surgery for CTS from 1999-2002 and were at least 6 months postsurgery at time of follow-up. A retrospective cohort design was utilized consisting of a review of presurgical medical records and a postsurgical telephone survey. …

The Use Of Stress Management In Combination With Parent Training: An Intervention Study With Parents Of Preschool Children, Theresa L. Gunderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many preschool children exhibit a number of problematic, acting-out behaviors. Parents of preschoolers exhibiting behavior problems often experience a great deal of stress associated with these problem behaviors. Consistently robust improvements have been found in the use of stress management for adult stress, pain, and medical wellbeing. Likewise, studies have shown parent training decreases the severity of child behavior problems. However, only a few studies have examined effects of parent training on both child behavior and parent stress. Some studies have found that parents who complete parent training also report lowered stress levels commensurate with improvement of child behavior. It …

Developmental Changes In The Structure Of Affect: Is The Tripartite Model Equally Valid For Younger And Older Children?, Bryan B. Bushman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many studies investigating the validity of the Tripartite model of affect in children have been supportive of the model. However, few studies have examined if older and younger children structure affect similarly. The current study used confirmatory factor analytic techniques (SEM) to test the validity of the tripartite model in two developmentally distinct populations of children (third and sixth grade). Confirmatory factor analytic methods examined one-factor, two-factor correlated, and two-factor uncorrelated models. Furthermore, the pattern of correlations between positive affect (PA), negative affect (NA), and dependent measures of anxiety and depression was calculated.

The results indicated the two-factor correlated and …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Migraine headache is a painful and often serious problem in the United States. There are many prophylactic pharmacological and nonpharmacological treatments available for migraine headaches. However, choosing between them can be difficult for individuals and treatment providers alike. The primary literature regarding the effectiveness of pharmacological and nonpharmacological treatments is quite dense. More than 191 primary studies were identified as providing information about the effectiveness of one or more treatments for migraine headaches. Of these, 82 articles were retained for meta-analyses on six prophylactic treatments for migraine: propranolol, flunarizine, divalproex sodium, thermal biofeedback, relaxation treatments, and combined treatments. These results …

Risk Factors For Selected Health-Related Behaviors Among American Indian Adolescents: A Longitudinal Study, Amy Jo Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Suicide and accidents are the leading causes of death among American Indian (AI) adolescents. Engaging in health-compromising behaviors (HCB) is higher among AI youth than among multicultural, national samples of adolescents. These HCBs include: smoking, drinking alcohol, drug use, and delinquency. Studies that identify legitimate predictors of these behaviors among AI adolescents are needed to guide research and interventions.

Primary socialization theory (PST) suggests that peer groups, family, and school are the only areas where adolescents are directly taught to accept or reject deviant or normative behavior. Gateway theory indicates that use of certain drugs by adolescents, such as cigarettes …

An Investigation Of The Impact Of Chld Care Quality On Child Outcomes Using Structural Equation Modeling, Jared Cutler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The quality of a child care setting is believed by many child care researchers to have an impact on the development of children in child care. While a considerable amount of research has been done regarding the impact of child care quality on child outcomes, an examination of literature reviews on the topic reveals that there is a lack of consensus in the field on the question of whether child care quality has a substantial impact on children's development.

The present study assessed the impact child care quality has on child outcomes. A dataset from the NICHD Early Child Care …

Remote Sensing Of Sagebrush Community Structural Patterns Across Scales, Lisa A. Langs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Throughout the Intermountain West there has been a substantial reduction in both the quantity and quality of sagebrush ecosystems. To assist current range management objectives, numerous efforts have been made to classify and map sagebrush communities using remotely sensed data. However, the amount of detail provided by these broad-scale mapping projects is often limited. This research evaluated the ability of a suite of airborne and satellite imagery to detect sagebrush community structural attributes, specifically percent canopy cover, live cover, density, size-vigor, and spatial arrangement of shrubs. Field data was collected at Camp Williams National Guard Training Facility near Bluffdale, Utah, …

Cougar Exploitation Levels In Utah: Implications For Demographic Structure, Metapopulation Dynamics, And Population Recovery, David C. Stoner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Presently, eleven western states and two Canadian provinces utilize sport hunting as the primary mechanism for managing cougar (Puma concolor) populations. However, the impacts of sustained harvest on population dynamics and demographic structure arc not well understood. Additionally, the lack of cost-effective enumeration techniques and strongly conflicting societal values complicate effective management of this species. Given these concerns, the primary goals of this study were (I) to determine the effects of sustained harvest on cougar populations, and (2) estimate the level and extent of cougar harvest statewide.

I monitored cougar populations on Monroe Mountain in south-central Utah, and …

A Longitudinal Analysis Of Socioeconomic Differences In Obesity And Weight Change During The Early Adult Years, Young-Taek Kim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Obesity has reached epidemic proportions in American society. However, not enough attention has been given to weight change by temporal and dynamic detailed social characteristics, controlled for unobserved heterogeneities nested in county and state. Using the National Longitudinal Survey Youth (NLSY79), this study examined weight change and its development into unhealthy conditions like being overweight or obese, in relation to change in social characteristics including life course events. This study also examined the social characteristics of remaining at a normal weight through all time intervals over a 19-year period. Using hierarchical linear multilevel analysis, this study found that changes in …

Intermediate Trainee Perspectives Of Family Therapy Skills, Margo Benson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Marriage and family therapy training involves the development of therapy skills that lead to effective treatment, and the family therapy literature recognizes the importance of skill development in training. The training literature dealing with specific skills most often refers to beginning-level skills and obtains data largely from supervisors and trainers. Intermediate-level skills appear to be overlooked and no apparent attention is given from the perspective of trainees.

This research examined the perspectives of trainees concerning family therapy skills at the intermediate level. Intermediate trainee perspectives were compared with the perspectives of their supervisors. Comparisons were also made with perspectives of …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to examine the attitudes of preservice teachers towards human rights, particularly about human rights related to labor. To assess their attitudes of human rights and unfair labor conditions, two types of presentations, (a) docudrama and discussion, and (b) lecture and discussion, were conducted. The researcher evaluated these teaching methods on their efficacy in creating an awareness of human-rights violations and labor conditions. Additionally, the participants were exposed to two types of invitations to engage in human-rights advocacy.

The study involved elementary preservice teachers and secondary preservice teachers typically at the junior undergraduate level. There …

Snow Avalanche Disturbance In Intermountain Spruce-Fir Forests And Implications For The Spruce Bark Beetle (Coleoptera: Scolytidae), Elizabeth G. Hebertson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spruce beetle outbreaks are the primary biotic disturbance affecting forests in the Intermountain spruce-fir zone. Major snow avalanches can produce large quantities of host material for spruce beetle colonization; however, few studies have examined the influence of avalanche disturbance on outbreak initiation. The purpose of my research was to investigate potential relationships between these two disturbance agents. In the first study, I used dendro-ecological analyses to date major avalanche years on the Wasatch Plateau in south-central Utah, and then determined what climate factors were associated with avalanche occurrence. The results indicated that mean January snowfall was significantly related to the …

This study examined the changes in symptoms of anxiety, depression, and social dysfunction associated with a history of child trauma after adding animal-assisted therapy (AAT) to conventional psychotherapy for adolescents living in a residential treatment facility in northern California. Using a quasiexperimental design, participants were followed over a period of nine weeks, with both groups completing the State-Trait Anxiety Inventory, the Beck Depression Inventory, an abbreviated version of the Beck Depression Inventory, and the Youth Self-Report, and residential staff completing the Youth Outcome Questionnaire at three time points. In addition, the treatment group completed state anxiety and depression assessments before …

Predictors Of Graduation And Rearrest In A Contemporary Juvenile Drug Court Program, Anthony Phillip Tranchita

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research on the efficacy of drug courts for substance-abusing criminal adult offenders has generally found reduced recidivism rates, and both actual and potential cost savings to the public. However, outcome research on juvenile drug courts has been limited. Furthermore, little research has examined variables that may be predictive of outcome in this population. This study reports graduation and rearrest rates for a sample of juvenile drug court participants in Salt Lake City, Utah. Also, this research assessed whether demographics, prior arrest history, attendance at drug education classes, serving detention time, or a preprogram measure of degree of substance abuse (SAS …

A Comparison Of Rational Versus Empirical Methods In The Prediction Of Psychotherapy Outcome, Glen I. Spielmans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several systems have been designed to monitor psychotherapy outcome, in which feedback is generated based on how a client's rate of progress compares to an expected level of progress. Clients who progress at a much lesser rate than the average client are referred to as signal-alarm cases. Recent studies have shown that providing feedback to therapists based on comparing their clients' progress to a set of rational, clinically derived algorithms has enhanced outcomes for clients predicted to show poor treatment outcomes. Should another method of predicting psychotherapy outcome emerge as more accurate than the rational method, this method would likely …

The Reliability And Validity Of The Boatwright-Bracken Child Attention Deficit Scales: Child And Parent Versions, Erica S. Thomas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the psychometric properties of a new measure of attention-deficit/hyperactive disorder (ADHD) symptoms, the Boatwright-Bracken Child Attention Deficit Scale (BCADS), self- and parent-report forms. Parents and children with and without ADHD completed the BCADS to determine the reliability and validity of the BCADS. The BCADS-Child and Parent had high internal consistency reliability. The total sample parent-selfratings were moderately correlated, indicating a typical level of cross informant agreement.

Results indicate that the BCADS differentiates children with ADHD from children without ADHD. Children and parents in the clinical sample reported more symptoms of ADHD than those in the comparison sample. …

Geochemistry Of Ground Water - Surface Water Interactions And Metals Loading Rates In The North Fork Of The American Fork River, Utah, From An Abandoned Silver/Lead Mine, Neil I. Burk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The aqueous geochemistry and hydrology of the North Fork of the American Fork River, its tributaries, and the ground water in the vicinity of the Pacific Mine site were investigated in order to determine what impact ground water entering the North Fork has on toxic metal loads in the river. Toxic metal contamination in the North Fork is great enough that brown and cutthroat trout have absorbed lead, cadmium, and arsenic in their tissues at concentrations that are hazardous to human health if consumed. Ground water that flows through the mine site flows directly through the mine tailings before entering …

Interim Sediment Management Plan For First Dam, Logan River, Thirumurugan Bose

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

Sediment is a serious problem in the management of dams all over the world. In this project an interim sediment management plan for First Dam, on the Logan River in northern Utah, is discussed. The objective of the plan is to control the sediment budget of the reservoir in such a way that other reservoir maintenance activities (e.g., unusual draw downs for structural repairs) will produce minimal downstream environmental impacts on water quality and aquatic resources.

This report presents a detailed literature review of the various sediment management practices used for reservoir sediment control. It also discusses the downstream effects …
