Influence Of Fall Grazing By Sheep On Plant Productivity, Shrub Age Class Structure And Herbaceous Species Diversity In Sagebrush Steppe, Ryan Duncan Woodland

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Traditional chemical and mechanical treatments of Wyoming Big Sagebrush (Artemisia tridentata ssp. wyomingensis) are costly and have typically focused solely on increasing forage for livestock production. Managing these systems biologically with grazing can potentially reduce costs and increase both biodiversity and understory production as well as rejuvenate Wyoming Big Sagebrush (ARTRWY). This experiment was conducted on Deseret Land and Livestock Ranch in northern Utah in October 2003. One hundred and twenty sheep (dry ewes) grazed 3, 60m x 40m plots (40 sheep plot^-1). Sheep were provided a protein-energy supplement to facilitate use of the secondary metabolites …

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 …

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 …

Power Distance Perceptions In Post-Soviet Russia: Understanding The Workplace Environment, Olga Kamenchuk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The modem business economy is characterized by increased collaboration among different organizations across nation al boundaries. Post-Soviet Russia is one of the regions that is witnessing rapid economic growth and development of international business relations. Because of the challenges in intercultural communication the current study focuses on the problem of power distance, specifically in the workplace (in post-Soviet Russia).

A phenomenological perspective, based on qualitative methodology, guided this research into the meaning of power experiences for individuals. Symbolic interactionism was used as a research paradigm of the study to view humans as active participants of the workplace, who engage in …

Predictors Of Outcome Of Surgery For Carpal Tunnel Syndrome, Clayton T. Manning

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wrist surgery is a common method for treating carpal tunnel syndrome (CTS) although few studies have examined patient outcomes or predictive correlates of such procedures. 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. …

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 …

Pharmacological And Behavioral Treatments For Migraine Headaches: A Meta-Analytic Review, Kristi Lowe Stewart

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 …

Changes In Child Symptomatology Associated With Animal-Assisted Therapy, Catherine C. Woolley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

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 …

Rubella Immune Status Of Pregnant And Non-Pregnant Women In Istanbul, Turkey, Sebahat Seker, M. Fatih Abasiyanik, Barik A. Salih

Saudi Medical Journal

OBJECTIVE: Rubella immunization rates are not optimal and infections during pregnancy still occur since many countries incorporate no rubella vaccine in their national immunization program. The evaluation of immunity to rubella virus relies on the presence of specific antibodies. This study was undertaken to determine in a cross-sectional survey whether rubella virus circulation in the Istanbul city, induces detectable immunoglobulin G (IgG) antibodies with a protective level, in a random group of pregnant and non-pregnant women. METHODS: One hundred and sixty women of 20-41-years of age (average 24-years) were grouped as follows: 1. Forty-eight married women. Among these were 41 …

Exploring The Factors That Promote Risk Taking, Innovativeness, And Proactiveness Among Managers And Employees: The Influence Of Trust, Motivational, And Enabling Mechanisms, Michael G. Stull

Student Scholarship

With the current competitive challenges facing for-profit and nonprofits organizations, observers have advocated the implementation of internal entrepreneurial actions as a response. Internal entrepreneurship--defined as risk taking, innovativeness, and proactiveness actions--are examined to determine what mechanisms are at work in promoting these actions among both managers and employees in organizations. Four organizations--two from each sector--were studied using a grounded theory approach, with semi-structured qualitative interviews performed with 15 managers and employees. Data analysis and coding resulted in a conceptual model that provides a parsimonious explanation of the mechanisms that promote entrepreneurial actions in organizations. Three key mechanisms that stem from …

LSU New Orleans Theses and Dissertations

The general goals of this study were to evaluate transplant methods for Lake Pontchartrain submersed aquatic vegetation (SAV) restoration, and to compare survival and expansion of transplanted SAV among four sites. Two experiments were conducted from summer 2000 through spring 2001 at two north shore and two south shore sites in Lake Pontchartrain. Experiment 1 involved testing the effects of transplanting with matting, staples, exclosures, and interspecific interaction on survival and expansion of Ruppia maritima and Vallisneria americana transplants in Lake Pontchartrain. Experiment 2 involved testing the effects of transplanting with matting, staples, and plugs on Ruppia survival and expansion. …

Art Therapy As A Measure Of Children’S Concept Of Surgery: A Preliminary Study, Emily C. Clark

EVMS School of Health Professions Theses & Dissertations

Surgery is a strange, and often frightening experience for children. A number of programs have been studied which attempt to prepare children for the surgery experience. Art therapy may be especially suited to help prepare children for surgery because art making is an effective form of communication for children, and can allow them to express their thoughts and fears about surgery. Unfortunately, studies of art therapy preparation programs are rare, and usually take the form of case studies. This research study is the first step in designing an art therapy preparation program for preparing children for surgery.

The purpose of …

Critical Features Of Antigen-Specific And Allospecific Recognition By Cytotoxic T Lymphocytes, Marc A. Frankenberry

Graduate Theses, Dissertations, and Problem Reports (ETD)

In general, CD8+ T lymphocytes respond to a single class I MHC/peptide complex, a phenomenon known as "MHC self-restriction". We previously reported that CD8+ CTLs from C57BL/6 mice were restricted to both H-2Kb and H-2Db when responding to the horse cyt c-derived peptide, p41--49. In Part I of this dissertation, we examine structural features of H-2Kb/cyt c and H-2Db/cyt c complexes responsible for dual recognition. B6.H-4.1c, a representative cloned CTL, was induced by similar concentrations of native peptide added to either H-2Kb- or H-2Db-expressing targets. Furthermore, the dissociation rates for both H-2Kb/cyt c and H-2D b/cyt c were comparable, but …

Role Of Hybridization In A Biological Invasion: An Experimental Study With Silene Latifolia, Lindsay Heaton

College of Graduate Studies: Theses & Dissertations

Biological invasions are now the second leading cause of loss of biodiversity. Recently, hybridization has been hypothesized as a mechanism for invasion success. The combination of individuals from different gene pools may create novel genotypes having increased invisibility. The goal of my research was to examine the role that intraspecific hybridization may play in invasion success by using the agricultural weed Silene latifolia as a model. I used a common garden experiment to examine whether crossing parents of different ancestry results in offspring with differing quality. Plants were pollinated in three treatments reflecting parent plants within the same population (P), …

Sounds From The Valley : A History Of The U.C./U.T.C. Band, 1923 To 1979, Charles Christian Leonard

Honors Theses

This writer found a frustration while researching and writing this history. The things one really wants to know about cannot usually be found. Will Durant wrote in The Story of Civilization: Civilization is a stream with banks. The stream is sometimes filled with blood from people killing, stealing, shouting, and doing things historians usually record-while, on the banks, unnoticed, people build homes, make love, raise children, sing songs, write poetry, whittle statues. The story of civilization is the story of what happens on the banks. You will find some interesting events in the following pages, but you will not find …

The Visual Perception Of Distance In Action Space., Bing Wu 1973-

Electronic Theses and Dissertations

This work examines our perception of distance within "action space" (about 2m ~ 30m), an ability that is important for various actions. Two general problems are addressed: what information can be used to judge distance accurately and how is it processed? The dissertation is in two parts. The first part considers the "what" question. Subjects' distance judgment was examined in real, altered and virtual environments by using perceptual tasks or actions to assess the role of a variety of intrinsic and environmental depth cues. The findings show that the perception of angular declination, or height in the visual field, is …

Foster Care Placement: Reducing The Risk Of Sibling Incest, David J. Herring

University of Michigan Journal of Law Reform

The Westermarck theory maintains that incest avoidance arises from the physical proximity of siblings during a critical period of early childhood. This proximity gives rise to an inhibiting effect on post childhood sexual interest. Two recent studies of sibling relationships have verified and refined the Westermarck theory, indicating that the critical period extends through the first four years of childhood. The theory and the studies have implications for child welfare laws, policies and practices surrounding the placement of siblings in foster care. Namely, the findings provide powerful reasons for placing siblings together during the critical period in order to minimize …

Age-Related Hearing Loss And Its Association With Reactive Oxygen Species And Mitochondrial Dna Damage, Michael D. Seidman, Nadir Ahmad, Dipa Joshi, Jake Seidman, Sujatha Thawani, Wayne S. Quirk

All Faculty Scholarship for the College of the Sciences

Age-related hearing loss, known as presbyacusis, is characterized by the progressive deterioration of auditory sensitivity associated with the aging process and is the leading cause of adult auditory deficiency in the USA. Presbyacusis is described as a progressive, bilateral, high-frequency hearing loss that is manifested on audiometric assessment by a moderately sloping pure tone audiogram. Approximately 23% of the population between 65 and 75 years of age, and 40% of the population older than 75 years of age are affected by this condition. It was estimated in 1980 that 11% of the population was 76 years or older and this …

Population Size And Movements Of Spotted Salamanders At South Holston Dam, Sullivan County, Tennessee., Eric Alexander Smith

Electronic Theses and Dissertations

In the Southern Appalachians, there are growing concerns about Spotted Salamanders (Ambystoma maculatum) due to habitat destruction and the uncertain future of their forested riparian habitat. In this study, I establish baseline data of a population of Spotted Salamanders so future monitoring of this population can be performed. The study site is located in northeastern Tennessee, just east of the city of Bristol. It is a vernal pond at the Osceola Island Recreation Area one mile below the South Holston Dam on Holston View Dam road. A drift fence was established completely around the perimeter of the vernal …

Modeled Sulfur Dioxide Exposure From A Proposed Coal Fired Power Plant, Using Geographic Information Systems And Air Dispersion Modeling, Steven Jason Hutchens

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study models the contribution of sulfur dioxide (SO 2) from a proposed coal fired power plant (CFPP) above existing ambient levels. Most vulnerable to SO2 exposure appear to be the elderly, young, and diseased, here identified as sensitive receptors (SR). Epidemiologic studies suggest 260mug/m3 as the lowest toxic threshold for SR exposure. It was hypothesized that added SO2 concentrations to existing ambient levels at regional sensitive receptors, under worst case scenario, would not exceed 260mug/m3.;The methods used identify and quantify density locations of localized SR using geographic information systems. Modeled worst case air dispersion concentration exposure to localized SR …
