Perceived Family Relationships Associated With Coming Out Of Mormon Male Homosexuals, Brad Benson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is one of the first to include data from both male homosexuals and their family members to investigate disclosure of sexual orientation. Being homosexual in U.S. society can be particularly traumatic for males because strong pressures oppose the violation of masculine gender norms. Being homosexual and Mormon has unique complications. Reactions from the Mormon community toward individuals of homosexual orientation is defined by prevailing attitudes toward homosexuality, which are largely based on existing theories of etiology, attribution of etiology, and the religious and cultural beliefs extant in the community. The role of family relationships in the coming out …

Energy, Fractal Movement Patterns, And Scale-Dependent Habitat Relationships Of Urban And Rural Mule Deer, Mark F. Mcclure

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I studied the behaviors, movement dynamics, habitat relationships, and population characteristics of Rocky Mountain mule deer (Odocoileus hemionus) using urban and rural winter ranges in Cache Valley, Utah, from January 1994 to February 1998. There were 2 goals to my research endeavors. The first was to assess how and why the behaviors and demographic characteristics of urban deer differed from those of rural deer. The second was to assess the scale-dependent responses to habitat and the scale-dependent patterns of habitat use by deer living in each area. To accomplish the first goal, I compared the prevalence of migration, the spatial …

Reproductive Allocation And Survival In Grasshoppers: Effects Of Resource Availability, Grasshopper Density, And Parasitism, David Heath Branson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A major challenge in ecology is to understand intraspecific variation in life histories. Variation in resource availability can lead to differences in reproductive allocation and life histories. Grasshoppers are a good organism for the study of variation in life histories, since they exhibit life history plasticity in response to biotic and environmental factors. An optimality model for grasshoppers was developed that predicts optimal total allocation to reproduction and optimal effort-per-offspring as functions of resource availability and mortality. Relative allocation to reproduction is predicted to increase with resource availability, while relative allocation to survival declines. A resource-based trade-off between egg size …

Rangeland Resources Monitoring: Concepts And Practical Applications, Benny R. Bobwski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

How does one person manage and monitor a half million acres of rangelands towards a sustainable future? Through a journey that begins with the understanding of sustainability, I explore the monitoring concept, two of its applications, and summarize with an emphasis on the art and science of management. Sustainability is a concept that confuses many managers because it is so complex. However, if one considers adaptability as the complement to sustainability, and realizes that an adaptable organism is a sustainable organism, then a manager can relate because the emphasis shifts from that of stability for the future to that of …

The Efficacy Of Plant Residue Degradation Products On Phosphorus, Iron, Iodine, And Fluorine Bioavailability To Plants, Cheryl L. Mackowiak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant and animal wastes degrade in soils to form relatively stable humified compounds, which form ion complexes that affect the bioavailability of elements in the soil solution. Hydroponic studies with wheat and rice were conducted to characterize the effect of humic acid (HA) on phosphorus (P), iron (Fe), fluorine (F), and iodine (I) bioavailability. Ferrihydrite [Fe(OH)₃] precipitation was greater on root surfaces without HA or synthetic chelates. Oxides such as ferrihydrite strongly adsorb P and provide exchange sites for metals. HA reduced this precipitate and increased P and Fe uptake.

Humic acid had no effect on F toxicity …

Establishing Reinforcing Properties In Neutral Stimuli Through Observational Learning With Children, Andrew Waine Gardner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to observe and analyze the factors that lead to a child's increase in responding to a previously neutral stimulus after observing another child's behavior and consequences in the same setting. The effects of five video presentations on rate of button-pressing responses were observed across four students. Rates of button-pressing behavior on an FR3 schedule of reinforcement were collected for each student using a computer and a metal apparatus with two flat push buttons. Each student completed two baseline phases to establish neutrality of stimuli, and viewed a total of five video presentations. Each video …

The Minnesota Multiphasic Personality Inventory-2 And Low Back Pain Surgery Outcome, David S. Shearer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chronic back pain is a serious problem in the U.S. for which about 10% of back pain sufferers will undergo elective surgery. Unfortunately, back surgery is not successful in alleviating back pain in a substantial number of surgery patients. Various psychological and psychosocial variables have a demonstrated relationship to back surgery outcome. The most widely used personality test used to predict back surgery outcome is the Minnesota Multiphasic Personality Inventory (MMPI). Past research has shown that elevations on three MMPI clinical scales (Hs, D, and Hy) are positively correlated with poor back surgery outcome. The current prospective study shows a …

The Effects Of Parental Modeling On The Health-Related Behaviors Of American Indian Adolescents: A Culturally Specific Investigation Of Social Learning Theory, Amy Jo Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Health-compromising behavior is a leading cause of death among American Indian (Al) adolescents. Examples of these behaviors include: smoking, alcohol consumption, drug use, and lack of seatbelt use. Theories that predict which Al youth are most at risk for executing these behaviors are needed.

Social learning theory (SL T) has shown adolescents' behaviors are sometimes highly correlated with their parents' behaviors across different ethnic groups. However, there has been little previous research done with Als.

The present study attempted to determine if SLT was applicable to Al adolescents and their parents with regard to four health-related behaviors: cigarette smoking, alcohol …

A Longitudinal Study Of Attention-Deficit/Hyperactivity Disorder Symptoms In Preschool-Age Children, Jessica Nicole Greenson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Attention-deficit hyperactivity disorder (ADHD) is among the most common reasons for referral to children's mental health clinics, with an estimated prevalence of 3% to 5% in the general population of school-age children. Children who exhibit the requisite behaviors may obtain a diagnosis of ADHD at any age; however, symptom onset must occur before age 7 and persist for at least 6 months. Despite these temporal requirements for diagnosis, little empirical information about the manifestation and stability of ADHD symptoms in preschool children exists. This study provides information about the initial presence and stability over one academic year of ADHD behaviors …

Effectiveness Of Earthen Escape Ramps In Reducing Big Game Mortality In Utah, Mary L. Hammer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One-way escape gates and earthen escape ramps are structures used to enable deer to exit the highway right-of-way along fenced roads. I compared the use of one-way escape gates and earthen escape ramps by mule deer on two highways in Utah to determine if deer exhibited a preference for either structure. Results showed that earthen escape ramps were used by mule deer 8-11 times more frequently than one-way gates. Highway mortality data suggest that the installation of the escape ramps likely reduced mortality of mule deer in both study locations, because we could not attribute reductions in mortality to decreased …

Intensification In A Risky Environment: The Case Of Improving Private Grazing Land For Beef Production In Utah, Louise D. Sainsbury

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah ranchers commonly face risks to their livelihoods. The objective of this work was to determine if ranchers could make profitable improvements to private land forage given the combined threat of low beef prices, drought, and possible loss of public grazing.

We used linear programming (LINDO) to identify the most profitable solutions for private land investment with an 11-year simulation. Operations were divided into small, medium, and large size classes. Various forage improvements and public permits were options. Two phases of a beef price cycle (peak and trough) and 2 precipitation patterns (wet and drought) were combined as joint favorable …

Structural And Geochemical Analyses Of Disseminated-Gold Deposits, Bald Mountain-Alligator Ridge District, Nevada: Insights Into Fault-Zone Architecture And Its Effect On Mineralization, K. Jill Hammond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Structural and geochemical analyses of the Top and Casino deposits, Bald Mountain-Alligator Ridge district, Nevada, were conducted to determine how structures affected gold deposition in Carlin-type deposit s. We also examined how permeability changed over time in a fault that cuts siltstone-dominated sedimentary rocks. The association of gold and related arsenic with faults at the margins of a Jurassic pluton and sedimentary rocks suggests that ore fluids migrated along faults and fracture s. Permeability of the faults changed over time within the Casino deposit, where the ore-controlling fault was a distributed conduit in the early stages of mineralization but a …

The Relationship Of Milk Urea Nitrogen And Dhia Production Variables In Western Commercial Dairy Herds, Rachael G. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Monthly individual cow DHIA test records (approximately 90,000) from 96 Holstein and Jersey herds from Utah, Idaho, and Montana were analyzed used the Mixed procedure in SAS to determine the relationships of milk production parameters to milk urea N (MUN). Records spanned two consecutive years ending December 2000. Means for Holsteins were 34.1 kg/d milk yield, 15.2 mg/dl MUN, 3.18% milk protein, 3.5% milk fat, and 280,000 somatic cell count. Mean MUN for Holsteins was lowest in fall (Oct.-Dec) and highest in winter and spring. Cows with highest milk protein percent (≥ 3.2%) had lowest MUN over all levels of …

Genetic Relationships Between Two Rare Plant Species, Aliciella Caespitosa And A. Tenuis, And Their Putative Progenitor, A. Subnuda, Carrie L. Mccracken

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Isolated populations have potential to become new species that should have less genetic variation than their ancestors. Small populations are more likely to lose genetic variation, which is, thus, expected to be greater in ancestors. Aliciella caespitosa and A. tenuis, two endemic species, may be derived from small populations of A. subnuda, a widespread species. Chloroplast DNA sequences were used to test this hypothesis. Allozyme data were used to compare genetic variation and numbers of alleles. Chloroplast data do not support the proposed relationships between A. subnuda and the other two species. Allozyme data were not more variable …

Visitor Capacity In The National Park System, Dr. Glenn E. Haas, National Park Service, U.S. Department Of The Interior

All U.S. Government Documents (Utah Regional Depository)

This paper reviews social science research on visitor capacity relevant to units of the National Park System (NPS). Visitor capacity is defined as a prescribed number and type of people that an area will accommodate given the desired natural/cultural resource conditions, visitor experiences, and management program. Some 40 years of scientific investigation illustrate the complexity of the interaction between human use and park resources. This paper provides insights from environmental psychology on person-environment relationships, nine capacity-related research findings, a matrix of NPS studies, and recommendations for a program of research.

Weed Control Methods Handbook: Tools & Techniques For Use In Natural Areas, Mandy Tu, Callie Hurd, John M. Randall, The Nature Conservancy

All U.S. Government Documents (Utah Regional Depository)

Invasive non-native plants are a serious threat to native species, communities, and ecosystems in many areas around the world. They can compete with and displace native plants, animals, and other organisms that depend on them, alter ecosystem functions and cycles significantly, hybridize with native species, and promote other invaders. The good news is that many plant invasions can be reversed, halted or slowed, and in certain situations, even badly infested areas can be restored to healthy systems dominated by native species. In most instances this requires taking action to control and manage those invasive plants. This handbook provides you with …

Reinventing The University: Literacies And Legitimacy In The Postmodern Academy, Christopher L. Schroeder

All USU Press Publications

Schroeder argues that, for students, postmodern instability in literacy and meaning has become a question of the legitimacy of current discourse of education. Schroeder is committed, then, to constructing literacies jointly with students and by so doing to bringing students to engage more deeply with education and society. To accomplish this, of course, he must advocate rebalancing instruction to a more radically student-centered curriculum. This does not mean he abandons traditional discourse or traditional practice in the classroom; rather, tradition becomes only one voice among many in the classroom, instead of being the dominating one. ReInventing the University is an …

(First Person)2: A Study Of Co-Authoring In The Academy, Kami Day, Michele Eodice

All USU Press Publications

In (First Person)2, Day and Eodice offer one of the few book-length studies of co-authoring in academic fields since Lunsford and Ede published theirs over a decade ago. The central research here involves in-depth interviews with ten successful academic collaborators from a range of disciplines and settings. The interviews explore the narratives of these informants' experience—what brought them to collaborate, what cognitive and logistical processes were involved as they worked together, what is the status of collaborated work in their field, and so on—and situate these informants within the broader discussion of collaboration theory and research as it has been …

Environmental Determinants Of Cost Sharing--An Application To Irrigation, David Aadland, Van Kolpin

Economic Research Institute Study Papers

Multiple-cost sharing rules often coexist in seemingly identical environments. We use shared irrigation costs as a context for examining the extent to which the structural environment explains the selection of a cost sharing rule. We find that environmental factors that-induce greater dependence on the cooperation of others, influence majority interests, create difficulties for interpersonal utility comparisons, or impact notions of "faimess"-all have impressive explanatory power. These results present the first formal empirical analysis of the manner in which structural features influence the actual cost-sharing choices of economic agents.

A Dynamic Analysis Of The Global Timber Market Under Global Warming: An Integrated Modeling Approach, Dug Man Lee, Kenneth S. Lyon

Economic Research Institute Study Papers

We developed a dynamic integrated modeling approach to identify the effect of global warming on the global timber market. The Timber Supply Model 2000, BlOME 3, and Hamburg were used as a suitable economic and ecological model. The TSM 2000 was adopted to model dynamic economic behavior in the global timber market. BlOME 3 was utilized as our steady state ecological model, and Hamburg as our general circulation model. The TSM 200 was developed to consider more important up-to-date components in the global timber market. We estimated dynamic ecological change based on the simulation results of BlOME 3 using Hamburg …
