Modulation Of The Host Response To Tacaribe Arenavirus Infection In Ag129 Mice By My-24, Eric Sefing

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

MY-24 is a new antiviral compound recently shown to protect immunocompromised mice from lethal challenge with Tacaribe virus (TCRV). Tacaribe virus is incapable of causing disease to humans, but is closely related to the highly pathogenic New World arenaviruses that cause often-fatal viral hemorrhagic fever syndromes. Remarkably, MY-24 prevents mortality without reducing virus burden in the circulation or tissues. To investigate the mechanism by which MY-24 protects AG129 mice against Tacaribe virus infection, we first characterized the natural history of disease in the model with an emphasis on host immune response and blood vessel function to establish the best times …

Examination Of Nonpoint Source Nutrient Export From A Snowfall-Dominated Watershed, Lindsey Deboer Carrigan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined nonpoint source pollution via tributaries to Pineview Reservoir. Since few literature values of export coefficients are available for snowfall-dominated watersheds such as Pineview, locally scaled rates were quantified using an upstream-downstream bracketing technique. Nitrogen and phosphorus grab samples were manually collected and discharge measurements were conducted during the annual study period. Additionally, high-frequency monitoring sensors that measured EC, temperature, turbidity, and water level were deployed at the up- and downstream sites to represent short-duration transport events and to examine watershed processes on a more representative time scale.

Daily nutrient loads were estimated from grab samples and flow …

Population Dynamics And Movements Of Translocated And Resident Greater Sage-Grouse On Anthro Mountain, Utah, Natasha W. Gruber

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Greater sage-grouse (Centrocercus urophasianus) populations have declined range-wide. Species translocations have been identified as a conservation strategy to augment declining populations in restored habitats. I evaluated protocols previously used to successfully translocate greater sage-grouse in Utah by comparing annual production, survival, habitat use, integration and seasonal movements of translocated birds and their chicks to the resident population. To conduct this study, I translocated 60 greater sagegrouse hens captured and radio-collared on Parker Mountain to Anthro Mountain in the spring of 2009 and 2010. I also captured and radio-collared 19 resident hens to serve as my control group. All …

Factors Influencing Relocation Success Of Utah Prairie Dog (Cynomys Parvidens), Rachel Curtis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah prairie dogs have been extirpated in 90% of their historic range due to introduced disease, eradication, and habitat destruction. Most of the population lives on private land where animals burrow in lawns and agricultural fields, which keeps this threatened species continually in conflict with landowners. The Utah Division of Wildlife Resources has been relocating prairie dogs from private to public land since the 1970s, but relocations have been largely unsuccessful due to high mortality. Prairie dogs are highly social animals, but they are usually relocated without regard to their family group, or coterie. Coteries typically consist of one reproductive …

The Application Of Tomographic Reconstruction Techniques To Ill-Conditioned Inverse Problems In Atmospheric Science And Biomedical Imaging, Vern Philip Hart Ii

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tomography is an imaging technique in which 3D models of objects are created from several 2D projections viewed at different angles. When the number of available projections is limited, the resulting data are said to be sparse. This restriction is often a direct result of the imaging geometry used to acquire the data. One-sided views and a small number of receivers can reduce the range of available projections, which makes the object more difficult to reconstruct. Approximate solutions to difficult imaging problems can be obtained using a class of iterative algorithms known as the algebraic reconstruction techniques (ARTs). The presented …

Dissociation Of The Role Of The Prelimbic Cortex In Interval Timing And Resource Allocation: Beneficial Effect Of Norepinephrine And Dopamine Reuptake Inhibitor Nomifensine On Anxiety-Inducing Distraction, Alexander R. Matthews, Olivia H. He, Mona Buhusi, Catalin V. Buhusi

Psychology Faculty Publications

Emotional distracters impair cognitive function. Emotional processing is dysregulated in affective disorders such as depression, phobias, schizophrenia, and PTSD. Among the processes impaired by emotional distracters, and whose dysregulation is documented in affective disorders, is the ability to time in the seconds-to-minutes range, i.e. interval timing. Presentation of task-irrelevant distracters during a timing task results in a delay in responding suggesting a failure to maintain subjective time in working memory, possibly due to attentional and working memory resources being diverted away from timing, as proposed by the Relative Time-Sharing model. We investigated the role of the prelimbic cortex in the …

Delayed Matching To Sample: Reinforcement Has Opposite Effects On Resistance To Change In Two Related Procedures, John A. Nevin, Timothy A. Shahan, Amy L. Odum, Ryan D. Ward

Psychology Faculty Publications

The effects of reinforcement on delayed matching to sample (DMTS) have been studied in two within-subjects procedures. In one, reinforcer magnitudes or probabilities vary from trial to trial and are signaled within trials (designated signaled DMTS trials). In the other, reinforcer probabilities are consistent for a series of trials produced by responding on variable-interval (VI) schedules within multiple-schedule components (designated multiple VI DMTS). In both procedures, forgetting functions in rich trials or components are higher than and roughly parallel to those in lean trials or components. However, during disruption, accuracy has been found to decrease more in rich than in …

Urban Trail System Planning In The Western United States: An Analysis Of The Trail-Specific Planning Efforts Of Four Cities That Have Implemented Urban Trail Systems, Kenneth C. Richley

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

States in the Western United States are growing at rates outpacing the rest of the nation. This growth is placing pressure on communities to develop their current open space for residential or commercial use. As cities develop a comprehensive open space plans, several elements arise. One critical element is connectivity. This connectivity is most often realized in the form of greenways. In many cities these greenways contain urban trail systems that provide significant recreation and connectivity benefits.

This thesis investigates the current recommended models used to plan for greenway, synthesizes them into a recommended model process, and analyzes case studies …

Behavioral Life-Cycle Models Under Alternative Demographic Regimes, Timothy F. Harris

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

Social security in the United States will encounter financial strains due to an aging population. The decreasing worker to retiree ratio will reduce retirement benefits relative to today’s benefits so long as the tax rate and eligibility age are not altered. Policy makers assume that they should make policies to maintain the current benefit levels.

In contrast to this assumption, this paper does not presume that policy makers should preserve current benefits. An analysis of the required tax rate to maintain lifetime utility across the current and future demographic regimes is undertaken rather than just a calculation of the tax …

Effects Of Choice Of Reinforcement On The On-­Task Behavior Of Kindergarten Students With Developmental Delays, Karen Binette

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

A high degree of external control is maintained in classrooms serving students with behavioral and developmental disabilities. However, decision making is an important developmental objective related to personal control and dignity. Choice making and discriminating preferred over less preferred outcomes is an important skill that is seldom taught to students with developmental disabilities. Previous research includes studies conducted in clinical settings or with populations with severe disabilities.

Early Experience Can Change The Structure Of The Body, Beth Burritt

All Current Publications

Why do animals eat certain foods and live in certain locations? Your first thought might be that they are born that way or it’s in their genes. While it is true that every animal is born with a set of genes that helps determine how it looks and what it needs to survive, genetics are only part of the story.

Demystifying The Cowboy Through His Song: How Cowboy Poetry And Music Create A Common Language Between Multiple-Use Conservationists And Forever-Wild Preservationists To Meet The Goals Of Sustainable Agriculture, Kristin Y. Ladd, Roslynn Brain

English Faculty Publications

Though multiple-use conservationists (use the land for multiple purposes) and forever-wild preservationists (solely set aside land for non-human species) seem to be at odds, this article argues that key figures such as Gifford Pinchot and John Muir discredit this perceived discordance. As well, it probes into the unexplored arena of cowboy music gatherings as productive places for cooperation between the two groups. First, mystique of the cowboy is examined and unraveled through true stories of cowboy-environmentalist collaboration. The article addresses how cowboy poetry festivals function as entertainment and meeting places to support sustainable behavior through communitybased social marketing techniques.

Manager's View: Sheep Creek Aspen Restoration

Tim Benedict

The intrigue of quaking aspen is shared by many because of colorful expression, soothing almost melodic sound, and biological diversity amid an ocean of conifers. Consider someday managing and researching aspen stands where restoration has never been tried and being able to claim, “A first.” When creating vision, it has been said, “Seek out partners that have similar goals and connect with a cause waiting to happen.” What you do today will be the history of tomorrow. That describes the spirit this project was launched with and today the Sheep Creek Aspen …

Gendered Socialization With An Embodied Agent: Creating A Social And Affable Mathematics Learning Environment For Middle-Grade Females, Yanghee Kim, Jae Hoon Lim

Instructional Technology and Learning Sciences Faculty Publications

This study examined whether or not embodied-agent-based learning would help middle-grade females have more positive mathematics learning experiences. The study used an explanatory mixed-methods research design. First, a classroom-based experiment was conducted with one hundred and twenty 9th-graders learning introductory algebra (53% male and 47% female; 51% Caucasian and 49% Latino). The results revealed that learner gender was a significant factor in the learners’ evaluations of their agent (η2 = .07), the learners’ task-specific attitudes (η2 = .05), and their task-specific self-efficacy (η2 = .06). In-depth interviews were then conducted with 22 students selected from the experiment participants. The interviews …

Using Dual Tasks To Test Immediate Transfer Of Training Between Naturalistic Movements: A Proof-Of-Principle Study, Sydney Y. Schaefer, Catherine E. Lang

Kinesiology and Health Science Faculty Publications

Theories of motor learning predict that training a movement reduces the amount of attention needed for its performance (i.e. more automatic). If training one movement transfers, then the amount of attention needed for performing a second movement should also be reduced, as measured under dual task conditions. The purpose of this study was to test whether dual task paradigms are feasible for detecting transfer of training between two naturalistic movements. Immediately following motor training, subjects improved performance of a second untrained movement under both single and dual task conditions. Subjects with no training did not. Improved performance in the untrained …
